Analysis of cognitive inhibition and flexibility in juvenile delinquents

Executive functions are still developing during adolescence. It is important to analyse if juvenile delinquency is related to a delay in the development of these functions. The objective of this study was to analyse cognitive inhibition and flexibility, two components of executive functions, in juvenile delinquents. Participants were 81 males, 17.46 ± 1.60 years old. Three groups were compared: a juvenile delinquent inmate group (IG), an age-paired group (APG), and an age- and education-paired group (AEPG). A modified Stroop task was used to assess cognitive inhibition and flexibility. The IG and the AEPG (low-education adolescents) had significantly more difficulties than the APG on inhibition; the IG and the AEPG had no significant differences. No group differences were found on flexibility. Since all low-education adolescents have difficulties on inhibition, these difficulties are not an exclusive characteristic of juvenile delinquents. Analysis of cognitive processes in juvenile delinquents must control for education to determine how specific are the difficulties found in these adolescents.     

Microscopic Pattern of Bone Fractures as an Indicator of Blast Trauma: A Pilot Study

The assessment of fractures is a key issue in forensic anthropology; however, very few studies deal with the features of fractures due to explosion in comparison with other traumatic injuries. This study focuses on fractures resulting from blast trauma and two types of blunt force trauma (manual compression and running over), applied to corpses of pigs; 163 osteons were examined within forty fractures by the transmission light microscopy. Blast lesions showed a higher percentage of fracture lines through the Haversian canal, whereas in other types of trauma, the fractures went across the inner lamellae. Significant differences between samples hit by blast energy and those runover or manually compressed were observed (p < 0.05). The frequency of pattern A is significantly higher in exploded bones than in runover and compressed. Microscopic analysis of the fracture line may provide information about the type of trauma, especially for what concerns blast trauma.     

Distribution of Enantiomers of Methadone and Its Main Metabolite EDDP in Human Tissues and Blood of Postmortem Cases

Knowledge concerning the distribution of methadone in postmortem human tissue and the effect of postmortem redistribution on methadone is today limited making the choice of a suitable substitute for femoral blood difficult when this is not available. Cardiac blood, femoral blood, muscle, and brain tissue concentrations of the enantiomers of methadone and its metabolite 2‐ethyl‐1,5‐dimethyl‐3,3‐diphenylpyrrolinium were recorded for 155 postmortem cases. Brain and muscle tissue concentrations exceeded the femoral blood concentrations with a median fold of 2.3 and 1.6, respectively, but both had a better correlation than cardiac blood to femoral blood concentrations. The Kruskal–Wallis test showed a significant dependency on time and body mass index for some of the matrix ratios over femoral blood. We conclude brain or muscle tissue may constitute a better alternative for measurement of methadone than cardiac blood for situations in which femoral blood is not available, despite concentrations in both matrices being systematically higher.     

A Natural Experiment in Political Decentralization: Local Institutions and Citizens' Political Engagement in Uruguay

The potential democratizing effect of political decentralization reforms has been a matter of substantial theoretical and empirical debate. This article analyzes the effect of local democratic institution building on the political attitudes and behavior of citizens living in small towns in Uruguay. More specifically, using a natural experiment design, this research seeks to establish the causal impact of recently established elections of local authorities on individuals' political engagement. It develops a comparative case study analyzing the consequences of this institutional innovation in two towns. It shows that individuals from the town where citizens have the opportunity to elect their local authorities have more positive attitudes toward politics than those from the town without such elections.

THE PROCESS OF DEMILITARIZATION AND THE REVERSIBILITY OF THE PEACE PROCESS IN NORTHERN IRELAND

The process of militarization has permeated Northern Ireland society both overtly and in more subtle and pervasive ways. Since the Good Friday Agreement in 1998, reductions in state military personnel and infrastructure have been made and several acts of paramilitary decommissioning of weapons carried out. However, the political culture and discourse remains combative and bifurcated as the democratic institutions and processes struggle to achieve viability. Support for the Agreement has faltered as the raised expectations of improvements in quality of life, particularly in communities worst affected by the Troubles, have not been met. Vacuums such as the rolelessness amongst former combatants and gaps in policing have contributed to internecine conflict. As in South Africa, there has been a transition from political to criminal violence in local communities. A formal process of demobilization, demilitarization and reintegration of former paramilitary actors, combined with training in political skills would resolve some of these issues and ensure the irreversibility of the peace process itself.     

Think Tanks in Iceland

This article maps the landscape of think tanks in Iceland. It shows that think tanks are very few and insignificant in Icelandic policymaking. In the literature, the growth of think tanks in European countries with corporatist pasts has been linked to a change to a more pluralist system of interest representation. The case of Iceland lends support to this claim. In contrast to Scandinavia, corporatism remains entrenched in Iceland. But although there is a very limited market for local think tanks in Iceland, it is nevertheless recognized by political actors that touting policy advice offered by prestigious (international) think tanks can bring political benefits. This is also demonstrated in the article, showing that the influence of think tanks transcends at times national borders.
