Young adult sexual offenders with emerging personality disorders: developmental and offence-related characteristics and treatment engagement

ABSTRACT

In the context of the UK Government’s Offender Personality Disorder (OPD) Strategy, large numbers of high-risk young adult sexual offenders with emerging personality disorders are being screened for inclusion onto specialist intervention pathways (the OPD Pathway). However, little is currently known about the clinical and offence-related needs of this population or their impact on treatment engagement. The current study investigated the developmental, personality and offence-related characteristics of 87 incarcerated young adult sexual offenders, comparing those screened in to the pathway and those not screened in. Fifty per cent of the sample were potentially eligible for the OPD pathway. OPD eligible cases were found to have significantly higher rates of parental difficulties, developmental trauma, and childhood behavioural difficulties and to present with significantly higher rates of previous violent and sexual offences, previous allegations of sexual offences, and to have used physical coercion in their offences. The OPD sample was also significantly less likely to have pre-pubescent victims and more likely to refuse treatment, with over 70% failing to engage with the Sex Offender Treatment Programme (SOTP). SOTP non-engagement among OPD cases was most strongly predicted by categorical offence denial. Comparisons are made with the broader adolescent sexual offender literature.     

A study of stranger rapists from the English high security hospitals

Abstract

Heterogeneity hinders our understanding of sexual violence; but does this problem extend to stranger rape and, if so, would the construction of homogeneous subtypes advance our understanding of this crime and aid criminal investigations and clinical practice? To answer these questions, 41 stranger rapists from the English high security hospitals were examined using version 3 of the Massachusetts Treatment Centre rapist typology (MTC:R3) and multidimensional scaling (MDS). The MTC:R3 suggested that sexual desire and opportunism were the primary motivations for these men, but that proportionately more psychopaths were violent and sadistic. In accordance with previous research, the men experienced problematic childhoods and displayed high rates of criminality and psychiatric morbidity in adulthood. However, MDS found that rapist histories and offence behaviours generally divide into sexual and violent themes. These results have important implications for theory, criminal investigations and clinical practice.

High‐Throughput STR Analysis for DNA Database Using Direct PCR,

Since the Korean criminal DNA database was launched in 2010, we have focused on establishing an automated DNA database profiling system that analyzes short tandem repeat loci in a high‐throughput and cost‐effective manner. We established a DNA database profiling system without DNA purification using a direct PCR buffer system. The quality of direct PCR procedures was compared with that of conventional PCR system under their respective optimized conditions. The results revealed not only perfect concordance but also an excellent PCR success rate, good electropherogram quality, and an optimal intra/inter‐loci peak height ratio. In particular, the proportion of DNA extraction required due to direct PCR failure could be minimized to <3%. In conclusion, the newly developed direct PCR system can be adopted for automated DNA database profiling systems to replace or supplement conventional PCR system in a time‐ and cost‐saving manner.     

School Violence Prevention

Abstract

Objective: This study was designed to describe the level of violence in three high schools and to test the effects of universal and targeted strategies to reduce this violence.

Design:A repeated measures design with two baseline scores and two intervention scores was used during a two year period. Two rural high schools served as control schools with a single intervention high school.

Participants: All freshmen at the three high schools completed a self-report measure of school violence; 420 completed the study at the end of their sophomore year.

Method: Multiple universal and targeted interventions to prevent school violence were used for slightly more than one year. Scores on student Victimization and Perpetration, gathered one year apart, were compared using a pre-test post-test model.

Findings: Student reports of perpetration at the intervention school were significantly lower than the combined scores at the control school. Students, teachers, and administrators reported improved awareness, knowledge, and skills to implement violence prevention programs.

Conclusions: A comprehensive program that includes university and high school partnerships has the capability to reduce school violence during a short period. Despite limitations to the study, continued use of research partnerships to decrease school violence is war-ranted.

The Relationship Between High Education and Labor Market in Western Balkan Countries

This paper deals with the relationship between high education and labor market in Western Balkan countries. Having in mind that all these countries are in transitional process, suffering from poor economics, poor level of investments, and high unemployment rates, it would be wise that the governments and political elites put the quality of knowledge high on agenda, regarding it as the vital incentive instrument for economic and social development. All social and political subjects should be devoted to procuring good quality of knowledge, which is sensitive to the labor market＇s needs in all fields. This study attempts to find answer on the question why it is not so, making qualitative, quantitative, and empirical research. It analyzes the relationship between high education and labor market＇s needs, identifies main factors which influence this relationship, focusing on main influence of political interests and values. The paper presents rare good cases, as lessons from experience for the future.
