Casal nacional: significações do corpo e do figurino no telejornalismo

The main objective of this study is to investigate the meanings of body and costume as essential components of television journalists aesthetic discourse, as exemplified by the presenters of Jornal Nacional, from Rede Globo. The study is inspired on the paths proposed by semiotics, and combines this approach with other techniques of scientific investigation to identify the meanings of this non-verbal communication form. For that, this work uses the concept of communication proposed by the Palo Alto School s authors, more specifically the concept of Watzlawick et al. (2005), which understands communication like relation and inherent of human beings. The precepts of complex thought and the hologramatic principle of Morin (1990), which value the union and the need to connect the knowledge of elements or parts to that of the systems these parts constitute, is also present in the thinking that guides the work. Throughout the chapters, we elucidate our understanding of body and television as media, and fashion and television journalism as languages. This work approaches a televisual history of Jornal Nacional in order to better understand the aesthetic proposed by television news over time, its presenters and costumes. The elements that are part of the televisual language s expression and content are addressed so that we can better understand the importance of body and presenters costume in this context. Finally, we conduct an analysis of the meanings of television journalism presenters body and costume through their stereotypes, their integration into the fashion cycle and also into the televisual analysis of the most important costume elements of Jornal Nacional s presenter couple: colors, models and accessories. We thus seek to strengthen the understanding of the wardrobe inseparable from the body as communication and detail some of their production understanding processes. The women historical role in brazilian television journalism, as well as masculinization of TV journalism environment are important elements to contextualize televisual language thinking in contemporary society. The investigation covers the origins, concepts, proposals, stereotypes, prejudices, reproductions, naturalizations and reinterpretation of the body and the costume of the presenters through time and the relationship between body, fashion and communication

Estratégias midiáticas na aprendizagem do tema DST/AIDS: ações em rede para reduzir vulnerabilidades de adolescentes e jovens da comunidade de Mãe Luiza, Natal-RN

Youngsters and teenagers are still a very vulnerable group of DST/AIDS. In order to combat this vulnerability the community intervention project being developed in Mãe Luiza neighborhood in the city of Natal-RN, entitled Strengthening Community Action Network for Prevention in HIV/AIDS: knowledge and Intervene emerged, popularly known as Project Viva Mãe Luiza. The project develops workshops of educomunication whose approach involves the DST/AIDS subject with the following media: video, photography, and theater playbook. This research integrates the activities of the project and has as main objective to investigate how strategies and practices of media communication developed in Project Viva Mãe Luiza through workshops of educomunication, assisted learning for the prevention of DST/AIDS and contributed to the reduction of vulnerability to DST/AIDS among adolescents and young participants of the project residents of Mãe Luiza community. The methodological basis was based on intervention research, with the technique of gathering daily field data, literature and documentary, in-depth interviews and ethnographic observation. The qualitative analysis was based on the monitoring of video workshops, photography, theater and primer, respectively, crossed by transverse to the prevention of DST/AIDS, conducted between June 2012 and December 2013 issues. Interviews with eight multipliers, aiming to understand their perceptions of vulnerability, prevention, multiplication and use of media that were part of the project were conducted. The analyzes show that learning workshops educomunication community health repercussions both in the development of individual skills in communication as changing perceptions about the vulnerabilities to which they are exposed, the awareness about prevention at the individual and differentiated actions multiplication in the community

DFT study of alpha-alanine as a function of the medium polarity

The zwitterionic (Z) form, neutral (N) form and transition structure (TS) connecting N to Z, have been studied at the B3LYP/6-31++G** level of calculation by using the SCRF methodology. The intramolecular proton transfer from oxygen to nitrogen atoms of alpha -alanine and vibrational spectrum were analyzed in the different environments employed: acetonitrile, ethanol, carbon tetrachloride and gas phase. The Z species is a stationary point in acetonitrile and ethanol, but not in carbon tetrachloride and gas phase media. The geometry of N, Z and TS was similar in acetonitrile and ethanol. The vibrational spectrum of Z was similar in the two solvents studied. (C) 2001 Elsevier B.V. B.V. All lights reserved.

