We investigated to what extent psychosocial work characteristics predict sickness absence in a cohort of 890 human service professionals (84% women), followed-up for 3 years. We measured 16 different psychosocial work characteristics at baseline and analysed their associations with number of sickness absence days at follow-up using multivariate Poisson regression. In addition, we computed a psychosocial work environment index, summarizing eight psychosocial scales. Participants with exposure to violence and threats, high emotional demands, high demands for hiding emotions, low influence at work, low meaning of work, low quality of management, and role conflicts had an increased number of sickness absence days at follow-up, after adjustment for numerous confounders. Adjusting for sickness absence history caused little change in most effect estimates. Scoring in the most adverse quartile of the psychosocial work environment index was associated with a 71% increase in sickness absence days. Improving the psychosocial work environment index and eliminating exposure to violence and threats would have prevented 32% of all sickness absence days in the study population. In particular we found that exposure to violence was a strong predictor of absence. This study shows that a wide range of psychosocial work characteristics contribute to sickness absence in human service workers. Improving the psychosocial work environment might help to reduce sickness absence in this population.  相似文献

Basing findings on data from the longitudinal programme Individual Development and Adaptation (IDA; n = 1383) it was found to be twice as common for girls to have been subjected to problematic upbringing conditions as for boys (here defined by experiencing major changes with regard to the child's caregivers; i.e. not just one parental divorce). This characterized 7.4% of the girls and 3.5% of the boys, a highly significant difference. A simple count of the number of parental transitions a child had been subjected to during upbringing also showed a sex difference in the same direction. As expected, girls with such disrupted upbringing showed adjustment problems during the school years, especially with regard to hyperactivity-related behaviours and conduct problems. The corresponding group of boys showed less pronounced adjustment problems. The generalizability of the results are discussed and tentative explanations presented for the sex differences that were found.  相似文献

The last twenty-five years have seen the emergence of a transnational gay/lesbian/bisexual/transgender (GLBT)/queer cultural movement unprecedented historically in its scope and openness. This interview with British art historian and critic Edward Lucie-Smith examines the role of gay male erotic art and film within that movement. Taking its start from the centrality of same-sex sexual orientation to the sense of gay identity and the importance of erotic art in validating that identity, it explores the historical, psychological, and social significance of a branch of visual art that until recent decades was not even acknowledged to exist, much less considered an appropriate subject of scholarly interest. By discussing gay male erotic art within a serious art-historical context, the article aims at providing a framework for examining the topic more systematically within the GLBT/queer studies domain.  相似文献

Abstract.  In observational studies treatment may be adapted to the patient's state during the course of time. These covariates may in turn also react on the treatment under study, and so on. This makes it hard to distinguish between treatment effect and selection bias. Structural nested models aim at estimating treatment effect in such complicated situations, even when treatment may change at any time. We show that structural nested models can often be calculated with standard software, by using standard models to predict treatment as a tool to estimate treatment effect. Robins ( Survival analysis, Volume 6 of Encyclopedia of Biostatistics , John Wiley and Sons, Chichester, 1998) conjectured this, but so far it was unproven. We use a partial likelihood approach to choose the estimators and tests as a subclass of the estimators and tests in Lok (math. ST/0410271 at http://arXiv.org , 2004). We show that this is the class of estimators and tests that can be calculated with standard software. The estimators are consistent and asymptotically normal, and have interesting asymptotic properties.  相似文献

《末路狂花》是一部典型的女权主义电影,它展示了两位原本符合传统男权理念中"安琪儿"形象的现代女性遭遇的无所不在的男权压迫和她们以"疯狂"的方式反抗男性歧视与凌辱的历程,暗示了"双性同体"的理想女性模式.  相似文献
