At A Crossroads: Crisis, Vulnerability, And The Possibility Of Transformation Of Nature-Based Tourism In Canada, Brooklyn Rushton

Theses and Dissertations (Comprehensive)

We live in an era shaped by a global polycrisis, where climate change, pandemics, economic shocks, geopolitical tensions, and social inequities are converging to create complex, cascading, and compounding risks. For Canada’s nature-based tourism sector, situated at the nexus of social and ecological systems, the polycrisis both amplifies the vulnerabilities of tourism and highlights tourism’s role in perpetuating global risks. Recognizing this duality, this dissertation examines how crises amplify systemic vulnerabilities while also acting as leverage points for transformative change in Canada’s nature-based tourism sector, drawing on geography, systems thinking, resilience theory, regenerative tourism, and futures thinking scholarship.

Moral Identity And Cognitive Mechanisms In Moral Decision-Making, Zachariah I. Hamzagic

Theses and Dissertations (Comprehensive)

Moral identity can be broadly conceptualized as the degree to which an individual places moral values as directly relevant to their personal identity. A recently introduced developmental framework of moral identity argues that moral identity can be conceptualized as a lifelong goal. According to this theoretical framework, the moral identity goal (i.e., to be a moral person and engage in moral action) becomes stronger over the course of development by becoming more abstract (i.e., general), internalized (to satisfy personal ideals) and promotion (i.e., action) oriented. Additionally, the strength of the moral identity goal predicts moral functioning. To date there has …

A Novel Federated Llm Framework For Distributed Traffic Modelling In Intelligent Transportation Systems, Seerat Kaur

Theses and Dissertations (Comprehensive)

Intelligent transportation systems (ITS) depend on accurate traffic prediction to support congestion management, infrastructure planning, and real-time operational decisions. Despite substantial progress in data-driven forecasting, several challenges continue to limit practical deployment: traffic data is distributed across independent regional authorities, making centralized aggregation infeasible, standard federated aggregation strategies ignore traffic-specific characteristics that meaningfully affect model quality, and existing models produce only numerical outputs without interpretable reasoning that urban planners can act upon. This thesis addresses these challenges through four contributions that collectively advance privacy-preserving, explainable, and scalable traffic forecasting.

The first contribution provides a systematic review of 129 peer-reviewed publications, …

These include limited land access, insufficient funding, inadequate training pathways, and experiences of racial isolation in rural contexts. …

Intelligent Electric Vehicle Routing For Goods Delivery Under Real-Time Traffic Conditions: A Comparative Framework For Modular Battery Swapping And Dynamic Wireless Charging, Ranjit Jakharabhai Odedra

Theses and Dissertations (Comprehensive)

Electric vehicles (EVs) are becoming central to sustainable and intelligent transportation systems, particularly in urban logistics, where reducing emissions, congestion, and operating inefficiencies is increasingly important. Despite their environmental advantages, the large-scale deployment of EVs in delivery operations remains constrained by limited driving range, time-consuming energy replenishment, and the difficulty of making routing decisions under dynamic traffic and load-dependent energy consumption. Addressing these challenges is essential for improving the practicality and reliability of EV-based freight transportation.

This thesis investigates optimization frameworks for EV routing in urban delivery systems by studying two complementary energy replenishment strategies: modular battery segment swapping and …

Youth Perspectives On Developing A Sustainable Food Future In Sambaa K’E Nwt., Danielle Elizabeth Bayne Ms

Theses and Dissertations (Comprehensive)

Food systems in Northern Indigenous communities are shaped by complex and interconnected social, environmental, economic, and political forces that determine how food is accessed, practiced, and governed. Indigenous food systems are deeply rooted in Land-based practices and relationships that support cultural continuity and intergenerational knowledge transfer. However, these systems have been profoundly disrupted by ongoing colonial structures that restrict access to and devalue Indigenous Knowledge and alter harvesting practices. Climate change further intensifies challenges related to traditional food access by altering wildlife behaviour, shifting seasonal patterns and reducing the safety and reliability of traditional harvesting territories. In response, many Northern …

