The number of Arrovian constitutions, when N agents are to rank n alternatives, is p(n)
p(n)
N
, where p(n) is the number of weak orderings of n alternatives. For n≤15, p(n) is the nearest integer to n!/2(log2)
n
+1, the dominant term of a series derived by contour integration of the generating function. For large n, about n/17 additional terms in the series suffice to compute p(n) exactly.

This article is a continuation of analyses of cursillo. The specific concerns addressed are the development of the appropriate linguistic skills, that is, learning how to “talk the talk “of cursillo, and the development of the appropriate behavioral skills, that is, learning how to “walk the walk” of cursillo. When these skills are developed and used appropriately a form of ranked status mobility within a cursillo center can occur. 相似文献

Globalization has brought about fundamental change. But, the same theory that shows that free trade is beneficial also shows that globalization can be harmful to at least one of the trading countries. Moreover, with globalization, the interests of a country and its companies may diverge. In this paper, we examine free trade in a globalizing world and identify the key policy issues that economists and industrial leaders, alike, must address in today's interdependent world. 相似文献

In a typical carcinogenicity study, animals, usually rats or mice. are divided into a control and two to three dose groups of 50 or more by randomization. A chemical is administered at a constant daily dose rate for a major portion of the lifetime of the test animals, for example, two years. In general, such an experiment is expensive and time consuming In this paper, we propose an efficient design with reduced sample size and/or shortened study duration. An equal number of animals per dose group is considered in this study. A power study of the age-adjusted trend test, for the turnor incidence rate for single-sacrifice experiments proposed by Kodell et al. (Drug Information Journal, 1997) is conducted. A Monte Carlo simulation study is performed to compare the performance of the trend test for the standard design and various reduced designs. Based on the Kodell et al. test, the 21-month study duration with sample size 50 per group is recommended as the best, reduced design over the traditional 2-year study design with the same sample size. 相似文献
