Today I talk with prof. John Mingers. He is Professor of Operational Research and Information Systems at Kent Business School, University of Kent. He is an Academician of the Academy of the Social Sciences, and has been an Associate Editor for MIS Quarterly. His research interests include research metrics; the nature of information, meaning and knowledge; the use of systems methodologies in problem situations - multimethodology, and the philosophy of critical realism. Prof. Mingers has published extensively in top journals in the different fields and it is is in top 2% of world scientists in IS and OR field and one of the highest cited British scholars. Thus philosophy does have an impact.
