Relations between stressors and group perceptions: Main and mediating effects

Most orgnizations these days utilize groups for the performance of at least some tasks. There is therefore a need to examine the relationthip between job stressors and group functioning. Until now it has been proposed that employees who perceive high levels of stress in their jobs will have negative perceptions of the groups in which they work, in the form of reduced altruism and collective efficacy. They may also have higher levels of psychological strain. This study examined relations between job-related stressors and group perceptions (collective efficacy 3rd the prevalence of altruistic behaviour) in a sample of 2403 mililitary personnel, comprising 31 companies in two US Anny combat brigades. We also examined whether group perceptions mediated the relationship between stressors and both job satisfaction and subjective well-being. Results indicated that stressors were negatively associated with measures of group perceptions, and both job satisfiction and well-being. Furthermore, mediated regression analyses suggested that relations between interpersonal conflict and both job satitfaction and well-being were partially mediated by both group perception measures. These finding suggest that work-related stressors may negatively impact on group functioning, which may lead to employee strains. Implications of these finding are discussed, and suggestions are made for future research.     

Risk Policies in the United States: Definition and Characteristics Based on a Scoping Review of the Literature

The concept of “risk policy” is used with increasing frequency by decisionmakers, researchers, and the media. However, there is no precise, generally accepted definition of what is covered by policies in this area. Based on a scoping review of the literature published in key journals in the sector, we have identified the main characteristics of public risk policies drawn up and implemented in the United States. The sample comprised 21 articles published in six multidisciplinary journals between 2000 and 2010.     

A GENERALIZED EMERSON RECURRENCE RELATION

The Emerson (1968, Biometrics 24 , 695–701) recurrence relation has many important applications in statistics. However, the original derivation applied only to discrete distributions. In the following, a simple derivation is given that generalizes the Emerson recurrence relation to any distribution for which the necessary expectations exist. A modern application is outlined.     

Industrial injuries in British manufacturing industry

This paper begitis by cotisidering the effects of the business cycle upon the incidence of industrial accidents in British manufacturing industries, arguing that a generalized discussion of such cycles obscures important aspects of the political economy within individual cycles. In particular, the strength of the labour movement is related to the incidence of accidents at work. Since the trade unions are only one part of the tripartite system of the legal regulation of safety in British manufacturing industries, the paper goes on to consider the effects of recent material and ideological initiatives on the part of both the government and employers upon the ability of the Health and Safety Executive in general and the Factory Inspectorate in particular, to fulfil their role in this tripartite system of self-regulation. As a result of weakened trade unions and emasculated regulatory agencies, it is argued that there has been a virtual demise of this system of self-regulation. While the analysis outlined does not suggest that this demise is causal of the decline in safety performance across much of British manufacturing industry in the present decade, the paper does argue that the role of the law and its (non) implementation is not an insignificant factor in explaining this decline.     

Negative affectivity and gender as moderators of the relationship between work-related stressors and depressed mood at work

The present study provided further evidence on the role of negative affectivity (NA) and gender as moderators of stressor-strain relations. Based on theoretical and empirical research, it was hypothesized that the moderating effects of NA would moderate the relationship between stressors (role ambiguity, workload, role conflict and interpersonal conflict) and work-related depression. Questionnaires were returned form 442 subjects of whom 74% were recruited from external degree courses and the rest were full-time employees. Results revealed significant three-way interactions for two of the four stressors (workload and role ambiguity) in predicting work-related depression. NA moderated the relationship between these stressors and work-related depression for females but not for males. These effects were modest, however. No significant interactions were found for role conflict and interpersonal conflict. The implications of these results are discssed.
