Detection of Diatoms by a Combination of Membrane Filtration and Transparentness,

Diagnosis of drowning remains a difficult issue in current forensic sciences. A large number of diatoms were lost by removing the supernatant after centrifugation in the conventional forensic diatom test. We developed a novel membrane filtration method to enrich diatoms from samples. A new solution using different ratios of acetic acid and eugenol is prepared to make the membrane transparent. These processes allow the diatom‐containing membrane to be visualized and identified easily by light microscopy. The tissues contaminated by water rich in diatoms were detected by the new method for the recovery of diatoms. Eleven drowning cases were analyzed by both the new method and the conventional method to compare the sensitivity of both methods. The recovery of the novel diatom test method was 54.2 ± 23.1%. The positive rate of the novel method has been proven to be superior to the conventional method in the diagnosis of drowning.     

Vertical Lip Position and Thickness in Facial Reconstruction: A Validation of Commonly Used Methods for Predicting the Position and Size of Lips

This study examined several methods used to estimate oral fissure position, lip margin position, and lip thickness recommended by Angel, George, Lebedinskaya, Taylor, Wilkinson et al., Balueva and Veselovskaya. A sample of 86 lateral head cephalograms of adult subjects from central Europe were measured and the actual and predicted dimensions were compared. The best estimation for oral fissure position was “opposite the lower ¾ mark of maxillary incisors” (error of 1.3 mm). Upper lip margin was predicted best by “upper ¼ mark of maxillary incisors” (error of 1.7 mm), and lower lip margin by “cementum‐enamel junction of mandibular incisors” (error of 2.3 mm). The regression equations of Wilkinson et al. displayed least error (1.3 mm and 1.8 mm, respectively) for upper and lower lip thickness, and method of George (error of 3.4 mm) for total lip thickness.     

人隐瞒信息状态下多通道事件相关电位的研究

目的采用隐瞒信息测试(concealed informationtest,CIT)模式和多通道事件相关电位(event related potential,ERP)技术,对人类大脑在不同刺激下各脑区域活动情况和活跃程度进行对比,从神经电生理学层面揭示CIT模式隐瞒信息状态下视觉刺激人类大脑认知相关脑功能区特征。方法参考犯罪知情测试模式(GKT)的CIT模式,选用传统扑克牌,对17名被试人员进行视觉刺激,包括:靶、探测、无关和中立刺激,获得29通道ERP波。结果靶、探测和无关刺激平均按键反应时间:775ms、774ms和720ms;探测和无关刺激各通道P300峰潜伏期配对t检验,有统计学意义(P0.05)的通道有4个;探测和无关刺激各通道P300平均波幅(400~700ms)进行配对t检验,有统计学意义(P0.05)的通道有19个。结论隐瞒知晓信息是一个由多个脑功能皮质共同完成的复杂过程,与诚实反应抑制有密切关系,与额叶前部和上部皮质、前扣带回皮质(ACC)和缘上回等脑功能皮质特异相关。     

Social Media and E-professionalism in Child Welfare: Policy and Practice

The professional child welfare literature offers little guidance to child welfare managers and agency policy makers about the use of social media to search for or communicate with clients. Ethical social media use relies upon e-professionalism, defined as the professional identity established by workers through the way they utilize digital communications. This article offers considerations for standards of e-professionalism in child welfare policy and practice. Specific considerations are outlined for social media policy and practice scenarios are offered, which can be used to prompt agency discussions with child welfare workers.     

信息技术与课程整合的现实困境与实践探索——基于高职英语教师的视角

当前,我国教育进入了教育信息化发展的新时期。教育信息化的重心转向以课程改革为导向,教师的信息化教学设计培训为核心,推进课程与信息技术整合的深入发展。高职公共英语课程的信息化教学设计过程,是提高高职院校公共英语课程教学效果的有效途径,也对各级公共英语的教学设计起到示范和参考作用。     

论现代科技对侦查的影响

现代科技对侦查的影响是全面而深刻的。对侦查的对象——刑事犯罪的影响体现为：在手段方面进行科技化改造,在领域方面促使其进一步增大;对侦查能力的影响体现为对侦查技术的进一步提升及对侦查理念的进一步拓展;对侦查法治的影响体现为侦查法治的文明化程度不断提升与现代科技为侦查法治带来了一些争议性问题;对侦查学的影响体现在侦查学和刑事技术学的融合和分化的发展过程。在现代科技的语境下,刑事侦查要辩证地对待现代科技的影响,促进侦查能力、侦查法治和侦查学的发展。     

唐代试判之起始与情状初探

唐代判文也是唐代文学的一部分,它是唐代吏部铨试的一种应试文体。由于它不仅有实用性的要求,而且有美的要求,好的判文必须是文理与辞采都具备,于是它也就同时具有了文学性。梳理唐代试判的发展状况,从文学的角度加以审视,认识其文学价值,以及它对后世考试文学的影响,也是唐代文学研究中应有之义,并且有着比较重要的文学史认识意义。     

单亲案的亲权概率的计算及认定标准

确定单亲案的亲权概率计算方法和认定标准。用多基因座DNA分析方法和计算多基因座累积平均非父排除率计算公式。检测8个以上的DNA多态性基因座,在等位基因的遗传不违反孟德尔规律的前提下,父权概率都可达到或超过0.9990的标准;对不存在亲生关系的案例,在用本方法时,都有3个或更多的基因座的等位基因遗传违反孟德尔规律。对单亲案的亲权鉴定,检测的多态性基因座要在8个以上。在肯定亲生关系时,父权概率要达到或超过0.9990;在否定亲生关系时,必须有3个以上或更多的基因座违反孟德尔遗传规律。     

金融全球化、全球金融治理改革与国际金融安全*——基于信息科技革命的视角JP〗*

从本质上说,金融业是一种“信息密集性”或“信息敏感性”产业,对于金融全球化而言,信息技术进步具有特殊重要的意义。在信息科技革命引领和推动下,互联网与金融业相互融合,掀起了人类历史上第二次大规模的金融全球化浪潮。当代金融全球化迅猛发展对国际金融安全产生了重大而深远的影响,新一轮大规模金融全球化、国际金融体系的巨大变化以及由此而形成的新的国际金融格局与既有的全球金融治理框架之间的均衡逐渐被打破,既有的全球金融治理框架越来越难以适应信息科技革命条件下金融全球化发展和维护国际金融安全的要求。为更好地适应当代金融全球化条件下建立新的国际金融公共秩序,更好地维护国际金融安全的需要,以2008年全球金融危机爆发为契机,国际社会揭开了全球金融治理改革的大幕。在国际金融体系和全球金融治理框架处于大变动和寻求新均衡的背景下,中国应抓住有利时机,以更加积极、主动的姿态参与和推动全球金融治理改革,坚持命运共同体理念,遵循责任、权力相一致和平衡的原则,倡导在全球金融治理中加强互联网的运用,为维护国际金融安全做出更大贡献。
