The paper concentrates on trust as a research topic that receives increasing attention from
the side of different social disciplines.
The author of this thesis attempts to identify the reasons of this phenomenon, as well as
the decline in usage of the concepts conveying a congenial idea, such as, solidarity,
cooperation, social cohesion, social capital or connectedness. The key hypotheses, such
as paradigmatic change within the social sciences, emergence of risk society,
proliferation of the postmodem condition, new infonnation and communication
technologies and the crisis of democracy are considered through the works of the authors
who now mainly responsible for the shaping of the discourse of trust. The concepts of
Luhmann, Putnam, Sztompka, Fukuyama and Hardin are analyzed from an
epistemological viewpoint in its ontological and political implications.
The primary goal of the paper is to overview trust from the methodological viewpoint,
illustrating the limitations of the concept as a research strategy as weII as it advantages in
the epoch when the social sciences acquire a status of moral disciplines.

Green mould is a serious disease of commercially grown mushrooms, the causal agent
being attributed to the filamentous soil fungus Triclzodenna aggressivum f. aggressivu11l
and T. aggressivum f. ellropaellm. Found worldwide, and capable of devastating crops,
this disease has caused millions of dollars in lost revenue within the mushroom industry.
One mechanism used by TricllOdenlla spp. in the antagonism of other fungi, is the
secretion of lytic enzymes such as chitinases, which actively degrade a host's cell wall.
Therefore, the intent of this study was to examine the production of chitinase enzymes
during the host-parasite interaction of Agaricus bisporus (commercial mushroom) and
Triclzodemza aggressivum, focusing specifically on chitinase involvement in the
differential resistance of white, off-white, and brown commercial mushroom strains.
Chitinases isolated from cultures of A. bisporus and T. aggressivu11l grown together
and separately, were identified following native PAGE, and analysis of fluorescence
based on specific enzymatic cleavage of 4-methylumbelliferyl glucoside substrates.
Results indicate that the interaction between T. aggressivulll and A. bisporus involves a
complex enzyme battle. It was determined that T. aggressivum produces a number of
chitinases that appear to correlate to those isolated in previous studies using biocontrol
strains of T. Izarziallilm. A 122 kDa N-acetylglucosaminidase of T. aggressivu11l revealed
the highest and most variable activity, and is therefore believed to be an important
predictor of antifungal activity. Furthermore, results indicate that brown strain resistance
of mushrooms may be related to high levels of a 96 kDa N-acetylglucosaminidase, which
showed elevated activity in both solitary and dual cultures with T. aggressivum.
Overall, each host-parasite combination produced unique enzyme profiles, with the
majority of the differences seen between day 0 and day 6 for the extracellular chitinases.
Therefore, it was concluded that the antagonistic behaviour of T. aggressivli1ll does not
involve a typical response, always producing the same types and levels of enzymes, but
that mycoparasitism, specifically in the form of chitinase production, may be induced and
regulated based on the host presented.

This study examined the influence of training on Asian learners' beliefs,
interaction, and attitudes during collaborative learning (CL) and explored the processes of
their CL in pairs. The literature contains few studies on the effect of collaborative training
in language learning. In addition, it shows gaps between SLA theory and practice
resulting from learners' cultural differences. Although second/subsequent language
acquisition (SLA) theory assumes that CL contributes to language learning, implementing
CL in a multicultural classroom is often considered to be unsuccessful by teachers. The
research questions designed to address this gap explore: (a) the extent to which tra~ng
affects Asian learners' attitudes towards and interaction during CL; (b) how Asian learners
accomplish collaborative tasks in pairs.
In the quasi-experimental research design, the learners in the treatment group
received special training in CL for 5 weeks while the learners in the comparison group did
not receive similar training. Data were collected from 45 McMaster University students
through pre- and posttests, pre- and postintervention questionnaires, student information,
and informal classroom observations. To detennine the influence of training, the
frequency of communication units (c-units), Language Related Episodes (LREs),
Collaborative Dialogue (CD) from audio-taped data, and the fmal draft scores were
compared between pre- and posttests. The learners' pre- and postintervention
questionnaires were also compared. Transcripts from audio-taped data, students'
information, their responses and comments from questionnaires, and informal observations
served to investigate the processes of Asian learners' CL.
Overall, this study found that training had significant influence on the frequency of
c-units and CD, and considerable impact on the draft scores, although little influence on the frequency of LREs was observed. The results from the questionnaires in the treatment
group showed positive changes in the learners' beliefs on pair work after training. On the
other hand, analyses of the transcription data showed that the learners did not conduct
enough discussion for a resolution of problems with peers.
In conclusion, results suggested the need for teacher intervention, a longer period
of collaborative training, and an implementation of self-evaluation into the course grade to
encourage the learners to succeed in collaborative learning.

This qualitative study examined collective learning within nursing clinical groups.
Specifically, it explored the influence of the individual on the group and the impact of the
group on the individual. The study was organized using the concepts from Debbie
Kilgore's theory of collective learning (1999).
The sample consisted of 1 8 second-year university nursing students and 3 clinical
instructors. Data were collected via individual interviews with each participant and
researcher's observations during a group conference. The interviews were tape-recorded,
transcribed, and analyzed using key concepts from Kilgore's framework. Several
interesting findings emerged.
Overall, it appeared that individual components and group components
contributed to the quality and quantity of collective learning that occurred in the groups.
Individually, each person's past group experiences, personality, culture, and gender
influenced how that individual acted in the group, their roles, and how much influence
they had over group decisions. Moreover, the situation which seemed to cause the
greatest sense of helplessness and loss of control was when one of their group members
was breaking a norm. They were unable to deal with such situations constructively. Also,
the amount of sense of worthiness (respect) and sense of agency (control) the member felt
within the group had an impact on the person's role in group decisions. Finally, it seemed
that students felt more connected with their peers within the clinical setting when they
were close with them on a personal and social level.
With respect to the group elements, it seemed that the instructors' values and way
of being were instrumental in shaping the group's identity. In group 2, there were clear examples of group consciousness and the students' need to go along with the majority
viewpoint, even when it was contrary to their own beliefs. Finally, the common goal of
passing clinical and dealing with the fears of being in the clinical setting brought
solidarity among the group members, and there seemed to be a high level of positive
interdependence among them. From the discussion and analysis of the findings,
recommendations were given on how to improve the learning within clinical groups.

Numerous definitions of forgiveness have been proposed in the literature (e.g.. North, 1987;
Enright, Freedman & Rique, 1998), most ofwhich are based on religious or philosophical
notions, rather than on empirical evidence. Definitions employed by researchers have typically
set very high standards for forgiveness. This research was designed to investigate the
possibility that these definitions describe an ideal of forgiveness and may not reflect
laypersons' beliefe and experiences. Using Higgins' Self-Discrepancy Theory as a fiamework,
three types of forgiveness beliefs were investigated: actual, ideal, and ought Q-methodology
(which permits intensive study ofphenomena in small samples) was employed to examine and
compare participants' beliefs about forgiveness across these domains. Thirty participants (20
women), 25 to 78 years of age, were recruited firom the community. They were asked to sort a
set of66 statements about forgiveness according to their level of agreement with each
statement This process was repeated three times, with the goal of modelling participants'
actual experiences, their ideals, and how they believed forgiveness ought to be. Three
perspectives on forgiveness emerged across the domains: forgiveness as motivated by
religious beliefs, reconciliation-focussed forgiveness, and conflicted forgiveness. These
perspectives indicated that, for many participants, the definitions presented in the literature
may coincide with their beliefs about how forgiveness would ideally be and should be, as well
as with their experiences of forgiveness; however, a large number of participants' experiences
of, and beliefs about, forgiveness do not conform to the standards set out in the literature, and
to exclude these participants' experiences and beliefs would mean overlooking what
forgiveness means to a large portion of people. Results of this study indicate that researchers
need to keep an open mind about what forgiveness may mean to their participants.

During the 1980's and for much of the 1990's, many countries in the Asia Pacific
were renowned for their economic development and prosperity. The Asian tigers were a
source of great interest for many economists and international investors. The 1997 Asian
financial crisis, however, dramatically altered the growth and the performance of these
economies. The crisis sent several ofAsia's best performing economies on a downward spiral
from which many have yet to fully recover. The crisis exposed the financial and the political
weaknesses ofmany countries in the region. Moreover, the crisis severely affected the wellbeing
and the security ofmany ofthe region's citizens.
This text will examine the economic crisis in greater detail and explore current debates
in the study of international relations theory. More specifically, this paper will examine
recent challenges posed to traditional international relations theory and address alternative
approaches to this field of study. This paper will examine Critical theory and its role in
shifting the referent object of security from the state to the individual. In this context, this
paper will also assess Critical theory's role in enabling such issues as gender and human
security to find a place on the agendas of international relations scholars and foreign policy
makers. The central focus ofthis study will be the financial crisis and its impact on human
security in the Southeast Asia. Furthermore, this paper will assess the recovery efforts ofthe
domestic governments, international organizations and various Canadian sponsored
initiatives in the context ofhuman security.

The media tends to represent female athletes as women first and athletes second
(Koivula, 1 999). The present study investigated whether this same trend was present for
female sportscasters, using a self-presentational framework. Self-presentation is the
process by which people try to control how others see them (Leary, 1995). One factor
that may influence the type of image they try to project is their roles held in society,
including gender roles. The gender roles for a man include dominance, assertiveness, and
masculinity, while the gender roles for a woman include nurturer, femininity, and
attractiveness (Deaux & Major, 1 987). By contrast, sports broadcasters are expected to be
knowledgeable, assertive, and competent. Research suggests that female sports
broadcasters are seen as less competent and less persuasive than male sports broadcasters
(Mitrook & Dorr, 2001; Ordman & Zillmann, 1994, Toro, 2005). One reason for this
difference may be that the gender roles for a man are much more similar to those of a
sportscaster, compared to those of a woman. Thus, there may be a conflict between the
two roles for women. The present study investigated whether the gender and perceived
attractiveness of sportscasters influenced the audience's perceptions of the level of
competence that a sportscaster demonstrates.
Two hundred and four male (n =75) and female (n =129) undergraduate students
were recruited from a southern Ontario university to participate in the study. The average
age of the male participants was 21 .23 years {SD =1 .60), and the average age for female
participants was 20.67 years {SD = 1 .31). The age range for all participants was from 19
to 30 years {M = 20.87 years, SD = 1 .45). Af^er providing informed consent, participants
randomly received one of four possible questionnaire packages. The participants answered the demographic questionnaire, and then proceeded to view the picture and
read the script of a sports newscast. Next, based on the picture and script, the participants
answered the competence questionnaire, assessing the general, sport specific, and overall
competence of the sportscaster. Once participants had finished, they returned the package
to the researcher and were thanked for their time.
Data was analyzed using an ANOVA to determine if general sport competence
differs with respect to gender and attractiveness of the sportscaster. Overall, the ANOVA
was non-significant (p > .05), indicating no differences on the dependent variable based
on gender (F (3, 194) = .631, p = .426), attractiveness (F (3, 194) = .070, p = .791), or the
interaction of the two {F (3, 194) = .043,/? = .836). Although none of the study
hypotheses were supported, the study provided some insight to the perceived competence
of female sportscasters. It is possible that female sportscasters are now seen as competent
in the area of sports. Sample characteristics could also have influenced these results; the
participants in the current study were primarily physical education and kinesiology
students, who had experience participating in physical activity with both men and
women. Future research should investigate this issue further by using a video sportscast.
It is possible that delivery characteristics such as voice quality or eye contact may also
impact perceptions of sportscasters.

Currently, few studies address what kindergarten children think about bullying
behaviour and explore whether or not they perceive bullying as a prevalent concern in
their day-to-day school activities. This study described 15 Canadian kindergarten
students' graphic and narrative representations (drawings and stories) of their bullying
experiences. The content of students' drawings and stories were analyzed to explore how
kindergarten children perceived bullying within the context of their lives. Coding
categories were developed to analyze the kindergartners' perceptions, and emerging
themes were also explored. In general, findings showed that kindergartners perceive
bullying situations as occurring during one-to-one peer interaction and not within social
group situations. Results are discussed in relation to educational implications.

Research suggests that self-blame attributions are important in the process of
adjustment to negative life events. Much of the research originates from JanofTBulman's
(1979) theory regarding behavioural and characterological self-blame. She
argued that attributing negative events to one's behaviour is adaptive because
behavioural self-blame involves attributions to a modifiable source, which implies that a
similar event can be avoided in the future. In contrast, attributing negative events to
one's character is believed to be maladaptive because character is seen as relatively
stable and unmodifiable.
Unfortunately, the empirical literature does not show consistent relations between
these two types of self-blame attributions and well-being as predicted by Janoff-Bulman.
For this thesis, I proposed that one reason for this inconsistency is that Janoff-Bulman's
assumption about the perceived modifiability of behavioural versus characterological
causes is incorrect — people often dlo perceive character (as well as behaviour) to be
modifiable.
Sixty-two participants completed a questionnaire regarding a recent negative life
event and its impact on their well-being. Consistent with my argument, I found that both
behavioural and characterological self-blame attributions following a negative life event
were seen as modifiable. As hypothesized, perceived modifiability of causes v^as related
to well-being. For example, overall modifiability was related to greater coping efficacy,
less social dysfunction, less severe depression, and greater positive affect; however.
contrary to predictions, the relation between perceived modifiability of causes and wellbeing
was not mediated by the perception that similar events could be avoided in the
future.
Individual differences in attributional style were also assessed in this study. An
attributional style that tended to be more internal, stable, and specific was related to wellbeing
as expected; however, neither the perceived modifiability of blame attributions nor
the perceived avoidability of similar future events mediated this relation. Implications
for professionals dealing with trauma victims and potential directions for future research
are discussed.

The quality of the mother-child relationship was examined in relation to joint planning,
maternal teaching strategies, maternal emotional support, mutual positive affect and
attachment security. Fifty-five grade five children and their mothers participated in a
laboratory session comprised of various activities and completed questionnaires to
evaluate attachment security. Joint planning and social problem solving were assessed
observationally during an origami task. Problem solving effectiveness was unrelated to
maternal teaching strategies, maternal encouragement and mutual positive affect. A
marginally significant relationship was found between maternal encouragement and
active child participation. Attachment security was found to be significantly related to
sharing of responsibility during local planning, but only for child autonomous
performance. An examination of conditional probabilities revealed that mutual positive
affect did not increase the likelihood of subsequent mother-child dyadic regulation.
However, mutual positive affect was found to be significantly related to both active child
participation and dyadic regulation. The hypothesis predicting a mediational model was
not supported. The implications of these findings in the theoretical and empirical
literature were considered and suggestions for future research were made.

This qualitative study examined the effects of hospital restructuring on a group of
nurses at a community hospital. Eleven nurses were asked questions in order to gain
insight into their experience in this situation. Ten of these participants were female,
and one was male. The intent was to gather information about how restructuring has
affected their lives, including, their motivational factors and barriers to participation
in continuing education, and their descriptions of their workplace environment.
Audiotaped interviews were conducted on two occasions to obtain this data. Emergent
themes included the nurses' comments about continuing education, motivational
factors, barriers that included geography and time, reactions of co-workers,
restructuring, the College of Nurses' Quality Assurance Program including peer
feedback, and performance appraisals. The literature review compares the barriers and
motivational factors to the previous research findings. Thus, this study gave voice to
the experience of this group of nurses, working in a healthcare setting that is involved
in restructuring. This information is important to the healthcare system, since many
areas are involved in restructuring. The whole process, if it is to be successful,
depends on the frontline workers, namely the nurses. Thus, if there is anything to be
learned from this group of people, that could be used to improve this progression,
everyone would benefit from this information, were it to be implemented. Everyone is
a stakeholder in the quality of healthcare in our province. The frontline workers are
the ones that hold the vantage point to be able to provide suggestions for the changes
needed to successful. These nurses are not just motivated by work issues however,
and educating them and motivating them will also improve the care provided through
increased knowledge and enhanced self-esteem.

Abstract:
In Imperial Eyes Mary Louise Pratt (1992: 7, emphasis original) defines autoethnography
as "instances in which colonized subjects undertake to represent themselves in ways that
engage with the colonizer's own terms ... in response to or in dialogue with . .
.
metropolitan representations." Although Pratt's conceptualization of autoethnography has
much to offer post-colonial studies, it has received little attention in the field. In this
thesis, I interrogate Pratt's notion of autoethnography as a theoretical tool for
understanding the self-representations of subordinate peoples within transcultural terrains
of signification. I argue that autoethnography is a concept that allows us to move beyond
some theoretical dualisms, and to recognize the (necessary) coexistence of subordinate
peoples' simultaneous accommodation of and resistance to dominant representations of
themselves. I suggest that even when autoethnographic expressions seem to rely on or to
reproduce dominant knowledges, their very existence as speech acts implicitly resists
dominant discourses which objectify members of oppressed populations and re-create
them as Native Informants. I use Pratt's concept to analyze two books by Islamic feminist
sociologist Fatima Memissi. Memissi's Dreams ofTrespass and Scheherazade Goes
West illustrate the simultaneity of accommodation and disruption evident in
autoethnographic communication. Across the two books, Memissi shows herself
renegotiating the discourses which discipline her (and her speech). She switches back and
forth between the positions of reader and author, demonstrates the reciprocity of the
disciplinary gaze (she looks back at her dominants, reading their own reading of her
representation of her social group), and provides a model of autoethnographic dialogue.

