Clustering objects on subsets of attributes (with discussion)

Summary.  A new procedure is proposed for clustering attribute value data. When used in conjunction with conventional distance-based clustering algorithms this procedure encourages those algorithms to detect automatically subgroups of objects that preferentially cluster on subsets of the attribute variables rather than on all of them simultaneously. The relevant attribute subsets for each individual cluster can be different and partially (or completely) overlap with those of other clusters. Enhancements for increasing sensitivity for detecting especially low cardinality groups clustering on a small subset of variables are discussed. Applications in different domains, including gene expression arrays, are presented.     

Young Men as Victims and Perpetrators of Violence in Northern Ireland: A Qualitative Analysis

This article explores issues of masculinity and violence in the lives of young men in disadvantaged areas in Northern Ireland. Qualitative data were collected in four focus groups, one group of young men from the Catholic community, one group of young men from the Protestant community, one group of community representatives, and one group of Young Offenders ( N = 28). Themes were extracted from the data using a grounded approach. Results indicate that social disadvantage is fundamental to experiences of violence and that young men understand the costs and benefits of a masculine identity that incorporates a capacity for violence. Discussion suggests that initiatives to reduce violent behavior should be compatible with socially and culturally acceptable constructions of masculinity.

The Bitter End: Emotions at a Movement's Conclusion

In Chile, not long after Pinochet stepped down, many shantytown women who had fought hard in the pro‐democracy movement felt very bitter. What explains this despondence, despite the positive outcome of their movement? This article addresses a question the social movement literature neglects: the question of how people feel when a movement ends. In doing so, it contributes to the literatures on movement decline and emotions in movements. I use ethnographic data from a year's fieldwork in Chile to suggest that at the end of a movement, even when it has succeeded in terms of achieving its goals, activists can feel disillusioned, disconnected, and abandoned.     

Siblings of individuals with first-episode psychosis: understanding their experiences and needs

The growth of early intervention in psychosis services (EIPS) has prompted needed research to provide a robust evidence base to underpin practice. The typical service model embraces key psychosocial interventions, including family interventions. A literature review revealed a number of relevant studies that recognized the role of siblings in families affected by severe mental illness or mental impairment, but little was found about the impact of first-episode psychosis on siblings. To address this apparent oversight, we conducted a study to gain an understanding of sibling experiences. Ten siblings (ages 16 to 30) with a brother or sister diagnosed with first-episode psychosis took part in individual semi-structured interviews. The key findings were grouped in regard to emotional impact, relationships in the family, and siblings' roles and coping patterns. The study also revealed that families are able to identify positive gains out of a fundamentally negative experience.     

U.S. Latinas' Knowledge and Attitudes toward Mammography: Meta-synthesis

Breast cancer is the leading cause of cancer death among Latinas in the United States. The primary purpose of this meta-synthesis was to integrate findings on qualitative studies related to Latinas' knowledge, attitudes, and perceptions regarding breast cancer and its prevention through mammography. After applying inclusion criteria, eleven studies were located. Results were organized around four areas of inquiry that cross-cut primary studies: 1) Latina participants' knowledge of breast cancer and its prevention; 2) barriers for regular mammography; 3) facilitators that encouraged such screening; and 4) recommendations on how to provide screening for Latina women.
