跨国公司在华并购的技术溢出效应对我国产业竞争力的影响

20世纪90年代以来,世界上掀起风起云涌的跨国并购热潮,跨国并购成为我国对外直接投资的主要方式,其技术溢出效应对我国产业竞争力产生积极和消极影响.本文首先对跨国并购,技术溢出效应和产业竞争力进行内涵界定;然后阐述了跨国公司在华并购技术溢出效应的制约因素.在此基础上,提出跨国公司在华并购技术溢出效应具有两面性.     

Current status,enablers ＆ barriers of implementing cellular manufacturing system in Indian industries

The cellular manufacturing （CM） has been proved as a well-known manufacturing strategy that helps to improve manufacturing efficiency and productivity by utilizing the philosophy of group technology. Large num- ber of papers has been published in the area of design issues of CM system. Unfortunately, the issues related to acceptability of CM in Indian industries are typically not examined rigorously as technical issues. This paper pre- sents the results of a survey carded out to find the status, enabler and barrier of implementing CM system in Indian industries.     

中国上市物流企业成本效率动态分析——基于Cost Malmquist指数

通过对2006~2013年48家上市物流企业投入要素价格变化的量化处理,建立上市物流企业Cost Malmquist(CM)指数,扩展基于成本函数的Malmquist指数,将其变动进一步分解为技术效率变动、技术进步变动、配置效率变动以及价格因素变动4个部分,并与传统的投入Malmquist(IM)指数进行对比。研究表明:48家上市物流企业的CM指数表现了比IM指数更为明显的生产率退步,其中引起CM指数退步的因素中价格波动要大于配置效率变动,这是IM指数无法测度出来的。     

CM模式的项目管理研究

我国优秀男子跳远运动员助跑最后两步身体重心高度变化特征

采用文献资料、高速摄影、影片解析、数理统计及对比分析的方法,对我国部分优秀男子跳远运动员助跑最后两步身体重心高度变化进行研究,认为我国男子跳远运动员助跑最后两步身体重心高度变化具有不合理性,并提出合理建议,为今后我国男子跳远训练提供参考和借鉴.     

关于费玛曲线xN+yN=1的K2群的一些注记

首先简单介绍了对于有理数域上光滑射影曲线的Beilinson猜想,然后应用椭圆簇的知识指出了存在于费玛曲线K₂群中的一个元素, 最后在费玛曲线X₃这个特殊情形下,将其L-函数与Eisenstein-Kronecker-Lerch级数明确地联系起来,从而验证了其L-函数满足的函数方程,以及它能在复平面上解析延拓的事实.

Child maltreatment deaths in the U.S. National Child Death Review Case Reporting System

Comprehensive reviews of child death are increasingly conducted throughout the world, although limited information is available about how this information is systematically used to prevent future deaths. To address this need, we used cases from 2005 to 2009 in the U.S. National Child Death Review Case Reporting System to compare child and offender characteristics and to link that information with actions taken or recommended by review teams. Child, caretaker, and offender characteristics, and outcomes were compared to team responses, and findings were compared to published case series. Among 49,947 child deaths from 23 states entered into the Case Reporting System during the study period, there were 2,285 cases in which child maltreatment caused or contributed to fatality. Over one-half had neglect identified as the maltreatment, and 30% had abusive head trauma. Several child and offender characteristics were associated with specific maltreatment subtypes, and child death review teams recommended and/or planned several activities in their communities. Case characteristics were similar to those published in other reports of child maltreatment deaths. Teams implemented 109 actions or strategies after their review, and we found that aggregating information from child death reviews offers important insights into understanding and preventing future deaths. The National Child Death Review Case Reporting System contains information about a large population which confirms and expands our knowledge about child maltreatment deaths and which can be used by communities for future action.
