近年来秦汉道制研究概述     

安梅梅 《青海师专学报》2011,(4):57-59

道是秦汉政府管理少数民族的一种地方行政建置,相当于县。文章对近年来秦汉道制的研究状况进行了概述,主要以学术界关注较多、争议也较多的几个问题为切入点,即关于道制的起源、道制形成的时间、道的数目、道与县的关系。对这几个问题的研究,学者们虽各抒己见,取得了比较丰硕的成果,但很多问题仍存在争论,未能达成共识。  相似文献   

英语主语误用与中式英语     

安晓杰 《金华职业技术学院学报》2011,11(1):29-31

英语与汉语分属两个不同的语系。英语学习者在学习英语的过程中将本族的语言习惯和思维定势移植到英语学习中,形成母语负迁移。学生中式英语的根源即在于此。主语误用是造成中式英语的原因之一,具体表现为三种主语误用现象,即混淆主题与主语、主语缺失和主语使用不当。  相似文献   

论新时期实验话剧的荒诞性     

姜南 《金华职业技术学院学报》2011,11(2):79-83

当代意识的崛起和强化必然引起文学艺术自身发生嬗变。新时期以来,实验话剧在表现手法上勇于探索、敢于借鉴、立足实验的精神即是这种当代性渗透的结果。新时期实验话剧的创作与演出中出现的荒诞的艺术手段,不仅丰富了实验话剧的表达空间和艺术表现,也有力地拓展了实验话剧的开放意识、生命意识、思想内涵。  相似文献   

概念教学中数学思想方法的渗透     

汪楠 《宜春学院学报》2011,33(12)

数学概念的形成过程是一个归纳、概括、抽象的过程,因此概念的教学过程是一个探究的过程。数学概念从其形式上看,它是中学教学的表层知识,但是一个数学概念的背后往往蕴含着丰富的数学思想。在概念教学中注意数学思想方法的渗透,可以完成数学概念和数学思想方法的双重教学。  相似文献   

Understanding students’ engagement in MOOCs: An integration of self-determination theory and theory of relationship quality     

Yongqiang Sun  Linghong Ni  Yiming Zhao  Xiao-Liang Shen  Nan Wang 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(6):3156-3174

Although Massive Open Online Courses (MOOCs) attract millions of people to enroll in their courses, the completion rate for most courses is very low. A majority of MOOCs students are not fully engaged in MOOCs, thus leading them to quit in the early stage of the courses. Therefore, it is important to investigate students’ engagement in MOOCs. Drawing on self-determination theory and the theory of relationship quality, this study proposes a model that conceptualizes the MOOCs engagement as consisting of psychological engagement and behavioral engagement and explores the antecedents of students’ engagement in MOOCs. The research model is tested using data collected from 374 students of Chinese University MOOC. The results show that fulfillment of three basic psychological needs for autonomy, competence and relatedness have significant positive effects on intrinsic motivation, increasing students’ psychological engagement in MOOCs. Relationship quality significantly predicts students’ psychological engagement, and psychological engagement promotes behavioral engagement in MOOCs. Implications for research and practice as well as limitations of this study are discussed finally.  相似文献   

Walking backwards into the future: Indigenous wisdom within design education     

Nan O’Sullivan 《Educational Philosophy and Theory》2019,51(4):424-433

This research parallels Tongan academic Hūfanga ‘Okusitino Māhina’s assertions in the 1994 Contemporary Pacific article Our Sea of Islands, that ‘People are thought to walk forward into the past and walk backward into the future, both taking place in the present, where the past and the future are constantly mediated in the ever-transforming present’ alongside those of Professor Terry Irwin and fellow Transition Designers in which they discuss the use of Indigenous Wisdom to enable designing for the Long Now as defined by Brand in his 1999 book The Clock for the Long Now: Time and Responsibility. In the 2015 Transition Design Monograph Irwin asserts that, ‘Transition Design draws on knowledge and wisdom from the past to conceive solutions in the present with future generations in mind’. This paper draws on the pre-industrial wisdom of indigenous knowledge, specifically that of the Pacific regions, Moana, who have lived and designed sustainably in-place for generations to illustrate the value it holds for the formulation of sustainable and sustaining futures.  相似文献   

计算流体力学软件在汽车气动问题研究中的应用     

张楠 《重庆职业技术学院学报》2011,20(2):125-127

汽车在行驶过程中受到空气的作用力,会对汽车运动产生影响。汽车气动特性的研究是汽车设计研发的重要内容,随着计算机技术与数值计算方法的发展,计算流体力学（CFD）在汽车气动特性的研究中得到日益广泛的应用,特别是各类计算流体力学商业软件使其参与工程设计成为可能。文章在介绍计算流体力学的基础上,结合实例对计算流体力学软件在汽车气动问题研究中的应用进行了探究。  相似文献   

基于PCA和ANFIS的黄土湿陷系数预测     

安宁 《深圳职业技术学院学报》2011,10(1):28-31

运用人工智能原理,提出一种基于主成分分析法（PCA）与自适应神经模糊推理系统（ANFIS）的黄土湿陷系数预测方法．首先通过主成分分析对黄土的物理指标提取主成分,以消除变量间的相关性和减少模型输入量的目的;再利用神经网络的高自适应性和模糊推理系统的推理能力建立ANFIS模型,提出一种新的黄土湿陷性预测方法．通过实测数据和预测数据的对比分析,平均误差0．29％,最大误差20％,在工程上可以接受的范围,实例说明这种预测方法是可行的．  相似文献   

基于BP神经网络和AR模型的人口预测     

贾楠  胡红萍  白艳萍 《商丘师范学院学报》2011,27(3):6-9

利用MATLAB编程软件,分别建立BP神经网络和AR模型,采用全国出生率,死亡率,老年抚养率等9个指标作为样本,分别对BP网络和AR模型进行训练,预测5年后的人口数量.结果表明这两种方法预测人口均是可行的,效果较好,误差很小,但是AR模型较适合线性预测,而BP网络适合较非线性预测.  相似文献   

陆机作品用韵考     

安牧阳 《南宁师范高等专科学校学报》2011,(4):92-94

陆机现存作品十卷,大部分为韵文,其作品用韵,可以归纳系连出37个韵部,基本与周祖谟先生考证的魏晋宋时期韵部相吻合,但是亦有比较多的韵部混用现象。研究陆机作品用韵情况对于了解魏晋时期音韵,特别是西晋音有着重要的参考价值。  相似文献
