This paper discusses the organization of the first international proficiency test (PT) programme on ketamine (K) and norketamine (NK) in hair samples. The primary objective of the programme was to evaluate the analytical capability of participating laboratories on hair analysis for K and NK via comparison of results. Authentic samples, instead of spiked samples were used in the programme to mimic the analysis of incorporated illicit drugs in real-life situations. Eight of the ten participating medical or forensic laboratories from Australia, France, Hong Kong, Italy, Singapore and the USA returned results to the organizer. Quantification methods from these laboratories were confined to GC-MS and LC-MS/MS. Performance assessment based on z-score indicated that only three laboratories achieved satisfactory results for both the analysis of K and NK. It was concluded that the overall performance of the participating laboratories was fair and there is still room for further improvement. Additional similarly designed PT programmes are recommended to be organized in order to encourage reliable measurements of illicit drugs in hair samples. Taking into account the substantial effect on the consensus values within limited number of data points, a recommendation on the provision of reference values assigned by accurate methods will be of benefit to small size PT programmes in the forensic field. 相似文献

The utilization of 3D computerized systems has allowed more effective procedures for forensic facial reconstruction. Three 3D computerized facial reconstructions were produced using skull models from live adult Korean subjects to assess facial morphology prediction accuracy. The 3D skeletal and facial data were recorded from the subjects in an upright position using a cone-beam CT scanner. Shell-to-shell deviation maps were created using 3D surface comparison software, and the deviation errors between the reconstructed and target faces were measured. Results showed that 54%, 65%, and 77% of the three facial reconstruction surfaces had <2.5 mm of error when compared to the relevant target face. The average error for each reconstruction was -0.46 mm (SD = 2.81) for A, -0.31 mm (SD = 2.40) for B, and -0.49 mm (SD = 2.16) for C. The facial features of the reconstructions demonstrated good levels of accuracy compared to the target faces. 相似文献

人力资源管理思想:三个里程碑及其在中国的升华 总被引:2,自引:0,他引:2
人力资源管理实践历程中三个标志性实验成果昭示了人力资源管理思想演变的客观规律,是人力资源管理思想嬗变过程中的三大里程碑。科学管理实验使人力资源管理从自发管理走向自觉管理、科学管理和制度管理;霍桑实验系统发现了提高生产效率的社会心理因素,使人力资源管理从技术管理走向社会管理、行为管理和心理管理;职业生涯实验显示员工职业发展也是现代企业管理目标,现代企业目标和员工职业发展目标共存共长。三次实验的思想脉络、理论构造、功能机制有机对接、联动传承并推向纵深,成为人力资源管理历史上三个具有划时代意义的丰碑。科学人才观提出的"以人为本"的思想和理念是人力资源管理思想在当代中国的发展和升华。 相似文献

Through interviews with police and document analysis this article examines the movement of video surveillance images from source to police to the courts in order to assess and refine the surveillant assemblage concept. Using this concept, the case study reveals asymmetrical criminalization processes involving movement of this visual information. The study finds that most video surveillance images transferred to police come from private sources as a consequence of function creep and that their movement epitomizes creation of criminalized ‘data-doubles’. However, the article argues that this criminalizing movement through the police is revealed as less than a seamless process; it is dependent on human labour and encounters forms of resistance along the way that include increased police workload and technological limitations. 相似文献

This paper describes the study of the reaction between 1, 8-diazafluoren-9-one (DFO) with the amino acid L-alanine in methyl alcohol. Particular interest was paid to the possible role of the solvent which appears to react with the DFO to form a hemiketal that is the reactive species. A potential reaction pathway is proposed based on the current data collected. The reaction intermediates and products were identified by a variety of spectroscopic methods including mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, and X-ray crystallography. 相似文献

The Judgment of the International Criminal Tribunal for Rwandain the Media case focuses on the responsibility of three individualscharged on the basis of their control of a radio channel anda newspaper in Rwanda. Due to overt freedom of speech issuesrelating to this Judgment, it was immediately mass-mediatized.This article analyses the case from a purely legal perspective,focusing on the issue of how the Judges determinedthe culpability of individuals for crimes concerning the media'sinfluence in the preparation and execution of mass crimes. Somecritical elements appear in this perspective, including: the(il)legitimacy of the extension of jurisdiction ratione temporis;the (in)opportunity to establish the mens rea of an inchoateoffence via the actus reus of a non-inchoate offence; the (un)certaindistinction between forms of direct and indirect participation;and the (in)determination of the criteria applied to reducethe sentence against one of the accused (as a form of reparationfor the violation of procedure by the Prosecutor). 相似文献

This paper finds that U.S. firms tend to utilize their manufacturing processes when operating in the U.K. but that they adopt the production standards of the host country. Three process technology variables are examined: MRP I (materials requirements planning), JIT (just in time), and TQM (total quality management). While significant differences are found between indigenous plants in each of the two countries, the adoption of these manufacturing technologies is similar for American firms operating in either country. In contrast, U.S. transplants are found to be enthusiastic adopters of ISO 9000, suggesting that host country effects are large when it comes to conforming to regional standards. 相似文献
