- Abstract
- Using a database of 1.4 million papers indexed by Web of Science, we examined the global trends in publication inequality and international collaboration in physics. The publication output and citations received by authors hosted in each country were taken into account. Although inequality decreased over time, further progress toward equality has somewhat abated in recent years. The skewedness of the global distribution in publication output was shown to be correlated with article impact, that is, the inequality is more significant in articles of higher impact. It was also observed that, despite the trend toward more equalitarian distribution, scholarly participation in physics is still determined by a select group. Particularly noteworthy has been China's rapid growth in publication outputs and a gradual improvement in its impact. Finally, the data also suggested regional differences in scientific collaboration. A distinctively high concentration of transnational collaboration and publication performance was found among EU countries.

- Abstract
- The counting of papers and citations is fundamental to the assessment of research productivity and impact. In an age of increasing scientific collaboration across national borders, the counting of papers produced by collaboration between multiple countries, and citations of such papers, raises concerns in country-level research evaluation. In this study, we compared the number counts and country ranks resulting from five different counting methods. We also observed inflation depending on the method used. Using the 1989 to 2008 physics papers indexed in ISI's Web of Science as our sample, we analyzed the counting results in terms of paper count (research productivity) as well as citation count and citation-paper ratio (CP ratio) based evaluation (research impact). The results show that at the country-level assessment, the selection of counting method had only minor influence on the number counts and country rankings in each assessment. However, the influences of counting methods varied between paper count, citation count, and CP ratio based evaluation. The findings also suggest that the popular counting method (whole counting) that gives each collaborating country one full credit may not be the best counting method. Straight counting that accredits only the first or the corresponding author or fractional counting that accredits each collaborator with partial and weighted credit might be the better choices.

- Abstract
- This study examines whether an institution's research resources affect its centrality and relationships in international collaboration among 606 astronomical institutions worldwide. The findings support our theoretical hypotheses that an institution's research resources are positively related to its central position in the network. Astronomical institutions with superior resources, such as being equipped with international observational facilities and having substantial research manpower, tend to have more foreign partners (high degree centrality) and play an influential role (high betweenness centrality) in the international collaboration network. An institution becomes more and more active in international collaborations as its research population expands. In terms of the relationship, which is captured by an actor institution's co-authorship preference for each partner in the network, the effect of research resources is not as significant as expected. We found that astronomical institutions are not necessarily preferentially co-authoring with partners that have better research resources. In addition, this study indicates that geographic closeness (or "geographic proximity") largely affects the occurrence of international collaboration. The investigated institutions apparently prefer partners from neighboring countries. This finding gives an indication of the phenomenon of "regional homophily" in the international collaboration network.
