2023 — Classification of soil surface texture using high-resolution RGB images captured under uncontrolled field conditionsRésumé
Understanding the properties of soil and its impact on the environment and farming practices requires accurately classifying its texture. Accurate soil texture classification can optimize soil nutrient levels and improve land management. This study proposes a framework that uses images captured under Uncontrolled Field Conditions (UFC) to classify soil texture for farmlands accurately. UFC images are captured in varying ambient light and environmental conditions, which can introduce unwanted elements such as shadows and varying lighting. Our framework uses image-processing techniques, texture-enhancing methods, and deep learning to process and classify these soils accurately. First, we process the soil using semantic segmentation … Lire la suite

2017 — Winter Ecology and Ecophysiology of Prairie-Living Big Brown Bats (Eptesicus Fuscus)Résumé
Hibernation allows animals to survive lengthy periods of energetic deficit, but is not without costs. Hypometabolism, low body-temperature, and inactivity are associated with a variety of costs such as immuno-incompetence, dehydration, and build up of harmful metabolites. Additionally, conditions within hibernacula have a profound influence on hibernation patterns and survival. Periodic arousals and site selection are thought to mitigate these costs, and often involve timing arousals to foraging opportunities and overwintering in locations with stable temperatures and high humidity. I studied prairie-living big brown bats (Eptesicus fuscus) that overwinter in rock crevices and take flight outside of the hibernacula despite … Lire la suite

2017 — Nonlinear Dynamic Behavior of Single Walled Carbon Nanotubes with an Initial Geometric Imperfection Using Shell Elasticity TheoryRésumé
In this thesis, the nonlinear dynamic behavior of imperfect single-walled carbon nanotubes (SWCNTS) is investigated based on shell elasticity theory. According to the electronic microscope observations, most of the produced CNTS have imperfection and probably, there is not any ideal CNT without any defect. Therefore, in this study, the effect of imperfection on the nonlinear frequency and dynamic behavior is considered based on both classical and nonlocal shell elasticity theories and comparing it with the ideal CNT. The initial imperfection has been considered as a defect resulting from various kinds of defects. The imperfect SWCNT is modeled as an imperfect … Lire la suite

2023 — Meteorological risk assessment of Canadian transcontinental freight railway: Case study of Saskatchewan and OntarioRésumé
Railway transportation is the heart of the supply chain in Canada. The reason is that railway transportation is known as one of the most reliable and safest modes of transportation. However, due to its complexity, a wide range of risks are associated with this means of transportation. Considering Canada's climate, studying meteorological risks associated with the railway network can be useful for decision-makers in railway transportation, especially when preparing for cold seasons and implementing railway network development. In this study, a comprehensive spatial analysis using ArcMap has been applied to identify hotspots and vulnerable geographical areas in terms of meteorological … Lire la suite

2016 — Desire Lines: Treading Trails and Telling Tales of Lesbian MotheringRésumé
This study highlights the ways in which the marginalization of lesbian families in Canada and the United States is perpetuated by heterobias and exacerbated by the legislation that continues to exclude non-hetero families. As demonstrated in this study, however, this marginalization is actively being countered as lesbian mothers disrupt the hegemonic notions of motherhood and family by seeking to make their voices heard and stories known in the public sphere. The focus on lesbian parented families in this thesis is important and timely in its engagement of the social debate that continues to surround the queer community as a whole. … Lire la suite

2012 — Bringing It All Back Home: Apocalypse, Colonialism, and The Study of ReligionRésumé
In the study of religion, it will not take long before students come across the term “apocalypse” or “apocalypticism.” The place that such terms have made in the study of religion suggests that they refer to very tangible aspects of religious traditions. Moreover, the vast majority of scholarship, by way of comparison, reinforces the idea that the category apocalypse and apocalypticism represent a genre of writing native to Christianity and Judaism. Thus, studies of so-called apocalyptic texts often engage in comparisons of other “apocalyptic” materials contained within the Judeo-Christian tradition. These studies often base their comparisons on literary themes, and … Lire la suite

2023 — Effect of creatine monohydrate supplementation in aging adults with type II diabetesRésumé
Sarcopenia generally refers to the age-related reduction in muscle strength and physical performance, with greater decreases found in aging adults with type II diabetes (T2D). Supplementing with creatine, a nitrogen-containing compound formed from reactions involving the amino acids arginine, glycine and methionine, is an intervention which have been shown to increase muscle strength, endurance and physical performance in healthy aging adults. Further, creatine supplementation has been shown to influence glucose metabolism in individuals with T2D. However, the effects of creatine supplementation in aging adults with T2D in unknown. Therefore, the purpose of this study was to examine the effects of … Lire la suite

2014 — “Always in the process of Becoming”: Inquiring Narratively Into Providing Purposeful Support Towards Critical Social Justice EducationRésumé
Even as teacher education programs raise issues of social justice with pre-service teachers, the opportunities for them to practice their skills happen within the existing school structure— a structure that resists change. Many cooperating teachers who mentor pre-service teachers during their internship hold common-sense and taken-for-granted assumptions about what it means to be a “good” teacher that can interfere with the practice of critical social justice pedagogy. This narrative inquiry begins with an autobiographical exploration of my origins as a social justice educator and then examines the relationship between me, a cooperating teacher, and an intern as I strive to … Lire la suite

