基于势函数的厂商演化机制分析

供应链系统中，企业能力的差异导致了在供应链中的分工的不同，各种因素的合力促使企业在系统中的演化行为，我们称这种动力因素为厂商势。企业的能力、信息环境和契约环境等因素共同决定了厂商势的水平，当其中任一因素发生变化时，厂商势相应也将发生变化，其状态也相应产生演化过程。供应链系统中的企业的演化机理表明，企业演化过程中遵循从高势水平向低势水平变迁的一般规律，对供应链运作管理提供了一个新的视角。

Maximum likelihood and optimum location of observation sites in geodetic and spatial surveying

In geodetic and spatial surveying, accurate statistical es-timates of the Cartesian coordinates of a stationary target depend, in general, on such factors as target position, number and type of instruments, their location, their accuracy, and their mix. Direct measurements are assumed to be made in elevation, azimuth, and range with errors independently and normally distributed. For a mix of instruments, theoretical arguments are established using maximum likelihood estimation to determine the optimal siting of the instruments which minimizes (GDOP)² or the square of the geo-metric dilution of precision = sum of the variances of the estimates in the three orthogonal directions.     

苏台经贸合作的内外因素探析

江苏与台湾经贸合作20余年来,两地的经济联系与产业合作日益密切。自2002年之后,台商在江苏的直接投资一直遥遥领先于在其它省份的投资,两地的贸易份额逐步扩大。苏台经贸合作发展的内在原因在于台资企业自身的发展转型,江苏良好的投资环境以及与台湾产业的优势互补;外在因素在于大陆经济的高速增长,台湾政局的乱象以及国际经济的波动等。     

Headquarter Services in the Global Integration of Production

This study examines knowledge management within multinational enterprises (MNEs) by analyzing whether greater interdependence of production between U.S. parent firms and their foreign subsidiaries increases the provision of headquarter (HQ) services from the home country. The findings suggest that U.S. parents provide more assistance to their foreign subsidiaries that are linked in a global value chain than to those that are not involved in production sharing. This study builds on the earlier studies of the relationship between intra-MNE product flows and knowledge flows in multiple ways. First, it separately examines the relationship for high-tech and low-tech manufacturing industries, and finds that knowledge services from HQ that could be combined with knowledge of the subsidiary, such as R&D services, are primarily associated with production sharing with subsidiaries in high-tech manufacturing industries, which are assumed to be more technologically capable. Likewise, it finds that knowledge services from HQ that might be considered to be more passively received from the parent, such as industrial-type maintenance and design, are primarily associated with subsidiaries in low-tech manufacturing industries, which are assumed to be less technologically capable. Second, this study is the first one, to our knowledge, that gauges intra-firm knowledge flows using dollar-denominated measures of HQ services provided by parents to their subsidiaries.     

"四结合教学法"是适应高校教改新形势的教学方式

四结合教学法集多种教学形式于一体,使之有机结合,优势互补.学生在听懂重点、难点的基础上,通过讨论进行消化,通过实验加以巩固,再通过自学掌握大纲要求的其余知识点.这种教学法使学生的主体地位得以真正体现,教师的主导作用得以充分发挥,在学时少、内容多的教学及合班课教学中的教学效果为传统的灌输式教学法所无法比拟.     

知识经济与软件商品

知识经济时代的到来 ,使凝结在社会财富中的科学技术含量日益增加 ,软件随之成为独立的存在 ,并已走向商品化。软件的无形属性 ,不像硬件那样容易触摸 ,所以常常使人忽视其存在 ,形成若干观念误区。软件的总体数量超过硬件 ,是人类历史的进步 ,标志着社会生产力进入了崭新的阶段。文章对知识经济时代的软件商品做了全面考察。当前的重要任务就是从简单的粗放劳动解放出来 ,走向高效细腻的智力劳动 ,知识经济时代也就是软件商品时代

How do new members affect the relationship between principal investigator’s network position and academic output of granted funds?

The paper focuses on how to improve academic output of a granted fund when the adding of new members changes principal investigator’s network position. This objective is refined by exploring how new members affect the relationship between principal investigator’s network position and the academic output of granted funds, and whether this effect is similar in high-output and low-output collaboration networks. New members are divided into two groups, namely, international collaboration and inbound mobility. Using negative binomial regression on research funds supported by the National Natural Science Foundation of China, the results indicate that new members indeed have moderating effects on the relationship between principal investigator’s network position and the academic output of granted funds. Moreover, we find that this moderating effect in high-output collaboration networks is larger than that in low-output collaboration networks. Our findings provide practical implications for the decision makers to design funding planning and for the principal investigators to improve academic output.