Community service participation can have a positive impact on development,
especially for youth. Although researchers have found positive outcomes, there has been
a notable decline in youth participation over the past few years (Statistics Canada, 2000).
Given the positive outcomes and current decline, it has been argued that youth should be
encouraged to get involved in service activities. In the present study, quantitative and
qualitative data were collected to determine factors that would help youth to initiate and
sustain service, along with examining the quality of their experience. Eighty-two
university undergraduate students (23 men), ranging in age from 17-20 years completed a
60-minute self-report questionnaire. Initiating and sustaining factors, motivational
systems (similar to approach and avoidance dimensions), activity dimensions {Structure,
Supportive Social Environment), quality of experience {Positive, Stress-Challenge), and
future intention to participate in community service were measured. Eight participants
also completed a 20-minute telephone interview to complement and expand on the
quantitative data collected.
Some initiating and sustaining factors were specific to individuals higher on the
avoidance dimension, while others were relevant to those higher on the approach
dimension. Several factors also were important to individuals regardless of their
motivational system orientation. Positive quality of experience was related positively to
experiencing a supportive social environment. In addition, women rated their community
service as more positive than did men. A predicted interaction between the avoidance
dimension and Structure in predicting positive quality of experience was not supported;
however, positive quality of experience was predicted by the interaction of the approach
dimension and Structure. A tested interaction between the avoidance dimension and
Supportive Social Environment in predicting positive quality of experience was not
supported. Similarly, a predicted interaction between the approach dimension and
Supportive Social Environment in predicting positive experience quality was not
supported. However, Supportive Social Environment was positively related to positive
quality of experience. No support was found for a mediational role for positive quality of
experience or stress-challenge quality of experience in exploring the relation between
motivational orientation and fiiture intention to engage in service activities.
The results of this study suggest that participating in a service environment that is
supportive and provides the opportunity for social interactions with others would promote
positive quality of experience and help youth sustain involvement. Thus, to help youth
have positive experiences and to remain active in service, it is important for service
agencies to promote these types of environments. In addition, some initiating and
sustaining factors were specific to youth higher on the avoidance dimension and some
were relevant to youth higher on the approach dimension. Therefore, service agencies
may need to consider using different recruitment and retention strategies, depending on
the type of youth they wish to recruit.

The deoxy derivative of pancratistatin 1.10 was prepared in good yield through
the use of a [4+2] Diels-Alder cycloaddition and Bischler-Napieralski cyclization
approach. The Bischler-Napieralski cyclization was shown to yield two additional side
products 2.9, 2.10, however, under slightly modified hydrolysis conditions, the
tetracyclic product 2.11 was obtained exclusively in greater than 84% yield. Initial
screening of the di-hydroxylatgd derivative, and the other complementary pair
analogue 1.10' previously prepared in our laboratories gave interesting results. Both of
these compounds were shown to exhibit cytostatic activity; the mono-alcohol was
marginally active while the di-hydroxylated analogue proved to be more potent
although one to two magnitudes less potent than pancratistatin itself Human tumour
cell line assay results indicated that the di-hydroxylated derivative exhibited selective
cytotoxic inhibition in the following cell lines: non-small cell lung cancer line
NCI-H226 (ED50 - 0.65 ^g/mL), leukemia cell lines CCRF-CEM (ED30 = 0.55
Hg/mL) and HL-60(TB) (ED50 = 0.89^ig/mL). Our results demonstrated that the
pharmacophore is not a mono-alcohol, and that the minimum pharmacophore contains
the hydroxyl group at the C4 position in addition to either, or both, of the hydroxyl
groups present at C2 and C3.' The minimum pharmacophore has been narrowed to only
three possibilities which are current synthetic targets in several research groups. The controlled Grignard addition to the tartaric acid derived bis-Weinreb
amide 1.25 afforded a direct entry to a host of 1,4-diflferentiated tartaric acid derived
intermediates (2.12-2.18). This potentially usefiil methodology was demonstrated
through the efficient synthesis of the naturally occurring lactone 2.23, which bears the
inherent syn-dio\ subunit. Based on this result, a similar approach to the synthesis of
syn-dio\ bearing natural products looks very promising? A direct 2,3-diol desymmetrization method using TIPS-triflate was shown to be
effective on the selective differentiation of Z,-methyl tartrate (and diisopropyl tartrate).
The mono-silyl-protected intermediates 2.31 also proved to be useful when they were
selectively differentiated at the 1,4-carboxyl position (2.35, 2.36) through the use of a
borohydride reducing agent. Furthermore, the mono-silyl-protected derivative
underwent periodate cleavage affording two synthetically useful a,P-unsaturated
esters 2.43, 2.44, with one of esters being obtained via a silyl-migration method.''

This study explored the concept of a spiritual retreat for frontline employees of a
large corporate call centre. During a 1 day retreat, 4 call centre employees were
introduced to various meditation and retreat activities. Follovsdng the retreat the
participants were asked to incorporate the various meditations and activities into their
workplace. The participants kept journals throughout the study in an effort to determine
what occurred when these practices were transferred from the retreat setting to the
workplace.
This study examined how a working spirituality enhances one's sense of
fulfillment, defined by certain critical elements: relationship, awareness, ritual, internal
commitment, and choice. Although the retreat was a successful means of exploring these
elements, the degree to which each employee could benefit from them was determined by
the extent of their internal commitment not only to themselves, but also to their jobs.

All-electron partitioning of wave functions into products ^core^vai of core and valence
parts in orbital space results in the loss of core-valence antisymmetry, uncorrelation of
motion of core and valence electrons, and core-valence overlap. These effects are studied
with the variational Monte Carlo method using appropriately designed wave functions
for the first-row atoms and positive ions.
It is shown that the loss of antisymmetry with respect to interchange of core and
valence electrons is a dominant effect which increases rapidly through the row, while the
effect of core-valence uncorrelation is generally smaller. Orthogonality of the core and
valence parts partially substitutes the exclusion principle and is absolutely necessary for
meaningful calculations with partitioned wave functions. Core-valence overlap may lead
to nonsensical values of the total energy.
It has been found that even relatively crude core-valence partitioned wave functions
generally can estimate ionization potentials with better accuracy than that of the traditional,
non-partitioned ones, provided that they achieve maximum separation (independence)
of core and valence shells accompanied by high internal flexibility of ^core
and Wvai- Our best core-valence partitioned wave function of that kind estimates the
IP's with an accuracy comparable to the most accurate theoretical determinations in the
literature.

National governments, the United Nations, and other organizations have deemed sport
and other means of physical activity such as recreation, games and play for development
a useful means for addressing a wide range of problems in communities and more
specifically, providing youth with an opportunity to experience the benefits of physical
activity. There is a need for research that furthers our understanding of how participants
experience these programs. Specifically, the purpose of this study, was to better
understand the lived experiences of the participants in a YMCA camp program that
integrated physical activity and play for the specific development of poor youth street
workers. A phenomenological approach infonned by a critical perspective (Creswell,
2003; Rossman & Rallis, 2003) was used. The study took place through the Asociaci6n
Cristiana de J6venes de Costa Rica (ACJ) in Central America. The focus was on a camp
program and the lived experiences of six purposefully chosen, youth street workers
between the ages of 13-17. Their experiences were explored through semi-structured
interviews. Other data that fonn the study include: field notes, observations, a reflexive
journal and document analysis. The findings that emerged from the data include main
themes of relationships, poverty, personal change and empowennent. For many youth,
the ACJ is a relatively safe place to play, to "detach," their minds, to "distract" and
"disorient" themselves from their dysfunctional families, violent neighbourhood, the
poverty they live in, and from the necessity of having to work in the street to supplement
the family income. Although many studies have shown that programs that include
physical activity, play and/or sport have a positive impact on youth with regard to
healthy development and improvements in well-being, there has been little work done to
address the voices and experiences of the youth that participate in these programs. Using
an interpretive-critical approach, this study focused on the participants' personal
backgrounds, their experiences within the program and their critical reflections on the
program. This study draws from a phenomenological philosophy and method to report
findings from participants in an ACJ program in Costa Rica. This research shows how
these youth were given the opportunity to use the program and the ACJ property as a
relatively safe place to play, to behave like the youth they are, to establish and maintain
their friendship networks, and develop empathy and conflict resolution skills. The
fmdings from this study reveal how by participating in the ACJ program they each
described a personal change, wherein they felt empowered to learn they could positivel y
control themselves and as a result positively affect their own futures. These fmdings
contribute knowledge surrounding the lived experiences of youth in developmental
programs that use physical activity.

In 2002, The Ontario Federation of School Athletic Associations (OFSAA)
identified that in providing extracurricular sport programs schools are faced with the
'new realities' of the education system. Although research has been conducted
exploring the pressures impacting the provision of extracurricular school sport
(Donnelly, Mcloy, Petherick, & Safai, 2000), few studies within the field have
focused on understanding extracurricular school sport from an organizational level.
The focus of this study was to examine the organizational design (structure, systems,
and values) of the extracurricular sport department within three Ontario high schools,
as well as to understand the context within which the departments exist.
A qualitative multiple case study design was adopted and three public high
schools were selected from one district school board in Ontario to represent the cases
under investigation. Interviews, observations and documents were used to analyze
the extracurricular sport department design of each case and to better understand the
context within which the departments exist. As the result of the analysis of the
structure, systems and values of each case, two designs emerged- Design KT1 and
Design KT2. Differences in the characteristics of design archetype KT1 and KT2
centered on the design dimension of values, and therefore this study identified that
contrasting organizational values reflect differences in design types. The
characteristics of the Kitchen Table archetype were found to be transferable to the
sub-sector of extracurricular school sport, and therefore this research provides a springboard for further research in organizational design within the education sector
of extracurricular high school sport.
Interconnections were found between the data associated with the external and
internal contexts within which the extracurricular sport departments exist. The
analysis of the internal context indicated the important role played by organizational
members in shaping the context within which the departments exist. The analysis of
the external context highlighted the institutional pressures that were present within
the education environment. Both political and cultural expectations related to the role
of extracurricular sport within schools were visible and were subsequently used by
the high schools to create legitimacy and prestige, and to access resources.

There has been and will continue to be substantial debate over how the international system
can best be characterized. The objective of this paper is to demonstrate that the
international system can best be characterized by the essential features of realism, but the
use of realist policy prescriptions are inadequate when applied independently to deal with
the threat of terrorism as it exists today. In order to demonstrate this an examination of
realism in the international system, U.S. foreign policy, and case analysis of Afghanistan
and Iraq will be undertaken to demonstrate that although realist policy prescriptions do
have a role in dealing with modem transnational security threats, these prescriptions on
their own are inadequate when dealing with terrorism.

Although capacity has been used in recent federal government accords and
policies related to the voluntary and amateur sport sectors, there is little consensus over
the meaning of the term. Consequently, the purpose of this qualitative case study was to
explore the concept of organizational capacity within a temporary voluntary sport
organization. Specifically, the nature of organizational capacity was examined within the
case of the Volunteers Division of the 2005 Canada Summer Games (CSG) Host Society.
Data were collected from executive planning and middle management CSG volunteers
through the use of a variety of methods: verbal journals, interviews, observations,
documents and a focus group. Findings indicated several challenges associated with the
volunteer management model utilized by the host society, varying levels of importance
among six elements of capacity, and key aspects of the relationship between
organizational capacity and transformational development. Implications focused upon the
importance of highlighting individuals rather than the organizational as a whole in order
to build capacity, and utilizing a brain or hybrid brain-machine organizational form to
enhance capacity. Recommendations are provided for both the Canada Games Council
and Canada Games host societies.

In the past two decades numerous programs have emerged to treat individuals with
developmental disabilities who have sexual offending behaviours. There has, however
been very few studies that systematically examine the effectiveness of long term
treatment with this population. The present research examines the therapeutic outcomes
of a multi-modal behaviour approach with six individuals with intellectual disabilities
previously charged with sexual assault. The participants also exhibited severe
behavioural challenges that included verbal aggression, physical aggression, destruction
and self-injury. These six participants (5 males, 1 female) were admitted to a Long Term
Residential Treatment Program (LTRTP), due to the severity of their behaviours and due
to their lack of treatment success in other programs. Individualized treatment plans
focused on the reduction of maladaptive behaviours and the enhancing of skills such as
positive coping strategies, socio-sexual knowledge, life skills, recreation and leisure
skills. The treatment program also included psychiatric, psychological, medical,
behavioural and educational interventions. The participants remained in the Long Term
Residential Treatment Program (LTRTP) program from 181 to 932 days (average of 1.5
years). Pre and post treatment evaluations were conducted using the following tools:
frequency of target behaviours, Psychopathology Inventory for Mentally Retarded Adults
(PIMRA), Emotional Problems Scale (EPS), Socio-Sexual Knowledge and Attitudes
Assessment Tool (SSKAAT-R) and Quality of Life Questionnaire (QOL-Q). Recidivism
rates and the need for re-hospitalization were also noted for each participant. By offering
high levels of individualized interventions, all six participants showed a 37 % rate of
reduction in maladaptive behaviours with zero to low rates of inappropriate sexualbehaviour, there were no psychiatric hospitalizations, and there was no recidivism for 5
of 6 participants. In addition, medication was reduced. Mental health scores on the
PIMRA were reduced across all participants by 25 % and scores on the Quality of Life
Questionnaire increased for all participants by an average of 72 %. These findings add to
and build upon the existing literature on long term treatment benefits for individuals with
a intellectual disability who sexually offend. By utilizing an individualized and multimodal
treatment approach to reduce severe behavioural challenges, not only can the
maladaptive behaviours be reduced, but adaptive behaviours can be increased, mental
health concerns can be managed, and overall quality of life can be improved.

By relying on existing cultural models, the Victorian spa promoted health
and wellness. Advertising, together with other forms of promotion, strengthened the
legitimacy of its claims to cure a variety of health problems. By the use of some links to
science and a mystical folk belief about the efficacy of the local mineral waters, three
spas emerged in St.Catharines: the Stephenson House, the WeIland House, and the
Springbank. As the twentieth century approached, the spa movement declined and
institutionalized medicine struggled to establish a monopoly on health care. This thesis
argues that the health spas in St. Catharines occupied that transitional space in nineteenth
century medicine between home remedy and hospital.
The interplay between scientific discovery and business enterprise produced a
climate in which the Victorian health resort flourished. This phenomenon, combined with
the various maladies brought on by industrialization, nineteenth-century lifestyle, and the
absence of medical options, created a surge in the popularity of health spas and mineral
spring therapies.
By the tum of the twentieth century, interest in mineral water treatments had
declined. The health resorts that had blossomed between 1850 and 1899 began to
experience a serious decrease in business. This popular movement became outmoded in
the face of emerging medical and scientific knowledge. In St. Catharines, the last resort
to remain standing, the WeIland House, finished out the city's spa era as a hospital.

Autism is a developmental disorder that is characterized by abnonnal social interactions and
communications as well as repetitive and restricted activities and interests. There is evidence of a
genetic component, as 5% of younger siblings are diagnosed if their older sibling has been
diagnosed. Autism is generally not diagnosed until age 3 at the earliest, yet it has been shown that
early intervention for children with autism can greatly increase their functioning. Because of this, it
is important that symptoms of autism are identified as early as possible so that diagnosis can occur as
soon as possible to allow these children the earliest intervention.
This thesis was divided into two parts. The first looked at the psychometrics of two proposed
measures, the Parent Observation Checklist (POC), administered monthly, and the Infant Behavior
Summary Evaluation (mSE), administered bimonthly, to see if they can be used with the infant
population to identify autistic symptoms in infants who are at high risk for autism or related
problems because they have an older sibling with autism. Study 1 reported acceptable psychometric
properties of both the POC and IBSE in terms of test-retest reliability, internal consistency, construct
validity and predictive validity. These results provide preliminary evidence that parent report
measures can help to detect early symptoms of ASD in infants. The POC was shown to differentiate
infants who were diagnosed from a matched group that was not diagnosed by 3 years of age.
The second part of this thesis involved a telephone interview of parents who reported
developmental and/or behavior problems in their high-risk infants that may be early signs of Autism
Spectrum Disorder (ASD). During the interview, a service questionnaire was administered to see
what interventions (including strategies recommended by the researchers) their at risk infants and
affected older siblings were receiving, how satisfied the parents were with them and how effective
they felt the interventions were.
3
Study 2 also yielded promising results. Parents utilized a variety of services for at risk infants
and children with ASD. The interventions included empirically validated early intervention (e.g.,
ABA) to non-empirically validated treatments (e.g., diet therapy). The large number of nonempirically
validated treatments parents used was surprising, yet parents reported being involved and
satisfied, and thought that the services were effective. Parents' perceptions of their stress levels went
down slightly and feelings of competence rose when they accessed services for their infants.
Overall, the results of this thesis provide new evidence that parent-report methods hold
promise as early detection instruments for ASD in at-risk infants. More research is needed to further
validate these instruments as well as to understand the variables related to the parents' choice of
early intervention for their at risk and affected children.

