The seminar is based on the speaker’s two recent papers.

(1) We study regional patterns of scientific knowledge production in Europe using all scientific publications in the period 2000–2014 attributed to 813 scientific subfields. We show that the existing scientific portfolio of regions offers opportunities for related diversification and discourages the creation of knowledge on topics unrelated to the local knowledge base. Many lagging regions show clear growth, but complex knowledge production remains highly concentrated in regions in the North and West of Europe. For lagging regions there are advantages in not specializing too soon and to first diversify before moving into developing more complex knowledge.

(2) Researchers holding multiple affiliations can play an important bridging role between organizations, fostering knowledge transfer and research collaboration. We propose a methodology to identify authors with multiple affiliations co-hosted by two organizations for a prolonged period of time, which distinguishes them from authors who change jobs or only hold short appointments. We apply this methodology to all authors and organizations residing in the Netherlands and find 626 organizations with at least one co-affiliated researcher. We perform a regression analysis of the inter-organizational network spanned by all co-affiliated researchers, and find strong negative effects of travel time. We also find that researchers who hold multiple affiliations, often cross the institutional boundaries between university, industry, government, healthcare and public research organizations. In particular, university-affiliated researchers tend to be most active in bridging to organizations in other institutional spheres. We end with some reflections for future studies and implications for science policy.

Speaker bio

Alfredo Yegros is a senior researcher at the Centre for Science and Technology Studies (CWTS) of Leiden University in the Netherlands. He earned PhD in Information Science from Universitat Politècnica de València. Before joining CWTS, he had research experiences at Science and Policy Research Unit (SPRU) at the University of Sussex, Spanish National Research Council (CSIC), as well as Institute for Innovation and Knowledge Management INGENIO (CSIC-UPV). His research revolves around quantitative studies of science, technology and innovation. His specific research interests embrace, among others, public-private interactions and knowledge flows, science-technology linkages, and relationship between science/technology and innovation.
