Partnerships and participation seem to be the order of the day. Yet, for many community organisations, this way of ordering the social policy space is contradictory, creating practice tensions that increase the complexity of local service systems. Such changes impact community organisations in a politics that needs to be made visible if they are to be able to act in the interests of their members and service users. We therefore outline the social policy space currently constituted by four major discourses: neo‐liberalism, managerialism, new paternalism and network governance as they intersect and interact chaotically, reshaping participation and partnerships between government, community service organisations and local communities. We then examine how policy as a technology or set of mechanisms is discursively creating contradictions and practice tensions within which community organisations engage for social justice.  相似文献

This paper compares the ergonomic risk assessment of a task for the upper extremities as determined by Rapid Upper Extremity Assessment (RULA) and the Strain Index (SI). The ergonomic risk to the upper extremities of 244 automotive assembly plant tasks were evaluated using RULA and SI. The outcomes of each tool were compared for each task. Results from this study provide practical insight into the methods used in each tool. This study compared only the ergonomic risk outputs from each tool; it does not pursue the question of which tool best predicts injury. The kappa score was 0.11, indicating little agreement between the outputs of the two tools. This is supported by the lack of monotonicity with a gamma score of 0.1. These results indicate that the risk assessment outcome of these two ergonomic assessment tools for the upper extremities do not agree.  相似文献

Biomarkers such as DNA adducts have significant potential to improve quantitative risk assessment by characterizing individual differences in metabolism of genotoxins and DNA repair and accounting for some of the factors that could affect interindividual variation in cancer risk. Inherent uncertainty in laboratory measurements and within-person variability of DNA adduct levels over time are putatively unrelated to cancer risk and should be subtracted from observed variation to better estimate interindividual variability of response to carcinogen exposure. A total of 41 volunteers, both smokers and nonsmokers, were asked to provide a peripheral blood sample every 3 weeks for several months in order to specifically assess intraindividual variability of polycyclic aromatic hydrocarbon (PAH)-DNA adduct levels. The intraindividual variance in PAH-DNA adduct levels, together with measurement uncertainty (laboratory variability and unaccounted for differences in exposure), constituted roughly 30% of the overall variance. An estimated 70% of the total variance was contributed by interindividual variability and is probably representative of the true biologic variability of response to carcinogenic exposure in lymphocytes. The estimated interindividual variability in DNA damage after subtracting intraindividual variability and measurement uncertainty was 24-fold. Inter-individual variance was higher (52-fold) in persons who constitutively lack the Glutathione S-Transferase M1 (GSTM1) gene which is important in the detoxification pathway of PAH. Risk assessment models that do not consider the variability of susceptibility to DNA damage following carcinogen exposure may underestimate risks to the general population, especially for those people who are most vulnerable.  相似文献

We offer a theoretical perspective to provide insight into why people are ambivalent about sex and why cultures regulate sex and attach symbolic meaning to it. Building on terror management theory, we propose that sex is problematic for humankind in part because it reminds us of our creaturely mortal nature. Two experiments investigated the effects of reminding people of the similarity between humans and other animals on their reactions to the physical aspects of sex. In Study 1, priming human-animal similarities led to increased accessibility of death-related thoughts after thinking about the physical but not romantic aspects of sex. In Study 2, when participants were reminded of similarities between humans and other animals, mortality salience resulted in decreased attraction to the physical but not romantic aspects of sex. In each study, priming thoughts about how humans are distinct from animals eliminated the association between sex and death.  相似文献

A stochastic multitype model for the spread of an infectious disease in a community of heterogeneous individuals is analysed. In particular, estimates of R 0 (the basic reproduction number) and the critical vaccination coverage are derived, where estimation is based on final size data of an outbreak in the community. It is shown that these key parameters cannot be estimated consistently from data; only upper and lower bounds can be estimated. Confidence regions for the upper bounds are derived, thus giving conservative estimates of R 0 and the fractions necessary to vaccinate.  相似文献
