Victimization and fear of crime in an entertainment district crime “hot spot:” A test of structural-choice theory

Theories of criminal opportunity and criminal victimization (lifestyles, routine activities, and structuralchoice) all stress the convergence of motivated offenders, suitable targets, and the absence of guardianship in time and space. They each assert the chances of victimization increase as proximity to motivated offenders, exposure to highrisk environments, target attractiveness, and ineffective guardianship increase. This study tests Miethe and Meier’s structuralchoice theory by examining domainspecific victimization and fear of crime among patrons of an entertainment district crime “hot spot. ”Regression results show both victimization experience and fear of crime are associated significantly with indicators of proximity and guardianship, but not with exposure or target attractiveness. White patrons of this area are more likely to be victimized, nonwhites report significantly higher levels of fear.

“To develop and test:” The inventive difference between evaluation and experimentation

The National Research Council (NRC) Report on Improving Evaluation of Anticrime Programs raises a fundamental question about the mission of evaluation research. The implicit premise of the report is that the mission of evaluation is to answer questions about programs developed by others; in short, to test anti-crime programs. In contrast, the mission of experimental criminology has, historically, been to develop anti-crime programs as well as to test them. There are times when an arm’s-length relationship between program and evaluation may be appropriate. Yet, such a separation necessarily produces a courtroom-like adjudication role for evaluators, rather than the laboratory-like, participant–inventor role that has characterized the best of experimental criminology. The recent case of the Chicago police’s “evaluating” the use of sequential suspect identification methods developed by academic psychologists shows the many flaws of the “testing-only” model. This suggests that providing “effective guidance of criminal justice policy and practice,” as the NRC report defines its focus [Lipsey, M. ed (2005). http://newton.nap.edu/pdf/0309097061/pdf_image/R1.pdf] will not only require evaluation research (defined as arm’s-length testing) but the full toolbox of experimental criminology to develop and test anti-crime programs.

Effects of face-to-face restorative justice on victims of crime in four randomized,controlled trials

The growing use of restorative justice provides a major opportunity for experimental criminology and evidence-based policy. Face-to-face meetings led by police officers between crime victims and their offenders are predicted to reduce the harm to victims caused by the crime. This prediction is derived not only from the social movement for restorative justice, but also from the microsociology of interaction rituals (Collins, 2004). Four randomized, controlled trials of this hypothesis in London and Canberra, with point estimates disaggregated by gender, tested the prediction with measures of both successful interaction ritual (apologies received and their perceived sincerity) and the hypothesized benefits of the ritual (on forgiveness of, and reduced desire for violent revenge against, offenders, and victim self-blame for the crime). The meta-analyses of the eight point estimates suggest success (as victims define it) of restorative justice as an interaction ritual, and as a policy for reducing harm to victims.     

Testing hot-spots police patrols against no-treatment controls: Temporal and spatial deterrence effects in the London Underground experiment

Our understanding of causality and effect size in randomized field experiments is challenged by variations in levels of baseline treatment dosage in control groups across experiments testing similar treatments. The clearest design is to compare treated cases with no-treatment controls in a sample that lacks any prior treatment at baseline. We applied that strategy in a randomized test of hot-spots police patrols on the previously never-patrolled, track-level platforms of the London Underground (LU). In a pretest–posttest, control-group design, we randomly assigned 57 of the LU's 115 highest crime platforms to receive foot patrol by officers in 15-minute doses, 4 times per day, during 8-hour shifts on 4 days a week for 6 months. The effect of 23,272 police arrivals at the treatment hot spots over 26 weeks was to reduce public calls for service by 21 percent on treated platforms relative to controls, primarily when police were absent (97 percent of the measured effect). This effect was six times larger than the mean standardized effect size found in the leading systematic review. This finding provides a benchmark against the baseline counterfactual of no patrol in hot spots, with strong evidence of residual deterrence and no evidence of local displacement.     

Abusive Pediatric Thoracolumbar Fracture Due to Forced Hyperextension: Case Report,Biomechanical Considerations,and Review of the Literature

Pediatric thoracolumbar fractures are rare due to the physiological differences which afford greater resilience to the immature spine. Most pediatric thoracolumbar fractures occur as the result of high energy trauma, such as motor vehicle accidents, and modes of reasonable accidental injuries are limited by age and developmental capabilities of the child. These fractures can occur as the result of inflicted blunt force trauma and child abuse, and in most cases, the mechanism of injury to the spine is not known. We report the death of a 29-month-old man due to blunt force trauma to the back and forced hyperextension of the thoracolumbar spine causing fracture of the fourth lumbar (L4) vertebral body. A complete forensic examination revealed a previous healing fracture of the anterior aspect of the L4 vertebral body, with acute disruption of the anterior longitudinal ligament overlying the fracture site, complete fracture of the vertebral body, and fatal retroperitoneal hemorrhage. We present a review of the biomechanical considerations of the pediatric spine, a survey of pediatric spinal fractures, and a review of the literature on pediatric abusive thoracolumbar fractures. In this case, there was never a provided explanation for how the injury occurred; however, understanding the biomechanics of the pediatric spine allowed for the determination of the mechanism, force required to produce this specific pattern of abusive spinal injury, and the manner of death.     

Opportunity,motivation, and assaults on police: A bivariate arima analysis

Drawing on insights garnered from the routine activity and pluralistic conflict perspectives, the present investigation examines the interrelationships between structural sources of opportunities and motivations to engage in potentially conflictive interactions with police personnel and assaults against the police. Overall, the longitudinal analyses of the reciprocal relationship between total and disaggregated measures of arrest and non-lethal assaults within Oklahoma City, Oklahoma tend to produce weak and insignificant results. The implications of these findings for opportunity theories of crime are discussed.
