Alliances represent a variety of governance contexts, and hence provide a rich empirical setting for studying the value-creation mechanisms of Information Technology (IT). We examine the influence of IT investment and flexible IT infrastructure, through Service Oriented Architecture (SOA), in the effect of alliance activity on firm performance. We find that the marginal contribution of each joi...

Hidden Markov models (HMMs) are one of the most popular and successful statistical models for time series. Observable operator models (OOMs) are generalizations of HMMs that exhibit several attractive advantages. In particular, a variety of highly efficient, constructive, and asymptotically correct learning algorithms are available for OOMs. However, the OOM theory suffers from the negative pro...

Semantic integration is important in constructing electronic marketplaces (e-marketplaces). Although many previous researches have been done, the task of semantic integration and the mechanism of maintaining semantic consistency are still not well known. This paper proposes a Collaboration-Role-Based Semantic Integration Mechanism (CRB-SIM). It promotes collaboration as a key means of resolving...

This article is an attempt to promote R&D methodology that is actionoriented in order to improve the development of tele-learning environments and software artefacts fully adapted to learning activities. First we start by presenting an overview of the two main phases of action-oriented research, stressing the importance of control methods. Secondly, we describe difficulties in applying these me...

In healthcare domain, reporting of laboratory results by biomedical scientists to caregivers is a common practice. Many healthcare centres follow different kind of guidelines for reporting laboratory results for the purpose of improving the process. In this paper, we first analyze current procedure for reporting Critical Laboratory Results (CLRs) followed by North Estonia Medical Centre (NEMC) ...

1. An overview of the problem My aim is to trace the thinking-in-change (Noss & Hoyles, 1996) during the co-ordination of two epistemologically distinct faces of distribution. By co-ordination here, I refer to the connection between a data-centric perspective on distribution, which identifies distribution as an aggregated set of actual outputs, and a modelling perspective on distribution, which...
