Questões contemporâneas sobre natureza e cultura: notas sobre a Saúde Coletiva e a sociologia no Brasil

O presente artigo discute alguns aspectos da relação entre biológico e social, tomando por objeto o campo da Saúde Coletiva no Brasil e o campo das Ciências Sociais, mais especificamente a sociologia. Parte-se do pressuposto de que o conceito que norteia o campo da Saúde Coletiva, o da determinação social (formulado em meados dos anos 1970 e 1980), foi profundamente marcado por certa leitura do social, impregnada dos marcos teóricos clássicos das ciências sociais e marcada pelo cenário político-institucional em que os campos - da Saúde Coletiva e das Ciências Sociais - encontravam-se historicamente. O objetivo é discutir o esgotamento dessa formulação teórica tendo em vista o cenário das profundas mudanças ocorridas nas sociedades contemporâneas em sua etapa industrial tardia, pós-industrial ou tardo-moderna. Acredita-se que a discussão sobre os marcos teóricos constitutivos do campo da Saúde Coletiva contribuirá para um enfrentamento das questões de saúde mais consoante com as mudanças sociais ocorridas.

O Jornal da Paulista: a configuração de um meio de divulgação universitária numa perspectiva histórica

Este artigo, decorrência da pesquisa de mestrado realizada no programa do Centro de Desenvolvimento do Ensino Superior em Saúde da Universidade Federal de São Paulo (2007), tem como objetivo apresentar a descrição e a análise da trajetória histórica do Jornal da Paulista, jornal universitário que surgiu na Escola Paulista de Medicina em 1987 e que circulou até 2003, quando esta já havia se transformado em universidade. Partindo do referencial teórico do semiólogo Eric Landowiski, a trajetória do Jornal da Paulista foi dividida em três fases. Na primeira, o jornal foi compreendido como uma publicação direcionada à necessidade de comunicação interna e de divulgação institucional; na segunda fase ocorreu uma intensificação na publicação de matérias de divulgação científica; e a terceira fase foi avaliada como um momento de envolvimento pleno do jornal com a comunicação pública das ciências da saúde. Apontamos que o JP constituiu-se preponderantemente como um veículo de divulgação científica das ciências da saúde.

Sobre as dores e temores do parto: dimensões de uma escuta

OBJETIVOS: desenvolver algumas reflexões sobre os possíveis efeitos benéficos de uma escuta responsiva à verbalização da presença de dor, medos e seus correlatos na cena do parto tomando como base dados empíricos de pesquisa realizada em maternidade situada na cidade de São Paulo, Brasil. MÉTODOS: estudo descritivo, de metodologia qualitativa, referenciado no quadro teórico da Psicologia Social, Psicanálise e Lingüística, utilizando entrevistas semi-estruturadas com 20 parturientes e sete doulas e observação de rotinas da maternidade. RESULTADOS: a análise, apoiada em categorias estabelecidas (subjetividade auto-referida, intersubjetividade, acolhimento, apropriação da experiência) mostrou, entre outros pontos, a importância e a valorização da interlocução qualificada no processo da parturição. Processo esse referido pelas parturientes como experiência de elevado grau de estresse, com vivências de dor, medos e ansiedades, porém mitigados pelo apoio recebido. CONCLUSÕES: a análise permitiu compreender as relações interpessoais como campo de interlocução e acolhimento percebidos pelas mulheres do estudo capazes de produzir efeitos favoráveis sobre as vivências do estresse materno, configurando-se como recurso técnico, qualificado e valioso, oferecido à parturiente

Contributions of HRM throughout the stages of environmental management: methodological triangulation applied to companies in Brazil

The purpose of this research is to analyze the contribution of human resources management throughout the evolutionary stages of environmental management in Brazilian companies. A theoretical framework concerning environmental management and its evolution and the `greening` of the functional and competitive dimensions of human resource management were developed. A methodological triangulation was developed in two complimentary phases. In the first phase, data were collected from 94 Brazilian companies with ISO 14001 certification. The data collected were analyzed and processed using statistical techniques. The conclusions of the first phase supported the second phase of this empirical research. The second phase consisted of a study of multiple cases in four Brazilian companies. The results show evidence of the first known empirical study of contributions of human resource dimensions throughout the stages of environmental management in Brazilian manufacturing companies.

