description: Employing a representative sample of small- and medium-sized enterprises, this study examines the performance of immigrant-owned business ventures (IBVs) and firms owned by non-immigrants. The study also presents a comprehensive profile of Canadian IBVs. Anecdotal evidence has suggested that many successful growth-oriented firms have been started and managed by immigrant entrepreneurs. Immigrant business owners are also thought to bring to business start-up unique managerial acumen and social capital derived from diverse experiences and international networks. To date, however, there remains a lack of substantive evidence regarding the performance of immigrant-owned ventures. The study also considers the performance of comparable groups of new firms owned by non-immigrant entrepreneurs, with a particular focus on the relationship between firm internationalization and enterprise performance. The results lend support to arguments that owner-level factors influence the process of internationalization among SMEs and that, compared to non-immigrant business owners, immigrant business owners retain entrepreneurial acumen that is conducive to the internationalization of young ventures. The implications of the findings for research and policy are considered.
Photoluminescence Spectroscopy of CdSe/Cd[0.5]Zn[0.5]S Core/Shell Colloidal Quantum Dots

description: The photoluminescence (PL) of dense aggregates of CdSe/Cd0.5Zn0.5S core/shell colloidal quantum dots (cQDs) was investigated to gain insight into bleaching processes, quantum efficiency behaviour, band gap energy temperature dependence, and the phonon-coupling contribution to thermal broadening. This work also encompassed a study of various sample preparation techniques. These newly investigated strain-engineered core/shell cQDs, having an effective lattice constant in between that of CdS and ZnS, fosters the study of novel properties not present in the previous two systems. The bleaching behaviour, studied subject to strong optical pumping for different external cQD environments, showed effective shell passivation, thus limiting non-radiative processes mainly to the core or shell structures. The relative quantum efficiency was determined as a function of temperature, showing two distinct regimes, with activation of a phonon process above ~ 180 K. The band gap energy was found to follow the empirical Varshni relation describing the temperature dependence of a semiconductor material, dominating any thermally induced changes of the cQD volume and confinement potential. The PL spectral width change with temperature showed highly coupled carrier-phonon scattering behaviour.

description: The D1-class receptors (D1R, D5R) each possess distinct signaling characteristics; however, pharmacological selectivity between them remains elusive. The third intracellular loops (IL3) of D1R and D5R harbour divergent residues that may contribute to their individual signalling phenotypes. Here we probe the function of central region of IL3 of D1R and D5R using deletion mutagenesis. Radioligand binding and whole cell cAMP assays suggest that the N-terminal and C-terminal moieties of the central IL3 oppositely contribute to the constitutive and agonist-dependant activity of D1-Class receptors. Whereas the N-terminal deletions ablated constitutive activity and decreased DA-induced activation, C-terminal deletions induced robust increases. These data, interpreted in concert with structural predictions generated from homology modeling implicate the central IL3 as playing an important role in the activation and subtype-specific characteristics of the D1-class receptors. This study may serve as a basis for the development of novel drugs targeting the central IL3 region.
Do you want size with that? The McMansion malaise

description: Australia has long prided itself on being an equal society, and for most of the 20th century our housing was a mirror of that value or belief. Almost all houses were single-storey detached and, with the exception of the Tooraks and Vaucluses, the dwellings of the affluent were not greatly larger than those of people on more moderate incomes. But in the last decade of the twentieth century a new housing product began to emerge: the very large two-storey dwellings now labelled McMansions. How has a dwelling form which cuts across all good principles of environmental sustainability come to dominate the growth suburbs of Australian cities? What does it say about us?
Investigation into development of deterioration curves and prediction models for concrete bridge decks in Ontario.

description: The deterioration of highway structures in Ontario due to the use of de-icing salts during winter maintenance operations has resulted in costly rehabilitations or replacements of structures in as little as 15 years after the time of construction. The Ministry of Transportation of Ontario presently has jurisdiction over approximately 3,200 of the bridges in Ontario. Approximately one third have been rehabilitated in the last decade. The approximate cost, of these rehabilitation projects varied from a high of $68 million in 1982 to a low of \$36 million in 1983 and $550 million in the last decade (amounts in 1990 dollars). This study can help the Ontario Ministry of Transportation make better decisions on the prioritization of bridge deck rehabilitations. The programs presently in place at the Ministry are effective in attempting to address the ever growing problem of deterioration of Ontario bridge decks. The Bridge Management Section has adopted a benefit/cost analysis to ensure that budgets for rehabilitating structures are effectively spent, as provincial funding for rehabilitations is not adequate to repair all deteriorated structures. Nevertheless, some method of prioritization must be utilized which considers both the level of deterioration of the bridge deck and the money available for rehabilitations.

