2016 — Development of an Integrated Hydro-Climatic Systems Analysis Framework and its Application to the Athabasca River Basin, CanadaRésumé
Climate change has profound impacts on regional hydrological characteristics in large unregulated continental river basins (LUCRiBs) such as the Athabaasca River Basin (ARB), Canada. A systematic analysis of these impacts is confronted with many challenges. For instance, the performances of general circulation models (GCMs) vary with many factors, e.g. climate variables, geographic locations, temporal scales, and evaluation measures. Mesoscale atmospheric features can barely be provided by coarse-resolution GCMs. Filling this gap by statistical downscaling is further challenged by redundant computations, resulting from spatial climatic similarities, and the complexities of data uncertainties, nonlinear correspondences, normality prerequisites, and multivariate dependencies. Climatic projection … Lire la suite

2016 — Construction of Asymptotic Confidence Ellipse for Pathogen Parameters of Beta-Poisson Dose-Response ModelRésumé
Beta-Poisson dose-response model is a popular parametric dose response model which is extensively applied in Microbial risk area. The advantage of Beta-Poisson dose-response model is that it is a model which can consider the change in the risk. The change is possibly happened because of human responses diversity, pathogen competence diversity, or the interaction between them. In our project, we divide it by two parts. The rst part is the Theoretical Part. We will nd we cannot use the Method of Moments and Maximum Likelihood Estimation directly to create the Con dence Ellipse for simultaneous estimation of Beta-Poisson dose-response model … Lire la suite

2018 — Pierre Trudeau's Just Society: Bold Aspirations Meet Realities of GoverningRésumé
This thesis considers Pierre Trudeau’s first term as prime minister from 1968 to 1972 to determine his success in delivering on his key promise of a Just Society made during the 1968 electoral campaign. Trudeau had promised that his government would remove all social and economic barriers to allow the full participation of all citizens to enjoy all of the democratic, social, and economic benefits Canada had to offer. It investigates why, in the span of less than four years, the central message embodied in Trudeau’s 1968 electoral platform largely disappeared from his government’s agenda. This thesis contends that the … Lire la suite

2023 — "Who did I get to be?" Racialized and gendered discourses and the shaping of Indigenous girls' subjectivities in a northern Saskatchewan high schoolRésumé
This study explores how school discourses of race and gender have shaped the subjectivities of Indigenous girls in a provincial high school in Northern Saskatchewan. Feminist poststructural theory, race critical theories, and spatial theory have been used as theoretical frames to examine how Indigenous female students have taken up racialized and gendered discourses from their high school experiences. This study also examines the relationship between discourses of race and gender and the formation of identity constellations, theorizing that socially constructed identity categories do not operate separately in the constitution of student subjectivities. Specifically, this study focuses on former students of … Lire la suite

2014 — The Development of Context-Specific Biofeedback Training Screens – An Application to Hockey OfficialsRésumé
The benefits and potential of biofeedback training for enhancing athletic performance has received noticeable consideration in both research and practice. While most biofeedback research applied to sport participants has focused primarily on athletes, one group of participants has been neglected in both research and training. This group is known as sports officials. Ice hockey officials are required to possess various physical, cognitive, and psychological skills, suggesting that biofeedback training to enhance their on-ice performance holds strong utility. Since biofeedback research applied to sport offers very little perspective into the needs and requirements of biofeedback protocols applied to officials of sport, … Lire la suite

2018 — Quantile Regression Approach For Analyzing Gene Expression DataRésumé
Temporal gene expression data contains ample information to characterize gene function and is now widely used in bio-medical research. A dense temporal gene ex- pression usually shows various patterns in expression levels under dfferent biological conditions. Existing literature models the gene trajectory using the mean function. Also, temporal gene expression curves generally show a strong degree of heterogeneity between multiple conditions. As a result, rate of change of gene expression may be dfferent in non-central locations and a mean model can not capture the non-central location of the gene expression distribution. However, the mean regression model depends on the normality … Lire la suite

2024 — A novel beam management strategy using UE trajectory mappingRésumé
This research presents a novel beam management strategy aimed at optimizing performance in multi-user mobile communication systems, specifically within the framework of 5G mmWave networks. As the demand for reliable and high-speed data transmission increases, traditional beamforming techniques face challenges such as high computational load and inefficiencies in indoor environments. The proposed method leverages user equipment (UE) trajectory information by segmenting user trajectories into equal-length segments, focusing the beam on the centre of each segment to ensure stable and consistent signal coverage. The methodology integrates angular weighting, and dynamic power control to enhance beamforming efficiency. The angular weighting function prioritizes … Lire la suite

2016 — Geochemical and paleo-geothermal Studies of the basinal fluids in the Athabasca Basin - Implications for unconformity-related uranium mineralizationRésumé
The Athabasca Basin and its crystalline basement host the largest high-grade unconformity-related uranium deposits in the world. It is generally agreed that the mineralizing fluids were basinal brines of evaporitic seawater origin, which became enriched in U and Ca through fluid-rock interactions. However, it remains controversial whether these metals were extracted from the basin or the basement, and what driving forces were responsible for fluid flows. A good understanding of the composition and temperature of the basinal fluids before they entered the sites of mineralization is important in order to address these problems. Detrailed petrographic, geochemical, fluid-inclusion, and illite geothermometric … Lire la suite

