Sex Differences In Inter-Temporal Decision Making And Cortical Thickness Of The Orbitofrontal And Insula In Young Adult Cannabis Users: Evidence From 1111 Subjects, Alan N. Francis, Joan A. Camprodon, Francesca Filbey

School of Medicine Publications

To test for sex differences in the impact of cannabis use on decision-making and brain correlates, we employed cortical thickness (CT) analysis of brain regions involved in intertemporal decision-making namely bilateral orbitofrontal cortex(OFC) and insula in young adult nondependent cannabis-users(CU) and non-users(NU) and their scores on delay discounting task. Neuroimaging analyzes of previously collected data were performed on 608CU and 503NU. CT analysis was performed on MRI images. OFC and insula thickness, scores on the delay discounting test were compared between groups and correlated. Controlling alcohol-use and intra-cranial-volume, CU exhibited sex differences in CT. The bilateral insula was significantly thinner …

Clinical Criteria For Limbic-Predominant Age-Related Tdp-43 Encephalopathy, David A. Wolk, Peter T. Nelson, Liana Apostolova, Konstantinos Arfanakis, Patricia A. Boyle, Cynthia M. Carlsson, Nick Corriveau-Lecavalier, Penny Dacks, Bradford C. Dickerson, Gladys E. Maestre

School of Medicine Publications

Limbic predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) is highly prevalent in late life and a common co-pathology with Alzheimer's disease neuropathologic change (ADNC). LATE-NC is a slowly progressive, amnestic clinical syndrome. Alternatively, when present with ADNC, LATE-NC is associated with a more rapid course. With the emergence of anti-amyloid therapeutics, discrimination of LATE-NC from ADNC is critical and will lead to greater clinical recognition of amnestic patients without ADNC. Furthermore, co-pathology with LATE-NC may influence outcomes of these therapeutics. Thus there is a need to identify patients during life with likely LATE-NC. We propose criteria for clinical diagnosis of …

Ontario bylaw officers are at the forefront of the province’s response, enforcing lockdown rules to ensure community safety. This research is imperative in understanding how bylaw officers maintain their roles in municipal enforcement, while enforcing rapidly shifting COVID-19 regulations and moving forward into a post-lockdown climate. The research focuses on identifying and understanding the demands and resources that currently typify bylaw officers working in Southern Ontario. It further examines how the COVID-19 …

Capital Structure Models And Contingent Convertible Securities, Di Meng

Theses and Dissertations (Comprehensive)

The 2007-09 financial crisis showed financial institutions are vulnerable during distressed times. As an alternative resolution to a government bail-out, contingent convertible securities (contingent capital or CoCos) were proposed by various researchers. CoCo is a hybrid capital security that converts from a bond to common equity when a pre-determined event occurs. The loss absorption mechanism of CoCo is essential to the financial health of a bank during a crisis as it provides an instant capital infusion when public capital is difficult to access.

In this thesis, we first implement a methodology to calibrate capital structure models for large Canadian banks. …

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 …

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 …

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 …

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 …

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 …

From Cuffs To Compassion: The Impact Of Relational Policing De-Escalation Approaches On Public Perceptions Of Safety, Satisfaction, Procedural Justice, And Police Legitimacy., Brook Snider

Theses and Dissertations (Comprehensive)

Academics, policy makers, and the public have called for the prioritization of de- escalation training and use in public-police interactions to reduce police use of force (PUoF) (e.g., Dubé, 2016; Iacobucci, 2014; Todak, 2017; Wortley et al., 2021). In response to various calls to action, the Ministry of the Solicitor General launched the Ontario Public-Police Interactions Training Aid Framework in 2023, which emphasizes the importance of utilizing a relational policing approach in public-police interactions (see Lavoie et al., 2022). However, despite changes in police training frameworks, relatively little is known about PUoF in Canada (Wortley et al., 2021), with similarly …

Theses and Dissertations (Comprehensive)

This dissertation examines Indian international student migration to Canada focusing on students from the north Indian state of Punjab, a region with extensive history of migration and transnational social ties to Canada. Punjab has historically been the predominant sending region within India to Canada, and which continues to dominate in the present phase of international student migration to Canada. The pursuit of higher education has become particularly popular in Punjab. Furthermore, Canada has recently emerged as a significant international study destination following its international education strategy aimed to attract and increase the number of international students. The study employs qualitative …

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, …

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. …

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 …

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 …

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 …

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, …

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. …

To Encounter The Other? How Journalists Make Catholic Faith-Based Organizations In Mexico And Russia (In)Visible, Xochiquetzal Luna Morales

Theses and Dissertations (Comprehensive)

