The neuropsychology of impulse control: New insights into violent behaviors

Environmental stressors, especially within penal environments, have led to increased violence within correctional settings. Knowledge of the neuropsychology of impulse control needs to be within the scope of knowledge of correctional officials at all levels. In this article we attempt to present the basics of neuropsychology of aggression along with the corresponding diagnostic classifications and general recommendations for environmental controls which may serve as strategies for reducing the incidence of disruption within the correctional setting.     

Understanding the Politics of Latin America's Plural Lefts (Chávez/Lula): social democracy,populism and convergence on the path to a post-neoliberal world

This article explores the academic and public debate on the politics of Latin America's twenty-first century turn towards the left. It rejects dichotomous categorisations of ‘social democratic’ and ‘populist’ lefts as a disciplinary move by neoliberals that appeals to entrenched liberal predispositions. It suggests that such classificatory taxonomies are directly linked to an impoverished notion of the political, in which a politics of exalted expertise and enlightenment, based on reason, rationality and objectivity is juxtaposed against a lesser sphere of emotion, passion and ‘personalism’. This underlying dualism, which permeates academic disciplines and crosses lines of ideology, tracks established markers of hierarchical distinction in societies profoundly divided along multiple lines of class and cultural capital. This is explored through an analysis of the discourse of Chávez vis-a-vis Lula, while offering an appreciation of the subaltern origin of Lula's distinctive style of political leadership, from trade unionism to the presidency, based upon the creation of spaces of convergence.     

Feasibility of a computerized intervention for offenders with substance use disorders: a research note

Objectives

Despite evidence that treatment is effective in reducing recidivism among inmates with substance use problems, scarce resources mean that few of those in need of treatment actually receive it. Computerized substance abuse interventions could be used to expand access to treatment in prisons without placing an undue burden on resources. The major aim of the study was to compare treatment conditions in terms of their service utilization, skills acquisition, and treatment satisfaction.

Methods

The study recruited men and women with substance use disorders from 10 prisons in 4 states. In an open label clinical trial, 494 subjects were randomly assigned either to the Experimental condition, a computerized drug treatment intervention, the Therapeutic Education System (TES; n?=?249), or to the Control condition, Standard Care (n?=?245). Chi-square tests compared groups on categorical variables and independent samples t tests were used for interval level continuous variables.

Results

Initial evidence demonstrated: (1) comparable group rates of session attendance and high rates of TES module completion for experimental subjects; (2) comparable group gains in the development of coping skills; and (3) a more favorable view of TES than of Standard Care.

Conclusions

Collectively, these results show that a computerized intervention, such as TES, can be implemented successfully in prison. Given the barriers to the delivery of substance abuse treatment typically encountered in correctional settings, computerized interventions have the potential to fill a significant treatment gap and are particularly well suited to inmates with mild to moderate substance use disorders who often are not treated.     

The reincorporation and redistribution of trace geoforensic particulates on clothing: An introductory study

Two experimental studies were undertaken to investigate the processes of reincorporation and redistribution of trace evidence on garments when worn by a suspect or a victim (reincorporation) or after the garments have been seized and packaged for subsequent forensic analysis (redistribution). The first experiment utilised UV powder, an established proxy for geoforensic trace particulates and the second experiment utilised daffodil pollen transferred onto garments under conditions that mimicked forensic reality. It was demonstrated that reincorporation of trace particulates occurs from upper to lower parts of the same garment and also from upper garments to lower garments. Reincorporation also occurred to all areas of the lower garments, however the highest concentration of particulates was found to be the lap area of the jeans. Particulates also tended to be preserved around technical details such as stitching or relief design features of the garments. Thus the decay of particulates after a contact has been made does not necessarily involve a loss of those particulates from the entire system. These findings have implications for the interpretation of trace evidence when seeking to establish the source of initial contacts or the chronology of pertinent events. The second study demonstrated that folding and packaging items of clothing leads to a redistribution of any trace particulate evidence that is present thereby eliciting an alteration in the spatial distribution of that evidence. There is therefore a necessity to take the context of trace evidence into account and also to follow protocols that are sensitive to these aspects of trace evidence behaviour as a failure to do so may have consequences for the correct interpretation of such evidence.
