A Novel Method for Removing a Spinal Cord with Attached Cervical Ganglia from a Pediatric Decedent

A diagnosis of child abuse is dependent on a comprehensive and accurate assessment of injury in the context of a thorough investigation. However, signatures of trauma are often subtle and interpretation can be very difficult. Recently, researchers have refocused their attention from the head to the neck in search of traumatic signatures of abusive head trauma. HCIFS has developed a technique to remove the cervical spinal cord with the ganglia attached that is less destructive and more time and cost efficient than alternative methods previously published. Once removed, the dorsal nerve roots and ganglia are evaluated for the presence of hemorrhage. The authors performed a small pilot study using the novel method to evaluate 20 decedents with a history of blunt force trauma and eight without a traumatic history. Fifteen of the traumatic deaths and two of the nontraumatic deaths were found to have dorsal nerve root and/or ganglia hemorrhage.     

The Conditioning Effects of Race and Gender on the Juvenile Court Outcomes of Delinquent and “Neglected” Types of Offenders

Drawing upon concepts from prior research that emphasize race and gender stereotyping, the present research compares how delinquent and “neglected” types of offenses (i.e. status offenses, probation violations, youth charged with contempt) are treated across three juvenile court outcomes. Beyond how offense type may directly impact case outcomes, we also investigated whether race and gender influenced juvenile justice processing within each offense type. Using data from two Mid-Atlantic States, results indicated that type of offense, race, and gender resulted in both severe and lenient case outcomes depending on the stage examined. By including different types of offenses that represent a significant percentage of youth that have been relatively neglected in prior research, the current study provides greater insight into the contexts of race and gender disparities in juvenile justice decision-making. The implications of the findings and directions for future research are also discussed.     

A meta-analysis update on the effects of early family/parent training programs on antisocial behavior and delinquency

Objective

To update Piquero et al.’s meta-analysis on early family/parent training programs.

Methods

Screening of eligible studies was carried out for the period between January 2008 and August 2015. An additional 23 studies were identified, which were added to the original database of 55 studies, totaling an overall sample of 78 eligible studies. A random-effects model was used to obtain an overall mean effect size estimate. Additional analyses were performed to assess publication bias and moderation.

Results

An overall average, positive, and significant effect size of 0.37 was calculated, which corresponds to 32 out of 100 in a treated group versus 50 out of 100 in a control group who offended. There was some evidence of publication bias and moderation.

Conclusions

Early family/parent training programs are an effective evidence-based strategy for preventing antisocial behavior and delinquency.

     

A meta-analysis update on the effectiveness of early self-control improvement programs to improve self-control and reduce delinquency

Objective

To update Piquero et al.’s (Justice Quarterly 27:803–834, 2010) meta-analysis on early self-control improvement programs.

Methods

Screening of eligible studies was carried out for the period between January 2010 and September 2015. An additional seven studies were identified, which were added to the original database of 34 studies, totaling an overall sample of 41 eligible studies. A random effects model was used to obtain an overall mean effect size estimate. Additional analyses were performed to assess publication bias and moderation.

Results

Overall average, positive, and significant effect sizes were observed for improving self-control (0.32) and reducing delinquency (0.27). There was evidence of publication bias for the self-control improvement outcomes, as well as some evidence of moderation for both self-control improvement and delinquency outcomes.

Conclusions

Early self-control improvement programs are an effective evidence-based strategy for improving self-control and reducing delinquency.

     

Four Principles of Big Data Practice for Effective Child Welfare Decision Making

Large administrative data systems are powerful tools that can aid child welfare decision making by allowing populations, trends, and risks to children to be described. But realizing the value that this “big data” can bring to improving the lives of children and their families requires one to (a) start the process by asking a question, (b) take a disciplined approach to converting data to evidence, (c) commit to the cyclical process of improvement using evidence, and (d) arrange and analyze the data in ways that maximize evidence yield. This article describes how these four principles can help agencies and researchers use big data wisely and in accordance with scientific standards as an instrument to generate evidence that fuels the cycle of continuous quality improvement.     

