The paper reviews public discourses and research on the safeguarding of other people’s children by adults at the neighbourhood level. There is much empirical evidence pointing to the existence of thriving informal communities of support and informal childcare for parents across the social classes. There appears to be less empirical evidence related to intervening with children and young people who may be at risk. Nonetheless, the limited evidence suggests that many neighbours, acquaintances and strangers do intervene, or say that they would. The paper concludes by considering the potential negative consequences of promoting the notion that safeguarding children is ‘everybody’s business’.  相似文献

Summary.  The paper provides a space–time process model for total wet mercury deposition. Key methodological features that are introduced include direct modelling of deposition rather than of expected deposition, the utilization of precipitation information (there is no deposition without precipitation) without having to construct a precipitation model and the handling of point masses at 0 in the distributions of both precipitation and deposition. The result is a specification that enables spatial interpolation and temporal prediction of deposition as well as aggregation in space or time to see patterns and trends in deposition. We use weekly deposition monitoring data from the National Atmospheric Deposition Program–Mercury Deposition Network for 2003 restricted to the eastern USA and Canada. Our spatiotemporal hierarchical model allows us to interpolate to arbitrary locations and, hence, to an arbitrary grid, enabling weekly deposition surfaces (with associated uncertainties) for this region. It also allows us to aggregate weekly depositions at coarser, quarterly and annual, temporal levels.  相似文献

Hahn (1977) suggested a procedure for constructing prediction intervals for the difference between the means of two future samples from normal populations having equal variance, based on past samples selected from both populations. In this paper, we extend Hahn's work by constructing simultaneous prediction intervals for all pairwise differences among the means of k ≥ 2 future samples from normal populations with equal variances, using past samples taken from each of the k populations. For K = 2, this generalization reduces to Hahn's special case. These prediction intervals may be used when one has sampled the performance of several products and wishes to simultaneously as- sess the differences in future sample mean performance of these products with a predetermined overall coverage probability. The use of the new procedure is demonstrated with a numerical example.  相似文献

College students may engage in risky sexual behaviors, such as inconsistent condom use, which increase their risk of sexually transmitted infections. This study examined the association between six condom influence strategies (CIS) and reported condom use among a diverse group of college students. Differences in CIS and condom use were examined by gender, race or ethnicity, and relationship status (casual, monogamous, or no current relationship). The study also used a cluster analysis to investigate how the CIS were used relative to one another, and how patterns of CIS use were related to condom use. Results showed interesting differences in CIS use by gender, race or ethnicity, and relationship status. Four patterns of CIS usage emerged, and results suggested that using all CIS frequently and using more assertive CIS may be particularly important for increased condom use. Men reported more condom use than women overall, but results indicated that using CIS were especially vital for increasing condom use for women. Surprisingly, there were no differences in condom use found for race or ethnicity and relationship type. Programs aimed at increasing students' condom use could benefit from promoting and practicing CIS, and recognizing potential differences among demographic groups.  相似文献

Summary This paper is concerned with a relatively unresearched areaof child protection practice: the comprehensive assessment.The study comprises qualitative research of social workers conductingthese assessments. Sixteen assessments are analysed in detail.It is noted that these assessments, like many other in-depthsocial work assessments, are mainly based on verbal interactions.Some of the core evidence cited by social workers as formingthe basis of their assessment decisions is based on verbal interactionbetween social workers and parents. Such verbal interactionsare viewed as being inextricably intertwined with the socialworker-client relationship. A particular aspect of the relationship,the ability to agree a plausible explanation for the familysituation, is highlighted as particularly important in determiningthe outcome of the assessment. The possible implications ofthese findings for assessment practices are outlined.  相似文献

Three agency-based studies explored the associations of traumatic child histories, as well as their developmental, health and behavioral problems with foster care challenges such as placement instability. The findings represent the convergent perspectives of child welfare workers and foster parents in small cities in Ontario. Alone and in aggregate, child and familial traumas and problems were very strong predictors of various foster care challenges. Foster parent training and other support needs are discussed.  相似文献

New member states will join the EMU in the coming years. Setting the central parity at which they will join has been and will be a challenging task, as there is a considerable amount of uncertainty, both from a theoretical and an empirical perspective, surrounding the determination of the optimal exchange rate. Given the probable difficulty in evaluating the equilibrium rate it is thus advisable to focus on the effects of a misalignment of the entry rate for the economy, as it has implications for countries’ real and nominal convergence. An overvalued exchange rate would have an adverse impact on a country's competitiveness and its growth, while an undervalued currency would contribute to an overheating of the economy and an excessive inflation. The objective of this paper is to better understand the role of the entry rates for short run inflation and GDP developments and their implications for the inflation criterion and the real convergence process. Having estimated equilibrium exchange rates for eight out of ten countries that entered the EU in May 2004: Czech Republic, Estonia, Hungary, Lithuania, Latvia, Poland, Slovenia and Slovakia we conduct simulations showing what their adjustments to equilibrium would be if their entry rates deviated from the optimal ones.  相似文献

Many nonprofit boards have undertaken board development activities, yet there has been little empirical evidence of the impact on board performance. This article reports findings from organizations: ten participated in developmental interventions, and fourteen received no interventions but served as matched comparisons. The experimental group showed significant improvements in board performance, and the comparison group did not. Lessons from the study include a number of practical steps boards can take to reorganize governance procedures and structures to enhance board effectiveness.  相似文献

This agency-based study explored the preventive impact of a multi-method intervention program for children in care who had been sexually abused. Participants were Aboriginal children of the Stól:lö Nation in British Columbia, Canada. It suggested that such programs offered in child welfare contexts could actually prevent many mental health and behavioral problems that otherwise would be more prevalently experienced by such traumatized children in care.  相似文献
