La revue de la Chambre de commerce de Montréal et la modernisation de la métropole dans les années 1950 et 1960

Pendant les années 1950 et 1960, Montréal se modernise sur plusieurs aspects. L’influence de l’administration de la ville sur cette modernisation est bien connue. Toutefois, les perspectives des acteurs extérieurs sont souvent ignorées. Ce mémoire examine donc les opinions de la Chambre de commerce de Montréal sur la modernisation de la métropole québécoise lors de ces deux décennies. La source principale utilisée pour effectuer cette étude a été la revue hebdomadaire de la Chambre, Commerce-Montréal. Dans le premier chapitre, les opinions de la Chambre de commerce sur la gouvernance municipale sont examinées. Celles-ci montrent que la Chambre percevait l’assainissement des moeurs politiques et l’amélioration de l’efficacité administrative comme intrinsèques à la modernisation de Montréal. Le deuxième chapitre porte sur la circulation automobile et le transport en commun. La Chambre proposait des moyens d’accélérer le débit de la circulation qu’elle jugeait crucial pour la modernisation de la métropole. Le troisième chapitre traite du développement urbain. D’après la Chambre, la modernisation de Montréal exigeait le renouvellement du cadre bâti de la ville, tant résidentiel que commercial. L’étude de ces trois thèmes confirme que, pendant la période 1950-1970, la Chambre de commerce a contribué de manière significative aux débats concernant la modernisation de Montréal. Nous relevons aussi que l’organisme, malgré son désir de paraître apolitique, a été influencé par sa fonction de représentant de la communauté d’affaires francophone. L’importance accordée à la rentabilité de la modernisation, ainsi que la hiérarchisation sociale attribuée à certains sujets, confirment notamment les orientations conservatrices de l’organisme.

Le téléroman, un mode de connaissance du social : l’entrée dans la vie adulte de quatre jeunes personnages de Yamaska

Inspired by the epistemological approach of Gilles-Gaston Granger and the sociological approach of Howard Becker, this thesis focuses on Quebec’s téléroman as a mean of social knowledge. Based on the theoretical conception of entry into adult life elaborated by various researchers such as the French sociologist Olivier Galland, this research aims to assess the sociological value of the Quebec’s téléroman as a form of representation of this phenomenon. To achieve this goal, we describe the entry into adult life of four characters from the téléroman Yamaska : Geoffroy Carpentier, Olivier Brabant, Théo Carpentier and Ingrid Harrisson. By applying the theories proposed by the French sociologist Olivier Galland to these characters, our goal is to study and describe the adequacy, or inadequacy, of such a theory when applied to the experiences of young adults today broadcast in the chosen téléroman. Through the characters of Yamaska, the study aims to see how the theory fits, or not, to the television series, and investigates whether it provides additional knowledge about the phenomenon of entry into adult life. This will help us determine the type of knowledge broadcast through this TV fiction, and focus on the influence exerted on the content and the way it is broadcast by the téléroman’s structure.

Représentations sociales de la dangerosité psychiatrique chez les intervenants en santé mentale : une anthropologie du risque

Le présent mémoire porte sur les représentations sociales de la dangerosité en psychiatrie chez les intervenants de proximité (infirmières, préposés, et agent de sécurité), d’un milieu de soins psychiatriques. Nous cherchons à explorer comment ces intervenants perçoivent et interprètent les risques inhérents à leur métier et comment ils y réagissent en situation d’incertitude. Les concepts de dangerosité, d’ « individu dangereux » et de risque en psychiatrie sont abordés dans le présent mémoire, à travers un angle historique, social et anthropologique, suivant les lectures de Michel Foucault; de Robert Castel; de Ian Hacking; et de Mary Douglas. De l’observation participante dans une unité de soins psychiatriques aigus et des entrevues semi-structurées ont été réalisées auprès d’une dizaine d’intervenants en santé mentale. Une approche ethnographique et interprétative nous a permis de dégager les principales récurrences, divergences et contradictions intra et inter intervenants sur la question de la dangerosité et du risque en psychiatrie. Les résultats sont séparés en fonction de trois grands thèmes : 1) représentations sociales de la dangerosité 2) perceptions du risque au travail 3) réactions face au risque perçu. L’analyse de nos résultats montre que les connaissances qu’ont les intervenants sur la dangerosité ne se limitent pas à celles produites par le savoir expert, elles s’ouvrent aussi sur leur propre réalité clinique. De plus, contrairement aux prédictions du savoir expert, la différence observée entre les pratiques de contrôle des intervenants n’est pas la conséquence d’une surestimation du risque ni d’un manque d’information « objective » sur les facteurs de risque du comportement agressif, mais s’explique davantage en fonction de la présence ou de l’absence d’un lien thérapeutique et du degré de reconnaissance sociale dans les interactions entre les soignants et les soignés. Les éléments qui renforcent ou limitent l’établissement d’un lien de confiance sont explicités dans le présent mémoire.

