Distributed knowledge and transactive processes in decision-making groups.
ABSTRACT Presents a model that examines the relations between group members' individual knowledge, communication processes, and group decisions. The model proposes that communication processes involved in effective information exchange change depending on the degree to which information needed for an effective group decision is known by all, some, one, or no group members, and on the degree to which members have a shared understanding about who knows what. The model is presented in the form of 9 propositions about 4 processes; comparing individual knowledge, establishing expertise, searching for needed information, and communicating information. Two studies comparing retrieval processes in memory systems are presented. Ss from both studies were heterosexual dating couples who had been dating at least 6 mo and were college students. Ss completed (either 2 or 3 times) a general knowledge task individually or with their partner or strangers. The data suggest that even strangers have a transactive memory system, which improves with task repetition. Strangers began developing their transactive memory system by explicitly establishing relative expertise as indicated by their higher frequency of expertise assertions relative to intimate couples. Knowledge test questions are appended. (PsycINFO Database Record (c) 2012 APA, all rights reserved)

ABSTRACT: A large-scale power system is required to have a new strategy to operate at a higher level of automation, flexibility, and robustness. It is a challenge to get the steady-state model for a high order complex nonlinear power plant. Moreover, the model should be adaptive under the changing environment. In this paper, a multi-agent system-based intelligent steady-state model (MAS-ISSM) is presented as an alternative methodology to identify the steady-state model in a large-scale 600 MW thermal power plant. Design of architectures for single agents and an organization of the multi-agent system will be described as the foundation of the intelligent steady-state model (ISSM). The MAS-ISSM will be utilized in the evaluation process and the set-point scheduler to map various control inputs to power and pressure set-points for multiobjective optimization in the power plant. The procedure is presented through a case study, and its feasibility is demonstrated with the simulation resultsIntelligent Systems Application to Power Systems, 2005.

ABSTRACT: In today's competitive global economy characterized by shorter product life cycles, increased employee turnover, and ubiquitous information technologies, an organization's ability to manage knowledge may be the only remaining source of competitive advantage Drucker, 1995; 1999. Even though a number of researchers have outlined the importance of adopting knowledge management KM practices and many organizations have given lip service to the term, there is still some ambiguity concerning what KM actually is and little attention has been paid to factors that enable effective KM to occur. This research uses technical and human-centric approaches combined with Holsapple and Joshi's 1998 Kentucky Initiative to investigate KM within a small information technology group. Based on the findings of our case study, we propose some factors that seem to enable effective KM and a modification to Holsapple and Joshi's architecture of a KM episode.IRMJ. 01/2002; 15:13-21.

ABSTRACT: Transactive memory system (TMS) theory explains how expertise is recognized and coordinated in teams. Extending current TMS research from a group information-processing perspective, our article presents a theoretical model that considers TMS development from a social identity perspective. We discuss how two features of communication (quantity and quality) important to TMS development are linked to TMS through the group identification mechanism of a shared common team identity. Informed by social identity theory, we also differentiate between intragroup and intergroup contexts and outline how, in multidisciplinary teams, professional identification and perceived equality of status among professional subgroups have a role to play in TMS development. We provide a theoretical discussion of future research directions aimed at testing and extending our model.Group & Organization Management 01/2012; 37(2):204-240. · 2.43 Impact Factor
