Using PMCT of Individuals of Known Age to Test the Suchey–Brooks Method of Aging in Victoria,Australia

The estimation of an individual's age at death plays a critical role in the investigation of unidentified human remains. The Suchey–Brooks method, which involves the analysis of degenerative morphological changes in the pubic symphysis, is currently widely used to estimate age in adults. This study tested the applicability of the Suchey–Brooks method on a contemporary adult Australian (Victorian) subpopulation by observing three‐dimensional volume‐rendered postmortem computed tomographic (PMCT) reconstructions of the pubic symphysis of 204 individuals aged 15–100 years. Results showed the method was reliable for females (85% correct allocations) but not for males (67% correct allocations). It is therefore recommended that extreme caution be used when applying the Suchey–Brooks method for estimating age at death of an individual in this subpopulation from PMCT images. The results suggest further investigation into alternate age estimation methods is required.     

对下调法定最低刑责年龄的省思

此次刑法修正案(十一)对最低刑事责任年龄进行下调,可以在很大程度上避免一部分已满12周岁未满14周岁的未成年人倚仗法律保护肆意实施危害行为的"钻法律之空子"的情况发生,能够有效提升法律的威慑力,使公众免受"12岁恶魔"的伤害。在作为调整对象的低龄未成年人一侧,最低刑责年龄的下调意味着他们必须为自己的不法行为承担责任、付出代价。戴上这只法律"金箍"的未成年人将不得不在法律的框架内保持自身行为的检点合法。当然,虽然法律对最低刑事责任年龄进行了下调,但犯罪未成年人仍然需要在"教育为主、惩罚为辅"的矫治环境中得到救赎,既不能"一放了之",也不能"一关了之"[1]。在"疏"与"堵"并行的同时加强相关法律制度的衔接,使低龄未成年人可以在一个相对完善的制度设计中树立起对法律以及他人权益的敬畏之心。     

数字社会治理的权利逻辑:以个人信息权为中心

以信息技术为核心的数字社会迅速发展,促进多元主体信息交流和资讯共享,给个人信息保护带来挑战。作为数字社会公民身份的基本表征,个人信息权既是数字公民实现全面自由发展的先决条件,也是防范和控制数字权力异化的重要工具。实现数字社会个人信息权保护的价值追求,国家立法机关应秉持作为宪法价值核心的人格尊严进行立法,明晰个人信息权的规范内涵与保护机制;行政机关应遵循权力法定原则,严格基于法律保留、公共利益和比例原则处理和使用个人信息,并建立专门的个人信息权保护的监管机构;司法机关应通过法律适用和司法解释对被侵犯的个人信息权提供及时司法救济,填补法律漏洞,实现数字社会个人信息权保护的制度正义目标。     

Frequency of Parental Violence Against Children in Chinese Families: Impact of Age and Gender

The present study examines the impact of child and parent gender on parental violence across age span of children and their parents in Hong Kong Chinese families. A randomly selected community sample of 1,019 households was surveyed. Results indicate that, in general, boys experience more frequent parental violence than girls and mothers engage in more violent behaviors against their children than fathers. Parental violence shows a curvilinear pattern with age of children, peaking at age 8 for boys and age 3 for girls. There is a pattern of declining frequency of parental violence as parental age increases across child gender. Fathers exhibit an inverted U pattern of violent behavior against their children, with a peak around age 31–40, while mothers have a steadily declining trend until age 46. Separate parental violence indices are constructed for boys and girls.     

