Expert group formation using facility location analysis

In this paper, we propose an optimization framework to retrieve an optimal group of experts to perform a multi-aspect task. While a diverse set of skills are needed to perform a multi-aspect task, the group of assigned experts should be able to collectively cover all these required skills. We consider three types of multi-aspect expert group formation problems and propose a unified framework to solve these problems accurately and efficiently. The first problem is concerned with finding the top k experts for a given task, while the required skills of the task are implicitly described. In the second problem, the required skills of the tasks are explicitly described using some keywords but each expert has a limited capacity to perform these tasks and therefore should be assigned to a limited number of them. Finally, the third problem is the combination of the first and the second problems. Our proposed optimization framework is based on the Facility Location Analysis which is a well known branch of the Operation Research. In our experiments, we compare the accuracy and efficiency of the proposed framework with the state-of-the-art approaches for the group formation problems. The experiment results show the effectiveness of our proposed methods in comparison with state-of-the-art approaches.     

承接产业转移与河南汽车产业升级研究

在分析河南汽车产业发展优势及问题的基础上,认为在承接产业转移背景下实现全球、地方联结与互动,转移企业地方化结网与本地企业技术学习,转移领先企业国内价值链构建与技术权力作用,构建区域创新环境与打开区位机会窗口等共同促进了河南汽车产业升级。大力推动汽车行业兼并重组、提高省内汽车和零部件制造企业之间配套率、培育和引入具有较强辐射带动能力的领先企业、不断提升自主创新能力应成为河南汽车产业的升级方向。     

时变条件下的危险品运输与应急救援双层规划研究

危险品运输因其发生事故的后果危害性大,因此对于如何选择一条既能保证运输安全又能满足运输需求的最优路径已经成为一项非常重要的研究内容。在总结前人研究的基础上,提出在时变条件下考虑应急救援的危险品运输路径双层规划模型,同时考虑运输时间限制与出发等待时间弹性以及运输网络中的应急救援能力。通过算法求解与应用算例,结果表明:双层规划更好地描述了企业和政府之间的博弈决策,而且将应急救援因素作为路径选择的重要依据有利于寻求更符合实际的最优路径。     

关税减让对中国进口日韩汽车贸易影响的实证研究

文章选取2001-2010年中国进口日韩汽车贸易为样本面板数据,以比较优势理论和要素禀赋理论为基础,通过构建关税减让进口贸易模型,尝试分析关税减让对我国汽车进出口贸易的影响,旨在为当前的中日韩FTA贸易谈判提供参考依据。研究发现：(1)从PCT职务申请看,日本对中国继续保持绝对技术优势,而韩国的技术优势在逐渐缩小,而且中国在离合器、制动系统等零部件领域有反超的趋势;(2)进口关税的降低大大推动了日韩汽车的对华出口贸易,同时不可避免会对国内汽车造成一定冲击。(3)随着我国经济的持续增长,国内汽车消费需求急速增加,我国汽车关税进一步降低带来的影响甚至可能会超过入世时的影响。不仅如此,日本和韩国的汽车进口关税远低于中国,加之我国本身技术创新能力不高,汽车进口关税的减让应该以日韩对我国农产品关税的大幅下降,才能实现双赢。

Neuro‐linguistic programming and altered states: encouraging preparation for learning in the classroom for students with special educational needs

In seeking to identify the processes associated with the immediate engagement of learning for students with mild special educational needs, this study examined the responses of an extraction group (n = 7) of 11‐ to 13‐year‐old students who participated in a number of lessons in which the opening episode involved the use of visualisation techniques and language associated with representational systems as identified within neuro‐linguistic programming (NLP). Students endeavoured to alter their negative state to a positive state via this intervention. The study, by Voldis Kudliskis of South Dartmoor Community College, was of a naturalistic research design, and the students' experiences were explored by means of formal interviews, semi‐structured interviews, questionnaires and observations. The implications for altering state through techniques associated with NLP are described and evaluated in terms of student comments. The case is made for the process of altering state as a strategy to empower students to engage with their learning from the outset of the lesson.     

以科学管理导引文化自觉——北京市小学规范化工程的目的与方法

本文对北京市2007年开始的小学规范化建设工程设计进行分析，指出小学规范化建设的目的是提高质量，基线调查、合理规划和增值评价是提高质量的必然要求。基线调查为合理规划、增值评价积累了数据，奠定了基础，增值评价可以为规划的实施情况进行科学评价，三个方法之间是相互联系的。
