The present analysis uses data from 1974 and 1981 U. S. cross sections, which incorporate a panel, to compare the standard NES measure of party identification (ID) with a measure of partisanship derived from a party closeness question widely employed in cross-national research. Important features of the two scales are examined by transforming the closeness measure into a scale of very close, fairly close, not very close, and no preference corresponding to the seven-point ID scale. The scales are highly correlated and are similar in their reliability. More than 75% of the independents in the ID scale choose a party in the closeness version, and over half of these select the fairly close category. Respondents do not volunteer that they are independents when that alternative is not stated in the question. 相似文献

This article attempts to estimate the potential impact on birth rates of relaxing various legal restrictions on the marketing of contraceptives and to identify countries offering particular potential for such policies. The approach is through a quasi-experimental cross-sectional analysis of various configurations of laws in 82 countries. Results indicate that relaxation of a complex of interrelated restrictions offers the potential to lower birth rates and hence population growth by a full percentage point. The estimates are made in context of an analysis of covariance in which other key determinants of birth rates (measures of economic, demographic and health status) are also considered. While the cross-sectional design does not allow assessment of time frame for the impact of such changes, some guidance is available from the experience of two countries. 相似文献

A method, adopted from the labor econometrics literature, is proposed for detecting discrimination in punishment. The method requires the separate estimation of time served and punishment probability equations for, say, whites and blacks. The coefficients from the white equation are used to predict the punishment blacks would receive if treated like whites. A test of no discrimination against blacks is a test that the black punishment predicted by the black equation is equal to the punishment predicted by the equation using the white coefficients but the black endowments or characteristics. A further test is proposed that evaluates the economic efficiency of disparities in punishment. The test is restricted to measuring the recidivism effect of equality of treatment in punishment. The discrimination test and the efficiency test are illustrated using the U.S. Board of Parole data for 1972. Statistically significant racial disparities in punishment are uncovered and are found to be economically inefficient. 相似文献

Medicaid waivers play an important role in the health policy process. Various health care policy initiatives have encouraged states to experiment ith their Medicaid programs by expanding coverage to populations not traditionally covered by Medicaid, or by delivering Medicaid services in non traditional ways. Lessons learned by individual states' Medicaid waivers could be an important part of the health care reform debate. This paper presents an evaluation of a Medicaid waiver operating in South I Carolina. The South Carolina Community Long-term Care Waiver for the Elderly and Disabled is evaluated for cost effectiveness, quality of care, and client satisfaction. This evaluation shows that the waiver is highly effective in offering individuals who are medically and financially eligible for Medicaid supported nursing home care a viable, cost effective, high quality alternate to institutionalization. 相似文献

Human morality is a key evolutionary adaptation on which human social behavior has been based since the Pleistocene era. Ethical behavior is constitutive of human nature, we argue, and human morality is as important an adaptation as human cognition and speech. Ethical behavior, we assert, need not be a means toward personal gain. Because of our nature as moral beings, humans take pleasure in acting ethically and are pained when acting unethically. From an evolutionary viewpoint, we argue that ethical behavior was fitness-enhancing in the years marking the emergence of Homo sapiens because human groups with many altruists fared better than groups of selfish individuals, and the fitness losses sustained by altruists were more than compensated by the superior performance of the groups in which they congregated. 相似文献
