Cornelis Johannes van Dijkum is a Dutch sociologist, consultant and academic at the Utrecht University, known for his contributions in the field of methodology for complex societal problems.
Biography
Van Dijkum obtained his MSc in Physics from the University of Amsterdam in the 1970s, and in 1988 his PhD in Social Sciences from the Utrecht University with the thesis entitled "Paradoxen : een methodologische studie naar vicieuze cirkels in denken en handelen". After his graduation Van Dijkum had started his academic career at the Utrecht University, where he became Professor at the Department of Methodology and Statistics. He has been director of the NOSMO for about a decades. In 2000 he also founded Sokrates Consultancy and Engineering. Van Dijkum was also Editor-in-Chief of the International Scientific Journal of Methods and Models of Complexity journal. Van Dijkum's research interests are in the field of "nonlinear modeling, computer simulation, methodology, epistemology of science, and action research health care."
Work
NOSMO
The Dutch Organization for Methodological Research in the Social Sciences started in the early 1980s as Stichting Nederlandse Organisatie voor Sociaal-Wetenschappelijk Methodologisch Onderzoek. Their initial focus was on qualitative research. Over the years working groups were created around the following subjects:
Notable academics who cooperated in NOSMO beside Van Dijkum were Gerhard van de Bunt, Dorien DeTombe, Stasja Draisma, Frans van Eijnatten, Henk Flap, Joop Hox, Edith de Leeuw, Cora Maas, Gerty Lensvelt-Mulders, Han Oud, Tom Snijders and Fred Wester. One of the offspring of NOSMO is the KWALON platform for qualitative research, and the journals Journal for the improvement of methodology in applied research and International Scientific Journal of Methods and Models of Complexity.
Complexity science
In his 2013 speech on the EURO Mini-Conference Graz 2013, entitled "Complexity is more than complicated," Van Dijkum stipulated that:
... social scientists realized in the last decennia, inspired by colleagues in the natural sciences, that many phenomena in the social world can be viewed as complex social systems.
And furthermore:
Through systems theory one recognizes that events are interrelated, interact with each other and make up systems. With dynamic systems theory one understand that social systems evolve in time, moved by cause-effect relations between events that can be described mathematically in differential equations."
Van Dijkum believed that "with the idea of ‘complex social systems’ one comprehend that those differential equations are non linear, reflecting systems that are difficult to follow and predict, just as many phenomena in the world. It is the start of a promising program of research in the social sciences including system dynamics."
