This study explores the impact of social capital on innovation by constructing a more general measure of social capital, which consists of generalized and institutional trust, associational activities and civic norms. We test the hypothesis that social capital has a positive impact on innovation at the national level. After controlling for research and development expenditure and human capital, we find that there is a positive relationship between social capital and innovation. Social capital interacts with entrepreneurship; the strongest relationship is between associated activities and entrepreneurship. This study supports the need to build strong social relationships in today's networked economy.

This study seeks to examine the impact of alumni connections between the evaluators and evaluatees on the results of peer review ratings for the Korean national R&D project and selection success rate. Specifically, this study analyzed the evaluation results of 8,402 research proposal entries submitted between 2007 and 2011 for the “general researchers support project,” all in the Natural Science and Engineering areas and sponsored by the National Research Foundation of Korea. Each proposal entry was evaluated by three evaluators, and approximately 39 percent of the proposals had at least one evaluator from the same university. The results of this study showed that evaluators have a tendency to give relatively high scores to research proposals submitted by the alumni of the same universities as their alma mater. Also, when an evaluator from the same university as an evaluatee was included in the evaluator group, the results of this study showed that the percentage of entry submissions was higher compared to the contrary. Such results show that in the process of peer review–based research proposal evaluations for national R&D projects, alumni connections have significant influence on evaluation results in South Korea.

This study seeks insight into the social structure of Antarctic research from 1998 to 2015 by examining peer-reviewed journal articles listed in the Science Citation Index of the Web of Science database. This study identifies leading countries in peer-reviewed journal article output and applies social network analysis methods to identify countries where authors are collaborating with those affiliated with organizations in different countries. The results show that the number of publications on Antarctica and the proportion of international research collaboration increased from 23.0 to 33.2% during the period of time being considered. The number of articles published by authors affiliated with institutions in emerging countries such as China, Turkey, Brazil and South Korea rose, whereas the proportion of articles published by authors affiliated with institutions in the United States decreased. The largest proportion of academic publications pertaining to Antarctic research was within the natural sciences. Within this broad field, the majority of publications fell within Earth and related environmental sciences and the biological sciences. Social network analysis shows that Antarctic research moved towards a network, in which researchers are internationally more connected than ever before, with countries such as the United States, the United Kingdom, Germany, France and Australia in central positions. Sweden, Belgium and the Netherlands did not account for a high percentage of academic contributions but were still notable for their multinational collaborative research.
