2012年7月至9月,为探索麦类作物和外来畜养动物的传播途径,青海省文物考古研究所对位于青海互助土族自治县加定镇加塘村的金禅口遗址进行了考古发掘。共揭露齐家文化时期房址5座、灰坑15个、墓葬1座和陶窑2座,出土陶器、石器、骨器、铜器、木器等200多件及大量动、植物遗存。本文对其中的典型遗存进行了详细介绍。通过与邻近地区的同类文化遗存进行比照,本遗址出土的齐家文化典型器型与其存在许多相似之处。选取炭化植物种子10个样品,小麦、大麦、粟和黍,经北京大学考古文博学院碳十四实验室进行测年,数据结果的年代范围在2200~1750BC。综合考虑基本上反映了金禅口遗址齐家文化聚落的绝对年代。遗址中出土的众多细石器和大量动物骨骼反映了发达的畜牧业和狩猎经济。而通过对遗址中采集的土样轻浮物进行鉴定,显示碳化农作物种子10163粒,占出土碳化植物种子总数的90.4%,表明采集业是当时经济生活的重要补充,但农业仍是主要的生计方式。由此可见,金禅口遗址所处的自然环境决定了齐家文化时期先民的生业模式复杂多样。  相似文献

Migration theories often ignore the role that states play in stimulating migration through public assistance policies. Using the case of Mexico, this article explores the role of the state as a migrant‐producing actor by examining the relationship between migration and social assistance policies in the form of monetary cash transfers. It argues that direct, unconditional cash transfers, like those provided by agricultural programs such as Procampo, rather than providing the incentives needed to retain individuals in their home country, may instead be providing the resources needed to migrate, particularly if the amount of the transfer is insufficient to spur investment. Instead of discouraging migration by enhancing economic opportunities and reducing poverty, such policies can actually make it easier and more appealing for its beneficiaries to migrate.  相似文献

Two Taiwan-based economists estimate the technology content of exports by the machinebuilding industry of the East Asia region during 2004-2008, using comparative analysis to clarify changes in the relative competitiveness of four East Asian nations (China, Japan, South Korea, and Taiwan) accompanying the formation of a regional trading bloc and production networks. In particular, they examine the technology content of these countries' machinebuilding sub-industries' exports within the Southeast Asian market (documenting the rise of the machinebuilding industry in China) as well as the penetration of Japanese, South Korean, and Taiwanese sub-industries into China's market. The results point to areas of emerging competition among China, South Korea, Japan, and Taiwan for East Asian markets, which can only be expected to intensify in the future.

瑞典隆德大学(Lund University)图书馆收藏的一套50幅的中国瓷器烧造图,是18世纪上半期绘制于广州的早期外销画作品,由瑞典东印度公司首任大班坎贝尔从广州购回,是目前所知的数量最多的一套瓷器烧造图。这套广州外销画的早期图册,为我们了解早期外销画的发展、早期中瑞贸易史、瑞典早期远东科学考察史以及中国瓷器生产史,提供了非常珍贵的图像资料,其历史价值和文化价值值得肯定。  相似文献

Trace element compositions of 25 shards of Chinese Late Ming export blue-and-white porcelain from Zhangzhou and Jingdezhen kilns are analysed by Inductively Coupled Plasma Mass Spectrometry. Principle components analysis and REE distribution curves are used to establish method for provenance unknown Chinese export blue-and-white porcelain which may have originated from Zhangzhou or Jingdezhen kilns. By matching the REE distribution curves of Zhangzhou kiln samples and parent rocks of the possible clay sources used to make Zhangzhou blue-and-white, and comparing it with previous results of geological, geochemical and archaeological researches, the clay used for producing Zhangzhou export blue-and-white has been identified as having been collected from the weathered shells of a nearby potassium feldspar miarolitic granite outcrop.  相似文献

Despite decades of efforts to curb the global supply of illicit drugs and significant shifts in how those efforts are designed and implemented, illicit crop cultivation persists. In this paper, we examine state and international development efforts to eradicate coca in Peru, opium poppies in Laos, and cannabis in California, USA and the ever-changing discourses used to justify and design these interventions. Scholarship in political geography frames eradication interventions as serving ongoing efforts to extend state and market power into the regions in which illicit crops are grown and to marginalize the people growing them. We find that environmental discourses are increasingly used to assert the need for continued illicit crop interventions, and that these discourses articulate with historical and ongoing portrayals of smallholders as environmentally destructive. Environmental harm narratives that justify enforcement and eradication efforts under the guise of protecting ecosystems from illicit crop farmers can become self-fulfilling prophecies when they disproportionately impact smallholders and push them into marginal geographic and economic positions. Our cases illustrate that environmentally-justified interventions drive cycles of marginalization for illicit crop smallholders, often conditioned by race or ethnicity, who are then portrayed as environmental criminals. Meanwhile, new state-sanctioned spaces of opportunity and profit are created for more powerful actors who are able to capitalize on the removal of illicit crop growers from the land.  相似文献

This article examines the economic and political impact of the Second World War upon a small outpost of Britain’s informal empire. It analyses the multiple ways in which the economy, trade and governance of the Trucial Coast were disrupted, disturbed and challenged by the exceptional circumstances of the war. In response to these circumstances, a variety of emergency arrangements were introduced, resulting in an unprecedented degree of involvement of outsiders and foreign agencies in the management of the local economy. The transformation of Britain’s traditional policy of non-interference in the internal affairs of the Trucial Coast is traced back to the exigencies of wartime conditions.  相似文献

ABSTRACT

This paper argues that even when India had posited its peaceful nuclear explosion (PNE) of May 1974 as a mark of resistance against a prejudiced nuclear order based upon the NPT, India's policies in the post-PNE period confirmed with many aspects of the emerging non-proliferation consensus. India's response was guided by two major factors. On one hand, were its long-held principles such as the right to peaceful uses of nuclear energy (including PNE's) and the right to nuclear technology cooperation for peaceful purposes. On the other hand, were the pragmatic policy choices it had to make as advanced nuclear states worked towards a stricter non-proliferation regime. In this struggle between India's principles and its necessities, India's nuclear behavior was guided much more by pragmatism rather than by its normative preferences. Yet, even when India made major compromises on its nuclear principles in private, in public India stuck to the rhetoric of its principled opposition to the NPT regime. These tensions between India's actual practice and its public policy are evident on three major non-proliferation issues: nuclear safeguards, export controls and the danger of nuclear proliferation in its neighborhood.  相似文献

雍正皇帝为稳定商品市场的银钱比价,对铜钱制度深刻反思后进行了全面改革,至乾隆时期,改革后的铸钱成本长期保持在铜钱千文含银一两以下, 成本较低。而同一时期商品货币流通领域铜钱对纹银的兑换却低于一两,钱价高昂,钱价与钱值相悖。形成这个问题的根本原因,在于清政府对铜斤实行垄断经营、压低价格。基于清政府对鼓铸用锎垄断价格而形成的铸钱成本,并不能真正体现钱文的价值含量。铸钱成本的高低应取决于商品市场铜铅价格的高低。乾隆时期钱价高昂,正是当时商品市场铜价昂贵的曲折反映。  相似文献
