Purpose

Prior theory and research suggest that inmate visitation can reduce misconduct in prison. However, prior studies have not accounted for the longitudinal and heterogeneous nature of these experiences. This paper addresses this research gap by examining variation in visitation experiences and the relationship between patterns of visitation and misconduct.

Methods

Using a cohort of offenders incarcerated in Florida between 2000 and 2002, group-based trajectory model analyses were used to identify groups of inmates based on their visitation and misconduct patterns. Dual trajectory analysis was used to then assess the extent to which the development of visitation and misconduct patterns are interrelated.

Results

Visitation, and more consistent visitation in particular, is associated with less prison misconduct.

Conclusions

Visitation may reduce inmate misconduct. Implications for future research, theory, and policy are discussed.  相似文献

Research suggests that child maltreatment predicts juvenile violence, but it is uncertain whether the effects of victimization persist into adulthood or differ across gender. Furthermore, we know little about the mechanisms underlying the victim-perpetrator cycle for males and females. Consequently, this study analyzed associations between child maltreatment and a number of adult measures of violent offending within mixed-gender and gender-specific models. Along with main effects, the study directly tested the moderating effects of gender on the maltreatment-violence link and analyzed theory-informed gender-specific mediators. Data were derived from the Chicago Longitudinal Study, a panel investigation of 1,539 low-income minority participants born in 1979 or 1980. Child welfare, juvenile court, and criminal court records informed the study's explanatory and outcome measures. Prospectively collected covariate and mediator measures originated with parent, teacher, and self-reports along with several administrative sources. Results indicated that child maltreatment, ages 0 to 11, significantly predicted all study indicators of violence in the full sample and most study outcomes in the male and female subsamples. In no instance did gender moderate the maltreatment-violence association. Late childhood/early adolescence environmental instability, childhood externalizing behaviors, and adolescent peer social skills fully mediated the maltreatment-violence nexus among males. Adolescent externalizing behavior partially mediated the relationship of interest among females. Evidence also indicated that internalizing processes protected females who had been maltreated in childhood against perpetrating violence later in life. Implications of results are discussed.  相似文献

Research Summary
We conducted a Campbell systematic review to examine the effectiveness of problem-oriented policing (POP) in reducing crime and disorder. After an exhaustive search strategy that identified more than 5,500 articles and reports, we found only ten methodologically rigorous evaluations that met our inclusion criteria. Using meta-analytic techniques, we found an overall modest but statistically significant impact of POP on crime and disorder. We also report on our analysis of pre/post comparison studies. Although these studies are less methodologically rigorous, they are more numerous. The results of these studies indicate an overwhelmingly positive impact from POP.
Policy Implications
POP has been adopted widely across police agencies and has been identified as effective by many policing scholars. Our study supports the overall commitment of police to POP but suggests that we should not necessarily expect large crime and disorder control benefits from this approach. Moreover, funders and the police need to invest much greater effort and resources to identify the specific approaches and tactics that work best in combating specific types of crime problems. We conclude that the evidence base in this area is deficient given the strong investment in POP being made by the government and police agencies.  相似文献

The purpose of this study was to collect data and disseminate trends in officer‐involved firearm deaths in Oklahoma from 2000 to 2015. The Oklahoma Office of the Chief Medical Examiner (OCME) database was searched for civilian decedents with gunshot wounds inflicted by law enforcement officers and officer decedents with gunshot wounds inflicted by civilians. Five decedents were law enforcement officers, while 274 decedents were civilians. The number of civilian decedents throughout the study followed a quadratic trend. Civilian decedents were most commonly males (95%) between the ages of 20 and 39 (64%), had one or two gunshot wounds (46%), and had an increasing number of gunshot wounds over time. Postmortem toxicology testing most commonly detected ethanol, methamphetamine, cocaine, and PCP. Efforts toward increased tracking by various agencies and more scientific studies like this are needed to facilitate future analysis of trends in officer‐involved firearm deaths.  相似文献

Objectives

This study presents an outcome evaluation of the Value-Based Therapeutic Environment model, a multipurpose, cognitive–behavioral treatment approach for juvenile offenders.

Methods

Using a quasi-experimental design, the impact of VBTE treatment on recidivism is assessed for 258 youths, relative to a matched subsample of 258 comparison subjects.

Results

Results indicate that VBTE treatment is an effective intervention for reducing violent recidivism but has no significant effect on property, drug, or public order offenses. Consistent with past research, offender type moderates the impact of treatment. Specifically, 72.8 % of high-risk/need youth in the comparison group had reoffended within a 16-month follow-up period, compared to only 57.5 % of high-risk/need MHC youth, yet there were no significant differences between the treatment and comparison groups among low- and medium-risk/need juveniles. Moreover, the odds of a new violent charge were 49 % lower for high-risk/need MHC youth during the 12 months following MHC-discharge. Supplementary analysis indicates that VBTE participants also showed improvements on value- and skills-based behaviors related to self-image, goal orientation, honesty, empathy, decision-making, and personal development.

