摘要：In recent years, Wuzhen, a Ming-Qing style water town located south of the Yangtze River, has quickly become one of the most popular tourist destinations in China. The success of Wuzhen was so influential that the term ＂Wuzhen Model＂ quickly became a buzzword in Chinese economic and cultural discourses. Promoters of Wuzhen have claimed that it embodies both tradition and modernity, therefore representing the best of China. While Wuzhen was first reconstructed as a ＂living museum＂ of Chinese cultural tradition to attract tourists, it increasingly started to claim itself as a leading ＂smart town＂ for China＇s future development. Moreover, the so-called Wuzhen Model fits seamlessly into China＇s overall strategy of projecting its soft power both domestically and abroad. The purpose of this paper is to examine how Wuzhen was culturally constructed and how it helped to project China＇s soft power. It also examines how Wuzhen was perceived abroad, focusing primarily on major English-speaking countries including the United States, the United Kingdom, and Australia, to understand its impact on China＇s soft power,

摘要：本文旨在从形式和概念两方面探析中世纪早期中国巍峨的佛教建筑的南亚原型。笔者认为,印度高耸神庙建造背后的几个中心概念,即祭坛、山和宫殿,对佛塔建筑的重要意义不逊于塔中供奉的舍利。这类神庙建筑依托充满精神能量的设计蓝本,其形制和平面类似于最原始的祭坛和南亚宇宙观中巍峨壮观的须弥山,围绕垂直中轴形成多层级宫殿建筑,以承袭作为世界始源的第一祭祀所拥有的原动力。一座完美的宇宙山就此构建而成,其外部表现为巍峨高耸的宫殿,以作为供奉佛教或是印度教神祗的圣殿。其落成后,对再生之灵的祭祀崇拜不再局限于特定地方圣地(南亚或东亚),信徒在此也可以真切感受到圣山的精神氛围。

摘要：We describe a few mathematical tools which allow to investigate whether air-water interfaces exist(under prescribed conditions)and are mechanically stable and temporally *** terms of physics,air-water interfaces are governed by the Young-Laplace *** they are surfaces of constant mean curvature which represent solutions of a nonlinear elliptic partial differential *** explicit solutions of this equation can be obtained only in very special cases,it is -under moderately special circumstances-possible to establish the existence of a solution without actually solving the differential *** also derive criteria for mechanical stability and temporal persistence of an air *** we calculate the lifetime of a non-persistent air ***,we apply these tools to two examples which exhibit the symmetries of 2D *** examples can be viewed as abstractions of the biological model represented by the aquatic fern Salvinia.

摘要：The present study aimed at determining whether short-term exposure to art in shared common areas in congregate housing units could affect health and health determinants among the residents. Ten residents (mean age 80.4 years) at one block were exposed to visual art environmental enrichment in common areas over a period of three months. Thirteen persons (mean age 86.6 years) living in another block played in-house boule. Cornell’s test, Mini-Mental tests (MMT), and face recognition test were performed to assess depression, cognition, and episodic memory, respectively before and after the intervention. The results show that visual art environmental enrichment in common areas and lack of stimulating and guiding dialogues show a change in depression scores in the intervention group (p = 0.018) and the control group (p = 0.009). MMT scores improved only in the control group (p = 0.003). No changes in episodic memory in any of the groups were observed. It could be concluded that in order to obtain a positive result of short term visual art environmental enrichment, guiding art dialogues conducted by nurses, as described in previous research, should be added to visual art environmental enrichment in healthcare settings.

摘要：以河南省为例,对2020年1月21日—2020年3月29日的新冠肺炎确诊病例进行性别、年龄统计,以日发病数为基本单位对其进行时序与特征分析;同时以病例患者所在区、县地理位置为基本单元,采用回顾性时空扫描统计量方法对该时期河南省新冠肺炎疫情进行时空聚集性分析,并利用地理探测器探究了影响疫情的主要自然环境和社会经济要素。结果表明,河南省新冠肺炎疫情时空聚集的重点区域是1月底至2月上旬的南阳、信阳、驻马店部分县区,主要受输入型病例、人口密度因素的影响。因此,建议河南省新冠肺炎疫情防控应当重点关注输入型病例较多、人口密度较大的地区。
