Forensic identification of resampling operators: A semi non-intrusive approach

Recently, several new resampling operators have been proposed and successfully invalidate the existing resampling detectors. However, the reliability of such anti-forensic techniques is unaware and needs to be investigated. In this paper, we focus on the forensic identification of digital image resampling operators including the traditional type and the anti-forensic type which hides the trace of traditional resampling. Various resampling algorithms involving geometric distortion (GD)-based, dual-path-based and postprocessing-based are investigated. The identification is achieved in the manner of semi non-intrusive, supposing the resampling software could be accessed. Given an input pattern of monotone signal, polarity aberration of GD-based resampled signal's first derivative is analyzed theoretically and measured by effective feature metric. Dual-path-based and postprocessing-based resampling can also be identified by feeding proper test patterns. Experimental results on various parameter settings demonstrate the effectiveness of the proposed approach.     

Mechanism of methamphetamine intoxication and its medical identification

Methamphetamine (MA) is a representative drug of amphetamine-type stimulants for central nervous system and has become one of the most dangerous drugs in the world recently. The present article reviews the pharmacological effects, distribution, metabolism, intoxication mechanism, the effects of MA on cardiovascular and central nervous systems of MA, and the current situation of forensic investigation on MA.     

网络恐怖主义中的“伊斯兰国”

从传播的社会政治维度来看,以推特和脸谱为代表的新兴媒体不仅能点燃"阿拉伯之春",而且也能将网络恐怖主义推向新的高度。从某种意义上来说,"伊斯兰国"恐怖组织的兴起正是一次恐怖主义在新媒体背景下的全新生长,代表网络恐怖主义的一种最新趋向。由伊斯兰国恐怖组织所反映的网络恐怖主义最新发展变化,为我国应对网络恐怖主义提供了诸多启示,再一次证明遏制恐怖主义离不开有效的全球治理。     

基层公安机关开展精细化考评的探索与思考——以上海市公安局长宁分局为例

精细化考评是指通过规则的系统化和细节化,运用程序化、标准化、数据化和信息化的手段,使组织管理各单元高效、协同和持续运行并努力实现组织目标最优化的考核理念、考评方法和管理文化。其精髓是崇尚"细节决定成败"信念,强调科学考评、精细操作。当前,公安机关工作任务繁重、基层民警的工作压力普遍较大,在警力数量无法快速增加的情况下,通过推行精细化考评,有效提升队伍工作效能,是实现警力无增长改善的必经之路。

印尼棉兰的客家人——海外客家人的社会变迁之三

提起印尼棉兰的华人,人们马上会说这里福建人很富有,很能干,经商成功。其实,最早来到此地并为这里的开发立下汗马功劳的应该是客家人,印尼棉兰开埠功臣是梅县人张榕轩,在印尼棉兰的发展史上写下了光辉的一页,我们有理由为客家人祖先在棉兰曾经创造的辉煌而感到自豪。此外,以海陆丰客家人为主体的日里各大小烟草种植园工人,曾经为当年日里的经济发展流血、流汗,他们的功绩不可抹杀。     

Development and reform of police training and education in Taiwan

This article describes the development of training and educating police officers in Taiwan. The current system, which has largely survived the democratic transition between 1986 and 2000, is unique. It is a two-track system in which Taiwan Police College (TPC) is responsible for training low ranking police personnel, whereas Central Police University (CPU) is responsible for educating police management personnel. Currently, the presidents of CPU are no longer chosen from the military, but their backgrounds require experiences as police officers. The Examination Yuan opens up the new route into TPC and CPU through competitive national civil examinations. Echoing the outcry for reform within Taiwan and abroad, we advocate to liberate new cadets from the closed system so that they can learn together with other non-police students and to add more social science materials into the police education curriculum.

社区化党建:当代农村基层党组织建设的现代转换

新中国成立后,农村基层党组织建设主要经历了以生产队为载体的党支部"行政化、全能化"、行政村为载体的农村治理"领导者、决策者与支配者"两个阶段。在现代化发展进程中,乡村经济社会发展的内外环境不断变迁,这些都推动着农村基层党建的现代转换。以当代农村新社区为载体实施社区化党建,能够顺应现代农村经济社会发展的现实要求,是新时期基层党组织建设的重要发展方向。当然,当代农村推进社区化党建,还需要结合农村现实基础进行一系列的改革与创新。     

关于公证拓展与规范的应然性思考

构建社会主义和谐社会,为公证事业的发展注入了强劲的背景动力、形势支撑和前瞻性预期;公证所具有的证明、信用、秩序、沟通、服务、预防、监督等内在价值和外显功能,必将释放更加显著的独特作用。公证拓展和规范,应该进一步加强对公证制度、公证队伍、公证公信力、公证环境的培育、培养和培植;抓紧建立健全公证管理体系中的行政控管机制、行业自律机制、公证处规范化建设机制、公证责任机制和公证程序机制;厘清公证执业活动中交织存在的权力关系、权利关系和利益关系,始终坚持维护公证的国家公权性、权威性、程序性、公益性、非竞争性和必要的消极性、被动性。
