Multiple regression techniques were used to explore the nature of the relationships between age, tenure and absence in 2417 British local government workers drawn from three work groups. The data were collected from organizational records and included measures of both non-certified absence and medically certified absence. Linear and curvilinear associations among age, tenure and absence were examined. The possible moderating or mediating role of tenure in the relationship between age and absence was subsequently analysed. The data revealed linear relationships between age and absence that were negative for non-certified absence and positive for certified absence. In contrast, curvilinear relationships were found between tenure and absence that were U-shaped for noncertified absence and inverse U-shaped for certified absence. Tenure was found to moderate but not to mediate the relationship between age and absence. The implications of the results are discussed in the context of the changing age and career paths of the workforce, and of methodological issues in absence research.  相似文献

Newborns (N = 83) were presented with 3 conditions, each for 160 sec: tongue protrusion (TP), mouth opening (MO), and control (CO). In TP and MO, a female model alternated between demonstrating the gesture for 20 sec and presenting a passive, motionless face for 20 sec. In CO, she presented a passive face in both the “demonstration” and “passive” intervals. The participants' eyes were more widely open in the demonstration intervals of TP and MO than in the passive intervals, indicating that they were attending to the gestures. In TP, the participants produced more TP responses than MO responses, but in MO there was no effect, undermining the neonatal imitation hypothesis.  相似文献

Set within the framework of social disorganization theory, this article explores the relationship between social disorganization and parochial control. Specifically, this study investigates whether more disorganized communities support fewer religious institutions than less disorganized areas. It also examines the relationship between religious institutions and another type of community association: multi-issue, neighborhood-based organizations. Data are drawn from 1990 Census data, the 1991 Chicago telephone directory and local community organization directories. Findings support the idea that residential mobility and ethnic heterogeneity are negatively related to the prevalence of religious institutions whereas there is a curvilinear relationship between poverty and religious organizations. Finally, a strong relationship between the prevalence of religious institutions and the prevalence of multi-issue organizations is established.  相似文献

It has been advocated within corporate governance that institutional investors may discipline management in listed firms and thereby alleviate the free rider problem associated with dispersed ownership. This article tests this hypothesis using a sample of Danish listed firms during 1998–2001 determining, whether ownership by institutional investors impacts performance, measured by Tobin’s q. Using three stage least squares, it is shown that aggregate ownership by institutional investors does not influence firm performance. However, when decomposing the results, it is found that joint ownership by the largest two Danish institutional investors, has a significant negative impact firm performance. Ownership by banks and to a lesser extent insurance companies significantly influences firm performance positively. The results somehow challenge the conventional wisdom, arguing that the black box view of institutional investors should be abandon. Therefore it is suggested that a more careful analysis should be devoted to each institutional investors own legal environment.

Co‐production has risen to the fore of contemporary policymaking, with the intention of placing citizens at the heart of public service design and production. Although this may lead to more democratic and legitimate decision‐making, achieving “meaningful” co‐production can be difficult. In this qualitative study, we examine what constitutes meaningful co‐production, in particular asking whether there is a disconnect between the elite policy narrative that legitimizes co‐production and stakeholder experiences of this approach. Our research adopts a decentred approach to examine the different ways that actors understand and participate in co‐production, both as a methodology and as an interactive social practice. We conclude that a lack of synergy between local narratives may undermine the potential success of co‐production.  相似文献

Aquatic non‐native invasive species are commonly traded in the worldwide water garden and aquarium markets, and some of these species pose major threats to the economy, the environment, and human health. Understanding the potential suitable habitat for these species at a global scale and at regional scales can inform risk assessments and predict future potential establishment. Typically, global habitat suitability models are fit for freshwater species with only climate variables, which provides little information about suitable terrestrial conditions for aquatic species. Remotely sensed data including topography and land cover data have the potential to improve our understanding of suitable habitat for aquatic species. In this study, we fit species distribution models using five different model algorithms for three non‐native aquatic invasive species with bioclimatic, topographic, and remotely sensed covariates to evaluate potential suitable habitat beyond simple climate matches. The species examined included a frog (Xenopus laevis), toad (Bombina orientalis), and snail (Pomacea spp.). Using a unique modeling approach for each species including background point selection based on known established populations resulted in robust ensemble habitat suitability models. All models for all species had test area under the receiver operating characteristic curve values greater than 0.70 and percent correctly classified values greater than 0.65. Importantly, we employed multivariate environmental similarity surface maps to evaluate potential extrapolation beyond observed conditions when applying models globally. These global models provide necessary forecasts of where these aquatic invasive species have the potential for establishment outside their native range, a key component in risk analyses.  相似文献

Background

The increasing prevalence and adverse outcomes associated with opioid analgesia use in women of reproductive age have become a significant public health issue internationally, with use during pregnancy potentially affecting maternal and infant health outcomes.

Objective

This study aims to provide national estimates of chronic pain, pain severity and analgesia use in Australian women of reproductive age by pregnancy status.

Method

Data were obtained from the Australian Bureau of Statistics 2011–12 National Health Survey (n = 20,426). Weighting was applied to sample data to obtain population estimates. For this study data were analysed for pregnant (n = 166, N = 192,617) and non-pregnant women (n = 4710, N = 5,256,154) of reproductive age (15–49 years).

Results

Chronic or reoccurring pain was reported in 5.1% of pregnant women and 9.7% of non-pregnant women, and 0.7% and 2.6% of pregnant and non-pregnant women reported recent opioid analgesia use respectively. Moderate-to-very severe pain was more common in pregnant than non-pregnant women taking opioid analgesics, and no pain and very mild-to-mild pain in non-pregnant women.

Conclusion

Approximately 1 in 20 pregnant Australian women have chronic or reoccurring pain. Opioid analgesia was used by around 1% of Australian pregnant women during a two-week period, with use associated with moderate-to-very severe pain. Given that the safety of many analgesic medications in pregnancy remains unknown, pregnant women and health professionals require accurate, up-to-date information on the risks and benefits of analgesic use during pregnancy. Further evidence on the decision-making processes of pregnant women with pain should assist health professionals maximise outcomes for mothers and infants.  相似文献

Objective. The objective of the research reported in this article is to test four hypotheses concerning government funding among faith‐based social service coalitions: that it is positively related to size and organizational professionalism; positively related to attitudes toward government funding; positively related to social activism; and negatively related to organizational religiosity. Method. Our method is the application of OLS and probit analysis to data from a national survey of 656 such organizations. Results. Using three measures of government funding and 12 predictor variables, results are mixed in their support of the size and professionalization hypothesis and generally support the remaining hypotheses. These findings are replicated when we compare coalitions that had and had not applied for government funding. Conclusions. Our findings emphasize that greater religious expressiveness dissuades coalitions from both seeking and receiving government funding, but higher levels of social activism expedite both.  相似文献
