Abstract: the aim of this paper was to understand how the media in the state of pernambuco portrays dengue fever, a disease that is affecting more and more brazilians. taking the explosive epidemic of 2002 as the starting point, we tried to understand the effects of meaning produced by the press in a comparative discourse strategy analysis used in 2002, 2004, 2006 and 2008. we selected 291 articles and notes published in the jornal do commercio (recife-brazil), on the situation of this viral disease in the state of pernambuco in the four years. we also analysed dengue fever surveillance reports published by the health department of pernambuco. to complement discourse analysis, we proposed the construction of a medialogy diagram, a graphic representation that tries to establish a relationship between newspaper texts and number cases of dengue reported. results indicate that media coverage generally followed the development of dengue fever cases, with more news published during the epidemic periods and showing the appeal of the illness as a mass media phenomenon despite its risk to the brazilian people.

Abstract: in 2009, the emergence of cases of influenza a(h1n1) - the popular flu - in 207 countries indicated the registration of the first pandemic of the xxi century, as predicted in reports from health authorities some years ago. in brazil, 27,850 cases of swine were confirmed, of which 1,632 died, representing 18,6% of deaths worldwide and 27,7% in the americas, according to the health ministry of brazil (2009). the media have linked the emergence of flu as a differentiated 'new edition' of flu, due to the identification of a new subtype of influenza virus that could be as lethal as the old one. a similar fear to what had been experienced also with avian influenza in 1997, prompting officials to remain on alert. this article aims to evaluate the production of news on influenza a(h1n1) in the three main national magazines in brazil. we chose to analyze the eigth covers of magazines veja, istoé and época published during the first months of the pandemic, in the beginning of 2009. based on concepts of discourse analysis and journalism theory, the analysis indicates that the news can be divided into two phases, focusing initially on the alarm over the fear of new virus and deaths recorded and afterwards on the control due to the finding that the disease presented less risk than previously thought and to the actions taken to fight it.

Abstract: The objective of the present study is to assess the strategic behavior of female entrepreneurs. The study was based on Miles and Snow’s (1978) taxonomy of strategic types to identify these strategic forms. The methodology was a quantitative research, with a questionnaire structured in 75 small businesses owned and managed by women. Choosing women as the object of this study is mainly due to the fact that the insertion of women in the productive system constitutes a privileged factor for analyzing the transformations happening in the feminine world during these modern days. From comparisons of statistical variables reflecting competitive strategy, we conclude that the four strategic types proposed by Miles and Snow exist: prospector, analyzer, defender and reactor. Among which, the most common strategic profile was the analyzer. O objetivo desse trabalho é conhecer o comportamento estratégico de mulheres empresárias. Para tanto, baseou-se na taxonomia de tipos estratégicos de Miles e Snow (1978) para identificar essas formas estratégicas. A metodologia de estudo foi procedimento quantitativo, com aplica o de questionário estruturado em setenta e cinco pequenas empresas de propriedade e gest o feminina. A escolha de uma amostra feminina deve-se, essencialmente, ao fato de que a inser o da mulher no sistema produtivo constitui um fator privilegiado de análise das transforma es que vêm ocorrendo com o feminino na modernidade. A partir de compara es estatísticas entre variáveis que traduzem a estratégia competitiva, conclui-se que há ocorrência dos quatro tipos estratégicos propostos por Miles e Snow, isto é, as estratégias, defensiva, analítica, prospectora e reativa. A estratégia mais frequente foi a analítica.

