  Liu, X. ; Kaza, S. ; Zhang, P. ; Chen, H.: Determining inventor status and its effect on knowledge diffusion : a study on nanotechnology literature from China, Russia, and India.
  In: Journal of the American Society for Information Science and Technology. 62(2011) no.6, S.1166-1176.
  
  Abstract: In an increasingly global research landscape, it is important to identify the most prolific researchers in various institutions and their influence on the diffusion of knowledge. Knowledge diffusion within institutions is influenced by not just the status of individual researchers but also the collaborative culture that determines status. There are various methods to measure individual status, but few studies have compared them or explored the possible effects of different cultures on the status measures. In this article, we examine knowledge diffusion within science and technology-oriented research organizations. Using social network analysis metrics to measure individual status in large-scale coauthorship networks, we studied an individual's impact on the recombination of knowledge to produce innovation in nanotechnology. Data from the most productive and high-impact institutions in China (Chinese Academy of Sciences), Russia (Russian Academy of Sciences), and India (Indian Institutes of Technology) were used. We found that boundary-spanning individuals influenced knowledge diffusion in all countries. However, our results also indicate that cultural and institutional differences may influence knowledge diffusion.

  Shiri, A.: Revealing interdisciplinarity in nanoscience and technology queries : a transaction log analysis approach.
  In: Knowledge organization. 38(2011) no.2, S.135-153.
  
  Abstract: The study reported here investigated the search behaviour patterns of nanoscience and nanotechnology searchers as revealed by transaction log analysis of the NANOnetBASE electronic book digital library. This paper examines the patterns and strategies of nano searchers' query formulation and reformulation, then explores the extent of interdisciplinarity in search queries using the INSPEC and Compendex thesauri. The results show certain query formulation patterns associated with searching in an emerging and interdisciplinary area of nanotechnology such as: the use of multiword and compound query terms, extensive use of search terms beginning with the prefix "nano," hyphenated terms, spelling variations, a large number of query reformulations, and the use of acronyms. The results also indicate that 62% of the unique top terms resulting from mapping users' query terms to the INSPEC Classification codes represented two or more disciplines, specifically terms associated with the Classification code "A" representing "physics." The results have implications for information organization and representation, user interface design and federated searching in digital libraries and multi-subject databases.
