Indigenization Of Postsecondary Education Applied Learning Curriculum Development, Gabriel Y. Chung

The Dissertation in Practice at Western University

The Truth and Reconciliation Commission of Canada’s (2015) Calls to Action have awoken Canadian society to the reconciliation. Although there is a growing body of knowledge on the individual topics of Indigenous education, knowledge, and leadership, there is relatively little research bringing together these topics in curriculum development practices in a postsecondary education skilled learning context. My problem of practice (PoP) is one that strives to address a low enrolment of Indigenous adult learners and lower positive outcomes from skilled training programs. Situating this problem from my perspectives as a Canadian-born visible minority Settler on Turtle Island and postsecondary education …

The Roles Of Fabp3 In Endothelial Dysfunction And The Transcriptomic Insights Into Cardiovascular Disease, Chi Hien Nguyen

Electronic Thesis and Dissertation Repository

Heart-type fatty acid binding protein (FABP3) is an effective biomarker for cardiac injuries. However, it has also been tested as a biomarker in patients with peripheral artery diseases; these conditions are complications of atherosclerosis, which is driven by endothelial dysfunction. As FABP3 release is not exclusive to the heart but appears to characterize cardiovascular events, whether FABP3 influences endothelial function is not known. Additionally, the transcriptomic profiles of endothelial cells during cardiovascular stresses remain under-investigated. This thesis investigates the multifaceted role of FABP3 and the transcriptomic alterations in endothelial cells under different cardiovascular stressors, offering novel insights into endothelial dysfunction …

Machine Learning Classifiers For Chronic Obstructive Pulmonary Disease Assessment Using Lung Ct Data., Halimah Alsurayhi

Electronic Thesis and Dissertation Repository

Chronic Obstructive Pulmonary Disease (COPD) is a condition characterized by persistent inflammation and airflow blockages in the lungs, contributing to a significant number of deaths globally each year. To guide tailored treatment strategies and mitigate future risks, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) employs a multifaceted assessment system of COPD severity, considering patient's lung function, symptoms, and exacerbation history. COPD staging systems, such as the high-resolution eight-stage COPD system and the GOLD 2023 three staging systems, have been later developed based on these factors. Lung Computed Tomography (CT) is becoming increasingly crucial in investigating COPD as it …

Creating Legitimacy: The Dyarchy In Spartan Social Memory, Stephanie J. Dennie

Electronic Thesis and Dissertation Repository

Scholars of the constitutional development of Archaic Sparta and its dyarchy (or dual kingship) have long considered Tyrtaios’ Eunomia contemporary evidence for the mysterious lawgiver Lykourgos, whose alleged reforms have largely been reconstructed from late-Classical and Roman sources. According to orthodox narratives of Lykourgos, seventh-century Sparta enjoyed internal stability and good governance, but Tyrtaios’ seventh-century poem strongly suggests the continued existence of civil strife. Drawing on social memory studies and archaeological survey data, this dissertation questions the Lykourgan grand narrative and explores the capacity of Tyrtaios’ Eunomia to help us recontextualize Sparta’s socio-political development in the seventh century BCE.

The Black-To-White Hole Transition, Farshid Soltani

Electronic Thesis and Dissertation Repository

Classically, an isolated black hole is a stable gravitational object. If however semiclassical effects are taken into account, an isolated black hole can be shown to slowly radiate its mass away in a process called evaporation. At the end of the evaporation process, when the size of the horizon becomes Planckian, the quantum nature of the gravitational field can no longer be neglected and the dynamics of the horizon is governed by quantum gravity. The main objective of this thesis is the systematic investigation of a tentative scenario for the “end of the life” of a black hole: the black-to-white …

Determining The Effects Of Mistranslating Transfer Rna Variants On Drosophila Melanogaster, Joshua R. Isaacson

Electronic Thesis and Dissertation Repository

Transfer RNAs (tRNAs) play a central role in translation as adaptor molecules between mRNA and protein. Variant tRNAs can cause the misincorporation of an amino acid into a growing polypeptide. Mistranslating tRNA variants are surprisingly common in humans but the effects of mistranslating tRNA variants on eukaryotic biology are poorly understood. My thesis aimed to create a model of tRNA-induced mistranslation using the fruit fly Drosophila melanogaster and characterize the effects of mistranslating tRNA variants on eukaryotic biology.

