Dr. Moses N. B. Ayiku, a native of Republic of Ghana, West Africa, was at George Mason University as a visiting scholar and adjunct prof, during the time which he and John collaborated on this paper. The article appeared in Journal of Systems & Cybernetics in Management, New Delhi, official journal of Society of Management and Applied Cybernetics (SOMAC), the first Cybernetics society in India. Dr. A. M. Ghosal was the first editor of this journal, I believe.
