The authors construct a theoretical framework for analyzing factors influencing international refugee movements. "On the basis of detailed case studies by the authors of the principal refugee flows generated in Asia, Africa, and Latin America from approximately 1960 to the present, it was found that international factors often intrude both directly and indirectly on the major types of social conflict that trigger refugee flows, and tend to exacerbate their effects. Refugees are also produced by conflicts that are manifestly international, but which are themselves often related to internal social conflict among the antagonists." 相似文献

Two questions concerning the location of a single facility by a voting process are investigated for transportation networks: - What is the maximum number of customers located on the network preferring some rival point over a voting solution? - How does the average distance of the customers to the facility increase when a voting location instead of a Weber location is chosen for the facility? Complete answers are given for general networks and for certain planar networks, viz., the so-called generalized cacti. 相似文献

Abstract Both politicians and voters were asked to predict outcomesof two Oregon ballot measures in 1982. As expected, politicians'predictions always were closer to the mark than voters' were.Further, voters showed stronger signs of wishful thinking (the"Looking-Glass effect") in their predictions than did politicians.Using published preelection polls apparently improved politicians'accuracy in 1982, as well as voters' accuracy in a separate1984 survey. No other sources of data improved predictive accuracy.Findings have implications for theories of representative governmentand are consistent with a new theory of public opinion. 相似文献

This paper demonstrates the need for a broad array of clinical services in treating the emotionally disturbed, mildly retarded youngster in the foster care system. A hypothesis suggests that cognitive deficits and borderline pathology are interrelated, and that treatment involves modifications of traditional therapeutic techniques. The definition of clinical is expanded to include seemingly concrete and environmental services, in addition to the office therapy session. Finally, some systemic impediments to effective treatment of the population are explored.This paper was completed as a requirement of the Post-Master's Program in Advanced Clinical Social Work of Hunter College School of Social Work. 相似文献

This article describes the therapeutic use of canines in child welfare work. The chronically rejected child, or those who virtually spend their entire youth in care, tend to develop a withdrawn, depressed, and suspicious posture toward their relations with other people. This ultimately results in their failure to respond to conventional treatment modalities. Under these circumstances, the canine intervention may prove to be a valuable adjunct, helping to develop and to expedite the process of the therapeutic alliance.This article is a revised version of one presented to meet the requirements for the Masters in Social Work Degree from Hunter College School of Social Work. 相似文献

This paper examines the structure of the present system of immigration control in Australia in the context of its origin, evolution, and responses to current human rights and anti-discrimination standards. The system has serious shortcomings because it confers broad discredionary powers on immigration officals and provides no comprehensive system of judical review. Since the 1970s the system has been gradually losing its legitimacy and has become a subject of challenges by various groups; its efficiency has been undermined and it breeds social conflict and systematic human rights violations. The 1958 Migration Act contains a level of discretion unknown in other "machinery" legislation, conferring a wide range of discretionay power on 1) the minister, 2) authorized officers, 3) officers, and 4) prescribed authorities. The current review system, in response to political pressure and in the context of administrative law reforms, provides for limited access to judicial review under the Administrative Decisions Act of 1977. The ethnic gains of the 1970s were achieved when Australian society was going through a period of profound liberal changes. The 1980s have brought continuing high unemployment and high inflation rates, a large budget deficit and associated restraints in government expenditure, as well as a substantial cut in the immigrant intake after the Labor Victory of March, 1983. Overall, an entirely new immigration control system should be developed that will aim at providing a better balance between stability, predictability, and fairness of the system on the one hand, and the need for government to maintain its ability to adapt its program to fluctuations in economic and social conditions both within and outside Australia on the other hand. 相似文献

Because of cultural, historical and other social structural factors, men and women with the same chronological age have had quite different career trajectories. This paper examines how the different career-paths of men and women academics create differences in their images of aging, self and work. In-depth interviews (N=47) were conducted with a sample of male and female professors, currently between fifty and sixty years of age. Male respondents nearly uniformly followed continuous, linear careers while the women's careers were, with equal uniformity, discontinuous. Data suggest that this difference in career routes fashions different gender timeclocks, i.e., different experiences of aging. 相似文献

This study is a further analysis of the approach taken by Yew-Kwang Ng to derive the utilitarian criterion. Specific for the model is that individual preferences are finitely sensible. In this framweork an analysis of the consequences on social preferences when different kinds of value premises are imposed is made. It is found that the utilitarian criterion is the unique consequence only for very special choices of the value premise. In addition, uniqueness requires the underlying preferences be cardinal. It is also found that finite sensibility induces approximate cardinalization of preferences.I am grateful to Y.-K. Ng, two anonymous referees and an editor of this journal for helpful and constructive comments on earlier versions of this paper.
