This paper expands the Narrative Policy Framework (NPF) by employing an exploratory case study approach to examine the construction of narratives temporally. A large-N Twitter dataset concerning the Bears Ears and Grand Staircase-Escalante monuments controversy is utilized to examine the question: how does the use of narrative strategies change over time? Through the application of change-point analysis, we determine time points of significant shifts towards use of the devil-angel shift, scope of the conflict, and causal mechanism strategies. Overall, we find that organizations do not vary their use of narrative strategies over the course of a policy conflict but instead demonstrate discrete changes in response to certain policy events. Based on our findings, we conclude with suggestions for refining and expanding NPF hypotheses. Specifically, we recommend a more contextual analysis of shifts in narrative strategy use in response to specific events over time.  相似文献

针对深圳博物馆收藏两件明代加彩木雕坐像存在的虫蛀、糟朽、彩绘脱落、开裂、残损等病害,急需进行保护处理的情况。本工作在前期调研和分析检测的基础上,即分别采集了木雕坐像的胎木、加彩层、污染物等样品,利用红外光谱、拉曼、扫描电镜等分析方法对其材质组成、制作工艺及病害进行了综合分析基础上,建立了坐像保护处理工艺步骤:原始档案建立、表面清理、菌虫防治处理、木质朽蚀部位和彩绘层渗透加固、破损及残缺部位修复补全、建立保护修复档案等。选择Primal SF-016作为两件木雕坐像的渗透加固材料,选择无水乙醇作为溶剂,采用较低浓度多次渗透的方法,保证了最佳的加固和防腐防虫效果;修补材料选择聚醋酸乙烯乳液和锯木屑调和补配。处理后的木雕文物器形完整,形态稳定,色泽协调,达到了理想的保护效果。这是对传世彩绘木质文物保护技术的有益探索,对日后同类文物的加固处理有借鉴意义。  相似文献

为了鉴别文物表面常见的天然有机物,采用显微共聚焦拉曼光谱技术采集了古代常用的蛋白类、多糖类、脂肪酸类、树脂类4类6种有代表性的天然有机物的拉曼光谱。通过对皮胶、桃胶、蜂蜡、棕榈蜡、达玛树脂和琥珀标准样品的拉曼光谱分析,发现蛋白类的特征振动峰位于1657cm-1、1305~1252cm-1、1033cm-1及1003cm-1附近;多糖类的特征振动峰位于1463cm-1、1328cm-1、1258cm-1、1088cm-1、977cm-1等;蜡类的特征振动峰位于1470~1350cm-1区间,1659cm-1、1303cm-1、1636 cm-1及1610cm-1;树脂类的特征振动峰位于1660~1650cm-1区间和1460~1440cm-1区间。在对6种天然有机物光谱特征分析的基础上,得出了使用拉曼光谱法可实现古代文物表面常见天然有机物种类鉴别的结论。  相似文献

In the early 1970s, the economic consequences of European Community (EC) policies forced the Council for Mutual Economic Assistance (CMEA) to devise its trade policy vis-à-vis the outside world. With the implementation of its Common Commercial Policy, the EC was about to change the rules and conduct of its foreign trade. The East–West trade boom that took off in the 1960s had created significant commercial links, and substantial dependencies, across the Iron Curtain. The smaller members of the CMEA began to advocate an opening up towards the EC due to their fears of worsening trade prospects caused by the new EC policies. After reconsideration of its allies' commercial needs, the Soviet leadership was pressured to change its mind in favour of a common approach vis-à-vis the EC. This article follows the debate within the CMEA Executive Committee on the socialist countries' dependency on the Western market and on the advisability of opening up to the global market. It relies on official CMEA documents as well as Soviet and German Democratic Republic (GDR) policy-making documents. This article analyses the process of socialist integration in connection with the simultaneous developments taking place in their Western European counterparts, and thereby fills a gap in the historiography of Europe in the Cold War.  相似文献

文物政策科学研究,又称文物软科学研究,是为促进文物事业宏观管理和决策的专业化、科学化和民生化提供支持、咨询、评价和反馈的综合性研究。文物事业是保护和管理国家不可再生宝贵文物资源的特殊文化行业,其政策研究具有特殊性和重大现实意义。但目前文物政策研究成果分散、水平不高,缺乏研究机构和组织规划。  相似文献

This article examines the creation of Gunung Leuser Wildlife Reserve in the highlands of Aceh, Indonesia within the context of the Dutch-Aceh War in the early twentieth century, arguing that conservation was used as a form of counter-insurgency. While the agendas of the colonial military and conservationists diverged at times, they overlapped in their goals to secure Leuser from resident communities, whom they viewed as a threat to colonial order and the ecologies of the region. This article draws together the discourses of militarized conservation with their material implications. It does so by examining the nexus of military and conservation discourses, the historical context of park creation, and the processes by which colonial actors stole rights to land and created new laws and regulations dictating the people's relationships with and access to land. Scholars have shown that conservation discourses continue to normalize human rights abuses, Indigenous dispossession and displacement, and deadly violence against local peoples. These discursive tactics frame expertise and responsibility as residing in the hands of white elites who are tasked with saving imperiled environments from the people who depend on them for subsistence. I suggest that the military and conservation agendas were both operating within overlapping, constructed frameworks of crisis and emergency that constituted the resident communities as anti-environmental subjects. Discourses of environmental crisis in Leuser held a power that justified militarization while concealing the violence from international constituencies at a historical moment when an ideology of Western responsibility for threatened species around the world was growing. Moreover, the history of Leuser as viewed through the analytical framework of militarized conservation helps us rethink the history of Aceh. Through this framework, it becomes evident that the Dutch-Aceh War did not end in 1913, as many historians suggest, but instead continued throughout the colonial period.  相似文献

As the number of conservation areas within England continues to rise, it is increasingly important that adequate care and attention be given to their management. If not, the concept will be devalued and initiatives to protect and enhance such areas will not receive sufficient consideration. Conservation Area character appraisals have recently been suggested as a basis for the management of activities within Conservation Areas. This article considers the nature of advice on appraisals, and then the progress of English authorities in undertaking them. It will conclude with a number of issues and concerns which must be tackled if the potential of theses management instruments is to be fully realised.  相似文献

Many government and non‐statutory registers utilise point datasets to represent cultural heritage places. An effect of this approach is to emphasise that cultural heritage comprises a series of spatially discrete material remains or ‘sites’, suggesting discrete locations which are somehow disconnected from their broader historical and landscape contexts. We advocate an alternative in which spatial representation of heritage is set within a cultural landscape framework, acknowledging that all parts of the landscape have inter‐connected cultural histories, associations and meanings resulting from long‐term and ongoing human–environmental interactions. Results from a collaborative cultural heritage research project undertaken at Culgoa National Park in Australia demonstrate the advantage of this approach. The mapping products produced by the work comprise an interactive electronic DVD Atlas and hard copy maps. Both focus on meeting the management needs of field‐based park staff.  相似文献
