The paper shows that if the class of admissible preference orderings is restricted in a manner appropriate for economic and political models, then Arrow's impossibility theorem for social welfare functions continues to be valid. Specifically if the space of alternatives is R + n , n ≥ 3, where each dimension represents a different public good and if each person's preferences are restricted to be convex, continuous, and strictly monotonic, then no social welfare function exists that satisfies unanimity, independence of irrelevant alternatives, and nondictatorship.  相似文献

Recent literature reflects the increased use of RIA as a qualitative and quantitative tool. This study exemplifies the problems that may arise when this technique is used for quantitation. Caution must be exercised, and a physiological and toxicological understanding of each particular drug is essential to provide credible results. It is evident that the sensitivity and ease of the RIA method for methaqualone makes it invaluable as a screening test, but confirmation and quantitation of this drug must remain with those methods that can quantitate each metabolite.  相似文献

This article examines whether spending decisions in Swiss cantons are interdependent, that is, whether the spending decisions of a canton are influenced by those of other cantons. Theoretically, fiscal policy imitation among cantons can be interpreted as a process of policy and innovation diffusion, as a result of tax competition or as a consequence of federalism as a policy laboratory. The panel analysis presented in this article provides evidence of the existence of budget spillovers among neighbouring cantons. Cantonal governments do not take spending decisions in isolation, but by systematically comparing the fiscal policies in neighbouring cantons.  相似文献

Prior studies have found inconsistent relationships between measures of self-concept and adolescent alcohol use. The current study explored whether the link between various measures of self-concept and alcohol use depends on gender. In addition, earlier work suggested a focus on negative self-esteem (i.e., self-derogation) might be more useful in predicting alcohol use. Students (N = 1459) attending 22 middle and junior high schools in New York City completed surveys that included measures of efficacy, self-derogation, and alcohol use. Participants completed surveys at baseline, 1-year follow-up, and 2-year follow-up. Data collectors administered the questionnaire following a standardized protocol during a regular 40-min-class period. On the basis of a longitudinal structural equation model, lower efficacy was related to greater self-derogation a year later across gender. Increased self-derogation predicted higher alcohol use for girls but not boys. These findings are congruent with a literature highlighting the importance of negative thoughts about the self in drinking behavior for women but not men. The results suggest that the alcohol prevention approaches should include material to enhance girls' self-esteem.  相似文献

This study examined the nature and correlates of different patterns of perceived control in adolescents' relationships with their best friends. Participants included firstborn adolescents (M = 14.94 years), their younger siblings (M = 12.44 years) and both their mothers and fathers in 163 families as well as a best friend of each adolescent (M = 15 years). Data were collected from family members during home visits regarding adolescents' family relationships, friendships, and psychosocial adjustment; time use data were gathered during a series of 7 nightly phone interviews. Information was obtained from best friends during a brief phone interview. We developed a typology of 3 different patterns of perceived friendship control based on the combination of adolescents' and their best friends' ratings of relational control. Patterns of control in adolescents' friendships were associated with the distribution of control in both parents' marriages and adolescents' sibling relationships. Further analyses, designed to test developmental predictions, revealed connections between friendship control and other qualities of adolescents' friendships (i.e., intimacy, conflict, perspective-taking).  相似文献
