Type d'Item : Item , Re-evaluating the South Cyclades Shear Zone, Ios, Greece(Université d'Ottawa / University of Ottawa, 2026-10-29) Salo, Camryn; Schneider, DavidMetamorphic core complexes (MCC) are large-scale extensional structures that exhume mid- to lower- crustal rocks beneath low-angle detachment systems and provide important insight into the processes of crustal deformation, metamorphism, and tectonic exhumation. The island of Ios, Greece, has long been regarded as a classic example of an MCC, where exhumation of the Cycladic Basement (CB) has traditionally been attributed to Miocene displacement along the so-called South Cyclades Shear Zone (SCSZ). However, the structural evolution of the island remains controversial due to the preservation of opposing kinematic indicators, and complex overprinting relationships. This study re-evaluates the tectonic evolution of Ios through detailed field mapping, structural analysis, petrography, and in-situ white mica ⁸⁷Rb/⁸⁷Sr geochronology. Emphasis is placed on the relationships between folding, foliation development, shearing, and the nature of the contact between the Cycladic Basement and Cycladic Blueschist Unit (CBU). Field observations demonstrate that both units preserve a pervasive schistose foliation (S₂) that is cut by a regionally developed axial planar cleavage (S₃), which overprints mineral assemblages and mylonitized fabrics. Opposing top-to-north and top-to-south kinematic indicators occur within the same lithologies, structural domains, and are commonly preserved with folded fabrics. These relationships suggest that many apparent kinematic reversals result from structural rotation during folding rather than recording discrete episodes of opposing shear. White mica in-situ ⁸⁷Rb/⁸⁷Sr geochronology from both units suggests a similar exhumation history, where retrograde related recrystallization occurred between c. 30-20 Ma, matching similar ages previously published for the island. The CB-CBU contact lacks a consistent strain gradient, metamorphic discontinuity, and structural continuity expected of a crustal-scale detachment zone. Instead, it is interpreted as a folded lithological boundary that shared a common tectonometamorphic and exhumation history. A younger top-to-north Headland Shear Zone locally overprints earlier fabrics and represents the latest recognized phase of ductile deformation on the island. Collectively, these observations challenge traditional interpretations of Ios as a classical metamorphic core complex and highlight the importance of structural inheritance, polyphase deformation, and fold-related modification of kinematic indicators when reconstructing the evolution of extended continental crust.Type d'Item : Item , Francophones’ Access to and Usage of French Language Public Services in Ontario Through a Social Resilience Lens(Université d'Ottawa | University of Ottawa, 2026-10-29) Leitch, Shannon; Veronis, LuisaThis thesis examines how Francophones across Ontario access and use French-language public services — specifically education, healthcare, and government services at the federal, provincial, and municipal levels. Drawing on data from a large-scale online survey of francophone residents (N = 1584) and a conceptual framework combining superdiversity and social resilience, the study compares patterns of service access across three regions of the province (Eastern, Central-Southwestern, and Northern Ontario) and between Canadian-born and immigrant Francophones, with finer-grained analysis of the Ottawa and Toronto metropolitan areas as the province’s two largest Francophone communities. Three dimensions of access are analyzed: the language used to access services, awareness of French-language service availability, and the perceived importance of being able to access services in French. The findings reveal that regionality is the most significant factor shaping access to French-language services, with a descending gradient of accessibility from federal to provincial to municipal levels that reflects the distinct legislative frameworks governing each. Among the service domains examined, education stands out for its high rates of French-language access and strong perceived importance, particularly among Canadian-born Francophones, for whom French-language education carries historical and ideological significance. Healthcare, by contrast, shows considerably higher rates of English-only access, suggesting a less continuous French-language service landscape in this domain. Migration status plays a secondary and context-dependent role: Canadian-born and immigrant Francophones within the same region show broadly similar access patterns, though notable differences emerge at the municipal level, where immigrants tend to place higher value on French-language services. Knowledge gaps represent a substantial but underrecognized barrier: nearly 80% of participants who accessed municipal services in English only were unaware that French-language options existed in their area. Despite these structural constraints, Francophones across the province overwhelmingly value access to French-language services, and many employ adaptive strategies—particularly bilingual service navigation—to maintain engagement with French where full French-language provision is unavailable. As one of the first studies to include both Canadian-born and immigrant Francophones within a single comparative framework, this thesis contributes systematic, cross-regional evidence to a field that has relied primarily on small-scale, locality-specific qualitative research, while accounting for how the geographic density of Francophone communities, their varying levels of institutional completeness, and their distinct demographic profiles shape service access across Ontario’s regions.Type d'Item : Item , Truck–Drone Collaborative Systems for Scalable Last-Mile Parcel Delivery(Université d'Ottawa | University of Ottawa, 2026-10-29) Cicek Simsek, Didem; Kantarci, BurakTruck–drone collaborative delivery (TDCD) has emerged as a promising approach to improve the efficiency and sustainability of last-mile logistics by combining the complementary capabilities