Sampling and statistical considerations for the Suchey–Brooks method for pubic bone age estimation: Implications for regional comparisons

Although the Suchey–Brooks (SB) system is currently the most widely used method for age-at-death estimation from the pubic bone, the system continues to evolve through stepwise improvements. Since the system was developed from a pubic bone sample derived mainly from North Americans, it is unclear how well it performs on populations from other continents. During the last decade, studies of the SB system on pubic bone samples from local populations in Europe and Asia have indicated regional differences in the relationship between age and pubic bone development. However, these studies have for the most part followed different research protocols, which make comparisons between their results less meaningful. It would be most useful if future regional analysis of the SB system were done in a rigorous and uniform fashion, following standard procedures. In this paper, sampling and statistical considerations are outlined that hopefully will help to standardize research on the SB system.     

论经济犯罪侦查信息

侦查学基础理论关注对侦查情报的研究,但是鲜有论及侦查信息,从概念指向而言,侦查信息和侦查情报不能等同。信息时代,深入研究侦查信息已经成为一种必然趋势。在经济犯罪侦查领域,研究经济犯罪侦查信息可以帮助侦查主体培养正确的侦查思维,帮助侦查主体树立信息意识和证据意识,帮助侦查主体灵活选择侦查模式,同时还可以正确引导侦查决策。深入研究经济犯罪侦查信息理论对于经济犯罪侦查实务工作也会产生影响,其集中体现在建立和完善经济犯罪侦查协作机制、建立经济犯罪情报系统和建立经济侦查专门队伍三方面。     

视频图像侦查中视频信息内容分析初探

视频信息内容分析是视频图像侦查的重要内容之一。围绕案件相关要素来搜寻和发现涉案的视频图像资料,能为视频信息内容分析提供良好的基础。然后紧密围绕涉案人员图像、涉案车辆图像、涉案物品图像进行分析,并将获取的相关信息应用与侦查实践。     

论内幕交易、泄露内幕信息罪中“非法获取人员”的认定——美国法的“信息泄露理论”与“盗用理论”在中国的适用

中国法将内幕交易、泄露内幕信息罪的主体规定为知情人员与非法获取人员,而关于非法获取人员的范围与认定标准等都欠缺详细的规定。依据立法规定,并参照外国法理论,非法获取人员应是指除内幕人员外,可以凭借与发行公司或内幕人员的关系而非法获得内幕信息的人员,或者利用非法手段取得内幕信息的人员。对非法知情人员,美国判例则创制出了＂信息泄露理论＂与＂盗用理论＂以规制该类人员的内幕交易责任。对内幕人员的配偶与直系血亲,中国法应明文规定其相关责任,并利用＂信息泄露理论＂进行规制,而对其他以非法手段获知内幕信息的人员,则不妨适用＂盗用理论＂以进行惩治。     

技术与社会的互构——以信息通讯技术在商村社会的应用为例

技术与社会的关系是一个重要命题。本文以产业和社会结构发生剧烈变化的商业农村为个案,探讨技术与社会的关系,研究发现固定电话与手机的应用深刻地影响了商村的经济生产,它们在应用中的悖论现象则表明技术亦受社会的型塑:当熟人社会瓦解,信任机制发生改变时,固定电话因其完备的管理制度被使用者赋予隐秘的社会内涵;商村产业特征及经营策略压缩了经营者的私人空间和时间,致其将手机定位于商业信息传递的工具;漂泊的打工者在封闭的空间中更加渴求交流,因而在手机使用上表现出更强烈的情感倾向。此外,本文还想强调是使用者发挥了主体性,穿梭于信息技术产品与社会结构之间,赋予信息技术产品以生动的社会内涵,从而形成了具有地方社会特色的技术应用情况。     

The effects of four different solvent vapours on the restoration of obliterated stamp markings from five different wooden surfaces

The stamp markings on wooden surfaces, which are placed on trees and products including antiques, indicate the status of trees and involve identifying data regarding the products. Such markings are obliterated either to facilitate illegal logging or to conceal product information. Despite the wide literature on the restoration of obliterated characters on metal and polymer surfaces, the recovery of defaced characters on wooden surfaces appears to be understudied. Several reference texts in the forensic marks’ examination literature suggest that water, water vapor, and alkaline solutions are useful in restoring the abraded markings on the wood. Since there does not seem to be any experimental study proving such success, this study aimed to fill this gap. This study conducted experimental research by using water, ethanol, ammonia, and chloroform to recover the scraped characters on samples obtained from walnut, beech, spruce, oak, and cedar trees. The cold-stamped characters, which were defaced at varying depths, were restored using vapor and liquid phases of four solvents. While the vapor phases of water, ethanol, and ammonia yielded good outcomes on all types of wooden surfaces, the liquid phases did not seem to be useful in the revisualization process. The response of the vapors, which varied between 62 and 220 s, depended on the type of wood. The restoration technique developed in this research offers the possibility of on-site usage, easy application, utilization of low-cost solvents, rapid recovery, and effectiveness on various wooden surfaces. Overall, the restoration methodology used in this research appears to be fruitful in retrieving identifying information on wooden samples.