Conclusions

Findings of this study suggest that the VBTE model is a promising approach for the treatment of violent behavior among high-risk youth. Implications of the findings are discussed with regard to alternative treatment approaches for juvenile offenders.

Ochronosis is the blue‐gray discoloration of collagen‐containing tissues due to homogentisic acid (HGA) deposition, secondary to endogenous alkaptonuria or exogenous enzyme inhibition. In renal disease, accumulation of HGA in serum can cause methemoglobinemia. A 60‐year‐old woman with renal disease and anemia presented with 3 days of weakness and months of gray skin discoloration. Her hemoglobin was 8.1g/dl with 24.5% methemoglobin. Despite treatment with methylene blue, exchange transfusion, and continuous renal replacement therapy, the patient died. Autopsy revealed gray discoloration and ochronotic pigment in the ribs and cartilage. Based on these findings, the patient was diagnosed with ochronosis, suggestive of alkaptonuria, complicated by methemoglobinemia. The differential diagnosis for blue‐gray skin discoloration includes argyria, methemoglobinemia, and ochronosis. This patient's clinical and autopsy findings suggested alkaptonuria complicated by methemoglobinemia due to progressive renal dysfunction. Development of methemoglobinemia in the setting of chronic skin discoloration and renal failure should prompt consideration of alkaptonuria.  相似文献

This study tests the effect of three common oxidizing cleaners on the ability of the Bluestar Forensic® presumptive test for blood to identify the presence of blood on ceramic tile after cleaning. The cleaners tested were Lysol®, OxiClean®, and Arm & Hammer®. This study also tested which cleaner was the most effective at removing blood, measured by the intensity of chemiluminescence, which was quantified using RGB values in ImageJ. A “hasty” 1‐min cleaning of a blood droplet was simulated using the three cleaners. The chemiluminescence of the Bluestar® reactions after cleaning the blood‐treated region was compared to an untreated region of the same tile for each cleaner, as well as to the treated regions of tiles between the three cleaners. Results indicate that none of the three cleaners removed all of the blood (all < 0.001) and that Lysol® removed more blood compared to the OxiClean® and Arm & Hammer®.  相似文献

Henry G. Manne, our friend, Mentor, and colleague, was a pioneer in the economic analysis of law. By consistently challenging the notion that existing institutions were well understood, he expanded the domain of economics to new and fertile ground. In that spirit, our goal in this article is to bring out of the shadows an institution that has thus far evaded the light of economic analysis: antitrust consents. In our view, competition authorities around the world should be asking themselves what ratio of litigation to settlement is optimal for their agency. Over the last 35 years, the United States Federal Trade Commission and the Antitrust Division of the Department of Justice have shifted dramatically toward greater reliance upon consent decrees than upon litigation to resolve antitrust disputes. As an aid to national competition agencies considering the desirability of adopting a similar approach, we focus upon the importance of economic analysis in evaluating movement along the continuum from a law enforcement model to a regulatory model of agency behavior. We draw upon the U.S. experience to substantiate our claim that the costs associated with a shift toward the regulatory model, including the potential distortion in the development of substantive antitrust doctrine, may be under-appreciated and discernable only in the long run. We acknowledge that consent decrees can and should be an important tool in an antitrust agency’s toolkit for resolving antitrust disputes. We contend, however, that a full economic analysis of reliance primarily upon consent decrees is necessary to inform each competition agency’s strategic decision about the optimal mix of law enforcement and regulatory techniques.  相似文献

A recent Australian Federal Court decision has raised the issue of the scope of information protected under the Australian Privacy Act 1988. The Court failed to adequately address this question, leaving Australians unsure as to whether sections of their information, such as the IP addresses allocated to their mobile devices, will be considered personal information under the Act. The main consideration the Court dealt with was what it means for information to be “about” an individual. In this paper I address two questions: a) how is information determined to be “about” an individual under the Act; and b) how should this determination be made in the future? I conclude that currently available guidance from the courts, the Australian Information Commissioner and scholarly commentary are inadequate to enable individuals, organisations and agencies to consistently make such determinations. Accordingly I draw on approaches to this question taken in Canada, New Zealand, the European Union and the United Kingdom to argue that the definition should be broadly interpreted in a technologically-aware manner. This will help to ensure that personal information is more comprehensively protected under the Privacy Act.  相似文献
