Grey seals in Britain are a conservation success, brought back from the brink of extinction by protection in the early 20th century. The public love them. Fishermen hate them. The resurgence of the "grey guzzlers" threatens their livelihood, they say. Len Thomas shows how Charles Darwin's ideas are used to determine seal numbers and population dynamics. Surprisingly, Darwin's theories have also influenced the statistical tools that are used. 相似文献

NGOs have, of late, found some of their traditional domains, such as provision of micro-credit and participatory development, coinciding with or being taken away by the state. How do they position themselves and retain relevance vis-a-vis the state in the changed scenario? Tracing the trajectory of interventions of a local NGO in Kerala, India, this article shows that NGOs exhibit ‘multiple identities’—selective collaboration, gap-filling and posing alternatives—in the process of engagement with the state. The ‘strategizing’ of such identities may hold the key to their relevance vis-a-vis the state. 相似文献

ABSTRACT Trauma-informed care (TIC) in social service organizations means that the organizations operate with the understanding that everyone involved has possibly experienced trauma in their lifetime. This qualitative study examined local service organizations’ usage of the 5 main principles of TIC: safety, trustworthiness, collaboration, empowerment, and choice (as developed by Fallot & Harris, 2006). Ten focus groups (n = 69) and 6 individual interviews (n = 6) with employees from administration through management were interviewed such that almost all facets of each agency were represented. The participants were asked about their agencies’ policies and practices for utilizing the 5 principles of TIC. The results suggest that the vast majority of organizations in this study implemented many of the principles of TIC with clients, though they had not labeled their practices as “trauma-informed.” However, although clients were receiving TIC, some of the principles were neglected as they pertain to staff, such as choice and empowerment. The findings of this study suggest that agencies are unaware of the relevance of TIC as it relates to staff. It is recommended that future research examine whether the use of TIC in agencies prevents “burnout,” high turnover rates, and vicarious traumatization of staff. 相似文献

The attempt to give children an effective voice in social work processes which can have substantial impact on their lives takes different forms in countries with varying professional cultures and legal frameworks. This paper reports on a study of children's participation in decision-making in care and protection services in Norway, which was carried out in conjunction with a project to support social work teams in enabling children to participate, using materials borrowed from England and Wales. The results showed that (a) taking an active part in decision-making did not correlate perfectly with (b) having an influence on the outcome. Cases were therefore classified as ‘participation’ or ‘non-participation’ using a combination of both the above criteria. Statistical analysis of the factors influencing children's participation enabled the proposition of a model which appeared to explain much of the variance. The results point to the inadequacy of equating social work conversation with children with effective participation in decision-making. 相似文献

We examine differences in the value of statistical life (VSL) across potential wage levels in panel data using quantile regressions
with intercept heterogeneity. Latent heterogeneity is econometrically important and affects the estimated VSL. Our findings
indicate that a reasonable average cost per expected life saved cut-off for health and safety regulations is 7 million to7 million to
8 million per life saved, but the VSL varies considerably across the labor force. Our results reconcile the previous discrepancies
between hedonic VSL estimates and the values implied by theories linked to the coefficient of relative risk aversion. Because the VSL varies elastically with income, regulatory agencies should regularly update the VSL used in benefit assessments,
increasing the VSL proportionally with changes in income over time. 相似文献

There has been considerable interest in studying the magnitude and type of inheritance of specific diseases. This is typically derived from family or twin studies, where the basic idea is to compare the correlation for different pairs that share different amount of genes. We here consider data from the Danish twin registry and discuss how to define heritability for cancer occurrence. The key point is that this should be done taking censoring as well as competing risks due to e.g. death into account. We describe the dependence between twins on the probability scale and show that various models can be used to achieve sensible estimates of the dependence within monozygotic and dizygotic twin pairs that may vary over time. These dependence measures can subsequently be decomposed into a genetic and environmental component using random effects models. We here present several novel models that in essence describe the association in terms of the concordance probability, i.e., the probability that both twins experience the event, in the competing risks setting. We also discuss how to deal with the left truncation present in the Nordic twin registries, due to sampling only of twin pairs where both twins are alive at the initiation of the registries. 相似文献

Preventing unsuitable people from working with children—the criminal justice and court services bill
Terry Thomas 《Child Abuse Review》2001,10(1):60-69
The continuing concern to safeguard children from abuse in schools, children's homes and similar settings has led to proposals to make it an offence for those with convictions against children to even apply for work with children. The Criminal Justice and Court Services Bill will introduce ‘disqualification orders’ for such offenders. The background development of this Bill is considered, together with the way the new orders will fit with existing criminal record check arrangements, current bans and the role of the forthcoming Criminal Records Bureau, which will tie all these systems together in a ‘one‐stop shop’.

The data set of 2,182 gay/bisexual men's month‐long sexual diaries collected by the United Kingdom Socio‐sexual Investigations of Gay Men and Aids (Project SIGMA) was used to analyse the extent to which acts of anal intercourse (AI) are distributed among gay men, using the Lorenz/Gini methodology for measuring concentration. Most individuals (60%) who engage in AI do so only once or twice a month, but there is a long tail of those who do it much more. In terms of the amount of AI acts, one tenth of the individuals are performing half of the acts of AI. The Gini coefficient of concentration is high (0.55). Factors most affecting rates and concentration of risk behaviour include relationship status, HIV sero‐status and concordant/discordant partner status. 相似文献
