Prática e duração do aleitamento materno de crianças matriculadas em escolas particulares do município de São Paulo, SP

presente estudo descreve a prática de aleitamento materno e verifica possíveis fatores de associação com a duração do aleitamento materno exclusivo e aleitamento materno em crianças de escolas particulares do município de São Paulo. Fizeram parte do estudo 566 crianças, com 2 a 6 anos completos de idade. Foi considerada como variável dependente a duração do aleitamento materno (aleitamento materno exclusivo e aleitamento materno), e como independente idade e escolaridade materna, condição de trabalho da mãe e sexo da criança. A caracterização da amostra é apresentada por meio de distribuições de freqüências. A variável aleitamento materno foi descrita em categorias, e para análise foi utilizada como variável contínua. Para a análise da relação entre duração do aleitamento materno e as variáveis independentes utilizou-se a técnica de regressão múltipla de Cox adotando-se critério p < 0,05 para decisão de significância. Não houve associação entre as variáveis estudadas e tempo de duração das duas formas de aleitamento. Cerca de 80% das crianças deixaram de ser amamentadas exclusivamente antes dos seis meses de vida, o que mostra a necessidade de continuar o desenvolvimento de ações para incentivo e apoio à amamentação

Genetic-morphometric variation in Culex quinquefasciatus from Brazil and La Plata, Argentina

Variation among natural populations of Culex (Culex) quinquefasciatus Say is associated with different vectorial capacities. The species Cx. quinquefasciatus is present in the equatorial, tropical and subtropical zones in the Brazilian territory, with intermediate forms between Cx. quinquefasciatus and Culex pipiens occurring in regions of latitudes around 33°-35°S. Herein, we studied geographically distinct populations of Cx. quinquefasciatus by genetic characterization and analysis of intra-specific wing morphometrics. After morphological analysis, molecular characterization of Cx. quinquefasciatus and intermediate forms was performed by polymerase chain reaction of the polymorphic nuclear region of the second intron of the acetylcholinesterase locus. Additionally, the morphology of adult female wings collected from six locations was analyzed. Wing centroid sizes were significantly different between some geographical pairs. Mean values of R2/R2+3 differed significantly after pairwise comparisons. The overall wing shape represented by morphometric characters could be divided into two main groupings. Our data suggest that Brazilian samples are morphologically and genetically distinct from the Argentinean samples and also indicated a morphological distinction between northern and southern populations of Brazilian Cx. quinquefasciatus. We suggest that wing morphology may be used for preliminary assessment of population structure of Cx. quinquefasciatusin Brazil

Síndrome de burnout em professores do ensino médio de escolas pertencentes à gerência regional de educação e inovação (GEREI) do município de tubarão (SC)

Este artigo baseia-se em dissertação de mesmo título, apresentada à Universidade do Sul de Santa Catarina. Tem por objetivo estimar a prevalência da síndrome de burnout em professores do Ensino Médio da rede pública estadual em Tubarão (SC). Um grupo de 101 professores de sete Escolas de Ensino Médio, com atividades em sala de aula, responderam a um questionário de dados sociodemográficos e funcionais e ao Maslach burnout inventory - educators survey. Verificou-se a existência de correlação entre os escores fatoriais das três dimensões da síndrome de burnout e as variáveis independentes. A prevalência da síndrome de burnout foi de 12,9%. Encontrou-se correlação positiva entre tempo de serviço e a dimensão Despersonalização (r=0,2101; p=0,035), bem como entre a dimensão Despersonalização e a situação funcional (r =0,2929; p=0,003). Os resultados indicam alta chance de desenvolvimento de burnout ou burnout em curso. A adoção de medidas de promoção à saúde mental dos professores poderia evitar a despersonalização entre professores observada nesse estudo

Confederações indígenas em luta por participação política, comercial e territorial: Argentina, 1852 - 1859

Entre 1852 e 1859, a atual Argentina se encontrava politicamente dividida entre Buenos Aires e a Confederação, que congregava as demais Províncias. Nesse período, diferentes grupos étnicos dos pampas, dos Andes e da Patagônia se organizaram em confederações indígenas com o objetivo de enfrentar os avanços territoriais, defender suas autonomias e a participação em lucrativas redes de comércio. Nesta luta por autonomia política, territorial e comercial, negociaram com os grupos criollos em luta pelo poder, avaliaram seus projetos e aderiram a aquele que os reconheceu enquanto interlocutores políticos e aliados militares. Participantes ativos da política argentina, conseguiram reconquistar territórios e oferecer intensas resistências aos criollos.

