Está bem estabelecida a importância que as deficiências e a suplementação minerais exercem na sanidade, produtividade e economicidade da atividade pecuária brasileira. Apesar de os conhecimentos sobre este assunto no meio acadêmico no Brasil serem sólidos, há numerosos equívocos e crendices sobre a suplementação mineral, aliados à comercialização indiscriminada de suplementos minerais, amplamente aceitos e aplicados no meio rural, o que causa consideráveis prejuízos ao setor pecuário. Neste artigo de interesse geral são discutidos, um por um, as mais importantes interpretações errôneas a respeito desse tema.

Foi realizada uma revisão dos quadros clínico-patológicos causados pelos venenos de Crotalus durissus terrificus e Bothrops spp. em bovinos, búfalos, ovinos equinos e suínos. Foram compilados os dados obtidos pela experimentação em animais de produção encontrados na literatura e os obtidos através de experimentação realizada por nossa equipe. Também foram revisados os casos naturais de envenenamento ofídico comunicados. Em dois Quadros foram lançados os mais importantes dados dessas revisões, que revelou diversos aspectos interessantes: 1) em nossos experimentos, o veneno de Crotalus durissus terrificus, quando injetado por via subcutânea em cavalos, causou um edema acentuado no local da aplicação, ao contrário do que tem sido observado em todas as outras espécies animais, aspecto não relatado na literatura; 2) em nossos experimentos, o veneno de diversas espécies de Bothrops, quando injetado por via subcutânea em bovinos, ovinos e equinos, não causou edema como em geral é relatado na literatura, e sim hemorragias subcutâneas acentuadas no local da aplicação. Nos casos não fatais este sangue era reabsorvido em poucos dias sem deixar sequelas. Exceção foi a reação ao veneno de Bothrops jararacussu, que causou edema nos ovinos experimentais, e tumefação acentuada que resultou em fístula com eliminação de líquido seroso nos equinos experimentais. O objetivo do presente estudo visa contribuir para o aperfeiçoamento do diagnóstico de acidentes ofídicos em animais de produção.

O artigo Teoria Crítica e Administração Escolar procura esclarecer os pressupostos da Teoria Crítica, enquanto método que se opõe ao positivismo e que define objetivos, não apenas de controle da realidade, mas de intervenção e transformação da sociedade, por meio do desvelar dos parâmetros ideológicos presentes no contexto social. Tornando como ponto de partida a Teoria da Ação Comunicativa de Jürgen Habermas, procura discutir a atividade da Administração Escolar como movimento capaz de provocar processos de entendimento e participação coletiva.

This paper brings notes regarding Wittgenstein’s philosophy of language and its presence in habermasian philosophy by means of the basic concept language game. The approach of language of the second Wittgenstein reaches a rather culturalist abstraction, which, however, disclaims him of the pretension of being a theoretical of language, but in Habermas, this approach is put with an intention: the systematization of the universal pragmatics, which he presents as a theory of language games.

Dentro da perspectiva delineada por Jürgen Habermas, que delineia um conceito normativo de esfera pública e de sua importância na democracia, esta pesquisa se propõe a analisar como o jornalismo pode contribuir para a construção da opinião pública, que pressiona os poderes formais. Diante das mudanças nos modos de participação da sociedade civil no poder político, as informações e opiniões relacionadas aos movimentos sociais na imprensa são de extrema importância para a reflexão sobre a democracia. Com o objetivo de entender as contribuições do jornalismo sobre as questões levadas ao público pelos movimentos sociais, este trabalho propõe uma análise do jornal Le Monde Diplomatique Brasil. A partir do método de Análise de Conteúdo proposto por Laurence Bardin, que prioriza a análise qualitativa, a pesquisa busca compreender a constituição e as ideias presentes nos textos e sua relevância para os debates na esfera pública. Desse modo, busca-se apontar pontos positivos e negativos na cobertura jornalística do veículo, que possam contribuir tanto para a prática quanto para os estudos do jornalismo

This study aimed at both identifying possibilities of communicative action that occur in the formative trajectory of Science teachers, and therefore collaborate in the discussion on the rationality approach that supports teacher education. Therefore, we hope to contribute for the construction of a formative model that encourages human emancipation. For this purpose, we draw concepts from Communicative Action Theory proposed by Jürgen Habermas. Data were obtained by half-structuralized interviews. Although strategic actions predominate among those used by teachers during their education period, we observed some tension focus could be identified, better recognized and built up in order to enlarge possibilities of increasing communicative actions in teacher education. We identified political and epistemological factors as obstacles for these possibilities to materialize.

