After a review of developments in the quantitative study of science, particularly since the early 1970s, I focus on two current main lines of ‘measuring science’ based on bibliometric analysis. With the developments in the Leiden group as an example of daily practice, the measurement of research performance and, particularly, the importance of indicator standardisation are discussed, including aspects...
In this chapter we review and discuss the potential and limitations of econometric methods for the evaluation of productivity of scientific and technological (S&T) systems. We examine and compare the main approaches that have been applied in the literature: the production function and the production frontier approach. Both approaches present advantages and disadvantages. In the first part of the...
The purpose of this chapter is to present a survey of the development of Science and Technology (S&T) indicators and their use in national policy making as well as to provide evidence of the vulnerability of S&T indicators to manipulation. A brief history of the development of S&T indicators begins with the United States followed by their worldwide diffusion, with particular emphasis on...
The chapter outlines the basics of journal gatekeeping and stresses the gatekeeping indicators initiated by us in the 1980s for the evaluation of the research performance of nations in all fields of science. The results have proven that these indicators correlate well with science indicators built on journal paper productivity and citations of nations and represent implicitly a component of quality...
This paper suggests that an understanding of the changing science-technology-innovation régime can provide a new role for necessarily imperfect S&T indicators. It is argued that it is precisely to the extent which they are questionable that S&T indicators can fulfil their role as mediator and S&T arena decision making instruments. Such a role of S&T indicators is highlighted by initiatives...
This chapter examines the evolution of technological opportunities historically. The disciplinary approach is evolutionary economics combined with patent statistics. By analysing the complexities behind changing technological opportunities, technological paradigms governing the evolutionary process of change are traced empirically. Evidence shows how the path-dependent evolution of technological opportunities...
Scientists in developing countries have access to only a tiny fraction of the information they need, and their own contribution to science is hardly noticed by others. It is important that these countries strengthen their scientific research and that their scientists become fully integrated members of the worldwide network of science. But, unfortunately, the transformations effected in the conduct...
