2019 — Determination of Endocrine Disrupting Chemicals in Water and Wastewater in SaskatchewanRésumé
A liquid chromatography-negative ion electrospray ionization-tandem mass spectrometry (LC-ESI--MS/MS) method was developed for the simultaneous analysis of endocrine disruptive chemicals including bisphenol A, 4-octylphenol, 4-nonylphenol, diethylstilbestrol, 17-β-estradiol, estriol, estrone, 17-α-ethinylestradiol, prednisone and prednisolone. Mass spectrometric detection of these target analytes is sensitive to the presence of additives in the mobile phase as well as those used in the sample preparation steps. To avoid issues with reduced mass spectrometry sensitivity, the sample preparation involved elution of the target analytes from the solid-phase sorbent with acetonitrile, drying, and reconstitution with methanol, water, and 2-propanol. Recoveries for all the analytes were from 82.4 … Lire la suite

2019 — Measuring the Abundance of Antibiotic Resistant Bacteria and Mobile Antibiotic Resistance Plasmids Within Human Impacted EnvironmentsRésumé
The spread of antibiotic resistance genes in the environment has become a worldwide concern in recent years. Horizontal gene transfer (HGT) is a process that can facilitate the spread of antibiotic resistance genes (ARGs) among bacterial communities. Often, ARGs are carried on mobile genetic elements (MGEs) such as plasmids which are able to transfer those genes among bacterial species via conjugation. Monitoring the transfer rate of ARGs using a defined recipient strain in conjugation experiments can provide further insight into environmental factors that can impact the abundance of mobile ARG plasmids, in managed environments. I used E. coli J53 and … Lire la suite

2019 — A Study of Antibiotic Resistance Plasmids in Fresh Produce and In Wastewater Environments Using Functional Approaches, Comparative Genomics and Abundance AnalysisRésumé
Studies have shown that a major reservoir of clinically relevant antibiotic resistance genes (ARGs) is found in non-pathogenic environmental bacteria. Ciprofloxacin, meropenem and erythromycin are important clinical antibiotics due to their broad applications in the treatment of Gram-positive and Gram-negative infections. The capacity to capture, mobilise and control the expression of resistance genes is an important factor in the development of multidrug resistance and the mobilome (the community of mobile genetic elements) is responsible for its genetic plasticity. Plasmids are important constituents of the environmental mobilome. The capacity to replicate independently of the bacterial chromosome coupled with the ability to … Lire la suite

2019 — Assessing the Effectiveness of Results-Based Reulations in Fostering Innovation and Social Learning: A Focus on the Saskatchewan Ministry of EnvironmentRésumé
Results-Based Regulation (RBR) is a hybrid regulation that incorporates some features of a prescriptive regulation, outcome-based regulation, and co-regulation. Traditionally, the environmental activities in Saskatchewan were administered through prescriptive regulation. In 2015, RBR was introduced to substitute the prescriptive regulation. When RBR was introduced, some notable changes were made, and some expected outcomes were stipulated. The core changes that shaped this thesis include the introduction of ‘alternative solutions’ when complying with the regulation, reliance on qualified persons (QP) to certify alternative solutions, and a focus on results. The emphasis on results and the provision of alternative solutions were expected to … Lire la suite

2019 — Summarizing Conditional Preference NetworksRésumé
Preference modeling has been studied extensively in the literature, and has applications in recommender systems and automated decision-making. The eventual objective of working with preference models is to be able to reason about preferences over objects, often referred to as outcomes. In most of the literature, each outcome is described as an assignment of values to a set of attributes. Representing and reasoning about preferences over outcomes calls for efficient preference models. In this thesis, we focus on one such model, Con- ditional Preference Networks (CP-nets). A CP-net is a graphical model that captures the preferences of an individual using … Lire la suite

