2017 — The Efficacy of Aerobic Exercise and Resistance Training for Anxiety-Related Disorders and Constructs: A Randomized Controlled TrialAbstract
Anxiety-related disorders are highly prevalent and comorbid, affecting nearly one third of individuals over their lifetime. Evidence suggests that anxiety-related disorders share common etiology, latent structure, higher-order dimensions, and response to treatment. These similarities have fostered the development of transdiagnostic treatments that can effectively target a relatively wide array of anxiety-related psychopathological concerns and can also be widely and efficiently disseminated to individuals in need treatment. There is empirical evidence to support the use of physical activity, primarily aerobic exercise, as an effective intervention to treat a variety of mental health concerns; however, what effect exercise has on anxiety-related disorders … Read more

2014 — Can a Single Bout of Aerobic Exercise Reduce Anxiety Sensitivity? A Randomized Controlled TrialAbstract
A growing body of research supports the benefits of exercise for a variety of mental disorders, including anxiety. Several mechanisms have been posited for the anxiolytic effects of exercise, including reductions in anxiety sensitivity (i.e., fear of arousalrelated sensations, based on the beliefs that these sensations may have harmful or negative consequences) through exposure to these feared bodily sensations. Studies on aerobic exercise lend support to this hypothesis; however, research comparing exercise to placebo controls and evidence for the dose-response relationship between exercise and reductions in anxiety sensitivity are lacking. The present trial was designed to investigate reductions in anxiety … Read more

2012 — Agent-Based Household Energy Consumption Model for the City of ReginaAbstract
The Regina household energy consumption model is designed to estimate residential energy consumption for the city of Regina using agent-based technology. The impact of social and economic factors on the levels of energy consumption has been taken into account. It is built on Complexity & Organized Behaviour Within Environmental Bounds (COBWEB) technology, which is a platform design for multi-agent simulation. COBWEB was developed to study agent adaptation to environmental variability and change. The Regina household energy consumption model uses COBWEB’s agent technology to represent the households and people within the households of the city of Regina in 2003. Each household … Read more

2016 — Value Pluralism: What It Is and Why Its Main Arguments FailAbstract
Value pluralism is the philosophic position that there is a multiplicity of distinct goods that can neither be reduced to a common property nor be arranged into an ethical system that gives unconditional moral principles. Value monism is the position that there are common features belonging to all those things that are good which make them good, or at least that those goods can be arranged into a single, absolute moral system. According to pluralism there are a variety of competing moral systems, but no single system is authoritative. While pluralism is often dismissed as relativistic, this thesis argues that … Read more

2016 — An Examination of the Mineralogy and Lithology of the Bakken Shale with Implications upon the Bakken Petroleum System, Southeastern SaskatchewanAbstract
Late Devonian and Early Mississippian Bakken shales are important source rocks to the oil accumulations in southeastern Saskatchewan. However, to date there is lack of knowledge concerning the mineralogy and lithology of the Bakken shales, which may impact the source effectiveness and heterogeneity of the Upper and Lower Bakken shales. This research investigates the mineralogy and lithology of the Bakken shales in southeastern Saskatchewan based on results from detailed core and rock thin-section examination, scanning electron microscope-back-scattered electron imagery and energy-dispersive spectrometry analysis (SEM-BSEI/EDS), and X-ray diffraction analysis (XRD) of sixty-eight selected samples from seven wells. Based on the mineralogy … Read more

2017 — Evaluation of City of Regina Stormwater Retention and Treatment Pond PerformanceAbstract
Municipal storm water retention ponds are required to protect property, reduce negative water quality characteristics and impacts of first flush materials on receiving waters, and mitigate against peak flow challenges for treatment systems and receiving waters under high precipitation or spring flow conditions. To that end, research was completed to review the current operating performance and identify potential concerns with water quality outflows from several of the City of Regina municipal ponds. Additionally, optimization and maintenance suggestions are made to improve performance, where appropriate. The research focuses on retention ponds that are designed to serve as constructed wetlands, as these … Read more

2015 — Sites of Living Pedagogy in (French) Teacher Education: An Autoethnographic Self-StudyAbstract
The aim of this dissertation is to illuminate the sites of my living pedagogy as a teacher educator who works in a minority language context. Using a fragmented narrative approach and calling upon poststructural and feminist theory, this autoethnographic self-study privileges two guiding concepts. The first originates from the work of Bullough and Pinnegar (2001) who explain that, “the aim of self-study research is to provoke, challenge, and illuminate rather than confirm and settle” (p. 20). The second guiding concept is Aoki’s (2005) notion of living pedagogy. Aoki states that “for a teacher researcher, an insistent question is, “Where is … Read more

