This article presents the results of a 1991 household income survey of the three main groups in Cuban agriculture: wage workers on state farms, members of production co-operatives, and peasant producers. It is shown that since the 1959 revolution household income levels in the agricultural sector have improved dramatically, while regional differences have been ameliorated considerably. Households in the private sector of Cuban agriculture have fared the best. It is also demonstrated that agricultural households rely on multiple sources of income to generate their livelihood. Rather than being strictly proletarian, collective, or petty commodity producers, these households are best characterized by the multiple class relations in which they participate.  相似文献

This article examines the parallel phenomena of narrowing wage differentials among major groups of workers and widening wage inequality in general in Mexico during the 1980s and 1990s. In trying to understand this paradox, it finds that a human-capital model cannot explain wage determination in the 1990s. Although employees with higher skills and education have enjoyed increasingly higher relative returns to their human capital, much of the variance in wages is not attributable to differences in human capital or rates of return. Discriminatory wage policies have combined with policies of trade liberalization to markedly widen the wage gap between lower-paid and higher-paid workers.  相似文献

An entry in Edith Safstrom’s diary, We Wia Ragai, marks her first posting to the girl’s mission school in the Solomon Islands, and is a Mota phrase told to her by lay missionary colleague, Ida Wench. The phrase essentially means “it is good to be here among you all” and echoed Edith’s thoughts on life at the school on tiny Mbungana Island. The Safstrom collection of artifacts held in the Museum of Victoria and Edith’s diaries unwrap a synergetic dialogue between lay missionary women and Indigenous women and children. The collection circumscribes a lay missionary’s collective experience of Christianity and acceptance of Indigenous cultural heritage from 1921 to 1942 in the Solomon Islands.  相似文献

The prevalence of digital image analysis in studies spanning a wide range of fields makes the importance of set-up design decidedly important for repeatability and testing between studies, especially for those interested in the analysis of microscopic properties. This note outlines some important guidelines for setting up an image analysis protocol, and provides a case study based on the digital analysis of dental cement. Our method allowed for us (1) to get data through the conversion of optical luminance into numerical values and (2) to accurately measure image features through numerical analysis.  相似文献
