In a content analysis of movie violence, we randomly selected twelve top-grossing American war films from four decades (1970 to 2002). We coded for implements of violence, length of violence, gore, and violence directed at noncombatants. We hypothesized that recently released war movies would be more violent than those released earlier. We found that films released since 1990 did contain more violence compared to others. Further, the intensity of gore increased in recently released movies.  相似文献

Environmental policymakers and regulators are often in the position of having to prioritize their actions across a diverse range of environmental pressures to secure environmental protection and improvements. Information on environmental issues to inform this type of strategic analysis can be disparate; it may be too voluminous or even absent. Data on a range of issues are rarely presented in a common format that allows easy analysis and comparison. Nevertheless, judgments are required on the significance of various environmental pressures and on the inherent uncertainties to inform strategic assessments such as “state of the environment” reports. How can decisionmakers go about this type of strategic and comparative risk analysis? In an attempt to provide practical tools for the analysis of environmental risks at a strategic level, the Environment Agency of England and Wales has conducted a program of developmental research on strategic risk assessment since 1996. The tools developed under this program use the concept of “environmental harm” as a common metric, viewed from technical, social, and economic perspectives, to analyze impacts from a range of environmental pressures. Critical to an informed debate on the relative importance of these perspectives is an understanding and analysis of the various characteristics of harm (spatial and temporal extent, reversibility, latency, etc.) and of the social response to actual or potential environmental harm from a range of hazards. Recent developments in our approach, described herein, allow a presentation of the analysis in a structured fashion so as to better inform risk‐management decisions.  相似文献

The autoregressive conditional intensity model proposed by Russell (1998) is a promising option for fitting multivariate high frequency irregularly spaced data. The authors acknowledge the validity of this model by showing the independence of its generalized residuals, a crucial assumption of the model formulation not readily recognized by researchers. The authors derive the large‐sample distribution of the autocorrelations of the generalized residual series and use it to construct a goodness‐of‐fit test for the model. Empirical results compare the performance of their test with other off‐the‐shelf tests such as the Ljung–Box test. They illustrate the use of their test with transaction records of the HSBC stock.  相似文献

An Experiment in Helping Foster-Carers Manage Challenging Behaviour   总被引:1,自引:0,他引:1  
A randomized controlled trial was implemented with groups offoster-carers to test the effectiveness of cognitive–behaviouralmethods in the management of difficult behaviour. Contrary toexpectations, no statistically significant differences werefound between the groups with regard to behaviour managementskills, the frequency and/or severity of behavioural problems,and placement stability. In contrast, foster-carers expressedsatisfaction with the overall training programme and increasedconfidence in dealing with difficult behaviour. Discussion ofthe results focuses on a number of competing explanations forsuch findings and concludes with recommendations for futurework.  相似文献

Questionnaires were administered to 70 black female, 75 black male, 1,457 white female and 1,429 white male university freshmen. In order to test three alternative theories regarding perceptions of discrimination, analyses of variance related sex, race, and SES to total scores of perceived occupational discrimination against blacks (BDST) and against women (WDST). Blacks perceived significantly more discrimination against black people than did whites; neither sex nor SES differentialed scores on BDST. Black females and white males perceived significantly more discrimination against women than did white females; black females had the highest and white females the lowest WDST scores. A discriminant analysis on white females indicated that high WDST scorers were characterized by an “underdog syndrome” whereas low WDST scorers held internal, individualistic values. The findings indicated the greatest support for the formulation that differential anticipatory socialization into the role of “a person who is discriminated against” characterized white females who perceived more or less discrimination against women.  相似文献

The paper analyses the distribution of times from HIV seroconversion to the first AIDS defining illness for a subcohort of the Western Australian HIV Cohort Study for whom the seroconversion date is known to fall within a calendar time window. The analysis is based on a generalised gamma model for the incubation times and a piecewise constant distribution for the conditional times of seroconversion given the seroconversion windows. This allows flexible hazard shapes and also allows comparison of goodness of fit of the gamma and Weibull distributions which are often used for modelling incubation times. Computational issues are discussed. In these data, neither age at seroconversion, nor calendar time of seroconversion, nor the identification of a seroconversion illness appears to afFect incubation distributions. The Weibull distribution appears to provide a reasonable fit. The distribution of times from seroconversion to an HIV-related death is also briefly considered.  相似文献

In this article I outline a principled social psychological approach to respect. As a first definitional approximation, I suggest that respect for someone involves the willingness to include that person as a factor in the psychological equation underlying self-regulation. I then review and discuss the fairly recent, but thriving, career of the notion of respect in social psychological research, with particular emphasis on intragroup respect. Next, I turn to conceptual specification and purification necessary for a principled approach to respect and discuss promising efforts to identify the critical social psychological principle or active ingredient of respect. In particular, I make out a case for an equality-based conception of respect in which recognition as an equal plays a central role. The final section examines further theoretical and practical implications of this conception including its relation and relevance to issues of social power. Bernd Simon (Dipl.-Psych., Dr. habil.) is Professor of Social Psychology and Evaluation Research and one of the Directors of the Institute of Psychology at the Christian-Albrechts-University in Kiel (Germany). He studied psychology, sociology and philosophy at the University of Münster (Germany) and the University of Kent at Canterbury (England). In his research, Bernd Simon investigates inter-and intragroup processes, with particular emphasis on issues of identity, power, politicization and respect. He is author/co-author of a number of research articles in international journals and books, including Identity in Modern Society (Blackwell Publishing).  相似文献
