    • The Transition Online: A Mixed-Methods Study of the Impact of COVID-19 on Students with Disabilities in Higher Education

      Mullins, Laura E; Mitchell, Jennifer (Sciedu Press, 2021-09-05)
      Following the World Health Organization’s announcement of the global pandemic because of the Coronavirus Disease 2019, most Canadian universities transitioned to offering their courses exclusively online. One group affected by this transition was students with disabilities. Previous research has shown that the university experience for students with disabilities differs from those of their non-disabled peers. However, their unique needs are often not taken into consideration. As a result, students can become marginalized and alienated from the online classroom. In partnership with Student Accessibility Services, this research revealed the impact of the transition to online learning because of the pandemic for university students with disabilities. Students registered with Student Accessibility Services completed a survey about the effects of online learning during a pandemic on the students’ lives, education, and instructional and accommodation. It was clear from the results that online education during COVID-19 affected all aspects of the students’ lives, particularly to their mental health. This research provided a much-needed opportunity for students with disabilities to share the factors influencing their educational experience and identified recommendations instructors should consider when developing online courses to increase accessibility and improve engagement.
    • The role of the arousal system in age‐related differences in cortical functional network architecture

      Guardia, Tiago; Geerligs, Linda; Tsvetanov, Kamen A.; Ye, Rong; Campbell, Karen L. (Wiley, 2021-10-29)
      A common finding in the aging literature is that of the brain's decreased within- and increased between-network functional connectivity. However, it remains unclear what is causing this shift in network organization with age. Given the essential role of the ascending arousal system (ARAS) in cortical activation and previous findings of disrupted ARAS functioning with age, it is possible that age differences in ARAS func- tioning contribute to disrupted cortical connectivity. We test this possibility here using resting state fMRI data from over 500 individuals across the lifespan from the Cambridge Center for Aging and Neuroscience (Cam-CAN) population-based cohort. Our results show that ARAS-cortical connectivity declines with age and, consistent with our expectations, significantly mediates some age-related differences in connec- tivity within and between association networks (specifically, within the default mode and between the default mode and salience networks). Additionally, connectivity between the ARAS and association networks predicted cognitive performance across several tasks over and above the effects of age and connectivity within the cortical networks themselves. These findings suggest that age differences in cortical connec- tivity may be driven, at least in part, by altered arousal signals from the brainstem and that ARAS–cortical connectivity relates to cognitive performance with age.
    • Landscape Aware Algorithm Configuration

      Dennis, Cody; Department of Computer Science
      The issue of parameter selection cannot be ignored if optimal performance is to be obtained from an algorithm on a specific problem or if a collection of algorithms are going to be compared in a fair manner. Unfortunately, adequately addressing the issue of parameter selection is time consuming and computationally expensive. Searching for appropriate control parameters generally requires much more time than actually solving the problem at hand due to the need to perform many complete runs of the target algorithm. The number of runs required to obtain thorough and equal coverage of the parameter space grows exponentially with the number of parameters. As a result, costs associated with parameter selection become a limiting factor in the scale of problems that can be investigated. The primary goal of this work is to reduce the costs of parameter selection. In pursuit of this goal, this thesis examines the use of neural networks to intelligently select appropriate control parameter values based on the characteristics of the problem at hand. Two general purpose approaches are evaluated: one that predicts a single set of control parameters to use throughout a run of the target algorithm; and, another that dynamically adjusts algorithm control parameters at run time. These approaches are examined in detail using the Particle Swarm Optimization algorithm. A comparison with state of the art automated tools for control parameter selection indicates that the cost of parameter selection can be significantly reduced.
    • Episode 11: On Disability

      Steer, Linda (2021-10-29)
      Episode 11: On Disability This episode of Unboxing the Canon introduces the topic of disability and the visual arts, looking at both historical and contemporary examples. We consider the near absence of visible disability in the history of Western art and discuss how some contemporary artists are representing disability in powerful ways. Beginning with Diego Velázquez’s 1656 painting Las Meninas, this episode examines it and other historical works through the ideas of contemporary artist, writer and disability activist, Riva Lehrer. Then we turn towards the work of Persimmon Blackbridge, a Canadian artist whose work touches on disability, institutionalization, censorship, and queer identity. We demystify the artist-genius myth and end with a brief discussion about how curatorial choices can make art more accessible.
    • Episode 10: Thinking and Rethinking Orientalism

