Fé e pragmatismo no sertão

Abstract: El imaginario de los “campesinos” es muy impregnado por figuras mistico-miticas que tienen una profunda influencia en la formacion de su ethos social. Folclorificadas o reales, hacen influencia individual y socialmente - aunque no necesariamente consciente de ese poder – en una miriada de “devotos”, en el sentido lato, en el cotidiano representativo de su tierra/identidad: el “campo”. Esta participacion se entrelaza entre diversas corrientes: eclesial, cultural, religioso, transcendental, etc, donde no siempre hacen un dialogo conceptual, fenomenal o institucional o no estan de acuerdo y luchan cuando plantean cuestiones de los dominios de territorialidad religiosas, cuyos lideres y/o portadores de “vinculos sobrenaturales” dictan lo que seguir. Esta influencia es personal o de forma remota, transmitido de generacion en generacion, de manera inculturada o autoctonas y tiene su origen en la Heteronomia, que forjo el imaginario religioso de lo “campesino”. El poder de persuasion es explorado en varias areas desde la politica a la religion, del academico al social, del individuo a las masas. Ha sido canalizado en el trabajo social como para influir en las campanas y mitines electorales; en la identidad del “campesino” a una cultura liquida; en la solidificacion del analfabetismo politico en la educacion contextualizada en regiones semiaridas; una fe esclarecida a una practica religiosa irracional e irresponsable. Este trabajo tiene como objetivo discutir la intima relacion entre estos fenomenos citados manifiesto en calidas demostraciones publicas o en acciones individuales, que constituyen la esencia del “campesino” y sus alrededores.

Chlorine requirement for Japanese laying quails

Abstract: The objective of this study was to determine the chlorine nutritional requirement of Japanese Quails during the laying phase, based on performance and egg quality parameters. A total of 240 Japanese quails were distributed according to a randomized block design, with five treatments and six replicates, with 8 birds each. The experiment lasted 84 days, divided in four cycles of 21 days each. Treatments consisted of a basal diet formulated to meet the nutritional requirements, except for chlorine, and four supplementation levels with ammonium chloride, generating the levels 0.8; 1.6; 2.4; 3.2 and 4.0 g/kg. The parameters evaluated were: feed intake (g/bird/day), egg production (egg/bird/day), egg weight (g), egg mass (g), egg mass conversion (g/g), conversion per dozen eggs (kg/dz), weight of yolk (g/100 g of egg), albumen (g/100g of egg) and shell (g/100 g of egg), specific gravity (g/cm3) and shell thickness (mm). As a result of this study, feed intake, egg weight, weights of albumen, yolk, shell and specific gravity were not affected by treatments. There was a quadratic behavior for egg production, egg mass, egg mass conversion, conversion per dozen eggs and shell thickness according to the chlorine levels in the diets, with the requirements for those parameters established at 1.54; 1.37; 1.39 and 2.78 g/kg, respectively. The recommendation is 1.39 g/kg of chlorine and 244.22 mEq/kg of electrolyte balance in diets for Japanese quails.

Applying optimization algorithms for spatial estimation of travel demand variables

Abstract: Using spatial statistics techniques is a way to improve the forecast of travel demand variables considering their spatial dependence. The semivariogram is a proper geostatistic tool for represent the spatial structure of a Regionalized Variable. Therefore, the semivariogram modeling is a fundamental step and is often done visually, based on data knowledge and researchers’ experience, as well as taking into account automatic criteria, such as weighted least squares function. Moreover, these automatic procedures generally assume that data distribution is Gaussian. This research aims to evaluate the combined use of Genetic Algorithms (GAs) and geostatistical methods to forecast travel demand variables, in order to optimize the calculation and fitting of semivariograms. Car Trip rates and Income by household were estimated using the GA application in variographic models, and therefore enabled us to obtain numerous semivariogram parameters. Consequently, intervals of the most frequent parameters were obtained and those with better performance (based on the fitness value) were chosen to carry out the modeling procedure using geostatistical software. The geostatistical modeling optimization procedure, proposed in this study, was validated considering not only a non spatial model (traditional Linear Regression) but also a different spatial approach, the Geographically Weighted Regression (GWR). The validation was carried out using a bivariate example. Thus, the procedure enabled us to compute and fit semivariograms more accurately, contributing to knowledge about spatial structure and variographic parameters related to almost optimal solutions. It is important to consider that the code developed from this article is available for applications in other knowledge areas with spatial dependence data.

Compromisso e amor como elementos centrais das representações do ser professora de educação infantil

Abstract: Este artigo identifica a estrutura das representacoes sociais que professoras de Educacao Infantil construiram da propria profissao, enfatizando o componente mais forte dessa estrutura: o nucleo central. O referencial orientador da pesquisa foi a abordagem estrutural das representacoes sociais. Representacoes funcionam como guias para as acoes, constituem um sistema de pre-decodificacao da realidade A pesquisa tomou como campo empirico o municipio de Jaboatao dos Guararapes-PE. Participaram do estudo 134 professoras de creches e pre-escolas vinculadas a instituicoes publicas e privadas. O procedimento de coleta utilizado foi a associacao livre de palavras. Para analise das evocacoes utilizou-se software EVOC. Os resultados indicaram como elementos centrais dessa estrutura representacional os termos comprometimento, amor, dedicada, dinamismo, carinhosa, alegria e criatividade. Esses elementos constituem o nucleo estruturador dessa representacao. Pode-se inferir que as professoras tem uma representacao profissionalizada de si e procuram assumir a funcao com compromisso.

Determinação das forças de vínculo em sistemas clássicos holônomos: análise crítica de três métodos

Abstract: Resumo Nesse trabalho, analisamos de maneira critica as peculiaridades e potencialidades de tres abordagens para o calculo das forcas de vinculo em sistemas classicos holonomos, a saber, o formalismo Newtoniano, o formalismo Lagraniano e um terceiro metodo misto desenvolvido pelo fisico brasileiro Nivaldo A Lemos [1] Analisando as solucoes de tres problemas classicos por cada um desses metodos, concluimos que o numero de dimensoes e a quantidade de vinculos do problema influem sobre a eficiencia dos metodos, o que proporcionou o estabelecimento de um criterio para a escolha do formalismo a ser utilizado
