Students with college educated parents are more likely to attain higher levels of education than students of parents with lower levels of education. Past research has explained this favorable outcome as the result of advantageous placement and greater availability of educational resources. Using data from Add Health and AHAA, we find evidence that exposure to students of college educated parents at the school level and within courses increase the likelihood of four year college enrollment even after controlling for family background, achievement, and placement. We also found that exposure to students of college educated parents has especially strong positive effects on college enrollment for students whose own parents do not have a college degree. These findings suggest that greater exposure to students of highly educated parents at the school level and within courses partially explains the favorable educational attainment of students with college educated parents. 相似文献

This paper presents a case study of the research and development of an RFID‐based traceability system in an aircraft engineering company in Hong Kong. We report the system design and implementation, and discuss our experiences and lessons learned. The aim of the RFID system is to effectively support the tracking and tracing of aeroplane repairable items in the company. The study reveals eight critical success factors for the successful implementation of RFID systems, namely, create strong internal and external motivation for improvement, stir up desire to keep abreast of the latest technology for global competitiveness, strive for cross organizational implementation, avoid major process changes/limit process changes, start with a small RFID project scope, facilitate equipment vendor's investment, use cost‐effectiveness reusable tags, and transfer RFID skills and knowledge from university to industry. We also summarize 13 lessons learned, including three lessons concerning RFID implementation at strategic level, six lessons at management level, and four lessons at operational level resulting from carrying out this project. Given the contextual details of the study, the lessons learned can help other firms to better anticipate the hurdles they will experience, and make them aware of the possible ways to cope with such difficulties before embarking on the journey of RFID implementation. 相似文献

This paper contains results of a study into changes in rates of suicide in Australia in the 1970s and 1980s. The study found that there was a significant divergence of suicide mortality rates between males and females, with male rates increasing in the last twenty years and female rates showing a general decline. The increase in male rates was highest at ages under 30 and over 80 years of age. The differences in rates between marital status groups have remained large. The study also analysed birthplace differentials in suicides and included some data from overseas countries for comparisons. 相似文献

Because many communities where older people live were not designed for their needs, older residents may require support to remain in the least restrictive environment. "Age-prepared communities" utilize community planning and advocacy to foster aging in place. "Elder-friendly communities" are places that actively involve, value, and support older adults, both active and frail, with infrastructure and services that effectively accommodate their changing needs. This paper presents an analysis of the literature and results of a Delphi study identifying the most important characteristics of an elder-friendly community: accessible and affordable transportation, housing, health care, safety, and community involvement opportunities. We also highlight innovative programs and identify how social workers can be instrumental in developing elder-friendly communities. 相似文献

Hispanics are now the largest minority group in the United States and their presence is likely to continue to expand. Little is known, however, about the correlates of Hispanic identity or the processes that are involved in its maintenance. We investigate these issues by ascertaining and then seeking to understand the various associations between reported racial identities and Hispanic ethnicity using data from the Current Population Surveys. Restricting the sample to individuals who are known to have demographic origins in Latin America, our results indicate that persons with African or Asian racial identifications are substantially less likely than whites or Others to also identify as Hispanic. Relative to the first generation, Hispanic identification declines and the racial differences increase in the second generation. The exceptions in this regard are Others for whom racial and Hispanic identifications are the most highly associated for both the first and second generations. These findings are interpreted as reflecting various social processes that are involved in the development and maintenance of racial and ethnic identities. Our results provide insight into the complex, social nature of Hispanic identification in modern America. 相似文献

Utilizing data from the 1992–1994 Health and Retirement Study (HRS), this paper examines the question of whether three groups of older working-age women—childless women, mothers with at least one child at home or temporarily away at school, and mothers with all their children living away from home—were different or similar in their likelihood of retirement and their actual work status. The results show that the childless group and the child-not-at-home group were more likely than the child-at-home group to define themselves as retired, although the three groups were equally likely to engage in paid work activities. Both early childbearing history and ongoing parental financial obligations appear to influence women's willingness to assume a retiree versus a nonretiree status. The findings may reflect an emerging trend of retirement being a status symbol rather than a marker of complete cessation from the world of work. 相似文献
