Este trabalho se insere na linha de estudos empíricos que visam avaliar os efeitos que a abertura econômica teve no mercado de trabalho brasileiro, a partir do referencial teórico fornecido pelo modelo de Hecksher-Ohlin- Stolper-Samuelson. Especificamente, objetiva identificar a relação entre o grau de abertura comercial e o diferencial de remuneração entre os trabalhadores classificados segundo o grau de qualificação e ocupados em setores selecionados da indústria de transformação das regiões metropolitanas de São Paulo (RMSP) e Campinas (RMC) em 1991 e 2000. Os resultados mostram que o primeiro impacto da abertura econômica (começo dos anos 90) foi de redução generalizada das remunerações com viés de redução dos diferenciais de remuneração. No final da década, a situação se inverteu e as dinâmicas regionais diferiram com um viés de aumento na desigualdade na RMSP e de redução na RMC.

Introduction: Vitamin B12 deficiency usually presents with pernicious anemia or various neuropsychiatric manifestations such as neuropathy, myelopathy, dementia, cerebellar ataxia, optic atrophy, pscyhosis and mood disorders. Hence vitamin B12 deficiency should be identified. The local population in our area mainly comprises of vegetarians, this study was initiated with a view to assess their B12 status early, to rule out its deficiency and help to prevent further complications. Methodology: We analyzed serum B12 levels in 396 cases by competitive chemiluminescent immunometric method using Immulite instrument. Result: It was found that B12 levels were significantly low in 260(65.6%) patients (P

Abstract Background Remote sensing technology provides detailed spectral and thermal images of the earth's surface from which surrogate ecological indicators of complex processes can be measured. Methods Remote sensing data were overlaid onto georeferenced entomological and human ecological data randomly sampled during April and May 2001 in the cities of Kisumu (population ≈ 320,000) and Malindi (population ≈ 81,000), Kenya. Grid cells of 270 meters × 270 meters were used to generate spatial sampling units for each city for the collection of entomological and human ecological field-based data. Multispectral Thermal Imager (MTI) satellite data in the visible spectrum at five meter resolution were acquired for Kisumu and Malindi during February and March 2001, respectively. The MTI data were fit and aggregated to the 270 meter × 270 meter grid cells used in field-based sampling using a geographic information system. The normalized difference vegetation index (NDVI) was calculated and scaled from MTI data for selected grid cells. Regression analysis was used to assess associations between NDVI values and entomological and human ecological variables at the grid cell level. Results Multivariate linear regression showed that as household density increased, mean grid cell NDVI decreased (global F-test = 9.81, df 3,72, P-value = 2 = 0.26). Given household density, the number of potential anopheline larval habitats per grid cell also increased with increasing values of mean grid cell NDVI (global F-test = 14.29, df 3,36, P-value = 2 = 0.51). Conclusions NDVI values obtained from MTI data were successfully overlaid onto georeferenced entomological and human ecological data spatially sampled at a scale of 270 meters × 270 meters. Results demonstrate that NDVI at such a scale was sufficient to describe variations in entomological and human ecological parameters across both cities.
