Research on the local regional similarity of automatic fingerprint identification system fingerprints based on close non-matches in a ten million people database—Taking the central region of whorl as an example

The local regional similarity of fingerprints has always been a hot issue in the field of fingerprint research. With the increasing size of ten-print databases, the appearance of close non-matches (CNMs) in automatic fingerprint identification system (AFIS) candidate lists has attracted increasing attention from forensic science departments worldwide. In this study, three categories (high-, medium-, and low-level) of standards for CNMs were established and 60 whorl samples were marked with different numbers of minutiae to explore the occurrence and influencing factors of CNMs in AFIS candidate lists based on a ten million people database. The results showed that all prints could be found with their corresponding CNMs. The average occurrence rate of CNMs for every query was 52.7% in the top 100 lists, and the most similar CNM was exactly the same in the local area of 12 coincidence points. CNMs appeared more in the middle and lower parts of the central region of the whorl. Moreover, shorter C2C distances and the same finger number and hand led to more CNMs being inspected. CNMs with higher similarity required a more extensive regional area and smaller minutiae density. We concluded that CNMs have a high occurrence rate in large-scale databases and many factors are closely related to them. Fingerprint examiners and researchers need to strengthen their understanding of CNMs to avoid the occurrence of misidentification like the Madrid bombings.     

俄罗斯亚太战略的利益、合作方向与前景

进入新世纪,在俄罗斯的外交战略中亚太地区的地位在不断上升。俄罗斯大部分国土位于亚洲,所以在利用外交手段维护国家领土安全,并为本国东部地区的经济发展创造有利外部条件的同时,提升俄罗斯在亚太地区的影响力,是俄罗斯实施亚太战略的主要目标与利益所在。目前,俄罗斯与亚太地区的合作主要体现在能源、交通运输、粮食和安全保障等领域。但由于受俄罗斯东部地区的经济发展水平,以及俄罗斯参与亚太合作的矛盾心理,特别是与区域内各大国之间的关系等多方面因素的影响,俄罗斯与亚太关系的发展缺乏稳固的基础,进一步发展面临制约。     

现代性与世俗化理论探源——伊斯兰教个案研究

现代性以及现代化与世俗化的关系,这一西方性话语最早是在西方被提出并从多角度进行理论诠释和反思。总体来看,伊斯兰教无论是宗教本身还是其相对应的社会的现代化均呈现出二元化的发展态势,即传统与现代的二元共存。存在于伊斯兰教内部的"理性化"进程从来没有中断过,但是到目前为止,其真正面貌并没有完全浮出水面。人们更希望面临现代世俗主义影响的伊斯兰教能在实践中体现出其能量和活力,这种以实际行动的方式对现代性所作的有力诠释是任何理论都难以做到的。     

Occurrence of contamination by controlled substances in Euro banknotes from the Spanish archipelago of the Canary Islands

The social problems of drug abuse are a matter of increasing global problem. Nowadays, international agencies need fresh methods to monitor trends of the use of illicit drugs. In this sense, small amounts of drugs are transferred to banknotes and they could be detected and quantified. An analytical procedure based upon extraction with organic solvent, liquid chromatography separation, and mass spectrometric detection allowed the identification of 21 drugs and metabolites in 120 used Euro banknotes collected in the Canary Islands (Spain). Most of the banknotes analyzed showed detectable drug residues (92.5%). Cocaine was the most frequently detected drug, present in approximately 90% of the samples. In addition, 75%, 35%, and 15% of the banknotes showed residues of amphetamine derivatives, opiates, and benzodiazepines, respectively. An average of three drug residues per banknote was detected. In summary, the presence of drug residues in banknotes could be useful as tracer for drugs prevalence.     

环渤海港口合作机制研究——以合作博弈理论为视角

我国新世纪区域政策的调整为环渤海港口群发展提供了重大机遇,加强港口合作成为环渤海经济社会发展的内在要求和必然趋势。本文以合作博弈理论为研究视角,探讨了环渤海港口合作的理论依据和合作的切入点。作为合作切入点,环渤海港口合作机制具有政府与企业双重参与、共同约束的性质,需要在市场原则下加紧创新协调沟通机制和利益分配机制。     

关于加强西部地区民办高校学生思想道德建设的几点思考

改革开放以来,随着国家对教育机制的改革,民办高校跨上了腾飞的道路。在社会主义市场经济条件下,人们的思想意识、价值观念、道德观念、生活方式、行为取向等都发生了巨大变化,然而,西部地区经济发展的滞后和信息的相对闭塞使得西部地区民办教育发展举步维艰,尤其是在学生思想道德建设方面,在这样一个文化交融交锋的时代,如何加强西部地区民办高校学生思想道德建设,成为摆在从事思想教育者面前的艰巨任务。

西南民族地区的边疆服务与美国的社会福音

抗战爆发后,在国民政府的政策许可和经费支持下,基督教会在西南民族地区开展了一场以医疗、教育等社会服务为主、传教为次的边疆服务运动。该运动虽然受到了美国"社会福音"运动的影响,然而由于社会环境的差别,两种社会运动在使命、目标和行动上显示出了巨大的差异。

香港媒体中的天津形象及对内地城市形象跨地区传播的启示

城市形象的跨地区传播,对城市发展具有重要作用。天津作为＂新领军城市＂,在香港媒体中的城市形象具有典型性。对2009年7月至2010年10月间《文汇报》涉津报道的统计分析表明,天津城市形象的跨地区传播是非常成功的,其经验对内地城市形象跨地区传播具有较强的借鉴意义。
