It is well known that pain can heighten sensitivity to stimuli that signal threat in most species. In rodents, exposure to predator odor, such as 2,5-dihydro-2,4,5-trimethylthiazoline (TMT), induces anxiety and alters pain sensitivity. This study explored the effect of predator odor stress on mechanical pain sensitivity in a rat model of acute inflammatory pain induced by suboptimal doses of Complete Freund's Adjuvant (CFA). Male Sprague-Dawley rats were injected intraplantarly with 50% or 25% (v/v) of CFA in the hindpaw and then exposed the next day to 5 minutes of either 10% TMT (synthetic fox urine) or a neutral odor. Both groups showed reduced paw withdrawal thresholds in the von Frey test. However, TMT-exposed rats displayed persistent mechanical hypersensitivity, which never returned to baseline (pre-CFA) levels when compared to CFA-rats exposed to the neutral odor or control rats exposed to TMT. In addition, TMT exposure after CFA induced greater anxiety-like behavior in the elevated plus maze without affecting locomotor activity in the open field or altering learned responses in a backward paired shock-tone conditioning task. Finally, systemic administration of a CCK2 antagonist before exposure to TMT partially rescued the mechanical hypersensitivity in these animals but had little effect on CFA-treated rats exposed to the neutral odor. These results suggest that naturalistic stress can lead to a long-lasting nociceptive sensitization that extends beyond the duration of the initial inflammatory injury. Our findings also highlight the importance of CCK2 signaling as a potential mediator of and therapeutic target for stress-induced pain hypersensitivity.

Food in high medieval England (1066–1315) was central to socialization. It played a key role in social gatherings, both through fasting and feasting. The thesis examines the symbolic and functional roles of food rituals across lay, ecclesiastical, monastic, noble, and royal groups, highlighting the ways in which food served as a means of socialization and a tool for asserting power, prestige, and social norms. This study relies on a rich combination of primary source materials derived from chronicles, histories, visual sources, monastic rules, collections of recipes, courtesy literature, and administrative and legal sources. The theoretical frameworks established by Ledyaev (1997), Wagner (1996), Durkheim (1912), and Berger, Rosenholtz, and Zelditch Jr. (1980) guide this study. It argues that food, through fasting and feasting, was not merely sustenance but an instrument of socialization.

Prevailing rates of sexual violence have necessitated research on sexual consentcommunication to remedy these issues. Research has found that individuals possess sophisticated knowledge of consent, and that discrepancies between people's attitudes and behaviours are resulting in sexual violence and compliance behaviours. The BDSM community–with its greater diversity and effective consent strategies–possess a model of consent that would be valuable in diminishing rates of adverse sexual outcomes. However, differences in consent between BDSM and non-BDSM individuals have not yet been quantified. 1,118 participants completed measures of consent attitudes, behaviours, and consequences. Results demonstrated negligible differences in consent parameters based on BDSM affiliation; however, BDSM role identity yielded large, significant trends. Dominant individuals were found to have less positive consent attitudes, less consent communication and more instances of sexual compliance compared to submissive or switch individuals. These results highlight the strength of cultural norms in dictating beliefs and behaviours.

The traditions of spirituality and meditation have been found to connect to psychological health in the form of increased happiness, empathy, and decreased anxiety. The present study aimed to better understand how these practices might connect to such beneficial outcomes. A sample of 363 undergraduate student participants completed a questionnaire that measured their meditation practice, mindfulness, spirituality, happiness, empathy, and anxiety. Contrary to expectations, meditators and non- meditators did not significantly differ in their psychological health outcomes. These findings have implications for how meditators and non-meditator groups should be differentiated in research. Regarding spirituality, the purpose and meaning and innerness dimensions of the construct significantly predicted happiness and decreased anxiety, while the unified interconnectedness dimension significantly predicted empathy. The transcendence dimension of spirituality did not significantly predict psychological health. This pattern of results has implications for spiritual care interventions that intend to augment psychological health.

This thesis explores the double-bind Indigenous Peoples encounter when pursuing post-secondary education in the field of Indigenous Studies. I argue that Indigenous voices deemed tolerable are incorporated into the commodification of Indigenous thought and experience for the Settler audiences who profit most from post-secondary institutions. My analysis discusses the possibilities for Indigenous Studies to navigate this parasitic relationship and assist Indigenous lives that academia renders unrecognizable. I examine my educational journey and conduct a literature review of the role that Settler Colonialism plays within Indigenous Studies. Through the use of critical self-reflexivity, this thesis employs Haudenosaunee political thought and Indigenous storywork to tell my personal narrative navigating the macro and micro dynamics within the academy that exploits Indigenous student's self-interest to maintain the Settler-Colonial status quo in higher education. I identify strategies to assist academics in conducting ethical research within Indigenous Studies and imagine insurgent education within the Canadian university.

