2021 — Exploring Adaptive Functioning and Sleep Quality in Children with Congenital Heart DiseaseRésumé
Congenital heart disease (CHD) is one of today’s leading birth anomalies (Reller et al., 2008). Children with CHD are at risk for neurodevelopmental and adaptive functioning challenges (Cassidy et al., 2018; Karsdorp et al., 2017; Marino et al., 2012). In turn, sleep difficulties are common in children with CHD; in fact, sleep disordered breathing (a common type of sleep dysfunction) is associated with increased mortality for infants with CHD (Combs et al., 2018). This study is the first to prospectively examine adaptive functioning and sleep quality in children aged 1-3 years with CHD compared to typically developing participants living in … Lire la suite

2017 — Locke's Political MetaphysicsRésumé
Locke’s achievements in political theory have traditionally been viewed in isolation from his metaphysical and epistemological accomplishments. Consequently, many deformations of Locke’s view of the former and the latter have manifested; principal among these is the notion of an atheist and materialist Locke. The goal of the proceeding study is to show how in what I’ve termed, Locke’s “political metaphysics” we see the emergence of a politics that is a consequence of his metaphysical commitments to human beings as free persons. That freedom is understood by Locke, not merely positively, in what one does, or can be seen by others … Lire la suite

2018 — Responding to Urban Regulation: How Policies of Public Spaces Affect the Lifeworld of the Chronically Homeless in New Zealand and Alberta, CanadaRésumé
Public spaces are central places in a community where people will gather to socialize and discuss politics or other community matters. Formal regulations on public spaces, where bylaws can be seen as a way to control for desired behaviour, have been used extensively in many cities. These regulations have actively excluded certain individuals from urban settlements and they continue to do so to create a clean space that is safe. This thesis uses urban comparison to contrast the four different local authorities of Auckland and Wellington, New Zealand and Calgary and Red Deer, Alberta, Canada using the response of homeless … Lire la suite

2020 — Evaluation of Bioherbicidal Properties of Pseudomonas syringae pv. tagetis for Control of Canada thistle (Cirsium arvense)Résumé
Canada thistle (Cirsium arvense, family Asteraceae) is a particularly aggressive invasive plant species that is problematic in Canadian agriculture. It can be particularly challenging for organic farmers, as it cannot be eliminated using methods like tillage, due to its ability to regrow using adventitious shoots from root fragments. One strategy would be to use an organic bioherbicide. One bacterial pathogen that has been explored as a replacement for conventional herbicides is Pseudomonas syringae pv. tagetis, as it produces tagetitoxin, which causes chlorosis and stunting in plants of the Asteraceae. The objective of my thesis was to assess P. syringae pv. … Lire la suite

2013 — A Theoretical Model of Development Partnership and Identity: Sport-For-Development Partnership in Trinidad and Tobago,Résumé
Current development efforts focus on economic fair play, cultural sensitivity theory, locally driven interventions, and ethical practice. This has led to changes in a number of development areas, including the relationship between development stakeholders. A shift to development partnership was meant to signal the end of development paternalism (e.g., north-south, developed-undeveloped, donor-recipient) and the beginning of development equality. However, for many development stakeholders, the transition has been largely theoretical. This study addresses the existing gap between development theory and practice. It argues that before the gap can be closed there is a need for greater philosophicallygrounded theoretical scrutiny. Therefore, this … Lire la suite

2023 — "Ours is a history of adapting": An analysis of adaptive capacity to climate change in rural and small-town SaskatchewanRésumé
Climate scientists project that the Canadian Prairies will undergo increasing effects of climate change in the future, and indeed have already observed significant impacts. Scientists have projected rising temperatures, changing growing seasons, an increase in variability, and more extreme and frequent disasters such as fires, floods, and droughts throughout the next several decades. While not all communities in the Canadian Prairies are equally exposed to the impacts of climate change, social scientists have noted that vulnerability of communities to climate change is not determined by exposure alone. Vulnerability is conceptualized as a function of a community’s exposure to a climate … Lire la suite

