十年来我国义务教育均衡发展理念的六大转向

从2001年义务教育均衡发展理念的提出到现在,推进义务教育均衡发展的实践已走过了10多年的时间,在这10多年间我国义务教育均衡发展理念实现了六大转向：即从基础型均衡走向优质型均衡;从均等化均衡走向差异化均衡;从外延式均衡走向内涵式均衡;从意向性均衡走向标准性均衡;从依赖型均衡走向自主型均衡;从效率式均衡走向公平式均衡。     

台风结构的非对称性对台风运动的影响

本文分析了台风中心附近涡度局地变化■／■t的非对称性对台风加（减）速运动的影响结果表明，突然加速的台风，其前方和后方的■／■t分别为较大的正值和较小的负值；而突然减速的台风，其■／■t的分布则正相反此外，设计了一个综合考虑引导气流、涡旋结构以及涡度变化等因子作用的台风运动的预测方案。

Steering Dynamics in Complex Education Systems. An Agenda for Empirical Research

Many policy systems and education systems have grown more complex in the last three decades. Power has moved away from central governments in different directions: upwards towards international organisations, sideways towards private institutions and non‐governmental organisations and downwards towards local governments and public enterprises such as schools. Where once we had central government, we now have governance, which can be defined as the processes of establishing priorities, formulating and implementing policies, and being accountable in complex networks with many different actors. Steering in such complex education systems emerges from the activities, tasks and responsibilities of state and non‐state actors, operating at different levels and from different positions and often has un‐deliberate, un‐intentional and un‐foreseen consequences. There are many conceptual models that encapsulate this complexity, but this article suggests that there is a real need for empirical research. Without empirical research it remains unknown whether and how steering in complex networks works out in practice, what are its effects and for whom. Moreover, it is only through empirical research that we can find out whether central government has become less dominant, or rather whether its appearance has changed and it has become less visible, but not necessarily less influential. Foucault's governmentality perspective is a useful notion on which to build such a framework for empirical research which allows for a careful study of the interactions that signify steering. Inspired by Foucault, this article develops a trilogy of assumed conditions for steering to take effect in modern societies. Following this reasoning, ‘something' first needs to be made thinkable, calculable and practicable by different actors for steering to occur. This trilogy is a promising starting point for empirical research into very specific phenomena which can help us to understand how steering in complex education systems works.     

试论维特根斯坦语言哲学的转向

维特根斯坦是西方哲学史上一位非常独特的哲学家,他的独特之处在于他终其一生创造出了前后两种看似迥然不同甚至是相互对立的语言哲学理论。前期图像论认为表达世界的语言是一种实在的图像。这种图像的实质是人的思想对世界的反映。而后期语言游戏说否定了语言、世界、图像的一一对应的关系,认为语言是一种游戏,其意义在于使用。维特根斯坦语言学转向实质上是非本质主义的转向,其根本原因在于其前期图像论存在缺陷。尽管如此,前后期语言哲学实际上仍然有着千丝万缕的联系。     

基于AMESim的液压助力转向系统仿真研究

介绍了液压助力转向系统的基本组成和工作原理,为解决传递函数法在液压助力转向系统(HPS)仿真建模中的局限性,运用仿真软件AMESim建立了机液耦合的仿真模型。仿真分析了HPS系统中扭杆刚度、液压缸活塞直径、系统供油量三者对齿条位移动态响应的影响。结果表明:减小扭杆刚度对系统的动态响应影响不大,而增大液压缸活塞直径和系统供油量对其影响较大。仿真结果为HPS系统的设计和优化提供了理论依据。
