China’s assertive diplomacy in recent years has ignited intense debates among international relations (IR) scholars. Some argue that China’s assertive behaviour is rooted in its perception of increasing power and capabilities. Others suggest that it is US policies that triggered China’s assertive reactions. Relying on an original survey of China’s IR scholars conducted in Beijing in 2013 and using structural equation modelling, we empirically examine Chinese IR scholars’ attitude towards Chinese power versus the United States, their perceptions of US policy in Asia, and their preference for an assertive Chinese foreign policy. We find that both the power perception and policy reaction arguments make sense in accounting for Chinese IR scholars’ attitude regarding China’s assertive diplomacy. However, our research suggests that a more pessimistic view on Chinese power is more likely to be associated with a preference for an assertive foreign policy. 相似文献

四川大学博物馆馆藏书籍档案数量多、时间久、价值丰富。但历经长时间的保存后,出现了不同程度的病害,亟需科学的保护修复。为此,本次研究首先对该馆线装书的病害情况进行了抽样调查;在不破坏文物的基础上,利用无损或微损分析技术,包括酸度计、光学显微镜、傅里叶变换红外光谱仪、扫描电镜-能谱分析仪等,对样品进行分析研究。调查发现,这些线装书均存在不同程度的虫蛀、霉害、受潮、污染、断裂、脆化等病害。分析研究结果表明,这些馆藏线装书的纸张原料以竹纤维和草纤维为主,亦有添加麻纤维、韧皮纤维以改善其机械性能;CaCO_3的存在能有效减缓纸张的酸化;纸张原料中CaCO_3等碱性物质的缺乏、霉菌的滋生、Fe等金属元素的混入等可能是造成部分纸张酸化的原因。 相似文献

我国考古和文物保护工作中物探技术的应用 总被引:7,自引:0,他引:7
钟世航 《文物保护与考古科学》2004,16(3):58-64
20世纪80年代以来,物探技术在考古和物保护方面应用越来越多,在古墓探查、大型古建筑地下遗存现状探查、重要古建基础状况探查、古遗迹断代等方面,地球物理技术都找到了发挥作用的机会。本通过地球物理技术在云冈石窟、龙门石窟、克孜尔石窟、北京故宫紫禁城、嵩岳寺塔、古泗州城遗址、风阳明中都等的物理探查实例,以及查找古墓、古遗迹断代等方面的工作,介绍了我国在考古和物保护领域应用地球物理技术的进展,并指出了物探在用于考古和保时的特点和展望。 相似文献

本文以企业问卷和访谈相结合的方式调查了兰州中小工业企业技术改进的状况及途径。兰州几乎所有被调查企业的主要生产技术自建立以来得到了改进。当地企业的创新主要为二次创新,且二次创新主要是对次要而非核心技术的创新。技术引进是当地企业技术改进的主要途径,其中引进更先进的设备是当地最有效的技术改进途径。作者认为企业创新方式受其经济实力和相对技术差距的影响,区域应视其经济、科技发展水平等而采取不同的科技政策。 相似文献

Since the arrival of Turkish military forces on the island of Cyprus in 1974, archaeological activity below the water in northern Cyprus has been virtually non‐existent. In August 2008, however, an international team conducted an underwater survey in this disputed region to document and assess the variety of maritime cultural heritage present along part of the coastline. This paper discusses the team's survey methods and goals, the discoveries, ranging in date from the 6th century BC to the 14th century AD, and plans for work in 2009. © 2009 The Author 相似文献

By combining underwater survey with formal and compositional study of ceramics, recent work at Burgaz (south‐west Turkey) reveals a late 6th‐ or 7th‐century assemblage of wine and perhaps other agricultural products carried in LR1 and LR2‐related amphoras. Representing various south‐east Aegean and likely Cilician producers, the mixed cargo aboard this probable shipwreck offers insights into the complex dynamics of seaborne distribution at the end of Antiquity. This brief study also underscores the need for documentation in underwater survey of amphora forms and fabrics, particularly those from a period characterized by intensified and diversified production of supra‐regional ceramic types. 相似文献

The social and political transitions that have come about in Russia since the mid 1980s, in particular the legal recognition of the right to free movement in the Migration Law of 1993/96, have resulted in an increase in labour out‐migration from the country. This increase is, however, not nearly as large as one would expect given the poor economic conditions in Russia. This paper presents the results of two surveys that were carried out to assess the migration intentions of Russian workers, the methods they employ to effectuate these intentions, and the obstacles they encounter. The population sample of the first survey represented the totality of active men and women in Moscow. The second survey was aimed at a specific sector of the Russian population for whom the possibility of labour migration is particularly relevant, i.e. highly qualified specialists. On the basis of the survey results, conclusions are drawn with respect to the potentials of permanent or temporary labour out‐migration from Russia. 相似文献
