Deterioration of Yungang Grottoes: Diagnosis and research

Yungang Grottoes, in Datong City of Shanxi Province, China, as the state-level key cultural relic preservation organ, have been subjected to severe degradation due to natural and human factors over the years. Since January 2010, site investigation and research on Yungang Grottoes, assisted by the Xi’an Relics Protection Center and Yungang Grottoes Cultural Research Institute, have been carried out in the laboratory of cultural relics conservation materials in Zhejiang University. Our investigation of the deterioration characteristics of these grottoes is presented here. The paper describes about 12 types of diseases in detail represented by dust deposit, salt crystallization and black crust. Relevant samples have been collected and analyzed by means of SEM, FT-IR, XRD and EDAX to study the potential hazard to the sandstones and conservation methods, which could be used to help guide remediation efforts directed at reducing the weathering problem.

Fear as political dynamics: Chinese peasant workers’ struggle over social security

This article attempts to understand the subject formation of Chinese peasant workers by exploring the emotional dynamics of their struggle for social security, in particular, the new political possibilities created by emotional forces, and the complex ways they experience and articulate the distinctive kind of emotional politics that binds peasant workers with the state in their co-production of emotionally charged power relations, identities, and subjectivities. It formulates an analytical framework that explores the emotional politics of fear that plays out in the context of economic restructuring. In contemporary China, the conflict triggered by social insurance contributions has become a component of the ensuing social crisis, where many protest events are triggered by widespread outrage at the violation of legal rights to social insurance and other welfare security. This research focuses on the struggle of a group of peasant workers at a UNIQLO supplier in Shenzhen, exploring how their fears for the future are constituted, and how their emotional feelings of insecurity motivate collective action and reconfigure their emotional identity and subjectivity in the face of extreme risk. Informed by a relational understanding of emotions, this paper investigates the complex ways in which the proliferation of fear, as a result of an anticipated pain in the future, articulates the process of subject-making in the face of increasing instability and precarity. The study attempts to demonstrate the centrality of fear for China’s sociopolitical order and the radical action of labor resistance.

甘肃省业余羽毛球运动员后场正手击高远球的运动学分析

运用文献资料法、三维影像分析测试和图像分析法、数理统计和综合分析法,对甘肃省业余优秀羽毛球运动员后场正手击高远球技术的参数进行分析.结果显示:甘肃省业余羽毛球运动员的肌肉质量和力量在竞技对抗能力上处于劣势.通过相关性检验,发现准备阶段、引拍阶段是影响甘肃省业余羽毛球运动员整体技术的关键阶段.准备阶段肘关节角度直接影响挥拍阶段顶肘、吊拍的动作衔接;引拍阶段躯干扭转角度小影响腰腹背肌肌力的储备量;挥拍击球阶段动作基本符合“鞭打”的原理;随前阶动作还原速率过慢,影响下一次动作的准备.因此建议甘肃省业余优秀羽毛球运动员应注重专项力量和身体灵活性的训练,来弥补先天身体形态上的不足;应依据身体形态的指标选拔优秀苗子,把培养甘肃省青少年羽毛球后备力量作为一个长期阶段性的目标;以专业运动员技术动作的关节角度为标准,学习、纠正和完善自身动作,保证技术动作的合理掌握和运用,从而有效提高甘肃省各年龄段业余羽毛球运动的整体水平.

中国语言——从僵化的发展到全新的、充满活力的名

2006年7月,由于查找资料的需要,译者在上海徐家汇藏书楼翻阅《字林西报》,无意中在1924年7月14日《字林西报》60周年增刊上发现了胡适的这篇文章。这份增刊可以说是一份当时中国各界名人的文章荟萃集,除了胡适,还有诸如唐绍仪、宋美龄等人的文章,每位都在其擅长的领域发表了自己的看法。胡适最重要的成就之一便是提倡和推广白话文,鼓吹新文学。此篇文章的主旨便是推广白话文运动。全文大致介绍了中国的白话文运动和文学革命,并得出文言文已死,而白话文则适用于从文学创作到社会生活的各个方面这一结论。这也是胡适的一贯观点,在他的《历史的文学观念论》、《建设的文学革命论》、《文学改良刍议》等文中,以及《国语文法概论》、《白话文学史》等著作中,他一再强调白话文取代文言文乃历史之大势。胡适认为,过去的文学已经僵化,并且有三大毛病,即无病呻吟、摹仿古人和言之无物,而新文学正是要改变这些毛病。新文学的本质是"活的文学",认为文学语言要"活",需用浅显生动的白话进行创作;文学精神要"活",需有真情感和真思想的贯注,而具有这种文学性的文学在胡适眼中就是白话文学[参见刘波.胡适论"活的文学"--民间文学之文学性探析[J].四川师范大学学报(社会科学版),2007,(2).]。这次发现的这篇文章除了概括了上述观点外,还由于是刊登在英文报刊,是供在沪外侨及海外人士阅读的,胡适在文章中描绘了一个白话文运动的全景,从文言文兴盛的原因到需要改革的理由、改革的先驱以及改革的困难和成效等等。可以说,这篇文章虽然没有在原来基础上深入,却完整地体现了胡适关于白话文运动的思想。译者查阅了1994年12月由耿云志主编、黄山书社出版的《胡适遗稿及秘藏书信》,1998年11月由欧阳哲生主编、北京大学出版社出版的《胡适文集》,同年12月由人民文学出版社出版的《胡适文集》,以及2003年9月由季羡林主编、安徽教育出版社出版的《胡适全集》,均未收录这篇文章,希望此文的发现可以为研究胡适及白话文运动、文学革命提供新的信息。
