A subset in a groupG ≤ Sym(n) is intersecting if for any pair of permutations π, σ in the subset there is an i ∈ {1, 2, . . . , n} such that π(i) = σ(i). If the stabilizer of a point is the largest intersecting set in a group, we say that the group has the Erdős-Ko-Rado (EKR) property. Moreover, the group has the strict EKR property if every intersecting set of maximum size in the group is the ...

Organizations develop and implement Electronic Knowledge Repositories (EKRs) to support the codification, storage and reuse of knowledge. EKRs are seeing increased use in expert technical professions, such as system administration. Sysadmin.nasa.gov is such an EKR, initiated and supported by a grass-roots group of security and system administrator (sysadmin) professionals. The site supports sev...

BACKGROUND Haemodialysis outcome cannot be improved by increasing the dialysis session dose above the current standard in conventional schedules. Promising results have been reported from daily dialysis, but the optimal dose has not been established. METHODS Weekly eKt/V, equivalent renal clearance (EKR) and stdKt/V were compared retrospectively in 588 complete urea kinetic modelling sessions...

BACKGROUND Many haemodialysis patients have residual renal function (RRF), which as such is insufficient to maintain satisfactory quality of life but reduces the demands of treatment and improves outcomes. In incremental dialysis, the dose is adjusted according to RRF, but how should it be done? METHODS Urea generation rate (G) and distribution volume (V) were determined by the double-pool ur...

Knowledge is a critical resource that can help organizations to sustain strategic advantage in competitive environments. Organizations in Asia and elsewhere are turning to knowledge management (KM) initiatives and technologies to leverage their knowledge resources. As a key component of KM initiatives, electronic knowledge repositories (EKR) are deployed by organizations to store codified knowl...

Knowledge is recognized as a vital asset in organizations. A large number of organizations are implementing knowledge management systems (KMS) in order to leverage their knowledge resources, a common form of which are electronic knowledge repositories (EKR). Since EKR implementation is costly, management needs to be aware of the factors that will make EKR more usable in order to reap benefit fr...

For a graph G, vertex v of G and integer r ≥ 1, we denote the family of independent r-sets of V (G) by I(r)(G) and the subfamily {A ∈ I(r)(G) : v ∈ A} by I v (G); such a subfamily is called a star. Then, G is said to be r-EKR if no intersecting subfamily of I(r)(G) is larger than the largest star in I(r)(G). If every intersecting subfamily of I v (G) of maximum size is a star, then G is said to...

Organizations are attempting to leverage their knowledge resources by employing knowledge management (KM) systems, a key form of which are electronic knowledge repositories (EKRs). A large number of KM initiatives fail due to reluctance of employees to share knowledge through these systems. Motivated by such concerns, this study formulates and tests a theoretical model to explain EKR usage by k...

Knowledge forms an important asset in modern organizations. In order to gain and sustain competitive advantage knowledge has to be managed. One aspect of this is to use Electronic Knowledge Repositories (EKR) to enhance knowledge sharing, reuse and learning. The success of an EKR is dependent on the quality of its content. For knowledge to be stored in an EKR, it has to be captured. One crucial...

This paper is based on the context of electronic knowledge repositories (EKR). There are many problems in people using EKR to share knowledge. We can classify these problems into three types: 1) Free-riding situation, 2) Non-use situation, 3) Dormant situation. Many organizations use rewards to motivate people to contribute knowledge into EKR, but there has been no conclusive evidence of the ro...