Prevalence of xylazine in overdose cases: An analysis of Miami-Dade County medical examiner case data

Xylazine sedative, muscle relaxant, and analgesic used in a veterinary setting. Although xylazine was never approved for therapeutic use in humans, it has become popular in the street drug market as a cutting or bulking agent in the fentanyl and heroin supply. Recently, there has been a significant increase in the detection of xylazine in postmortem forensic toxicology casework. Xylazine can be identified during routine toxicology screening utilizing instrumentation such as gas chromatography–mass spectrometry and liquid chromatography–mass spectrometry. Using the Miami-Dade Medical Examiner's LIMS system, all cases received between 2015 and 2022 in which xylazine was reported were reviewed. The cases studied include accidental drug overdose deaths in Miami-Dade County as well as Collier County (Naples), Florida. In total, there are 170 cases; the majority are accidental polydrug overdoses involving White males between the ages of 25 and 44 years old. Of the 170 cases, 37% listed xylazine as the cause of death. 13% of cases contained only xylazine and fentanyl while the remaining 87% of deaths were attributed to polydrug toxicity involving two or more substances. The prevalence of xylazine can be attributed to its increasing popularity rather than an increase in caseload. In 2019, xylazine was present in only 4% of all accidental fentanyl overdoses. By 2021, this percentage has increased sixfold, with xylazine present in 24% of all accidental fentanyl overdoses. Despite a decrease in fentanyl overdoses in 2022, the percentage of xylazine detection remained the same.     

Diversifying the police applicant pool: motivations of women and minority candidates seeking police employment

Given the media attention to police killings of unarmed men of color, police agencies have increased their focus on the diversity of their applicant pools. Despite their efforts, policing leaders across the United States have cited challenges in recruiting a diverse police force and are exploring evidence-based solutions. However, the bulk of the literature on motivation to seek a career in policing is dated and includes small samples of women and minority respondents. The purpose of this study is to provide contemporary insight into reasons of women and minority candidates for applying to a police department. Thus, this study focuses on women and minority applicants to a large policing agency in the northeastern United States, asking respondents an open-ended question about their motivation to apply. Policing as a childhood dream, making a difference in the community and the opportunity to help people, and believing policing was a good transition from military to civilian life were the most commonly cited reasons for applying. Salary, benefits and job security were the least cited reasons for applying for a police position. Other findings and policy implications are discussed.

The Crime and Threat Image Set (CaTIS): a validated stimulus set to experimentally explore fear of crime

Objectives

Fear of crime may develop in response to crime specifically (the narrow pathway) or may be a projection of broader threats (the broad pathway). New approaches are needed to examine how crime and threat, independently and in combination, influence people’s fear. To address this need, we created, evaluated, and validated an image set that varied across the dimensions of threat and crime.

Method

We used a 2 (Threat: high vs. low) × 2 (Crime: high vs. low) within-subjects factorial design. In three studies, participants (N = 24, 29, and 176, respectively) gave threat, crime, and fear ratings towards images. Participants also completed two traditional fear of crime measures and a measure of anxiety. Two evaluation studies explored the suitability of 178 images to produce a final set of 80 images (20 in each of the four categories). We validated this final set of 80 images in a third study.

Results

The validated Crime and Threat Image Set (CaTIS) contains 78 images across four categories: threat-and-crime (high-crime, high-threat), threat-only (low-crime, high-threat), crime-only (high-crime, low-threat), and neutral (low-crime, low-threat). There were significant main effects of threat and crime, and an interaction between Threat × Crime, on participants’ fear ratings. Participants’ own ratings of threat—but not crime—had a strong relationship with their fear ratings.

Conclusions

Threat had a stronger influence on participants’ fear ratings than crime. Thus, what is typically referred to as fear of crime may reflect broader fear. Further research with the CaTIS could explore the expression of this fear.