Self-presentation has been identified as playing a key role in the perfonnance of
various potentially hazardous health behaviours such as substance abuse, eating disorders
and reckless behaviours (Leary, Tchividjian, & Kraxberger, 1994; Martin & Leary, 2001;
Martin, Leary, & O'Brien, 2001). The present study investigated the role of selfpresentation
on adolescent health-risk behaviours. Specifically, this study examined the
prevalence of adolescent identified health-risk behaviours rooted in self-presentational
motives in youths aged 13-18 years. The current study also identified the specific images
associated with these behaviours desired by youth, and the targets of these behaviours.
Also, the relationship between these behaviours, and several trait measures (social
physique anxiety, public-self consciousness, fear of negative evaluations, selfpresentational
efficacy) of self-presentation were examined. Finally, the gender
differences in health risk behaviours and self-presentational concerns were examined.
Participants in the present study were 96 adolescent students, 34 male and 62
female, recruited from various private schools across Southern Ontario. Students ranged
in age from 13 to 18 years for both males (M age = 15.81 years, SD = 1.49) and females
(M age = 14.89 years, SD = 1.17) and ranged from grades 8 through 13. Results of the
current study suggested that Canadian adolescents between the ages of 13 and 18 years
participated in health risk behaviours for self-presentational purposes. Drinking alcohol,
skipping school, and performing stunts and dares were identified as the most common
health risk behaviours performed for self-presentational purposes by both males and
females. Appearing fun and cool were the most commonly reported desired images while
appearing brave and mature were the least reported. The most desired target group cited
was same sex friends, followed by other sex friends. Trait measures of self-presentational
concerns identified females as being higher in public self-consciousness, and social
physique anxiety than males. Males were found to be higher in self-presentational
efficacy than females. The total number of health risk behaviours was predicted by selfpresentational
efficacy and social physique anxiety for males, and social physique anxiety
for females.
Findings of the current study suggest that Canadian adolescents' health risk
behaviours are rooted, in part, in self-presentational motives. Thus far, an educational
approach to health interventions has been favoured and/or adopted by teachers, health
promoters, and educators (Jessor, 1992). Implications of the current study suggest that
although educational interventions are beneficial in presenting the associated risks with
certain activities and/or behaviours, one reason this type of approach may be ineffective
in changing adolescent behaviour over the long run is that it does not address the strong
and prominent influences of interpersonal motives on health damaging behaviour. It is
evident that social acceptance and public image are of importance to adolescents, and the
desire to make the "right" impression and to achieve peer approval and acceptance often
override health and safety concerns (Jessor, 1992). Thus, a self-presentational approach
focusing on changing the images associated with the behaviours may be more successful
at deterring adolescent health risk behaviours.

The study centers on the power of Right-Wing Authoritarianism (RWA) and Social
Dominance Orientation (SDO) as predictors of prejudice against stereotypical and nonstereotypical
homosexuals under the threat of death and the threat of uncertainty.
Right-wing authoritarianism (RWA) is an individual difference variable that
measures the tendency for individuals to unquestionably follow those perceived to be
authorities. Social Dominance Orientation (SDO) is an individual difference variable that
measures the degree to which an individual prefers inequality among social groups. The
RWA and SDO Scales are considered to be two of the strongest predictors of prejudice, such
as prejudice against homosexuals. The study focuses on the unique predictive power of these
two variables in predicting prejudice against homosexuals.
The study also examines the role of situational threat in prejudice, specifically the
threat of death (mortality salience) and the threat of uncertainty (uncertainty salience).
Competing predictions from theories involving the threat of death (Terror Management
Theory) and the threat of uncertainty (Uncertainty Management Theory) are also tested. The
preference for expected information in the form of stereotypes concerning male homosexuals
(that is, a stereotypical or non-stereotypical homosexual) were tested.
The difference between the predictive power ofRWA and SDO was examined by
measuring how these variables predict liking of a stereotypical or non-stereotypical
homosexual under the threat of death, the threat of uncertainty, or a control condition. Along
with completing a measure for RWA and a measure for SDO, participants were asked to
think of their own death, of their being uncertain or about watching television then were
asked to read about a week in the life of either a stereotypical or non-stereotypical male
homosexual. Participants were then asked to evaluate the individual and his essay.
Based on the participants' evaluations, results from 180 heterosexual university
students show that RWA and SDO are strong predictors for disliking of a stereotypical
homosexual under the threat of uncertainty and disliking of a non-stereotypical homosexual
under the threat of death. Furthermore, however, results show that RWA is a particularly
strong predictor of disliking of a stereotypical homosexual under the threat of uncertainty,
whereas SDO is an exceptionally strong predictor of disliking of the non-stereotypical
homosexual under the threat of death. This further adds to the notion that RWA and SDO are
indeed unique predictors of prejudice. Implications are also explored, including the fact that
the study simuhaneously examined the role of individual difference variables and situational
threat variables, as well as exploratory analysis on Dominating Authoritarians.

The oscillation of neuronal circuits reflected in the EEG gamma frequency may be
fundamental to the perceptual process referred to as binding (the integration of various thoughts
and perceptions into a coherent picture). The aim of our study was to expand our knowledge of
the developmental course ofEEG gamma in the auditory modality.
2
We investigated EEG 40 Hz gamma band responses (35.2 to 43.0 Hz) using an auditory
novelty oddball paradigm alone and with a visual-number-series distracter task in 208
participants as a function of age (7 years to adult) at 9 sites across the sagital and lateral axes (F3,
Fz, F4, C3, Cz, C4, P3, Pz, P4). Gamma responses were operationally defined as change in
power or a change in phase synchrony level from baseline within two time windows. The evoked
gamma response was defined as a significant change from baseline occurring between 0 to 150
ms after stimulus onset; the induced gamma response was measured from 250 to 750 ms after
stimulus onset.
A significant evoked gamma band response was found when measuring changes in both
power and phase synchrony. The increase in both measures was maximal at frontal regions.
Decreases in both measures were found when participants were distracted by a secondary task.
For neither measure were developmental effects noted. However, evoked gamma power was
significantly enhanced with the presentation of a novel stimulus, especially at the right frontal
site (F4); frontal evoked gamma phase synchrony also showed enhancement for novel stimuli but
only for our two oldest age groups (16-18 year olds and adults).
Induced gamma band responses also varied with task-dependent cognitive stimulus
properties. In the induced gamma power response in all age groups, target stimuli generated the highest power values at the parietal region, while the novel stimuli were always below baseline.
Target stimuli increased induced synchrony in all regions for all participants, but the novel
stimulus selectively affected participants dependent on their age and gender. Adult participants,
for example, exhibited a reduction in gamma power, but an increase in synchrony to the novel
stimulus within the same region. Induced gamma synchrony was more sensitive to the gender of
the participant than was induced gamma power. While induced gamma power produced little
effects of age, gamma synchrony did have age effects.
These results confirm that the perceptual process which regulates gamma power is
distinct from that which governs the synchronization for neuronal firing, and both gamma power
and synchrony are important factors to be considered for the "binding" hypothesis. However,
there is surprisingly little effect of age on the absolute levels of or distribution of EEG gamma in
the age range investigated.

Memory Mixed with Desire: A preliminary study of Philosophy and Literature in
the works of Friedrich Nietzsche and Milan Kundera
Robert Spinelli
Brock University, Department of Philosophy
This thesis studies intertextuality in the works of Friedrich Nietzsche and Milan
Kundera through the primary themes of memory and forgetting. The thesis starts
with two introductory chapters that delineate memory according to Nietzsche
and Kundera respectively. From here, I move into a discussion of Nietzsche's
Ubermensch as an example of the type of forgetting that Nietzsche sees as a cure
for the overabundance of memory that has led to Christian morality. Next, I
explore the Kunderan concept of kitsch as the polar opposite of what Nietzsche
has sought in his philosophy, finishing the chapter by tying the two thinkers
together in a Kunderan critique of Nietzsche. The thesis ends with a chapter
devoted to the Eternal Return beginning with an exegesis of Nietzsche's idea and
ending with a similar exegesis of Kundera's treatment of this thought. What I
suggest in this chapter is that the Eternal Return might itself be a form of kitsch
even in its attempt to revalue existence.

This study applies a Marxist theoretical paradigm to examine the working conditions of
greenhouse workers in the Niagara Region, and the range of factors that bear upon the formation
of their class-consciousness. The Niagara greenhouse industry represents one of the most
developed horticultural regions in Canada and plays a prominent role in the local economy. The
industry generates substantial revenues and employs a significant number of people, yet the
greenhouse workers are paid one of the lowest rates in the region. Being classified as agricultural
workers, the greenhouse employees are exempted from many provisions of federal and
provincial labour regulations. Under the current provincial statutes, agricultural workers in
Ontario are denied the right to organize and bargain collectively. Except for a few technical and
managerial positions, the greenhouse industry employs mostly low-skilled workers who are
subjected to poor working conditions that stem from the employer's attempts to adapt to larger
structural imperatives of the capitalist economy. While subjected to these poor working
conditions, the greenhouse workers are also affected by objectively alienated social relations and
by ruling class ideological domination and hegemony. These two sets of factors arise from the
inherent conflict of interests between wage-labour and capital but also militate against the
development of class-consciousness.
Semi-structured interviews were conducted with 12 greenhouse workers to examine the
role played by their material circumstances in the formulation of their social and political views
as well as the extent to which they are aware of their class location and class interests. The
hegemonic notions of 'common sense' acted as impediments to formation of classconsciousness.
The greenhouse workers have virtually no opportunities to access alternative
perspectives that would address the issues associated with exploitation in production and offer
solutions leading to 'social justice'. Fonnidable challenges confront any organized political body
seeking to improve the conditions of the working people.

With the recent growth in cultural complexity, many organizations are faced with
increasingly diverse employee pools. Gaining a greater understanding of the values that
employees possess is the first step in effectively satisfying their needs and achieving a
more productive workforce (lung & Avolio, 2000). Values playa significant role in
influencing individual behaviours. It is therefore necessary to assess the qualities of
employee value systems and directly link them to the values of the organization. The
importance of values and value congruence has been emphasized by many organizational
behaviour researchers (cf. Adkins & Caldwell, 2004; Erdogan, Kraimer, & Liden, 2004;
Jung & Avolio, 2000; Rokeach, 1973); however the emphasis on value studies remains
fairly stagnant within the sport industry (Amis, Slack, & Hinings, 2002). In order to
examine the realities that were constructed by the participants in this study a holistic view
of the impact of values within a specific sport organization were provided. The purpose
of this case study was to examine organizational and employee values to understand the
effects of values and value congruence on employee behaviours within the context of a
large Canadian sport organization.
A mUltiple methods case study approach was adopted in order to fully serve the
purpose and provide a comprehensive view of the organization being examined.
Document analysis, observations, surveys, as well as semi-structured interviews were
conducted. The process allowed for triangulation and confirmability of the findings. Each
method functioned to create an overarching understanding of the values and value
congruence within this organization.
The analysis of the findings was divided into qualitative and quantitative sections.
The qualitative documents were analyzed twice, once manually by the researcher and
once via AtIas.ti Version 4 (1998). The a priori and emergent coding that took place was
based on triangulating the findings and uncovering common themes throughout the data.
The Rokeach Value Survey (1973) that was incorporated into the survey design of the
study was analyzed using descriptive statistics, as well as Mann-Whitney U, and Kruskal
Wallis formulas. These were deemed appropriate for analysis given the non-parametric
nature of the survey instrument (Kinnear & Gray, 2004). The quantitative survey served
to help define the values and value congruence that was then holistically examined
through the qualitative interviews, document analyses, and observations.
The results of the study indicated incongruent value levels between employees and
those stated or perceived as the organization's values. Each finding demonstrated that
varying levels of congruence may have diverse affects on individual behaviours. These
behaviours range from production levels to interactions with fellow employees to
turnover.
In addition to the findings pertaining to the research questions, a number of other
key issues were uncovered regarding departmentalization, communication, and board
relations. Each has contributed to a greater understanding of the organization and has
created direction for further research within this area of study.

The objectives of the present study were to explore three components of organizational
commitment (affective [AC], normative [NC] and continuance [CC] commitment; Allen
& Meyer, 1991), perceived relatedness (Oeci & Ryan, 1985; 2002), and behavioural
intention (Ajzen, 2002) within the context of volunteer track and field officiating. The
objectives were examined in a 2-phase study. Ouring phase 1, experts (N = 10) with
domain familiarity assessed the item content relevance and representation of modified
organizational commitment (OC; Meyer, Allen & Smith, 1993) and perceived relatedness
(La Guardia, Oeci, Ryan & Couchman, 2000) items. Fourteen of 26 (p < .05) items were
relevant (Aiken's coefficient V) and NC (M = 3.88, SO = .64), CC (M = 3.63, SD = .52),
and relatedness (M = 4.00, SD = .93) items had mean item content-representation ratings
of either "good" or "very good" while AC (M = 2.50, SD = 0.58) was rated "fair".
Participants in phase 2 (N = 80) responded to items measuring demographic variables,
perceptions of OC to Athletics Canada, perceived relatedness to other track and field
officials, and a measure of intention (yiu, Au & Tang, 2001) to continue officiating.
Internal consistency reliability estimates (Cronbach's (1951) coefficient alpha) were as
follows: (a) AC = .78, (b) CC = .85, (c) NC = .80 (d) perceived relatedness = .70 and, (e)
intention = .92 in the present sample. Results suggest that the track and field officials felt
only minimally committed to Athletics Canada (AC M = 3.90, SD = 1.23; NC M = 2.47,
SD = 1.25; CC M = 3.32; SD = 1.34) and that their relationships with other track and field
officials were strongly endorsed (M = 5.86, SD = 0.74). Bivariate correlations (Pearson
r) indicated that perceived relatedness to other track and field officials demonstrated the
strongest relationship with intention to continue officiating (r = .346, p < .05), while
dimensions of OC were not significantly related to intention (all p's > .05). Together
perceived relatedness (j3 = .339, p = .004), affective commitment (j3 = -.1 53, p = .308),
normative commitment (j3 = -.024, p = .864) and continuance commitment (j3 = .186, P =
.287) contribute to the prediction of intention to continued officiating (K = .139). These
relationships remained unaffected by the inclusion of demographic (j3age = -.02; P years with
Athletics Canada = -.13; bothp's > .05) or alternative commitment (j3sport = -.19; P role =
.15; Pathletes = .20; all p' s > .05) considerations. Three open-ended questions elicited
qualitative responses regarding participants' reasons for officiating. Responses reflecting
initial reasons for officiating formed these higher order themes: convenience, helping
reasons, extension of role, and intrinsic reasons. Responses reflecting reasons for
continuing to officiate formed these higher order themes: track and field, to help, and
personal benefits. Responses reflecting changes that would influence continued
involvement were: political, organizational/structural, and personal. These results
corroborate the findings of previous investigations which state that the reasons
underpinning volunteer motivations change over time (Cuskelly et al., 2002). Overall,
the results of this study suggest that track and field officials feel minimal commitment to
the organization of Athletics Canada but a stronger bond with their fellow officials.
Moreover, the degree to which track and field officials feel meaningfully connected to
one another appears to exert a positive influence on their intentions to continue
officiating. As such, it is suggested that in order to promote continued involvement,
Athletics Canada increases its focus on fostering environments promoting positive
interactions among officials.

Physical inactivity poses a huge burden on Canada's health care system and is
detrimental to the health of Canadians (Katzmarzyk & Janssen, 2004). Walking is a
viable option for individuals to become physically active on a daily basis and is in fact
the most commonly reported leisure time physical activity. It has been associated with
many health benefits including weight loss/weight control, reduced risk of coronary
artery disease and diabetes, lowered blood pressure, and improved psychological wellbeing
(Brisson & Tudor-Locke, 2004). Specifically, individuals' stage of change, selfefficacy
and health related quality of life (HRQL) are three psychological constructs that
can be greatly improved with increased physical activity (Dishman, 1991; Penedo &
Dahn, 2005; Poag & McAuley, 1992). Public health physical activity recommendations
exist but many individuals find these difficult to meet due to overly busy lifestyles
(Public Health Agency of Canada, 2003). Pedometers are inexpensive devices that can
monitor individual bouts of walking so that the incorporation of physical activity into
one's daily life is more plausible. They are also excellent tools for motivation, goalsetting,
and immediate feedback (Brisson & Tudor-Locke, 2004). Since many people
spend a large proportion of their time at their places of employment, workplaces have
begun to be a common site for the development of physical activity interventions. These
programs have been growing in popUlarity and have shown numerous benefits for both
employees and employers (Voit, 2001).
The purpose of the current study was to implement and evaluate the use of a
pedometer-based physical activity intervention incorporating goal-setting and physical
activity logs in a workplace setting, and to examine the relationship between different
types of self-efficacy (task, barrier, and scheduling) and different phases of the
intervention. Twenty male participants from a local steel manufacturing plant who
exhibited health risk factors (e.g. hypertension, diabetes, etc.) were assigned to one of
two groups (group A or group B). All participants were asked to wear pedometers on
their waists, record their daily steps, set goals that were outlined on a step-tracking sheet
(detennined by their baseline number of steps), and keep track of their work days,
wakelbed time, sedentary time, and time spent doing other physical activity. Group A
began the intervention immediately following the baseline measures, whereas group B
continued with their regular routine for 4 weeks before beginning. Physiological
measures (height, weight, blood pressure, relative body fat, waist and hip circumference,
and body mass index) were taken and a battery of questionnaires that assessed barrier,
task and scheduling self-efficacy, HRQL, and stage of change administered at baseline,
week 5 (end of intervention for group A), week 9 (end of intervention for group B;
follow-up for group A) and week 13 (follow-up for both groups).
Results showed that this workplace physical activity intervention was successful
at increasing the participants' daily steps, that task self-efficacy is a significant predictor
of participants' exercise adherence during the initial stages of participation (intervention
phase), and that the participants felt that this intervention was effective. Finally, further
exploratory analyses showed that this intervention was effective for all participants, but
most valuable for participants most in need of improvement - that is, those who were
most sedentary prior to the intervention. This intervention is an inexpensive use of simple
and effective tools (e.g. pedometers), has the potential to attract a wide variety of
participants and become a pennanent part of any health promotion initiative.

