This grounded theory study of 16 Mexican immigrant adolescents and 20 of their parents examines how they construct relational identities within their families, at school, with friends, and in the larger society. Results focus on a core identity bind faced by the adolescents: immigration messages from parents that say, “don't be like me” and the societal message, “you're not like us.” Response to this bind was guided by two contrasting sets of identity narratives: Empowering narratives invited an intentional approach to school and life choices. Restricting narratives maintained an ambivalent approach to school and life choices. Resolution of the identity bind was a collective, ongoing process that has implications for Mexican immigrant families and the professionals who work with them.  相似文献

The Revised Dyadic Adjustment Scale (RDAS; Busby, Crane, Larson, & Christensen, 1995) is a measure of couple relationship adjustment that is often used to differentiate between distressed and non‐distressed couples. While the measure currently allows for a determination of whether group mean scores change significantly across administrations, it lacks the ability to determine whether an individual's change in dyadic adjustment is clinically significant. This study addresses this limitation by establishing a cutoff of 47.31 and reliable change index of 11.58 for the RDAS by pooling data across multiple community and clinical samples. An individual whose score on the RDAS moves across the cutoff changes by 12 or more points can be classified as experiencing clinically significant change.  相似文献

Numerous scholars documented declines in America's social capital through the mid‐1990s but we do not know whether the trend has continued. Further, despite warnings by Robert Putnam and Theda Skocpol that the quality of Americans' voluntary association memberships has also deteriorated—moving from active, “face‐to‐face” memberships to passive, “checkbook” memberships—data have not been available to test this claim. In this article, we use both the Iowa Community Survey and the General Social Survey to explore the changing nature of voluntary association membership between 1994 and 2004. We demonstrate that not only are declines in voluntary association memberships continuing in the new century but there has been a shift in the intensity of voluntary association participation over time. We observe a decline in active membership over time and an increase in checkbook membership over time. These findings provide support for Putnam's claim that checkbook membership is increasing at the expense of more active types of memberships.  相似文献

Gender integration within science has been uneven: some fields have integrated women to almost equitable levels, while others remain male‐dominated. Explanations for this variation abound, but few are able to assess empirically the relevance of disciplinary cultures in a systematic way. We take up this challenge by analysing accounts of scientific success in fields that integrated women to a large degree (Psychology and the Life Sciences) and fields that did not (Engineering and Physics). We qualitatively assess how the salience of relationships changed over time in these fields. We find that scientists from disciplines that have crossed the threshold whereby women are no longer tokens culturally value informal relationships more than those in which women remain a small numerical minority.  相似文献

This paper considers the problem of selecting matched pairs of observations for the reduction of bias in statistical hypothesis testing. A Euclidean distance function is suggested for measuring the similarity between paired observations. The matching process is then formulated initially as an assignment problem. Alternative formulations of the problem that would reduce computational difficulty are considered.  相似文献

This study explores the motivational consequences of an incentive device based on standard setting. It is shown that standard setting induces a wealth-seeking manager to undertake decisions that, in the manager's judgment, will improve the position of the owner relative to implementing the standard. Conditions under which it is rational for the owner to allow the manager to choose and implement decisions are discussed. Finally, consideration is given to an alternative incentive mechanism in which the manager's decisions are manipulated through variation of the incentive mechanism.  相似文献

Thirty empirically assessed utility functions on changes in wealth or return on investment were examined for general features and susceptability to fits by linear, power, and exponential functions. Separate fits were made to below-target data and above-target data. The usual “target” was the no-change point. The majority of below-target functions were risk seeking; the majority of above-target functions were risk averse; and the most common composite shape was convex-concave, or risk seeking in losses and risk averse in gains. The least common composite was concave-concave. Below-target utility was generally steeper than above-target utility with a median below-to-above slope ratio of about 4.8. The power and exponential fits were substantially better than the linear fits. Power functions gave the best fits in the majority of convex below-target and concave above-target cases, and exponential functions gave the best fits in the majority of concave below-target and convex above-target cases. Several implications of these results for decision making under risk are mentioned.  相似文献

The purpose of this paper is to clarify the motives behind business combination decisions. Twenty-one favorable characteristics associated with the motivations for business combinations were selected to serve as the basis for an empirical survey. Our analysis revealed that there are seven motivational variables of varying import and that the motivations underlying business combination decisions are similar for U.S. and Canadian executives.  相似文献
