Les déficits cognitifs peuvent-ils aider à distinguer un trouble psychotique avec toxicomanie d’une psychose induite par consommation de méthamphétamines?

Introduction - Dissociating a primary psychotic disorder (PPD) with concurrent substance use from substance-induced psychosis (SIP) can be a difficult task since several symptoms are similar. The dichotomy between negative and positive symptoms in schizophrenia has been hypothesized as a predictor, as the former is not typically a feature of a dual disorder (Potvin, Sepehry, & Stip, 2006). Objective - This study explored the possibility of distinguishing subgroups within our sample using cognitive functioning to further identify factors that could help the differential diagnosis between a PPD co-occurring with substance-use and a methamphetamine (MA) induced psychosis. The hypothesis stipulates that individuals with a PPD should present with different cognitive deficits compared to individuals with SIP. Methods - This study used the data collected as part of a longitudinal study (the MAPS project) that took place in Vancouver BC, Canada. 172 individuals presenting with psychosis and MA abuse were recruited. Substance use, symptoms severity and cognitive deficits were assessed. Results - Cluster analyses revealed two profiles: individuals in Cluster 1 had a poorer performance on the Gambling task net score (M=-28,1) as well as on the Hopkins Verbal Learning Test - Revised (HVLT-R; M=63) % of retention score compared to those in Cluster 2. Individuals in Cluster 1 also had more negative symptoms than individuals in Cluster 2, t=2,29, p<0.05 and were more likely to have had a psychiatric diagnosis, X2(3) = 16.26, p< 0.001. Conclusion - Results suggest that cognitive predictors might help identify PPD that co-occur with MA abuse.

Examen des liens entre les comportements de soutien affectif maternel et les profils d'apprentissage en contexte de prise de décisions affectives chez les enfants de 48 mois

Research suggests that the quality of mother-child interactions play a role in the development of executive functioning (EF) during the preschool years. Most studies have examined cool EF, which represent general decision-making abilities during problem solving activities. The present study is concerned with hot EF, which is typically elicited by problem solving situations that require emotional regulation. Hot EF plays a role in affective decision-making (ADM). Prior research on ADM has examined its relation to sex, age, and neurological factors. Studies have not examined whether mother-child interactions play a role in the development of ADM ability. Thus, the importance of proximal environmental factors such as maternal responsiveness remains to be examined. The present study first examines the main effect of the quality of maternal responsiveness on the ADM ability. Second, the effect of sex and the interaction between the quality of maternal responsiveness and learning profiles of 48-month-old children were examined. Finally, this study also examines whether there were differences between the maternal responsiveness of children who abandoned the ADM test and those who completed the task. A subsample of 191 children (109 girls and 82 boys) and their mothers participated in a lab visit as part of the Pilot-Quebec Longitudinal Study of Child Development (P-QLSCD, Quebec Health, 1997).  Children completed several activities both individually and with their mothers. ADM was evaluated using the Children’s Gambling Task (CGT, Kerr & Zelazo, 2001). Maternal responsiveness was assessed using the MacArthur Story-Stem Battery (MSSB , Bretherton, Oppenheim, Buchsbaum, Emde & the MacArthur Narrative Group, 1990) and the Affective climate coding scheme (Boutin, Parent, et Lapalme-L’Heureux, 1998). Results revealed no significant principal effect between the quality of maternal responsiveness and ADM ability but a significant interaction between the quality of maternal responsiveness and child learning profiles. However, this interaction was only significant for boys. Boys who received medium to high levels of responsiveness showed better learning profiles during hot EF tasks than those who received low levels of responsiveness. In addition, children who abandoned the experiment (N=26) received lower scores on maternal responsiveness than those who completed the task. The present results suggest that high quality mother-child interactions are important for the development of cognitive processing in emotional contexts.

