We introduce a multimodal logic for order of magnitude reasoning which considers a new logic-based alternative to the notion of closeness, we provide an axiom system and prove its soundness and completeness.

OBJECTIVES: To report the outcome of applications to 43 research ethics committees. SETTING: Four regional health authorities in England. FINDINGS: The research ethics committees varied considerably in their practices. The time lapse until notification of the outcome of the approval ranged from just under one week to 23 weeks with a mean of 8.6 weeks. Four research ethics committees failed to notify the research team of an outcome of their request for approval. CONCLUSION: A national research ethics committee is needed (...) to review national and multi-location research studies in the light of the fragmented and variable practice of local research ethics committees.

This paper offers a new approach to the philosophical foundations of information systems through feminist philosophy and, in particular, feminist epistemology. This can be used to expose the universalizing tendency of many information systems and to show the importance of using real-life complex examples rather than the simplified examples often favored by philosophers. Within traditional epistemology and its relation to IS, subjectivity, the propositional/skills distinction and epistemic hierarchies are subject to arguments from feminist epistemology. With respect to the emerging critical (...) school of IS, feminist epistemology, and within that, feminist standpoint theory, are used to examine the complexities of the positivist/anti-positivist position and the related concept of emancipation. In addition, it is argued that the liberal version of emancipation encapsulated in such systems may have an effect opposite to that of emancipation These issues are illustrated in an existing expert systems project.
