Single-item predictive validity of the Short-Term Assessment of Risk and Treatability (START) for violent behaviour in outpatient forensic psychiatry

The single-item predictive validity of the Short-Term Assessment of Risk and Treatability (START) has not been thoroughly investigated, although this has great clinical relevance for the selection of treatment targets. Furthermore, it remains unclear whether the characteristic START additions of scoring strengths next to vulnerabilities and selecting key items, add incremental predictive validity. Finally, predictive validity has primarily been studied in inpatient settings and included mainly patients with a psychotic disorder. We analysed data from a mixed diagnostic sample of 195 forensic psychiatric outpatients with a 3-month and 170 patients with a 6-month follow-up period, using logistic regression analysis. The occurrence of violent or criminal behaviour was established based on the case manager’s recordings in the patient’s file. Only 5 of the 20 START items were found to have predictive validity: Impulse Control, Attitudes, Material Resources, Rule Adherence and Conduct. The last three were the only items for which incremental predictive validity was found with respect to scoring it as a strength and a vulnerability. Selection of key items did not add to the predictive validity. While possibly having therapeutic significance, the scoring of strength next to vulnerability and the selection of key items, may not be beneficial for risk assessment.     

Establishing Trust in the Illegal Wildlife Trade in China

This study focusses on the role of trust in the illegal distribution of protected wildlife in China. This research attempts to contribute to the literature by disentangling the establishment of trust within the illegal wildlife trade based on ethnographic fieldwork between 2011 and 2016. Both traders and consumers are resorting to mechanisms of trust to foster exchange and to increase credibility of their agreements. This study discusses the existence of such mechanisms of trust within wildlife trafficking networks that are rather characteristic of illegal wildlife trade in China.

     

What is Fair Punishment for Alex or Ahmed? Perspective Taking Increases Racial Bias in Retributive Justice Judgments

Previous research frequently found that perspective taking may reduce various sorts of racial biases. In the present research, we propose that perspective taking may increase racial bias in the specific context of retributive justice judgments, that is, evaluations of what punishment is considered fair for offenders. In two studies, we manipulated whether or not participants took the perspective of a target offender, who was named either Alex or Ahmed. Results revealed evidence for racial bias under conditions of perspective taking in both studies: Perspective taking increased punishment for Ahmed, but not for Alex, in a theft case (Study 1). Furthermore, perspective taking decreased punishment for Alex, but not for Ahmed, in the case of less severe offense that is less clearly intentional (Study 2). The consequence is similar in both studies: More severe retributive justice judgments for Ahmed than for Alex under conditions of perspective taking.     

Foreign policy options for a new South Africa

Progress towards the creation of a post‐apartheid South Africa raises questions about future foreign policy. In this article a framework for analysis and forecasting is developed. The basic assumption is that a future foreign policy will be driven by the kind of regime which will emerge in a New South Africa. Such a regime will have to develop foreign policy orientations to deal with its regional and global environments and the manifestation of a variety of foreign policy issues in these environments.

A semi‐democracy is foreseen for a New South Africa which will adopt a regional leadership oreitnation towards its neighbours and a consumer orientation towards the global community. The framework makes provision for regime improvements which will lead to fuller international participation or regime decline which will result in international marginalisation.     

Human rights and development: the case of local government transformation in South Africa

Local governments throughout the world are assuming a more important role in economic development of their communities as an increasing number of governments begin to decentralise powers and functions. As these lower levels of government seek sustainable local economic development (LED) strategies the human rights approach towards development becomes pertinent as globalisation accelerates. This article proposes an emphasis on socio‐economic rights as the basis for sustainable LED in developing countries. The article is based on the experience of South African local government in the period after 1994, leading up to the first democratic local government elections on 5 December 2000. Proceeding from the view that the promotion of human rights is necessary for the promotion of economic development, the article critically assesses the role of local government in the promotion of LED through a rights‐based approach. It is argued that the identification in the South African Constitution of local government with basic service provision (recently emphasised by a Constitutional court judgement) will place socio‐economic rights at the centre of LED strategies in South Africa. It is argued that this is indeed the most appropriate cornerstone of LED in South Africa. However, the transformation process that leads the country towards its progressive Constitution needs to be maintained and this article identifies five broad areas for transformation that may still be needed to entrench an adequate human rights culture within the sphere of local governance.

