Bornmann and Leydesdorff (2011) proposed methods based on Web of Science data to identify field-specific excellence in cities where highly cited papers were published more frequently than can be expected. Top performers in output are cities in which authors are located who publish a number of...

As research becomes an ever more globalized activity, there is growing interest in national and international comparisons of standards and quality in different countries and regions. A sign for this trend is the increasing interest in rankings of universities according to their research...

Evaluative bibliometrics is concerned with comparing research units by using statistical procedures. According to Williams (2012) an empirical study should be concerned with the substantive and practical significance of the findings as well as the sign and statistical significance of effects. In...

This study shows for eight science-based industries that the citation impact of research collaboration is higher for international collaboration than for national and regional collaboration. A further analysis of institutional affiliations shows that university-industry-government collaborations...

The geography of scientific knowledge is defined as the replication process of locally produced knowledge claims. Proximity in social, cognitive, and physical dimensions promotes the sharing of tacit knowledge. Thus, given the complementarity between tacit and codified knowledge, proximity...

Do-it-yourself biology, as a promise of democratization of science, is analyzed in terms of its spatiality and materiality, and in terms of the various kinds of boundary-work it entails, in the perspective of a geography of science that focuses on emerging and less institutionalized sites of...

Given the recent trend in bibliometrics and information science to use increasingly complex statistical methods, it is necessary to have powerful toolboxes to work with data from Web of Science (Thomson Reuters). We developed such a toolbox with four specific commands for the statistical...

We propose a research program to analyse spatial aspects of the science system. First, we provide a review of scientometric studies that already explicitly take the spatial dimension into account. The review includes studies on (i) the spatial distribution of research and citations, (ii) the...

Brazilian scholarly outputs have had rapid growth that was accompanied by an expansion of domestic research collaboration. In this paper, we identify spatial patterns of research collaboration in Brazil, as well as measure the role of geographical proximity in determining the interaction among...

Scientific collaboration is often perceived as a joint global process that involves researchers worldwide, regardless of their place of work and residence. Globalization of science, in this respect, implies that collaboration among scientists takes place along the lines of common topics and...