Les effets d’un cercle pédagogique sur le regard professionnel et les pratiques pédagogiques des enseignants du 3e cycle du primaire en grammaire actuelle

Notre recherche doctorale vise à décrire les effets d’un cercle pédagogique sur les pratiques pédagogiques et didactiques d’enseignants du 3e cycle du primaire en grammaire actuelle. Ce projet s’inscrit dans une recherche plus large intitulée « Étude des effets, sur les pratiques pédagogiques des enseignants et la compétence à écrire des élèves, d’un dispositif de formation à la grammaire nouvelle qui intègre des exemples de pratiques sur vidéo et permet un partage d'expertise ». Elle vise à éclairer les conditions d’efficacité d’une formation continue sur différentes dimensions du développement professionnel au regard de la formation elle-même et de son effet sur le transfert des pratiques en classe. Pour y parvenir, nous avons analysé les échanges provenant des cercles pédagogiques vécus durant une année scolaire. Nous avons également analysé deux activités de grammaire, avant et après la formation en grammaire offerte sous forme de capsules. Ces observations en classe ont été captées sur vidéo, dans la classe de 18 enseignants participant à notre expérimentation. Nous avons enfin analysé les réponses des participants à un questionnaire sur leur perception à l’égard du dispositif de formation auquel ils ont participé pendant neuf mois. Nos analyses montrent qu’un dispositif de formation à la grammaire actuelle qui met au cœur de la formation l’analyse d’exemples de pratiques sur vidéo soutient le développement du regard professionnel des enseignants dans le contexte du cercle. Ceux-ci observent plus d’interactions et les interprètent mieux, de manière plus approfondie. Nos observations ont également montré que les enseignants développent majoritairement des pratiques dans leur classe, qu’ils développent de nouveaux savoirs en lien avec le cadre théorique de la nouvelle grammaire et qu’ils modifient la vision qu’ils ont de la grammaire actuelle au fil des rencontres. Cette recherche peut enrichir les connaissances scientifiques sur le développement professionnel et influencer les formateurs d’enseignants de même que les cadres des milieux scolaires pour ajuster l’offre de formation continue afin de la rendre plus efficace.

Dépistage du décrochage scolaire à l’aide d’informations administratives ou auto-rapportées

Les adolescents qui décrochent de l’école secondaire arrivent difficilement à s’intégrer dans une économie axée sur le savoir et éprouvent plusieurs problèmes d’ajustement à l’adolescence et à l’âge adulte. Pour prévenir le décrochage scolaire, une étape cruciale consiste à dépister efficacement les élèves les plus à risque. Deux formes de dépistage axées sur des données peuvent être utilisées en milieu scolaire: une forme utilisant des informations auto-rapportées par les élèves à partir de questionnaires, et une autre fondée sur des informations administratives consignées au dossier des élèves. Toutefois, à notre connaissance, l’efficacité de ces différentes modalités n’a jamais été comparée directement. De plus, il est possible que l’efficacité relative de ces outils de dépistage soit différente selon le sexe de l’élève. Cette étude vise à comparer différents outils de dépistage pour prédire le décrochage scolaire, en tenant compte de l’effet modérateur du sexe. Les outils utilisés seront a) un questionnaire auto-rapporté validé (Archambault et Janosz, 2009) et b) un outil conçu à l’aide de données administratives, créé par une commission scolaire du Québec. La comparaison de ces outils est effectuée en termes de qualités psychométriques et d’aspect pratique pour le milieu scolaire. Pour ce faire, un échantillon de 1557 élèves (50% de garçons), âgé entre 14 et 18 ans est utilisé. Les résultats indiquent que l’indice administratif possède une capacité discriminante adéquate, mais inférieure à celle de l’indice auto-rapportée, jugée excellente. L’effet modérateur du sexe n’a pas été confirmé. Les avantages et inconvénients respectifs de ces deux modes de dépistage sont discutés.

