Abstract. The Ranking Web of World Repositories (http://repositories.webometrics.info) is introduced. The objective is to promote Open access initiatives (OAI) supporting the use of repositories for scientific evaluation purposes. A set of metrics based on web presence, impact and usage is discussed. The Ranking is built on indicators obtained from web search engines following a model close to the Impact Factor one.

Abstract. This article explores the concentration in the global plant molecular life science research output. In the past 15 years, especially the share of articles which refer to the model organism A. thaliana has increased rapidly. Citation analyses show an even greater rise in the importance of this organism. Attempts are discussed to come to a scientometric definition of model organisms. For this purpose a comparison is made with applied microbiology. However, few shared scientometric characteristics were found which could help characterise model organisms.

Abstract. The analysis of university-industry cooperation (UIC) rarely considers the geographic implications of its promotion. We hypothesise that UIC may lead to a cumulative advantage of already good performers. The 6th EU R&D Framework Programme is a useful source to verify this hypothesis because of its a priori neutrality regarding UIC. Using original data on the funding allotted per participant, we build national indicators of the value of FP6-sponsored UIC across the EU27.

Abstract. Since the 1980s Spain has developed an ambitious road building programme with the construction of approximately 12,000 km of new motorways. This article analyses the factors related to the placement of these new motorways during two distinct planning periods from 1983 to 1993 and 1994 to 2004. Motorway placement strongly followed the existing radial road network dating back as far as the eighteenth century which illustrates the critical role that past decisions play in the placement of new investment.

Abstract. In order to re-categorize the SCImago Journal & Country Rank (SJR) journals based on Scopus, as well as improve the SJR subject classification scheme, an iterative process built upon reference analysis of citing journals was designed. The first step entailed construction of a matrix containing citing journals and cited categories obtained through the aggregation of cited journals.

Abstract. This paper presents an analytical framework for the comparative analysis of National Research Systems. We follow evolutionary accounts of the research system in combination with insights from functionalist economics of innovation and organisational theorists. We also illustrate the potential use of this framework by applying it to an analysis of the Chinese research system's transformation between 1980 and 2005. During this period, this system is considered to have gradually changed from a centrally planned system to a mixed model.

Abstract. In the last decade, preimplantation genetic testing (preimplantation genetic diagnosis [PGD] and preimplantation genetic screening [PGS]) have become widely used and in 2005 constituted 5 percent of all in vitro fertilization (IVF) cycles performed in Europe. Their diffusion, however, is not homogenous; while in some countries they are prohibited and in others hardly implemented, Spain performs 33 percent of all the PGD/PGS.

Abstract. Access to public knowledge is a prerequisite for the good functioning of developed economies. Universities strive and are also requested to contribute to this knowledge both locally and internationally. Traditional studies on the geography of knowledge flows have identified a localisation effect; however, these studies do not use the country as the unit of observation and hence do not explore national patterns.

Abstract. This study combines Web usage mining, Web link analysis, and bibliometric methods for analyzing research activities in research organizations. It uses visits to the Expert Protein Analysis System (ExPASy) server—a virtual research infrastructure for bioinformatics—as a proxy for measuring bioinformatic research activity.
