The Body’S “Why?”: Therapists’ Embodied Approaches To Meaning-Making In Trauma And Complex Ptsd, Tanya D. Rock

Theses and Dissertations (Comprehensive)

The challenge of finding meaning in trauma is one that has inspired conversations in psychotherapeutic circles as well as amongst theologians and philosophers. Finding meaning following trauma has been positively associated with growth following the traumatic incident and has been labelled as critical to the progression of healing (Herman, 1992). This study aims to examine the role therapists play in meaning-making with clients who have experienced trauma. The research question is “how do therapists handle meaning of life challenges with traumatized clients?” Ten experienced therapists participated in this qualitative, phenomenological study. Key findings included common therapist responses to client’s “why?” …

The Experiences Of Mothering With An Intimate Partner Violence-Related Brain Injury, Emily L. Sebben Miss

Theses and Dissertations (Comprehensive)

One in three Canadian women will experience intimate partner violence (IPV) in their lifetime, and 75% of them have a probable brain injury (BI) (Haag et al., 2022). Despite the recent growth of IPV-BI research, many survivors remain undiagnosed and many aspects remain unexplored. The experiences of being a mother with an IPV-related BI has been left untold. These gaps leave frontline workers with little guidance in supporting survivors who are specifically mothers. This research reports on a qualitative study exploring the lived experiences of mothering with an IPV-BI. The study uses a constructivist worldview and hermeneutic phenomenology to amplify …

Theses and Dissertations (Comprehensive)

“Just Checking”: Racial Profiling and the Criminalization of Black Students at Post-Secondary Institutions

This dissertation examined the experiences of Black students who came into contact with campus security at five universities and one college in Ontario, Canada. Critical race theory and methodology, and qualitative research design amplified the voices of 17 participants who shared stories of racial profiling marked by racialization, criminalization, surveillance, and the normalized scrutiny of Black life. These experiences are legitimized by post-secondary institutions that are actively reproducing the very racism they are often celebrated for interrogating by allowing a culture of anti-Black racism to exist with …

South-South Migration: Examining The Links Between Food Security And Migration From Ghana To Qatar, Bernard Owusu

Theses and Dissertations (Comprehensive)

This dissertation contributes to the migration-development literature by integrating food security into the analysis of South-South migration. While migration and development have been extensively studied, the connection between migration and food security remains underexplored, particularly in South-South migration contexts. The dissertation highlights the role of migration as both a coping strategy for food insecurity and a source of vulnerability for migrants in the specific context of temporary labour migration between Ghana and Qatar. Addressing this gap, the research examines how migration decisions are influenced by food insecurity in Ghana, the food security challenges faced by Ghanaian migrants in Qatar, and …

“It Is Tiny And It Is Everything”: Exploring The Effects Of Arts-Integrated Gardening On Experiences Of Ecological Grief Through Autoethnographic Research, Christina Kingsbury

Theses and Dissertations (Comprehensive)

This study explores how arts-integrated gardening affects experiences of ecological grief through autoethnography and draws on my personal experiences as a survivor of environmentally linked cancer and artist working with gardens through social practice. My research builds on two areas of emergent scholarship—investigations of ecological grief and gardens as sites for social work practice—to explore how social work may address ecological grief through arts-integrated gardening. I use a quilting autoethnography as a method of inquiry to foreground my subjective knowledge and analyze it through intersectional feminist, disability and decolonizing theories. By incorporating narrative analysis and arts-based inquiry—writing in place, poetic …

Creativity, Fame And Power: A Critical Political Economy Of Social Media Comedy Skit In Nigeria, Idowu Badmus

Theses and Dissertations (Comprehensive)

This study explores social media comedy skits in Nigeria as a novel type of creativity that is both an economic and cultural activity with political and social implications within the context of the rapidly expanding global ecosystem of online content creation. Academic interest in social media comedy skits has grown as a result of their emergence as a popular culture within Nigeria's entertainment landscape. However, most research has focused on understanding this form of humour through its positive societal correlates. Hence, within the notion of industrialization of culture, which suggests that various methods of financing and arranging communication resources have …

