Our colleague Calestous Juma—who passed away on December 15 at age 64 after a long illness—was a pioneering, prolific, and influential scholar/practitioner in science and technology policy for sustainable well-being. He joined Harvard Kennedy School (HKS) in 1999 as Director of the Science, Technology, and Innovation Project (a joint venture of the Belfer Center for Science and International Affairs and the Center for International Development) and became Professor of the Practice of International Development in 2002, a position in which he maintained his exceptional productivity and engagement with policy, despite illness, up to the time of his death.

Several developing countries seek to build knowledge-based economies by attempting to expand scientific research capabilities. Characterizing the state and direction of progress in this arena is challenging but important. In this article, the authors employ three metrics: a classical metric of productivity (publications per person), an adapted metric which we denote as Revealed Scientific Advantage (developed from work used to compare publications in scientific fields among countries) to characterize disciplinary specialty, and a new metric, scientific indigeneity (defined as the ratio of publications with domestic corresponding authors) to characterize the locus of scientific activity that also serves as a partial proxy for local absorptive capacity.
