The authors review the trends in the use of computers in the delivery and support of career guidance and counseling identified at the symposium International Perspectives on Career Development. The papers presented emphasized that 20th‐century computer‐based systems continue to be used, mainly delivered via the World Wide Web. These systems are enhanced through audio, video, graphics, strategies to provide needs assessment, and support by cybercounselors or expert system design. The papers also revealed a new trend: the use of elegant Web sites to store and search immense libraries of resources needed by professionals and clients and to facilitate communication and collaboration among professionals in cyberspace. Concerns, issues, and resources related to many areas, including the readiness of clients to use computer‐based systems, were also raised; existing sources of guidelines are noted. 相似文献

A growing literature examines the empirical relationship between the joint reproductive preferences of marital partners and reproductive outcomes in Africa. Less explored is how spousal power in decision making may be influenced by lineage type. Using pooled data from Ghana, we investigate how lineage affects gendered reproductive decision outcomes and find some evidence that matrilineal women are more able than nonmatrilineal women to translate their reproductive preferences into action consistent with their goals. 相似文献

Using data from 8 random assignment studies and employing meta‐analytic techniques, this article provides systematic evidence that welfare and work policies targeted at low‐income parents have small adverse effects on some school outcomes among adolescents ages 12 to 18 years at follow‐up. These adverse effects were observed mostly for school performance outcomes and occurred in programs that required mothers to work or participate in employment‐related activities and those that encouraged mothers to work voluntarily. The most pronounced negative effects on school outcomes occurred for the group of adolescents who had a younger sibling, possibly because of the increased home and sibling care responsibilities they assumed as their mothers increased their employment. 相似文献

In this article I examine some of the problems that ‘modern’ legal theory poses for a consideration of the extended reach of social actors and institutions in time and space. While jurisprudence has begun to engage with the concept of globalization, it has done so in a relatively limited manner. Thus legal theory's encounters with highly visible transnational practices have, for the most part, resulted not in challenging the prevailing formal legal paradigm, but in a renewed if slightly modified search for a general jurisprudence that ultimately takes little account of the manner in which the work of law is carried out transnationally. In the first part of this article I examine how legal theory's concern to maintain its own integrity places limitations on its ability to examine the permeability of social boundaries. In the latter part I draw on critical human geography, post–structuralism and actor–network theory (ANT), to examine the manner in which transnational actors have been able to mobilize law, and in particular intellectual property rights (IPRs), as a necessary strategy for both maintaining the meanings of bio–technologies through time and space, and enrolling farmers into particular social networks. 相似文献

We examine how yardstick competition between jurisdictions affects the agency problem resulting from uncertainty about politicians (adverse selection) and their policies (moral hazard). We find that yardstick comparison can contribute both to disciplining and to selecting politicians.Earlier versions of this paper have circulated as Queen Mary Working Paper No. 444 and CORE Discussion Paper 2002/29. We would like to thank our editor, Maurice Salles, two anonymous referees, Mark Armstrong and Enrico Minelli for helpful comments and suggestions. We would also like to thank seminar participants at CORE, Queen Mary, Marseilles, and the 2002 Public Economic Theory conference, Université Paris 1. 相似文献

Which is the ‘self’ in ‘self‐interest’? 总被引:1,自引:0,他引:1
Paul duGay 《The Sociological review》2005,53(3):391-411
This article contends that homogenisation of the term ‘self‐interest’– in sociological and economic discourse – has resulted in many misconceptions about what particular doctrines of ‘self‐interest’ were instituted to achieve at certain historical periods and in specific cultural milieux. At its worst, the article argues, this has led to a misunderstanding of the import of particular doctrines of self interest,which are read in terms of general tradition – such as that which views self‐interested conduct as a natural faculty – rather than in terms of the context specific aims of those advocating them. The article attempts to show how, historically, there have been quite significant changes in the characterisation of the ‘self’ deemed to be ‘self‐interested’. In particular, it focuses on the ‘self’ of certain early modern conceptions of self interest, and suggests this creation is best viewed not as a subjectivity transcendentally presupposed by experience, but as one historically cultivated to counter the exigencies of particular circumstances – the disaster of perpetual ‘warre’ in 17th century Europe – and to meet the purposes of a certain way of life – existence in the civitas. 相似文献

A controlled clinical trial was conducted to investigate the efficacy effect of a chemical compound in the treatment of Premenstrual Dysphoric Disorder (PMDD). The data from the trial showed a non-monotone pattern of missing data and an ante-dependence covariance structure. A new analytical method for imputing the missing data with the ante-dependence covariance is proposed. The PMDD data are analysed by the non-imputation method and two imputation methods: the proposed method and the MCMC method. 相似文献