Npr1 As A Temperature-Sensitive Regulator Of Pipecolic Acid-Mediated Plant Systemic Immunity, Spencer Tout

Theses and Dissertations (Comprehensive)

Healthy plant development requires balancing both abiotic (e.g. climate) and biotic (e.g. pathogen) challenges, which intercept important signaling pathways in plants. For example, climate change-associated elevated temperature can negatively modulate various aspects of plant immunity, including the production of central immune signals salicylic acid (SA) and N-hydroxypipecolic acid (NHP). Since SA and NHP signaling both require the master immune co-activator protein NON-EXPRESSOR OF PATHOGENESIS-RELATED GENES 1 (NPR1), it is important to investigate NPR1 as a potentially temperature-regulated molecular hub. Although the NPR1 gene is not transcriptionally downregulated at elevated temperatures (28° C vs. 23° C), little is known about …

Exploring The Salinity Tolerance Of Zooplankton Communities On The Great Plains, Abbeneet Binning Bath, Derek Gray

Theses and Dissertations (Comprehensive)

Palaeoecological data shows fluctuating salinity levels in lakes across the Great Plains due to alternating wet and dry periods over the last two millennia. Droughts caused by this natural variation may be exacerbated by anthropogenic climate change, as the Great Plains are expected to become drier over the coming decades. As conditions become drier, the evaporation of water will increase the salinity of lakes across the region. Increases in salinity may significantly impact biodiversity, including important members of lake food webs such as zooplankton. Due to the region's history of alternating wet and dry periods, zooplankton may have adapted to …

Grief On The Margins: The Death Of A Family Member To Substance Use, Adair Shaw

Theses and Dissertations (Comprehensive)

Despite Canada's high death rates from substance use, there is limited research on the sociopsychological impact on families, who often face stigma and disenfranchised grief. This study explores how family members make meaning of a substance-related death. Through qualitative inquiry, eleven family members were interviewed on their experience of grief from substance death. The imprint of losing a family member to mental illness and substance use is fraught with intergenerational grief, ambiguity, prolonged mental-emotional distress, and relationship challenges. Substance death was also associated with stigma, social withdrawal, and shame for many participants. However, grievers reconstructed the socially prescribed negative perceptions …

Moral Identity: From Theory To Research, Jean Paul Lefebvre

Theses and Dissertations (Comprehensive)

Moral identity, often defined as the importance or centrality of moral values to a person’s sense of self, has long been understood to play an important role in moral functioning. However, critical gaps remain regarding its development, cross-context stability, and behavioural significance. This dissertation addresses these gaps in three empirical studies, providing new insights into the nature and function of moral identity across the lifespan and in daily life.

The first study (Chapter 2) explores developmental trends in moral identity, testing predictions from moral identity goal theory (Krettenauer, 2022). Using a cross-sectional sample spanning adolescence to old age, the study …

Art/Place Making In A Settler Colonial Context: A Critical Place Inquiry On The Haldimand Tract/Kitchener-Waterloo From A White Settler Perspective, Haley Sheppard

Theses and Dissertations (Comprehensive)

Although critical place scholars implicate artists in settler colonial processes of placemaking, there is little information on how white settler artists (WSAs) might use their creative practice to support practices of accountability and solidarity with Indigenous resurgence. This research responds to this gap by investigating the creative practices of WSAs located on the Haldimand Tract/in Kitchener-Waterloo (KW), and how they might approach critical, contextual practices in their creative work. A critical place inquiry was combined with ethnographic research principles and a transformative critical research paradigm. Six WSAs participated in mobile interviews, which took place in a location significant to them. …

Evaluation Of The Dnazyme Gr5 For The Determination Of Lead Speciation In Natural Waters, Gaganprit Gill

Theses and Dissertations (Comprehensive)

This thesis explores the development and application of a DNAzyme-based biosensor designed to detect labile metal species in environmental samples. Real time and on-site monitoring of labile metal fractions would make a valuable contribution to environmental management, as these fractions are the most bioavailable and pose significant toxicity risks to aquatic organisms. Conventional methods for detecting labile metals, while effective, are often burdened by high costs, complexity, and lengthy processing times, making them less ideal for rapid and widespread environmental assessments.

