Development of a Protein‐based Human Identification Capability from a Single Hair

Shed human hair (lacking root nuclear DNA) frequently contributes important information to forensic investigations involving human identification. Detection of genetic variation observed in amino acid sequences of hair proteins provides a new suite of identity markers that augment microscopic hair analysis and mitochondrial DNA sequencing. In this study, a new method that completely dissolves single hairs using a combination of heat, ultrasonication, and surfactants was developed. Dissolved proteins were digested and genetically variant peptide (GVP) profiles were obtained for single hairs (25 mm) via high‐resolution nanoflow liquid chromatography‐based mass spectrometry and a novel exome‐driven bioinformatic approach. Overall, 6519 unique peptides were identified and a total of 57 GVPs were confirmed. Random match probabilities ranged between 2.6 × 10^?2 and 6.0 × 10^?9. The new bioinformatic strategy and ability to analyze GVPs in forensically relevant samples sizes demonstrate applicability of this approach to distinguish individuals in forensic contexts.     

Testing the three- and four-factor models of the Korean version PCL-R as predictors of two antisocial outcomes – recidivism and risk

Psychopathy has consistently been associated with antisocial outcomes. The three- and four-factor models have been best fitted to data relating to Korean serious offenders (N?=?451), offering construct validity of the Korean Psychopathy Checklist-Revised (PCL-R). However, no study has yet tested the predictive power of the Korean PCL-R to explain two different types of antisocial outcomes: (1) risk of inmates measured by correctional officers during incarceration and (2) recidivism after release. By exploring these two forms of antisociality, here we sought to establish the predictive and construct validities of the Korean version of PCL-R. We found that the deviant lifestyle (Factor 3) performed best for predicting both antisocial forms (risk and recidivism) and that the deficits in interpersonal (Factor 1) and affective (Factor 2) abilities also uniquely predicted one subtype of risk, which suggests the three-factor model is better than the four-factor model in predictions. These findings will be useful for criminal justice experts and practitioners in Korea.     

Evaluating the Juvenile Breaking the Cycle Program's impact on recidivism

This article presents findings from an evaluation of the Juvenile Breaking the Cycle (JBTC) Program, an intervention that was designed to provide criminal justice system monitoring and individualized treatment and services to substance-using youth who were assessed as high recidivism risks following an initial police encounter. Results from logistic and negative binomial regression models, using repeated data measures, indicated that JBTC participants, relative to baseline and a sample of comparison youth, were significantly less likely to be arrested and had significantly fewer arrests in the six to twelve months after entering the program. The JBTC Program appears to be one that jurisdictions should consider replicating in an effort to address the needs of juveniles who are at risk for delinquency and substance use in their communities.     

FAMILY COURT–UNIVERSITY PARTNERSHIP TO BENEFIT DIVORCING FAMILIES: THE EXPERIENCE OF MARICOPA COUNTY (ARIZONA) FAMILY COURT DEPARTMENT AND ARIZONA STATE UNIVERSITY'S PREVENTION RESEARCH CENTER*

Using evidence‐based methods to help divorcing families requires the combined best efforts of legal professionals, courts, judges and administrators, mental health oriented service providers, and university researchers. Collaborative program development, implementation, and evaluation involve a complicated process of negotiation between professionals, yet this process is hardly ever described. The current article describes the processes we underwent in forging an alliance of researchers from Arizona State University's Prevention Research Center with professionals from the Maricopa County (Arizona) Family Court, a collaboration that involved a true dialogue and cooperation from the earliest stages and continuing throughout the project. A Community‐Based Participatory Research model was the underlying basis for our partnership; its lynchpin device was a Joint Planning Committee.     

Testing Antemortem Blood for Ethanol Concentration from a Blood Kit in a Refrigerator Fire

The stability of ethanol in antemortem blood stored under various conditions has been widely studied. Antemortem blood samples stored at refrigerated temperature, at room temperature, and at elevated temperatures tend to decrease in ethanol concentration with storage. It appears that the stability of ethanol in blood exposed to temperatures greater than 38°C has not been evaluated. The case presented here involves comparison of breath test results with subsequent analysis of blood drawn at the time of breath testing. However, the blood tubes were in a refrigerator fire followed by refrigerated storage for 5 months prior to analysis by headspace gas chromatography. The subject’s breath was tested twice using an Intoxilyzer 8000. The subject’s blood was tested in duplicate using an Agilent headspace gas chromatograph. The measured breath ethanol concentration was 0.103 g/210 L and 0.092 g/210 L. The measured blood ethanol concentration was 0.0932 g/dL for both samples analyzed. Although the mean blood test result was slightly lower than the mean breath test result, the mean breath test result was within the estimated uncertainty of the mean blood test result. Even under the extreme conditions of the blood kit being in a refrigerator fire, the measured blood ethanol content agreed well with the paired breath ethanol test.     

Policing alienated minorities in divided cities

Minority groups frequently challenge the legitimacy of legal authorities, particularly the police. Without trust and legitimacy, the police encounter constant conflict and cannot function effectively. While past research has examined minorities’ perceptions of the police, national minorities provide an interesting and under‐investigated test case because of their inherent identity conflict with the state. The current research examines three factors to explain minority–majority disparities in views of the police: (i) police effectiveness and fairness; (ii) intergroup discrimination (termed relative deprivation in policing); and (iii) identification with the state. Findings from a survey of Jewish and Arab residents of nationally mixed neighborhoods in Israel (n = 394) suggest that while all of these factors account for minority–majority discrepancies in views of the police, perceptions of police fairness are particularly important. Furthermore, feelings of discrimination and low levels of identification with the state are less important than evaluations of fairness in explaining minorities’ negative perceptions of the police.     

How Managers Can Reduce Household Water Use Through Communication: A Field Experiment

As populations increase and droughts intensify, water providers are using tools such as persuasive messaging to decrease residential water use. However, district-led messaging campaigns are rarely informed by psychological science, evaluated for effectiveness, or strategically disseminated. In collaboration with a water district, we report a field experiment among single-family households using persuasive messaging based on the information-motivation-behavioral skills model (IMB). We randomly assigned 10,000 households to receive different mailings and measured household water use. All messaging reduced water consumption relative to the control. On average, water use dropped 0.68 hundred cubic feet (HCF) (509 gallons) per household in the first month. Had all 10,000 single-family, occupied, non-agricultural residences been mailed the IMB messaging, more than five million gallons would have been saved in the first month. The effects declined but persisted for approximately three months and were three to six times greater in households with high water use (75th to 90th percentiles) relative to average water use. These findings suggest that combining message elements from the IMB model can reduce residential water use and that targeting high-use households is particularly cost-effective.     

On creating ethical,productive, and durable research partnerships with police officers and their departments: a case study of the National Justice Database

ABSTRACT

Translational policing science must begin with explicitly communicated research aims and a shared vision for promoting safety. For researchers to approach police departments without first considering the concerns held by officers and their departments at large, is unethical, unproductive, and undermines efforts to secure longstanding mutually useful researcher-practitioner partnerships. In presenting a case study analysis of the multi-method National Justice Database’s recruitment practices, this article highlights some of the challenges that emerge when articulating study aims that hold relevance for public safety; defining theoretically- and solution-oriented research questions; administrative police data collection, analysis, and dissemination; and bolstering human research subject protection protocols for sworn officers who may be justifiably reluctant to participate in social science research endeavors. Implications for ethical policing research practice, fostering collaborative researcher-practitioner partnerships, and leveraging the benefits of data science are also discussed.
