Toufic M. El Masri
- Der DIBOGS e.V. ist aus dem Duisburg-Ilmenau-Bayreuther Oberseminar zur Gesund-heitsökonomik und Sozialpolitik (DIBOGS) hervorgegangen. Der Verein hat sich zum Ziel gesetzt, den wissenschaftlichen Nachwuchs auf dem Gebiet der Wirtschaftswissenschaften in den Forschungsfeldern Gesundheitsökonomik, Gesundheitspolitik und Sozialpolitik zu fördern. Zu den Aktivitäten des Vereins zählt u.a. ein gesundheitsökonomischer Workshop, der erstmalig im Jahr 2005 ausgerichtet wurde und der sich zentral an gesundheitsökonomische Nachwuchswissenschaftler richtet. Ziel ist es, einen möglichst regen Erfahrungsaustausch herbeizuführen und insofern Unterstützung bei der Vorbereitung und Durchführung von Dissertations- oder Habilitationsvorhaben, sowie sonstigen wissenschaftlichen Projekten oder Publikationen zu bieten.
Der Workshop stellt nicht die Präsentation an sich, sondern den Austausch über das jeweilige Thema in den Mittelpunkt. Alle Papiere gehen den Teilnehmern im Vorfeld zu. Während des Workshops stehen für jedes Papier 45 Minuten zur Verfügung. Ein Koreferent setzt sich in-tensiv mit dem Papier auseinander, darauf schließt sich eine Diskussion unter den Teilnehmern an. Mittlerweile (seit 2006) gibt es zu jedem Workshop einen Sammelband, der die (fach)politische Öffentlichkeit über diskutierte Themen informieren soll.
Der vorliegende Band „DIBOGS-Beiträge zur Gesundheitsökonomik und Sozialpolitik“ enthält - im Gegensatz zu den Überblicksartikeln aus den Vorjahren - die Zusammenfassungen/Abstracts ausgewählter Beiträge des siebten Duisburg-Ilmenau-Bayreuther Oberseminars zur Gesundheitsökonomik und Sozialpolitik (DIBOGS), das am 23. November 2012 in Düsseldorf stattgefunden hat. Die Zusammenfassung soll einen ersten Überblick über die diskutierten Papiere geben, die unter den ggf. jeweils angegeben Links auch im Detail gelesen werden können. Weitere Informationen zum Sammelband sowie zur Teilnahme am Workshop entnehmen Sie bitte der Webseite www.dibogs.biz.
Measurement of emotional reactions to television advertisements – A state of the art review
- Human emotions and their measurement present a complex and intricate affair
which perpetuates an ongoing discourse in marketing research. Since emotions
play a pivotal role in the success of advertisements, the exploitation of tools for
their precise measurement is crucial to researchers and practitioners alike. Yet,
there is no single gold standard instrument existent that enables a comprehensive
detection of all emotion facets at once. This thesis therefore focuses on the theoretical
conceptualization of emotion, and afterwards presents a variety of measurement
methods that address different emotion components. Thereby, particular
emphasis is placed on their applicability as regards television commercials.
The service-productivity learning cockpit – a business intelligence tool for service enterprises
- The paper describes the development of an agent-based simulation tool for hospital managers to manage their productivity of services, especially in the context of supporting services like patient transport logistics. The learning cockpit allows hospital managers to see how the change of inputs changes the overall perceived customer values of all stakeholders and therefore to get a visualization of the impacts their decisions cause. The paper introduces the general research domain service-productivity, followed by a description of the development steps of artefact creation. The learning cockpit is part of a research project called BELOUGA, which is funded by the German government.
Theoretical and Computation Basis for CATNETS - Annual Report Year 3
- In this document the developments in defining the computational and theoretical framework for economical resource allocation are described. Accordingly the formal specification of the market mechanisms, bidding strategies of the involved agents and the integration of the market mechanisms into the simulator were refined.
The BabelNEG System - A Protocol-generic Infrastructure for Electronic SLA Negotiations in the Internet of Services
- Visions of the next-generation Internet of Services are driven by digital resources traded on a global scope. For the resulting economic setting, automated on-line techniques for handling services and resources themselves, for advertising and discovering as well as for the on-the-fly negotiation of proper terms for their use are needed. Hence, a flexible infrastructure for the respective management of services and associated service level agreements is mandatory. This thesis presents the results of my dissertation project. They comprise a service infrastructure, able to support the structured discovery and protocol-generic negotiation of electronic service level agreements (SLAs) and thus services themselves.
