9. The 2007 International Conference of the System Dynamics Society (Boston) 29Jul-2Aug 2007 Warren W. Tignor SAIC wtignor@ieee.org 9 Conclusions Majority of SD relevant topics focus on Management, Social Sciences, Mathematical Methods, Operations Research & Management Science, and Environmental Sciences. Emerging topics include Mechanical Engineering, Civil Engineering, Chemical Engineering, Energy & Fuels, Biology, Transportation Science & Technology, Marine & Freshwater Biology, and Computer Science, Cybernetics. Majority of SD articles originate in western society, 39% from the USA and 10% from the UK. There is publication representation from around the world, but plenty of room for others to assume a larger authorship role. SD publishers of choice are a familiar few such as the System Dynamics Review, Journal of the Operational Research Society, and European Journal of Operations Research. There is a publisher for almost any topic of interest, e.g., Annals of Allergy, Asthma & Immunology to Zoo Biology.

10. The 2007 International Conference of the System Dynamics Society (Boston) 29Jul-2Aug 2007 Warren W. Tignor SAIC wtignor@ieee.org 10 Next Steps Need to continue to track the scope and breadth of the SD domain of influence. Determine the robustness of the search query used herein. Establish a set point for the date range of the data repository to control impact of new data entries on results. Track publication date and the electronic availability date.
