How parents manage the risk of child sexual abuse: a grounded theory

The aim of this study is to understand how parents manage the risk of child sexual abuse, including prevention as well as early intervention and detection strategies. Using a social constructivist theoretical foundation and grounded theory methods, qualitative in-depth interviews were conducted with Australian parents between 2006 and 2008. Based on the data, a balance theory was developed, which explains how parents attempt to balance the type of information given to children in order to protect their children from sexual abuse without scaring them as well as how parents manage sexual boundary crossing incidents experienced by their children in the context of complex social relationships. Implications for prevention programs as well as reporting of child sexual abuse are discussed.

Perceptions of credibility of sexual abuse victims across generations

The success of prosecutions of perpetrators of sexual abuse often depends substantially upon the perceived credibility of the victim witness. However, perceptions of credibility may vary by generation of the observer, and the constitution of juries may therefore lead to bias. In this study we examined whether perceptions of credibility of female victims of sexual abuse varied across generation Y, generation X, "baby boomers", and "builders". One hundred and twenty-eight jury-eligible members of the community from each generation (N=512) responded to ten questions assessing the perceived believability, competence, trustworthiness, demeanour and sexual naiveté of females providing testimony related to alleged sexual abuse. Although consistent between-generation differences were not found for all questions, or all four groups of generational cohorts, in instances where significant differences were found, it was consistently the older generation groups (builders and baby boomers) that attributed less credibility to the victim than the younger generation groups (generation Y and generation X). The implications of these findings are discussed.

Changing dominance of key plant species across a Mediterranean climate region: implications for fuel types and future fire regimes

Herbaceous and woody plants represent different fuel types in flammable ecosystems, due to contrasting patterns of growth and flammability in response to productivity (moisture availability). However, other factors, such as soil type, fire regimes and competitive interactions may also influence the relative composition of herbaceous and woody plants within a community. The Mediterranean climate region of south eastern Australia is transitional between two contrasting fuel systems; herbaceous dominated in the dry north, versus woody plant dominated shrublands in the relatively moist south. Across the rainfall gradient of the region, there are confounded changes in dominant soil types and fire frequency. We used model-subset selection using Akaike's Information Criterion to examine potential driving mechanisms of community compositional change from herbaceous (e.g. Triodia scariosa, Austrostipa sp.) to woody plants (e.g. Beyeria opaca, Leptospermum coriaceum, Acacia ligulata) by measuring relative cover across combinations of rainfall, time since the last fire (TSF) and soil type. We examined the relative influence of environmental versus competitive interactions on determining the cover of perennial hummock grass, T. scariosa, and co-occurring woody shrubs. Rainfall and soil types, rather than competition, were the over-arching determinants of the relative cover of grasses and shrubs. Given the sensitivity to rainfall, our results indicate there is strong potential for the nature of fuel, flammability and fire regimes to be altered in the future via climate change in this region.

Explanations for the United States of America's dominance in basketball at the Beijing Olympic Games (2008)

Anecdotally, the fast pace at which the USA men's basketball team played at the 2008 Olympics was the main reason for their dominance, although there is no way of quantifying what a fast pace is or how it contributed to point differentials. The aim of this study was to examine the game-related statistics that discriminate between fast- and slow-paced games, as well as to identify key performance factors relating to point differentials. We analysed game-related statistics for each quarter of the eight games played by the USA using a k-means cluster analysis to classify game pace using ball possessions per game quarter. We then tested for differences in game statistics between slow- and fast-paced game quarters using analysis of variance and discriminant analysis. How differences in game-related statistics affected point differentials was examined using linear regression. The largest structure coefficient between game paces for the USA was for recovered balls (0.33, < 0.001). The biggest contributors to the point differences in games were recovered balls (16.9, P < 0.001) and field goals (22.2, P < 0.001). We conclude that when the USA play a fast-paced game, they are able to recover more balls from opponents that they then turn into effective field-goal shooting.

Identifying the characteristics of child sexual abuse cases that exit the criminal justice system before the forensic interview

Most child sexual abuse cases do not result in conviction; rather, they result in attrition at an earlier point in the system. Although research has looked at case characteristics associated with attrition at later stages of the system (i.e. the laying of charges and prosecution stages), to date, no research has studied the case characteristics associated with attrition as soon as a report has been made to authorities. The aim of this study was to determine the case characteristics (child complainant, suspect and additional case characteristics) associated with attrition when a case first enters the criminal justice system before a forensic interview is conducted. All child sexual abuse incidents reported to police in one jurisdiction of Australia in 2011 were examined. Three case characteristics were found to predict attrition: previous disclosure, abuse frequency and the child complainant’s age. Specifically, cases were more likely to result in attrition when the child had not previously disclosed the abuse to an adult, the abuse was a single incident rather than repeated, and a curvilinear relationship was found for child age. Cases involving children aged 7–12 years were less likely to result in attrition than cases involving younger (0–6 years) and older (13–15 years) children. This information should assist professionals and researchers in developing interventions to reduce the attrition when necessary during this early stage of the criminal justice system.

