2011 — Multiscale mechanics and structural design of periodic cellular materialsAbstract
Les matériaux cellulaires périodiques, aussi connus sous le nom de matériaux réseaux, sont constitués d'un grand nombre d'éléments de micro-treillis réticulés qui sont assemblés de manière périodique ; ils sont construits en assemblant un grand nombre de cellules composées d'un petit nombre d'éléments pour former un pavé dont la périodicité peut être infinie. Les matériaux réseaux servent à modifier les propriétés des matériaux solides qui les constituent selon la topologie des cellules ou la densité relative, . Le développement des matériaux réseaux permet d'élargir la gamme de matériaux pouvant servir dans la conception d'applications avancées.Les progrès récents dans cette nouvelle … Read more

2011 — Variability and uncertainty in probabilistic seismic hazard analysis for the island of MontrealAbstract
Le processus de conception sismiques actuelles pour les structures à Montréal est basé sur l'édition 2005 du Code National du Bâtiment du Canada (CNBC 2005), qui est basé sur un niveau de risque correspondant à une probabilité de dépassement de 2% en 50 ans. Le code est basé sur le spectre uniforme d'aléa (UHS) et a été dérivé par la Commission Géologique du Canada (CGC) avec une version modifiée du logiciel F-RISK. Cette version du code fut développée sans considérer formellement la contribution de l'incertitude épistémique sur l'aléa. Les sources de l'incertitude épistémique sont reliées à la formulation sources sismiques. … Read more

2011 — Predicting language and literacy outcomes of typically-developing and at-risk English-speaking elementary students in French immersion programsAbstract
Many children around the world are educated in a second language, be they speakers of the majority language of the community in which they are educated or speakers of a minority language. Research has demonstrated the effectiveness of second language immersion for typically-developing students and students who are disadvantaged in the academic environment of schooling due to low levels of academic ability, disadvantaged socio-economic background, or minority ethnic group status (for a review see Genesee, 2006). In contrast, although it is generally thought that the level and kind of first language (L1) ability that children acquire prior to coming to … Read more

2011 — Studies of the role of growth hormone and its receptor in obesityAbstract
Bien que la thérapie aux hormones de croissance (GH) puisse réduire l'adiposité efficacement dans certaines formes d'obésité, les traitements aux GH de l'obésité idiopathique n'ont peu voire pas d'effet. Nous pensons que cela pouurait être dû à une modification dans l'expression du récepteur aux hormones de croissance (GHR) dans les tissus adipeux. En premier lieu, nous avons évalué les niveaux de GHR dans les tissus adipeux provenant d'une cohorte de femmes allant de maigres à obèses et trouvé une réduction significative du récepteur.Afin de comprendre les mécanismes impliqués, nous avons analysé les effets de trois facteurs associés à l'obesité (TNFα, … Read more

2011 — Three essays on economics of non-market institutionsAbstract
This thesis is a collection of three essays on the economic consequences of a number of primarily non-market institutions, more precisely visual artists' compensation scheme, religiosity and social influence. Methodology varies across the different chapters of this thesis: I use experimental, empirical and theoretical tools. In its contents this thesis contributes to the growing efforts made by scholars and researchers to build a bridge among social science disciplines, mainly psychology, sociology and law with economics. In my first essay I model a work of art as a lottery in order to compare the two dominant compensation schemes for visual artists … Read more

2011 — A positive youth development coach education program and the United Nations millennium development goalsAbstract
En 2000, l'Organisation internationale des Nations Unies (ONU) fut l'hôte d'un sommet international afin de fixer leurs principaux buts et objectifs. De ce sommet sont nés les objectifs du Millénaire pour le développement (OMD), un ensemble de huit objectifs qui abordent des problèmes sociaux importants dans le monde. Les Nations Unies ont reconnu les possibilités du sport et de l'activité physique en tant qu'OMD de l'ONU. Les évidences empiriques ont démontré d'une part que le sport est un outil puissant qui peut encourager le développement d'habiletés de vie chez les jeunes athlètes et d'autre part que les entraîneurs jouent un … Read more

2011 — Common good and the concept of expropriation in international law on foreign investment: Determinacy of substance in legitimacy of structureAbstract
This thesis, exploring the rule of law for international rules, offers a human bond of common good between determinacy of substance and legitimacy of structure of rules in order to evaluate international obligations of States in international law on foreign investment. In an in-depth exposition of the theoretical underpinnings and practices underlying the normative structure of rules in international law, the thesis critically questions the legal reasoning embedded in—and the authority of rules borrowed from—principles and precedents or moral and political evaluations by arbitrators in interpretation of States' contractual, customary, and treaty obligations in investment arbitrations. With crucial moral, political, … Read more

