Water-contact patterns and schistosoma mansoni infection in a rural community in northeast Brazil

We evaluated the influence of water-related human activities, contaminative behaviour, house location, education and socio-economic status on endemic Schistosoma mansoni infection. The study was conducted in a hilry non-irrigated area of rural northeast Brazil amongst a defined population of subsistence farmers, of whom 93% were infected by age 20. The area was mapped, water bodies were surveyed, and a detailed questionnaire was performed on each household. Infection was assessed by duplicate stool examinations using the sensitive Bell technique to quantify egg excretion. For each household, and index of intensity of infection was computed by grouping individual log-transformed egg counts as an age-sex adjusted Z score. Few households had a sanitary installation or a domestic water supply. However, neither water-contact nor contaminative behavior were indiscriminate. The people made considerable effort to defaecate far from a water source, to obtain household drinking water from the cleanest source, and to bathe only at certain sites where privacy is assured. Land ownership and literacy correlated poorly with the household index of intensity of infection. The key influence on infection status was the relative location of the house and snail-free or snail colonized water sources. In this area, a safe domestic water supply is the critical input needed to achieve definitive control of endemic Schistosomiasis.

Addressing conflicts of interest in the research paper: a societal demand in contemporary science?

In the last decade, dialogue between science and society has found a forum in an increasing number of publications on topics such as public engagement with science and public trust in science. Concerning the latter, issues that include cases of research misconduct, accountability in research, and conflicts of interest (COIs) have shaped global discussions on the communication of science. In the publication setting, the perception that hiding COIs and/or not managing them well may affect public trust in the research record has grown among editors. We conducted a search for editorials addressing COIs between 1989 and 2011, using four major databases: Medline/PubMed, Embase, Scopus, and Web of Knowledge. We explored the content of these editorials and the relationship they established between COIs and the public trust in science. Our results demonstrate that the relationship between disclosure of COIs and public trust in science has become a major concern among editors. We, thus, argue that COIs should be discussed more openly and frequently in graduate courses in the sciences, around the globe, not only in biomedical but also in non-biomedical areas. This is a critical issue in contemporary science, as graduate students are the future voices and decision-makers of the research community. Therefore, COIs, especially in the broader context of science and society, merit closer attention from policymakers, researchers, and educators. At times of great expectations for public engagement with science, mishandling of COIs may have undesirable consequences for public engagement with science and confidence in the scientific endeavor.

Aplicação da geotecnologia no estudo de cadastro técnico rural e no mapeamento de áreas de preservação permanente e reservas legais

Este trabalho teve como objetivo principal mapear as classes de cobertura e o uso da terra, bem como as áreas de preservação permanente (APPs) e de reservas legais de imóveis rurais. A área de estudo compreendeu parte dos municípios de Canaã, Araponga e Ervália, Estado de Minas Gerais. Foi utilizada uma imagem ortorretificada de alta resolução do sensor Ikonos II com 1 m de resolução espacial. A partir da interpretação visual da imagem, foram criadas sete classes temáticas, a saber: cobertura florestal, pasto sujo, pasto limpo, cafezal, edificações, área agrícola e reflorestamento. As APPs foram obtidas a partir de um modelo digital de elevação hidrologicamente consistente. Os resultados mostraram a predominância das classes de cafezal com 24,5% e de cobertura florestal com 28,8%, perfazendo mais de 50% da área de estudo. As áreas delimitadas como de preservação permanente totalizaram 55,1%.

Diferenças entre os gêneros na assistência técnica e extensão rural realizada por médicos veterinários: paradigma ou preconceito

A Medicina Veterinária é profissão relativamente antiga e, mesmo em tempos modernos, em determinados países ou regiões, a profisssional veterinária ainda encontra barreiras ao exercício pleno da profissão, tanto nas atividades de Assistência Técnica como nas de Extensão Rural. Este estudo objetivou verificar se existem diferenças entre os gêneros, no que se refere às atividades de Assistência Técnica e de Extensão Rural, realizadas por médicos veterinários no Estado de Goiás (Brasil) e, em caso de existência, analisar se os resultados podem ser considerados frutos de um paradigma ou de preconceito. O trabalho foi desenvolvido no Estado de Goiás, em 26 municípios, envolvendo 100 propriedades rurais, administradas por indivíduos de diferentes gêneros e perfis. Foram analisados questionários respondidos pelos proprietários, envolvendo cinco temas, compreendendo diferenças entre os gêneros, senso de organização profissional, relacionamento interpessoal, força física e conhecimento técnico. Na visão dos entrevistados, os homens foram considerados como detentores de maior aptidão para as atividades que exigem força física e, as mulheres, para o trabalho que requer maior senso de organização. Para as outras atividades, ambos os profissionais equipararam-se quanto ao seu desempenho, pois a maioria dos entrevistados alegou não ter preferência, em relação aos aspectos gênero, relacionamento interpessoal e conhecimento teórico. Concluiu-se que as diferenças entre os gêneros, nos desempemhos em Assistência Técnica e em Extensão Rural, realizadas por médicos veterinários no Estado de Goiás, foram identificadas quando os aspectos considerados são a força física e o senso de organização. Nos quesitos preferência pelo homem ou pela mulher, relacionamento interpessoal e conhecimento técnico, não houve distinções. Dessa forma, pode-se considerar a existência de um paradigma, não a de um preconceito.