Adolescentes preocupadas em conquistar um corpo magro: Um estudo sobre discursos produzidos em diários eletrônicos

The concern about a good physical condition is heavily present nowadays, in documentary films about health and in the media, and it is also expressed through the outstanding growth of physical academies, beauty institutes and aesthetic medicine and all kind of aesthetic surgeries. In the western world the body wave is a significant trend, characterized by the great investments in body image. However, what is overlooked is the fact that in parallel trend grows the number of teenagers, especially females, with all kind of problems related to their body image. As adolescence is a moment of transformations, teenagers tend to be more aware of their body image and often neglect food ingestion and try to build their bodies following the images they have from top models and movie stars. The low self-esteem accompanying this sort of experience is an additional problem. Therefore the research aim to analyze discourses regarding the body image produced in world wide web diaries (blogs). The blogs selection was made through the site www.blogs.com.br, which is considered the widest guide of electronic diaries in Brazil. We looked after blogs including the keyword body and from adolescents aged 10 to 19, who showed concern about a slim body. Three blogs were chosen, considering the example criteria. Discourse analysis shows that these teenagers feel unsatisfied with their bodies, searching by all means the thinness presented as a aesthetic paradigm in western societies which often implies neglecting their own health, using appetite inhibitor drugs, restricting or totally abstaining food ingestion for long periods of time, or provoking themselves vomits after ingesting food. These behaviors, together with intense fear of gaining weight, can be characterized as alimentary disorders, related to the body image. As they usually hide this sort of behaviors from family and friends who do not share this concern, the blogs seem to be an easy tool for adolescents to find peers with whom to share common values and ideas and reaffirm their identities and virtual sense of community

Estudo do equilíbrio e cinética de adsorção de um corante aniônico em quitosana

The phenomenon of adsorption is of fundamental importance for the treatment of textile effluents and removal of dyes. Chitosan is characterized as an excellent adsorbent material, not only for its adsorption capacity but also the low cost production. Equilibrium and kinetic studies were developed in this study to describe the mechanism of adsorption of the anionic azo dye Orange G in chitosan, with the isotherms obtained from the variation of the concentration of dye in the continuous phase. The kinetics of the process was analyzed based on models involving the adsorption of molecules of the dye in nonpolar and polar sites. Adsorption experiments were carried out in water and in saline media with different NaCl concentrations, both for the determination of the equilibrium time as isotherms for making kinetic curves in which the amount of dye adsorbed measured indirectly varied with time. The experiments revealed the opening of the biopolymer structure with increasing concentration of Orange G, accompanied by high pH values and change on the type of interaction between the dye and the adsorbent surface, suggesting behavior advocated by the Langmuir equation in a certain range of concentration of the adsorbate and following the Henry's Law at higher concentrations, from the increased number of sites available for adsorption. The studies conducted showed that the saline medium reduces the chitosan s adsorption capacity according to a certain concentration, the occurrence of the cooperative adsorption process steps kinetic mechanism suggested as a new alternative for the interpretation of the phenomenon

MARISA-MDD: uma abordagem para transformações entre modelos orientados a aspectos: dos requisitos ao projeto detalhado

Aspect Oriented approaches associated to different activities of the software development process are, in general, independent and their models and artifacts are not aligned and inserted in a coherent process. In the model driven development, the various models and the correspondence between them are rigorously specified. With the integration of aspect oriented software development (DSOA) and model driven development (MDD) it is possible to automatically propagate models from one activity to another, avoiding the loss of information and important decisions established in each activity. This work presents MARISA-MDD, a strategy based on models that integrate aspect-oriented requirements, architecture and detailed design, using the languages AOV-graph, AspectualACME and aSideML, respectively. MARISA-MDD defines, for each activity, representative models (and corresponding metamodels) and a number of transformations between the models of each language. These transformations have been specified and implemented in ATL (Atlas Definition Language), in the Eclipse environment. MARISA-MDD allows the automatic propagation between AOV-graph, AspectualACME, and aSideML models. To validate the proposed approach two case studies, the Health Watcher and the Mobile Media have been used in the MARISA-MDD environment for the automatic generation of AspectualACME and aSideML models, from the AOV-graph model

