Working in a family counselling program in an Indigenous child welfare agency
No full textThis report focuses on my advanced practicum experience with Kina Gbezhgomi Child and Family Services (KGCFS). KGCFS is a multi-service child welfare agency that was created and is governed by the seven First Nations on Manitoulin Island, providing Indigenous child welfare services for First Nation people living on Manitoulin Island and in the Sudbury Manitoulin District. The focus of this advanced practicum was to gain more experience and knowledge as a clinical practitioner and family counsellor in an Indigenous child welfare agency through an anti-colonial approach. These elements included working in an anti-colonial way, learning from Indigenous knowledge, critiquing mainstream theories, as well as learning more about Indigenous culture, self-care, and being an ally. This report includes a review of the literature that I read throughout the placement and a description of what I learned from my practicum experience with the In-Home Family Support Team
Challenging perfectionistic cognitions and body talk : a preventive approach to reduce appearance-related harm in youth
No full textThe present study sought to extend previous research by Henry (2022), which found that individuals higher in perfectionism did not benefit to the same extent from body talk interventions as those lower in perfectionism following body talk exposure. This study examined whether adding a perfectionism-focused component to a body talk intervention could reduce the detrimental effects of body talk exposure among youth higher in perfectionism. Participants included North American young women (N = 146) and men (N =67), aged 13 to 24, who were randomly assigned to one of three conditions: a body talk intervention, an extended intervention (incorporating both body talk and perfectionism-focused components), or a control condition. While significant interactions were limited, women higher in worry about imperfection benefited most from the body talk intervention, reporting higher body satisfaction and lower negative affect compared to the control group. In contrast, no such effects were observed in men, and the extended intervention did not yield additional benefits, perhaps because a single session was insufficient to shift ingrained perfectionistic patterns. Across genders, perfectionism predispositions, particularly worry about imperfection and socially prescribed perfectionism, were consistently linked to poorer body image outcomes. Self-oriented perfectionism predicted negative outcomes in women only. These findings highlight gender differences in intervention effectiveness and emphasize the need for multi-session programs, as well as increased inclusion of men in body image research
Bubble formation and growth In superheated liquid bubble chambers
No full textBubble chambers are a type of particle detector that make use of the superheated state to detect minute energy depositions. Early studies of nucleation in bubble chambers provide evidence that, if sufficient energy is deposited within a region of the superheated liquid, it triggers nucleation of a spherical protobubble that will grow and become a visually observable bubble whilst emitting an acoustic impulse. The acoustic emission of alpha particle-induced bubbles are readily distinguishable from those produced by lower-energy neutron scattering events. This thesis investigates the nucleation of bubbles and the associated acoustic emissions in superheated liquids, with a focus on understanding the nature of the differences in acoustic emissions produced by different types of particles. Using molecular dynamics simulations, we successfully replicated a superheated liquid state using a Lennard-Jones potential to model the C3F8 molecule. We also successfully triggered nucleation by low-mass high kinetic energy projectile from within the superheated liquid. This process mimics what is believed to occur in superheated liquid such as C3F8, which is used in PICO bubble chambers, where either a fluorine or carbon nucleus recoils with sufficient kinetic energy to trigger the nucleation process. The simulations show that bubbles nucleated in close proximity grow independently of each other throughout the coalescence. This supports a long-standing hypothesis that energy deposition from particles can be modeled as a track of non-interacting protobubbles that will grow into the singular observed bubble. Furthermore, within the limitations of particle transport software, we modeled the fragmentation of molecules, a process that is believed to occur during the energy deposition of particles, which could be used to explain the observed nucleation efficiencies in PICO detectors. Furthermore, from numerical simulations we were successful in using the total change in volume with respect to time to model the acoustic emissions and reproduce observations in PICO detectors. The protobubble model was used to further investigate partial energy depositions near the walls of the detector and from particulates. The acoustics of partial alpha energy depositions can be reduced to those of low energy nuclear recoils, which justifies removing events that occur near the walls of the detector from any analysis. In addition to studying nucleation, simulations of neutron exposures in the PICO-40L detector were compared with data, in agreement with the conventional nucleation model involving nucleation efficiencies of recoiling nuclei. The simulations predicted the ratio of the number of multiple bubble to the number of single bubble events (MSR) to be 3.0±0.2, in agreement with the observations. Finally, simulations of gamma exposures will be compared to experimental data to identify potential temperature profiles within the detector, as the nucleation model relevant to electrons produced by the passage of gamma in the superheated liquid is sensitive to variations in the nucleation threshold energy, which is influenced by temperature
Étude empirique de l'étendue du progrès en lecture anticipée chez l'élève franco-ontarien de la 1re à la 4e année
No full textL'objectif de cette étude est d'évaluer les progrès en lecture des élèves francophones du primaire vivant en contexte minoritaire dans le nord de l'Ontario, en mesurant le nombre de mots lus correctement par minute (#MLC/M). Inspirée du protocole de Hasbrouck et Tindal en 2006, cette étude concerne un échantillon de 150 élèves appartenant au Conseil scolaire du Grand Nord, qui ont été soumis à la lecture de deux livres gradués à trois moments clés au cours de l'année scolaire 2023-2024. Les séances ont été enregistrées via Zoom et ont fait l'objet d'une analyse quantitative. Les U de Mann–Whitney ont mis en évidence des différences significatives entre le rendement en lecture des élèves en fonction de la langue de communication au foyer, la réussite des francophones étant supérieure aux anglophones), et d’une façon particulièrement marquée en 4e année. Elles ont également montré que les disparités de résultats varient selon la langue utilisée à la maison et la complexité croissante des textes.