2011 — Studies of the mitochondrial import receptor, Tom70, preprotein targeting and importAbstract
La plupart des protéines mitochondriales sont synthétisées comme préprotéines dans le cytosol et ensuite importées dans l'organite d'un façon post traductionnel. L'adressage des protéines dans la mitochondrie requiert la reconnaissance de différents facteurs : les chaperons cytosoliques, Hsc70 et Hsp90, et les récepteurs de la translocase de la membrane externe (TOM), Tom20 et Tom70. L'activité de Hsc70 et de Hsp90 dépend d'un cycle de hydrolyse de l'ATP et est régulée par certaines co-chaperons, incluant Tom70. Tom70 est dotée d'un domaine en pince TPR qui fixe un motif conservé à l'extrémité carboxylique des chaperons : EEVD. Cette interaction est essentielle pour … Read more

2011 — Food paths, architecture and urban form. A case studyAbstract
Architectural scholars have studied the origins, growth, and development of New World settlements and their works document aspects such as land division, infrastructure, construction materials and building techniques. Often overlooked, however, are the physical effects that everyday food-related activities had in shaping these places.This thesis explores the relationships that linked subsistence to the architecture of the cold-climate settlement of Montreal in seventeenth and eighteenth century New France. It investigates food production cycles and transformation processes, and seeks to reconstruct the spatial-temporal chains through which food made its way from field to table to wastes in a pre-industrial urban context. It … Read more

2011 — Protein folding cooperativity and functional dynamicsAbstract
The research reported in this Thesis has contributed to the development of methodologies in the study of disorder-to-order transitions, as well as given insight into the thermodynamics and kinetics of specific, biologically relevant processes in a small DNA binding protein, PBX homeodomain through a combination of Nuclear Magnetic Resonance (NMR) dynamics experiments and Differential Scanning Calorimetry (DSC). The major conclusions and contributions to original knowledge from each chapter are outlined below. A model is presented where protein folding kinetic data for multiple mutations at individual hydrophobic core positions can be well accounted for by two parameters describing the dependence of … Read more

2011 — Connectivity for line-of-sight networks in higher dimensionsAbstract
Les réseaux de lignes de visée ont été introduits par Frieze et al. pour modéliser les communications sans fil en milieu urbain. Leur modèle est basé sur une grille bidimensionnelle de points en forme de tore. Deux points de la grille sont dits mutuellement visibles si ils sont situés sur la même ligne ou la même colonne du tore et si la distance entre eux est dans un certain intervalle prédéterminé. La distance est mesurée en utilisant le norme L1. Un graphe aléatoire est obtenu en plaçant un noeud à chaque point de la grille indépendamment avec la même probabilité … Read more

2011 — The narrative and discursive references to children and audience duality in The Gospel of MarkAbstract
La présente thèse examine la rhétorique qui sous-tend les cas narratifs (de 5,21 à 43; de 7,24 à 30; de 9,14 à 29) et discursifs (9,33 à 37; de 10,13 à 16) dans la langue de Marc portant sur les enfants, et analyse comment et dans quelle mesure la langue Marcan relative aux enfants est présentée comme rhétorique pour s'adresser clairement aux niveaux élites et non-élites de la double audience à laquelle s'adresse l'Évangile, en se fondant sur la théorie développée par Henderson. La thèse soutient que les récits de guérisons d'enfants favorisent la construction d'une conception inscrite de l'enfant … Read more

2011 — Perceptions of old age in comparative perspective: does the welfare state matter?Abstract
One of the presumed consequences of the growing ascendency of population aging on social reforms and political discourses in Europe is a generalized uneasiness with old age in the welfare state. Drawing on the fourth wave of the European Social Survey, this thesis seeks to map out perceptions of old age across European welfare states. It argues that the welfare states theory can be a useful comparative tool to explain both individual perceptions of old age and intergenerational patterns found on European soil. Results show that the effect of welfare state types on individual perceptions is largely insignificant; rather, a … Read more

