A discussion of the 1980 U.S. census is presented. The authors suggest that the taking of a national census is not just a statistical exercise, but an exercise involving ethics, epistemology, law, and politics. They contend that conducting a national census can be defined as an ill-structured problem in which the various complexities imposed by multidisciplinarity cannot be separated. "The 1980 census is discussed as an ill-structured problem, and a method for treating such problems is presented, within which statistical information is only one component." 相似文献

Blacks, whites, and attitudes towards abortion 总被引:1,自引:0,他引:1
This article examines patterns of black and white support forabortion from 1972 to 1980. The findings reveal that black-whitedifferences are present on the abortion issue. Many of the differencesare due to the different demographic characteristics of blacksand whites and the greater degree of religiosity of blacks. 相似文献

The "positivity bias" is a term used to describe the consistentfavorable evaluation of public figures found in surveys overthe past 40 years. This paper explored several possible artifactualexplanations for this bias,focusing on the survey instrumentitself. Two experiments varied the labeling and ordering ofscale endpoints, the affective value of the initial contextevaluated, and the presence or absence of a prestigious jobtitle associated with the nameof the public figure. None ofthe variations produced significantly different levels of positivitythan the standard control condition used in each experiment.RichardR.

In this note, the independence of X and S2 is proved without the prerequisite knowledge of differential calculus. The purpose is to compensate for the lack of a text in applied statistics that proves the independence of such statistics. 相似文献

We investigate mortality differentials by marital status among older age groups using a database of mortality rates by marital status at ages 40 and over for seven European countries with 1 billion person-years of exposure. The mortality advantage of married people, both men and women, continues to increase up to at least the age group 85-89, the oldest group we are able to consider. We find the largest absolute differences in mortality levels between marital status groups are at high ages, and that absolute differentials are: (i) greater for men than for women; (ii) similar in magnitude across countries; (iii) increase steadily with age; and (iv) are greatest at older age. We also find that the advantage enjoyed by married people increased over the 1990s in almost all cases. We note that results for groups such as older divorced women need to be interpreted with caution. 相似文献

The paper describes a methodology to be used for analysis and design of human activity systems. The methodology is based on an analysis of the decision settings whereas most other decision analysis methodologies are analysing the process. The decision concept is analysed and discussed. A distinction between programmed and programmable as well as non-programmed and non-programmable decisions is proposed. A classification of different information types for decision making is presented. A methodology based on a systemic and systematic analysis of the information requirements of an organization is proposed. This methodology also indicates organizational discrepancies and information imbalances. The methodology focuses the settings of the decisions on all levels of organizations. The methodology can be regarded as a dynamic, learning system. The author proposes further research on the individuals decision making abilities. 相似文献

Popular or media portrayals have suggested that many suburban housewives are dissatisfied with a number of aspects of their lives. This claim was investigated by surveying two groups of Brisbane women. Data obtained firstly from a sample at a shopping town and secondly from the members of a women's social club suggests that the dissatisfaction with the role of housewife expressed in the media may be overstated. Women find a lack of social contacts with others to be acute but report satisfaction with other aspects of their lives. Tentative solutions to facilitate social contacts between women are suggested. 相似文献
