Ljubljana, Slovenia’s lovely capital is one of my favorite places on the planet. So I was utterly delighted to be made an Honorary Senator of the University of Ljubljana on December 3, 2004. I was so pleased that I was willing to wear my only suit and even a tie — as a couple of photographs of the ceremony reveal. Having visited the university and the country many times, they have a special place in my heart. I continue to work closely with Vladimir Batagelj and Anuška Ferligoj on our generalized blockmodeling project, one that draws us ever closer together.
I was privileged to spend half a year at the London School of Economics and Political Science as a Centennial Professor at their (then) Interdisciplinary Institute of Management in 2002. While there I had the time to work on what became a paper (Actor Utilities and Social Network Evolution) that was very important to me. It was generated by a puzzle created by my late colleague and close friend, Norm Hummon. I feel privileged to have had the opportunity of working with Norm while remaining sorrowful for his death, one that came way too early. My stay was made more special by the opportunity to discuss many issues about social research with Peter Abell, usually with an espresso or glass of wine.
I was the elected chair of the Mathematical Sociology Section of the American Sociological Association for 2001-2002. I was the keynote speaker for the International Social Networks Conference (joint Sunbelt XV and 4th European Social Network Conference) on July 6, 1995 in London. I greatly appreciate the invitation extended to me by the conference organizers Martin Everett and Keith Ronnolls. And in what seems another time and galaxy, I was a Gast Professor at the Institute of Advanced Studies in Vienna in 1974.
