教育是家庭和个体阶层流动的重要渠道,也是一国人力资本积累的重要途径。伴随经济社会转型,重组家庭规模不断增加,而家庭结构变动对子女受教育影响的定量研究却付之阙如。文章首次采用CHARLS(2014)微观数据研究了家庭重组对子女受教育水平的影响。结果显示:(1)与完整家庭相比,重组家庭子女受教育水平降低约12.18%–15.5%,父母较高的受教育水平可以减缓但并不能消除这种差异。(2)家庭重组对男女存在显著差异,其中男、女受教育水平分别下降约14.26%和7.44%。(3)文章进一步从重组家庭的组合类型研究了性别差异背后的原因,发现与生父继母型家庭相比,生母继父型家庭使得男孩的受教育水平降低约24.21%;但对女孩而言,家庭重组类型并不存在显著差异。研究结果表明,在讨论未成年人受教育水平问题时,需要更加关注家庭结构和重组类型所产生的影响。

学生的课堂参与程度直接影响教学效果。为了解决英语大班授课学生表现被动的问题，文章以外语教学心理学理论为依据，通过采取平时成绩与课堂参与相结合的激励策略，进行了为期8个月的教学研究实践，并以问长访谈的形式调查了这一策略对课堂参与的影响。根据数据分析结果，初步得出以下结论：平时成绩激励策略有助于激发学生的课堂参与意识；学习水平较差者课堂参与的愿望更强；课文段落背诵、对话角色表演被认为最有利于提高语言技能；男生对课堂活动的自我评价均低于女生。

中华眼科杂志 2023年第3期59卷 237-241页

作者：郭曦谢培英北京远程视觉视光眼科北京100027

角膜塑形术是控制青少年儿童近视发展的有效方法之一,通过眼睑对塑形镜片产生的机械压力和塑形镜片下泪液产生的液压效应对角膜曲率或形态进行重塑,达到矫正屈光不正和控制近视发展的效果。泪膜是结膜囊中均匀分布的薄层液体,配戴角膜... 详细信息

角膜塑形术是控制青少年儿童近视发展的有效方法之一,通过眼睑对塑形镜片产生的机械压力和塑形镜片下泪液产生的液压效应对角膜曲率或形态进行重塑,达到矫正屈光不正和控制近视发展的效果。泪膜是结膜囊中均匀分布的薄层液体,配戴角膜塑形镜可导致泪膜稳定性下降,从而对角膜塑形术造成影响。本文汇总国内外相关研究结果,旨在梳理和探讨泪膜稳态对角膜塑形镜的验配、塑形效果、配戴安全性和视觉质量等方面的影响,阐明泪膜稳态对角膜塑形术的重要性,为临床开展工作和相关研究提供参考。

With the global commercialization of the fifth-generation(5G) network, many countries, including China, USA, European countries, Japan, and Korea, have started exploring 6G mobile communication network, following the tradition of “planning the next while commercializing one generation”. Currently,studies on 6G networks are at the infancy stage. Research on the vision and requirements for 6G is still ongoing, and the industry is yet to clarify the key enabling technologies for 6G. However, 6G will certainly build on the success of 5G. Therefore, developing high-quality 5G networks and seamlessly integrating 5G with verticals are the priorities before 2030, when 6G is projected to be commercialized. Also, global 5G standards will keep evolving to better support vertical applications. As a milestone, the Third-Generation Partnership Project(3GPP) published Release 16 in July 2020, which continuously enhanced the capabilities of mobile broadband service based on Release 15 and realized the support for low-delay and high-reliability applications, such as Internet of Vehicles and industrial Internet. Currently, 3GPP is working on Releases 17 and 18, focusing on meeting the demands of medium-and high-data-rate machine communication with low-cost and high-precision positioning, which will be published in June 2022. Thus, 6G networks will further expand the application fields and scope of the Internet of Things to accommodate those services and applications that are beyond the capabilities of 5G networks. Herein, we present our vision, application scenarios,and key technological trends for 6G networks. Furthermore, we propose several future research opportunities in 6G networks with regard to industrialization and standardization.