2016 — Nikawiy: A Cree Woman's ExperienceRésumé
The purpose of this research was to identify the barriers and challenges faced by my mother, an Aboriginal woman of Cree descent, and to determine how she has survived despite the multiple oppressions she has faced. I sought to discover the experiences that contributed to her life story; identify coping mechanisms that contributed to her resiliency; and understand if her experiences could be situated in the context of the encounters of other Aboriginal women. Drawing on both Western and Indigenous research models allowed me to complete this research in a way that holds meaning for me as an Aboriginal academic. … Lire la suite

2012 — Farmers' Perceptions of the Effectiveness of Government Programming at the Ground Level: A Manitoba-Saskatchewan Case Study ComparisonRésumé
This thesis examines the perceived impact of agriculture programming at the ground level in the Rural Municipality of Albert in Manitoba, and the Rural Municipality of Storthoaks in Saskatchewan. It provides a description of agriculture as it was practiced in these communities in 2008, as well as an analysis of how producers perceived the outcome of three specific programs: the Canadian Agricultural Income Stabilization (CAIS) account, Production Insurance (PI) and the Environmental Farm Planning (EFP) program. The Agricultural Policy Framework, implemented in 2003, was the structure upon which these programs originated from. The research measures the effectiveness of the programs … Lire la suite

2012 — Oil Recovery Mechanisms and Asphaltene Precipitation Phenomenon in CO2 Flooding ProcessesRésumé
In this thesis, the mutual interactions between a light crude oil and CO2 at the reservoir temperature were experimentally studied. The oil recovery mechanisms and asphaltene precipitation phenomenon in tight sandstone reservoir core plugs during immiscible and miscible CO2 flooding processes were examined. Meanwhile, the physicochemical properties of the produced oils and gases during CO2 flooding processes were thoroughly characterized. Furthermore, numerical simulation was performed to history match the experimental oil production data for the miscible CO2 coreflood tests. In experiment, first, a visualized saturation cell was used to determine the onset pressure of the asphaltene precipitation (Pasp). Second, the … Lire la suite

2012 — Producing (White) Teachers: A Geneaology of Secondary Teacher Education in ReginaRésumé
Thinking about race in education, especially in the multicultural or even “postracial” context of 2012, is not an easy thing. A paradox exists: On the one hand, race is powerfully present in teachers, in teaching, and in school contexts; on the other, teachers, generally, are unable to think about their work and practices in the context of race. This dissertation explores this paradox by asking the following question: How does pre-service teacher education produce teachers as racialized subjects? This dissertation is informed by the Foucaultian methodology of genealogy and poststructural theories of subjectivity. Through genealogy, this work presents a cogent … Lire la suite

2016 — A coming together: The juxtaposition of the Rae and Hearne cratons along the Virgin River shear zone (Snowbird tectonic zone), Saskatchewan, Canada, and the implications for proto-LaurentiaRésumé
The Snowbird tectonic zone of western Laurentia remains an enigmatic feature; some researchers have suggested that it represents a Paleoproterozoic suture, whereas others have proposed that it represents a reactivated Archean intracratonic fault zone. The Virgin River shear zone is the most southwesterly exposure of the Snowbird tectonic zone, along which rocks of the southern Rae and southern Hearne provinces meet. The Rae craton is the hanging wall to the northwest-dipping structure. Rocks of the southwest Rae are an extension of the Taltson basement complex and the intrusive Taltson magmatic zone. The Taltson basement complex contains ca. 2460 Ma diorites … Lire la suite

2023 — Multiple independent lineups: A procedure for corroborating eyewitness identification evidence in childrenRésumé
Child eyewitnesses exhibit problematic choosing on police lineups at a higher rate than adults (Fitzgerald & Price, 2015), which is an issue as mistaken eyewitness testimony is a leading cause of wrongful convictions (National Registry of Exonerations, 2019). This study examined a novel eyewitness technique to use with children, the multiple independent lineup (MIL) technique, to assess facial identification accuracy. A total of 486 children (60% male, 39% female, and 1% other; Mage = 8.59) witnessed a live event and, the following day, engaged in a lineup identification task (i.e., single simultaneous face lineup or the multiple independent lineup technique). … 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

