The Local Emergence and Global Diffusion of Research Technologies: An Exploration of Patterns of Network Formation
Grasping the fruits of "emerging technologies" is an objective of many
government priority programs in a knowledge-based and globalizing economy. We
use the publication records (in the Science Citation Index) of two emerging
technologies to study the mechanisms of diffusion in the case of two innovation
trajectories: small interference RNA (siRNA) and nano-crystalline solar cells
(NCSC). Methods for analyzing and visualizing geographical and cognitive
diffusion are specified as indicators of different dynamics. Geographical
diffusion is illustrated with overlays to Google Maps; cognitive diffusion is
mapped using an overlay to a map based on the ISI Subject Categories. The
evolving geographical networks show both preferential attachment and
small-world characteristics. The strength of preferential attachment decreases
over time, while the network evolves into an oligopolistic control structure
with small-world characteristics. The transition from disciplinary-oriented
("mode-1") to transfer-oriented ("mode-2") research is suggested as the crucial
difference in explaining the different rates of diffusion between siRNA and
NCSC
Bibliometric mapping as a science policy and research management tool
Bibliometric maps of science are landscapes of scientific research fields created by
quantitative analysis of bibliographic data. In such maps the 'cities' are, for instance,
research topics. Topics with a strong cognitive relation are in each other's vicinity and
topics with a weak relation are distant from each other. These maps have several
domains of application. As a policy supportive tool they can be applied to overview
the structure of a research field and to monitor its evolution. This book contributes to
the development of this application of bibliometric maps.CWTSFSW - CWTS - Ou
