The Echoes Of Heartbreak: Shaping Confidence In Future Relationships Through Metaperceptions Of The Past, Anika P. Patychuk

Theses and Dissertations (Comprehensive)

Romantic relationship dissolution can be deeply destabilizing. Existing research has documented the emotional and psychological consequences of breakups but has rarely examined how these experiences shape subsequent relationship functioning. While breakups often trigger self-protective responses that can inhibit future relationship formation, individuals may also derive valuable relational insights from these experiences. The present research examined whether perceiving past romantic relationships as valuable sources of relational knowledge (epistemically valuable) enhances confidence in future romantic pursuits. I propose that perceiving past relationships as high (vs. low) in epistemic value encourages confidence in future romantic pursuits. I tested this hypothesis in three experimental …

An Antiviral Response Induced By Dsrna Against Vesicular Stomatitis Virus And Bovine Respiratory Syncytial Virus In Bovine Turbinate Cells, Carly Au

Theses and Dissertations (Comprehensive)

Canada is one of the largest beef exporters in the world. Viruses like vesicular stomatitis virus (VSV) and bovine respiratory syncytial virus (BRSV) can negatively impact the cattle industry, and a prophylactic treatment is needed to protect against these viruses. Viruses produce long (L)dsRNA (>30-40bp) during replication that is not found in healthy cells. As such, the innate antiviral immune response, including the RNA interference (dsRNAi) pathway, are stimulated by viral LdsRNA. When low concentrations of LdsRNA are present, the RNAi pathway is triggered resulting in the degradation of viral mRNA of matching sequence, halting specific viral protein production. …

Rapid industrialization and population growth have contributed to a decline in air quality, with particulate matter (PM) posing particular concern. PM originates from both natural and human sources and often contains toxic chemicals and microorganisms, including potential pathogens. Inhalation of PM is linked to respiratory and cardiovascular diseases, underscoring the need to characterize better its chemical and biological composition in understudied region - Waterloo, Ontario, Canada. The present thesis is a culmination of three main parts. Part 1 will describe the use of the dithiothreitol (DTT) assay to quantify the oxidative potential of PM through DTT consumption of redox-active field …

Macroinvertebrate Communities And Food Web Structure In Tundra Streams Are Shaped By Substrate Size And Beaver Impoundments, Mathew K. Mervyn

Theses and Dissertations (Comprehensive)

North American beavers (Castor Canadensis) are expanding their range into the Arctic tundra as climate change drives earlier ice and snowmelt, and increased shrub cover. As ecosystem engineers, beavers build dams that alter water chemistry by creating impoundments within streams, trapping sediment and organic matter, and modifying nutrient cycling. This thesis evaluates how beaver impoundments interact with natural geomorphic variation in tundra streams and how impoundments affect tundra freshwater ecosystems in the western Canadian Arctic.

In Chapter 2, I compared water chemistry and benthic macroinvertebrate (BMI) community composition across 16 stream reaches, including those with and without beaver dams, with …

A Dance Of War Or Love: Applying A Gendered Lens On The Lived Experiences Of Women Social Entrepreneurs In Nigeria, Grace C. Ihejiamaizu

Theses and Dissertations (Comprehensive)

This study explores the lived experiences of Nigerian women social entrepreneurs, using a qualitative methodology rooted in yarning circles, a culturally respectful, relational approach that foregrounds storytelling and co-construction of knowledge. Through this method, the research examines how these women navigate the intersections of gender, culture, power, and purpose within highly patriarchal and institutionally constrained environments.

The findings assert that Nigerian women social entrepreneurs are not static actors driven by fixed motivations, but dynamic changemakers whose goals shift as they gain access to resources, legitimacy, and social capital. The Cycle of Privilege framework helps us understand this evolution as an …

Crime Modeling Using An Integrated Cnn–Lstm Architecture With Embedded Self-Excitation, Pawandeep Kaur

Theses and Dissertations (Comprehensive)

It is often assumed that natural phenomena occur randomly over time. However, careful analysis reveals that these events typically form some series or sequences and exhibit distinctive temporal patterns. These patterns are not exclusive to nature. They also appear in human activities, often studied under the concept of bursty human dynamics. The statistical methods analyzing bursty human dynamics not only capture overall trends or seasonality but also explore how past events influence future ones. It makes the analysis more realistic and the results more closely aligned with reality. Bursty human dynamics can be studied at two levels: the individual level …

Terpenes Mitigate Thc-Induced Working Memory Deficits: Behavioural Evidence Of The Entourage Effect Using A 2-Component Operant Memory Task, Lara Mitchell

Theses and Dissertations (Comprehensive)

Most research on cannabis and cognitive function has focused on delta-9-tetrahydrocannabinol (THC). However, this approach overlooks the complex chemical composition of cannabis products consumed by the public, which often includes cannabidiol (CBD) and various terpenes. These additional constituents may interact with THC to modulate its effects, a phenomenon known as the entourage effect. While this theory has gained traction, experimental evidence for the cognitive impact of terpenes in combination with THC remains limited. This study aimed to assess whether terpenes can mitigate THC-induced cognitive deficits using a 2-Component Operant Memory task. Male Sprague-Dawley rats received intraperitoneal injections of either …

2slgbtq+ Contact As A Vehicle For Promoting Alternative Sexual Scripts Through Exposure To Queer And Trans Ways Of Knowing, Sophie R. Landry

