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

Much of the strategic preoccupation of senior managers in the 1990s is focusing on the creation of customer value. Companies are seeking competitive advantage by streamlining the three processes through which they interact with their customers: product creation, order handling and service assurance. 'Micro-strategy' is a term which has been coined for the trade-offs and decisions on where and how to streamline these three processes. The article discusses micro-strategies applied by successful companies.  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
