Type d'Item : Item , L'art du drag comme expérience de guérison chez les personnes trans* et non binaires : une étude participative en sciences infirmières(Université d'Ottawa / University of Ottawa, 2026-09-21) Turcotte, Mathieu; Perron, Amélie; Goumoëns, Véronique deLes écrits scientifiques documentent que les personnes vivant une trajectoire transidentitaire ou non binaire sont exposées, dans les systèmes de santé, à une triangulation de mécanismes de contrôle fondée sur l'ignorance, la pathologisation et la peur, reconduite par des paradigmes disciplinaires cishétéronormatifs. Ce projet doctoral repose sur le besoin de comprendre en quoi l'art du drag peut permettre des expériences de guérison pour ces populations, dont les vécus demeurent structurellement sous-représentés dans les sciences infirmières. Le cadre théorique s'appuie sur la théorie queer et l'art performatif, articulant performativité du genre, parrhèsia, souci de soi, liminalité et guérison radicale. L'ethnodrag, approche méthodologique originale développée dans le cadre de cette recherche, intègre l'ethnographie critique, l'enquête incarnée, l'ethnodrame et la recherche-action participative, déployés en trois phases avec six artistes drag trans* et non binaires à titre de cochercheureuses, soit des entretiens et groupes focus, des ateliers de cocréation et une performance artistique à Lausanne en juin 2025 (n = 131 questionnaires du public). Les résultats se regroupent sous trois thèmes, soit 1) le souci et récit de soi, désignant un travail incarné par lequel les artistes construisent un rapport à soi traversé d'opacité constitutive, 2) la parrhèsia corporelle, soit une prise de parole courageuse réalisée par et à travers le corps en performance et 3) la synergie artiste-public, espace liminal de coconstruction dans lequel la guérison prend une dimension collective et politique. Ces trois dynamiques, conceptualisées sous le terme de Healing Speech, révèlent que la guérison ne constitue pas un retour à une norme, mais une pratique transgressive et incarnée de transformation de la personne. Ces résultats ont des implications pour la formation, la pratique clinique et la recherche en sciences infirmières auprès des populations historiquement marginalisées des systèmes de santé.Type d'Item : Item , A Pilot Study Evaluating the Perceived Effectiveness of a Virtual Simulation Module to Enhance Nursing Care and Diabetes Self-Management Education Among Persons Experiencing Homelessness(Université d'Ottawa / University of Ottawa, 2026-09-21) Lock, Mercedes; Tyerman, JaneBackground: Type 2 diabetes disproportionately affects persons experiencing homelessness due to barriers related to the social determinants of health. Nursing students often report feeling unprepared to address the complex contextual factors in clinical practice. -- Purpose: This pilot study examined the perceived effectiveness of a virtual simulation module designed to support undergraduate nursing students' learning about diabetes self-management in the context of homelessness. -- Methods: A two-phase sequential multi-methods descriptive design informed by Kolb's Experiential Learning Theory was used. Phase I included quantitative data collected using the Simulation Effectiveness Tool-Modified (SET-M). Phase II involved semi-structured interviews analyzed using thematic analysis. Participants included fourth-year Bachelor of Science in Nursing students (n = 11) enrolled in Nursing Practice and Complex Care Situations (NSG4430) at the University of Ottawa. -- Results: Quantitative findings in Phase I indicated high perceived effectiveness across SET-M subscales, particularly in clinical reasoning, communication, and discharge planning. Qualitative analysis in Phase II identified three themes: (1) Preparedness and contextual understanding, (2) Building confidence and clinical reasoning in a safe learning environment, and (3) Integrating knowledge through reflection. -- Conclusion: Virtual simulation may be an approach for advancing equity-orientated diabetes self-management and the social determinants of health into undergraduate nursing education. The intervention highlights the potential to enhance student learning and clinical reasoning in caring for vulnerable populations. Further research with larger and multi-site samples is recommended to evaluate its broader impact.Type d'Item : Item , Variation, Development, and Evolution of Head Structures in Ants(Université d'Ottawa / University of Ottawa, 2026-09-21) Vong, Erica; Rajakumar, RajendhranMorphological diversification arises through the interaction of environmental, evolutionary, and developmental processes that determine a trait's size, shape, and scaling relationship. In ants, these processes are further structured by caste systems where discrete phenotypes emerge. This thesis investigates how allometry, developmental plasticity, and patterns of integration and modularity contribute to the diversification of caste-specific head morphology (antenna and mandibles) in the hyperdiverse ant genus Pheidole. Chapter 2 identifies a previously undescribed morphological pattern in antennal scape length, where scape-to-body scaling is decoupled between worker and soldier castes but scales within each caste. Comparative analysis across the genus reveals the pattern is widespread, while comparative analysis across ants reveals this pattern's possible evolutionary origin. Experimental manipulations of hormonal, pheromonal, and inter-organ signalling pathways demonstrate their role in regulating trait-to-body and their ability to access unrealized