On estimating the covariance matrix of robust regression M-estimates

By analyzing a special class of regression problems we point out that previously suggested estimates of the covariance matrix of regression M-cstimatos are inadequate for certain design matrices. These results confirm the conclusions drawn in several Monte Cailo studies.     

Little Magazines and Translations

Abstract

Serials and the serials information chain have changed rapidly since the development of the electronic journal. Many recent developments are briefly described, including electronic resource management systems (ERMS) and functional requirements for bibliographic records (FRBR). The constantly changing nature of serials is compared to a psychological midlife crisis.     

Parenting and child-caretaking among black men who have sex with men and associated sexual and reproductive health factors: a brief report

Abstract

The purpose of this exploratory study was to examine the prevalence of parenting and child-caretaking among a sample of black men who have sex with men (MSM), as well as associations between parenting roles and sexual and reproductive health (SRH) factors. Parenting and SRH data were derived from a survey of 199 black MSM. Nearly half of the sample reported being a father or father-figure (44.4%), almost a third indicated serving as caretaker of a child (29.1%), and one in five have a biological child (20.1%). Over half of the sample reported at least one of these three parenting/child-caretaking roles (52.5%). Two significant differences were observed for sexual health variables: men with biological children were significantly more likely to report using condoms inconsistently (55.0% vs. 35.7%, p = .026) and engaging in transactional sex work (36.8% vs. 21.0%, p = .041). Given the observed prevalence, parenting and child-caretaking among black MSM warrant further inquiry as factors that may influence SRH outcomes and care utilization. Services and interventions tailored to black MSM should consider these men’s potential roles and responsibilities as parents and caretakers of children.     

Addressing common forms of child maltreatment: evidence‐informed interventions and gaps in current knowledge

This paper reviews interventions for preventing the occurrence and recurrence of major types of child maltreatment. We begin with an overview of the challenges of establishing evidence‐based interventions to prevent child abuse and neglect in many countries, and underscore the importance of this need with child maltreatment incidence rates in the USA, and how much each type and subtype contribute to child out‐of‐home placement. Next, we identify the well‐supported, supported and promising interventions for each child maltreatment type and subtype, according to their level of research evidence using an evidence‐based clearing house. The paper closes with a discussion of the implications for practice, evaluation, policy and agency management, including intervention knowledge gaps that showcase areas that need additional practice research.     

Energy Drinks,Weight Loss,and Disordered Eating Behaviors

Abstract

Objective: The present study examined energy drink consumption and relations with weight loss attempts and behaviors, body image, and eating disorders. Participants/Methods: This is a secondary analysis using data from 856 undergraduate students who completed the American College Health Association–National College Health Assessment II confidentially online during February 2012. Results: This study revealed that the majority reported lifetime consumption of energy drinks (68.4%) and a substantial minority (30.2%) reported past-30-day consumption. Chi-square and t test results suggest that consumption is associated with concerns about personal appearance, weight loss attempts, and disordered eating behaviors (eg, vomiting). Hierarchical logistic regressions revealed that after controlling for demographics, the relations between energy drink consumption and the act of trying to lose weight, the use of diet pills, and the use of vomiting/laxatives remained significant. Conclusions: The current findings suggest that energy drink consumption is associated with weight loss attempts, poor body image, and unhealthy weight loss behaviors. Future research should examine the prevalence of energy drink consumption for the purpose of weight loss.     

Responding to Self‐harm: A documentary Analysis of Agency Policy and Procedure

This paper reports on the findings of a documentary analysis of policies and procedures relating to self‐harm from a range of organisations working with young people in the UK. It identifies the extent to which policies and/or procedures relating to self‐harm are available for service providers and offers a wider understanding of the concepts of self‐harm and approaches to helping as incorporated into service guidance and delivery. It highlights the prevalence of self‐harming behaviours in a climate of stigma and the need to define appropriate and supportive agency responses from a trained staff that is both sensitive and individualised.     

The Postadoption Needs of Adoptive Parents of Children With Disabilities

Adoptions of children with disabilities are considered special needs, due to the higher level of support needed pre- and postadoption by families and children for adoptions to succeed. Despite this fact, very few studies examine the specific postadoption experiences of families with children with disabilities. Using secondary analysis of a national survey of adoptive parents, as well as interviews and a focus group with adoptive parents in one state, this study examines families’ with adopted children with disabilities challenges and unmet needs after adoption, as well as the postadoption needs and experiences of adoptive families with children with developmental and intellectual disabilities and adoptive families of children with emotional, behavioral, and mental health disabilities. Findings indicate that families with children with disabilities do report higher rates of challenges and barriers to service access, and that this is particularly true in families with adopted children with emotional, behavioral, and mental health disabilities. Implications for research and practice are discussed.     

Factors Influencing the Degree and Pattern of Parental Involvement in Play Therapy for Sexually Abused Children

Although much has been written about the role of therapists in children's recovery from child sexual abuse, relatively little attention has been paid to the role of nonoffending parents. This study investigated the work of a team of therapists who sometimes included such parents in therapy sessions with children. The study sought to understand what factors were influencing the degree and pattern of parental involvement and to understand what effect these patterns of parental involvement were having on the process and outcomes of therapy. The study successfully identified a range of factors influencing the patterns of parental involvement, but more research will be needed to understand the effect on outcomes.
