The refugee situation after the 1984 movement from Indonesia is examined in terms of policy implications and assistance as well as the welfare and education of refugees. Information was collected from government sources and documents and from households in camps and communities over a 3-month period and was published in a government report in February, 1988. This article provides a review of the border issues, resistance and exodus, reactions within Papua New Guinea, 1984-85 border crossings, social and demographic refugee profiles, government response, UN involvement, border refugee camp conditions, repatriation and relocation, reasons for the exodus, and relocation to and conditions in East Awin and the implications. This exodus from West Papua New Guinea (a region now called Irian Jaya) after Indonesia's take over in 1962 represents a unique situation, which also has lessons for other asylum seekers looking for refuge status in friendly neighboring countries. International agreements, such as the Geneva Convention and Protocol, can disrupt social networks and households when the relocation they permit is implemented. Full economic and social participation is hampered by a low quality provision of education and social services. The gain is in removing "destabilizing threats to the host state and society," at the expense of the economic and residential security of the migrants. Humanitarianism hides inequalities; internationalism, in this case, confirmed Indonesian sovereignty and large scale economic exploitation. An estimated 300,000 Melanesians have died since the take over, which amounts to 30% of the total population in 1970. Persecution was the reason for migration to Papua New Guinea; migration numbers are not accurate and range from the official 2000-3000 to 12,000 in 1984. Reactions to the migration have been mixed, and fear of the military might of Indonesia is real. The government was not prepared to cope with the scale of migration and had no plans for food relief, shelter, or medical assistance; the consequence for the refugees was death by starvation. Refugee camps were located along the border; the populations varied by camp. Some were 56% male or female, and 43% of the entire population were 15 years of age. 75% were dependent on subsistence crop production before leaving. Development assistance was dependent on refugee movement away from border areas, in this case to East Awin.  相似文献

The authors describe a project, begun in 1981, to locate, list, and annotate all the published work based substantially on the census enumerators' books for nineteenth-century censuses for England and Wales. The results are currently available in a computerized file, enabling a variety of searches by topic, geographical area, and type of population. Information is provided on using the data and the computerized bibliography. The authors note that, subsequently, data for censuses of Scotland and Ireland have been added.  相似文献

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

"I describe a course on international demography in this paper. The course enables students to use demographic concepts to understand the demographics of various countries and regions. The course involves an introduction, examination of specific geographic regions, and a concluding overview. I also describe several student projects and review available course materials."  相似文献

Computers have become commonplace in nearly every setting, from home to office. In addition to their usefulness for managerial tasks, they have the potential to aid the primary decision-making tasks of professional social service workers. The benefits and background of such "expert systems" are explored, and the structure of one experimental consulting program for child welfare workers, PLACECON, is presented.  相似文献

This article examines the general status in international law of certain fundamental human rights to determine the minimum "no derogation" standards, and then surveys a number of formal agreements between stages governing migration matters, while examining some of the standard-setting work undertaken by the International Labor Organization (ILO) and other institutions. Article 13 of the Universal Declaration of Human Rights, proclaims the right of everyone to leave any country, including his or her own. The anti-discrimination provision is widely drawn and includes national or social origin, birth, or other status. Non-discrimination is frequently the core issue in migration matters; it offers the basis for a principles approach to questions involving non-nationals and their methodological analysis, as well as a standard for the progressive elaboration of institutions and practices. As a general rule, ILO conventions give particular importance to the principle of choice of methods by states for the implementation of standards, as well as to the principle of progressive implementation. Non-discrimination implies equality of opportunity in the work field, inremuneration, job opportunity, trade union rights and benefits, social security, taxation, medical treatment, and accommodation; basic legal guarantees are also matters of concern to migrant workers, including termination of employment, non-renewal of work permits, and expulsion. The generality of human rights is due not because the individual is or is not a member of a partucular group, and claims to such rights are not determinable according to membership, but according to the character of the right in question. The individualized aspect of fundamental human rights requires a case-by-case consideration of claims, and the recognition that to all persons now certain special duties are owed.  相似文献

Throughout the 20th century, the US has feared that political instability in the Caribbean area could be exploited by adversaries; therefore, the US and the nations of the Caribbean share a compelling interest in the region's development. The dramatic increase in legal and illegal immigration to the US from the Caribbean in the last 2 decades has offered an additional human reason for US interest in the region. This migration has also created a new source of dependence and vulnerability for the region. Curtailment of migration would undoubtedly affect the region, and if the effect were social and political instability, then the US would also share those consequences. The 1984 Conference on Migration and Development in the Caribbean held discussions to 1) enhance the benefits of migration to Caribbean development, 2) identify development strategies, policies, and projects that would reduce pressures that have accelerated the rate of international migration, making it less manageable and more costly, and 3) identify ways to reduce dependence on migration by expanding employment and assisting economies in the region to become more self-reliant. The attitudes of both US and Caribbean participants seemed to reflect a considerable degree of ambivalence on the migration issue. The US views itself as "a nation of immigrants" and yet is troubled by the recent large influx of immigrants, particularly illegal migrants and refugees. While Americans recognize that the "brain" reduces the development capacity of developing countries, the US still needs and benefits from young immigrants trained in the sciences, engineering, and computers. Caribbean participants were also ambivalent about immigration. They consider immigration "a way of life" and a "right," but they also recognize that there are significant developmental costs to some types of migration. While many want the US to keep a wide open door to Caribbean immigrants, they are aware that most Caribbean Community (CARICOM) governments are currently closing the door to immigrants even from other CARICOM countries.  相似文献

Blue Shield plans often are granted regulatory advantages by the states in which they operate. Run efficiently, such not-for-profit firms should use these lower costs to eliminate their less advantaged rivals, the commercial insurers. However, these higher-cost commercial providers have been able to offer insurance coverage at prices competitive with the Blues, as evidenced by the fact that Blue plans have, on average, less than 50 percent market share. Similar prices with lower overall costs implies that economic rents are being earned, rents which a not-for-profit firm cannot distribute to owners. In this paper we argue that when there are competing goals among the groups controlling the Blue Shield plans, the different possible "uses" of the regulatory advantage become endogenously determined, necessitating the use of simultaneous equation estimation. Testing this model we find the major effect of doctor-control of Blue Shield plans is to raise doctors' fees while lowering the amount of rents captured by both consumers and administrators.  相似文献

USING DUAL FRAME DESIGNS TO REDUCE NONRESPONSE IN TELEPHONE SURVEYS   总被引:1,自引:0,他引:1  
This article reports on the results of a series of experimentsdesigned to improve response rates for telephone surveys. Inthree surveys telephone households were selected using bothstandard random digit dialing (RDD) techniques and lists oftelephone numbers purchased from a commercial firm. In the RDDportions of the samples "cold contact" interviewing methodswere used; in the list frame portions advance letters were mailed,and the listed household name was used in the introduction.Experiments were designed to test the effects on response ratesof the advance letters and use of the listed household nameas a means of establishing rapport. The advance letters increasedresponse rates, but no difference could be attributed to theuse of names. The mixture of RDD and list sampling techniquesis also used to evaluate the effects of relative response rateson substantive findings. The cost consequences of these dualframe designs are assessed along a number of dimensions, andthe cost and error components of these designs are discussed.  相似文献