This study examines the lived experiences of refugee students in the Canadian education system and how the barriers they face have influenced their learning and identity. This qualitative study employs critical discourse analysis to bring visibility to the educational experiences of five participants who completed high school in Canada and explores their experiences with resettlement and what would have made their lives better at that time. DisAbility Critical Race Theory informs the researcher on deconstructing and dismantling the deeply entrenched discourses in Canadian schools; to make the implied relationships between language, Western norms, power, whiteness, and race clear. This study is motivated by the researcher's own identity as a newcomer with challenges navigating the Canadian education system, positionalities that have led to the question: Are refugees truly welcome here? Information gathered from this study can support Canadian schools to create just, critically informed, and supportive educational environments for refugee students.

Sexual agency is receiving more attention in sexuality research though its contribution to sexual well-being has yet to be determined. Sexual agency has been theorized as an overarching concept comprised of both internal and external components. Both feelings and behaviours in the sexual domain can be impacted by prevalent culturally prescribed sexual scripts. The present study assessed sexual assertiveness, sexual self-concept, and comfort in sexual communication (i.e., together conceptualized as sexual agency) to determine if greater levels of these indices led to more direct consent communication, more intrinsic motivations for engaging in sex, and more positive sexual evaluations. Analyses were run separately on two samples: a student and community participant pool. Results indicate that greater sexual agency predicts being more intrinsically driven to engage in sex, using more direct consent communication, and reporting more positive evaluations of one's most recent sexual encounter. Gendered analyses reveal that cismen and ciswomen have similar levels of sexual agency, and rate their encounters similarly. Having greater sexual agency was a better predictor of experiencing sexual well-being compared to gender. Implications for policy development and sexual education curriculum reform are discussed, and future research directions are suggested.

Arctic breeding shorebirds are often considered alternate or secondary prey to avian and terrestrial predators that primarily feed on cyclic populations of rodents. Predation risk can strongly influence habitat selection; however, there is limited understanding of how nest placement by shorebirds and subsequent risk of nest predation are affected by spatiotemporal patterns involving the indirect effects of alternate prey on predator activity. I examined nest fates of Whimbrel (Numenius phaeopus) and Dunlin (Calidris alpina) at the southernmost edge of their breeding ranges at Polar Bear Provincial Park, Ontario, using field surveys including direct observations, camera monitors and thermal probes. I used resource selection functions (RSFs) to compare used and available habitat features near shorebird nests. I assessed whether shorebird nest predation was affected by spatial patterns in avian predator activity, habitat, and small mammal alternate prey and annual variation in cyclic small mammal abundance. RSFs confirmed strong habitat selection for graminoid fen habitats with avoidance of tundra heath, presumably to avoid terrestrial predators that may use them as travel corridors. Shorebird nest predation was not affected by the spatial variation in avian predator activity. However, Dunlin nest predation risk was affected by spatial variation in small mammal abundance. Further, the effect was strongest in years consistent with peaks in the small mammal population cycle. These findings highlight the important effects of spatiotemporal variation of alternate prey densities on Arctic-Subarctic food webs, providing insights on the complex relationships affecting shorebird nest success.

Colonization has transformed the landscapes of the American Midwest and compromised the region's resources and ecologies. In response, governments, environmental scientists, and Indigenous nations have undertaken myriad efforts over the past century to restore Midwestern environments. Yet the appropriate goals and techniques for this work have been deeply contested. This thesis explores the scientific, political, and cultural meanings of ecological restoration in the region. Comparison of different forms of restoration reveals the contingency, malleability, and historical pitfalls of restoration knowledge and practices. By framing the pursuit as a problem of scientific, historical, or technical knowledge, practitioners have often neglected the political and cultural ramifications of restoration efforts. At the same time, restoration practices have influenced the intellectual, environmental, and political history of the Midwest in the twentieth century. The efforts of Midwestern scientists and public agencies have advanced wildlife and ecosystem conservation in the region, but have at times exacerbated environmental injustices and inequalities. More recent wild rice conservation efforts by Ojibwe governments demonstrate that, depending on how the framework has been constructed, ecological restoration has served as a tool for reclaiming Indigenous sovereignty as well as a vehicle for settler colonialism.

Small scale farming at the homestead or hobby farm scale provides opportunities for members of the public to visit farms, see livestock, and engage directly with how their food is produced. This scale is often dismissed as or minor importance, yet the biosecurity of larger farms makes these small farms often the only ones that the public can visit. My research explores whether communities want these direct connections with agriculture, and if this provides understanding of the interconnection of farming ecosystems. As a small scale egg producer, I first provide a personal autoethnography of my own operation. I then examine my customers attitudes toward my produce and farm, and analyse interview of other local producers and community members.
