Riemann sums for MCMC estimation and convergence monitoring

This paper develops an extension of the Riemann sum techniques of Philippe (J. Statist. Comput. Simul. 59: 295–314) in the setup of MCMC algorithms. It shows that these techniques apply equally well to the output of these algorithms, with similar speeds of convergence which improve upon the regular estimator. The restriction on the dimension associated with Riemann sums can furthermore be overcome by Rao–Blackwellization methods. This approach can also be used as a control variate technique in convergence assessment of MCMC algorithms, either by comparing the values of alternative versions of Riemann sums, which estimate the same quantity, or by using genuine control variate, that is, functions with known expectations, which are available in full generality for constants and scores.     

Gender equity and women's contraception use

Gender equity describes the distribution between men and women of social and material resources and decision‐making powers. Women's experiences of gender equity are likely to influence their contraceptive use. Multilevel analysis of two databases: the National Survey of Sexual Attitudes and Lifestyles from the United Kingdom and the United Nations' Fertility and Family Surveys, was undertaken to explore the association between gender equity measured at two spatial scales (small areas and countries) and women's contraception use. Results suggest that the spatial scale at which gender equity is considered is important. Gender equity was associated with contraception use at a local level, but not at the country level. Further, gender equity (at a local level) benefited women with less education in terms of increasing their likelihood of contraception use compared with more highly educated women. Results suggest gender equity is a potential pathway to reducing socio‐economic inequalities in health in developed settings.     

The Second Phase of US Welfare Reform, 2000–2006: Blaming the Poor Again?

This article examines the evolution of the programme Temporary Assistance for Needy Families (TANF) since 1996. In 1996, the transformation of Aid to Families with Dependent Children (AFDC) marked a watershed in American social policy. AFDC was the main US public assistance programme for single parents. By the mid-1990s, it was also the most unpopular social programme in the United States, which explained why Bill Clinton promised to 'end welfare as we know it' during his presidential campaign in 1996. TANF ended automatic individual entitlement to public assistance, established a five-year time limit for receiving cash assistance, and promoted a punitive approach towards welfare recipients, who were in theory increasingly required to work in exchange for benefits. This approach is known as the Work First Approach. Cash assistance was temporary, and granted as a favour to low-income mothers, who were required to comply with various behavioural requirements. TANF was hailed as a tremendous success on both sides of the political spectrum. This bipartisan consensus explains why the new Republican administration (G. W. Bush became President in January 2001) wanted to build upon the existing programme.     

Addressing the vision challenges of residents at a retirement community: collaborative research with a community partner

Staff members at a community retirement village were concerned about the demise of a support group for residents with vision loss, and requested help developing effective services for residents with vision challenges. This study explored past barriers to support group participation, as they were perceived by residents, family members, and employees. The community partner worked collaboratively with the researcher in all phases of the study. Questionnaires were designed to elicit demographic data, diagnosed vision problems, level of adjustment to vision loss, well-being, and motivation for attending institutional programs about vision challenges. Residents responded to standardized vision and depression scales; qualitative questions were posed to all 3 groups concerning motivations for resident participation in program activities. Results indicated that, although many residents had diagnosed vision conditions, they were, in general, coping well with vision loss and did not report depressive symptoms. Participants considered ongoing personal contact and follow-up, a group design that offered the choice of educational presentations and/or process discussions, and individualized assistance with practical challenges to be critical to an effective program. This case study, utilizing a collaborative research process, generated requests for expanded social work services and an increased valuing of the social work role.     

'Working at Disability': a qualitative study of the meaning of health and disability for women with physical impairments

Seven women with cerebral palsy and one woman with a spinal cord injury were interviewed about the meaning of health and disability in their lives. The most compelling feature of their narratives was the pressure to define their health by able-bodied standards. These women 'worked at' fitting their bodies and experiences into the limited societal understanding of a body. Paradoxically, the women seemed to come to a deeper personal understanding of disability and themselves through this work. The women's stories of health, impairment and disability, as told in the interviews, blended into rich chapters of their life stories.     

Criticism From Within An Interview With Kerrie James

Kerrie James is the Clinical Director at Relationships Australia (NSW). Having trained in family therapy in Canada in 1979, Kerrie came back to Australia and was employed by Relationships Australia (NSW), then the Marriage Guidance Council, to develop one of the first professional training programs in family therapy. Since then Kerrie has taught and supervised in family therapy both in Australia and overseas. Through her publications and presentations, Kerrie has made a significant contribution to the feminist debate within family therapy. Kerrie is currently completing a Masters in Womens Studies in which she is researching connections between the social constructions of gender and violence.     

Eyes on the Block: Measuring Urban Physical Disorder Through In-Person Observation

In this paper, we present results from measuring physical disorder in Los Angeles neighborhoods. Disorder measures came from structured observations conducted by trained field interviewers. We examine inter-rater reliability of disorder measures in depth. We assess the effects of observation conditions on the reliability of reporting. Finally, we examine the relationships between disorder, other indicators of neighborhood status, and selected individual outcomes.Our results indicate that there is considerable variation in the level of agreement among independent observations across items, although overall agreement is moderate to high. Durable indicators of disorder provide the most reliable measures of neighborhood conditions. Circumstances of observation have statistically significant effects on the observers’ perceived level of disorder. Physical disorder is significantly related to other indicators of neighborhood status, and to children’s reading and behavior development.This result suggests a need for further research into the effects of neighborhood disorder on children.     

Exploratory data structure comparisons: three new visual tools based on principal component analysis

Datasets are sometimes divided into distinct subsets, e.g. due to multi-center sampling, or to variations in instruments, questionnaire item ordering or mode of administration, and the data analyst then needs to assess whether a joint analysis is meaningful. The Principal Component Analysis-based Data Structure Comparisons (PCADSC) tools are three new non-parametric, visual diagnostic tools for investigating differences in structure for two subsets of a dataset through covariance matrix comparisons by use of principal component analysis. The PCADCS tools are demonstrated in a data example using European Social Survey data on psychological well-being in three countries, Denmark, Sweden, and Bulgaria. The data structures are found to be different in Denmark and Bulgaria, and thus a comparison of for example mean psychological well-being scores is not meaningful. However, when comparing Denmark and Sweden, very similar data structures, and thus comparable concepts of well-being, are found. Therefore, inter-country comparisons are warranted for these countries.     

Grandparents raising grandchildren: negotiating the complexities of role‐identity conflict

The purpose of this qualitative study was to better understand the experience of grandparents who are raising their grandchildren in New South Wales, Australia. In‐depth interviews were conducted with 34 grandparents and their narratives transcribed and studied using paradigmatic analysis to reveal common themes among the stories told. Identity theory further informed the discussion of these findings. Woven throughout the grandparent narratives is a story of paradox – of experience simultaneously made up of pain/pleasure, myth/reality, inclusion/exclusion, being deserving/undeserving, visible/invisible and voiced/silenced. The findings signal a significant role‐identity conflict for grandparents who are parenting grandchildren. This study points to the need for policy and practice that more closely reflects the complexity of experience associated with the grandparent‐as‐parent role.
