2024 — Intersexual roost site selection by the little brown Myotis in Cypress Hills, SaskatchewanRésumé
Roost structures provide habitats for bats to engage in critical life processes. Identifying, characterizing, and conserving these structures is crucial for individual fitness and survival to mitigate population loss, especially for species such as the little brown Myotis facing threats such as pathogen spread from White-Nose Syndrome. During summer, little brown Myotis rely on roosts to maintain populations through successful reproduction and winter preparation, including rapid development of young and fat accumulation for the winter for all individuals. Summer daytime roosts are particularly critical for these processes to occur effectively. My research aimed to characterize the natural roost selection of … Lire la suite

2023 — Design and analysis of gesture-controlled musical instrument interfaces in extended realityRésumé
Despite the benefits of playing an instrument, many students drop out due to factors such as frustration or boredom from repetition. Virtual Reality (VR) and Extended Reality (XR) have the potential to help learners gain or maintain interest through simulating both realistic or physically impossible instruments, while experienced musicians may find new forms of inspiration or creative expression in virtual environments. Although VR can theoretically simulate any interface that can be modelled, in practice, virtual systems are limited by the user’s physical and cognitive ability to interact with the environment, and the system’s ability to replicate the feeling of an … Lire la suite

2021 — Heterogeneous Photocatalytic Degradation of N-Nitrosodiethylamine in Wash Water Unit of Carbon Capture Plants Using Tungsten Trioxide Based CatalystsRésumé
Post combustion carbon capture, a promising technology for capturing the superabundant CO2 produced by various industries has received much research and industrial attention. The use of amines for this capture process comes with its own disadvantage in that it degrades into other products some of which are harmful to the ecosystem upon its release into the environment. Chief of these degradation products are the mutagenic and carcinogenic nitrosamines which have received much research attention in both carbon capture processes and wastewater treatment plant processes. Several treatment methods such as biological methods, activated carbon, UV in conjunction with ozone or reverse … Lire la suite

2023 — Psychopathology and comorbidity in public safety personnel: A network analysisRésumé
The categorical approach to mental health diagnosis employed in the Diagnostic and Statistical Manual of Mental Disorders – Fifth Edition (DSM-5) proposes that many symptoms of psychopathology possess the same diagnostic weight and symptoms that are highly correlated form clusters. Two competing views for why symptoms cluster together dominated the psychological and psychiatric literature of the 20th century. The most prevalent psychological theory posits that symptoms cluster together due to unobservable latent variables—latent variable theory. The most espoused psychiatric theory proposes that the signs and symptoms of a disorder cluster due to a shared underlying brain disease pathology. The vast … Lire la suite

2011 — Natural Gas Development and Grassland Songbird Abundance in Southwestern Saskatchewan: The Impact of Gas Wells and Cumulative DisturbanceRésumé
The quantity and quality of remaining grasslands in southwestern Saskatchewan, Canada, are threatened by expansion of natural gas development. The number of natural gas wells nearly tripled between 1997 and 2007. Current management strategies do not consider the effect of natural gas development on grassland birds because the impacts are not known. I examined grassland songbirds and vegetation structure across an area with a gradient of gas-well densities to determine whether (1) density and proximity of gas wells influence abundance and occurrence of grassland songbirds or (2) the relative and cumulative effect of different types of anthropogenic disturbances associated with … Lire la suite

2011 — Effects of Anthropogenic Urea on Lakes of the North American Great Plains: Ecological Implications Based on Experimental and Observational StudiesRésumé
Urea consumption has increased dramatically since the 1960s and now comprises over 50% of the nitrogen (N)-based fertilizer used globally. Currently, only 30-50% of N-fertilizers applied to cropland are effectively used by crops, while the remainder is lost to the environment. Urea is also a component of livestock and human wastes. In principal,export of urea to lakes as a consequence of human activities may exacerbate ecological problems associated with eutrophication (e.g. increased productivity of aquatic fauna, deep water anoxia, biodiversity loss, fish kills, etc.), especially in phosphorus (P)-rich aquatic ecosystems. Biweekly measurements of urea content and limnological variables (water chemistry, … Lire la suite

