Monte Carlo Approximation of Bootstrap Variances

It is widely believed that the number of resamples required for bootstrap variance estimation is relatively small An argument based on the unconditional coefficient of variation of the Monte Carlo approximation, suggests that as few as 25 resamples will give reasonable results. In this article we argue that the number of resamples should, in fact, be determined by the conditional coefficient of variation, involving only resampling variability. Our conditional analysis is founded on a belief that Monte Carlo error should not be allowed to determine the conclusions of a statistical analysis and indicates that approximately 800 resamples are required for this purpose. The argument can be generalized to the multivariate setting and a simple formula is given for determining a lower bound on the number of resamples required to approximate an m-dimensional bootstrap variance-covariance matrix.     

Health Inequalities at the Heart of the Social Work Curriculum

Efforts to reduce the widening gap between the health and social well-being of people within and between countries have become an urgent priority for politicians and policymakers. The Rio Declaration called on governments worldwide to promote and strengthen universal access to social services and to work in partnership to promote health equity and foster more inclusive societies. This paper contributes to international debates about the role of social work in promoting social justice by reducing social and health inequalities. Despite clear commitments to promote good health, there is a notable absence of a social determinants of health perspective in international social work curricula standards. The current review of social work education in England presents a timely opportunity to integrate such a perspective in teaching and learning and to disseminate this more widely. Employing the concepts of downstream and upstream interventions, the first part of the paper examines the distinctiveness of the social work contribution to this global agenda. In the second part of the paper, we consider how the content of learning activities about health inequalities can be incorporated in international social work curricula, namely, human rights, using Gypsy and Traveller families as an exemplar, inter-professional education and international perspectives.     

Relationship Education for Stepcouples Reporting Relationship Instability—Evaluation of the Smart Steps: Embrace the Journey Curriculum

Smart Steps: Embrace the Journey is a research‐based educational curriculum for stepfamily couples (“stepcouples”). The curriculum is designed to build couple strengths while addressing the unique challenges of repartnering with a child or children from a previous relationship. This study evaluated the effectiveness of this curriculum with 151 individuals in relationally less stable stepcouple relationships who either engaged in the Smart Steps curriculum (n = 97) or were part of the comparison group (n = 54). This study represents methodological and conceptual advances in the study of stepfamily programs with the use of a comparison group, a racially and economically diverse sample, and a relationally at‐risk population. Results indicated that those who participated in Smart Steps reported significant increases in individual empowerment, couple quality, family harmony, and parenting efficacy while these measures were unchanged for those who did not receive the program. Implications for future research and for practitioners are provided.     

Changing structures: Necessary but not sufficient

Moves are afoot across the UK to change the mechanisms for managing local inter‐agency child protection policy and practice. This is being achieved through the development of Safeguarding Boards in England and Wales and guidance on Child Protection Committees that took effect from August 2005 in Scotland. Following our review of one Scottish Child Protection Committee (the SCPC), we are concerned that these changes focus almost exclusively on structure and pay scant attention to process and relationships. The study we undertook was an in‐depth evaluation of the functioning of the SCPC and used a range of qualitative methods. The main findings were that the size of the committee, its coverage of three local authority areas, and its patterns of working meant that some aspects of its work were highly developed and effective, such as the guidelines and multi‐agency training, while others, such as links with practice and the management of information systems, were poor. Considering these findings in the light of systems theory suggests that improving the effectiveness of child protection committees, and similar bodies, may need to be based on greater attention being paid to issues of authority, trust and negotiation among their members.
