An Analysis of Foreign Language Learning Styles from the Cognitive Perspective

From the 1970s,learning styles began to enter the domain of foreign language learning researches.Foreign language learning style is often regarded as a significant factor attributing to individual differences among language learners.Nowadays,many researchers begin studying individual learners’characteristics and exploring how different learners interact with external factors from cognitive perspective.The field-independence/dependence construct became a focus.Based on previous studies,the paper is committed to analyzing the nature of FID learners.It is expected that this research can establish a well-grounded basis for following studies.     

关于格蕴涵代数

讨论了拟格蕴涵代数的基本性质,由此得到：拟格蕴涵代数X为格蕴涵代数当且仅当≤L与≤F一致等若干充要条件.这里,X（X,V,∧,`,→,0,1）为拟格蕴涵代数,≤L为格（X,∨,∧）上的自然偏序关系,≤F为由蕴涵算子→、诱导的偏序关系.     

Comparison study of harmonic imaging (HI) and fundamental imaging (FI) in fetal echocardiography

Objectives: To directly compare the quality of harmonic imaging (HI) and fundamental imaging (FI) in fetal echocardiography and to determine any differences in image quality between the two modalities. Methods: Fetal echocardiograms were performed with the use of FI and HI in 58 fetuses, image quality and visualization of left and right atria, left and right ventricles, mitral and tricuspid valves, aortic and pulmonary valves, left and right ventricular outflow tracts were evaluated and compared between FI and HI. Results: Mean HI scores were higher than mean FI scores (2.73±0.43 vs 2.16±0.69, P<0.001)for all the cardiovascular structures evaluated. Compared with FI, HI improved the image quality and visualization of fetal cardiac structures in subjects with both good (2.73±0.43 vs 2.88±0.32, P<0.001) and suboptimal (1.65±0.41 vs 2.58±0.47, P<0.001) echocardiographic windows. The interobserver correlation coefficient for the grading scores was 0.74 (P<0.001). Conclusions: harmonic imaging enhances and improves the image quality of fetal echocardiography; and has important potential role in cardiac imaging in the fetus.     

关于弱FI-代数和弱MV-代数的一点注记

证明了弱FI－代数与BCI－代数是互相等价的。因而，可以充分利用BCI－代数的理论来研究弱FI－代数，此外，还证明弱MV－代数与MV－代数本质上也是同一概念。

场认知风格与高职生英语阅读的相关性研究

场独立／场依存认知风格是指人在知觉活动中表现出的对外界参照所依赖的不同程度。场认知风格对英语阅读有着重要的影响。大多数高职学生具有场依存性倾向,而场独立型学生的英语阅读能力好于场依存型学生。通过有意识地培养和转换这两种认知风格,采取匹配的教学策略,对提高高职生的英语阅读成绩具有一定的帮助。     

认知风格、学习策略与英语学习成绩的关系研究

认知风格、学习策略与外语学习密切相关。本研究以非英语专业本科学生为对象,通过调查发现,分属场独立-场依存认知风格的学习者在学习策略的选择方面没有显著差异,不同认知风格与学习策略的使用频率对英语学习成绩的交互效应不明显,英语学习成绩与整体学习策略与三类分策略,即认知、元认知、补偿策略有显著相关。     

面向MICK-4FI模式的资源分类研究

针对资源分类问题,首先分析经济发展特征,并据此确立了资源分类依据,进而将资源分类为物质、信息、资金和知识(MICK)四大类。在澄清资源定义中易混淆部分后,基于新资源分类研究成果构建了MICK-4FI(四流集成)资源运营模式。本模式在操作层面以资源为驱动因素,分析企业如何能快速集成内外部资源迅速获得竞争优势。
