2020 — Sustaining Clinical Competency in Wide Open Spaces: A Communities of Practice Case Study of Rural School PsychologistsAbstract
The practice of a rural school psychologist is challenging and can be fraught with aspects of isolation, role confusion, and burn out (Hargrove, 1986). In many rural communities, the only qualified mental health professional may be a school psychologist. Thus, rural school psychologists require particular and generalist skill sets to meet the diverse needs of their community. This reality is in contrast to dominant discourses within the broader field of psychology, which promote limited scopes of practice within defined areas of clinical competency. A collective case study of rural school psychologists from across Saskatchewan using a Communities of Practice (Wenger, … Read more

2011 — An Examination of Leaf Morphogenesis In The Moss, Physcomitrella PatensAbstract
Physcomitrella patens is a simple model plant belonging to the bryophytes, which diverged from the tracheophytes approximately 500 million years ago. The leaves of the moss are similar in form to vascular plant leaves although leaves evolved independently in the bryophyte and tracheophyte lineages. Close examination of the morphology of Physcomitrella leaves and investigation of the morphogenetic processes that result in the leaf form and of the hormonal and genetic regulation of those processes will elucidate the evolutionary trajectory of moss leaves. Photomicroscopy and measurement of moss leaves were performed to provide detailed descriptions of leaves in strains of Physcomitrella … Read more

2014 — The Prevalence of Bacteria-Sediment Associations and Their Effect on Sediment Settling Velocities in Aquatic Environments of Agricultural Saskatchewan and Alpine British ColumbiaAbstract
Bacteria-sediment associations (BSA) are the natural interactions between bacteria and sediment particles that influence both bacterial survival rates and properties of sediment particles. A newly developed method for quantifying BSA was applied to an agricultural watershed in southeastern Saskatchewan and an alpine watershed in the southern Coast Mountains of British Columbia. Both watersheds exhibited spatial and temporal trends of BSA. Impacts corresponding to land use and anthropogenic activity are also present. Development of a novel method for determining BSA allowed for samples taken from remote areas to be assessed. Membranes with 8 μm pore diameter separated planktonic organisms from sediment-associated … Read more

2012 — Sinister Spaces: Liminality and the Southern Ontario Gothic in Margaret Atwood's FictionAbstract
Margaret Atwood’s works are undoubtedly influenced by her academic training in Gothic and Victorian fiction. However, she also incorporates the influences of Southern Ontario – her backyard – and its regional subgenre of Southern Ontario Gothic. While traditional Gothic certainly incorporates binaries, Michael Hurley, the scholar at the forefront of the discussion of this unique subgenre, suggests that characters within this subgenre are entrapped in the liminal spaces created not simply by the meeting of seeming opposites, but at the points where their boundaries are blurred. Atwood’s fiction represents these liminal spaces; however, she provides options for a hopeful ending … Read more

2017 — Deep Exclusive Pseudoscalar Meson Production at Jefferson Lab Hall CAbstract
Measurements of exclusive meson production are a useful tool in the study of hadronic structure. In particular, one can discern the relevant degrees of freedom at different distance scales through these studies. In the transition region between low momentum transfer (where a description of hadronic degrees of freedom in terms of effective hadronic Lagrangians is valid) and high momentum transfer (where the degrees of freedom are quarks and gluons), the predictive power of Quantum Chromodynamics (QCD), the theory of the strong interaction, is limited due to the absence of a complete solution. Thus, one has to rely upon experimental data … Read more

2022 — RIM-Decay: A deep learning method for clinical predictionAbstract
The advancement in Electronic Health Records (EHR) and clinical prediction has led to research on effectively predicting patients’ health conditions and events to assist medical professionals. A Delay of appropriate medical attention would result in the loss of life. Prediction of early mortality, length of stay, and acute respiratory failure based on vital measurements such as temperatures, blood pressure, heart rate, sugar level, etc., would assist in saving life and cost. EHR records are sparse and noisy; hence patients have varied vital measurements and length of stay. Due to the lack of a unified digital health record-keeping system, high sparsity, … Read more

