Notre recherche porte sur l'apprentissage des compétences professionnelles par de jeunes enseignants ontariens en insertion professionnelle. Elle vise à améliorer l'encadrement de la formation professionnelle des enseignants novices. Nous voulons répondre à la question suivante: comment l'accompagnement dans le cadre du mentorat conduit les jeunes enseignants à développer les savoir-faire professionnels? L'étude s'est déroulée dans le cadre du programme d'insertion professionnelle des nouveaux enseignants (PIPNE) en Ontario. Nous avons mené des entretiens auprès d'une vingtaine d'enseignantes et enseignants débutants et de seize mentors, qui exercent dans huit écoles secondaires de langue française de l'Ontario du Nord, de l'Est, du Centre-Sud et du sud-ouest de la province. Notre schéma pour les entretiens visait à connaître les thèmes de conversation entre mentors et mentorés. En fait, nous cherchions à savoir quels étaient les problèmes soulevés par les mentorés et les réponses données par les mentors. Les données d'entretiens révèlent que lorsque l'accompagnement dans le cadre du mentorat n'est pas systématiquement planifié, c'est-à-dire que des thèmes de perfectionnement professionnel spécifique ne sont pas suggérés par la direction de l'école et/ou le mentor, alors ce sont surtout des discussions sur le fonctionnement de la communauté professionnelle de l'école qui sont objet de discussion. Ces discussions socialisent l'enseignement débutant à la culture professionnelle de l'enseignant et participent à la construction de son identité professionnelle. En revanche, lorsque les discussions portent sur le perfectionnement des interventions pédagogiques, alors le mentoré construit les connaissances qui lui permettent d'apprendre à développer l'expertise professionnelle en enseignement. Aussi, nous nous sommes rendu compte de la valeur de l'implication des directions d'écoles dans le mentorat. Par ailleurs, nos données montrent que les mentors qui ont reçu une formation sont plus aptes à assumer leur rôle.

Since the 1980s microbreweries in Ontario have gained in popularity, winning over beer drinkers in the province and earning the support of the provincial government that funds the expansion of this creative industry. The Emergence of Ontario Microbreweries, adopting the theoretical perspectives of Margaret Archer and Michel Foucault, looks at the factors explaining the emergence of the craft beer industry. Through the morphogenetic approach, which sees enablements take shape through entrepreneurial pursuits, and disenablements through Foucauldian disciplinary processes, we observe that Ontario microbreweries were constrained by strict government laws. Enforced by the Liquor Control Board of Ontario (LCBO), these laws acted upon the individuals and their ability to consume alcohol both privately and publicly. Over time, the strict governmental regimes which constrained beer drinkers and micro-brewed beer producers gradually transformed to allow for the expansion of microbreweries that create unique, distinct and authentic products that have specific geographic links to community.

The herbicide, Dacthal (dimethyl 2,3,5,6,-tetrachloroterephthalate) is hydrolyzed to give the corresponding diacid and this derivative is a common contaminant in ground water. In the Ontario region of eastern Oregon the use of this herbicide on onions has resulted in the contamination of an aquifer with this derivative. Since movement to groundwater is determined by the hydrolysis of the parent compound to a more soluble derivative. The rate at which this hydrolysis reaction occurs and the stability of the metabolite must be defined. These parameters have been determined using soils from Ontario in which onions had been raised. At room temperature and 50% field capacity, the parent was hydrolyzed rapidly (half-life 16 days) to the diacid derivative. An increase of the incubation temperature to 38°C reduced the hydrolysis rate significantly (half-life 86.8 days). It is assumed that this response reflects reduced microbial activity at the higher temperature. At both temperatures only small amounts of the monoacid intermediate were detected suggesting that the Dacthal monoacid was being hydrolyzed at a faster rate than the parent. It was established that at room temperature, the half-life of the monoacid was only 2.8 days. Over the 300 days the experiments were carried out, little if any degradation of the diacid metabolite could be detected. There was virtually no degradation of the parent over a 60 day period in sterilized soil, suggesting that microbial activity is primarily responsible for this step. By contract, the monoacid was hydrolyzed at comparable rates in sterilized and nonsterilized soil. This study explains why the Dacthal metabolite is a common contaminant in groundwater. The parent is rapidly hydrolyzed to the diacid which is much more water soluble. More important, however, is the persistence of the diacid metabolite in the environment. / Graduation date: 1992