Transfer and Reverse Transfer of Knowledge of International Acquisitions: the case of the acquisition of the Perez Companc by Petrobras in Argentina

The objective of this article was to analyze the processes of transfer and reverse trans fer of knowledge following. international acquisitions made by Brazilian multinational companies. Reverse transfer is understood,as the process of transferring knowledge from the acquired company to the acquirer. Therefore, a case study was conducted on the acquisition of the Perez Companc group by Petrobras in Argentina. The study is qualitative. Primary data were obtained and eight members of the international managing board of Petrobras were interviewed. After the first moment of integration, reported as conflictive, there was a better integration of the companies, mainly in the technical areas of, the oil and gas exploration activities. The size of Perez Companc, its aim (a company of energy, not only oil and gas company) and the length of time were critical factors for the transfer of best practices between the companies. The expatriation of the employees is seen as a key-tool, as well as the technical visits, for the transfer of knowledge.. An. additional contribution of the study was to present the results of the research on the process of transfer and reverse transfer of knowledge in Brazilian multinational companies, since most studies on the theme focus on the motivators and challenges concerning these processes.

The Internationalization Process as Generator Element of Dynamic Capacities: the case of WEG in Argentina and China

The objective of he article is to research the dynamic capacities developed and used by WEG in its internationalization process and to explain how these capacities help the company defends and supports competitive advantage. The article presents an exploratory study of the internationalization process of WEG in Argentina and China. This article has as analysis approach the dynamic capacities, contributes to the literature of international management in two aspects. First, it adds the analytical look of the internationalization based on dynamic capacities that are still well restricted. Second, when working the dynamic capacities as central element of the analysis of the internationalization process, it Proposes one framework of integrative analysis of the economic and behavioral theories that are used to explain the process of companies`-internationalization, although they are dealt independently and sometimes antagonistic way. The result shows as the dynamic capacities are articulated in the base of WEG in its process of internationalization for Argentina and the subsequent movement for China. The developed dynamic capacities in Argentina were acquired for the Brazilian headquarter and could have been applied in the process of internationalization for China. However, a more complex organizational structure cannot be identified where the inter-subsidiary relationships could share dynamic capacities as proposed in framework.

Anatomy and phylogenetic relationships of a new catfish species from northeastern Argentina with comments on the phylogenetic relationships of the genus Rhamdella Eigenmann and Eigenmann 1888 (Siluriformes, Heptapteridae)

Rhamdella cainguae, a new species of the family Heptapteridae is described from the Arroyo Cuna-Piru, a tributary of the Rio Parana, in the subtropical forest of Misiones, northeastern Argentina. The presence of a large differentiated ovoid area on the supraorbital laterosensory canal along the frontal-sphenotic boundary, delimited by the slender dorsal walls of the bones, and with no foramen for a laterosensory branch, is an autapomorphy for R. cainguae. A detailed description of the skeleton and laterosensory system of R. cainguae is provided. The genus Rhamdella is rediagnosed on the basis of three autapomorphies: a very large opening in the frontal for the exit of the s6 ( epiphyseal) branch of the supraorbital laterosensory canal ( reversed in R. rusbyi), a large optic foramen, and a dark stripe along the lateral surface of the body ( reversed in R. rusbyi). Rhamdella is considered to be the sister group of a large heptapterid clade composed of the Nemuroglanis sub-clade plus the genera Brachyglanis, Gladioglanis, Leptorhamdia, and Myoglanis. Rhamdella is herein restricted to five valid species: R. aymarae, R. cainguae, R. eriarcha, R. longiuscula, and R. rusbyi. A sister group relationship between R. aymarae and R. rusbyi is supported by three synapomorphies. Rhamdella cainguae shares 12 apomorphic features with R. eriarcha and R. longiuscula.

Both human immunodeficiency virus-infected and human immunodeficiency virus-exposed, uninfected children living in Brazil, Argentina, and Mexico have similar rates of low concentrations of retinol, beta-carotene, and vitamin E

Our objective was to describe the prevalence of low concentrations of retinol, beta-carotene, and vitamin E in a group of human immunodeficiency virus (HIV)-infected Latin American children and a comparison group of HIV-exposed, uninfected children. Our hypothesis was that the rates of low concentrations of these micronutrients would be higher in the HIV-infected group than those in the HIV-exposed, uninfected group. This was a cross-sectional substudy of a larger cohort study at clinical pediatric HIV centers in Latin America. Serum levels of micronutrients were measured in the first stored sample obtained after each child`s first birthday by high-performance liquid chromatography. Low concentrations of retinol, beta-carotene, and vitamin E were defined as serum levels below 0.70, 0.35, and 18.0 mu mol/L, respectively. The Population for this analysis was 336 children (124 HIV-infected, 212 HIV-exposed, uninfected) aged I year or older to younger than 4 years. Rates of low concentrations were 74% for retinol, 27% for beta-carotene, and 89% for vitamin E. These rates were not affected by HIV status. Among the HIV-infected children, those treated with anti retrovirals were less likely to have retinol deficiency, but no other HIV-related factors correlated with micronutrient low serum levels. Low concentrations of retinol, beta-carotene, and vitamin E are very common in children exposed to HIV living in Brazil, Argentina, and Mexico, regardless of HIV-infection status.
