All adoptions, including those facilitated by public agencies, should be evaluated for openness. Although there are no national figures related to openness in public welfare, there are indications that it is not considered in all cases. Adoption myths may be one of the reasons that adoption workers do not always assess a family's ability to maintain a more open adoption arrangement. The following study is the initial validation of a multidimensional psychometric instrument developed to measure myths as they relate to open adoption. Based on a sample of 547 university students, the results indicate very good reliability and acceptable factorial and construct validity. The instrument was designed as a training and research tool to inform child welfare personnel and policy makers of the influence of adoption-related myths on child welfare adoption practice. 相似文献

This article seeks to identify factors associated with the formation and development of nonmetropolitan destinations for older in‐migration, thereby explaining why some U.S. counties are more likely than others to be nonmetro retirement destinations. We contend that most nonmetro retirement destinations are established and developed over time through a path‐dependent process. When amenities are commodified as recreation and tourism, migration streams tend to be established that ultimately produce sustained in‐migration of older persons to selected destination communities. We use data from a variety of official sources and a spatial statistics methodology to examine intercounty variability in net migration rates at ages 60–74. Our findings are consistent with the aforementioned path‐dependent development framework. Counties with a long history of population growth, previous experience attracting older in‐migrants, attractive natural amenities, and a developed recreation and tourism industry are those most likely to be retirement‐age migration destinations. In contrast, agricultural heartland and relatively large population size are associated with lower rates of older in‐migration. Older in‐migration should be seen as neither a panacea for strapped rural communities nor a “pensions and care issue.” Older migrants can be “gray gold,” but they can also pose challenges, such as possibly increased demand for public services as they age in place. 相似文献

This article describes estimation and inference procedures for the parameters of the Box-Cox and foided-power transformations in repeated measures and growth curve models. Procedures for computing maximum likelihood estimates of the transformation and covariance parameters under several covanance structures (omnibus sphericity, local sphericity, and unstructured) are described. Lack of fit statistics and hypothesis tests for comparing these structures also are described. The procedures are illustrated on three data sets. Software for performing the analyses in the SAS System is described and is available from the authors. 相似文献

Research in the United States has shown that children growing up in 2‐parent households do better in school than children from single‐parent households. We used the Trends in International Mathematics and Science Study (TIMSS) data to test whether this finding applied to other countries as well (N = 100,307). We found that it did, but that the educational gap was greater in the United States than in the other 13 countries considered. Results from 2‐level hierarchical linear models demonstrated that international differences in the educational gap were associated with several indicators of national policy and demographic contexts. No single policy appeared to have a large effect, but several policy combinations were associated with substantially reduced educational gaps between children from different family structures. 相似文献

This paper presents a critical review of the most frequently cited resurgence of ethnicity studies. Many of the sources cited in recently published ethnic relations books are found to lack an empirical base. They are essentially polemical, impressionistic and anecdotal works. Empirical studies that support the resurgence of ethnicity theme are also examined. Their shortcomings are noted. Nevertheless, these empirical studies provide convincing evidence that ethnic differences persist into the later generations. Overall, however, the empirical studies overwhelmingly document increasing assimilation. Virtually no evidence is found for the notion of a third generation resurgence. 相似文献

In the face of administrative and pedagogic changes in professional social work training, educators and trainers face considerable uncertainty. Key dilemmas concern what is meant by competence, and how far it is possible to identify and reconcile technical and ideological competencies. This paper uses empirical material from a semi-participant study to explore the relevance of the concept ‘cloak of competence’, with reference to the behaviour of tutors and practice teachers. It suggests that excessive or continuous uncertainty generates avoidance or coping strategies, which lead to a resolution by the achievement of an appearance of competence. The consequences of these processes for staff development are then briefly considered. 相似文献
