中国特色社会主义文化纲领的历史发展

从改革开放之初提出"两个文明"建设,到十五大正式提出"经济、政治、文化纲领",再到十六届四中全会发展为"物质文明、政治文明、精神文明、社会文明"四位一体,实质是中国特色社会主义事业总体布局的发展过程,是在这个总体布局中社会主义精神文明建设面临新任务、扮演新角色、承担新使命的过程,是中国特色社会主义文化纲领继往开来、不断丰富发展和完善的过程,反映了中国化马克思主义文化理论一脉相承、与时俱进的理论品质和实践品质。     

Chronotopes of study abroad: the cultural Other,immersion, and compartmentalized space–time

Study abroad offers a specific configuration of encountering cultural Others: in a demarcated “abroad” space in a compartmentalized time period. Informed by Bakhtin's notion of chronotopes, this article investigates narratives of American college students who studied in Paris, France and Bilbao, Spain in June–July 2011 based on an ethnographic fieldwork of their stay. I identify two chronotopes held in tension in their narratives that reflect tenets of the discourse of immersion: of homogeneous space where every minute students spend in the host society is “local” time full of learning, which risks portraying the host society as frozen in the time of the students’ stay; and of heterogeneous space where local space–time and outsider (e.g. American students and tourists) space–time co-exist hierarchically, where students strive to show their engagement with the former. This article calls for encouraging students to examine the effects of these chronotopes on their experiences and for viewing study abroad not as an encounter of two cultures but as diverse students joining in the ongoing production of heterogeneous host society space with a compartmentalized yet expanding notion of time.     

A Land and a People of Extremes – Ireland and the Irish in German Cinema

Irish film history has often been seen as a pragmatic “creative bricolage” that draws almost exclusively on images of Ireland and Irishness that have emanated from the cinema industries of the USA and the United Kingdom. Yet, Ireland has also featured in the film industries of other non-Anglophone countries and the images produced in these contexts also represent an element within the vast and extensive archive of Irish filmic images. This article writes the first chapter in the expansion of Irish film history by examining the depiction of Ireland and Irishness in German film. Ireland and the Irish, not unlike the Anglo-American gaze, are depicted as a people and a land of extremes marked by an intensity of emotion, nationalism, Catholicism and alcohol, while extremes of poverty and wild untameable landscapes also feature prominently.     

文物CT图像伪影校正方法研究

计算机断层成像(CT)技术具有不受工件材质限制、分辨率高等优点,可以在不损坏物体的前提下获取其三维数字化信息,因此在文物数字化领域具有广阔的应用前景和巨大的发展潜力。然而在CT扫描与图像重建过程中存在系统几何参数偏差与射线硬化等问题,会导致扫描图像质量下降、文物数字化模型的精度受限。本研究针对上述问题,提出了基于扫描数据的参数校准以及硬化校正算法,并对两件文物仿制品进行了CT扫描实验。实验结果表明,经过本研究方法处理后,扫描图像质量明显提升,重影和伪影现象得到了有效抑制,重建得到的数字化模型能清晰完整地还原文物形貌。该方法可被广泛应用于文物CT数字化工作中,有利于文物的复制、保护、展示以及文化的交流传播,具有较强的科学意义和社会经济意义。     

西北干旱区瓷器文物补配材料耐久性研究

陶瓷器文物修复后,其补配材料常常因展陈、运输以及人为因素发生老化变黄,导致艺术价值降低,影响文物展示效果。因此,了解补配材料和各种填料混合后的黄化机理至关重要。本工作选取瓷器文物修复行业几款常用胶料——合众AAA标准胶、合众AAA耐黄胶、红星509、Araldite 2020、Hxtal NYL-1,以及几款常用填料——滑石粉、高岭土、钛白粉、紫外吸收剂、玻璃微珠,根据西北干旱的气候特点对其进行干热、紫外、盐雾、冻融试验,使用色度仪、硬度计、扫描电子显微镜、X射线衍射仪等对其进行表征,探讨各种材料老化前后的黄化机理,研究气候环境对补配材料的影响。结果表明:Hxtal NYL-1混合补配材料在各种环境中的抗老化能力均较为出色,红星509混合补配材料在盐雾老化及冻融循环中抗硬度老化的性能较为出色;另外,填料中滑石粉与钛白粉的抗色变能力优异,高岭土的抗硬度老化能力优异。修复师可利用上述研究成果选取合适的修复材料用于补配。本试验将基础研究与科研热点有机结合,兼具探究性、综合性,具有较强的应用价值。
