This study focuses on the role of family experience in adolescents' conception of the self in the context of friendship and dating relationships. Three issues are addressed: the extent of sex differences in adolescents' friendship and dating identity, how links between family experience and friendship and dating identity might differ for males and females, and whether mothers and fathers play distinctive roles in such development. A sample of Caucasian two-parent families, each including an adolescent who was a high school senior, was observed in a family interaction task designed to elicit the expression and coordination of a variety of points of view. Each adolescent was also given an interview assessing exploration and commitment in friendship and dating identity. Only one sex difference was found in identity, with females more committed in their conceptions of dating relationships than males. The key finding of the study concerns the distinctive patterns of family interaction associated with friendship and dating identity. For females, separateness in family interaction was related to their friendship identity exploration, whereas for males, the links between family interaction and exploration all involved connectedness. The different contingencies may reflect the interplay between different societal patterns of support and restriction of males' and females' exploration.This work was supported by grants from the National Institute of Child Health and Human Development (HD-92819 and HD-17983) and the Hogg Foundation for Mental Health and from the University Research Institute and the Institute of Human Development and Family Studies of the University of Texas at Austin.Received her Ph.D. in child psychology from the University of Minnesota.

Prior research has linked the innovative behavior of public sector employees to desirable outcomes such as improved efficiency and higher public service quality. However, questions regarding the drivers of innovative behavior among employees have received limited attention. This article employs psychological empowerment theory to examine the underlying processes by which entrepreneurial leadership and public service motivation (PSM) shape innovative behavior among civil servants. Based on three‐wave data from 281 Chinese civil servants and their 59 department heads, entrepreneurial leadership is found to positively influence subordinates' innovative behavior by enhancing two dimensions of psychological empowerment: meaning and impact. Additionally, PSM was found to influence subordinates' innovative behavior by enhancing the dimensions of meaning and competence. These findings suggest that to facilitate innovative behavior among employees, public organizations should consider introducing training that encourages leaders to serve as entrepreneurial role models and recruit employees with high levels of PSM.  相似文献

This article considers some salient theoretical contributions which bear upon our understanding of the Common Fisheries Policy (CFP) of the European Union (EU). It outlines the fundamental dilemma highlighted in game theory known as 'the tragedy of the commons' and goes on to examine whether the CFP can be construed as a 'policy fiasco'. The article considers how the fisheries of the EU could be more effectively managed and underlines the urgent need for international collective action. With the mismatch between the CFP and the scale of the problem it is intended to address firmly in sight, the article concludes with an evaluation and some policy suggestions.  相似文献

The concept of "community councils" is one which has gained increasing prominence in Scottish local government during the last few years. Their main function is simply to advise local councillors on the views of the local community. Our basic contention is that the local government system in New South Wales (and, probably, other states) could benefit from studying the Scottish experience.  相似文献

The purpose of these studies was to evaluate the performance characteristics of the Cozart Microplate Enzyme Immunoassay (EIA) for the determination of methadone in oral fluid from patients in a drug misuse treatment program. Oral fluid specimens were collected using the Cozart RapiScan Collection system from 198 donors who were receiving treatment for their addiction and were monitored for drug misuse. Oral fluid specimens were also collected from forty volunteer donors who were not drug users. The specimens were analyzed in the laboratory by EIA and then analysed for methadone and its main metabolite EDDP by gas chromatography-mass spectrometry (GC-MS). A total of 103 samples were confirmed positive for methadone. The Cozart Microplate EIA for d-Methadone in oral fluid using a cutoff of 30 ng/mL in diluted oral fluid had a sensitivity of 91.3% +/- 2.8% and a specificity of 100% +/- 1.0% vs. GC-MS.  相似文献

At the annual meeting of the Society of Hair Testing in Vadstena, Sweden in 2006, a committee was appointed to address the issue of guidelines for hair testing and to assess the current status of accreditation amongst laboratories offering drug testing in hair. A short questionnaire was circulated amongst the membership and interested parties. Fifty-two responses were received from hair testing laboratories providing details on the amount and type of hair tests they offered and the status of accreditation within their facilities. Although the vast majority of laboratories follow current guidelines (83%), only nine laboratories were accredited to ISO/IEC 17025 for hair testing. A significant number of laboratories reporting that they were in the process of developing quality systems with a view to accrediting their methods within 2-3 years. This study provides an insight into the status of accreditation in hair testing laboratories and supports the need for guidelines to encourage best practice.  相似文献
