O trabalho investiga os projetos editoriais e gráficos da Folha de S. Paulo produzidos desde a década de 1970, de modo a tentar compreender a evolução histórica recente do veículo, além do amadurecimento de seu conceito de jornalismo e de sua visão como empresa, os quais o alçaram à condição de jornal mais importante do país, posição que raramente perdeu e ainda mantém. Com ferramentas metodológicas emprestadas de Mikhail Bakhtin, a autora demonstra que, apesar das estabilidades estruturais desse jornal enquanto gênero discursivo se ampararem em elementos como conteúdo temático, traços formais e estilo verbal, esses mesmos elementos seriam sutilmente transformados ao longo dos anos, de modo a adaptar continuamente o veículo ao universo mutável que o circunda, constituído pelos leitores, anunciantes, governos, o desenvolvimento tecnológico e o próprio conceito de jornalismo. A pesquisadora mostra o quanto a Folha de S. Paulo precisou se modificar para enfrentar a concorrência dos outros jornais, da televisão e, em especial, da internet, que impôs um novo tipo de tratamento à informação. E como, nesse percurso, o jornal conseguiu consolidar sua visão de mundo e sua noção particular de informação como mercadoria

O advento de uma nova ordem global mediada pelas tecnologias de informação e comunicação pode parecer, a um observador desatento, algo bom ou, no mínimo, neutro. No entanto, os valores decorrentes deste modelo organizacional estão intimamente ligados a interesses políticos, econômicos e ideológicos. Entender a complexidade dessa nova dinâmica em nossas vidas, sem cair nos extremismos da questão, é o desafio a que nos propomos. Para tanto, discutiremos no primeiro a relação entre tecnologia e sociedade desde o advento do alfabeto ocidental. No segundo capítulo apresentaremos os fundamentos da análise do discurso de linha francesa e, no terceiro capítulo, analisaremos os cadernos de informática do mês de agosto de dois grandes jornais impressos brasileiros – Folha e Estado de São Paulo - à luz das teorias da análise do discurso, buscando entender como a construção simbólica de nosso atual contexto se manifesta na forma discursiva do jornalismo

The work aims to analyse the concept of economics as the science of scarcity is distorced in the newspaper Folha de Sao Paulo. Neoclassical economists characterize the economy as the science that is concerned with the welfare of the people, satisfying their needs. However, the economy in the newspapers of the mainstream media appears in contexts where only the profit of companies and businesses are addressed, leaving aside the problem of economic inequality, unemployment, working conditions and other issues that are also part of economy, but they are hardly concerns of journalists. In this work, the object of study was the notebook Market and content analysis followed the criteria of Bardin (1977). Ten words were chosen in the category science of scarcity and ten words were chosen in the category science of abundance. From these categories, a careful reading was done, counting how many times each word appeared in the newspaper. Also paid attention to the words that appeared and contexts in which they fell journalistic genre. In a second step, interviews were conducted with journalists from economics to know what they mean by the economy and what the guidelines are more common. Data collection and interviews contributed to the interpretation and confirmation on whether or not the distortion of the concept of economy and how it happens

This study aimed the geological characterization at scale 1:50.000 of an area belonging to the southern sector of the Brasilia Belt, located in the western portion of the Passos Nappe, near the town of Cássia, MG. In this region, outcrops rock types belonging to Araxá Group, composed of metasediments associated with metavolcanics which form a tectonometamorphic terrain of great importance for understanding the geological evolution of southeast and midwest regions of Brazil. With the development of work was possible to group the rocks in 10 lithostratigraphic units and had been identified 3 different zones of metamorphism generated during the peak metamorphism. The structural pattern of the area shows that the main foliation has average dip 30 ° NW and mineral lineation parallel to the stretching direction with 290 °. Still, we can conf irm that this inverse gradient metamorphic rocks of the Passos Nappe, described by several authors. Also, were seen lithotypes of economic interest, some already in exploitation, such as clay and sand, and other mineral commodities, which are occurring and can be used: quartz, quartzite, garnet, kyanite, rutile and zircon.