Taking into consideration various argumentation perspectives, the introduction of Modern and Contemporary Physics at High School level has been defended by various researchers. In the present qualitative nature research, we heard and interpreted ten High School physics teachers’ discourses, aiming to analyze how their initial education, regarding to Modern and Contemporary Physics, was based in a rationality which matches with the communicative and the dialogical actions. Teachers of our sample were individually interviewed and, at that time, they had finished their initial undergraduate program at least five years before. Teachers’ discourses interpretation was supported by some French school discourse analysis’ concepts, Jürgen Habermas’ communicative action, Freire’s dialogical action, as well as teachers’ education research critical referential. The discourses interpretations evidenced that these teachers’ education, with respect to Modern and Contemporary Physics, was mainly based in technical-instrumental rationality basis. This perspective did not help teachers’ autonomy construction in order to work these subjects in their classes, mainly in a perspective coherent with the teachers’ emancipation, producing reflexes in classroom physics teaching. The study evidenciates the necessity of future teachers’ professors revise theirs teaching practice, as well studying other curricular structures, regarding to Modern and Contemporary Physics teaching.

This article brings a discussion of the implications of religious diversity on science education as well as on teacher education. To orientate our discussion, we adopt as framework the ideas of German philosopher Jürgen Habermas on the political relationship that should govern relations between a naturalistic culture and different religious cultures. We also present a research with future teachers of physics, which aimed at investigating the positions taken by the future teachers towards non scientific models presented by students about the origins of the universe. We tried to identify, especially, the expectation of these future teachers would demonstrated about the contributing of the lifting of such models in class by students. We were able to find that most of them believe that the manifestation of these ideas could bring contributions to the discussion in the classroom. We also found that teaching practices based on communication, questioning and dialogue of the undergraduate course done by the prospective teachers has generated an ownership by the undergraduates of these practices and their potential application in other situations and other discussions, including inter-religious.

We present in this paper parts of the results of a research that had the intention to promote a space of communicative interaction among teachers of an undergraduate Course of Physics Teaching so they could plan their courses together. From the theoretical recommendations of the Theory of Communicative Action , by Jürgen Habermas , it was possible to draw a way of rationality crisis in training degree in physics in Brazil and then propose the creation of a Joint Planning Group (JPG) with teachers of specific nature disciplines of physics and disciplines about physics teaching. They start a joint discussion about the relationship among the disciplines in delivering of a project for future high school teachers' training. All meetings developed over a school year in the GPC were recorded, transcribed and analyzed with a part of a methodological analysis feature of the intersubjective interactions. This methodology was developed specifically for the research. The conclusions are related to the joint constructions developed by the JPG, its local contexts and the possibility of extension of this group. The joint constructions undertaken in the group point to the defense of the formation of JPG in the formation of the professors who teach these courses.

The internet is fast becoming a means for people to obtain information, creating a unique forum for the intersection of the public, technical, and private spheres. To ground my research theoretically, I used Jürgen Habermas’s sphere theory. Habermas (1987) explains that the technical sphere colonizes the private sphere, which decreases democratic potential. In particular, the internet is a place for altering technical colonization of the private and public spheres. My research focuses on women’s health because it is a particularly useful case study for examining sphere tensions. Historically, the biomedical health establishment has been a powerful agent of colonization, resulting in detrimental effects for women and their health. The purpose of this study is to examine how the internet encourages expert and female patient deliberation, which empowers women to challenge the experts and, thus, make conversations between the private/technical spheres more democratic. I used PCOS (Polycystic Ovarian Syndrome) as a case to observe the changing sphere boundaries by studying the discourse that took place on multiple patient and doctor websites over a four-year period. Through my research, I found that the PCOS women challenge the biomedical model by appropriating medical language. By understanding the medical talk, the women are able to feel confident when discussing their health conditions with the doctor and with each other. The PCOS women also become lay-experts who have personal and medical experience with PCOS, reducing private sphere colonization. This case study exemplifies how female empowerment can influence expert culture, challenging our conventional understanding of democracy.

A política para Jürgen Habermas se faz com a formação de consciências e com o investimento na linguagem, no falar cotidiano, na relação intersubjetiva. Já para Niklas Luhmann, a política se faz por si mesma, e a opinião pública não tem relação com a opinião pessoal. Não adianta investir na linguagem, porque ela é pré-social, está além dos sujeitos, nenhuma democratização pode sair daí. Mas as propostas dos dois pensadores mostram-se insuficientes para a atualidade, com suas altas tecnologias comunicacionais, pois nenhum dos modelos dá uma resposta animadora para a questão das redes, nenhuma delas visualiza um espaço mediático próprio fazendo a mediação dos sistemas, nenhuma delas dá elementos para a construção de uma teoria da comunicação tecnologicamente avançada.