A survey of reported synthesis of methaqualone and some positional and structural isomers.

Methaqualone (2-methyl-3-o-tolyl-4(3H)-quinazolinone) is the illicit synthetic drug of choice amongst South African drug users. Historically police and forensic investigation has proven that all methaqualone seized by the South African Police Service originates from illicit manufacturing sites both inside, and outside South Africa's borders. From a drug enforcement, and forensic point of view it is, thus, of utmost importance that the various synthetic routes available to the illicit "chemist" are fully documented and understood. This is a prerequisite for effective illicit laboratory investigation, as well as chemical and precursor monitoring. This paper gives a brief introduction to the current status with regard to methaqualone use and production in South Africa, as well as an extensive review of the synthesis of methaqualone and selected isomers reported since 1946. A table summarizing synthetic routes reported in 32 reference sources is provided.     

Beware of the possibility of fingerprinting techniques transferring DNA

Fingerprinting brushes have the potential to collect and transfer DNA during powdering. Squirrel-hair fingerprint brushes exposed to specific sets of saliva stains and brushes used in routine casework were tested for their ability to collect and transfer DNA containing material using standard DNA extraction procedures and AmpFlSTR Profiler Plus amplification and typing procedures. The tests found that the risk of transferring DNA during powdering and having a detrimental impact on the analysis increases if the examiner powders over either biological stains (such as blood or saliva) or very fresh prints and uses more sensitive PCR amplification and typing procedures. We advocate caution when powdering prints from which DNA may also be collected and provide options for consideration to limit the risk of transferred DNA contamination while fingerprinting.     

Juvenile sex offenders: a group on its own?

There is some debate about whether sex offenders are similar to non-sex offenders. It is known that sex and non-sex offenders are heterogeneous groups. Comparative studies must take this heterogeneity into account. Based on an aggregated database, a study was conducted among adjudicated juvenile (sex) offenders. The sample consisted of juvenile male sex and non-sex offenders who had been subjected to a psychological assessment at the request of the judge or district attorney. The central question focused on the differences between juvenile sex offenders, in particular rapists and sexual assaulters (n = 57), child molesters (n = 55), and non-sex offenders: violent (n = 85) and nonviolent offenders (n = 80). The results demonstrated that sex offenders differ from non-sex offenders with regard to demographic characteristics, problem behavior, and personality traits. Some reference is made regarding future research.     

Highly sensitive screening method for nitroaromatic, nitramine and nitrate ester explosives by high performance liquid chromatography-atmospheric pressure ionization-mass spectrometry (HPLC-API-MS) in forensic applications

A highly sensitive screening method based on high performance liquid chromatography atmospheric pressure ionization mass spectrometry (HPLC-API-MS) has been developed for the analysis of 21 nitroaromatic, nitramine and nitrate ester explosives, which include the explosives most commonly encountered in forensic science. Two atmospheric pressure ionization (API) methods, atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI), and various experimental conditions have been applied to allow for the detection of all 21 explosive compounds. The limit of detection (LOD) in the full-scan mode has been found to be 0.012-1.2 ng on column for the screening of most explosives investigated. For nitrobenzene, an LOD of 10 ng was found with the APCI method in the negative mode. Although the detection of nitrobenzene, 2-, 3-, and 4-nitrotoluene is hindered by the difficult ionization of these compounds, we have found that by forming an adduct with glycine, LOD values in the range of 3-16 ng on column can be achieved. Compared with previous screening methods with thermospray ionization, the API method has distinct advantages, including simplicity and stability of the method applied, an extended screening range and a low detection limit for the explosives studied.     

Exploratory study on classification and individualisation of earprints

The FearID research project is aimed at the individualisation of earprints for the purpose of forensic research. The study presented here was carried out within the framework of this project. It intends to combine a review of what is known from literature on the classification and individualisation of earprints with results from a preliminary study of earprints. Possibilities for, and limitations to, the use of earprints in forensic investigation are addressed. Differences between eliminating a suspect, placing a suspect at a crime scene, and linking crimes by prints left at different scenes are considered.
