Credibility, Information Preferences, and Information Interests 总被引:3,自引:1,他引:2
The Seveso Directive of the European Union demands that information be provided to the public by companies and authorities about facts, risks, and behaviors related to hazardous facilities, in particular chemical facilities. On behalf of the Commission of the European Communities, a survey was run in five European countries on the credibility of various information sources. This article describes the results of the German study. 430 persons were interviewed with a questionnaire of 50 items, in particular about their perceptions and evaluations of technical risks, the credibility of sources of information about chemical risks, their preferences for receiving risk information from these sources, and their interests in receiving information. Major findings are great differences in credibility, differentiated information preferences, and strong information interests. Surprisingly, credibility played only a minor role with regard to the respondents'information preferences and interests. 相似文献

Michel's notion of the inevitable and ironic transformation of groups with egalitarian intent into groups with oligarchical practices is examined through an analysis of thirty-four role playing partisan groups. Each group is a triad with an extended shared history or a history of equality that comes with friendship. Each group differentiated itself by selecting a representative to confront another student who played the role of a university dean. In nineteen of the groups the constituents obtained a news report of the outcome of those negotiations independent of their representative's report. In the other fifteen groups the constituents had to depend on their representative's report. In those groups that relied solely on their representative's report, oligarchical interrelations emerged. This contrasts with the news report groups who maintained egalitarian relationships while developing a political standpoint toward each other, the opposition and the future. We conclude that Michels' statement on organizational oligarchy is illuminated further by a consideration of an emergent monopoly of knowledge. 相似文献

The present article provides a quantitative overview of the state of coaching research. It first provides an insight into the status quo of the academic publishing landscape. Afterwards, results of the four meta-analyes that have been published on coaching research up to now are summarized. First, results on the efficacy of coaching or coaching outcomes are presented. Findings for different outcome measures as well as different study designs are reported. Next, results on predictors of coaching success are presented. They include specific features of the coaching process and setting, the coach-coachee-relationship as well as characteristics of coaches and coachees. The article closes with a summary and an assessment of the state of coaching research. 相似文献

There is a large and growing literature on welfare state attitudes, most of which is built on random-sample population surveys with standardised closed-question items. This article criticises the existing survey instruments, especially those that are used within the International Social Survey Programme, in a novel approach with focus group data from Germany. The article demonstrates: firstly, these instruments underestimate the inconsistency (the degree to which attitudes logically contradict each other), the uncertainty (the degree to which individuals are unsure about what to think), the ambivalence (the simultaneous occurrence of positive and negative reactions) and non-attitudes towards welfare state activities that common people have. Secondly, the meaning of these items to respondents seems to vary to such an extent that inference based on such measures is questionable. Finally, the article concludes by suggesting some survey instruments that alleviate these measurement problems. 相似文献

Whereas in theory individuals tend to postpone fertility decisions in times of economic uncertainty, empirical evidence on that question is scarce. Using data from the German Socio‐Economic Panel (N = 4,548), the authors estimated the effect of economic concerns on the probability of becoming pregnant in the next year. They exploited exogenous variation in economic concerns induced by the announcement of a major German unemployment benefit reform as an instrumental variable and found that strong economic concerns were significantly related to lower fertility of women between ages 26 and 44 years cohabiting with a male partner. Jointly estimating the impact of male and female concerns in a model that allows for endogeneity of perceived economic uncertainty revealed that it was strong economic concerns perceived by the women that reduced fertility. The effect was driven by male main breadwinner couples, by couples with a medium household income, and by couples who already had children. 相似文献

All Swedish court cases from 2004 and 2006 concerning alleged child sexual abuse (sexual harassment excluded) were identified through criminal registers. Fourteen cases (one boy) concerned a child with a neuropsychiatric disorder. The diagnostic groups were mental retardation (10 cases), autism (three cases), and ADHD (one case). Psychiatric experts were engaged in only two cases. When experts were involved, the courts focused on credibility issues. When the courts applied neuropsychiatric arguments in the absence of an expert, they used developmental arguments. When the authors found that significant neuropsychiatric issues were not discussed by the court it concerned interpretations of symptoms and developmental standpoints. The results illustrate the complexity and pitfalls of drawing conclusions about associations between symptoms and personality characteristics on one side and accuracy of sexual abuse allegations on the other. Moreover, the results highlight the importance of a high quality system for providing courts with adequate neuropsychiatric knowledge. 相似文献

In biology, medicine and anthropology, scientists try to reveal general patterns when comparing different sampling units such as biological taxa, diseases or cultures. A problem of such comparative data is that standard statistical procedures are often inappropriate due to possible autocorrelation within the data. Widespread causes of autocorrelation are a shared geography or phylogeny of the sampling units. To cope with possible autocorrelations within comparative data, we suggest a new kind of the Mantel test. The Signed Mantel test evaluates the relationship between two or more distance matrices and allows trait variables facultatively to be represented as signed distances (calculated as signed differences or quotients). Considering the sign of distances takes into account the direction of an effect found in the data. Since different metrics exist to calculate the distance between two sampling units from the raw data and because the test results often depend on the kind of metric used, we suggest validating analysis by comparing the structures of the raw and the distance data. We offer a computer program that is able to construct both signed and absolute distance matrices, to perform both customary and Signed Mantel tests, and to explore raw and distance data visually. 相似文献
