In the context of the academic interest shown in the enduring transnationalism of contemporary migrants and in the modes of transitions to adulthood in different global settings, in this article we examine the transnational lives of adolescents moving between Vancouver (Canada) and Hong Kong. While there is a lot of literature on the parents' political and economic calculations, there is very little on how adolescents in these situations articulate their geographical sensibilities. We draw on three periods of fieldwork undertaken in 2002, 2008 and 2010 during which we employed a transnational methodology to interview young people in Vancouver and Hong Kong. We argue that becoming an adult involves a process in which, in their discussions about the geographical and emotional distance between themselves and their families, young people articulate their own complex emotions towards specific places in their transnational social field. Their families sporadically interrupt the adolescents' otherwise independent lives with fragmented modes of supervision. By examining the complex intentions and emotions behind circular migration from the perspective of transnational youth in a community of split families, we advance the discussion on transnational geographies, particularly of the family in the context of a flexible global economy.  相似文献

Abstract

The authors describe a collaborative partnership forged between faculty and student affairs staff to improve student health at a large urban university. They examine skills and reward structures of each constituency and the stages of the collaboration in the context of 2 theoretical models. A comprehensive data collection and dissemination process in the campus community provided goals for the initial stage of the partnership, leading to implementation of campus initiatives that use the reciprocal skills of each stakeholder. Outcomes of the collaboration included (1) a working relationship between faculty and student affairs staff, (2) increased dialogue with high-level administrators, (3) more coordinated campus efforts to decrease high-risk drinking, (4) use of outcome measures for implementing and evaluating health programs, and (5) an opportunity for interdisciplinary research. The authors offer suggestions for implementing the process on other campuses.  相似文献

Despite increasing numbers of children diagnosed with mental health disorders, there is limited research on how children come to understand these diagnoses in childhood. This study examines the retrospective accounts of emerging adults who were diagnosed with mental health disorders in childhood to better understand how they made sense of their diagnoses over time. In-depth, semi-structured interviews were conducted with 42 emerging adults (ages 18 to 22) who were diagnosed with attention deficit hyperactivity disorder (ADHD), depression, generalized anxiety disorder (GAD), and/or bipolar disorder in childhood. Interviews elicited participants' experiences learning about their diagnoses and suggestions for how diagnoses should best be explained to children. Findings demonstrate that participants actively sought and obtained information about their diagnoses over time. They negotiated narratives from several sources, including parents, teachers, mental health professionals, peers, siblings, the media, reading materials, and the Internet. Many of those who embraced medical accounts of their diagnoses did so as they obtained in-depth medical information over time. Meanwhile, those whose parents were open and communicative without using medical narratives suggest it is possible to share information with children without utilizing the terminology of “disorder.” Participants emphasize the importance of being open with children and providing them assurances, explaining that their problems are legitimate, common, and “not their fault.” Implications for social work practice are discussed.  相似文献

Doctoral education is greatly impacted by context, and the large majority of marital and family therapy (MFT) doctoral programs are PhD programs in research-focused universities. I believe their primary mission is to equip students to become scientist–practitioners and do original research that will advance the science of the discipline, whereas the mission of the typical master’s program is to produce strong practitioners who are research informed. It is the emphasis on the scientific method, not the content specialty area, that should be the hallmark of PhD programs in research-focused contexts. I describe metrics for success that include not only research productivity but also the development of a supportive, open, flexible, and generous program culture. The research mission of these programs has been only modestly helped by the Commission on Accreditation for Marriage and Family Therapy Education process and the programs are largely not doing the programmatic intervention research that the field needs. As the universities that house these programs are also “raising the bar,” the long-term viability of the programs themselves will likely hinge on success in this arena.  相似文献

The objective of the paper is to apply the statistical procedure of ridge regression to a multivariate model of criminal activity. The explanatory variables are of an economic, apprehension, and seasonal nature. The Time Shared Reactive On Line Laboratory (TROLL) computer package was used in estimating all regression coefficients and other pertinent statistics. The economic variables, which included per capita personal income, hours worked, and plant closing dummy variable, were found to be statistically related to criminal activity. In addition, police expenditures as well as the three seasonal dummy variables were statistically associated with the dependent variable. A comparison is made between the results obtained from the ordinary least squares procedure and the ridge regression approach.  相似文献

Australian Marriage Guidance Councils are rarely considered avant garde. Yet contemporary emphasis on the importance of citizen participation in social service delivery programmes1 unexpectedly shows them in the vanguard of the new art of mobilizing participatory community services. For more than a quarter of a century now they have been operating as expert guides and counsellors in the difficult territory of marital therapy, mainly using staffs of part-time counsellors drawn from the general community. The magnitude of this feat of maintaining the participatory character of this community service in a potentially rich field for professional exploitation goes largely unacknowledged. It has been pointed out that the professional, “because of his status, commitment and knowledge”,2 is in most cases successful in converting citizen participation programmes into the service of his own professional interest. This has always been one of the most intractable problems of any participatory scheme. So far the Marriage Guidance Councils have stayed right on top of this problem.  相似文献

An inverse regression approach to analyzing quantal response assays with one quanritative independent- variable and any number of qualitative independent variables is presented. A general factorial model ror LQC- inverted relationship and methods of testing hypotheses estimating qulitative Interest are developed. This naper provides a modified method of analysis which is easier to apply than previously existing methods.  相似文献
