This paper extends earlier research into methods for estimating adult mortality from information on the recent incidence of orphanhood. It presents a series of regression coefficients for estimating female and male mortality from synthetic cohort data on the subsequent orphanhood of those who had a living mother or father at exact age 20. Such information can be obtained either where questions about parental survival have been asked in two inquiries or by asking retrospectively about dates of orphanhood in a single survey. Although the method is somewhat sensitive to errors in the reporting of ages and dates, it is a promising source of up-to-date estimates of adult mortality that are free from bias due to the underreporting of the orphanhood of young children ("the adoption effect"). 相似文献

"The author...has attempted to measure the effects of population changes upon the costs of health care [in Poland] by applying a simulation model. In this model the total cost of health care is a function of the per capita cost of health care by age, sex, and place of residence (urban, rural) and population structure.... The paper includes...the results concerning population 60 years of age and over." Data are from several official health-related surveys carried out in 1989. 相似文献

Davies A 《Long Range Planning》1991,24(2):94-100
Although the planning operation is regarded by some observers as unrealistic in conditions of rapid change and increasing competition, the discipline of strategic thinking and the need for strategic leadership continue to be of vital importance. The author examines the purpose of the Board of Directors and its role in the management of strategy. 相似文献

Polls do not simply measure public opinion; they also providevital information that the public can use to form opinions andto make decisions. Using multiple regression analysis, the authorsfound that published polls had a powerful impact on the valueof the Canadian dollar during the 1988 Canadian federal election.This appears to have been due to the unprecedented importanceof economic issues in the federal campaign, the distinctivepositions taken by the major political parties with respectto the U.S.-Canadian Free Trade Agreement, and to the proliferationof "horse-race" polls in the media. These results have implicationsfor understanding the behavior of other elite groups, such asfinancial contributors and volunteer campaign workers, who mayalso use published horse-race polls to handicap election outcomes. 相似文献

RACE-OF-INTERVIEWER EFFECTS IN A PREELECTION POLL VIRGINIA 1989 总被引:1,自引:0,他引:1
All published preelection surveys of the 1989 Virginia gubernatorialcontest overestimated the vote share of the black candidateand eventual victor, Douglas Wilder. We offer a "social desirability"interpretation of the polls' inaccuracies and hypothesize thatclaiming support for Wilder was the socially desirable responsefor some whites, especially when the interviewer was black.We show a race-of-interviewer effect on the vote intention ofwhite respondents of 8–11 percentage points in a preelectionsurvey of Virginia voters. The effects were greatest among whiteDemocrats and among whites who were more uncertain of theirvote intention. We discuss the implications of these findingsfor race-of-interviewer research and for improving the accuracyof preelection forecasts in contests with black and white opposingcandidates. 相似文献

Recent trends in the process of stratification 总被引:1,自引:0,他引:1
Using the 14 annual cross-sections from the General Social Survey, we specify a "basic model" of attainment and describe the year-by-year fluctuations in its parameters. The results are partially consistent with theories describing the gradual growth of universalistic patterns of stratification and mobility. Under a linear model of educational achievement, we find that the direct effects of race are weakening and the returns to class-based advantages are declining in tandem. The contours of the socioeconomic "gender gap" are also changing in important ways, with the male intercept declining at a rapid pace and the female term registering small and insignificant year-by-year gains. At the same time, the returns to experience and schooling are increasing for men, whereas the corresponding returns for women have remained stable over the 15-year period. This pattern of interaction effects implies that the size of the gender gap varies over time and across different population groups. 相似文献

In this paper we attempt to explain the occurrence of population cycles in industrialised economies where the birth rate depends on the difference between the actual and the expected consumption rate. This model of an endogenously growing population brings together Easterlin's idea of an adapting aspiration level with the neoclassical optimal growth paradigm. It is shown that in this highly aggregated demo-economic system (i.e., without inclusion of the age structure of a population) swings both in the economic and demographic variables may exist. The reason behind this strange optimal behaviour is identified to be an intertemporal substitution effect between current and future levels of consumption.We wish to thank A. Novak for helpful assistance and an anonymous referee for useful comments. Financial support by the Austrian Science Foundation under contract No. P6601 is acknowledged. 相似文献
