On a code of ethics for policy experts

Advances in science and technology have exposed society to risks of unprecedented magnitude, which sometimes must be faced on very short notice, as in the field of nuclear power. Those developments have greatly increased the significance of the opinions of policy experts. When adversaries are pitted against one another on such issues, the risk that policy experts may lose legitimacy in the eyes of the public is very high. At such times, the concern grows that the experts' views may be influenced by pressure from their principals or by conflicts of personal interest. One step that could reduce the risk of a loss of legitimacy for policy experts is to develop a code of ethics, which would include such issues as defining the responsibility of the expert, identifying unacceptable conflicts of interest, determining the expert's obligations regarding secrecy and disclosure, and developing standards for the process of decision-making in emergencies.     

Social protection

The term ‘social protection’ has been widely used around the world and is often treated as synonymous with ‘social security’, which is misleading. This article considers the numerous terms that have become part of the language of social protection, indicating that the image conveyed by the term is rather different from what is meant by it.     

Implantation of an RFID-tag into human molars to reduce hard forensic identification labor. Part 2: physical properties

Modifying and implanting existing RFID-tags into extracted human molars was described previously [P. Thevissen, G. Poelman, B. Puers, M. De Cooman, G. Willems, Implantation of RFID-tag into human molars to reduce hard forensic identification labor. Part 1. Working principle, Forensic Sci. Int. 156 (2006)]. Maximal vertical occlusal load during which the implanted RFID-tags remain active was evaluated in vitro. The temperature dependency of the implanted RFID-tags was studied on the extracted teeth to find out the maximal obtainable temperature before failure and a test with embedded thermistors to verify temperature distributions. The maximal working temperature of the implanted RFID-tags was revealed and gave indications for the set-up of measuring intra oral and intra tooth temperature during the cremation of a human body. Fatigue was induced on the implanted teeth by thermocycling. The results of this investigation showed the need of putting an extra insulating layer around the modified tags before implantation. The different in vitro tests indicated that the implanted RFID-tags can support certain oral and forensic circumstances.     

Racemization of aspartic acid from human dentin in the estimation of chronological age

The estimation of chronological age in cadavers, human remains and in living human beings by various methods is discussed. These methods, which are based on the age dependent non-enzymatic changes of l-form amino acids to d-form amino acids, mainly aspartic acid, are among the most reliable and accurate methods to date. Most of these methods use gas chromatography (GC). In this review, results of aspartic acid racemization in dentin at different targets are discussed. In addition, pre-considerations and guidelines are given for the selection of dentin from teeth. A pilot project was run to evaluate the efficiency of high performance liquid chromatography (HPLC) coupled with fluorescence detection. New buffer conditions were found to obtain stable derivatives of aspartic acid enantiomers for the estimation of racemization.     

The challenge of diversity management: police reform and the Arab minority in Israel

Diverse societies present different challenges for police forces that have to gain the trust and legitimacy of minorities. Police forces must develop the ability to engage with diversity and overcome their own biases and prejudices in order to better serve minorities. Police reforms, however, may fail to address the challenge successfully if core problems are not clearly identified. In such a case, reforms may be misdirected and fail to achieve the desired results. This paper, based on a study of the Arab minority in Israel, suggests a bottom-up approach that concentrates on identifying the attitudes of minority groups as the basis for any reform plan. A survey was conducted among Arab citizens to identify general attitudes, perceptions of over-policing and under-policing and assessment of three potential reforms; recruitment of minority members into the police, community involvement in policing, and cultural training for police officers.
