Le Statut comparé de l'autofiction chez Benjamin Constant et Amélie Nothomb : une histoire de genre?

Le genre autobiographique, malgré une popularité qui ne se dément pas depuis deux siècles, ne bénéficie pas d’une définition claire. Cet article se propose de montrer que cela est sans doute dû à l’hybridité intrinsèque de ce genre qui se traduit aussi par un pacte autobiographique complexe. Plus précisément, en s’appuyant sur les cas de Constant et de Nothomb, sera démontré que la lecture qui est faite des écrits intimes détermine bien souvent le genre. En ce qui concerne en particulier ces deux auteurs, leur personnalité changeante, contradictoire voire affabulatoire repousse le genre autobiographique dans ses limites, illustrent l’adage selon lequel le roman est plus vrai que la réalité vécue.  

Review of the effectiveness of vehicle activated signs

This paper reviews the effectiveness of vehicle activated signs. Vehicle activated signs are being reportedly used in recent years to display dynamic information to road users on an individual basis in order to give a warning or inform about a specific event. Vehicle activated signs are triggered individually by vehicles when a certain criteria is met. An example of such criteria is to trigger a speed limit sign when the driver exceeds a pre-set threshold speed. The preset threshold is usually set to a constant value which is often equal, or relative, to the speed limit on a particular road segment. This review examines in detail the basis for the configuration of the existing sign types in previous studies and explores the relation between the configuration of the sign and their impact on driver behavior and sign efficiency. Most of previous studies showed that these signs have significant impact on driver behavior, traffic safety and traffic efficiency. In most cases the signs deployed have yielded reductions in mean speeds, in speed variation and in longer headways. However most experiments reported within the area were performed with the signs set to a certain static configuration within applicable conditions. Since some of the aforementioned factors are dynamic in nature, it is felt that the configurations of these signs were thus not carefully considered by previous researchers and there is no clear statement in the previous studies describing the relationship between the trigger value and its consequences under different conditions. Bearing in mind that different designs of vehicle activated signs can give a different impact under certain conditions of road, traffic and weather conditions the current work suggests that variable speed thresholds should be considered instead.

Invasive Aquatic Invasion: The Spread of Variable Leaf Milfoil in Maine

Variable leaf milfoil, Myriophyllum heterophyllum, has been present in Maine since 1970. We created an analysis area including seventeen infestation sites and all bodies of water within a forty mile buffer. We also eliminated all water locations with a size less than 7,101 km2, the size of the smallest infestation site, Shagg Pond. Within those specifications we randomly selected seventeen un-infested bodies of water and used them as our uncontaminated sample. We looked for relationships between presence and number of boat launches, and proximity to a populated area. Using the Mann-Whitney test, we compared the sample size of non-infested lakes to the infested lakes. We found there was no significant difference in all three variables on the infestation of variable leaf milfoil.

Multi-Objective Pipe Smoothing Genetic Algorithm For Water Distribution Network Design

This paper describes the formulation of a Multi-objective Pipe Smoothing Genetic Algorithm (MOPSGA) and its application to the least cost water distribution network design problem. Evolutionary Algorithms have been widely utilised for the optimisation of both theoretical and real-world non-linear optimisation problems, including water system design and maintenance problems. In this work we present a pipe smoothing based approach to the creation and mutation of chromosomes which utilises engineering expertise with the view to increasing the performance of the algorithm whilst promoting engineering feasibility within the population of solutions. MOPSGA is based upon the standard Non-dominated Sorting Genetic Algorithm-II (NSGA-II) and incorporates a modified population initialiser and mutation operator which directly targets elements of a network with the aim to increase network smoothness (in terms of progression from one diameter to the next) using network element awareness and an elementary heuristic. The pipe smoothing heuristic used in this algorithm is based upon a fundamental principle employed by water system engineers when designing water distribution pipe networks where the diameter of any pipe is never greater than the sum of the diameters of the pipes directly upstream resulting in the transition from large to small diameters from source to the extremities of the network. MOPSGA is assessed on a number of water distribution network benchmarks from the literature including some real-world based, large scale systems. The performance of MOPSGA is directly compared to that of NSGA-II with regard to solution quality, engineering feasibility (network smoothness) and computational efficiency. MOPSGA is shown to promote both engineering and hydraulic feasibility whilst attaining good infrastructure costs compared to NSGA-II.

Consumption smoothing in Latin America: an empirical assessment of present value models

The study aims to assess the empirical adherence of the permanent income theory and the consumption smoothing view in Latin America. Two present value models are considered, one describing household behavior and the other open economy macroeconomics. Following the methodology developed in Campbell and Schiller (1987), Bivariate Vector Autoregressions are estimated for the saving ratio and the real growth rate of income concerning the household behavior model and for the current account and the change in national cash ‡ow regarding the open economy model. The countries in the sample are considered separately in the estimation process (individual system estimation) as well as jointly (joint system estimation). Ordinary Least Squares (OLS) and Seemingly Unrelated Regressions (SURE) estimates of the coe¢cients are generated. Wald Tests are then conducted to verify if the VAR coe¢cient estimates are in conformity with those predicted by the theory. While the empirical results are sensitive to the estimation method and discount factors used, there is only weak evidence in favor of the permanent income theory and consumption smoothing view in the group of countries analyzed.

