This study is intended to explore the interactive effect of various interpersonal groups and longitudinal maturation on the socialization of individuals within a culture. It will deal with conflict resolution and the formation of a transitory sense of self informed by George Herbert Mead's perspective with an emphasis on symbolic interaction. I have chosen as my sample group a division I female college soccer team in the eastern United States . My time as an assistant coach has given me access to the daily lives of these players for a two year period during which I have acted as a participant observer. Although the study is limited to a small group of elite athletes, it is presumed that similar processes are at work each time an individual enters a new social setting or attempts to reconcile conflicting norms between different groups. When such groups collide, the individual is forced to conform to one at the expense of the other(s). This creates what I will call deviant conformity / Master of Science

The purposes of this study were to determine if a kindergartener's developmental stage correlates with subsequent scholastic achievement, to determine whether developmentally younger children who repeat kindergarten attain higher academic achievement than developmental 1y younger children who do not repeat kindergarten, and to investigate the relationship between head circumference, developmental age, and achievement. Ninety-seven kindergartners of various ethnicity and socio-economic status were administered the Gesell School Readiness Screening Test to determine developmental age and were followed academically for three years. Head circumference was noted periodically to measure brain growth. The hypotheses predicted significant positive correlations between developmental age in kindergarten and scores on later achievement tests. Further, it was predicted that children below 5.3 years in developmental age who delayed entrance to first grade would score significantly higher on first grade achievement tests than match-paired promoted students. It was hypothesized that there would be significant correlations between head circumference growth and (a) gains in achievement test scores and (b) developmental age at kindergarten. The first hypothesis, tested by Pearson Product Moment Correlations, established the existence of significant correlations between developmental ages of test subjects and their scores on four academic achievement tests. The results indicated that developmental age was a better predictor of achievement test scores than chronological age. Since only five children in this study were retained in kindergarten, hypothesis 2 was analyzed descriptively. Mean scores on first grade achievement tests were higher for the retainees than for the "at risk" non-retainees. Hypothesis 3 was tested by stepwise multiple regression. At the first step, the linear trend between the independent variable, CTBS score, and the dependent variable, I TBS score, was calculated and found to be significant at the .001 level. The addition of head circumference growth to the equation did not add significantly to the prediction of I TBS scores from CTBS scores. There was a significant negative correlation between developmental age in kindergarten and head growth.

Au cours des prochaines années, il est prédit que le changement climatique va influencer la production des cultures et impacter négativement le secteur agricole. Parmi les cultures mondiales majeures, la vigne est cultivée pour ses baies, qui sont la base de produits à forte valeur ajoutée (vin, liqueurs, et métabolites secondaires utilisés dans les industries pharmaceutiques et cosmétologiques) et dont le métabolisme est fortement sensible au climat. Cependant, la réponse au niveau de la composition de la baie ainsi que les mécanismes moléculaires sous-jacents mettant en évidence la capacité de l’interaction porte-greffe/greffon à influencer le métabolisme de la baie dans des conditions de stress hydrique est encore très peu étudiée et compris. Dans ce contexte, cette thèse a eu pour objectifs de répondre à ces questionnements en combinant des approches ecophysiologique, biochimique et transcriptomique. Vitis vinifera cv. Pinot noir greffé soit sur le porte greffe 110R (tolérance à la sécheresse, vigueur conférée moyenne à forte) ou 125AA (sensible à la sécheresse, forte vigueur conférée) ont été étudié au cours de 3 années (2009, 2010 et 2011), au vignoble et dans des conditions témoin (pluviométrie normale) ou de stress hydrique provoqué. Différents paramètres physiologiques (statut hydrique et rendement) ainsi que le profil métabolique de la baie (sucres, acides organiques, acides aminés et anthocyanes) ont été caractérisés à quatre stades de développement (E-L 33, E-L 35, E-L 36, E-L 38). D’autre part, une analyse microarray sur génome complet a également été réalisée pour deux années (2009 et 2010) et deux stades de développement critiques et représentatifs (E-L 35 et E-L 36). Dans son ensemble, cette thèse fournit des nouveaux éléments concernant la réponse métabolique de la baie au porte-greffe et à la contrainte hydrique, et met en évidence des possibles mécanismes moléculaires impliqués dans cette réponse. / Climate change is expected to influence crop production and to impact negatively the agricultural sector in the future. Among the major crops cultivated worldwide, grapevine provides berries that are the basis of high added value products (wines, liquors, and secondary metabolites used in the pharmaceutical and cosmetological industry) and whose metabolism is strongly sensitive to climate (vintage effect). However, the response of berry composition and the molecular mechanisms underlying the ability of rootstock/scion interaction to influence grape berry metabolism under drought stress are still poorly understood. In this context, this work aimed to fill the gaps on the aforementioned questions by combining comprehensive ecophysiological measurements, detailed metabolite analysis, and whole-genome transcriptome analysis. Vitis vinifera cv. Pinot noir grafted on either rootstock 110R (drought tolerant, mid- to high vigor) or 125AA (drought sensitive, high vigor) were studied during three growing seasons (2009, 2010, and 2011) in the field under normal rainfall or water shortage conditions. We characterized different physiological parameters (water status and yield components) and berry metabolomic profiles (sugars, organic acids, free amino acids and anthocyanins) during four developmental stages (E-L 33, E-L 35, E-L 36, E-L 38). Besides we also performed a microarray analysis in two years (2009 and 2010) at two critical and representative developmental stages (E-L 35 and E-L 36). Overall, this work provides novel insights into the response of grape berry metabolites to rootstock and to drought and uncovers some possible molecular mechanisms underlying the berry response to different rootstock/water status combinations.

Background: Over the years, businesses have come under the microscope as consumers and other stakeholders such as employees, environmentalist and journalists investigate any wrongdoings. Investors are also aware of the damages caused by organizations that are only concerned with profit maximization, and now they are diverging their investment to more sustainable companies. To overcome internal and external pressure, companies are accepting the responsibilities they have towards the society, environment, and shareholders. However, the journey of becoming responsible and environmentally sustainable is long and it often requires organizational change. Corporate Social Responsibility (CSR) is now known to most public and private firms. Over the decades, scholars have come up with various definitions for CSR which are often complex and diverse. Therefore, there is a need to understand how companies implement CSR rather than if they should implement it (Smith, 2003). The conceptualization of CSR, understanding what motivates towards CSR and how it is implemented within the organizations has attracted the attention of scholars (Maon, Lindgreen, & Swaen, 2010) Purpose: The purpose of this paper is to assess organisations journey to become sustainable companies using a developmental stage model, in this case the Consolidative model and to find empirical support the usefulness of this model as an assessment tool. Method: To achieve the purpose of this study, a qualitative method along with an abductive approach is used. Eight semi-structured interviews are used for collecting primary data while peer-reviewed articles and books are used to build the theoretical framework. Conclusion: Empirical findings support that the consolidative mode is useful in assessing the sustainability journey of organizations. No organization is found to be in the first three stages that are the dismissing, self-protecting, and compliance seeking stages. Pressure from stakeholders, personal values, beliefs and the desire to be competitive are what motivates organizations to work with CSR despite their small size.
