Few studies consider how Putnam’s bridging and bonding social capital arguments apply to voluntary associations within American minority group communities. Consequently, I examine African-American civic groups to explore Putnam’s claims about the potential negative political effects of bonding social capital. In contrast to the bonding social capital thesis, I argue that black communal associations encourage African-Americans to be involved in a variety of mainstream civic and political activities that reach beyond their own group interests. Using the 1993–1994 National Black Politics Study I demonstrate that although black organizations are predominantly composed of African-Americans and work to advance their interests, these goals are not pursued at the expense of connecting blacks to others in the general polity.

Compound-specific isotope analysis offers potential for fingerprinting of diesel fuels, however, possible confounding effects of isotopic fractionation due to evaporation need to be assessed. This study measured the fractionation of the stable carbon and hydrogen isotopes in n-alkane compounds in neat diesel fuel during evaporation. Isotope ratios were measured using a continuous flow gas chromatograph/isotope ratio mass spectrometer. Diesel samples were progressively evaporated at 24 ± 2°C for 21 days. Increasing depletion of deuterium in nC12nC17 alkanes in the remaining liquid with increasing carbon chain length was observed. Negligible carbon isotope fractionation was observed. Preferential vaporization was measured for the shorter chain n-alkanes and the trend decreased with increasing chain length. The decrease in δ2H values indicates the preferential vaporization of the isotopically heavier species consistent with available quantitative data for hydrocarbons. These results are most important in the application of stable isotope technology to forensic analysis of diesel.  相似文献

World trade is increasingly conditioned by the rules of the World Trade Organisation. In the case of the garment industry this means the phasing out of the Multifibre Arrangement, which has dominated trade in textiles and garments since 1974. This phase-out is seen as benefiting developing countries and criticism focuses on the manner in which the USA and Europe are holding up the process. However, it is important to look at who exactly will gain or lose. Not all poor countries will benefit. Furthermore, the main profits from garment production go to the Northern companies who control the industry. These companies will benefit from more open markets and associated competition between global suppliers. Meanwhile, for workers North and South, this increased competition brings insecurity and the threat of deteriorating conditions of work.  相似文献

Popular ideas concerning serial murder see these killings as an act committed by a deranged or irrational individual. This article contends that this is not the case, but that the killer is behaving in a manner which makes sense and is logical to the killer and is a response to some perceived wrong. The process through which this reponse occurs is detailed. The conclusion suggests that if serial murder is indeed a learned response then this response can be “unlearned” and the serial murderer can be restored to again function within society.  相似文献

This article examines two Buddhist explanations of how a conceptual cognition, whose object is a universal, can give rise to activity that leads to a particular. In both theories, that of Dharmottara and that of Ratnakīrti, this activity is due to a kind of error. A detailed investigation of how this error happens shows that there were big differences in the two underlying epistemological models.  相似文献

The field of mental health offers a valuable context in which to examine new challenges presented by human genetic research databases to the legal, ethical and regulatory frameworks for human genetic research. Longitudinal prospective genetic research of psychiatric disorders often involves access to human genetic research databases and to stored tissue for future uses that cannot be specified at the time the patient consents to their collection. The potential of such research to contribute to an improved understanding and treatment of complex genetic diseases such as schizophrenia presupposes sound ethical, legal and regulatory frameworks to ensure public trust and preparedness to participate in such research. This article provides a brief overview of some of the ethical and legal challenges posed by human genetic research databases and their implications for how genetic research should be conducted in the field of mental health.  相似文献
