Summary. This study investigates whether there was evidence of increasing risk of still-birth with increasing paternal exposure to ionizing radiation received during employment at the Sellafield nuclear installation before the child was conceived. A significant positive association is found between the total paternal preconceptional exposure to external ionizing radiation and the risk of still-birth (after adjustment for year of birth, social class, birth order and paternal age, odds ratio at 100 mSv 1.24 (95% confidence interval 1.04–1.45)). A summary of the principal scientific findings of this study has been published in the Lancet . This paper describes in detail the statistical methods that were used in the investigation and presents the results in full. 相似文献

Medical fraud and overservicing are estimated to cost the Australian community between $130 and $200 million per annum, a figure far greater than the national cost of burglary and almost the same as the total property loss from all conventional crime. An examination of the social antecedents of medical fraud and overservicing suggests that the predisposition of some doctors to engage in these practices occurs because of the following: (1) medical training and professional socialization that orientate student doctors away from altruistic health issues towards narrower self-interested professional concerns; (2) career expectations of a high pattern of material consumption that are often frustrated by an increasingly competitive medical market place; and (3) professional medical organizations that lobby for national health policies which reflect the mercenary self-interest of doctors rather than the health interest of the nation. 相似文献

The effects of sectoral shifts, measured by dispersion in the growth rates of employment or earning across industries or regions, on unemployment are tested in a specification controlling for the effects of other labor-market variables and shifts in the demographic composition of the labor force. Interindustry and geographical shifts in labor demand have significant unemployment effects, with adult males the group most strongly affected. The estimated equations imply that most of the fluctuation in unemployment over the period 1956-87 was been due to microeconomic causes rather than aggregate demand. 相似文献

The article contrasts two programmes aimed at improving thequality of life for older women in Australia. The CommunityOptions programme is a wellfunded Government initiative directedat personal care within the home. The Older Women's Networkis a grass-roots community development initiative. The articleexamines the relationship between control and resourcing interms of preventative and crisis care. 相似文献

Neighbourhood planning (NP) as enabled by the 2011 Localism Act in England has precipitated a considerable literature discussing its potential, limitations and likely shortcomings referenced against government rhetoric and the reporting of initial experiences of the process. This paper provides an overview of the current literature on neighbourhood planning and sets out how it has been received and practised across England drawing on empirical evidence. The extent of take-up and the experience of those involved in the first five years of neighbourhood planning is used to consider how community-led planning may be designed and used following operational principles of inclusivity, capacity-building and adding value. 相似文献

Van Valen's Red Queen hypothesis states that within a homogeneous taxonomic group the age is statistically independent of the rate of extinction. The case of the Red Queen hypothesis being addressed here is when the homogeneous taxonomic group is a group of similar species. Since Van Valen's work, various statistical approaches have been used to address the relationship between taxon age and the rate of extinction. We propose a general class of test statistics that can be used to test for the effect of age on the rate of extinction. These test statistics allow for a varying background rate of extinction and attempt to remove the effects of other covariates when assessing the effect of age on extinction. No model is assumed for the covariate effects. Instead we control for covariate effects by pairing or grouping together similar species. Simulations are used to compare the power of the statistics. We apply the test statistics to data on Foram extinctions and find that age has a positive effect on the rate of extinction. A derivation of the null distribution of one of the test statistics is provided in the supplementary material. 相似文献

The current economic climate demands more innovative approaches to increasing labor market participation for people with disabilities. Social entrepreneurship (SE) offers one alternative employment pathway. However, little is known about the broader factors influencing SE for people with disabilities. Using empirical data from focus groups comprised of social entrepreneurs with disabilities and interviews with key stakeholders working in the fields of policy, disability, and business, this research frames its analysis in the intersection of disability studies and entrepreneurship to explore which factors influence the potential for SE to provide equal participation opportunities for people with disabilities in the labor market. Findings suggest that further consideration of political–economic and socio-cultural factors is needed if we are to better understand the potential of SE for people with disabilities. 相似文献

Social work students in Britain receive feedback on a range of academic and practice issues as they progress through qualifying courses, however the way in which feedback differs to reflect the increasing complexity of learning as the course progresses is unclear. There is little, if any, guidance at a national level and the most widely known documents that provide information about the hierarchy of qualifications are the National Qualifications Frameworks (NQFs). Despite the widespread acceptance of NQFs there is little evidence supporting their use in professional areas such as social work. This study uses a documentary analysis to critique the Scottish Credit and Qualifications Framework (SCQF). The findings suggest that there are fundamental difficulties with the SCQF and its value in helping academics to better conceptualise feedback that reflects the increasing complexity of learning throughout the social work qualifying course. Whilst the SCQF is specific to a Scottish context, it is suggested that the inherent limitations and dominance of a neo-liberal ideology are common to other NQFs. It may be necessary to create the conditions where academics and students are able to discuss and debate the merits of NQFs and their implementation in social work qualifying courses. 相似文献