2012 — Anti-Oppressive Education Through English Language Arts: A Recollecting JourneyAbstract
This study contributes to the field of anti-oppressive education, with an intentional focus on English Language Arts (ELA). The research addressed perpetuating oppression within education, specifically in ELA. In addressing this problem, I used narrative and Indigenous methodologies as my theoretical frameworks. I feel that Indigenous methodology lies in the realm of story for the betterment of the collective group and future. Identity is (re)produced and influenced by historical background, social construction, racial identity, and religious identity which shape power relations and social positioning. Through students developing critical literacy skills, applying them to curricular material, and transferring their ways of … Read more

2012 — An Analysis of Young Offender Case Management Factor Items in SaskatchewanAbstract
The Level of Service Inventory Saskatchewan Youth Ed. (LSI SK Youth Ed.) is a risk assessment tool designed to be used with young offenders to determine the level of service necessary to reduce offending and inform case planning. There are eight vulnerable areas known to be criminogenic identified in the assessment that inform key areas for intervention and treatment in each offender’s case plan. The assessment also appends three sections of supplementary information (case management factor items) that might assist or affect case planning in the eight areas. The three sections consist of: 1) attributes or personal characteristics of the … Read more

2020 — A Wi-Fi Active Antenna to Model 5G Beam ManagementAbstract
In this thesis, an active antenna model is created using a Wi-Fi omnidirectional antenna to fashion a 5G-like set up and to test its beam management capability. This active antenna is a dynamic antenna that operates based on the real-time user location and throughput data rate. This mechanical model is based on the concepts of beamforming, beam steering, control theory and user tracking. 5G communication will be utilizing the mmWave spectrum. Therefore, beam directivity, because of mmWave path loss, is of paramount importance for the success of 5G. This model can be used to re-align the antenna towards the user … Read more

2023 — A flight for survival and safety: A feminist phenomenological study of women's experiences of intimate partner violence and homelessnessAbstract
his study explores the experiences of four Saskatchewan women as they describe their experiences attempting to maintain housing after their abusive relationship had ended. Using phenomenological methodology provides rich descriptions of what it is like for survivors to navigate housing support services in Saskatchewan. The women’s experiences were gathered through in-person semi-structured interviews, allowing for both structure and flexibility. The study's findings highlight how additional barriers such as stigma, economic abuse, and financial struggles can create significant barriers for some women. These findings add to the growing scholarship in Saskatchewan exploring the link between intimate partner violence (IPV) and women's … Read more

2016 — Learning Erasing Pattern Languages from Minimal InformationAbstract
A pattern is a concatenation of variable symbols and constant symbols. The language of a pattern is the set of strings generated by replacing the variables of the pattern with all possible strings. Patterns and pattern languages, introduced by Angluin, have attracted much attention in the past 35 years. In this thesis, we study learning the class of erasing pattern languages within three models of learning: classic teaching, recursive teaching, and query learning with shortest additional information. In the rst model, a teacher chooses helpful examples to help the learner in the process of learning. We measure the complexity of … Read more

2017 — REVO: A flexible, volumetric approach to mesh constructionAbstract
Meshes are used in a variety of applications to specify the three dimensional (3D) shapes of objects in simulated scenes. For example, a mesh can be used as an animal in an animation movie, a soldier in a video game, or a bulldozer in a simulation application. A straightforward way of creating a mesh is to modify an existing mesh. Although several mesh modi cation algorithms exist, there is a need for an algorithm that constructs a mesh from any combination of existing meshes and simple geometric shapes (called primitives) according to a list of user commands. When visualized, the … Read more

2016 — Equivariant LS-Category and Equivariant Topological ComplexityAbstract
In this thesis we consider topological spaces endowed with an action of a topological group, and we develop a new concept to study these spaces. This concept is called orbit class and is often a good replacement for the well-known concept or- bit type. Using the concept of orbit class, we de ne a partial ordering on the set of all orbit classes. This partial order not only gives a partition on the topological space based on the orbits, but it also gives a discrete combinatorial translation of the topological space. We also use the properties of the orbit class … Read more