Investigative Interviewing of Aboriginal children in cases of suspected sexual abuse

This study examined the investigative interviewing of Australian Aboriginal children in cases of alleged sexual abuse, with a focus on three commonly included components of interview protocols: ground rules, practice narrative, and substantive phase. Analysis of 70 field transcripts revealed that the overall delivery and practice of ground rules at the beginning of the interview was positively associated with the spontaneous usage of rules in children's narratives of abuse. When specifically examining the "don't know" rule, however, only practice had an effect of children's usage of the rule (as opposed to simple delivery or no delivery at all). Children spoke more words overall, and interviewers used more open-ended prompts during the substantive phase when the interviews contained a practice narrative. Children most often disclosed sexual abuse in response to an open-ended prompt; however, they produced the most words in response to suggestive prompts. This article concludes with a discussion of the effectiveness of ground rules, practice narratives, and questioning with Aboriginal children.

Identifying the characteristics of child sexual abuse cases associated with the child or child's parents withdrawing the complaint

Most child sexual abuse cases do not result in a full trial or guilty plea; rather, case attrition occurs at earlier stages of the criminal justice system. One reason for the attrition of these cases is the withdrawal of complaints, by children or their caregivers. The aim of the current study was to determine the case characteristics associated with complaint withdrawal in child sexual abuse cases by the child or his or her parents once a report has been made to authorities. All child sexual abuse incidents reported to authorities in one jurisdiction of Australia in 2011 were analyzed (N=659). A multinomial logistic regression was used to predict the following case outcomes: (1) withdrawn by the child or his or her parents, (2) exited for other reasons (e.g., the alleged offender was not identified, the child refused to be interviewed), and (3) resulted in a charge. Five predictors significantly added to the prediction of case outcome: child age, suspect gender, suspect age, child-suspect relationship, and abuse frequency. These results should contribute to the design of interventions in order to reduce complaint withdrawals if these withdrawals are not in the child's best interests.

Pareto Dominance of Deferred Acceptance through Early Decision

An early decision market is governed by rules that allow each student to apply to (at most) one college and require the student to attend this college if admitted. This market is ubiquitous in college admissions in the United States. We model this market as an extensive-form game of perfect information and study a refinement of subgame perfect equilibrium (SPE) that induces undominated Nash equilibria in every subgame (SPUE). Our main result shows that this game can be used to define a decentralized matching mechanism that weakly Pareto dominates student-proposing deferred acceptance.

When she refuses to settle: reading adolescent female sexuality and sexual abuse in the poetry of Genna Gardini and Kate Lilley

This essay compares the representations of adolescent sexual abuse and female sexuality in the poetry of South African poet Genna Gardini and Australian poet Kate Lilley. It explores Sabine Sielke's contention that differences in sexuality have predominantly constructed female sexuality as victimisation. In contrast, contemporary poets like Gardini and Lilley unsettle such alignment, demonstrating not only its constitutive limits but also providing a counter-discourse of radicalised agency.

Professionals’ perspectives about the challenges of using interpreters in child sexual abuse interviews

Interpreters play a crucial role in many investigative interviews with child complainants of sexual abuse; however, little has been written about the interpreting process from the perspective of the interviewers. This study elicited interviewers’ perspectives about the challenges of using interpreters, with the aim of understanding how investigative interviews could be improved. The participants consisted of 21 investigative interviewers and prosecutors of child abuse cases (from a range of jurisdictions) who use interpreters on a regular basis. Thematic analysis of semi-structured interviews with the professionals about the interpreting process revealed two main challenges particular to child abuse interviews, namely the interpreters’ lack of preparedness to deal with the traumatic and sensitive nature of children's abuse histories, and an insufficient understanding of ‘best-practice’ child interview process. The recommendations focus on the need for more specialised training for, and screening of, interpreters, and more extensive use of pre-conferencing to familiarise children with the interpreter-mediated interview process.

Pathway to justice: Examining the attrition of child sexual abuse cases

The attrition of child sexual abuse cases from the criminal justice process was explored. Recommendations to prevent attrition included: more effective communication between stakeholders; enabling connections between children and adults to facilitate disclosures; introduction of peer support programs to prevent withdrawal; and educating children about sexual victimisation to reduce withdrawal.

Social network analysis resolves temporal dynamics of male dominance relationships

Social organization is often studied through point estimates of individual association or interaction patterns, which does not account for temporal changes in the course of familiarization processes and the establishment of social dominance. Here, we present new insights on short-term temporal dynamics in social organization of mixed-sex groups that have the potential to affect sexual selection patterns. Using the live-bearing Atlantic molly (Poecilia mexicana), a species with pronounced male size polymorphism, we investigated social network dynamics of mixed sex experimental groups consisting of eight females and three different-sized males over a period of 5 days. Analyzing association-based social networks as well as direct measures of spatial proximity, we found that large males tended to monopolize most females, while excluding small- and medium-bodied males from access to females. This effect, however, emerged only gradually over time, and different-sized males had equal access to females on day 1 as well as day 2, though to a lesser extent. In this highly aggressive species with strong social dominance stratifications, the observed temporal dynamics in male-female association patterns may balance the presumed reproductive skew among differentially competitive male phenotypes when social structures are unstable (i.e., when individual turnover rates are moderate to high). Ultimately, our results point toward context-dependent sexual selection arising from temporal shifts in social organization.
