Sexual health education (SHE), specifically formal SHE, can play a key role in offering individuals the necessary information, motivation, and skills needed to maintain and improve their sexual health. This study used a survey-based approach to explore the relationship between Canadians' (N = 675) perceived quality of SHE and their feelings and behaviours related to sexual consent and communication, at two time points. This study was informed by two theoretical approaches: sexual script theory and the theory of planned behaviour. Hierarchical regressions were employed to determine how much the participants' education and demographics explained their attitudes, feelings, and behaviours. Perceived quality of SHE predicted consent feelings, and consent and communication behaviours during participants' first sexual experience, and only verbal communication during their most recent sexual experience. This research has furthered our understanding of the long-term impacts of SHE on feelings and behaviours related to sexual consent and communication.

This study examines the intersection between nuclear energy in Ontario, Canada, with popular forces acting upon it between the 1940s and the mid-1980s. It finds that nuclear energy was the target of changing epistemology as society shifted to a post-modern framework in its perception of technology. Technology was irreparably associated with potential encroaching governmental Technocracy. Nuclear was additionally impacted by a societal misunderstanding of the engineering design philosophy, success through failure, as a negative aspect. These factors then combined with the common psychological phenomenon of affective heuristics to produce a society that was fundamentally opposed to nuclear energy on intellectual principles, safety principles, and base psychological principles. It is the finding of this paper that these factors almost assuredly contributed to the cancellations of and shift away from nuclear power in Ontario. This study offers a rebuttal to the overarching popular misconceptions of, and apprehension toward, nuclear energy.

Institutional claims of university-community engagement in support of the public good and planning for teaching, learning, and research have largely remained in the realm of rhetoric. This thesis analyzes the 2019-2021 Trent University Lands and Nature Areas Plan and public consultation process, which at times was marked by the complete absence of consultation and at other times, wholly inadequate consultation with regards to developments affecting its on-campus food growing system and correlate pedagogy. Using methods from Institutional Ethnography, Participatory Action Learning and Action Research, and the BIAS FREE Framework, I explore how Trent University manages its approach to land-use planning and public consultation, revealing that it is ultimately working at cross-purposes with its foundational principles. I advise that Trent University's current land-use planning model, lacking critical examination and intervention, puts the institution's academic reputation, campus ecological functions, and university-community relations at risk. If perpetuated, this model will be detrimental to the university's capacity to generate new knowledge for teaching, learning, and research, as well as context-specific solutions for its land-use planning. My findings define a new concept of fait accompli planning to describe how and why Trent's public consultation process fell significantly short of both its institutional mandate and claims of robust and comprehensive engagement. I conclude that post-secondary institutions (and beyond) need to implement dialogic approaches to planning that abandon predetermined outcomes and instead foster genuine dialogue toward a collaborative milieu of shared, informed, and deliberate planning practices.

This thesis creates an adaptation of William Shakespeare's The Tempest that reshapes the play through a focus on queer identities. Specifically, through setting the play at a Drag club and changing the characters accordingly a nuanced view of how gender roles shape the interactions we have with ourselves, our society, and our environment. The chapters that proceed the adaptation provide evidence and supporting clarification for the ideas brought up in the adaptation.

We studied the physiological and molecular responses of lab-grown Daphnia pulex to shifts in dietary (carbon, nitrogen, phosphorus, and cyanobacteria) and growth media (calcium) nutrient supply using a set of potential biomarkers via qPCR. Each examined nutrient had a strong effect on Daphnia mass-specific growth rate, and we found significant dose-dependent effects of treatment level (medium and low) on the gene expression of selected indicator genes. Furthermore, linear discriminant analysis models using different combinations of treatment levels could separate the animals between nutritional treatments with 86-100% prediction accuracy. This would suggest that Daphnia appear able to respond to nutrient limitation by adjusting their growth rate and associated molecular pathways to deal with an insufficient supply of nutrients. While this study provides valuable information regarding Daphnia's ability to adjust physiological and molecular processes under controlled laboratory conditions, more validation needs to be conducted before applying these potential biomarkers to wild populations to assess the type and intensity of nutritional stress.

Population cycles are characterized by predictable temporal oscillations in population size and are influenced by densities of both predators and prey. These oscillations are influenced by the predator functional response, i.e. the influence of prey density on predator kill rate. The Canada lynx (Lynx canadensis) is a predatory mammal with cyclic northern populations driven by snowshoe hare (Lepus americanus) density. Despite some understanding of the drivers of lynx cycles, we lack understanding of how lynx hunting behaviour, including kill site selection, is influenced by the spatio-temporal distribution of prey. These concepts are explored in chapter one of this thesis.

In chapter two, we (coauthors and I) built on work in Kluane region of the Yukon where lynx and hare populations have been tracked through several population cycles. Over six winters, we deployed GPS collars on >40 individual lynx, some of which were fitted with satellite transmitters, accelerometers, and audio recorders. We validated the use of these technologies for identifying hare kills with an accuracy of >87%. This validation is the foundation for chapter three of this dissertation.