2023 — Optimizing Internet-Delivered Cognitive Behavioural Therapy for public safety personnel: Qualitative insights from clients and stakeholders to guide program improvementsAbstract
Public Safety Personnel (PSP) (e.g., EMS/paramedics, police officers) experience high rates of clinically significant symptoms of mental health disorders. The high rates have been explained by the extraordinary occupational stressors that PSP experience. There is a need for accessible treatment options to overcome common barriers to care in PSP populations. Internet-delivered cognitive behavioural therapy (ICBT) has the potential to provide effective treatment while overcoming barriers to care. PSPNET is a clinical research unit that has adapted an ICBT program to meet the needs of PSP. The current dissertation is designed to explore the extent to which PSPNET has been optimized … Read more

2012 — Developing New Tools for Detecting Germline Mutation Induction in MiceAbstract
Identifying factors that influence germline mutation rate in animals is an important toxicological consideration. However, research in this area is limited by the lack of efficient and precise tools for characterizing germ cell mutagens in humans and model species such as mice. Thus, the purpose of my research was to develop new tools for quantifying germline mutation induction in mice. My first objective was to identify polymorphic microsatellites as a new tool for detecting changes in germline mutation frequency. Enrichment and DNA sequencing of microsatellites in closely related inbred mouse lines was used to identify polymorphic loci. The loci were … Read more

2015 — Environmental, Social and Economic Impacts of the Changing Wastewater Regulatory Landscape and Engineering Design Requirements in CanadaAbstract
In 2009, the Federal Government established new regulations for municipal wastewater systems and encouraged the provinces and territories to take part and formally commit to meeting the new limits. Saskatchewan, along with other provinces and territories, agreed to incorporate the new standards into their provincial legislation by signing the Canada-Wide Strategy for the Management of Municipal Wastewater Effluent (the Strategy). This paper will review the current provincial wastewater effluent regulations in Saskatchewan and the changes that are being made to meet the requirements set out in the Strategy. The most significant changes are to reduce the concentration of nutrients that … Read more

2019 — Measurement of the Beam Asymmetry for the ETA and ETA Prime Mesons with the Gluex ExperimentAbstract
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. An … Read more

2020 — Dirt PharmacyAbstract
My creative thesis, Dirt Pharmacy, is a historical fiction novella about a murder in seventeenth-century London. As a Renaissance-era crime thriller, my work is influenced by a number of writers who work in the genre and period, such as Patricia Finney, C.J. Sansom, and Rory Clements. Where my work differs from theirs is that I examine early modern crime the other way around; their protagonists are proto-detectives, while Dirt Pharmacy is written from the point of view of the women committing the murder. My aim is to shine a light on two parts of history that typically go unseen, and … Read more

2015 — Assessing Value in Upstream Health Interventions: A Case Study of the Dr. Paul Schwann Centre Cardiac Rehabilitation ProgramAbstract
In the past several decades, a major ideological shift has occurred regarding the relative importance of broad socioeconomic factors as determinants of health over access to conventional health services. During this time, public health experts have continually re-emphasized the need to focus attention further “upstream” of disease, in order to prevent populations from developing poor health. While provincial health systems currently integrate some population and public health programming within the basket of services they offer, upstream health interventions represent only a very small proportion. While many factors can explain this pattern, one explanation is key; upstream health interventions must compete … Read more

2022 — A usability study of Internet-delivered cognitive behaviour therapy and resource tailored to agricultural producersAbstract
Agriculture producers experience high rates of mental health challenges and are less likely to seek or to receive help for mental health concerns than the general population. Internet-delivered cognitive behaviour therapy (ICBT) is demonstrated to be effective for reducing symptoms of anxiety and depression and overcomes many barriers to receiving mental health care. Research evaluating the usability and effectiveness of online psychological interventions for the agriculture population specifically is scarce. The goal of this study was to assess the usability of ICBT for Saskatchewan agricultural residents and its impact on symptoms of anxiety/depression, perceived stress, and resiliency. The objectives of … Read more

2014 — Psychology’s Philosophical Foundations: In Search of a Unifying TheoryAbstract
I am concerned with fragmentation in psychology among its theories and research projects. There is in particular a clear debate between those who propose a scientific conception of psychology versus those who propose a broader, more expansive conception of its subject matter and method. The proponents of these two opposed conceptions of psychology agree that psychology is in need of an epistemology. I argue, instead, that psychology first needs to identify its metaphysics. That metaphysics will be its subject matter, as well as what is required for the study of any subject. I propose that Psychology’s metaphysics is the person, … Read more