Existing research on attraction to body features has suggested that men show general
preferences for women with lower waist-to-hip ratios (WHR), larger breasts, and slender
body weights. The present study intended to expand on this research by investigating
several individual difference factors and their potential contribution to variation in what
men find attractive in female body features. Two hundred and seventy-three men were
assessed for sex-role identity, 2D:4D digit ratios (a possible marker of prenatal exposure
to androgens, and thus masculinization), physical attractiveness, early sexual experiences
(as indices of early sexual conditioning), and early family attitudes toward body features,
as well as their current preferences for WHR, breast size, weight, and height in women.
For WHR, as predicted, physical attractiveness, early sexual experiences, and lower
(more masculine) right-hand 2D:4D ratios significantly predicted current preferences for
more feminine (lower) WHR. Early sexual experiences significantly predicted later
preferences for breast size; in addition, more masculine occupational preferences and
lower (more masculine) left-hand 2D:4D ratios predicted preferences for larger breasts.
Participants' height, education level, Unmitigated Agency (masculinity) scores, and early
sexual experiences significantly predicted current preferences for height. Finally, early
sexual experiences significantly predicted current preferences for weight. The results
suggest that variation in preferences for women's bodily features can be uniquely
accounted for by a number of individual difference factors. Strengths and weaknesses of
the study, along with implications for future research, are discussed.

One hundred and five primarily Caucasian undergraduate couples were tested to
study the phenomenon of attitude alignment, or the way in which individuals change their
opinions to achieve greater attitudinal congruence with their romantic partners, and the
hypotheses that relationship closeness, affect, attachment, social desirability, and
centrality are each related to attitude alignment for individuals in close couples. The
couples filled out an attitude questionnaire consisting of 50 issues in which they were
asked to give their attitude on a scale from 1 to 9 as well as to rate the centrality, or
importance, of that issue on a scale from 1 to 9. Before discussing four of these issues
with each other - 2 were more central to the man and less central, or peripheral, to the
woman, whereas the other 2 were central to the woman and peripheral to the man - the
individuals completed established measures of relationship closeness, affect, attachment,
and social desirability. The couples then filled out the identical attitudes questionnaire
again, and their answers on the four discussion issues were compared to their prediscussion
answers to determine whether attitude alignment had occurred. There were
two experimental groups: a social desirability group, where the couples were told it was
natural and normal to disagree with their partners, and a control group. Results indicated
that attitude alignment did significantly occur across all couples, but most other variables
- including centrality, relationship closeness, and affect - did not predict attitude
alignment behaviour. As well, the social desirability experimental groups did not
significantly differ on attitude alignment behaviours, but higher scores on the social
desirability scale, specifically self-deception, significantly predicted higher attitude
alignment scores across all couples. Large differences between individuals' frequency.

Previous researchers have found that learners do not benefit fi-om using the Internet when
domain knowledge is low. The purpose of the current study was to investigate possible
methods to compensate for low domain knowledge. Specifically, the presence of notes,
more time to search the Internet, and high levels of motivation to use the Internet were
examined as possible compensating factors. Sixty Political Science and Kinesiology
undergraduate students were randomly assigned to one of three conditions. Students
searched the Internet for an hour prior to vmting an essay with notes present, searched the
Internet for an hour prior to writing an essay without notes present, or did not search the
Internet prior to completing an essay. Each participant completed the same two essays,
one corresponding to a high knowledge domain and another corresponding to a low
knowledge domain. First, the presence of notes did not significantly improve essay scores
in comparison to the absence of notes. Second, learners did benefit fi-om using the
Internet for 1 hour in comparison to their peers who were not exposed to the Internet,
regardless of level of domain knowledge. Third, high levels of motivation did not affect
essay performance. A discussion of why time may have compensated for low domain
knowledge while notes and motivation did not is included. In addition, methods that may
compensate for low domain knowledge when time is restricted are suggested.

The purpose ofthis study was to investigate the emotion assumptions underlying just-world
theory. This theory proposes that people have a need to believe in a just world - a world where
people get what they deserve. The first emotion assumption is that people, therefore, find
injustices (Le., undeserved outcomes) threatening and thus emotionally arousing. Second, it is
this arousal that is assumed to drive subsequent strategies for maintaining the belief in a just
world. One strategy an individual may use to maintain this belief is derogating victims of
injustice, or seeing their character in a more negative light. To test these two assumptions, 102
participants viewed a video depicting either a victim who presumably presented a high threat to
people's belief in ajust world (she was innocent and, therefore, undeserving of her fate) or low
threat (she was not innocent and, therefore, more deserving of her fate) while their heart rate and
EDA was measured. Half of the participants were then given the opportunity to help the victim
whereas the other half were not given this opportunity. The manipulations were followed by
both explicit and indirect measures of evaluations ofthe victim as well as self-report measures of
affect experienced while watching the victim video, and an individual difference scale assessing
the strength of participants' just-world beliefs (as well as other measures that were part ofa
larger study). Results indicated that participants did report feeling more threatened by the
innocent victim. Although there was some evidence of victim derogation on the implicit
measure of victim evaluation, there was no evidence that emotional arousal drove the negative
evaluations of the victim who could not be helped. Some interaction effects with individual
differences in just-world beliefs did occur, but these were not entirely consistent with the
rationale behind the individual difference scales. These results provide only weak support for the first emotion assumption ofjust-world theory. Implications of these findings as well as
limitations of the study and future directions concerning just-world theory are discussed.

This thesis examines the processes through which identity is acquired and the
processes that Hollywood :films employ to facilitate audience identification in order to
determine the extent to which individuality is possible within postmodem society.
Opposing views of identity formation are considered: on the one hand, that of the
Frankfurt School which envisions the mass audience controlled by the culture industry and
on the other, that of John Fiske which places control in the hands of the individual. The
thesis takes a mediating approach, conceding that while the mass media do provide and
influence identity formation, individuals can and do decode a variety of meanings from the
material made available to them in accordance with the text's use-value in relation to the
individual's circumstances. The analysis conducted in this thesis operates on the
assumption that audiences acquire identity components in exchange for paying to see a
particular film.
Reality Bites (Ben Stiller 1994) and Scream (Wes Craven 1996) are analyzed as
examples of mainstream 1990s films whose material circumstances encourage audience
identification and whose popularity suggest that audiences did indeed identify with them.
The Royal Tenenbaums (Wes Anderson 2001) is considered for its art film sensibilities and
is examined in order to determine to what extent this film can be considered a counter
example. The analysis consists of a combination of textual analysis and reception study in
an attempt to avoid the problems associated with each approach when employed alone.
My interpretation of the filmmakers' and marketers' messages will be compared with online
reviews posted by film viewers to determine how audiences received and made use of the
material available to them. Viewer-posted reviews, both unsolicited and unrestricted, as
found online, will be consulted and will represent a segment of the popular audience for
the three films to be analyzed.

This thesis attempts to clarify what Heidegger meant by the term "thinking"
(Denken), where this ^'meanr is submitted in the double sense: firstly, in the sense of
what Heidegger intended by the use and exposition of this term that we find in his lecture
series. Was Heisst Denken?, where Heidegger quickly makes it clear that this intention is
to actually bring thinking on the way, viz. making provision for the leap into thinking,
and where this intention was carried out with the employment of a specific guiding
phrase. In the second sense, it is an attempt at clarifying the meaning of the term. But this
is not to say that we are here simply out to see how Heidegger defines the word
'*thinking." It is in fact precisely within such definitive discourse that thought dies out. It
is not merely be a case of defining a word, because this enterprise would be just as
shallow as much as it would be unworkable. It is for this reason that Heidegger decided
to establish for himself the task, not merely of explaining thinking as something to be
beheld at a distance, but rather of bringing thinking underway by means of his lecture,
proclaiming that, "Only the leap into the river tells us what is swimming. The question
'What is called thinking?' can never be answered by proposing a definition of the concept
thinking, and then diligently explaining what is contained in that definition." (WCT, 21)
This being Heidegger's intention, in order to understand Heidegger in his treatment of the
term thinking, it is clear that we must also undergo an experience with thinking. It is in
this spirit that the present work was written so as to collaborate the two senses of what
Heidegger meant by "thinking."

Optimal challenge occurs when an individual perceives the challenge of the task to be
equaled or matched by his or her own skill level (Csikszentmihalyi, 1990). The purpose
of this study was to test the impact of the OPTIMAL model on physical education
students' motivation and perceptions of optimal challenge across four games categories
(i. e. target, batting/fielding, net/wall, invasion). Enjoyment, competence, student goal
orientation and activity level were examined in relation to the OPTIMAL model. A total
of 22 (17 M; 5 F) students and their parents provided informed consent to take part in the
study and were taught four OPTIMAL lessons and four non-OPTIMAL lessons ranging
across the four different games categories by their own teacher. All students completed
the Task and Ego in Sport Questionnaire (TEOSQ; Duda & Whitehead, 1998), the
Intrinsic Motivation Inventory (IMI; McAuley, Duncan, & Tanmien, 1987) and the
Children's Perception of Optimal Challenge Instrument (CPOCI; Mandigo, 2001).
Sixteen students (two each lesson) were observed by using the System for Observing
Fitness Instruction Time tool (SOFTT; McKenzie, 2002). As well, they participated in a
structured interview which took place after each lesson was completed. Quantitative
results concluded that no overall significant difference was found in motivational
outcomes when comparing OPTIMAL and non-OPTIMAL lessons. However, when the
lessons were broken down into games categories, significant differences emerged. Levels
of perceived competence were found to be higher in non-OPTIMAL batting/fielding
lessons compared to OPTIMAL lessons, whereas levels of enjoyment and perceived
competence were found to be higher in OPTIMAL invasion lessons in comparison to
non-OPTIMAL invasion lessons. Qualitative results revealed significance in feehngs of
skill/challenge balance, enjoyment and competence in the OPTIMAL lessons. Moreover,
a significance of practically twice the active movement time percentage was found in
OPTIMAL lessons in comparison to non-OPTIMAL lessons.

This study examined the effect of expHcitly instructing students to use a repertoire
of reading comprehension strategies. Specifically, this study examined whether
providing students with a "predictive story-frame" which combined the use of prediction
and summarization strategies improved their reading comprehension relative to providing
students with generic instruction on prediction and summarization. Results were
examined in terms of instructional condition and reading ability.
Students from 2 grade 4 classes participated in this study. The reading component
of the Canadian Achievement Tests, Second Edition (CAT/2) was used to identify
students as either "average or above average" or "below average" readers. Students
received either strategic predication and summarization instruction (story-frame) or
generic prediction and summarization instruction (notepad). Students were provided with
new but comparable stories for each session. For both groups, the researcher modelled
the strategic tools and provided guided practice, independent practice, and independent
reading sessions.
Comprehension was measured with an immediate and 1-week delayed
comprehension test for each of the 4 stories, hi addition, students participated in a 1-
week delayed interview, where they were asked to retell the story and to answer
questions about the central elements (character, setting, problem, solution, beginning,
middle, and ending events) of each story.
There were significant differences, with medium to large effect sizes, in
comprehension and recall scores as a fimction of both instructional condition and reading
ability. Students in the story-frame condition outperformed students in the notepad condition, and average to above average readers performed better than below average
readers. Students in the story-frame condition outperformed students in the notepad
condition on the comprehension tests and on the oral retellings when teacher modelling
and guidance were present. In the cued recall sessions, students in the story-frame
instructional condition recalled more correct information and generated fewer errors than
students in the notepad condition. Average to above average readers performed better
than below average readers across comprehension and retelling measures. The majority
of students in both instructional conditions reported that they would use their strategic
tool again.

Although alcohol problems and alcohol consumption are related, consumption does not
fully account for differences in vulnerability to alcohol problems. Therefore, other factors
should account for these differences. Based on previous research, it was hypothesized that risky
drinking behaviours, illicit and prescription drug use, affect and sex differences would account
for differences in vulnerability to alcohol problems while statistically controlling for overall
alcohol consumption. Four models were developed that were intended to test the predictive
ability of these factors, three of which tested the predictor sets separately and a fourth which
tested them in a combined model. In addition, two distinct criterion variables were regressed on
the predictors. One was a measure of the frequency that participants experienced negative
consequences that they attributed to their drinking and the other was a measure of the extent to
which participants perceived themselves to be problem drinkers. Each of the models was tested
on four samples from different populations, including fIrst year university students, university
students in their graduating year, a clinical sample of people in treatment for addiction, and a
community sample of young adults randomly selected from the general population. Overall,
support was found for each of the models and each of the predictors in accounting for differences
in vulnerability to alcohol problems. In particular, the frequency with which people become
intoxicated, frequency of illicit drug use and high levels of negative affect were strong and
consistent predictors of vulnerability to alcohol problems across samples and criterion variables.
With the exception of the clinical sample, the combined models predicted vulnerability to
negative consequences better than vulnerability to problem drinker status. Among the clinical
and community samples the combined model predicted problem drinker status better than in the
student samples.

This thesis takes seriously the proposition that existentialism is a lived philosophy. While Descartes'
proof for the existence of God initially sparked my interest in philosophy, the insights of existentialism
have allowed me to appropriate philosophy as a way of life. I apply the insights of Kierkegaard's writings
to my spiritual and philosophy development. Philosophy is personal, and Kierkegaard's writings deal with
the development of the person in his aesthetic, ethical and religious dimensions. Philosophy is a struggle,
and this thesis, reveals the existential struggle of the individual in despair.
The thesis argues that authentic faith actually entails faith. The existential believer has this faith whereas
the religious believer does not. The subjectively reflective existential believer recognizes that a leap of
faith is needed; anything else, is just historical, speculative knowledge. The existential believer or, the
Knight of Faith, realizes that a leap of faith is needed to become open in inwardness to receive the
condition to understand the paradoxes that faith presents. I will present Kierkegaard's "Analogy of a
House" which is in essence, the backbone of his philosophy. I will discuss the challenge of moving from
one floor to the next. More specifically, I will discuss the anxiety that is felt in the very moment of the
transition from the first floor to the second floor. I will outline eight paradoxes that must me resolved in
order for the individual to continue on his journey to the top floor of the house.
I will argue that Kierkegaard's example of Abraham as a Knight of Faith is incorrect, that Abraham was
in fact not a Knight of Faith. I will also argue that we should find our own exemplars in our own lives by
looking for Knight of Faith traits in people we know and then trying to emulate those people. I will also
discuss Unamuno's "paradoxical faith" and argue that this kind of faith is a strong alternative to those
who find that Kierkegaard's existential faith is not a possibility.

Perovskite manganite compounds, Lai-xDxMnOs (D-divalent alkaline earth
Ca, Sr or Ba), whose electrical and magnetic properties were first investigated
nearly a half century ago, have attracted a great deal of attention due
to their rich phase diagram.
From the point of view of designing a future application, the strong pressure
dependence of the resistivity and the accompanying effects in thin films have
potential for application in pressure sensing and electronic devices.
In this study we report our experimental investigations of pressure dependence

Conidia of the insect pathogenic fungus, Metarhizium anisopliae play an important role
in pathogenicity because they are the infective propagules that adhere to the surface of
the insect, then germinate and give rise to hyphal penetration of the insect cuticle.
Conidia are produced in the final stages of insect infection as the mycelia emerge from
the insect cadaver. The genes associated with conidiation have not yet been studied in
this fiingus. hi this study we used the PCR-based technique, suppression subtractive
hybridization (SSH) to selectively amplify conidial-associated genes in M. anisopliae.
We then identified the presence of these differentially expressed genes using the National
Center for Biotechnology Information database. One of the transcripts encoded an
extracellular subtilisin-like protease, Prl, which plays a fundamental role in cuticular
protein degradation. Analysis of the patterns of gene expression of the transcripts using
RT-PCR indicated that conidial-associated cDNAs are expressed during the development
of the mature conidium. RT-PCR analysis was also performed to examine in vivo
expression of Prl during infection of waxworm larvae {Galleria mellonelld). Results
showed expression of Prl as mycelia emerge and produce conidia on the surface of the
cadaver. It is well documented that Prl is produced during the initial stages of
transcuticular penetration by M. anisopliae. We suggest that upregulation of Prl is part
of the mechanism by which reverse (from inside to the outside of the host) transcuticular
penetration of the insect cuticle allows subsequent conidiation on the cadaver.

SUMMARY
Background: Age related declines in lower extremity strength have been associated with
impaired mobility and changes in gait patterns, which increase the likelihood of falls.
Since community dwelling adults encounter a wide range of locomotor challenges
including uneven and obstmcted walking surfaces, we examined the effect of a strength
11
and balance exercise program on obstructed walking in postmenopausal women.
Objectives: This study examined the effect of a weighted-vest strength and balance
exercise program on adaptations of the stance leg during obstacle walking in
postmenopausal women. Methods: Eighteen women aged 44-62 years who had not
engaged in regular resistance training for the past year were recruited from the St.
Catharines community to participate in this study. Eleven women volunteered for an
aerobic (walking), strength, and balance training program 3 times per week for 12 weeks
while 7 women volunteered as controls. Measurements included: force platform dynamic
balance measure of the center of pressure (COP) and ground reaction forces (GRFs) in the
stance leg while going over obstacles of different heights (0,5, 10,25 and 30 cm); and
isokinetic strength measures of knee and ankle extension and flexion. Results: Of the 18
women, who began the trial, 16 completed it. The EX group showed a significant increase
of 40% in ankle plantar flexion strength (P < 0.05). However, no improvements in
measures of COP or GRFs were observed for either group. Failure to detect any changes in
measures of dynamic balance may be due to small sample size. Conclusions:
Postmenopausal women experience significant improvements in ankle strength with 12
weeks of a weighted-vest balance and strength training program, however, these changes
do not seem to be associated with any improvement in measures of dynamic balance.

