The Network of Innovators in Jena: An Application of Social Network Analysis
No full textWe apply social network analysis methods to describe the evolution of the innovator network of Jena, Germany in the period from 1995 to 2001. We find this evolution to be directed towards an increasing focus on core competencies of the local innovation system. Further we analyze the network resulting from R&D cooperations and explain - by means of network regression techniques - that the job mobility of scientists and the technological overlap between the actors, rather than past cooperations, can best predict the resulting structure. We also observe an increasing importance of the university while the former "Kombinate" begin to lose their prominent role.Innovator Networks, Network Regression, Local Innovation Systems, R+D Cooperation, Research University
Cooperation and Specialization in German Technology Regions
No full textWe investigate cooperative behavior within technology regions in patenting activities. Case studies of local innovation systems point out certain characteristics fruitful to innovation and regional growth but often pronounce historical singularities as major influence. We provide evidence on the same theoretical basis in an econometric study. Based on a theoretical discussion of research cooperation hypotheses are derived which relate a regions technological characteristics to that regions account of research cooperation. Patent data are used to define the technological specialization of German regions and identify cooperations within and between them. Most cooperations tend to take place in modestly specialized regions, indicating a need for similar technological capabilities between partner firms.
Replication Data for: Regional Innovator Networks - A Review and an Application with R
No full textThis is a subset of the OECD REGPAT database (February 2016) and the HAN database (September 2016). The complete data can be downloaded from http://www.oecd.org/sti/intellectual-property-statistics-and-analysis.htm#ipdata. This subset is used as an example for the analysis of regional innovator networks and covers selected tables on EPO applications with at least one inventor located in four German regions (Berlin, Hamburg, Munich, Stuttgart).
The dataset also includes the R code for replication, OECD documentation files, and four text files used for (rough) cleaning of inventor names

Public Research in Regional Networks of Innovators: A Comparative Study of Four East-German Regions
No full textUniversities and public research organizations are said to be an integrative and essential element of a functioning innovation system as they play a vital role not only in the generation of new technological knowledge, but also in its diffusion. We analyse four East German local networks of innovators which differ in structure and innovative performance and investigate the characteristic role of public research within these local systems by applying methods of social network analysis. Our results show that universities and non-university institutions of public research are key actors in all regional networks of innovators both in terms of patent output and in terms of centrality of their position in the networks. Further we find the 'thicker' networks to have more central public research organizations. Higher centrality of public research compared to private actors may be due to the fact that universities are explicitly designed to give away their knowledge and that they increasingly face the need to raise external funds.Innovator Networks; Public research; R+D Cooperation; Mobility

Kritische Normenforschung in den Internationalen Beziehungen
No full textConstructivist norm research is a lively and growing research programme in the field of international relations. Unsurprisingly, its increasing differentiation over the last three decades has raised questions about the ability to communicate across different academic camps. This edited volume enables dialogue by identifying commonalities and differences among academic camps from a metatheoretical perspective. The authors theoretically and empirically highlight new paths for critical norm research, foregrounding reflexivity and contingency, and critically discussing key concepts such as contestation, intersubjectivity and normativity. In this way, they reveal new paths towards critical norm research in this field. With contributions by Stephan Engelkamp, Sassan Gholiagha, Katharina Glaab, Antonia Graf, Hannes Hansen-Magnusson, Eva Herschinger, Maren Hofius, Daniel Jacobi, Kai Koddenbrock, Friederike Kuntz, Bastian Loges, Holger Niemann, Judith Renner, Frank Sauer, Henrik Schillinger, Linda Wallbott and Lisbeth Zimmermann.PublishedDie konstruktivistische Normenforschung hat sich in den letzten 30 Jahren fest in den Internationalen Beziehungen etabliert. Ständige Ausdifferenzierungen werfen Fragen nach der Möglichkeit des Austausches zwischen den unterschiedlichen wissenschaftlichen Lagern auf. Aus metatheoretischer Perspektive benennt der Band Unterschiede und Gemeinsamkeiten der Ansätze und bietet eine gemeinsame Sprache für den Dialog an. Die AutorInnen des Bandes legen theoretische und empirische Beiträge vor, die Kontextgebundenheit, Situiertheit und die Reflexivität gegenüber dem Forschungsgengenstand zeigen und diskutieren zentrale Konzepte von Umstrittenheit, Intersubjektivität und Normativität. Somit werden neue Wege der kritischen Normenforschung aufgezeigt.
