This article provides the first controlled evaluation of how different information materials explaining the risks from radon influenced people's perceptions of these risks. Using a panel study, it was possible to observe how stated risk perceptions responded to information about indoor radon concentrations and brochures explaining the radon readings. The findings indicate that risk communication policies can be effective in modifying risk perceptions. Moreover, they have three specific implications for radon policy: (1) Public officials should not adopt strategies that provide minimal risk information to the public as a means of avoiding undue alarm, for this can have the reverse effect; (2) measures of the effectiveness of risk communication will depend on how education and behavior change are defined; (3) categorical guidelines about risk without quantitative information can lead people to treat the levels as thresholds, creating an artificial discontinuity in their responses to small changes in risk perceptions.  相似文献

This study investigates the relationship between postmaterial values and the New Environmental Paradigm in Canada (Ontario) and the United States (Michigan). Based on survey data collected among both citizens and environmental activists, it is evident that among both Canadian and American respondents of both citizen and activist type the two value dimensions are similarly multidimensional and separate. Rather than reflecting a single larger dimension of value orientation, as claimed by some, it is clear that the Inglehart postmaterialist value measure and the Dunlap and Van Liere NEP index are separate constructs in the thinking of the Canadians and Americans surveyed. While these findings were parallel in the Canadian and American settings, a number of cross-national differences in how these values influence attitudes and behaviors are reported. In general, these findings underscore the need to continue to focus on variations in the cultural context of citizen responses to postindustrial change.  相似文献

Components of loneliness during adolescence   总被引:1,自引:0,他引:1  
Predictors of adolescent loneliness were investigated in two samples of high school students (n=92)and college undergraduates (n=192).Results were similar across samples. Among the high school sample loneliness was significantly predicted by a combination of alienation, a lack of social facility and acceptance, inferiority feelings, negative school attitudes, and a lack of social integration. Among college students loneliness was negatively related to social facility, regularity, approval, and involvement and positively related to alienation, parental disinterest, negative school attitudes, and inferiority feelings.Research interests include loneliness and self-concept.Received Ph.D. in social psychology from Oklahoma State University. Research interests include loneliness and friendships.  相似文献

Ego identity and intimacy statuses were determined for 88 college students, 44 men and 44 women, and related to each other and to measures of intimacy, loving, and liking. As hypothesized, more advanced stages of identity development were associated with higher levels of intimacy formation. Further, for both males and females, occupational identity development was the primary predictive factor in the identity/intimacy stage resolution relationship.Received her M.

This study explores the role of income for young people with experience in foster care transitioning to adulthood. It draws on in-depth structured interviews with eight staff members and 38 current and former foster youths age 18 years and older, who were participants in an innovative program to build their assets and financial capability. Interviews took place in four sites in three states. This study illuminates how those with experience in foster care seek to obtain and manage money to transition successfully to adult financial roles. Findings suggest that early and practical experiences with money are important for gaining financial capability. The study also highlights the need for child welfare professionals to develop expertise in financial literacy and understand the pitfalls that lie in both traditional and nontraditional financial services. By deepening understanding among staff of the economic realities facing the young people today, child welfare agencies will be more likely to prepare former foster youths for life on their own.  相似文献

The rate for the sudden infant death syndrome (SIDS) in Cape Town, South Africa, is estimated to be among the highest in the world (3.41/1000 live births). In several of these areas, including those of extreme poverty, only sporadic, nonstandardized infant autopsy, and death scene investigation (DSI) occurred. In this report, we detail a feasibility project comprising 18 autopsied infants with sudden and unexpected death whose causes of death were adjudicated according to the 1991 NICHD definitions (SIDS, n = 7; known cause of death, n = 7; and unclassified, n = 4). We instituted a standardized autopsy and infant DSI through a collaborative effort of local forensic pathology officers and clinical providers. The high standard of forensic investigation met international standards, identified preventable disease, and allowed for incorporation of research. We conclude that an effective infant autopsy and DSI protocol can be established in areas with both high sudden unexpected infant death, and elsewhere.