description: Global health is an emerging concern in a rapidly changing world in which health issues transcend international borders. This study developed and validated a new self-report questionnaire to assess self-perceived global health competencies among international medical students and how they are influenced by international clinical experiences. A tool consisted of two scales and four subscales with moderate internal consistency. Comparisons between participants who completed retrospective pretest (after the intervention retrospectively) and those who completed traditional pretest (before the intervention) revealed that those participants who completed the questionnaires retrospectively provided lower pretest scores, suggesting that response-shift bias had occurred. Significant increases in scores after international clinical experience were reported for the majority of global health competency measures in IFMSA group. Linear regression identified participant’s age, gross national income (GNI) of country of medical studies, GNI of the country visited, duration of international clinical experience and years of medical school completed, as significant predictors of global health scores. This study contributes valuable information about the newly developed global health competencies measurement tool.

3D Vision for improved scene understanding in robotic surgery
Creators: name: Tukra, Samyakh
Publisher: name: Imperial College London
Year: 2023

description: Robotics and Mixed Reality (MR) visualisation are revolutionising Minimally Invasive Surgery (MIS), enhancing precision and efficiency. These technologies promise better patient outcomes, shorter recovery times, and reduced complications. A key application is guiding tumor resection, where MR can overlay tissue characteristics from intra- and pre-operative sensors as dynamic holograms on anatomical structures, enhancing the surgeon’s view. However, its clinical adoption has been slow due to challenges with real-time autonomy, robustness against moving objects, and soft-tissue deformation. Addressing these issues requires accurate, occlusion-aware, geometrically and temporally consistent depth estimation in complex, dynamic environments. In this thesis, I tackle four key challenges: (1) occlusions causing ambiguous depth, (2) sub-millimeter depth accuracy, (3) dynamic motion, and (4) temporal inconsistency. I propose Deep Learning (DL) solutions focused on self-supervised learning and generative modeling, circumventing the need for scarce ground truth data in surgery. First, I developed a bespoke video generative model that removes occlusions from a video and generates new frames with high spatial fidelity. To enhance depth estimation accuracy, I designed a multi-scale perceptual loss function that achieves State-of-the-Art performance even with a randomly connected neural network, surpassing many stereo models. I further adapted this approach to a stereo depth estimation model that achieves sub-millimeter accuracy without surgical training data. For dynamic motion and temporal consistency, I introduced a novel method that trains two models: (i) a Multi-Layer Perceptron (MLP) for 3D scene-flow prediction and (ii) a video depth estimation model that learns temporal dynamics via Diffusion. These models optimise each other to ensure temporal consistency in depth estimation, even in highly dynamic environments. Finally, I present an MLOps pipeline for deploying DL models on MR hardware, such as the Microsoft HoloLens, via the Cloud for clinical use.

description: This dissertation on American imperialism toward Côte d’Ivoire challenges mainstream theories in International Relations. It argues that in order to understand imperialism, we must understand the ontology of the power at work and of states mediating the global capitalism and the historical context. Following Robert Cox’s and Alejandro Colás’ works, it suggests broadening our comprehension by reconnecting imperialism to empire. The framework reveals that imperialism is not just naked brigandage, nor selfish expansion of culture or power. The thesis argues an imperial market security politics historically engaged into the restoration of the modern sovereignty of failed states and regulation of their regime, economy and culture. Through a historical study of the American case in Côte d’Ivoire, the dissertation finds that its dominion of the structures of security, knowledge and market makes the United States of America an empire attuned to the postcolonie era with authority to dictate the rules of the game. It also finds that Côte d’Ivoire is a failed state. American led-globalization runs up against the colonial pact which makes France the owner. Subverting modern capitalism, contestations against the democratic transition regime and France supporting the statu quo ante crush down into civil war and the disruption of Côte d’Ivoire’s sovereignty in an age of terror. The United States' Government implements Peace and security, Investing in People, Governing Justly and Democratically and People-to-People. It also dictates the agenda to restore Côte d’Ivoire’s sovereignty: electoral legitimacy of rulers and constitutional breakthrough. These global programs and agenda spread out in Côte d’Ivoire, public goods historically fostered by empires: the condition of stability, legitimate authority, and sense of belonging.

