Digital processing of images can be used to analyse ceramic pastes, contributing in this way to the discrimination of ceramic types. The method involves several stages of analysis: digitization of images of ceramic pastes, pre‐processing of the images, particle segmentation, calculation, quantification and classification of the particle sizes. This procedure uses interactive algorithms of segmentation of images and grain size analysis derived from mathematical morphology theory. To prove the efficiency of the method, we processed digital images of polished thin sections of ceramic samples of Cypriot wares from the Late Bronze Age (1550–1450 bc ) and their Egyptian reproductions. Such groups have been previously analysed by optical microscopy, XRD, XRF, ICP–MS and EPMA. The results of the analysis were able to discriminate between these two different wares. 相似文献

This discussion started on the WAC listserv when I objected on 8 April 2007 to a short message sent by Claire Smith on the previous day. She had been announcing that her colleague “Heather Burke and [are] putting together a list of important non-Anglo archaeologists” and was asking whether “anyone has any recommendations” for that list and, if so, whether they would email her off list. I objected strongly. This paper explains why. In doing so I am describing the degree of complexity language use has acquired in the contemporary world with old linguistic maps quickly become obsolete. To insist that English is simply the lingua franca of academic discourse is to ignore that complexity. The wide use of English as an academic lingua franca means in practice that there are very strong asymmetries not only in individual archaeologists’ abilities to express themselves competently and confidently in that language but also in what is considered appropriate or possible to express. For a language is not simply a random code with which anything might be said to anybody. Language, and the conventions that govern how a given language is to be applied, influences to a large extent even what is a sensible thing to say in a given context. Language use in archaeology is not about translating the same archaeology into different languages but about translating between different archaeologies and associated cultural practices including languages. The only sensible way forward is for WAC to promote among its members the learning of more languages—which is something the vast majority of “non-Anglo” archaeologists already knows and accepts as a fact of life. We do not need lists of “non-Anglo” archaeologists that are considered worth reading about in English, but more archaeologists being able to appreciate the work of colleagues in its original language. In conclusion I urge exclusively Anglophone archaeologists to please stop finding excuses for learning foreign languages. 相似文献

AbstractThin carpets of worn and abraded sherds frequently occur over many square kilometers of ground around archaeological sites in the Middle East. Sherd scatters around three sites in Iran, Oman, and Syria are described. It is suggested that the artifacts arrive as a result of transport of compost or manure incorporating urban refuse from the city to the nearby fields. The sherd scatters occupy a zone of between 3 and 6 km. radius around the sites, and this belt, it is suggested, corresponds to the inner zone of intensive cultivation. The data presented give some empirical support to concepts of site-catchment analysis and also suggest that the use of manure in agriculture can be traced back to at least the 3rd millennium B.C. 相似文献

周原现代地貌考察和历史景观复原 总被引:2,自引:0,他引:2
周人由豳地徙至岐山 ,当时应是湿润—半湿润气候。周人将定居处选择在岐山南麓的山前冲积扇地带 ,而不是如新石器时代先民那样选择在诸沟汇合处的黄土塬上 ,表明有将这里建成政治中心的意图。夏商周三代的崛起 ,都与其不断追求生境优化直接相关 ,这对于探讨中国文明起源的动因具有重要意义。 相似文献

This piece adopts a genealogical approach to the emergence of “neo-Shamanism” as a “spiritual” practice. It argues that the work of Freud and Durkheim collapsed the dichotomy between “primitive” and “civilized” which characterized nineteenth-century evolutionist anthropology. Neither Freud nor Durkheim embraced the consequences of this collapse, and while Bataille attempted to do so, his application of “Shamanism” to modern self-governance was constrained by the terms of the Freudian/Durkheimian framework. Jung did embrace this collapse, positing a universal equivalence between religious forms and psychological processes, and this epistemic shift permitted his interlocutors, Levi-Strauss and Eliade, to inaugurate the discursive frameworks which made “neo-Shamanism” thinkable as an ethical practice for contemporary Westerners. Analyses which suggest that “neo-Shamanisms” are rediscoveries of a primal “spirituality” write from within this framework, neglecting the contingency of historical change, the creativity of anthropological appropriations and the politics of knowledge. 相似文献

本文的着眼点在于对晏几道词中“追忆”手法运用的探讨。从小山词中大量的“追忆”内容入手,分析了追忆内容的分类和追忆中多种手法的运用,以及其艺术特点和艺术效果,最后论述了晏几道钟情于“追忆”的原因所在,即他与现实生活的隔膜及由此形成的孤傲性格和狭窄的生活限制,肯定了“追忆”手法在小晏词中的重要地位和作用。 相似文献

为了科学鉴别同性合葬墓中死者是否血亲、异性合葬墓中死者是否夫妇,日本体质人类学家和考古学家合作利用牙齿具有较高遗传性、恒齿形态不变、成人和儿童可以直接比较的特点,发明了通过比较死者之间齿冠测量值Q型系数来判断他们是否血亲的方法,这个方法被证明可以有效地判断古人骨是否血亲。列举的实例演示了如何把齿冠测量值与考古背景资料结合起来分析古人骨是否血亲及其关系的具体做法。 相似文献

This paper deals with the design of general classes of dynamic spatial interaction models. On the basis of a general (well-behaved) multiperiod objective function and of a dynamic model representing the evolution of a spatial interaction system, an optimal control model is constructed. Particular attention is given to the equilibrium and stability conditions. It turns out that it is possible to identify steady-state solutions for a dynamic spatial interaction model. Furthermore, it can also be demonstrated that the entropy model is a specific case of this spatial interaction system. A simple illustration for urban dynamics is given as well. 相似文献
