Em um ambiente global dinmico e competitivo, muitas empresas notam que constante desenvolvimento e lanamento de novos produtos so atividades-chave para seu crescimento e sobrevivncia. Hoje, um dos maiores desafios enfrentados por tais empresas envolve saber como agir em um mundo em que tanto o escopo como a estrutura do ambiente competitivo esto em constante mudana, e em que reestruturaes e mudanas de portflio so centrais para as companhias que visam capitalizar com o crescimento global. Tanto o rpido ritmo de inovao tecnolgica quando a crescente afluncia de economias emergentes apresentam riscos e oportunidades para as empresas, o que torna importante no apenas que estas estejam atentas ao lanamento de produtos de ltima gerao para mercados desenvolvidos: faz-se tambm necessrio que saibam como lanar produtos antigos para novos mercados. Usando o mercado brasileiro como um exemplo, esta dissertao procurou estudar como multinacionais tm utilizado anncios publicitrios no lanamento, para novos mercados, de categorias e subcategorias de produtos j vendidas em outros pases. Aps uma reviso da literatura disponvel, do desenvolvimento de proposies, e da avaliao destas atravs de trs estudos de caso, foi possvel verificar a existncia de alguma linearidade entre os casos e a literatura estudada, incluindo: uma busca pela legitimao da categoria que precede quela pela da marca; o uso de especialistas para a legitimao da categoria; o uso de apelos baseados em argumentos; e a divulgao de mais de uma caracterstica de produto por anncio. No entanto, dadas algumas discrepncias entre o que foi observado nos casos e aquilo descrito na literatura consultada, tambm foi possvel verificar que a maneira como os anncios so feitos em diferentes lugares depende igualmente do cenrio competitivo enfrentado pela empresa, bem como de variantes econmicas e culturais especficas da localidade em questo.

This article investigates which semantic categories, as defined in Functional Discourse Grammar, formally manifest themselves in a sample of native languages of Brazil, and the extent to which the distribution of these manifestations across categories can be described systematically in terms of implicational hierarchies. The areas subjected to investigation are basic interrogative words, basic demonstrative words, and nominalization strategies.

Background: We aimed to verify the association of risk behavior aggregation in different categories of physical activity (PA) with the presence of cardiovascular risk factors (RF) employees at a public university. Method. We analyzed data of 376 employees, which were visited in their workplace for measurement of weight, height and questionnaires to identify the risk behaviors and risk factors. Chi-square test was used to analyze the association between the dependent and independent variables and binary logistic regression was used to construct a multivariate model for the observed associations. Results: Associations were found between the aggregation of following risk behaviors: smoking, alcohol consumption and physical inactivity, considered in different categories of PA, and the increase in RF, except for the presence of hypertriglyceridemia. Individuals with two or more risk behaviors in occupational PA category are more likely to be hypertensive (3.04 times) and diabetes (3.44 times). For the free time PA category, these individuals were 3.18 times more likely to have hypercholesterolemia and for locomotion PA, more likely to be hypertensive (2.42 times) and obese (2.51 times). Conclusion: There are association between the aggregation of two or more risk behaviors and the presence of cardiovascular RF. 2013 Bernardo et al.; licensee BioMed Central Ltd.

INTRODUO: Estudos epidemiolgicos sobre a distribuio genotpica do HCV na Amaznia Brasileira so escassos. Baseado nisto, determinamos o padro de distribuio genotpica do HCV em diferentes categorias de exposio no Estado do Par, Amaznia Brasileira. MTODOS: Estudo transversal foi realizado com 312 indivduos infectados pelo HCV, pertencentes a diferentes categorias de exposio atendidas pelo HEMOPA, CENPREN e uma clnica privada de hemodilise em Belm. Eles foram testados quanto presena de anticorpos anti-HCV por teste imunoenzimtico, RNA-HCV utilizando PCR em tempo real e genotipados atravs de anlise filogentica da 5' UTR. Os grupos de populaes foram caracterizados epidemiologicamente de acordo com dados coletados em breve entrevista ou consulta de pronturios mdicos. RESULTADOS: Em todas as diferentes categorias de exposio ao HCV, foram encontrados predomnio do gentipo 1. A distribuio genotpica do HCV em doadores de sangue (BD) foi constituda pelos gentipos 1 (94%) e 3 (6%). Todos os pacientes com doenas hematolgicas crnicas (PCHD) possuam gentipo 1. A distribuio genotpica em usurios de drogas ilcitas (DU) foi constituda pelos gentipos 1 (59,6%) e 3 (40,4%). Em pacientes em hemodilise (PUH) foram detectados os gentipos 1 (90,1%), 2 (3,3%) e 3 (6,6%). Finalmente, a frequncia entre os gentipos 1 e 3 foi significativamente diferente entre os grupos: BD e DU, PUH e DU, PUH e PCHD, e PCHD e DU. CONCLUSES: A frequncia genotpica e distribuio de HCV em diferentes categorias de exposio no Estado do Par mostraram predominncia do gentipo 1, independentemente do possvel risco de infeco.

