Reconsidering the relationship between alcohol and lethal violence

Prior event-based research regarding the relationship between alcohol and violence suffers from important limitations, including the absence of a comparison group, an inappropriate comparison group, or a comparison group that could be considered appropriate but does not control for potential confounders. To overcome such limitations, we use a matched pair design. Drawing on interviews with men imprisoned for an aggravated assault or homicide committed in response to a conflict with another man, we examine matched pairs of violent and nonviolent conflicts nested within respondents. The results suggest that guns mediate the relationship between alcohol and lethal male-male violence.     

Four novel alkyl 2-cyanoacylate monomers and their use in latent fingermark detection by mid-infrared spectral imaging

Four novel alkyl 2-cyanoacrylate monomers (alkyl=1-cyanoethyl, 2-cyanoethyl, trideuteromethyl and pentadeuteroethyl) have been tested for their ability to develop latent fingermarks that can then be visualized using mid-infrared spectral (chemical) imaging. Each of the four monomers was chosen for its potential to produce a strong, isolated infrared spectral band in its corresponding polymer (to provide spectral contrast against most backgrounds), as well as for its potential ability to be fumed onto fingermarks in the manner of conventional ethyl 2-cyanoacrylate (superglue). With the exception of the 2-cyanoethyl 2-cyanoacrylate, which had to be fumed under reduced pressure, all of the monomers were found to be sufficiently volatile to be fumed in a conventional fuming cabinet. All four monomers polymerized selectively on fingermark ridges on a variety of non-porous and semi-porous surfaces, leading to excellent development of the fingermarks. Unfortunately, although high quality mid-infrared spectral images of the fingermarks could be formed for all of the polymers at various frequencies, the new CN or CD stretching vibrations did not give rise to strong enough absorption intensities for good contrast on difficult backgrounds such as polymer banknotes. However, in the 1-cyanoethyl 2-cyanoacrylate polymer, the presence of the additional nitrile group had the unintended but desirable effect of shifting the strong CO absorption to higher frequencies, moving it away from interfering banknote absorptions. This enabled fingermark contrast to be achieved even against the intaglio printing on the banknotes.     

Judges’ Perceptions of Screening,Assessment, Prevention,and Treatment for Substance Use, Mental Health,and HIV among Juveniles on Community Supervision: Results of a National Survey

Juvenile Justice‐Translational Research on Interventions for Adolescents in the Legal System (JJ‐TRIALS) National Survey was funded in part to describe the current status of screening, assessment, prevention and treatment for substance use, mental health, and HIV for youth on community supervision within the US juvenile justice system. Surveys were administered to community supervision agencies and their primary behavioral healthcare providers, as well as the juvenile or family court judge with the largest caseload of youth on community supervision. This article presents the findings from the judges’ survey. Survey results indicated juvenile and family court judges were open to innovations for improving the court's performance, rated their relationships with collaborators highly, and appreciated the impact of screening, assessment, prevention, and treatment on judicial practices.     

Alcohol-related crime among college students: a review of research and fruitful areas for future work

College and alcohol are a potent mix. This paper reviews what is known and unknown about college students’ involvement in alcohol-related crime as both offenders and victims. There are three types of alcohol-related crime: psychopharmacological; economic compulsive; and systemic. Research on college students, however, has focused entirely on the first type. Why are the latter two types untouched in the literature? After reviewing research on alcohol-involved psychopharmacological crime among college students, we address this question by drawing on Lewis & Lewis’ taxonomy of ‘negative evidence.’ We outline and assess reasons for the dearth of information on these topics, and draw on these explanations to suggest fruitful areas for future research.     

Are old witnesses always poorer witnesses? Identification accuracy,context reinstatement,own-age bias

Abstract

Anecdotal evidence suggests that it is unwise for a criminal defense lawyer to allow a law enforcement officer, former law enforcement officer, or relative/close friend of an officer to serve as a juror. This project examined the decisions of 2853 jurors of whom 235 reported being or having been a law enforcement officer and 1348 reported knowing a close friend or relative who is or was an officer. Participants watched a videotape of a trial of a burglary of a habitation and were asked to give individual verdicts. Results indicated that the average conviction rate was 57.6%. Past and present officers did not differ in their conviction rate from non-officer jurors. Jurors who indicated knowing a past or present law enforcement officer did not convict the defendant more than those who did not know anyone in law enforcement. Implications for this research are discussed.