2020 — In Between: A Case Study of Frontline Workers and Response to SuicideAbstract
Suicide is a tragic, multi-faceted and complex global issue which disproportionately impacts marginalized communities. This case study examines the experience, impact and recommendations from frontline workers who endured a prolonged youth suicide crisis within a marginalized, northern Indigenous community. This thesis examines how frontline workers experienced a youth suicide crisis, with the hope that the findings might influence policy with respect to how provincial and federal governments engage with communities that struggle with the same challenges. A thematic analysis of eight interviews with professionals who worked in a variety of frontline services that were impacted during a youth suicide crisis … Read more

2021 — Analysis of Strobilurin Fungicides, Neonicotinoid Insecticides and Degradation Products in Atmospheric ParticlesAbstract
In this study, a liquid chromatography-tandem mass spectrometry method has been developed for the simultaneous detection of concentration of 8 neonicotinoid insecticides with 5 degradation products of neonicotinoid insecticides and 7 strobilurin fungicides in the particle phase of atmospheric samples. Detection limits ranged from 0.5 to 3 ng/mL and the recovery percent ranged between 83.5% to 108.3% with relative standard deviation <13% for all analytes. The sampling site was located in Omak, WA within the Okanogan County agricultural region where vineyards and apple orchards are the dominant crops. Matrix effect was determined to evaluate the performance of the developed sample clean-up procedure to remove the matrix. The determined matrix effect revealed that the highest exhibited matrix effects were for metabolites of neonicotinoids, while strobilurin fungicides showed soft to moderate matrix effects in >75% of samples. Neonicotinoids that were detected included imidacloprid, clothianidin, acetamiprid, and thiamethoxam. The highest detection frequency in 2016 was shown for imidacloprid (47%), while in 2018 acetamiprid had the highest detection frequency (67%). This is the first time …</13%> Read more

2013 — Alternative Land Tenure: A Path Towards Food Sovereignty in Saskatchewan?Abstract
In the past few years, a global food crisis has fuelled corporate investment and speculation in land and the attendant dispossession of smallholders and ecological damage, while doing little to alleviate hunger or secure livings for rural dwellers. This phenomenon is most evident in the Global South, but it is happening in Canada too. The dominant industrial agricultural model in Saskatchewan, with roots in the foundation of colonial capitalist agriculture and private ownership of land on the prairies, has resulted in a decades-long “farm crisis” as smaller farmers are forced off the land and agribusinesses consolidate and dominate production. A … Read more

2024 — A commercial pathway for evaluating the performance of a novel amine solvent blend in a mini-pilot plant for carbon captureAbstract
This study investigates the performance of a novel solvent bi-blend, 4M (2:2) AMP:1-(2HE) PRLD, for CO2 capture through absorption and desorption, providing a potential alternative to the conventional 5M Monoethanolamine (MEA). The pathway utilized to assess the performance of the amine bi-blend for commercial application involved conducting carbon capture experiments in a laboratory bench-scale mini-pilot plant. This approach aimed to validate the solvent's performance under conditions that mimic a full-scale commercial industrial CO2 capture plant. The research also addresses the urgent need for more efficient and cost-effective carbon capture solutions to combat increasing greenhouse gas emissions and global warming. Experiments … Read more

2012 — Maintaining the "Achievement Gap": How the Discourses of Wide-Scale Assessments Marginalize Students and Preserve the Educational Status QuoAbstract
Using Critical Discourse Analysis and Foucaultian Discourse Analysis, this study applies postcolonial theory to an examination of the discourses of wide-scale reading and writing assessments in Saskatchewan. The study provides answers to three questions examining how the discourses of wide scale assessments in reading and writing construct disadvantages for First Nations and Métis students and simultaneously construct advantages for white settler students. The research data includes the publicly available Assessment for Learning instruments, handbooks, pre-assessment materials, scoring guides and reporting documents for 2005 through 2010, a total of 177 documents. The analysis indicates that there are at least four distinct … Read more