“My Voice Is Trauma, My Voice Is Healing:” A Feminist, Trauma-Informed Embodied Study On The Impact Of Gender-Based Violence In Classical Music Communities, Sarah Pearson

Theses and Dissertations (Comprehensive)

This Social Work doctoral dissertation explores the impact of gender-based violence (GBV) in classical music communities on survivor-artists. This is an intersectional feminist, trauma-informed, embodied study that draws on these three theoretical concepts to conceive of classical music as an institution of both colonial patriarchal power and a site of spirituality and meaning-making. The issue of systemic GBV in the performing arts has been a focus of headline news and sensational celebrity stories in the last decade following the MeToo hashtag and is slowly gaining some attention in academic research.

For this qualitative study, the sample consisted of 14 participants …

An Examination Of Speech Motor Control And Auditory Processing In Attention Deficit Hyperactivity Disorder (Adhd), Rita Bishai

Theses and Dissertations (Comprehensive)

Fluent speech production is achieved through a relative weighting of feedback and feedforward motor control systems. These systems are thought to be responsible for the online correction of vocal errors and initiating speech, respectively. The relative weighting of these motor control systems has been shown to differ under conditions of high attentional load and across individual differences in sensory acuity. However, research has yet to examine speech motor control in a population with clinical attentional and sensory processing differences, such as those with Attention-Deficit Hyperactivity Disorder (ADHD). The studies in this thesis aimed to examine how ADHD traits relate to …

Is Prosocial Behavior A Unique Correlate Of Academic Success In Emerging Adulthood?, Jacqueline Di Biase

Theses and Dissertations (Comprehensive)

Prior developmental research has frequently linked prosocial behavior to stronger academic functioning during childhood and adolescence (Cruz et al., 2024; Gerbino et al., 2018; Oberle et al., 2022), yet its relevance to academic success in emerging adulthood remains unclear. Guided by a Positive Youth Development (PYD) framework, the present study sought to address gaps in emerging adulthood research by examining the academic relevance of prosocial behavior while accounting for influential developmental assets and testing its independent contribution to academic achievement. Undergraduate students (N = 501) completed a cross-sectional self-report survey assessing prosocial behavior, self-control, dutifulness, sociability, and cumulative grade …

The Inward Gaze: Byung-Chul Han's Achievement-Subjectivity In David Foster Wallace's Short Fiction, Ivan Marquez

All Student Theses and Dissertations

David Foster Wallace stated that the aim of his fiction and art was to reflect what it meant to be alive and form a relationship with the reader. In "E Unibus Plurum", Wallace posited that the tenets of Post-Modern fiction were once used to criticize the hypocrisies of the 1950's and 60's American had been subsumed by television and were no longer effective tools of criticism. Wallace argues for a move away from irony and stunt pilotry of postmodern fiction towards a fiction which espoused "single entendre values" (Wallace 192). While Wallace advocated for a return to more traditional story-telling, …

Satizabal, Luis J. Mena, Joseph H. Lee, Joseph D. Terwilliger, Eron Manusov

School of Medicine Publications

Background: Although high blood pressure (BP) level and variability are associated with Alzheimer's Disease (AD), their relationship with cortical thickness in brain regions that are associated with AD is unclear. Furthermore, the role of 24-hour BP has not been examined. We investigated the associations of office and ambulatory BP measures with cortical thickness in brain regions implicated in AD.

