ABSTRACT

Under what conditions are rebel groups successfully incorporated into democratic politics when civil war ends? Using an original cross-national, longitudinal dataset, we examine political party formation by armed opposition groups over a 20-year period, from 1990 to 2009. We find that former armed opposition groups form parties in more than half of our observations. A rebel group’s pre-war political experience, characteristics of the war and how it ended outweigh factors such as the country’s political and economic traits and history. We advance a theoretical framework based on rebel leaders’ expectations of success in post-war politics, and we argue that high rates of party formation by former armed opposition groups are likely a reflection of democratic weakness rather than democratic robustness in countries emerging from conflict.  相似文献

This study reports findings from a study of nine juvenile drug courts (JDCs) from across the US. A quasi-experimental design, with one-to-one matching on possible confounders and sociodemographics, was used for the outcome assessment (n?=?1372). Baseline and outcome data were drawn from justice system records. Although there is variation across sites and, to some extent, outcomes, these JDCs were generally ineffective in reducing recidivism. Similar findings have emerged in other recent studies of JDCs. Given the results of this study and others, it is essential that juvenile courts work to improve the effectiveness of JDCs by increasing adherence to known principles of effective intervention.  相似文献

Using the Serious and Violent Offender Reentry Initiative data-set, substance use and mental health needs of released inmates are examined to explore whether there is a positive relationship between pre-release services and behavioral health treatment access at three months post-release. Two weighted hierarchical linear models were run testing the effects of three key pre-release services: pre-release needs assessment, pre-release linkage with inmates’ post-release case managers, and pre-release assistance with accessing post-release health insurance. Results demonstrate that pre-release needs assessment significantly increases the odds of receiving post-release substance abuse treatment, and case management linkage and assistance with accessing health insurance significantly increase the odds of mental health treatment after release. Policy implications for reentry service provision targeting behavioral health needs, and directions for future research, are discussed.  相似文献

When analyzing DNA from exploded pipe bombs, quantities are often in trace amounts, making DNA typing extremely difficult. Amplifying minute amounts of DNA can cause stochastic effects resulting in partial or uninterpretable profiles. Therefore, the initial DNA collection from “touch” evidence must be optimized to maximize the amount of DNA available for analysis.This proof-of-concept study evaluated two different swab types with two direct amplification strategies to identify the most effective method for recovering DNA from common pipe bomb substrates. PVC and steel pipes, electrical tape, and copper wire spiked with epithelial cells were swabbed with cotton or microFLOQ® Direct Swabs and amplified directly or via a pre-treatment prior to STR amplification.Not only was the microFLOQ® Direct Swab protocol the quickest method with the least risk of contamination, but in combination with direct amplification, the microFLOQ® Direct Swabs also generated the most complete STR profiles.  相似文献
