Our work on this Special Issue began with a showcase symposium on the philosophical foundations of knowledge management (KM) at the AoM 2004 Meeting and was continued through KM tracks at the EURAM 2005 and EGOS 2005 Conferences. Our hope was to corral the variety of approaches in the KM literature and expose solid underpinnings against which the field's development might be gauged. We were unclear whether these would be axiomatic principles that defined the field or a set of professionally accepted KM practices. The call for papers went out in Fall 2004 and was published in the November 2004 issue ofOrganization. In our call we asked for advances to the discussion rather than mere reiteration of the already appreciated. Our authors and reviewers made great efforts and we learned much from their submissions, both those included and those turned away, and from the many reviews. However, we found deep disagreements, both among our reviewers about the submissions—and among everyone about the topic area generally. Clearly KM frustrates readers, authors, and reviewers alike; hence the temptation to dismiss it as yet another management fad, as many do. But there is an undeniable enthusiasm for KM among managers and academics, so our first thought was ‘To what problem is KM the answer?’. Framing the question well often takes one towards the answer—so if we puzzle out KM's problematics we may find ourselves moving towards the underpinnings we are looking for.

Accounting for resource and service usage in communication networks forms the basis of network operators' business, and is therefore essential. Within a heterogeneous, multidomain mobile environment of emerging new access technologies, the demand for a distributed accounting infrastructure becomes more relevant. Driven by the analysis of current accounting solutions in Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Networks (WLAN) networks, the newly developed approach presents an integrated accounting architecture based on the Diameter protocol, forming a flexible basis for charging UMTS and WLAN communication services. The system developed is described, discussed and evaluated by a prototypical implementation.