The Effects of Project Management Mechanisms on Innovation Performance in Hi-Tech Firms: Mediation of Teamwork Processes and Moderating Effects of Different Team Members’ Cultural Values
- High tech firms increasingly form innovation projects composed of team members with different cultural backgrounds to respond to their customers’ needs. Prior studies have regarded these cross cultural innovation projects as an important instrument for developing innovative products, yet little effort has been investigated on the issue of the effect of project management mechanisms (autonomy and control) on these projects and the impacts of team members’ cultural backgrounds on different project management mechanisms. Moreover, prior studies have neglected to bridge the gap between the effect of these project management mechanisms on communication and coordination of teamwork processes. Therefore, this study aims to fulfill the gaps in project management and cross cultural study by exploring the effects of different project management mechanisms on several types of innovation performance. In particular, it examines the relationships of these project management mechanisms on innovation performance mediated by the teamwork processes and moderated by the different backgrounds of team members represented by their cultural values. Structural equation modelling was used to test all hypotheses from 434 new product development project team members. The results indicated that control mechanisms had stronger effects on innovation performance than providing autonomy. Additionally, the study showed that all project management mechanisms (autonomy and control mechanisms) had indirect effects on radical innovation and project efficiency through communication and coordination. However, these control mechanisms had indirect impacts on incremental innovation only through coordination but not communication. Importantly, this study revealed that control mechanisms could apply to the team members with different cultural backgrounds in encouraging higher innovation performance. In order to enhance higher innovation performance, the suggestions to apply the appropriate project management mechanisms to their team members with different cultural backgrounds are provided.
Towards the Governance of Open Distributed Grids - A Case Study in Wireless Mobile Grids
- New networking technologies such as wireless mobile grids and peer-to-peer middleware are examples of a growing class of open distributed systems whose strength is the absence of a central controlling instance and which function through the cooperation of autonomous entities that voluntarily commit resources to a common pool. The social dilemma in such systems is that it is advantageous for rational users to access the common pool resources without making any commitment of their own. This is commonly known as “free-riding”. However, if a substantial number of users followed this selfish strategy, the system itself would fail, depriving all users of its benefits. In this dissertation, we demonstrate how governance decisions can induce cooperation in such systems and how normative frameworks in combination with multi-agent system simulations can be successfully employed to analyse their effects, even at an early development stage. We show that our approach is not only practical and powerful, but also easily accessible. We demonstrate its functionality by implementing a prototype to explore the impact of enforcement mechanisms on wireless mobile grids, a concept which has been proposed to address the energy issues arising in the next generation of mobile phones and the networks that connect them. We also infer lessons from this example for open distributed systems in general. Simulation experiments quantify the benefits of enforcement mechanisms for wireless mobile grids. We analyse these results with respect to the costs of enforcement as well as further criteria that reflect the interests of the multiple stakeholders in the system. We conclude with some observations on how the lessons learned from both process and outcomes may be applicable to the broader context of open distributed systems. In particular, we highlight (i) the use of simulation using intelligent agents and a normative framework as a means for in silico exploration of complex systems for both business and technological objectives, and (ii) the insight offered into a range of enforcement mechanisms and a better understanding of the conditions and constraints under which they are applicable.
Tagungsband zum Doctoral Consortium der WI 2011

Proceedings of the 12th European Agent Systems Summer School Student Session
- This volume contains the papers presented at the Student Session of the 12th European Agent Systems Summer School (EASSS) held on 25th of August 2010 at Ecole Nationale Superieure des Mines de Saint-Etienne, France. The Student Session, organised by students, is designed to encourage student interaction and feedback from the tutors. By providing the students with a conference-like setup, both in the presentation and in the review process, students have the opportunity to prepare their own submission, go through the selection process and present their work to each other and their interests to their fellow students as well as internationally leading experts in the agent field,both from the theoretical and the practical sector.
Reputation in Multi Agent Systems and the Incentives to Provide Feedback
- The emergence of the Internet leads to a vast increase in the number of interactions between parties that are completely alien to each other. In general, such transactions are likely to be subject to fraud and cheating. If such systems use computerized rational agents to negotiate and execute transactions, mechanisms that lead to favorable outcomes for all parties instead of giving rise to defective behavior are necessary to make the system work: trust and reputation mechanisms. This paper examines different incentive mechanisms helping these trust and reputation mechanisms in eliciting users to report own experiences honestly.
