Mathematical matching of a dentition to bitemarks: use and evaluation of affine methods

Skin is a less than ideal medium for recording bitemark impressions, and assessing the causes and magnitude of distortion has long been a question in forensic odontology. Affine methods have been suggested as a mathematical means to attempt to quantify the deformation typically seen with a bitemark. Thirty-six bites were created on unembalmed human cadavers with a single dentition. Three mathematical affine methods were evaluated to determine if the distortion could be described mathematically and effectively removed. A measure of mismatch of a dentition to a bitemark was developed based on landmark measurements establishing a numerical basis for comparisons of dentitions to bitemarks. Results indicate high levels of distortion in the bitemarks not attributable to affine deformations or measurement error, suggesting that non-uniform anisotropic properties of skin mostly contribute to the distortion seen, thus concluding that bitemark distortion cannot be corrected by using affine transformations.     

Influencing expert judgment: Attributions of crime causality

Purpose. The present research aimed to investigate the effects of attribution on expert clinical judgment in comparison to semi‐experts and laypeople. Two research questions were addressed. First, would experts be less subject to attributional manipulations, in terms of their perceived ratings of dangerousness, than would semi‐experts or laypeople? Second, would experts be less subject to attributional manipulations, in terms of their assessments of offender responsibility, than would semi‐experts or laypeople? Method. A 3×3×2 mixed groups design was implemented. Participants read nine crime scenarios that had been internally or externally manipulated. For each scenario, participants were asked to rate offender dangerousness, offender responsibility, and the seriousness of the crime and to suggest a suitable sentence length. Targeted recruitment was employed, yielding 12 experts, 21 semi‐experts, and 22 laypeople. Results. Offenders were considered to be more responsible for their actions and more dangerous to others in the internal manipulations than in the external ones across all crime types and by all levels of expertise. Findings indicate that semi‐experts are less subject to the influence of attributional manipulations than both experts and laypeople. Marked similarities in the pattern of expert and lay person judgments can be observed from the present analyses. Conclusions. The current findings lend support to previous research in the area in that similarities between expert and lay person judgment were observed. However, through expanding and clarifying the levels of expertise investigated, the current findings highlight the need for greater research into the distinct ‘semi‐expert’ group.     

Guidelines for the identification of unknown samples for laboratories performing forensic analyses for chemical terrorism

Since the early 1990s, the FBI Laboratory has sponsored Scientific Working Groups to improve discipline practices and build consensus among the forensic community. The Scientific Working Group on the Forensic Analysis of Chemical, Biological, Radiological and Nuclear Terrorism developed guidance, contained in this document, on issues forensic laboratories encounter when accepting and analyzing unknown samples associated with chemical terrorism, including laboratory capabilities and analytical testing plans. In the context of forensic analysis of chemical terrorism, this guidance defines an unknown sample and addresses what constitutes definitive and tentative identification. Laboratory safety, reporting issues, and postreporting considerations are also discussed. Utilization of these guidelines, as part of planning for forensic analysis related to a chemical terrorism incident, may help avoid unfortunate consequences not only to the public but also to the laboratory personnel.     

Psychiatric correlates of medical care costs among veterans receiving mental health care

Research on increased medical care costs associated with posttraumatic sequelae has focused on posttraumatic stress disorder (PTSD). However, the provisional diagnosis of Disorders of Extreme Stress Not Otherwise Specified (DESNOS) encompasses broader trauma-related difficulties and may be uniquely related to medical costs. We investigated whether DESNOS severity was associated with greater nonmental health medical care costs in veterans receiving mental health care. Participants were 106 men and 105 women receiving VA outpatient mental health treatment. A standardized interview assessed DESNOS severity. The dependent variables consisted of primary and specialty medical treatment costs. Sequential zero-inflated negative binomial regression was used to evaluate the variance in medical costs accounted for by DESNOS severity, controlling for PTSD severity and established predisposing, enabling, and need-based health care factors. Contrary to our hypothesis, in fully adjusted models, DESNOS severity independently added a significant amount of variance to lower specialty medical care costs, whereas PTSD did not consistently account for significant variance in medical care costs. Greater DESNOS severity appears to be associated with lower specialty medical care costs but not primary care costs. These findings may indicate that patients with DESNOS symptoms are at risk for being underreferred for specialty care.     

“Not Gods But Animals”: Human Dignity and Vulnerable Subjecthood

Drawing on earlier work on the conceptual structure of dignity, this paper will suggest a particular type of connectedness between vulnerability and human dignity; namely, that the “organizing idea” of human dignity is the idea of a particular sort of ethical response to universal human vulnerability. It is common ground among many, if not all, approaches to ethics that vulnerability requires us to respond ethically. Here, I argue that human dignity is distinctive among ethical values in that it values us because of, rather than in spite of, or regardless of, our universal vulnerability. The term “dignity” is used synonymously with “human dignity” here, since an investigation of the dignity of non-human entities forms no part of the present examination.     

Creating an art therapy anger management protocol for male inmates through a collaborative relationship

A training partnership was established with the Florida Department of Corrections in 2003, and over the ensuing years, art therapy graduate student interns from Florida State University's Graduate Art Therapy Program have been placed in local prisons at different times. Recently, the art therapy interns worked closely with the supervising psychologist in one prison to alleviate and redirect aggression by integrating cognitive-behavioral techniques with art therapy directives. The art therapy interns and the psychologist developed a curriculum using a combination of workbook exercises and art tasks to develop and increase the participants' anger management skills, the Art Therapy Anger Management Protocol. This article provides an overview of art therapy in prison, the cognitive-behavioral approach to anger management with prison inmates, and how art therapy was used to support this approach. Examples of completed art tasks designed to correspond with the workbook curriculum are presented. Overall, this article presents the successful collaboration between the psychologist and art therapists and demonstrates how they facilitated improvement in the participants' anger management skills through this program.     

Police Impersonation: Pretenses and Predators

Empirical research on police impersonation is rare. This research employs quantitative and qualitative methodologies on 2002?C2010 police case files describing impersonation incidents from three police agencies to provide an understanding of the individual and situational constructs associated with police impersonation. Research objectives included: exploring incident characteristics, comparing incidents to national violent crime statistics; and identifying common themes. Results show that police impersonation incidents, offenders, and victims are unique, particularly when compared to national data. Qualitative analysis identified three major themes related to tactics, motivations, and typology. The research offers a framework for establishing policy recommendations.     

Assessing and meeting the health needs of Roman Catholic priests in the archdiocese of Chicago

In 1985, the Bishops' Committee on Priestly Life and Ministry recommended bishops form holistic health boards for their priests based on the results of a 1982 U.S. survey of Catholic priests. In 1995, a holistic health committee was formed under the office of the vicar for priests for the archdiocese of Chicago. One of the committee's first actions was to survey the priests of the archdiocese of Chicago to identify baseline health behaviors and needs. Survey results (n = 524; 52% response rate) revealed the need for the committee to promote health education, preventive care, and annual physicals. The committee conducted a series of health fairs, improved the insurance benefit for an annual physical, and conducted a series of health-related talks targeted to priests. A follow-up survey in 2006 (n = 389; 46% response rate) indicated improvements in health behaviors of the priests. Comparisons to statewide and national data indicate that overall, engagement in healthy behaviors is higher for priests than for men who are not priests.
