新时期农民增收举措再探讨

当前，农民增收困难已成为农村经济全面发展的“瓶颈”约束。农民收入增长缓慢既有政府宏观调控方面的原因、中观农业产业本身的原因，又有农民素质方面的原因。增加农民收入，政府必须加大农业支持力度，改变农村经济增长方式，全面提高农民素质。     

DSU报复制度的显著改进及我国的应对策略

传统国际法上的报复多以单边报复形态存在，滥用现象十分严重，威胁和损害到正常的国际法律秩序。由于存在着制度上的缺陷，GATT不仅未能从根本上解决报复滥用问题，而且限制了报复威慑作用的发挥。DSU通过改进规则和程序，强化多边体制，不仅充分地发挥了报复的威慑作用，而且还有效地管制了报复。该制度会给我国WTO争端解决的实践产生直接或者间接的影响，我们应认真研究应对策略，以维护我国的贸易利益和经济安全。     

对称性在物理解题中的应用

在各种物理模型、物理现象、物理规律中，普遍存在着和谐而优美的对称性。对称法就是利用给定物理问题在某一部分的特征，来推知其对称部份相同的特征。利用这一思路来分析和求解问题，可使分析问题的思路变得清晰，解决问题的步骤变得简捷。而且还可把一些表面上不具对称性的问题转化成具有对称性的问题，以便于求解。中学物理中的对称可有以下几种情况。     

Chinese and Canadian Children's Evaluations of Lying and Truth Telling: Similarities and Dfferences in the Context of pro-and Antisocial Behaviors

The present study compared Chinese and Canadian children's moral evaluations of lie and truth telling in situations involving pro- and antisocial behaviors. Seven-, 9-, and 11-year-old Chinese and canadian children were presented 4 brief stories. Two stories involved a child who intentionally carried out a good deed, and the other2 stories involved a child who intentionally carried out a bad deed. When story characters were questioned by a teacher as to who had committed the deed, they either lied or told the truth. Children were asked to evaluate the story characters' deeds and their verbal statements. Overall, Chinese children rated truth telling less positively and lie telling more positively in prosocial settings than Canadian children, indicating that the emphasis on self-effacement and modesty in Chinese culture overrides Chinese children's evaluations of lying in some situations. Both Chinese and canadian children rated trugh telling positively and lie telling negatively in antisocial situations, reflecting the emphasis in both cultures on the distinction between misdeed and truth/lie telling. The findings of the present study suggest that, in the realm of lying and truth telling, a close relation between sociocultural practices and moral judgment exists. Specific social and cultural norms have an impact on children's developing moral judgments, which in turn, are modified by age and experience in a particular culture.

The Intellectual Structure of Research on Educational Technology in Science Education (ETiSE): A Co-citation Network Analysis of Publications in Selected Journals (2008–2013)

The main purpose of this paper is to investigate the intellectual structure of the research on educational technology in science education (ETiSE) within the most recent years (2008–2013). Based on the criteria for educational technology research and the citation threshold for educational co-citation analysis, a total of 137 relevant ETiSE papers were identified from the International Journal of Science Education, the Journal of Research in Science Teaching, Science Education, and the Journal of Science Education and Technology. Then, a series of methodologies were performed to analyze all 137 source documents, including document co-citation analysis, social network analysis, and exploratory factor analysis. As a result, 454 co-citation ties were obtained and then graphically visualized with an undirected network, presenting a global structure of the current ETiSE research network. In addition, four major underlying intellectual subfields within the main component of the ETiSE network were extracted and named as: (1) technology-enhanced science inquiry, (2) simulation and visualization for understanding, (3) technology-enhanced chemistry learning, and (4) game-based science learning. The most influential co-citation pairs and cross-boundary phenomena were then analyzed and visualized in a co-citation network. This is the very first attempt to illuminate the core ideas underlying ETiSE research by integrating the co-citation method, factor analysis, and the networking visualization technique. The findings of this study provide a platform for scholarly discussion of the dissemination and research trends within the current ETiSE literature.     

远程多媒体学习软件教学设计模式初探

在远程学习条件下，教学者是以媒体技术作为传播手段与学习者进行交互的，在现代远程开放教育中更是以多媒体计算机作为主要的传输手段，学习者所处学习环境与课堂环境有很大不同。相应地，远程多媒体学习软件，其教学设计也与课堂教学条件下的多媒体教学软件的教学设计存在着明显差别。本文结合现代远程开放学习的特点，提出了一个远程多媒体学习软件的教学设计模式。
