20世纪初,中国古物大量流散欧美,价格高、易携带的古玉尤为大宗。笔者于1979年-1980年曾旅行探访20余所博物馆,在各馆库房仔细研究玉器。到1990年代,再多次前往重要的馆藏从事专题研究。"良渚玉器上的刻画符号"就是当时我密切关注的专题之一。在本篇中,笔者除回顾百余年流散欧美的良渚古玉收藏及出版情况,介绍四件圆周有刻符的良渚玉璧外,也略论约16至20世纪仿赝良渚古玉的特征。  相似文献

Contrary to recurrent statements that neoliberalism was implemented from the late 1970s in the United Kingdom and United States, this article shows how in fact, this political ideology was rolled out in Western Europe much earlier, in the years following World War II. The experiences of Italy, West Germany and France reveal how some neoliberal reformers took advantage of postwar geopolitical crises to impulse a new spatial regime of sovereignty based on macroregional economic integration and submission of domestic policies to international economic competition. Far from being hegemonic, this neoliberal opening up of state spaces is implemented within the framework of a composite, flexible and ever evolving policy regime. A multifactorial and complex explanatory framework is used to show how neoliberalization in Western Europe takes the shape of a systemic process of macro-regional economic integration.  相似文献

The eagle owl (Bubo bubo) is the main leporid predator among nocturnal raptors. Although its role as an accumulator of leporid remains in archaeological sites has already been demonstrated, the taphonomic signature of this predator has not been properly characterised. Here we present the analysis of two samples of modern leporid remains recovered from eagle owls' nests with the aim of contributing new data to this subject. Results show that although variability occurs, the observed anatomical representation, breakage and digestion patterns allow us to distinguish this raptor from other rabbit predators. Finally, several characteristic features are noted to distinguish eagle owls as agents of leporid bone accumulations in the fossil record. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

This article argues that during the 1970s, the United States Department of State and other US officials sought to promote and maintain Afghan political neutrality as a means of Soviet containment in Central Asia. This piece follows the evolution of this diplomatic model through the 1970s, how it interacted with various Afghan regimes and ultimately became an impediment on the imagination of US officials in predicting the Soviet invasion of Afghanistan.  相似文献

ABSTRACT

Climate niches that modern humans and earlier hominin ancestors occupied have changed dramatically over time, but the extent of those changes has gone largely undocumented. This study investigates the manner in which the realised hominin climate niche has expanded, contracted, or stayed stationary across four time periods (Last Interglacial, Last Glacial Maximum, Mid-Holocene, and 1950–2000) in Western Eurasia. Using spatially gridded general circulation model data and site locations this study examines climate variables from archaeological sites and current Western Eurasian cities to describe both the regional Western Eurasian fundamental and realised climate niches. Changes between the three prehistoric periods and modern-day time period are analysed by calculating each realised niche breadth, overlap, position, and variance. Results indicate that as global temperatures cooled from the Last Interglacial to Last Glacial Maximum, populations expanded their climate niche breadth beyond that of earlier Neanderthal groups, shifting toward regions with less seasonal variation. Conversely, Mid-Holocene humans, who saw the proliferation of both agriculture and population, contracted their realised climate niche space. The contraction and expansion of realised climate niche space illustrates how hominins have evolved the capacity to shift their niche through changes to their subsistence strategy and adaptations to overall climatic conditions.  相似文献

护羌校尉是始置于西汉时期,专门管理羌人事务的重要官职。然史学界对它的始置年代、名称、执掌等问题均有不同的看法。本文主要以近出的悬泉汉简为主,结合传世文献考证后认为,护羌校尉的设置有一个发展变化的过程,其前身就是汉朝政府临时性派出的使者,汉武帝神爵二年(前60)后成为一个固定的官职。其职责是管理活动于凉州刺史部内各郡县的羌人,同时对塞外羌人负有侦视之责。护羌校尉持节巡行各地,又被称为护羌使者。  相似文献
