Type d'Item : Item , Synthetic Topological Quantum Matter and Nanostructures for Topological Quantum Computing(Université d'Ottawa | University of Ottawa, 2026-06-12) Ghafour Mohseni, Mahan; Czischek , StefanieQuantum computers hold the promise of solving computational problems that are intractable for classical computers, by harnessing the principles of quantum mechanics. However, quantum computations are highly susceptible to noise and decoherence, which place strict limits on the size and depth of the circuits that can be reliably executed on current hardware. Topological quantum computing (TQC) has emerged as one of the promising approaches to building fault-tolerant quantum computers. The key idea is to store quantum information in the global properties of a physical system, making it naturally resilient to the local noise and errors that affect conventional qubits. This thesis focuses on synthetic topological quantum matter, the physical platform on which TQC is built, and investigates its electronic structure and topological properties. We study the conditions under which these systems enter a topological phase and host Majorana zero modes (MZMs), exotic zero-energy quasiparticles that appear at the boundaries of the system. MZMs are the key building block of TQC, as their quantum mechanical properties allow them to encode and process quantum information in a way that is protected from errors. We demonstrate the existence of MZMs in two canoni- cal topological systems, the Kitaev chain and the semiconducting-superconducting nanowire. To address the experimental challenge of detecting MZMs, we develop an optical spectroscopy technique based on excitonic interactions, which provides clear and measurable signatures of the topological phase. We also explore the variational quantum eigensolver as a quantum algorithmic approach to approximating the ground-state energy of the many-body spectrum of topological systems. Furthermore, we discuss the practical setups for topological quantum matter and simulate them through numerical analysis. Altogether, we present several theoretical and numerical methods that can be used for numerical simulations and practical purposes of detecting MZMs in topological quantum matter.Type d'Item : Item , The Geographies of Property Law: Engagement with Place and Space(Université d'Ottawa | University of Ottawa, 2026-06-11) Brown, Tenille E.; Judge, ElizabethThis PhD thesis takes up the topic of property law and the many ways that property is created, changed and redistributed through the law of expropriation. Situated within law and geography scholarship, this thesis adopts methods from geography, particularly physical geography, to interrogate places of expropriation. The law and geography study is of the place where an historic de facto expropriation – erstwhile called constructive expropriation – legal decision takes place. The geographic location is Kingsburg Beach, Nova Scotia; the legal decision is Mariner Real Estate Ltd. v. Nova Scotia (Attorney General), 1999 NSCA 98. Taking a place-based research approach to examine expropriation law and situating that law in a specific location highlights the geographies of property, which, I argue, expropriation law ought to focus on. These geographies are constituted by the past and present, the limits and affordances of the physical geography, and the importance of the type of location, which in the location examined, is a beach-place. First, this thesis constructs a law and geography research methodology and considers how it would apply it to property law broadly. Second, the thesis re-examines the law of expropriation – both de jure and de facto expropriation – through the lens of geography reframing expropriation law as a place-making tool. Third, the thesis examines the case study site from the perspectives of private property, environmental concerns, the publicness of the location, and Aboriginal land interests. Together these individual focal points guide an understanding of place as both complex and specific, and of the law of expropriation as the tool that affords a changing property landscape. Recent developments in the law of expropriation in Canada indicate that expropriation law remains under-examined and in need of critical interrogation. This PhD thesis undertakes such an interrogation and in doing so provides an important reframing of expropriation law, geography and place.Type d'Item : Item , Quality Assurance in Ontario Schools of Nursing(Université d'Ottawa / University of Ottawa, 2026-06-10) Guest, Elise; Moreau, Katherine A.This dissertation examines the quality assurance (QA) review processes in Ontario's Schools of Nursing (SoN), which undergo three distinct reviews: mandatory provincial and regulatory approvals and voluntary accreditation. Each review is intended to ensure program quality, but the overlapping requirements impose significant burdens on administrators, faculty and staff (known throughout as the interest holders). My study identifies redundancies, illustrates the human impact of the current system, and suggests improvements that could reduce burdens for SoN interest holders participating in the reviews. Through an explanatory, sequential two-part multimethod study, including document reviews, a survey, and interviews, my research highlights the benefits, barriers, and challenges of the current QA review requirements for interest holders in Ontario SoN. The findings reveal that, while QA reviews ensure that all SoN are held to consistent standards in their administration and programming, they create significant challenges for interest holders due to their repetitive nature, excessive workload, and the perception that they are not relevant to the contextual realities of Nursing education in Ontario. Interest holders recognize the theoretical benefits of the system, but they expressed frustration at