This paper extends the author's recent work on dynamically consistent consequentialist social norms for an unrestricted domain of decision trees with risk to trees in which the population is a variable consequence — i.e., endogenous. Given a form of ethical liberalism and ethical irrelevance of distant ancestors, classical utilitarianism is implied (provided also that a weak continuity condition is met). The repugnant conclusion that having many poor people may be desirable can be avoided by denying that individuals' interests extend to the circumstances of their birth. But it is better avoided by recognizing that potential parents have legitimate interests concerning the sizes of their families.That action is best, which procures the greatest happiness for the greatest numbers. Francis Hutchison (1725).An abiding interest in concepts of optimality for the choice of population has been stimulated by frequent discussions with Partha Dasgupta. This paper was presented at the seminar on Distributive Justice and Inequality at the Wissenschaftskolleg zu Berlin, May 1986. I am grateful to the audience for their helpful comments, especially Maurice Salles and Patrick Suppes, and especially to John Weymark for carefully reading and suggesting distinct improvements to the earlier version.  相似文献

"The purpose of this paper is to look at what has been achieved by the transmigration program [in Indonesia], to examine the major problems that have arisen and to consider the present constraints which now cast some doubt upon the future of the program." A historical overview of government policies from 1905 to 1988 is provided, and problems of land supply, land use, and lack of funds are discussed. Data are from the 1961 and 1980 Indonesian censuses. (SUMMARY IN FRE AND SPA)  相似文献

Data from the 1973 and 1986 General Social Surveys are usedto test the hypothesis that elderly individuals favor publicspending patterns that support their own interests and not thoseof children. Support for educational spending and welfare bythe elderly is found to be less than within other age groups.Age patterns of support for Social Security spending are mixed.Responses to a series of "vignettes" depicting low-income familieswith young children and elderly women living alone showed thatelderly respondents are slightly more supportive than averageof transfers to low-income families with children and less supportivethan average of transfers to low-income members of their owncohort. Elderly respondents appear more generous once theirmore frugal notions of what it takes to "get along" are takeninto account. Support for transfers to young families is moreclosely related to income than age and is not consistent withthe hypothesis that the elderly support programs that benefitthemselves at the expense of programs that benefit the young.  相似文献

"This study examines the relationship between black population concentration (% black), black population change and white population change for small American suburbs for the 1950-1980 period. Linear, tipping point (curvilinear) and interaction models of racial transition are evaluated for each decade by region (South and non-South), controlling for several other suburban characteristics (age, annexation and distance to the Central Business District) which may affect both black and white population change. The analyses show that racial transition in suburbs involves the parallel development of white and black populations with mainly weak and complex causal linkages which are sensitive to broader suburbanization patterns."  相似文献

BELIEVABILITY AND THE PRESS   总被引:3,自引:0,他引:3  
This study looks at believability ratings assigned to 39 newsorganizations and news personalities by a nationally representativesample of 2,104 adult men and women. The data provide threemajor findings about the believability of the American press,all of which, at least in part, tend to be at odds with muchof the conventional wisdom and some of the contemporary researchdealing with the credibility of the news media. First, the overwhelmingmajority of the general public believes most of what it hears,sees, or reads in the nation's press. Second, perceived "believability"of the news media is not closely related to those politicaland demographic variables that typically divide public opinionin America. Third, the public does "group" the news media interms of "believability," but the groupings do not equate withthe dichotomy usually drawn between television and print journalism.  相似文献

"A mixed model is proposed for the analysis of geographic variability in mortality rates. In addition to demographic parameters and random geographic parameters, the model includes additional random-effects parameters to adjust for extra-Poisson variability. The model uses a gamma-Poisson distribution with a random scale parameter having an inverse gamma prior. An empirical Bayes approach is used to estimate relative risks for geographic regions and annual rates for demographic groups within each region. Lung cancer in Missouri is used to motivate and illustrate the procedure."  相似文献

"Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1900 decennial census."  相似文献

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

1. Several factors may affect an elderly client's use of medications: polypharmacy, potentially leading to interactions; over-the-counter drugs taken without a physician's knowledge; noncompliance or poor compliance with medication regimens; and ageist beliefs. 2. Psychiatric nurses must be aware that the signs and symptoms they observe may be the result of normal physical or biological aging, psychosocial changes, disease-related changes, medication side effects, or a drug interaction. 3. Nurses must ask two questions when psychotropic drugs are used with elderly clients: What will be the onset, duration, magnitude, and characteristic action of a specific drug in an individual; and What are the characteristics of an "ideal" medication?  相似文献

1. It is important to examine client and staff satisfaction with the RN case management (RNCM) model to enhance the quality of care in psychiatric settings. 2. Ninety-two percent of clients surveyed ranked the RNCM care as "excellent" or "above average." Clients valued most the humanistic role of the RNCM and repeatedly commented on the importance of the nurse being caring, genuine, and supportive. 3. RNCMs expressed high satisfaction with their role, which they described as collaborative with the psychiatrist, yet also professional and independent. Psychiatrists expressed a high degree of confidence that clients were receiving excellent care by competent nurse professionals.  相似文献