2019 — Machine Learning for Shill Bidding Classification ModelsRésumé
As online auctions become more prevalent worldwide, they are increasingly targeted by various types of cyber-crimes. In-auction fraud, such as shill bidding (SB), is considered the most challenging to detect. SB has been recognized as the predominant form of online auction fraud. It is di cult to identify due to its similarity to normal bidding behavior. The complexity of nding and de ning SB patterns makes it resistant to discovery. Also, the unavailability of SB datasets that are based on actual e-auctions makes the development of SB detection and classi cation models challenging. Therefore, the prerequisite task that is necessary … Lire la suite

2019 — “So What Happened to You?” A Pilot Study Examing the Impact of Ableist MicroaggressionsRésumé
Microaggression involves seemingly innocent, subtle, and brief discriminatory behavior that can have a detrimental impact due to its omnipresent perpetration against members of marginalized groups. Microaggressions perpetrated against individuals with disabilities are often rooted in ableism. Ableism refers to the belief that anyone who does not fit into able-bodied norms is not worthy of equal treatment. Further, ableism perpetrated by institutions creates an environment in which institutional betrayal is fostered. Institutional betrayal has been shown to exacerbate the negative effects of trauma or discrimination. The present study was designed to investigate the immediate impact of an ableist microaggression on individuals … Lire la suite

2019 — Estimation of Weed Densities for Variable Rate Herbicide ApplicationRésumé
Use of herbicides is rising globally to maximize crop yield and profitability. Herbicides negatively impact environmental health and biosphere. To lessen its negative effects, herbicides have to be applied judiciously on crops. Precision agriculture practices suggest adoption of site specific weed management techniques by exploiting patchy nature of weed distribution in the fields which requires accurate weed mapping. Despite recent technical advancement and growing awareness about environment protection, site specific weed management has not got traction in farmer community. In this thesis, endeavours are made to develop relatively simple site specific weed control method using weed density based variable rate … Lire la suite

2019 — Characterizaion and Chemical Rescure of the Phenotype of ors-3, a Knockout mutant line of PpORS in Physcomitrella patensRésumé
2ʹ-Oxoalkylresorcinol synthase from Physcomitrella patens (PpORS) is basal to all plant type III polyketide synthases in phylogenetic trees, and may resemble closely their most recent common ancestor. PpORS knockouts were previously generated and partially characterized (Li et al., Planta, 2018, 247: 527–541). This study aimed to investigate further the in planta functions and evolutionary roles of PpORS. Ors-3 (an ors knockout line) was first subjected to dehydration stress. The ability of ors-3 to recover after dehydration is significantly compromised in contrast to the control strain. Ors-3 also loses water faster than the control strain. These results together with the previous … Lire la suite

2019 — Measurement of the Beam Asymmetry for the ETA and ETA Prime Mesons with the Gluex ExperimentRésumé
The GlueX Experiment in Hall D at Jefferson Lab ultimately aims to provide evidence of hybrid mesons, quark-antiquark pairs with gluonic excitations, which are predicted by quantum chromodynamics calculations on the lattice. GlueX features a linearly-polarized photon beam incident on a liquid hydrogen target and a nearly-four-pi hermetic detector capable of measuring positions and momenta of both charged and neutral final state particles generated in the target. The short-term physics goals of GlueX are to measure observables and properties of the known particles, especially those that are likely decay products of hybrids, such as the eta and eta-prime mesons.

2019 — An Auto-Picking Algorithm For The Detection of Clay Seams In Potash Mines Using GPR DataRésumé
Potash mines can be in operation for up to one hundred (100) years. Maintaining a stable mine roof is critical for the safety of current and future underground mine operations. Visual clues on side walls, combined with the historical knowledge of the ore formation in a particular region, provide a primary but inconclusive identification of the presence and distance of clay seams from the mining zone. Clay seams are a weak point of possible failure and as such, a buffer distance needs to be maintained between the clay seam and the mining roof. In addition to safety, knowledge of the … Lire la suite