developmental potentials to generate novel phenotypes, including nanoworkers and nanosoldiers. Chapter 3 examines scaling within the antenna, demonstrating that individual segments follow varying scaling relationships with body size. Where intermediate segments vary with overall body size, and proximal and distal segments deviate, indicating modular organization of the antenna. Experimental manipulations of hormonal, pheromonal, and inter-organ signalling pathways demonstrate their role in regulating the modular components of the antenna. Chapter 4 investigates mandible morphology in terms of size and shape. Workers and soldiers have distinct size and shape, where conserved developmental timing suggests differences in patterning pathways, and inter-organ signalling of a soldier-specific organ is important soldier size but not shape. This indicates that size and shape for mandibles are governing by partially independent developmental pathways. Together, this thesis shows that morphological evolution in Pheidole is governed not only by changes in trait size and shape, but also the altering of scaling relationships through caste evolution and developmental regulation, highlighting how allometry, modularity, and integration interact to generate morphological diversity.Type d'Item : Item , Reframing Home: Diasporic Hybridity, Spatial Aesthetics, and Affective Spectatorship in Arab-Canadian Cinema(Université d'Ottawa / University of Ottawa, 2026-09-21) Zhao, Zixuan; Talmisānī, MayyThis dissertation argues that Arab-Canadian cinema constitutes a politically significant cultural formation that actively shapes, rather than merely reflects, the diasporic identities of Arab and Muslim communities in Canada. Analysing fictional and documentary works produced between the early 1990s and the mid-2020s - such as Ruba Nadda's Sabah (2005) and Cairo Time (2009), Bachir Bensaddek's Montréal la blanche (2016), Pierre Sidaoui's A Scent of Mint (2002), Nisreen Baker's Things Arab Men Say (2016), and Arab Women Say What?! (2023) among others - the study contends that these films generate representational spaces in which identity is negotiated and reimagined against Orientalist misrepresentation, post-9/11 racialisation, and the structural asymmetries concealed within Canadian multicultural discourse. Three analytical frameworks structure the inquiry. The first draws on Bhabha's theory of hybridity and the third space, Brah's diaspora cartographies, and Anzaldúa's borderlands concept to examine diasporic identity as an embodied, processual negotiation expressed through spatial configurations, sensory aesthetics, and elemental metaphor. The second applies Crenshaw's intersectionality paradigm and critical race theory to analyse the interlocking operations of race, gender, religion, and class in the films' representations of Arab and Muslim femininity, masculine vulnerability, and the differential politics of mobility in Canadian urban space. The third builds on Hall's encoding/decoding model to investigate how filmmakers encode counter-narratives within institutionally legible genres, and how those narratives are decoded across the media ecologies that mediate their reception. The study concludes that Arab-Canadian cinema refuses equally the consolations of nostalgic return and the demands of assimilationist integration, developing instead a formal vocabulary - generic hybridity, archival poetics, testimonial intimacy - commensurate with the complexity of diasporic experience and constitutive of an enduring intervention in the politics of representation in multicultural Canada.Type d'Item : Item , Investigating Neurovascular Unit Aging in a Mouse Model of Autism(Université d'Ottawa / University of Ottawa, 2026-09-21) Humaid, Muath; Lacoste, BaptisteAgeing is the primary risk factor for most neurodegenerative diseases. While neurodevelopmental disorders, neuropsychiatric conditions, and neurodegenerative diseases are clinically expressed at different points during the lifespan and present distinct clinical features, these conditions share common cerebrovascular abnormalities. Growing evidence link cerebrovascular dysfunction to neurodegeneration, yet the early origins of these vascular impairments remain unclear. Identifying early changes is crucial for designing effective and/or preventive therapeutic strategies. This thesis aims to investigate neurovascular unit (NVU) ageing in a 16p.11.2 deletion (16p.11.2ᵈᶠᐟ⁺) mouse model of autism spectrum disorder (ASD). While we previously demonstrated that 16p.11.2ᵈᶠᐟ⁺ mice exhibit early-life NVU alterations, whether these initial deficits alter NVU ageing trajectory remains unknown. To answer these questions, we used multiple approaches to assess morphological and molecular NVU ageing. Using transmission electron microscopy to assess NVU characteristics in the cerebral cortex, we found that aged 16p.11.2ᵈᶠᐟ⁺ mice exhibit a pronounced, age-related decrease in the number of astroglia endfeet, a premature endfoot hypertrophy, and basement membrane thickening. Furthermore, immunohistochemistry for Glial Fibrillary Acidic Protein showed increased levels of reactive astrocytes in the stratum radiatum and stratum lacunosum-moleculare layers of the hippocampus CA1 region in middle-aged 16p.11.2ᵈᶠᐟ⁺ mice. Moreover, Aquaporin-4, a marker for water channel present in astroglial endfeet, displayed a premature decrease on vessels from aged 16p.11.2ᵈᶠᐟ⁺ mice. Collectively, our findings suggest a modified trajectory of ageing in this ASD mouse model and provide novel insights on NVU structural and morphological decline.
