New Voices in Iceland. Parents and Adult Children: juggling supports and choices in time and space 总被引:1,自引:1,他引:0
D. S. Bjarnason 《Disability & Society》2002,17(3):307-326
This paper deals with parents' perspectives and experiences of bringing up children with a variety of impairments in Iceland, and how they impact the young disabled adults' approach to the status of adulthood. The paper is based on a qualitative study that explored perspectives and experiences of 36 young disabled adults (16-24 years old), their parents, friends and teachers. The purpose of this paper is to share themes related to patterns of parents' reactions and choices when coming to terms with parenting a disabled child, the support they found from their social network and professionals, and their sons or daughters' subsequent views of themselves and their prospects as young adults. The paper includes different perspectives on adulthood and the extent to which the young disabled people expect to reach that status or remain as 'eternal youth' enmeshed in segregated services. Findings show that the type and nature of early support for parents of disabled children is critical for the young adults' approaching adulthood in regular society or expecting to remain in the limbo of 'eternal youth' within segregated settings. Early 'betrayals' may, however, be revisited at each subsequent transition point. Furthermore, parents and their disabled children who struggled for social inclusion could obtain full active membership in society, even against social and physical barriers, and medically defined disability labels. 相似文献

There was a time in this fair land when the railroad did not run When the wild majestic mountains stood alone against the
sun Long before the white man and long before the wheel When the green dark forest was too silent to be real
For they looked into the future and what did they see They saw an iron road running from the sea to the sea Bringing the goods
to a young growing land All up through the seaports and into their hands
From “Canadian Railroad Trilogy” by Gordon Lightfoot

Adolescence is often assumed to be the most important period of life for understanding teen childbearing risk. Developmental perspectives challenge that assumption, offering the possibility that early childhood characteristics may have unique and lasting effects on the risk for teen childbearing. This study examined family life risk factors (socioeconomic status, family stress, and parental involvement in education) and how their effects on teen childbearing risk varied, depending on the childhood age at which they were experienced. Prospective life history data from the National Child Development Study of Great Britain were used to study a birth cohort of 4,928 British women, 15.3% of who became pregnant as teens. This study demonstrated that data from early childhood significantly contribute to the understanding of teen childbearing risk. 相似文献

A fundamental problem that confronts the European Union today is how it can maintain its commitment to the institution of asylum while checking irregular migration and the abuse of its asylum system. In order to explore a response to this dilemma the paper addresses the following questions: what role can relief and aid policies play in influencing migration patterns? What should be the appropriate approach to the granting of relief and aid to developing countries of first asylum? Should it be viewed as a part of the larger problem of development or be treated as a distinct issue? What kind of a relief/aid model will help refugees return to post–conflict societies and stop the conflict from reproducing itself? The paper examines two different approaches to address these questions: the alliance–containment approach and the distributive–developmental approach. It also looks at some empirical evidence, which reveals that at present it is a conservative alliance–containment approach that informs EU relief and aid practices. This approach, however, does not help achieve the stated objective of checking abuse of asylum and migration procedures while sustaining a commitment to a liberal asylum regime. The paper goes on to identify the gaps in EU policy and the lessons that can be drawn. It concludes by looking at different policy alternatives and suggesting the adoption of a reformist distributive–developmental model. The implementation of this model holds out the hope of reverting to a more liberal asylum regime while controlling irregular migration and “bogus” asylum seekers, for the reformist distributive developmental model takes a more long–term view of migration trends and also seeks to address the growing North–South divide. 相似文献

We analyze the wealth ejfects of the Texaco racial discrimination lawsuit both on the shareholders of Texaco and its major
U.S. competitors. Employing a comprehensive data set which included every case docket entry and every Wall Street Journal
article on the case as an experimental stimulus, our findings suggest that the overall cost of the case to Texaco shareholders
exceeded $500 million, that Texaco's tribulations had little, if any, impact on the share prices of its major competitors,
and that Wall Street Journal coverage of the case was highly correlated with significant changes in Texaco stock prices. This
last finding provides significant support for Hite 's suppostion that newspaper editors “key ” on ex post stock price changes
in selecting the events to be covered in the next day's edition.

Many methods for obtaining graphical representations of multivariate data have been suggested over the last decade, but it is only relatively recently that software has become available which makes use of these procedures routine. In this paper, a number of examples are used to illustrate the application of graphical methods for the exploration of multivariate data. The diagrams produced may prove useful in consultations with clients and in examining the results from more formal methods. 相似文献