2019 — The Roles of Language in Childrens Snake Aversion and CategorizationRésumé
Snake aversion and vilification is widespread in human society, but does not reflect the danger that snakes typically pose to humans. Recent research indicates that snake aversion is likely not innate, but somehow learned. Language used to describe atypical animals often differs than language used to describe more typical animals. Parents are also more likely to use prohibitive language such as “Don’t get too close to that!” when referring to snakes but not to other animals like hamsters (even when the animal is enclosed). Since the language used to describe animals has been shown to change the way that children … Lire la suite

2019 — Facet-Time: Using Information Seeking Strategies to Support Exploration of Time Series DataRésumé
The notion of time has important value in people’s lives. By analyzing timeoriented data, we can understand underlying trends in the data. Graphically representing the data is useful for analysis because a single visualization can represent much information. Some tools providing visualizations for time-series data are well supported for lookup tasks; however, their support for exploratory search tasks are minimal. In exploratory search tasks, users may not have a specific search goal or they may have ill-defined information needs. They usually learn by iterating through and interpreting search results and perform investigation over them before integrating the obtained information into … Lire la suite

2019 — Alzheimer's Disease and Amyloid Beta: Effects of amyloid beta on hippocampal and dorsal root ganglion neurons' electrophyiology and morphologyRésumé
Alzheimer’s disease (AD) is the most common type of dementia, increasing by 10 new cases every day in Saskatchewan alone. AD results from pathological amyloid beta (Aβ) peptides that hamper neurons’ communication, cause progressive neuronal cell death in the central nervous system, and ultimately lead to memory loss in the individual. While disease symptoms are well known, the mechanism by which Aβ triggers the degeneration of the brain remains elusive. There is no cure for AD and present treatments only focus on slowing down the disease progression or mitigating symptoms. This study has used several techniques to investigate the effect … Lire la suite

2019 — Burnout and Mental Well-Being in Higher Education: Investigating the Impact of Multicultural EfficacyRésumé
Canadian universities are experiencing a dramatic increase in the enrollment of students from diverse backgrounds. Many educators are not prepared to teach in multicultural contexts. Educators’ lack of preparedness to teach in such contexts may lead them to develop burnout, which can negatively impact their mental and professional well-being. However, self-efficacy beliefs (i.e., judgements of personal capabilities in executing a specific task successfully) may buffer against job burnout and promote mental wellbeing. Hence, multicultural efficacy, defined as the confidence to teach diverse students effectively, is an important factor for teaching in multicultural settings. Limited studies have investigated the impact of … Lire la suite

2019 — Quantification of Phase Behaviour and Physical Properties of Solvents-Heavy Oil/Bitumen-Water Systems at High Pressures and Elevated TemperaturesRésumé
Due to the excess heat loss of steam assisted gravity drainage (SAGD) processes and low oil production rate of solvent-based processes, the expanding solvent SAGD (ES-SAGD) process has been considered as a promising technique for enhancing heavy oil/bitumen recovery. The main ES-SAGD mechanisms include the heat transferred and dissolution of solvents into the heavy oil/bitumen to swell it and reduce its viscosity, which is closely related to the phase behaviour of solvents-heavy oil/bitumen-water systems. Thus, it is of fundamental and practical importance to accurately quantify the phase behaviour and physical properties of the aforementioned systems. A pragmatic technique has been … Lire la suite

2019 — Rank Distribution of Linear Maps and Proportion of Indecomposable RepresentationsRésumé
The distribution of the ranks of all linear maps between two nite-dimensional vector spaces over a eld of order q is determined both theoretically and experimen- tally. The distribution is derived by using a particular group action on the set of rectangular matrices with entries from a eld of order q and then applying the orbit- stabilizer theorem. In addition, the proportion of vectors in the kernel of a linear map based on its image dimension is determined and used to experimentally determine the rank of a linear map. Moreover, the proportion of the indecomposable representations in the functor category … Lire la suite

