Presentation at World Affairs Council of Albuquerque, and at Sandia Natl Lab.

Aug. 13, 2019

    Much thanks to the Albuquerque’s World Affairs Council for inviting me to speak and for the hospitality. Also, while I was in NM, I was asked to present a seminar to the Strategic Futures unit at Sandia National Laboratories. The presentation slides (in .pdf form) can be accessed here.

Guest Lecture: Florida International University

The PowerPoint slides for my guest lecture in Prof. Shlomi Dinar’s class in FIU’s Masters of Arts in Global Affairs Program are posted here. Please browse this website for more information on the age-structural theory of state behavior and visit my pages on the New Security Beat blog for short essays which employ this theory. A brief article (blog) that sums up the findings is: “The Eight Rules of Political Demography” (July 2017).

Lecture: US Army Future Studies Group

At the following links, please find the PowerPoint slides presented and the handout provided at the AFSG lecture session on March 7, 2019. Thanks for the invite, AFSG. Your questions were excellent–probably the most perceptive set I’ve ever fielded (or tried to field).

If you would like to look at some of the theory/applied studies, please cruise through the menus on this website, and read a few of the short essays on political demography (2-3 pagers) on the Wilson Center’s New Security Beat.


Guest Lecture: GMU/Govt444

The PowerPoint slides that were presented in my lecture in Prof. Jack Goldstone’s GOVT444 class at GMU on Feb. 27, 2019 (James Buchanan Bldg., noon) are posted here. If you attended the class, thank you for your attention and questions.

If, by any chance, you would like to know more about the predictions of the age-structural theory, continue reading the posts on this site and the essays organized by the menu. In addition, see the latest posts on political demography on the New Security Beat. They’re quick reading.
