Numerical classification of curvilinear structures for the identification of pistol barrels

This paper demonstrates a numerical pattern recognition method applied to curvilinear image structures. These structures are extracted from physical cross-sections of cast internal pistol barrel surfaces. Variations in structure arise from gun design and manufacturing method providing a basis for discrimination and identification. Binarised curvilinear land transition images are processed with fast Fourier transform on which principal component analysis is performed. One-way analysis of variance (95% confidence interval) concludes significant differentiation between 11 barrel manufacturers when calculating weighted Euclidean distance between any trio of land transitions and an average land transition for each barrel in the database. The proposed methodology is therefore a promising novel approach for the classification and identification of firearms.     

Differential outcomes of court-supervised substance abuse treatment among California parolees and probationers

To explore the effectiveness of court-supervised drug treatment for California parolees, offender characteristics, treatment experiences, and outcomes were examined and contrasted to those of probationers. The analysis used statewide administrative data on 4,507 parolees and 22,701 probationers referred to treatment by Proposition 36 during fiscal year 2006-2007. Compared with probationers, parolee problems were more severe at treatment entry, more were treated in residential settings, treatment retention was shorter, and fewer completed treatment. Regarding outcomes, fewer parolees were successful at treatment discharge and more recidivated over 12-months post admission. Both groups improved in many areas by treatment discharge, but improvements were generally smaller among parolees. Significant interaction effects indicated that parolees benefited from residential care and more treatment days, even after controlling for covariates. Court-supervised drug treatment for parolees can "work;" however, parolees have more frequent and diverse needs, and their outcomes are enhanced by more intensive treatment. Findings suggest methods for optimizing the effectiveness of criminal-justice-supervised programs for treating drug-dependent offenders.     

Venirepersons’s Attitudes Toward the Insanity Defense: Developing,Refining, and Validating a Scale

Given the prevalence and predictive strength of negative attitudes toward the insanity defense, we conducted three studies with 426 venirepersons to develop an understanding and a measure of public attitudes toward the insanity defense. In these studies, we developed, iteratively refined, and cross-validated the insanity defense attitude-revised (IDA-R) scale. The results suggest that IDAs are underpinned by ones degree of (a) orientation toward strict liability, and (b) concern about perceived injustice and danger associated with the defense. The IDA-R assesses these two-dimensions with good internal consistency, convergent and divergent validity, and predictive utility. The IDA-Rs predictive utility generalizes across jurisdictions and manipulation of case facts. Theoretical and practical implications for research and for identifying impartial jurors at voir dire are discussed.
