Prostitution control in America: Rethinking public policy

In the past two decades there has been little critical examination of the prevailing methods of controlling prostitution in the United States. This article examines selected problems in the control of prostitution in the United States and critically assesses three major alternatives to the prevailing policy of criminalization. Alternative approaches are evaluated using the criteria of public preferences, efficient use of criminal justice resources, and harm reduction. One policy, involving a dualistic approach, is found to be superior in satisfying these criteria. This revised version was published online in July 2006 with corrections to the Cover Date.     

The two conceptual dififculties of specialized evidence

I am distinctively honored to be asked to deliver this address. My admiration for many of the people in this room is overlfowing. Among the Chinese are those who are, literally, responsible for facilitating the long march of China to the rule of law.1 This is no easy task, given the insanity of the Anti-Rightist Movement and the Cultural Revolution that together destroyed any semblance of a rational legal system and as a by-product extirpated, again literally, legal knowledge from China; law schools were closed and books were burned. Over the last few years, I have also come to deeply admire the efforts of the Swiss forensic scientists to establish their various ifelds on sound conceptual and empirical foundations and who are struggling with the very topic of this address, the conceptual difficulties specialized evidence poses for the legal resolution of disputes. The European Network of Forensic Science Institutes' Guideline for Evaluative Reporting in Forensic Science is both a clear statement of these difficulties and offers very helpful recommendations that if implemented would ameliorate some of them.     

Global warming and state-corporate crime: the politicalization of global warming under the Bush administration

Global warming is one of the most significant and difficult issues facing the world today. As result, researchers in a number of disciplines have directed their attention to addressing issues relevant to the study of and responses to global warming. This has been less true in the social sciences, and especially within specific social sciences such as criminology, in comparison to the physical sciences. Global warming does, however, have criminological and sociological relevance on several levels. This article examines one of those levels by exploring the politicalization of global warming under the Bush Administration, and addresses this issue as an example of state-corporate crime.     

Forensic Analysis of Explosives Using Isotope Ratio Mass Spectrometry (IRMS)—Part 2: Forensic Inter-Laboratory Trial: Bulk Carbon and Nitrogen Stable Isotopes in a Range of Chemical Compounds (Australia and New Zealand)

Abstract:  Comparability of data over time and between laboratories is a key issue for consideration in the development of global databases, and more broadly for quality assurance in general. One mechanism that can be utilized for evaluating traceability is an inter-laboratory trial. This paper addresses an inter-laboratory trial conducted across a number of Australian and New Zealand isotope ratio mass spectrometry (IRMS) laboratories. The main objective of this trial was to determine whether IRMS laboratories in these countries would record comparable values for the distributed samples. Four carbon containing and four nitrogen containing compounds were distributed to seven laboratories in Australia and one in New Zealand. The laboratories were requested to analyze the samples using their standard procedures. The data from each laboratory was evaluated collectively using International Standard ISO 13528 ( Statistical methods for use in proficiency testing by inter-laboratory comparisons ). "Warning signals" were raised against one participant in this trial. "Action signals" requiring corrective action were raised against four participants. These participants reviewed the data and possible sources for the discrepancies. This inter-laboratory trial was successful in providing an initial snapshot of the potential for traceability between the participating laboratories. The statistical methods described in this article could be used as a model for others needing to evaluate stable isotope results derived from multiple laboratories, e.g., inter-laboratory trials/proficiency testing. Ongoing trials will be conducted to improve traceability across the Australian and New Zealand IRMS community.     

Photo‐ and Thermal‐Degradation Studies of Select Eccrine Fingerprint Constituents

Abstract: Photo‐ and thermal‐degradation studies on eccrine fingerprint components are presented herein. Dilute distinct solutions of urea, lactic acid, and seven amino acids were deposited on steel coupons and Teflon^® disks, exposed to artificial sunlight or heat, extracted, and analyzed. This aim of this study was to determine whether the investigated eccrine components, previously determined to be Raman active for a parallel study, experienced photo‐ or thermally induced degradation, and if so, to determine the rate and identify any detectable products. Neither the amino acids nor urea exhibited photo‐degradation; however, when heated for a period of three minutes, the onset of thermal‐degradation was initiated at 100°C for the amino acids and 100°C for urea. Lactic acid, the major polymerization initiator of superglue fuming, showed photochemical and thermal‐degradation. These results could be used for future development of new latent fingerprint visualization methods, especially when lactic acid is degraded.     

Revisiting the Thermal Development of Latent Fingerprints on Porous Surfaces: New Aspects and Refinements*

Abstract: Although the ability to develop latent fingerprints on paper using heat alone has been noted previously, it has been considered impractical for casework and inferior to other techniques. Here a new refinement of the technique is demonstrated for the high quality development of latent fingerprints on porous surfaces such as paper. Fingerprints deposited on various papers were developed by exposing them to hot air with a temperature in the vicinity of 300°C, for periods of c. 10–20 sec. Several different heating methods were tested. The novel observation was made that after shorter heating times, fluorescent prints could be observed. These became visible after longer heating times, as noted by earlier workers, but with greatly improved contrast compared with their results. Prints from various donors (and aged prints) were developed with excellent ridge contrast. Direct heating methods (such as with a hot plate or press) produced inferior results. The refined technique, which is simple, safe and inexpensive compared with conventional methods, has great potential for use in forensic laboratories.     

Outsmarting the Liars: The Benefit of Asking Unanticipated Questions

We hypothesised that the responses of pairs of liars would correspond less with each other than would responses of pairs of truth tellers, but only when the responses are given to unanticipated questions. Liars and truth tellers were interviewed individually about having had lunch together in a restaurant. The interviewer asked typical opening questions which we expected the liars to anticipate, followed by questions about spatial and/or temporal information which we expected suspects not to anticipate, and also a request to draw the layout of the restaurant. The results supported the hypothesis, and based on correspondence in responses to the unanticipated questions, up to 80% of liars and truth tellers could be correctly classified, particularly when assessing drawings.
