马家窑文化包含丰富的不同工艺、纹饰人物形象,本研究在人物形象分类的基础上,首先对马家窑文化人物形象进行了考古学分期、以及人物形象区域分布研究,其后选取东部、中亚地区同时期的人物形象作了对比研究。研究发现:马家窑文化人物形象可分为两期,一期以动物拟人纹与人物形体纹为主,其中,鲵人纹与舞蹈纹是此期特色,器口人面塑中出现了哭泣、惊讶的面部表情。二期出现蛙人纹,大量其他彩绘人物形体消失,继承一期以器口作人面的技法,对面部的五官塑造更加细致,表情更加多样,出现了精致又寓意非凡的裸体人像彩陶壶。马家窑文化人物形象可分为三区,从东往西传播与发展;与东部、中亚同时期人物形象对比,马家窑文化人形象种类和技法更具本地源流,且与其他地区异中有同。本研究为研究马家窑文化的来龙去脉、以及不同文化间相互交流提供参考和依据,对后续分析文化人物形象内涵等均有重要意义。  相似文献

Climate change constitutes one of the most pressing political problems of our time and has profound implications for global justice. However, despite the recent progress of the international negotiations embodied in the Paris Agreement, most scientists and activists agree that the adopted measures are not adequate or ‘just’ considering the magnitude of the problem. Thus, there is a pressing need for political forerunners that could push the regime towards a more just handling of the problem. The European Union for most of the time has presented itself as a strong advocate for progressive climate action and has been called a climate vanguard or ‘green normative power’. This paper critically assesses the EU's role concerning climate change from a perspective of global political justice, which builds on a tripartite theoretical conception, consisting of ‘non-domination’, ‘impartiality’ and ‘mutual recognition’. It inquires to which conceptions of justice the EU's climate strategy and approach to the international negotiations have corresponded, how and why changes have come about, and whether the EU was able to influence the international regime. The paper finds that while the EU started out from a focus on political measures linked to impartiality, after the failed negotiations in Copenhagen in 2009 it has become more open towards policies and instruments in line with mutual recognition and non-domination. Thus, the emphasis moved away from top-down, legally binding measures, towards voluntary bottom-up procedures, a recognition of difference and diplomatic outreach activities. While this shift was necessary to reinstate the EU's influence and secure the Paris Agreement, it could hamper the quest for robust climate abatement measures and global climate justice.  相似文献

四川省馆藏文物保存环境监测区域中心(简称四川区域中心)平台,经过两年多的运行实践,实现了12家博物馆监测站的集成联网。本研究分析了区域中心监测平台运行中常见故障现象的表现形式、故障原因及故障率。结果表明:监测平台的主要故障现象为传输异常和数据异常;除温湿度外的其他监测终端故障率较高;软件平台建设也不够完善,导致数据利用率低,尚不能实现风险评估、预测预警和预防调控等管理功能。针对分析发现的问题,提出一些相应的技术措施和管理措施,为有效降低故障的发生率,提升国内区域中心平台建设提供一定的指导和参考。  相似文献

Turkey’s regional policies are inspired by the new regionalism theory. During past two decades, key concepts of new regionalism, including knowledge economies, specialization, networked cities and innovation, have been incorporated in policy documents. At the same time, Turkey comes from a strong central state tradition that controls local and regional development. At first insight, new regionalism and strong central state control do not fit in the same frame. This research analyses the trajectory of regional policies in Turkey with the aim of explaining how these seemingly incompatible policies can coexist. It argues that regional policies developed at the central state level utilized new regionalism as a part of the strategy to maintain power in the course of transformation of the nation state.  相似文献

We describe the formulation and application of an integrated general regional seismic loss assessment (RSLA) method for buildings in seismic regions. An efficient method for RSLA is valuable for engineers involved in city planning, risk management, and insurance dealings. In contrast to previously reported methods, the framework presented herein is hazard-based and utilizes a regional rapid seismic hazard deaggregation tool that allows regional assessment to be conducted more efficiently. The proposed technique is implemented as an example to assess general regional seismic loss in Los Angeles County for a ground motion hazard with 10% probability of exceedance in 50 years.  相似文献

江西省区域经济发展空间差异研究   总被引:20,自引:0,他引:20  
俞勇军  陆玉麒 《人文地理》2004,19(3):41-45,30
区域差异历来是政府关注的重要问题,也是区域发展理论研究的主要课题。江西省受周边强经济中心的影响,经济区位边缘化趋势明显。近年来江西省突破原来农业大省的发展思路,致力引进发达地区和国外的技术和资金,工业化水平明显提高。目前江西省内部地区差异较1990年明显扩大,而且表现出各地区相对波动较大的特征。本文采用偏离一份额模型,对江西1990-2001年间11年来的发展状况分两个阶段进行分析,探讨江西省区域经济发展差异的空间结构特征,将江西划分为4种发展类型。江西省各地区区位条件的变化是其经济发展空间差异的驱动因素。  相似文献

古代铁器腐蚀产物的结构特征   总被引:4,自引:2,他引:4  
运用X射线衍射、扫描电子显微镜和穆斯堡尔谱分析方法,对河南渑池出土的T_1H_1∶250汉代铁斧表面腐蚀物进行了研究。提出了铁器文物抗腐蚀的原因在于表面氧化膜具有结构上的连续性、改密而不破损。铁器文物最理想的保存环境应该是碱性、干燥无水、无硫、氯等有害元素。  相似文献

Today's domesticated plants not only embody past human–nature interactions, but also reflect social history. Human seed exchange, replacement and loss are important forces in shaping crop diversity. This essay explores regional history in relation to the shaping of maize diversity in the western highlands of Guatemala. This is an area of exceptional maize heterogeneity and a peripheral part of the region where maize was domesticated. Maize diversity seems to have developed through geographic isolation in networks of seed exchange that were generally very local in scope. However, recent studies on Mexican maize suggest otherwise. However, few studies have examined crop diversity or seed exchange from a historical perspective. A closer examination of regional history suggests which processes might be important for shaping the present geographical distribution of maize diversity. Seeds were occasionally transported over longer distances. As a consequence, maize diversity is geographically not characterised by sharp differences between farming communities; the main differences are to be found in regional occurrences. This challenges antimodern ideas of closed, local native ecologies. Consequently, the conservation of maize genetic resources is a challenge, but not entirely contradictory with its transforming socio-economic context.  相似文献

古代西北疆域研究若干问题的思考   总被引:2,自引:1,他引:1  
古代西北疆域是我国疆域的重要组成部分,对古代西北疆域的研究也是边疆史地研究中的重点之一。本文分析了西北疆域研究中应该注意的几个问题,认为以动态的标准确定我国不同时期的历史疆域是研究西北疆域的基本前提;西北疆域地位不断演变,是西北疆域变迁史的基本特点之一,也是西北疆域形成过程的基本形式。同时,文章还就民族、地理环境、国防安全等方面说明了西北疆域形成和发展的内在原因。  相似文献
