Model averaging procedure for partially linear single-index models

This paper is concerned with model selection and model averaging procedures for partially linear single-index models. The profile least squares procedure is employed to estimate regression coefficients for the full model and submodels. We show that the estimators for submodels are asymptotically normal. Based on the asymptotic distribution of the estimators, we derive the focused information criterion (FIC), formulate the frequentist model average (FMA) estimators and construct proper confidence intervals for FMA estimators and FIC estimator, a special case of FMA estimators. Monte Carlo studies are performed to demonstrate the superiority of the proposed method over the full model, and over models chosen by AIC or BIC in terms of coverage probability and mean squared error. Our approach is further applied to real data from a male fertility study to explore potential factors related to sperm concentration and estimate the relationship between sperm concentration and monobutyl phthalate.     

Review of Self-exclusion from Gambling Venues as an Intervention for Problem Gambling

Self-exclusion programs are required to be provided by gambling operators in many international jurisdictions in an attempt to provide an option for those who have gambling problems to avoid further gambling. However, minimal robust and comprehensive research has been conducted to evaluate the effectiveness of self-exclusion programs. There is much scope for reform and greater cohesion between jurisdictions, particularly neighbouring jurisdictions that would offer greater protection to individuals and industry bodies. This review outlines the evidence surrounding existing self-exclusion strategies, the benefits and limitations of such programs, and provides potential recommendations for an effective intervention program. Research suggests that self-exclusion programs are under-utilised by problem gamblers and are not completely effective in preventing individuals from gambling in venues from which they have excluded, or on other forms. Nonetheless, self-report indicates that self-excluders generally experience benefits from programs, including decreased gambling and increased psychological wellbeing and overall functioning. There are many areas in which existing programs could be improved, such as providing more resources for excluded individuals and reducing barriers to program entry, and more research is needed. However, self-exclusion programs are an important component of any public health strategy that aims to minimise gambling-related harms and these should be based as far as possible on empirical evidence for effective program components.     

Does antenatal education affect labour and birth? A structured review of the literature

ObjectiveTo undertake a structured review of the literature to determine the effect of antenatal education on labour and birth, particularly normal birth.MethodOvid Medline, CINAHL, Cochrane and Web of Knowledge databases were searched to identify research articles published in English from 2000 to 2012, using specified search terms in a variety of combinations. All articles included in this structured review were assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).FindingsThe labour and birthing effects on women attending antenatal education may include less false labour admissions, more partner involvement, less anxiety but more labour interventions.ConclusionThis literature review has identified that antenatal education may have some positive effects on women's labour and birth including less false labour admissions, less anxiety and more partner involvement. There may also be some negative effects. Several studies found increased labour and birth interventions such as induction of labour and epidural use. There is contradictory evidence on the effect of antenatal education on mode of birth. More research is required to explore the impact of antenatal education on women's birthing outcomes.     

Predictors of father‐son communication about sexuality

Examining the factors that influence adolescents’ sexual behaviors is crucial for understanding why they often engage in risky sexual behaviors. Using social cognitive theory, we examined predictors of father‐son communication about sexuality. Fathers (N = 155) of adolescent sons completed a survey measuring 12 variables, including self‐efficacy and outcome expectations. We found that (a) son's pubertal development, father's sex‐based values, father's education, father's communication with his father, outcome expectations, and general communication accounted for 36% of the variance in information sharing communication and (b) son's pubertal development, outcome expectations, general communication, and father‐son contact accounted for 20% of the variance in values sharing communication. Study findings can aid professionals in designing guidelines and programs to promote father‐son general communication and sex‐based communication.     

Supervision in the helping professions a practical approach

Abstract

This article is based on an ethnographic study undertaken to explore whether eight people diagnosed with terminal cancer and their families drew on aspects of their cultural identities to make sense of their journey towards death, and if so, how. Ethnographic methods were supplemented by semistructured interviews. Most participants received medical treatments until close to death and invested much effort, time, and hope in these. Consequently, they made little sense of their palliative referrals. Instead, they accommodated the biomedical cultures of treatment-oriented services, thus delaying their own and their family's preparation for death. Only three participants appeared well prepared one month prior to death. An ecological perspective helped to explain the systemic factors involved in this prioritisation. The authors make recommendations for greater involvement of social workers in palliative care, and for more attention to supporting dying people and their families to make culturally meaningful decisions in the journey toward death.     

A framework for providing telecommuting as a reasonable accommodation: some considerations on a comparative case study

Telecommuting, whether full time, part time, or over short periods when the need arises, can be an important accommodation for employees with disabilities. Indeed, telecommuting may be the only form of accommodation that offers employees whose disabilities fluctuate a means to stay consistently and gainfully employed. This article describes one employer's experience in considering a request for telecommuting as a reasonable accommodation for a particular employee. Drawing on real-life examples, both positive and negative, this article provides a win/win framework for decision-making that can help employers evaluate the use of telecommuting as a possible accommodation and facilitates open and ongoing communication between employer and employee.     

Inflammatory effects and immune system correlates of rape

The purpose of this study was to evaluate the feasibility of measuring stress hormones and immunity following rape. The long-term goal is to evaluate the predictive value of stress-immune-inflammatory responses to later health outcomes. Fifteen women reporting rape were compared with 16 control participants. Serum stress hormones, proinflammatory cytokines, acute phase proteins, functional assays, and lymphocyte subsets were measured in blood samples. Women reporting rape had higher cytotoxic cells, lower B lymphocyte counts, higher proinflammatory biomarkers, and decreased lymphocyte proliferation compared to the control group. This finding suggests that rape produces activation of the innate immunity and suppression of some aspects of adaptive immunity. If these immune changes persist, they may contribute to the pathophysiology of long-term health sequelae by provoking chronic inflammation and decreased cellular immunocompetence.     

Integrating the older/special needs adoptive child into the family

This qualitative, grounded theory study investigated 11 families who reported having successfully integrated into their family unit at least one older/special needs adoptee. The theory that emerged through the constant comparative methodology consisted of two categories (Decision to Adopt and Adjustment) and a core category (Developing a Sense of Family). The two categories and core category comprised a process that was informed by the Family Narrative Paradigm and culminated in the successful integration of the child or children into the existing family unit. Parental perceptions that appeared to facilitate this process included: (a) finding strengths in the children overlooked by previous caregivers, (b) viewing behavior in context, (c) reframing negative behavior, and (d) attributing improvement in behavior to parenting efforts.
