College newspapers are a powerful but underutilized medium for educating students on health issues, including those related to drug and alcohol use on campus. Editors of these publications are in a position to wield significant influence among their readers. In addition to communicating factual information about the prevalence and impact of substance use among college students, editors can use the press to advocate changes in students' attitudes and behaviors and in college or community policies that affect substance use. A pilot conference was held to help New England college newspaper editors perceive the importance of their role in educating their peers about substance use and other health-related issues, and to offer concrete suggestions as to how they can incorporate these topics into an "activist" campus press.  相似文献

"The number of forced migrants...is estimated today to exceed 40 million [worldwide]. The changed international climate of the 1990s...has shifted the focus from the asylum and resettlement countries to the countries of origin: there is today a greater willingness to intervene in other countries' affairs either to avert the creation of new flows of focused migrants or to assist internally displaced populations, and there is the expectation of large-scale voluntary returns of refugees in asylum. This article discusses these and other policy issues concerning forced migration in this new international environment."  相似文献

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

"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 authors examine the present conditions of 26 small, isolated populations living in the north of Russia. The total size of the population under consideration is 181,600, according to the 1989 Soviet census. The conclusion is that these populations are under severe threat of extinction and that there is no consensus about how to resolve their present predicament.  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

The aim of this paper is to describe several methods for quantifying the amount of uncertainty inherent in population forecasts used to assess the impact of demographic processes on social security systems. Each method is briefly outlined, and its advantages and disadvantages are discussed. The primary emphasis is on stochastic population models, and the geographic focus is on the Federal Republic of Germany.  相似文献
