Physical aggression and control in heterosexual relationships: the effect of sampling

This study investigated the proposition by Johnson (1995) that there are distinct patterns of physical aggression within relationships, characterized as common couple violence and patriarchal terrorism. The present samples comprised students (N = 113), women from a domestic violence refuge (N = 44), and male prisoners (N = 108). Participants completed measures of physical aggression, controlling behavior, fear of injuries, and injuries. Reports of these measures were entered into a Discriminant Function Analysis (DFA). With the exception of self-reported use of controlling behavior, the variables showed univariately significant differences between the groups. The DFA produced two significant functions which together correctly classified 75% of cases. These results support the view that there are distinct patterns of aggressive relationships corresponding to those identified by Johnson (1995).     

Integrated likelihoods in parametric survival models for highly clustered censored data

In studies that involve censored time-to-event data, stratification is frequently encountered due to different reasons, such as stratified sampling or model adjustment due to violation of model assumptions. Often, the main interest is not in the clustering variables, and the cluster-related parameters are treated as nuisance. When inference is about a parameter of interest in presence of many nuisance parameters, standard likelihood methods often perform very poorly and may lead to severe bias. This problem is particularly evident in models for clustered data with cluster-specific nuisance parameters, when the number of clusters is relatively high with respect to the within-cluster size. However, it is still unclear how the presence of censoring would affect this issue. We consider clustered failure time data with independent censoring, and propose frequentist inference based on an integrated likelihood. We then apply the proposed approach to a stratified Weibull model. Simulation studies show that appropriately defined integrated likelihoods provide very accurate inferential results in all circumstances, such as for highly clustered data or heavy censoring, even in extreme settings where standard likelihood procedures lead to strongly misleading results. We show that the proposed method performs generally as well as the frailty model, but it is superior when the frailty distribution is seriously misspecified. An application, which concerns treatments for a frequent disease in late-stage HIV-infected people, illustrates the proposed inferential method in Weibull regression models, and compares different inferential conclusions from alternative methods.     

Ethical Research Involving Children: Encouraging Reflexive Engagement in Research with Children and Young People

Research involving children raises complex and well‐documented ethical questions and challenges that extend far beyond the reach of formal review and governance systems, where these exist. However, researchers collectively have a wealth of knowledge and experience in applying universal ethical principles in diverse social, cultural and methodological settings, which offers much potential for understanding how ethical concerns are responded to in situ. Through extensive consultation and research, the Ethical Research Involving Children (ERIC) project, discussed in this article, has drawn on this collective knowledge in generating evidence‐based resources that highlight best practice while grounding ethical decision‐making in lived experience.     

Risky bodies in risky spaces: disabled people’s pursuit of outdoor leisure

Risk is used to deny disabled people access to many parts of mainstream life. Using qualitative data we explore disabled people’s views and experiences of outdoor recreation, bringing together ideas from two areas of sociology – disability studies and risk using the concepts of edgework and psycho-emotional disablism. Many people felt that the outdoors represented a risky environment. For some, risk was one of the main drivers for going out into the countryside; whilst for others, risk was a major cause of their reluctance to venture into the countryside. Engaging in risk both can disable and can challenge disablist views.     

Is the Relationship Between Pornography Consumption Frequency and Lower Sexual Satisfaction Curvilinear? Results From England and Germany

Several studies using different methods have found that pornography consumption is associated with lower sexual satisfaction. The language used by media-effects scholars in discussions of this association implies an expectation that lowered satisfaction is primarily due to frequent—but not infrequent—consumption. Actual analyses, however, have assumed linearity. Linear analyses presuppose that for each increase in the frequency of pornography consumption there is a correspondingly equivalent decrease in sexual satisfaction. The present brief report explored the possibility that the association is curvilinear. Survey data from two studies of heterosexual adults, one conducted in England and the other in Germany, were employed. Results were parallel in each country and were not moderated by gender. Quadratic analysis indicated a curvilinear relationship, in the form of a predominantly negative, concave downward curve. Simple slope analyses suggested that when the frequency of consumption reaches once a month, sexual satisfaction begins to decrease, and that the magnitude of the decrease becomes larger with each increase in the frequency of consumption. The observational nature of the data employed precludes any causal inferences. However, if an effects perspective was adopted, these results would suggest that low rates of pornography consumption have no impact on sexual satisfaction and that adverse effects initiate only after consumption reaches a certain frequency.

The Perspectives of Young Men and Their Teenage Partners on Maternity and Health Services During Pregnancy and Early Parenthood

This study discusses young couples’ interactions with maternity and health services paying particular attention to men’s perspectives. Findings are based on research conducted in Scotland with men (aged 16–25) and their teenage partners (aged 16–19). Most young men were very involved in their child’s life and provided support and care to their partner during pregnancy and in early parenthood. Men often felt excluded or judged when accessing services, although positive experiences were reported too. The study discusses ways in which maternity and health services can be better attuned to meet the needs of young couples and be inclusive of men.     

Children and safety in Australian policy: Implications for organisations and practitioners

Child safety is now a national policy priority in Australia. Extensive enquiries and reviews have escalated legislative and policy responses focused on developing, maintaining and monitoring “child safe” organisations. The recommendations of the Royal Commission into Institutional Responses to Child Sexual Abuse point to the importance of cultural conditions within organisations in supporting child safety and the need for responsive change in some organisations. Drawing on a recent policy analysis, undertaken as part of a larger Australian Research Council Discovery Project, this article examines how children and safety are constructed, within and across relevant state and federal government policies in Australia, and the implications of this. Distinctions are drawn between conceptualisations of children within the broader education policy context and two specific policy contexts in which children are considered particularly vulnerable to abuse – out‐of‐home care and disability. The findings indicate that policy discourses of “child safe” potentially foster different emphases and approaches in organisations. These have implications for the way children are positioned in relation to their safety, how their rights are recognised and implemented, and what is required to foster cultural conditions within organisations to best support children’s safety and wellbeing.
