北周武帝孝陵出土玻璃珠的科学分析与研究

1993年8月,位于咸阳市底张镇陈马村东南约1000米处的一座古墓葬被盗掘,其后陕西省考古研究所于1994～1995年进行了发掘,根据出土的墓志石、印章以及墓室中发现的两套棺     

论唐墓壁画中的佛教题材

唐代在墓室中绘制壁画,不但是身份地位的象征,而且反映着当代人们的宗教取向。唐代佛教昌盛,华夏民族传统的丧葬习俗也深受影响,在表现形式上与魏晋南北朝时期不同,随葬明器大量减少,代之以墓室壁画和隐藏其中的佛教因素为主,并流传至今     

中日对抗与公共卫生事业领导权的较量——对"南满洲"铁路、港口中心城市的观察(1901-1911)

1905年日俄战争之后,日本在南满控制区域内的铁路、港口中心城市大力推进公共卫生事业,与此同时,中国官府也积极创办当地公共卫生事业,双方就公共卫生事业领导权展开激烈的竞争和较量,并在一定程度上改善了某些特定区域的卫生环境。然而,由于这是一种扩张/反抗的展开模式,在疾病治疗和预防疾病之外被赋予了更多的政治考量,致使城市贫民区与乡村的医疗卫生条件并未得到重点关注和大量投入,很长一段时间内该地区仍然疾病丛生,恶性传染病蔓延。在这个意义上,日本推进的公共卫生事务自然有其殖民主义扩张、帝国主义统治处心积虑、老谋深算的一面,中国官府和社会的自强卫生、救国医学则或可被视为一种不得已的推进方式。     

素质教育背景下的高中班级管理建设

一个班级的管理需要班级理念做支撑。要加强高中学生的各方面的教育,还应把学习作为教育学生的一条主线,在学习中对学生进行各方面的教育,对高中学生,一旦脱离了“学习”这条主线,一切教育都是枉然。     

20世纪80年代邓小平国家安全思想论析

20世纪80年代,邓小平继承和发展了毛泽东的国家安全思想,紧紧围绕以经济建设为中心,积极营造有利的国家安全环境,使中国经济迅速发展,综合国力和国际地位不断提升,国家安全得到了切实有力的保障。邓小平的国家安全思想是理性和务实的,适应了当时国内发展任务的需要,对中国的安全战略起过重大的指导作用,也为后来的国家安全决策提供科学的依据和借鉴。     

改革开放以来中国社会福利制度的嬗变

过去的30多年,有着鲜明计划经济烙印的社会福利制度随着经济转轨经历了从初始的起步探索,到后来逐渐转型和步入正轨的艰辛的改革历程。职工福利分解、社会福利社会化推进、社区服务普及、农村社会福利重构、适度普惠型福利探索等凝结为改革成果,初步形成了新型社会福利体系,但这些改革在社会福利的目标模式上是初级的、不全面的和不平衡的。面对变化的国情,处理好发展与公平的关系,构建适度普惠型社会福利制度,是中国社会福利的目标选择。     

Shake Table Test and Numerical Analysis of a Bridge Model Supported on Elastomeric Pad Bearings

Elastomeric pad bearings are widely applied in short- to medium-span girder bridges in China, with the superstructure restrained by reinforced concrete (RC) shear keys in the transverse direction. Field investigations after the 2008 Wenchuan earthquake reveal that bearing systems had suffered the most serious damage, such as span falling, bearing displaced, and shear key failure, while the piers and foundations underwent minor damage. As part of a major study on damage mechanism and displacement control method for short- to medium-span bridges suffered in Wenchuan earthquake, a 1:4 scale, two-span bridge model supported on elastomeric pad bearings were recently tested on shake tables at Tongji University, Shanghai. The bridge model was subjected to increasing levels of four seismic excitations possessing different spectral characteristics. Two restraint systems with and without the restraint of RC shear keys were tested. A comprehensive analytical modeling of the test systems was also performed using OpenSees. The experimental results confirmed that for the typical bridges on elastomeric pad bearings without RC shear keys, the sliding effect of the elastomeric pad bearings plays an important role in isolation of ground motions and, however, lead to lager bearing displacement that consequently increases the seismic risk of fall of span, especially under earthquakes that contain significant mid-period contents or velocity pulse components. It is suggested from the test results that RC shear keys should be elaborately designed in order to achieve a balance between isolation efficiency and bearing displacement. Good correlation between the analytical and the experimental data indicates that the analytical models for the bearing and RC shear key as well as other modeling assumptions were appropriate.     