Characterization of the unfolding of a weak focus and modulus of analytic classification

The thesis gives a geometric description for the germ of the singular holomorphic foliation associated with the complexification of a germ of generic analytic family unfolding a real analytic vector field with a weak focus at the origin. We show that two such germs of families are orbitally analytically equivalent if and only if the germs of families of diffeomorphisms unfolding the complexified Poincaré map of the singularities are conjugate by a real analytic conjugacy. The Z2-equivariance of the family of real vector fields in R^4 is called the “real character” of the system. It is expressed by the invariance of the real plane under the flow of the system which, in turn, carries the real asymptotic expansion of the Poincaré map when the parameter is real. After blowing up the singularity, the pullback of the real plane by the standard monoidal map intersects the foliation in a real Möbius strip.  The blow up technique allows to “realize” a germ of generic family unfolding a germ of diffeomorphism of codimension one and multiplier −1 at the origin as the semi-monodromy of a generic family unfolding an order one weak focus. In order to study the orbit space of the Poincaré map, we perform a trade-off between geometry and dynamics under the Glutsyuk point of view (where the dynamics is linearizable near the singular points): in the resulting “unwrapping coordinate” the dynamics becomes much simpler, but the price we pay is that the local geometry of the ambient complex plane turns into a much more involved Riemann surface. Over the latter, two notions of translations are defined. After taking the quotient by the lifted dynamics we get the orbit space, which turns out to be the union of three complex tori and the singular points (this space is non- Hausdorff). The Glutsyuk invariant is then defined over annular-like regions on the tori. The translations, the real character and the fact that the Poincaré map is the square of the semi-monodromy map, relate the different components of the Glutsyuk modulus. That property yields only one independent component of the Glutsyuk invariant.

Architecture et mission pédagogique : regards sur le campus de l'Université de Montréal et de l'école des HEC à l'ère d'une société de la connaissance

In the era of the knowledge society characterized by the importance of constant innovation, various dimensions of social life are going through notable renewals. The New Technologies of Information and Communication (NTIC) are offering a large panel of new possibilities that affects the traditional mode of operating of various institutions. In this context, Universities become fundamental actor, by contributing to the high education of the population through their activities of teaching and research. It seems that the traditional mission of universities is going through major changes. Lots of new possibilities permit by the NTIC affects the traditional way of teaching and doing research and we also talk about new kind of unprecedented relations between universities, state and the industry. We offer to explore the impact of all these changes on the physical development of universities through a look at a case study of the campus of Université de Montréal and the business school of HEC Montreal. Our work discuss about the influence of these changes in the physical organization of the university, more specifically on the architecture of the buildings. Through a look at the project of construction of a new campus situated at Outremont, we have attended to study actual tendencies and concerns about university buildings. We then attended to analyse the impacts of these developments on the organisation of universities buildings through a study of the architectural features of the new school of HEC Montréal.

Vers une intégration écologique des technologies de l’information et de la communication en éducation en Afrique du Centre et de l’Ouest : une approche culturelle

In an increasingly interconnected world, developing countries need to be active participants in the information society. Contact between different cultures is on the rise; cultural resources have become consumer resources; and cultural minorities across the globe who have integrated information and communications technology (ICT) into their societies risk domination by the cultures of developed countries on the global communication networks. In order for a culture to stand its ground online, it is essential that its educational institutions train learners in their own cultural context, and promote and encourage the development and use of endogenous educational content. It is from this perspective that this qualitative study seeks, as a first objective, to assess the cultural content being accessed and distributed via ICT in schools of developing African countries; as a second objective, to describe existing barriers to an integration of ICT that would encourage online cultural promotion in these schools; and finally as a third and final objective, to identify practical strategies for an ecological ICT integration in these schools. Such an integration would be sustainable, adapted to local contexts, and foster the full participation of its teachers and students. To achieve these objectives, we have used a multi-case study based on interviews with 168 teachers and 230 students from 34 pioneer ICT schools located in five West and Central African countries; which content was analyzed according to each specific objective. Adopting the strategies described in our results would allow these schools to overcome some of the barriers they are facing, and to favour the ecological integration of ICT necessary for developing a more equitable information society, thus reducing the digital divide between the ‘information haves and have-nots’.

