We present a dynamic model of knowledge management in which knowledge sharing influences organizational culture. Employees’ fit with the organizational culture improves with the sharing and learning of common organizational practices. We analyze the impact of providing incentives for knowledge sharing as well as the investment of information technology in shaping knowledge sharing. Using analyt...

It is well-known that uncontrolled change to software can lead to increasing evolution costs caused by deteriorating structure and compromised system qualities. For complex systems, the need to carefully manage system evolution is critical. In this paper we outline an approach to managing evolution of object-oriented (OO) software. The approach is based on a goal-directed, cyclic process, in wh...

One of the recently addressed research directions focuses on the problem of mining topic evolutions from textual documents. Following this main stream of research, in this paper we face the different, but related, problem of mining the topic evolution of entities (persons, companies, etc.) mentioned in the documents. To this aim, we incrementally analyze streams of time-stamped documents in ord...

Even under the best circumstances, organizational change generates resistance. When the change results from a company in one country purchasing a plant in a different country, the complexity of change management and the resistance to change increase considerably. This case analysis examines one such change effort. Initially, the effort failed because the management of the acquiring (U.S.) firm ...

In this paper we address the problem of schema evolution in object-oriented database systems. Most currently available database prototypes either completely lack schema evolution facilities, or ooer a restricted set of special purpose schema evolution operators supporting simple schema changes. Our approach is diierent. We consider schema objects as objects like others and have the meta schema ...

To commit credibly in bargaining is crucial: In the ultimatum game with its one– sided early commitment power the “proposer” gets (nearly) the whole pie while the “responder” is left with (almost) nothing. When both parties commit simultaneously the (a)symmetric Nash(1950)–bargaining solution, however, predicts (more or less) equal shares. Relying on a continuous connection of these two games b...

In market-driven software evolution, the objectives of a requirements engineering process include the continuous management of new and changed requirements in a way that ensures competitiveness on the market place. This paper compares two independently developed industrial market-driven requirements engineering processes, which both apply continuous requirements management using state-oriented ...

One of the important functions of financial intermediation is intertemporal risk smoothing. This paper studies the effects of a production shock in a closed economy and compares the abilities of market-based and bank-based financial systems in processing the shock. The analysis of the shock propagation indicates that a competitive banking system may collapse in absence of a proper regulation. P...
