DSS research and practice in perspective

The aim of this paper is to assess the state-of-the-art in the Decision Support Systems (DSS) field from both a research and a practice perspective. Three main dimensions of DSS research and practice are addressed: 1) supporting human decision-making processes, 2) integrating DSS into the organizational context, and 3) identifying new application domains. The related analysis and discussion provides a better understanding of past developments in the DSS field and insights into future evolution patterns.

Does positive affect influence the effective usage of a Decision Support System?

This study examines the impact of positive mood on the effective usage of a Decision Support System (DSS). Using current cognitive theories, a theoretical argument about DSS usage is developed. This argument is then investigated via a lab experiment. The results of the lab experiment show that decision makers in positive mood used a greater number of informational cues provided by the DSS and made more accurate judgments.

Effectiveness of Security Control Risk Assessments for Enterprises: Assess on the Business Perspective of Security Risks

ABSTRACT

Today's businesses being IT enabled, the complexity of risks affecting the business has increased manifold and the need to gauge the Information Technology risks acting on the business operations has become paramount. The business managers who run business operations need to operate securely and seamlessly leveraging Information Technology and ability to recover and resume the business without any loss of confidentiality, integrity and availability of business information/data in any event of a security incident.

There is a need to quantify the impact of the IT security risk on the critical business processes, and provide the business-level insight at the management level. It is critical to classifying the Risk Ratings as per the impact on the business operations. This approach allows the organizations to understand and prioritize the security risk management activities that make the most sense for their organization to secure the business operations instead of trying to protect against every conceivable threat.     

高性能计算中处理器功耗特征的评测与分析

高性能计算系统的系统结构和应用模式与单机系统或商用机群服务器系统都有很大的不同,掌握功耗特征是提高能效的前提。本文将支撑功耗管理的低功耗技术分为动态资源休眠和动态速率调节两类,并就处理器的这两类机制在高性能计算中的应用进行评测,验证了功耗管理在高性能计算中的有效性,量化分析了处理器功耗特征,指出了当前管理方案的不足及改进设想,对进一步能耗优化有重要的指导意义。
