Admiralty Bay Benthos Diversity-A census of a complex polar ecosystem

A thorough census of Admiralty Bay benthic biodiversity was completed through the synthesis of data, acquired from more than 30 years of observations. Most of the available records arise from successive Polish and Brazilian Antarctic expeditions organized since 1977 and 1982, respectively, but also include new data from joint collecting efforts during the International Polar Year (2007-2009). Geological and hydrological characteristics of Admiralty Bay and a comprehensive species checklist with detailed data on the distribution and nature of the benthic communities are provided. Approximately 1300 species of benthic organisms (excluding bacteria, fungi and parasites) were recorded from the bay`s entire depth range (0-500 m). Generalized classifications and the descriptions of soft-bottom and hard-bottom invertebrate communities are presented. A time-series analysis showed seasonal and interannual changes in the shallow benthic communities, likely to be related to ice formation and ice melt within the bay. As one of the best studied regions in the maritime Antarctic Admiralty Bay represents a legacy site, where continued, systematically integrated data sampling can evaluate the effects of climate change on marine life. Both high species richness and high assemblage diversity of the Admiralty Bay shelf benthic community have been documented against the background of habitat heterogeneity. (C) 2010 Elsevier Ltd.

THE ACHIEVEMENT OF EXCELLENCE IN BRAZILIAN PROGRAMS OF POST-GRADUATION STRICTO SENSU WITH A DOCTORATE IN NURSING

This study aimed to identify how the graduate programs in nursing stricto sensu evaluated by the Nursing field at Coordination of Improvement of Higher Education Personnel, in the triennium 2007-2009, achieved excellence - grade 6. Descriptive exploratory study of nature documentary, which examined the data of Reports Indicators of these Programs at the site of the Coordination cited, in 2010. We analyzed 99 chips of 33 programs for the triennium 2007 to 2009, grouped in sub-clauses of Social and item categories for grades 6/7. Presents the indicators of excellence of Americans and Brazilians Programs, the results of the triennial assessment relating to sub-items of item 5 and the description of program performance specified for the grade 6. It follows that the excellence of Programs has been gradually achieved, with performance in certain categories as those required by international standards, overcoming the obstacles to the achievement of excellence in all its fullness.

Cursos de mestrado acadêmico na área de enfermagem: análise da carga horária

OBJETIVO: identificar, entre os cursos de Mestrado Acadêmico dos programas de pós-graduação em enfermagem brasileiros, analisados por ocasião da avaliação trienal (2007-2009) da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, a carga horária informada pelos programas para a formação de mestre. MÉTODO: trata-se de estudo descritivo, quantitativo, documental, com dados coletados em julho de 2010, mediante consulta aos relatórios da citada Coordenação, no quesito "Propostas dos Programas", dos Cadernos de Indicadores, disponíveis na web. RESULTADOS: foram encontradas discrepâncias entre as cargas horárias dos 32 cursos de Mestrado Acadêmico das diversas regiões do Brasil, sendo que a menor carga horária foi de 315 horas e a maior de 1.530 horas. CONCLUSÕES: há necessidade de maior discussão acerca da carga horária necessária à formação das competências e habilidades para o perfil desejado do egresso. O estudo propicia avanços no conhecimento da enfermagem, pois não foram identificadas investigações pregressas que tratem de tal tema. Espera-se que os cursos de Mestrado Acadêmico de enfermagem percebam-se nesse processo e revejam suas decisões pedagógicas, à luz dos novos modelos de formação/capacitação dos profissionais de enfermagem, centrados na ciência, tecnologia e inovação na área.

O alcance da excelência por programas brasileiros de pós-graduação stricto sensu com doutorado em enfermagem

Objetivou-se identificar como os programas de pós-graduação em enfermagem stricto sensu, avaliados pela Área de Enfermagem da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, no triênio 2007-2009, alcançaram a excelência - conceito 6. Estudo descritivo-exploratório, de cunho documental, que investigou os dados dos Cadernos de Indicadores destes programas, disponibilizados no site da mencionada Coordenação, em 2010. Foram analisadas 99 fichas, de 33 programas, referentes ao triênio 2007 a 2009, agrupadas nos sub-itens do quesito Inserção Social e categorias para notas 6/7. Apresentam-se os indicadores de excelência de programas norte-americanos e brasileiros, os resultados da avaliação trienal referentes aos sub-itens do quesito 5 e a descrição do desempenho dos programas indicados para o conceito 6. Conclui-se que a excelência dos programas vem sendo gradativamente conquistada, com desempenho em determinadas categorias, semelhantes às exigidas pelos padrões internacionais, vencendo-se os obstáculos para o alcance desta excelência, em sua plenitude.

On global linearization of planar involutions

Let phi: a"e(2) -> a"e(2) be an orientation-preserving C (1) involution such that phi(0) = 0. Let Spc(phi) = {Eigenvalues of D phi(p) | p a a"e(2)}. We prove that if Spc(phi) aS, a"e or Spc(phi) a (c) [1, 1 + epsilon) = a... for some epsilon > 0, then phi is globally C (1) conjugate to the linear involution D phi(0) via the conjugacy h = (I + D phi(0)phi)/2,where I: a"e(2) -> a"e(2) is the identity map. Similarly, we prove that if phi is an orientation-reversing C (1) involution such that phi(0) = 0 and Trace (D phi(0)D phi(p) > - 1 for all p a a"e(2), then phi is globally C (1) conjugate to the linear involution D phi(0) via the conjugacy h. Finally, we show that h may fail to be a global linearization of phi if the above conditions are not fulfilled.

Spatial-temporal variations in phytoplankton size and colored detrital matter absorption at global and regional scales, as derived from twelve years of SeaWiFS data (1998-2009)

A procedure has been proposed by Ciotti and Bricaud (2006) to retrieve spectral absorption coefficients of phytoplankton and colored detrital matter (CDM) from satellite radiance measurements. This was also the first procedure to estimate a size factor for phytoplankton, based on the shape of the retrieved algal absorption spectrum, and the spectral slope of CDM absorption. Applying this method to the global ocean color data set acquired by SeaWiFS over twelve years (1998-2009), allowed for a comparison of the spatial variations of chlorophyll concentration ([Chl]), algal size factor (S-f), CDM absorption coefficient (a(cdm)) at 443 nm, and spectral slope of CDM absorption (S-cdm). As expected, correlations between the derived parameters were characterized by a large scatter at the global scale. We compared temporal variability of the spatially averaged parameters over the twelve-year period for three oceanic areas of biogeochemical importance: the Eastern Equatorial Pacific, the North Atlantic and the Mediterranean Sea. In all areas, both S-f and a(cdm)(443) showed large seasonal and interannual variations, generally correlated to those of algal biomass. The CDM maxima appeared in some occasions to last longer than those of [Chl]. The spectral slope of CDM absorption showed very large seasonal cycles consistent with photobleaching, challenging the assumption of a constant slope commonly used in bio-optical models. In the Equatorial Pacific, the seasonal cycles of [Chl], S-f, a(cdm)(443) and S-cdm, as well as the relationships between these parameters, were strongly affected by the 1997-98 El Ni o/La Ni a event.