2017 — Tall Timber: Roost Tree Selection of Reproductive Female Silver-Haired Bats (LASIONYCTERIS NOCTIVAGANS)Résumé
Habitat loss is the most significant contributor to the extinction of species worldwide, and yet for many species, habitat requirements remain largely unknown. Identifying habitat is important, especially because the most cost effective strategy for conservation and management is preserving habitat before it is converted or degraded rather than trying to restore it after the fact. Identifying habitat is also important from a scientific perspective because it can help to explain some of the ecological choices made by individuals when potentially conflicting priorities exist. Habitat requirements change for many species, both seasonally and throughout their life cycles, and identifying habitat … Lire la suite

2016 — Playing the (Policy) Fields: The Lesbian and Gay Movement and the Development of the Modernization of Benefits and Obligations BillRésumé
The lesbian and gay rights movement in Canada has a rich history comprised of numerous groups and individuals that worked tirelessly for decades to promote lesbian and gay rights and champion for protections to the community at a number of levels. One of the primary challenges that occurred was in relation to relationship recognition. Throughout the 1970s, 80s, and 90s in Canada, the lesbian and gay movement worked to achieve relationship recognition, challenging the criminal code, human rights protections, and finally full relationship recognition through the Modernization of Benefits and Obligations Act in 2000. Using the theory of fields as … Lire la suite

2021 — Heterogeneous Photocatalytic Treatment of Wastewater from Amine-based Carbon Capture PlantsRésumé
Amine-based Carbon Capture (ABCC) is the advanced, cost-effective technology used to control climate change by capturing CO! emissions. Although it has been demonstrated commercially, amine degradation poses a significant threat to humans and aquatic life. Amine degradation produces a wide variety of complex products. Some of them are carcinogenic and mutagenic such as nitrosamines and some organic acids that have demonstrated acute toxicity for laboratory animals. In order to mitigate the adverse impact of these compounds on human health and aquatic life, heterogenous photocatalysis, an advanced oxidation process, which can degrade a wide variety of chemical species with the potent … Lire la suite

2011 — Universal Mutual Responsibility: Heidegger, Selfhood, and the Possibility of an Ethics of CommunityRésumé
Martin Heidegger's treatise Being and Time, in seeking to answer the question of the meaning of Being, addresses the subject of the self and various problems relating to selfhood as component parts of his larger project. While addressing the subject of the self, however, Heidegger has overlooked many important considerations, specifically with regards to the way the self interacts with and depends upon its others. The end result of this is that Heidegger's understanding of the self throughout Being and Time carries with it both demonstrable inconsistencies and a number of propositions that require further investigation. This study, thus, has … Lire la suite

2019 — Maintaining the undercurrent from within: White settler teacher identities in Saskatchewan schoolsRésumé
Drawing upon critical perspectives, this qualitative multiple-case study examines the self-perceived identities, perceptions and pedagogical practices of four experienced (5+ years of service), white settler teachers currently teaching in an urban school division located in the province of Saskatchewan, Canada. This study explores two research questions: How do the identities of white settler teachers shape their perceptions of race and language? How do these perceptions construct their pedagogical practices? Through analysis of interview data, this study illustrates the ways in which white settler teachers reproduce discourses of whiteness to maintain colonial racial and linguistic hierarchies in settler schools today. Findings … Lire la suite

2023 — Institutional betrayal and trauma in child welfare workers in Western CanadaRésumé
Child welfare workers report a high prevalence of mental health concerns, such as posttraumatic stress and depressive symptoms, after directly or indirectly experiencing workplace traumatic events (Regehr et al., 2000, 2004). Factors within an organization, such as supportive administrators, supervisors, and coworkers (Boyas et al., 2012; Dagan et al., 2016) can impact reported mental health symptoms. Institutional betrayal research, as an extension of betrayal trauma theory, suggests that institutions play a role in impacting the development and severity of mental health symptoms in individuals who are dependent on them. Institutional betrayal, the actions or inactions of an institution when responding … Lire la suite

2012 — Randomized Controlled Feasibility Trial of a Self-Help Book for Health AnxietyRésumé
The purpose of this feasibility study was to determine the efficacy of a cognitive-behaviour therapy (CBT) self-help book for health anxiety titled, It’s Not All in Your Head (Asmundson & Taylor, 2005) relative to a wait-list control. It was hypothesized that using a CBT self-help book would be a more efficacious treatment than wait-list control. Health anxiety is marked by anxious preoccupation about having a physical disease, based on the catastrophic misinterpretation of innocuous bodily sensations. It is associated with unpleasant physiological, behavioural, cognitive, and affective symptoms. When elevated, health anxiety affects an individual‘s interpersonal relationships, especially with his or … Lire la suite
