司法孢粉学在司法鉴定中的应用

司法孢粉学是法庭科学的一门分支学科,孢粉检验可为推断嫌疑人与犯罪现场的关联、案件发生时间、毒品来源等提供重要信息。在新西兰、英国、美国等国家,孢粉检验已在多起案件的侦破中发挥了重要作用,其他国家近年来也陆续开展了相关的应用研究。本文综述了近50年来司法孢粉学的典型案例,介绍了该学科的历史和现状,探讨了其未来的研究重点和发展方向,以期提高人们对该学科的全面认识,加强今后在司法鉴定中的应用

Plant names as traces of the past in Shuiluo valley, China

This study presents results of interdisciplinary fieldwork in Southwest China by a team of linguists and ethnobotanists. It is based on a comparative analysis of 70 common plant names in five Tibeto-Burman languages spoken in Shuiluo Valley. The discussion focuses on (a) names for locally important field crops and (b) plant names that are shared between two or more languages. We make a preliminary stratification of cognates and loanwords; we advance hypotheses about the sources of loanwords; and we assess the distribution of loanwords against the background of the existing historical and linguistic accounts of the studied languages. The observed patterns shed light on the complex migration history in the area and identify a group of plant names which may originate in a linguistic variety which was once (or still is) native to Shuiluo
