浅析纸钞的公众防伪设计

钞票是国家名片,各国为了防范伪造都在钞票上采用了大量防伪技术。钞票的防伪技术一般分为公众防伪、专业防伪和专家防伪三个层次。公众防伪特征是公众无需使用特殊设备就能鉴别钞票真假的主要手段,也是假币犯罪分子突破的重点。为了应对制假技术的提高,增强货币的防伪能力,中国人民银行和欧美等国央行也在不断对钞票进行改版提升,将最新的防伪技术应用到钞票中,同时加大宣传力度,提高普通民众对钞票防伪点的识别能力。本文调研了欧美等国央行在钞票防伪技术提升与防伪点的公众识别方面的研究,分析了新版人民币与部分国家和地区最新发行的纸质钞票的公众防伪特征,对比了不同纸钞的公众防伪特点,结合纸钞防伪设计分析,从更新钞票防伪设计、加强公众宣传等方面,为防范假币提出了建议。

刍议刑事判例制度

刑事判例是指最高审判机关或者上级审判机关对同级或者下级审判机关在对刑事案件适用刑法过程中所形成的有效判决进行识别、整理、汇编而形成的对同级或者下级审判机关在办理同类案件时具有事实上、业务上、制度上普遍约束力的指导、借鉴、援用和解释法律作用的范例。刑事判例的产生、运用过程中所形成的系统就是刑事判例制度,包括判例的识别、适用判例的原则、规则和方法、判例集的汇编、公布以及援用等。该制度对刑法和司法解释的不足起弥补作用并且是实现罪刑法定原则的重要途径。它依托制定法,除没有法源外具有判例法的其他特点。     

A quantitative method for estimation of volume changes in arachnoid foveae with age

Age-related changes of arachnoid foveae have been described, but objective, quantitative analyses are lacking. A new quantitative method is presented for estimation of change in total volume of arachnoid foveae with age. The pilot sample consisted of nine skulls from the Palmer Anatomy Laboratory. Arachnoid foveae were filled with sand, which was extracted using a vacuum pump. Mass was determined with an analytical balance and converted to volume. A reliability analysis was performed using intraclass correlation coefficients. The method was found to be highly reliable (intraobserver ICC = 0.9935, interobserver ICC = 0.9878). The relationship between total volume and age was then examined in a sample of 63 males of accurately known age from the Hamann-Todd collection. Linear regression analysis revealed no statistically significant relationship between total volume and age, or foveae frequency and age (alpha = 0.05). Development of arachnoid foveae may be influenced by health factors, which could limit its usefulness in aging.

被伐树木整体分离痕迹检验中特殊特征和固有特征的运用

被伐树木形成的整体分离痕迹有其独特性,反映出特有的规律。本文介绍了在盗伐林木案件中,运用整体分离痕迹检验原理、方法,检验被伐树木分离面、分离缘的形态,检验其凸凹断茬特征、虫眼特征、裂纹特征、空心特征等特殊特征以及节子特征、年轮特征、木射线特征、树皮纹理特征等固有特征。特别是在两对应的锯断面之间木质完全缺失情况下,综合运用上述特征有针对性地检验,解决了部分被伐树木整体分离痕迹检验中分离痕迹能否作为同一认定证据、分离体是否原为同一整体的问题。文中所述对被伐树木上的特殊特征和固有特征的研究和运用,拓宽了被伐树木整体分离痕迹检验中特征标记的范围,为丰富被伐树木整体分离痕迹的检验方法提供了参考。     

Weight of authorship evidence with multiple categories of stylometric features: A multinomial-based discrete model

This study empirically demonstrates the efficacy of a two-level Dirichlet-multinomial statistical model (the Multinomial system) for computing likelihood ratios (LR) for linguistic, textual evidence with multiple stylometric feature types with discrete values. The LRs are calculated separately for each feature type, namely, word, character and part of speech N-grams (N = 1,2,3), which are combined as overall LRs through logistic regression fusion. The Multinomial system’s performance is compared with that of a previously proposed system with the cosine distance (the Cosine system) using the same data (i.e., documents collated from 2160 authors). The experimental results show that: (1) the Multinomial system outperforms the Cosine system with the fused feature types by a log-LR cost of ca. 0.01 ～ 0.05 bits; and (2) the Multinomial system is more advantageous in performance with longer documents than the Cosine system. Although the Cosine system is more robust overall against the sampling variability arising from the number of authors included in the reference and calibration databases, the Multinomial system can achieve reasonable stability in performance; for example, the standard deviation value of the log-LR cost becomes lower than 0.01 (10 random samplings of authors for the reference and calibration databases) with 60 or more authors in each database.
