  Background: Community-campus engagement (CCE) refers to collaborative partnerships between academic institutions, municipalities, and community organizations that has the potential to address population health issues. This thesis sought to describe how knowledge is translated within CCE and identify the barriers and facilitators to the knowledge translation (KT) process. Methods: We conducted an exploratory, qualitative study, interviewing 39 instructors, students, city staff, and community organization staff involved in CCE projects, and using a semi-deductive, semi-inductive analysis approach. Results: Four distinct phases of KT arose within the model of CCE we examined: knowledge co-production, knowledge tailoring, knowledge sharing, and knowledge application. Partner engagement, diverse knowledge sources, and connection to place facilitated KT, while several logistical, contextual, relational, and systemic factors emerged as barriers. Conclusions: Interest-holders may consider adopting a purposeful KT approach within CCE that prioritizes bridging the gap between knowledge production and use.

  Cette thèse porte sur les dynamiques identitaires et l'action publique dans les métropoles où coexistent, sur un même territoire, plusieurs cadres de pensée en matière d'inclusion des immigrants et des minorités ethnoculturelles. Elle compare les cas de Bruxelles et Montréal, deux villes linguistiquement divisées et cosmopolites, où les politiques d'inclusion sont traversées par des tensions entre différentes conceptions de l'appartenance. En adoptant une approche inspirée du néo-institutionnalisme sociologique, la thèse analyse la relation entre identités collectives, cadres de pensée en matière d'inclusion et instruments d'action publique. À partir de 83 entretiens semi-dirigés, elle étudie la saillance des identités bruxelloise et flamande, dans le premier cas, et montréalaise, québécoise et canadienne, dans le second. Elle analyse également la manière dont les acteurs responsables des politiques d'inclusion se représentent les éléments constitutifs de ces identités, de même que les paramètres et les attentes qui structurent les cadres de pensée qui leur sont associées. Enfin, elle examine la correspondance entre ces cadres et les instruments d'action publique produits par les institutions bruxelloises et par la Ville de Montréal. La thèse propose un cadre d'analyse cognitif et relationnel permettant d'appréhender différemment les politiques d'inclusion. D'une part, elle apporte une nuance importante à la littérature sur les modèles nationaux d'intégration en montrant que les identités urbaines peuvent alimenter des cadres de pensée en matière d'inclusion qui divergent des principales approches nationales et étatiques. D'autre part, elle invite à relativiser les conclusions des travaux sur le tournant local des politiques d'intégration. Plus spécifiquement, elle montre que les politiques élaborées par les municipalités sont loin d'être pleinement autonomes et qu'elles s'inscrivent plutôt dans des dynamiques relationnelles avec les autres ordres de gouvernement.

  The Collaborative Design, Implementation, and Evaluation of a Mental Health Strategy with Tennis Canada: Value and Recommendations

  (Université d'Ottawa / University of Ottawa, 2026-09-14) Papich, Mikaela; Durand-Bush, Natalie

