Central Limit Theorem for ISE of Kernel Density Estimators in Censored Dependent Model

In some long-term studies, a series of dependent and possibly censored failure times may be observed. Suppose that the failure times have a common continuous distribution function F. A popular stochastic measure of the distance between the density function f of the failure times and its kernel estimate f _n is the integrated square error(ISE). In this article, we derive a central limit theorem for the integrated square error of the kernel density estimators under a censored dependent model.     

Nonparametric estimators for quantile density function under length-biased sampling

Abstract

In this article, the strong uniform consistency of two nonparametric estimators for the quantile density function is established under length-biased sampling. The rate of the strong approximation of the resulting processes of these estimators will be presented as well. A Monte Carlo simulation study is carried out to compare the proposed estimators with each other in terms of mean squared errors.     

Stress and Pressures in Mental Health Social Work: The Worker Speaks

Two-thirds of councils with social services responsibilities(CSSRs) took part in a UK survey of mental health social workers.A one in five sample of front line workers was drawn, and 237respondents completed a questionnaire and diary about theirwork context and content, and their attitudes to their work,their employer, mental health policy and the place of mentalhealth social work in modernized mental health services. Thequestions, that called for free-text responses, were completedin detail and at length. This paper reports the results of aqualitative analysis of these responses using NVIVO software.The paper is structured around the themes emerging from theanalysis: pressure of work; staffing matters; job satisfactionand well-being; recruitment and retention issues; and beingvalued. The conclusions are that the social workers value faceto face contact with service users, and that their commitmentto service users is an important factor in staff retention.The most unsatisfactory aspects of their work context arisefrom not feeling valued by their employers and wider society,and some of the most satisfactory from the support of colleaguesand supervisors. Without attention to these factors, recruitmentand retention problems will remain an unresolved issue.     

Sensual and Sexual Marital Contentment in Parents of Small Children—A Follow-Up Study When the First Child is Four Years Old

This follow-up study explored parents' (N = 452) intimate relationships when their firstborn child was 6 months old and then 4 years later. The measurement used was a modified version of the Dyadic Adjustment Scale, DAS. The present results show that most parents responding were content sensually at 6 months postpartum in 2002 and 4 years later, in 2006. More parents had changed from being sensually content in 2002 to discontent in 2006, than the contrary, however, and the sexual contentment remained low. The average sexual frequency was low both at 6 months and at 4 years for both parents with and without additional children. Experiencing tiredness as a hindrance to having sex was perceived as a greater problem among those parents without additional children. Prospective regression analyses indicated that sexuality was significantly related to both sensual and sexual contentment 4 years later. Sexuality was also one of the most significant covariates in the cross-sectional regression analysis for sensual contentment. Since sexuality plays a central role in partner well-being, it may be an important target for helping parents with small children.     

Evulvalution: The Portrayal of Women's External Genitalia and Physique across Time and the Current Barbie Doll Ideals

Media images of the female body commonly represent reigning appearance ideals of the era in which they are published. To date, limited documentation of the genital appearance ideals in mainstream media exists. Analysis 1 sought to describe genital appearance ideals (i.e., mons pubis and labia majora visibility, labia minora size and color, and pubic hair style) and general physique ideals (i.e., hip, waist, and bust size, height, weight, and body mass index [BMI]) across time based on 647 Playboy Magazine centerfolds published between 1953 and 2007. Analysis 2 focused exclusively on the genital appearance ideals embodied by models in 185 Playboy photographs published between 2007 and 2008. Taken together, results suggest the perpetuation of a “Barbie Doll” ideal characterized by a low BMI, narrow hips, a prominent bust, and hairless, undefined genitalia resembling those of a prepubescent female.     

