Strategies designed to improve educational systems have created tensions in school personnel as they struggle to respond to competing demands of ongoing change within their daily realities. The purpose of this case study was to investigate how teachers and administrators in one elementary school made sense ofthese tensions and to explore the factors that constrained or shaped their responses. A constructive interpretative case study using a grounded theory approach was used. Qualitative data were collected through document analysis, semi-structured interviews, and participant observation. In-depth information about teachers' and administrators' experiences and a contextual understanding oftension was generated from inductive analysis of the data. The study found that tension was a phenomenon situated in the context in which it arose. A contextual understanding of tension revealed the interactions between the institutional, personal, and emotional domains that continually shaped individual and group behavioural responses. This contextual understanding of tension provided the means to reinterpret resistance to change. It also helped to show how teachers and administrators reconstructed identities and made sense in context.. Of particular note was the crucial nature of the conditions under which teachers and adlninistrators shaped meaning and understood change. This study sheds light on the contextual intricacies of tension that may help leaders with the complex design and implementation of educational change..

The 19th Century Tombstone Database project was funded by the program Federal Summer Youth Employment scheme in the summer of 1982 and led by Dr. David W. Rupp, a Professor at the Classics Department, Brock University. The main goal of the project was to collect information related to various cemeteries in Niagara region and burials that took place from 1790-1890. Data was collected and presented in the form of data summary forms of persons, tombstone sketches, photographs of tombstones, maps, and computer printouts. The materials created as a result of a research completed for the 19th Century Tombstone Database project are important as a number of the tombstones have been damaged or gone missing since the research was finished. Before Dr. Rupp retired from Brock University, he donated project materials to the Brock University Special Collections and Archives.

Traditional employment options for persons with developmental disabilities are lacking. Employment options available for persons with developmental disabilities are reflective of the medical and social model perspectives of disability; with segregated and supported employment reinforcing the idea that persons with developmental disabilities are incapable and competitive employment missing the necessary accommodations for persons to be successful. This study examined social enterprises as an alternative employment option that can balance both medical and social model perspectives by accommodating for weaknesses or limitations and recognizing the strengths and capabilities of persons with developmental disabilities in the workplace. Moreover, this study is part of a broader case study which is examining the nature and impacts of a social enterprise, known as Common Ground Co-operative (CGC), which supports five social purpose businesses that are owned and operated by persons with developmental disabilities. This study is part of the Social Business and Marginalized Social Groups Community-University Research Alliance. To date, a case study has been written describing the nature and impacts of CGC and its related businesses from the perspectives of the Partners, board members, funders and staff (Owen, Readhead, Bishop, Hope & Campbell, in press & Readhead, 2012). The current study used a descriptive case study approach to provide a detailed account of the perceptions and opinions of CGC staff members who support each of the Partners in the five related businesses. Staff members were chosen for the focus of this study because of the integral role that they play in the successful outcomes of the persons they support. This study was conducted in two phases. In the first phase five staff members were interviewed. During this stage of interviews, several themes were presented which needed to be examined in further detail, specifically staff stress and burnout and duty of care for business Partners versus the promotion of their autonomy. A second phase of interviews was then conducted with one individual participant and a focus group of seven. During both interview phases, Staff participants described an employment model that creates a non-judgemental environment for the business Partners that promotes their strengths, accommodates for their limitations, provides educational opportunities and places the responsibility for the businesses on the persons with developmental disabilities cultivating equality and promoting independence. Staff described the nature of their role including risk factors for stress, the protective factors that buffer stress, and the challenges associated with balancing many role demands. Issues related to the replication of this social enterprise model are described.

La tumeur des cellules de la granulosa (GCT) représente 5% des cas de cancers ovariens chez la femme. Bien que considérées comme peu malignes, la mort survient dans 80% des cas suite à une recrudescence de la maladie. En dépit de ces statistiques sinistres, peu d’études ont été portées sur ce type de cancer. Le premier objectif de cette étude consistait à élucider les mécanismes moléculaires causant les GCT en démontrant l’implication de la voie de signalisation PI3K/AKT dans leur étiologie. Pour ce faire, nous avons employé la technologie Cre-Lox afin de cibler le gène Pten (antagoniste de cette voie) spécifiquement dans les cellules de la granulosa chez la souris. Ces souris (Ptenflox/flox;Amhr2cre/+) ont occasionnellement développé des GCT, soutenant notre hypothèse de l’importance de la voie PI3K/AKT dans leur étiologie. La voie WNT/CTNNB1 est une autre voie de signalisation qui a récemment été impliquée dans le développement des GCT. Dans le cadre de ce projet, nous avons également testé l’existence possible d’une synergie fonctionnelle entre les voies WNT/CTNNB1 et PI3K/AKT dans le développement de la maladie. Pour ce faire, nous avons créé le modèle transgénique Ptenflox/flox;Ctnnb1flox(ex3)/+;Amhr2cre/+, chez lequel les cellules de la granulosa présentant non seulement une désinhibition de la voie PI3K/AKT, mais aussi une suractivation de la voie WNT/CTNNB1. Tel que prédit, les souris Ptenflox/flox;Ctnnb1flox(ex3)/+;Amhr2cre/+ ont développé une forme de GCT beaucoup plus agressive que celle observée chez les femelles Ptenflox/flox;Amhr2cre/+. Spécifiquement, le développement des tumeurs se déclenchait plus tôt, leur croissance était beaucoup plus rapide, nous avons pu observer des métastases pulmonaires et la dissémination des cellules tumorales dans la cavité péritonéale, et la maladie était invariablement fatale avant l’âge de 8 semaines. Le modèle Ptenflox/flox;Ctnnb1flox (ex3)/+;Amhr2cre/+ a donc servi à démontrer l'existence d'une synergie entre les voies WNT/CTNNB1 et PI3K/AKT dans le développement de la GCT. De façon inattendue, les souris Ptenflox/flox;Amhr2cre/+ ont aussi présenté un phénotype de sous-fertilité qui n’était pas d’origine ovarienne. Il a récemment été démontré que la souche Amhr2cre dirige l’expression de Cre non seulement aux cellules de la granulosa, mais aussi au stroma utérin et au myomètre. Le second objectif de ce travail était donc de démontrer si et comment le phénotype d’infertilité chez les souris Ptenflox/flox;Amhr2cre/+ pouvait découler d’un défaut utérin. Lors de l'implantation, les cellules du stroma utérin se différencient en cellules déciduelles pour former la décidua maternelle (DM), qui se régresse ensuite par apoptose afin de faciliter l’invasion des cellules trophoblastiques. De plus, la DM, en collaboration avec le tissu foetal, recrute des uNKs dont le rôle est de remodeler les artères spiralées pour augmenter l’apport sanguin maternel vers le foetus en développement. Nous avons pu démontrer que l'utérus des femelles gestantes Ptenflox/flox;Amhr2cre/+ présentait une DM anormalement résistante à l'apoptose, moins de uNKs et des artères spiralées non-remodelées. Par conséquent, l’invasion des cellules du trophoblaste était restreinte, compromettant le développement et la survie de l'embryon. Nous avons donc établi pour la première fois l’importance de Pten lors de la décidualisation et de l’invasion du trophoblaste.
