International Academy of Astronautics The International Academy of Astronautics (IAA) is a non-governmental organisation of experts committed to expanding the frontiers of space. It was established in Stockholm (Sweden) on August 16, 1960.
Society for Economic Measurement The Society for Economic Measurement, or SEM, is a scientific learned society in the field of economics. It was founded on August 24, 2013 by William A. Barnett in order to "promote research on economic measurement, using advanced tools from economic theory, econometrics, aggregation theory, experimental economics, mathematics, and statistics".. Nobel Laureate James Heckman will take over as the society's second president in 2019 for a three year term in office. The goal of the SEM is to promote in economics--given the constraints of a social science--the implementation of the strict rules of measurement and data gathering standards used in the physical sciences. Carnegie Mellon University, the Center for Financial Stability, and the University of Kansas are sponsors of the society.
