A comparison of the Korean minorities in China and Japan 总被引:1,自引:0,他引:1
Min PG 《The International migration review》1992,26(1):4-21
"This article compares the Korean minorities in China and Japan in their differential levels of cultural autonomy and ethnic identity....In explaining the differential levels of ethnicity between the two Korean minority groups, this paper focuses on the basic differences in minority policy between the two countries; the difference in the context of migration; the existence or absence of a territorial base; and the differential levels of influence from Korea." 相似文献

Shifts in the American political landscape during the 1980s had impacts on aging policy and on the behavior of aging interest groups through that decade. But perhaps even more important are the likely effects of those changes on aging policy and on the roles of age-related groups in the 1990s--and probably beyond. First, some of the major policy trends of the 1980s are sketched out, especially the renewed emphasis on federalism. Then, an assessment of their effects on aging policy and aging interest groups is provided. Next, a rationale for focusing on state-level policy and a discussion of current aging interest-group mobilization at the state level are presented. Last, the prospects for aging interest-group influence in the 1990s--a period in which the prior decade's emphasis on dual federalism is likely to continue--is addressed. 相似文献

Liu P 《Physician executive》1992,18(5):30-34
As hospital operations become increasingly complex, so does the institution's management and organizational structure. Physician executives with titles of medical director, vice president for medical affairs, medical administrator, chief of staff, medical staff president, etc., are playing more important roles than ever before. This article will briefly review some recent literature describing physician executive profiles. The results from a survey of ten university teaching hospitals are also presented as supplementary information regarding current staffing models. Finally, several physician executive staffing-related issues will be discussed in light of the literature and the survey results. 相似文献

Employers are more readily realizing that a nonsmoking policy in the workplace is a more effective way to run their businesses. They are recognizing costs such as productivity losses, increased health and life insurance costs, employer liability for diseases jointly linked to smoking and occupational exposures, absenteeism, passive smoking-induced health care costs among nonsmokers, workers' compensation, and fire losses. Concomitantly, employees are supporting policies that limit smoking to achieve a clean air environment. Former Surgeon General Koop's goal of "a smokefree society by the year 2000" is being recognized by more and more segments of society. 相似文献

"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 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
