Fuzzy role-based access control

RBAC (Role-Based Access Control) is a widely used access control model, which reduces the maintenance cost of classical identity-based access control. However, despite the benefits of RBAC, there are environments in which RBAC can hardly be applied. We present FRBAC (Fuzzy Role-Based Access Control), a generalization of RBAC through fuzzy relations that extends the applicability of RBAC to environments where authorization-related information is vague. Moreover, FRBAC deals with environments where the actions that can be executed over the resources have a fractional meaning, as data lying in databases and risk-based access control. © 2011 Elsevier B.V.

How Asian Should Asian Law Be? – An Outsider’s View

Is there an Asian identity of Asian law, comparable to European identity and therefore similarly useful as a justification for unification projects? If so, what does it look like? And if so, does this make Asia more like Europe, or less so? Or is this question itself already a mere European projection? This chapter tries to address such questions. In particular, I look at a concrete project of Asian law unification—the Principles of Asian Comparative Law—and connect discussions about its Asian identity with four concepts of Asia. The first such concept is a European idea of Asia and Asian law, which defines a presumably homogeneous Asia on the basis of its level of difference from Europe. The next three concepts are concepts that emerged from Asian debates. Two off them explicitly invoke leadership of one country. A sinocentric concept of Asian law attempts to reinvigorate concepts from the time of Chinese dominance of East Asia prior to colonization. A Japanese concept of Pan-Asian law by contrast is built on Japanese modernization, which in turn was influenced by Europe. Finally, the idea of Asian values attempts to avoid leadership by any one country in favor of a truly Asian identity. None of these three chapters can fully avoid the central problems of the European projection: they are all defined by their relation to the West, and all of them invoke a relative degree of homogeneity as basis for identity. I close, therefore, with an alternative concept of Asia “as method” that attempts to overcome these two shortcomings and may offer a more promising path towards an idea of Asian law

The impact of information quality on information research

This contribution analyses the impact of information quality on research. It presents a theoretical discussion of the concept 'information quality' and shows that good information quality entails good research. The discussion is relevant for both researchers and research users, because it shows that information quality is a critical determinant of research success, as measured by the creation of new knowledge. Thus, information quality fundamentally impacts research. Reasons for the existence of low quality information as well as proposed solutions to this problem are provided in the paper
