农村中小企业融资:一个金融资源配置效率的分析框架

根据金融资源的性质,本文建立了一个金融资源配置效率的理论框架,说明金融资源配置的静态效率、动态效率以及金融效率可持续的社会经济基础,并解释了农村中小企业融资难的症结在于融资权约束。在此基础上,本文提出了农村中小企业融资的制度创新应从金融资源配置效率的持续性入手,发展新的金融组织和业务模式,改进金融资源配置的均衡点,形成金融资源配置与农村经济和社会发展的协调机制。     

动态特征下国有公路施工企业绩效管理研究

国有公路施工企业绩效管理受外部环境动态变化性、内部组织结构动态调整性、员工能力动态发展性等动态因素影响较大,绩效管理效果不佳,员工满意度低。建议国有公路施工企业从健全绩效管理保障体系,保证绩效管理公平、科学制定绩效计划,保证内容合理标准明确、规范日常绩效记录,合理设置考核周期、加强绩效沟通辅导,消除绩效管理障碍等四个方面着手,降低动态性因素带来的绩效管理不利影响,从而发挥出绩效管理应有的激励作用。

Towards a personalized task selection model with shared instructional control

Modern education emphasizes the need to flexibly personalize learning tasks to individual learners. This article discusses a personalized task-selection model with shared instructional control based on two current tendencies for the dynamic sequencing of learning tasks: (1) personalization by an instructional agent which makes sequencing decisions on the basis of learner’s expertise, and (2) personalization by the learner who is given control over – final – task selection. The model combines both trends in a model with shared instructional control. From all available learning tasks, an instructional agent selects a subset of tasks based on the learner’s performance scores and invested mental effort (i.e., system-control). Subsequently, this subset is presented to the learner who makes the final decision (i.e., learner control). A computer-assisted instructional program has been developed to put the model into practice and preliminary results are discussed. The model can be used to increase the efficiency and effectiveness of instruction and to make it more appealing by providing the learner an optimal level of control over task selection. This research project is funded by the Netherlands Organization for Scientific Research (NWO, The Hague, project No. 411-02-107-V).     

基于$\piup$演算的多agent系统建模与分析

Dynamic architecture of multi-agent systems (MAS) is important for critical systems. As the existing formal specifications of MAS cannot describe its dynamic architecture, a formal approach using $\piup$-calculus is presented, which is suited for the describing and analyzing of concurrent MAS with dynamic topology. $\piup$-calculus describes the belief-desire-intention (BDI) model that represents agent's mental states and provides many useful facilities to analyze MAS model such as deadlock, behavior equivalence, and model checking. To illustrate the favorable representation capability of $\piup$-calculus, an example of dynamic multi-agent systems in e-commerce is provided. Finally, by using an existing $\piup$-calculus supporting tool, MAS model and some key behaviors properties are analyzed and verified.     

文化差异与教育信息化可持续发展研究

<国家中长期教育改革和发展规划纲要(2010-2020年>明确提出要加快教育信息化进程,实现教育信息化可持续发展.从现实来看,文化成为新时期推进区域教育信息化事业可持续发展的一个重要变量,也成为探究教育信息化可持续发展的可能视角.本文基于霍夫斯泰德的文化差异指数模型,以"经济学人智库"发布的"数字化学习准备度"为教育信息化发展指标,研究区域教育信息化和文化差异之间的关系.研究者利用数据拟合探究了两者之间的相关性,发现区域教育信息化发展水平和文化变量密切相关,且系统推动文化变迁、建立文化映射可以助推教育信息化可持续发展,并据此提出一种文化推进教育信息化可持续发展的系统框架和动力机制.     

外显与内隐学习动态权衡的认知理据

近年来,外显学习和内隐学习的关系问题逐渐成为认知心理学家们研究的焦点。在二语习得研究领域,围绕国内外相关理论和实验研究结果,探讨外显和内隐学习的概念特征、区别和联系。外显学习和内隐学习虽然有着本质的不同,但存在某种程度的共性,二者是一种动态权衡的关系,在二语习得中具有重要的实践应用价值。     

英语专业写作教学中三级动态评价体系的构建

动态评价是在评价过程中通过评价者和学生的互动,尤其是在有经验的评价者的帮助下,探索和发现学生潜在发展能力的一系列评价方式的统称。将动态评价的理念引入英语专业写作教学评价中,努力构建一个英语专业写作教学的三级动态评价体系,可以在不忽视教师指导作用的前提下,充分发挥学生的认知主体作用,实现英语写作教学中的评价的互动性、评价的过程性以及评价的发展性,达到最终提高学生英语写作能力和自主学习能力的目的。
