Limit theory for autoregressive-parameter estimates in an infinite-variance random walk

We consider the asymptotic behaviour of least-squares and M-estimates of the autoregressive parameter when the process is an infinite-variance random walk. It is shown that certain M -estimates converge faster than least-squares estimates and that they are also asymptotically normal.

What date/acquaintance rape victims tell others: a study of college student recipients of disclosure

The authors surveyed 828 college students and found that approximately one third (n = 282) of the respondents reported that one or more women had told them that they had been raped by their dates or acquaintances. The 282 respondents who knew 1 or more victims of date/acquaintance rape reported on a total of 396 victims. The number of victims identified by respondents ranged from 1 to 3 or more (1 = 73%; 2 = 19%, 3 = 5%, > or = 4 = 3%). Reactions to disclosure offered by these respondents were generally supportive of the victim. The respondents' reactions suggested that there is a continuing need to educate students about the incidence and risks associated with date/acquaintance rape and the possibility of disclosure, particularly by friends or dating partners, and brought out some possible helpful and some counterproductive reactions to such disclosures.     

Women's self‐presentation and the transition from classroom to workplace

Organizations place context‐specific appearance demands on women — demands that often echo wider inequalities, require adaptation of self‐presentation and impact on women's careers. Despite this, the effect of life and career stage transition on women's self‐presentation and embodied identities remains largely unexplored. Drawing on a qualitative study of young British women's body modification, this article examines what impact transitioning from education into the world of work has on women's self‐presentation and body modification regimes and their embodied identities. Body modification here refers to all methods women use to alter their physical body and appearance (e.g., invasive or non‐invasive; self‐administered or other‐administered; permanent or temporary), provided the intention of their use is primarily to alter the user's physical appearance. Expectations of transition, the impact of entering the workplace and of career establishment are considered as well as the significance of career stage and vulnerability for resistance and negotiation of organizational expectations. Transition of life stage is found to be a catalyst for self‐presentation change. The transition from education to work is identified as having a significant impact on body modification practices across workplaces.     

Patterns of positivity: Positive affect trajectories among infants of mothers with a history of depression

This study examined positive affect (PA) trajectories over the first year of life among infants of mothers with a history of depression (N = 191) as well as predictors (i.e., maternal prenatal and postpartum depression symptoms, maternal parenting behaviors) of those trajectories. Infant PA was observed in play and feeding tasks during laboratory visits at 3, 6, and 12 months of age; parenting behaviors were observed at 3 months. Mothers completed questionnaires regarding their symptoms of depression throughout the prenatal period and during the first 3 months postpartum. Growth curve analyses indicated that infant PA increased across time, and this finding replicated across both the play and feeding tasks, though increases slowed over time. Neither maternal prenatal nor postpartum depression symptoms predicted infants' PA trajectories, but mothers' PA, positive parenting, and disengaged parenting were associated with infant PA during the play task. Our finding that infant PA increased over the first year postpartum suggests PA trajectories among infants of mothers with a history of depression may be indices of resilience, despite risks associated with their mothers' history of depression. Furthermore, this study highlights parenting behaviors that may be important targets of prevention and early intervention efforts to bolster infant PA.     

Sing for the Moment: A Choral Ensemble for Persons with Dementia and Their Care Partners

Research suggests that people with Alzheimer’s disease and other dementias receive various benefits from singing. This article describes the Sing for the Moment Choir, an ensemble comprised of persons with Alzheimer’s disease or related dementias, and their care partners. The choir is sponsored by the greater Pennsylvania Chapter of the Alzheimer’s Association. As the world’s leading voluntary health organization in Alzheimer’s care, support, and research, the Alzheimer’s Association is committed to raising awareness of this fatal brain disease. The program mission statement is: “the Sing for the Moment Choir provides persons with Alzheimer’s disease and related dementia and their care partners an opportunity to socialize, connect and inspire others through singing.”     

The Gudaga Research Program: A Case Study in Undertaking Research with an Urban Aboriginal Community

This paper presents the Gudaga Research Program as a case study describing the practice principles used to implement a successful research partnership with an urban Aboriginal community in south-western Sydney. This is one of few papers that address research issues unique to working with urban Aboriginal communities, in which the Aboriginal culture of the community is not homogenous. The authors argue that the relationships between the researchers and key community members and research participants underpin the research success. Throughout, the authors show that ongoing processes to nurture and reaffirm these relationships are important and require ongoing investment. A proposed practice framework demonstrates the relationship between knowledge and understanding of Aboriginal history and culture, the underpinning values including trust, respect, and reciprocity, and shared skills and communication. Examples of how these were built into the research are provided. These are important skills that have application beyond the research process.     

Promoting Resilience Through Social Work Practice with Groups: Implications for the Practice and Field Curricula

The realities of contemporary social work practice often push social workers toward a deficit-focused orientation. The article begins with an overview of the major tenets of resiliency and adversarial growth theories and related research findings. We suggest that the group modality epitomizes the application of resiliency theory and adversarial growth to social work practice. A primary focus of this article is on articulating and illustrating the unique contribution group work makes for promoting client resilience. The article provides a theoretical and empirical framework that students, practitioners, and educators alike can use to identify, understand, and capitalize on client strengths through group work. Implications for social work education, specifically the practice and field curricula, are discussed.     

How to Describe It? Why the Term Coming Out Means Different Things in the United States and France

Drawing on 30 in‐depth interviews with U.S. and French lesbians, gay men, and bisexuals, we find important similarities in how U.S. and French respondents strategically managed the visibility of their sexual identities but differences in the vocabulary used to discuss those experiences. Specifically, all of the Americans used the expression coming out spontaneously while only five French respondents did so. Instead, French respondents typically rejected coming out in favor of other words or expressions. Rather than simple effects of speaking different languages, these differences stemmed from distinct connotations given to the same—widely diffused—expressions within each local context. Unlike their American peers, who saw the expression's origin in their own history and used in everyday lives, most French respondents resisted what they perceived to be an American cultural object imported by the French media. We also find evidence that the meaning of coming out is changing in both contexts such that in the future, the French and Americans may perceive and use it more similarly. This research contributes to our understanding of the intersection between language, meaning, and political context, within a cross‐national setting.     

Sexual Behavior Latent Classes Among Men Who Have Sex With Men: Associations With Sexually Transmitted Infections

Men who have sex with men (MSM) are at disproportionate risk of acquisition of sexually transmitted infections (STIs). We used latent class analysis (LCA) to examine patterns of sexual behavior among MSM and how those patterns are related to STIs. We examined patterns of sexual behavior using behavioral and clinical data from a cross-sectional study of 235 MSM who presented to an urban sexual health clinic for STI testing. Analyzed data were collected using a combination of interviewer- and self-administered surveys and electronic health records. We used LCA to identify underlying subgroups of men based on their sexual behavior, described the demographics of the latent classes, and examined the association between the latent classes and STI status. We identified three latent classes of sexual behavior: Unprotected Anal Intercourse (UAI) Only (67%), Partner Seekers (14%), and Multiple Behaviors (19%). Men in the Multiple Behaviors class had a 67% probability of being STI positive, followed by men in the UAI Only class (27%) and men in the Partner Seekers class (22%). Examining the intersection of a variety of sexual practices indicates particular subgroups of MSM have the highest probability of being STI positive.