of ground vehicles and unmanned aerial systems. Despite growing research interest, many existing studies rely on simplified operational assumptions, make limited use of empirically derived drone performance data, and give comparatively less attention to deployment conditions and user acceptance. This dissertation addresses these limitations through an integrated investigation of drone performance modeling, coordinated optimization, and behavioral adoption. This thesis develops a comprehensive, data-driven framework for the design and optimization of TDCD systems. At the operational level, an optimization framework is proposed to jointly optimize truck stop selection, customer assignment, and drone fleet allocation under realistic constraints, including limited fleet size and energy capacity. To capture drone performance more accurately, regression-based models are developed to estimate delivery time and energy consumption, and are integrated into the optimization framework. The framework is evaluated using real-world route data derived from the Amazon Last Mile Routing Research Challenge dataset (2021), ensuring practical relevance. Computational experiments and sensitivity analyses demonstrate that the proposed TDCD framework can significantly outperform conventional truck-only delivery systems, achieving substantial reductions in delivery completion time and total energy consumption while revealing diminishing returns beyond certain fleet sizes and infrastructure configurations. The results highlight the importance of coordinated decision-making across routing, resource allocation, and infrastructure design to maximize system performance and scalability. Beyond operational optimization, this thesis examines the behavioral dimension of drone delivery adoption through a questionnaire-based study grounded in an extended UTAUT2 framework. The findings identify performance expectancy, social influence, and perceived risk as key determinants of Canadians’ adoption intentions. By integrating optimization modeling, performance evaluation, and user acceptance analysis, this research advances understanding of TDCD and provides practical insights for developing scalable and sustainable last-mile delivery systems.Type d'Item : Item , The Negotiated Image: AI, Art, and the Unsettling of Photography(Université d'Ottawa | University of Ottawa, 2026-10-29) Sytsma, Sean; Paré, Daniel J.This thesis examines how relevant social groups negotiate the artistic legitimacy of photorealistic AI-generated imagery within contemporary photographic practice. Guided by the central research question, How do the intersecting views of artists, photographers, curators, and critics contribute to legitimating photorealistic AI-generated imagery as an authentic art form?, the study employed a qualitative design consisting of eleven semi-structured interviews with traditional photographers, producers of photorealistic AI-generated imagery, curators, and a critic. Interpreted through a Social Construction of Technology (SCOT) lens, the findings suggest that artistic legitimacy is negotiated through overlapping understandings of photography, authorship, artistic labour, intentionality, institutional recognition, and broader ethical concerns, rather than any singular technical, aesthetic, or ontological criterion. By focusing on photorealistic AI-generated imagery, this study advances ongoing debates concerning the place of such imagery within photography and contemporary artistic practice by demonstrating how these images complicate conventional distinctions between photography, digital image-making, and computational media.Type d'Item : Item , Exploring the Development of Diagnostic Reasoning Among Nurse Practitioner Students at Two Canadian Universities(Université d'Ottawa | University of Ottawa, 2026-10-29) Pirani, Sarah; Tyerman, JaneBackground Diagnostic Reasoning (DR) is a core competency for entry-level nurse practitioner (NP) practice and is fundamental to safe and effective clinical decision-making. Although numerous educational strategies have been proposed to strengthen DR, limited research has explored how NP students experience and develop DR throughout their educational journey. Purpose The purpose of this dissertation was to explore how NP students develop DR during their educational programs at two Canadian universities. Methods This qualitative dissertation employed Interpretive Description and comprised three interconnected manuscripts derived from a larger study. Twenty-four NP students in the final semester of their programs at two Canadian universities participated in semi-structured interviews conducted between May and June 2025. Interview transcripts were analyzed inductively using iterative coding, constant comparison, and Bingham’s five-phase qualitative analysis framework to generate clinically relevant interpretations. Results Across three manuscripts, the findings demonstrate that DR development extends beyond acquiring diagnostic knowledge and technical skills. Rather, it is the developmental process involving professional identity transformation, metacognitive growth, and learning within complex educational and clinical environments. Participants described the transition from registered nurses to NP as a shift toward diagnostic accountability while simultaneously developing the ability to calibrate intuition and analytical reasoning, recognize and regulate cognitive biases, reflect on clinical decision-making, and tolerate diagnostic uncertainty. DR development was further shaped by curriculum design, simulation, clinical preceptors, peer learning, and opportunities for deliberate practice. Conclusion This dissertation contributes a learner-centered understanding of DR development and addresses an important gap in NP education literature. The findings support explicit, longitudinal, and practice-oriented approaches to teaching DR that integrate classroom, simulation, and clinical learning experiences. These insights have implications for NP education, preceptor development, curriculum design, and future research aimed at preparing graduates for safe and independent diagnostic practice.