Chanter le développement au Burkina Faso :
ethnographie de la rencontre entre deux champs d'action

In the urban context of Burkina Faso, music and songs with a message for social education have become an intersection for traditionnal social practice, news cultural economies and participative development programs. This practice responds to specific local and international issues. As a common resource of social and artistic communication, music represents a strategic resource for musicians and local associations. For the former, we can discuss the role of the musician in contemporary society, between impoverisation and globalization. For the latter, music and songs with a message for social education are an innovative approach of Information, Éducation et Communication pour la santé (IEC/santé) and Communication pour le Changement de Comportement (CCC). In this research, we present the diverse levels of collaboration between musicians artist and local associations working in the healthcare sector in Burkina Faso. The ethnography presents the particular sphere of each group and analyzes the social negociations that results from their encounter. The research question proposed here falls between cultural studies and the study of social change. Hence, the chain of creation-production-diffusion commoditization allows us to study the history of complex concepts such as culture and developpement in a particular setting in Frenchspeaking West Africa.

La logique et les logiques : la question du pluralisme

Starting from the seminal work of Boole, Frege and Russell, the dissertation seeks to clarify the issue of logical pluralism in the era of the proliferation of non-classical logics and the developments in theoretical computer science and proof theory. Two “historical” chapters are scheduled: the first chapter articulate the absolutism of Frege and Russell, taking care to show how it condemns the possibility to consider alternative structures and logics; the fourth chapter describes the path that led Carnap from the adoption of the syntactic method to the formulation of the principle of tolerance, then goes on to display Carnap‟s instrumentalism in philosophy of Logic and mathematics. Opening with the analysis of an intuitive interpretation of linear logic, the second chapter then turns to the establishment of a form of logico-mathematical pluralism with the help of order theory and category theory. The third chapter delineates the playground of revisionism (philosophical positions surrounding the debate between monism and pluralism) and then provides an argument against the thesis that denies the reality of the conflict between rival logics, all this being done by adopting the substructural logic point of view. The fifth chapter shows that each of the three main approaches to the concept of logical consequence (model-theoretic, proof-theoretic and dialogical) supplies a framework sufficiently general to establish pluralism. In short, the dissertation is a defence of logical pluralism.

L'utopie numérique : discours et réalités sur la numérisation des salles de cinéma illustrés par le cas de l'entreprise DigiScreen

The goal of this thesis is to demonstrate the impossible realization of the "myth of Hollywood digital disruption" as described by Kira Kitsopanidou. This idea put simply suggests the enlargement of film diversity in theaters due to the advent of digital technology. This myth, which perpetuates the idea of Hollywood’s death, was carried by several texts (espacially thoses produced by mass media) and participate in what can be qualified, following Foucault, as a "discursive formation" revolving around technology. The first chapter will analyze the main differences between this utopic discourse and reality based on the socio-economic factors affecting the processes of innovation’s implementation, particulary thoses related to the movie theaters. Secondly, we will consider the realities that affect the implementation of digital technology in movie theaters. Advantagously, these also explain the slowness of this process, a situation that was interpreted by the discourse as a delay. The third chapter will illustrate the concepts discussed in the previous chapters, using as a case study the example of DigiScreen, a company that wanted to increase film diversity in movie theaters by providing theatre owners with digital equipment at discounted prices. DigiScreen in some ways encapsulates the hopes generated by the digital utopia. Finally, we will look at different cases which draw a portrait of the digitization of theatres in the early years of the twenty-first century.

