Gender,Racial, and Ethnic Disclosure in NIH K-Award Funded Diabetes and Obesity Clinical Trials∗

In 1993, the National Institutes of Health (NIH) passed The Revitalization Act (Subtitle B) which mandated that all NIH funded clinical trials have “appropriate representation” of minority and women subjects. Our aim was to evaluate the impact of the mandate by examining the reporting and inclusion of minority and female subjects into NIH K-Award funded clinical trials, addressing the minority predominant diagnoses of diabetes and clinical obesity. Using the CRISP search engine and PUBMED, we selected publications published by the National Institute on Aging (NIA) and National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) K-grant recipients during 1989–2004, associated with all the diabetes and obesity clinical trials. Studies were stratified into three timeline categories (1989–1993, pre-mandate; 1993–1996, post-mandate, and 1997–present, well past mandate) to evaluate trends in the recruiting of minorities and women before, during, and after the passing of the Revitalization Act. Of the 165 papers, only 37% disclosed race, a number that did not improve over time (p = .15), whereas 92% disclosed gender. Clinical trials that focused on females increased across the 3 timeframes (p < .001) for diabetes studies but not obesity studies. Overall, disclosure of race declined over the 3 timeframes whereas individually, the disclosure of African Americans improved.     

Sexual behaviour in aids‐related research: Reliability and validity of recall and diary measures

In order to assess the reliability and validity of two data collection instruments for measuring sexual practices in homosexual men, we administered a recall data collection instrument to 30 sexually active men, and a diary instrument to a subset of 19 participants. Each instrument covered a period of one month. For the recall instrument, the correlation coefficients between the test‐retest showed a good level of reliability for a number of infrequent sexual practices but was poor for frequent sexual practices. Correlation coefficients were calculated for sexual practices recorded in the first two and the second two weeks for both the recall and the diary. Generally, the level of agreement between the first and second two weeks for sexual practice data recorded in the diary was lower than the recall questionnaire. While the reliability of the recall method was found to be limited to certain sexual practices, it was concluded to be the most reliable and efficient method presently available for the collection of important high‐risk AIDS‐related sexual activities for a one‐month period.     

Evaluation of school‐based AIDS education curricula in San Francisco

Students in 3 middle (n=385) and 3 high schools (n=254) in the San Francisco Unified School District participated in the evaluation of an AIDS education curriculum. Classes within‐schools were designated as either intervention classes or nonintervention classes. Students in intervention classes received 3 class periods of AIDS instruction with a newly developed curriculum. Students in nonintervention classes did not receive any special AIDS instruction. All students completed a pretest and posttest AIDS knowledge and attitude survey. The results indicated that AIDS instruction classes demonstrated a significant knowledge‐advantage, as well as change in attitudes (e.g., reflecting greater tolerance for attending class with students who may have AIDS or HIV infection).     

The Passing of the Practice Teaching Award: History,Legacy, Prospects

This article reviews the origin, development and prospective demise of the Practice Teaching Award, as a prelude to considering the scope for reconfiguring practice teacher training and assessment on the GSCC landscape of social care codes of practice, qualifying programmes in social work and an integrated post‐qualifying framework. As a bridge from the past to the future, the article highlights a rich PTA ‘legacy’, identifying a particularly valuable ‘bequest’ in the ‘mainstreaming’ of portfolio assessment. Transcending the sphere of education and training as such, the reflective self‐assessment characteristic of effective portfolio construction is identified as a major contribution to the ‘professionalisation’ of social work practice as a whole.     

Social Work Students' Research-Related Anxiety and Self-Efficacy: Research Instructors' Perceptions and Teaching Innovations

The purpose of this mixed methods study was to examine social work research instructors' perceptions of research-related anxiety and research confidence among social work students, and teaching strategies to identify and manage anxiety. A national web-based survey of 186 BSW and MSW social work research instructors was conducted. Many BSW (70%) and MSW (61%) research instructors reported that they used specific activities or approaches to assess or impact upon student anxiety. Qualitative analysis results suggested a teaching model for social work research instructors designed to reduce students' research-related anxiety, including by enhancing their research confidence. Strategies that instructors can use include creating a supportive class climate, providing activities that are emotion-, cognitive-, and action-focused as well as the use of strategic timing. These findings can be used to guide social work research instructors' facilitation of students' attainment of research competencies and help further students' research–practice integration.

On the efficiency index of a graph

A graph \(G\) has an efficient dominating set \(D \subseteq V(G)\) if \(D\) dominates every vertex exactly once. In this paper we introduce the study of the family \({S_k}\) of graphs for which every \(G-S\) is efficiently dominatable for \(0 \le |S|\le k\). Assuming that \(G\) is efficiently dominatable, the efficiency index is the largest value k for which \(G\) is in \(S_k\). A graph \(G\) will be called super-efficient if every induced subgraph is efficiently dominatable. We give some characterizations for trees, grids, cylinders and torii to be super-efficient.     

“We're in this together”: Attachment insecurities,dyadic coping strategies,and relationship satisfaction in couples involved in medically assisted reproduction

Attachment is an important predictor of relationship satisfaction and attachment insecurities are a risk factor for couples under stress. Drawing from the Vulnerability–Stress–Adaptation model, we investigated whether dyadic coping strategies (DCS) would explain the links between attachment insecurities and relationship satisfaction in 97 couples involved in medically assisted reproduction (MAR). Path analyses revealed that for women and men, attachment insecurities (anxiety, avoidance) were associated with their own lower relationship satisfaction through their lower use of positive DCS. Attachment avoidance was also associated with participants' own lower relationship satisfaction through their own lower use of negative DCS. Men's attachment avoidance was also related to their partner's lower relationship satisfaction via their own and their partner's lower use of positive DCS. The findings suggest that promoting the use of positive DCS may be important to preserve relationship satisfaction in couples involved in MAR.