Theses and Dissertations (Comprehensive)

Research on the Traditional Sexual Script (TSS) suggests it can have harmful repercussions, such as sexual violence, gender inequity, and the undermining of communication. My research explores the novel idea that intergroup contact with 2SLGBTQ+ individuals can promote CisHet (cisgender, heterosexual) individuals to value alternative sexual scripts that emphasize communication, authenticity, and equity, and to question the TSS. In Study 1, I found that CisHet people who had more 2SLGBTQ+ contact reported greater concern for consent and were less likely to agree with traditional gender norms relative to those who made less contact. In both Study 2 and Study 3, …

Evaluating The Credibility Of Online Websites: A Digital Information Literacy Program, Emily C. Wood, Kim P. Roberts

Theses and Dissertations (Comprehensive)

The plethora of information currently available via the internet is greater than ever before. Given this, finding credible information is an exceedingly complex task for any information consumer, but especially so for children. Research shows that children have difficulty evaluating the credibility of online information and are more susceptible to believing misinformation compared to adolescents. While a growing body of research addresses children’s internet use, most research focuses on technology safety rather than the evaluation of online information. Several studies have found digital information literacy (DIL) interventions to be successful at increasing critical thinking and awareness of the criteria to …

Exploring The Role Of Collective Narcissism And Ideology In Support For Reparations, Melih Can Sahin

Theses and Dissertations (Comprehensive)

Many societies with colonial histories have begun to grapple with their legacy of historical injustices and their ongoing consequences, leading to national apologies and sometimes consideration of reparations. In this context, it is important to understand the factors enhancing or impeding public support for reparations. This dissertation focused on the role of beliefs (ideology) and identity (collective narcissism) as predictors of support for reparations addressing historical injustices. Drawing from existing research, we expected that those higher in conservatism – and those higher in collective narcissism - would oppose reparations more strongly. We also examined the interaction between ideology and collective …

Nature For All? Assessing Equitable Public Access To National Urban Parks In Canada: A Comparative Analysis, Andrew Tenute

Theses and Dissertations (Comprehensive)

The number of health challenges is rising both globally and in Canada. Research consistently shows that time spent in nature can mitigate some of these health challenges, offering significant mental, physical, and well-being benefits. Parks and protected areas in Canada, including the expansion of the National Urban Park (NUP) program by Parks Canada, provide valuable opportunities for nature-based engagement. However, access to these spaces is unjust, as many individuals face structural, intrapersonal, and interpersonal constraints. While prior studies have explored the motivations and well-being outcomes of women and Black, Indigenous, and People of Colour (BIPOC) individuals, there remains a limited …

Theses and Dissertations (Comprehensive)

Northern Indigenous communities face disproportionate impacts from interconnected challenges related to climate change, food security, health, and cultural preservation, that threaten traditional food systems and practices. While there is a growing recognition of the importance of community-driven solutions, existing frameworks fail to integrate Indigenous values and local priorities effectively. This research addresses this gap by exploring how the Ka’a’gee Tu First Nation (KTFN) is responding to these crises through climate change adaptation efforts focused on food system sustainability as a pathway to self-sufficiency and community well-being. To contribute to these efforts, this dissertation uses Participatory Action Research to facilitate community-driven …

Feeling Blue: The Effects Of Blue Light Exposure On Reproduction And Physiology In Drosophila Melanogaster, Laura Hampel

Theses and Dissertations (Comprehensive)

Blue light, the wavelengths ranging from ~400-500 nm, is emitted from the sun and more recently, by artificial lights including those in technology. In humans, prolonged exposure to blue light has been consistently linked to circadian rhythm disruption and retinal damage, and has also been associated with changes in neurodegeneration, aging, mortality, and oxidative stress in model organisms. This thesis explores the multifaceted effects of blue light exposure through two independent but complementary approaches. An initial rapid review of the current state of knowledge on blue light induced oxidative stress in humans was conducted. This revealed that the most studied …

Theses and Dissertations (Comprehensive)

This dissertation explores the lived experiences of African women refugees from the East and Horn of Africa and Great Lakes (EHAGL) region resettled in Ontario, Canada, with particular focus on the complex intersections of trauma, resilience, and healing within global refugee governance. It asks: How do the gendered and spatial dynamics of refugee protection and Canadian settlement systems sustain structural violence against African women refugees, and how do their transnational experiences challenge and reshape dominant frameworks of care, well-being, and institutional response?

Through a multi-scalar analysis—macro (legal governance frameworks), meso (institutional actors), and micro (women’s narratives)—the study explores how trauma …

Exploring The Experiences Of Racialized Immigrant Mothers In Contributing To Patterns Of Community Life In The Victoria Hills Neighbourhood, Carmel Tatiana Mahdi Miss

Theses and Dissertations (Comprehensive)

The experiences of racialized immigrant mothers are complex, nuanced, and beautiful. Oftentimes, their stories are described in a way that frames women as helpless victims, merely writing about their challenges in the absence of their protagonism. The stories in this thesis suggest that, against the obstacles unique to racialization, motherhood and immigration, mothers are often the primary caretakers of their families and play a significant role in the development of children, while creatively exploring and responding to questions pertinent to community development. They navigate community life in a place different from the one they grew up in – addressing questions …

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. …