Bases génétiques de la sténose valvulaire aortique calcifiée

Aortic valve stenosis (AVS) is a valvular heart disease caused by calcification leading to incomplete opening of the aortic valve. Calcification of valve leaflets associated with aging is the most common cause of AVS. AVS pathogenesis involves lipoprotein deposits, chronic inflammation and calcification of the aortic valve leaflets. Our study aims to identify genes associated with AVS in order to better understand its mechanisms and potentially identify new therapeutic targets.  We recruited 190 cases with AVS of different severity and 192 controls matched for age and sex. Then we conducted a candidate gene association study using single nucleotide polymorphisms (SNPs). The candidate genes selected include: (1) those with polymorphisms putatively implicated in previous genetic association studies of AVS (APOB, APOE, ESR1, PTH  and VDR); (2) those with validated associations to inflammatory diseases (IL-10, TNFAIP3) or lipid metabolism (LDLR ,PCSK9) in genome-wide association studies and, (3) genes impliated in AVS pathogenesis from studies with animal models and thought to be involved in calcification (BMP2, CCR5, CTGF, LRP5, MXS2, WNT3); tissue remodeling (CTSS, MMP9) or lipid metabolism (SMPD1).  For the first two categories of genes, we tested the SNPs reported to be associated in the literature and, in the third category we used a tag-SNP approach which consists of selecting a subset of SNPs to capture variability in the target region. Finally, 81 SNPs in 18 genes were tested. We found a nominal association of BMP2 (OR=1.55, CI: 1.14 – 2.10, p=0.004) and LRP5 (OR=1.47, CI: 1.06 – 2.03, p=0.023) with presence of AVS after adjustment for coronary heart disease.  The genes BMP2 and LRP5, which are known to be involved in calcification based on animal models, are associated with AVS. The result of the current study should be validated in a larger independent cohort in the near future and then, it could also be extended to the study of other genes.

Être motard : Hells Angels malgré tout

Regardless of the intense public focus, members of the Hells Angels organization in Quebec continue to be active in illegal markets. What does it means to be a Hells Angels and how has the organization remained resilient to law enforcement and internal conflicts in the criminal underworld? Although financial and organizational strengths help the members overcome difficulties, the main argument in this study places a focus on the Hells Angels reputation as the key element accounting for their continuity. I embrace Gambetta’s thesis (2009) which states that the persistence of belief in the immortality of the criminal group generates a self-fulfilling prophecy that renders the organization increasingly resilient. This thesis is extended to the Hells Angels context and applied to interviews conducted with bikers, non-biker inmates and staff members in Quebec penitentiaries. Findings support the main thesis in that the organization’s reputation for being dangerous offers that group an effective economic and symbolic value. However, there is a drawback of this reputation that has to be considered. The Hells Angels label in Quebec generates negative aspects for individuals who endorse it. It is interesting to understand the impact of such a labelling phenomenon, through different phases of their collective career.

Étude empirique des commentaires et application des techniques de résumé par extraction pour la redocumentation

Programs documentation is very useful to programmers during maintenance tasks, especially for program comprehension. However, the documentation is not always available or it may be badly written. In such cases, redocumentation becomes so necessary.      In this work, we propose a redocumentation technique that consists in generating comments by using extraction  summary techniques.      For this purpose, we conducted an empirical study to analyze the quantitave and qualitative aspects of comments. Particularly, we were interested in studying comment distribution over different types of construct and studying the frequency of documentation for each construct type. We propose a comment taxonomy to classify them according to their content and quality.      Given the results of the empirical study, we decided to summarize Java classes by extracting the comments of methods and constructors. We defined several heuristics in order to determine the most relevant comments to be extracted. After that, we applied these heuristics to Java classes from three projects in order to generate summaries. Finally, we compared the generated summaries (generated comments) to the reference ones (original comments) by using the metric ROUGE.

Prédiction de l'attrition en date de renouvellement en assurance automobile avec processus gaussiens

The field of auto insurance is working by cycles with phases of profitability and other of non-profitability. In the phases of non-profitability, insurance companies generally have the reflex to increase the cost of premiums in an attempt to reduce losses. For cons, very large increases may have the effect of massive attrition of the customers. A too high attrition rate could have a negative effect on long-term profitability of the company. Proper management of rate increases thus appears crucial to an insurance company. This thesis aims to build a simulation tool to predict the content of the insurance portfolio held by an insurer based on the rate change proposed to each insured. A proce- dure using univariate Gaussian Processes regression is developed. This procedure offers a superior performance than the logistic regression model typically used to perform such tasks.