The first manuscript of this thesis (chapter 2) establishes the fundamental capabilities of the Pb²⁺-specific DNAzyme GR5 …

Northern ecosystems are experiencing a period of rapid and unprecedented change, with implications for species distributions, mammal community dynamics, and habitat associations. Understanding the ecological processes that shape species distributions is crucial for developing effective conservation strategies that can adapt to such change. This study examines drivers of barren-ground caribou occurrence, a species of cultural and ecological significance, across Thaıdene Nëné Indigenous Protected Area, an ecologically intact landscape of high habitat heterogeneity straddling the treeline of the Northwest Territories. I use spatial and temporal variation in caribou detections generated by camera traps to test the relative importance of apparent competition, …

Uncertainty And Strategy In Fair Allocation Of Indivisible Items, Fahimeh Ziaei

Theses and Dissertations (Comprehensive)

In studies of collective decision-making, the problem of allocating indivisible items fairly and efficiently is widely acknowledged as particularly challenging. Our study assesses various algorithms for finding balanced allocations based on their ability to achieve desirable properties such as envy-freeness, Pareto-optimality, maximin, maximum Borda sum, and Borda maximin.

Two players with additive preferences allocate an even number of indivisible items, given only each other's strict preference ordering. The algorithms under study include both naive and sophisticated versions of Alternating selection, bottom-up Alternating selection (or Alternating rejection), Zigzag selection, bottom-up Zigzag alternation, and fallback bargaining. The results suggest that fallback bargaining, …

Exploring The Interconnections Between Mitochondrial Carrier Proteins Involved In Energy Transfer: The Case Of Uncouplig Proteins 2 And 4, Adenine Nucleotide Translocase, And Phosphate Translocase, Marzieh Tabefam

Theses and Dissertations (Comprehensive)

Mitochondrial carrier (MC) proteins play an essential role in cellular energy metabolism by mediating the transport of solutes and protons across the mitochondrial inner membrane (MIM). This thesis explores the structural and functional characteristics of three groups of MC proteins—Uncoupling Proteins (UCPs), Adenine Nucleotide Translocase (ANT), and Phosphate Translocase (P_iT)—to elucidate their individual and interrelated cooperative roles in mitochondrial proton transport and energy regulation.

The study develops and applies novel methodologies for the overexpression, purification, and reconstitution of MC proteins into model lipid bilayers mimicking the native mitochondrial inner membrane environment. These methods ensure proteins maintain their native-like …

Abstract

Around the globe, there has been a significant focus on ensuring youth receive sufficient education and training in Science, Technology, Engineering, and Math (STEM) domains. Education reforms often begin with educators, who are responsible for effectively implementing curriculum changes. However, in Canada, although STEM education reform is underway, teacher education and professional learning (PL) and development may not have kept pace, potentially leaving some teachers feeling unprepared to integrate these changes confidently and effectively. This dissertation introduces two studies that investigate pre-service teachers’ readiness to teach STEM domains in the classroom, as well as the impact of a PL …

Structural Insights Into Peptidoglycan O-Acetylation In Gram-Negative Bacteria, Tyler Malloch

Theses and Dissertations (Comprehensive)

