Abstract

The continuing growth of Web 2.0 applications and the increased collaboration through these socio-technical platforms reorder whole disciplines and industries. The resultant facilitation of worldwide communication and cooperation also offers compelling opportunities for education and research. With Open Access as basic paradigm, Science 2.0 refers to new practices of researchers who publish, communicate or organize their work by using Web 2.0 technologies. The research aim of this paper is twofold. Since it is a multi-faceted paradigm and due to its heterogeneous applications difficult to comprehend, we first attempt to define Science 2.0 by delineating it from related concepts. Second, after describing prevalent Science 2.0 applications, we develop a framework for evaluating those. In detail, we address the following research questions: What is Science 2.0? From which applications can a scientist choose from, if he/she wants to apply Science 2.0? Which factors determine the value of a specific Science 2.0 application for an individual scientist or a research group? It is suggested that when calculating the value of a specific application or concept, the expected benefits (e.g., time saving, cost reduction, quality improvement), risks and efforts on the one side, and the suitability to the underlying research purpose on the other side should be taken into account. To be effective for a specific research purpose, the Science 2.0 application has to match the functional focus (Information vs. Communication vs. Organization) and non-functional requirements (e.g. ease of use, reliability) on the one hand. On the other hand, the applications must meet the needs of the respective scientific environment (e.g., research group, target community, content type). As theoretical contribution the paper provides a detailed classification of Science 2.0. In practice, the framework could serve as decision support for an individual scientist or a research team when choosing a Science 2.0 application to work with.

Doves and hawks in economics revisited - An evolutionary quantum game theory-based analysis of financial crises

In: arXiv:0904.2113v1 (currently under review)

Category: Miscellaneous

Abstract

The last financial and economic crisis demonstrated the dysfunctional long-term effects of aggressive behaviour in financial markets. Yet, evolutionary game theory predicts that under the condition of strategic dependence a certain degree of aggressive behaviour remains within a given population of agents. However, as the consequences of the financial crisis exhibit, it would be desirable to change the 'rules of the game' in a way that prevents the occurrence of any aggressive behaviour and thereby also the danger of market crashes. The paper picks up this aspect. Through the extension of the in literature well-known Hawk-Dove game by a quantum approach, we can show that dependent on entanglement, also evolutionary stable strategies can emerge, which are not predicted by classical evolutionary game theory and where the total economic population uses a non aggressive quantum strategy.

Von traditioneller wissenschaftlicher Kommunikation zu „Science 2.0“ - Eine empirische Untersuchung der Nutzung von Social Software in der universitären Forschung

Abstract

Vorliegende Studie fokussiert moderne, auf Web 2.0 und Social Software basieren-de Anwendungen zur Unterstützung wissenschaftlicher Kommunikation und Kollaboration. Der Begriff „Science 2.0“ findet Verwendung im Zusammenhang mit Applikationen wie Wikis, Weblogs, Social-Bookmarking-Dienste oder Social-Networking-Dienste. Open Access, also der freie Zugang zu wissenschaftlicher Literatur und Daten, ist ein zentrales Paradigma von Science 2.0. Der Beitrag stellt Ergebnisse einer Umfrage unter Forschern an deutschen Universitäten vor, welche zu den Themen Kenntnis, Nutzungsgrad und Verwendungsart dieser Werkzeuge befragt wurden.

Science 2.0 refers to new practices of researchers who publish, communicate or organize their work by using Web 2.0 technologies. With Open Access as basic paradigm, typical applications are wikis, weblogs, social networking and social book-marking tools. With an online survey conducted at universities in Germany, this study examines researchers’ knowledge and usage of those applications.

Open Access Models and their Implications for the Players on the Scientific Publishing Market

In: Economic Analysis and Policy (EAP)

Category: Publications in scientific journals [Find it]

Abstract

Open Access (OA) as a new form of distributing scientific literature is broadly accepted by scholars, but in most disciplines the realization of the paradigm is progressing rather slowly. The reason for this lies, on the one hand, in a lack of incentives for individual authors. On the other hand, there are many different approaches to OA and their effects on market participants are complex. In this article we regard the implications of different OA models for scholars, publishers, libraries and funding organizations and try to explain the motivations behind the actions currently taking place on the scientific publishing market.

Open Access to Scientific Literature – Increasing Citations as an Incentive for Authors to Make their Publications Freely Accessible

In: 42th Hawaii International Conference on System Sciences; Hawaii, USA

Category: Proceedings

Abstract

In recent years the scientific journal market faces significant evolutions that may cause major changes in the way of publishing research results. In this connection, open access is the prime alternative to publishing in traditional journals, whose subscription-based business model inhibits the distribution of scientific knowledge. But despite strong support for open access among researchers, today this new paradigm is realized only in a few disciplines. A main reason for this lies in the lack of individual incentives for authors to make their publications freely accessible. In this paper we focus on the argument that open access articles are cited more often than articles in traditional journals. Based on a simulation of the citation network, which emerges on the scientific publishing market, we demonstrate how an individual author can increase her citations, and thus her standing in the community, when switching to open access. Especially first movers may benefit from the change of their publication behavior.

Netzwerke in der Wissenschaft - Auswirkungen von Open Access auf die Verbreitung von Forschungsergebnissen

In: Kortzfleisch, Harald F. O.; Bohl, Oliver (Hrsg.): Wissen, Vernetzung, Virtualisierung; Josef Eul Verlag, Lohmar

Category: Chapter in book

Abstract

Zitationen gelten als zentrales Element im Forschungsprozess und Zitationsnetzwerke liefern eine strukturelle Beschreibung der Wissensverbreitung in einem Fachgebiet. Generiert ein Autor viele Zitate auf seine Artikel, steigert dies zudem seine Reputation innerhalb einer Community. Verschiedene Studien haben gezeigt, dass Artikel, die nach dem Open-Access-Prinzip veröffentlicht werden, also unmittelbar nach Fertigstellung frei und kostenlos im Internet verfügbar sind, häufiger zitiert werden. Der Beitrag behandelt die Frage, ob sich vor diesem Hintergrund für Autoren Anreize ergeben, ihre Artikel frei zugänglich zu machen und inwiefern durch diese Praxis ein Nutzen für die Community (bspw. durch eine schnellere Verbreitung von neuen Forschungsergebnissen) generiert werden kann.

Determinanten des Zeitschriftenpreises - Eine explorative Studie der Zusammenhänge zwischen dem Preis einer wissenschaftlichen Zeitschrift und den Kennzahlen Journal Impact Factor, Zitate, Nutzung und Artikelanzahl

In: ABI-Technik 01/2006; München

Category: Publications in scientific journals

Abstract

This study examines to what extent the price of a scientific journal is correlated to different infometric measures, namely the journal impact factor and the total cites to a journal, the usage of a journal and the number of articles published per year. In order to establish comparability, the data is divided into 13 departments. The results implicate that the price of a journal is to a certain degree determined by the number of articles and cites. In contrast, a correlation between price and journal impact factor cannot be detected.
