The paper opted for an ordinary least square （OLS） cluster regression and followed by a stochastic frontier approach test as a robustness test. Findings of this study indicate that organizational forms of Islamic banks influence managerial expense preferences. A stochastic frontier approach test supports the initial findings and reveals that the average noninterest cost inefficiency of Islamic banks without Shari＇ah Boards is 23% compared to commercial banks. Islamic banks with Shari＇ah Boards are, on average, 28% less noninterest cost inefficient compared to Islamic banks without Shari＇ah Boards, and are on average, 16% less noninterest cost inefficient compared to commercial banks. Shari＇ah Supervisory Boards＇ positive implications for Islamic banks are independent of the expectations of the governing structure or ownership. Specifically when looking at Islamic banks with Shari＇ah Supervisory Boards, managerial propensity to engage in self-serving behavior is reduced. This paper fulfils an identified need to understand how the distinct nature of Islamic banks organizational forms and governance impact managerial behaviour.展开更多

In this paper, we clarify why existing closed world approaches, such as the CWA, the GCWA, the ECWA, circumscription, predicate completion and the PWA, fail to do so, and propose a new method. The method is an augmentation of both the ECWA and circumscrip- tion with the mechanism to discriminate implicitly expressed positive knowledge, negative knowledge and truly unknown knowledge.展开更多

文摘Through analyzing influence of various factors on spatial form of campus, the author proposed from the perspective of knowledge science that orientation and mode of knowledge activities play a decisive role in the spatial form evolution of campus, and then demonstrated the viewpoint by elaborating spatial form evolution history of campuses of different ages in different regions. On this basis, the future development trend of campus form in the information era was explored.