Evaluation of Characterization and Performance Modeling of Cementitiously Stabilized Layers in the Mechanistic-Empirical Pavement Design Guide

Cementitious stabilization of aggregates and soils is an effective technique to increase the stiffness of base and subbase layers. Furthermore, cementitious bases can improve the fatigue behavior of asphalt surface layers and subgrade rutting over the short and long term. However, it can lead to additional distresses such as shrinkage and fatigue in the stabilized layers. Extensive research has tested these materials experimentally and characterized them; however, very little of this research attempts to correlate the mechanical properties of the stabilized layers with their performance. The Mechanistic Empirical Pavement Design Guide (MEPDG) provides a promising theoretical framework for the modeling of pavements containing cementitiously stabilized materials (CSMs). However, significant improvements are needed to bring the modeling of semirigid pavements in MEPDG to the same level as that of flexible and rigid pavements. Furthermore, the MEPDG does not model CSMs in a manner similar to those for hot-mix asphalt or portland cement concrete materials. As a result, performance gains from stabilized layers are difficult to assess using the MEPDG. The current characterization of CSMs was evaluated and issues with CSM modeling and characterization in the MEPDG were discussed. Addressing these issues will help designers quantify the benefits of stabilization for pavement service life.

Analysis and application of an equilibrium model for in vitro bioassay systems with three components: Receptor, hormone and hormone-binding-protein

A simple theoretical framework is presented for bioassay studies using three component in vitro systems. An equilibrium model is used to derive equations useful for predicting changes in biological response after addition of hormone-binding-protein or as a consequence of increased hormone affinity. Sets of possible solutions for receptor occupancy and binding protein occupancy are found for typical values of receptor and binding protein affinity constants. Unique equilibrium solutions are dictated by the initial condition of total hormone concentration. According to the occupancy theory of drug action, increasing the affinity of a hormone for its receptor will result in a proportional increase in biological potency. However, the three component model predicts that the magnitude of increase in biological potency will be a small fraction of the proportional increase in affinity. With typical initial conditions a two-fold increase in hormone affinity for its receptor is predicted to result in only a 33% increase in biological response. Under the same conditions an Ii-fold increase in hormone affinity for receptor would be needed to produce a two-fold increase in biological potency. Some currently used bioassay systems may be unrecognized three component systems and gross errors in biopotency estimates will result if the effect of binding protein is not calculated. An algorithm derived from the three component model is used to predict changes in biological response after addition of binding protein to in vitro systems. The algorithm is tested by application to a published data set from an experimental study in an in vitro system (Lim et al., 1990, Endocrinology 127, 1287-1291). Predicted changes show good agreement (within 8%) with experimental observations. (C) 1998 Academic Press Limited.

Can I have your attention please: Repressors and enhanced P3 to emotional stimuli

In four experiments ERPs to emotional (negative and positive) and neutral stimuli were examined as a function of participants’ trait anxiety and repressivedefensiveness. The experiments investigated the time course of attentional bias in the processing of such stimuli. Pictures of angry, happy, and neutral faces were used in two of the experiments and pictures ofmutilated, happy, and neutral faces were used in the others. ERP’s to emotional and neutral stimuli were recorded from parietal, temporal, and frontal sites. Analysis of the P3 component indicated that the peak magnitude of the P3 at the parietal and temporal sites reflected an interactive function of trait anxiety and defensiveness. Repressors (low reported anxiety, high defensiveness) showed a consistent pattern of greater P3 magnitude at the parietal and temporal sites for emotional faces (angry, happy, and mutilated) than did high-anxious and low-anxious participants. Participants did not differ in P3 magnitude when ERPs to neutral stimuli were investigated (e.g., a fixation cross). The findings indicate that Repressors dedicate greater processing resources to emotional material, as compared to neutral material, than either the high-anxious or low-anxious individuals. Results of the four experiments are discussed within the theoretical framework of Derakshan and Eysenck (1998). The importance of understanding the role of differences in information processing, in the experience and avoidance of emotional information, as a function of trait anxiety and defensiveness is emphasized.

