Les discours ruraux, urbains et périurbains du cinéma québécois

Ce projet s’intéresse aux représentations que fait le cinéma des territoires et à la manière dont ces représentations reflètent des grands enjeux socio-spatiaux. L’espace cinématographique devient une clé d’entrée pour l’analyse géographique. Cette analyse porte plus particulièrement sur les représentations que fait le cinéma québécois contemporain des espaces urbains, ruraux et périurbains. Les récits et les représentations spatiales qui les composent se positionnent souvent sur les enjeux socio-spatiaux, produits par l’histoire nationale et les processus socioéconomiques. La proposition d’analyser les représentations cinématographiques en lien avec le contexte socioéconomique vise deux principaux objectifs conceptuels. D’une part, elle s’intéresse à une meilleure compréhension du façonnement des discours sur l’espace, en ce qui a trait à leur émergence et leur négociation. D’autre part, l’analyse vise une définition élargie des espaces ruraux, urbains et périurbains contemporains, en révélant la complexité et simultanément, la simplification dont ils font l’objet, ainsi que les enjeux qui leurs sont associés. Il s’agit d’exploiter la cinématographie québécoise comme un outil d’analyse qui permet de dévoiler la diversité des discours socio-spatiaux. Des approches quantitatives et qualitatives d’interprétation des discours sont jumelées pour réaliser une analyse complète. La méthode retenue est l’analyse critique du discours (ACD), qui tient compte des rapports idéologiques et vise à la dénaturalisation du discours. En quelques mots, l’analyse consiste en l’identification de relations entre les représentations spatiales et le contexte socioéconomique duquel elles ont émergé. Le cadre opérationnel est constitué d’un corpus de 50 films québécois réalisés entre 1980-2008, « lus » à l’aide d’une grille de lecture originale et analysés avec des méthodes d’analyse spatiale et statistique, combinées à une interprétation qualitative. L’analyse quantitative révèle que le monde urbain et le monde rural sont souvent mis en opposition. Les films font de Montréal le principal pôle urbain, tandis que le reste du Québec est associé au milieu rural. Influencées par les flux culturels et économiques globaux, les représentations montréalaises suggèrent une ville fragmentée et continuellement en mouvement. En opposition à ces représentations urbaines, les cinéastes envisagent l’espace rural comme étant exempt de travail, axé sur le chez-soi et doté d’un esprit communautaire. Il est suggéré que la ville, toujours en croissance, restreint les possibilités d’un développement communautaire fort. Face à une ville transformée par la globalisation et en perte d’authenticité, une forme de régionalisme est observée. Ce dernier associe un ensemble de valeurs à une communauté ou à un territoire, afin de se distinguer devant des forces globalisantes qui semblent homogénéiser les valeurs. Pourtant, l’analyse quantitative laisse voir des contradictions au sein de chaque entité géographique ou milieu. L’analyse qualitative permet d’approfondir l’interprétation et révèle sept grands discours sur les espaces urbains et ruraux. Sont notamment identifiés des discours sur la contestation de la modernité urbaine, sur la réappropriation du milieu de vie par les citoyens et sur un espace rural parfois brutal. Cette analyse amène à conclure que la diversité des discours s’explique par l’hétérogénéité des pratiques socio-spatiales, qui remettent en question l’idée d’un discours national homogène. Cela témoigne de l’évolution et la négociation des regards que nous posons sur nos espaces. Au final, cette thèse contribue à une meilleure utilisation du matériel cinématographique comme support d’étude géographique en proposant une approche méthodologique claire et originale. Sur un plan conceptuel, elle rappelle la complexité et le dynamisme des représentations territoriales québécoises, ainsi que les stratégies de négociation des cinéastes face aux enjeux socio-spatiaux vécus dans la province.

Investigations on Some Titania Supported Catalysts

Titania is a versatile metal oxide with multiple applications. Titania supported catalysts are reported to be much more active compared to conventional silica or alumina supported ones in some reactions. TiO2 (anatase) having high surface area, with better crystallinity and high onset temperature of rutilation can be prepared by thermal hydrolysis of titanyl sulfate solution under controlled conditions. Calcinations at 350oC for 6 hrs were necessary to crystallize anatase. Method of preparation and percentage of the loaded metal oxides have greater influence on surface area. Drastic decrease in surface area was observed upon rutilation. Rutilation started at different temperatures depending on the metal oxide and the method of preparation. TiO2 should be characterized with high surface area, phase purity and high onset temperature of rutilation.Which should be well above the optimum temperature of a designated reaction in which it is employed as a catalyst. Variation in physical properties, depending upon the method of preparation is greater in TiO2 supported catalysts. Methanation activity was found to be highly dependent on nickel concentration present on the surface of the pellets. The methanation activity is strongly influenced by support material. The rate and turn over frequency of methanation and toluene oxidation activity of these catalysts are also equally important from an industrial point of view.