The Centres for Disease Control has acknowledged that we are entering a post-antibiotic era, where increasing numbers of bacterial pathogens are becoming resistant to known antibiotics. One of the most successfully targeted features of bacteria is also the main component of the cell wall, peptidoglycan (PG). PG is a heteropolymer of alternating sugar residues, namely N-acetylmuramic acid (MurNAc) and N-acetylglucosamine (GlcNAc) which are joined together by b-(1,4)-glycosidic bonds and crosslinked via stem peptide chains. PG is a target, readily lysed by exogenous and endogenous autolysins, such as lysozyme and lytic transglycosylase, respectively. This event leads to cell death …

Influence Of Temperature On Tfm Tolerance In Lake Sturgeon, Emily Bouffard

Theses and Dissertations (Comprehensive)

The lampricide, 3-trifluoromethyl-4-nitrophenol (TFM), has been used to successfully control invasive sea lamprey (Petromyzon marinus) in the Laurentian Great Lakes for over 50 years. TFM’s effectiveness is due to the relatively low capacity of sea lamprey to detoxify TFM. Water temperature has been shown to increase TFM tolerance in larval sea lamprey. However, the effects of temperature on TFM sensitivity in non-target species such as the endangered lake sturgeon (Acipenser fulvescens) are poorly understood, particularly during their early life stages. To determine how temperature affected TFM sensitivity, age 1-year-plus (1+) lake sturgeon acclimated to 8, 16, …

Impact Of Membrane Lipid Composition On The Structure And Function Of Uncoupling Proteins 1 And 2 From Arabidopsis Thaliana (Atucp1 And Atucp2), Elizabeth Silva

Theses and Dissertations (Comprehensive)

A proton gradient across the inner mitochondrial membrane (IMM) is required for the synthesis of adenosine triphosphate (ATP) via ATP synthase. In other words, generation of the proton gradient is coupled to the synthesis of ATP. Interestingly, uncoupling proteins (UCPs), also located in the IMM, dissipate the proton gradient, meaning that the gradient is not efficiently used for the production of ATP.¹ The mechanism of proton transport activity of UCPs has been hypothesized and widely debated for the past 20 years to also reduce oxidative stress by reducing the production of reactive oxygen species (ROS).² The majority of …

International Students Practicing Their Wellbeing: Social Connections And Use Of Professional Mental Health Services, Lal Ruby Atesoglu

Theses and Dissertations (Comprehensive)

International students are a growing group of immigrants in Canada, and in particular in Ontario. Literature has consistently showed that international students experience unique mental health challenges, with reasons ranging from uncertainty about the future to having to cultivate social networks from scratch. Despite these stressors, they access professional mental health services at a lower rate than domestic students. Research has also shown that international students turn to their social connections to address their mental health concerns frequently. The aim of this study is to explore how international students utilize professional mental health services as well as their social connections …

Environmental, Governance, And Bibliometric Research On Corporate Tax Avoidance, Harjot S. Mehmi

Theses and Dissertations (Comprehensive)

This dissertation is composed of a literature review and three essays positioned in the corporate tax avoidance (CTA) space. The literature review summarizes the relationship between CTA and environmental, social, and governance (ESG) factors. Although there are mixed findings within each of the E-S-G categories in the CTA literature, in general, better environmental circumstances are negatively associated with CTA, social performance displays an inverse relationship with CTA, and governance factors also display an inverse relationship with CTA. The first essay is an empirical archival investigation of the relationship between CTA and an environmental factor – the risk of environmental hazards …

Fallow Fields Or Fertile Ground: Analysing Food Governance In A Changing World, Johanna L. Wilkes

Theses and Dissertations (Comprehensive)

Our food systems are failing us. In particular, industrial food systems fail to deliver healthy, adequate food to billions of people (FAO et al. 2019; FAO et al. 2024) and have led to increased instances of mental health crises for farmers (Jones-Bitton 2019; Younker & Radunovich 2021). In addition, industrial food systems contribute to the devastating impacts of a warming climate (IPCC 2021), biodiversity loss (WWF 2021), and soil erosion (Wise 2019; Badreldin and Lobb 2023) worldwide. Yet, little structural change has occurred in the way agriculture is governed and the problems created by industrial agriculture are becoming increasingly entrenched. …

