We conducted semistructured interviews with 38 participants in White racist Internet chat rooms, examining the extent to which people would, in this unique environment, advocate interracial violence in response to purported economic and cultural threats. Capitalizing on the anonymity and candor of chat room interactions, this study provides an unusual perspective on extremist attitudes. We experimentally manipulated the nature and proximity of the threats. Qualitative and quantitative analyses indicate that the respondents were most threatened by interracial marriage and, to a lesser extent, Blacks moving into White neighborhoods. In contrast, job competition posed by Blacks evoked very little advocacy of violence. The study affords an assessment of the advantages and limitations of Internet-based research with clandestine populations.  相似文献

The impact of work stressors and work-related resources on emotional exhaustion and depersonalization, as the two core factors of burnout, is investigated. According to the German Action Regulation Theory work stressors are conceptualized as regulation problems that lead to work stress in terms of additional effort (e.g. working longer hours), increased intensity of effort (e.g. working at a faster pace), and risky action (e.g. by neglecting safety rules). Consequently, an extended process model consisting of objective work stressors, work stress, emotional exhaustion and depersonalization is proposed. Nurses from three general hospitals (N=482) provided data for evaluating this model. Complete mediation of work stress and emotional exhaustion were analysed by hierarchical regression analysis. The overall model was tested by structural equation analysis in two steps; in the first step the basic model was analysed while in the second step the model was extended by autonomy as a work-related resource. The process model could be confirmed with respect to: (1) the mediating function of work stress and emotional exhaustion, and with regard to (2) the direct impact of autonomy as a work-related resource on work stressors but not on emotional exhaustion and depersonalization. Methodological considerations and implications for work design and burnout prevention are discussed.  相似文献

The Demand-Control model of occupational stress posits an interaction between job demands and job control predicting psychological strain, but previous research has found such an interaction only rarely or inconsistently. Such research, however, has often failed to measure either demands or strain faithfully to the model's constructs, or has simply failed to test for a statistical interaction. The present study corrected these shortcomings by going back to basics. Using a sample of 115 employees in a manufacturing company, it operationalized the variables more consistently with their original conceptualizations. However, when the hypothesized Demand-Control interaction was then tested, it still failed. Outcomes other than psychological strain (e.g. job dissatisfaction) were related negatively rather than positively to demands. This highlights the difference between psychological strain and dissatisfaction and casts doubt on models positing dissatisfaction as an intervening variable between stressors and strains.  相似文献

The origin and frequency of spontaneous mutations that occur with age in humans have been a topic of intense discussion. The mechanisms by which spontaneous mutations arise depend on the parental germ line in which a mutation occurs. In general, paternal mutations are more likely than maternal mutations to be base substitutions. This is likely due to the larger number of germ cell divisions in spermatogenesis than in oogenesis. Maternal mutations are more often chromosomal abnormalities. Advanced parental age seems to influence some mutations, although it is not a factor in the creation of others. In this review, we focus on patterns of paternal bias and age dependence of mutations in different genetic disorders, and the various mechanisms by which these mutations arise. We also discuss recent data on age and the frequency of these mutations in the human male germ line and the impact of these data on this field of research.  相似文献

In this article we examine changes in the proportion of older widowed and divorced women in England and Wales moving from 'independent' to two kinds of 'supported' household--supported private households and institutions--during the decades 1971-81 and 1981-91. Our main aim was to see whether observed increases in institutionalisation over this period were the result of a decreased propensity to move to the households of relatives. We used the ONS Longitudinal Study, a record linkage study including individual level data from the 1971, 1981 and 1991 censuses of England and Wales. A multinomial logit model was used to investigate the correlates of transitions from independent to supported private households versus institutions among elderly widowed and divorced women. While the overall rate of transitions to join either supported private households or institutions was largely the same in the two decades, the balance between the two shifted markedly in favour of transitions to institutions. In terms of the limited range of covariates it was possible to consider, owner-occupiers were significantly more likely than tenants to move to supported private households than to institutions.  相似文献
