The spatial distribution of random gunfire: A block-level investigation of physical and social structural conditions

This paper examines the environmental and social structural correlates associated with random gunfire incidents. The study group consists of 273 face blocks and intersections in a selected portion of Dallas, Texas. The data show some locations routinely generate random gunfire, while others remain gunshot-free. The analysis suggests environmental factors are not sufficient to explain random gunfire. Implications for future inquiries are offered. The research for this paper was supported by Grant No. DOJ-OH-6-8971 from the National Institute of Justice. Findings and conclusions of the research reported here are those of the authors and do not necessarily reflect the official position or policies of the U.S. Department of Justice.

Case study of three generations of incarcerated sexual offenders

In an attempt to better understand sexual offenders, this study with the aid of a genogram utilizing a grounded theory approach examined the experiences of three generations of incarcerated sexual offenders. The offenders in this study described experiences characterizing a continuum of failure to control their own criminal offences and perpetuity of their chronic conduct despite its serious consequences including imprisonment. One implication of those findings is that some incarcerated chronic sexual offenders possess a predisposition towards a sexual addiction and accordingly, a biological inheritance and environmental factors contribute to their conduct. Therefore, it is recommended for correctional systems including supervisory care that mandatory treatment within a medical model of confinement as opposed to a punitive model be established in order to curve recidivism and victimization levels. A longitudinal study should be conducted consisting of family members who are violent sexual offenders.     

Crisis of confidence: The case of Britain

Britain is a good test case for claims that dissatisfaction is causing a crisis of confidence. Britain has one of the longest and most stable of democracies. The political system itself is protected by tradition, and people seem satisfied with many non-political institutions and have modest expectations. Support for anti-system parties or revolutionary alternatives is minimal. Since 1996 Dennis Kavanagh has been Professor and Head of the School of Politics and Communication Studies at the University of Liverpool. Prior to this he was at the University of Nottingham and the University of Manchester. His areas of special interest are British politics and British elections.     

The Impact of Juvenile Court Judge Ethical Orientation on Decision Making

This exploratory study examines the ethical ideologies of a sample of 76 juvenile court judges attending a conference using an Ethical Position Questionnaire. Potential effects of ethical orientation on judicial decision making are identified and discussed. The findings indicate a relatively even distribution of judges across ethical ideologies. The connection between ethical ideology and the prevailing juvenile justice philosophy across jurisdictions, and the importance and complexity of judicial education and training in juvenile justice, are discussed.     

Developmental validation of the AmpFℓSTR® Identifiler® Plus PCR Amplification Kit: an established multiplex assay with improved performance

Abstract: Analysis of length polymorphism at short tandem repeat (STR) loci utilizing multiplex polymerase chain reaction (PCR) remains the primary method for genotyping forensic samples. The AmpF?STR^® Identifiler^® Plus PCR Amplification Kit is an improved version of the AmpF?STR^® Identifiler^® PCR Amplification Kit and amplifies the core CODIS loci: D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, CSF1PO, FGA, TH01, TPOX, and vWA. Additional loci amplified in the multiplex reaction are the sex‐determinant, amelogenin, and two internationally accepted loci, D2S1338 and D19S433. While the primer sequences and dye configurations were unchanged, the AmpF?STR^® Identifiler^® Plus PCR Amplification Kit features an enhanced buffer formulation and an optimized PCR cycling protocol that increases sensitivity, provides better tolerance to PCR inhibitors, and improves performance on mixture samples. The AmpF?STR^® Identifiler^® Plus PCR Amplification Kit has been validated according to the FBI/National Standards and Scientific Working Group on DNA Analysis Methods (SWGDAM) guidelines. The validation results support the use of the AmpF?STR^® Identifiler^® Plus PCR Amplification Kit for human identity and parentage testing.     

Dextromethorphan abuse leading to assault, suicide, or homicide

Abstract: Dextromethorphan is a commonly encountered antitussive medication which has found additional therapeutic use in the treatment of pseudobulbar disorder and as an adjunct to opiate use in pain management. Dextromethorphan at high doses has phencyclidine‐like effects on the NMDA receptor system; recreational use of high doses has been found to cause mania and hallucinations. The toxicology and pharmacology of the drug in abuse are reviewed, and the historical literature of adverse psychiatric outcomes is assessed. Five new cases of dextromethorphan intoxication that resulted in assault, suicide, and homicide are reported, together with the corresponding toxicology results. Blood concentrations ranged from 300 to 19,000 μg/L. These results are compared with typical concentrations reported in therapeutic use and impaired driving cases. Based on these findings, dextromethorphan should be considered as a potential causative agent in subjects presenting with mania, psychosis, or hallucinations, and abusers are at risk for violent and self‐destructive acts.
