This study investigates appraisal and coping behaviours, and symptom and expectation outcomes following a critical incident and Critical Incident Stress Debriefing (CISD). Two groups of 30 Australian police officers from the New South Wales Police Service who had been involved in shooting incidents were examined. One group received CISD and the other did not. The group that received CISD showed a significant reduction in anger levels and greater use of some specific adaptive coping strategies. However, one cannot be certain as to the extent of CISD's contribution to this improvement, since a variety of other factors in the officers' lives, as evidenced by other measures taken throughout the study, may help to explain the variation. Results are discussed in light of the contextual features in officers' lives that impact upon the outcome responses to such incidents. 相似文献

This article explores the state of research on the 'movement of movements' against neoliberal globalisation. Starting from a general consideration of the significance of the movement and the difficulties inherent in studying it, it discusses the literature on the movement from within social movement studies, and argues that the response from social movement researchers falls short of what could be expected in terms of adequacy to the movement and its own knowledge production. It explores some effects of this failure and locates the reasons for it in the unacknowledged relationship between social movements theorising and activist theorising. The article then discusses the possible contributions that can be made by Marxist and other engaged academic writers, as well as the significance of the extensive theoretical literature generated by activists within the movement. It concludes by stating the importance of dialogue between activist and academic theorising and research in attempting to understand the movement. 相似文献

This paper analyzes the impact of production uncertainty on the firm's optimal output decision. If uncertainty is introduced by an additive risk variable, then short-run optimal output is unchanged, but the owner-manager's expected utility can change causing long-run output effects. If uncertainty is introduced by a multiplicative random variable, then short-run output can change as well. 相似文献

Using former maps, geographers intend to study the evolution of the land cover in order to have a prospective approach on the future landscape; predictions of the future land cover, by the use of older maps and environmental variables, are usually done through the GIS (Geographic Information System). We propose here to confront this classical geographical approach with statistical approaches: a linear parametric model (polychotomous regression modeling) and a nonparametric one (multilayer perceptron). These methodologies have been tested on two real areas on which the land cover is known at various dates; this allows us to emphasize the benefit of these two statistical approaches compared to GIS and to discuss the way GIS could be improved by the use of statistical models. 相似文献

McConalogue (1980) describes an extension t o the Clérour-McConalogue cubic splining algorithm which permits the convolution of distributions whose densities exhibit a singularity at the origin. Reasons for generalising the original algorithm are discussed and a brief survey of other methods for numerical convolution is given. An example illustrates an application of the extended algorithm. 相似文献

The impact of a Tax-Based Incomes Policy on U.S. macroeconomic performance: An optimal control study
This study attempts to estimate the potential impact of a Tax-Based Incomes Policy (TIP) on macroeconomic performance by applying an optimal control algorithm to the Wharton Quarterly Econometric Model. A TIP is any tax incentive that would induce firms and/or workers to reduce wage increases. Our study is applicable to any version of TIP. To isolate TIP's potential impact, we compare the optimal path of the economy without TIP to the optimal path of the economy with TIP. Our conclusion is that a TIP may be able to significantly improve the path of inflation, unemployment, and real GNP simultaneously. 相似文献

This article reviews current literature examining associations between components of the family context and children and adolescents' emotion regulation (ER). The review is organized around a tripartite model of familial influence. Firstly, it is posited that children learn about ER through observational learning, modeling and social referencing. Secondly, parenting practices specifically related to emotion and emotion management affect ER. Thirdly, ER is affected by the emotional climate of the family via parenting style, the attachment relationship, family expressiveness and the marital relationship. The review ends with discussions regarding the ways in which child characteristics such as negative emotionality and gender affect ER, how socialization practices change as children develop into adolescents, and how parent characteristics such as mental health affect the socialization of ER. 相似文献

This study examined the impact of television program sexual content and explicit sexual advertisement content on memory for advertisements. Eighty-two French participants, aged 18 to 48 years, watched either a sexual program (Sex and the City) or a nonsexual program (Friends), with three sexual and three nonsexual adverts embedded within it. They then completed free- and cued-recall questionnaires testing their memory of the advertisements, as well as a gender identity scale. Overall, sexual advertisements were recalled (in free recall) better than nonsexual advertisements. Participants were found to recall adverts significantly better within the nonsexual program than within the sexual program. No interaction was found between program type and advertisement type: Sexual adverts were recalled better than nonsexual adverts within both programs. Males and females recalled sexual adverts equally, with no mediating effect of gender identity. Implications and limitations of the study are discussed. 相似文献

Since 2000, the reputation of health and safety in the United Kingdom has been tarnished, so much so that it has become the subject of both a media circus and a government inquiry. This not only threatens the worthy goals of health and safety, but also impacts upon the associated tool of risk assessment itself such that "risk assessment" is increasingly seen by the public at large as a term inviting ridicule, even abuse. The main thrust of the government's examination of health and safety has been its concern that safety requirements were placing a disproportionate burden on business. However, there is another source of discontent, which is public chagrin over the impact of injury control measures upon life beyond the conventional workplace, in particular upon the public spaces that people frequent in their leisure time and on the activities they engage in there. This article provides a perspective on this second dimension of the crisis in confidence. It describes how many U.K. agencies with responsibilities for a wide portfolio of public amenities ranging from the provision of play spaces for the young to the management of publicly accessible countryside, the maintenance of urban and rural trees, the stewardship of sites of cultural heritage, and the pursuit of outdoor educational activities have responded to some conflicts posed to their services by the new safety culture. It concludes with a discussion of implications for the management of public space and for risk assessment itself. 相似文献
