Show moreBibliometric 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. Show less

Show moreRockets or launch vehicles, though sharing the same technology, have both military and civil applications: they can be used as missiles or as 'ordinary' transportation vehicles. As a consequence, national security and foreign policy considerations stand in the way of the international launch industry becoming a normal service industry subject to free trade (GATS) principles. This dissertation discusses this conflict between national security and trade interests and the way it affects the United States launch trade relations with China, Russia and Europe. It also analyzes the extent to which the respective U.S. laws, policies and practices, in particular those relating to the export of satellites and launchers, restrict the development of these and other countries' commercial launch activities, and it reviews the prospects for a - GATS or space law-based - liberalization of the international trade in launch services.