Catholic Faith-Based Organizations (CFBOs) in Mexico and Russia are unique entities of study and comparison to understand the power dynamics between majority/minority institutional religions and their media representation. Although both countries recognize their religious diversity, Catholicism is still the major religion in Mexico, not only because of its large number of adherents but also its significant cultural and political capital. In contrast, in Russia, Catholicism is considered a minority religion and is often viewed as foreign to Russian values and traditions. These conditions influence how CFBOs have been featured in the news media in both countries. However, no single factors …

What Is Success? How Peer Support Workers In Ontario See Addiction & Recovery, Ngaire Rasmussen

Theses and Dissertations (Comprehensive)

The drug crisis in Canada has high mortality rates, especially in remote and rural communities, but there are significant barriers to accessing healthcare to which peer support may represent a partial solution, (Eddie et al., 2019; Englander et al., 2020; The Government of Canada, 2023; Kourgiantakis et al., 2023; Lavalley et al., 2020; Lennox et al., 202; Russell et al., 2021). Research how peer support workers define success in their work with adults experiencing addiction in Ontario, Canada is lacking, but important to understanding the crisis and implementing peer programs. Grounded in Marxist theory, the following exploratory research investigated the …

Exploring Canadian Social Work Students' Aphobic Attitudes: The Role Of Knowledge About Asexuality And Asexual People, Brianna V. Azzoparde

Theses and Dissertations (Comprehensive)

Aphobic attitudes are negative biases and prejudices against asexual individuals that can contribute to aphobic discrimination. While the Canadian Social Work Code of Ethics states that social workers should not discriminate and should provide culturally responsive services to marginalized populations, individually held aphobic attitudes have the potential to diminish one’s ability to provide culturally responsive services to asexual people. This national study examined aphobic attitudes among 326 Canadian social work students, exploring the relationship between knowledge about asexuality and aphobic attitudes, including controlling for demographic factors, social contact with asexuals, and social attitudes that previous research has identified as being …

Student Engagement And Resistance: Exploring The Stories Of African Canadian Girls In High Schools In Southwestern Ontario, Esther R. Hayford

Theses and Dissertations (Comprehensive)

Abstract

Student resistance is complex and has been described in existing literature as self defeatist, reactionary, conformist, transformational or strategic. Some Black students respond to interactions considered oppressive at school by engaging in a variety of resistive actions. Existing scholarship about Black student resistance in the US and Canada are largely framed within deficit frameworks with limited focus on Transformational Student Resistance. Research that focuses on transformational student resistance by Black girls, how schools respond, and how some resistive behaviours can be considered opportunities for change, is limited. While a diverse community, studies about Black girls often portray them as …

Marine And Freshwater Habitats Used By Sympatric Anadromous Arctic Char (Salvelinus Alpinus) And Dolly Varden (S. Malma Malma) In The Central Canadian Arctic, Simon W. Depasquale Mr.

Theses and Dissertations (Comprehensive)

Two closely related but distinct species of char, Arctic Char (Salvelinus alpinus) and Dolly Varden (S. malma), are critically important to the food security and culture of Indigenous peoples in northern North America. Subsistence Inuit fishers in Kugluktuk, NU, Canada, have noticed changes in the timing and locations of their catches of char in the past ~ 10 years. In response, an ongoing partnered research program between the Kugluktuk Hunters and Trappers Organization (HTO) and scientists was formed to study Arctic Char and northern form Dolly Varden (S. malma malma). Char research near Kugluktuk presents a unique opportunity to further …

Characterizing The Targeting Of Toc159 Receptors To The Chloroplast Outer Envelope Membrane And Their Role In The Assembly Of Distinct Toc Complexes, Michael Fish

Theses and Dissertations (Comprehensive)

Global agriculture and food security face challenges from climate change, population growth, and other human-driven pressures. Enhancing our understanding of plant biology, particularly chloroplast function, is critical for improving crop yield and stress resilience. As the sites of photosynthesis and key regulators of plant responses to environmental cues, chloroplasts depend on the precise import of thousands of nuclear-encoded proteins to maintain their biogenesis and function. While much is known about the core translocon components in the chloroplast outer envelope membrane that form the TOC complex, the mechanisms underlying their targeting, assembly, and regulation remain incompletely understood.

Plastids, including chloroplasts, evolved …

Battling Oppression And Crafting New Identities: Case Study Of The Woman, Life, Freedom Movement In Canada, Kiana Habibagahi

Theses and Dissertations (Comprehensive)

Iran’s Woman, Life, Freedom movement began in 2022, and Canada’s Iranian diaspora– the second-largest globally–continues to mobilise advocacy initiatives in its support. However, no studies have examined the movement’s implications on identity individually or collectively. These gaps fail to recognise the experiences of Iranian peoples in Canada who care deeply for the movement and have been historically marginalised. As such, using a qualitative and arts-based method, my project facilitates the retelling of experiences of young adult advocates (n = 4) in the Woman, Life, Freedom movement. Specifically, I inquired about the perceived development of their collective identities as advocates, along …