description: This paper seeks to investigate the link between the objective regional opportunity structure (captured by regional data) and individuals’ engagement in different stages in the venture creation process (intention to start a business and engagement in nascent entrepreneurship). We further investigate pathways through which a favourable regional environment could affect entrepreneurial intentions and the propensity to be a nascent entrepreneur. We combine individual level GEM-data for Western Germany with regional level data from the statistical office and use multi-level analysis to test our hypotheses. We find support for our contention that a favourable regional opportunity structure affects entrepreneurial intentions and engagement. As pathways between the region and individual behaviour serve the individual perception of founding opportunities and the individual social capital.

description: An extensive body of educational literature examines the process and implications of how an individual becomes a teacher, but studies within this field often minimize or ignore the existential nature of this act of becoming. Something happens to the individual as they enter into the teaching profession and commence their teaching practice and in many educational jurisdictions, those happenings are left for the novice teacher to grapple with in isolation. This study presents interpretations of four teacher candidates’ sense of becoming and provides a meta-analysis of important existential themes arising from examinations of the participants’ professional self-understanding. This study engages with the concept of existential becoming in teacher candidates through a hermeneutic phenomenological approach to interpretation and understanding. Four teacher candidates, about to enter their final teaching practicum before graduating from an eight-month Bachelor of Education program as certified teachers, participated in this research project which included one-on-one interviews, journal analysis and focus groups. Interpretations of these teacher candidates’ understandings of becoming a teacher are organized by Kelchtermans’ professional self-understanding framework and presented through the use of poetic vignettes and images of the teacher candidates’ paths of becoming. These aesthetic representations of teacher candidates’ understandings of becoming offer an alternative and existentially-informed vehicle for teacher candidate reflection and professional self-understanding. Data analysis and hermeneutic interpretations among and between the researcher and the participants revealed a number of existential themes present in the teacher candidates’ understandings of becoming a teacher, including: fear, responsibility, authenticity, purpose, and the self. Each theme is examined via a connection to both existential and teacher education literature and implications for teacher education programs are discussed.
New Zealand rural small businesses and their entrepreneurial behaviour

description: This paper analyses data from the New Zealand Centre’s annual survey of a panel data set of 1500 New Zealand SMEs undertaken from 2007 to 2009 to examine the performance and strategies of small businesses in a rural location in New Zealand. In theory rural SMEs are at disadvantage when compared to small business in urban locations in their abilities to react to changing economic conditions and undertaking investment in new product development and innovative activities such as new management and marketing activities. It has been well documented that rural SMEs, compared to urban SMEs, tend to be smaller in size, less likely to be classified as growth firms, have access to limited resources due to the leanness of the environment (as opposed to munificence of urban areas) and tend to be less innovative (e.g., Telford, 2006). It is arguable that in the case of rural SMEs in New Zealand such factors are compounded by remoteness of markets and greater ‘rurality’ of the environment. In this paper we compare theoretical explanations to results from the New Zealand Centre for SME Research (NZSMERC) annual mail survey of New Zealand’s SMEs, the BusinesSMEasure. We examine the strategies of rural small business owners in the face of changing economic conditions and how they have responded over time from 2007 to 2009. Comparisons are made in the annual surveys with firms from urban locations. We report initial findings that suggest that firms in rural locations have to be at least as innovative as their urban counterparts as the recession deepened in 2009. We discuss the entrepreneurial behaviour of rural SMEs in New Zealand as demonstrated over time in the light of theoretical expectations, their strategies and their level of innovative activities.

