The utilisation of coprophilous fungal spores for discerning late Quaternary megaherbivore extinctions in Canada
Northern ecosystems are experiencing dramatic changes due to anthropogenically accelerated climatic warming. Understanding the impacts of this on fauna and flora is key to predicting the long-term sustainability of ... -
My life compared to others: Examining the impact of better or worse off comparisons on young adults’ beliefs about how their life satisfaction is unfolding over time
Many individuals perceive their lives as becoming increasingly satisfying over time. Drawing on social comparison theory and research based on the better/worse-than-average effects, the present research investigated ... -
An adaptive 4-week robotic training program of the upper limb for persons with multiple sclerosis
It is suggested that repetitive movements can initiate motor recovery and improve motor learning in populations with neurological impairments and this process can be optimized with robotic devices. The repetitive, reproducible ... -
Evaluating Behavioural Skills Training via Telecommunication to Teach Mediators to Facilitate Acceptance and Commitment Training
Multiple randomized control trials have demonstrated the effectiveness of acceptance and commitment training (ACT) for improving the quality of life of numerous populations, including caregivers of children with NDDs. ... -
Evaluating Committed Actions during Acceptance and Commitment Training for Caregivers of People with Neurodevelopmental Disabilities
Caregivers of people with neurodevelopmental disabilities (NDDs) often experience greater levels of psychological distress (i.e., stress, depression, anxiety) than caregivers of people without disabilities. Prolonged ... -
Understanding community perspectives: A Case Study of a Bottom-Up Sport-For-Development initiative in rural Africa
The first wave of Sport for Development (SfD) initiatives made bold assumptions that sport was inherently good for participants and could achieve social and developmental outcomes (Levermore, 2008; Lyras & Peachey, 2011). ... -
Development of Universal Biosensing Platforms Based on CRISPR/Cas12a systems
CRISPR/Cas technologies possess the promising potential to affect biosensing field by providing a sensitive, precise, rapid, versatile and cost-effective method for diverse target detections. This thesis focusses on the ... -
The Effects of a Self-Management Treatment Package on Physical Activity in University Students with Depressive Symptoms
Research demonstrates that exercise interventions are effective in decreasing depressive symptoms; however, these treatments are infrequently implemented in clinical practice. Self-management techniques offer an effective, ... -
RuPaul's Drag Race and the Toronto Drag Scene
The debut of the television show RuPaul’s Drag Race (Barbato, Bailey, and Charles) in 2009 marked the start of a new drag boom. The program’s commercial success throughout the 2010s brought drag performance into the ... -
Sleepers and Creepers, Colony Polymorphisms in Metarhizium robertsii
In this thesis I attempt to identify, describe, and explain the vast colony polymorphism differences observed in Metarhizium robertsii from a physical and genetic standpoint. These descriptions provide a framework to explain ... -
Flood Survival Strategies of Overwintering Snakes
This thesis investigates snake flood survival during hibernation and how anthropogenic habitat alteration and climate variability may affect habitat quality and overwintering survival. Chapter one reviews the current ... -
Effects of Sensory Processing Patterns on Inhibitory Control as a Function of ADHD-traits and Trait Anxiety
Anxiety and ADHD (traits) have been shown to co-occur in both clinical and non-clinical populations. In addition, both anxiety and ADHD are independently associated with atypical sensory processing. However, there has been ... -
The hydrology of northern boreal lakes in the Taiga Shield and Plains, Northwest Territories and the importance of catchment characteristics in mediating responses to climate
Freshwater lakes are prominent features across northern boreal regions and are sensitive to changing climate conditions. This study, spanning the 2017-18 ice-free seasons, broadens our understanding of how variable climate ... -
Comparing an Interdependent and Dependent Group Contingency to Increase Physical Activity in Students During Recess
Physical activity is defined as any body movement that requires energy expenditure. It has important physiological, mental health, academic, and cognitive benefits for children and youth. Despite these advantages, a large ... -
Data mining using L-fuzzy concept analysis.
Association rules in data mining are implications between attributes of objects that hold in all instances of the given data. These rules are very useful to determine the properties of the data such as essential features ... -
Comparing High-Probability Demands With and Without Food to Increase the Consumption of Healthy Food in Picky Eaters
The high-probability (high-p) instructional sequence is a nonintrusive antecedent-based intervention that involves the presentation of a series of high-p demands followed by one low- probability demand. To date, only nine ... -
Wearable activity monitors and goals: Perceptions on physical activity, attitudes and motivational outcomes
Evidence attesting to the benefits of wearable activity monitors for increasing PA has been reported (USDHHS, 2018). Goal setting is one behavior change technique that often accompanies wearable activity monitors and has ... -