      In this episode, called “Thinking and Rethinking Orientalism,” we examine Orientalism as a particular version of the Western gaze that influenced many 19th century European painters. The Western or European gaze treats non-Western subjects as different and inferior, but also as exotic, mysterious, or enticing. After examining the orientalist visual tropes in paintings by Gérôme and Delacroix, we turn towards contemporary artists. Moroccan photographer Lalla Essaydi creates meaningful portraits of Muslim women that challenge perceptions of Arab female identity. Monir Shahroudy Farmanfarmaian was an Iranian artist whose works combine Eastern and Western influences into a unique sculptural style. We take a look at her series Fourth Family.
    • Fast Professors, Research Funding, and the Figured Worlds of Mid-Career Ontario Academics

      Acker, Sandra; McGinn, Michelle K. (Brock University, 2021-07-15)
      Heightened pressures to publish prolifically and secure external funding stand in stark contrast to the slow scholarship movement. This article explores ways in which research funding expectations permeate the “figured worlds” of 16 mid-career academics in education, social work, sociology, and geography in seven universities in Ontario, Canada. Participants demonstrated a steady record of research accomplishment and a commitment to social justice in their work. The analysis identified three themes related to the competing pressures these academics described in their day-to-day lives: funding, challenges, and the fast professor. Participants spoke about their research funding achievements and struggles. In some cases, they explained how their positioning, including gender and race, might have affected their research production, compared to colleagues positioned differently. Their social justice research is funded, but some suspect at a lower level than colleagues studying conventional topics. Challenges might be located in the backstage (personal and home lives) or the frontstage (university or funding agency policies or embedded in the research itself). In aiming for the impossible standards of a continuously successful research record, these individuals worked “all the time.” Advocates claim that slow scholarship is not really about going slower but rather about maintaining quality and caring in one’s work; yet, participants’ accounts suggest they perceive few options other than to perform as “fast professors.” At mid-career, they question whether and how they can keep up this aspect of their figured worlds for 20 or more years.
    • Remote doctoral supervision experiences: Challenges and affordances

      Wisker, Gina; McGinn, Michelle K.; Bengtsen, Søren S. E.; Lokhtina, Irina; He, Faye; Cornér, Solveig; Leshem, Shosh; Inouye, Kelsey; Löfström, Erika (Informa UK Limited, 2021-11-25)
      The global pandemic has forced academics to engage in remote doctoral supervision, and the need to understand this activity is greater than ever before. This contribution involved a cross-field review on remote supervision pertinent in the context of a global pandemic. We have utilised the results of an earlier study bringing a supervision model into a pandemic-perspective integrating studies published about and during the pandemic. We identified themes central to remote supervision along five theory-informed dimensions, namely intellectual/cognitive, instrumental, professional/technical, personal/emotional and ontological dimensions, and elaborate these in the light of the new reality of remote supervision.
    • Living in Two Cultures: Chinese Canadians’ Perspectives on Health

      Lu, Chunlei; McGinn, Michelle K.; Xu, Xiaojian; Sylvestre, John (Springer Science and Business Media LLC, 2016-03-21)
      OBJECTIVES: Chinese people have distinctive perspectives on health and illness that are largely unrecognized in Western society. The purpose of this descriptive study was to develop a profile of Chinese immigrants’ beliefs and practices related to diet, mental and social health, and sexual health. METHODS: A quantitative survey with descriptive and correlational analyses was employed to examine 100 first-generation Chinese immigrants living in four urban centres across Canada (Vancouver, Toronto, Halifax, and St. Catharines). RESULTS: Although most Chinese immigrants preferred a Chinese diet, where they resided affected the groceries they bought and the meals they ate. Almost all participants reported their mental health was important to them and most felt comfortable discussing mental health issues with others. However, only a third would see a psychiatrist if they believed they had a mental health problem. Most participants believed social relationships were important for their health. Only a small number of participants, however, preferred making friends with mainstream Caucasian Canadians. More men than women believed sexuality contributed to health and were comfortable talking about sexual health. CONCLUSION: Chinese immigrants should be encouraged to be more engaged in the larger community in order to fully integrate themselves into Canadian society while still being encouraged to retain their healthy practices. These findings may help educators and practitioners enhance their understandings of Chinese immigrants’ perspectives on health and develop culturally competent education and services in health care and health promotion.

