峡江地区汉晋南朝花纹砖上的车轮纹饰   总被引:1,自引:0,他引:1  
郑君雷 《江汉考古》2006,1998(3):60-68,94
文章对峡江地区汉晋南朝花纹砖上的车轮纹饰进行全面检讨。首先将车轮纹饰分为若干种类,其后以发掘报告为依据讨论各类车轮花纹砖的年代,最终归纳出峡江地区车轮纹饰的演变线索。文章以为,峡江地区的车轮花纹砖大约出现在新莽至东汉初期,东汉中晚期至东晋最为流行,南朝仍有发现。文章同时分析了各阶段车轮纹饰的时代特征,并且简要讨论了与车轮花纹砖相关的若干问题。  相似文献

论中国古代治边思想的特点、演变和影响   总被引:2,自引:1,他引:1  
古代治边思想大体形成于秦汉,发展和延续至清代,其内涵是动态变化的,经历了从肤浅到成熟的过程,各个时期的治边思想又有其特色。古代治达思想总体上有两个基本的特点:统治对开疆拓土多持相对保守的态度,认为理想的边疆治理是“守在四夷”;从“华夷有别”的治边观出发,在边疆地区施行相对宽松的羁縻统治,同时重视在边疆传播封建化的教化作用。章还以封建统治对边疆民族的治策和对边疆的经济开发为例,阐述了古代治达思想对边疆治策的广泛影响。  相似文献

Despite collaborative governance's popularity, whether collaboration improves policy performance remains uncertain. This study assesses the link between collaborative decision making and licensed environmental management protocols in the Federal Energy Regulatory Commission's (FERC's) process for licensing hydropower facilities in the United States. Using results from a previous study of FERC relicensing (Ulibarri, forthcoming), one high‐, one medium‐, and one low‐collaboration case were selected. Using documents including meeting minutes, public comments, and issued licenses, I assessed collaboration and license outputs, then conducted process tracing to examine whether and how differences in collaboration produced differences in license quality. High collaboration resulted in jointly developed and highly implementable operating regimes designed to improve numerous resources, while low collaboration resulted in operating requirements that ignored environmental concerns raised by stakeholders and lacked implementation provisions. These results support the hypothesis that collaboration can improve environmental outcomes, revealing the pragmatic value of collaboration.

The concept of “advocacy coalitions” is the bedrock of the Advocacy Coalition Framework (ACF), one of the most established and successful approaches for understanding policy processes across the globe. This article revisits and sharpens the conceptual definition of advocacy coalitions. We summarize the lessons from its theoretical emphases under the ACF and specify its five attributes (policy actors, shared beliefs, coordination, resources, and stability). Through this specification, we identify the ideal coalition type and several coalition subtypes. We then clarify and make a distinction between how we think about coalitions as a concept and how we approach coalitions empirically. This article sharpens the lens for describing and explaining coalitions toward better observations, theorizing, and measurements. It ends with next steps for further deepening and broadening knowledge about advocacy coalitions.  相似文献

Summary : The article explores deployment of the Darwinian narrative of the “natural history of humanity” in Russian physical anthropology in the late nineteenth to the early twentieth century. It traces two narratives developed by the leading Russian school of physical anthropology: one narrative advanced a universalist vision of collective scholarly enterprise working toward clarifying the missing links in the a priori accepted developmental evolutionary model. The other constructed a new language that undermined the idea of species/subspecies/races/nations/ as stable, externally bounded, and internally homogeneous units and attempted to rationalize imperial hybridity. The article's main focus is on the latter classificatory narrative, its relational methodology, and the protostructuralist units of comparison that it produced.  相似文献

非均质的砂砾石层是莫高窟壁画的主要墙体,但砂砾石层的非均质性如何在水盐运移过程中发挥作用却还不清楚。为此,通过在108窟西壁面上1 m×1 m和2 m×2 m范围的三维高密度电阻率成像监测,发现在这些区域上,墙体电阻率的空间分布都是非均匀的,低阻值区域在空间位置、大小和形状上都会随时间而变化。这明确说明在构成墙体的非均质砂砾石层内存在着重要的水分饱和与非饱和过程(再分配过程),正是这一不断重复的饱和与非饱和过程促进了墙体内水分的运移和盐分在一些特定区域的聚集。研究成果对全面认识莫高窟墙体内的水盐运移机理,减轻和防治壁画盐害都具有重要意义。  相似文献

以山西省转型期旅游发展为例,选取2005、2011和2017年17项指标构建城市旅游发展综合实力评价体系,基于改进场强模型,借助GIS技术和地理探测器模型,分析旅游场强时空异质性特征及演变机制。结果表明:①旅游场强高值区范围扩大、逐步形成叶脉状网络空间形态,突破了早期“人”形格局限制;②各地市旅游场强前期整体上升,后期集中在大西高铁沿线,城市绝对差异增加,高级别场强类型主要以太原市为中心向边缘扩散演替;③旅游场强空间格局演变具有时序性特征,主导因子经历了二元、三元主导和多元共同作用阶段,对于旅游产业后发省份构建区域旅游场强空间格局具有借鉴和指导意义。  相似文献

This article highlights the renaissance of the essentialist topos of the ‘lazy and irrational’ ‘Südländer’ (Southerner, Southern countries, South) in the German political and media discourses during the ‘Euro crisis’. It argues that it served to legitimate the political and economic measures taken in Southern European countries that pushed them into still more peripheral positions within the European Union (EU) and deepened the cleavage between North and South. Culture, or better culturalism and racism as its political ideological version, thus were used as a trap, as an intellectual battleground for justifying extremely complex economic and political decisions in a simplistic fashion throughout a crucial period of European history. The article furthermore demonstrates how a postcolonial reading may productively decode the processes of Othering taking place within Europe itself, especially between the so-called core and peripheral countries.  相似文献

The article contributes to the smart specialization literature by presenting a new approach, connectivity analysis, where Triple Helix (TH) relations (involving universities, companies and government) are at the centre of the entrepreneurial discovery process. Relations between helices may be seen, from the point of departure of proximity, as preconditions of connectivity, or interaction, measured through expectations and experiences. This offers potential solution to two limitations of proximity approach: its static nature and narrow focus on dyadic relationships. The connectivity analysis reveals the extent of mutual expectations, as well as tensions, or gaps. Based on this analysis, the article presents a policy model that is used to map structures of networks and gaps between TH actors. It may also identify strengths, weaknesses and problems. This analysis is used as input to structured dialogues between actors in leading positions in the TH and in smart specialization policy-making and implementation. This approach may lead to policy interventions supporting entrepreneurial discoveries. The model has been developed in partnership with researchers and the Regional Council of Ostrobothnia. The article also presents this case study and demonstrates the use of the connectivity model in practice.  相似文献

ABSTRACT

This is a personal account of the setting up and first five years of CERN's first institutionalized arts programme, in which artists from different art forms were invited to engage with scientists with no requirements for any outputs. The focus instead was on the creative process, the exchanges between the artists and scientists and their shared knowledge-making. Paradoxically, given this freedom, even by the end of the initial phase of the programme they had produced a range of artworks and performances, some of which were to go on to attract international acclaim. The paper identifies some of the key issues and challenges faced when undertaking an arts programme within a science institution. These issues are rarely openly discussed and written about, yet they are vital for shared cultural learning in this rapidly evolving and increasingly popular field.  相似文献
