O'brien P 《The International migration review》1992,26(2):373-387
"This article examines past and present migrations to Germany from the perspective of nation-state formation.... Focusing on the many experiences with the Polish minority (ranging from the eighteenth century to the present), this essay suggests that Germans have never discovered an acceptable and workable approach for dealing with large non-German minorities in the German nation-state. Rather, different regimes at different times have vacillated between an exclusive approach founded on nationalist principles and practices and an inclusive one founded on liberal principles and practices.... The confusion over the two approaches produces not only a confused immigration policy, but also reflects deep-seated confusion over the definition of the new German state and identity of the newly united German nation." 相似文献

The All-China Women's Federation (WF) is a non-governmental organization of women and the highest leading body of the Women's Federations at all levels of the country. The WFS spare no efforts to do women good turns, work for their well-being and serve them wholeheartedly. The WFs are actively organizing women to learn to read and write and to acquire skills. The WFs play a role in protecting and education women, and in struggling for the safeguard of the legitimate rights of women and children. The WFs at all levels have been showing great concern for family planning. Finally, the WFs devote much attention to the training of women cadres, and to the improvement of their cultural level and working ability. 相似文献

"The study investigates the departure from Australia of former settlers who arrived during the 1980 calendar year. The 1980 settler arrival cohort [consists] of 75,167 visaed migrants.... The study has three main aims: (i) to analyse departures from Australia of the 1980 settler arrival cohort with a view to gauging the success of Australia's immigration program in retaining settlers; (ii) to examine the retention rates of settlers with respect to characteristics...including age, sex, marital status, country of last residence, and settler eligibility category; and (iii) to consider implications of the findings." Australia's present immigration policy is discussed, previous research on return migration from Australia is summarized, and a detailed analysis of the departure data is presented. "This study found that by August 1984, 12.4 per cent of non-refugee settlers who arrived in Australia during 1980 had departed permanently but that only 0.6 per cent of the 1980 refugee cohort had done so." These figures represent a decline in immigrant departure rates since the 1960s and early 1970s. Small differences in departure rates by place of birth, age, and marital status, which may have demographic consequences if sustained over time, are noted. (SUMMARY IN FRE AND SPA) 相似文献

"This article highlights important developments in the character of temporary worker flows to Canada between 1973 and 1985 through the use of unpublished data and new measures for analyzing this data. The number of employment authorizations are converted to person years to indicate the overall labor market impact of temporary worker flows and this measure is employed in an analysis of unpublished data from Employment and Immigration Canada. The analysis reveals that a significant and growing proportion of employment authorizations are exempted from governmental procedures which link the admission of temporary workers to the Canadian labor market." Reasons for these exemptions and policy implications are discussed 相似文献

The UN High Commissioner for Refugees (UNHCR) commissioned researchers from the University of Zambia to conduct a socioeconomic survey and census of "spontaneously settled" Zairean and Angolan refugees in the Northwestern Province of Zambia in 1982. The sample consisted of 188 Angolans, 201 Zaireans, and 2 South Africans. The difficulties experienced by refugees in Northwestern Province in achieving integration were related to a combination of factors including the lack of a clear national policy on refugees and refugee status, a national concern for maintaining security, the popular belief that aliens are responsible for an increasing crime rate, the desire by immigration officials for stricter laws to control alien infiltration, conflict between traditional and modern leaders, and Zambia's deteriorating economic situation. In spite of the problems described, the integration of refugees into existing communities is a desirable goal and should be encouraged. One should not assume that self-settling refugees are able to live with ethnic kin, receive assistance and hospitality, and thus are better off than those in camps. The Zambian case provides ample evidence that integration is not easy even with kin support, shared ethnicity, language, and historical connections. Moreover, given the fact that Zambia will continue to receive refugees it is vital that there is a well defined refugee policy and an administrative mechanism for implementing that policy at all levels. This will be particularly important in Zambia as it will undoubtedly continue to receive large influxes of refugees, from countries such as Namibia, Uganda, Angola, Mozambique, and South Africa. 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 article analyzes Canada's employment visa program, through which foreigners enter the Canadian labor market for relatively short time periods. It further demonstrates some major differences between this policy and the European guest worker scheme. Governments in Western Europe viewed guest workers' benefits as preventing wages and inflation from rising, allowing profits and investments to increase, and sustaining economic growth. A question to consider is whether guest workers' demands on social services, in relation to their tax and other contributions, exceed those of the indigenous population and thus reduce their profitability. Canada, in contrast, has avoided the need to provide services for the children of foreign workers or jobs for their spouses by limiting visa length to a maximum of 1 year. The majority of employment visa holders to Canada enter without dependents. Another difference is the far smaller scope of the Canadian program. Canada's employment visa program provides only about 0.5% of total employment, whereas guest workers in European countries may comprise up to 23% (Switzerland). The occupations of service and teaching account for the majority of workers included in the Canadian visa program, while manufacturing subsumes a large share of European guest workers. It is important to stress that, with relatively low levels for permanent immigration to Canada, the employment visa program rivals that flow as a yearly contributor to labor supply, indicating a need for closer attention to the evaluation of this policy. 相似文献

Fifty high school students met in same-sex dyads for the first time over a cup of coffee in an experimental room designed as a comfortable living room. They then responded to a questionnaire designed to measure liking and perceived similarity. The interactions were video-taped. Two different panels of 6 judges later either viewed (video only) or heard (audio-only) the videotape and raed the subjects behavior on a number of scales. The judges also judged the degree of liking felt by the subjects by estimating subjects responses to the questionnaire. In addition gaze behaviour during the interaction was measured. Factor analysis demonstrated that 60% of the variance in The Liking Scale was attributed to 14 items relating to liking and perceived similarity. A separate factor to assess perceived similarity could not be found. Twenty-nine percent of the variance in the liking reported by subjects was predicted by an interrelated pattern of expressing behaviour including approproate looking, mutual gaze, self-disclosure, synchrony in movement and gesture, expressiveness of the face and liveliness of the voice. Video judges liking correlated 0.33 with subjects liking and 48% of the variance in their judgements was explained by the valid cues of looking and expressiveness of the face. Audio judges liking, although it correlated at 0.34 with video judges liking, did not correlate at all with subjects' liking because of an over-reliance on the important content cues. It is suggested that major problems leading to decoding inaccuracy may be over-reliance on content cues and over-confidence in the possibility of decoding accuracy. The evidence suggests that differences between subjects in encoding may be considerable. 相似文献
