Discrimination of Geographical Origin of Asian Garlic Using Isotopic and Chemical Datasets under Stepwise Principal Component Analysis

Isotopic compositions of δ²H, δ¹⁸O, δ¹³C, and δ¹⁵N and concentrations of 22 trace elements from garlic samples were analyzed and processed with stepwise principal component analysis (PCA) to discriminate garlic's country of origin among Asian regions including South Korea, Vietnam, Taiwan, and China. Results indicate that there is no single trace‐element concentration or isotopic composition that can accomplish the study's purpose and the stepwise PCA approach proposed does allow for discrimination between countries on a regional basis. Sequentially, Step‐1 PCA distinguishes garlic's country of origin among Taiwanese, South Korean, and Vietnamese samples; Step‐2 PCA discriminates Chinese garlic from South Korean garlic; and Step‐3 and Step‐4 PCA, Chinese garlic from Vietnamese garlic. In model tests, countries of origin of all audit samples were correctly discriminated by stepwise PCA. Consequently, this study demonstrates that stepwise PCA as applied is a simple and effective approach to discriminating country of origin among Asian garlics.     

Diagnosing Crime and Diagnosing Disease‐II: Visual Pattern Perception and Diagnostic Accuracy

Previously, we reviewed how general cognitive processes might be susceptible to bias across both forensic and clinical fields, and how interdisciplinary comparisons could reduce error. We discuss several examples of clinical tasks which are heavily dependent on visual processing, comparing them to eyewitness identification (EI). We review the “constructive” nature of visual processing, and how contextual factors influence both medical experts and witnesses in decision making and recall. Overall, studies suggest common cognitive factors uniting these visual tasks, in both their strengths and shortcomings. Recently forensic sciences have advocated reducing errors by identifying and controlling nonrelevant information. Such efforts could effectively assist medical diagnosis. We suggest potential remedies for cognitive bias in these tasks. These can generalize across the clinical and forensic domains, including controlling the sequencing of contextual factors. One solution is an agnostic primary reading before incorporation of a complete history and interpretation.     

Controversial Suicide Case Using a Submachine Gun with a Sound Suppressor—The Need of Team Work of Forensic Chemistry and Firearm Examiners

Evidence materials in a presumed suicide case were studied by a firearm examiner and a forensic chemist. The victim's body with double gunshot wounding in his forehead, a machine gun in the sustained fire mode with a silencer, and four cartridge cases were found. Examinations of the evidence, the case file studies, and experiments dedicated to the case were carried out. Relationships between the placement of cartridge cases and the gun were established using a fast camera. The distributions of gunshot residues on the evidence materials and within the comparative gunshot patterns were studied by means of optical and electron microscopy, X‐ray microanalysis, and infrared spectroscopy. The shooting distance was assessed to be 30 cm or more, whereas the greatest distance that could have been achieved by the victim himself was about 11–13 cm. The obtained results supported the version of homicide rather than suicide.     

应用枕骨大孔面积判定性别的研究进展

性别是个体识别的主要生物学指标之一,是法医学鉴定不明骨骼残骸的重要初始步骤。枕骨大孔因其解剖学位置的隐匿性、形态学的稳定性、性别与种族的差异性成为法医学性别判定的研究热点,其中枕骨大孔面积是枕骨大孔区域中进行性别判定准确率较高的指标之一。本文以枕骨大孔面积为主要研究对象,就国外学者通过干颅骨样本、CT影像、CBCT影像测量枕骨大孔面积判定性别的方法进行总结,对国内应用枕骨大孔面积进行性别判定研究提供参考。     

Identity and Foreign Policy: Canada as a Nation of the Americas

Using Canada's relations with the Americas as a case study, this article seeks to better understand the link between identity and foreign policy. It argues that there is a gap between the Canadian government's recent efforts to construct a state identity increasingly turned toward the Americas and Canadians' national identity as it is expressed through public opinion. It concludes that the most plausible explanation for this gap probably has to do with Canada's European cultural heritage. The analysis shows that the projection of national identity into foreign policy is a much more complex process than the projection of state identity.     

Development Dynamics of Chinese Resource‐Based Investment in Peru and Ecuador

This article analyzes the developmental impact of two of the earliest investments made by Chinese companies in South America, the Shougang Corporation's mining activities in Peru and Andes Petroleum's oil extraction operations in Ecuador. The article draws attention to the importance of contextualizing and disaggregating instances of Chinese resource‐based investment in order to adequately grasp the complexity of processes that are contingent to particular regimes of natural resource governance, companies' backgrounds, and the strength and nature of local reactions, among other factors. It thereby encourages a critical examination of Chinese investment in South America that explores how the characteristics of that investment are reshaped by the long and contested histories of resource extraction in the region, the promotion of and resistance to particular visions of development, the agency of multiply situated and complex actors, and the wider transnational production networks in which resource extraction processes are embedded.
