如何认识市场经济中企业与政府的关系

随着国民经济的迅速发展,我国经济出现了日趋繁荣的景象,但是,也暴露出一些尖锐的问题。如机构庞大、人员臃肿、政企不分等问题,这些问题直接阻碍了改革的深入和经济的发展。本文试从市场经济中政府与企业的角色定位出发来阐述企业与政府的关系。

Role mechanisms in collaborative systems

Computer-supported cooperative work (CSCW) systems are computer-based tools that support collaborative activities. They should meet the requirements of normal collaborative efforts among people. They should not only support virtual face-to-face collaboration among people at a distance, but also improve face-to-face collaboration by providing more mechanisms to overcome the drawbacks of face-to-face collaboration among people. Therefore, introducing roles into CSCW systems is extremely important. By roles, one can avoid users of CSCW systems being overwhelmed by too much irrelevant information. One of the major problems in current CSCW systems is determining how to define and specify roles clearly and rigorously while maintaining the flexibility for collaboration. Many traditional CSCW systems based on roles have lost their flexibility after introducing roles because they can only provide static role mechanisms based on intuitive role concepts. There are no flexible mechanisms for role tuning, changing and transitions because there is not a special mechanism to express a role. This paper reviews the applications of roles in traditional collaborative systems, clarifies the general meanings of roles, discusses the functions of roles in collaboration, and suggests a role mechanism and a group of principles to support collaboration based on roles. This paper concludes that roles need more comprehensive research and will be applied widely in different areas.

基于航空器位置-速度矢量关系的短期冲突检测算法

为了解决高密度飞行环境下航空器对的短期冲突虚警问题,研究了航空器当前位置和速度矢量的相互关系,证明了只有位置差与速度差矢量内积小于零的航迹对才具有潜在冲突,并根据安全飞行间隔规定,采用线性预测方法对其进行冲突有效性确认,实现快速有效的短期冲突检测.通过模拟试验下的监视雷达数据,验证了本文算法的有效和准确性,相对于其他算法,本算法快速准确地实现了高密度飞行情况下潜在短期冲突航空器对的检测,并解决了当航空器背向飞行时不再进行告警的问题,减少了地面管制人员的工作量.

Fault coverage of Constrained Random Test Selection for access control: A formal analysis

A probabilistic model of fault coverage is presented. This model is used to analyze the variation in the fault detection effectiveness associated with the use of two test selection strategies: heuristics-based and Constrained Random Test Selection (CRTS). These strategies arise in the context of conformance test suite generation for Role Based Access Control (RBAC) systems. The proposed model utilizes coverage matrix based approach for fault coverage analysis. First, two boundary instances of fault distribution are considered and then generalized. The fault coverages of the test suites generated using the heuristics-based and the CRTS strategies, applied to a sample RBAC policy, are then compared through simulation. Finally the simulation results are correlated with a case study.
