我国企业开展流程再造应从工作研究开始

由于管理基础工作薄弱，我国很多企业流程再造的努力未获成功。基于企业流程再造与工作研究之间的对比分析，文章提出了运用工作研究领域内的有关理论、经验、方法和工具来帮助我国企业开展流程再造。     

基于移动Agent技术的QoS保障机制

介绍了移动Agent的基本特性。移动Agent可在异构的网络各个节点间自由地移动,它能感知网络的状态,监控系统并与其他Agent进行交互。IETF的IS模型采用了RSVP(ResourcereSerVationProtocol)协议对系统资源进行预留,从而达到一定程度上保障所需QoS的目的。QoS保障机制将移动agent技术与RSVP协议结合起来,通过资源预留和agent动态移动的实现可以达到更好地改善QoS的目的。     

Review of Counseling and psychotherapy of work dysfunctions.

Reviews the book, Counseling and psychotherapy of work dysfunctions by Rodney L. Lowman (see record 1993-98413-000). Dr. Lowman's book on work dysfunctions serves as a seminal product for further understanding a much-neglected component of the lives of the many men and women who seek psychological assistance in working through issues around their employment. The book conveys in a well-written, sometimes humorous, style that "work is a natural part of living, and the issues it raises are important parts of character." The overall impression is that of a well-thought-out and most readable book. There is no doubt in this reviewer's mind that it will become essential reading for psychologists, social workers, family therapists, and graduate students who are becoming increasingly involved in this field of study. What this reviewer found very helpful was the clarity of presentation of the assessment techniques as well as the amply illustrated intervention modules that may be utilized. To this reviewer, there is no doubt that this is one area for psychologists' contributions in the future--the work area. Lowman's book gives us basic material from which to continue to build our profession in a new and exciting direction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

基于移动端多天线系统的无线衰落信道模型

根据当前无线移动通信对多天线移动接收端性能仿真的要求，讨论并建立了适于空时信号处理的移动端矢量信道模型。通过分析无线移动信道特点。研究了影响接收信号幅度相位的诸多因素，建立了相应的数学模型。并对随机参数选取进行了探讨。其中考虑到移动端接收信号到达角扩散的特点，采用GBSB椭圆模型产生了适于移动端接收信号仿真的随机角度，改进了一种瑞利衰落生成算法。最后信道的数值仿真结果符合理论和经验。同时，通过TD-SCDMA系统链路级仿真，也证明了该信道模型的有效性。

The Content Driven Mobile Internet

The development of future mobile networks will be driven, in large part, by content and web based services. In this paper, we examine several performance, scalability and architectural challenges faced by future mobile web applications and how advanced mobile content delivery techniques can address these challenges. We review existing content delivery using a taxonomy that consists of three categories: network scaling, end system acceleration, and content and protocol optimization. While wireline content delivery focuses on network and server scalability, mobile content delivery will likely benefit most from optimizing radio link usage. We also present our ongoing work in this area, which extends the functionality of edge caching to the terminal, uses user interest correlation information to maintain low terminal power consumption and adds a new dimension to radio resource management. This revised version was published online in August 2006 with corrections to the Cover Date.     

Ubiquitous Information Services with JAIN Platform

To provide responsive information services in a ubiquitous computing environment, service software and system development are indispensable. A component-based ubiquitous information system with a JAIN (Java APIs for Integrated Networks) platform to achieve seamless transmissions and reach-everywhere communications was designed in our research. In this development, numerous ubiquitous service modules were identified: location management, roaming, mobile IP and WAP networking. These component-based network modules were constructed using a component composition language with component specification and interface definition, running on top of a distributed service architecture using a JAIN platform to distribute the ubiquitous information services to mobile users. Two applications, Wireless-Application-Protocol (WAP) Mail and Video-on-Demand (VoD) services, show that the JAIN-like platform with the developed networking components effectively fills the gap for application developers between mobile appliances and various kinds of ubiquitous information services.
