Juror decision making

Much of the research on juror decision making is concerned with whether jurors are swayed by irrelevant-or extralegal-issues in their judgments of defendants. Such studies examine whether jurors' attitudes and victims' and defendants' characteristics have a measurable impact on these decisions. Yet, in the typical study, evidential issues are either poorly measured or ignored, hence the effects of extralegal issues may be exaggerated. Moreover, jury simulations are often chosen to study these questions despite critics' concerns about the generalizability of the results. The present study uses data gathered from actual jurors to assess whether the emphasis on juror competence is justified. The results indicate that these jurors' decisions are dominated by evidential issues, particularly evidence concerning the use of force and physical evidence. Jurors were considerably less responsive to characteristics of victims and defendants, although some of these factors significantly affected their decisions.The research reported here was supported by the National Institute of Mental Health under grant No. R01 MH29727 and the National Institute of Justice under grant No. 82-IJ-CX-0015.

A cross-cultural examination of adolescent civic engagement: comparing Italian and American community-oriented and political involvement

The purpose of this study was to investigate community-oriented and political civic engagement activities and intentions among youth in Italy and the United States. Adolescents (N = 566) from academically rigorous schools in both countries completed surveys assessing frequency of civic activity participation, motivation for activity, evaluations of activity, and intentions for future civic engagement. Results suggest that youth in both countries were more likely to participate in community-oriented than political civic activities and that youth in both countries found their civic experiences to be meaningful. American youth reported more past civic activities of both types and higher intentions for future community-oriented civic engagement compared to Italian youth. Finally, a model was tested to examine links between peer and school contexts and civic activities and intentions. Findings highlighted that, in both countries, peer and school contexts had a stronger impact on community-oriented than on political civic activity.     

Mitochondrial DNA sequencing of cat hair: an informative forensic tool

Approximately 81.7 million cats are in 37.5 million U.S. households. Shed fur can be criminal evidence because of transfer to victims, suspects, and/or their belongings. To improve cat hairs as forensic evidence, the mtDNA control region from single hairs, with and without root tags, was sequenced. A dataset of a 402-bp control region segment from 174 random-bred cats representing four U.S. geographic areas was generated to determine the informativeness of the mtDNA region. Thirty-two mtDNA mitotypes were observed ranging in frequencies from 0.6-27%. Four common types occurred in all populations. Low heteroplasmy, 1.7%, was determined. Unique mitotypes were found in 18 individuals, 10.3% of the population studied. The calculated discrimination power implied that 8.3 of 10 randomly selected individuals can be excluded by this region. The genetic characteristics of the region and the generated dataset support the use of this cat mtDNA region in forensic applications.     

Trauma and Posttraumatic Stress Disorder Among Substance-Using Women Entering Cook County Jail

In the United States, the number of incarcerated women continues to rise each year, with African American women having the highest incarceration rates. Many women enter prisons and jails with an extensive trauma history, though little is known about the percentage of these individuals suffering from posttraumatic stress disorder (PTSD) and specific trauma exposures they have had based on factors such as homelessness, degree of substance problems, and race. The present study examines a largely African American substance-using population of incarcerated women to determine the impact of various factors on specific traumas reported. We found that individuals reporting symptoms meeting criteria for PTSD had experienced the highest average number of traumas, and those who had ever been homeless also experienced many and varied trauma exposures compared with those who had never been homeless. Higher substance problems were also associated with more trauma exposure. Fewer than 10 percent of the sample met full criteria for PTSD, though those reporting having ever been homeless and those with higher substance problems were significantly more likely to meet all criteria. Results indicate a need to assess previous homelessness as a method for identifying additional trauma exposures and guiding treatment to women's specific needs and trauma profiles.     

Hair-MAP: a prototype automated system for forensic hair comparison and analysis

This paper demonstrates the feasibility of the automation of forensic hair analysis and comparison task using neural network explanation systems (NNESs). Our system takes as input microscopic images of two hairs and produces a classification decision as to whether or not the hairs came from the same person. Hair images were captured using a NEXTDimension video board in a NEXTDimension color turbo computer, connected to a video camera. Image processing was done on an SGI indigo workstation. Each image is segmented into a number of pieces appropriate for classification of different features. A variety of image processing techniques are used to enhance this information. Use of wavelet analysis and the Haralick texture algorithm to pre-process data has allowed us to compress large amounts of data into smaller, yet representative data. Neural networks are then used for feature classification. Finally, statistical tests determine the degree of match between the resulting collection of hair feature vectors. An important issue in automation of any task in criminal investigations is the reliability and understandability of the resulting system. To address this concern, we have developed methods to facilitate explanation of neural network's behavior using a decision tree. The system was able to achieve a performance of 83% hair match accuracy, using 5 of the 21 morphological characteristics used by experts. This shows promise for the usefulness of a fuller scale system. While an automated system would not replace the expert, it would make the task easier by providing a means for pre-processing the large amount of data with which the expert must contend.     

Decide your time: Testing deterrence theory's certainty and celerity effects on substance-using probationers

Background

Bolstered by the initial effectiveness of programs such as Hawaii's Project HOPE, the resurgence in practical applications of deterrence theory has focused on certainty and swiftness of punishment. Following this theoretical trend, Delaware's Decide Your Time (DYT) program was designed to manage high risk substance-using probationers by focusing on the certainty of detection through frequent drug tests and graduated but not severe sanctions.

