国外情报导向警务实践的评价及借鉴性分析

国外情报导向警务的实践是从20世纪90年代开始的,其中英国的国家情报模式和美国的以犯罪情报的计算机统计分析为基础的警务模式起步早,发展较为完善,也最具特色。国外情报导向警务的实践让我们认识到,构建高效运行的情报信息网络平台是实施情报导向警务的技术保障,设立专门的警务情报部门是实施情报导向警务的机构保障,推行规范化的情报工作机制是实施情报导向警务的制度保障,建立专业化的情报队伍是实施情报导向警务的人力资源保障。     

Comment on Parkinson and Cashmore's (2015) Research and Proposal for Reforming Child Custody Relocation Law: Child Custody Evaluator and Psychological Perspecitve

Parkinson and Cashmore ( 2015 ) described their innovative, qualitative, and longitudinal research program on the experience of Australian families involved in relocation family law litigation. This constructive comment discusses the value and limitations of their main findings. Parkinson and Cashmore's approach is contrasted with the excellent quantitative research on the effects of residential mobility on children of divorce. The author disagrees with Parkinson and Cashmore's position of opposing the use of relocation factors in statute and/or case law so as to not hinder the exercise of judicial discretion any further, but agrees with their integration of the least detrimental alternative concept into a relocation analysis.     

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。     

Cell site analysis: Changes to networks with time

Cell service areas may change over time as sites or cells are adjusted, decommissioned or introduced, and there may have been changes between the time of calls and the analysis undertaken. The manner in which survey data is used as part of an analysis is of particular relevance as the data gathered may not reflect the state of the network at the time of calls and thus potentially mislead. Overlaying “historic” data (potentially generated before the calls) with “targeted” surveys (usually generated after the calls) may enable an assessment of possible network changes, or whether additional cells may also have served at a given location at a previous time. This paper outlines a case in which there was a significant time gap between the analysis of call data records and the date on which they were generated.     

Development of a harmonised method for the profiling of amphetamines VI: Evaluation of methods for comparison of amphetamine

Amphetamine samples were analysed by gas chromatography-mass spectrometry (GC-MS), and the peak areas of 33 target compounds were transformed by applying various pretreatment techniques. The objective was to optimise the ability of a number of distance metrics to establish links between samples of amphetamine originating from the same batch (henceforth referred to as linked distances). Furthermore, partial least squares discriminant analysis (PLS-DA) was used to evaluate the effects of various pretreatment methods on separation of amphetamine batches synthesised by the Leuckart reaction, reductive amination of benzyl methyl ketone, and the nitrostyrene route. The most efficient way to pretreat GC-MS data varied for the different distance metrics, although best results were obtained when data were normalised to the sum of peak areas, and either the fourth root or a logarithm was applied to the normalised data. When pretreating normalised data by fourth root transformation, Pearson correlation was the distance metric that was most successful at finding linked samples. Normalisation and the use of fourth root also represented the best method of pretreating data when employing PLS-DA to separate samples synthesised by different routes. To achieve a faster and more user-friendly procedure for evaluating chromatograms, experiments were performed in which the number of target compounds used to compare samples was reduced. The effect of each compound that was removed was studied by applying PLS-DA and by using Pearson correlation to calculate linked distances as well as unlinked distances (between samples from different batches of amphetamine). Considering both links between samples from the same batch and separation of samples synthesised by different routes, the best results were obtained with the data set comprising 26 compounds. Finally, it was found that the profiling method developed in this work was superior to an existing technique with respect to separating linked and unlinked distances.
