2022 — Magic is might?: Uncovering abjection in Shakespeare's The Tempest and J.K Rowling's Harry Potter seriesRésumé
This thesis begins with an analysis of the two focal point statues in the Ministry of Magic from the Harry Potter series: The Fountain of Magical Brethren and the Magic is Might statue. This analysis prompts the questions that this thesis will answer: how does magic create might if it is contingent on never completing the acts that represent that might? Furthermore, how is this system created and how is this system upheld if it is not able to fully get rid of the challenges to its order? In answering these questions, this thesis will not only look at the … Lire la suite

2023 — Drag-and-drop query refinement and query history visualization for mobile exploratory searchRésumé
Search plays a crucial role in digital public libraries due to the vast amount of information available to users. These users often require support because their search tasks are inherently complex. Complex search tasks, characterized as ill-defined, open-ended, or multi-faceted, occur when the information need cannot be satisfied by simply finding a single optimal resource; searchers are required to revise, refine, and reformulate their queries multiple times. One challenge that users face is how to refine their queries. This challenge is compounded when using a mobile device, where typing is time-consuming and error-prone. Conducting searches in a mobile context adds … Lire la suite

2012 — Transformations: Treatment for Alcohol Addiction as a Process of Consciousness ExpansionRésumé
A body of research has suggested that an understanding of the lived experience of addicted individuals is an important yet neglected part of developing effective treatments for addictions. In an attempt to further understand the subjective experience of addiction, a phenomenological study was undertaken with the aim of understanding if consciousness studies could inform and enrich current treatments for addiction. Specifically, the study examined the utility of conceptualizing an addiction as a problem of restricted consciousness and its treatment as a process of consciousness expansion. This study attempted to further understanding related to changes in consciousness, and the development of … Lire la suite

2019 — Techno-Economic Analysis and Life Cycle Assessment of Large Scale Biogas to Methanol ProductionRésumé
The development of renewable energy products is essential as the world progresses toward sustainability. Renewables are energy collected from sources, which are filled naturally on a human scale. On the other hand, it is impossible to renew non-renewable energy sources only after several hundred million years, leading to many problems, including but not limited to environmental contamination, issues in public health, rising costs and their enduring lifetime. For example, after several hundred million years, when the earth's supplies of fossil fuel get exhausted, it cannot be renewed. This study focused on a techno-economic analysis and life cycle assessment of using … Lire la suite

2020 — A Grounded Theory Analysis of a Trauma-Sensitve Yoga Intervention for Paramedics within an Indigenous Cultural Responsiveness FrameworkRésumé
Paramedics have high levels of posttraumatic stress. It is estimated that approximately 22% or more than one-fifth of Canadian paramedics in the profession of paramedicine will be affected by posttraumatic stress disorder (PTSD) (Drewitz-Chesney, 2012). Individuals experiencing PTSD have difficulty with self-regulation, experiencing states of hyper- or hypo-arousal (van der Kolk, 2001). It has been suggested that in the recovery from trauma it is essential to allow the presence of uncomfortable bodily sensations and emotions (van der Kolk, 2001). Mindfulness training (of which yoga is a form) is recognized by experts in trauma treatment as an effective approach to selfregulation … Lire la suite

2022 — Professional Practice Competencies of Social Workers Employed in Mental Health and Addiction Settings within Saskatchewan: A Phenomenological InquiryRésumé
Historically, competencies have been viewed to primarily capture practice knowledge, core behaviors and skills needed in a wide range of professions. Holistic competence is a multidimensional model that refers to practice-based competencies such as knowledge, skills and abilities but also includes a set of higher-level competencies or meta-competencies such as self-reflection, professional judgement, and self-confidence. The most critical component of meta-competencies is self-reflection. However, there are gaps in research related to holistic competencies used by frontline social work practitioners. The purpose of this descriptive phenomenological approach was to explore the perceptions and attitudes related to self-reflection among social workers who … Lire la suite

2019 — Vulcanoids: An Examination of the Intra-Mercurial RegionRésumé
A review and discussion of the historical and modern ideas pertaining to the vulcanoid region of our solar system, and the theoretical asteroid population therein is presented here. Current observations constrain the maximum possible vulcanoid object size to somewhere between 5 and 10 km in diameter. Any object larger than this located within the putative vulcanoid zone, the region 0.06 AU to 0.25 AU away from the sun, should have been observed in past observations. With this in mind any modern day vulcanoid population would be small in number and size, but as yet, there is no compelling reason to … Lire la suite

2012 — Cognitions in Non Life-Threatening Traumatic EventsRésumé
Posttraumatic stress disorder (PTSD) is a debilitating condition associated with diffuse impairment and distress. The onset of PTSD requires a traumatic stressor, an event in which an individual experienced or was confronted with death, serious injury, or threat to bodily integrity. An emerging research literature has demonstrated that some stressors, while not necessarily life-threatening (e.g., divorce), may provoke intense posttraumatic stress reactions and hallmark PTSD symptoms (e.g., flashbacks, sleep disturbance, emotional numbing; Carleton, Peluso, Collimore, & Asmundson, 2011). Associations between experiencing PTSD-like symptoms in response to non lifethreatening stressors have been documented; however, this area remains both controversial and relatively … Lire la suite

