Monitoring of Levamisole Concentration in Serum of Traffic Participants after Cocaine Consumption

This study highlights the problem of levamisole‐adulterated cocaine in context of active traffic participation. For the purposes of levamisole concentration monitoring in human serum, an analytical method based on LC‐MS/MS and solid‐phase extraction was applied. A Luna 5 μm C18 (2) 100 A, 150 mm × 2 mm column and a mobile phase consisting of A (H₂O/methanol = 95/5, v/v) and B (H₂O/methanol = 3/97, v/v), both with 10 mM ammonium acetate and with 0.1% acetic acid (pH = 3.2), were used. The validation experiments demonstrated that the method applied was appropriate for levamisole quantification in human serum. For 23% of levamisole‐positive samples, the concentrations exceeded 20 ng/mL. Therefore, the interaction of this drug with cocaine has to be considered as important for active traffic participation. As a consequence, monitoring of levamisole concentration in human serum is recommended, as long as it is used as cocaine adulterant.     

The Reliability of Pattern Classification in Bloodstain Pattern Analysis,Part 1: Bloodstain Patterns on Rigid Non‐absorbent Surfaces

This study was designed to produce the first baseline measure of reliability in bloodstain pattern classification. A panel of experienced bloodstain pattern analysts examined over 400 spatter patterns on three rigid non‐absorbent surfaces. The patterns varied in spatter type and extent. A case summary accompanied each pattern that either contained neutral information, information to suggest the correct pattern (i.e., was positively biasing), or information to suggest an incorrect pattern (i.e., was negatively biasing). Across the variables under examination, 13% of classifications were erroneous. Generally speaking, where the pattern was more difficult to recognize (e.g., limited staining extent or a patterned substrate), analysts became more conservative in their judgment, opting to be inconclusive. Incorrect classifications increased as a function of the negatively biasing contextual information. The implications of the findings for practice are discussed.     

Why We Need Postmortem Analysis of Cardiac Implantable Electronic Devices

The prevalence of cardiac implantable electronic devices (CIEDs), pacemakers and implantable cardioverter defibrillators (ICDs) is increasing. However, postmortem analysis of CIEDs is not performed routinely. Fourteen consecutive CIEDs were analyzed. The indication for and date of implantation, technical data, CIED reprogramming, heart rhythm disturbances, patient demographics and medical consultations were investigated. Death during the first year after implantation was seen in 54%, whereof 71% consulted a physician within 10 days before death. The time of death was attributed to a particular day in 29%. There was a relationship between CIEDs and cause/manner of death in 50%. Although limited by a small sample size, this study advocates the routine postmortem CIED analysis for forensic and clinical purposes in selected cases. Patients with CIEDs seem to show an increased risk of death during the first year after implantation. The analysis of CIEDs can be helpful in evaluating the time/cause/manner of death.     

Identities Through Time: An Exploration of Identity Change as a Cause of Desistance

Research examining desistance from crime (the process of decreasing offending over time) has increased over the last 20?years. However, many explanations of desistance remain somewhat exploratory. One theory in particular that is becoming more prominent includes the idea that desistance is caused by a change in identity (e.g. from deviant to pro-social). While qualitative support has been found for this proposition, prospective quantitative studies have not been conducted on this theory. This study addresses that gap by examining how pro-social identities change over time and whether these changes correspond to desistance from crime. The results of growth curve models indicate that pro-social identity increases over time and is a robust predictor of criminal behavior over the life course. These results offer support to identity theories of desistance and also provide important information for correctional programming.     

Better Politicians: If We Pay,Will They Come?

While each election provides the Canadian House of Commons with a fresh batch of politicians, no consideration has been given to the question of whether the quality of politicians is improving. Yet improving quality has been the focus of several commissions urging increases in MP compensation. This article addresses the competence and compensation questions by asking whether changes in levels of compensation might make a difference to the educational qualifications of political leaders. We assemble a unique dataset of 1,291 federal politicians elected to the Canadian House of Commons from 1993 to 2011 and show that prime ministers do have a preference for more highly educated MPs when filling ministerial and other executive positions. Our findings suggest that certain subgroups of MPs, particularly educated women, may be attracted by upward shifts in compensation. We discuss the reasons for these effects and the relative importance of compensation in career decisions.     

Malawi and the transition and adherence to multi-party democracy

In July 1993 the author served as a chairman and rapporteur of the Round Table, which facilitated the transition of Malawi to a multi-party democracy. It helped to end the life presidency of the inaugural president, Dr Hastings Kamuzu Banda. In February 1994 the author served as co-chair of the National Constitutional Conference that cleared the way on remaining differences and led to the first free elections that resulted in the election of President Bakali Maluzi. Despite occasional difficulties, Malawi has adhered to constitutionalism and repeatedly witnessed peaceful transitions of presidential power. The importance of neutral international facilitation of the transition is emphasised and described.     

Kant with Freud: Derrida’s Analysis of the Ancient Dream of Self-Punishment

During his 2000–2001 seminar on the death penalty, Jacques Derrida argues that Kant is the most ‘rigorous’ philosophical proponent of the death penalty and, thus, the thinker who poses the most serious objections to the kind of philosophical abolitionism that Derrida is trying to develop in his seminar. For Kant, the death penalty is the logical result of the fundamental principle of criminal law, namely, talionic law or the right of retaliation as a principle of pure, disinterested reason. In this paper, I demonstrate how Derrida attempts to undermine Kant’s defence of the death penalty by demonstrating both its internal contradictions (the tenuous distinction between poena forensis, that is, punishment by a court, and poena naturalis, natural punishment) and its strange affinities with the law of primitive peoples (as understood by Freud in Totem and Taboo). I argue that Derrida’s repeated returns throughout the seminar to Kant’s Metaphysics of Morals suggest that Kant’s seemingly rational defence of the death penalty is ultimately motivated by interests that belie the supposed disinterestedness of modern law and by a notion of natural justice that at once subtends and subverts all criminal law.     

Effects of the NICHD Protocol Training on Child Investigative Interview Quality in Korean Police Officers

This study was conducted to determine, by comparing pre- and post-training interview of 18 Korean police officers, whether training in use of the NICHD Protocol improved the quality of investigative interviews of allegedly abused child victims. Results showed that Korean police officers more often followed the Protocol structure -they introduced themselves, explained the ground rules, and conducted episodic memory training-after they had been trained. Moreover, police officers used approximately three times as many desirable prompts (such as invitations and facilitators) and fewer suggestive prompts in interviews conducted after as opposed to before the training. Invitations elicited approximately four to seven times more details on average than the least productive prompts. These results confirmed that the NICHD Protocol is effective when used to interview alleged child abuse victims in East Asia.     

Eyewitness Identifications by Older and Younger Adults: A Meta-Analysis and Discussion

The current meta-analysis compared younger and older adult eyewitness identification accuracy and includes analyses designed to determine what witness and event factors might moderate any differences found. Results showed that, regardless of lineup type and perpetrator age, older eyewitnesses are reliably worse at making correct lineup decisions than younger eyewitnesses whether they are identifying perpetrators or rejecting perpetrator-absent lineups. Discussion of possible causes for this difference in identification accuracy is drawn from cognitive and social psychology literatures, and possible implications for future research and public policy are put forth.