description: Iron oxyhydroxides are ubiquitous in surface environments, playing a key role in many biogeochemical processes. Their characterization is made challenging by their nanophase nature. Magnetometry serves as a sensitive non-destructive characterization technique that can elucidate intrinsic physical properties, taking advantage of the superparamagnetic behaviour that nanoparticles may exhibit. In this work, synthetic analogues of common iron oxyhydroxide minerals (ferrihydrite, goethite, lepidocrocite, schwertmannite and akaganéite) are characterized using DC and AC magnetometry (cryogenic, room temperature), along with complementary analyses from Mössbauer spectroscopy (cryogenic, room temperature), powder X-ray diffraction and scanning electron microscopy. It was found that all of the iron oxyhydroxide mineral nanoparticles, including lepidocrocite, schwertmannite and akaganéite were superparamagnetic and therefore magnetically ordered at room temperature. Previous estimates of Néel temperatures for these three minerals are relatively low and are understood as misinterpreted magnetic blocking temperatures. This has important implications in environmental geoscience due to this mineral group’s potential as magnetic remanence carriers. Analysis of the data enabled the extraction of the intrinsic physical parameters of the nanoparticles, including magnetic sizes. The study also showed the possible effect on these parameters of crystal-chemical variations, due to elemental structural incorporation, providing a nanoscale mineralogical characterization of these iron oxyhydroxides. The analysis of the intrinsic parameters showed that all of the iron oxyhydroxide mineral nanoparticles considered here have a common magnetic moment formation mechanism associated with a random spatial distribution of iv uncompensated magnetic spins, and with different degrees of structural disorder and compositional stoichiometry variability, which give rise to relatively large intrinsic magnetization values. The elucidation of the magnetic nanostructure also contributes to the study of the surface region of the nanoparticles, which affects the particles’ reactivity in the environment.

politique étrangère du Canada

description: Entre 1998 et 2002, le gouvernement du Canada a développé, adopté et déployé une stratégie triaxiale visant à prévenir toute exportation d’eau en vrac au pays, spécialement à destination des États-Unis. Cette politique étrangère étonne 1) de par son ampleur (modification de la loi de mise en œuvre du traité sur les eaux limitrophes partagées avec les États-Unis; négociation d’un accord intergouvernemental pancanadien touchant à un champ de compétence provincial; renvoi conjoint avec les États-Unis à la Commission mixte internationale); 2) de par son intransigeance (refus de principe de l’exportation d’eau en vrac plutôt qu’une évaluation des projets au cas par cas); et 3) de par son caractère préventif (refus par avance d’une industrie au potentiel de développement presque nul à court et moyen termes). En effet, un tel effort pour contrer l’exportation d’une ressource naturelle paraît a priori contraire à l’intérêt national d’un pays dont l’histoire économique est marquée par la vente massive de ses ressources à l’étranger. Afin de déterminer comment il a été possible pour le Canada de mettre en place une politique étrangère allant de prime abord si clairement à l’encontre de son intérêt national, la présente thèse propose de délaisser la conception classique de cet intérêt, exprimée en termes utilitaires et objectivistes, pour une conception plus récente, dite discursive, et exprimée en termes identitaires et intersubjectifs. Sur la base d’un exercice de raisonnement contrefactuel; de l’analyse sémantique du débat public concernant l’exportation d’eau en vrac; et de l’étude des représentations historiques de l’eau et de la relation Canada-États-Unis dans la société canadienne, cette avenue permet de soutenir que la stratégie anti-exportation d’eau en vrac du Canada s’inscrit en fin de compte bel et bien dans son intérêt national. C’est-à-dire qu’elle donne l’occasion au Canada de mettre de l’avant la protection d’une ressource unique, considérée comme un élément vital, un patrimoine national et une composante de l’identité canadienne, identité qu’il convient d’affirmer vis-à-vis de l’Autre états-unien en refusant que le Canada ne soit réduit, presque littéralement, au statut de porteur d’eau de son puissant voisin du sud.

description: The objective of this thesis is to analyze the kinematics of a mobile parallel robot with contribution that pertain to the singularity analysis, the optimization of geometric parameters and the optimal control to avoid singularities when navigating across singular geometric configurations. The analysis of the workspace and singularities is performed in a prescribed reference workspace regions using discretization method. Serial and parallel singularities are analytically analyzed and all possible singular configurations are presented. Kinematic conditioning index is used to determine the robot’s proximity to a singular configuration. A method for the determination of a continuous and singularity-free workspace is detailed. The geometric parameters of the system are optimized in various types of pipe-like structures with respect to a suitable singularity index, in order to avoid singularities during the navigation across elbows. The optimization problem is formulated with an objective to maximize the reachable workspace and minimize the singularities. The objective function is also subjected to constraints such as collision avoidance, singularity avoidance, workspace continuity and contact constraints imposed between the boundaries and the wheels of the robot. A parametric variation method is used as a technique to optimize the design parameters. The optimal design parameters found are normalized with respect to the width of the pipe-like structures and therefore the results are generalized to be used in the development phase of the robot. An optimal control to generate singularity-free trajectories when the robotic device has to cross a geometric singularity in a sharp 90◦ elbow is proposed. Such geometric singularity inherently leads to singularities in the Jacobian of the system, and therefore a modified device with augmented number of degrees of freedom is introduced to be able to generate non-singular trajectories.

