高校玻璃艺术的实训教学研究

自2000年以来,北京、上海、广州等地的高校建立了玻璃工作室.国内繁荣的玻璃工业环境,为专业发展带来美好前景,更多的高校加快了开设玻璃艺术课程的步伐.本文结合广东高校玻璃工作室建设实践,对实训室必要的安全防护措施展开研究.为玻璃艺术课程的实训安全、科学进行提供参考思路.     

Environmental Melodrama

Rhetorical scholarship criticizes melodrama for its tendency to simplify and reify public controversies and valorizes the comic frame as an ethically superior mode of rhetoric. These judgments are rooted in the discipline's reliance on Burkean categories, a reductionist conception of melodrama, and an implicit assumption that social unification should be the telos of rhetoric. In response, this essay advances a concept of melodrama as an integrated set of rhetorical appeals. It uses examples of environmental rhetoric to illustrate how the inventional resources of melodrama can transform public controversies and oppose dominant discourses that rationalize or obscure threats to the quality and existence of life on Earth. Based on these arguments, the essay endorses a sophistic critical perspective that foregrounds timeliness as the primary ground for rhetorical judgment and refuses to treat any rhetorical frame as inherently superior to another.     

Material analysis of the wall paintings in Xialu Temple,Tibet Autonomous Region,China

This wall paintings technology study in Xialu Temple was carried out by in situ investigations and laboratory analysis. The techniques used to analyze pigments, ground/white preparations, and binding media were: optical microscopy carried out with visible reflected light and ultraviolet light; polarized light microscopy; micro-Raman spectroscopy; micro-Fourier transform infrared spectroscopy; and scanning electron microscopy. The characterization of pigments, including the discovery of two rare organic pigments, improves knowledge about traditional Tibetan paintings. The analysis of the binding media and different types of ground/white preparations (asbestos, kaolin, and illite) allowed us to identify different stratigraphic compositions. Our findings indicate that the study areas were painted during at least four different time periods.
