The Council of Pediatric Subspecialties (CoPS) was founded in September 2006 largely due to concerns about the nonuniformity of the fellowship application process. Working with the pediatric subspecialty community, CoPS has been successful in promoting a uniform process with many more pediatric fellowship programs now using a matching program and the Electronic Residency Application Service. Mo...

Policy based management is being adopted widely for different domains like QoS, security and VPNs in order to allow new services and facilitate network management. Also, the interface to the network device and the information models required for specifying policies are either standardized or being standardized in IETF and DMTF. This paper reports the design, implementation, and performance eval...

We consider a variant of the game of Cops and Robbers, called Containment, in which cops move from edge to adjacent edge, the robber moves from vertex to adjacent vertex (but cannot move along an edge occupied by a cop). The cops win by “containing” the robber, that is, by occupying all edges incident with a vertex occupied by the robber. The minimum number of cops, ξ(G), required to contain a ...

The cops-and-robber (CR) game has been used in mobile robotics as a discretized model (played on a graph G) of pursuit/evasion problems. The “classic” CR version is a perfect information game: the cops’ (pursuer’s) location is always known to the robber (evader) and vice versa. Many variants of the classic game can be defined: the robber can be invisible and also the robber can be either advers...

Stefan Vogler and Valerie Jenness on community views toward cops.

Knowledge co-creation at the boundaries of communities practice (CoPs) can lead to heightened tensions and power struggles. This study examines how struggles among CoPs begin structure knowledge creation processes. Drawing on a qualitative case new medical research project, shows negotiations became manifested through conflicting discursive positioning coercive affecting efforts. One CoP adopte...

We consider a Cops-and-Robber game played on the subsets of an n-set. The robber starts at the full set; the cops start at the empty set. In each round, each cop moves up one level by gaining an element, and the robber moves down one level by discarding an element. The question is how many cops are needed to ensure catching the robber when the robber reaches the middle level. Alan Hill posed th...

Symbiotic computing leads to a proliferation of computing devices that allow linking people, favoring the development of distributed Communities of Practice (CoPs). Their members, being dispersed geographically, have to rely strongly on technological means to interact. In this context, coordinating distributed CoPs is more challenging than coordinating their collocated counterparts. Hence, the ...

The purpose of this study is to introduce CoP reward allocation (COREA) system that efficiently solves a mathematical optimization problem to optimally allocate limited financial reward and to promote knowledge sharing activities in CoPs. To test the validity and usefulness of COREA, we simulate three knowledge sharing climates in which the majority of CoPs performs below-, on-, or above-averag...

Tabu Search (TS) is a meta-heuristic search algorithm that is easy to parallelise. E cient parallelisation of TS can represent a signi cant saving in the real-time required to solve a problem over an equivalent sequential algorithm. In this study, a general parallel TS algorithm for solving combinatorial optimisation problems (COPs) is presented. The unique feature of our approach is that the T...