how they experience it. My findings suggest that streamlining QA processes by identifying commonalities across reviews, adopting change management and resistance to change techniques, and developing integrated strategies for QA activities in Ontario's SoN is required for the sustainability of this work. My research contributes to the broader scholarship on QA in higher education (HE) and offers practical recommendations for the QA bodies and Ontario SoN. It emphasizes the need for improved collaboration between QA bodies and SoN to reduce inefficiencies, ensuring that QA remains sustainable in an era of resource constraints. Finally, it explores issues of resistance to change as a model for how interest holders resist QA activities and how to identify and counter the associated behaviours among them.Type d'Item : Item , Government funding and the location of charities in space and field of activity(2026-06-10) Devlin, Rose Anne; Tian, WenjieThe work examining how government funding affects entry and exit decisions by charities mainly focuses on specific cases, a more general empirical assessment has yet to be done. Our paper tries to fill this gap by looking at all the entries and exits of charities over the period 1990 to 2021 in Canada using the CRA T3010 data set. We examine these outcomes by census subdivision (CSD) area, allowing us to control for a wide variety of local influences obtained from confidential censuses. This study offers new empirical evidence on the role of government funding for the charitable sector, distinguishing between past, current, and anticipated funding exposure and how these can shape both formation and dissolution. We also examine how funding influences the mix of charitable services. Charity entry is positively related to the proportion of existing charities in the CSD receiving government support in the current year and the following one, suggesting that charities form when current and anticipated funding environments are favourable. Exit decisions are most sensitive to funding deprivation in the previous year, particularly for charities in the areas of ‘Relief of Poverty’ and ‘Community’, highlighting that dissolution tends to reflect lagged financial strain rather than contemporaneous or expected conditions, and the heterogeneous impact of such strain by field of activity.Type d'Item : Item , Au nom du père et du fils : le catholicisme et la masculinité dans le théâtre francophone du Canada(Université d'Ottawa | University of Ottawa, 2026-06-09) Gauthier, Alexandre; Hotte, LucieCette thèse réfléchit à la présence de l’imaginaire religieux catholique dans la dramaturgie québécoise et franco-canadienne contemporaine et, en particulier, à son incidence sur la construction des personnages masculins dans l’œuvre de Michel Marc Bouchard (Québec), Rhéal Cenerini (Manitoba), Herménégilde Chiasson (Nouveau-Brunswick) et Michel Ouellette (Ontario). L’imaginaire religieux déployé dans les œuvres du corpus permet de constituer un cadre interprétatif à partir duquel comprendre les personnages masculins. En s’appuyant à la fois sur une approche socio-sémiotique et dramaturgique, cette thèse s’attarde surtout sur les fonctions du religieux dans les pièces à l’étude. Le premier chapitre se concentre sur la fonction du religieux qui apparaît comme la plus évidente, soit la fonction référentielle. En effet, les multiples allusions au catholicisme dans les œuvres du corpus contribuent activement à la construction d’un cadre spatio-temporel précis, instaurant un rapport étroit à l’espace canadien-français, mais surtout à l’Histoire. Ce rapport, plus ou moins réaliste selon l’exploitation de la matière religieuse et la manière dont les œuvres s’inscrivent dans l’imaginaire, suggère une relecture originale du passé canadien-français et une réactualisation de certains tropes religieux qui éclairent le présent. Quant au deuxième chapitre, il s’intéresse davantage à la fonction structurante du religieux, tant sur le plan formel et dramaturgique que sur le plan du contenu. Les pièces analysées entretiennent avec la Bible un rapport intertextuel important, qui se traduit tout particulièrement sur les plans thématique et formel. Les auteurs empruntent en effet à la Bible, mais à d’autres formes littéraires ou liturgiques (le mystère médiéval, la messe de requiem, le chemin de croix) leur armature prédéfinie. Plus qu’une contrainte d’écriture, ce recours au religieux comme élément structurant de leurs textes dramatiques les inscrit dans une tradition à la fois religieuse et théâtrale, symbolique aussi, et suggère en même temps un cadre interprétatif précis. Enfin, le dernier chapitre se penche sur le rôle du religieux dans la construction des personnages masculins. Les œuvres analysées présentent différents types de personnages masculins dont la caractérisation est influencée à la fois par le rôle référentiel et par le rôle structurant du religieux. En effet, quelques textes dramatiques analysés proposent une variation de la figure christique, tandis que d’autres puisent dans l’Ancien Testament et font intervenir Abraham ou Isaac. Toutes ces références à ces figures paternelles ou filiales influencent inévitablement les diverses relations qui se déploient dans les textes analysés, tant dans leur construction que dans leur interprétation. Le corpus met également en scène des membres du clergé qui sont à la fois le fruit de leur société, mais aussi des valeurs de l’institution à laquelle ils appartiennent. Cette thèse met donc en lumière l’importance du religieux et du catholicisme culturel dans la création d’œuvres dramatiques écrites par des auteurs nés autour de la Révolution tranquille. Elle contribue à cartographier l’imaginaire religieux déployé dans ces textes, à le mettre en contexte et à constituer l’encyclopédie dont le spectateur a besoin pour bien recevoir ces œuvres à cette époque séculière.
