  1. Lessons from improvisation or market led theories

    Moreno Bragado, Elisa

  2. Lessons from Evolutionary Stage Led Theories

    Govindaraju, Rajesri; Swagerman, Dirk

  3. Shared services in accounting and finance

    Swagerman, Dirk; Steenis, Jorn van
    The purpose of this paper is to present examples of the current state of the Shared Services Concept as applied to the finance function. The paper arises out of the ongoing research after current developments in the finance function enabled by information and communication technology, at the University of Twente. The rapid developments in information and communication technology (leading to new ‘economics of information’) combined with developments in organisation theory, have far-reaching implications for the way activities are best organised (‘the new economics of organisation’). As a result, organisations are being restructured, and boundaries of organisations are shifting. These developments...

  4. Introduction: organizational virtualness and electronic business

    Wassenaar, Arjen

  5. Lessons From Managerial Theories for Improving Virtualness in Electronic Business

    Wassenaar, Arjen; Govindaraju, Rajesri; Moreno Bragado, Elisa; Raesfeld Meijer, Ariane von; Ribbers, Pieter; Swagerman, Dirk
    Electronic business and virtual organisations are important research topics in the IS research community today. At the same time these research topics are very appropriate for interdisciplinary research. The panel aims: - presentation of lessons from managerial theories for improving organisational virtualness; - exploration possibilities for interdisciplinary oriented research forum of the phenomenon virtual organisations in electronic business. Chapter 1 discusses electronic business and the role of information and communication technology (ICT) in changing fundamentally electronic business transaction patterns between economic actors. New intra- and inter-organisational structures are emerging, known under labels like virtual organisation, virtualisation and organisational virtualness. These emergent virtual organisational structures will...

  6. Lessons from Strategic Choice Led Theories

    Wassenaar, Arjen

  7. Applied semiotics

    Stamper, Ronald

  8. Simplicity, uniformity and quality: the role of semantic analysis in systems development

    Liu, K.; Ades, Y.; Stamper, R.
    Industrial experience shows that heavy investment in IT does not always bring in a satisfactory economic return due to very often quality problems, which was partly caused by inadequacy of user requirements analysis and representation. Semantic Analysis, a method developed for analysing and specifying user requirements based on an 'agent-in-action' ontology, has demonstrated a way to improve software quality. The semantic structure is preserved through design and implementation in order to produce a satisfactory system. To this end, a set of methods and tools for systems engineering has be developed around Semantic Analysis and supported by Normbase. This approach has...

  9. A semiotic theory of information and information systems

    Stamper, Ronald

  10. Ontological dependency

    Stamper, Ronald
    Successful ontological analysis depends upon having the right underlying theory. The work described here, exploring how to understand organisations as systems of social norms found that the familiar objectivist position did not work, eventually replacing it with a radically subjectivist ontology which treats every thing, relationship and attribute as a repertoire of behaviour as uderstood by some responsible agent. Gibson’s Theory of Affordances supports this view in relation to our physical reality and the concept of norms extends the theory naturally into the social domain. A formalism, Norma, which captures the need always to specify the responsible agent and some...

    Scheer, Lieke van der; Boenink, Marianne

  12. The effectiveness of percutaneous vertebroplasty is determined by the patient-specific bone condition and the treatment strategy

    Widmer Soyka, Rene P.; Helgason, Benedikt; Hazrati Marangalou, Javad; Bergh, Joop P. van den; Rietbergen, Bert van; Ferguson, Stephen J.
    Purpose Vertebral fragility fractures are often treated by injecting bone cement into the collapsed vertebral bodies (vertebroplasty). The mechanisms by which vertebroplasty induces pain relief are not completely understood yet and recent debates cast doubt over the outcome of the procedure. The controversy is intensified by inconsistent results of randomized clinical trials and biomechanical studies that have investigated the effectiveness or the change in biomechanical response due to the reinforcement. The purpose of this study was to evaluate the effectiveness of vertebroplasty, by varying the relevant treatment parameters and (a) computationally predicting the improvement of the fracture risk depending on the...

  14. Effect of Discontinuation of Inhaled Corticosteroids in Patients with Chronic Obstructive Pulmonary Disease: the COPE study

    Valk, Paul van der; Monninkhof, Evelyn; Palen, Job van der; Zielhuis, Gerhard; Herwaarden, Cees van
    The aim of this double-blind single center study (the COPE study) was to investigate the effect of discontinuation of the inhaled corticosteroid fluticasone propionate (FP) on exacerbations and health-related quality of life in patients with chronic obstructive pulmonary disease. After 4 months of treatment with FP (1,000 μg/day), 244 patients were randomized to either continue FP or to receive placebo for 6 months: 123 patients continued FP (FP group), and 121 received placebo (placebo group). In the FP group, 58 (47%) patients developed at least one exacerbation compared with 69 (57%) in the placebo group. The hazard ratio of a...

  15. Supporting the legal practitioner: LKBS or web?

    Leenes, Ronald; Svensson, Jörgen
    The legal practitioner is a knowledge worker. Two distinct technologies may be of assistance to this type of professional: legal knowledge‐based system technology and Internet World Wide Web technology. In this paper we investigate the relation between legal knowledge‐based systems and the Internet. Legal knowledge‐based systems have long been surrounded by much optimism, but despite the efforts over the last 20 years, the number of practical applications actually in use is still small. On the other hand, the WWW technology, which in a practical form has been around for only a few years, is gaining momentum and is expected to...

  18. Burden of proof in legal dialogue games

    Leenes, Ronald
    In recent years dialectics have received considerable attention in the field of Artificial Intelligence and law. A sub-branch of this field concentrates on the development of dialogue games. Many of these legal dialogue systems are fairly simple. As a consequence they are not very realistic as compared to actual legal procedures. In this paper I discuss a legal dialogue game (DiaLaw) and compare this model to a specific type of legal procedure, the Dutch civil summons procedure. The focus of the description is on the burden of proof in both dialogue game and actual procedure. The paper shows what computational...

  19. Burden of proof in dialogue games and Dutch civil procedure

    Leenes, Ronald E.
    In recent years dialectics has become popular in Artificial Intelligence and law. A sub-branch of this field concentrates on the development of dialogue games. Many of these legal dialogue systems are fairly simple, in some respects even too simple. Among the topics dialogue games can improve on, is the division of the burden of proof. In this paper I discuss some legal dialogue games in the light of an actual legal procedure to show the shortcomings of these models. The paper shows what computational dialectics can learn form legal practice.
