Avaliação nutricional de dietas de trabalhadores em relação a proteínas, lipídeos, carboidratos, fibras alimentares e vitaminas

Estudos sobre composição de alimentos largamente consumidos pela população são fundamentais para estabelecer se uma determinada dieta é adequada em relação aos nutrientes essenciais. No presente trabalho, são apresentados resultados de análises de nutrientes realizadas em dietas representativas do consumo alimentar de trabalhadores de indústria de autopeças da cidade de São Paulo (homens de 19 a 56 anos), coletadas a partir da porção em duplicata de todos os alimentos e bebidas consumidos durante 3 dias consecutivos. Foram determinados os teores de proteínas, lipídeos, carboidratos, cinza, umidade, fibras alimentares e vitaminas B1, B2 e piridoxina em 24 dietas. Comparando-se os resultados obtidos com as novas recomendações (DRIs), verificou-se que as dietas dos trabalhadores atingiram adequação de 100% em carboidratos e 96% em proteínas e lipídeos. Em relação às fibras dietéticas, as dietas foram inadequadas, com apenas 4,2% de adequação. Todas as dietas foram adequadas em vitaminas B1 e B2, enquanto que 58% das dietas foram inadequadas em relação à piridoxina.

Os limites da participação dos trabalhadores nos ganhos das empresas

This article argues that workers’ share in profits are actually a share in extra surplus value obtained by means of more intensified labor. Cost reductions obtained by means of more intensified lean production methods cause wages to represent a smaller fraction of the product of a working day when measured at market value. The increased market rate of surplus value is the basis for workers’ shares in profits. However, as competition continuously levels out such advantages, the share in profits becomes dependent on a continuous strive to reducing costs and intensifying labor.

Fluxo de empregos, fluxo de trabalhadores e fluxo de postos de trabalho no Brasil

Job flows, workers flows and employment flows in Brazil. The labor market is in constant flux. When measuring labor market mobility, it is usual to estimate labor market flow statistics, such as worker reallocation and job reallocation. The goal of this paper is to present previously unknown within plant job reallocation statistics for Brazil. The within plant job reallocation is measured as changes in the occupational mix of the plant. The within plant job reallocation allows a decomposition of worker turnover decomposition into matching, technological change and labor demand factors. Using formal labor market data for Brazil, from 1996 to 2001, our results suggest that technological change accounted for a limited share of worker turnover. More than a quarter of worker turnover can be attributed to labor demand shifts and more than 50% of worker turnover is due to matching.
