萨珊波斯帝国在拜占廷金币传入过程中的影响

地处东西两大文明交汇点的萨珊波斯帝国,不仅本身创造出灿烂辉煌的文明,也为东西商贸文化交流做出了巨大的贡献。本文以中国出现之拜占廷金币及其仿制品为线索,考察萨珊波斯帝国在罗马帝国（及拜占廷帝国）与东方之间的联系作用,证明它在拜占廷金币向东传播、流向中国的过程中有着非常重要的影响,是古代东西经济文化交流的重要媒介之一。     

中美首次高级会晤中的交流与交锋——来自中国、美国外交档案的研究

1971年7月9～11日,美国国家安全事务助理亨利·基辛格秘密访华,同周恩来总理会谈。这是中美两国政府交往中断了20年后的第一次重要高级会晤。这次会晤有两个目的:一是商讨尼克松访华的时间、主题、性质和可能的结果等问题;二是就双方关心的亚洲和世界和平问题进行讨论,为尼克松访华成功奠定基础。具体而言,会晤商谈的问题包括七个方面:台湾、印度支那、与苏联和日本等其他大国的关系、南亚次大陆、建立中美安全的沟通渠道、军控和尼克松访华公告。会谈为中美关系实现正常化迈出了关键的第一步。     

Eco-cultural niches of the Badegoulian: Unraveling links between cultural adaptation and ecology during the Last Glacial Maximum in France

This study details an application of eco-cultural niche modeling (ECNM) using two modeling architectures—a genetic algorithm (GARP) and maximum entropy (Maxent)—aimed at examining the ecological context of sites with archaeological remains attributed to the culture termed the Badegoulian (ca. 22–20 k cal BP), which dates to the middle part of the Last Glacial Maximum (ca. 23–19 k cal BP). We reconstructed the ecological niche of the Badegoulian and assessed whether eco-cultural niche variability existed within this technocomplex. We identified two broad but distinct spatial entities in the distribution of Badegoulian sites based on lithic raw material sources and circulation, and found that these spatial units share a similar ecological niche. We discuss the implications of territorial differentiation within this niche in light of research on land use by culturally affiliated groups within a broad cultural entity. We propose that Badegoulian circulation networks reflect distinct social territories associated with particular conditions within a single ecological niche. This study illustrates the utility of combining ecological niche reconstructions with archaeological data to identify and evaluate diachronic trends in cultural continuity for situations where such patterns may be missed when the focus of study is restricted solely to lithic technology and typology.
