不同时代的盗火者--中庸的孔子与尖刻的鲁迅

本文试图在一个较大的可包容的空间内，以历史的纵深感和横向的视点游移性，来探求两住文化英雄——孔子和鲁迅的异同。通过对他们人生经历、处世态度、革新思想、毕生追求等方面的对比，来揭示他们对自身及民族命运的自觉．他们主动担当起重建文化秩序的重任，努力寻找着一条文化的超越之路，昭示出历史不同时代的最大机遇。     

Differentials in Mathematics Achievement among Eighth-Grade Students in Malaysia

This paper examines differences in mathematics achievement among eighth-grade students using a secondary analysis of the data. The students, who are from Malaysia, had participated in the Trend International Mathematics and Science Study (TIMSS) 1999. A series of school, home, demographic and socio-economic variables were used to investigate the differences in the mean student mathematics scores. Evidence from the data shows that gender, the language spoken at home, expected educational level, family background, and home educational resources and aids have a significant influence on the students’ level of mathematics achievement.     

Improving mobile learning with enhanced Shih＇s model of mobile learning

More recent motivational research focuses on the identification of effective techniques for enhancing instructional design and meeting the needs of diverse student populations （Wlodkowski R. J., 1981）. Learning-motivation researchers are applying some of the same theories and concepts found to be effective in industry to the development of motivational models that enhance the teaching-learning environment. One of such models is the Attention Relevance Confidence Satisfaction （ARCS） model of motivational design developed by John M. Keller （Small Ruth V., 2007）. The continuous improvement in handheld devices technologies has led to a new learning paradigm called mobile learning which involves the delivery of learning contents to learners utilizing mobile computing devices. Handheld devices, however, have constraints which limit their use for effective learning. Towards improving the effectiveness of mobile learning is a new mobile learning model proposed by Shih on which instructional designs for mobile learning can be based to facilitate mobile learning design and to achieve better mobile learning outcomes （Yushin E. Shih ＆ Dennis Mills, 2007）. Shih＇s model is based on Graphical User Interface （GUI）. This paper presents an enhanced Shih＇s model for effective mobile learning outcome in a university environment by making provision for instructional design to include online library search for both e-books and audio books using collaborative filtering algorithm to aid the search and posting and reading of testimonials about positive mobile learning outcomes so as to encourage other mobile learners. It also incorporates the use of Voice User Interface （VUI） to access the learning portal in order to overcome mobile devices interface limitations in addition to Graphical User Interface （GUI） proposed by Shih, so as to cater for the learning needs of the blind and the visually impaired.

文章对3.7 A GeV 16^O束流与核乳胶相互作用（3.7 A GeV 16^O-Em）所产生的次级粒子的平均自由程进行了初步测量和分析,给出了射弹分布,并利用另一种统计方法对实验数据进行了处理,没有发现反常子存在的迹象。     

翻译的中庸之道——从《罗密欧与朱丽叶》的两个中译本看归化与异化策略的运用

归化与异化两种翻译策略的争论在翻译史上一直相持不下,通过对朱生豪和梁实秋两位翻译大家的《罗密欧与朱丽叶》译本的比较,可以看出这一对互为矛盾的翻译策略的优劣,以及中庸之道的有机结合是缓解二者矛盾的可行之策。