This study explores the tension that has emerged around the rise of home
schooling in a faith-community strongly committed to establishing and maintaining day
schools in the tradition of John Calvin. It aims to identify and understand factors that
contributed to this tension and to find ways to bridge, diffuse, reduce, or eliminate it. In
line with Calvin, personal convictions, and the nature of the community, the study takes a
Christian epistemological and axiological stance. Its premise is that the integrity of the
commvmity is more important than the manner in which its children are taught.
The study reviews relevant literature and several interviews. It considers both
secular and Christian literature to understand communities, community breakdown, and
community restoration. It also examines literature about the significance of home, school,
and community relationships; the attraction of Reformed day schools; and the appeal of
home schooling. Interviews were conducted with 4 home schooling couples and 2 focus
groups. One focus group included local school representatives, and the other home
schoolers and school representatives from an area with reputedly less tension on the issue.
Interviews were designed for participants to give their perspectives on reasons for home
schooling, the existing tension, and ways to resolve the issues.
The study identifies the rise of home schooling in this particular context as the
initial issue and the community's deficiency to properly deal with it as the chief cause for
the rising tensions. However, I argue that, within the norms the community firmly
believes in, home schooling need not jeopardize its integrity. I call for personal, social,
and spiritual renewal to restore the covenant community in gratitude to God.

This is a study of one participant's reflective practice as she worked to develop
online communities in a face-to-face science course. Her process of reflective practice
was examined in order to address factors that influenced her learning path, and the
benefits and challenges of collaborative action research. These research goals were
pursued using a collaborative action research methodology, initially chosen for its close
match with Schon's (1983) model of reflective practice. The participant's learning fit
vnth Mezirow's (1991) model of transformative learning. She began with beliefs that
matched her goals, and she demonstrated significant learning in three areas. First, she
demonstrated instrumental learning around the constraints of workload and time, and
achieving online learning community indicators. Second, she demonstrated
communicative learning that helped her to see her own needs for feedback and
communication more clearly, and how other process partners had been a support to her.
Third, her emancipatory learning saw her revisiting and questioning her goals. It was
through the reflective conversation during the planned meetings and the researcher's reframing
and interrogation of that reflection that the participant was able to clarify and
extend her thinking, and in so doing, critically reflect on her practice as she worked to
develop online learning communities. In this way, the collaborative action research
methodology was an embodiment of co-constructivism through collaborative reflective
practice. Schon's (1983) model of reflective practice positions a lone practitioners
moving through cycles ofplan-act-observe-reflect. The results fi"om this study suggest
that collaboration is an important piece of the reflective practice model.

A qualitative study was conducted to detennine 5 nursing educators'
perceptions about the online application of a problem-based learning strategy in
undergraduate nursing education. The question asked in the study was: Can the
essential elements of face-to-face problem-based learning be supported in an online
format? The data for this study came from 2 individual tape-recorded interviews
with each of the 5 participants over a 3-month period and from a researchjournaI.
The educators felt that student-centered learning and critical thinking could be
supported within an online format. However, they noted that challenges could exist
in terms of developing tutor roles, fostering student self-direction, facilitating group
process and connections, and incorporating a nursing philosophy of online learning.
The importance of tailoring an online problem-based learning course to reflect
educators' philosophies and values in nursing emerged as an important theme from
the interview responses. Overall, the participants suggested that an ideal
environment would blend both face-to-face and online elements and that fewer
elements would be offered in the first 2 years of the nursing program. They
described a hybrid model of problem-based learning in which the online component
could be used to support face-to-face sessions.

The purpose of this exploratory investigation was to provide a more precise
understanding and basis from which to assess the potential role of the precautionary
principle in tourism. The precautionary principle, analogous to the ideal of sustainable
development, is a future-focused planning and regulatory mechanism that emphasizes
pro-action and recognizes the limitations of contemporary scientific methods. A total of
100 respondents (80 tourism academics, 20 regional government tourism officials) from
Canada, United States, United Kingdom, Australia and New Zealand completed the webbased
survey between May and June 2003. Respondents reported their understanding of
the precautionary principle, rated stakeholder involvement and education strategies,
assessed potential barriers in implementation, and appraised steps of a proposed
fi-amework for implementation. Due to low sub sample numbers, measures of central
tendency were primarily used to compare groups, while inferential statistics were applied
when warranted. Results indicated that most respondents (79%) felt the principle could
be a guiding principle for tourism, while local and regional government entities were
reported to have the most power in the implementation process. Findings suggested close
links between the precautionary principle and sustainability, as concern for future
generations was the most critical element of the principle for tourism. Overall, tourism
academics were more supportive of the precautionary principle in tourism than were
regional government tourism officials. Only minor variation was found in responses
among regional groups across all variables. This study established basic ground for
understanding the precautionary principle in tourism and has been effective in
formulating more precise questions for future research.

Self-presentation is the process by which individuals attempt to monitor and
control how others perceive and evaluate them (Leary, 1992; Leary & Kowalski, 1990).
Self-presentational concerns have been shown to influence a number of exercise-related
behaviours, cognitions, and affective responses to exercise (e.g., social anxiety). Social
anxiety occurs when an individual wants to create a specific impression on others, but is
unsure (s)he will be successful (Leary & Kowalski, 1995). Social physique anxiety (SPA)
is a specific form of social anxiety related the evaluation of one's body (Hart, Leary, &
Rejeski, 1989). Both social anxiety and SPA may act as deterrents to exercise (Lantz,
Hardy, & Ainsworth, 1997; Leary, 1992), so it is important to examine factors that may
influence social anxiety and SPA; one such factor is self-presentational efficacy (SPE).
SPE is one's confidence in successfully making desired impressions on others (Leary &
Atherton, 1986) and has been associated with social anxiety and SPA (Leary &
Kowalski, 1995; Gammage, Martin Ginis, & Hall, 2004).
Several aspects of the exercise environment, such as the presence of mirrors,
clothing, and the exercise leader or other participant characteristics, may be manipulated
to influence self-presentational concerns (e.g., Gammage, Martin Ginis et aI., 2004;
Martin & Fox, 2001; Martin Ginis, Prapavessis, & Haase, 2005). Given that the exercise
leader has been recognized as one of the most important influences in the group exercise
context (Franklin, 1988), it is important to further examine how the leader may impact
self-presentational concerns. The present study examined the impact of the exercise
leader's gender and physique salience (i.e., the extent to which the body was emphasized)
on SPE, state social anxiety (SSA), and state social physique anxiety (SPA-S) of women
in a live exercise class.
Eighty-seven college-aged female non- or infrequent exercisers (i.e., exercised 2
or fewer times per week) participated in a group exercise class led by one of four leaders:
a female whose physique was salient; a female whose physique was non-salient; a male
whose physique was salient; or a male whose physique was non-salient. Participants
completed measures of SPE, SSA, and SPA-S prior to and following completion of a 30-
minute group exercise class. In addition, a measure of social comparison to the exercise
leader and other participants with respect to attractiveness, skill, and fitness was
completed by participants following the exercise class.
A MANOV A was conducted to examine differences between groups on postexercise
variables. Results indicated that there were no significant differences between
groups on measures ofSPE, SSA, or SPA-S (allp's > .05). However, when all
participants were collapsed into one group, a MANOV A showed a significant time effect
(F(3, 81) = 19.45,p < .05, 1')2= .419). Follow-up ANOVAs indicated that post-exercise
SPE increased significantly, while SSA and SPA-S decreased significantly (SPE: F(I,
83) = 30.87,p < .001,1')2 = .27; SSA: F(I,83) = 11.09,p < .001, 1')2 = .12; SPA-S: F (1,83)
= 42.79,p < .001, 1')2 = .34). Further, results of a MANOVA revealed that participants
who believed they were less fit than other group members (i.e., made negative social
comparisons) reported significantly more post-exercise SSA and SP A-S than those who
believed they were more fit than the other participants (i.e., made positive comparisons;
SSA: F(2, 84) = 3.46, p < .05, 1')2 = .08; SPA-S: F(2, 84) = 5.69, p < .05, 1')2 = .12).
These results may indicate that successfully completing an exercise class may
serve as a source of SPE and lead to reduced social anxiety and SPA-S in this population.
Alternatively, characteristics of the exercise leader may be less important than
characteristics of the other participants. These results also suggest that the types of social
comparisons made may influence self-presentational concerns in this sample. Future
research should examine how the type of social comparison (i.e., negative or positive)
made to the other group members may either generate or reduce anxiety. Also, factors
that contribute to the types of social comparisons made with other exercisers should be
examined. Implications for practice and research are discussed.

To explore the idea of education to close the ingenuity gap I use
Thomas Homer-Dixon's work to define ingenuity. The notion that the
supply of ingenuity to solve our technical and social problems is not
keeping pace with the ingenuity required to solve those problems is
called the ingenuity gap. Man-made technological developments are
increasing the density, intensity, and pace of globalisation. People must
reorganise decision-making organisations and problem-solving methods
to pragmatically combat the growing ingenuity gap. John Dewey's work
illustrates the fundamental attitudes for the thinking and judgment
associated with educating for ingenuity. Howard Gardner's idea that
truth, beauty, and morality ought to form the core values and tenets of
the philosophy of educating for ingenuity is integral to this thesis. The
act of teaching facilitates the invitation to the communication necessary
to foster ingenuity. John Novak-discusses the five relationships of
educational leadership that enhance an environment of ingenuity. The
International Baccalaureate (IB) is an existing model of global education,
one that defines some of the school experiences and academic
development of core values of educating for ingenuity. Expanding upon
the structure of the IB and other research within this thesis, I speculate
upon what my school, where educating for ingenuity so as to close the
ingenuity gap is the goal, would be like.

In this thesis, I argue that the mutually productive relationship between women (as
gendered subjects) and cellular phone technology is one of control. Women use cellular
phones to organize, manage and otherwise control the multiplicity of tasks required of
them on a daily basis. At the same time, through using cell phones, women participate in
regimes of control including surveillance and persistent connection. I explore this
relationship at the level of everyday practice, and conclude by speculating about this
relationship at a wider level of social control and organization.
This argument emerges from the critical approach suggested by Slack and Wise (2005),
who argue that technology and culture are inseparable. They provide articulations and
assemblages as tools of analysis. I situate this analysis more broadly within Foucault's
(1991) work on govemmentality, in its modem form of societies of control (Deleuze,
1995b).

Objective. Physical activity is important for the health of all human beings.
Although it is important to develop good health promotion programs for children to
increase participation in physical activity, to date there appear to be no programs based
on what kids value beyond health and physical activity itself. This study proposed to
create a scale with strong content and face validity that could uncover what any given
population of children value in life regardless of their participation in physical activity
and that experts feel could be related to physical activity. These findings will allow the
development of targeted health promotion programs to increase children's participation in
regular physical activity.
Method In this study, a combination of qualitative and quantitative approaches
was used. Data were gathered from seven experts in the field, sixty-seven children in
grades three to five, five parents, and three teachers. From these data response groupings
were created and sent to four experts to be given single word names. The resulting nine
theme names were re-worked into "child-friendly" language. Four children were then
asked to discuss theme names to see if they liked and understood them. The next step
involved asking children and experts to rank order the nine themes, the children in
general and the experts in terms of relevance to physical activity. From these results,
possible versions of the scale were then created using the combined expert/children
rankings. Each version was examined for content validity. Two versions of a scale
resulted. These were sent to experts, parents, teachers and children in order to determine
which one they liked better and to suggest any foreseeable problems. Once this
information was collected, a beta (final prototype) version of the scale was created.
Results. Nine common theme names were created from the response groupings.
All four children agreed that they did understand and like each of the nine theme names.
Experts and teachers agreed that full coverage of the content had been achieved.
Children suggested a single wording change from "Being Accepted" to "Being Included".
Five themes were selected for inclusion. The beta version of the scale included 12 forced
choice statements, the first ten comparing all themes against one another followed by two
anchor statements.
Conclusion. At the outset it was recognized that it is essential to know what
children think is important in their lives in order to serve as potential benefits in the
development of effective physical activity promotion programs. This study developed a
scale which could be used to determine what a population of children feel is important in
order to focus health promotion programs for physical activity. The scale has strong face
and content validity.

Black flies are opportunistic sugar-feeders. They take sugar meals from
Homopteran honeydew secretions or plant nectars, depending on availability.
Homopteran honeydew secretions contain both simple and complex carbohydrates while
plant nectars contain primarily simple carbohydrates. In order to determine whether
honeydew secretions offer more energy than plant nectars to their insect visitors a study
of wild-caught black flies was undertaken in Algonquin Provincial Park, Canada during
the spring of 1 998 and 1 999. It was hypothesized that female black flies maintained on
honeydew sugars will survive longer, produce more eggs and have a greater parasite
vectoring potential than those maintained on artificial nectar or distilled water. Results
demonstrated that: (1) host-seeking female Prosimulimfuscum/mixtum and Simulium
venustum maintained on artificial honeydew did not survive longer than those maintained
on artificial nectar when fed ad libitum; (2) fiiUy engorged S. venustum and Simulium
rugglesi maintained on artificial honeydew did not produce more eggs than those
maintained on artificial nectar when fed ad libitum; and (3) S. rugglesi did not have a
greater vectoring potential of Leucocytozoon simondi when maintained on artificial
honeydew as opposed to artificial nectar when fed ad libitum. However, all flies
maintained on the two sugars (artificial honeydew and artificial nectar) survived longer,
produce more eggs and had greater vectoring potential than those maintained on distilled
water alone.

One of the various functions of proteins in biological systems is the transport of small
molecules, for this purpose proteins have naturally evolved special mechanisms to allow both
ligand binding and its subsequent release to a target site; a process fundamental to many
biological processes. Transport of Vitamin E (a-tocopherol), a lipid soluble antioxidant, to
membranes helps in the protection of polyunsaturated fatty acids against peroxidative damage.
In this research, the ligand binding characteristics of several members of the CRALTRIO
family of lipid binding proteins was examined; the recombinant human a-Tocopherol
Transfer Protein (a-TIP), Supernatant Protein Factor (SPF)ffocopherol Associated Protein
(TAP), Cellular Retinaldehyde Binding Protein (CRALBP) and the phosphatidylinositol transfer
protein from S. cerevisiae Sec 14p. Recombinant Sec 14p was expressed and purified from E. coli
for comparison of tocopherol binding to the two other recombinant proteins postulated to traffic
a-tocopherol.
Competitive binding assays using [3H]-a-tocopherol and Lipidex-l000 resin allowed
determination of the dissociation constants ~) of the CRAL-TRIO proteins for a-tocopherol
and - 20 hydrophobic ligands for evaluation of the possible biological relevance of the binding
interactions observed.
The KIs (nM) for RRR-a-tocopherol are: a-TIP: 25.0, Sec 14p: 373, CRALBP: 528 and
SPFffAP: 615. This indicates that all proteins recognize tocopherol but not with the same
affinity. Sec 14p bound its native ligand PI with a KI of381 whereas SPFffAP bound PI (216)
and y-tocopherol (268) similarly in contrast to the preferential binding ofRRR-a-tocopherol by
a-TIP.
Efforts to adequately represent biologically active SPFff AP involved investigation of
tocopherol binding for several different recombinant proteins derived from different constructs
and in the presence of different potential modulators (Ca+2, Mg+2, GTP and GDP); none of these
conditions enhanced or inhibited a-tocopherol binding to SPF. This work suggests that only aTTP
serves as the physiological mediator of a-tocopherol, yet structural homology between
proteins allows common recognition of similar ligand features.
In addition, several photo-affmity analogs of a-tocopherol were evaluated for their
potential utility in further elucidation of a-TTP function or identification of novel tocopherol
binding proteins.

The use of certain perfonnance enhancing substances and methods has been
defined as a major ethical breach by parties involved in the governance of highperfonnance
sport. As a result, elite athletes worldwide are subject to rules and
regulations set out in international and national anti-doping policies. Existing literature on
the development of policies such as the World Anti-Doping Code and The Canadian antiDoping
Program suggests a sport system in which athletes are rarely meaningfully
involved in policy development (Houlihan, 2004a). Additionally, it is suggested that this
lack of involvement is reflective of a similar lack of involvement in other areas of
governance concerning athletes' lives. The purpose ofthis thesis is to examine the history
and current state of athletes' involvement in the anti-doping policy process in Canada's
high-perfonnance sport system. It includes discussion and analysis of recently conducted
interviews with those involved in the policy process as well as an analysis of relevant
documents, including anti-doping policies. The findings demonstrate that Canadian
athletes have not been significantly involved in the creation of recently developed antidoping
policies and that a re-evaluation of current policies is necessary to more fully
recognize the reality of athletes' lives in Canada's high-perfonnance sport system and
their rights within that system.

Interpretation has been used in many tourism sectors as a technique in achieving
building hannony between resources and human needs. The objectives of this study are to
identify the types of the interpretive methods used, and to evaluate their effectiveness, in
marine parks. This study reviews the design principles of an effective interpretation for
marine wildlife tourism, and adopts Drams' five design principles (1997) into a
conceptual framework. Enjoyment increase, knowledge gain, attitude and intention
change, and behaviour modification were used as key indicators in the assessment of the
interpretive effectiveness of the Vancouver Aquarium (VA) and Marineland Canada (MC).
Since on-site research is unavailable, a virtual tour is created to represent the interpretive
experiences in the two study sites. Self-administered questionnaires are used to measure
responses. Through comparing responses to the questionnaires (pre-, post-virtual tours
and follow-up), this study found that interpretation increased enjoyment and added to
respondents' knowledge. Although the changes in attitudes and intentions are not
significant, the findings indicate that attitude and intention changes did occur as a result
of interpretation, but only to a limited extent. Overall results suggest that more techniques
should be added to enhance the effectiveness of the interpretation in marine parks or
self-guiding tours, and with careful design, virtual tours are the innovative interpretation
techniques for marine parks or informal educational facilities.