  The sport ecology plays a crucial role in promoting and optimizing the mental health (MH) of athletes, coaches, and staff (Henriksen, Huang, et al., 2024; Purcell et al., 2019; Schinke et al., 2024). Recognizing this responsibility, the Mental Health Strategy for High Performance Sport in Canada (the "national MH Strategy") was developed to provide a roadmap for sport organizations to improve MH outcomes within their communities (Durand-Bush & Van Slingerland, 2021). The national MH Strategy outlines five priorities (1-leadership, 2-promotion, 3-prevention, 4-treatment, 5-monitoring), which should be adapted to meet the needs of individual organizations. Despite providing valuable recommendations, there remains a lack of empirical evidence to guide this process, creating a significant challenge for sport psychology practitioners (SPPs), researchers, and organizations wanting to implement system-wide MH initiatives (Prior et al., 2024a). The purpose of this Participatory Action Research (PAR) project was to collaboratively design, implement, and evaluate a sport-specific version of the "national MH Strategy" with Tennis Canada (TC) leaders. A Core Leadership Team (CLT; n = 5-8) and Task Force (TF; n = 21) were recruited for all three phases (Design, Implementation, and Evaluation) of the project. This project was also conducted in partnership with Game Plan, Own the Podium, and the Canadian Centre for Mental Health and Sport (CCMHS).These participants were positioned as experts through their lived experience (Bergold & Thomas, 2012), facilitating the co-creation of knowledge to develop a contextually relevant strategy that addressed the specific needs of TC's community, and providing insight into the implementation and evaluation. Individuals were strategically recruited to represent different levels (e.g., provincial, national) and groups (e.g., parents, coaches, senior leaders, MH practitioners) of TC's sport ecosystem, using an Ecological Systems Model (Durand-Bush & Van Slingerland, 2021; Purcell et al., 2019). A multiphase qualitative design was used to carry out three objectives: (a) collaboratively design a sport-specific version of the national MH Strategy with TC (herein referred to as "TC's Strategy") with a CLT and TF, (b) track the implementation of TC's Strategy over one year, and (c) evaluate what TC accomplished in one year and assess the Strategy's intrinsic and extrinsic value. Data were collected using a Needs/Gap Assessment, group discussions, semi-structured interviews, an Implementation Progress Chart, and a reflexive journal. The research culminated in three distinct but related studies and three articles. -- Design Phase (Study 1): The purpose of Study 1 was to collaboratively design a sport-specific version of the national MH Strategy with TC leaders. To achieve this, a CLT of five members and a TF of 21 members representing TC's community were recruited. The CLT and TF participated in four formal meetings and completed a Needs/Gap Assessment over an 11-month period (June 2022 - May 2023) to co-create the knowledge required to design TC's Strategy. The Needs/Gap Assessment allowed participants to identify which aspects of the national MH Strategy were most relevant to TC and reflect on sport-specific risk and protective factors, resource availability (e.g., human, financial), timelines, and barriers. A directed content analysis generated data organized under an Early, Middle, and Late Phase of the 11-month period. The Early Phase served to analyze the first two TF group discussions and the Needs/Gap Assessment data, resulting in five first-level codes (the five priorities), 12 second-level codes (e.g., service provision, help-seeking, assessment), and 32 third-level codes presented as actions (e.g., use a phased-in approach over a 3-year period, Wellness Director leads implementation of TC's Strategy). The Middle Phase involved transforming the data into the first version of TC's Strategy and obtaining feedback from the TF during the third TF group discussion. The Late Phase involved finalizing TC's 5-priorities, 18-objectives, and 45-actions Strategy and receiving final input from the TF during the fourth TF group discussion. Given the scope and breadth of the Strategy, the plan was to implement the Strategy over three years, with the first year focusing on Priorities 2 and 3, and the target population of TC coaches and staff, and National Tennis Centre athletes and parents. Success factors and challenges were provided along with recommendations to support other organizations wishing to create plans to improve system-wide MH outcomes. Importantly, a Wellness Director was hired in April 2023 and tasked to lead the implementation of TC's Strategy. -- Implementation Phase (Study 2): The implementation Phase began when TC's Strategy was officially