An investigation of residences located above dry cleaning facilities was conducted to determine whether indoor and outdoor air concentrations of the dry cleaning solvent tetrachloroethene (perchloroethylene, PCE) were elevated compared to residences not near a dry cleaning facility. Data were also collected on the dry cleaners' operating conditions and equipment. Significantly elevated levels of PCE were found in the indoor air of each of six apartments located above dry cleaners compared to control residences for both day and night samples. The PCE concentrations in outdoor air near the dry cleaners were also significantly elevated compared to control locations and were lower than the concentrations measured indoors. The type of dry cleaning machine was significantly associated with the concentration of PCE found in the apartment above. A strong correlation was also found between the day and night PCE levels in the study apartments.  相似文献

One hundred couples were followed for 13 years from the premarital period well through the primary risk period for divorce. Results of discriminant analysis indicated that couples who remain satisfied, become distressed, and divorce can be reliably classified on the basis of premarital data. Further, both previously identified demographic risk factors and couple interaction variables contributed to classification accuracy, suggesting that both types of variables play important roles in relationship outcomes. The method employed here addresses weakness in previous studies by: (a) following couples for an extended period after marriage, (b) using multiple validated self‐report and observational measures, and (c) making predictions simultaneously for divorced, distressed, and satisfied couples.  相似文献

Most migration statistics in the United States focus on changes in permanent residence, thereby missing temporary moves such as the daily commute to work, business trips, vacations, and seasonal migration. In this paper, we analyze temporary migration streams in Florida, focusing on moves that include an extended stay. Using several types of survey data, we examine the characteristics of non-Floridians who spend part of the year in Florida and Floridians who spend part of the year elsewhere. We develop estimates of the number, timing, and duration of temporary moves and the origins, destinations, characteristics, and motivations of temporary migrants. This study presents the most comprehensive analysis yet of temporary migration in Florida and provides a model that can be used in other places. It also points to a serious shortcoming in the US statistical system, namely, the lack of information on temporary migration streams. We believe the American Community Survey provides an opportunity to remedy this problem.  相似文献

The demographic transformation and the sociological enterprise   总被引:1,自引:1,他引:0  
The dramatic demographic changes of the 1980s and 1990s in the United States are creating a multiracial, multicultural society. This article examines the intellectual challenges for sociology posed by the emerging racial diversity brought about by these population trends. The problem is that conventional sociological frameworks no longer apply in this increasingly complex social world of rapid population changes, diversity, and polarization. Most significant, conventional American sociology, which has focused on white society rooted in western culture, is challenged by three large racial/ethnic categories. We argue that diversity must be incorporated into our sociologies. This requires two new approaches: (1) Sociology must be recentered, that is, it must move away from the notion that whites have the universal experience against which all others are measured; and (2) Sociologists must apply to diverse populations the same kind of sociological analysis that they apply to mainstream categories. This means that we demythologize by dispelling common myths about those outside the mainstream and that we uncover the mechanisms that construct social differences.  相似文献

Teenage pregnancy has become a major policy issue, for which young people are often publicly held solely responsible. However, a combination of factors substantially increases the risks of conception faced by young people engaging in early sexual activity. This article reports the main findings of a study of teenage pregnancy in linked seaside and rural areas, focusing on the experiences and perceptions of young people living in rural localities. They identify the issues of immobility, visibility and attitudes of stigma as affecting their ability to access sexual health services. The young people highlighted issues for service and policy development and the behaviour of professionals, both within schools and from sexual health services. Education, social and health services and the voluntary sector have important roles to play in responding to their needs.  相似文献

Changes in Telephone Survey Nonresponse over the Past Quarter Century   总被引:23,自引:8,他引:15  
We correct, update, and elaborate Curtin, Presser, and Singer’s(2000) report that the University of Michigan’s Surveyof Consumer Attitudes (SCA) experienced only a small responserate decline between 1979 and 1996, contrary to the widespreadperception of plunging response rates. Our aims are to (1) correcterrors in the SCA response rate data that affected Curtin, Presser,and Singer’s (2000) result, (2) examine the trend in SCAresponse rates after 1996, when caller identification technologybecame widespread, and (3) describe the roles played by thevarious sources of SCA nonresponse over time. The results showthat the response rate decline from 1979 to 1996 was largerthan described by Curtin, Presser, and Singer (2000); the responserate drop was significantly steeper from 1996 to 2003 than from1979 to 1996; and the 1979 to 2003 trends differed substantiallyfor refusals and noncontacts.  相似文献

This article examines the issues arising from student placements in the private or commercial sector. It focuses on private residential care for adults, as the most developed area of private provision in the UK, and explores the background to this form of provision. The article then considers the private sector placement from the viewpoints of the student, the private sector agency and the educational institution. A checklist for social work educators considering placements in the private sector draws together some of the key issues. The article ends with a discussion of the pragmatic, moral, logistic and educational perspectives which influence attitudes towards the private sector.  相似文献
