It is shown that when a parameter lying in a sufficiently small interval is to be estimated in a family of uniform distributions,
a two point prior is least favourable under squared error loss. The unique Bayes estimator with respect to this prior is minimax.
The Γ-minimax estimator is derived for sets Γ of priors consisting of all priors that give fixed probabilities to two specified
subintervals of the parameter space if a two point prior is least favourable in Γ. 相似文献

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

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

Although the vast majority of deaths occur among terminally ill geriatric patients, little is known about the etiology of these patients' death acknowledgement and ultimate type of treatment. Based on interviews with 76 triads composed of physicians, terminally ill patients, and primary caregivers, this study uses the socialization perspective to identify the actors and actions that most strongly affect the patient's death acknowledgment and receipt of exclusively palliative care (i.e., socialization to the dying role). Whereas patient preferences and sociodemographic characteristics do not influence significantly the patient's odds of death acknowledgment, these odds are increased if their primary caregivers accept death, their physicians are not affiliated with a teaching hospital, and the terminal prognosis is disclosed to them and disclosed "matter-of-factly." Patients who acknowledge death, whose agents value pain alleviation over life-prolongation, and whose physicians are not affiliated with a teaching hospital, are substantially more likely to receive exclusively palliative rather than curative terminal treatment. 相似文献

A case study of temporary and circular Melanesian population mobility and labor migration focuses on the island of Paama in the Republic of Vanuatu (an archipelago of 80 islands) in Melanesia and on urbanization, which is a relatively recent phenomena. A critical analysis is provided of temporary and permanent migration and methodological inadequacies in explanations of mobility. Mobility is neither a cause nor a result of economic, social, and political change; it is the interrelationship among the general structural setting, people's personal and social environment, and their perceptions and actions. In the case of Paamese mobility, changes appeared in the source of migration and destination areas. There was a period of original land acquisition, when migrants returning from Queensland with tools were the only ones who could actually acquire land. Inequalities of land access date from this period. The population is dependent on external income sources as well as the need for plantation migration and a huge increase in bridewealth. Concurrently, "kampani" or community work, which ensures the continuous authority of local chiefs and village elders, creates problems for those seeking work for their own families. These conditions encourage out-migration. Rapid urban growth began in the 1960s with a diversified economy. Employment opportunities were available for women; single employee residence spaces declined. This meant families could permanently settle in urban areas. Retirement benefits were also available and contributed to securing permanent migration. There were growing needs for a stable, skilled labor force. Another change was the abolishment of the tripartite colonial administration. Rural disasters and price declines also triggered urban migration. Migration to the town of Port Vila by Paamese men and women between 1953 and 1982 is analyzed, based on 258 employment related mobility histories collected in 1982-83. Two processes are evident: continued periodic, short-term, rural-based circulation and permanent urban migration among Paamese to Port Vila. A major reversal of mobility is unlikely in the future. The reasons why are indicated. 相似文献

G Hekma 《Journal of homosexuality》1986,13(2-3):43-55
Various styles of "male love" occurring in the 19th century are introduced. Locations and public ordinances relating to these styles of love are discussed. The development of the homosexual role is broached along with the question of whether attitudes and laws of the 19th century were responsible in part for the development of normative expectations for homosexuality which might in turn have repressed its growth. 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
