Identifying Temporary and Permanent Gaps in Universal Service

This article examines the nature of the gap in household telephone penetration among Whites, Blacks, and Hispanics. By analyzing historic and current penetration levels of the radio, television, and telephone, it suggests that most information technology gaps are amalgamations of smaller socioeconomic trends and can be discerned and reduced only with careful historical analysis of both technology choices and living patterns. It proposes localized universal service strategies, since the penetration gaps are affected by a complex array of factors more particular to localities than to the country as a whole and as such must be investigated with rigor and caution if progress toward the elimination of penetration gaps is to occur.

WebQuests and collaborative learning in teacher preparation: a Singapore study

This research project aimed to introduce WebQuests to train special education preservice teachers in Singapore. The following research questions were posed: (1) Does the use of WebQuests in teacher preparation promote special education teacher understanding on Universal Design for Learning in accommodating students with diverse learning needs? (2) Are WebQuests useful tools that can enhance teacher’s higher-order thinking, engagement, creativity, and collaborative learning skills? (3) Does the use of WebQuests in teacher preparation foster stronger desires for teachers to integrate Information and Communication Technology in teaching and learning? Seventy-five preservice special education teachers responded to a survey questionnaire after experiencing WebQuest developed by the course instructor in teacher preparation program in Singapore. The majority of teachers indicated strong preference for WebQuest activities over traditional teacher-directed learning methods.     

审美视阈下的中国电视娱乐节目走向

电视作为现代社会中最具有影响力的媒体,在传达公共政策、引导社会舆论等方面发挥着举足轻重的作用。电视传媒是现代科技传播的重要标志,是最广泛的大众文化传播媒体之一。本文通过梳理中国电视娱乐节目的发展历程,论述了中国电视娱乐节目的发展的四个时期,最后,阐释了娱乐化电视节目的发展走向。     

"审美娱乐"范畴刍议

“审美娱乐”范畴作为审美文化语境中的一种普遍景观和重要特征,具有特定的内涵意义,它不同于一般意义上的“纯粹的娱乐”,而向“娱乐”范畴的深层意义上扩展,是一种审美层次上的心灵愉悦;在其美学特征上具有“审美快适性”和“审美解放性”,并产生一种“溶解性的美”,具有自身的积极意义;但是在承认“审美娱乐”的合理性的同时又不能放弃清醒的价值评判,对于当下娱乐文化中追求感官刺激和趋于媚俗的现状,应该进行必要和迫切的审美导向,以达到真善美的和谐统一。     

马尔库塞的社会文化批判观

马尔库塞作为西方社会的批判者,以其独到的眼光看到了资产阶级不仅在物质领域占有统治地位,更重要的是他看到了资产阶级已把统治延伸到文化领域。由此,他把马克思的批判理论重心从经济、政治领域转移到大众文化、哲学、意识形态领域中,力图通过批判资产阶级的大众文化、意识形态、哲学的统治,以达到争取恢复无产阶级的阶级意识和实现人的“普遍本质”的目的。我们在运用马尔库塞的理论考察我国文化时,应注意我国的国情和特殊的文化背景防止错误地运用其理论。     

论冯友兰的天地境界说

天地境界是冯友兰人生境界说的最高境界,它既有“真”的意蕴、“价值”的意义,还有终极关怀的作用。天地境界在去除利害之束缚、消除有无、动静、内外之分别的基础上,达到超死生、齐凡圣的境界。天地境界的旨归在于给人类以终极意义上的关怀,这对于建立个体人格、建构精神家园无疑具有不可忽视的意义。     

基于HyperMesh与ANSYS联合仿真下万向联轴器的模态分析

针对万向联轴器在高速工作环境下出现振动问题,以SWC-225CH型万向联轴器为研究对象进行模态分析。首先利用HyperMesh优越的前处理功能,对该模型进行网格、非线性接触、耦合处理。前处理完成之后,导入ANSYS软件中进行模态设置,并求出六阶振型图。从振型图中可以发现SWC-225CH型万向联轴器最大振型位置随着阶数变化而变化。通过Hypermesh和ANSYS联合仿真不仅减少前处理的时间,又可以保证其计算精度的准确性,为万向联轴器设计、优化、谐响应分析提供了理论依据。
