From naming to local color preference, the visual experience accumulation in Chinese red lies not just in the solitary and fossilized historical relics, but in a ceaseless and dynamic process of formation, recognition, conversion and transmission. Moreover, the symbolic constitution and ethnic identi cation of Chinese red exempli es historical accomplishments in local exchanges of artifacts, technologies, systems, and outlooks with foreign partners. Therefore, as part of the country's cultural heritage, Chinese red also encompasses two aspects, cultural integration based on its identification and artistic productivity with a focus on di erentiation.展开更多

Second, the formerly stable structural relationship between peripheral regions and central regions gradually grows uncertain. Third, the establishment of cyberized roads or the cyberized expansion of roads leads the advance toward a global connectivity where the virtual world closely interacts with the real world. After "the Belt" concept comes into being, the anthropologists must upgrade their research from previously established fixed-point perspective to a more extensive observation over the "Belt" or a wider range, while the concept of "the Road" encourages anthropologists to study the culture of the other half of the world, namely, to read the world history as a whole new picture from a Chinese or eastern point of view. It is necessary for anthropology to break the geological and cultural borders in the real world to extend its antenna to a more extensive range, which will also bring the "otherness" of this field to a more prominent and obvious play. It is inevitable that all human cultures are about to take a core standing in the Belt and Road Initiative.展开更多

Modern-day isotopic investigations on human remains have integrated the use of multi-isotope profiles (e.g. C, N, O, H, S, Sr, and Pb) as well as iso-topic landscapes ("isoscapes") from multiple body tissues (e.g. teeth, bone, hair, and nails) to predict possible region-of-origin of unidentified human remains. Together, data from various isotope analyses provide additional lines of evidence for human identification, including a decedent's possible region-of-birth, long-term adult residence, recent travel history, and dietary choices. Here, we present the basic principles of isotope analysis and provide a brief overview of instrumentation, analytical standards, sample selection, and sample quality measures. Finally, we present case studies that reflect the diverse applications of isotope analysis to the medicolegal system before describing some future research directions. As shown herein, isotope analysis is a flexible and powerful geolocation tool that can provide new investigative leads for unidentified human remains cases.展开更多

Forensic anthropologists looking to identify human remains study traits of the skeleton and any orthopedic devices present. In order to obtain a positive scientific identification, evi-dence that is both sufficiently unique to the individual and comparable to available ante-mortem data from that individual must be found. The increased availability of radiographs, scans and implants in recent decades has facilitated the identification process. When these records are unavailable, other techniques, such as craniofacial superimposition and facial approximation, can be employed. While these methods may assist the identification process, they are most useful for exclusion of certain individuals and gathering leads from the public. Forensic anthropologists have heavily relied on the skull and its complexities for identifica-tion – typically focusing on the frontal sinus and other unique traits. Post-cranial remains can provide important information about bone density, possible disease and other character-istics that may also be utilized. Techniques used to positively identify individuals are not limited to medicolegal death investigations, and have been useful in other legal contexts. In the future, a team approach, utilizing all the information gathered by multiple forensic scientists–including forensic anthropologists–will most likely become more common.展开更多

文摘Anthropologists are often the custodians of long-term unidentified human remains though their positions as curators of university or museum skeletal collections.Various factors decrease the solvability of these legacy cases including the passage of time,the loss of provenience for specific cases,and lack of documentation or case records.While anthropologists can contribute important information toward identification,it is often necessary to explore novel and cross-disciplinary strategies to resolve difficult cold cases.In long cold cases,the postmortem interval,in particular,may be difficult to estimate leading to further challenges in achieving identification.Modern advances in radiocarbon bomb pulse dating,isotope analysis,and actualistic studies have contributed to positive identification of unidentified human remains in some legacy cases,but may not be available to all forensic practitioners and law enforcement from resource-poor agencies.Pooling resources,as well as collaborating with professionals outside of forensic anthropology,is a useful strategy to pursue when anthropological methods are exhausted.The case study presented here demonstrates a collaborative approach between forensic anthropologists,forensic genetic genealogists,and law enforcement in a century-old homicide.The dismembered and mummified parts of a male body were recovered in a remote cave in 1979 and again in 1991.Despite forensic anthropologists creating and updating the biological profile over the decades from recovery to present,no identification was made until the application of forensic genetic genealogy(FGG)to the case in 2019.New interpretations of bone microstructure and trauma analysis are presented for the case,alongside the historical documentation and“proof of life”evidence used by the genealogy team.A review of the FGG methods underscores the challenges in this case(e.g.significant endogamy,multiple aliases used by the victim)and the steps taken toward resolution.Ultimately,a combined anthropology and genealogy approach resulted in a confirmed identity for a man who was murdered in 1916.
文摘Estimation of age represents a central focus of forensic anthropological analysis of human skeletal remains and of the living. Advances registered in recent research include the topics of taphonomic impact, new anatomical areas of interest, histology, population variation, the dental pulp chamber, technology, mathematical approaches, biochemical analysis and techniques specifically targeting the living. This article reviews the historical development of age estimation methods and considers likely future directions.