2020 — Aspect Social et Dimension Du Pidgin-English et Camfranglais Face Aux Langues Officielles Du CamerounRésumé
Home to several languages, Cameroon has a complex linguistic situation that resulted in the creation of other languages (Cameroon pidgin and camfranglais) to facilitate easy communication. Cameroonian Pidgin is considered to be a flexible, fast growing and unifying language, undergoing a rapid transformation in a constantly changing society. It is a language which grows in the eyes of Cameroonians, spoken by the rich and poor, educated and uneducated, young and old, and it transcends geographical and political boundaries because it is not a language of a particular ethnic group. Cameroonian pidgin is considered the lingua franca in everyday life in … Lire la suite

2021 — Space Use by Piscivorous Birds, Fish, and Humans on a Multi-Use Lake in Southern SaskatchewanRésumé
On the Great Plains of North America, freshwater lakes are a critical resource in a dry landscape. Recreational development and use of lakes, as well as industrial and agricultural uses, may alter habitat and water quality. Consequently, it is important to understand how economically important fish species (walleye Sander vitreus; northern pike Esox Lucius; and burbot Lota lota) use lakes and identify key areas for protection and management efforts. Conflicts between humans and fish-eating birds over fisheries resources have also emerged and may be exacerbated by the limited availability of freshwater. In this context, the double-crested cormorant (Phalacrocorax auritus) and … Lire la suite

2015 — The Role of The Saskatchewan Herald in the Construction and Extent of the “Siege of BattlefordRésumé
This thesis examines the role played by The Saskatchewan Herald in the construction of the circumstances that led to the 1885 Siege of Battleford. Generally discussed only as a peripheral event of the North-West Rebellion, the Siege of Battleford involved approximately five hundred men, women and children who congregated within the walls of a small North-West Mounted Police fort. Terrified of the intentions of their First Nations neighbours, the ‘siege’ lasted for more than a month and ended only with the arrival of Colonel William Dillon Otter’s column of the North-West Field Force. The self-protective action taken by the citizens … Lire la suite

2021 — Acute Psychological Stress and Food Intake in Humans: A Scoping ReviewRésumé
In response to stress, stress-sensitive systems, including the sympathetic-adrenal-medullary (SAM) axis and the hypothalamic-pituitary-adrenal (HPA) axis, are activated to enable the individual to engage in the fight-or-flight response resulting in catecholamine (e.g., epinephrine and norepinephrine) and cortisol release. Stress-induced cortisol secretion has been shown to elicit a decrease, increase, or no change in the homeostatic mechanisms of food intake (e.g., appetite, appetite hormones, food intake). However, homeostatic control can be overridden by hedonic (or pleasure-inducing) mechanisms. Stress can increase cravings of unhealthy palatable food causing alterations in food preference (e.g., sweet foods), enhancing the motivation for their acquisition (i.e., food … Lire la suite

2014 — Using Occupancy Models to Predict Grassland Bird Distributions in Southeastern AlbertaRésumé
Widespread population declines of grassland birds have stimulated a variety of conservation plans, many of which promote a landscape approach to conservation. Identifying needs for survival and reproduction, and prioritizing key habitat requirements that influence where species occur on the landscape is an essential first step to guiding long term management efforts. I used single-species, single-season occupancy models to (1) identify landscape factors influencing the distribution of grassland bird species, (2) generate predictions of species distributions in southeastern Alberta, and (3) evaluate the predictive performance of each species model with two sources of evaluation data. In 2012, I conducted three … Lire la suite

2015 — The Effect of Knee Osteoarthritis on the Variability and Fractal Dynamics of Human GaitRésumé
Knee osteoarthritis (OA) is the most common joint disease seen in the older adult population, and has a greater influence on gait compared to the effects of aging alone. Spatiotemporal parameters can be used to quantify age-related changes in gait, however gait variability (i.e., the magnitude of stride-to-stride fluctuations with respect to time) and the fractal-scaling index (FSI) (i.e., correlated self-similar patterns of gait) can provide better information about the rhythmicity of the gait cycle over time. Recent studies have shown a relationship between knee OA and gait variability for certain spatiotemporal parameters, but the evidence is still preliminary and … Lire la suite

2020 — U-Pb Geochronology, Geochemistry, and Isotopic Composition of Archean and Paleoproterozoic Granitoids of NW Saskatchewan: Implications for Arrowsmith Orogenesis and the Origin of the Nolan-Zemlak Domain BoundaryRésumé
This regional-scale geochemical-isotopic study aims to constrain the igneous petrogenesis of west-southwest Rae granitoids to test if the Nolan-Zemlak domain boundary is an Arrowsmith-aged (2.5-2.3 Ga) suture zone. The oldest (3.0 Ga) granitoids in the region, located in the Beaverlodge domain, have a ‘subduction-like’ signature along with high Na2O concentrations, Sr/Y and La/Yb ratios and low Y and Yb concentrations indicative of a TTG (Tonalite-Trondhjemite-Granodiorite) suite. The 2.6 Ga Nolan granitoids have similar geochemical signature suggestive of an ‘subductionlike’ tectonic environment for emplacement. However, they lack the high Na2O concentrations typical of a TTG suite. The ca. 2.52 Ga Zemlak … Lire la suite

2013 — Lessons of the Ancients: Thinking About War in Early Modern EnglandRésumé
Early modern English warfare has been harshly treated in twentieth-century historiography: while historians put out sweeping works touting, and debating, the grand military achievements of early modern Europe, England found itself berated for its apparent backwardness and inefficiency. However, recent trends not only in reconsidering the effectiveness and needs of early modern English warfare, but also in debating the extent of the Greco-Roman influence over early modern culture in general, warrant a re-examination of early modern English warfare altogether. Given the large number of works available at the end of the sixteenth and beginning of the seventeenth centuries on warfare … Lire la suite
