This paper, elaborated from documents created and used in the last years by the commissions and coordinations of the Science and Mathematics Teaching CAPES/MEC (Coordination of Improvement of Higher Education Personnel/Ministry of Education) Area, brings some explanations regarding the professional master’s degree in Science and Mathematics Teaching. This kind of master’s program is an innovation in Brazil and may contribute significantly to the improvement of science and mathematics teaching in the country. It may also stimulate the development of similar proposals in other Latin-American countries.

Num contexto de mudanças amplas e céleres nos mundos do trabalho e da cultura, como se situam os professores frente às normas que regulam sua formação? Ao discutirmos esta questão, propomo-nos a colaborar com os debates sobre as políticas públicas, especialmente aquelas diretamente relacionadas à formação de professores de Ciências que atuam em determinada região no interior da Bahia, desvelando fatores que constrangem ou impedem a ação dos professores na configuração dessas políticas e apontando para outras possibilidades de formação docente. Para tanto, utilizamo-nos de dados de pesquisas acadêmicas, documentos, legislação e entrevistas realizadas com 15 docentes. Para a análise, apoiamo-nos em referenciais críticos, particularmente na teoria social de Habermas. Foi possível relevar a ausência do Estado em determinados aspectos da formação desses profissionais, bem como sua presença incisiva e sufocante em outros. A participação restrita dos docentes, como grupo afetado, na produção das políticas de formação demonstra que a integração social não tem se fundamentado na comunicação, mas em processos não linguísticos, principalmente por meio do poder estatal que abriga os ditames do sistema econômico. Finalizamos o texto, chamando a atenção para as possibilidades apresentadas pelo conceito de esfera pública para o apontamento de novas possibilidades formativas.

The concept of educational radio is present in the Brazilian Code of Broadcasting in 1963, valued by an Interministerial 1999.According to the Ministry of Communications, only 176 stations are considered educational universe of 3,000 existing radios in Brazil. In this context, the study proposes to establish a discussion on the educational experiences obtained from the radio, considering the Brazilian radio culture that favors concessions to trade groups and religious politicians. The challenge will be to move toward a program that combines educational content, entertainment, and thus ensures a common universe of communication skills enabling the adult radio listeners their actual interaction with the world around him. The methodology will work in the literature from texts on the subject, and the result of practical observations collected during visits to the broadcasters, programming and analysis.

The creation of the University of São Paulo in the early 1930’s brought about arguments in the projects about its organization. The idea was to establish the Polytechnic School of São Paulo as the core of the future institution. However, the option adopted in 1934 allocated this position to the newly created Faculty of Philosophy, Science and Letters. This caused a strong reaction by both former professional schools that were incorporated into the university, above all the Polytechnic School. This article sets out to describe the conflicts between the Polytechnic School and the Faculty of Philosophy, Science and Letters during the tumultuous beginnings of the University of São Paulo.

Brazil was one of the four countries of Latin America to be elected in this century, the first time a woman for president. But does the fact of having a woman in the highest office of the Republic reflects the reality of women's political participation in Brazil? And how will the female representation in the media of the country? To answer these questions, this article is a literature review of these topics, showing that, despite having a woman in the highest office of the Republic, women's political participation and their representation in the media is lagging behind.

In recent years the availability of equipment for exercise in public places increased demand on the principles of universal design, ergonomics and accessibility, since they are intended for use by many different users. This paper presents an analysis of ergonomic equipment and discusses the main problems observed, as well as projective presents parameters for the development of new products.

In the outline of communication epistemology, the article discusses the fluid and complex delimitations of the field of social communication and its intersections with the world of aesthetics. It includes the question of aesthetic experience and its presence in the epistemological debates on communication in Brazil. It tries to identify possible contributions of the phenomenology of aesthetic experience, based upon the teachings of Mikel Dufrenne and the theoretical references proposed by John Dewey, Paul Valéry, Luigi Pareyson and Jacques Rancière, to the studies on communication. To contextualize the articulations between communication and aesthetics in the debates developed in the Working Group on Communication Epistemology, the article briefly explores the works that discussed that intersection over the last ten years.

Members of the Staphylococcus genus, especially Staphylococcus aureus, are the most common pathogens found in hospitals and in community-acquired infections. Some of their pathogenicity is associated with enzyme and toxin production. Until recently, S. aureus was the most studied species in the genus; however, in last few years, the rise of infections caused by coagulase-negative staphylococci has pointed out the need for further studies on virulence factors that have not yet been completely elucidated so as to better characterize the pathogenic potential of this group of microorganisms. Several staphylococcal species produce enterotoxins, a family of related proteins responsible for many diseases, such as the toxic-shock syndrome, septicemia and food poisoning. To this date, 23 different enterotoxin types have been identified besides toxic-shock syndrome toxin-1 (TSST-1), and they can be divided into five phylogenetic groups. The mechanism of action of these toxins includes superantigen activity and emetic properties, which can lead to biological effects of infection. Various methods can detect genes that encode enterotoxins and their production. Molecular methods are the most frequently used at present. This review article has the objective to describe aspects related to the classification, structure and regulation of enterotoxins and toxic-shock syndrome toxin-1 detection methods.

Milk that is adequate for consumption must be of hygienic quality, nutritional value, and should maintain its organoleptic properties. Isolation of fecal and/or total coliforms from bovine milk is considered an indicator of hygiene and good management practices, and can be used as a quality indicator. This study aimed to isolate, identify, and assess the resistance profile of coliforms isolated from collective bulk tanks and individual milk tanks. A total of 89 milk samples were collected from collective bulk tanks and, from these, 21 Klebsiella spp., one E. coli, and 29 Enterobacter spp. were isolated, whereas 102 milk samples from individual tanks showed isolation of one Klebsiella spp. and seven Enterobacter spp. In collective bulk tanks, at least 47% of Klebsiella spp. and Enterobacter spp. were resistant to cephalexin and 30% to ampicillin. From these, at least 24% showed multidrug resistance. Among the microorganisms isolated from the individual tanks, 85% or more were resistant to ampicillin. The ESBL phenotype and the blaTEM gene were detected in strains of Klebsiella spp. isolated from both tanks. It was concluded that contamination of milk with resistant total coliforms, and especially the storage of raw milk from several small producers in the collective bulk tank increase the risk of contamination.

O presente estudo aborda as relações existentes entre a memória e a arte, registradas atravésde monumentos arquitetônicos na cidade de São Paulo, especialmente, no âmbito da artecontemporânea. Elege como instrumental de pesquisa a história da arte e seus desdobramentosestéticos, tendo como foco de análise a "poética de memórias" de Maria Bonomi uma das mais importantes artistas do cenário nacional. O painel Epopéia Paulista, construído a partirde ateliê-residência, em abril de 2004, no espaço expositivo do Museu de Arte Contemporâneada Universidade de São Paulo (MAC USP) e que hoje se encontra no corredor de ligaçãoentre o Metrô e a Companhia Paulista de Trens Metropolitanos (na Estação da Luz) servecomo obra-referência na criação e no processo de narrativas de memórias de diversas etniasem São Paulo
