木材树种的鉴定是古木结构建筑维修和保护的基础性工作。为配合建水县指林寺大殿修缮保护的需要,为修缮树种选用提供依据,了解木文化的特点。本研究对建水指林寺大殿古建筑主要木构件进行了树种鉴定及对材种配置调查分析。采用切片、显微镜拍照、宏观和微观特征分析等方法,对700个试样进行了树种鉴定。结果表明建水指林寺大殿的木构件共有4个树种,分别是硬木松(Pinus sp.)、白青冈(Cyclobalanopsis sp.)、格木(Erythrophleum sp.)和荷木(Schima sp.)。通过材种配置分析可得指林寺大殿木构件在选材方面达到很高水平,不仅反应了建造年代,而且体现修缮的特性。  相似文献

泉州闽台馆馆藏木质类文物的保护处理   总被引:1,自引:0,他引:1  
福建泉州闽台关系史博物馆多年来收藏的大批木质类文物,不少遭虫蛀和霉菌侵袭。为了不让这些滋生虫菌的文物带到新馆,对这些文物进行了保护处理。先采用溴甲烷常压熏蒸方法杀灭木质文物体内和体表的成虫、虫卵和菌丝。再用软毛刷对木雕文物表面灰尘等物进行小心刷除,然后用水或25%酒精或酒精和丙酮混合液仔细擦拭清洁处理。再用Sparpec 08木材防蛀防腐剂进行渗透处理。保护处理结果表明,本方法技术简单、快捷、易于掌握、实用性强,适用于大批量藏品的杀虫灭菌保护。  相似文献

Recent debates in the history of science aimed at reconstructing the history of scientific diplomacy have privileged the analysis of forms of diplomacy coming from above. Instead, the objective of this paper is to raise awareness of these debates by looking at attempts at scientific diplomacy from below. Such a shift in perspective might allow us to observe the impact of marginalized social agents on the construction of international diplomatic choices. This article particularly focuses attention on how the legacy of Bernalism has fostered the emergence of two different types of science diplomacy. On the one hand, Bernalism has influenced the goals of organizations such as UNESCO and the World Peace Council, which are forms of science diplomacy I would term from above. On the other hand, Bernalism has also been at the origin of radical scientific movements that I propose to interpret as forms of scientific diplomacy from below. These have, in fact, played a cardinal role not only in raising public awareness of the social and political roles of science, but also in the more direct participation of scientists in defining the political objectives of their research activity. From this point of view, I analyze how an association like the World Federation of Scientific Workers proposed (at least in the beginning) greater democratic participation than the top-down structures of other forms of scientific internationalism.  相似文献

This essay will discuss the hegemonic role that texts have come to play in the historiography of subcontinental mathematical traditions. It will argue that texts need to be studied as records of practices of people's working lives, grounded in social hierarchies. We will take particular mathematical texts to show how different occupational registers have come to shape practices that defy the binaries of concrete and abstract, high and low mathematics or the pure and applied conundrum. Measuring, counting and accounting practices as part of the routine work of practitioners performing their caste occupations then provide us with a spectrum of the computational activities that controlled and regulated the lives of people in the past. In the process the act of computing itself gained certain political values such as cunning and manipulation, identified with professions of village accountant and merchant, for example. Drawn from my earlier work on these records, I discuss the occupational role of the accountant as a political functionary who assessed and authenticated the measurements of land and produce in the village, making values of the labor performed by others, and creating avenues for his own proficiency as a mathematical practitioner.  相似文献

The Germans from Russia are a prominent settlement group in the rural landscape of Saskatchewan. Perhaps because they came incrementally, by chain migration, rather than by organized group colonization, they compose an ethnic group little noticed by historians. Also, their immediate origins are divided, inasmuch as earlier German-Russian immigrants came directly from Russia, whereas many twentieth-century German-Russian immigrants came to Canada from the United States, mainly from North Dakota and South Dakota. This article offers the first focused, scholarly historical treatment of German-Russian immigration and life in Saskatchewan. Drawing on oral histories collected with the support of the Faculty Research Program of the Canadian Embassy, it focuses particularly on growing up German-Russian on the prairies, positing a German-Russian ethnic identity distinct both from neighbor immigrant groups in Saskatchewan and from origin communities in the United States.  相似文献

Abstract

Among the colourful characters that populate eighteenth-century military history, the French-born comte de Bonneval (1675–1747) has been kept alive in historical memory longer than most. His surprising conversion to Islam and contribution to Ottoman military reform long made him a popular subject for biography in his own right. Nowadays, he mainly features in biographies of Prince Eugene of Savoy. Both were commanders in the Habsburg army, and for nineteen years they were close companions in war and peace.1 The circumstances that turned Bonneval's friendship with Eugene to enmity also led him in 1729 to offer his services to the Ottoman Empire. For most scholars, this is the moment when his actions became of lasting historical significance. The Ottomans, who suffered in the eighteenth century a series of military defeats, employed foreigners to help them reform their army. After converting to Islam and renaming himself Ahmed Pasha, Bonneval became the first of these when the grand vizier, Topal Osman, invited him in 1731 to reform the Ottoman artillery corps. He moved to Constantinople, added the sobriquet ‘Humbaracl’ (bombardier), and became a noted figure at the court of Sultan Mahmud I. Until Bonneval's death in 1747, Europeans having dealings with the Ottoman regime looked to him for assistance in navigating its internal politics.2  相似文献

外籍人才引进中的国籍之争与“中国话语”的构建   总被引:1,自引:0,他引:1  
论文阐述了国籍政策调整的国际趋势;探讨了现代国籍理论的西方特性、中国国籍政策的特殊内涵等问题;并对当前关于人才引进中国籍争论的几个误区进行了分析。认为中国的单一国籍政策是强化国族认同的内在动力和客观需要;放松国籍限制只是全球化时代的趋势之一,不能忽视强化主权认同、努力消除双重国籍潜在风险的趋势;基于近代西方移民文化的国籍理论有悖于近代中国历史演进规律及国家现代化进程;本族裔外籍人才的个人权益只是国籍政策调整中的一部分依据;通过"双重国籍"形式主要是解决公共服务与发展机会两个方面的问题,而这完全可以通过其他形式或途径进行解决。  相似文献

Abstract

Widespread moral corruption, particularly of the sort fostered by their internal security agencies, was a key feature of communist regimes. The Lives of Others provides a dramatic portrayal of this phenomenon as it occurred in East Germany. The film can appear, given its central story of the moral redemption of a Stasi officer through his becoming intrigued by the lives of artists, to be an overly idealistic or audience-pleasing testament to the humanizing power of art. But the film also reveals the possible moral corruption of the artists. This essay provides a typology of the sorts of moral corruption exemplified by the situations of different characters in the film and shows that the main artist is actually saved from his impending corruption by the Stasi officer's actions. This reciprocal rescue is the key feature of the film's plot; it teaches that while art can undermine and resist totalitarian corruption, it is also susceptible to its snares—especially when it apolitically relies upon its own resources.  相似文献

Recent revelations of corruption in Italy have encouraged speculation about its social foundations. This article addresses the specific issue of the relations between patronage and corruption, drawing attention to their common basis in control over the circulation of information. Examination of patronage from this perspective suggests some weaknesses in the conventional accounts of its distribution, organization and consequences. Since bureaucracies are the principal modern agencies for the collection and storage of information, changes in the relations between and within bureaucracies, political and administrative, can be expected to provoke changes in the structure and stability of patronage networks. That dynamic of patronage, shifting its basis from status to contract, is illustrated in the context of Italian politics in the 1980s.  相似文献
