网络"虚拟世界"质疑     

张诗博 《商丘师范学院学报》2007,23(5):111-112

从计算机网络的硬件的制造和软件的创制,到网络的运行与信息传播活动,最后再到网络的终端,不仅凝聚着人类的智慧,标志着现代科学技术的最新发展,而且整个过程的主体是具有社会属性的、现实的、具体的人。计算机网络在创造新的传播交流平台的同时,还深深地影响到网络终端主体的心理状态、思想观念和实际行为。因此,计算机网络不是一个虚拟的世界,而是现实社会的有机构成部分。  相似文献

方东美论道家艺术精神     

施保国  俞娟 《嘉应学院学报》2011,29(1):33-37

"诗哲"方东美极为重视道家的艺术精神。他以形象的比喻"太空"来描述道家妙不可言的胜境,此真理、真实之"太空"胜境,为道家艺术精神的指向。超越、解放与"坐飞机"升迁等,为道家艺术精神获取的途径。道家艺术精神运转无穷,像"同心圆"扩散一样,产生广泛的影响。  相似文献   

彩色图像的数字水印系统设计     

石红芹  吕方亮  刘遵雄 《实验室研究与探索》2011,30(5)

针对数字产品的版权保护问题,利用二维离散整数小波变换的快速性,结合人类视觉系统特性,开发了一种基于彩色图像新的、简单的、鲁棒性盲水印嵌入系统.系统可以将水印信息嵌入到不同整数小波分解级数下的彩色载体图像中去,具有嵌入速度快、安全性高的特点.首先将彩色载体图像由RGB彩色空间转换到YUV空间,再对y分量进行多级整数小波分解,然后分别将有意义的二值图像和字符串作为水印嵌入到不同级数小波分解后的低频域(LLn).算法选择了合适的水印嵌入位置,实验结果证明:系统使图像的不可见性好,所嵌入的水印对一般的图像处理攻击,如噪声、滤波、旋转、压缩等有较强的鲁棒性,系统实用性较强.  相似文献   

空间权内涵之探究     

姜瑜 《商丘职业技术学院学报》2011,10(4):28-29

空间是指土地上下一定范围的立体上的位置。对空间所享有的支配和利用的权利就是空间权。空间权指在空中或地中横切一断层而享有的权利,或者说是对土地地表之上下的一定范围内的空间享有的权利。空间权是独立的物权,包括空间所有权和空间利用权。  相似文献   

Torsional effect of space structure in frequent earthquakes     

WANG Xiu-li  JIN En-ping 《重庆大学学报(英文版)》2011,10(2):84-92

Taking a concrete frame supporting space structure as the research object, we systematically studied its lateral-torsion coupling effect of reverse problems in consistent earthquake excitation. Firstly, based on its reverse forms and features, we put forward a mechanical analysis model (flexibility layer model) and a calculation method using the response spectrum method and the weighted average method, and verified their validity and feasibility using case analysis. The result shows that the translation displacement change trend of the space structure is basically the same whether reverse exists in the supporting structure or not, but the supporting structure torsion has an effect on the displacement with a relative increase of 10?.  相似文献   

间阻思慕传深情——谈《诗经》中的“思慕诗”     

徐萍 《淮北职业技术学院学报》2011,10(4):61-63

爱情诗是《诗经》中的一种重要题材,主要是指恋歌以及和婚姻爱情生活相关的诗篇。在此主要以《诗经》中描写男女相思爱慕、征夫思妇情怀的诗歌为研究对象,以诗中描写的时空距离为切入点,试图对此类诗歌的创作动因、抒情艺术方式以及抒情艺术特征等问题作出简单的分析和探讨。  相似文献   

Examining features of how professional development and enactment of educative curricula influences elementary science teacher learning     

Ellen M. Granger  Todd H. Bevis  Sherry A. Southerland  Yavuz Saka  Fengfeng Ke 《科学教学研究杂志》2019,56(3):348-370

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in 4th—5th grades) that met the What Works Clearinghouse standards without reservations, teacher learning was conceptualized using four outcomes. Data were analyzed using standard single-level multiple regression models and possible mediation models for the teacher outcomes were considered using piecewise multiple regression and path analytic approaches. Treatment group teachers experienced greater increases in content knowledge, views of science inquiry, beliefs about reform-based teaching, and teaching self-efficacy than comparison group teachers. The findings indicate that what teachers learn from the combination of professional development and teaching with educative curriculum varies according to what their knowledge and beliefs are on entering the experience. Surprisingly, high entry-level self-efficacy was associated not only with lower learning gains for the teachers, but also for their students. Finally, teachers' space science learning and that of their students are implicated as mediators of the positive effect of the professional development and educative curriculum enactment on teacher beliefs about reform science teaching. This work refines and extends a theoretical framework of teachers' participatory relationship with curricula.  相似文献   

From safe spaces to communities of disagreement     

Lars Laird Iversen 《British Journal of Religious Education》2019,41(3):315-326

The idea of the classroom as a ‘safe space’ has been popular in education for at least two decades. More recently, the term has also been used by religious education scholars not least in the wake of the use of the term in the influential Council of Europe publication ‘Signposts’. In this article, I want to question the usefulness of the term ‘safe space’ within RE. The argument is not against many of the pedagogical aims and strategies that are referred to by the term ‘safe space’. However, the term is ambiguous, fraught with politicised controversy and promises more than in can deliver. These problems cannot be easily fixed by defining the term anew. The article is not only critical in its aim. It presents an alternative strategy. In the conclusion of the article, I suggest construing the RE classroom as a community of disagreement.  相似文献   

话语冲突与“心理空间”——《死者》中主人公康罗伊顿悟之心理动因探究     

薛海燕 《河西学院学报》2011,27(4):50-54,45

"顿悟"是爱尔兰作家詹姆斯·乔伊斯的名篇《死者》中的重要创作手法之一。运用法康尼尔(Fauconnier,G)认知语言学心理空间理论能有效挖掘人物顿悟之前的心理,从而进一步深化故事主题。在《死者》中,主人公康罗伊与三位女性之间的话语冲突使主要人物的心理空间发生了多次交错,促使康罗伊摈弃殖民地特权者身份,回归爱尔兰传统。康罗伊的精神复苏在深层次上象征着整个民族的新生。  相似文献
