An Optimized Centrifugal Method for Separation of Semen from Superabsorbent Polymers for Forensic Analysis

Connection of a perpetrator to a sexual assault is best performed through the confirmed presence of semen, thereby proving sexual contact. Evidentiary items can include sanitary napkins or diapers containing superabsorbent polymers (SAPs), complicating spermatozoa visualization and DNA analysis. In this report, we evaluated the impact of SAPS on the current forensic DNA workflow, developing an efficient centrifugal protocol for separating spermatozoa from SAP material. The optimized filtration method was compared to common practices of excising the top layer only, resulting in significantly higher sperm yields when a core sample of the substrate was taken. Direct isolation of the SAP‐containing materials without filtering resulted in 20% sample failure; additionally, SAP material was observed in the final eluted DNA samples, causing physical interference. Thus, use of the described centrifugal‐filtering method is a simple preliminary step that improves spermatozoa visualization and enables more consistent DNA yields, while also avoiding SAP interference.     

Advocacy Perspectives on the Greenbook: Interviews with Domestic Violence Advocates from Three Federally Funded Greenbook Sites

Between 2000 and 2005, six sites engaged in local implementation of recommendations made in Effective Intervention in Domestic Violence and Child Maltreatment: Guidelines for Policy and Practice (the Greenbook), published by the National Council of Juvenile and Family Court Judges in 1999. This three‐part article reflects recorded conversations in June and July of 2019 and captures the perspectives of five domestic violence advocates who participated in local Greenbook implementation (in El Paso County, CO; San Francisco County, CA; or Santa Clara County, CA) and their thoughts on the Greenbook work then, since then, and going forward.     

Chill out! Mooting and the affective domain

A vital aspect of successful advocacy is effective engagement by the advocate with the Bench. However, even where mooters have innate skills and talents, they are susceptible to sub-optimal performance where anxiety impedes their transition from innate skill to competition. Stage fright is common in many fields where public performance of a repertoire is the crucial and determinative measure of achievement. However, while anxiety is an inevitable, and often negative, aspect of any performance, there is in fact a range of anxietal intensity that is conducive to optimal performance. Assisting future advocates to recognise their optimal level of anxiety, and manage their anxiety throughout the preparation and participation phases of moot competitions is a significant role for the moot coach. This article explores anxiety as a principal artefact of the affective domain, its relevance to advocacy, and proposes a model against which moot coaches can frame preparation of mooting teams against a principled construct of the anxiety/mooting relationship. In so doing, it positions the affective domain as it relates to mooting in context with the cognitive and psychomotor domains.     

Traumatic brain injury in a forensic intellectual disability population

Traumatic brain injury (TBI) screening in forensic populations has been recommended, due to a high prevalence, links to specific offence profiles and poorer outcomes, such as higher rates of psychiatric disturbance, longer stays in prison, and reoffending. Research focusing on TBI among offenders with intellectual disability (ID) is lacking. This study therefore describes the implementation of TBI screening using the Brain Injury Screening Index (BISI©), TBI prevalence and correlates in a forensic ID service. TBI appeared under recorded in case notes, with considerably more patients self-reporting TBI. Reported causes of TBI differed somewhat to the general population, including childhood physical abuse, self-harming behaviour, and assault. Approximately one-third of injuries did not receive any treatment. Though further adaptations may be required on current screening measures for TBI in offenders with ID, screening can provide valuable information, contributing positively to individual patient therapeutic and risk formulations.     

An Investigation of Personality Traits in Relation to Adolescent School Absenteeism

We examined the Big Five personality traits of Agreeableness, Conscientiousness, Emotional Stability, Extraversion, and Openness, as well as four narrower traits of Aggression, Optimism, Tough-Mindedness, and Work Drive in relation to absences from school for middle- and high-school students. Participants were 248 seventh grade students, 321 tenth grade students, and 282 twelfth grade students. Most of the Big Five absence correlations were significant in the expected direction at all 3 grade levels. While Aggression, Optimism, Work Drive were significantly related to absences, only Work Drive added incremental variance to the prediction of absences beyond the Big Five traits. Study results were generally similar across grade levels. Findings were discussed in terms of dispositional absenteeism, the generalizability of the Big Five trait model, and the utility of more narrowband traits. Implications were drawn for early identification of absence-prone students and the precedent role of personality variables in school absence research on the effects of other variables, programs, and interventions.     