description: Spectrum access protocols have been proposed recently to provide flexible and efficient use of the available bandwidth. Game theory has been applied to the analysis of the problem to determine the most effective allocation of the users’ power over the bandwidth. However, prior analysis has focussed on Shannon capacity as the utility function, even though it is known that real signals do not, in general, meet the Gaussian distribution assumptions of that metric. In a non-cooperative spectrum sharing environment, the Shannon capacity utility function results in a water-filling solution. In this thesis, the suitability of the water-filling solution is evaluated when using non-Gaussian signalling first in a frequency non-selective environment to focus on the resource allocation problem and its outcomes. It is then extended to a frequency selective environment to examine the proposed algorithm in a more realistic wireless environment. It is shown in both scenarios that more effective resource allocation can be achieved when the utility function takes into account the actual signal characteristics. Further, it is demonstrated that higher rates can be achieved with lower transmitted power, resulting in a smaller spectral footprint, which allows more efficient use of the spectrum overall. Finally, future spectrum management is discussed where the waveform adaptation is examined as an additional option to the well-known spectrum agility, rate and transmit power adaptation when performing spectrum sharing.

description: Some chemical compounds, especially alcohol, sugars, and alkaloids such as hordenine, have been reported as elicitors of different emotional responses. This preliminary study was based on six commercial beers selected according to their fermentation type, with two beers of each type (spontaneous, bottom, and top). Chemometry and sensory analysis were performed for all samples to determine relationships and patterns between chemical composition and emotional responses from consumers. The results showed that sweeter samples were associated with higher perceived liking by consumers and positive emotions, which corresponded to spontaneous fermentation beers. There was high correlation (R = 0.91; R2 = 0.83) between hordenine and alcohol content. Beers presenting higher concentrations of both, and higher bitterness, were related to negative emotions. Further studies should be conducted, giving more time for emotional response analysis between beer samples, and comparing alcoholic and non-alcoholic beers with similar styles, to separate the effects of alcohol and hordenine. This preliminary study was a first attempt to associate beer compounds with the emotional responses of consumers using non-invasive biometrics.

description: Perturbations to extravillous trophoblast (EVT) cell migration and invasion are associated with the development of placenta-mediated diseases. Dietary polyphenols have been shown to influence cell migration and invasion in models of tumorigenesis and non-cancerous, healthy cells; however, never shown in EVT cells. We hypothesize that polyphenols present in V. angustifolium leaves will promote trophoblast migration and invasion through ERK and AKT activation. Using the HTR-8/SVneo cell line as a model for EVT cells, the leaf extract increased trophoblast migration and invasion, in an ERK- and AKT-independent manner, and had no effect on cell proliferation or viability. One major polyphenol of the leaf extract was identified and may be an active compound. We have demonstrated for the first time that V. angustifolium leaf extract increases EVT migration and invasion in vitro, thus further investigations examining potential therapeutic applications of this extract in the context of placenta-mediated diseases are warranted.

description: Worldwide demand for energy is increasing rapidly, partly driven by dramatic economic growth in developing countries. This growth has sparked concerns over the finite availability of fossil fuels and the impact of their combustion on climate change. Consequently, many recent research efforts have been devoted to the development of renewable fuels and sustainable energy systems. Interest in liquid biofuels, such as ethanol, has been particularly high because these fuels fit into the conventional infrastructure for the transportation sector. Ethanol is a renewable fuel produced through the anaerobic fermentation of sugars obtained from biomass. However, the relatively high energy demand of its production process is a major factor limiting the usefulness of ethanol as a fuel. Due to the dilute nature of the fermentation product stream and the presence of the ethanol-water azeotrope, the separation processes currently used to recover anhydrous ethanol are particularly inefficient. In fact, the ethanol separation processes account for a large fraction of the total process energy demand. In the conventional ethanol separation process, ethanol is recovered using several distillation steps combined with a dehydration process. In this dissertation, a new hybrid pervaporation-distillation system, named Membrane Dephlegmation, was proposed and investigated for use in ethanol recovery. In this process, countercurrent vapour-liquid contacting is carried out on the surface of a pervaporation membrane, leading to a combination of distillation and pervaporation effects. It was intended that this new process would lead to improved economics and energy efficiency for the entire ethanol production process. The Membrane Dephlegmation process was investigated using both numerical and experimental techniques. Multiphase Computational Fluid Dynamics (CFD) was used to study vapour-liquid contacting behaviour in narrow channels and to estimate heat and mass transfer rates. Results from the CFD studies were incorporated into a simplified design model and the Membrane Dephlegmation process was studied numerically. The results indicated that the Membrane Dephlegmation process was more efficient than simple distillation and that the ethanol-water azeotrope could be broken. Subsequently, a pilot-scale experimental system was constructed using commercially available, hydrophilic NaA zeolite membranes. Results obtained from the experimental system confirmed the accuracy of the simulations.

