The carbon (δ13C) and nitrogen (δ15N) isotope ratios of human bone collagen have been used extensively over the last 40 years to investigate the diet of past populations. It has become apparent that bone collagen can give an unreliable temporal dietary signature especially in juveniles. With higher temporal resolution sampling of collagen from tooth dentine, it is possible to identify short-term changes in diet previously invisible in bone. This paper discusses the inherent problems of using bone collagen for dietary studies and suggests better sample choices, which can make our interpretations more robust, using breastfeeding and weaning as an example.  相似文献

It is late afternoon, and two figures are seen walking slowly along a path that leads through laurel, olives, and vines towards white Colonus, earth's loveliest, where the nightingales liquid notes most haunt the darkness of green glades. They are deep in conversation, yet move with steady, purposeful strides towards an inn that cools its crisp Demesticha in the flowing waters of a spring.  相似文献

历史上的异质文化输入对艺术的发展都有促进作用,敦煌艺术正是异质文化和本土文化碰撞融合的结果。在当代艺术语境中,敦煌艺术具有文化融合的典范作用和对传统文化冈子继承的双重身份。敦煌学研究的日益深入和多学科交叉研究的日趋成熟,为敦煌艺术研究的转型搭建了一个有益的平台。存中同当代艺术发展的进程中,西方现代主义艺术思潮之后的本土文化回归是目前面临的主要问题。敦煌艺术作为中国中世纪的一部美术史,深入研究其不同文化的相互借鉴和兴衰发展中隐含的艺术规律,对于重构中国传统文化精神,突出中吲当代艺术的民族性、时代性,都具有十分重要的现实意义。  相似文献

Empirically rich and historically illuminating, Gilded Voices contributes a new and important perspective to the growing field of scholarship dedicated to rethinking PRC cultural history beyond the conventional dichotomy of Mao-era state domination and Reform Era autonomy, By corroborating a range of historical source materials-from personal interviews, municipal archives, periodicals, and audiovisual recordings-Qiliang He constructs a convincing argument that market competition and pursuit of individual livelihood played a much larger role in early PRC culture than previously thought, a pattern that, He shows, continues in the Reform Era, rather than emerging after the Cultural Revolution as something new.  相似文献

Abstract: This paper discusses the productive role of storytelling in community struggles for environmental justice. The individual and collective task of environmental justice storytelling highlights where the politics of pollution intersect with geographical imaginations. Storytelling takes on a productive role in transforming localized and individual emotions and experiences of environmental injustice into public knowledge that is performed in the world. This paper draws on a case study of nuclear waste disposal at Yucca Mountain in Nevada. I focus on how storytelling enacts scenarios of environmental witnessing and transformation that hold together a plurality of presences, absences, action and imagination, past histories and hope for the future.  相似文献

Poverty is often thought of as an inevitable social condition, and the blame for any shortcomings in governmental welfare policies is frequently placed upon the failings of individuals, markets, and demography. By exploring the influence of neoliberal politics on archaeologies of slum-life this article makes the case that less emphasis should be placed upon the perceived failings of individuals and more effort should be placed on recovering the complex social networks which sustained community-life within Hungate and other so-called urban slums.  相似文献

Level IV of Molodova I, an open-air Middle Paleolithic site in the Ukraine has been described by some researchers as a possible source of evidence for early symbolic behavior. We examined bone objects from this layer that were identified by Ukrainian researchers as exhibiting possible Neandertal produced engravings including two anthropomorphic figures. While we have determined that there is no evidence of symbolic activity at Molodova I, the database we have created, with its systematic recording of traces left by taphonomic agents on faunal remains, provides a better understanding of the overall site taphonomy.  相似文献

Recently the value of Marxian approaches to human geography has again been called into question in the pages of Antipode. In this paper I review the reasons as to why geographers re‐discovered Marx and then, from the late 1960s, began to engage with Marxian approaches. I then consider some of the reasons why Marxian approaches in their turn became the subject of critique in geography and some of the alternatives explored in the wake of this. The conclusion is that a pluri‐theoretical human geography is necessary but that Marxian approaches remain of central significance to radical and critically minded geographers.  相似文献
