含约束反力情况下自然坐标系与直角坐标系的等效性及差异性

质点曲线运动的动力学问题,在运用牛顿定律解题时,既可选用直角坐标系,又可选用自然坐标系。由于自然坐标系本身特点,其用在含有约束反力解题时,约束反力只出现在一个方向的动力学方程中。而在直角坐标系中描述问题,有助于对问题性质的认识和从几个运动方向独立求解。     

民国时期老子研究风貌管窥--《老子哲学之研究》阅读札记

在民国时期,伴随着中国现代化的进程,西方近现代学术开始大量传入中国,并为中国学术界所接受。随着"哲学"一词及其观念的传入,"老子哲学"研究一词开始频繁出现在民国时期老子研究的各类文章和书籍中,一个不同于封建时代的老子研究范式逐步被确立起来,其中许多观念一直延续至今。从金声这本名不见经传的小册子中,我们能够感受到中西思想强烈撞击的时代背景下老子研究的风貌。     

再论集体经营性建设用地信托之法构造

集体经营性建设用地使用权是一种用益物权,其可转让性得到了新修订的土地管理法的承认,可以成为集体经营性建设用地信托的信托财产。 集体经营性建设用地信托关系中的委托人和受益人都是农民集体。 农民集体作为委托人时,由于不具备我国信托法要求的民事行为能力,所以,农民集体的委托行为往往可以由经过其授权的集体经济组织代理。 集体经营性建设用地信托的受托人一般采取信托机构的形式,并有两种模式可以选择,即由政府出资成立的信托机构和商业信托机构。 前者具有一定的现实意义,而后者代表了受托人未来的发展趋势。     

Classroom

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. Wemay suggest strategies for dealingwith them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.     

Unexpected changes of itinerary – adaptive functioning difficulties in daily transitions for adults with autism spectrum disorder

Adaptive functioning skills, also known as adaptive behaviours, refer to a multifaceted concept defined as behaviours necessary for age-appropriate, independent functioning in social, communication, daily living or motor areas. In light of the growing population of children with ASD who will eventually become adults, increased understanding of adaptive functioning during the transition to adulthood is of importance, but current research in this area lacks first-hand evidence presenting adaptive skills difficulties among older adolescents and adults with ASD. This article focuses on adaptive functioning skills in daily transitions for adults with Asperger’s syndrome (AS) or high-functioning autism (HFA). It draws on evidence from 12 interviews with individuals on the autism spectrum age 16–43, and 2 focus groups with 8 family members of people affected by ASD. Particular emphasis is placed on impact of adaptive functioning difficulties on well-being and quality of life for adults with ASD. Grounded theory approach has been used to analyse the gathered data. Interviewees reflected on daily challenges associated with unexpected changes in routine, sensory difficulties and social interactions. These in turn had an impact on their adaptive functioning skills by introducing complications in the process of making transitions between different contexts and decreasing interviewees’ ability to tackle challenges of daily life. Importance placed on societal expectations towards meeting bespoken standards and conforming to norms ruling the structure and interactions of daily life were also widely discussed. Frequently such expectations did not allow for factoring in the developmental nature of ASD and related difficulties, which as a result triggered additional complexity in managing daily transitions for adults on the spectrum. Further research addressing adaptive functioning skills in daily transitions for adults with ASD is needed.     

加强实践环节的铁路线路课程设计探索

线路课程设计是一门综合运用理论和专业知识的实践课程,对工程实际经验依赖性很强。本文分析了目前铁道工程线路课程设计培养现状,论述了加强实践环节的必要性,并开展了加强赴现场模拟踏勘、邀请线路设计专家入校讲解等尝试,以期为类似实践性较强的课程设计提供参考。     

沉默权中国化所产生的问题及其对策

沉默权的中国化是一个把根源于西方文化传统的法律制度“移植”到中国并和中国的现实相结合且良性运行的过程。因此，沉默权的实行一定要和中国现实“对接”，否则盲目引进就会“水土不服”，甚至“南橘北枳”。沉默权的中国化会在立法、司法及其人们观念方面产生问题，并且就此提出相应的对策。     

义务教育阶段择校权利的认识与思考

学生择校权利的扩大符合我国教育政策和法规，符合义务教育的基本精神，是在我国现阶段促进教育平等的理性选择。扩大义务教育阶段学生的择校权利要大胆借鉴国际上有关国家的经验，充分考虑我国的现实国情，遵循点带面、公立和民办学校一视同仁的原则，采取建立规范的择校机制、进行学区调整和重点学校改革等的对策。     

知识产权滥用反垄断制度的理论初构与立法思考

一般情况下，知识产权为反垄断法所宽容，其垄断是合法的。知识产权滥用是民法上“权利滥用”的具体方式之一，知识产权法本身对其有许多限制。本文试图在反垄断法的理论框架内，初步构建知识产权领域反垄断的理论体系。     

现代化中的农民问题

农民问题伴随现代化进程始终,只有在一个国家充分实现城市化后才能最后解决。西欧、拉美等地的农民转变受到其历史与环境上的特殊条件的影响,而东亚的“小农制”模式缓和了农民在现代化进程中所难免遭受的苦难,对我们具有重要的借鉴意义。解决我国目前的农民问题,需要新的思路:尤其是转向主要在城市解决农民问题而不只是在农村解决,转向主要依靠个人与社会来解决而不是像以往那样只依赖于政府与官员。