I first integrated a gene encoding a serine tRNA variant that induced proline-to-serine (P>S) mistranslation into the fly genome. Proteins isolated …

“We Make Things Today For Tomorrow”: Artists’ Publishing For The Future, Ruth Skinner

Electronic Thesis and Dissertation Repository

This dissertation is an exploration of artists’ book, artists’ publishing, distribution, and archival practices from a number of vantages in order to explore the activist possibilities of contemporary arts publishing. The concept of urgent artifacts, developed by publisher Paul Soulellis, reverberates throughout this research. The liveliness of this term is enhanced through applying additional modes of experience: clairvoyance, forensics, thinness, as well as their tricky interplay. In exploring what artists’ publishing might require for the present and the immediate future, this research-creation project considers the possibilities that clairvoyance—in particular, the figure of the medium—and archival intuition might offer. Borrowing from …

Physical And Geometrical Modulation Of Human Fibroblast Behaviour, Sarah M. Brooks

Electronic Thesis and Dissertation Repository

This thesis investigates the impact of mechanical stimuli, specifically substratum topography and elastic modulus, on dermal and gingival fibroblast behaviour associated with scarring and regeneration. Scar formation presents a significant issue for implanted biomaterials often leading to device failure. Even though scar formation is a normal end point to adult human dermal wound healing, gingival wounds are capable of tissue regeneration or scarless wound healing. Understanding how these cells respond to environmental cues, including substratum topography and elastic modulus, is central to the development of novel biomaterials for stimulation of tissue regeneration. It was hypothesized that topographic features, with submicron …

Anxiety In Children And Adolescents With Autism Spectrum Disorder: Behavioural Phenotypes And Environmental Factors, Caitlin E. Leachman Miss

Electronic Thesis and Dissertation Repository

Anxiety is the most prevalent comorbidity among children and adolescents with autism spectrum disorder (ASD). The phenotypical presentation of anxiety among children and adolescents with ASD is lacking within the literature. This study sought to differentiate behavioral phenotypes associated with anxiety in children with ASD from anxiety in typically-developing children. Participants completed a series of child and parent reports measuring anxiety, depressive symptoms, ASD symptom severity, emotional problems, parental stress, and socioeconomic factors. Three distinct anxiety profiles, including moderate, high, and low, were identified. Results demonstrated that depression is the strongest predictor of high anxiety among children and adolescents with …

Bioactive And Electrically Conductive Nanocomposite Bone Biomaterials, Rebeca A. Arambula-Maldonado

Electronic Thesis and Dissertation Repository

Electrically conductive carbon-based materials are emerging as potential biomaterials for bone tissue engineering. Their incorporation into organic-inorganic nanocomposites mimics the structural composition and electrically conductive nature of bone.

The aim of this research was to design bone biomaterials from gelatin-based polymers, tertiary bioactive glasses (BG) via a sol-gel method, and multiwall carbon nanotubes (MWCNT). The incorporation of calcium into organic-inorganic nanocomposites plays an essential role in the development of bioactive bone biomaterials. Calcium chloride and calcium ethoxide were investigated as calcium sources in gelatin-BG-MWCNT nanocomposites. The resulting surface elemental distribution was homogeneous, but the swelling, degradation and porosity properties of …

Performing Masculinity: Calgary Men In The Great War, Andrew J. Hawkes

Electronic Thesis and Dissertation Repository

This thesis explores the masculinity of soldiers from Calgary during the Great War using a theoretical framework of hegemonic masculinity. The first chapter establishes a normative masculine standard in Calgary using local newspaper coverage of battalion departure parades. These events were rituals that celebrated militarized masculinity and reinforced the hegemonic ideal that existed across the British Empire in the early 20^th century. The second chapter assesses how masculinity was performed in letters during the war. Although men strove to embody the masculine ideal, their letters were not uniform endorsements of martial masculinity. The third chapter analyzes how hegemonic masculinity …

What Are You Ruminating About? The Development And Validation Of A Content-Dependent Measure Of Rumination, Christopher M. Kowalski

