高校英语网络教育资源建设研究

本文基于一项针对8所开设英语学历教育的中国高校网络教育学院在资源开发方面的调研,在深入分析数据的基础上提出这一领域——特别是在多媒体光盘和网络课件这两类网络教育特色资源的开发和使用上——存在的三对焦点问题,即“流水线”模式与“多元团队”模式的对立“;简单转换”模式和“特殊开发”模式的对立;高成本电子产品开发与学生低接受度和使用率的对立,本文分析了这三对焦点的成因,以及其对于中国高校英语网络教育在资源开发的启示。     

荧光法测定羟基自由基及中草药抗氧化性

L-苯丙氨酸本身具有较弱的荧光,在羟基自由基的作用下能产生较强的荧光,其激发波长和发射波长分别是277 nm和306 nm.很多中草药提取物可以清除溶液中的羟基自由基,从而使溶液的荧光增强程度降低.据此,建立了一种测定中草药抗氧化性的方法.研究了L-苯丙氨酸-Fe2 -H2O2体系产生羟基自由基的最佳条件,并测试了赤芍、钩藤、姜黄、炒蒺藜四种中草药水提物的抗氧化活性.     

Perceived Parental Influence on Mathematics Learning: A Comparison Among Students in China and Australia

This paper explores the perceived parental influence (PPI) on mathematics learning among over 700 students across three year levels (Years 5, 7, 9) in China and Australia. It was found that the PPI of students was less strong as year levels increased in both countries. Students in China had stronger perceived parental encouragement and higher perceived parental educational expectation than students in Australia. The PPI of students from different home language backgrounds was also investigated. Students in China demonstrated stronger perceived parental encouragement and parental expectation than English speaking students and other language speaking students in Australia, and they also demonstrated stronger perceived parental expectation than Chinese speaking students in Australia, and similar perceived parental encouragement. Within the three groups of students in Australia, Chinese speaking students and other language speaking students demonstrated similar levels of perceived parental encouragement and expectation, but they both demonstrated a higher level of perceived parental encouragement and expectation than English speaking students. Possible reasons for the similarities and differences between the different groups of students were discussed.

An adaptive strategy for controlling chaotic system

This paper presents an adaptive strategy for controlling chaotic systems. By employing the phase space reconstruction technique in nonlinear dynamical systems theory, the proposed strategy transforms the nonlinear system into canonical form, and employs a nonlinear observer to estimate the uncertainties and disturbances of the nonlinear system, and then establishes a state-error-like feedback law. The developed control scheme allows chaos control in spite of modeling errors and parametric variations. The effectiveness of the proposed approach has been demonstrated through its applications to two well-known chaotic systems: Duffing oscillator and Rössler chaos.
