The impact of pre-treatment responsivity and treatment participation on violent recidivism in a violent offender sample

This study assessed whether pre-treatment responsivity (psychopathy, motivation to attend treatment, denial and minimisation of offending behaviour, and feelings of guilt or shame) predicted violent recidivism and/or moderated the effectiveness of a violence intervention programme. Participants were 114 male violent offenders who were referred to a structured violent offender group treatment programme; 84 offenders commenced the programme. Results showed that treatment completion did not have a significant main effect on recidivism but that psychopathy scores moderated the effects of treatment. Offenders with high scores on the Psychopathy Checklist: Screening Version (PCL:SV) who were rated as having good engagement with treatment, or who completed treatment, had similar violent recidivism rates compared to offenders with low PCL:SV scores. In contrast, offenders with high PCL:SV scores who dropped out of treatment or were poorly engaged had significantly higher rates of violent recidivism. These findings indicate that treatment effectiveness could be enhanced, and greater reductions in recidivism achieved, if programmes find ways to engage and maintain psychopathic offenders in treatment.     

Assessing effective participation in vulnerable juvenile defendants

Effective participation in trial is outlined under article 6 of the European Convention on Human Rights and refers to the ability to understand and engage in trial. Juvenile defendants are often referred to psychologists or psychiatrists by their solicitors to establish ‘effective participation’ capacity. In the USA, key components to participate effectively are defined and standardised assessments available. In the UK, no formal measures exist. A consecutive series of 20 adolescents aged 12–20 years, referred by their solicitors to our service, were assessed using a standardised battery and a semi-structured interview designed to assess effective participation. Fifty-five per cent had at least one neurodevelopmental disorder. Low IQ was common and 50% had age-equivalent language scores below 10 years. Rates of depression, anxiety and PTSD were high. Knowledge about trial was poor. These findings have implications for Criminal Justice System professionals and to ensure fair trials for young defendants.

Sub-surface characterisation of latest-generation identification documents using optical coherence tomography

The identification of individuals, particularly at international border crossings, coupled with the evolving sophistication of identity documents are issues that authorities must contend with. Particularly, the ability to distinguish legitimate from counterfeit documents, with high throughput, sensitivity, and selectivity is an ever-evolving challenge.Over the last decade, an increasing number of security features have been introduced by authorities in identification documents. The latest generation of travel documents (such as passports and national ID cards) forego paper substrates for several layers of polycarbonate, allowing security features to be embedded within the documents. These security features may contain information at either the superficial and sub-surface levels, thus increasing the document’s resilience to counterfeiting.As the documents become harder to forge, so does the sophistication of forgery detection. There appears to be an unmet and evolving need to identify such sophisticated forgeries, in a non-destructive, high throughput manner.In this publication, we report on the application of optical coherence tomography (OCT) imaging on assessing security features in specimen passports and national ID cards. OCT allows sub-surface imaging of translucent structures, non-destructively enabling quantitative visualisation of embedded security features.

Can we explain the Santa Clara county housing market?

Abstract

Santa Clara County has recently had the highest house prices of any large housing market in the nation. Part of the explanation lies in the extraordinarily low user cost of housing caused by the interaction of high incomes and the tax deductions available to homeowners. But this article also evaluates whether changes in stock wealth have been responsible for the recent increase in housing prices in Santa Clara County.

Although three different stock market measures add explanatory power to a model of housing prices in the region, none of these indexes predicts the housing price increases seen in 1999 and 2000. In fact, the within‐sample models have .R‐squares of only 0.22, and even the best model (based on the Standard & Poor's 500) does not forecast well out of sample. Still, the market is unusual in that stock prices seem to have some impact on house prices.
