我国能耗监测管理现状及未来发展趋势

适应节能形势发展的新变化,能耗监测的内涵也正在逐步延伸。实践表明,建立有效的能耗监测管控体系,对于提高能效、推进节能减排作用明显。近年来我国能耗监测管理得到了不同程度的改善,但在管理理念、制度安排、技术创新、资金支持等方面还存在着较多问题。利用信息技术,建立能耗在线实时监测管理体系,将成为未来能耗监测的发展目标。适应这种发展要求,我国需要在计量设备基础管理、能耗监测考核制度、监测机构设置和人员培训、资金渠道等方面进行不断创新。     

Does CEO duality constrain board independence? Some evidence from audit pricing

This study examines whether CEO duality affects the association between board independence and demand for higher quality audits, proxied by audit fee. The findings show that there is a positive association between board independence and audit fees. This result is consistent with findings of Carcello et al. (2002) that more independent boards demand higher audit quality and effort. However, this positive association is only present in firms without CEO duality, thus suggesting that CEO duality constrains board independence. The results support recommendations against CEO duality by showing that dominant CEOs may compromise the independence of their board of directors. Additionally, evidence is provided that board size (the number of directors on the board) is positively associated with audit fee pricing. This is consistent with prior studies that indicate that larger board sizes are associated with inefficiency and negative firm performance.

Using templates and linguistic patterns to define process performance indicators

Process performance management (PPM) aims at measuring, monitoring and analysing the performance of business processes (BPs), in order to check the achievement of strategic and operational goals and to support decision-making for their optimisation. PPM is based on process performance indicators (PPIs), so having an appropriate definition of them is crucial. One of the main problems of PPIs definition is to express them in an unambiguous, complete, understandable, traceable and verifiable manner. In practice, PPIs are defined informally – usually in ad hoc, natural language, with its well-known problems – or they are defined from an implementation perspective, hardly understandable to non-technical people. In order to solve this problem, in this article we propose a novel approach to improve the definition of PPIs using templates and linguistic patterns. This approach promotes reuse, reduces both ambiguities and missing information, is understandable to all stakeholders and maintains traceability with the process model. Furthermore, it enables the automated processing of PPI definitions by its straightforward translation into the PPINOT metamodel, allowing the gathering of the required information for their computation as well as the analysis of the relationships between them and with BP elements.     

Evaluating Board Roles Performance in Adopting Corporate Social Responsibility （CSR） Practices

The purpose of this paper is to evaluate the board roles that make a board effective in the performance of adopting corporate social responsibility （CSR） practices. This paper examines directors＇ perceptions of the three main roles： monitoring, service, and strategic, which provide tools for critically understanding how the board adds the value in moving the organization towards more CSR practices. The stakeholder theory is used to distinguish the influence of the three main roles on the adoption of CSR practices. Primary data were collected for this research by conducting structured questionnaires with a sample of 461 directors from Saudi listed companies for study purpose. The results show that an appropriate mix of directors＇ roles and the development of sound board monitoring and service roles are the most crucial determinants of CSR adoption in Saudi listed companies. As the extant corporate governance and CSR literatures do not provide a clear perspective with contradictory outcomes about board roles in influencing CSR practices, the originality of this research is its contribution by evaluating the directors＇ perceptions of developing a direct relationship between the board roles and the adoption of CSR practices. Furthermore, the use of the stakeholder theory provides additional insights into identifying the most influential board role factors enhancing stakeholders＇ expectations of CSR practices.     

Monitoring as a partially observable decision problem

Monitoring is an important and costly activity in resource management problems such as containing invasive species, protecting endangered species, preventing soil erosion, and regulating contracts for environmental services. Recent studies have viewed optimal monitoring as a Partially Observable Markov Decision Process (POMDP), which provides a framework for sequential decision making under stochastic resource dynamics and uncertainty about the resource state. We present an overview of the POMDP framework and its applications to resource monitoring. We discuss the concept of the information content provided by monitoring systems and illustrate how information content affects optimal monitoring strategies. Finally, we demonstrate how the timing of monitoring in relation to resource treatment and transition can have substantial effects on optimal monitoring strategies.
