论党在过渡时期的文化政策

党在过渡时期的文化政策 ,对解放精神生产力 ,促进中国文化的发展和繁荣 ;对变革文化制度 ,推动半殖民地半封建文化向有中国特色社会主义文化的变革 ;对转换文化结构 ,推进传统文化现代化 ,都发挥了巨大的作用。同时 ,这些文化政策也存在一些缺陷。     

无锡出土宋代绿髹漆钵的制作工艺研究

无锡八士镇宋代墓葬出土的绿髹荷花形漆钵是极为罕见的“绿沉漆”实物,利用三维视频显微系统、激光显微拉曼光谱、热裂解-气相色谱/质谱,对这件绿髹漆钵标本进行了分析研究。结果表明,绿髹荷花形漆钵经过制胎、批灰、髹底漆、髹红色以及绿色面漆的工序制作而成;其木质胎体为杉木属,漆灰以植物油和中国大漆作为胶结材料,而面漆则是中国大漆并添加了熟桐油作为助剂;红色漆膜呈色颜料为朱砂,绿色漆膜的呈色是由雌黄和靛蓝调配而成。这是对“绿沉漆”漆器制作工艺的首次科学鉴别。     

Social media reconstructions of urban identity during the COVID-19 pandemic

The COVID-19 pandemic has profoundly affected people in urban areas. This article reports on a comparative empirical study of the pandemic in Guangzhou and Xi’an in 2021 and analyses how residents responded to social media during the crisis. Using Baidu’s hot search time machine to search for hot topics related to the spread of disease during each outbreak of COVID-19, we collected 35 and 41 hashtags for Guangzhou’s and Xi’an’s epidemics, respectively. Based on a thematic analysis of those hashtags, we considered how residents reconstructed expressions of urban identity in both cities. We found that China’s unique official accountability system in local anti-epidemic practices led to stricter forms of top-down urban governance and that urban residents deployed forms of bottom-up agency in response. Our work provides a refined agenda for geographers and other social scientists to examine the interconnections among urban resilience, urban social responses to major public crises, and urban culture.     

Seismic vulnerability assessment methodology for slender masonry structures

ABSTRACT

Slender masonry structures such as towers, minarets, chimneys, and Pagoda temples can be characterized by their distinguished architectural characteristics, age of construction, and original function, but their comparable geometric and structural ratios yield to the definition of an autonomous structural type. These structures constitute a part of the architectural and cultural heritage. Their protection against earthquakes is of great importance. This concern arises from the strong damage or complete loss suffered by these structures during past earthquakes. Seismic vulnerability assessment is an issue of most importance at present time and is a concept widely used in works related to the protection of buildings. However, there is few research works carried out on developing the seismic vulnerability assessment tools for such structures.

This article presents a new method for assessing the seismic vulnerability of slender masonry structures based on vulnerability index evaluation method. The calculated vulnerability index can then be used to estimate structural damage after a specified intensity of a seismic event. Here, 12 parameters are defined to evaluate the vulnerability index for slender masonry structures. Implementation of this methodology is carried out in different types of slender masonry structures to develop vulnerability curves for these structure types.     

略论北魏时期的"上客"、"第一客"与招怀政策

招怀政策在北魏王朝政治与文化建设中发挥了极其重要的作用,大批来自周边政权与民族的人士进入北魏王朝后受到优待与重用,从而成为北魏政权及文化建设中的重要力量。本文主要从文献记载中“上客”与“第一客”的事迹分析入手,试图对北魏招怀政策总体特征与核心原则进行简要的总结与归纳,力求从一个侧面阐发北魏招怀政策的重要价值与贡献。

《海录》作者、版本、内容新论

《海录》是记述当时海外邻近国际航线的各国、各地区、各城市见闻的作。《海录》对南中国海岛屿、航线的记述,对研究19世纪初中国南海海疆具有重要价值。《海录》是清代记述世界各大洲、各国、各地状况最多最全的作之一,是清代最早记述西方工业明的作之一,对近代以林则徐、魏源为代表的思想家产生过重要影响。     

清朝消极治台政策与台湾行政区划的设置

清朝统治者攻占台湾的目的是为了铲除反清势力在海上的根据地,而非开发台湾的自然资源、利用台湾的地理优势。因此,清廷采取了消极的治台政策。本文分析了清廷消极治台政策的产生过程,及由此导致台湾行政区划设置迟缓等恶劣结果。
