2015 — From Damsel in Distress to Predatory Harlot: Historiography and the Fourtheenth-Century Queen Isabella, "She-Wolf of France"Résumé
Abstract Interpretations of Queen Isabella of France, known as both “the fair” and “the she-wolf of France,” have changed drastically since her life in the fourteenth century. Originally she was presented as a model queen and an exceptional wife. She supported her husband, Edward II of England, and excelled in diplomacy. Interpretations following her fall from power have, however, often presented her as inept and grasping. This dichotomy created two distinct Isabellas: the charming damsel of contemporary sources and the greedy harlot of her later biographers. Combining these two halves into a composite has proved challenging for historians of Isabella. … Lire la suite

2015 — The Geography of Crime: Examining the Distribution of Break and Enters Across Regina Neighbourhoods Using Geographic Information Systems (GIS)Résumé
Crime is not a random event that occurs evenly across time and space; instead, it is clustered in certain areas known as hot spots (Sherman, Gartin, & Buerger, 1989). Understanding patterns of crime and the reasons why hot spots exist provides a foundation for crime control and prevention strategies. This study provides an analysis of the distribution of break and enters in Regina, Saskatchewan using calls for service, both emergency and non-emergency, made to the Regina Police Service (RPS) in 2006. The researcher coded and analyzed the data using ArcMap, a Geographic Information System (GIS). Pairing calls for service data … Lire la suite

2020 — Characterization of Herbaspirillum huttiense L4.2, evaluation of plant growth promotion when associated with Oryza sativa and exploration of radiolabelling techniques to study plant−microbe interactionsRésumé
Studying plant−microbe interactions is essential to understanding the mechanisms of plant growth promotion by bacteria. The aim of this work was to explore the relationship between Herbaspirillum huttiense L4.2 (HH L4.2) and rice. This was accomplished by: i) characterizing HH L4.2; ii) analyzing confocal images of green fluorescent protein (GFP)-labelled cells to understand colonization and endophytic behaviors; and iii) using positron emission tomography (PET) imaging that allowed for visualization and quantification of radioactive tracers to understand nutrient distribution and exchanges between HH L4.2 and rice. A promoterless GFP gene was randomly integrated in the genome of HH L4.2 via transposition … Lire la suite

2023 — Sword fighting in virtual reality: Where are we and how do we make it realRésumé
Virtual Reality has historically been a research space concerned with recreating the natural world around us. It is currently best known for its role in gaming and escapism. A number of different mediums have used virtual reality for its strengths in training. It is particularly useful for its ability to recreate real world locations and situations while still having full control over the environment. One area where it has failed in this realism is in its portrayal of fencing. Fencing, also known as sword fighting, is a common interaction in virtual reality gaming. Virtual reality fencing is plagued by a … Lire la suite

2025 — Neurophysiological mechanisms of dual-tasking in people with multiple sclerosisRésumé
Saskatchewan has one of the highest rates of multiple sclerosis (MS) globally, affecting approximately 4,000 people within the province. An emerging topic of study within MS rehabilitation is dual-tasking (i.e., the performance of two tasks simultaneously). Reports on dual-task performance among people with MS (PwMS) vary in the literature, with past research limited by methodological differences and minimal consideration of the underlying neurophysiology. Studies suggest that changes in inhibitory neural activity in the motor cortex may support dual-task performance in healthy adults, as assessed by transcranial magnetic stimulation (TMS) techniques. Other TMS work indicates that MS alters corticospinal inhibition, but … Lire la suite

2016 — Gender, Race, and Custodial SpaceRésumé
Indigenous* people have higher levels of representation in correctional facilities compared to their representation in the Canadian adult population. This trend is consistent within the female inmate population. In 2008/2009 the highest proportion of female admissions in Canada was found in Saskatchewan where Indigenous women comprised more than 85% of admissions (Calverley, 2010) despite comprising just 14.9% of Saskatchewan’s total population (Indigenous Population Profile, 2006). This over-representation presents a challenging dilemma. The racial identity assigned to Saskatchewan custodial facilities is Indigenous, which reinforces the long-standing societal belief Indigenous people are characterized by degeneracy and supports the continued exclusion of Indigenous … Lire la suite

2022 — Customer satisfaction as a critical success factor for ERP designRésumé
Enterprise Resource Planning (ERP) has been an important tool over the last number of years in managing business processes for large corporations. An ERP is a software system that links various departments and allows them to work together through a centralized software system. An example would be a hotel management ERP where multiple departments such as accounting, front desk, housekeeping and human resources share vital business information. However, more research needs to be done on ERP initiatives for small to midsized enterprises (SME) to also help them reach their productivity goals effectively. This is, in part, the motivation behind this … Lire la suite

2022 — Motivators of recreational Cannabis consumption in CanadaRésumé
Using Canada’s National Cannabis Survey, we analyze the behaviour of self-reported consumers and non-consumers of both legal and illicit recreational cannabis, post-legalization. Using a two-part hurdle model, we find that: males are more likely to consume legal cannabis than not consume at all, but are not more likely to consume illicit cannabis than none at all; and that teens are more likely to consume illicit cannabis and less likely to consume legal cannabis. Once consuming, males consume the same amount of illicit cannabis as non-males, but more legal cannabis than non-males. Being retired or being unemployed have no effect on … Lire la suite

