在构件的多个实现间动态选择的算法*

为了提高构件在处理多种类型请求时的效率,构件可以有多个不同的内部实现,每一个实现都是为一种特定类型的请求而优化的。提出了一种在构件的多个实现间动态选择的算法,算法尽可能地为每一种类型的请求挑选最优的实现,同时又尽量避免在不同的实现之间进行切换,从而使构件在处理一个请求序列时所花费的总开销尽可能少。

Managing projects with distributed and embedded knowledge through interactions

In project-based industries studies show difficulties in extracting, distributing and applying embedded and practice knowledge across structural and organisational boundaries. We focus on interorganisational projects consisting of distributed and embedded knowledge. Interaction becomes important in order to cooperate and share interorganisational and distributed knowledge. The aim of the research is to explore how sharing and generating practice based and distributed knowledge occurs through interaction in interorganisational projects and how this is managed. The study focuses on the design phase and relates traditional design practices to concurrent design practices. In the study we observed six cases of design meetings in the construction and oil and gas industry and performed 31 interviews. The paper contributes with the following: (1) understanding and visualisation of interaction patterns, (2) insight in use of various forms of interaction, and (3) ways of managing distributed and embedded knowledge through interaction.

Managing the five tensions of IT-enabled decision support in turbulent and high-velocity environments

This chapter examines issues concerned with supporting managers and organizations with information and communication technologies as they decide and act in turbulent and high-velocity environments. In particular, the chapter identifies five key tensions in this context: (1) the tension between the need for quick decisions and the need for analytical decision processes; (2) the tension involving managerial need for action and the need for the safest execution of decisions that may be bold and risky; (3) the tension around empowering middle managers and management teams at various organizational levels in the midst of powerful and impatient top executives; (4) the tension between programmed, quick-action learning loops and the increased requirement for emergence and improvisation; and (5) the tension between expending effort to eliminate the digital divide with other organizations versus finding expedient ways to communicate through heterogeneous digital infrastructures. Each of the tensions, and how it can be managed, is illustrated through a case example. The chapter ends by suggesting that the management of these critical tensions needs to be fused into the day-to-day fabric of management practices for decision support processes. This article is part of the “Handbook on Decision Support Systems” edited by Frada Burstein and Clyde W. Holsapple (2008) Springer.     

The role of monitoring and shirking in information systems project management

Agency theory offers a foundation for explaining the impact of project monitoring on project success. This study applied agency theory to survey 428 information systems project managers concerning their project monitoring, shirking by systems developers, and project success. Greater project monitoring via planning and meetings predicted less shirking, while greater monitoring via responsibilities and comparison did not. Less shirking via poor focus predicted increased project success, while less shirking via loafing did not. These findings have implications for project managers and project management researchers.     

反思我国“市管县”体制

８０年代以来，我国大规模推行市管县体制，文章分析了市管县体制的作用与本质，认为在这种体制下，中心城市作用未能很好发挥，市县之间普遍存在利益冲突，最后指出市管县体制是我国新旧体制交替阶段的一种过渡形式，社会主义市场经济体制的建立将使其失去存在的基础。
