The objective of this article is to assess the effect of abuse cessation on depressive symptoms among women abused by a male intimate partner. This prospective cohort study of Seattle women with a history of intimate partner violence (IPV) who were classified by history of abuse and abuse status at 3 month, 9 month, and 2 year follow-up interviews. Relative risks (RR) were calculated using generalized estimating equations. Among subjects with a history of psychological abuse only, cessation of abuse was associated with a nonsignificant reduction in the likelihood of depression compared to subjects whose abuse continued (aRR = 0.88; 95%CI: 0.75,1.03). Among subjects with a history of physical/sexual abuse and psychological abuse, cessation of physical/sexual abuse only was associated with a 27% decline, and cessation of both types of abuse was associated with a 35% decline in the likelihood of depression (aRR = 0.73, 95%CI: 0.63,0.86; and aRR = 0.65; 95%CI: 0.55,0.76; respectively). Cessation of abuse among victims of IPV is associated with a decreased prevalence of depression. 相似文献

We identify managerial challenges offered by an emergent nanotechnology innovation system in which knowledge is dispersed, asymmetric and contested. We argue the proposed models of knowledge absorption and transformation enhance existing theories of knowledge and emergent technology by recognizing how and why knowledge flows among the actors in emergent technology innovation system. We base our argument on combined research evidence from a Delphi study concerning the future of European manufacturing, from which a selected statement has been analyzed, and from analysis of the NanoManufacturing Institute at Leeds University, UK; specifically its work in building ties between different actors associated with nanotechnology. We conclude our paper with suggestions for future research. 相似文献

A study of industrial engineering in seven European countries was carried out for the purpose of comparing European organization and practice in that field with the American situation as revealed by an earlier survey. The data obtained relate to organizational variables such as distinctiveness, location, degree of centralization and contact with headquarters; staffing factors such as number of personnel and their education, and the use made of specified techniques. Changes and trends in these terms are then explained. The data suggest that Europe and the U.S. are essentially similar. Finally, the future of industrial engineering is explained in terms of the demands which will be made on industry and the contribution which industrial engineering can make to meeting these. 相似文献

SUMMARY A method for comparing groupings of DNA sequences is presented, which utilizes randomization test methods to assign significance levels to a test statistic defined in terms of the Hamming distance between two sequences. The method, which is intuitively motivated by the analysis of variance procedure, partitions the variation caused by differences between clusters from the variation attributable to differences at random base pair locations within clusers. Implementation issues are discussed, and an example of the application of the method is provided. 相似文献

The article provides evidence that there is a relationship between government debt and interest rates via the demand for money. This relationship is examined through the wealth effect of government debt on money demand, and the robustness of the results is tested by the use of extreme bound analysis in addition to standard econometric techniques. We find that OLS regression shows government debt fnfecting the demand for money positively, implying that Federal government debt is net wealth. In addition, the extreme bound analysis shows that the estimates of the government debt coefficient are robust under alternative specifications of the Goldfeld model. 相似文献

Proponents of the view that social structures are ontologically distinct from the people in whose actions they are immanent have assumed that structures can stand in causal relations to individual practices. Were causality to be no more than Humean concomitance correlations between structure and practices would be unproblematic. But two prominent advocates of the ontological account of structures, Bhaskar and Giddens, have also espoused a powers theory of causality. According to that theory causation is brought about by the activity of particulars, in the social psychological case, individuals of some sort. Consistence would demand that structure be those individuals. But neither Giddens nor Bhaskar wish to reify structure to the extent that would fit it for a role as a powerful particular. If only human beings can be powerful particulars in these contexts, the only way that structures can be real must be as properties of conversational (symbolic) interactions. Human action is social just in so far as people direct themselves to engage well in joint activities with others. 相似文献

"When we first saw the draft act, we were dismayed." The new Act for the independence of official statistics has now passed into law. Is the Royal Statistical Society (RSS) still dismayed? Tim Holt , President of the RSS, explains the Act, its workings, how parts of it have been changed for the better and what concerns still remain. 相似文献