Selection of Film Clips and Development of a Video for the Investigation of Sexual Decision Making among Men Who Have Sex with Men

Experimental research on sexual decision making is limited, despite the public health importance of such work. We describe formative work conducted in advance of an experimental study designed to evaluate the effects of alcohol intoxication and sexual arousal on risky sexual decision making among men who have sex with men. In Study 1, we describe the procedures for selecting and validating erotic film clips (to be used for the experimental manipulation of arousal). In Study 2, we describe the tailoring of two interactive role-play videos to be used to measure risk perception and communication skills in an analog risky sex situation. Together, these studies illustrate a method for creating experimental stimuli to investigate sexual decision making in a laboratory setting. Research using this approach will support experimental research that affords a stronger basis for drawing causal inferences regarding sexual decision making.     

Treatment Engagement Using Motivational Interviewing for Low-Income, Ethnically Diverse Mothers with Postpartum Depression

Postpartum depression (PPD) places women, and their children, at risk for many untoward outcomes including lack of responsivity, low self-efficacy, and insecure infant attachment. Especially at risk for untreated PPD are low-income, ethnically diverse mothers. Seeking and accepting treatment for depression may be impeded by the many psychological and social barriers that mothers may bring with them. Obstacles might include a lack of resources (e.g., lack of transportation or child care), stigma, distrust, and a lack of knowledge about stress and depression. To reduce these and other barriers to treatment, this paper points to the value of utilizing motivational interviewing techniques to engage and retain low-income, ethnically diverse women for treatment of PPD. Following a review of PPD and related barriers to treatment, a case study is presented with example dialogue. The suggestions for practice represent starting points for effective engagement of women in any number of treatments provided by social and health services settings. With federal mandates to screen for depression in many settings and to provide treatment, using motivational interviewing may be an effective prelude to treatment adherence.     

The effects of parental divorce on individuals’ commitment to same-sex relationships

Abstract

Research on the intergenerational transmission of divorce has demonstrated that individuals who come from divorced families have reduced commitment to the institution of marriage, which may translate to reduced commitment to one’s current relationship. We tested the association between two components of relationship commitment (dedication and constraint) and parental divorce in a sample of 251 adults in same-sex relationships. Results demonstrated that parental divorce was significantly associated with lower dedication commitment among women, but not men. Parental divorce was not associated with constraint commitment for either gender. These findings suggest that, consistent with research on individuals in different-sex relationships, women in same-sex relationships who come from divorced families may feel less dedicated to their own relationships, putting them at greater risk for relationship instability and divorce.     

Academic engagement and performance: Estimating the impact of out-of-home care for maltreated children

Using data from the National Survey of Child and Adolescent Well-being II, the authors examined whether being placed in foster care was associated with school engagement and performance. The authors used propensity score matching to compare children who had similar demographic characteristics, maltreatment histories, and prior levels of school engagement. Children who were in foster care at wave 2 were found to have higher levels of cognitive engagement in school compared to children who were maltreated but never removed from their homes. It is recommended that children who are maltreated but remain in their familial home receive additional intervention related to their educational engagement.     

Pregnancy risk among older youth transitioning out of foster care

Youth served in the foster care system have higher rates of pregnancy than general population youth; yet we have little information about risk and protective factors to target in order to prevent early pregnancy in this population. We assessed early pregnancy risk and protective factors known for general population adolescents for their relevance to youth in the foster care system. Using data from a longitudinal study of 325 older youth from the foster care system, we examined bivariate and multivariate relationships between these factors and pregnancy between ages 17 and 19 using logistic regression. Models examined the risk for early parenting separately by gender. The pregnancy rate increased by 300% between ages 17 and 19. At 19, 55% of females had been pregnant, while 23% of males had fathered a child. Although this study assessed multiple known factors, few were significant for this high risk group. Females who were not sexually active at age 17 were less likely to become pregnant, but those who reported using birth control were as likely to become pregnant as those who did not. Also, females with a history of arrest were more likely to have a pregnancy between 17 and 19. Males who left the foster care system before their 19th birthday were more likely to make someone pregnant. Youth from the foster care system are at exceptional risk of early pregnancy, regardless of their maltreatment history, religiosity, school connectedness, or academic achievement, particularly in the years between 17 and 19. This high risk group needs pregnancy prevention interventions and access to effective birth control.
