Drug intelligence based on MDMA tablets data: 2. Physical characteristics profiling

One of the tasks of the European project entitled “Collaborative Harmonisation of Methods for Profiling of Amphetamine Type Stimulants” (CHAMP) funded by the sixth framework programme of the European Commission was to develop a harmonised methodology for MDMA profiling and the creation of a common database in a drug intelligence perspective. Part I was dedicated to the analysis of organic impurities formed during synthesis in order to investigate traffic tendencies and highlight potential links between samples, whereas this part focuses on physical characteristics of the MDMA tablets. Diameter, thickness, weight and score were demonstrated to be reliable and relevant features in this drug intelligence perspective. Distributions of samples coming from the same post-tabletting batch (post-TB) and samples coming from different post-TB were very well discriminated by using the squared Euclidean or the Manhattan distance on standardised data. Our findings demonstrated the possibility to discriminate between MDMA samples issued from different post-TB and to find out links between samples coming from a same post-TB. Furthermore, the hypothesis that most of the MDMA samples found on the international market come from the same countries was supported.     

2015年度中国公共政策研究现状与未来展望--基于对“四刊”公共政策类论文的分析

通过对2015年度“四刊”中公共政策类论文进行定量统计和定性分析,可以看到当前的公共政策研究以政策执行、政策网络、公民参与等为热点主题,以定性思辨分析、文献资料研究为主导方法,分布在理论与方法探讨、政策过程研究、工具与价值思考、创新与变迁研究、比较研究与借鉴等多个领域。结合目前的研究现状和实践背景,未来我国的公共政策研究应当向法治化、民主化、科学化、信息化、国际化的方向迈进,以创新理论研究成果,服务当前现实需要。