description: Amifostine (WR-2721, delivered as Ethyol) is a radioprotector agent that reduces the likelihood of early and/or late biological effects by eliminating free radical particles during ionizing radiation fraction (radiotherapy). It activates in under normal tissues conditions to reduce mutation and fraction in DNA. Among 4000 prodrug compounds, amifostine is the only agent has been approved from the US Food and Drug Administration in clinical purposes. The main effective mechanisms of amifostine are based on scavenging for free radical, improving for DNA repair step and indication of cellular hypoxia. In the same time, this drug is not widely used around the world for different reasons mainly its high cost and toxicity level (lethal dose). Conjugating a monoclonal antibody with amifostine by a suitable linker is a process of Antibody Drug Conjugate producing immuno-radioprotector molecule hypothesis. Administrated molecule is an approach of targeted delivery therapy that increases the dosage uptake into particular area of treatment to minimize the dose distribution in non-targeted area in the body. In the present work, we proposed a three-compartment system model to simulate the two-pore theory pathway of an immuno-radioprotector molecule when it is crossing the physiological barriers. The model investigated its distribution and elimination in porous media (with both large and small pores) within a pharmacokinetics compartmented model approach.

description: The homeodomain transcription factor family of Cdx genes, Cdx1, Cdx2 and Cdx4, are known to play essential roles in many developmental processes including neural tube closure, axial elongation, hematopoiesis and gastrointestinal patterning. In the adult, Cdx1 and Cdx2 are both expressed strictly in the adult intestinal epithelium, but their functions and mechanisms of action at this stage are poorly understood. Cdx transcription factors have also been reported to be lost in intestinal cancers. To circumvent early lethality, a conditional loss of function strategy was used to inactivate Cdx2 in the adult intestinal epithelium. These conditional mutants were crossed to Cdx1-/- mice to examine potential functional compensation between these family members as well as into APC(min/+) mice to study their role in tumorigenesis. Using these models, I have found that Cdx2 regulates adult intestinal homeostasis and differentiation in the small intestinal epithelium, while both Cdx1 and Cdx2 contribute to colon homeostasis. Furthermore, Cdx transcription factors are tumor suppressors in the development of Wnt-induced colorectal cancer, and impact several pathways including TGF-β and Eph-ephrin signaling. Finally, Cdx2 regulates Eph-ephrin signaling through direct activation of the Notch pathway. Altogether, this study underscores critical roles and mechanisms of action for Cdx members in the adult intestine and in intestinal tumorigenesis.

description: L’objectif de cette étude est d’examiner l’expérience phénoménologique du personnel infirmier en psychiatrie faisant usage de la contention mécanique et ce, afin de repositionner cette perspective dans un discours éthique plus sensible à l’expérience vécue des soignants. Vingt-et-un(e) infirmier(e)s travaillant sur les unités de psychiatrie et d’urgence psychiatrique d’un centre hospitalier universitaire de l’Ontario ont participé à des entrevues semi-dirigées, qui ont ensuite été transcrites, codées et analysées selon la méthode d’analyse interprétative phénoménologique (AIP). Trois thèmes principaux ont été identifiés : 1) Contexte de pratique; 2) Processus de contention; et 3) Recourir à la contention mécanique. Ces résultats mettent en lumière les défis organisationnels et émotionnels auxquels font face les infirmier(e)s en psychiatrie. Les travaux de Foucault, Goffman, Beck et Festinger ont guidé le processus d’analyse critique, menant aux différentes implications de cette étude pour la pratique clinique, l’enseignement et la recherche infirmière.