2019 — The Effects of Mild Bilateral Jugular Vein Compression on Cerebrovascular PhysiologyRésumé
Cerebrovascular physiology is a branch of study surrounding the relationship between the brain and heart. This relationship is critical for health, performance, and survival and must be maintained in a metabolically balanced state to prevent any adverse effects. Recently, there have been efforts by groups of researchers to challenge this system via external jugular vein compression to investigate the effect of brain blood-flow and hemodynamics. So far positive outcomes using the Q-Collar™ have been observed in neuroanatomical and neurophysiological studies. However, there has yet to be validation of Q-Collar™ use through real-time monitoring of cerebrovascular physiology, specifically during acute exercise. … Lire la suite

2019 — The Decision to Use Eye Movement Integration Therapy: Exploring Clinicians' Experiences Through A Narrative InquiryRésumé
Evidence based practice (EBP) suggests that the best source of evidence to guide clinical decisions comes from randomized control trials; however, many practicing clinicians view client outcomes, clinical experience and their feelings of confidence using an intervention as the best sources to make clinical decisions. In the treatment of Post Traumatic Stress Disorder (PTSD) there are interventions that have been deemed to be EBP however, what has been found is many clinicians do not use EBP to treat trauma. Eye Movement Integration Therapy (EMI) is an example of an intervention used to treat PTSD that is not deemed an EBP. … Lire la suite

2019 — Quantification of Mutual Mass Transfer of Gas-Light Oil Systems at High Pressures and Elevated TemperaturesRésumé
Numerous tight oil resources that are characterized by both low porosity and permeability have been found in North America during past decades. Due to the extremely low permeability, water injection has found its limitation with its relatively low injectivity. Alternatively, gas injection, such as CO2, N2, hydrocarbon gas, and flue gas, has been made physically possible for enhancing oil recovery under certain conditions, during which molecular diffusion is of great importance. Due to the affordability and sustainability of CO2, N2 and flue gas have been found to be costeffective for enhancing hydrocarbon recovery to a certain extent. Physically, there exists … Lire la suite

2019 — How Do Parliamentarians Use ICTs?Résumé
Parliamentarians have many responsibilities, both in the legislative chamber and in their constituencies. From participating in house and committee deliberations, to proposing legislation or amendments to other proposed bills, and speaking on behalf of and defending the interests of their electors, parliamentarians are supported by the resources of the body that administers parliament. In the digital era, these resources usually include information and communication technologies (ICTs) that facilitate these important and challenging tasks and support parliamentary transparency and legislative functions. However, little is known about how parliamentarians currently use ICTs to accomplish their goals. This research assesses how parliamentarians in … Lire la suite

2019 — The Evolution of Feminism in Nigerian Media: A Look At IGBO Culture FilmsRésumé
This thesis addresses the subject of feminism in the Nigerian media, particularly on how issues related to women’s rights and gender discrimination have been addressed in Igbo culture Nigerian films. For several decades, the Nigerian home video industry, dominated by Igbo culture-themed films, has been one of the most influential media forms across Nigeria and Africa in general. These films are a staple in many homes; the images, narratives, and ideas that they disseminate go a long way in shaping or reinforcing public perceptions about the role of women and their status in society. Taking a critical look at how … Lire la suite

2019 — The Influence of Hormonal Fluctuation on Stress-Induced Smoking Cravings in WomenRésumé
Women experience greater difficulties in quitting smoking, though the hormonal factors contributing to this sex difference remain to be clarified. Increased smoking has been observed in the late luteal phase of the menstrual cycle and the current study aimed to clarify the role that changes in reproductive hormones may play in explaining these cycle effects. Furthermore, it tested the hypothesis that stress-induced smoking cravings are more pronounced during the luteal phase. To this end, twenty-two smoking women underwent two laboratory sessions–one in the mid-follicular phase and the other in the late luteal phase–involving an in-vivo smoking cue task, administered before … Lire la suite