Searching behaviour and diet of Oystercatcher Haematopus ostralegus pairs feeding in their territories

Search path, searching behaviour and diet of pairs of Oystercatchers feeding in mudflat territories were studied during spring. females ate Nereis, Mya, small unidentified prey, probably Corophium, and a few Macoma, whereas males primarily ate Macoma. Even when female and male foraged in the same site, they often caught different prey. The combination of 'The Search-rate/Detection Model' (Gendron & Staddon 1983) and 'The Harvestable Prey Model' (Zwarts & Wanink 1993) provide the theoretical framework in which to explain these differences in diet. Macoma are thought to be more cryptic than Nereis, Mya and Corophium. Therefore females, while searching at a faster rate than their respective mates, caught far fewer cryptic prey, but a greater number of more conspicuous prey than their mates. On the basis of distances moved before and after capturing prey, males exhibited area-restricted searching for Macoma and Corophium. In contrast, females did not exhibit any area-restricted searching. it is suggested that the distribution of Macoma and Corophium available to males searching slowly was more clumped than that of these two prey species available to females searching more quickly.

Introducing ethnomethodological analysis to the field of music education

In recent years qualitative research methods have been adopted within in the field of music education and have received widespread acceptance. However, the theoretical framework provided by ethnomethodology (Garfinkel, 1974, in R. Turner, Ethnomethodology , Penguin, Middlesex, UK) and the tools of conversational analysis (Sacks, 1992, Lectures on Conversation , edited by Gail Jefferson, Blackwell, Oxford, UK) have, to this point, been overlooked by researchers in the field of music education. In this paper I argue that the application of ethnomethodological and conversation analytical approaches in the field of research in music education can provide fresh insights into the work of music teachers and how this work is accomplished in institutional settings. Here I demonstrate how a conversation analytical perspective drawing on an ethnomethodological framework might be used to investigate transcripts of audio-recorded interview talk. This type of analysis can illuminate aspects of members' roles in relation to, and perceptions about music education in school settings that might be overlooked in other types of analysis. A conversation analytical approach to the examination of talk-in-interaction explicates in fine-grained detail how members orient to matters at hand in the context of research settings, as well as revealing features of the cultural world of music teaching. Further application of the approach to research problems in other school settings, I argue, will inform the field of music education in ways yet to be realised.

The social construction of PETE in higher education: Toward a research agenda

The focus of this paper is the social construction of physical education teacher education (PETE) and its fate within the broader process of curriculum change in the physical activity field. Our task is to map the dimensions of a research program centered on the social construction of the physical activity field and PETE in higher education. Debates in the pages of Quest and elsewhere over the past two decades have highlighted not only the contentious nature of PETE practices and structures but also that PETE is changing. This paper offers one way of making sense of the ongoing process of contestation and struggle through the presentation of a theoretical framework. This framework, primarily drawing upon the work of Lave and Wenger (1991) and Bernstein (1990, 1996), is described before it is used to study the social construction of PETE in Australia. We assess the progress that has been made in developing this research program, and the questions already evident for further developments of a program of study of the physical activity field in higher education.

A general model for host plant selection in phytophagous insects

We develop a general theoretical framework for exploring the host plant selection behaviour of herbivorous insects. This model can be used to address a number of questions, including the evolution of specialists, generalists, preference hierarchies, and learning. We use our model to: (i) demonstrate the consequences of the extent to which the reproductive success of a foraging female is limited by the rate at which they find host plants (host limitation) or the number of eggs they carry (egg limitation); (ii) emphasize the different consequences of variation in behaviour before and after landing on (locating) a host (termed pre- and post-alighting, respectively); (iii) show that, in contrast to previous predictions, learning can be favoured in post-alighting behaviour-in particular, individuals can be selected to concentrate oviposition on an abundant low-quality host, whilst ignoring a rare higher-quality host; (iv) emphasize the importance of interactions between mechanisms in favouring specialization or learning.