Forensic integrity verification of video recordings based on MTS files

Digital video is used in criminal trials as evidence with legal responsibility because video content vividly depicts events occurring at a crime scene. However, using sophisticated video editing software, assailants can easily manipulate visible clues for their own benefit. Therefore, the integrity of digital video files acquired or submitted as evidence must be ensured. Forensic analysis of digital video is key to ensuring the integrity of links with individual cameras. In this study, we analyzed whether it is possible to ensure the integrity of MTS video files. Herein, we propose a method to verify the integrity of MTS files encoded by advanced video coding high definition (AVCHD), which is frequently used for video recording. To verify MTS file integrity, we propose five features. Codec information, picture timing, and camera manufacture/model are modified AVI and MP4-like format video verification features. Group of pictures and Universally Unique Identifier patterns were specifically developed for MTS streams. We analyzed the features of 44 standard files recorded using all recording options of seven cameras. We checked whether integrity can be validated on unmanipulated videos recorded in various environments. In addition, we considered whether manipulated MTS files edited in video editing software could be validated. Experimental results show that all unmanipulated and manipulated MTS files with known recording devices were discriminated only when all five features were checked. These results show that the proposed method verifies the integrity of MTS files, strengthening the validity of MTS file-based evidence in trials.     

Pulp volume quantification methods in cone-beam computed tomography for age estimation: A critical review and meta-analysis

The secondary dentin deposition that occurs after the tooth formation process results in a decrease in pulp cavity volume in adolescents and adults. The purpose of this critical review was to correlate pulpal and/or dental volume on cone-beam computed tomography (CBCT) with chronological age approximation. A subobjective was to investigate which methodology and CBCT technical parameters would be most appropriate to evaluate this correlation. This critical review followed the PRISMA guidelines, and it was conducted by a search through PubMed, Embase, SciELO, Scopus, Web of Science, Cochrane Library databases, as well as gray literature. Primary studies that used pulp volume, or pulp chamber to tooth volume ratio measured using CBCT were included. Seven hundred and eight indexed and 31 non-indexed records were identified. A qualitative analysis was performed including 25 selected studies with a total of 5100 individuals, age ranging from 8 to 87 years without sex predilection. The most used method was pulp volume/tooth volume. CBCT voxel size ranged between 0.09 and 0.5. Manual segmentation associated with threshold algorithms was used in most of the studies. Correlation between the pulp volume/tooth volume ratio was moderate: −0.66 for the upper central incisors, −0.59 for upper canines and −0.56 for lower canines. High heterogeneity was observed among the studies. It is concluded that pulp volume should be used with caution in age estimation. Evidence supports the preferable use of upper incisors with pulp volume/tooth volume ratio for age estimation. There is not enough evidence that voxel size interferes in age estimation by pulp volume.     

Study on the standard components of digital forensics laboratory

Recently, digital forensics has become increasingly important as it is used by investigation agencies, corporate, and private sector. To supplement the limitations of evidence capacity and be recognized in court, it is essential to establish an environment that ensures the integrity of the entire process ranging from collecting and analyzing to submitting digital evidence to court. In this study, common elements were extracted by comparing and analyzing ISO/IEC 17025, 27001 standards and Interpol and Council of Europe (CoE) guidelines to derive the necessary components for building a digital forensic laboratory. Subsequently, based on 21 digital forensic experts in the field, Delphi survey and verifications were conducted in three rounds. As a result, 40 components from seven areas were derived. The research results are based on the establishment, operation, management, and authentication of a digital forensics laboratory suitable for the domestic environment, with added credibility through collection of the opinions of 21 experts in the field of digital forensics in Korea. This study can be referred to in establishing digital forensic laboratories in national, public, and private digital forensic organizations as well as for employing as competency measurement criteria in courts to evaluate the reliability of the analysis results.     

Scopic valuations: how digital tracking technologies shape economic value

How do market actors in the contemporary economy make decisions when they are uncertain of the value of what is being traded? To answer this question, this paper analyses the changing temporal and spatial orientation of economic valuations in increasingly digitalized economies, in which markets can no longer be understood as locally bound and closed sites of valuation and exchange. Drawing on ethnographic material from the fishing industry, the paper shows how digital tracking technologies link and synchronize auction markets with real-time information on fishing activities. Hence, ‘scopic media’ such as chart plotters and computer screens are not only deployed by skippers to monitor one another, but are also used as valuation devices that recontextualize local knowledge for the purpose of coping with economic uncertainty. As a consequence of this panoptic valuation regime, fishermen control their virtual identities by disciplining harvesting practices according to their buyers’ expectations.