Um mtodo quantitativo para se estimar o consumo alimentar e o aporte energtico das diferentes categorias alimentares apresentado atravs da reconstruo das presas ingeridas com base em estruturas corporais no digerveis. Para tal, o presente estudo estabelece, atravs do exame dos contedos estomacais de 1.086 exemplares dissecados de Macrodon ancylodon (Bloch & Schneider, 1801), Stellifer rastrifer (Jordan, 1889) e Stellifer naso (Jordan, 1889), as equaes das relaes funcionais entre o peso das presas e estruturas corporais. Com as categorias reconstrudas foi possvel quantificar o alimento ingerido pelos espcimes. Os resultados indicaram que existe uma marcada diferena, tanto na composio das categorias alimentares, bem como no aporte energtico acompanhando o desenvolvimento ontognico do predador.

This is a study about the relationships between authors and the main thematic categories in the papers published in the last five International ISKO Conferences, held between 2002 and 2010. The aim is to map the domain as ISKO conferences are considered the most representative forum in the field. The published papers are considered to indicate the relationships between authors and themes. The Classification Scheme for Knowledge Organization Error! Bookmark not defined Literature (CSKOL) was used to categorize the papers. The theoretical and methodological foundations of the study can be found in the concept of domain analysis proposed by Hjorland. The analysis of the papers (n=146) led to the identification of the most productive authors, the networks representing the relationships between the authors as also the categories that constitute the primary areas of research.

PURPOSE: To evalulate the applicability of the Revised Diagnostic Criteria for Vogt-Koyanagi-Harada (VKH) disease to Brazilian patients and to verify the association between different disease categories, clinical parameters, and the presence of HLA-DRB1*0405. DESIGN: A retrospective observational case series. METHODS: Medical charts of 67 patients (10 to 64 years in age; 12 men and 55 women), from the Uveitis Service, Hospital das Clinicas, University of Sao Paulo School of Medicine (HCFMUSP), Sao Paulo, Brazil were reviewed. Patients, previously diagnosed with VKH disease using criteria proposed by the American Uveitis Society, underwent retrospective classification based on the Revised Diagnostic Criteria. The degree of concordance was assessed. At presentation, 46 patients (69%) were in the early phase. In this group, the mean time from disease onset to treatment was 15 days (range, one to 30 days). Forty-eight patients (72%) were typed for HLA-DRB1*0405 by polymerase chain reaction-sequence specific primer and polymerase chain reaction,sequence, specific oligonucleotides primer. Disease categories, phase at initial presentation, and ocular complications were analyzed. RESULTS: There was a 100% of concordance between the two criteria. Disease was classified as complete in 10 patients (15%), incomplete in 37 patients (55%), and probable in 20 patients (30%). In each group, respectively, 90%, 76%, and 45% were in the early phase at presentation (P = .017). There was no association between disease categories, the presence of HLA-DRB1*0405, and clinical parameters. CONCLUSION. The Revised Diagnostic Criteria proved useful for diagnosis of VKH disease in Brazilian patients. The present retrospective study did not find any association between disease category and severity parameters. To better understand the relevance of disease categories, a minimum follow-up period to categorize patients should be included in future prospective studies. (Am J Ophthalmol 2009;147:339-345.

Analysis of Brazilian fishers` classifications of 24 marine (Atlantic coast) and 24 freshwater (Amazon) fish species reveals that fishers from the Atlantic coast identify fish mainly through generic names (primary lexemes), while riverine Amazonian fishers typically identify them through binomials. The similarity of Amazonian fish species seems to contribute to the detailed folk taxonomy used by riverine fishers. High-ranking groups called ""relatives"" or ""cousins"" are sorted by fishers in terms of similarities of habitat, diet, and morphology and, secondarily, behavior. The general correspondence between the folk and scientific taxonomies reinforces the reality of both the supracategories used by these fishers and the biological groups as discontinuities in nature. Given the urgency of biological inventories and the lack of knowledge of high-biodiversity environments such as the Atlantic Forest and the Amazon, these results suggest that fisher knowledge and experience could contribute to scientific research.

The adoption of no-till system (NTS) combined with crop-livestock integration (CLI) has been a strategy promoted in Brazil, aiming to maximize areas yield and increase agribusiness profitability. This study aimed to evaluate grains yield and phytotechnical attributes from maize and soybean culture by CLI system under NTS after winter annual pure and diversified pastures with the absence or presence of grazing animals. The experiment was installed in Castro (Parana State, Brazil) on in a dystrophic Humic Rhodic Hapludox with a clay texture, using experimental design of randomized complete blocks in 4 x 2 factorial scheme with three replications. Treatments included four pasture combinations (diversified or pure) and animal categories (light and heavy) subjected or not to grazing animals during the winter. During 2008/09 and 2009/10 summers, the area was cultivated with soybeans and maize, respectively, with yield assessment of grains and phytotechnical attributes. Treatments did not alter the yield and weight of a thousand seeds (WTS) of soybeans. In maize culture, the grazing animal during the winter increased the plant population and grains yield, but gave slight decrease in WTS. Pasture combinations (diversified or pure) and animal categories (light and heavy) did not interfere in soybean culture, but benefited the maize crop.
