In some areas in Sub‐Saharan Africa, a rural proletariat has emerged, mainly consisting of labourers living and working on plantations and large mixed farms. Besides these ‘full proletarians’, there are also labourers living outside the agricultural estates who perform agricultural wage labour during specific seasons only. Most of these ‘semi‐proletarians’ own a small piece of land. The study analyses the relationship between the degree of proletarianisation on the one hand, and the socio‐economic situation and living conditions of labourers on large farms in Kenya's Trans Nzoia District on the other. In doing so, a comparison is also made with a group of non‐labourers. The conclusion is that a higher degree of proletarianisation coincides with a lower income level but not necessarily poorer living conditions. 相似文献

Community college students (N=170) were surveyed regarding the intensity and frequency of methods of corporal punishment they have received and the persons administering the punishment. Results indicate that corporal punishment is a normatively used method of behavioral management. Males reported receiving a greater amount of corporal punishment, especially from their fathers. Overall, those who received a high amount of corporal punishment reported lower grades and a significantly greater number of problems, such as aggression, delinquency, depression, and anxiety. These findings are cause for concern and intervention.Received Ph.D. in psychology from Tufts University.

This article focuses on the phenomenon of elder abuse, which is one of the paramount symptoms of the larger community's failure to address the social, medical, and legal needs of the senior populace. Although there have been multidisciplinary efforts to address this problem, they are not responsive to the needs of the senior population itself In response, the authors propose a model that takes into account the specific concerns of local senior communities and provides seniors and their stakeholder providers a stable infrastructure to ensure open, consistent, and effective participation and delivery of services. 相似文献

Eye tracking was used to measure visual attention of nine forensic document examiners (FDEs) and 12 control subjects on a blind signature comparison trial. Subjects evaluated 32 questioned signatures (16 genuine, eight disguised, and eight forged) which were compared, on screen, with four known signatures of the specimen provider while their eye movements, response times, and opinions were recorded. FDEs' opinions were significantly more accurate than controls, providing further evidence of FDE expertise. Both control and FDE subjects looked at signature features in a very similar way and the difference in the accuracy of their opinions can be accounted for by different cognitive processing of the visual information that they extract from the images. In a separate experiment the FDEs re-examined a reordered set of the same 32 questioned signatures. In this phase each signature was presented for only 100 msec to test if eye movements are relevant in forming opinions; performance significantly dropped, but not to chance levels indicating that the examination process comprises a combination of both global and local feature extraction strategies. 相似文献

Traditionally identification of forensically important insects has been carried out based upon morphological differences between species. However insect evidence found at a crime scene may on occasion be difficult to distinguish by morphological techniques and under these circumstances another method of accurate identification is required. This work utilises a cytochrome oxidase I partial mitochondrial gene region (COI) to distinguish the two of the main UK blowfly species -- Calliphora vicina (Robineau Desvoidy) and Calliphora vomitoria (Linnaeus) (Diptera:Calliphoridae). Seventeen interspecific differences in COI sequence were located. Use of the restriction enzyme SfcI on this gene region provides a simple method for distinguishing between C. vicina and C. vomitoria. 相似文献