Sustainability of Medicinal Plants in Kerala Economic Considerations in Domestication and Conservation of Forest Resources

The present study on the sustainability of medicinal plants in Kerala economic considerations in domestication and conservation of forest resources. There is worldwide consensus on the fact that medicinal plants are important not only in the local health support systems but in rural income and foreign exchange earnings. Sustainability of medicinal plants is important for the survival of forest dwellers, the forest ecosystem, conserving a heritage of human knowledge and overall development through linkages. More equitable sharing of the benefits from commercial utilization of the medicinal plants was found essential for the sustainability of the plants. Cultivation is very crucial for the sustainability of the sector. Through a direct tie-up with the industry, the societies can earn more income and repatriate better collection charges to its members. Cultivation should be carried out in wastelands, tiger reserves and in plantation forests. In short, the various players in the in the sector could find solution to their specific problems through co-operation and networking among them. They should rely on self-help rather than urging the government to take care of their needs. As far as the government is concerned, the forest department through checking over- exploitation of wild plants and the Agriculture Dept. through encouraging cultivation could contribute to the sustainable development of the medicinal plant sector.

Statistical Machine Learning Techniques for the Prediction of Learning Disabilities in School-Age Children

Learning Disability (LD) is a general term that describes specific kinds of learning problems. It is a neurological condition that affects a child's brain and impairs his ability to carry out one or many specific tasks. The learning disabled children are neither slow nor mentally retarded. This disorder can make it problematic for a child to learn as quickly or in the same way as some child who isn't affected by a learning disability. An affected child can have normal or above average intelligence. They may have difficulty paying attention, with reading or letter recognition, or with mathematics. It does not mean that children who have learning disabilities are less intelligent. In fact, many children who have learning disabilities are more intelligent than an average child. Learning disabilities vary from child to child. One child with LD may not have the same kind of learning problems as another child with LD. There is no cure for learning disabilities and they are life-long. However, children with LD can be high achievers and can be taught ways to get around the learning disability. In this research work, data mining using machine learning techniques are used to analyze the symptoms of LD, establish interrelationships between them and evaluate the relative importance of these symptoms. To increase the diagnostic accuracy of learning disability prediction, a knowledge based tool based on statistical machine learning or data mining techniques, with high accuracy,according to the knowledge obtained from the clinical information, is proposed. The basic idea of the developed knowledge based tool is to increase the accuracy of the learning disability assessment and reduce the time used for the same. Different statistical machine learning techniques in data mining are used in the study. Identifying the important parameters of LD prediction using the data mining techniques, identifying the hidden relationship between the symptoms of LD and estimating the relative significance of each symptoms of LD are also the parts of the objectives of this research work. The developed tool has many advantages compared to the traditional methods of using check lists in determination of learning disabilities. For improving the performance of various classifiers, we developed some preprocessing methods for the LD prediction system. A new system based on fuzzy and rough set models are also developed for LD prediction. Here also the importance of pre-processing is studied. A Graphical User Interface (GUI) is designed for developing an integrated knowledge based tool for prediction of LD as well as its degree. The designed tool stores the details of the children in the student database and retrieves their LD report as and when required. The present study undoubtedly proves the effectiveness of the tool developed based on various machine learning techniques. It also identifies the important parameters of LD and accurately predicts the learning disability in school age children. This thesis makes several major contributions in technical, general and social areas. The results are found very beneficial to the parents, teachers and the institutions. They are able to diagnose the child’s problem at an early stage and can go for the proper treatments/counseling at the correct time so as to avoid the academic and social losses.

Studies on some aspects of mangrove ecosystem in a tropical estuary"

The situation in the backwaters of Kerala, which reportedly had about 70,000 ha of mangroves, is unique in the sense that there has been a total conversion to other uses such as paddy cultivation, coconut plantation, aquaculture, harbour development and urban development In order to save and restore what is left over national and international organisations are mounting pressure on scientists and policy makers to work out ways and means conserving and managing the mangrove ecosystems. In this context, it has been observed in recent years that mangrove vegetation has remained intact in isolated pockets of undisturbed areas in the Cochin estuarine system and also that there is resurgence of mangroves in areas of accretion and silting. The candidate took up the present study with a view to make an inventory of the existing mangrove locations, the areas of resurgence, species composition, zonation and other ecological parameters to understand their dynamism and to suggest a mangement plan for this important coastal ecosystem

