Network Evening News Coverage of Environmental Risk   总被引:2,自引:0,他引:2  
ABC, CBS, and NBC's carefully crafted and expensively produced evening news broadcasts devoted 1.7% of their air time to 564 stories about man-made environmental risks during the period from January 1984 to February 1986. Little relationship was found between amount of coverage and public health risk. Instead, the networks appeared to be using traditional journalistic determinants of news (timeliness, proximity, prominence, consequence, and human interest) plus the broadcast criterion of visual impact to determine the degree of coverage of risk issues. Government, industry, and citizens accounted for two-thirds of the sources cited by the networks. Experts and spokespersons for environmental advocacy groups were sparsely used as sources. Given the media's need for news pegs, acute and chronic risk stories were covered differently. Acute risk stories were reported in a clearly defined cycle, peaking on the second day with on-the-scene reports and film-clips of devastation. In keeping with a decrease in visual drama, later reports were shorter and emphasized legal and political considerations. Chronic risk coverage followed the release of new scientific, legal, or political information.  相似文献

This qualitative study is designed to explore how women at various stages of lesbian identity development make decisions about managing their identities. Management of identity was studied in terms of how women came out or stayed hidden and how they made decisions both to disclose and to conceal. The Cass (1984) Stage Allocation Measure was used as a means to categorize women at various stages of lesbian identity development. Twenty-five adult women were individually interviewed using a semi-structured interview schedule. A journal was kept by each woman for one month. The major findings indicated that women at different stages of lesbian identity development use both disparate and similar identity-management and decision-making strategies. Underlying and connecting lesbian identity management and development was the need to maintain self-esteem and safety.  相似文献

British Children and Televised Violence   总被引:1,自引:0,他引:1  
Is the frequency of watching television programs with recurrentviolent themes positively related to aggressive attitudes amongyoung people? This study of a sample of British school childrenyields findings very similar to U.S. data, in terms of bothdirection and magnitude of the relationship. It also examinesthe influence of program type and demographic variables on thatrelationship.  相似文献

In a 1996 article on family theory, we (Green & Werner) proposed that family enmeshment should not be equated with high cohesion and that the construct of enmeshment fails to discriminate between two distinct relationship processes: Closeness-caregiving and intrusiveness. In this study, our model of these two independent dimensions of family connectedness was tested by assessing spouses from 264 couples, using the California Inventory for Family Assessment (CIFA). The CIFA scales showed acceptable reliability. Significant interspouse validity correlations also were obtained. As predicted by our theory, factor analyses distinguished dimensions of intrusiveness (blurring of boundaries) from dimensions of closeness-caregiving (such as warmth and nurturance). On all but two factors, behaviors of only one spouse (but not of both) had interpretable loadings. That is, in most areas, the two spouses' behaviors did not load together to form meaningful factors. The latter finding suggests that family systems theory--with its central notion of reciprocally contingent behaviors between family members--may be useful in understanding only a few dimensions of spouses' behavior (such as reciprocal aggression) whereas personality-in-context theories may be better for understanding most other dimensions (such as warmth and nurturance).  相似文献

A survey of 798 New Jersey residents examined relationships among residents' neighborhood activities, perceptions of neighborhood quality, trust of experts, support for rebuilding cities and equal rights, and degree of optimism. Neighborhood activities increased with lack of trust and optimism. These personality characteristic measures were folded into multidimensional constructs that included local environmental hazards, respondents' ratings of their previous neighborhoods, and some demographic variables. Pessimism and values that support equal rights and rebuilding cities were weakly associated with poor quality neighborhood ratings.  相似文献

Zedler  Joy B.  Leach  Mark K. 《Urban Ecosystems》1998,2(4):189-204
Conservation of urban wetland habitat is challenging, because multiple uses must coexist. We use examples from California and Wisconsin to describe potential synergies among recreation, restoration and research activities (the 3 R's). Allowing passive recreation is often essential to garner public support for habitat protection, restoration, and research. In turn, restoration activities can improve the appearance of degraded sites, and designing the work as a research experiment can serve the scientific community. Two projects at Tijuana Estuary support the 3 R's. (1) Oneonta Tidal Linkage is a 0.7-ha tidal channel and salt marsh that was excavated from disturbed upland to bring wetland habitat closer to the Visitor Center (thereby reducing visitor intrusion into natural marsh habitat, where endangered species would be disturbed). It supports an ambitious field experiment that is testing the importance of species diversity in restoration; it also includes a bridge that serves the interpretive program, and it adds 0.7 ha of wetland habitat that helps restore regional biodiversity. (2) A larger excavation (8 ha) of former tidal wetland will soon add wetland habitat, while testing the importance of tidal creek networks in ecosystem functioning and offering views and interpretive opportunities. A third situation, at the 485-ha University of Wisconsin–Madison Arboretum, concerns restored wet prairies, which provide habitat for native species and serve many hikers. Urban stormwater flows into and degrades the Henry Greene Prairie, allowing aggressive plants to invade. Research and restoration efforts are planned to sustain the habitat and recreation functions. These three models suggest that recreation, restoration, and research are compatible uses of urban wetland habitats.  相似文献