2019 — An experimental study of nanoparticle-assisted waterflooding in a heavy oil reservoirRésumé
Over the past decade, nanoparticles (NPs) have been tested to assist waterflooding (WF) for enhanced oil recovery (EOR) due to their superior physical and chemical properties. Majority of the previous studies used silicon oxides (SiO2) coated with polyethylene glycol or silane and other metallic oxides as NPs. In this study, a nanofluid (NF) was first characterized in terms of its bulk and interfacial properties, which comprised NPs dispersed in an aqueous phase. Second, the NP loss in a porous medium because of adsorption was measured. Third, a series of NP-assisted WF tests were conducted to measure the heavy oil recovery … Lire la suite

2019 — handwringersRésumé
Lying on his couch, reflecting on his life, Moses E. Herzog “thought awhile of Mithridates, whose system learned to thrive on poison. He cheated his assassins, who made the mistake of using small doses, and was pickled, not destroyed. Tutto fa brodo” (Bellow 4). Saul Bellow’s titular character offers an excellent metaphor for a complicated figure: the schlemiel. Herzog reflects on Mithridate’s inability to die with honor: having fortified himself against poisoning, he botches his suicide. The Italian phrase Bellow uses to describe Herzog’s state of mind is an idiom meaning literally “everything makes broth” suggesting that every little bit … Lire la suite

2019 — Women Teachers' Experiences Regarding Maternal Bodies, Maternity Leave, and Returning to WorkRésumé
In 2017, I became pregnant with my first child and I became overwhelmed with questions regarding my professional and personal identity. After confiding in others, I understood that numerous women felt strong emotions regarding their pregnancies and maternity leaves. I then began to think about how women teachers are treated during, and after pregnancy and maternity leave. There is a dearth of research on women’s interpretations of pregnancy based employment discrimination and felt the need to research this topic. Despite federal, provincial, and local policies that are to protect pregnant women in the work place, I found that women are … Lire la suite

2019 — Influence of Temperature and Water Quality on Physiological and Behavioral Responses of Walleye at Catch and Release Angling TournamentsRésumé
Walleye (Sander vitreus) is one of the most sought after freshwater fish for recreational angling in Canada. Physiological and behavioral measures of stress were used to determine if reduced live-well temperatures and improved water conditions can mitigate stress and facilitate recovery during catch and release angling tournaments. Fish were collected at tournament weigh-in stations to evaluate the effects of live-well water quality parameters and stress mitigation methods on recovery. Fish condition was assessed by measuring plasma cortisol and lactate levels, and observing behavioral cues. This study observed body flex, tail grab, and swim scores and these were determined valuable predictors … Lire la suite

2019 — Strategic Risk-Taking In The National Football League: A Multi-Level Model Analysis of the Relative State ModelRésumé
Risk-sensitivity theory suggests that decision-makers should choose high-risk (i.e., high outcome variance) options when low-risk options are unable to meet desired goals or outcomes. Experimental results supporting risk-sensitivity theory have been well documented and account for a significant portion of the variance in decision-making under risk (reviewed in Mishra, 2014). However, substantial evidence suggests decision-makers exhibit stable individual differences in risk-taking across context. The relative state model (Mishra, Barclay, & Sparks, 2017) consolidates these differences by positing that risk-taking is a product of one of two interrelated pathways: 1) a need-based pathway characterized by decision-makers acting on disparity between the … Lire la suite

2019 — Jesus Christ Superscribe: Knowledge, Interpretation, and Teaching in the Gospel of MatthewRésumé
Jesus-characters are most often created as a reflection of their authors, and the author/s of the text traditionally known as “The Gospel According to Matthew” is no different. Matthew creates a Jesus that is focussed on knowledge retention, interpretation, and dissemination. Throughout the text, they set up different scribe-characters as foils for Jesus, so that Jesus’s superior ability to interpret and teach the Hebrew writings can be displayed. Like ben Sira, Matthew creates an “ideal scribe” in their Jesus, and also displays the characteristics of the “ideal scribe” in the composition of the text. This scribe is an able teacher, … Lire la suite

