Improved Area of Origin Estimation for Bloodstain Pattern Analysis Using 3D Scanning

An important component of crime scene reconstruction is bloodstain pattern analysis (BPA). Where BPA concerns impact patterns, estimating the area of origin is critical information for scene reconstruction. Traditionally, this is achieved by measuring individual bloodstains and performing trigonometric calculations; however, 3D scanning has been proposed as a viable alternative for overcoming logistical and practical concerns with the manual method. Therefore, this project aimed to establish whether the FARO Focus 3D scanner and FARO Zone 3D software can improve the accuracy of area of origin estimates relative to the manual method. We created a series of eight bloodstain impact patterns and performed paired analysis using the two methods to estimate areas of origin for each pattern. Our data suggested that FARO-derived estimates were generally more accurate than using the manual method. FARO-estimated heights of origin areas were generally closer to the true distance. Both methods underestimated the distance from the wall for most patterns originating 150mm or greater from the wall, but overestimated distances for patterns originating closer to the wall. The degree to which distances were underestimated increased significantly the further the blood source was from the wall and was greater for FARO-derived estimates. The results of this research contribute to the validation of these instruments for operational implementation for BPA and should be considered alongside the practical benefits of 3D scanning relative to manual methods. Further, 3D scanning can provide reliable BPA reconstruction documentation for technical review and court presentation.     

Testifying in an International War Crimes Tribunal: The Experience of Witnesses in the Special Court for Sierra Leone

The research described in this article investigates the extentto which witnesses who testified in the Special Court for SierraLeone (SCSL) report the experience as positive or negative.It also seeks to identify the factors that contribute to theseevaluations. It reports the results of structured interviewsconducted with 171 witnesses who testified in the SCSL. Thefinding that emerges most strongly is that the experience oftestifying was positive for the majority of witnesses. The courtroomenvironment was experienced as supportive, and witnesses ratedthe experiences of both examination-in-chief and cross-examinationas being more positive than negative, with examination-in-chiefbeing the more positive of the two. The findings suggest thata positive testimony experience can be predicted when a witnessdoes not feel worried at the prospect of testifying, feels respectedby court staff and, to a lesser extent, has a positive experienceof cross-examination.     

The Ends of Deliberation: Meta‐consensus and Inter‐subjective Rationality as Ideal Outcomes

Normative deliberative theory has contributed much to an understanding of ideal procedural standards, but there is considerable uncertainty regarding the appropriate nature of desired deliberative outcomes. In this paper we identify two inter‐related concepts of meta‐consensus and inter‐subjective rationality as outcomes that an authentic deliberative process ought to produce. Importantly, these deliberative ends are consistent with ideal deliberative procedure. They are also empirically tractable, where preference transformation can be described in terms of underlying values, and judgments. Methods for assessing deliberative ends are provided and demonstrated using a case study.     

Developments in the Law: Garcetti v. Ceballos and the Workplace Freedom of Speech Rights of Public Employees

On May 30, 2006 the Supreme Court handed down a 5–4 decision in the case of Garcetti v. Ceballos, announcing that "when public employees make statements pursuant to their official duties, they are not speaking as citizens for First Amendment purposes, and the Constitution does not insulate their communications from employer discipline." Previously, the Court had held in Pickering v. Board of Education (1968) that the First Amendment's protection of freedom of speech generally prohibited public employers from firing or disciplining employees for speaking out on matters of "public concern." The Pickering decision established a two-part test that first required federal courts to determine whether the employee had spoken out on a matter of public concern and then whether the disruptive impact of the employee's statement justified the disciplinary action. This article argues that the Garcetti decision may deter many public employees from disclosing governmental inefficiency and misconduct and presenting dissenting viewpoints on matters of clear public concern. Consequently, the decision may make it more difficult for the leadership of public agencies to uncover inefficiency and misconduct.     

Worrying about misconduct: the control lobby and the PS 2000 reforms

Abstract: In 1989, the Canadian government announced a plan to reform the federal public service that would reduce the number of rules imposed on line managers and promote a “results-oriented, entrepreneurial” culture. Public discussion about the reforms was dominated by a community of groups and individuals, which the author characterizes as a “control lobby.” Constituents of the control lobby worried that the proposed reforms would undermine parliamentary control over the public service and increase bureaucratic misconduct. The lobby slowed implementation of, and caused modifications to, institutional reforms and undercut efforts towards culture change. The attention that it gave to incidents of perceived misconduct may also have reinforced popular beliefs about the dangers of reform. The paper describes the key members of the control lobby, their reaction to the PS 2000 reforms and attempts by reform leaders to respond to their concerns. It suggests that a major weakness of the PS 2000 initiative was its failure to anticipate and craft a response to worries expressed by the control lobby. Sommaire: En 1989, le gouvernement canadien a annoncé un plan de réforme de la Fonction publique fédérale visant à réduire le nombre de règles régissant les gérants hiérarchiques et à promouvoir un «esprit d'entreprise axé sur les résultats». Le débat public concernant ces réformes a été dominé par un ensemble de groupes et d'individus caractérisés par l'auteur comme étant des partisans du contrôle. Ces derniers s'inquiétaient du fait que les réformes proposées risquaient de soustraire la fonction publique au contrôle parlementaire et d'augmenter les vicissitudes bureaucratiques. Ce groupe de pression a ralenti la mise en oeuvre des réformes institutionnelles et les a modifiées, et il a sapé les efforts visant à faire évoluer les esprits. Ayant attiré l'attention sur les incidents où il semblait y avoir un comportement incorrect des fonctionnaires, il a peut-être aussi réussi à renforcer les croyances populaires concernant le danger des réformes. L'article décrit les principaux membres de ce groupe de pression, leur réaction face aux réformes de la FP 2000, et les efforts des leaders de la réforme pour répondre à leurs inquiétudes. II suggère que le fait de ne pas avoir prévu les inquiétudes exprimées par les partisans du contrôle et de ne pas avoir préparé de réponse adéquate constitue une faiblesse importante de l'initiative FP 2000.     

An Early Community-Based Intervention for the Prevention of Substance Abuse and Other Delinquent Behavior

This paper presents the results of an evaluation of an early intervention, risk-reduction strategy versus a standard intervention approach in the treatment of inner-city youth at high risk of adopting a deviant lifestyle. It examines baseline and 1-year follow-up information provided by 408 youth admitted to 2 community-based Baltimore City Youth Bureaus offering counseling services for neighborhood youth referred for delinquent and other problematic behavior. In the study, one of these bureaus served as the experimental intervention clinic and the other as the control, or standard intervention, clinic. Outcome measures involved substance abuse; sexual activity; contact with juvenile authorities; and delinquent activity, including violence-related activity. Regression analyses of outcome measures revealed significant differential results for delinquent activity, which favored the experimental intervention. Relationships between risk/protective factors and outcome are discussed.