Adolescents’ Experiences of Victimization: The Role of Attribution Style and Generalized Trust

Positive attribution style, negative attribution style, and generalized peer trust beliefs were examined as mediators in the relationship between adolescents’ peer victimization experiences and psychosocial and school adjustment. A total of 280 (150 female and 130 males, M_age = 13 years 4 months, SD_age = 1 year 1 month) adolescents completed measures of peer victimization, global self-worth, depressive symptoms, social confidence, school liking, loneliness, attribution styles, and generalized trust beliefs. Multigroup path analysis revealed that: (a) negative attribution style mediated the relationship between cyber victimization and school liking and depressive symptoms for males and females; (b) positive attribution style mediated the relationship between cyber victimization, school liking, global self-worth, and depressive symptoms for females; and (c) generalized peer trust beliefs mediated the relationship between social victimization, depressive symptoms, social confidence, and loneliness for females. Consequently, attribution style and generalized trust beliefs differentially influence the relationship between peer victimization and adjustment.     

The thin blue line in schools: New evidence on school-based policing across the U.S.

U.S. public school students increasingly attend schools with sworn law enforcement officers present. Yet little is known about how these school resource officers (SROs) affect school environments or student outcomes. Our study uses a fuzzy regression discontinuity (RD) design with national school-level data from 2014 to 2018 to estimate the impacts of SRO placement. We construct this discontinuity based on the application scores for federal school-based policing grants of linked police agencies. We find that SROs effectively reduce some forms of violence in schools, but do not prevent gun-related incidents. We also find that SROs intensify the use of suspension, expulsion, police referral, and arrest of students. These increases in disciplinary and police actions are consistently largest for Black students, male students, and students with disabilities.     

The Developmental Unfolding of Sibling Influences on Alcohol Use over Time

Research has long demonstrated that siblings are similar in their alcohol use, however much of this work relies on cross-sectional samples or samples of adolescents alone and/or exclusive focus on older siblings’ impact on younger siblings. Using a three time-point design from early adolescence to early adulthood (M ages?=?14.9, 18.3, and 22.4 years, respectively; 55% female; 54% European ancestry, 38% Asian ancestry), we evaluated the prospective older and younger sibling influences on alcohol use across time (N?=?613 sibling pairs; 35% sisters, 26% brothers, 39% mixed-gender; average age difference?=?2.34 years; 34% full-biological siblings, 46% genetically-unrelated adopted siblings, 20% pairs where one child was the biological offspring of parents and the other was adopted). The results from both the traditional and random-intercept cross-lagged panel analyses showed that older siblings’ alcohol use predicted younger siblings’ alcohol use across each developmental transition and across a variety of sibling contexts (e.g., gender composition, age difference, genetic relatedness). On the other hand, younger siblings’ alcohol use only predicted older siblings’ alcohol use when siblings were close in age (1.5 years or less) and under conditions of high sibling companionship. These results add to a body of literature illustrating how both older and younger siblings are important socializing agents of adolescent and early adult alcohol use. Assessing or co-treating siblings for alcohol problems may be an important add-on to existing adolescent and early adult alcohol prevention and intervention programs.     

‘Purifying’ the public world: feminist vigilantes in late Victorian England

In late nineteenth-century England, a number of feminists confronted prostitution through the closing of brothels and the expulsion of prostitutes from places of entertainment. Feminist historians have either understood this behaviour as reflective of feminist' powerlessness within the largely non-feminist movement for social purity, or they have neglected the behaviour and concentrated on the aspects of these women' work that appear more positive to feminists today. Neither approach attempts to understand why women took this more repressive stance and thought of it as feminist. To understand the actions of these women, it is necessary to recognise that their vision of a ‘purified’ public and private world was often informed by religious beliefs and adherence to temperance. Concern with the morality of public space also related to women' desire for safety in public places. And their ‘repressive’ and statist actions related in part to feminist philanthropist' changing attitude toward local government.
