论英语语篇分析与词义解读

语篇分析是刚发展起来的新兴研究领域。旨在从篇章、社会和心理诸多语言环境因素的角度来研究实际交际过程中意义连贯的语言整体。而传统语言学都是以音系、词汇或句法为研究单位,导致了英语初学者在对英语单词的一词多义或具体上下文中的特别意义的解读上几乎无从下手。英语学习者应站在语篇的高度,运用语篇分析的方法来解读英语单词,这不仅是重要的,也是可行的。

Parents and professionals working together: turning the rhetoric into reality

Parental involvement and participation, partnership with parents, and community‐focused development are important features of government initiatives such as the Sure Start project for children under four years of age and their families. A common feature of the rhetoric is ‘empowerment’ as a means of achieving this. This article describes the activity and development of the Parents Committee in one Sure Start programme and uses this to tease out different dimensions of empowerment. In particular, it highlights issues regarding developing empowerment and the dynamic tension between the growth of personal power and the changing symmetry of power relationships. A tentative model of the trajectory of developing empowerment is presented. This may raise challenges for professionals seeking to fulfill their professional role in a complex context and questions as to whether, or how, it might be possible to better prepare professionals for this dimension of their work.

Secondary School Students Learning From Reflections on the Rationale Behind Self-Made Errors: A Field Experiment

Thus far, it is unclear how students can learn most effectively from their own errors. In this study, reflections on the rationale behind self-made errors are assumed to enhance knowledge acquisition. In a field experiment with pre/post/follow-up design, the authors practiced fractions with 174 seventh- and eighth-grade students who were randomly assigned to one of two conditions: The students reflected on either the rationale behind their own errors or on the correct solution corresponding to their own errors. Students in the first condition group demonstrated a greater procedural knowledge at the posttest and at the follow-up test. Furthermore, at the follow-up test, these students demonstrated a higher conceptual knowledge. The implications for theory and school instruction are discussed.     

温度场中非线性弹性地基上矩形薄板的1/3次亚谐共振

为了研究温度场中非线性地基上矩形薄板受简谐激励的1/3次亚谐共振问题,应用弹性力学理论建立其动力学方程,应用Galerkin方法将其转化为非线性振动方程。利用非线性振动的多尺度分析方法求得系统1/3次亚谐共振的近似解,并进行数值计算。分析温度、地基系数、阻尼、几何参数、激励等对系统3次超谐共振的影响。得到了随参数变化响应曲线的变化规律。