英国废除《谷物法》刍议

皮尔政府废除《谷物法》体现了英国现代转型的时代潮流,此时《谷物法》失去了社会多数群体的支持,能否废除的关键取决于持不同立场的议员在议会内的博弈。谷物法的产生与废除都是某种特定的历史范畴,无论在废除谷物法问题上持赞成或反对立场的议员,他们代表的只是城镇或是农村的部分群体的利益,却同时伤害了农村的利益。《谷物法》不能简单地看成为一个阶级立法,赞同《谷物法》的不仅有土地贵族,也有农场主和耕地农。     

Spatial–temporal distribution and geographic context of Neolithic cultural sites in the Hanjiang River Basin,Southern Shaanxi,China

Understanding how to live successfully within our environment is among the most pressing challenges facing contemporary society. This paper probes the problem based on comparative analysis and discusses the relationship between the spatial–temporal distribution of the Neolithic cultural sites and the geographic context in the Hanjiang River Basin in the south of Shaanxi Province, China. Archaeological studies have identified 175 Neolithic cultural sites in the study area, with a sequence of Laoguantai (¹⁴C age 8–7 ka BP), Yangshao (¹⁴C age 7–5 ka BP) and the late period of the Neolithic Age (¹⁴C age 5–4 ka BP). The total number of archaeological sites, the distribution area and the density all showed an early ascending and later descending trend, but the proportion of the number of archaeological sites in the study area to the corresponding value of the entire Shaanxi Province declined sharply. Spatially, these sites were concentrated on the terraces of the Hanjiang River and its main tributaries with an altitude of 400–800 m. Multiple data were integrated to clarify the critical effects of tectonic and geomorphologic conditions on the distribution of the Neolithic sites. Further comparisons revealed the correlation of Holocene climate change and environmental evolution with the Neolithic cultural succession in the study area that ameliorated conditions to generally promote the development of the primitive culture while degeneration coincided with the culture's transition or interruption. The discussion on the origin of the primitive culture and the temporal–spatial distribution corresponding to the regional culture differentiation sheds light on the complex and dynamic human–nature interaction system during the Neolithic Age, thus emphasising the wider field-based investigation and high-resolution reconstruction works of the palaeoclimate and palaeoenvironment in the future.     

Constructing and practicing feminist pedagogy in Taiwan using a field study of the Twenty-Five Ladies Tomb

Drawing on theories of space, gender, and participatory learning, central concepts in feminist pedagogy, the author designed a university-level general-education course that took the Twenty-Five Ladies Tomb in southern Taiwan as the focus of a field study and class discussion. This local gendered site, which commemorates a 1973 ferry accident that killed 25 unmarried young women working in Kaohsiung, raises issues about patriarchy in Taiwan, gender inequities in traditional Han customs, and women's labor. The course relied on guided class discussions and focus-group discussions, culminating in a visit to the site. Face to face with the researched, the author not only built an inclusive and supportive relationship with students in the classroom, but also put her researcher's reflexivity into teaching practice. Research results indicate that the freedom of the class discussion format succeeded in breaking down the logic of binary opposition that accompanies the traditional gender duality of male/female. Avoiding a top-down teaching style also minimized students' resistance to perspectives emphasizing gender equality.