2022 — Systemic evaluation of mobile applications for informal caregivers of people living with dementiaRésumé
Informal caregivers of people living with dementia experience stressors that are associated with adverse health outcomes. Mobile applications (i.e., apps) could improve the delivery of and increase access to interventions. Although apps for informal caregivers of people living with dementia are available, empirical evidence to support their effectiveness is limited. This study was aimed at addressing these gaps in the research literature by providing a comprehensive review and evaluating the effectiveness of available apps for informal caregivers of people living with dementia. A systematic search and content analysis of available apps were conducted. Sixteen apps meeting criteria were analyzed in … Lire la suite

2016 — Planning and Optimization of Cellular Heterogeneous NetworksRésumé
Over the past few years there has been an dramatic increase in mobile data tra c demand, a trend that is expected to continue in coming years. Traditional macrocellonly networks are incapable of providing the quality of service that modern subscribers expect from a mobile broadband service. Increasing network densi cation with the deployment of low power base stations has proven to be an e ective solution in this regard. The resulting multi-tier topology is known as heterogeneous networks or HetNets. This new topology brings a series of new and important challenges, since traditional practices applied for macrocell-only networks no … Lire la suite

2014 — Relational Verbs: Paradigm and Practice in a Manitoba dialect of Swampy CreeRésumé
This thesis studies the verbal inflection in Cree called the relational form, with a focus on Western Cree dialects, primarily Swampy Cree as spoken in Kinosao Sipi (Norway House), Manitoba. I will overview previous literature on the topic, from early grammarians Horden (1881), Howse (1844) and Lacombe (1874) to more modern accounts from Ellis (1971, 2000, 2004), Junker (2003) and Wolfart (1973). As well, textual evidence will be discussed for the relational paradigm in Cree dialects from text collections and publications by Ahenakew (1987a), Bloomfield (1930, 1934), Ellis (1995), Kâ-Nîpitêhtêw (1998), Minde (1997) and Wolfart & Ahenakew (1992, 2000). Following … 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

2015 — Chloride Salts Removal by non Planted Constructed Wetlands Receiving Synthetic Brines from Belle Plaine Potash MiningRésumé
Four pilot-scale constructed wetlands (CWs) were employed to study the fate and transport of the two dominant chloride salts (NaCl and KCl) receiving the synthetic brine. The characteristics of the brine solution are made up with a 10:1 concentration ratio between NaCl and KCl based on data obtained from Belle Plaine potash mine site. The multi-layer soils were designed to function as a main salt filtering component comprising of Regina Clay (grain size <0.002 mm), Brick Sand (grain size <4.75 mm) and sharp gravels (grain size between 6.3-19.1 mm) despite the clay layers contained a poor compact condition (Db =1.4, <1.6 g/cm3). The volume of void space in the compacted clay was reduced to approximately half the natural state following application of pressure (4,505 cm3 to 2,743 cm3). The CW systems were operated by the 16-day format (batch 1-3) and the 4-day format (batch 4). During the 16-day format experiments, the best K+ removal rate was recorded on Cell2 as 92.1±63.4% (4.6±5.3mg/l) while Cell 4 contributed the maximum removal of Na+ and Cl- as 44.8±76.7% (53.2±92.4mg/l) and 50.5±109.6% (85.3±184.3.4mg/l). In the 4-day format operation, the chloride breakthrough curve was discovered in all treatment CW cells, excluding the control. Moreover, the curve stated at less than 6 hours (C/C0 > 0.05) and approximately reached the break point (C/C0 > 0.95) after passing 48 hours. Then the clay media was exhausted and lost its ability to remove Cl-. However, …</0.002> Lire la suite
