Objectives

The need for re-entry assistance is widely acknowledged, but specifics about what services actually lead to reduced recidivism are hard to find—at least among rigorous studies. This is a critical issue: at a time when there appears to be unprecedented support for expanding rehabilitative programs for offenders, there is a dearth of rigorously vetted program options from which to choose.

Methods

Collaborating with a nationally known employment-focused reentry program in Southern California, the authors compared employment, housing, and recidivism outcomes of reentering offenders (n?=?217) who were either randomized into the program or simply provided with a list of community resources. This approach was possible because the number of applicants at the time exceeded program capacity. Outcomes were based on self-report interviews conducted 1-year post-randomization and arrest records reflecting a 2-year follow-up period. The follow-up rate for interviews was 87 %.

Results

No significant differences were found for any of the between-group comparisons on any of the major intervention outcomes.

Conclusions

Findings from the study suggest a greater need to apply randomized designs to more carefully evaluate current reentry efforts. Methodological challenges of field experiments are also discussed.  相似文献

Articular cartilage was examined to determine its decomposition sequence and its potential for assessing the postmortem interval. Scanning electron microscopy of articular cartilage from buried porcine trotters showed the presence of microcrystals on the synovial surface. These orthorhombic pyramidal or “coffin”‐shaped crystals, appeared at 3 weeks (22 days) after interment and disappeared after 6 weeks. The disappearance of these crystals was linked to decompositional changes to the integrity of the synovial joint. The formation and disappearance of these crystals was associated with a pH change at the cartilage surface. Scanning electron microscopy–energy‐dispersive X‐ray (SEM‐EDX) analysis showed that the five main elements contained within these crystals were carbon, nitrogen, oxygen, magnesium, and phosphorous. Such elemental analysis suggested the crystals may be struvite (MgNH4PO46(H2O)). Bacteria cultured from the cartilage synovial surface produced struvite crystals when grown in suitable media and were identified by DNA analysis to be Comamonas sp.  相似文献

As early as the 1970's, privacy studies recognised that ‘anonymisation’ needed to be approached with caution. This caution has since been vindicated by the increasing sophistication of techniques for reidentification. Yet the courts in the UK have so far only hesitatingly grappled with the issues involved, while European courts have produced no guidance.  相似文献

From time to time the Court of Appeal feels the need to steer inferior courts and tribunals away from an over-enthusiastic application of a particular direction of travel signposted by its own previous decisions. In the Edem judgment, published on 7 February 2014, the court has taken the opportunity to restrict significantly the application of its decision more than a decade ago in Durant v. Financial Services Authority, 1 a case that has been relied on by many commercial data protection practitioners to deny subject access or the wider application of the Data Protection Act 1998 on the grounds that the data were not personal in that they did not relate to the individual in question even though the individual's name appeared as part of the data.  相似文献

Data collection using the life event calendar method is growing, but reliability is not well established. We examine test–retest reliability of monthly self-reports of criminal behavior collected using a life event calendar from a random sample of minimum and medium security prisoners. Tabular analysis indicates substantial agreement between self-reports of drug dealing, property, and violent crime during a baseline interview (test) and a follow-up (retest) approximately 3 weeks later. Hierarchical analysis reveals that criminal activity reported during the initial test is strongly associated with responses given in the retest, and that the relationship varies only by the lag in days between the initial interview and the retest. Analysis of validity reveals that self-reported incarceration history is strongly predictive of official incarceration history although we were unable to address whether subjects could correctly identify the months they were incarcerated. African Americans and older subjects provide more valid responses but in practical terms the differences in validity are not large.  相似文献

The objective of this study was to investigate psychological or physical violence associated with the use of alcohol, in residences of individuals in Brazil and, also describe the social characteristics of aggressors and victims. Therefore, this study expects to contribute to studies in Brazil that seek to clarify the relations between alcohol and violence in residences. A total of 454 respondents, 12–65 years old, were assessed, they were sorted by the Kish method, and the residences randomly. The SAMHSA questionnaire was utilized after translated and adapted to Brazilian conditions. 26% of the individuals reported psychological violence, and 16% reported physical violence. The study’s main results set the differences in the reports for physical violence (OR 7, 95% CI: 4–13) and psychological violence (OR 5, 95% CI: 3–8) in residences where someone arrived or became intoxicated with alcohol (P < 0.05). 50% of the aggressors were under the effects of alcohol, and 77% of the victims were relatives of their aggressors. Acts of violence are not necessarily associated with alcohol consumption. Men and women reported acts of domestic violence; psychological violence was the most prevalent form. Men are currently the primary aggressors, while women are primarily the victims  相似文献

Much has been written about sex trafficking in the past decade, although empirical studies have remained few. Even less research has been done on those who make a living by facilitating the movement of women and children in the sex industry. This paper is based on a three-year study in Tijuana, Mexico, in which 92 sex trade facilitators were interviewed. Findings suggest a far more complex social process than portrayed by the anti-trafficking literature. Men and women of diverse backgrounds developed niches in Tijuana’s sex industry, by bringing women into contact with customers. This business appeared to be dominated by Mexican entrepreneurs, with no evidence of any systematic collaborations with either local criminal organizations or foreign traffickers. There appeared to be no shortage of women willing to work in the sex industry, suggesting limited prospect for coerced prostitution. Still, a small number of pimps reported using “persuasion” to recruit women of particular types from interior Mexico. Commissions or referral fees were the most common form of income received by pimps for their services, and the rules on how money was to be made and split between sex workers and venue owners appeared well established. While a few respondents could sustain a livelihood through pimping, the majority held other jobs.  相似文献

Aortic aneurysm refers to the pathological dilatation of the normal aortic lumen involving one or several segments. Thoracic aortic aneurysms are much less common than aneurysms of the abdominal aorta. Descending thoracic aortic aneurysm leading to dissection and spontaneous rupture is a potentially catastrophic illness. Although rare, dissection and rupture of a preexisting aortic aneurysm have been reported during pregnancy and early puerperium. To the best of our knowledge, such cases among young pregnant women are rarely reported in literature. Herein, an autopsy case of spontaneous rupture of a clinically undiagnosed descending thoracic aortic aneurysm during early puerperium in a young woman is presented along with the review of relevant literature. The victim was found dead on her hospital bed on the seventh day of puerperium. Autopsy with ancillary investigations revealed that the young woman died because of hemothorax from a ruptured dissecting descending thoracic aortic aneurysm secondary to chronic aortitis.  相似文献
