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.     

A Direct Aqueous Derivatization GSMS Method for Determining Benzoylecgonine Concentrations in Human Urine

A sensitive and reliable method for extraction and quantification of benzoylecgonine (BZE) and cocaine (COC) in urine is presented. Propyl‐chloroformate was used as derivatizing agent, and it was directly added to the urine sample: the propyl derivative and COC were then recovered by liquid–liquid extraction procedure. Gas chromatography–mass spectrometry was used to detect the analytes in selected ion monitoring mode. The method proved to be precise for BZE and COC both in term of intraday and interday analysis, with a coefficient of variation (CV) <6%. Limits of detection (LOD) were 2.7 ng/mL for BZE and 1.4 ng/mL for COC. The calibration curve showed a linear relationship for BZE and COC (r² >0.999 and >0.997, respectively) within the range investigated. The method, applied to thirty authentic samples, showed to be very simple, fast, and reliable, so it can be easily applied in routine analysis for the quantification of BZE and COC in urine samples.     

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.     

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.

A Smaller Military To Fight the War on Terror

The defense budget can be reduced and the U.S. military downsized because (1) the nation-state threat environment is markedly different than it was during the Cold War, and (2) a large military is not necessary to combat the terrorist threat. In fact, the Islamist terrorist threat is relatively undeterred by the U.S. military presence abroad, and U.S. forces abroad, particularly those deployed in Muslim countries, may do more to exacerbate than to diminish the threat. The arduous task of dismantling and degrading the terrorist network will largely be the task of unprecedented international intelligence and law enforcement cooperation, not the application of large-scale military force. To the extent the military is involved in the war on terror, it will be special forces in discrete operations against specific targets rather than large-scale military operations.     

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.     

环境应急管理机构:使命、境遇及改革

突发环境事件应急管理是各级环境保护行政主管部门的一项重要职责,这项职责目前由国家和一些地方环境保护行政主管部门所属的环境应急与事故调查中心承担。按照有关规定并从现实运行情况看,作为事业单位设置的环境应急与事故调查中心面临着其自身难以突破的困境。本文在剖析其定位、明确其归类的基础上,按照中央关于行政管理体制改革的精神,研究环境应急与事故调查中心的改革问题。     

Welfare Regimes in Latin America: Capturing Constellations of Markets,Families, and Policies

This article presents both a theoretical framework and a methodology that attempt to capture the complex interactions among labor markets, families, and public policy that currently constitute Latin American welfare regimes. Drawing on cluster analysis based on available data for 18 countries, the study identifies three welfare regimes. Two are state welfare regimes: protectionist (e.g. Costa Rica) and productivist (e.g. Chile); one is nonstate familiarist (e.g. Ecuador and Nicaragua). In a region where people's well‐being is deeply embedded in family relationships, closer scholarly attention to how social structures interact with public policy bears not only academic interest but also policy implications, particularly for adapting particular welfare regimes to the local welfare mix.
