Enhancing Data-Driven Law Enforcement Efforts: Exploring how Risk Terrain Modeling and Conjunctive Analysis Fit in a Crime and Traffic Safety Framework

Law enforcement’s examination of vehicle crashes is often nested in the Data-Driven Approaches to Crime and Traffic Safety (DDACTS) framework which highlights the importance of hot spot analysis. To assist law enforcement efforts, this study explores how two additional spatial techniques, namely risk terrain modeling (RTM) and conjunctive analysis of case configurations (CACC), could be incorporated within the DDACTS framework. RTM was utilized to identify how the built, physical environment contributed to the risk of traffic incidents. RTM identified 6 risk factors related to the occurrence of vehicle crashes, and high-risk places were compared to hot spots on predictive accuracy. CACC was used to explore configurations likely to result in traffic incidents for the priority places. Our findings support the Theory of Risky Places and fit within a vulnerability-exposure framework, providing law enforcement with guidance for identifying places where vehicle crashes are likely to occur in the future. In addition to providing insight for law enforcement, we discuss how law enforcement can develop working partnerships with stakeholders capable of preventing and/or reducing traffic incidents, which is in line with the general DDACTS framework.

     

Stability of life-time psychiatric diagnoses among offenders in community and prison settings

The dearth of studies investigating diagnostic stability among offenders, and diagnostic stability being important from the patient’s mental health perspective, as well as from a public health, training and research standpoint, highlights the need to evaluate lifetime stability of ICD-10 psychiatric diagnoses for offenders in community and prison settings. A case-linkage design linked a two-year population-based cohort of male-sentenced prisoners with a state-wide psychiatric register (23,742 psychiatric consultations). Four measures of diagnostic stability were calculated for each setting as well as across settings, for all offenders who received at least two psychiatric diagnoses. Temporal consistency was moderate for schizophrenia spectrum disorders and low for affective, anxiety and personality disorders, and was higher in prison setting than community settings. Diagnostic instability highlights that the course of mental illness and clinical features among offenders may genuinely vary over time, across community and prison settings and may lead to complexities regarding psychiatric care for this population     

Substance use among African American adolescents in the Midwest

The purpose of this article is to examine the attitudes and substance use behaviors of African American adolescents living in the Midwest. A baseline survey was administered to 463 African American teens between the ages of 11-19. The article examines the relationship between attitudes toward drugs and drug-using behavior in this African American sample. Drug use will be compared to national drug use norms established by the Youth Risk Behavior Surveillance Survey. Overall participants had fairly negative attitudes toward drugs. Sixty percent of the sample reported that they were committed to a drug-free life, 74% had made a decision to stay away from marijuana, 79% reported making a decision not to smoke cigarettes, and 71% reported they would not get drunk in the next year. Females were more likely to stay away from marijuana than males. In this current study there is cause for alarm; participants reported higher percentages of ever smoking cigarettes and marijuana than the Youth Risk Behavior Surveillance Survey. This study shows there is a need to provide substance abuse prevention programs for African American adolescents. Limitations and future directions are also discussed.     

A look from the inside: balancing custody and treatment in a juvenile maximum-security facility

This article is based on an ethnographic study of a cottage for violent offenders in one state's maximum-security training school. Staff members working in the cottage were the institution's front line in its attempts to hold the youth accountable for their crimes while also trying to resocialize and rehabilitate young men who were growing up with few conforming role models. As such, cottage staff members were put in the difficult position of juggling their roles as corrections officers, counselors, and surrogate parents. To effectively do their job, they had to find ways to balance the rhetoric of rehabilitation with the punitive reality of daily life in the institution. This article details the juvenile justice career paths of the staff members in the cottage and provides a sociological analysis of the roles, responsibilities, and interactions of the staff members with each other and with the young men in their care.     

Comparison of motor oils using high-temperature gas chromatography-mass spectrometry

The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data.     

The Effect of Vertebral Numerical Variation on Anatomical Stature Estimates

Abstract: Most humans possess 24 presacral vertebrae composed of seven cervicals, 12 thoracics, and five lumbars. However, variation from this standard pattern exists. The purpose of this study was to test the effect of congenital vertebral numerical variation on anatomical stature estimates and to recommend appropriate procedures when such variation occurs. Our sample consists of 41 individuals with unusual vertebral count patterns and known cadaveric statures from the Smithsonian’s Terry Collection. Raxter et al. published a revised Fully anatomical technique in 2006 and we used this to estimate living stature. Based on our results, we recommend using the standard anatomical technique to reconstruct stature, regardless of vertebral pattern. However, when an individual possesses six sacral segments together with a normal number of presacral vertebrae, we recommend the addition of a slight correction factor of 1.3 cm or 0.8% of estimated stature.     

Serving the creditors after insolvency filings: from value creation to value distribution

This paper provides original empirical evidence on the financial outcome of insolvency filings in Europe. We adopt a cross-country analysis of the determinants of recovery rates isolating three types of creditors (junior, senior, and new money claims). We investigate the structure of recoveries on a unique hand-collected sample of bankrupt firms in France, Germany, and the UK. We initially question value maximization, and study to which extent the legal provisions prevailing after insolvency filing can influence creditors’ overall recoveries. Three procedures differ significantly from our benchmark (UK liquidations). French continuation and UK receivership exert a positive influence onto total repayments, while such influence becomes negative under French liquidation. We relate this finding to the ability of the two former procedures to improve coordination among the creditors, monitoring of the debtor, and/or incentives to file early. We then analyze value distribution by examining competition between the categories of creditors. We show that the insolvency systems do not converge. Junior and senior creditors are better served under the German and the French continuation procedures than in any other bankruptcy path. At the opposite, the UK liquidation procedures fail to satisfactorily serve the junior/senior creditors. Still, nearly all the insolvency procedures support fresh financing by protecting quite well new money claims. Overall, we do not confirm any superiority of one family of insolvency system over another, but rather stress the importance of an appropriate design of the procedures, especially regarding the incentives they create before and after insolvency filing.     

Examining the demographic profile and attitudes of citizens,in areas where organized crime groups proliferate

Whilst studies refer to the community impact of Organized Crime (OC), no survey currently exists to examine the views of those citizens who reside in areas where Organized Crime Groups (OCGs) proliferate. 431 questionnaires from households co-existing in high density OCGs areas were analysed in relation to: a) demographic information; b) views on the community and the police; and c) how they expected other residents to react to illegal incidents. Overall respondents thought the average citizen would refuse to intervene in 10% - 48% of illegal incidents, with the specific case influencing whether and how they would respond. The analysis then compared three communities who lived in high density OCG areas with a control community (n?=?343). The ‘OCG’ communities were more likely to report low collective efficacy and were generally least likely to expect their neighbours to confront a crime in action. Conversely, whilst the control group showed higher levels of collective efficacy and expected the average resident to be more likely in confronting illegal behaviour, this trend did not extend to street drug dealing and serious crime associated with OC. The study discusses the unreported intimidation associated with OCGs and the challenges of policing hostile environments.     

Are jurors' perceptions of eyewitness credibility affected by the cognitive interview?

Abstract

Ninety-one college subjects listened to Cognitive Interviews (CI) and Standard police interviews of 7-year old children who were attempting to describe an earlier incident of playing a game of Simon Says. The subjects evaluated the witness's credibility and also the interviewer's manipulativeness. The perceived credibility of the witness was not affected by the type of interview, i.e., the CI did not render the witness unduly credible. In addition, the CI interviewer was judged to be less manipulative than the Standard police interviewer. These results were discussed in light of some potential legal concerns about using the CI.
