Men's limited movement into female occupations has been identified as a key barrier to future declines in occupational sex segregation and achieving greater gender equality. So why are men so reticent to enter jobs normatively regarded as female? Drawing from qualitative interviews with multiple stakeholders in four female‐dominated occupations in Australia, this article documents the processes that influence men's employment in gender‐atypical jobs. Gender essentialism is central to many processes that generate and/or stall changes in men's representation in female‐dominated occupations. While gender essentialism's role in producing and reproducing occupation sex segregation is well known, its role in reducing occupational sex segregation is a critical process which has previously received limited attention. The article details gender essentialism's integrative function. 相似文献

After observing ostracism or social exclusion, older children, adolescents and adults report decreased satisfaction of the need for control. Attempting to regain control can motivate aggression in ostracized adults. Research has shown that the onset of ostracism’s harmful effects on children’s behavior is at preschool age. We investigated whether preschoolers would exert more control after witnessing ostracism. A sample of 53 children (Mage = 5 years, 5 months) first watched priming videos either showing ostracism or not. Subsequently, they participated in two ball games. In both of the games (order counterbalanced), children could control the flow of a ball’s motion, either live between two people (i.e., social control) or between two bars on a laptop screen (i.e., non‐social control). Overall, children understood social exclusion when it was displayed in the videos. We found an effect of observed ostracism only on social control. Four‐ to five‐year‐old boys who witnessed ostracism stopped a ball game between two persons longer than boys who did not witness ostracism. Our results suggest that observing social exclusion elevates young boys’ need for control over a social situation. Girls showed a different pattern but their responses did not differ significantly between ostracism and non‐ostracism conditions. 相似文献

Fuzzy-trace theory predicts that decisionmakers process numerical information about risk at multiple levels in parallel: the simplest level, nominal (categorical some-none) gist, and at more fine-grained levels, involving relative comparison (ordinal less-more gist) and exact quantities (verbatim representations). However, little is known about how individual differences in these numerical representations relate to judgments and decisions, especially involving health tradeoffs and relative risks. To investigate these differences, we administered measures of categorical and ordinal gist representations of number, objective numeracy, and intelligence in two studies (Ns = 978 and 956). In both studies, categorical and ordinal gist representations of number predicted risk judgments and decisions beyond objective numeracy and intelligence. Participants with higher scores in categorical gist were more likely to choose options to avoid cancer recurrence risks; those who were higher in ordinal gist of numbers were more likely to discriminate relative risk of skin cancer; and those with higher scores in objective numeracy were more likely to choose options that were numerically superior overall in terms of relative risk of skin cancer and of genetic risks of breast cancer (e.g., lower numerical probability of cancer). Results support parallel-processing models that assume multiple representations of numerical information about risk, which vary in precision, and illustrate how individual differences in numerical representations are relevant to tradeoffs and risk comparisons in health decisions. These representations cannot be reduced to one another and explain psychological variations in risk processing that go beyond low versus high levels of objective numeracy. 相似文献

Consumer Selection of Food-Safety Information Sources 总被引:1,自引:0,他引:1
The aim of this study is to examine the preferences of consumers for different information sources when they have a question about food safety. On the basis of a nationally representative survey conducted in the Netherlands, five distinct consumer groups are identified that not only differ on the reported use of information sources but also regarding several personality characteristics and sociodemographic variables. The empirical results show that two-thirds of the consumers are selective in their use of information sources and prefer either institutional or social sources. So, multiple information-acquisition patterns exist among the general public. The study illustrates how these findings can help to develop effective risk communication strategies. 相似文献

We present two experiments investigating the role of emotions concerning technological and natural hazards. In the first experiment, technological hazards aroused stronger emotions, and were considered to be riskier than natural hazards. No differences were found between the texts versus audio presentations. However, the presence of pictures aroused stronger emotions and increased the perceived risk. Emotions play a mediating role between hazard types and perceived risk, as well as between pictures and perceived risk. The second experiment adopted real‐world materials from webpages and TV. Emotions again play a mediating role between pictorial information and risk perception. Moreover, specific emotions were found to be associated with different types of action tendencies. For example, loss‐based emotions (e.g., fear, regret) tend to lead to prevention strategies, whereas ethical emotions (e.g., anger) lead to aggressive behavior. We also find that loss‐based emotions in the technical hazard scenario trigger more coping strategies (from prevention to retaliation) than in the natural hazard scenario. 相似文献

In many toxicological assays, interactions between primary and secondary effects may cause a downturn in mean responses at high doses. In this situation, the typical monotonicity assumption is invalid and may be quite misleading. Prior literature addresses the analysis of response functions with a downturn, but so far as we know, this paper initiates the study of experimental design for this situation. A growth model is combined with a death model to allow for the downturn in mean doses. Several different objective functions are studied. When the number of treatments equals the number of parameters, Fisher information is found to be independent of the model of the treatment means and on the magnitudes of the treatments. In general, A- and DA-optimal weights for estimating adjacent mean differences are found analytically for a simple model and numerically for a biologically motivated model. Results on c-optimality are also obtained for estimating the peak dose and the EC50 (the treatment with response half way between the control and the peak response on the increasing portion of the response function). Finally, when interest lies only in the increasing portion of the response function, we propose composite D-optimal designs. 相似文献

为研究未来江苏省补充养老保险替代率变化状况,在分析制度替代率的基础上,建立了测算模型,分别对江苏省2010—2030年不同性别的职工做预测。结果显示:江苏省补充养老保险替代率具有明显的性别差异,制度对不同性别参保职工退休后生活水平的影响差别悬殊,超过制度起初设计的目标。逐步提高缴费率、延长退休年龄特别是女性职工的退休年龄,是提高女性职工补充养老保险金替代率的关键。 相似文献