2011 — Comparison of Three Dimensional Measurement Accuracy Using Stereo VisionRésumé
The stereo vision system has been widely used in recent years. The imaging process of a camera consists in projection from a three dimensional world to a two dimensional image in which one dimension of information has been lost. A vision system that consists of two cameras can use the implicit geometry constraint between the images to recover the three dimensional information. Thus, the stereo vision system can be used as a measuring tool. A few applications have been reported and some of them are included by the literature review. In this thesis, two parameters of the stereovision system have … Lire la suite

2016 — Experimental Study on Improving the Waterflooding Potential in Different Heavy Oil-Solvent SystemsRésumé
Due to the unfavourable mobility ratio of heavy oil and water, waterflooding cannot be used successfully without the support of natural energies (such as solution gas drive, foamy oil effect, expansion effect, etc.) in heavy oil reservoirs. In previous studies, the parameters related to the pressure change, such as the injection rate, the start time of waterflooding, the voidage replacement ratio (VRR) control, etc., have been studied to take full advantage of the nature energies in heavy oil waterflooding processes. However, few researchers have directly studied the pressure control strategies to improve the waterflooding potential in heavy oil reservoirs. Meanwhile, … Lire la suite

2021 — Pore-Scale Imbibition Studies for Tight Rock SystemsRésumé
Imbibition pervasively exists in many natural and industrial processes, such as oil/gas recovery, hydraulic fracturing, the postinjection stage of CO2 sequestration, printing processes, diagnostic tests in biomedicine. As a dominant mechanism in tight formations, imbibition has been extensively studied across scales to support world energy demands and environmental requirements of carbon neutrality. Many studies indicate that macroscale performances, like the displacement front instability and residual saturation of the non-wetting phase, highly depend on flow behaviors at the pore-scale level. Despite the importance of pore-scale imbibition processes in tight rocks, many previous studies have been conducted lack considering typical pore-throat features … Lire la suite

2015 — High-throughput Functional Genomic Screening using Saturating Transposon Mutant Libraries and Next Generation Sequencing in Rhizobium leguminosarumRésumé
To increase the rate of scientific discovery in the Rhizobiaceae family of bacteria there is a need to adapt high-throughput genetic screens like insertion sequencing. Here we describe the adaptation of a Rhizobiaceae-compatible MmeI-adapted mariner transposon, from a previous vector pSAM_Bt, that can be used with insertion sequencing for highthroughput forward genetic screening. The newly constructed mariner transposon pSAM_Rl mutagenized R. leguminosarum, S. meliloti, and A. tumefaciens at a high frequency. In R. leguminosarum, two high-throughput forward genetic screens were performed with the vector to identify genes involved in proper cell growth on complex and minimal media. Mutant pools of … Lire la suite

2022 — Examining Motivational Interviewing and Booster Sessions in Internet-Delivered Cognitive Behaviour Therapy for Post- Secondary Students: An Implementation TrialRésumé
Approximately one in three post-secondary students experience clinical levels of anxiety or depression during their academic career, with many students not receiving treatment. Internet-delivered cognitive behaviour therapy (ICBT) is an alternative to face-to-face services that is effective in general adult populations, but has been associated with high attrition rates and smaller effect sizes in student populations. In this implementation trial, the efficacy and uptake of an ICBT course for anxiety and depression (i.e. the UniWellbeing Course) was examined in Saskatchewan. Given the evidence from the face-to-face literature, the role of motivational interviewing (MI) and booster lessons was also examined. Using … Lire la suite

2019 — Perceptions Of and Preference For Internet-Delivered Cognitive Behaviour Therapy Among Post-Secondary StudentsRésumé
Background: Post-secondary students experience elevated rates of mental health concerns, including anxiety and depression. These mental health concerns often contribute to the stress experienced by students, and interfere with social and academic functioning. Most colleges and universities have some form of mental health support for students, often in the form of campus counselling centers. However, these services often offer a limited number of sessions per student and are reported to have difficulties meeting the mental health demands of students. Students face several barriers when seeking psychological help, including stigma, lack of time, financial constraints, and perceptions that their mental health … Lire la suite

2013 — Simulation Study of Distillation, Stripping, and Flash Technology for an Energy Efficient Methanol Recovery Unit in Biodiesel Production ProcessesRésumé
Biodiesel is an important alternative renewable energy source currently produced by transesterification reaction of oil or fat with methanol. To improve the conversion, excess methanol is required, which must be recovered from the product stream and recycled back into the process for further biodiesel production. The intensive energy requirements for methanol recovery are an important issue that directly impacts the production costs of biodiesel. To reduce the cost of biodiesel production, an energy efficient methanol recovery unit (MRU) is crucial. This work focuses on energy requirement reduction by distillation, flash-based recovery, and newly-introduced stripping-based methanol recovery units. Four different continuous … Lire la suite

2024 — Development of task specific ionic liquids incorporated porous sorbents for post-combustion CO2 captureRésumé
Amino functionalized ionic liquids (AAILs), also known as task-specific ionic liquids (TSILs), have demonstrated CO2 capture ability similar to amines while maintaining ionic liquid properties such as low regeneration energy, volatility, and thermal stability. However, high synthesis costs and viscosity prevent their broad usage in CO2 capture technologies. Recently discovered porous materials like metal-organic frameworks (MOFs) and ordered mesoporous silica have stimulated scientists’ interest in CO2 capture applications. However, these materials have limited CO2 absorption and poor CO2/N2 selectivity, particularly at post-combustion CO2 capture conditions (0.15 bar). Immobilizing TSILs in solid pores to boost CO2 capture is an innovative way … Lire la suite