2014 — Passing Trauma Through Generations: Child Sexual Abuse as Perceived by CounsellorsRésumé
The purpose of this research was to understand how private counsellors, school counsellors and Indigenous holistic counsellors perceived the notion of Child Sexual Abuse (CSA) as an intergenerational phenomenon and to draw on their beliefs to gain understanding about the various causes, process, and effects of CSA. Child Sexual Abuse was examined here as an intergenerational occurrence with causation in families’ previous exposure to the phenomenon. This subject was investigated using qualitative research methods, namely Grounded Theory. The phenomenon of Child Sexual Abuse recurring in subsequent generations was explored through in depth interviews. Three self-identified Indigenous holistic counsellors (two male, … Lire la suite

2016 — Survival and Overland Transport of Fecal Coliform under Canadian Prairie ConditionsRésumé
In-field winter feeding of cattle is becoming a common practice in the Canadian Prairie. Cattle feeding in-field during winter provides economic advantages to agricultural producers over feeding the cattle in confined corrals by eliminating the extra work and cost associated with feed transport and manure management. Despite the economic advantages; wintering grounds for livestock operations can have profound impacts on water quality. Animal waste accumulated during winter can be transported to surface water with spring snowmelt. The potential impact on snowmelt runoff quality of winter in-field bale-grazing under the cold climate of Saskatchewan is being evaluated under the Saskatchewan component … Lire la suite

2014 — Single View Coplanar Photogrammetry and Uncertainty Analysis for Traffic Accident ReconstructionRésumé
Photogrammetry is defined as the science of measuring distances and objects by using photographs. Rapid advances in computer technology and digital photography in recent years have resulted in growing applications of digital photogrammetry. Although various aspects of photogrammetry have been investigated; the question of uncertainties in measurement, which is important for forensic applications, such as traffic accident reconstruction, has not been widely explored. This study attempted to develop an applicable comprehensive mathematical model to perform coplanar photogrammetry and provide a measure of uncertainty for its measurements. Photogrammetry requires information about the interior and exterior orientation of the camera. Process maximum … Lire la suite

2015 — Numerical Modeling of the Dam-Break on a Slope Channel by WC-MPS MethodRésumé
Numerical simulation methodologies have become a major approach for solving hydrodynamics problems over the past few decades. Due to their flexibility and adaptability, these methods can be employed in various subjects of engineering and science. These simulations are capable of providing the required knowledge to interpret the natural phenomena and as well can be an alternative means to study the theories and experiments. Numerical modeling of fluid flow can be categorized into two major approaches, mesh-based methods and mesh-free methods. Mesh-based methods used to be the dominant methods through the decades but their lack of success in the precise simulation … Lire la suite

2020 — Distinguishing Catheters from Their Echoes in Ultrasound ImagesRésumé
In brachytherapy of prostate cancer treatment, needles, called catheters, are inserted into the prostate of a patient. The accuracy of the catheters’ position is critical for the effectiveness of the treatment. Ultrasound images are commonly used to measure their positions. However, scattering of ultrasound signal in human tissue produces echoes of catheters that are sometimes, to the human eye, difficult to distinguish. The primary goal of this research is to investigate a novel approach for distinguishing ultrasound image regions corresponding to actual objects from the regions corresponding to their echoes. One of the challenges in ultrasound image analysis is the … Lire la suite

2015 — Verses at the Burning of the World: Modernism as a Fulfillment of Decadent IdealsRésumé
This thesis studies the transition between Decadent and Modernist poetry in England. The general critical perspectives of the evolution between the fin-de-siècle poetry of the 1890s and the high-Modernist verse of the 1920s were either of too great a separation, or too much a continuation. This study suggests that the Decadents were in fact precursors of the Modernists in their attempts to both stylistically and substantively challenge the dominant modes of poetry, its publication, and its relationship with the reading public in the face of the continued and exponential growth of industrialization, urbanization, commercialization, and other perceived consequences of modernity. … Lire la suite

2017 — Habitat selection and nesting ecology of translocated Greater Sage-grouseRésumé
Sagebrush ecosystems are one of the most imperiled ecosystems in North America. The cumulative effects of habitat loss, fragmentation and degradation of the sagebrush ecosystem threaten the persistence of the Greater Sage-grouse. Sage-grouse depend on healthy, intact areas of sagebrush habitat throughout the year. In Alberta, the sage-grouse population is estimated to be only 5% of what it was in 1968. During the spring of 2011 and 2012, 41 sage-grouse were fitted with GPS transmitters and translocated from stable populations in Montana to active lek sites in southeast Alberta. I conducted research to improve our understanding of translocation as a … Lire la suite