Studies on immobilization of Bacteria

Cell immnhilizatinn technology in a rapidly expanding arna in the endeavour of microbial fnrmentatiwn.During the lnmt 15 years anveral prnceafinn have been developed and more are in developmental atage of approaching commercial utilizatinn.In the present programme it was planned to develop an optimized process for the innobilization of alpha amylase producing Bacillus polymyxa (CBTB 25) an isolate obtained from Cochin University campus primarily for the production of alpha-amylase.Optimal concentration of support material that attributaa stability and maximal activity to the immobilized cell beads was determined using different concentrations of sodium aliginate as support and estimation of amylase production.An overeall assessment of the data obtained for the various studies conducted denotes that immobilized cells synthesize alpha-amylase at comparable rates with free cells and produce reducing sugara at a higher level than free cells.Results indicated that both phosphate and citrate buffers could be used for disrupting the immobilized beads since they enforced maximal release of cells through leaching from the beads within one hour.On comparative analysis it was observed that immobilized cells could synthesize alpha amylase at similar levels with free cells of B.polymyxa.On Co-immobilization of B.Polymyxa with S.cerevisiae,the co-immobilizate beads could effeciently convert starch directly to ethanol with a yield of 14.8% at 1 : 2 ratio.

Fronteiras da nova economia institucional

These papers deal with some main topics in new institutional economics. I make a survey of the literature, considering the contributions presented by Buchanan, Tullock, Coase, Olson and North to modern approaches to political economy. In fact, the first article is very simple. It should be used as support material in economics seminars at undergraduated level. The second one is an academic paper and deals basically with the contributions of public choice theory to the political understanding.

Avaliação de bactérias nitrificantes em filtros biológicos submersos aerados

This study investigates a new treatment system of wastewater by anaerobic and aerobic biological filters for nitrogen modification. The main objective of this study was evaluate, on a pilot scale, quantitatively and qualitatively the bacterian nitrifying community in a experimental sewage treatment system made by aerobics biological filters in series, in search of figure out the dynamic of nitrogen modification process. It was collected and laboratorial analysed microbiologically, regarding NMP of Nitrosomonas e Nitrobacter, and physical-chemically considering nitrogen sequence. We conclude that: the association in aerobic biological filters under nutrition controlled conditions and oxygen level allows the appearance of bacterian community responsible for the nitrogen modification; the method used, despite its limitations, provided the selection of autotrophic nitrifying microorganisms, allowing the identification of Nitrosomonas and Nitrobacter; the flow direction tested in the experimental unit did not affect the nitrifying bacterial community, certainly because they were kept drowned and did not occur flow speed that could breake the formed biomass; the nitrification process happened in aerated biological filters in all phases of the research, comproved by microbiological tests; in the third phase of the research the increase of the oxygen rate was significant for the nitrificant bacterian community in the aerate biological filters, allowing its growth, occurring relation between the efficiency of nitrification system and the quantity of organisms responsible for this process; the conduit used in aerated biological filters showed satisfactory performance support material to the nitrifying bacteria development

Remoção de nitrogênio em biofiltros aerado e anóxico, com alto índice de vazios e sem remoção de lodo

The improper disposal of nitrogen in receiving water courses causes problems such as toxicity to living beings through the consumption of oxygen to meet the nitrogen demand, eutrophication and nitrate contamination of aquifers. For this reason it is often necessary to be carried out complementary treatment of wastewater to eliminate or reduce the concentration of this compound in the wastewater. The objective of this study is to evaluate the biological removal of nitrogen compounds using submerged aerated and anoxic filters as post-treatment of an anaerobic system, with low cost and innovative technology, which in previous studies has shown high removal efficiency of organic matter and great potential biological nitrogen compounds removal. The simple design with perforated hoses for air distribution and filling with plastic parts proved to be very efficient in relation to organic matter removal and nitrification. The system presented, in the best stage, efficiency in converting ammonia to nitrate by 71%, and produced a final effluent concentration below 10 mg / L of NH3-N. In addition, carbon concentration was removed by 77%, producing final effluent with 24 mg/L COD. However, denitrification in anoxic filter was not effective even with the addition of an external carbon source. There was a reduction of up to 56% of nitrogen caused by the process of simultaneous nitrification and denitrification (SND). The high voids space presented by this type of support material coupled with direct aeration of the sludge, allows the respiration of biomass retained between the endogenous phase, increased cell retention time and sludge retention capacity, producing a final effluent with turbidity less than 5 UT and total suspended solids around 5.0 mg/L

