英法中动结构对比及认知动因

中动结构是语言中一种比较普遍的现象,它具有主动的形式和被动的含义。文章通过分析英法两种语言的中动结构,论述了它们的相似之处,同时揭示了其后的认知动因。文章还指出,其差异主要由法语中动结构的中动语素se导致,其天然的被动含义使其能产性和使用范围大大高于英语中动结构的用法。

A Critical Review of Motivation in Second Language Acquisition Research

As one of the major factors affecting second language learners＇ success to their acquisition achievement, motivation has been examined in a wide variety of research papers. It is thus instructive to conduct a critical review of both theoretical and empirical developments in SLA research from over the last few decades. This approach will provide a broad, and integrated perspective onto the current understanding of the complex topic of motivation. Such an undertaking is valuable for teachers, and researchers alike, in developing useful teaching methods, and finding future avenues of SLA motivation research respectively.The following paper provides an overview of recent theoretical and empirical findings, examines some of the problems and contradictions found in current SLA research, and gives an initial departure point for future directions of research in the area of motivation. The paper concludes with a discussion of some of the implications for teachers, and possible classroom strategies that are drawn from the current body of motivation research.

后冷战时代印美关系的发展及动因

后冷战时代,印度与美国在政治关系走向融洽,同时高层交往不断、经济合作得到发展、军事交流恢复与加强,使印美关系得到改善与发展。美国与印度在后冷战时代都把对方看成是实现其战略目标的对象,这就是在后冷战时代美国与印度的关系不断改善与升温的动因。     

英汉语中动结构与认知动因研究

英汉两种语言都存在中动句式。通过比较英汉中动句构造的异同点并从认知语言学图形／背景句法分析的角度出发，认为受事成为中动句的主语，是由于受事的内在特性而突显；其状语在句中不可或缺，也成为突显部分。     

高校图书馆读者违章行为及心理分析

高校图书馆读者违章行为的表现形式主要有四种：（１）损害文献资源；（２）不守阅览规则、违反借阅制度；（３）不爱护公共设施、破坏环境卫生；（４）不尊重工作人员及其劳动。违章行为受违章动机和违章心理的支配，每一种违章行为的背后都有它的动机，每一种违章行为过程中都进行着不同的心理活动，产生着不同的心理反映，认识和分析这些违章动机和心理反映，可以帮助我们查寻违章行为产生的根源和屡禁不止的原因——主观的、客观的；自身的、社会的，便于加强对读者的教育引导，然后进一步制定出纠正和防止违章行为的措施。

Optimized LDPC differential-encoded 16QAM scheme for high-speed transmission systems

The 16-ary quadrature amplitude modulation （16QAM） is a high spectral efficient scheme for high-speed transmission systems. To remove the phase ambiguity in the coherent detection system, differential-encoded 16QAM （DE-16QAM） is usually used, however, it will cause performance degradation about 3 dB as compared to the conventional 16QAM. To overcome the performance loss, a serial concatenated system with outer low density parity check （LDPC） codes and inner DE-16QAM is proposed. At the receiver, joint iterative differential demodulation and decoding （ID） is carried out to approach the maximum likelihood performance. Moreover, a genetic evolution algorithm based on the extrinsic information transfer chart is proposed to optimize the degree distribution of the outer LDPC codes. Both theoretical analyses and simulation results indicate that this algorithm not only compensates the performance loss, but also obtains a significant performance gain, which is up to 1 dB as compared to the conventional non-DE-16QAM.
