This study has found that youth who or whose parents had left their home country for fear-based reasons were less involved within their school and wider community than youth who left or whose parents left for reasons concerning their social mobility. Many existing studies focus on the challenges newcomer youth experience within the education system (see Anisef, Brown, Phythian, & Sweet, 2010), however through the use of qualitative methodologies this study expanded on the current literature by further examining why it is some youth are successful in overcoming such challenges, while others are not. This study supported what has been demonstrated in the literature regarding challenges faced by newcomer youth and resources to address such challenges. Despite challenges experienced within the education system, youth planned to complete secondary school and attend a postsecondary institution. However, not all youth anticipated remaining in Canada upon completion of their education, with youth or youth whose parents left their home country for fear-based reasons frequently discussing the possibility of returning to their or their parents' home country. Thus, perhaps these youth were less involved within their school, as their goal was not necessarily to establish or maintain connections within their community as they may have viewed residing in Canada as temporary. This finding has important implications, as there are benefits to involvement in extracurricular activities, which may assist youth in overcoming challenges encountered within the education system. Therefore, it would seem that youth who had or whose parents had left their home country for reasons concerning their social mobility may have be at an advantage within the education system with respect to their involvement in school. Perhaps then this differential involvement may at least partially explain why it is some newcomer youth are able to overcome challenges they experience in the education system, while others are not. Both policy and theoretical implications are discussed.

This study used a life history research design to explore first-generation university students' educational life stories and experiences with cultural capital. The project sought to examine how 3 first-generation university students experience cultural capital that is privileged in Ontario's education system and how the interactions between capital acquired through experiences within the home and school and capital privileged by the education system affect these students' educational experiences and perceptions. Using Pierre Bourdieu's (1984; 1986) theory of cultural capital as a framework, 3 firstgeneration, first-year university students participated in two 1- to 2-hour interviews. A focus on each participant's experiences with culture, capital, and education revealed themes corresponding to navigating, utilizing, and confronting familial, institutional, economic, and embodied forms of cultural capital. The study highlights the importance of recognizing how cultural capital influences the education system and how firstgeneration students can recreate normative pathways and achieve academic success despite challenges posed by the cultural capital privileged within the education system. Given cultural capital's effect on academic success, understanding first-generation students' educational life stories sheds light on the complex challenges facing students who confront and deal with privileged culture in the education system.

This study explores the stories and experiences of second-generation Portuguese Canadian secondary school students in Southern Ontario, Canada. The purpose of this research was to understand the educational experiences of students, specifically the successes, challenges, and struggles that the participants faced within the education system. Questions were also asked about identity issues and how participants perceived their identities influencing their educational experiences. Six Portuguese Canadian students in grades 9 to 11 were interviewed twice. The interviews ranged from 45 minutes to 90 minutes in length. Data analysis of qualitative, open-ended interviews, research journals, field notes and curricular documents yielded understandings about the participants' experiences and challenges in the education system. Eight themes emerged from data that explored the realities of everyday life for second-generatiop Portuguese Canadian students. These themes include: influences of part-time work on schooling, parental involvement, the teacher is key, challenges and barriers, the importance of peers, Portuguese Canadian identity, lack of focus on identity in curricul:um content, and the dropout problem. Recommendations in this study include the need for more community-based programs to assist students. Furthermore, teachers are encouraged to utilize strategies and curriculum resources that engage learners and integrate their histories and identities. Educators are encouraged to question power dynamics both inside and outside the school system. There is also a need for further research with Portuguese Canadian students who are struggling in the education system as well as an examination of the number of hours that students work.

This project focuses on the bullying found in the 21st century elementary classrooms, more specifically in grades 4-8. These grades were found to have high levels of bullying because of major shifts in a student’s life that may place a student of this age at risk for problems with their peer relationships (Totura et al., 2009). Supporting the findings in the literature review, this handbook was created for Ontario grade 4-8 classroom teachers. The resource educates teachers on current knowledge of classroom bullying, and provides them with information and resources to share with their students so that they can create a culture of upstanders. Upstanders are students who stand up for the victims of bullying, and have the self-esteem and strategies to stand up to classroom bullies. These upstanders, with the support of their classroom teachers and their peers, will be a force strong enough to build the government-mandated Safe School environment.

This qualitative research project uses a Deleuzo-Guattarian theoretical framework to address the question: “How are the politically oriented social forums in Gaia Online experienced as a continuum of overlapping of lines, including molar lines, lines of flight, and molecular lines?” Although smooth lines of flight may occur in Gaia, there are always mechanisms that work to re-territorialize them as more striated molar operations. Conversely, while more striated molar lines may be evident in Gaia, there are also smooth lines of flight that attempt to deterritorialize them as smooth space. Founded in 2003, Gaia is a virtual community in which members use 3D avatars to socialize with others, create content, and play games. Deleuze and Guattari (1987) have defined space with three systems: on one end is state-oriented static space, on the other end is nomadic fluid space, and situated in the middle is molecular space which contains both smooth and striating elements. While state-oriented striated space is based on routines, rules, and specifications, nomadic smooth space is flexible, always changing, and full of possibility. Some of the smoother operations that are evident in Gaia include becoming other, decentred communications, desire as resistance, and lines of flight. Some of the more striated operations include social reproduction of gender norms/expectations, capitalist mechanisms, violence and intolerance linked to categories and binaries (racism/sexism/ageism), the regulation of desire, and the organisation of bodies.

