Sociological and Communication-Theoretical Perspectives on the Commercialization of the Sciences
Loet Leydesdorff
Both self-organization and organization are important for the further development of the sciences: the two dynamics condition and enable each other. Commercial and public considera…
Where is Synergy Indicated in the Norwegian Innovation System? Triple-Helix Relations among Technology, Organization, and Geography
Øivind Strand, Loet Leydesdorff
Using information theory and data for all (0.5 million) Norwegian firms, the national and regional innovation systems are decomposed into three subdynamics: (i) economic wealth gen…
Innovation Systems as Patent Networks: The Netherlands, India and Nanotech
Wilfred Dolfsma, Loet Leydesdorff
Research in the domain of 'Innovation Studies' has been claimed to allow for the study of how technology will develop in the future. Some suggest that the National and Sectoral Inn…
University-Industry-Government Relations in China: An emergent national system of innovations
Loet Leydesdorff, Zeng Guoping
Since 1992, a new Chinese innovation system has been emerging in terms of university-industry-government relations. In recent years, science parks, incubators, and high-tech develo…
The Triple Helix Model and the Meta-Stabilization of Urban Technologies in Smart Cities
Loet Leydesdorff, Mark Deakin
The Triple Helix model of university-industry-government relations can be generalized from a neo-institutional model of networks to a neo-evolutionary model of how three selection…
Normalization, CWTS indicators, and the Leiden Rankings: Differences in citation behavior at the level of fields
Loet Leydesdorff, Tobias Opthof
Van Raan et al. (2010; arXiv:1003.2113) have proposed a new indicator (MNCS) for field normalization. Since field normalization is also used in the Leiden Rankings of universities,…
A comparative study on communication structures of Chinese journals in the social sciences
Ping Zhou, Xinning Su, Loet Leydesdorff
We argue that the communication structures in the Chinese social sciences have not yet been sufficiently reformed. Citation patterns among Chinese domestic journals in three subjec…
The Decline of University Patenting and the End of the Bayh-Dole Effect
Loet Leydesdorff, Martin Meyer
University patenting has been heralded as a symbol of changing relations between universities and their social environments. The Bayh-Dole Act of 1980 in the USA was eagerly promot…
Competing Technologies: Disturbance, Selection, and the Possibilities of Lock-in
Loet Leydesdorff, Peter Van den Besselaar
Arthur's (1988) model for competing technologies is discussed from the perspective of evolution theory. Using Arthur's own model for the simulation, we show that 'lock-ins' can be…
Is Inequality Among Universities Increasing? Gini Coefficients and the Elusive Rise of Elite Universities
Willem Halffman, Loet Leydesdorff
One of the unintended consequences of the New Public Management (NPM) in universities is often feared to be a division between elite institutions focused on research and large inst…
Technological Developments and Factor Substitution in a Complex and Dynamic System
Loet Leydesdorff, Peter Van den Besselaar
Schumpeter's (1939) distinction between changes in the form of the production function corresponding to innovation, and shifts along the production function corresponding to factor…
Scaling Trajectories in Civil Aircraft (1913-1997)
Koen Frenken, Loet Leydesdorff
Using entropy statistics we analyse scaling patterns in terms of changes in the ratios among product characteristics of 143 designs in civil aircraft. Two allegedly dominant design…
Regional innovation systems in Hungary: The failing synergy at the national level
Balazs Lengyel, Loet Leydesdorff
We use entropy statistics in this paper to measure the synergies of knowledge exploration, knowledge exploitation, and organizational control in the Hungarian innovation system. Ou…
Longitudinal Trends in Networks of University-Industry-Government Relations in South Korea: The Role of Programmatic Incentives
Han Woo Park, Loet Leydesdorff
This study examines the longitudinal trend of systemness in networked research relations in South Korea using a triple-helix (TH) indicator of university-industry-government (UIG)…
Scientometrics and the evaluation of European integration
Koen Frenken, Loet Leydesdorff
In this chapter, we elaborate on the topic of European integration in science. We will not deal with questions related to the effects of European integration, but only with the sci…
Anticipation in Social Systems: the Incursion and Communication of Meaning
Loet Leydesdorff, Daniel M. Dubois
In social systems, meaning can be communicated in addition to underlying processes of the information exchange. Meaning processing incurs on information processing with hindsight,…