    • Episode 9: Portraits of Rulers

      Steer, Linda (2021-05-20)
      In this episode, “Portraits of Rulers,” I take a look at the history of portraits of rulers in the canon of Western art and examine how portraits engage with structures of power. Beginning with French and English royalty in the 17th and 18th century, I end with a visual analysis of Kehinde Wiley’s portrait of former American President Barack Obama. Focusing on these rulers allows us to see how European portrait conventions use a number of visual cues, from clothing, pose, setting, and the objects included within the painting, to convey wealth, power and the right to rule. Examining a portrait of late 17th-century Queen Marie Antoinette allows us to see gender differences in royal portraiture. Looking closely at Obama’s portrait reveals the ways in which Wiley both adopted and refined European portrait conventions in a way that makes his portrait stand out among portraits of other American presidents.

The book contains administrative details of the Regiment including appointments, promotions, and orders. Some of the entries are signed by Walker Powell, P.L. MacDougall, and W.D. Otter. William Dillon Otter became an accomplished militia and army officer who fought with the Queen’s Own Rifles against the Fenians at the Battle of Ridgeway in 1866. Book 2 contains entries dated from January 1, 1866 to December 23, 1867. The entries are signed by W.D. Otter, Robert Denison, W.S. Durie, J.S. MacDougall, C.H. Cormon, and M. Campbell. The entries dated from May 31, 1866 to June 4, 1866 provide some brief information on the activities and leadership of the QOR while they were stationed in Port Colborne and Fort Erie during the Fenian Raid. The entry dated at Port Colborne on June 1, 1866 contains instructions for a guard, noting that “the orders of the Sentries will be the usual ones & in addition those of the one on the Pier will be to pay particular attention and give instant warning in the event of the entry into the Harbour of any vessel carrying armed men in connection with which there may be any suspicious circumstances”. The same entry states that a picquet will be mounted each evening “to patrol the Canal Side from the end of the pier to the east part of the village and upon the main road leading into the later from Fort Erie. The orders of the said picquet will be to report at once to the Commanding Officer the approach of any body of men advancing on the place or any other suspicious circumstances and to arrest and hand over to the Serg. of the guard as prisoners all Volunteers out of their Billets without pass from the Commanding Officer after the sounding of the last post which will be 10 p.m.”

    • George Crawford fonds, 1813-1868, n.d.

      Cameron, Chantal (2021-11-30)
      Most of the fonds consists of correspondence written to George Crawford, a Pennsylvania State Legislator. The bulk of these letters were written to him while he was serving as a Pennsylvania State Legislator from 1831 to 1834. Other materials include rolls for labourers working on the Pennsylvania Canal, legal documents, accounts, printed material, receipts, and newspapers. Correspondence, 1817-1868, n.d. Contains 268 letters. Many of the letters are from constituents, fellow legislators, judges, and lawyers who were looking for Crawford’s support on their bills, need for a charter, petitions, remonstrances, or inquiries. An interesting letter to George Crawford from his son R.A. Crawford in 1857 provides a detailed description of his trip to Niagara Falls, including sightseeing excursions to Goat Island, the suspension bridge, Barnett’s Museum, and Lundy’s Lane.

    • Strategies for Evolving Diverse and Effective Behaviours in Pursuit Domains

      Cowan, Tyler James; Department of Computer Science
      Evolutionary algorithms have a tendency to overuse and exploit particular behaviours in their search for optimality, even across separate runs. The resulting set of monotonous solutions caused by this tendency is a problem in many applications. This research explores different strategies designed to encourage an interesting set of diverse behaviours while still maintaining an appreciable level of efficacy. Embodied agents are situated within an open plane and play against each other in various pursuit game scenarios. The pursuit games consist of a single predator agent and twenty prey agents, with the goal always requiring the predator to catch as many prey as possible before the time limit is reached. The predator's controller is evolved through genetic programming while the preys' controllers are hand-crafted. The fitness of a solution is first calculated in a traditional manner. Inspired by Lehman and Stanley's novelty search strategy, the fitness is then combined with the diversity of the solution to produce the final fitness score. The original fitness score is determined by the number of captured prey, and the diversity score is determined through the combination of four behaviour measurements. Among many promising results, a particular diversity-based evaluation strategy and weighting combination was found to provide solutions that exhibit an excellent balance between diversity and efficacy. The results were analyzed quantitatively and qualitatively, showing the emergence of diverse and effective behaviours.