Discussions concerning the challenges of combining work and family are certainly not
new, and still actively continue. There is, however, a silence in the related literature
regarding a comprehensive description of integrating specifically university academic
~. work and family responsibilities. This silence is especially evident for men who are
parents as well as academics. With the participation of 4 key informants, this qualitative
research study gave voice to men and women who participate in the academic labour of a
Canadian university as professors, and as graduate students, along with the parenting
labour of at least 1 child under the age of7.
Methodology was developed to reveal in-depth perspectives regarding the work
practices employed by 4 key informants as they combined intellectual and child-care
responsibilities. Multiple data collection methods included journal reflections, day time
observation sessions, a focus group, and a final evaluation questionnaire. Using research
findings, together with information extrapolated from Three Models of the Family
(Eichler, 1997), this study also took steps toward developing a Proposed "Three Models
of the University," to offer explanation for the work practices of the key informants as
academics/parents, and also for future consideration in university policy formation.

This research illuminates the relationship between female
adolescents' self-concept and their experience of physical education.
This was accomplished through three stages of interviews and a Qsort.
The topics through which the research was categorized included
peer support, teachers as significant others, meaningful connections
to the body, and curriculum content. During stage one female physical
education specialists, curriculum coordinators, and adolescents were
interviewed to develop Q-items for the Q-sort. The second stage
Involved two groups of females between the ages of 12 and 14 years
who participated in the Q-sort. The final stage involved an insight
group that consisted of four Q-sort participants who interpreted the
highest ranking Q-items. Critical to this research was giving these
adolescents the opportunity to voice what was important to them.
The results of the research included descriptions of the
elements in physical education that were deemed most important by
female adolescent students. The topics of "peer support" and
"meaningful connections to the body" were ranked the highest. By
interpreting the rich insights of the discussion group, it was found that
peers were most influential to these young girls. Perceiving and
bestowing respect were imperative in this stage of their lives.

The present study explored the connections among adolescents' sense of self,
sexuality, and perceptions of risk. Such an exploration may help educators to further
understand why adolescents engage in risk-taking behaviours such as unprotected sex.
The study involved secondary analysis on the data collected from the Youth
Lifestyle Choices - Community University Research Alliance 2000 (YLC - CURA)
Youth Resilience Questionnaire (YRQ). Participants were 300 male and female students
in Grades 9, 1 1 and OAC. Data analyses involved both descriptive and inferential
statistics (correlational and multivariate analysis). Chi-square analyses were performed
on the open-ended self-description question. Separate analyses were conducted on
gender and age (grade levels).
Correlational analyses revealed that adolescents with a more positive sense of self
were more likely to perceive sexual involvement as a relatively high-risk behaviour.
Specifically, results found that male adolescents were less likely than females to perceive
sex to be risky. Results are discussed in relation to previous research in the area of selfcognitions
and risk-taking sexual behaviour. Results are also discussed in terms of
educational implications in that the current results may provide the beginnings of a
framework for more holistic sexual education programs.

A new synthetic pathway to analogues of the aglucones of naturally occurring
cyclic hydroxamic acids (2,4-dihydroxy-l,4-benzoxazin-3-ones) has been developed.
The new pathway involves the coupling of substituted nitrophenols wdth /-propyl-abromo-
O-methoxymethylglycolate. These materials were reductively cyclised to
reveal the hydroxamic acid functionality. Removal of the C-2 0-methoxymethyl
protecting group was achieved chemoselectively using boron trichloride. The
analogue 7-methoxy-2,4-dihydroxy-l,4-benzoxazin-3-one (DIMBOA) was assayed
with papain and a semilog plot of activity of papain in the presence of excess
DIMBOA was found to be linear. A single exponential equation was suggested as the
model for kinetic analysis. '^ Nuclear magnetic resonance (NMR) spectra of a
couple of hydroxamates were acquired as reference standards for future mechanistic
studies of these compounds as thiol protease inhibitors. A 10% '^-labeled sample
ofDIMBOA was also prepared for future mechanistic studies using NMR techniques.

Matings systems using signals for sexual communication have been studied
extensively and results commonly suggest that females use these signals for locating
males, species-identification, and mate choice. Although numerous mating systems
employ multiple signals, research has generally focused on long-range signals perhaps
due to their prominence and ease of study. This study focused on the short-range
acoustic courtship song of crickets. The results presented here suggest this signal is
under selection by female choice. Females mated preferentially with males having
shorter silences between the two types of ticks within the song. The length of these
silences (Gap 1) was correlated with male condition such that males having long
silences were significantly lower in mass with respect to body size when compared to
males having short silences. Both Gap 1 length and male condition were significantly
repeatable within males over time suggesting the possibility these traits have a genetic
basis. This study is the first empirical study to test female preferences within the natural
variation of the courtship song. It now appears, at least in crickets, that both the longand
short-range signals of a multi-signal mating system may contribute to male mating
success.

Abstract
This thesis seeks to answer a number of questions concerning
the deficit and debt in Canada. It focuses pri.arily on the
federal level of government but with SOBe discussion of provincial
governaent policy as well. In ~997, Canada's federal debt caae
close ro six hundred billion dollars - $594 billion or 74.4 % of
Gross Do.estic Product (GDP) to be exact. The purpose of this
theses is threefold: To find out why Canada accu.ulated such a
debt, to discover if there is a so-called debt crisis; and to
discover if it is possible to preserve Canada's national welfare
state given the financial restraints that have been adopted by both
federal and provincial governments.
Politicians are torn between economist' two contrasting views
regarding deficits: Neo-Keynesian and neo-conservative. The neoKeynesian
school focuses al1llOst exclusively on the short term
stability of the economy and tends to dismiss concerns regarding
the level of debt. Neo conservatives focus almost exclusively on
the perceived costs of growth in the national debt and are willing
to forego any stabilization benefits to ensure that the debt is
controlled. These polar view do have one thing in coa.on; both
confix-. that deficits influence govermaent policies. Both of these
econoBic theories will have far-reaching influences on the federal
gover1lJlJent's decision-making process. These economic theories will
be discussed throughout this thesis.

The biotransformation of water insoluble substrates by mammalian and
bacterial cells has been problematic, since these whole cell reactions are
primarily performed in an aqueous environment The implementation of a twophase
or encapsulated system has the advantages of providing a low water
system along with the physiological environment the cells require to sustain
themselves. Encapsulation of mammalian cells by formation of polyamide
capsules via interfacial polymerization illustrated that the cells could not survive
this type of encapsulation process. Biotransformation of the steroid
spironolactone [3] by human kidney carcinoma cells was performed in a
substrate-encapsulated system, yielding canrenone [4] in 70% yield.
Encapsulation of nitrile-metabolizing Rhodococcus rhodochrous cells using a
polyamide membrane yielded leaky capsules, but biotransformation of 2-(4-
chlorophenyl)-3-methylbutyronitrile (CPIN) [6] in a free cell system yielded
CPIN amide [7] in 40% yield and 94% ee. A two-phase biotransformation of
CPIN consisting of a 5:1 ratio of tris buffer, pH 7.2 to octane respectively, gave
CPIN acid [8] in 30% yield and 97% ee. It was concluded that Rhodococcus
rhodochrous ATCC 17895 contained a nonselective nitrile hydratase and a highly
selective amidase enzyme.

Although local grape growers view bird depredation as a significant economic issue, the
most recent research on the problem in the Niagara Peninsula is three decades old. Peer-reviewed
publications on the subject are rare, and researchers have struggled to develop bird-damage
assessment techniques useful for facilitating management programmes. I used a variation of
Stevenson and Virgo's (1971) visual estimation procedure to quantify spatial and temporal trends
in bird damage to grapes within single vineyard plots at two locations near St. Catharines, Ontario.
I present a novel approach to managing the rank-data from visual estimates, which is
unprecedented in its sensitivity to spatial trends in bird damage. I also review its valid use in
comparative statistical analysis.
Spatial trends in 3 out of 4 study plots confirmed a priori predictions about localisation in
bird damage based on optimal foraging from a central location (staging area). Damage to grape
clusters was: (1) greater near the edges of vineyard plots and decreased with distance towards the
center, (2) greater in areas adjacent to staging areas for birds, and (3) vertically stratified, with
upper-tier clusters sustaining more damage than lower-tier clusters.
From a management perspective, this predictive approach provides vineyard owners with
the ability to identify the portions of plots likely to be most susceptible to bird damage, and thus
the opportunity to focus deterrent measures in these areas. Other management considerations at
Henry of Pelham were: (1) wind damage to ice-wine Riesling and Vidal was much higher than
bird damage, (2) plastic netting with narrow mesh provided more effective protection agsiinst birds
than nylon netting with wider mesh, and (3) no trends in relative susceptibility of varietals by
colour (red vs green) were evident.

In this work, the magnetic field penetration depth for high-Tc cuprate superconductors
is calculated using a recent Interlayer Pair Tunneling (ILPT) model proposed by
Chakravarty, Sudb0, Anderson, and Strong [1] to explain high temperature superconductivity.
This model involves a "hopping" of Cooper pairs between layers of the unit
cell which acts to amplify the pairing mechanism within the planes themselves. Recent
work has shown that this model can account reasonably well for the isotope effect and
the dependence of Tc on nonmagnetic in-plane impurities [2] , as well as the Knight shift
curves [3] and the presence of a magnetic peak in the neutron scattering intensity [4]. In
the latter case, Yin et al. emphasize that the pair tunneling must be the dominant pairing
mechanism in the high-Tc cuprates in order to capture the features found in experiments.
The goal of this work is to determine whether or not the ILPT model can account for
the experimental observations of the magnetic field penetration depth in YBa2Cu307_a7.
Calculations are performed in the weak and strong coupling limits, and the efi"ects of both
small and large strengths of interlayer pair tunneling are investigated. Furthermore, as a
follow up to the penetration depth calculations, both the neutron scattering intensity and
the Knight shift are calculated within the ILPT formalism. The aim is to determine if the
ILPT model can yield results consistent with experiments performed for these properties.
The results for all three thermodynamic properties considered are not consistent with
the notion that the interlayer pair tunneling must be the dominate pairing mechanism
in these high-Tc cuprate superconductors. Instead, it is found that reasonable agreement
with experiments is obtained for small strengths of pair tunneling, and that large pair
tunneling yields results which do not resemble those of the experiments.

A new method for sampling the exact (within the nodal error) ground state distribution
and nondiflPerential properties of multielectron systems is developed and applied to firstrow
atoms. Calculated properties are the distribution moments and the electronic density
at the nucleus (the 6 operator). For this purpose, new simple trial functions are developed
and optimized.
First, using Hydrogen as a test case, we demonstrate the accuracy of our algorithm
and its sensitivity to error in the trial function. Applications to first row atoms are then
described. We obtain results which are more satisfactory than the ones obtained previously
using Monte Carlo methods, despite the relative crudeness of our trial functions.
Also, a comparison is made with results of highly accurate post-Hartree Fock calculations,
thereby illuminating the nodal error in our estimates.
Taking into account the CPU time spent, our results, particularly for the 8 operator,
have a relatively large variance. Several ways of improving the eflSciency together with
some extensions of the algorithm are suggested.

The ability to learn new reading vocabulary was assessed in 30 grade 3 poor readers
reading approximately one to two years below grade level; the results of the assessment
were compared to the performance abilities of 33 normal readers in grade 3 as obtained
from an earlier study that employed the same approach and stimuli. The purpose of the
study was to examine the strategies employed by poor readers in the acquisition of new
reading vocabulary. Students were randomly assigned to either a treatment group (Mixed
Phonics Explicit), or to a control group (Phonics Implicit). Subjects in the Mixed Phonics
Explicit groups received explicit letter/sound correspondence training. Subjects in the
Phonics Implicit group were asked to re-read the presented pseudo-words, receiving
corrective feedback when necessary. The stimuli on which the subjects were trained
involved a list of six pseudo-words presented in sentences as surnames. The training
involved a teaching and test format on each trial for a total of six trials or until criterion
had been reached. The results suggested that both normal and poor readers engage in
visual learning and verbal coding when acquiring new reading vocabulary. However, poor
readers appear to engage in less verbal coding than normal readers. Between group
comparisons showed no difference between poor and normal readers in trials and errors to
criterion in the visual recognition memory measure. However, normal readers performed
significantly better in reading their visual recognition choices.

The purpose of this study was to determine if Ontario's health and physical
education curriculum contributes sufficiently to ensure the health of our children and
young adults. To determine the curriculum effect, the health risk profile of Niagara
Region's grade 9 students was compared to Canada's adolescent population. All subjects
completed a "Heart Health Lifestyle" survey and were measured for height, weight,
percent body fat, blood pressure, and total cholesterol and performed the 20-metre shuttle
run test as part of their physical and health education classes. The Niagara Region grade 9
population had a healthy risk profile. Aerobic power was inversely related, and
cholesterol levels were positively associated to body mass index and percent body fat in
the whole group analysis. These results indicate that physical education can offer unique
and essential aspects allowing individuals a means to learn and control body movements
and keep physically fit while providing protection against modern disease. Ontario's
health and physical education curriculum does contribute to the health of our children and
adolescents; however, there is a need to implement a stronger mandate for daily vigorous
physical activity.

This study presents information gathered during personal interviews in the area of
challenges that administrators have faced in their careers, and the strategies they have
found to be successful in meeting those challenges. This research is a qualitative study,
using an inductive approach. Five participants were chosen, based on convenience
sampling, with semi-structured interviews that were audio recorded. The theoretical
research found that school violence and stafS'school morale were key challenges facing
administrators, with a variety of approaches suggested to foster success in meeting those
challenges. Some of these approaches included knowledge, team work, an ethic of care,
and having a school vision. From the interviews it became clear that the challenges
administrators faced included those posed by students, including disciplinary issues, those
posed by adults and those posed by government changes in education. In regards to
strategies for success, the interviews revealed three key concepts that were emphasized as
vital. These were the assets of craft knowledge (experience), collegiality, and the use of
other professional resources and educators.

The role of the hospital-employed nurse educator is evolving. Factors influencing
this change include the introduction of standards for nurse educators by the College of
Nurses of Ontario (CNO), a change in the way nurses are educated, the emergence of
nursing as a profession, and hospital restructuring as a result of budgetary constraints.
Two of these influencing factors: the introduction of the updated Standards of Practice
for Registered Nurses and Registered Practical Nurses (1996) and hospital restructuring
occurred over the last 7 years at several hospitals in southern Ontario. Current literature
as well as the Standards of Practice (1996) were utilized to examine the current roles and
responsibilities of nurse educators and subsequently develop a questionnaire to study the
impact of these influencing factors on the role of the nurse educator. This questionnaire
was piloted and revised before its distribution at 4 hospitals in southern Ontario.
Twenty-five of the 41 surveys (61%) distributed were returned for analysis. The data
reflected that the Standards of Practice had a positive influence on the role of the nurse
educator, while hospital restructuring had a negative impact. In addition, many of the
roles and responsibilities identified in the literature were indeed part of the current role
of nurse educators, as well as several responsibilities not captured in the literature. The
predictions for the future of this role in its current state were not positive given the
financial status of the health care system as well as the lack of clarity for the role and the
current level ofjob satisfaction among practicing nurse educators. However, a list of
recommendations were generated which, if implemented, could add clarity to the role
and improve job satisfaction. This could enhance the retention of current nurse educators
and the possibility of recruiting competent nurse educators to the role in the future.

Botrytis cinerea isolates collected from Niagara region were
treated with different concentrations of the fiingicide, iprodione to
test their sensitivity to this fungicide. These Botrytis cinerea isolates
were divided into two groups according to their sensitivity to
iprodione. Those isolates whose growth was inhibited by iprodione
at concentrations < 2|i,g/nil were classified as sensitive isolates.
Isolates that were able to show considerable growth at 2|j,g/ml
iprodione were classified as resistant isolates. Resistant and
sensitive isolates were compared for their morphological and growth
characteristics, conidial germination, virulence on grape berries and
protein banding profiles. The fungicide iprodione at a concentration
of 2|xg/nil inhibited mycelial growth, sporulation and conidial
germination of sensitive isolates but not those of resistant isolates.
The inhibitory effect of the fungicide was greater on mycelial growth
than on conidia germination of the sensitive isolates. Sensitive
isolates produced no sclerotia whereas resistant isolates produced
large number of sclerotia. The fungicide iprodione affected
sclerotial production in the resistant isolates. The number of
sclerotia was decreased by the increase of iprodione in the medium.
Sporulation of resistant isolates was improved significantly in the
presence of iprodione. The resistant isolates were as virulent as the
sensitive isolates on grape berries.
The sensitive and resistant isolates showed similar protein
banding profiles in the absence of iprodione in polyacrylamide gel
electrophoresis studies. Similar protein profiles were also observed
when these isolates were grown in the presence of low iprodione
concentration (0.5|ig/nil). However, in the presence of concentration (0.5|ig/nil). However, in the presence of iprodione at
concentration of 5|Xg/nil, one protein band with approximate
molecular weight of 83 KDa was present in the growing resistant
isolates (and the controls) but was missing in the inhibited sensitive
isolates.