Lichen It: Optimizing Post-Fire Caribou Lichen Transplantation And Assessment, Elise Brown-Dussault

Theses and Dissertations (Comprehensive)

Caribou lichen species are common in mid- to late-seral boreal forests, serving as an important winter diet staple for boreal woodland caribou. However, as climate change causes boreal wildfires to increase in size, severity, and frequency, available tracts of mature forest are decreasing, diminishing the extent of mature caribou lichen stands. Caribou lichens reproduce vegetatively, so bigger and more severe fires could exacerbate their dispersal limitations, potentially extending the timeline for caribou lichen stand recovery beyond 80 years. Trials have shown that “transplanting” caribou lichen fragments into disturbed areas can lead to the establishment of caribou lichen mats; as such, …

Individual Differences In The Evolution Of Strategies In Spatial Problem Solving, Jade T. Moussa

Theses and Dissertations (Comprehensive)

Navigating the world requires a strategy – you must choose which information to attend to and use from a wealth of internal and external cues in order to find your way. People have biases to prioritize some kinds of information over other. This is, in part, determined by individual differences in cognitive abilities. For instance, some individuals have a bias for spatial information that leads them to not only solve spatial tasks faster but are also more likely to use spatial information to solve tasks even when other information is available. However, peoples' navigation strategies also evolve over time. Although …

Thermokarst Can Stimulate Tall Shrub Productivity And Plant-Soil Feedbacks In The Low-Arctic Tundra, Claire O'Brien

Theses and Dissertations (Comprehensive)

Warming temperatures are exacerbating permafrost thaw disturbances in the Arctic. Permafrost thaw disturbances are facilitating tall, deciduous shrub expansion. However, potential productivity differences between shrubs that colonize disturbed areas and those in undisturbed tundra remain understudied. More productive shrubs optimize for fast growth over leaf longevity, meaning they may produce more abundant and higher quality litter which could accelerate decomposition rates and lead to faster nutrient cycling. Faster nutrient cycling could create a positive feedback loop between shrubs and soil, maintaining greater ecosystem productivity. I measured in situ soil characteristics and physiological and structural shrub functional traits for green alder …

Timing Of Migration And Seasonal Movements Of Arctic Grayling (Thymallus Arcticus) In Relation To Water Temperature In The Kakisa River And Upper Mackenzie River, Nwt: Results From An Acoustic Telemetry Study., Levi Snook

Theses and Dissertations (Comprehensive)

Arctic grayling (Thymallus arcticus) are a cold-water salmonid that inhabit waterbodies throughout the circumpolar regions of the northern hemisphere. In the last decade, Ka'a'gee Tu First Nation members as well as local sport fishers, have observed lower catches of Arctic grayling during their annual spawning run in the Kakisa River, NWT. Many potential causes of this decline have been hypothesized including climate change and over harvesting. Outside of the general annual spawning activity in the headwaters of the Kakisa River, the ecology of the population, including post-spawn habitat use and migratory patterns, remained understudied. To address these knowledge gaps, acoustic …

Multi-Lingual And Cross-Domain Frontiers In Machine-Generated Content Detection, Gurunameh Singh Chhatwal

Theses and Dissertations (Comprehensive)

The rapid advancement of generative artificial intelligence, particularly Large Language Models (LLMs) such as GPT-4 and their multilingual capabilities, has significantly blurred the distinction between human-authored and machine-generated content. This technological evolution introduces critical challenges concerning the detection and attribution of textual authenticity and authorship, exacerbating societal issues like misinformation proliferation and compromising academic and professional integrity. Traditional detection methodologies, predominantly monolingual and heuristic-based, have demonstrated inadequate generalizability and efficacy against the sophisticated, multilingual capabilities of contemporary generative models.

This thesis addresses two major problems arising from these advancements. Firstly, it introduces novel multilingual detection methodologies explicitly designed to differentiate …
