Farming is one of the most hazardous occupations in terms of the incidence and seriousness of accidental injuries. Research with other occupational groups has drawn attention to the role of psychosocial factors and stress. Such research needs to be extended to agriculture. Since stress may be a problem faced by farmers, there is a particular need to investigate the associations between farm accidents and work stressors and stress reactions. Using multivariate logistic regression analyses, this study aimed to uncover the best psychosocial predictors of injury, while controlling for exposure-related confounders. From a randomly selected sample of 794 farms, 10% of all farms in Ringkoebing County, Denmark, 393 farmers completed completed weekly accident registration over 12 months. The study sample consisted of 310 farmers who also completed questionnaires on psychosocial factors. Results indicated that farm stressors (including perceived economic problems), stress symptoms, and safety behaviour were predictors of occupational farm accidents. Higher levels of stressors and stress symptoms and poor safety behaviour were all associated with an elevated risk of injury. In the case of stress symptoms, the relation with accidents occurred via an interaction with safety behaviour. The combination of high levels of stress symptoms and poor safety behaviour was associated with a particularly high accident risk.  相似文献

The Scandinavian countries are part of the same legal tradition. No Scandinavian country has any written statute on non-profit associations. Their association law is flexible, common-sensical and easy to comply with. To obtain subsidies, the associations may have to submit to regulations regarding organisational structures (open membership and one person, one vote). The law on foundations is more formalised, and the foundations are subject to considerably more control and scrutiny. Scandinavian NPOs are usually exempt from income tax, but do not to any great extent benefit from deductibility for donations. They are subject to payroll tax, and usually to value added tax. The Scandinavian taxation policies may make the NPOs economically dependent upon the government, and subject to regulation through ‘subsidy law’.  相似文献

The population growth rate of the European dipper has been shown to decrease with winter temperature and population size. We examine here the demographic mechanism for this effect by analysing how these factors affect the survival rate. Using more than 20 years of capture-mark-recapture data (1974-1997) based on more than 4000 marked individuals, we perform analyses using open capture-mark-recapture models. This allowed us to estimate the annual apparent survival rates (probability of surviving and staying on the study site from one year to the next one) and the recapture probabilities. We partitioned the variance of the apparent survival rates into sampling variance and process variance using random effects models, and investigated which variables best accounted for temporal process variation. Adult males and females had similar apparent survival rates, with an average of 0.52 and a coefficient of variation of 40%. Chick apparent survival was lower, averaging 0.06 with a coefficient of variation of 42%. Eighty percent of the variance in apparent survival rates was explained by winter temperature and population size for adults and 48% by winter temperature for chicks. The process variance outweighed the sampling variance both for chick and adult survival rates, which explained that shrunk estimates obtained under random effects models were close to MLE estimates. A large proportion of the annual variation in the apparent survival rate of chicks appears to be explained by inter-year differences in dispersal rates.  相似文献

Abstract. In this paper, we study the detailed distributional properties of integrated non-Gaussian Ornstein–Uhlenbeck (intOU) processes. Both exact and approximate results are given. We emphasize the study of the tail behaviour of the intOU process. Our results have many potential applications in financial economics, as OU processes are used as models of instantaneous variance in stochastic volatility (SV) models. In this case, an intOU process can be regarded as a model of integrated variance. Hence, the tail behaviour of the intOU process will determine the tail behaviour of returns generated by SV models.  相似文献

Under current law Australia appears to be a tax haven for certain non-governmental institutions. Millions of ordinary business income may go untaxed and the deductibility for donations is unlimited – both are very generous tax measures in an international context. The basic problems of most Australian non-profit organisations are not taxation; it is their non-profit status and lack of funds. Anybody interested in the non-governmental sector should be willing to face the question: What is an equitable tax treatment? The short-term tactic of ducking the question may not be the best or most beneficial long-term strategy.  相似文献

This paper reports on a case study within an engineering consultancy firm, where engineering designers and ergonomists were working together on the design of a new hospital sterile processing plant. The objective of the paper is to gain a better understanding of the premises for integrating ergonomics into engineering design processes and how different factors either promote or limit the integration. Based on a grounded theory approach a model illustrating these factors is developed and different hypotheses about how these factors either promote and/or limit the integration of ergonomics into design processes is presented along with the model.  相似文献

The aim of this paper is to discuss the use of intermediary objects in the workspace design process of offshore accommodations module. The integration of ergonomics in the design process can lead to better work conditions, more effectiveness in the work process and less health and safety issues. Moreover, it is more efficient in terms of cost if ergonomics is considered from the initial phases of the project, as the potential costs of the redesign, the possible losses and the down-time in the operation of the platform would be more increased. The goal, then, is to discuss the integration of ergonomics and users involvement in the design process of accommodations modules, focusing on the transfer of information from reference situations by the use of intermediary objects during the process. In this paper we will present two tools developed to be used as intermediary object(s) aiming at transferring the experience from the use to the design in the specific field of offshore accommodations module.  相似文献

Multidisciplinary collaboration is central to modern social welfare organizations, yet knowledge about the organizational context of collaboration is scarce. The study objective was to establish multidisciplinary collaboration by designing an organizational field study. The aim of this article is to explore managerial roles and perspectives during an organizational process of developing multidisciplinary collaboration. Eighteen management meetings, held during a two-year period, are analysed. The analysis reveals that the management gradually grasps the complexity of multidisciplinary collaboration; negotiations on the concept are ongoing while their point of view changes from distant to involved. The management takes leadership towards multidisciplinary collaboration through a series of legitimacy-related negotiations, illustrating the organizational and managerial contexts of multidisciplinary collaboration as well as introducing it as a new type of managerial task.  相似文献
