Organizations that make use of computer information systems (CIS) are prototypical complex adaptive systems (CAS). This paper shows how an approach from Complexity Science, exploratory agent-based modeling (ABM), can be used to study the impact of two different modes of use of computer-mediated communication (CMC) on organizational culture (OC) and performance. The ABM includes stylized represe...

User testing tends to put participants in the role of the user. To evaluate complex systems (such as adaptive systems), a Wizard-of-Oz study may be used, where the role of the system is made easier by allowing somebody on the design team to perform part of it. In this paper, we propose a method whereby participants take the role of the system, allowing early user involvement in the design proce...

this paper is concerned with the consensus tracking problem of high order mimo nonlinear multi-agent systems. the agents must follow a leader node in presence of unknown dynamics and uncertain external disturbances. the communication network topology of agents is assumed to be a fixed undirected graph. a distributed adaptive control method is proposed to solve the consensus problem utilizing re...

in this paper, an observer based fuzzy adaptive controller (fac) is designed fora class of large scale systems with non-canonical non-affine nonlinear subsystems. it isassumed that functions of the subsystems and the interactions among subsystems areunknown. by constructing a new class of state observer for each follower, the proposedconsensus control method solves the problem of unmeasured sta...

some applications are critical and must designed fault tolerant system. usually voting algorithm is one of the principle elements of a fault tolerant system. two kinds of voting algorithm are used in most applications, they are majority voting algorithm and weighted average algorithm these algorithms have some problems. majority confronts with the problem of threshold limits and voter of weight...

Recent scholarship on the appropriation of advanced information technology in professional settings has utilized adaptive structuration theory (AST) to move beyond voluntaristic and deterministic perspectives on workplace interaction. Our study seeks to advance the paradigm of adaptive structuration in both theoretical and empirical terms. First, we make a case for a reconceptualization of the ...

This paper examines the influence exerted on the thought of F.A. Hayek by the work of the biologist and founder of systems theory, Ludwig von Bertalanffy. It is argued first of all that Bertalanffy provided Hayek with a conceptual framework in terms of which he could articulate the philosophical significance of his theoretical psychology. In particular, Bertalanffy’s work afforded Hayek a set o...