This study aims to discuss the social media presence of the Brazilian newspapers Estadão and Folha de São Paulo, and how both have been working their way of communication on Facebook, the world famous social network. This study conducts a theoretical and conceptual review on the social media field and the digital media tendencies of journalism. It is also pointed out how the fanpages development was conceived -- recently, these fanpages have been aiming to find a way to approach their readers and interact with them. How both newspapers found a brand-new model on their social networks and how this model contributed to a more participative and equal communication, which involves the social network users, are worth of mention goals in this research

The comet assay is a method of DNA damage analysis widely used to quantify oxidative damage, crosslinks of DNA, apoptosis and genotoxicity of chemicals substances as chemical, pharmaceuticals, agrochemicals products, among others. This technique is suitable to detect DNA strand breaks, alkali-labile sites and incomplete excision repair sites and is based on the migration of DNA fragments by microeletroforesis, DNA migrates for the anode forming a “tail”, and the formed image has the appearance of a comet. The slides can be stained with fluorescence or silver, having differences in the microscopy type used for the analysis and the possibility of storage of the slides, moreover, the first one is a stained-method with more difficulties of accomplishment. The image analysis can be performed by a visual way, however, there is a disadvantage as the subjectivity on the results, that can be minimized by an automated method of digital analysis. This process was studied in this report with the aim to perceive the validation of the digital analysis turning it a quantitative method with larger reproductibility, minimizing the variability and imprecision due to the subjective analysis. For this validation we selected 50 comets photographed in a standardized way and printed, afterwards, pictures were submitted to three experienced appraisers, who quantified them manually. Later, the images were processed by free software ImageJ 1.38x, printed and quantified manually by the same appraisers. The intraclass correlation was higher to comet measures after image processing. Following, an algorithm of automated digital analysis from the measures of the comet was developed; the values obtained were compared with those 12 estimated manually after the processing resulting high correlation among the measures. The use of image analysis systems increases ...(Complete abstract click electronic access below)

Este trabalho tem por objetivo investigar quais são os mecanismos que permitem a produção de identidade pela mídia e discutir como ela é um dos principais pólos produtores da identidade na sociedade. Para tanto, serão estudadas as matérias e artigos veiculados pelos jornais O Estado de S. Paulo e Folha de S. Paulo sobre os futebolistas Kaká e Adriano, comparando como a identidade de ambos foi construída por esses meios e pelo contexto desempenhado pelo futebol na sociedade. A escolha dos dois jogadores se deve à ampla cobertura dada sobre Adriano quanto a sua possível ligação com o tráfico no Rio de Janeiro, enquanto a cobertura sobre Kaká foi mais apagada em relação à possível utilização da Igreja Renascer em Cristo para lavagem de dinheiro. Nesse procedimento, estaremos apoiados nas formulações teóricas de Laurence Bardin, em Análise de Conteúdo

The objective of this paper is to discuss the construction of the image of São Paulo state public schools teachers in the public sphere, by the media and the trade union press, and see how that image is formed in both of them, without making any comparisons, from the covering of 2010 strikes by newspapers Folha de S. Paulo and Jornal da Apeoesp. This paper uses as theoretical basis the study of Media Hegemony, the concept of Radical Media and Public Sphere, as well as the relationship between them and social movements. It also considers the observation of the history and characteristics of trade union press and the Standards of Manipulation by the Press, proposed by Perseu Abramo. The chosen method was the identification, selection and organization of stories about education published by Folha de S. Paulo during the period; the application of Abramo’s proposed manipulation standards on the stories about the strike; research, selection and observation of print publications (Jornal da Apeoesp and newsletters Apeoesp Urgente) about the strike, published by Apeoesp during the same period

Silver nanoparticles (Ag) were deposited on multi-walled carbon nanotube by eletroless. The hybrid Ag/MWCNT was used in the modification of glassy carbon electrode (GC) surface. The electrochemical characterization confirmed the presence of Ag in the nanocomposite has been showed that the synthesis was successful. The GC electrode modified with Ag/MWCNT film was evaluated for electro-oxidation of benzene. The electrochemical behavior presented an improvement on the catalytic surface in relation to non-modified GC electrode. The anodic peak current increased the magnitude in three times when compared with the CG electrode modified only with MWCNT
