This paper deals with the destination decision of political migrants who, in spite of having strong cultural, ideological and religious ties to a particular potential destination, choose to emigrate elsewhere. The model presented characterizes the migrants, who have a choice of two possible destinations, by two properties, skill level and financial resources, and identifies those that move to each destination. The paper examines various immigration-encouraging policies and shows that although all of them will increase immigration, in some cases the economic quality of the new immigrants will rise and in some it will fall. This paper includes general evidence on the present immigration to Israel and some suggestions for empirical tests.Supported by the Schnitzer Foundation for Research on the Israeli Society and Economy.We would like to thank two anonymous referees for their valuable comments which simplified the presentation.  相似文献

Social workers are required to collect a considerable amount of personal information about clients and their families which may be unrelated to direct clinical work. Administrators often use this for the purpose of payment, service documentation, agency planning, and accountability. The worker's concern about the appropriateness of collecting this data may result in poor compliance or even falsification of information. In a survey of Minnesota social workers, noncompliance with data collection requirements was substantial. The authors also found a significant degree of conflict about privacy and confidentiality issues. These findings suggest a basis of concern for those who must rely on accurate data for administrative planning.  相似文献

"This article shows that an analysis of the impacts of immigration [in Western Europe] has to be divided into allocational and distributional aspects. From an allocational point of view, like free trade in goods, services and capital, migration is welfare-improving as long as marginal productivities of labor are not equalized worldwide. From a distributional point of view, however, the immigration society has to bear the effects of sharing its common public goods and its social values with the new immigrants. Free immigration will only be allowed if the allocational welfare gains exceed the distributional welfare losses. According to this rule of thumb, a guideline for an efficient migration policy is sketched."  相似文献

"This article is focused on Turkey and Turkish emigration abroad. It examines integration of second generation immigrants in Western Europe and various forces fostering Islamic identity. It then compares political discourse on immigration in France and Germany. It concludes that the resurgence of ethnic identity as the basis for effective political action in widely divergent societies is a key feature of the post-Cold War period."  相似文献

Demographic trends in rural areas of the former Soviet Union are analyzed over the 10-year period 1979-1989, using census data. Over the whole country, the rural population decreased by 1 percent, while the urban population increased by 15 percent, although significant differences existed between the European and Central Asian republics. Factors affecting the dynamics of rural populations are analyzed, including the undeveloped social and economic infrastructure in rural areas.  相似文献

The application of the subjective variable to research on attitudes toward fertility in Poland is considered. The variable concerns the determination of ideal family size and attitudes toward having more children. The author shows how an ex post facto variable was constructed, describing positive, negative, and neutral feelings toward fertility during the course of a study on attitudes toward procreation.  相似文献

This study examines the possibility that estimation of the effect of breast-feeding on infant survival is affected by selection bias, in that children who are healthier at birth may be more likely to be breast-fed. Data are from the 1976 Malaysian Family Life Survey. "Ordinary logit models for breast-feeding and survival are estimated, and the results suggest that selection is indeed present. For example, children of higher birth weight appear to be more likely to be breast-fed and likely to survive. In addition, weight at birth and the duration of breast-feeding appear to be linked." Using birth weight as an indicator for the child's health, the authors conclude that "the direct influence of breast-feeding on survival remains of overwhelming importance even after corrections for selection bias are made."  相似文献

A fact-gathering, experimental game proved to be an effective instrument in the needs assessment phase of an adolescent sexuality educational program aimed at low-income females. The game ("Family Few"), which covered the topics of menstruation and reproduction, was played by 35 Black, Hispanic, and white females aged 13-16 years recruited from medical and psychiatric clinics in Miami, Florida. The goals of the game were to elicit terminology used by participants, identify and correct misconceptions and misinformation, and determine if learning could occur. Although 57% of participants reported prior exposure to formal sex education, misinformation about the need for activity curtailment during menstruation and the importance of early pregnancy detection was widespread. Group members believed they needed to restrict activities involving physical exercise, sexual relations, water, and cold during menses and were not likely to seek medical or family consultation regarding a missed period until the end of the 1st trimester of pregnancy. Also evident was a need for accurate information on the side effects, risk factors, benefits, and effectiveness of contraceptive methods. The group responses enabled the sex educators to prepare a culturally responsive, developmentally oriented curriculum for further work with disadvantaged female adolescents. The group process was ranked highly on the Likert Scale by these teenagers as an enjoyable, useful means of information dissemination and problem solving.  相似文献