Speaker identification using models for phonemes

Motivation for Speaker recognition work is presented in the first part of the thesis. An exhaustive survey of past work in this field is also presented. A low cost system not including complex computation has been chosen for implementation. Towards achieving this a PC based system is designed and developed. A front end analog to digital convertor (12 bit) is built and interfaced to a PC. Software to control the ADC and to perform various analytical functions including feature vector evaluation is developed. It is shown that a fixed set of phrases incorporating evenly balanced phonemes is aptly suited for the speaker recognition work at hand. A set of phrases are chosen for recognition. Two new methods are adopted for the feature evaluation. Some new measurements involving a symmetry check method for pitch period detection and ACE‘ are used as featured. Arguments are provided to show the need for a new model for speech production. Starting from heuristic, a knowledge based (KB) speech production model is presented. In this model, a KB provides impulses to a voice producing mechanism and constant correction is applied via a feedback path. It is this correction that differs from speaker to speaker. Methods of defining measurable parameters for use as features are described. Algorithms for speaker recognition are developed and implemented. Two methods are presented. The first is based on the model postulated. Here the entropy on the utterance of a phoneme is evaluated. The transitions of voiced regions are used as speaker dependent features. The second method presented uses features found in other works, but evaluated differently. A knock—out scheme is used to provide the weightage values for the selection of features. Results of implementation are presented which show on an average of 80% recognition. It is also shown that if there are long gaps between sessions, the performance deteriorates and is speaker dependent. Cross recognition percentages are also presented and this in the worst case rises to 30% while the best case is 0%. Suggestions for further work are given in the concluding chapter.

Spatio-Temporal Changes in the Wetland Ecosystem of Cochin City using Remote Sensing and GIS

Urban developments have exerted immense pressure on wetlands. Urban areas are normally centers of commercial activity and continue to attract migrants in large numbers in search of employment from different areas. As a result, habitations keep coming up in the natural areas / flood plains. This is happening in various Indian cities and towns and large habitations are coming up in low-lying areas, often encroaching even over drainage channels. In some cases, houses are constructed even on top of nallahs and drains. In the case of Kochi the situation is even worse as the base of the urban development itself stands on a completely reclaimed island. Also the topography and geology demanded more reclamation of land when the city developed as an agglomerative cluster. Cochin is a coastal settlement interspersed with a large backwater system and fringed on the eastern side by laterite-capped low hills from which a number of streams drain into the backwater system. The ridge line of the eastern low hills provides a welldefined watershed delimiting Cochin basin which help to confine the environmental parameters within a physical limit. This leads to an obvious conclusion that if physiography alone is considered, the western flatland is ideal for urban development. However it will result in serious environmental deterioration, as it comprises mainly of wetland and for availability of land there has to be large scale filling up of these wetlands which includes shallow mangrove-fringed water sheets, paddy fields, Pokkali fields, estuary etc.Chapter 1 School 4 of Environmental Studies The urban boundaries of Cochin are expanding fast with a consequent over-stretching of the existing fabric of basic amenities and services. Urbanisation leads to the transformation of agricultural land into built-up areas with the concomitant problems regarding water supply, drainage, garbage and sewage disposal etc. Many of the environmental problems of Cochin are hydrologic in origin; like water-logging / floods, sedimentation and pollution in the water bodies as well as shoreline erosion

Sustainable Solid Waste Management Through Ecological Footprint Analysis – A Solution To Kochi City, India

Kochi, the commercial capital of Kerala, South India and second most important city next to Mumbai on the Western coast is a land having a wide variety of residential environments. Due to rapid population growth, changing lifestyles, food habits and living standards, institutional weaknesses, improper choice of technology and public apathy, the present pattern of the city can be classified as that of haphazard growth with typical problems characteristics of unplanned urban development especially in the case of solid waste management. To have a better living condition for us and our future generations, we must know where we are now and how far we need to go. We, each individual must calculate how much nature we use and compare it to how much nature we have available. This can be achieved by applying the concept of ecological footprint. Ecological footprint analysis (EFA) is a quantitative tool that represents the ecological load imposed on earth by humans in spatial terms. The aim of applying EFA to Kochi city is to quantify the consumption and waste generation of a population and to compare it with the existing biocapacity. By quantifying the ecological footprint we can formulate strategies to reduce the footprint and there by having a sustainable living. The paper discusses the various footprint components of Kochi city and in detail analyses the waste footprint of the residential areas using waste footprint analyzer. An attempt is also made to suggest some waste foot print reduction strategies thereby making the city sustainable as far as solid waste management is concerned.