Satisfacción con el empleo de extensionista rural: un estudio cualitativo en Caldas, Colombia

Como aporte al posicionamiento de la extensión rural como objeto multidimensional de estudio, se analizan las valoraciones realizadas por extensionistas rurales acerca de situaciones inherentes a su experiencia cotidiana de trabajo, seguido de la identificación de factores de satisfacción/insatisfacción laboral. En consonancia con la esencia cualitativa del estudio, la información se generó a partir de entrevistas semiestructuradas a 23 extensionistas rurales adscritos las Unidades Municipales de Asistencia Técnica (UMATA) de cinco municipios del departamento de Caldas, Colombia. El análisis de discurso permitió identificar ocho factores: a) gusto por la profesión ejercida, b) posibilidades de proyección social, c) alcance y visualización de logros, d) reconocimiento público, e) posibilidades de ascenso, f) posibilidades de aprendizaje continuo, g) autonomía, y h) estabilidad laboral. Se concluye que desconocer el estado emocional de los extensionistas hacia el trabajo produce el riesgo de crear o conservar escenarios que limiten el compromiso con la labor social realizada y el mantenimiento de la vocación extensionista.

Contemporary issues in the government and administration of Latin American megacities

This paper is the first to systematically analyze and compare the structures of city governance and administration for seven major cities in Latin America, four of which are megacities (population of over 10 million), and three others are large national capitals. U.S. and U. K. models of city administration are reviewed as baseline models against which differences in Latin American may be explored. Structures of Government in Latin America show several important features and trends: 1) the lack of metropolitan (cross jurisdictional) authority; 2) the existence of strong mayors and weak councils"; 3) high levels of partisanship; 4) overlapping rather than interlocking bureaucracies; 5) pressures towards the privatization of city services, but continuing tension over the desirability of public versus private control; 6) greater fiscal responsibility and autonomy; and 7), a continuing marginalization of public participation in megacity governance.In spite of these features, many cities throughout the region (regardless of whether they are megacity size or national capitals), are actively intensifying their efforts to develop more effective, accountable and democratic governance structures.

Neoinstitutionalism and the appropriation of bourdieu's work: a critical assessment

Despite the still present hegemony of the structural-functionalist orthodoxy, the mid 1980's witnesses the insurgence of new philosophical approaches. This body of work had become a vital intellectual and ideological resource for those who wanted to confront the functionalist dominance in organization studies, such as structuration theory, labour process theory and neoinstitutionalist theory. The purpose of this paper is to review the incorporation of Bourdieu's work into neoinstitutionalism. I argue that this appropriation has resulted in a significant loss of theoretical strength. By giving place to the cognitivist metaphors of mental models, "scripts" and "schemas", instead of adopting the notion of habitus, neoinstitutionalism reinforces some of the ever-present dichotomies in social sciences, especially those of agency/structure and individual/society. While neoinstitutionalism was refining the cognitive approach in the 1990's, Bourdieu was moving towards psychoanalysis. Some indications for future research are provided in the concluding notes.

Dependence relationship between the critical quality factors and social impact

This paper shows the results of the empirical study conducted in 186 tourist accommodation businesses in Spain certified under the "Q for Tourist Quality", own System Quality Management. It was raised with the purpose of analyzing the structure of the relationship between critical quality factors and results-social impact, how they operate and the level of their influence on obtaining these results within the company. Starting from a deep theoretical revision we propose a theoretical model together with the hypotheses to be tested, and we proceed to validation using the technique of Structural Equation Models. The results obtained show that companies wishing to improve their social impact should take into account that leadership is the most important factor to achieve it. Leadership indirectly affects the social impact through its influence on alliances and resources, quality policy/planning, personnel management and learning.

AN ANTI-MANAGEMENT STATEMENT IN DIALOGUE WITH CRITICAL BRAZILIAN AUTHORS

The expressions Management and Organization Studies and Management and Organization Knowledge are expressions of an Anglo-Saxon construct. The association of Organization Studies (OS) with Management (M) produces the subordination of the former to the latter. In a different direction, a critical approach elaborated in Brazilian OS provides an original body of knowledge that expresses an anti-management (A-M) attitude. As the Brazilian A-M authors point out, the distinction between North/South M is irrelevant; what is relevant is a coherent pluriversal A-M attitude. In this paper, we honor and disseminate the Brazilian original body of knowledge on OS and introduce an OS agenda that is liberated from M.