2011 — Validation of the Hayes Ability Screening Index (HASI) for intellectual disabilities among federal inmates in QuebecAbstract
Background: Researchers and clinicians have stressed the importance of indentifying individuals with an intellectual disability (ID) in the criminal justice system, yet there is a lack of convenient instruments available for early screening of ID by non-professionals. Objectives: The goal of the present study was to assess the predictive validity of a screening measure for ID, the Hayes Ability Screening Index (HASI), in a correctional setting. Methods: This cross-sectional study of 324 male offenders recruited from Quebec's Regional Reception Centre of the Correctional Service of Canada compared results of the HASI with two screening subscales of the Wechsler Adult Intelligence … Read more

2011 — Modeling and optimization of electro-optic materials used in Mach-Zehnder optical switchesAbstract
Les nouvelles technologies demandent des réseaux optiques flexibles. Les commutateurs optiques offrent une capacité de transmission efficace et utile pour ces applications. La large bande passante et le faible voltage de modulation sont les avantages des commutateurs optiques en espace. L'objectif de cette recherche est d'optimiser le profil de dopage dans le guide afin de maximiser l'effet d'électro-optique tout en minimisant les pertes optiques. Les guides d'ondes semi-conducteurs à hétérostructure double ont été utilisés pour les appareils de commutation optique. La meilleure combinaison du ratio d'extinction, d'efficacité de puissance et des dimensions globales des commutateurs a été trouvée dans un … Read more

2011 — Dyna learning with deep belief networksAbstract
The objective of reinforcement learning is to find "good" actions in an environment where feedback is provided through a numerical reward, and the current state (i.e. sensory input) is assumed to be available at each time step. The notion of "good" is defined as maximizing the expected cumulative returns over time. Sometimes it is useful to construct models of the environment to aid in solving the problem. We investigate Dyna-style reinforcement learning, a powerful approach for problems where not much real data is available. The main idea is to supplement real trajectories with simulated ones sampled from a learned model … Read more

2011 — Genome-wide screen for novel regulators of Parkinson's disease genes in «Drosophila melanogaster»Abstract
Introduction: Compromised mitochondrial integrity leads to neuronal cell death in Parkinson's disease and other neurodegenerative diseases. Cells have several quality control mechanisms in place to counteract dysfunction and preserve a healthy mitochondrial network. Recent studies have implicated the autosomal recessive Parkinson's disease genes, Parkin and Pink1, in a common pathway regulating mitochondrial quality control. Together, Parkin and Pink1 promote isolation and selective degradation of damaged mitochondria, but the mechanisms governing this process are unclear. Methods: The goal of our study was to use a genetically sensitized Drosophila model of Parkinson's disease to identify novel regulators of the Pink1/Parkin pathway. We … Read more

2011 — Regulation of signal tranducer and activator of transcription-1 and cell death by mammalian target of RapamycinAbstract
mTOR (mammalian target of rapamycin), la cible de la rapamycine chez les mammifères, est une kinase de type sérine-thréonine très bien conservée à travers les phyla, qui est responsable de la réponse aux mitogènes anabolisants et aux substrats métaboliques tel que l'insuline, les acides aminés et l'ATP. Une réduction de l'activité de TOR peut également permettre l'initiation de réponses cataboliques. Chez S. cerevisiae, le stress physique et la déficience en éléments nutritifs induisent une réponse transcriptionnelle qui nécessite des phosphatases associées à TOR ainsi que la translocation nucléaire de facteurs de transcriptions dépendant de la réaction aux éléments de stress. … Read more

2011 — Reading Muslim women: The cultural significance of Muslim women's memoirsAbstract
This study looks at a growing trend in literature: memoirs written by women from Islamic countries. It will deal specifically with the cultural significance of these books in North American culture with special consideration of how the Muslim religion is depicted and therefore relayed to the North American audience. Finally, this paper will look at how these memoirs, and other texts like them, can be used in the classroom to teach against Islamophobia. Read more

2011 — The role of muscle cocontraction in motor learningAbstract
In everyday activity we interact with objects and need to learn how to stabilize our limbs and apply appropriate forces. During learning the central nervous system adapts to the dynamics of the limb and the environment by means of formation of an accurate internal model. In the early stages of learning in the presence of novel force fields muscle cocontraction increases. Thoroughman and Shadmehr (1999) have described cocontraction as a wasted contraction. However, Franklin et al. (2003) have shown that the increase in muscle cocontraction has an important role in learning to stabilize the limb and offset the effect of … Read more