In chapter three, we investigated the drivers of spatial variation in lynx kills. Using snow track transects through four winters of declining hare density, we developed a robust model of habitat-specific hare abundance over time. Using model predictions, in combination with lynx Utilization Distributions derived from GPS locations and related habitat associations, we determined the importance of hare abundance, lynx spatial use, and landscape characteristics such as vegetation density in determining patterns of lynx kills and space use. Lynx kill sites were most strongly predicted by lynx space use, followed by the relative abundance of hares, an index of tree cover density, and elevation. Lynx space use itself was not strongly predicted by hare relative abundance, but rather by a shift to the use of more open habitats when hares were abundant to higher use of denser habitats as hare populations declined; this apparently corresponded to temporal changes in hare distribution. This thesis helps to disentangle the drivers of spatio-temporal variation in predator foraging behaviour, with important implications for understanding predator-prey dynamics.

Transracial adoption places the child with a family of a different ethnicity than their own. In the current study we qualitatively examine concerns associated with transracial adoption and investigate the relation between parent-child relationships and child social-emotional problems. Twenty-two adopted girls from China, 20 nonadopted Caucasian girls, and 23 nonadopted Chinese-Canadian girls, between 10-14 years, and their mothers were included. Thematic content analysis of interviews with adoptive mothers revealed that the transracial adoption experience had positive, negative, and neutral aspects. This included the parent-child relationship, the adopted child's view of their physical appearance, and the incorporation of cultural elements into the home. Quantitative analyses revealed no significant differences between the three groups on measures of parent-child relationship quality and child social-emotional functioning, which confirmed findings from the qualitative analysis. In the entire sample there were significant negative relations between quality of parent-child relationship and social-emotional functioning. These results suggest that early age of adoption may help decrease the likelihood of problematic parent-child relationships and social-emotional functioning in adopted children. It would be important to re-examine this question during adolescence when racial identity forms.

In electron-doped ferroelectrics, the free electrons can become concentrated along the domain walls which act like a conducting surface. We consider the impact of free electrons occupying the t2g orbitals on the domain walls of an electron-doped perovskite ferroelectric. We build an analytical model based on Landau-Ginzburg-Devonshire theory, and a trio of tight-binding Hamiltonians for free electrons. We self-consistently solve for the polarization, potential, and electron density using a finite-difference approximation. We find that the ferroelectric is effectively charge neutral. The free electrons are attracted to the positively-charged domain wall, leaving it with a small residual charge. As the electron density increases, the domain walls tilt to form zig-zag domain walls. Orbital selectivity of the t2g orbitals depends on the relative orientations of the orbital plane and the domain wall. This property influences the rate at which the domain wall tilts as a function of the electron density.

Recovery of forest soils from chronic acidification can be enhanced with the use of non-industrial wood ash (NIWA). Non-industrial wood ash is alkaline and contains high concentrations of macronutrients, but trace metal concentrations must be evaluated to limit risk of metal toxicity following application. Additionally, understanding how different forest ecosystem components respond to NIWA is essential to inform current policy regulating its use as a soil amendment. This study evaluated the response of sugar maple (Acer saccharum) sap yield and chemistry, the response of soils beneath maple, American beech (Fagus grandifolia) and mixed species canopies, and maple and beech fine roots, foliage, seedling abundance, and understory vegetation abundance and composition to an application of 6 Mg ha-1 NIWA. Eight 40 x 40 m plots were established in a hardwood stand in Bracebridge, Ontario and were sampled prior-to and up to two years following application of NIWA (n = 4). Non-industrial wood ash significantly increased organic horizon soil pH and macronutrient (Ca, Mg, and K) concentrations with increases in Mg and K extending to the mineral soils. Significantly higher concentrations of some trace metals (Al, Fe, Mn, Cd, Cu, Pb, Zn) were also observed, but these were restricted to the organic horizons. Sugar maple sap, pH, and sweetness were unaffected by NIWA application, and while increases were observed in nutrient and metal concentrations in sap, the differences were small and variable between years, and all concentrations were consistent with those commonly found in maple sap. Fine root biomass of maple and beech trees was not affected by NIWA application, but higher concentrations of K and Mg were observed in the roots of both species, consistent with higher concentrations observed in the mineral soil horizons beneath both species' canopies. Only significant increases were observed in K in sugar maple foliage. Both critical foliar concentrations and diagnosis and recommendation integrated system (DRIS) norms for sugar maple did not indicate mineral nutrient deficiencies at this site; although this site was acidic and nutrient-poor, this may account for the lack of differences observed, particularly between species. Changes observed in understory vegetation were driven by years rather than between treatments. These results suggest that moderate doses of NIWA can provide significant decreases in soil acidity and increase nutrient availability, with limited increases in metal concentrations that are primarily restricted to the organic horizons.

The significance of nursing retention in today's healthcare system is more prominent than ever before. The purpose of this study was to answer the question: What do Registered Nurses understand about their intention to stay at Ontario rural hospitals? A qualitative descriptive phenomenological approach was used to conduct this study. Ten Registered Nurses from rural hospitals were interviewed regarding their experiences working in rural hospitals. Seven themes were developed including: Sense of Community, Pride and Identity, Weight of Responsibility, Feeling Alone, Questioning Commitment, Rural Reality, and Feeling Misunderstood. Participants shared that their nursing co-workers were the reason they continued to stay working in their rural hospitals, with the essence of the themes being we are there for each other. The findings of this study can be used to influence nursing practice, nursing education, healthcare leaders, and areas of future research.
