Three experimental studies were conducted employing hypothetical news stories to compare the effects on reader risk perceptions of two situations: when agency communication behavior was reported to be responsive to citizens' risk concerns, vs. when the agency was reported to be unresponsive. In the first two experiments, news stories of public meetings filled with distrust and controversy led to ratings indicating greater perceived risk than news stories reporting no distrust or controversy, even though the risk information was held constant. This effect appeared clearly when the differences in meeting tone were extreme and subjects made their ratings from their recall of the stories, but it was much weaker when the differences were moderate and subjects were allowed to go back over the news stories to help separate risk information from conflict information. In the third experiment, news stories about a spill cleanup systematically varied the seriousness of the spill, the amount of technical information provided in the story, and the agency behavior and resulting community outrage. The outrage manipulation significantly affected affective and cognitive components of perceived risk, but not hypothetical behavioral intentions. Seriousness and technical detail had very little effect on perceived risk.  相似文献

In practice, advertising is almost invariably regarded, as a tactical decision. It is shown that such an approach tends to systematically misallocate advertising and other resources among products. This paper shows why, in the modern multiproduct firm, advertising must be developed from a clear statement of strategy. It also reviews for managers some of the unresolved dilemmas in advertising planning.  相似文献

ABSTRACT

The purpose of this scoping review was to examine the literature on team resilience to gain insight into current thinking regarding its definition and conceptualisation, and to identify how researchers have operationalised and measured this concept. We conducted a systematic scoping review using the 5-phase approach proposed by Arksey and O’Malley. A total of seven databases were searched, followed by a citation search of eligible papers via Google Scholar. Of the 275 articles identified via the search process, 27 papers were deemed eligible for review. Several key findings regarding the literature on team resilience were observed: (i) definitions varied in terms of content (e.g. input or process), breadth (e.g. unidimensional versus multidimensional), and quality (e.g. essential and necessary attributes of key components); (ii) there was a predominance of single-level conceptualisations of team resilience; and (iii) there has been a reliance on cross-sectional research designs in empirical studies, which is incongruent with the dynamic nature of this concept. Key recommendations from this scoping review focus on definitional, theoretical, and methodological issues.  相似文献

Little is known about the characteristics of adolescent sex offenders who do not reoffend. Most studies emphasize reoffense rates, recidivism and those who reoffend. Moreover, these studies provide quantitative summaries without describing the individual, his behavior, and challenges after treatment. The present study seeks to provide novel information about the life experiences of adolescent sex offenders who have not reoffended after reentering society. Through a structured questionnaire and an in-depth qualitative interview, the adolescents (N = 7) provided information regarding their life experiences after treatment with an emphasis on the challenges they face in society.  相似文献

This study examined the relationship of ambivalent sexism, political conservatism, demographic variables (age, education, and gender), and prior sexual experience to Turkish men s and women s attitudes toward women who engage in premarital sex. Participants included 124 Turkish undergraduate students and 60 nonstudent Turkish adults. Benevolent but not hostile sexism uniquely predicted more negative views of women who engage in premarital sex once other variables were controlled. Regression analyses demonstrated that for both men and women, older, more politically conservative and less sexually experienced respondents and more educated men (but not women) respondents were more likely to disapprove of women who engage in premarital sex. Similarly, regression analysis revealed that men who were older, politically conservative, and less sexually experienced expressed stronger preferences for marrying a virgin. Both hostile and benevolent sexism predicted men s preference for marrying a virgin after all other variables were controlled.  相似文献

Touraine's method of Sociological Intervention (SI) for the analysis of social movements is examined in the light of a case study of Local Exchange Trading Schemes (LETS). Tempered by Melucci's critique of Touraine's attempt to find one ‘higher’ meaning of a social movement. LETS was examined using a staged series of focus groups to uncover and illuminate the extent that LETS can be regarded as a social movement. The appropriateness of SI as a method within the resource constraints of a small study is discussed, and SI is recommended as an effective method of examining emerging social movements if triangulated with other methodological approaches.  相似文献

Traditionally, studies of disabled people's access to the labour market have been largely restricted to labour market 'censuses', often conducted by government agencies, and econometric studies. This paper explores disabled people's access to and experiences of employment in Donegal, West Ireland, using a qualitative approach. Twelve disabled people and four non-disabled helpers, divided into two focus groups, were interviewed using an in-depth, informal conversational strategy. A number of different, salient issues were identified in regards to training, and gaining and maintaining employment, ranging from ignorance and discrimination, to poor access (both workplace and transport), to legislation. Respondents identified a number or potential solutions which mainly focused around disability awareness, removing barriers to gaining employment and the implementation of stronger legislation. In the final section, the issues and solutions raised by disabled people are compared to those identified by non-disabled people, collected in a parallel study.  相似文献

Using a range of examples, the paper argues that there is an information deficit concerning early childhood services; even on the most basic issues, there is either no information or such information as does exists is unreliable, limited or outdated. This matters because information is a necessary condition for good policy, for open and democratic decision making and for giving visibility to young children. The article concludes by considering how an adequate information system might be developed based on annual returns from individual services and regular surveys of households with children.  相似文献

The paper derives bounds on the distribution of the quadratic forms Z = y H( X Γ X H)−1 y and W = y H2 I + X Γ X H)−1 y , where the elements of the M × 1 vector y and the M × N matrix X are independent identically distributed (i.i.d.) complex zero mean Normal variables, Γ is some N × N diagonal matrix with positive diagonal elements, I , is the identity, σ2 is a constant and H denotes the Hermitian transpose. The bounds are convenient for numerical work and appear to be tight for small values of M . This work has applications in digital mobile radio for a specific channel where M antennas are used to receive a signal with N interferers. Some of these applications in radio communication systems are discussed.  相似文献