2021 — Picturing Wonderland: Filming Fantasy in Adaptations of Carroll's Alice StoriesRésumé
The purpose of this thesis is to provide a corrective to recent approaches to fantasy in adaptation studies that focus on sayable ideas to the detriment of the experience of fantasy as such. A key figure in the definition and exploration of different modes of fantasy is Tzvetan Todorov, and it is via Todorov’s work that I attempt to rethink the study of fantasy in the context not of literature but of cinematic adaptations of literature. Specifically, I use cinematic adaptations of Lewis Carroll’s foundational fantasy novels Alice’s Adventures in Wonderland and Through the Looking-Glass, and What Alice Found There … Lire la suite

2019 — Applications of Synchrotron Radiation Techniques To The Study Of Taphonomic Alterations and Preservation in FossilsRésumé
Fossils have traditionally been seen as sedimentary rocks that preserve little of the original composition of animals, except for their shapes, and perhaps some original material from recalcitant mineralized structures, such as bones, and teeth. However, recent studies have shown that not the case. Researchers have identified preserved organic molecules, such as collagen and melanosomes, as well as mineralized soft tissues, including feathers, muscle tissue and skin, tens of millions of years after the animal's death. These results have improved our understanding of extinct species, and have been obtained using a variety of characterization techniques, including the synchrotron-based approaches that … Lire la suite

2014 — Particle Identification with the ND280 Fine Grained Detectors for the T2K ExperimentRésumé
The main goal of this thesis is the development of an algorithm for identification of particles (protons, electrons, muons and pions) with trajectories contained within the Fine Grained Detectors of the T2K (Tokai-to-Kamioka) experiment. This is achieved by constructing a distribution that compares the distance and the energy deposited by a particle travelling in the detectors. Using this distribution, a probability density function is created using simulations for particles interacting in the FGDs. The method of comparison includes the calculation of the pull variable, which gives a measurement of how close a particle being analysed is to a determined particle … Lire la suite

2012 — Cyclization modes in type III polyketide synthases and the synthetic compounds used as probes for mechanistic studies.Résumé
Type III polyketide synthases (PKS) catalyze different cyclization reactions of linear polyketide intermediates to produce polyketides with distinct ring structures. The mechanisms of pyrone and resorcinol ring formation in type III PKSs remain unknown, despite many years of research on this family of enzymes. Compounds, thought to be intermediates in these enzyme reactions, have been synthesized and used to probe the enzyme mechanisms. To study the mechanism of resorcinol ring formation catalyzed by STS and ArsB, triketo acids and 9-phenyl-3,5,7-trioxo-8-nonenoic and 3,5,7-trioxoeicosanoic (16a and 16b) and their structural analogs were synthesized. STS failed to produce any cyclized products from the … Lire la suite

2015 — Defending Canada: Canadian Military Preparedness, 1867- 1902Résumé
There has been an impression created by scholars that Canadian politico-military actions were taken to benefit Great Britain and fulfill the needs of the Empire. This thesis contends that decisions surrounding military preparedness, defense spending and the militia made by the Canadian government were designed primarily to protect and foster Canadian state interests that slowly evolved over the three decades before the Boer War in 1899: in the first phase, continued military solidarity with the British was demonstrated, especially during the Red River Rebellion (1869-1870); in the second phase, new threats and armed deployments showed an obstinate desire for autonomy … Lire la suite

2018 — Sustainable Closed-Loop Supply Chaing Network DesignRésumé
Sustainable Closed Loop Supply Chain (CLSC) management is increasingly adopted by companies, due to increasing concerns for the environmental, legislative compliance, decreasing availability of raw materials, and customer demands for environmentally friendly products. Sustainable CLSC network design provides a platform which ensures an effective and efficient supply chain management. In this thesis, the sustainable CLSC network design problem was formulated deterministically via Mixed Integer Linear Programming (MILP), and nondeterministically via Fuzzy Multi-objective Mixed Integer Linear Programming (FMOMILP) model, by considering sustainability and uncertainty. Fuzzy programming approaches were utilized to solve the problem. Two multi-objective evolutionary algorithms were employed to find … Lire la suite

2015 — Development of On-Line Analytical Technique for Determination of Composition of CO2-Loaded Formulated Amine Solvents Based on the Liquid Thermo physical Properties for a Post-Combustion CO2 Capture ProcessRésumé
One of the ways to boost the carbon dioxide (CO2) capture performance of amine based solvents is to blend a primary or secondary amine with a tertiary amine. This has been shown to be true in the blending of monoethanolamine (MEA) with either methyldiethanolamine (MDEA) or diethylaminobutanol (DEAB), resulting in quaternary amine systems of MEA-MDEA-H2O-CO2 and MEA-DEAB-H2O-CO2, respectively. However, one of the challenges is ensuring that the blending ratio remains constant throughout the entire duration of the CO2 capture operation considering the relative volatilities of the components of the blended amine solvent. In this work, two quaternary amine systems: MEA-DEAB-H2O-CO2 … Lire la suite