Abstract: To copy natural photosynthesis process we need to understand and explain the physics underneath its first step mechanism, which is “how to separate electrical charges under attraction”. But this Nature’s nanotechnological creation is not yet available to the scientific community. We present a new interpretation for the artificial and natural photosynthetic mechanism, concerning the electrical charges separation and the spent energy to promote the process. Interface (e–, h+) recombination and emission is applied to explain the photosynthetic mechanisms. This interpretation is based on energy bands relative position, the staggered one, which under illumination promotes (e–, h+) charges separation through the action of an interface electric field and energy consumption at the interface of both A/B generic materials. Energy band bending is responsible by the interface electric field (and the driving force) for the charges separation. This electric field can be as high or above that for p-n semiconductor junctions (104 - 105 V/cm). This physical effect is not considered by most of the researches. Without an electric field and without spending energy to separate electrical charges, any other existing model violates physical laws. The staggered energy band type is the only energetic configuration that permits charges separation under illumination and energy loss to perform the process. Application to natural photosynthesis and artificial photovoltaic material and their energetic configurations are discussed. Examples for A/B being III-V/III-V, TiO2/materials and II-VI/II-VI staggered energy band gap pairs are presented. In the proposed quantum mechanism, plants are able to eliminate most of the 79% of the absorbed visible light, according to the published reflection and transmission data. Moreover, the proposed mechanism can be applied to explain green fluorescent protein - GFP, charge transfer states - CTS and Fluorescent Resonance Energy Transfer - FRET. As recent literature experimental results propose photosynthesis as a quantum controlled mechanism, our proposition goes forward this direction.

Abstract: O campo científico da agropecuária é objeto do estudo que tem como objetivo investigar a constru o da posi o dominante ocupada pela Embrapa entre as entidades que se voltam para esse domínio do saber e trazer algumas inferências. Na consecu o desses propósitos, optou-se por empregar métodos bibliométricos e sociométricos para uma leitura inscrita no paradigma positivista, considerando-o mais próximo aos cientistas que comp em o campo em evidência, convidando-os à reflex o e facilitando-a ao utilizar métodos de mesma natureza de suas pesquisas. As evidências coletadas parecem indicar que a proje o da Embrapa n o restou explicada por mérito científico, o que implicou a necessidade de esquadrinhar explica es alternativas, quando se buscou em Bourdieu ferramental para a tarefa. Conclui-se que a Embrapa é central no campo estudado ao cuidar em projetar uma imagem, t o real quanto de fato, à medida que n o é contestada além de reclamos n o sistematizados e que dispensam dados objetivos - situa o que por si mesma provoca outro questionamento, também encaminhado na pesquisa. The agricultural scientific field is the object of this study, which aims to investigate the construction of the dominant position occupied by Embrapa between those who turn to this field of knowledge and to formulate some inferences. In achieving these purposes, we chose to use bibliometric and sociometric methods for a reading in a positivist paradigm approach, considering it as more friendly to the scientists in the agricultural field, asking them to reflect, facilitating it by using methods of the same nature as their research. The evidence collected suggests that the projection of Embrapa is not explained by scientific merit, which meant the need to probe alternative explanations, when we employed the concepts of Bourdieu for the task. We conclude that Embrapa is central in the scrutinized field in caring for the projection of an image, as real as it is, as long as it is not contested beyond non-systematized claims and those which dispense with objective data - which in itself cause further questioning, also referred to in this research.

Abstract: Diante de um contexto que exige posturas proativas dos gestores, esta pesquisa intentou conhecer as estratégias adotadas por mulheres empreendedoras na cidade de Vitória da Conquista, regi o sudoeste da Bahia. Ao longo do estudo buscou-se conhecer o seu comportamento estratégico, pois se entende que a sobrevivência dos empreendimentos, principalmente dos pequenos negócios, está relacionada à vis o estratégica de seus empreendedores. A escolha de uma amostra feminina deve-se, essencialmente, ao fato de que a inser o da mulher no sistema produtivo constitui um fator privilegiado de análise das transforma es que vêm ocorrendo com o feminino na modernidade. Além disso, o tema empreendedorismo feminino emerge como um assunto muito pouco estudado e carente de pesquisas n o só teóricas como também empíricas. A análise dos dados coletados permitiu verificar que o comportamento estratégico predominante entre as empreendedoras, de acordo com a tipologia de Miles e Snow (1978), é o prospector.

In a context that demands proactive attitudes of managers, this survey sought to describe strategies adopted by women entrepreneurs in Vitória da Conquista, a city in Southwest Bahia, Brazil. Their strategic behavior was investigated with an understanding that survival, especially for the small businesses, is related to the strategic vision of the entrepreneurs. Women were chosen, essentially, because of their growing participation in the productive system which is a modern trend where their entrepreneurship has attracted little study and research, the