Laws of large numbers for non-additive probabilities

We apply the concept of exchangeable random variables to the case of non-additive robability distributions exhibiting ncertainty aversion, and in the lass generated bya convex core convex non-additive probabilities, ith a convex core). We are able to rove two versions of the law of arge numbers (de Finetti's heorems). By making use of two efinitions. of independence we rove two versions of the strong law f large numbers. It turns out that e cannot assure the convergence of he sample averages to a constant. e then modal the case there is a true" probability distribution ehind the successive realizations of the uncertain random variable. In this case convergence occurs. This result is important because it renders true the intuition that it is possible "to learn" the "true" additive distribution behind an uncertain event if one repeatedly observes it (a sufficiently large number of times). We also provide a conjecture regarding the "Iearning" (or updating) process above, and prove a partia I result for the case of Dempster-Shafer updating rule and binomial trials.

Correlação entre qualidade de ensino e os investimentos financeiros

O senso comum vincula a falta de qualidade do ensino público à insuficiência de recursos financeiros disponíveis. Também no meio acadêmico, pesquisadores alegam a inexistência de recursos suficientes para que seja fornecida uma educação de qualidade, enquanto outros acadêmicos defendem que, apesar de poucos recursos disponíveis, o maior problema é a falta de eficiência dos investimentos financeiros pelo gestor público. Nesta pesquisa foram realizadas duas análises: a primeira correlacionando a qualidade do ensino aos investimentos financeiros sob uma perspectiva quantitativa destes investimentos, utilizando um modelo de análise bivariável; enquanto a segunda análise correlaciona a qualidade do ensino aos investimentos financeiros sob uma perspectiva qualitativa destes investimentos, utilizando a alocação dos recursos financeiros para qualificá-los. A análise dos resultados desta pesquisa comprova que os investimentos financeiros no ensino não devem ser vinculados somente em função da quantidade dos investimentos financeiros. Os investimentos financeiros podem ser alocados em diversos tipos de despesas no universo educacional, tais como: remuneração de magistério, alimentação e transporte escolar, distribuição de uniformes, materiais didáticos, infra-estrutura, dentre outros. Algumas dessas despesas agregam maior valor ao ensino que outras. Assim, a prioridade dos programas e políticas educacionais municipais está diretamente ligada à qualidade do ensino municipal.

La vision estrategica en el sector publico : la experiencia de las empresas publicas brasilenas

La presente tesis aborda el tema de la Visión Estratégica en el contexto de la empresa pública brasilefía, Siendo que para facilitar el análisis, la practica estratégica es evaluada en términos de Planeamiento Empresarial, Planeamiento Estratégico o Administración Estratégica según sea el caso. EI objetivo de la investigación es análizm y determinar el grado de utilización y apoyo de la referida herramienta gerencial en la optimización de la gestión cotidiana de dichas empresas públicas. Así, son analisados el nivel de suceso, las falias, así como sus oportunidades de utilización, a la luz dei referencial teórico existente y salvando las restricciones, por cuanto la mayor parte de la literatura encontrada versa sohre la empresa privada. Los resultados de la investigación, bibliográfica, documental y de campo practicadas en empresas públicas brasilefías de grande porte, tales como Compafíía Vale do Rio Doce, Petrobrás, Embratel, Eletrobrás y BNDES, muestran los diferentes grados de aplicación de la Visión Estratégica en las mismas. Siendo que su efectiva inserción en la practica gerencial, está condicionada, entre otros factores, a que se aprenda a lidiar con la variable política, y a que se trabaje ell pro de Cultura, Estructuras Organizacionales, Sistemas de Información Gerencial, Recursos Humanos para el planeamiento. Se apreció, que en la mayoría de las empresas investigadas, la Visión Estratégica cn la Gerencia y especialmcnte en el proceso de planeamicnto es rcciente pero que viene siendo inserida en la filosoFía gerencial gradual y lentamente, ganando cada vez mayor relevancia.

Atratividade e decisão: estudo exploratório sobre a influencia da atratividade no processo decisório em grupo

Esta dissertação girou em torno de um estudo sobre a natureza do desempenho dos grupos em função de algumas variáveis consideradas relevantes. Partindo de pressuposições teóricas que fundamentam o estudo sobre a natureza, origem e funcionamento dos grupos, notadamente Freud, Moreno, Sartre e Lewin e da análise do fenômeno “processo rio em grupo” realizada por Collins e Guetzkow, Oavis e Jay Hall, planejou-se a presente pesquisa que visou analisar o comportamento da variável independente grau de atratividade previa entre os membros de um grupo quando em busca de um consenso. Surpreendentemente os resultados foram completamente discrepantes com as expectativas formuladas. No entanto, pela análise qualitativa e subsequente verificação quantitativa dos dados coletados, tornou-se possível em termos de uma autêntica “serendipity" obter-se um novo e inesperado resultado: ao invés da atratividade ser responsável por uma relativa rigidez ideológica do grupo, constatou-se o alto poder de liberação da criatividade que a atratividade entre os membros exerce. Fator extremamente favorável ao trabalho foi a uniformidade (não esperada) e, inicialmente, não desejada do potencial médio de informações disponíveis, bem como do nível médio de inteligência e da própria performance do grupo. Desta forma, por terem tais fontes de variação se mantidas constante, puderam se converter, na reformulação da pesquisa, em variáveis intervenientes, tornando explicita a dependência do “efeito sinergético” frente ao grau de atratividade.
