Fifth-year Anniversary of the First SD Class at the Lee Kuan Yew School of Public Policy

To celebrate the fifth-year anniversary of the first module (class) in Dynamic Modeling of Public Policy Systems, at the Lee Kuan Yew School of Public Policy, John Richardson’s students will be giving “final examination” presentations describing their original model-based projects. Presentations are given using the “Pecha Kucha” format (20 slides 20 seconds per slide, 6 min, 40 seconds) first introduced by a community of architects in Japan.  As in recent past years, they will be acknowledging their achievements with presentations to a wider audience, comprising not only National University of Singapore faculty and students, but also members of the wider Singapore Community.  This will also mark the completion of the module by more than 100 students from Singapore, China, India, Japan, Indonesia, Korea, Pakistan and the many other nations that the Lee Kuan Yew School serves. Most students will return to or embark on careers as public policy professionals.

What does the module in the Dynamic Modeling of Public Policy Systems entail? Students are expected to define a policy relevant problem and craft a system dynamics model that addresses it. After rigorous validity and robustness testing, the model is used to diagnose the problem and point to policy recommendations. These must be accessible and compelling to potential clients with no background in dynamic systems modeling. These final oral presentations, backed up with written reports and documentation, provide class members with the opportunity to demonstrate the level of mastery in public policy modeling that they have attained.

Dr. Florian Kapmeier and World Climate Inspire German Students

C-ROADS World Climate computer simulation game was introduced by Dr. Florian Kapmeier to college students in Reutlingen University’s ESB Business School in Baden-Württemberg, Germany. In the game, students were assigned roles as United Nation delegates to negotiate, make decisions, and try to reach an agreement that aims at a minimum rise of the global temperature. According to Dr. Kapmeier, the simulation game is a much more effective way for students to learn that early action is needed compared with traditional lectures. The event was reported by Climate Interactive and a local newspaper Reutlinger General-Anzeiger in Germany.

World Climate Game, developed by Climate Interactive and MIT SD Group, featured in ScienceInsider American Association for the Advancement of Science (AAAS) magazine ScienceInsider published an article about World Climate, a game co-developed by the nonprofit Climate Interactive and the Massachusetts Institute of Technology System Dynamics Group. A colleague of the Group, Juliette Rooney-Varge (Director of Climate Change Initiative at UMass), ran it at the American Geophysical Union meeting in San Francisco this past fall. The game, which simulates international climate change negotiations, was created in 2010. It is to U.N. climate negotiations what Model U.N. is to the real thing: a chance for outsiders to get a glimpse of what it takes to hammer out a consensus on a thorny international issue. After the game, Rooney-Varga gathered the group to debrief. “It wasn’t obvious until we did this exercise just how strong the change needs to be…” said Lev Horodyskyj, an astrobiologist at Arizona State University, Tempe. Organizers said that the goal of the game is to inspire, not terrify. Mitigating climate change is an enormous task, but it’s not impossible; and it won’t be resolved without teamwork. “The key insights are that you need everybody to act,” Rooney-Varga said. “It’s all in.”

NASPAA’s First National Student Simulation Competition Uses a System Dynamics Simulator

Photos taken by George P. Richardson

The National Network of Schools of Public Policy, Affairs, and Administration(NASPAA) conducted its first-ever National Student Simulation Competition, “Creating a Locally-Led ‘Bottom Up’ Reform to the Affordable Care Act” on February 28, 2015. The daylong event brought together about 200 students from 93 NASPAA member graduate schools to five regional locations across the country to analyze the delivery of health care service at the local level. Participants presented their solutions to a national panel of judges. The competition featured ReThink Health Dynamics Model, a System Dynamics simulation model, which enables students to think dynamically and over long time horizons to identify sustainable solutions to health care problems. Participants ran more than 4,400 different simulation runs using a Forio user interface that worked flawlessly. According to Laurel McFarland, NASPAA Executive Director, “This competition demonstrates the tremendous learning opportunities gained by using simulations to immerse students in situations where they are able to immediately see the complexities and systemic aspects of public policy and management challenges.” Bobby Milstein, Director of ReThink Health wrote “It was a thrill to hear the insights from each regional winner about where the real leverage may lie in shaping sound health policy. These teams displayed a mix of curiosity, skill, and moral clarity that bodes well for effective action on this critical national challenge. I was also amazed that students from different schools could instantly work so well together and accomplish so much in a single day. . . . Hopefully, we’ll look back on this as an important landmark both for educational methodology and for the U.S. health reform movement. ”

The Discover magazine posted a new article titled “Does Science Produce Too Many PhD Graduates?” The post reflects on a 2014 paper published in System Research and Behavioral Science by Richard Larson, Navid Ghaffarzadegan, and Yi Xue. The original published paper which is titled “Too Many PhD Graduates or Too Few Academic Job Openings: The Basic Reproductive Number R0 in Academia” analyzes the growth in population of PhDs in academia. A follow-on article by the same group of researchers uncovers structural reasons and systemic flaws of science workforce development in the US.
