2017 — Reviewing and Reshaping My Teaching Towards a More Socially-Just Practice: A Self-StudyAbstract
This research text is a self-study into my development as a critical pedagogue. In it, I seek to investigate two research questions: (1) how do tensions in my teaching illustrate the systemic challenges of race and gender, which I face on a day-to-day basis, as I work towards a more socially-just teaching practice; and (2) how does the analysis of racial and gender-based teaching tensions help guide my growth toward a more socially-just professional practice? My evolving understanding of my social position in relation to systems of oppression and its effect on my teaching are central to this study. Through … Read more

2017 — Petrographic, geochemical and geochronological study of albitization associated with vein type uranium mineralization in the Beaverlodge district, northern SaskatchewanAbstract
Albitization has long been noted as having a spatial association with uranium mineralization in the Beaverlodge uranium district; however, a genetic relationship between the two has yet to be demonstrated. Previous studies mainly focused on albitization in 1.94-1.92 Ga granite, but new field and petrographic studies have shown that albitization is found to also occur in the ca. 2.33 Ga Murmac Bay Group amphibolite and the ca. 1.82 Ga Martin group sedimentary rocks. There are two types of albitization: pervasive, replacement-type (R) and vein-type (V), which are grouped into two generations: generation 1 (Ab1-R and Ab1-V) and generation 2 (Ab2-R … Read more

2013 — A Dendroclimatic Investigation of Southwestern SaskatchewanAbstract
Water resources of the southwestern Canadian Prairies are limited and sensitive to changes in climate and land cover. An increasing demand for water resources has increased vulnerability to hydrological drought. Because few instrumental records exceed 100 years, climate proxies are used to extend the historical record of natural variability. Understanding the frequency, magnitude, and duration of past climate extremes allows researchers to better forecast the probability of future extreme hydrological events. Through standard dendrochronological methods, fifteen moisture sensitive tree-ring chronologies (Pinus albicaulis, Pinus ponderosa, Pinus contorta, Picea glauca, and Pseudotsuga menziesii) were collected and updated from the Sweet Grass Hills … Read more

2020 — Assessment of the Spatial and Temporal Hydroclimatic Variability of the Canadian Prairie ProvincesAbstract
Natural climatic variability, changing climatic conditions, periodic droughts, and excessive moisture events impact agriculture, industry, municipalities, and surface water resource management throughout the Canadian Prairie Provinces. Persistent, large-area droughts are some of the most damaging natural disasters, and further understanding of both past and future climatic variability and change is imperative, as impacts to society, agriculture, and industry will likely be amplified and more severe under changing climatic conditions. Using high spatial and temporal resolution, and instrumental, regional climate model projections, and proxy (tree-ring) records, this research focussed on the frequency, intensity and magnitude of seasonal, decadal, and longer timescale … Read more

2019 — Subproduct and Product Systems of C* - AlgebrasAbstract
This thesis initiates the theory of Tsirelson C -subproduct and product systems on a solid basis of results, which extends Arveson's theory of product systems of Hilbert spaces, with emphasis on Tsirelson's two parameter version of product systems of Hilbert spaces. Within we prove that every Tsirelson C -subproduct system admits a Bhat-type dilation to a Tsirelson C -product system, analogous to the Bhat dilation of a conservative quantum dynamical semigorup to an E0-semigroup. We also construct the universal C -algebra of an arbitrary unital Tsirelson C -subproduct system that, together with its associated quantum L evy process, reflect the … Read more

2012 — Geotechnical Investigation of Uranium TailingsAbstract
With the increasing uranium demand for power generation, the mining industry is considering expansion of existing facilities. The management of tailings, generated as a by-product of ore beneficiation, in containment structures is particularly important to minimize the environmental footprint. A clear understanding of slurry behavior is required at the onset of deposition in the containment facility. The main purpose of this research was to understand the geotechnical behaviour (index properties, segregation, dewatering) of uranium tailings under field and laboratory conditions. The historical data of tailings characteristics in the Deilmann Tailings Management Facility (DTMF) at Key Lake, Saskatchewan, were analyzed to … Read more

