Objective. The objective of this article is to examine whether racial tolerance attitudes are influenced by the character of the urban subculture in which individuals live. Specifically, is there a significant association between Florida's (2002) concept of creative class and racial tolerance among white survey respondents? Methods. The Social Capital Community Benchmark Survey that comprises respondents across some 27 cities provides the data for this analysis. Ordered logit regression was utilized. Results. Independent of key explanations of racial tolerance such as racial threat and contact theories, creative class or new political culture cities are associated with more progressive racial attitudes among white respondents. In addition, important evidence is uncovered that shows creative class operates as an interactive variable, conditioning the effects of traditional determinants of tolerance. Conclusions. Evidence suggests that creative class or new political culture cities should be viewed as constituting distinctive cultural milieus that have important direct and interactive effects on tolerance attitudes. 相似文献

There is a considerable literature on transfer pricing. One strand of this literature is empirical and is concerned with the extent to which companies use the various transfer pricing methods. The other strand is strongly normative being directed to devising transfer pricing methods and defining the circumstances under which it is appropriate to use them. This study attempts to address both these questions by using discriminant analysis methods to predict which approach a company will use to determine transfer prices given its weightings of certain ‘determinants’ which theory suggests should be relevant to the decision. Domestic and international transfer pricing are considered separately. Discriminant analysis is shown to be quite successful in predicting the transfer pricing systems adopted by the UK companies surveyed. 相似文献

The 1970 census included numerous procedural innovations, of which the most important was the use of mail-out/mail-back techniques. A statewide survey of Wisconsin households (conducted in May and June, 1970) included questions designed to elicit information on the degree of cooperation rendered, ease of comprehension of the form, possible objectionable items on the census, whether or not contacts were made by enumerators, and respondent judgments of the adequacy of enumerators’ performance. The results indicate that Wisconsin respondents tended to comply with census procedures, that they found very little difficulty in filling out the mailed forms, and that they regarded the census enumerators as doing a “good job” in most cases. 相似文献

Although much research on household work has focused on young dual-career couples, there has been speculation that retirement may have a significant effect on the arrangement of household activities in later life. Furthermore, involvement in the household is believed to influence psychological well-being. Available literature, however, provides contradictory evidence regarding the extent to which integration into household activities may either reduce or contribute to stress. The degree to which male involvement in the household in later life was stressful was examined in this research. Data were analyzed from structured interviews with 1165 older, married men who were employed full-time, part-time, or retired. Employed men were significantly less involved in the household than were the retired; however, men participated more in both masculine and feminine tasks if their wives were employed. Involvement in the household was not stressful although the benefits derived from participation varied somewhat by type of task. 相似文献

An internal pilot with interim analysis (IPIA) design combines interim power analysis (an internal pilot) with interim data analysis (two-stage group sequential). We provide IPIA methods for single df hypotheses within the Gaussian general linear model, including one and two group t tests. The design allows early stopping for efficacy and futility while also re-estimating sample size based on an interim variance estimate. Study planning in small samples requires the exact and computable forms reported here. The formulation gives fast and accurate calculations of power, Type I error rate, and expected sample size. 相似文献

An inverse Gaussian mixture of Poisson distributions(the P-IG distribution) is considered as a model for species abundance data,, Minimum chi-square and maximum likelihood methods of estimation for the zero-truncated P-IG distribution are developed, Ihe performance of the P-IG distribution is illustrated and discussed for several well-known sets of insect abundance data. 相似文献