Cette recherche met en évidence l'importance de développer des normes de lecture spécifiques au contexte francophone, en prenant en considération les aspects linguistiques, culturels et cognitifs qui impactent l'acquisition de la fluidité en lecture
Étude du développement de la pensée critique chez les élèves de l’élémentaire issus de la première génération d’immigrants africains : points de vue des enseignants et enseignantes de l’Ontario
No full textCette recherche doctorale s’intéresse au développement de la pensée critique chez les élèves de l’élémentaire issus de la première génération d’immigrants africains dans le système éducatif ontarien. Dans un contexte marqué par la diversité culturelle, elle explore les mécanismes didactico-pédagogiques mobilisés par les enseignant.e.s pour favoriser cette compétence essentielle, reconnue pour son rôle transversal dans la réussite scolaire et la préparation à la citoyenneté active. Inscrite dans une posture épistémologique herméneutique, l’étude adopte une approche qualitative pour interroger les conceptions, les stratégies pédagogiques et la prise en compte de la culture des élèves dans les mécanismes de développement de la pensée critique.
Les résultats révèlent une pluralité de conceptions de la pensée critique, oscillant entre une approche psychopédagogique, centrée sur le développement progressif de compétences, et une approche philosophique, fondée sur le questionnement et le jugement éclairé. Les stratégies pédagogiques identifiées s’inscrivent dans une logique active et pédocentrique, où l’élève est considéré comme un acteur réflexif et autonome de son apprentissage. Cette approche vise le développement global de l’enfant, en tenant compte de ses besoins, intérêts et rythmes d’évolution. Cependant, l’étude met en lumière une prise en compte encore marginale du facteur culturel dans l’enseignement de la pensée critique. Les pratiques observées demeurent souvent génériques et peu contextualisées aux réalités des élèves immigrants africains, ce qui peut limiter leur accès à une pensée critique authentique. En s’appuyant sur une perspective sociologique et interculturelle, la recherche souligne l’importance de valoriser les parcours migratoires et les ressources cognitives des élèves issus de la diversité.
Enfin, cette étude propose des pistes pour de futures recherches, notamment l’observation directe des pratiques en classe, l’exploration du point de vue des élèves, et le développement d’outils didactiques contextualisés. Elle plaide pour une éducation inclusive et équitable, capable de promouvoir une véritable justice cognitive et de faire de l’école un lieu d’émancipation intellectuelle
Nishnaabenaadziwin Aabaakwigaade: designing a cultural centre in Nipissing First Nation
No full textIndigenous peoples represent a resilience, rooted in their collective resistance to forced assimilation efforts imposed by colonization. This resilience is seen through their revival and reclamation efforts. This thesis explores integrating Indigenous traditional knowledge of culture and tradition into the contemporary architectural design for a cultural center proposal for Nipissing First Nation(Nbisiing) in designing a space that supports the cultural exchange of arts, crafts, language, culture, and tradition for the community. The study investigates different architectural case studies and land-based learning to inform the design of a culturally responsive proposal that recognizes the deep connection between First Nation communities and their environments. The research investigates how architectural spaces can reflect this revival and reclamation through sustainability, cultural heritage, and communal learning. This thesis responds to, “How can a cultural center be designed to support the cultural revitalization, identity, and knowledge-sharing needs of Nipissing First Nation through a decolonized, land-based architectural process that integrates Nbisiing traditional knowledge and values?” This work advocates for respecting and revitalizing Indigenous ways of knowing in architecture, contributing to a broader discourse of decolonizing designs
Review, redesign, repurpose: improving the methodology of repurposing unused commercial office buildings
No full textThis thesis explores how to improve the existing process of commercial office conversion models to develop a long-term solution to mass vacancy rates in mid-sized Ontario cities. An analysis of how these systems operate reveals that they are insufficient to address the needs for which they are designed, lacking insight and adaptability. Mid- sized cities consistently possess masses of prominent vacant properties that accentuate city-wide issues. The proposed conversion model prioritizes consistent long-term success through less exclusionary selection of location, prioritization of modern living styles, better utilization of environmental systems, and flexible walling types to create properties that can constantly adapt to the changing needs of the local community. The proposed model would also provide different tiers of conversion to ensure versatility for the building owners, regardless of financial means. This model is then implemented upon a vacant building within downtown Sudbury, with the different levels of conversion demonstrated
Contributions in nearly non-diffracting beams' propagation
