L'étude porte sur un écosystème forestier riverain d'un grand lac subarctique (Lac à l'Eau-Claire) en état moribond. La dégradation des arbres suggère une progression spatiale que l'on a reconstituée au moyen de l'analyse dendrochronologique. Nous avons formulé l'hypothèse que l'augmentation des précipitations de neige et la hausse du niveau lacustre suggérées par des travaux antérieurs pourraient avoir causé la dégradation de la forêt. L'objectif principal de cette recherche est de déterminer les différentes facettes du phénomène à l'origine de la dégradation des arbres. Le site à l'étude a été divisé en cinq zones subparallèles au rivage selon les caractéristiques des divers états des arbres. Une étude dendrochronologique a permis de reconstituer les processus récents et passés. Ils ont été situés dans le contexte des fluctuations historiques des niveaux d'eau du lac afin de préciser le gradient écologique en lien avec le régime des perturbations physiques. Les données ont permis de distinguer cinq périodes où les facteurs climatiques et locaux ont influencé la population forestière riveraine : 1) colonisation du site à l'étude (1704), 2) première phase d'installation (1800-1850), 3) deuxième phase d'installation et première phase de mortalité (1850-1930), 4) apparition de la frange forestière (1930-1950), 5) deuxième phase de mortalité (1950-2006).

In Marie-Claire Blais's trilogy Soifs, the history of the 20th Century is registered in an inter-cultural and inter-discursive realm both as a history which is "infernal" (chaotic, violent, fragmented) and as one which is civilizing. The objective of this study is to observe and comment on this double inscription, to evaluate how it takes charge of and modulates signs and representations already in circulation in social discourse. The author seeks to discern the inter-discursive work of manipulation and translation of social discourse from a point of view which is at once formal, narrative, linguistic and ideological, to ultimately identify the ideological work of Blais's novels on a fundamental stake within current society: the historical past.

This thesis offers an analysis of the intertextual practices in Marie-Claire Blais's trilogy Soifs by which we explore the way the author integrates into her novels significant literary figures and texts in order to underline one of the trilogy's constant themes: the innocence and suffering of the victims of the twentieth century and of today. In this fiction saturated with literary and artistic references, literature appears as a standpoint on modern world and works are considered to be acts of creation that opposes to the "choeur de la destruction" the voices of writers and artists.

Thesis advisor: Carling Hay / Modern day climate change is exacerbating sea level change both locally and globally. The magnitudes of these changes are dependent on numerous global and regional factors that make it difficult to accurately project local sea level into the future. In Alaska, there are many processes contributing to sea level changes along the coast. In particular, there is substantial vertical land movement, in the form of uplift and subsidence, due to the isostatic adjustment of the land once burdened by ice sheets. In Northern Alaska, there is an additional source of land motion that occurs because the flat, tundra landscape is underlain by ~100-300m of permafrost. This permafrost is currently melting and the area is experiencing land subsidence because of it. This study refines sea level projections along northern Alaska by accounting for this extra climate signal. The addition of permafrost-melt induced isotropic land subsidence in projections for the northern coast of Alaska results in sea level rise estimates at the end of the century that double previously published projections. These improved Alaska projections will be vital for the coastal communities, especially in coming decades, in order to minimize losses of coastal property and infrastructure. / Thesis (BS) — Boston College, 2018. / Submitted to: Boston College.

Ma production artistique et ce mémoire se concentrent sur la manipulation de contextes de la vie de tous les jours par l'entremise de thèmes récurrents dans ma pratique, tels l'humour, la monstruosité et le grotesque. Ce mémoire fait état des divers éléments symboliques qui constituent mon esthétique en analysant mon processus créatif ainsi que les objectifs et les questionnements inhérents à ma pratique. Ce texte met également en évidence la répétition en tant que méthode, l'anticipation des réactions du public comme moteur de création ainsi que les dynamiques positives et négatives qui influencent mon travail. / My artistic production and this thesis are focused on the manipulation of everyday life contexts through recurring themes in my practice, such as humor, monstrosity, and the grotesque. This thesis reports on the various symbolic elements that constitute my aesthetic, analyzing my creative process as well as the objectives and questions inherent in my practice. This text also highlights repetition as a method, the anticipation of audience reactions as a creative engine, as well as the positive and negative dynamics that influence my work.