2022 — Video self-modeling: An individualized strength-based strategy for supporting the independent transitioning of a child with Autism Spectrum DisorderRésumé
Children with Autism Spectrum Disorder (ASD) frequently experience difficulties in situations that involve change within their environment and/or changes to their daily routine, and this often manifests in resistance to change. Transitions occur numerous times a day and across multiple settings. The aim of this study was to evaluate the efficacy of Video Self-Modeling (VSM) to support the independent transitioning of a 9-year-old child with ASD who struggles with morning transitions in her home. Results indicated that VSM was highly effective in assisting this child to increase the frequency of independent transitions while simultaneously decreasing the number of challenging behaviours … Lire la suite

2019 — Informing the Development of an Internet-delivered Mental Health Program for Youth with Cystic Fibrosis: A Qualitative StudyRésumé
Youth with cystic fibrosis (CF) and their parent caregivers have been shown to experience elevated psychological symptoms. The need to address these issues through providing appropriate information and services to this population is evident. At present, there is no specific mental health program designed for youth with CF in Canada. The current study qualitatively examined the information and service needs of youth with CF. Participants (n = 16) included five youth with CF (Mage = 9.40, SD = 1.01), seven parent caregivers (Mage = 36.43, SD = 3.46), and four CF health care professionals (Mage = 44.00, SD = 10.46) … Lire la suite

2021 — Oxidative Degradation of Diethanolamine Solvent Induced By Nitrogen Dioxide and Dissolved Materials in Post-Combustion Capture of CO2 From Industrial Exhaust Gas StreamsRésumé
Solvent degradation is a serious and well-known operational problem in the postcombustion CO2 capture process using amine-based solvents. It is caused by undesired side reactions between the amine and flue gas impurities such as oxygen, nitrogen oxides (NOx), sulfur oxides (SOx), and fly ash particulate, resulting in a significant decrease in performance and efficiency as well as an increase in operational costs for solvent management. In addition, there are human and environmental concerns regarding the emergence of carcinogenic compounds, N-nitrosamines, which are contributed by the reaction between secondary amines and NOx in the flue gas. Moreover, heavy metalcontaining compounds from … Lire la suite

2023 — Understanding hadronic mass through light meson structure at the EICRésumé
The Electron-Ion Collider (EIC) is a new US $2 billion high-luminosity accelerator that is expected to be operational at BrookhavenNational Laboratory (BNL), USAat the beginning of the next decade [1]. One of the main goals of the EIC is to understand the origin of hadronic mass, this is the majority of visible mass (¡99%) in the universe. Based on current understanding, it is known that the mass of these systems is intricately connected to their internal structure. To understand this structure, and therefore these hadronic mass generation mechanisms, one of the simplest ways to examine the lightest hadronic systems such … Lire la suite

2015 — The Effect of Food Supplementation on the Territorial Behaviour of a Nocturnal Bird: The Common Poorwill (Phalaenoptilus Nuttallii)Résumé
When animals have more energy available to them, they should be able to spend more time on other activities such as territory defense because they are able to spend less time searching for food. Most studies examining this relationship have been on diurnal organisms where the time available for these activities is quite long. In contrast, the focus of my study is on a visual-hunting nocturnal species where the time available each day is much shorter because of the constraints imposed by reductions in ambient light. I examined the influence of food availability on the territorial behaviour of the insectivorous … Lire la suite

2015 — Children's Mathematics Anxiety and Its Effect on Their Conceptual Understanding of Arithmetic and Their Arithmetic FluencyRésumé
Research shows that children’s mathematics anxiety negatively impacts their performance on mathematics tests (e.g., Chernoff & Stone, 2012). However, no research to my knowledge has investigated how children’s mathematics anxiety impacts their conceptual understanding of arithmetic. The current study investigated the characteristics and development of Grades 4, 5, and 6 children’s mathematics anxiety and how it impacts their conceptual understanding and application of arithmetic using arithmetic concepts. For comparison, the current study also investigated how children’s mathematics anxiety impacts their arithmetic fluency using timed mathematics tests. As an exploratory and secondary component, the current study examined teachers’ mathematics anxiety and … Lire la suite

2019 — Children’s Mathematics Anxiety and Their Arithmetic Fluency: How Do Teachers and Parents Play A Role In Their Development?Résumé
The acquisition of mathematical skills in elementary school has an important role in future academic and professional success. These skills depend not only on cognitive abilities but also on emotional factors, such as mathematics anxiety (MA). MA is defined as feelings of tension that “interfere with the manipulation of numbers and the solving of mathematics problems in a wide variety of ordinary life and academic situations” (Richardson & Suinn, 1972). Once formed, MA is difficult to change and can persist well into adulthood. This is concerning as MA is negatively correlated with mathematics performance (MP). Aside from MA, little research … Lire la suite