This qualitative, phenomenological study investigated first generation students’ perceptions of the challenges they experienced in the process of accessing higher education and the type of school-based support that was received. Particular emphasis was placed on the impact of parental education level on access to postsecondary education (PSE) and how differences in support at the primary and secondary levels of schooling influenced access. Purposeful, homogenous sampling was used to select 6 first generation students attending a postsecondary institution located in Ontario. Analysis of the data revealed that several interrelated factors impact first generation students’ access to postsecondary education. These include familial experiences and expectations, school streaming practices, secondary school teachers’ and guidance counselors’ representations of postsecondary education, and the nature of school-based support that participants received. The implications for theory, research, and practice are discussed and recommendations for enhancing school-based support to ensure equitable access to postsecondary education for first generation students are provided.

RÉSUMÉ L’étiologie de la schizophrénie est complexe et le modèle de vulnérabilité-stress (Nuechterlein & Dawson, 1984) propose que des facteurs de vulnérabilité d’ordre génétique combinés à une histoire environnementale de stress particulier pousseraient l’individu vers un état clinique de psychose. L’objectif principal de cette thèse est de mieux comprendre la réaction physiologique des personnes schizophrènes face à un stress psychologique, tout en conceptualisant les symptômes psychotiques comme faisant partie d’un continuum, plutôt que de les restreindre sur un plan catégoriel. Afin de faire la différence entre les patients schizophrènes et les individus de la population générale, au-delà de la sévérité de leurs symptômes psychotiques, leur réaction au stress est comparée et le phénomène de seuil critique dans la réaction de cortisol est exploré en tant que point décisif pouvant distinguer entre les deux groupes. La première étude de cette thèse (Brenner et al., 2007) examine la fiabilité, la validité et la structure factorielle du Community Assessment of Psychic Experiences (CAPE) (Stefanis et al., 2002), avec un échantillon francophone et anglophone de la population nord américaine, un questionnaire auto-administré de 42 items qui évalue les expériences quasi-psychotiques présentes dans la population générale : des symptômes positifs (ou psychotiques), négatifs (ou végétatifs) et dépressifs. Ce questionnaire a été complété par un échantillon de 2 275 personnes de la population montréalaise. Les résultats appuient la consistance interne des 3 sous-échelles originales. De plus, l’analyse factorielle exploratoire suggère des solutions de 3-5 facteurs, où les solutions à 4 et 5 facteurs proposent de séparer les symptômes positifs en sous-catégories plus spécifiques. Finalement, cette étude suggère une version plus courte du CAPE, avec seulement 23 items, tout en préservant les mêmes trois échelles originales. La toile de fond de cet article confirme l’existence du phénomène du continuum de la psychose, où une variation de symptômes psychotiques peut se retrouver aussi bien dans la population générale que dans la population clinique. Dans une deuxième étude (Brenner et al., 2009), cette thèse examine à quel point la réponse de l’hormone de stress, le cortisol, à un test de stress psychosocial nommé le Trier Social Stress Test (TSST) (Kirschbaum, Pirke, & Hellhammer, 1993), peut établir une différence entre les sujets témoins et les patients schizophrènes, tout en contrôlant des variables importantes. Un groupe de 30 personnes schizophrènes et un groupe de 30 sujets de la population générale, recrutés lors de la première étude de cette thèse, ont participé à cette recherche qui est construite selon un plan expérimental. Le groupe témoin inclut des personnes légèrement symptomatiques et un chevauchement des scores psychotiques existe entre les deux groupes. Suite au stresseur, les deux groupes démontrent une augmentation significative de leur rythme cardiaque et de leur pression artérielle. Cependant, leur réponse de cortisol a tendance à différer : les patients schizophrènes présentent une réponse de cortisol plus petite que celle des témoins, mais en atteignant un seuil statistique significatif seulement à la mesure qui suit immédiatement le stresseur. Ces résultats significatifs sont obtenus en contrôlant pour la sévérité des symptômes positifs, un facteur discriminant significatif entre les deux groupes. Ainsi, le niveau de cortisol mesuré immédiatement après le stresseur se révèle être un marqueur de seuil critique pouvant établir une distinction entre les deux groupes. Aussi, leur réponse de cortisol maximale a tendance à apparaître plus tard que chez les sujets témoins. De façon générale, la réaction au stress des deux groupes étudiés est un autre moyen d’observer la continuité d’un comportement présent chez les individus, jusqu’à ce qu’un seuil critique soit atteint. Ainsi, il est possible de trancher, à un moment donné, entre psychose clinique ou absence de diagnostic.

Le présent mémoire décrit la synthèse et l’utilité de complexes Cu-NHC. En premier lieu, la synthèse de complexes de cuivre porteurs de ligand(s) de type carbène-N-hétérocyclique (NHC) via une génération décarboxylative de carbènes sera présentée. En effet, de précédents rapports font état de l’utilisation de carboxylates d’imidazol(in)ium en tant que précurseurs carbéniques sous conditions thermolytiques. Ainsi, la présente étude montre l’utilisation de ces espèces zwitterioniques pour la synthèse de complexes de cuivre(I) mono- et bis-NHC comportant divers substituants et contre-ions. Une seconde partie du projet se concentrera sur l’évaluation de complexes Cu-NHC en tant que catalyseurs pour la synthèse de 2,2’-binaphtols via une réaction de couplage oxydatif de naphtols. L’objectif de ce projet de recherche est d’étudier les effets de variations structurales de différents complexes Cu-NHC afin de construire un processus catalytique plus efficace. Les effets de la structure du catalyseur sur la réaction de couplage ont été évalués en variant son contre-ion, le nombre de ligands NHC se coordonnant au cuivre, ainsi que la nature des substituants du ligand.
