Nanotechnology involves the fabrication, manipulation, and control of materials at the atomic level and may also bring novel uncertainties and risks. Potential parallels with other controversial technologies mean there is a need to develop a comprehensive understanding of processes of public perception of nanotechnology uncertainties, risks, and benefits, alongside related communication issues. Study of perceptions, at so early a stage in the development trajectory of a technology, is probably unique in the risk perception and communication field. As such it also brings new methodological and conceptual challenges. These include: dealing with the inherent diversity of the nanotechnology field itself; the unfamiliar and intangible nature of the concept, with few analogies to anchor mental models or risk perceptions; and the ethical and value questions underlying many nanotechnology debates. Utilizing the lens of social amplification of risk, and drawing upon the various contributions to this special issue of Risk Analysis on Nanotechnology Risk Perceptions and Communication, nanotechnology may at present be an attenuated hazard. The generic idea of "upstream public engagement" for emerging technologies such as nanotechnology is also discussed, alongside its importance for future work with emerging technologies in the risk communication field. 相似文献

Each day for five days, 79 fifth‐grade children reported on events that occurred at school and they and their parents described their interactions with each other each evening. Consistent with previous research, it was found that on days when children reported more academic or peer problems during the day at school, they later described more aversive interactions with their parents. As hypothesized, increases in anxiety and drops in children's state self‐esteem partially mediated this link. However, parents did not report any differences in their interactions with the target child on days when the child experienced problems at school. This study suggests that negative events experienced by children while at school lead to short‐term changes in mood and self‐esteem, which influence their perceptions of subsequent interactions at home with parents. 相似文献

Analysis of 1995 Vremya (Russian national television) newscasts reveals few traces of the cold-war framework that dominated news media discourse throughout the world for almost four decades. The ability of Vremya to reconstruct its images of Russia and the United States reaffirms the contention of Edelman, Hall, and others that media news accounts evoke a spectacle that is an ideological product, not a set of facts. The spectacle of politics is a fetish, a creation that then dominates the thought and action of its creators. 相似文献

In clinical work, we have observed that the loss of the father through divorce has a significant effect on the young girl's developing sense of feminity. This paper briefly reviews the research findings from sex-role development theory and psychoanalytic theory, and presents clinical discussions of latency aged girls whose parents divorced during their daughter's early and oedipal years. The most common defensive or coping patterns seen in these child patients during latency are identified, with clinical material presented to illustrate both the existence of these patterns and implications for treatment. 相似文献

CEOs affect corporate outcomes along various dimensions, including the emphasis placed on long-term strategic planning. This study assesses the impact of CEOs’functional and industry specializations on R&D and capital spending in four manufacturing industries. We found only limited support for our position that CEOs with more professional-type careers are less willing than other CEOs to have their firms make long-term investments. “A critical theme of… the modem industrial enterprise is that creating and maintaining such capabilities is a continuing, long-term process–a process that requires sound, long-term perspectives from the decision makers responsible for the health and growth of their enterprise.” (Chandler 1991, p. 627) 相似文献

We present a hypothetical case study using the Years of Potential Life Lost (YPLL) metric to compare cancer risks incurred by residents living near a Superfund site to occupational fatality risks incurred by workers employed in that site's remediation. Since cancer occurs late in life, and because we assume its mortality rate is 60%, each case results in 8.8 YPLL. Each occupational fatality, which typically occurs earlier in life, results in 38.1 YPLL. In our case study, the residential population of 5000 incurred 1.3 YPLL, compared to 5.7 YPLL incurred by the 500 workers. Several uncertain assumptions may influence our calculations; moreover, occupational risks may be viewed as more "voluntary" than risks incurred by residents. However, because the magnitude of the YPLL incurred by workers and residents may be comparable, risk managers should consider occupational risks when evaluating remedial alternatives. 相似文献

Depression is one of the most commonly diagnosed psychiatric disorders among school-aged youth, with high prevalence and far-reaching
consequences. However, even though there are two evidence-based practices for treating adolescent depression (Cognitive-Behavioral
Therapy and Interpersonal Therapy), most adolescents referred for treatment are unlikely to receive either. In part, this
is due to the difficulty of transporting an evidence-based practice from laboratory to real-world setting, and determining
how to transport an empirically validated treatment has thus become a focus of concern for social work researchers and practitioners.
A host of client, clinician, setting, and treatment delivery variables can influence portability. Taking all these factors
into consideration is a daunting task—but less daunting if done at the onset, during the initial process of efficacy research,
rather than afterward as a separate stage. The thesis of this paper is that the only solution to the problem of portability
is a combined, rather than sequential, approach to treatment development in which effectiveness and application concerns are
included in the original research design. A review of suggested approaches, as well as discussion of factors that contribute
to variance in outcome, is followed by recommendations for future research. 相似文献

Two studies of working families are combined to demonstrate a strategy for producing reliable estimates from the combination of self-reported (large N) and observational (small N) data. Both studies examine where and how dual-career families spend time at home. The 500 Family Study is sociological and uses self-reported time diary data from a national sample; the CELF study is anthropological and uses observational scan sampling data from a regional sample of 32 families. The data are combined as if they constitute one sample, and an analytic solution for establishing the reliability of the resulting composite estimates of time use is provided. Merging the data sets provides validation for each study, neither of which is without potential methodological weaknesses. The advantages of combining data from the independent data collection methods are discussed, and selected substantive findings on families' activities are highlighted, illustrating similarities and differences between findings in the independent and combined data sets. Results show that working families spend significant time in a small spectrum of home spaces, particularly kitchens and living rooms, with leisure activities prevailing, but mothers, fathers, and children differ in where and how they spend their time. Overall, a template for merging data from different disciplines and methods is provided. 相似文献
