We analyse the existence of preferred numbers on the French Lotto market and prove that this market is not strongly efficient in the sense of Thaler & Ziemba (1988). The preference for low numbers is investigated by means of stochastic dominance tests. The specific features of the French Lotto game allow us to build a simple estimate of the probability distribution of numbers actually played. The results are compared with the (highly time-consuming) maximum likelihood estimator used by Farrell et al. (2000). It is shown that the two methods give very close results. Our conclusions stress the perspectives of this study in various domains. 相似文献

Regulations under Section 112(r) of the 1990 Clean Air Act Amendments require fixed facilities having threshold quantities of materials on the U.S. Environmental Protection Agency's list of regulated substances to disclose to the general public the expected offsite consequences of worst-case accidental chemical releases. This paper describes the communication practices of small firms in Delaware and New Jersey and the practical problems these facilities might encounter complying with the proposed rule. The paper reports an interesting difference between the apprehension voiced by small firms required to report worst-case release information and the public's apparent lack of interest in such information. Unlike the difficulty expected by small firms in calculating and communicating worst-case chemical release information, this paper includes some observations on the ability of large chemical firms to comply with the proposed requirements. 相似文献

This paper examines the response of residents in one inner-city, racially, and economically diverse neighborhood to a sudden increase in crime, drugs and disorder. Rather than withdrawing, residents in this neighborhood responded by organizing a major collective effort to develop a stabilization plan for the neighborhood. Factors useful in understanding this atypical response include a citywide structure that encourages citizen participation, the city government's commitment to the neighborhood, a history of neighborhood activism, and residents' commitment to the neighborhood. A social movement perspective that examines the nature of successful social movement organizations, the political context of movement activities, and micromovement processes is useful in analyzing cases of neighborhood activism. 相似文献

This study examines the determinants of compensation for fundraising professionals by addressing the following research questions: (1) Is there a significant pay‐performance relationship? (2) What are the factors that affect bonus and salary? (3) Is there a gender‐pay gap for individuals who are in the role of fundraisers? Data were collected over a four‐year period from a national sample of fundraising professionals employed across all industry classifications. Amount of money raised was the primary performance variable of interest. Bivariate tests for differences between males and females, as well as two‐stage simultaneous regressions, were used to determine the effects of fundraising performance on the pay of fundraisers. Results indicated a significant and positive pay‐performance linkage across all fundraising positions, particularly for chief development officers, as well as a consistent gender‐pay gap across fundraising positions. 相似文献

There have been increasing calls for the United States (U.S.) government’s implementation of broad public access policies mandating free online access to federally funded research. This study examines the potential impact of such a policy on peer-reviewed forestry literature. The authors analyze information about federal government authorship, federal government funding, and U.S. authorship indicated in articles published in five core forestry journals in 2006. The results of the analysis provide evidence that federal public access legislation would have a significant impact on the accessibility of forestry literature published in leading journals in the field. 相似文献

This article reports two studies that investigated the ways in which children use gender and ethnicity for making judgments about food choice. In Study 1, White and Asian 5- to 10-year-olds (M = 7.37) were asked to rate how much they and others would like novel non-stereotyped foods. White children inferred that girls and White others would like the foods more than boys and Asian others would. An 'ethnocentric' pattern was found where children inferred that ethnic in-group others' food-liking would be more similar to their own compared with ethnic out-group others. These patterns were replicated with adults. In Study 2, a larger range of foods was used to assess White, Black, and Asian 3- to 8-year-olds (M = 5.63), followed by gender and ethnic categorization and constancy tasks. Children from five to six years used ethnicity-based reasoning, which was influenced by their ability to categorize themselves and others by ethnicity. The role of social categories in food choice is discussed in the light of theories and research in category-based reasoning. 相似文献