2019 — Lithofacies Attributes, Depositional Environments, Biostratigraphy and Cyclicity of the Lockhart Limestone, Upper Indus Basin, Northern PakistanAbstract
The Indian Subcontinent contained a wide shallow marine continental shelf during most of the Paleocene and Eocene epochs before its collision with Eurasia. The Indus Basin formed the Pakistani portion of the subcontinent where carbonate deposition was prominent. The Lockhart Limestone is among the carbonate-dominated lithologic units developed in the Indus Basin. The latter has been divided into sub-basins due to the tectonic disturbance related to the Indian-Eurasian collision. In the northern part of the Indus Basin, the sub-basins Kohat, Potwar and Hazara constitute the upper Indus Basin. The study area is located in the Potwar and Hazara sub-basins. The … Read more

2024 — Analysis of dissolved organic matter character and dynamics using optical techniques in prairie wetland pondsAbstract
Carbon plays an important role in a variety of Earth’s biogeochemical processes, through its various reservoirs and the interconnections between them. The hydrosphere is an important reservoir for carbon, and inland waters have often been regarded as unimportant in carbon biogeochemical cycling. However, important transformations and transport mechanisms occur within inland waters. Wetlands are an example of this, where carbon is in flux with the atmosphere and hydrosphere. Dissolved organic carbon (DOC), the carbon fraction and majority of dissolved organic matter (DOM), is found in the earth’s aquatic environments, is an important connection in the carbon cycle between terrestrial and … Read more

2012 — Engineering Properties of Badlands in Semi-Arid RegionsAbstract
Geology and seasonal weather variations govern the engineering properties of Avonlea badlands in Saskatchewan, Canada. Three surface sediments exhibiting distinct lithologic variations were found: a steep and fissured sandstone; a mildly-sloped and popcorntextured mudrock; and a flat and eroded pediment. The variation in material composition and the water availability conditions increase the saturation-desaturation cycle that ultimately affect material behavior. The fines content increased from dry to wet state with 17% to 33% for sandstone, 4% to 98% for mudrock, and 21% to 42% for pediment. The water adsorption capacity was found to be highest for mudrock (wl = 96% and … Read more

2013 — A Fuzzy inference Systems Approach for Resource Constrained Scheduling and Closely Related ProblemsAbstract
Today, the need to use some kind of Intelligent Systems (IS) techniques from the Soft Computing / Computational Intelligence fields is rapidly growing. This is because intelligent processes have the capability to deal with problems relating user-experience-knowledge and also they can consider data being uncertain or vague. This research focuses on applying IS techniques to solve the Resource Constrained Scheduling Problem (RSCP) and some related problems. Traditional methods to solve the RSCP have proven to be useful; however, they are somewhat limited, time consuming, and not always effective. Among the traditional heuristic methods that have been used for years, the … Read more

2023 — Detection of DoS and DDoS attacks on 5G network slices using deep learning approachAbstract
A new degree of connectedness and interaction has been introduced by the development of 5G networks. By dividing a physical network into several logical networks, 5G network slicing is a special feature that gives network operators the ability to allocate specific resources and services to various applications and customers. However, 5G network slicing is susceptible to cyberattacks, particularly Denial-of-Service (DoS) or Distributed Denial-of-Service (DDoS) attacks, just like any other network. Such attacks can have a significant negative effect on network performance, degrading services and reducing the availability of slices. The primary objective of this thesis is to examine the impact … Read more

2021 — English Language Policy and Planning in Bangladesh: My Lived ExperienceAbstract
This language policy study examines the English language planning and policy of Bangladesh, a South Asian country with a long history of British colonization. Roughly 95 to 99 per cent of Bangladeshis speak বাাংলা (bangla)/Bangla as their national language but their level of literacy is routinely measured by their English knowledge. During 200 years of colonial rule, English was legislatively imposed as the language of schooling. Since gaining independence in 1971, Bangladesh continues to uphold the place of English in education. This practice produces inequitable access to education. In light of this reality, this doctoral research explores the historical and … Read more