No full textDue to their unique properties, non-diffracting beams, such as Bessel beams, are increasingly used in various biomedical, imaging, research, and industrial applications. In this thesis, I present designs for two types of optical systems that generate nearly non-diffracting beams. The first system produces a quasi-nondiffracting light sheet, while the second explores different methods for generating constant intensity, constant DOF, tunable range, Bessel beams. The motivations behind this work, potential applications of the developed systems, and a review of the relevant literature and background theory are discussed. The main proposed ideas to achieve these goals are also presented and analyzed. The research includes mathematical descriptions and numerical simulations of the developed systems. An experimental realization of the light sheet system is described, with the results presented and discussed. To generate the light sheet, we propose a setup comprising a laser, a telescope to expand and collimate the laser beam, a Powell lens to expand the beam in the spanwise direction, and a mask on a cylindrical lens. The mask, formed by a pair of double slits, works with the cylindrical lens to produce a thin, nearly non-diffracting light sheet. For generating constant intensity, constant DOF, tunable range, Bessel beams, we propose three optical systems. The first system consists of three refractive axicons: the first two axicons create a nearly constant-diameter annular beam, and the third, a logarithmic axicon, generates a nearly constant intensity segment of light. The tunability is achieved by adjusting the distance between the first two axicons. The second system employs a newly designed optical lens to transform an annular beam into a Bessel beam with a constant intensity, constant DOF, and tunable range. The third system involves placing a ring aperture in front of a logarithmic axicon. The tunability is achieved by varying the mean radius of the ring aperture
Integrated care for perinatal opioid use in rural and northern Canada: an integrative review
No full textAlthough perinatal opioid use is relatively rare, geographic disparities in prevalence exist in Canada. The maternal and infant health risks are exacerbated by social determinants of health (SDH) such as poverty, trauma, and healthcare access. Integrated care (IC) models, which coordinate health and social services, offer promise but remain underexplored in rural perinatal contexts. This integrative review assesses how IC models address SDH and influence access to care for pregnant individuals using opioids in rural settings. Using Whittemore and Knafl’s methodology, a systematic search identified 23 articles covering 10 IC programs. Eight themes emerged, including scope of care; culturally grounded models; SDH in rural and northern communities; intersectionality; mitigating SDH; rural–urban differences; health and social outcomes; and barriers and enablers to integrated service delivery. Findings and recommendations may inform trauma-informed, equity-focused IC models that address intersecting SDH and improve maternal–infant outcomes in marginalized communities
Exploring the lifelong impact of significant outdoor life experiences: retrospective methods, theoretical frameworks, and professional trajectories in outdoor learning
No full textThis dissertation examines the impact of early outdoor experiences on the careers and lives of outdoor professionals, employing retrospective research methods. While prior studies in Outdoor Learning (OL) have focused on program delivery and group development, recent trends emphasize secondary outcomes, such as social integration, life development, and well-being benefits, that have lasting effects. Despite some promising findings, the research on lasting outdoor outcomes is still in its early stages and is limited by a lack of studies and methodological constraints.
This study aims to address three research questions to advance this field of research: (1) What are the current methodologies and suggested best practices for conducting retrospective research in outdoor learning? (2) What are the prominent theoretical frameworks supporting retrospective research in OL? (3) What are the characteristics of early life outdoor experiences that led to lasting outcomes and motivate the life trajectories of outdoor professionals? A retrospective scoping review and a theoretical framework narrative analysis preceded an empirical study that included a questionnaire and focus groups to answer research question three.
The scoping review and narrative analysis revealed a significant gap in the literature, with most studies emphasizing short-term program evaluations rather than long-term or holistic outcomes of OL. These findings underscore the need for empirical, retrospective research employing mixed methods to capture the lasting impacts of outdoor experiences more effectively. When situated within the frameworks of Significant Outdoor Life Experiences (SOLE) and Life Course Theory (LCT), such an approach offers a promising means of identifying self-reported outcomes related to identity, career development, and well-being.
Results from the scoping review affirmed the relevance of the SOLE framework for capturing the lasting impact of early outdoor experiences on subjects’ identity, well-being, and life trajectories. Qualitative findings revealed that SOLEs fostered professional development, personal growth, and holistic health, with many subjects identifying them as transformative or trajectory-altering moments. Key predictors of long-term impact included experience, duration, and alignment with personal values, social connection, and identity formation