2023 — Design and validation of a data-driven infrastructure decision and planning framework for improving climate resiliency of small municipalities and rural communitiesAbstract
The Intergovernmental Panel for Climate Change calls for local governments to be the drivers toward resilient communities concerning climate change. Resilient municipalities must make decisions incorporating climate change to reinvest in an aging infrastructure network. The challenge is that small municipalities need access to information or the capacity to make informed decisions. Expenses related to specialized engineering for asset management and prioritization are a high cost for the municipality, where the municipality may see the value in prioritizing the funds toward operations and maintenance practices. In response to this challenge, a framework is created and presented to summarize this concept … Read more

2024 — Exploring the Twitch.tv phenomenon: Secondary students' lived digital citizenship experiences on Twitch.tvAbstract
This study explored the lived experiences of secondary students in Saskatchewan on the popular live-streaming platform Twitch.tv (hereafter, Twitch) in order to understand their perceptions of digital citizenship in such interactive online spaces. Hermeneutic phenomenology was used to analyze interviews with eight participants who spoke about their experiences on Twitch. Analysis of the interview data generated two major themes. The first major theme, digital engagement, was bisected into two subthemes: using without the manual and safety in anonymity. The second major theme, digital awareness, was also parted into two subthemes: (digital) citizenship and digital literacy. The interview data showed that … Read more

2023 — Evaluation of anxiety treatment for children through online education (ACE)Abstract
Child anxiety is very common and can potentially have lasting, harmful effects. Cognitive behavioural therapy (CBT) is an effective treatment for child anxiety, but access to traditionally delivered (i.e., face-to-face) CBT is limited. Low-intensity interventions are more accessible to families and less time-consuming for therapists, allowing for therapists to help more families. Anxiety Treatment for Children Through Online Education (ACE) is a low-intensity, therapist-guided, parent-directed, Internetdelivered cognitive behavioural therapy (ICBT) intervention for child anxiety. The implementation of ACE has yet to be comprehensively evaluated. This intervention is relatively unique within the field. Past research on ACE has aimed to investigate … Read more

2022 — Genomic and experimental insights into the ecology and evolution of transferable genetic elementsAbstract
Bacteria have dynamic genomes that allow them to adapt and survive almost anywhere on Earth. This genetic flexibility is facilitated by mobile DNA elements, which can transfer within or between genomes independently of cell lineages and drive bacterial evolution. Mobile genetic elements influence many aspects of bacterial life by encoding and transferring antimicrobial resistance genes, pathogenicity factors, and toxin-antitoxin modules. Plasmids, integrons, and genomic islands are several types of mobile DNA elements that can carry beneficial genes which help host cells adapt to new environments or provide new ecological functions. However, much is still unknown about how mobile genetic elements … Read more

2018 — A Narrative Inquiry into Experiences of Urban Indigenous Youth Within An Intergenerational After-School Wellness ProgramAbstract
In the fall of 2013, my colleagues, Sean Lessard, Lee Schaefer, and I were awarded funding through Indigenous and Northern Affairs Canada to implement an after-school program for urban Indigenous youth within an urban centre within Saskatchewan, Canada. Our intent from the outset was to create a connecting space that would allow us, as narrative inquirers, to ethically enter into the community and to develop relationships with youth and their families. The after-school program occurred each Wednesday during the school year, within an elementary school gymnasium. With an interest in physical activity, I looked to engage youth in numerous movement … Read more

2013 — Mental Health Services in Canada: Building a Model of Mental Health Care UtilizationAbstract
Existing research literature shows that mental health care services are under-utilized among individuals who have mental health problems. In Canada, it is estimated that only 40% of individuals who have mental health problems are provided with mental health care. Although some past research have examined predictors of mental health care utilization, there are gaps in our knowledge of how these predictors interact with one another and how these predictors specifically affect mental health care utilization in Canada. In this study, data from the 2007/2008 Canadian Community Health Survey (CCHS) were used with the goal of developing a more accurate picture … Read more

2013 — Your Children – Our Students: Can Saskatchewan Parents and Schools Connect in Support of Career Development of Youth?Abstract
Research has identified that parents are a key influence in the career planning process of adolescents. Despite this, limited research exists in regard to how schools and parents/guardians might connect in support of the career development process of youth. The purpose of this research was to explore what Saskatchewan parents/guardians do to support the career development process of their high school aged children, investigate what types of school-based supports parent/guardians deem most helpful in support of their children, and attempt to identify if and how parents/guardians and schools might connect in meaningful ways in support of the students’ career exploration … Read more

2018 — Exploring GTRS Based Recommender Systems With Users of Different Rating PatternsAbstract
Recommender systems predict a new user's opinion on a collection of items by analyzing preference information of similar users. The Pawlak rough set model is one of the e ective tools to make personalized recommendations. The game-theoretic rough set (GTRS) model improves the quality of the Pawlak rough set based recom- mendations by determining a pair of thresholds that could achieve a tradeoff between accuracy and coverage, which are two of the most prominent recommendation evalua- tion metrics. It should be noted that the performance of a recommendation algorithm may be affected by the rating patterns of the users in … Read more