Electronic Thesis and Dissertation Repository

Rumination is a past-focused distress response characterized by repetitive and passive fixation on symptoms, possible causes, and/or consequences of distress (Nolen-Hoeksema, 1991). To date, previous measures of rumination have focused on general levels of rumination without considering the content of ruminative thought. This dissertation describes the development of a new rumination measure, the Rumination Domains Questionnaire (RDQ), which considers the content of ruminative thought. Furthermore, the present dissertation describes group differences found in the content of ruminative thought that have been difficult and/or unfeasible to capture in research prior to the introduction of the RDQ. In the introduction, a case …

Chest Computed Tomography And Magnetic Resonance Imaging Texture Measurements Of Chronic Obstructive Pulmonary Disease, Maksym Sharma

Electronic Thesis and Dissertation Repository

Pulmonary imaging using computed tomography (CT) and magnetic resonance imaging (MRI) provide a method to measure airway and parenchymal pathologic information that cannot be provided using spirometry. Currently, it remains difficult to predict which chronic obstructive pulmonary disease (COPD) patients will worsen using spirometry, which although safe and inexpensive, does not provide small airway information where COPD is believed to initiate. Quantitative CT and MRI measurements provide regional structure and function information but are not included in mortality risk assessments, prognosis, or COPD staging. Therefore, my overarching hypothesis is that CT and MRI ventilation texture measurements combined with machine learning …

Resolving The Longitudinal Triglyceride Phenotype Of Heterozygous Lpl And Apo A-V Deficiency, Shehan D. Perera

Electronic Thesis and Dissertation Repository

Hypertriglyceridemia (HTG) is a risk factor for cardiovascular disease. However, only the triglyceride (TG) phenotype produced by biallelic loss-of-function (LOF) variants in the canonical TG metabolism genes is well understood. The TG phenotype produced by monoallelic LOF variants is poorly understood. We aimed to evaluate the TG phenotype associated with monoallelic LOF variants in the canonical TG metabolism genes.

Next-generation sequencing panel was employed to identify patients heterozygous for LOF variants in two of the canonical TG metabolism genes LPL and APOA5, followed by chart review to determine baseline and longitudinal TG phenotype in these patients.

My findings suggest …

Extinction Anxiety As Zeitgeist: An Examination Of The Cultural Anxiety Surrounding Extinction Threats, Spencer J. Kett

Electronic Thesis and Dissertation Repository

This thesis examines extinction anxiety as a zeitgeist that manifests through nuclear war anxiety and climate change anxiety. I define extinction anxiety as the cultural mood of anxiousness surrounding extinction threats in the past, present, and future. I use Monika Krause’s sociological conception of zeitgeist to understand these anxieties as a cultural mood. I demonstrate using Jean-Paul Sartre’s conceptualization of materially derived subjectivity, how these moods of anxiousness are internalized through material conditions. I build my concept of extinction anxiety by comparing and contrasting the mood of anxiousness surrounding nuclear war during the Cold War and the current mood of …

Structure And Function Of Long-Covid Evaluated Using Pulmonary Imaging, Harkiran Kaur Kooner

Electronic Thesis and Dissertation Repository

The COVID-19 pandemic has resulted in millions of global respiratory infections, ranging in severity from asymptomatic to fatal. One of the many consequences of the pandemic is the emergence of long-COVID, which is an umbrella term used to describe the long-term sequelae and poor quality-of-life following recovery from acute COVID-19 infection. However, the pathophysiology and mechanisms responsible for the heterogenous manifestation of long-COVID remain poorly understood. Hyperpolarized ¹²⁹Xe magnetic resonance imaging (MRI) provides a non-invasive and radiation-free method to regionally visualize and quantify inhaled gas distribution and ventilation in vivo. A strong foundation for the use of pulmonary …

Listening To "Silence": Alternative Modes Of Communication In Korean And Korean American Women's Literature, Judy Joo-Ae Bae

Electronic Thesis and Dissertation Repository

South Korean feminist activity may be relatively unknown to many Western readers; however, a distinct form of feminist activism can be seen when considering alternative modes of communication that are not less than, simply different from “speech” or “voice” as forms of agency celebrated in the West. Alternative modes of communications such as silence, song, touch, and performance also speak important messages which can be heard when understood through local knowledges. In the three cases of South Korean and Korean American women’s fictions used in this dissertation, I unpack these alternative modes of communications used by the female protagonists through …