launched in February 2024. Building on Study 1, the purpose of Study 2 was to explore leaders' perspectives on the first year of implementation of TC's Strategy, which occurred between February 2024 and February 2025. The CLT was expanded to eight individuals for additional representation. Sixteen TF members participated in this phase, including the eight CLT members. Data were collected using one TF and 12 CLT group discussions, 11 individual semi-structured interviews, and a reflexive journal. Additionally, the Research Project Lead (RPL) engaged in over 40 meetings with the Wellness Director and Director, High Performance Programs, to track implementation progress and provide input where needed. The reflexive thematic analysis led to the identification of three main themes. The first theme pertained to the leaders' perceived experiences and outcomes, and more specifically, the positive benefits of participating in this phase of the research process (e.g., engagement, learning, support). The second theme related to influential factors that impacted the first year of implementation (e.g., leadership, promotion, implementation framework, wellness and recovery). The third theme comprised recommendations to continue improving the implementation of the Strategy and to close perceived gaps (e.g., organizational change, education). Based on evolving needs and emerging MH initiatives, and supported by the PAR approach, TC's Strategy expanded from 45 to 71 actions throughout this phase. Findings provide relevant insights into how a sport organization can harness diverse leaders to implement MH initiatives and prioritize MH at the organizational level. -- Evaluation Phase (Study 3): The Evaluation Phase was initiated in March 2025, after the end of the Implementation Phase. The purpose of Study 3 was to examine what TC accomplished in the first year of implementing their Strategy and its intrinsic (merit) and extrinsic (worth) value. The eight-member CLT and 13 members of the 21-member TF participated in this phase. Data were collected between March 2025 and June 2025 using group discussions (three with the CLT; one with the TF), six individual semi-structured interviews with the CLT, an Implementation Progress Chart, and a reflexive journal. The group discussions and interviews served to gather TF and CLT feedback to inform the evaluation. The Implementation Progress Chart was developed by the Wellness Director and the RPL to provide a visual representation of what TC accomplished in the first year of implementation, to support the evaluation. The reflexive journal was used to maintain an audit trail and record reflexive entries. A directed content analysis revealed that TC completed 66 out of the 71 actions (93.0%) in their Strategy. In order of percentage, TC completed 100.0% (8 actions) in Priority 5, 95.7% (22 actions) in Priority 2, 92.3% (12 actions) in Priority 3, 88.9% (16 actions) in Priority 1, and 88.9% (8 actions) in Priority 4. The intrinsic value of the Strategy was described as a cultural shift within TC's community, wherein there was greater MH awareness, reduced stigma, and greater integration of support for athletes, parents, and staff. The extrinsic value was demonstrated through a perceived influence on individuals and organizations beyond TC, such as the international players who competed at the annual National Bank Open tournament hosted by TC, international tournaments (e.g., professional Grand Slams), and the Canadian high performance sport community (e.g., other sport organizations). A context-specific logic model was developed to synthesize the Strategy's inputs, activities, contextual influences, and outcomes, illustrating how TC targeted individual, relational, and organizational dimensions of the sport environment to support athletes, parents, coaches, and staff. Findings support the value of an ecological MH strategy within and beyond a sport organization. Overall, the current research fills a significant gap, providing empirical evidence on designing, implementing, and evaluating a sport-specific MH strategy using the national MH Strategy as a roadmap. It underscores the importance of engaging a representative and diverse leadership group, having a designated person to lead the implementation of the Strategy, phasing in the Strategy by targeting a smaller population and focusing on one or two priorities, and tracking the perceived outcomes to improve the Strategy. This project also shows the value of adopting a flexible PAR approach to engage a group of leaders in co-creating a meaningful strategy that serves the needs of a sport organization. Finally, it shows the utility of using theoretical frameworks (e.g., Ecological Systems Model) to guide MH initiatives, ensuring decision-making is informed by best practices and research recommendations.

