This longitudinal study explored the relationship between perceived breast cancer risk and worry. We measured both absolute and comparative risk perceptions, and also used the Gail algorithm to assess the accuracy of participants' risk perceptions. Three hundred and one women ages 40–75 participated in a two‐part study assessing how format of breast cancer risk presentation affected perceptions of risk. Relative to their Gail scores, women were biased pessimistically about their own absolute breast cancer risk and yet largely accurate about their comparative breast cancer risk. Perceived comparative risk, but not perceived absolute risk or biases in absolute or comparative risk, predicted subsequent worry. Worry predicted subsequent perceived absolute risk and biases in absolute and comparative risk. These results suggest that women's emotional reactions to breast cancer risk are based on accurate (unbiased) perceptions of their comparative risks. In turn, greater worry prompts a re‐evaluation of absolute risk as well as changes in risk biases. Implications for screening are discussed.  相似文献

Falls from publicly owned climbing equipment are often cited as the major cause of injury on children's outdoor playgrounds and have been the focus of substantial interventions in the UK since the early 1980s. Analysis of national data on falls from climbing frames for 1988 to 2002 shows that the main discernible trend during this period is an increase in the occurrence of injuries to the lower arm. Whether this is attributable to a behavioural response to some of the interventions, or to some other factor, is unknown.  相似文献

Wohnungsdesorganisation bei Sucht - Chaotische Wohnverh?ltnisse lassen sich oft auf eine Suchterkrankung zurückführen. Dabei kann man einen deutlichen Unterschied zwischen Wohnungen von Menschen mit einer Kaufsucht und denen von Menschen mit psychischen St?rungen und Verhaltensst?rungen durch psychotrope Substanzen beobachten.  相似文献

This study addresses the emergence of social liabilities by taking a social network perspective on intra- and interorganizational network configurations using the hitherto unexplored example of the corporate venture capital (CVC) triad (CVC unit, corporate business unit, and portfolio company). We investigate social capital and social liability resulting from network formation and transformation and assess their impact on interorganizational knowledge transfer and creation. Examining 12 CVC triads in Germany, we identify new antecedents of social liability, show that social capital can initially facilitate knowledge transfer and creation, and that structural and personal lock-ins may eventually turn that capital into a liability. We make key theoretical contributions to the social network and CVC literature.  相似文献

With consumers and their activities routinely visible through online, mobile and social media, to both their peers and to corporations, this article examines surveillance as a marketplace icon. Surveillance is central to the construction of consumers and markets. Many contemporary marketing practices are surveillant as they rely on the collection, analysis and application of consumer data to place advertising, define market segments and to nudge consumer behaviours. Consumer surveillance is also an enactment of corporate power, attempting to align individual preferences with corporate goals. The historical origins of surveillance and the emergence of the surveillance–industrial–entertainment complex are explored, which highlights how surveillance, as well as a process for defining markets is also an object of consumption. The future sees a huge struggle for consumer data between two great centres of surveillance power – the state and the corporation – as they battle over data use for national security.  相似文献

This study set out to examine environmental factors impacting on the food literacy of adolescents. It utilized data from a nation‐wide survey of home economics teachers regarding their experience of food literacy education in Australian high schools. Content analysis and the ANGELO framework were applied to analyse free‐text comments from 78 of the respondents that were collected as part of a more extensive data set. The analysis of environmental factors revealed three enablers and ten barriers that could influence food literacy education delivered by high schools in Australia. High schools are well positioned to improve adolescents’ food literacy through a comprehensive, hands‐on approach in home economics. However, many environmental barriers were reported that could influence food literacy education in Australian high schools such as: lack of teaching materials and facilities, and human resources; the perceived inadequacy of the Australian school curriculum; non‐supportive school canteens; and negative role modelling. This study points to the need to eliminate or reduce these environmental barriers impacting on the capacity for effective food literacy education in high schools to help adolescents increase their food literacy and thereby support them in making informed food choices.  相似文献