Methods: We performed a cross sectional analysis of 304 participants without dementia from a population-based study with office and 24-hour BP and magnetic resonance imaging (MRI) data. We considered cortical thickness values derived from 10 regions throughout the frontal, parietal, and …

Spinning-Induced Exertional Rhabdomyolysis Without Acute Kidney Injury, Yolanda V. Gutierrez, Ronald Shaju, Alyssa L. Sepulveda, Joaquin Rivera, Aamir Ahmad

School of Medicine Publications

Rhabdomyolysis is a condition with a myriad of causes, including both traumatic and non-traumatic. Traumatic conditions are observed in crush injuries, compartment syndrome, and fractures, while non-traumatic rhabdomyolysis is commonly seen due to exertional heat stroke, extreme physical exercise, and dehydration. This case report explores two cases of extreme non-traumatic rhabdomyolysis caused by indoor cycling, also known as spinning. A common complication of severe rhabdomyolysis is acute kidney injury (AKI), which increases the risk of renal failure. Rapid interventions such as aggressive intravenous fluids are necessary to prevent kidney function loss. In this case report, two sisters, on two separate …

Faculty, Staff and Students Publications

Introduction: Hispanic/Latino (H/L) adults are more likely than non-Hispanic White individuals to have Alzheimer's disease (AD), yet fewer than one in five H/L adults has apolipoprotein E (APOE) Ɛ4, underscoring gaps in understanding genetic risk across H/L heritage groups. H/L adults remain underrepresented in AD research that uses genetic data for participant stratification. To inform culturally appropriate educational materials for 16 million U.S. Spanish speakers, we identified culturally salient words Spanish-preferring H/L adults use to describe AD and genetic testing beyond APOE.

Methods: Community-residing, Spanish-preferring Mexican/Mexican American adults (n = 14) completed freelisting interviews, a method eliciting …

Fur-Ever In Memory: College Student Grief And Coping After Pet Loss, Rohit Paruchuri

College of Graduate Studies: Theses & Dissertations

Pet loss is a significant yet often overlooked form of bereavement, particularly among college students who are navigating emerging adulthood. Pets play an important role serving as a source of emotional support and are often viewed as family members; however, grief following pet loss is a type of disenfranchised grief, meaning it is not accepted by the society as something significant and often overlooked when compared to grief following human loss (Spain et al., 2019). Research suggests that grief following pet loss can mirror responses to human loss including sadness, guilt, loneliness, and disruption of daily routines (Eckerd et al., …

Effects Of The Menstrual Cycle Phase On Rpe, And Symptom Characteristics In Pre-Professional Female Soccer Players, Emily Potts

College of Graduate Studies: Theses & Dissertations

Hormonal fluctuations across the distinct phases of the menstrual cycle have been shown to influence physiological and psychological responses to exercise, with some evidence suggesting phase-dependent changes in symptom presentation and ratings of perceived exertion (RPE); however, findings remain inconsistent, and few studies have examined these relationships across an entire competitive season in female soccer players. The purpose of this study was to examine changes in RPE and menstrual symptoms across cycle phases, as well as the relationships between RPE and symptom reporting in pre-professional female soccer players. A total of 22 female soccer players (age 22± 1.85) were recruited …

Vibrio In Oysters: Exploring The Impact Of Harvesting Practices, Samin Yasar

College of Graduate Studies: Theses & Dissertations

The rapid growth of oyster aquaculture in the Southeastern United States necessitates the validation of post-harvest processing strategies to mitigate the risk of Vibrio spp. infection. This study investigated the efficiency of three cooling methods - Direct Ice Burial, Indirect Ice Cooling, and Ambient Control, on the prevalence and abundance of V. cholerae, V. parahaemolyticus, and V. vulnificus in cultured oysters (Crassostrea virginica) harvested in Georgia. Additionally, the study examined the safety of two different re-submersion periods for oyster safety.

Internal temperature profiles confirmed that while Direct Ice Burial achieved the most rapid cooling (< 10° C in 7.3 ± 1.2 min), the Indirect Ice Cooling protocol successfully reached the safety threshold in 73.7 ± 17.2 min, well within the 2-hour regulatory window. Microbiological analysis (N = 270) revealed that V. …