2011 — Combustion of surrogate jet fuel components in premixed stagnation flamesAbstract
La combustion du carburant d'aviation, connu sous le nom de Jet A, dans les turbines à gaz aro-drives est un processus complexe qui n'est pas entièrement compris. Bien que de nombreuse études on été faites pour produire des modèles num ́eriques et chimiques du Jet A, l'absence de consensus dans la littérature montre qu'il reste encore du travail. Ce travail est une étude de trois substances pures, qui sont représentatifs de la composition chimique qui constituent les carburants d'aviation. Le n-décane représente les alcanes présents dans le Jet A, le méthylcyclohexane les hydrocarbures cycliques, et le toluène les aromatiques. Les … Read more

2011 — The role of energy expenditure in resource acquisition and energy allocation in free-ranging North American red squirrels (Tamiasciurus Hudsonicus)Abstract
L'énergie est la devise de la vie puisqu'elle est nécessaire à tous les organismes vivants pour survivre et se reproduire. J'ai examiné le rôle central des dépenses énergétiques dans la vie des écureuils roux (Tamiasciurus hudsonicus) femelles en liberté au Yukon (Canada, 61 °N 138 °W) pendant qu'elles acquéraient leur énergie et l'attribuaient entre différentes activités favorisant leur survie et succès reproductif. Lorsqu'elles s'approvisionnaient de cônes d'épinette blanche (Picea glauca) à l'automne, leur acquission d'énergie correspondait à une réponse fonctionnelle de type III. Lorsque les cônes étaient rares, les écureuils changeaient pour s'approvisionner en champignons, alors que lorsque les cônes … Read more

2011 — The locking-decoding frontier for generic dynamicsAbstract
The intuition that the amount of classical correlations between two systems be bounded by their size does not hold true in general for quantum states. In the setting of information locking, measurements on a pair of quantum systems that appear to be completely uncorrelated can become maximally correlated with a small increment in the size of one of the systems. A new information locking scheme based on generic unitary channels is presented and a strengthened definition of locking based on a measure of indistinguishability is used. The new definition demonstrates that classical information can be kept arbitrarily low until it … Read more

2011 — Bioresorbable inorganic setting systems for bone repairAbstract
Calcium phosphate-based materials have become the first choice for surgeons when they look for a synthetic material for the repair and augmentation of bone. Numerous studies and commercial use over the last three decades have made these materials popular options. These materials are not without their negative aspects, and properties such as poor in vivo resorption and low setting pH are well documented. Magnesium phosphates represent a poorly investigated group of materials with chemical structures similar to those of the calcium phosphates.In this thesis we investigate magnesium phosphates for use as inorganic materials for bone repair. We demonstrated that heat-treatment … Read more

2011 — The sound of positive emotion: The vocal acoustic properties involved in the expression and perception of interestAbstract
Emotion plays an important role in psychotherapy. In order to understand more about the interaction between emotional functioning and the psychotherapeutic process, research into the moment to moment fluctuations of emotional experience is essential. However, subjective measurement of the momentary changes of emotion has proved problematic. The current body of work seeks to address this measurement challenge by examining the vocal acoustic properties of participants' speech within therapeutic style interviews, specifically, the momentary fluctuations of the emotion of interest. A second study examines the vocal cues that trainee therapists use in deciphering participants' emotional processing. Results revealed that the vocal … Read more

2011 — Breast cancer cells affect bone cell differentiation and the bone microenvironmentAbstract
Breast carcinoma is the most commonly diagnosed cancer among women worldwide, with approximately 1 in 7 expected to be affected during her lifetime. The spread of breast cancer to secondary sites is generally incurable. Bone is the preferred site of metastasis, where the development of a secondary tumour causes severe osteolysis, hypercalcemia and a considerable pain burden. However, how breast cancer cells establish supportive interactions with bone cells is not well understood. We have examined the effects of factors released from MDA-MB-231 and 4T1 breast cancer cells on the differentiation of C57BL6 mouse bone marrow cells. Treatment with cancer-derived factors … Read more

2011 — Skating mechanics of change of direction maneuvers in hockey playersAbstract
Ice hockey is a popular winter sport that involves many skating skills improved by coaching instruction and numerous hours of practice. Once the basic mechanics of skating have been honed, the open game context requires rapid skating transitions between skating skills so as to effectively navigate about the ice surface to evade opponents and move in strategic tandem with teammates. Consequently, a player's performance relates in large part to effective change of direction maneuvers. The purpose of this study was to observe the kinetics of change of direction maneuvers in hockey players while wearing one of two skate models: a … Read more