Extensive studies have been initiated to generate enough data to register the methyl
homologue (MBC-MIC, see List of Abbreviations, page 14) of benomyl (MBC-BIC) as a
commercial product through a joint effort between the federal government and Canadian industry.
The objective of this study, as part of the whole project, was to generate fundamental data on the
physical properties of the series of benomyl homologues (MBC-MIC, MBC-EIC, MBC-PIC and
MBC-BIC). These data include the half lives of these compounds in water at the pH range from 2
to 12; they ranged from 0.7 to 10. 1 hours. Standard solutions of these compounds in concentrated
acid were found to be stable for at least two weeks, and in the case of MBC-MIC it was stable at
least 1 month.
Another major goal of this study was to determine the solubility of each compound in water
at different pHs in the range of 1 to 12. The solubility of the compounds ranged from 0.6 jig/mL
to 396 fig/mL. In addition, it was possible to prepare stable stock solutions at concentrations > 1 000
|ig/mL in concentrated nitric acid.
Several aspects of analytical methods have been improved to accurately assess the solubility
and rate of degradation of benomyl and its homologues in alkaline conditions.
The determination of melting points was attempted but all compounds decomposed before
melting.To complement the studies of the benomyl homologue series attempts were made to explore
the presence of any relationships between the structures of the compounds and their properties.
Although there were some exceptions, the compound's solubility decreased and half life increased
as the molecular size increased from the methyl to the butyl analogue.

In the literature on voluntary childlessness there is a lack of research on the types of
occupations held by women who choose not to mother and how their fertility choice
influences their occupational experiences. At the same time, the experience ofwomen
with regard to the childfree choice has not been adequately addressed in contemporary
feminist literature. In the field of education, much has been written about the association
between mothering and teaching. Thus, childfree teachers become particularly interesting
since they made seemingly paradoxical choices in that they chose not to bear and rear
children yet they chose an occupation in which they are surrounded by and responsible for
the daily care of many children. To gain an understanding of the work-related experiences
of childfree women, in-depth interviews were conducted with 7 voluntarily childless
female elementary school teachers from Southern Ontario. In addition, a focus group
interview in which 3 of the 7 childfree teachers participated was conducted. Findings
revealed that these women's "choice" to be childless was the result of complex
circumstances and multiple motivations. Also, despite their decision to forgo the
traditional female role of mother, these women held surprisingly conventional beliefs with
regard to family and gender roles. In addition, these childfree women at times identified
themselves as mother-like when teaching, yet at other times distanced themselves as
teachers from mothers. Finally, results showed that these women experienced both direct
and indirect pronatalist pressures outside as well as inside the workplace as a result of
their childfree status.

Phascolomyces articulosus genomic DNA was isolated from 48 h old hyphae
and was used for amplification of a chitin synthase fragment by the polymerase
chain reaction method. The primers used in the amplification corresponded to two
widely conserved amino acid regions found in chitin synthases of many fimgi.
Amphfication resulted in four bands (820, 900, 1000 and 1500 bp, approximately)
as visualized in a 1.2% agarose gel. The lowest band (820 bp) was selected as a
candidate for chitin synthase because most amplified regions from other fimgi so far
exhibited similar sizes (600-750 bp). The selected fragment was extracted from the
gel and cloned in the Hinc n site of pUC19. The derived plasmid and insert were
designated ^\5C\9'PaCHS and PaCHS respectively. The plasmid pUC19-PaC/fS
was digested by several restriction enzymes and was found to contain BamHl and
HincU sites. Sequencing of PaCHS revealed two intron sequences and a total open
reading frame of 200 amino acids. The derived polypeptide was compared with
other related sequences from the EMBL database (Heidelberg, Germany) and was
matched to 36 other fiilly or partially sequenced fimgal chitin synthase genes. The
closest resemblance was with two genes (74.5% and 73.1% identity) from Rhizopus
oligosporus. Southern hybridization with the cloned fragment as a probe to the PCR
reaction showed a strong signal at the fragment selected for cloning and weaker
signals at the other two fragments. Southern hybridization with partially digested
Phascolomyces articulosus genomic DNA showed a single band. The amino acid
sequence was compared with sequences from other chitin synthase gene classes
using the CLUSTALW program. The chitin synthase fragment from Phascolomyces
articulosus was initially grouped in class n along with chitin synthase fragments
from Rhizopus oligosporus and Phycomyces blakesleeanus which also belong to the
same class, Zygomycetes. Bootstrap analysis using the neighbor-joining method available by CLUSTALW verified such classification. Comparison of PaCHS
revealed conservation of intron positions that are characteristic of chitin synthase
gene fragments of zygomycetous fungi.

The purpose of this qualitative study was to investigate the application of Cognitive
Coaching as a school-based professional development program to improve instructional
thought and decision making as well as to enhance staff perceptions, coUegiality and
school culture. This topic emerged from personal and professional issues related to the
role ofthe reflective practitioner in improving the quality of education, yet cognizant of
the fact that little professional development was available to train teachers to become
reflective.
This case study, positioned within the interpretive sciences, focused on three teachers
and how their experiences with cognitive coaching affected their teaching practices. Their
knowledge, understanding and use of the four stages of instructional thought (preactive,
interactive, reflective and projective) were tested before and at the end of eight coaching
cycles, and again after two months to determine whether they had continued to use the
reflective process. They were also assessed on whether their attitude towards peer
coaching had changed, whether their feelings about teaching had become more positive
and whether their professional dialogue had increased. Three methods of data collection
were selected to assess growth: interviews, observations and joumaling.
Analysis primarily consisted of coding and organizing data according to emerging
themes. Although the professed aim of cognitive coaching was to teach the process in
order that the teachers would become self-analytical and self-modifying, this study found
that the value of the coaching, after trust had been established in both the coach and the
process, was in the dialoguing and the time set aside to do it. Once the coaching stopped
providing the time to dialogue, to examine one's meanings and beliefs, so did the critical self-reflection. As a result ofthe cognitive coaching experience though, all participants
grew in their feelings of efficacy, craftsmanship, flexibility, consciousness and
interdependence.
The actual and potential significance ofthis study was discussed according to
implications for teacher supervision, professional development, school culture, further
areas of research and to my personal growth and development.

This study was a comparative investigation of face-toface
(i.e., proximate) and computer-mediated written (i.e.,
graphic) pre-writing conferences. The participants in this
study were advanced English as a second language students.
The 2 types of conferences were compared in terms of
textual features, participation, and the . degree to which
they were on topic. Moreover, drafts written after the 2
types of conferences were compared in terms of textual
features, and the degree to which they were related to the
conferences. Students produced an equivalent amount of
discourse in an equivalent amount of time in the 2 types of
conferences. The discourse in graphic conferences
displayed greater lexical range, and some evidence suggests
that it was less on-topic. Both these results likely
occurred because the graphic conferences contained more
discourse demonstrating interactive competence.
Participation in graphic conferences was found to be as
balanced or more balanced among students, and among
students and the group leader combined. Overall, the
drafts produced after the 2 types of conferences were of
equivalent length and topical range, but some evidence
suggests that drafts written after proximate conferences
were more related to the conferences.

The value of career education is measured by the extent to which it enhances
students' decision making skills regarding career planning. This is referred to as "career
maturity".
The purpose of this study was to examine what connections could be found
between career education and career maturity within one career planning course. A
senior level career planning class was studied in depth for one semester and five senior
students participated in the study. The five students were interviewed three times during
the semester to determine whether, and to what extent, students feel more prepared
personally to make decisions as a result of a guided course of instruction.
The current trend in education shows an increased emphasis on career education.
The government mandates career education, students are in need of career planning
courses, and parents want students to learn how to effectively make decisions concerning
their future. With this increased emphasis comes the need to evaluate current career
education programs which is why this study is significant and useful.
The central findings were as follows: first, as a result of taking a career planning
course students did increase their career maturity. Second, current career education
planning curriculum was similar to the proposed course of study for career planning
which comes into effect in September 1999. Current curriculum does help to prepare
students to make informed educational and career decisions, a chief aim of the proposed
curriculum. Knowing that this outcome is currently achieved will help when the course
is being organized to fit the new curriculum.

The relative ease to concentrate and purify adenoviruses, their well
characterized mid-sized genome, and the ability to delete non-essential regions from
their genome to accommodate foreign gene, made adenoviruses a suitable candidate
for the construction of vectors. The use of adenoviral vectors in gene therapy,
vaccination, and as a general vector system for expressing foreign genes have been
documented for some time.
In this study, the objective was to rescue a BAV3 E1 or E3 recombinant vector
carrying the kanamycin resistant gene, a dominant selectable marker with useful
applications in studying vectored gene expression in mammalian cells. To accomplish
the objective of this study, more information about BAV3 DNA sequences was required
in order to make the manipulation of the virus genome accessible. Therefore,
sequencing of the BAV3 genome from 1 1 .7% to 30.8% was carried out. Analysis of the
determined sequences revealed the primary structure of important viral gene products
coded by E2 including BAV3 DNA pol and precursor to terminal protein. Comparative
analysis of these proteins with their counterparts from human and non human
adenoviruses revealed important insights as to the evolutionary lineage of BAV3.
In order to insert the kanamycin resistance gene in either E1 or E3, it was
necessary to delete BAV3 sequences to accommodate the foreign gene so as not to
exceed the limit of the packaging capacity of the virus. To construct a recombinant
BAV3 in which a foreign gene was inserted in the deleted E1 region, an E1 shuttle
vector was constructed. This involved the deletion from the viral sequences a region between 1.3% to 9% and inserting the kanamycin resistance gene to replace the
deletion. The E1 shuttle vector contained the left (0%- 53.9%) segment of the genome
and was expected to generate BAV3 recombinants that can be grown and propagated
in cells that can complement the missing E1 functions.
To construct a similar shuttle vector for E3 deletion, DNA sequences extending
from 78.9% to 82.5% (1281 bp) were deleted from within the E3 region that had been
cloned into a plasmid vector. The deleted region corresponds to those that have been
shown to be non-essential for viral replication in cell culture. The resulting plasmid was
used to construct another recombinant plasmid with BAV3 DNA sequences extending
from 37.1% to 100% and with a deletion of E3 sequences that were replaced by
kanamycin resistance gene. This shuttle plasmid was used in cotransfections with
digested viral DNA in an attempt to rescue a recombinant BAV3 carrying the kanamycin
resistance gene to replace the deleted E3.
In spite of repeated attempts of transfection, El or E3 recombinant BAV3 were
not isolated. It seems that other approaches should be applied to make a final
conclusion on BAV3 infectivity.

Palynomorphs from two siliciclastic margins were examined to gain insights into
continental margin architecture. Sea level change is thought to be one of the primary
controls on continental margin architecture. Because Late Neogene glacioeustasy has
been well studied marine sediments deposited during the Late Neogene were examined to
test this concept. Cores from the outer shelf and upper slope were taken from the New
Jersey margin in the western North Atlantic Ocean and from the Sunda Shelf margin in
the South China Sea.
Continental margin architecture is often described in a sequence stratigraphic
context. One of the main goals of both coring projects was to test the theoretical
sequence stratigraphic models developed by a research group at Exxon (e.g. Wilgus et
al., 1988). Palynomorphs provide one of the few methods of inferring continental margin
architecture in monotonous, siliciclastic marine sediments where calcareous sediments
are rare (e.g. New Jersey margin). In this study theoretical models of the palynological
signature expected in sediment packages deposited during the various increments of a
glacioeustatic cycle were designed. These models were based on the modem
palynomorph trends and taphonomic factors thought to control palynomorph distribution.
Both terrestrial (pollen and spores) and marine (dinocysts) palynomorphs were examined.
The palynological model was then compared with New Jersey margin and Sunda Shelf
margin sediments.
The predicted palynological trends provided a means of identifying a complete
cycle of glacioeustatic change (Oxygen Isotope Stage 5e to present) in the uppermost 80
meters of sediment on the slope at the New Jersey margin. Sediment availability, not sea meters of sediment on the slope at the New Jersey margin. Sediment availability, not sea
level change, is thought to be the major factor controlling margin architecture during the
late Pleistocene here at the upper slope. This is likely a function of the glacial scouring of
the continents which significantly increases sediment availability during glacial stages.
The subaerially exposed continental shelf during the lowstand periods would have been
subject to significant amounts of erosion fi:om the proglacial rivers flowing fi-om the
southern regions of the ice-sheet. The slope site is non-depositional today and was also
non-depositional during the last full interglacial period.
The palynomorph data obtained fi-om the South China Sea indicate that the major
difference between the New Jersey Margin sites and the Sunda Shelf margin sites is the
variation in sediment supply and the rate of sediment accumulation. There was
significantly less variation in sediment supply between glacial and interglacial periods
and less overall sediment accumulation at the Sunda Shelf margin.
The data presented here indicate that under certain conditions the theoretical
palynological models allow the identification of individual sequence stratigraphic units
and therefore, allow inferences regarding continental margin architecture. The major
condition required in this approach is that a complete and reliable database of the
contemporaneous palynomorphs be available.

The work to be presented herein illustrates several important facts. First, the
synthesis of BIBOL (19), a 1,4-diol derived from the monoterpene camphor has allowed
us to demonstrate that oxidative dimerizations of enolates can, and do proceed with nearly
complete diastereoselectivity under kinetically controlled conditions. The yield of BIBOL
is now 50% on average, with a 10% yield of a second diastereomer, which is likely the
result of a non-kinetic hydride reduction, thereby affording the epimeric alcohol, 20,
coupled on the exo face of camphor. This implies the production of 60% of a single
coupling diastereomer. No other diastereomers from the reduction were observed. The
utility of BEBOL has been illustrated in early asymmetric additions of diethylzinc to aryl
aldehydes, with e.e.'s as high as 25-30%. '^'
To further the oxidative coupling work, the same methodology which gave rise to
BIBOL was applied to the chiral pool ketone, menthone. Interestingly, this gave an
excellent yield of the a-halohydrin (31), which is the result of a chlorination of menthone.
This result clearly indicates the high stereoselectivity of the process regardless of the
outcome, and has illustrated an interesting dichotomy between camphor and menthone.
The utility of the chlorination product as a precursor other chiral ligands is currently being
investigated. >
'
Finally, a new series of 1,3-diols as well as a new aminoalcohol have successfully
been synthesized from highly diastereoselective aldol/mannich reactions. Early studies
have indicated their potential in asymmetric catalysis, while employing pi-stack interactions
as a means of controlling enantioselective aldol reactions.

This study sought to explore the changing nature of the financial services industry in
Toronto, Canada and the impact that these changes will have on the vocational
educational outcomes required by Ontario Colleges of Applied Arts and Technology
(CAAT) graduates who wish to enter the financial services industry. The study was
descriptive and exploratory, based on both quantitative and qualitative data. Triangulation
of 3 data sources (a collection of newspaper articles from the Toronto Star between July
1999 and June 2000, the calendars of the 25 CAATs, and a survey questionnaire prepared
by me and distributed to subject matter experts who are key practitioners in the financial
services industry) was used. The study contains a discussion of how the financial services
industry is changing. The first question to be answered was: What do current practitioners
in financial services perceive to be the knowledge, skills, and attitudes that will be
required of future graduates for employment within the financial services industry? The
study found that Ontario CAAT's graduates entering the financial services field need both
business and financial services vocational learning outcomes. Colleges should have 2
programs 1 in accounting and 1 in financial services. The report addresses which specific
topics should be included in the financial services program. The second question to be
answered was: How does this anticipated profile of knowledge, skills, and attitudes
change depending on the degree of implementation of the new technologies by the survey
respondent? The study found no pattern. The third question to be answered was: In what
way do existing programs need to change in the area of accreditation as perceived by the
respondents? The study found that for accreditation, 3 credentials should be addressed
within the financial services program. These are the Canadian Securities, the Life Underwriters, and the Certified Financial Planner designations. The last question to be
answered was: What new knowledge, skills, and attitudes need to be incorporated into
college curricula to address changing needs in the employment sector? For each Ontario
CAAT which has a financial services program (excluding accounting), their program was
reviewed in light of the topics as perceived by professionals in the financial services
industry.

My research permitted me to reexamine my recent evaluations
of the Leaf Project given to the Foundation Year students during the
fall semester of 1997. My personal description of the drawing
curriculum formed part of the matrix of the Foundation Core Studies
at the Ontario College of Art and Design. Research was based on the
random selection of 1 8 students distributed over six of my teaching
groups. The entire process included a representation of all grade
levels.
The intent of the research was to provide a pattern of
alternative insights that could provide a more meaningful method of
evaluation for visual learners in an art education setting. Visual
methods of learning are indeed complex and involve the interplay of
many sensory modalities of input.
Using a qualitative method of research analysis, a series of
queries were proposed into a structured matrix grid for seeking out
possible and emerging patterns of learning. The grid provided for
interrelated visual and linguistic analysis with emphasis in
reflection and interconnectedness. Sensory-based modes of learning
are currently being studied and discussed amongst educators as
alternative approaches to learning.
As patterns emerged from the research, it became apparent
that a paradigm for evaluation would have to be a progressive profile
of the learning that would take into account many of the different
and evolving learning processes of the individual. A broader review
of the student's entire development within the Foundation Year Program would have to have a shared evaluation through a cross
section of representative faculty in the program.
The results from the research were never intended to be
conclusive. We realized from the start that sensory-based learning
is a difficult process to evaluate from traditional standards used in
education. The potential of such a process of inquiry permits the
researcher to ask for a set of queries that might provide for a deeper
form of evaluation unique to the students and their related learning
environment. Only in this context can qualitative methods be used to
profile their learning experiences in an expressive and meaningful
manner.