The dead core model applied to beads with immobilized cells in a fed-batch cephalosporin C production bioprocess

Viable cells immobilized in inert supports are currently studied for a wide range of bioprocesses. The intrinsic advantages of such systems over suspended cultures incite new research, including studies on fundamental aspects as well as on the industrial viability of these non-conventional processes. In aerobic culture of filamentous fungi, scale-up is hindered by oxygen mass transfer limitation through the support material and bioprocess kinetics must be studied together with mass transfer limitation. In this work, experimental and simulated data of cephalosporin C production were compared. Concentrations in the bulk fermentation medium and cellular mass profiles inside the bioparticles are focused. Immobilized cells were used in a tower bioreactor, operated in fed-batch mode. To describe the radial variation of oxygen concentration within the pellet, a dead core model was used. Despite the extremely low sugar concentrations, bioreaction rates in the pellets were limited by the dissolved oxygen concentration. Cell growth occurs only in the outer layers, a result also confirmed by scanning electron microscopy. (C) 2001 Elsevier B.V. Ltd. All rights reserved.

Avaliação da política curricular paulista: perspectiva docente sobre os cadernos do professor e do aluno

The current curriculum policy of the Secretary of Education in the State of Sao Paulo introduced into the education environment the Registrar of Teacher and Student - support material to ease the teacher's work and the student's learning, in order to address all the curriculum components created as strategy of learning. The resulting guidelines that aim to transform the everyday policies of educational institutions and the individuals who compose them, are incorporated into the school experience. These decisions, however, do not transfer into life outside the learning environment nor are they translated into the work of the teachers exactly as their creators intended. Thus, in order to better understand the curriculum policies introduced by the Registrar in schools, it is essential to comprehend the viewpoint of the teachers who themselves are both the targets and agents of curriculum policy, and later the Registrar. For that was made reflexive interviews with eigth teachers that teach in São Paulo metropolitan region, than we could see that they adapt their external determinations in their own reality

Depressão e apoio social percebido por mães de crianças hospitalizadas

This study was performed as a requirement of the final course in Nursing. The study is cross-cutting, in order to identify associations between socioeconomic factors, education, child hospitalization in the ICU or not, degree of depression and level of social support (material, affective, emotional, informational and positive social interaction) and how to identify subgroups of mother - child vulnerable. Constitute themselves as subjects, mothers of children 0 to 17 years, 11 months and 29 days in hospital after the second day of hospitalization in the pediatric unit of a State Hospital Interior Paulista. Data collection was initiated after obtaining the assent of the Research Ethics Committee, as well as signing the consent form. We used the following instruments to collect data: the data form for socioeconomic and hospitalization; Beck Depression Inventory and Medical Outcomes Study (MOS). We obtained the result that there is a strong association between availability and social support and income per capita and the degree of depression, but did not find an association between time and hospital stay and whether the child was admitted to the ICU or not. We conclude that it is necessary to establish treatment services from the patient’s family, plus an appropriate social service support to meet this big demand for mothers who need support

Circulação de textos midiáticos entre alunos de escola pública básica

The text characterizes the reading of media-related materials by students of the public basic education system in the State of São Paulo, based on a systematic observation of the circulation of press texts within the school daily life. In a study carried out during two academic years with groups of students from fundamental and secondary education classes belonging to two different schools situated in the outskirts of a town in the interior of the state, the students' reports on their appropriation of media-based information obtained from a variety of sources were analyzed, with particular emphasis on written newspapers. During the period investigated individual and group interviews, as well as texts produced by the students, were taken as points of departure for the analysis. Among the aspects noted from the contact with communication media is the establishment of press information inside the school, albeit with fragmentary repercussions, not fully integrated into the pedagogical daily life, but somewhat circumstantial in the students' lives. The themes that receive more attention circulate through the television, mediated by family or peers, but not by teachers. A proposal for the analysis of these data is made, followed by concrete suggestions as to the treatment to be given to support material, texts and media-based issues at school, taking into account the resources available and the school context such as it appears nowadays.