2022 — Faciliter l’intégration des immigrants du Moyen-Orient dans la communauté fransaskoiseAbstract
This research aims to facilitate the integration of immigrants from the Middle East (with different linguistic backgrounds) into the Fransaskois community. The existing literature illustrates the importance of immigration in Canada and, particularly, in Western Canada. This immigration plays a major role in securing francophone minorities’ demographic weight. The Fransaskois community, given its flexible inclusion criteria, seems capable of integrating immigrants. Immigrants from the Middle East also show much linguistic and cultural flexibility and are willing to choose the “Francophone route” when they settle in Saskatchewan. However, in this study, through interviews with immigrants from the Middle East and representatives … Read more

2023 — Gender differences in Royal Canadian Mounted Police officers’ mental health: The role of sexual victimizationAbstract
The Royal Canadian Mounted Police (RCMP) is Canada’s national police service, comprised of over 19,000 police officers (21.7% women) who work to prevent and solve crime, uphold the law, and ensure the safety and security of Canadian citizens (RCMP, 2021). The paramilitary roots and structure of the RCMP are evident in the organizational culture (Bastarache, 2020; RCMP, 2018). Military and police cultures tend to be hegemonically masculine, suggesting the same is likely true for the RCMP (Angehrn et al., 2021; McCristall & Baggaley, 2019; Prokos & Padavic, 2002; Workman-Stark, 2015). Hegemonic masculinity is a theoretical construct that refers to the … Read more

2016 — Autonomous Visual-Inertial Navigation for Quadrotor MAVsAbstract
The aim of this thesis is to develop a system which would enable a quadrotor MAV (Micro Aerial Vehicle) to estimate its position and orientation and to autonomously navigate in unknown environments using vision as the primary source of information. To navigate in three-dimensional space, an autonomous MAV should not only possess knowledge of its current position and orientation (pose for short), but also of the world around it. While the former can be obtained using a GPS for large outdoor environments and the latter can be provided as a map, a truly autonomous navigation system should enable an MAV … Read more

2018 — Effects of Metal Coordination and Transition Metal Properties on Electrophilic Substitution Reactions of Phosphenium IonsAbstract
An investigation into the electrophilicity of metal free and metal coordinated phosphenium ions for P-C bond formation, particularly phosphine synthesis, has been carried out. Chloride abstraction from metal-free phosphines led to phosphoranylphosphonium ions, which underwent electrophilic addition reactions but were limited by adduct formation with the formed phosphines. Phosphenium ions complexes of chromium, molybdenum, iron, and platinum were investigated and compared to those of tungsten. Group VI bound chlorophosphines [Mo(CO)5(PPh2Cl)] and [Cr(CO)5(PPh2Cl)] were converted into phosphine triflates, via chloride abstraction using AgOSO2CF3, and underwent electrophilic aromatic substitution reactions with pyrrole and indole, but their applicability is limited by difficult isolation … Read more

2024 — Prevalence and predictors of alcohol use disorder among Canadian Armed Forces members and veterans with military sexual traumaAbstract
Military sexual trauma (MST) is a pervasive issue that is associated with adverse psychological and physical health sequelae (e.g., chronic health conditions, mental health disorders, suicidal ideation). Alcohol use disorder (AUD) is positively associated with MST and may exacerbate physical and mental health conditions. An elevated lifetime prevalence of MST was recently reported among Canadian Armed Forces (CAF) Members and Veterans. Still, research examining the relationship between MST and AUD within a Canadian context is lacking. Risk factors for AUD among CAF Members and Veterans with MST have also yet to be identified. The current thesis used the 2018 CAF … Read more
