A further study to investigate the detection and enhancement of latent fingerprints using visible absorption and luminescence chemical imaging

This study investigated the application of chemical imaging to the detection of latent fingerprints using the Condor macroscopic chemical imaging system (ChemImage Corp., Pittsburgh, USA). Methods were developed and optimised for the visualisation of untreated latent fingerprints and fingerprints processed with DFO, ninhydrin, cyanoacrylate, and cyanoacrylate plus rhodamine 6G stain. The results obtained with chemical imaging were compared to the detection achieved using conventional imaging techniques. The Condor significantly improved the detection of many prints, especially those that might be considered poor quality or borderline prints. Prints on newspaper treated with ninhydrin and DFO, and prints on white and yellow paper treated with ninhydrin, benefited the most from chemical imaging detection. In many cases, fingerprints undetectable using conventional imaging techniques could be visualised with chemical imaging. Ridge detail from untreated prints on yellow paper was also detected using the Condor. When prints of high quality were examined, both detection techniques produced quality results. The results of this project demonstrate that chemical imaging offers advantages over conventional visualisation techniques when examining latent fingerprints, especially those that would be considered difficult, such as weak prints or prints on surfaces that produce highly luminescent backgrounds. Standard testing procedures for the detection and enhancement of fingerprints by chemical imaging are presented and discussed.     

Lifting the cover on drug courts: evaluation findings and policy concerns

Drug treatment courts emerged in 1989 as a court-based solution to an enormous increase of drug-related arrests. Since their inception, drug treatment courts have been subject to empirical and process evaluations to provide quantitative and qualitative data regarding their effectiveness. This article reviews the extant literature on the effectiveness of drug treatment courts and discusses findings regarding various components of the criminal justice system. It is argued that based on empirical evaluation findings, drug treatment courts have achieved success in lowering rates of recidivism among drug offenders, despite problematic methodological and analytical concerns. This article also presents key components and agents of drug treatment courts and discusses their impact and relevance to policy creation and adaptation. It is suggested that when combined with empirical evaluations, process evaluations provide great insight into the drug-treatment-court dynamic. This article concludes with a discussion of the implications of drug treatment courts for justice policy.     

Blood rights: the body and information privacy

Genetic and other medical technology makes blood, human tissue and other bodily samples an immediate and accessible source of comprehensive personal and health information about individuals. Yet, unlike medical records, bodily samples are not subject to effective privacy protection or other regulation to ensure that individuals have rights to control the collection, use and transfer of such samples. This article examines the existing coverage of privacy legislation, arguments in favour of baseline protection for bodily samples as sources of information and possible approaches to new regulation protecting individual privacy rights in bodily samples.     

TEACHING METHODS IN PUBLIC ADMINISTRATION REVISITED

Methodology courses in MPA programs tend to be unpopular with students and professors alike. These same courses, however, prove to be among the most valuable when the student is completing the degree program or when the student becomes a practitioner of public administration. In this article, many of the most widely used learning models for methodology are critiqued. In addition, the authors make a case for the use of inquiry training techniques, arguing that they are most appropriate for both students and professor because of their environmental sensitivity.     

The sense and the nonsense of school effectiveness

Hanushek misinterprets the data on which he bases his conclusion and draws inappropriate policy implications from them. The goals of a school system affect how its resources are used. Educational goals are highly diverse. Accordingly, the measures of output used in Hanushek's studies are inappropriate. To develop more effective measures, the nature of the teaching and learning process must be much better understood. Fortunately, a solid beginning has already been made among specialists in education on that critical task; but more work is needed.
