Intergenerational relations among in-laws are involuntary ties emerging as a consequence of marriage. As such, these relations provide a window through which the dynamics involved in restructuring social networks following life transitions may be observed. A questionnaire, based on the social convoy model, was given to an ethnically diverse sample of adults with living in-laws (N = 170), married 2–15 years. About half of the respondents included in-laws in a concentric circle network diagram of persons close and important to them. The strongest unique predictors of convoy placement for the mother-in-law were support, frequency of contact, relationship quality, and length of marriage, and for the father-in-law were support, relationship quality, and value similarity. This study sheds light on the dynamics of an intergenerational relationship that has been largely ignored in the literature, laying the groundwork for conceptualizing ways to foster positive in-law relationships as a necessary tool in managing the care of the growing numbers of elderly in the new millennium. 相似文献

We present a hypothetical case study using the Years of Potential Life Lost (YPLL) metric to compare cancer risks incurred by residents living near a Superfund site to occupational fatality risks incurred by workers employed in that site's remediation. Since cancer occurs late in life, and because we assume its mortality rate is 60%, each case results in 8.8 YPLL. Each occupational fatality, which typically occurs earlier in life, results in 38.1 YPLL. In our case study, the residential population of 5000 incurred 1.3 YPLL, compared to 5.7 YPLL incurred by the 500 workers. Several uncertain assumptions may influence our calculations; moreover, occupational risks may be viewed as more "voluntary" than risks incurred by residents. However, because the magnitude of the YPLL incurred by workers and residents may be comparable, risk managers should consider occupational risks when evaluating remedial alternatives. 相似文献

We consider statistical inference on parameters of a distribution when only pooled data are observed. A moment-based estimating equation approach is proposed to deal with situations where likelihood functions based on pooled data are difficult to work with. We outline the method to obtain estimates and test statistics of the parameters of interest in the general setting. We demonstrate the approach on the family of distributions generated by the Box-Cox transformation model, and, in the process, construct tests for goodness of fit based on the pooled data. 相似文献

At one level, private practice may represent a fairly evolved manifestation of the expanded professional growth and sophistication of the individual social worker who embarks upon this highly individualized proprietary enterprise. However, on a larger scale, this widespread shift toward private practice may indicate a collective disenchantment with agency practice per se and represent a concerted attempt to redefine the fundamental aims and values of social work practice. 相似文献

In this paper a method for the construction of a class of row-column designs with good statistical properties and high efficiency is presented. The class of designs produced is shown to exhibit balance, orthogonality and adjusted orthogonality. The efficiencies of these designs are investigated in detail, and they are shown to be very high, and possibly maximal in some cases. 相似文献

Two potential problems in sex surveys—respondent refusalsand invalid reporting—are examined for national and areaprobability samples of males and females. Little support isfound for the contention that sexual topics constitute a sensitiveresearch area in terms of respondent cooperation and candor.It is found that (1) respondent cooperation, as indicated byrefusals and terminations, is neither more nor less problematicin sex research than in surveys on other topics; (2) respondentreports of sexual matters are not systematically related tointerviewer characteristics such as gender, sexual experience,or technical competence; (3) respondent candor, when self-reported,also is not associated systematically with either interviewercharacteristics or demographic and sexual characteristics ofrespondents. This analysis does identify, however, evidencethat (4) sexual matters often are sensitive topics for interviewersand principal investigators, leading both to interviewer turnoverand the creative construction of unobtrusive data collectionprocedures. 相似文献
