A projective (2n,n,λ,1)-design is a set of n element subsets (called blocks) of a 2n-element set V having the properties that each element of V is a member of λ blocks and every two blocks have a non-empty intersection. This paper establishes existence and non-existence results for various projective (2n,n,λ,1)-designs and their subdesigns. 相似文献

This paper examines the theoretical and empirical basis for common rank-orderings of occupational roles by raters throughout the world. From an illustrative comparison of occupational stratification in Australia and the United States we conclude tentatively that (1) commonalities in the socioeconomic characteristics of occupational roles provide the basis for interplace consistencies in “prestige” scores, (2) the structure of occupational mobility in the U.S. and Australia is largely similar, (3) this similar structure of occupational stratification manifests a common socioeconomic process which defines a (the?) major component of occupational mobility in capitalist, industrial (only?) societies. We infer that “prestige” scores for occupations are fallible estimates of the socioeconomic statuses of occupation, within the context of mobility processes in (at least) the U.S. and Australia. 相似文献

Recent meta-analyses and experimental designs of batterer program evaluations suggest little or no program effect. This finding may be compromised by a variety of analytical issues. Instrumental variable analysis addresses some of these issues, especially the relationship of program dropout to batterer reassault. This method of analysis was, therefore, used to test for program effect in a multi-site evaluation. The sites were three well-established batterer programs using a gender-based, cognitive-behavioral approach (n = 640). Completing a batterer program reduced the likelihood of reassault by 44% to 64%, depending on the specification used. Completing a 3-month program appeared to be as effective as completing a 5 1/2- or 9-month program. This moderate effect is an accomplishment considering the problems associated with the program participants and the inconsistency in the criminal justice system at the research sites. The findings remain tentative because of weak instrumental variables for reassault, but do confirm the need for more complex analyses of program effect. 相似文献

The aim of this work is to be a useful instrument for helping finance practitioners on the selection of suitable mutual fund portfolios. The portfolio selection problem is characterized by imprecision and/or vagueness inherent in the required data and more generally, in the context where investors have to make decisions. In order to mitigate these problems, a three stage model has been proposed based on a multi-index model and considering several market scenarios described in an imprecise way by an expert. The proposed fuzzy model allows the Decision Maker to select, by means of an outranking method, a suitable portfolio taking into account the uncertainty related to the market scenarios and the imprecision and/or vagueness associated with the model data. 相似文献

The aim of the article is to show how the extent of democracy in two Eastern European societies has a strong conditioning effect on the development of social movements. Hungary and Russia are chosen as contrasting cases. The experience of environmental movements before and after the regime change is used as an illustration of grassroots movements. It is shown that environmental movements in Hungary are more numerous and more successful than those in Russia, and that this is linked to the extent of support they have (or lack) from politicians, non-elected officials, and the media.
In Hungary, although ecological issues are not central, politicians and environmental groups mostly co-operate, whereas in Russia the relationship is either hesitant or sometimes even hostile. In both countries, however, apparatchiks are generally a lot more opposed to grassroots groups, such as environmental ones, but their weaker position in Hungary compared with Russia cancels out this effect. Finally, the media in Hungary have been sympathetic to environmental issues and they are also supportive of the environmental movements. In contrast, however, in Russia, after Yeltsin's arrival in power 'glasnost' has been largely reversed and the media have also been hostile to environmental groups. In sum, the position of the media, politicians and officials shapes the prospects for environmental movements and is an index of the differing degree of democracy in the two societies. 相似文献
