论两宋时期的生子不举习俗

生子不举,即为生子不养育。两宋时期这一习俗尤为盛行,其存在时间之长,分布范围之广,在我国历史上实属罕见。究其原因,主要由农户的贫困、身丁钱的征收、财产继承关系的制约、厚嫁之风的盛行以及灾荒等造成。生子不举习俗的普遍存在限制了一些地区劳动力的增长、导致人口性别比例严重失调、增加了刑事诉讼案件,也败坏了宋朝社会伦理道德。     

High-Chern-number and high-temperature quantum Hall effect without Landau levels

The quantum Hall effect (QHE) with quantized Hall resistance of h/νe² started the research on topological quantum states and laid the foundation of topology in physics. Since then, Haldane proposed the QHE without Landau levels, showing nonzero Chern number |C| = 1, which has been experimentally observed at relatively low temperatures. For emerging physics and low-power-consumption electronics, the key issues are how to increase the working temperature and realize high Chern numbers (C > 1). Here, we report the experimental discovery of high-Chern-number QHE (C = 2) without Landau levels and C = 1 Chern insulator state displaying a nearly quantized Hall resistance plateau above the Néel temperature in MnBi₂Te₄ devices. Our observations provide a new perspective on topological matter and open new avenues for exploration of exotic topological quantum states and topological phase transitions at higher temperatures.

中国哲学对人类社会发展的功能意义

中国哲学的"和而不同"的思想对于化解不同国家、不同民族、不同社会、不同文明之间的矛盾,对于保存不同国家、不同民族、不同社会、不同文明的特色具有建设性意义。从人类社会意识、人类文化发展的规律来看,儒家大同世界的思想虽然已过去两千多年了,但其先进的思想光辉至今仍然明亮闪烁。     

中国现代远程开放教育的历史传统

中国现代远程开放教育的传统可以溯源于先秦。从旧时私学创办的形式里,可以看到丰富的现代开放教育的元素。古代以儒家学派为代表的教育思想,对现代远程开放教育教学方法的运用、教学手段的实施以及教学目标的制定等,均深有启迪。

谈谈汉语无主句的英译途径

汉语无主句是汉语言中常见的一种典型句型和独特的语言现象。由于英汉两种语言在句法结构上存在着差异,在进行汉语无主句的英译时,往往需要采取一些技巧,才能使译文符合英语语言的规范。文章通过大量的译例,探讨了汉语无主句的英译途径,旨在使译文既忠实于原文又符合英语表达习惯。     

“停课不停学”时期的在线教学研究——基于全国范围内的33240份网络问卷调研

新冠肺炎疫情期间,教育部发布"停课不停学"号召,各地纷纷响应并陆续出台相关政策,利用互联网教育资源开展教学。在此背景下,文章在全国范围内对区县教育管理者、学校管理者、教师、学生和家长进行了网络问卷调查,以了解"停课不停学"时期的在线教学情况和不同主体对在线教学的态度。基于此,文章总结了"停课不停学"时期在线教学存在的问题并提出了应对措施,以更好地服务于在线教学,确保疫情结束后在线教学的健康发展,并为统筹、协调全国力量开展在线教学以应对未来不可预见的公共危机提供参考。     

Holiday Play for Children with Disabilities in England: Access,Choice and Parents’ Views about Integration

Families with children with disabilities can feel isolated during school holidays and concerns exist that they face greater difficulties than families of children without disabilities in finding enriching activities for their child. In the context of national policies that encourage integrated play, local service commissioners in England require evidence on what sort of short breaks parents and children prefer. The parents of 99 children with disabilities and 43 children without disabilities attending various holiday play schemes in summer 2010 completed mailed questionnaires. Parents of children with disabilities reported more difficulty getting information, less choice of schemes and further distances to travel than parents of children without disabilities. Although 72% of parents of children without disabilities and 55.5% of parents of children with disabilities stated integrated schemes would be suitable for their child, open text comments provided weaker support. Variety of provision is required to meet all needs and preferences.