In this work, snow data, collected at the Centre for Atmospheric Research Experiments (CARE) site during the winter of 2005/06 as part of the Canadian CALIPSO/CloudSat Validation Project (C3VP) were analyzed with various goals in mind: 1) investigate the effects of surface temperature and system depth on the snow fall velocity and particle size distribution, 2) find the variables that control the relationships between snow fall velocity and size (control variables), 3) retrieve the coefficient and the exponent in the power-law mass-size relations used in snow reflectivity, 4) estimate vertical air motion and 5) describe the shape of snowflakes that can be used in polarimetric studies of snow. It also includes considerable calibration work on the Hydrometeor Velocity and Shape Detector (HVSD); as well as sensitivity testing for radar calibration and Mie-scattering effect on snow density. / Snow events were classified into several categories according to the radar echo vertical extent (H), surface and echo top temperatures (T s, Tt), to find their effects on snow fall velocity and particle size distribution. Several case studies, including situations of strong turbulence, were also examined. / Simple and multiple correlation analyses between control variables and parameters of the power-law size-velocity relationship were carried out for 13 snow cases having a high R2 between their mean snowflakes fall velocity and the v-D fitted curve, in order to find the control variables of power-law v-D relations. Those cases were all characterized by single layered precipitation with different echo depth, surface and echo top temperatures. Results show that the exponent "b" in v-D power-law relationship has little effect on the variability of snow fall velocity; all control variables (T s, Tt, H) correlate much better to the coefficient "a" than to the exponent "b", leading to a snow fall velocity that can be simulated with a varying coefficient "a" and a fixed exponent "b" (v=aD0.15) with good accuracy. Coefficient "a" and exponent "b" for a generic snow v-D relationship were also examined. The results indicate that coefficient "a" of generic snow represents the most frequent coefficient "a" during the events, while the exponent "b" does not show any representative. / Retrieval of the coefficient "a" and exponent "b" in a power-law mass-size relation, which eventually affects the snow reflectivity, was conducted by minimizing the root mean square (RMS) of differences in reflectivity between Vertically pointing McGill X-band Radar (VertiX) and HVSD. Minima of reflectivity differences lay on a diagonal direction of a diagram of the coefficient "a" (x-axis) versus exponent "b" (y-axis). It is shown that as the system deepens, the slope gets less steep. In addition, coefficient and exponent for this mass-size relation change with time, and snow density derived from several combined snow events does not explain the average snow density of the period. / A method to retrieve vertical air motion with good accuracy using VertiX and HVSD is suggested. Several snow shape parameters and relations between the area ratio (Ar) and size of snowflakes (Ar-D relation) are investigated with snow dimensions defined in various ways. These Ar-D relations will be used as a guideline in snow density models.

This thesis is an investigation into the frames and implicit concepts that drive the current trend of corporate-led agriculture, now known as the Third Food Regime. I consider whether this neoliberal regime is hegemonic in rural Ontario, that is, whether the dominant ideology of the corporate ruling class is reflected in and perpetuated by our farmers, despite it being against their best interests. I employ a critical approach, using mixed methods – participant observation of general farm organizations, content analysis of the farm media in Ontario and in-depth interviews with farmers in Wellington County – and find strong evidence of a free market frame in rural Ontario. This thesis outlines the dimensions and dangers of the existing frame in hopes that alternative agricultural models can again be considered. / SSHRC

This thesis stems from a general interest in press coverage of culture industries and products and the ways in which it links them to contemporary social and political concerns. The present project specifically takes The Globe and The Toronto World, two of the major daily newspapers of Toronto, as its combined object of analysis. It selects particular events and periods during the emergence of early film as popular amusement as the contexts for the study of articles, reports, columns, and editorials that centred around urban cultural issues as well as cinema. It explores the extent to which these particular events and periods figured in the papers' attention upon the new medium and its place in the everyday life of the city. These contexts were selected with an assumption of their newsworthiness for the daily press. However, upon examination it became evident that, while the majority of them did produce a concentrated attention in both dailies, not all of them did. Still, because they instantiated profound shifts in urban entertainment at the turn of the century, they were kept as historical backgrounds for the analysis of the newspapers's construction of modern culture.
