Some new concepts such as private permission, public permission and special permission are introduced, based on the RRA97 model. Some new role-role inheriting forms such as normal inheritance, private inheritance, public inheritance and special-without inheritance are defined. Based on the ideas mentioned, the new role hierarchy model is formulated. It is easier and more comprehensible to describe role-role relationships through the new model than through the traditional ones. The new model is closer to the real world and its mechanism is more powerful. Particularly it is more suitable when used in large-scale role hierarchies.展开更多

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.展开更多