Putting the group back into unions: A social psychological contribution to understanding union support

Industrial relations research that attempts to grapple with individuals' union-related sentiments and activities often draws on one of two traditions of psychological research—the individual-level factors tradition (for example, personality and attitude-behaviour relations) and the social context tradition (for example, frustration-aggression and relative deprivation). This paper provides an overview of research conducted from within these traditions to explain union-related phenomena and identifies some of the limitations that arise as a consequence of a shared tendency to treat people in an atomistic fashion. The paper argues for an understanding of the psychological processes that underpin group-based action. To this end, it elaborates a theoretical framework based on social identity theory and self-categorisation theory that would allow us to examine the dynamic interplay between the individual, their cognitions and their environment. The paper concludes with a brief discussion of a specific case of union mobilisation, to indicate how this theoretical framework might aid empirical analysis.

Escolas de governo do cone sul: estudo institucional do INAP (Argentina) e da ENAP (Brasil)

Este estudo analisa o desenvolvimento institucional das experi??ncias de duas escolas de governo - o Instituto Nacional de Administra????o P??blica (INAP), da Argentina, e a Escola Nacional de Administra????o P??blica (ENAP), do Brasil -, que implantaram nos anos oitenta, respectivamente, Programas de Forma????o de Administradores Governamentais e de Especialistas em Pol??ticas P??blicas e Gest??o Governamental. Para tal, ?? utilizado o marco te??rico que se baseia na teoria de institution building e, especialmente, o modelo conceituai de Esman, acrescido de fatores peculiares aos pa??ses estudados. A Ecole Nationale d'Administration (ENA), da Fran??a, modelo de cria????o dessas escolas, ?? analisada como paradigma. Com base no marco te??rico e no modelo franc??s, a an??lise comparativa propicia inferir que tanto o INAP como a ENAP, nos contextos em que foram criados, n??o se institucionalizaram. Al??m do mais, o estudo possibilita identificar e priorizar, como respons??veis por esse insucesso, alguns fatores internos e externos ??s escolas, como a car??ncia de lideran??a, de doutrina, de programa, de recursos e de v??nculos com outras organiza????es e fatores de natureza pol??tico-administrativa e cultural, como clientelismo, corporativismo e descontinuidade administrativa

A educação em cena : a Revista de Educação como circulação de representações sobre saberes educacionais no Espírito Santo (1934-1937)

Este estudo analisa os processos de circulação e apropriação das representações sobre os saberes da educação escolarizada difundidos pela Revista de Educação do Espírito Santo, entre os anos de 1934 e 1937. Como referencial teórico baseamo- nos em Chartier (1990) acerca do conceito de representação, em Balandier (1982) em relação ao conceito de encenação de poder instituído que assume visibilidade quando circula na Revista, concedendo publicização aos feitos políticos realizados por dado grupo social, e em Julia (2001), junto ao conceito de cultura escolar. A partir desse arcabouço teórico, empreendemos metodologia de pesquisa a partir da análise histórica da fonte, dialogando, para tanto, com diferentes documentos e registros que configuram uma série de dados que constituem nossa fonte. Trata-se da análise das representações travadas no debate sobre a formação, divulgação e apropriação do conjunto de práticas e saberes pedagógicos dirigido aos professores, por parte de um grupo de intelectuais locais que se apresentava como portador do projeto de modernização do Espírito Santo inserido no contexto nacional. A Revista de Educação/ES tinha entre seus principais objetivos o de (in)formar os professores, ou seja, enquadrar suas práticas às novas demandas educacionais. Deste modo, a Revista esteve atrelada a um projeto educacional em que os intelectuais corroboravam a ampla circulação de um conjunto de representações sobre a modernidade, utilizando a Revista como suporte, visto que, desde as capas, são expostos “monumentos de modernização”, como os prédios escolares e todo um complexo arranjo de artefatos simbólicos, traduzidos muitas vezes em festas e rituais escolares que evocavam “um novo tempo para a Educação do Estado”, ou seja, fazendo da educação escolarizada um espetáculo.
