Purpose – The purpose of this paper is to investigate to which extent the concept of communities of practice (CoPs) can be applied to online communities and to explore how organizations can better utilize online social structures for their knowledge management practice. Design/methodology/approach – A case study was used to examine an online community with the practice-and-identity framework th...

We introduce and study the game of " Selfish Cops and Adversarial Robber " (SCAR) which is an N-player generalization of the " classic " two-player cops and robbers (CR) game. We prove that SCAR has a Nash equilibrium in deterministic strategies.

This paper introduces the Community Assessment Tool (CAT) as a method for the assessment of Communities of Practice (CoPs) and provides an overview of its construction. It shows that the methodology is based on current theories with regard to CoPs and group dynamics. The method was also tested in practice through a pilot and a study among members of 7 communities of practice (N = 271) in order ...

with the development of the science and technology, Complex Product and System (CoPS) plays a more important role in modern economy and society. This paper aims at the problem of quality control in the CoPS innovation. Through studying the CoPS characteristics and different innovation mode from the mass production, we established the quality chain model. The model is a process network in which ...

Invasive infections associated with non-typhoidal Salmonella (NTS) serovars Enteritidis (SE), Typhimurium (STm) and monophasic variant 1,4,[5],12:i:- are a major health problem in infants and young children in sub-Saharan Africa, and currently, there are no approved human NTS vaccines. NTS O-polysaccharides and flagellin proteins are protective antigens in animal models of invasive NTS infectio...

Purpose – The complexity and responsibilities of public health make collaboration across multiple levels of government critical. The Centers for Disease Control and Prevention (CDC) effectively uses communities of practice (CoPs) to bring its staff together with partners to share, learn, and address public health problems. This paper aims to focus on CoPs. Design/methodology/approach – The pape...

This paper describes and evaluates a framework for managing Differentiated Services (diffserv) configuration on Mobile IP-based networks. In the considered scenario, users can keep their QoS privileges while they move along through different access networks interconnected by a diffserv domain. In this case, the edge routers receive the diffserv configuration dynamically, according to the authen...

Vertex pursuit games, such as the game of Cops and Robber, are a simplified model for network security. In these games, cops try to capture a robber loose on the vertices of the network. The minimum number of cops required to win on a graph G is the cop number of G. We present asymptotic results for the game of Cops and Robber played in various stochastic network models, such as in G(n, p) with...

A Communities of Practice (CoPs) approach was used to enhance interprofessional practice in seven clinical sites across Alberta. Participating staff were free to decide the area of practice to focus on and the actions to be implemented. All practice changes implemented by the CoPs related to either improving communications (e.g., introduction of joint care meetings) or information transfer (e.g...

Organizations have the potential to achieve advantage through communities of practice (COPs) initiatives. However, establishing and sustaining COPs is a challenging task. Facilitation is needed to help COPs overcome difficulties throughout their life stages. Facilitators take on leadership roles within these virtual communities, yet little is known about the challenges related to their roles. T...
