Building on an earlier analysis of this data set, this study investigates the association between respondents' gender-stereotyping of city councillors with respect to work-related capabilities and their support for female representation on city council under conditions of low information. The earlier research found substantial gender-stereotypic bias in respondents' judgments about the office-related capabilities of male and female city council members. This analysis finds that the more positively women's capabilities to perform in office are evaluated, the more support there is for increased female representation on city council. In general, being “qualified” gets a candidate support but being female, for the most part, does not garner additional support. The double bind of this situation, however, is that female candidates are at a disadvantage because voters (in the sample) see men generically as being more able to meet the demands of serving on city council and increased female representation on city council can not occur unless individual female candidates are elected. 相似文献

Helen Clough and Patrick Brown are statisticians working in a cross-disciplinary veterinary epidemiology collaboration, uniting statisticians, mathematical modellers, veterinarians, molecular biologists and microbiologists. They describe the strengths that statisticians bring to the collaboration and the creative tensions that arise when both statistical and mathematical modelling techniques are used. 相似文献

Summary
Estimates in simple linear regression which minimize the sum of absolute values of residuals are discussed. These estimates, called median-estimates , are an analogue of the sample median, and their properties reflect this. A simple graphical procedure, related to an early (1923) one of Edgeworth, is outlined for computing median estimates. This method works well in small or moderate samples, and is demonstrated on two examples. The small sample distribution of the median estimates is examined by conditioning on the pattern of signs of the residuals, and the resulting conditional distribution gives qualitative information on the adequacy of the approximation of the exact distribution by the (known) asymptotic distibution. 相似文献

The development of social care policy for elderly Australians is proceeding with little regard for the preferences and perspectives as expressed by the elderly themselves. The likely consequence is a continuation of policies based largely on other people's assumptions about what elderly people actually need and the extension of service categories into which many elderly people do not easily fit. Discussions with 71 elderly consumers during 1983 in Queensland established that they have input to make into policy and service delivery issues such as the provision of information on services, the determination of needs, the extension of choices between alternative services and choice of appropriate service providers. Social care policy should not continue to develop around singular and untested assumptions concerning what elderly people need and prefer. 相似文献

We consider animal bioassay experiments with variable dosing regimens in which groups of animals are dosed beginning at different ages and for varying durations. Two response models are discussed and then applied to data from an experiment on vinyl chloride exposure of F-344 rats, B6C3F1 and Swiss CD-1 mice, and Syrian Golden hamsters. The multistage model of Armitage and Doll, as extended by Whittemore, Day and Brown, and Crump and Howe, is used to estimate the dose effect on the ordered stages of tumor development. The data for all endpoints and species/strains examined consistently indicate a predominant effect on the first stage, suggesting that vinyl chloride is primarily a tumor initiator. This is consistent with evidence from two-stage experiments on this chemical. The second response model, new to this article, adjusts for survival nonparametrically. It is used to test for an age difference in susceptibility, to evaluate alternative exposure durations, and to compare the effectiveness of alternative dosing regimens for detecting carcinogenicity. 相似文献