2016 — Self-Storying to (De)Construct Compulsory Heterosexuality: A Feminist Poststructural Autoethnography of a Self-Wedding RitualRésumé
Written from the perspective of a white-settler, obese, bisexual, middle class cisfemale graduate student in Canada, the wedding ritual and bride are explored as sites of ideal female/feminine formation of the subject. Compulsory heterosexuality is implicated. “Single” and “married,” like “woman,” are constituted in discourses. The author explores ways that she, as an unmarried and therefore “single” woman has been positioned as personally deficient as single-ness is produced as an illegitimate and undesirable position for female/feminine subjects to take up. This research uses an autoethnographic methodological frame augmented by feminist poststructural epistemology to open up, trouble, disrupt and interrupt the … Lire la suite

2014 — Media (Mis)Representations and the Muslim Body: A Lived CurriculumRésumé
My research explores the ways in which dominant media (re)presents, embodies, and constructs Omar Khadr in contradistinction to “real” Canadians, reflects upon the potential consequences of such representations for both “strangers” and “exalted subjects,” and contemplates as well ways to disrupt both these dominant and oppressive narratives. I also provide a framework for Khadr’s case as it relates to the biopolitical – that is the management of bodies by regimes of truth. To do this I analyze the larger context under which Omar Khadr’s case has unraveled by considering the ways that different techniques of management (re)produce bodies in complex … Lire la suite

2014 — Root Dynamics, Management Effects and Carbon Sequestration on Invaded and Native Semi-Arid GrasslandsRésumé
Root dynamics are a major component of terrestrial ecosystem processes but they have not been broadly studied, due to the difficulty of quantifying root production and mortality. The use of minirhizotrons facilitates belowground research, but sample intervals are controversial since long intervals miss roots that grow and die between the samples. Also, root responses to grassland management such as mowing are less well-known than shoot responses, even though as much as 83% of productivity in semiarid grasslands occurs belowground. Finally, the belowground dynamics of invasive species that change the vegetation of an area can be expected to alter the local … Lire la suite

2025 — Acceptance and commitment therapy for women experiencing infertility: A randomized controlled trialRésumé
Approximately one in six Canadian couples are infertile, defined as the inability to achieve pregnancy despite 12 or more months of active attempts to conceive. While the psychological burden is well-established in the literature, currently available and adapted psychological interventions have had minimal effects on infertility-related distress, anxiety, or depression. We examined the efficacy of Acceptance and Commitment Therapy (ACT) to reduce distress associated with infertility. In Study One, we created the ACT-based intervention in collaboration with a panel of women who had lived experience with infertility. We then conducted a pilot trial with 20 women and used their feedback … Lire la suite

2020 — Distress and Coping Among Infertile Women Attempting to Conceive NaturallyRésumé
Approximately one in five Canadian couples experience infertility, defined as being unable to achieve pregnancy despite 12 or more months of attempts to conceive. Experiencing infertility has been disproportionately associated with an array of psychological difficulties in women, however, there has been little research examining which coping strategies and behaviours may be helpful during these high-distress times of a woman’s cycle. Fifty-eight women were recruited for a study, via social media, examining the daily coping strategies and fertility monitoring methods (e.g., use of ovulation predictor tests), in relation to daily infertility distress among women with infertility. Over the course of … Lire la suite

2013 — The Effect of Breathing on Hip Roll Asymmetry in Competitive Front Crawl SwimmingRésumé
Front crawl swimming is a cyclic activity in which swimmers alternate arm and leg movements to create propulsive forces while the body rotates about its longitudinal axis. It has been suggested that breathing increases body rotation and potentially disrupts the symmetry of the stroke. This study quantified the effect of breathing on hip roll angle using a body-fixed (lower back) tri-axial accelerometer. Twenty (13 male, 7 female) provincial and national level swimmers performed four 100m front crawl trials at 70% of their best 100m time with 2 minutes recovery between trials. Four breathing conditions were tested: 1) unilateral preferred side, … Lire la suite

2015 — Leisure Spaces and leisure Constraints for Lesbian WomenRésumé
Researchers have argued that leisure and leisure spaces are gendered, differentiating men and women in their opportunities for and outcomes of leisure (e.g., Aitchison, 1999; Henderson & Shaw, 2006). Gender expectations generate leisure constraints especially for women (Shaw et al., 1991). Furthermore, within the female group, lesbians face additional constraints because of the intersection of sexism with homophobia (Pritchard et al., 2002; Taylor, 2007). In 2011, I conducted an online pilot study with a sample of 813 lesbians which suggested that for most participants, self-consciousness and fear of harassment prevented them from fully enjoying their leisure in public spaces. This … Lire la suite

2017 — A Meta-Analysis of Neuropsychological Outcomes of the Frontal Lobe Following ChemotherapyRésumé
Cancer affects a large number of people. According to the Canadian Cancer Society (2016), the prevalence of cancer is 2.4% or approximately 1 out of every 42 Canadians. Chemotherapy is a common component of cancer treatment protocols; however, there are varying reports of cognitive dysfunction following administration. A proposed mechanism of dysfunction is that chemotherapy expedites the presentation of outcomes associated with the normal aging process, particularly frontal lobe functions (e.g., verbal fluency, planning, and inhibition). As frontal lobe functions have been shown to be more vulnerable to aging than other cognitive processes, these functions were the focus of the … Lire la suite
