‘The rural proletariat’ has been employed as a sociological category to describe Caribbean populations for nearly 25 years, but confusion about such populations persists. Proletarianisation, the definition of rural proletariats, and the Marxist conception of consciousness, as applicable to such groups, are discussed in the following paper. The Cuban case is described to exemplify the European bias of some analysts, and the difficulties created by an uncritical transfer of western conceptions of class and of class consciousness to a colonial agrarian situation. A special effort is made to conceptualise the rural proletariat in terms of its relationships to the peasantry, and of the ‘concealment’ of landless workers in peasant communities. 相似文献

A longitudinal study of 25 families, with children aged 14 months—5 years, in joint custody, is reported. Varying motivations that lead divorcing parents to undertake and sustain joint custody are discussed, together with the stresses and gratifications of these arrangements for the parents and children. Findings are that where both parents are motivated primarily by interest in the child, where the parenting is sensitive and where the child is shielded from interparental conflict, young children do well. Such families were not the majority in this study. Significant differences emerged in the adjustment of the 1–3 age group as compared with the 3–5 age group which point to greater difficulties for the 3–5 year-olds. 相似文献

Samples of blue and red cotton fibres were examined using light and fluorescence microscopy as well as UV/VIS microspectrophotometry and fluorescence microspectroscopy. The degree of fluorescence and spectral variation was recorded. Particular attention was paid to the recurrence of certain spectral patterns. The importance of spectral information in the UV range is emphasized again. Colour plays a critical role in the comparison of cotton fibres in forensic sciences. Normally, fibres producing spectral patterns that are frequently seen will tend to have a lower evidential value in criminal cases as the choice of putative sources is theoretically greater and vice versa. Besides black cotton, blue and red cotton fibres are very frequent in fibre casework. The very high discriminating power using a combination of light microscopy, fluorescence microscopy and UV/VIS microspectrophotometry shows that even blue and red cotton fibres can provide excellent evidence when involved in fibre transfer cases. 相似文献