Objective

This paper, stemming from a larger process evaluation of DYT, reports on the theoretical development and implementation issues involved in instituting such a program in a large, urban probation department.

Methods

Data for the current effort consisted of notes taken at DYT management and staff meetings, interviews with key informants, and observational fieldwork.

Results

The evaluation demonstrated that judicial practices, client eligibility, logistics, and cooperation with secure facilities all posed noteworthy issues for program implementation. Perhaps just as important is the willingness of the program managers to listen to front line officers and make necessary changes to ensure the program's effectiveness and efficiency.

Conclusion

This study suggests that the design of similar programs should carefully consider the local legal structure and the policies and practices of the corrections institutions, treatment providers, and probation department.     

Performance of the Emit® II Plus 6-Acetylmorphine Assay on the Viva-E® analyzer

We evaluated the performance of Emit(?) II Plus 6-Acetylmorphine Assay for human urine screening on the Viva-E(?) analyzer. Precision was evaluated using the cutoff and ±25% controls. Recovery and linearity were studied by spiking 6-acetylmorphine (6-AM) into human urine pools. Accuracy was evaluated using urine specimens and the results were compared to those from GC/MS. Cross-reactivity with structurally related drugs was assessed at different cross-reactant concentrations. Interferences were assessed in the presence of 7.5 and 12.5 ng/mL of 6-AM. The qualitative repeatability coefficients of variation (CV's) ranged from 0.3% to 0.4% and the within-lab CV's ranged from 2.0% to 2.2%. In analyte units (ng/mL), the repeatability CV's ranged from 1.3% to 2.2% and the within-lab CV's ranged from 2.6% to 4.3%. The limit of detection of the assay was found to be 2.1 ng/mL. Recovery was within 15% of expected value. Linearity was 2.1-20 ng/mL. Method comparison showed 99% agreement with GC/MS. The assay had minimal cross-reactivity with morphine, morphine-3-glucuronide, morphine-6-glucuronide and other opioids. No interference was observed with endogenous interferences and structurally unrelated drugs. The assay correctly classified CAP survey samples. The Emit(?) II Plus 6-Acetylmorphine Assay will be a suitable screening method for urine specimens in both qualitative and semi-quantitative analyses.     

Environmental survey for four pathogenic bacteria and closely related species using phylogenetic and functional genes

Bacterial species with high DNA sequence similarity to pathogens could affect the specificity of assays designed to detect biological threat agents in environmental samples. The natural presence of four pathogenic bacteria, Bacillus anthracis, Clostridium perfringens, Francisella tularensis, and Yersinia pestis and their closely related species, was determined for a large collection of soil and aerosol samples. Polymerase chain reaction (PCR) and gene sequencing were used using group-specific 16S rRNA primers to identify pathogens and related species, and pathogen-specific virulence genes. Close relatives of B. anthracis (B. cereus group species) were detected in 37% of the soils and 25% of the aerosol samples. The B. anthracis protective antigen (pag) gene or a close homolog was detected in 16 of these samples. For the other three pathogen groups, the frequency of detection was much lower, and none of the samples were positive with both the phylogenetic and virulence gene primer sets.     

Trends in understanding and addressing domestic violence

This article is a response to three questions posed by the editor about past and future research on interpersonal violence by focusing in this essay on domestic violence:(a) What is the most important thing we have learned about this social problem in the last 20 years, (b) what is the most important thing we need to learn about it in the next 10 years, and (c) what is the most promising methodological innovation in the last 20 years for the study or treatment of domestic violence? This assessment suggests that the field has witnessed considerable advances in domestic violence research and policy but that many as yet untapped opportunities exist to improve both knowledge and practice.     

Ex-offender employment programs and recidivism: A meta-analysis

One consequence of the tremendous growth in the number of persons under supervision of the criminal justice system, whether incarcerated, on parole, or on probation, is the effect of this criminal history on finding and keeping a job. Ex-offenders, especially those recently released from prison, face substantial barriers to many types of legal employment; nonetheless, stable employment is one of the best predictors of post-release success. Thus, policy-makers concerned about high recidivism rates face an obvious need to improve the employment prospects of ex-offenders. Over the last 25 years, many programs that were designed to increase employment (and, by so doing, reduce recidivism) among ex-offenders have been implemented and evaluated. [Wilson, D. B., Gallagher, C. A., Coggeshall, M. B. & MacKenzie, D. L. (1999). Corrections Management Quarterly 3(4), 8–18; Wilson, D. B., Gallagher, C. A. & MacKenzie, D. L. (2000). Journal of Research in Crime and Delinquency 37(4), 347–368] conducted a quantitative synthesis and meta-analysis of 33 evaluations of educational, vocational, and work programs for persons in correctional facilities. To date, however, the evaluation literature on employment programs for those with a criminal record who are not in custody has not been systematically reviewed. This paper presents the results of a quantitative meta-analysis of eight random assignment studies of such programs, using the Campbell Collaboration methodology. The results indicate that this group of community employment programs for ex-offenders did not reduce recidivism; however, the experimental design research on this question is small and does not include some of the promising community employment programs that have emerged in the last decade.