Experiências de inverno no seridó potiguar

The knowledge known as "winter experiences" has been developed for centuries among country people in the Brazilian Northeast hinterlands. It consists in the systematic observation of the nature to forecast and protect people against the effects of droughts. This knowledge is transmitted orally through generations. These experiences are guided by the observation of the behavior of fauna, flora, stars, the weather in the holy days and other very specific aspects of the lives of country people. Almost all country people living in the rural area know at least one experience, but the Prophets of Rain are known as the communicators of winter prophecies formulated from the observation of the experiences. The country person is identified as a Prophet of Rain because of his close relationship with nature and his ability to forecast. No matter if the prophecies are always right, he possesses a vital social role, as his practices contribute to prevent, ease and encourage other people. The main aim of this work is to analyze the role of the winter experiences for the country people in the Seridó Potiguar. In this sense, we sought to understand to what extent this knowledge still orients the productive practices of farmers living in this region and identify which factors instigate the observation of winter experiences nowadays. 241 questionnaires were applied to farmers in the rural cities of Acari, Caicó, Parelhas and Lagoa Nova and interviews were conducted with 15 Prophets in the Seridó. The methodological framework of this work is the analysis of content proposed by Bardin (2010). In this study area, the experiences exert influence and relevance to the country people in the Seridó, because they consider them as a way to ease their anguishes face the possible drought in the region. The major role of the Prophet is to feed the hope of country people for better days, rather than contribute for the organization of the productive activities. Among the interviewed people, the forecast from the observation of winter experiences have greater credibility than the meteorological and disseminated by media. The Prophets of Rain base their prophecies on the set of natural elements present in the environment. Many factors stimulate the winter experiences by the Prophets nowadays, as cultural transmission, age, relationship with nature, level of education, faith, among others, but specially the productive activities (agriculture and cattle raising) and the droughts. The winter means abundance and happiness in this region and the experience is one of the ways that people find to minimize the anxiety and, according to their possibilities, to prepare for a year of droughts or for winter

Transtornos mentais comuns e uso de psicofármacos: impacto das condições socioeconômicas

OBJETIVO: Avaliar a influência das condições socioeconômicas na associação entre transtornos mentais comuns, uso de serviços de saúde e de psicofármacos. MÉTODOS: Estudo transversal populacional conduzido na cidade de Botucatu, SP, com amostragem probabilística, estratificada e por conglomerados. Foram realizadas entrevistas domiciliares com 1.023 sujeitos de 15 anos ou mais de idade, entre 2001 e 2002. Transtorno mental comum foi avaliado utilizando o Self Reporting Questionnaire (SRQ-20). O uso de serviços foi investigado com relação à quinzena anterior à entrevista e uso de psicotrópicos, nos três dias anteriores. Utilizou-se regressão logística para análise multivariável, considerando o efeito do desenho. RESULTADOS: No total da amostra, 13,4% (IC 95%: 10,7;16,0) procuraram serviços de saúde na quinzena anterior à entrevista. A procura de serviços de saúde se associou ao sexo feminino (OR=2,0) e à presença de transtorno mental comum (OR=2,2). Na amostra 13,3% (IC 95%: 9,2;17,5) referiram ter usado ao menos um psicotrópico, destacando-se os antidepressivos (5,0%) e os benzodiazepínicos (3,1%). Na análise multivariável, sexo feminino e presença de transtorno mental comum mantiveram-se associados ao uso de benzodiazepínicos. Renda per capita mostrou-se direta e independentemente associada ao uso de psicofármacos, conforme aumento da renda. CONCLUSÕES: Menor renda associou-se à presença de transtorno mental comum, mas não ao uso de psicotrópicos. A associação entre transtorno mental comum e uso de psicotrópicos e maior renda reforça a hipótese da existência de iniqüidades no acesso à assistência médica na população estudada.

Antibody response to newcastle disease vaccination in a flock of young partridges (Rhynchotus rufescens)

Ten young partridges (Rhynchotus rufescens) were vaccinated with the lentogenic strain of Newcastle disease virus. Another eight unvaccinated birds were kept in close contact with the treated flock. Antibodies levels were measured over the course of 3 mo in all birds using the hemagglutination inhibition (HI) test and the liquid-phase blocking enzyme-linked immunosorbent assay (LPB-ELISA). The LPB-ELISA was standardized, and the results were compared with those obtained with the HI test. Antibodies increased after 23 days postvaccination in 16 birds with no side effects as determined by both the HI test and the LPB-ELISA.