  A Planning-Scale Permafrost Hazard Susceptibility Framework for Municipal Development Review in Iqaluit

  (Université d'Ottawa / University of Ottawa, 2026-09-14) Said Hassan, Sahra; Martín-Pérez, Beatriz; Wang, Di; Saulick, Yunesh

  Permafrost conditions strongly influence ground performance in Arctic communities, yet thaw related land information is not always available in a form City planning and development review staff can readily use. In Iqaluit, development review occurs within a context shaped by housing pressure, servicing constraints, climate change, and spatially variable permafrost. This thesis addresses the need for a planning-scale spatial reference that helps staff consider permafrost thaw related susceptibility as proposals are assessed against planning policies, by-laws, City objectives, and technical and safety requirements. The thesis develops a planning-oriented framework for producing a Permafrost Hazard Susceptibility Index (PHSI) and displaying the resulting classes through a planner-facing overlay for the populated area of Iqaluit, Nunavut. Using an applied, qualitative, single-case design and document analysis, it brings together literature on permafrost processes, susceptibility mapping, engineering standards and guidance, and Iqaluit's policy and development review context. The review considers subsurface physical, thermal, and mechanical conditions together with snow, vegetation, surficial geology, topography, drainage, and hydrology. The framework distinguishes thaw potential from thaw impact. The Thermal Response Index (TRI) and Ground Thermal State (GTS) form a Thaw Potential Index (TPI), which is combined with a Thaw Impact Index (TII) to produce the PHSI. It explains how mapped and local technical evidence can be rated, combined, classified, calibrated, and validated. It also distinguishes baseline and future ground conditions, sets minimum evidence requirements, reports confidence separately, and retains Unknown / Insufficient Data where a class cannot be supported. An illustrative application shows how baseline and future PHSI classes could inform discussions during the City's planning and development review process concerning height and density, servicing, development intensity, further geotechnical investigation, and mitigation. The study does not produce a calibrated operational map or replace site-specific investigation, engineering design, expert judgement, or decisions made through that process. Rather, it provides a transparent planning-scale framework for translating scientific, engineering, and planning knowledge into a practical reference for a thaw-sensitive northern city.

  Total Synthesis of (+)-Anhydrohavellockate and the Tetracyclic Core of Cembranoid Natural Products

  (Université d'Ottawa / University of Ottawa, 2026-09-14) Normandin, Chad; Barriault, Louis

  Polycyclic cembranoid and norcembranoid natural products are congested, highly oxygenated natural products found in multiple marine sponges, and as of today, their synthesis remains a significant challenge for organic chemists. As well as being of great interest to biologists and medicinal chemists for their interesting medicinal applications, these natural products can certainly pique curiosity for the curious synthetic chemist seeking a challenge. In that optic, havellockate, one of the most complex members of this family of natural products, was chosen for the target of this research thesis. We herein report a highly efficient enantioselective gram-scale synthesis of the tetracyclic core of (+)-havellockate as well as the total synthesis of (+)-anhydrohavellockate. The chemistry developed in this thesis can also be applied to the divergent synthesis of other higher order cembranoid and norcembranoid natural products such as mandapamate, confertdiate, dissectolide and plumarellide. Stemming off of the Barriault laboratory's expertise in gold catalysis, an initial racemic model substrate was targeted, seeking to construct a simplified version of the tetracyclic core of these natural products. The initial hypothesis was to build a linear fragment that would react multiple times with itself in a stereocontrolled manner upon treatment with an AuI catalyst. During the assembly of this linear fragment, the desired tetracyclic core target could be isolated, a serendipitous discovery that skyrocketed the efficiency of this synthesis. Upon this discovery, an enantioselective synthesis of this tetracyclic structure was initiated, and after much optimisation, the enantiopure polycyclic structure could be accessed in a stereocontrolled manner. A linear substrate was assembled, and when exposed to Sonogashira cross-coupling conditions, a spectacular reaction cascade was observed. This cascade was thoroughly studied and underwent five chemical transformations in a single pot, which generated the tetracyclic core of the natural product havellockate in a single operation. This chemistry was developed to be applied on gram-scale and furnished plenty of material for the required late-stage transformations. The last two transformations required to access the natural product, however, proved challenging, and multiple strategies were explored. Multiple protocols for the required penultimate alkene isomerisation were developed and ultimately succeeded, yielding the product (+)-anhydrohavellockate in 11 steps in the longest linear sequence from commercially-available TMS acetylene. The installation of the last oxygen atom, however, resisted all of our efforts, so far. In total, this work sums of five years of efforts, where we studied a spectacular reaction cascade that stereoselectively constructed the tetracyclic core of the natural product (+)-havellockate through 5 distinctive steps that were carefully choreographed by clever chemical design and rationale. This work effectively achieved the enantioselective total synthesis of (+)-anhydrohavellockate in 11 steps from commercial reagents.