2019 — Feasibility Analysis and Optimal Design of the Acidizing of Coalbed Methane WellsRésumé
Plugging is a prominent cause of reduced production in coalbed methane (CBM) wells. In this thesis, the feasibility analysis and optimal design of the acidizing of CBM wells to remove the plugging are researched. First, X-ray diffraction analysis shows that the plugging contains acid-soluble minerals and a field case indicates that the acidizing effect is positively correlated with the content of acid-soluble minerals. Inspired by this, the author analyzes influencing factors of the content of acid-soluble minerals. Well logging parameters (DEN, AC, GR) are selected to establish a neural network model to predict the content of the acid-soluble minerals. Furthermore, … Lire la suite

2019 — Examining the Role of Intolerance of Uncertainty in the Experience of PainRésumé
The pain experience is impacted by physical, psychological, and social factors (Asmundson & Wright, 2004). Symptoms of anxiety and related disorders have been associated with varied pain syndromes, particularly chronic pain (i.e., pain lasting longer than 3 months [International Association for the Study of Pain, 1994]; Asmundson, Norton, & Vlaeyen, 2004a). Chronic pain models implicate pain-related fear and anxiety as leading to activity avoidance, impeded healing, and prolonged pain (Asmundson et al., 2004a; Vlaeyen & Linton, 2000). Indeed, researchers have focused on pain-related fear and anxiety, and anxiety sensitivity (AS) as key risk factors for chronic pain (Carleton & Asmundson, … Lire la suite

2019 — Exploring The Perspectives of West African Immigrant Families on Active Living Among Adolescent Children: A Grounded Theory of StudyRésumé
Accumulating evidence suggests that the risks of inactivity-related problems such as obesity are becoming a population health concern among younger age groups. High income countries show an elevated rate of physical inactivity among children. Low- and middle-income countries are beginning to experience a gradual increase in this trend. Canada is a highly industrialized multicultural society with nearly 22% of foreign-born individuals coming through the immigration process. Recent immigrants tend to experience a decline in their health status, over time as their years in Canada increase (negative acculturation effect). This phenomenon can be attributed to several factors including adaptation to the … Lire la suite

2019 — Rodent Responses to Land Modification for Agriculture: Implications for Trophic Dynamics In the Northern Great PlainsRésumé
My thesis examines rodent species responses to agricultural land modification and their implications for trophic dynamics on the northern Great Plains. I first validated owl pellet analysis as a landscape-level sampling method for small mammal studies by comparing mammal diversity and composition between owl pellets and trapping from 27 studies of 15 owl species. Then using a dataset of >10,000 owl pellet samples collected from landscapes varying in agricultural intensity, I estimated rodent species responses to habitat loss and fragmentation, predicting species would respond relative to their affinity for unmodified grassland habitat. I found species responded irrespective of grassland specialization, … Lire la suite

2019 — Evaluation of Different Recovery Mechanisms on an Oil Field With History MatchRésumé
Full field development for a sandstone reservoir of complex structure has been studied using PETREL for building geological model, Eclipse 100 for black oil simulator and Eclipse 300 for compositional simulator. The FZI method that was adopted in this study is a viable methodology to distinguish rock types in the reservoir. Distinguishing the rock types gave us the privilege to calculate the permeability in each grid cell based on the cell porosity and rock type. Initial water saturation was calculated for each grid cell using the J-function algorithm based on rock type. Relative permeability curves were distributed in the simulation … Lire la suite

2019 — Sequential Approaches to Three-Way Data AnalyticsRésumé
Data analytics is a process to discover useful information in data, draw valuable conclusions, and help users make wise decisions. In most occasions, the conclusions can be formally represented as decision rules in which the left-hand-sides describe conditions and the right-hand-sides give decisions. Ideally, given particular conditions and decisions, the decision rules are expected to indicate definite answers of yes or no. However, definite answers may not be easy to give due to incompleteness, uncertainty, and errors. In such situations, forcing to give definite answers may result in significant mistakes. Instead of bipolar options, a theory of three-way decision allows … Lire la suite