Perfil espacial e temporal de poluentes nas águas da represa municipal de São José do Rio Preto, São Paulo, Brasil

In this manuscript, seasonal and spatial trends of water collected from two sampling places in the Preto River in the Turvo-Grande watershed were evaluated. Water samples were collected during June/07 to July/08 and parameters sulphate, total organic carbon, ammonia, conductivity, dissolved oxygen, temperature, dissolved total solids and nitrate were quantified. Seasonal trend indicated sanitary effluents as a point source of contamination in both sampling points. Vertical trends demonstrated that the Municipal Dam was not stratified and received a diffuse source of pollutants from flooding and agriculture runoffs. It was also verified that there is relatively fast ammonia consumption kinetics having a half-life time of 1.43 h which can explain the low ammonia concentrations found in these aquatic bodies.

Algumas reflexões sobre relacionamentos afetivos e relações sexuais na adolescência

Sexo e sexualidade são temas bastante abordados pela sociedade e suas instituições, desde a mídia até a universidade. Também a escola de ensino fundamental e médio vem sendo apontada como espaço propício para se trabalhar com orientação sexual, considerando inclusive as questões em voga como a gravidez não planejada na adolescência, as relações de gênero, o combate à homofobia e as doenças sexualmente transmissíveis, particularmente a AIDS. O presente trabalho é resultado de uma pesquisa realizada com adolescentes de 14 a 19 anos, estudantes de uma escola pública de ensino médio, tendo como objetivos verificar como pensam e se comportam os jovens frente a questões e atitudes que envolvem sexo e sexualidade. A técnica de coleta de dados foi a redação, em que os sujeitos escreveram sobre idéias, práticas e comportamentos sexuais, sendo que no recorte feito para a apresentação deste artigo, nos prendemos aos relacionamentos afetivos e relações sexuais.

Utilização de medicamentos e fatores associados: um estudo de base populacional no Município de Campinas, São Paulo, Brasil

Este artigo analisa a prevalência da utilização de medicamentos segundo variáveis demográficas, socioeconômicas e de comportamentos relacionados à saúde, identificando fatores associados ao uso por meio de estudo transversal de base populacional, com 941 pessoas de 18 anos ou mais residentes em Campinas, São Paulo, Brasil. A amostragem foi realizada em múltiplos estágios, estratificada e por conglomerados. Utilizou-se o teste qui-quadrado, foram estimadas as razões de prevalência ajustadas por sexo e idade e os respectivos IC95%. Desenvolveu-se modelo de regressão múltipla de Poisson ficando associados ao uso: sexo feminino, idade de 40 anos e mais, morbidade referida nos últimos 15 dias e número de doenças crônicas. Os medicamentos mais consumidos foram para os sistemas cardiovascular e nervoso, e os fitoterápicos. A prevalência de uso de medicamentos em Campinas encontrou-se inferior à maioria dos estudos. Por meio de inquéritos de saúde locais espera-se conhecer o perfil de uso dos medicamentos pela população e garantir intervenções mais direcionadas para a Política de Assistência Farmacêutica.

Sulfation of intrinsic glycoproteins of the rabbit vitreous

The experiments reported here were designed to characterize the intrinsic vitreous glycoproteins and to understand the process of their sulfation. Rabbits were injected intravitreally with S-35-sodium sulfate and killed at several time intervals after injection. In another series of experiments, rabbits were injected either with S-35-sodium sulfate, H-3-fucose or H-3-tyrosine, associated or not associated with tunicamycin administration. Vitreous from the control eyes was also digested with N-glycosidase.. Furthermore, ciliary bodies, the putative source of the intrinsic vitreous glycoproteins, were incubated with S-35-sodium sulfate in the presence or absence of the protein synthesis inhibitor cycloheximide, and the culture media recovered for analysis. These and the vitreous samples of the other experiments were processed for sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and fluorography. Except for serum albumin, practically all polypeptide bands of the vitreous and culture media were labeled with radioactive sulfate and were shown to undergo renewal. The experiments using tunicamycin or enzyme treatment suggest that radioactive sulfate was incorporated not only into the carbohydrate side chains of the glycoproteins but also into the amino acid tyrosine of the polypeptide backbone of these glycoproteins.