2011 — Structural and functional correlates of mental musical transformationAbstract
Music represents both a ubiquitous element in human cultures and a highly complex discipline to which some individuals devote decades of practice. Music is therefore an ideal medium with which to probe human auditory perception over a wide range of skill. Differences in brain structure and function have been reported in musicians (vs. untrained individuals), but because of methodological limitations, the links bringing together behavior, structure and function have remained indirect. This thesis consists of three neuroimaging studies that, together, elucidate some of the functional and anatomical substrates of aspects of melodic perception. Study 1 used functional magnetic resonance imaging … Read more

2011 — Modeling trace element uptake by plants grown in contaminated soilAbstract
Risk assessors are often asked to estimate the concentration of a trace element in the edible part of a plant based on soil properties. More accurate models are needed to better assess the risks associated with the consumption of plants growing in contaminated soils. Although the importance of different soil physico-chemical properties on trace element bioavailability is recognized, the effect of plant physiological processes have received less attention. This thesis reports efforts to integrate soil physico-chemical properties and plant physiological factors in the modeling of trace element uptake by plants and provides a reflection on the assessment of the risks … Read more

2011 — Nearly rigid analytic modular forms and their values at CM pointsAbstract
Nous démontrons un variante p-adique d'un résultat classique de Shimura sur l'algébricité des valeurs des formes modulaires et de certaines de leurs dérives non-holomorphes aux points CM. Plus précisément, nous définissons un analogue rigide analytique de l'opérateur différentiel de Shimura-Maass pour les formes modulaires rigide analytiques sur le demi-plan p-adique de Cerednik-Drinfeld. Cette définition nous conduit a définir l'espace des formes modulaires presque rigide analytiques, qui correspond dans notre analogie a l'espace des formes modulaires presque holomorphes. Notre résultat principal est un énoncé d'algébricité des valeurs des formes modulaires presque rigide analytiques en des points CM dansle demi-plan p-adique de … Read more

2011 — Comprehensive study of the immunomodulatory properties of bone marrow-derived mesenchymal stromal cellsAbstract
Over the course of the last decade, mesenchymal stromal cells (MSC) have made a remarkable entry in the field of cell-based immunotherapy. In vitro, MSC were shown to modulate the immune response, either by acting as an immunosuppressant on several immune cells, or upon IFN-γ stimulation, as an antigen presenting cell (APC) for the priming of CD4+ T cells. Although a vast array of in vivo experiments in animals and humans has undeniably proven the immunological properties of MSC, the exact mechanisms by which MSC mediate their effects remain unclear. In Chapter 1, I presented a succinct review of the … Read more

2011 — Responsibility and penality in the laws of PlatoAbstract
Cette thèse examine Les Lois de Platon, offrant une nouvelle perspective sur l'importance des différences entre les trois personnages. Ces différences pointent à une tension clé entre la voix singulière de la loi à proprement parler, et les voix multiples du projet philosophique de Platon à l'intérieur de la loi. À son tour, cette tension fournit non seulement l'opportunité mais aussi les dilemmes pour ce projet, qui a pour but principal le développement de la responsabilité humaine authentique. Ceci se dégage particulièrement dans le droit pénal délinéé au Livre 9, qui doit prévoir la punition des criminels malgré le fait … Read more

2011 — Comprendre l'intimité: une forme de pouvoir au sein des audiences de la commission Bouchard-TaylorAbstract
This thesis investigates the status of intimacy in late modernity. It adresses two questions: how should we consider intimacy today? And how can intimacy help us understand social phenomena such as the Bouchard-Taylor Commission?To answer these questions, intimacy is conceptualized as a form of power that regulates the space of social differentiation that exists between individuals in modern societies. The analysis is inspired by philosophical hermeneutics, but also a series of transdisciplinary approaches enabling us to account for the various dimensions of the issue. The thesis provides a close reading of 64 interventions made during the Quebec Citizen's Forum of … Read more

2011 — An epistemic analysis of authenticationAbstract
Authentication protocols aim to prevent agent impersonation: A is authenticated to B if B knows who A is. Many formal approaches have been used to verify authentication in distributed systems; however, although authentication is directly related to agent knowledge, it has only been formally defined using process algebra, usually in terms of constraints on the order of protocol events. In response, we use epistemic modal logic to define authentication in terms of common knowledge as a form of coordinated action. We apply our definition to verify the Needham-Schroeder-Lowe Public-Key Protocol, as well as its predecessor, the Needham-Schroeder Public-Key Protocol, which … Read more
