ABSTRACTMorphometric analysis offers an alternative or augmentation to traditional archaeobotanical methods to address differences within and between plant species and their remains, refining and enhancing taxonomic resolution. Morphometrics, the measurement of size and shape, and the multivariate statistical analysis of generated quantitative variables, have long played a major role in biological research, including plant taxonomy and systematics, although its application in archaeobotany is relatively recent. Over the last few decades, there has been an increasing interest in the use of morphometrics for analysing a varied range of archaeological plant materials (mainly seeds, pollen, phytoliths, and starch grains). In particular, morphometrics have contributed to the study of the domestication and spread of many cereals world-wide, as well as that of other taxa including legumes, underground storage organs (USO), and fruits (such as olives, grapes, and dates). This paper reviews current methodologies, recent applications, and advances in the use of morphometrics in archaeobotanical research, discusses its role in exploring major research questions, and suggests possible future directions for its use. 相似文献

Within the last 30 years, geographical information systems (GIS) have been used increasingly in the training of geographers. On the basis of the philosophy of technology and instrumental genesis, we sketch how the use of instruments interacts with learning processes and outline how this can be studied. We empirically analyse students' learning processes and the influences of teaching practice in an introductory course in GIS. We show that students have different strategies for creating their personal instrument for spatial thinking and how teaching interacts with the students' learning processes. Finally, we discuss how GIS may gradually alter future professional development of geographers. 相似文献

The author's primary aim in what follows is to fully articulate Chantal Delsol's critique of late modern universalism as an attempt to depoliticize the individual for the sake of replacing politics with morality. The result of this depoliticization is a quasi-pantheistic cosmopolitanism that not only effectively denies the significance of individuality, despite rhetorically lionizing it, but also undercuts the freedom of individual conscience that makes moral choice possible. Genuine political prudence and moral judgment are subsequently replaced by the rigid exactitude of a technocratic analysis that reintroduces the "clandestine ideology" it was, despite protestations to the contrary, intended to eliminate. The unhappy paradox produced by the attempt to replace the necessary limitations of political judgment with the universality of a priori moral decree is that a new set of culturally and historically idiosyncratic political attachments are surreptitiously introduced beyond the pale of reasonable debate and disagreement. Delsol's measured response is not a precipitous rejection of universalism as such but a rehabilitation of it that recaptures the Christian moral realism at its core. 相似文献

Deqen, honored as “Shangri La”,is located in the area where three rivers meet to form one in the Henduan Mountains straddling the borders of Yunnan, Sichuan and Tibet. The Deqen Tibetan Ethnic Group Autonomous Prefecture, founded in September 1957, is the only Tibetan autonomous prefecture in Yunnan Province but one of 10 in the 相似文献
