The physical spaces of imperial education during the Qing were carefully constructed sites of political architecture that sought to shape the behavior of princes, emperors, and their teachers while projecting dynamic images of power. This article examines a range of buildings associated with the Qing pedagogical apparatus. It argues that the changing spaces of imperial education drew on both classical ideals and international iconographies of power to create and disseminate a fluid vision of rule. In the eighteenth century, the Qianlong emperor ordered the construction of the Biyong Hall at the center of the Imperial Academy in Beijing for exclusive use by the emperor during the Imperial Lecture, combining classical Han Chinese and Manchu expressions of authority. Throughout the nineteenth century, heirs to the throne and young emperors were trained in classrooms filled with calligraphy penned by their ancestors. Aphorisms drawing on the Confucian classics, as well as Daoist and Buddhist texts, urged the young rulers to strive for dynastic renewal. Finally, at the start of the twentieth century as the Qing worked to transition to a constitutional monarchy, imperial classrooms around Beijing were infused with Western architectural styles, incorporating new strands of authority for the reforming Qing dynasty. 相似文献
Although the close association of word and image in medieval cartography is widely acknowledged, the significance of the relationship after the rediscovery of Ptolemy's Geography and throughout the Renaissance has been overlooked, despite Abraham Ortelius's choice of the term ‘Reader’ for users of the Theatrum orbis terrarum (1570). In this paper, the map of the world, which (as in Ptolemy's Geography) opens Ortelius's Theatrum, is analysed to show how Ortelius's concept of space was very different from Ptolemy's. Attention is drawn to the content of the texts on the map, to Ortelius's notion of geography as the eye of history, and to the importance in the Renaissance of the emblem as a conceit, or device, in the system of acquisition and transmission of knowledge. As in emblems, the words on Ortelius's map are not there to explain or to comment on what is seen but to give the image meaning; the purpose of the map is to invite contemplation of God's world. The map is contradictory, however; for Ortelius's accurate and up‐to‐date presentation of the physical world is qualified by a verbal statement that the world is ‘nothing’, a mere pinpoint in the immensity of the universe. It is concluded that Ortelius was not a geographer in the same way Ptolemy was, and that Ortelius was using geography as a philosopher and his world map as an illustration of his moral and religious thinking. 相似文献
Timber structures can be degraded during their life both by structural problems and by biological degradation factors like fungi and insects. The occurrence of those biodegradation agents could lead to a loss of their structural integrity, in the absence of appropriate maintenance. An early assessment of the decay is even more important when the wooden structures are part of historical buildings, in the interest of conservation of cultural heritage.
This article presents an application of microwave reflectometry for the in situ evaluation of timber structures. The measurement system allows detecting anomalies inside the material in a non-destructive and non-invasive manner.
The reflection coefficient is measured by means of a vector network analyzer (VNA) using a double-ridge antenna which transmits the continuous-wave (CW) microwave signal and receives the signal reflected by the material under investigation.
Measurements on laboratory models demonstrated the feasibility of the method. Results obtained on timber beam sections, compared with the findings of traditional investigation methodologies, demonstrate the potentiality of microwave reflectometry, suggesting its possible usefulness during the diagnostic phase as a non-invasive tool for preliminary screening. 相似文献
This paper examines the rural ethnic heritage-inspired transformation of the built environment of a relatively small county town in China. The paper explores the ways village-based ethnic heritage is being repositioned by local leaders as a resource for tourism-oriented revenue generation and for ‘improving’ the ‘quality’ and behaviour of town residents. Viewing heritage as a ‘technology of government,’ the paper provides an analysis based on three interrelated themes: the discourses by which town leaders and planners have conceived the heritage development project as one of improvement, the spatial practices by which those discourses have been realised in the built environment, and the ways residents themselves have appropriated and ‘inhabited’ this new ‘villagized’ city as they go about their everyday urban lives. Based on ethnographic field work, a survey, and extended interviews over a period of four years, the paper finds the town leadership’s faith in the ability of the built environment to shape and improve the conduct of citizens to be overstated. While the town’s transformation has generated a new sense of urban modernity among residents, their ways of inhabiting and using urban space have little relevance to the ‘heritagized’ environment in which they now live. 相似文献
This article focuses on a community located in downtown Rio de Janeiro that was destroyed to make way for the commemorations of Brazil’s Centenary of Independence in 1922. Morro do Castelo was once a space customarily inhabited by Afro-descendants, but Italian and Portuguese immigrants predominated there by the time of its destruction. I argue that whatever Castelo’s racial heterogeneity it was imagined and treated as a black space by planners and policy makers, hence its disposability. In Castelo's neglect during the colonial period and in the urbanization projects that sought to destroy it in the first two decades of the 20th century, one can discern the continuity of imperial processes of ruination of racialized spaces and bodies. The article examines ways in which residents of Morro do Castelo established territory and engaged in various forms of refusal when faced with the ruination of their neighborhood. The spatial practices of the hillside’s diverse population suggest that its various racialized and ethnic groups mapped difference onto a palimpsestic site that defied official classificatory systems and troubled official mappings of the concept city. 相似文献
This article introduces the concept of urban togetherness to parade research. We suggest that some parades are practices that establish urban relations and not community, carnival or consumerist relations. We develop this new perspective on the basis of a literature review and an analysis of a parade in Brussels, the Zinneke Parade. In the literature review, we distinguish between three existing perspectives on parades. Research has argued that parades serve to build community and claim identity, to suspend social positions and to enable tourist/consumerist relations. In our analysis, we focus on concrete features of the Zinneke Parade obtained through video recording showing the costumes and objects carried along, the rhythm and sounds, and the borders and interactions established during the parade. We argue that the Zinneke Parade should be understood as a form of urban togetherness in which participants and spectators are exposed to each other in a practice that does not necessarily lead to identification and shared meaning. 相似文献