ABSTRACT
Recombinant adenoviruses are currently under intense investigation as potential
gene delivery and gene expression vectors with applications in human and veterinary
medicine. As part of our efforts to develop a bovine adenovirus type 2 (BAV2) based
vector system, the nucleotide sequence of BAV2 was determined. Sixty-six open
reading frames (ORFs) were found with the potential to encode polypeptides that were
at least 50 amino acid (aa) residue long. Thirty-one of the BAV2 polypeptide
sequences were found to share homology to already identified adenovirus proteins.
The arrangement of the genes revealed that the BAV2 genomic organization closely
resembles that of well-characterized human adenoviruses.
In the course of this study, continuous propagation of BAV2 over many
generations in cell culture resulted in the isolation of a BAV2 spontaneous mutant in
which the E3 region was deleted. Restriction enzyme, sequencing and PCR analyses
produced concordant results that precisely located the deletion and revealed that its
size was exactly 1299 bp. The E3-deleted virus was plaque-purified and further
propagated in cell culture. It appeared that the replication of such a virus lacking a
portion of the E3 region was not affected, at least in cell culture.
Attempts to rescue a recombinant BAV2 virus with the bacterial kanamycin
resistance gene in the E3 region yielded a candidate as verified with extensive
Southern blotting and PCR analyses. Attempts to purify the recombinant virus were not
successful, suggesting that such recombinant BAV2 was helper-dependent.
Ten clones containing full-length BAV2 genomes in a pWE15 cosmid vector
were constructed. The infectivity of these constructs was tested by using different transfection methods. The BAV2 genomic clones did appear to be infectious only after
extended incubation period. This may be due to limitations of various transfection
methods tested, or biological differences between virus- and E. co//-derived BAV2 DNA.

This cross-case study explored the extent to which two fitness facilities were
accommodating diversity with respect to age, ethnicity, gender, social class, sex-role
socialization, and persons with a disability among both members and staflf. The sites were
purposely chosen in a large city and a smaller city in order to provide as representative an
example as possible of health clubs within a small sample population. The interview
participants were selected by a combination of stratified, typical case, and snowball
sampling strategies. . , .. ,
The intent of the exploration was a two-fold examination of diversity issues within
both the membership and the staff of the organization. Data were collected and analysis
was done using a triangulation method involving personal interviews, observations, and
facility documentation. The results ofthe study showed that the members and staff at each
facility were rather homogeneous in ethnicity, age, social class, physical ability, and
physical appearance. From a membership standpoint, the environment of the sites
presented the impression of being affordable only to the middle- and upper-middle classes,
unwelcoming to the older, less fit, or overweight participant, economically exclusive for
youth, and nonaccommodating for people with a disability. With respect to staff, the
findings indicated that the fitness facilities purported to be team-oriented in theory, but
were hierarchical in practice, with the major decision making being made by the male
executives. The paper concludes with the recommendation that students must be given a
practical toolkit for dealing with these issues in their postsecondary courses.

Gamma-aminobutyric acid (GAB A) is a ubiquitous non-protein amino acid synthesized via
the decarboxylation of L-glutamate in a reaction catalyzed by the cytosolic enzyme L-glutamate
decarboxylase (GAD). In animals it functions as an inhibitory neurotransmitter. In plants it
accumulates rapidly in response to various stresses, but its function remains unclear. The hypothesis
that GABA accumulation in leaf tissue may function as a plant resistance mechanism against
phytophagous insect activity was investigated.
GABA accumulation in response to mechanical stimulation, mechanical damage and insect
activity was demonstrated. In wt tobacco (Nicotiana tabacum cv Samsun), mechanical stimulation
or damage caused GABA to accumulate within 2 min from mean levels of 14 to 37 and 1~9 nmol
g-l fresh weight (FW), respectively. In the transgenic tobacco strain CaMVGAD27c overexpressing
Petunia GAD, the same treatments caused GABA to accumulate from 12 to 59 and 279 nmol g-l FW,
respectively. In the transgenic tobacco strain CaMVGADilC 11 overexpressing Petunia GAD lacking
an autoinhibitory domain, mechanical stimulation or damage caused GABA to accumulate from 180
to 309 and 630 nmol g-l FW, respectively. Ambulatory activity by tobacco budworm (TBW) larvae
(Heliothis virescens) on leaves of CaMVGAD27c tobacco caused GABA to accumulate from 28 to
80 nmol g-l FW within 5 min. Ambulatory and leaf-rolling activity by oblique banded leaf roller
(OBLR) larvae (Choristoneura rosaceana cv Harris) on wt soybean leaves (Glycine max cv
Harovinton) caused GABA to accumulate from 60 to 1123 nmol g-l FW within 20 min. Increased
GABA levels in leaf tissue were shown to affect phytophagous preference in TBW larvae presented
with wt and transgenic tobacco leaves. When presented with leaves of Samsun wt and CaMVGAD27c plants, TBW larvae consumed more wt leaf tissue (640 ± 501 S.D. mm2
) than
transgenic leaf tissue (278 ± 338 S.D. mm2
) nine times out of ten. When presented with leaves of
Samsun wt and CaMVGAD~C11 plants, TBW larvae consumed more transgenic leaf tissue (1219
± 1009 S.D. mm2
) than wt leaf tissue (28 ± 31 S.D. mm2
) ten times out of ten.
These results indicate that: (1) ambulatory activity of insect larvae on leaves results in
increased GABA levels, (2) transgenic tobacco leaves with increased capacity for GABA synthesis
deter feeding, and (3) transgenic tobacco leaves with constitutively higher GABA levels stimulate
feeding.

Despite the increasing public profile of lesbian childbearing, public health resources for
expectant women often bear heterosexist assumptions and create barriers to accessing
information relevant to lesbian mothering experiences. This descriptive, exploratory study
examined one lesbian couple's perceived educational needs for effective support, barriers to
access, strategies for locating care, and the impact of childbearing on their lives, as well as their
reflections on inviting ways to offer supportive practices in a public health context.
A case study approach used feminist ethnographic methodology and purposeful
convenience sampling. A prenatal and a postnatal open-ended interview were completed with 1
white, middle-class, able, lesbian childbearing couple, each ofwhom has birthed as coparent and
biological mother in this couple relationship.
Despite this couple's immense situated privilege, they struggled to locate the support they
sought for childbearing in a way that offered optimal emotional and physical care from the
preconceptual to postpartum stages and which maintained confidentiality or anonymity as
desired. They created meaningful care through personal networks. The findings were framed
using invitational and feminist theories: how people, places, programs, processes, policies, and
politics contributed to educational support. A three part conceptual framework emerged which
identified components of access to support: perceived safety of resources, disclosure status,
situated privilege, and public or private availability of information. The consequences of lack of
public access to comprehensive childbearing care for lesbian women and their communities are
described. Educational possibilities addressed systemic heterosexism through the development of
sensitive educators, meaningful curriculum, program planning, explicit policies, community
partnerships, and political leadership with respect to both institutional and research venues.

The purpose of this study was to determine the effect that calculators have
on the attitudes and numerical problem-solving skills of primary students. The
sample used for this research was one of convenience. The sample consisted of
two grade 3 classes within the York Region District School Board. The students
in the experimental group used calculators for this problem-solving unit. The
students in the control group completed the same numerical problem-solving unit
without the use of calculators.
The pretest-posttest control group design was used for this study. All
students involved in this study completed a computational pretest and an attitude
pretest. At the end of the study, the students completed a computational posttest.
Five students from the experimental group and five students from the control
group received their posttests in the form of a taped interview. At the end of the
unit, all students completed the attitude scale that they had received before the
numerical problem-solving unit once again. Data for qualitative analysis included
anecdotal observations, journal entries, and transcribed interviews. The constant
comparative method was used to analyze the qualitative data. A t test was also
performed on the data to determine whether there were changes in test and
attitude scores between the control and experimental group.
Overall, the findings of this study support the hypothesis that calculators
improve the attitudes of primary students toward mathematics. Also, there is some
evidence to suggest that calculators improve the computational skills of grade 3
students.

The frequency and type of agonistic displays involved in male-male encounters should
be significantly influenced by the presence of females. Discrete agonistic displays vary in
energy expenditure and risk, and therefore should be dependent on available resources. The
influence of live females and the scent of females, on the frequency of male agonistic displays
was observed in a laboratory terrarium using the field cricket Gryllus bimaculatus. The effect
of energy constraints on display frequency was also determined. Half the males were fed a diet
high in protein and fet; the other males were fed a lower quality diet, for a 7-11 day period.
The frequency of five individual displays and mating frequency were recorded using an Event
Recorder and notebook. Each group of males was presented with three experimental
conditions, over three days, involving the presence or absence of live females and female scent.
The presence of females elicited an increase in all displays except antennation; female
scent increased the frequency of antennations, mandible flares and grapples, but to a lesser
extent than did live females. The frequency of grapples significantly increased for males fed
the high quality diet; however diet did not influence the other displays. The combined
influence of diet and condition was significant for mandible flare only. Mating frequency was
not influenced by diet. However, the frequency ofthe displays were positively correlated with
mating frequency for high quality fed males. Escalated displays involving high costs, such as
grapple and mandible flare, increased in frequency when the benefits of winning contests were
high in G.bimaculatus. Escalation to grapple behaviour was less evident for males fed the
lower quality diet as this imposed energy constraints on high cost displays.

The effects oftwo types of small-group communication, synchronous computer-mediated
and face-to-face, on the quantity and quality of verbal output were con^ared. Quantity
was deiSned as the number of turns taken per minute, the number of Analysis-of-Speech
units (AS-units) produced per minute, and the number ofwords produced per minute.
Quality was defined as the number of words produced per AS-unit. In addition, the
interaction of gender and type of communication was explored for any differences that
existed in the output produced. Questionnaires were also given to participants to
determine attitudes toward computer-mediated and face-to-face communication. Thirty
intermediate-level students fi-om the Intensive English Language Program (lELP) at
Brock University participated in the study, including 15 females and 15 males. Nonparametric
tests, including the Wilcoxon matched-pairs test, Mann-Whitney U test, and
Friedman test were used to test for significance at the p < .05 level. No significant
differences were found in the effects of computer-mediated and face-to-face
communication on the output produced during follow-up speaking sessions. However, the
quantity and quality of interaction was significantly higher during face-to-face sessions
than computer-mediated sessions. No significant differences were found in the output
produced by males and females in these 2 conditions. While participants felt that the use
of computer-mediated communication may aid in the development of certain language
skills, they generally preferred face-to-face communication. These results differed fi-om
previous studies that found a greater quantity and quality of output in addition to a greater
equality of interaction produced during computer-mediated sessions in comparison to
face-to-face sessions (Kern, 1995; Warschauer, 1996).

The effects of the female postmating odour on male sexual behaviour were examined in
Heliconius erato and H. charithonia (Lepidoptera: Nymphalidae). Predictions from the antiaphrodisiac
hypothesis were tested using the two reproductive strategies of these species. Within the pupal mating
strategy, results from behavioural experiments quantified and statistically tested dispersal rates of
pupal-perched males to the presence of stimuli with and without the postmating odour. Results do not
support an antiaphrodisiac function to the postmating odour. Similarly, within the adult courtship
strategy, behavioural test results indicate that males do not alter their expenditure of energy in terms of
either the duration or frequency of courtship behaviours elicited by females with and without the
postmating odour. The data from both experiments did not support the antiaphrodisiac hypothesis for
the function of the female postmating odour. A novel hypothesis predicting that the postmating female
odour acts as an oviposition-deterring pheromone is presented.

N'-coumaroyl spermidine (NlCSpd) is a plant derived chemical which is proposed to
belong to a class of low molecular weight neuroactive substances called phenolic polyamines.
NlCSpd is stnicturally similar to glutamate receptor blocking toxins found in certain spiders and
wasps, such as JSTX-3 and NSTX-3 found in Nephila spiders.
The goal of the present study was to determine if plant-derived phenolic polyamines act
like other structurally related chemicals found in Arthropod venoms, such as JSTX-3, and
whether they can be classified in the same pharmacological group as the spider and wasp toxins.
A comparison was made to determine the relative potencies of various phenolic polyamines fi-om
plants and insect venoms. This comparison was done by measuring the effect of various
concentrations ofNlCSpd on the amplitude of excitatory postsynaptic potentials (EPSPs) elicited
in muscle of the crayfish Proccanbarus clarkii. NlCSpd was also tested on L-glutamate induced
potentials to determine if a postsynaptic component to sj^naptic block occurs.
NlCSpd and an analogue with an a longer polyamine chain, NlCSpm, blocked EPSPs in a
dose dependent manner, NlCSpd having an IC50 of lOOnM. NlCSpd also blocked L-glutamate
induced potentials. The two main components of the NlCSpd molecule alone are insufficient for
activity.
NlCSpd acts postsynaptically by interfering with crayfish glutamatergic synaptic
transmission, likely blocking glutamate receptors by interacting with the same site(s) as other
phenolic polyamines. Certain moieties on the polyamines molecule are necessary for activity while
others are not.

The purpose of the current undertaking was to study the electrophysiological
properties of the sleep onset period (SOP) in order to gain understanding into the
persistent sleep difficulties of those who complain of insomnia following mild traumatic
brain injury (MTBI). While many believe that symptoms of post concussion syndrome
(PCS) following MTBI resolve within 6 to 12 months, there are a number of people who
complain of persistent sleep difficulty. Two models were proposed which hypothesize
alternate electrophysiological presentations of the insomnia complaints of those
sustaining a MTBI: 1) Analyses of standard polysomnography (PSG) sleep parameters
were conducted in order to determine if the sleep difficulties of the MTBI population
were similar to that of idiopathic insomniacs (i.e. greater proportion ofREM sleep,
reduced delta sleep); 2) Power spectral analysis was conducted over the SOP to
determine if the sleep onset signature of those with MTBI would be similar to
psychophysiological insomniacs (characterized by increased cortical arousal). Finally,
exploratory analyses examined whether the sleep difficulties associated with MTBI could
be explained by increases in variability of the power spectral data.
Data were collected from 9 individuals who had sustained a MTBI 6 months to 5
years earlier and reported sleep difficulties that had arisen within the month subsequent
to injury and persisted to the present. The control group consisted of 9 individuals who
had experienced neither sleep difficulties, nor MTBI. Previous to spending 3 consecutive
uninterrupted nights in the sleep lab, subjects completed questionnaires regarding sleep
difficulties, adaptive functioning, and personality.

There is much evidence to support an age-related decline in source memory
ability. However, the underlying mechanisms responsible for this decline are not well
understood. The current study was carried out to determine the electrophysiological
correlates of source memory discrimination in younger and older adults.
Event-related potentials (ERPs) and continuous electrocardiographic (ECG) data
were collected from younger (M= 21 years) and older (M= 71 years) adults during a
source memory task. Older adults were more likely to make source memory errors for
recently repeated, non-target words than were younger adults. Moreover, their ERP
records for correct trials showed an increased amplitude in the late positive (LP)
component (400-800 msec) for the most recently presented, non-target stimuli relative to
the LP noted for target items. Younger adults showed an opposite pattern, with a large
LP component for target items, and a much smaller LP component for the recently
repeated non-target items.
Computation of parasympathetic activity in the vagus nerve was performed on the
ECG data (Porges, 1985). The resulting measure, vagal tone, was used as an index of
physiological responsivity. The vagal tone index of physiological responsivity was
negatively related to the LP amplitude for the most recently repeated, non-target words in
both groups, after accounting for age effects.
The ERP data support the hypothesis that the tendency to make source memory
errors on the part of older adults is related to the ability to selectively control attentional
processes during task performance. Furthermore, the relationship between vagal tone and ERP reactivity suggests that there is a physiological basis to the heightened reactivity
measured in the LP response to recently repeated non-target items such that, under
decreased physiological resources, there is an impairment in the ability to selectively
inhibit bottom-up, stimulus based properties in favour of task-related goals in older
adults. The inconsistency of these results with other explanatory models of source
memory deficits is discussed. It is concluded that the data are consistent with a
physiological reactivity model requiring inhibition of reactivity to irrelevant, but
perceptually-fluent, stimuli.

Objective. Smoking prevalence is highest among the young adult cohort. Postsecondary
students are no exception. Although many students intend to quit smoking, no
research has established what methods best promote reductions in, or complete
abstinence from smoking. This randomized controlled trial examined the effectiveness of
three self-help smoking cessation interventions.
Method. On six post-secondary campuses, 483 smokers who voluntarily accessed
Leave The Pack Behind (a tobacco control initiative) were randomly assigned to one of
three smoking cessation interventions: One Step At A Time (a 2-booklet, *gold standard'
program for adults); Smoke|Quit (a newly-developed 2-booklet program for young adult
students); and usual care (a 'Quit Kit' containing a booklet on stress management,
information about pharmacological quitting aides and novelty items). All participants
also received one proactive telephone support call from a peer counsellor.
During the study, 85 participants withdrew. The final sample of 216 students who
completed baseline questionnaires and 12-week follow-up telephone interviews was
representative of the initial sample in terms of demographic characteristics, and smokingquitting-
related variables.
Results. Whether participants quit smoking depended upon treatment condition,
^(2, N=2\6) = 6.34, p = .04, with Smoke|Quit producing more successfijl quitters
(18.4%) than One Step At A Time (4.5%) or the Quit Kit (1 1.4%). On average,
participants had quit 53.46 days, with no significant difference across treatments. Selfefficacy
also increased. Use of the intervention or other quitting aides was not associated
with treatment condition.
Among the 191 participants who did not quit smoking, treatment condition did
not influence outcomes. Overall, 46.2% had made a quit attempt. Significant decreases in
weekly tobacco consumption and increases in self-efficacy to resist smoking were
observed from baseline to follow-up.
Conclusion. Post-secondary institutions represent a potentially final opportunity
for age-targeted interventions. Self-help resources tailored to students' social and
contextual characteristics will have considerable more impact than stage-only tailored
interventions. Both reduction and abstinence outcomes should be emphasized to
positively support students to stop smoking.
