Composição fotojornalística e história: função testemunhal como ato performativo e interação de linguagens

Assuming that testimony in photojournalism must be understood as a historical and performative act, the aim of this article is to discuss how the testimonial function of journalistic photography was constantly re-signified in Brazilian news magazines during the twentieth century. This redefinition has a relation with the different ways in which testimonial function was hinged to news report (in its broadest elements) and how this imperative appeared on its discursive form in writing narrative. As trustee of a narrative intended to be realistic, photojournalism articulates, from techniques and codes of narration, a series of referential and informational strategies. These strategies, however, have changed over time, based on different modes of narration by image and its accreditation in reality.

Aplicação de métodos ergonômicos na avaliação de ferramentas produzidas e utilizadas por homens na Pré-História

The study of prehistoric artifacts may contribute to understand the development of these artifacts, and also of ergonomics. This study aims to investigate and identify the types of grips of two Brazilian stone tools (scraper / piercer and a slug) approximately 5000 years old through the use of gloves with sensors and contact maps of the hand palm, exploring the best method for research of ergonomics in prehistory. Hence it can contribute to the discussion of a part of the ergonomics’ history that remains underexplored.

Descrever o passado para prever o futuro: sobre os usos da história no jornalismo para o delineamento de prognósticos

Once the use of historical data serves as an articulator of senses in journalistic narratives, this article proposes to study the cases in which the discursive constructions of the future are structured from the evocation of the past. It is possible to discern how images of the future built on stories parting from the past is related to a specific conception of history and how this history is seen, by journalism, as a repository of examples enrolled in a temporal continuum and fixed as a judging instance able to measure and anticipate the future consequences.

Eletrocardiograma em cães: revisão

The electrocardiogram (ECG) is an important tool used in the diagnosis of cardiac arrhythmias, since it gives the graphic representation of depolarization and repolarization processes of the cardiac muscle. This study allows recording the electrical activity of myocardial cells and the underlying differences in electric potential: the magnitude of this difference is measured in millivolts (mV), and its duration is measured in seconds. The ECG is indicated when an irregular rhythm is detected during physical examination, such as bradycardias, tachycardias or arrhythmias that are not secondary to breathing, in animals with a history of syncope or weakness, for monitoring the effectiveness of antiarrhythmic therapy, in cases of putative pleural or pericardial effusion, and also in systemic diseases that lead to arrhythmia. For a reliable assessment, the ECG must be evaluated in conjunction with findings from the physical examination and clinical signs of each patient.

Titia vem cá ver a pedra alumiante que o papai trouxe'. História da Ciência, Radioatividade e o Césio-137 em Goiânia: propostas para uma unidade didática

This study aimed to discuss the recent contributions of History of Science to theteaching of chemistry. The theme of the teaching unit was on the accident of cesium-137 in Goiânia ? Goiás, Brazil (1987). This was a qualitative study in which researcherand professor use the methodology of teaching on research. Thus, students should seekinformation, organize the data collected and establish relationships. Students producedposters in an exhibition at the school on the twentieth anniversary of the accident.Results demonstrated the importance of this resource. It was possible to exploit theabundance of detail and illustrations utilized what themes they students considerimportant and which they exploited.

The study alsorevealed the importance of using elements of the History of Science in ChemicalEducation and its relationship to the daily life of students.Key words: history of science; radioactivity; cesium-137

Economia política da arte moderna/providências para uma história crítica

Este texto, a ser publicado em duas partes, contém, com pequenas modificações para efeito de edição, extratos da introdução e da conclusão da tese de doutorado A fabricação da pintura: de Manet a Rothko, defendida no Departamento de Filosofia, FFLCH-USP, sob orientação do Prof. Dr. Paulo Arantes em 2000. Opondo-se à visão hegemônica propagada pelas correntes formalistas, cujas motivações ideológicas pretende explicitar, o ensaio salienta a valorização dos processos produtivos frente às obras acabadas como característica fundamental da arte moderna, característica por meio da qual os artistas resistem ao progresso da modernização capitalista

Uma história de conceitos na saúde pública: integralidade, coordenação, descentralização, regionalização e universalidade

O Sistema Único de Saúde conferiu visibilidade a uma série de conceitos próprios da organização de sistemas de saúde. Entre eles a integralidade, que delimita fronteiras comuns com quase todos os demais princípios do Sistema, tem sido objeto de ampla literatura no Brasil. Com base em extensa revisão de fontes primárias e secundárias, este artigo apresenta uma recuperação histórica dos conceitos de integralidade, descentralização, regionalização e universalidade - ideias e conceitos que em grande parte se conformam e se interligam no ideário da organização dos serviços sanitários pelo modelo dos Centros de Saúde distritais.
