Peer Mentoring Network

David Andersen connects with colleagues via a System Dynamics peer mentoring network, aka The Thursday Morning Group. David says peer mentoring is imperative to increasing effectiveness and progression in careers and professions, specifically in fields such as System Dynamics. The Thursday Morning Group meets via live video chat in order to catch up and provide support for fellow System Dynamicists who are exploring new challenges and project avenues. Participants come from as far west as California and as far east as Ethiopia. Some members have known each other since 1975, and others as recent as several years ago. Attendance is very regular and members of the group are committed to high quality work in System Dynamics and its effect on society. Participants act as the group mediator to ensure effectiveness of the online peer mentoring session. The international group explores and develops aspects of System Dynamics issues, concerns and future planning by rotating who presents research and issues at the meetings. Each meeting has a particular focus and participants prepare questions they would like to address during meeting times. Friendships are strengthened and professional development increases as projects are launched and research continues to be conducted through the System Dynamics Peer Mentoring Network group meetings on Thursday mornings.

Perhaps there are similar efforts elsewhere that the Society can share on our website? If so please send us your news!


Diana Fisher is one of three expert panelists discussing the impact of XMILE

XMILE Panel Disucssion: How Will XMILE Impact the System Dynamics Landscape?

Over the past months, we’ve seen great System Dynamics use cases, ranging from climate to retail, some using Big Data. The goal of XMILE is to make it easier to develop such applications and support the integration of System Dynamics models into additional solutions being developed for business and policy makers. To finish the year, we are presenting four webinars that focus on the draft XMILE specification developed by the OASIS Technical Committee.

In this fourth and last XMILE overview webinar, we will have an open panel discussion with three leaders of the System Dynamics field on their views of what XMILE can do to change the field. Please join Andrew Ford of Washington State University, Diana Fisher of CC Modeling Systems, Ignacio Martinez-Moyano of Argonne National Laboratory, and us for what promises to be an energetic and informative discussion.

This webinar is the twelfth in the Big Data, System Dynamics, and XMILE webinar series jointly sponsored by IBM, isee systems, and the OASIS XMILE Technical Committee. The series showcases exemplar applications of System Dynamics in the areas of environment, business, health care, and public policy and discuss new opportunities that will be available as the XMILE standard is adopted.

If you know people interested in this topic, please tell them about this event. Read details and register. Visit xmile.systemdynamics.org for more information on this event and the full series including past webinar recordings available for viewing, upcoming events, and joint sponsors.

C-ROADS Analysis in Science article

The news item A bold baby step on emissions, by Eli Kintisch from the new issue of Science (6 JUNE 2014 • VOL 344 ISSUE 6188 1071) discusses the likely impact of the new proposed EPA rules limiting CO2 emissions from existing coal plants. The team at Science asked Climate Interactive to analyze the impact of the rules on global emissions and warming.

Opponents of the rules including the coal industry argue that the US rules will have only a small impact on global emissions and warming, but the goal of the rule is also to promote reductions by other nations. Up to now, nations including China (the world’s largest emitter), India, and other key developing nations have argued that they should not be asked to cut their emissions or coal use when the US has no policies to cut theirs. The new rules, if implemented, will undercut this argument, and may be important in leading to a new global agreement to reduce emissions now being negotiated, with a target date for agreement of 2015, at the UNFCCC meeting to be held in Paris that year. The C-ROADS analysis shows that if other nations follow the US reductions the benefits are huge, with future warming falling from nearly 5°C above preindustrial levels to just above 2°C.

Further explanation and documentation of the analysis can be found here. Sent in by John Sterman.


In Memoriam

Klaus Dieter John

Klaus Dieter John from Chemnitz University of Technology passed away two weeks ago. Klaus was a long time member and participant at our conferences every year. In addition to being a past representative of the Economics Chapter, Klaus was an enthusiastic reviewer for conference paper submissions. Klaus introduced his daughter Sarah and son Sebastian to System Dynamics and they accompanied him to a number of our conferences. Sarah wrote recently “My father often told us how much he enjoyed being part of the System Dynamics Society. He really cherished the friendly and warmhearted atmosphere that he hadn’t experienced at any other society in that intensity and manner. I just wanted to let you know, how inspiring the System Dynamics Society had been to him.”

Narendra K Patni

Narendra K Patni from Patni Holdings LLC has died recently. Naren was a steadfast sponsor and member the System Dynamics Society for many years. He was a graduate of MIT Sloan School of Management, Massachusetts Institute of Technology. Naren was a student of Jay Forrester and worked for him for a few years prior to the formation of Patni Computer Systems, an extremely successful Indian outsourcing business. Earlier this year, Naren wrote a quick note to the Society office, “He [Jay] and I go a long way back. He is my true mentor.” Naren introduced his son Anirudh to System Dynamics; Anirudh was also a member of the Society.


Rogelio Oliva wins POM Society’s Skinner Teaching Innovation Award

Executive Editor of the System Dynamics Review and MIT Sloan PhD alum in System Dynamics Rogelio Oliva has been awarded the Skinner Teaching Innovation Award by the Production and Operations Management Society (POMS). Congratulations Rogelio! Below a description of the award and the citation.

The purpose of this award is to recognize impact and innovation in the teaching of Production and Operations Management courses.

Award Criteria:

  1. Pedagogical excellence. This could be documented through the diversity of courses taught and student evaluations, letters of support from former students and/or assessments of knowledgeable colleagues.
  2. Creativity and/or innovation. This would be reflected in teaching approaches and methodologies (e.g., team teaching, student teams, action learning, role playing, etc.) and/or new ways for understanding actual operations problems and the methods that can be applied to deal with them (e.g., frameworks, technology, software, etc.).
  3. Impact. In this case, impact on the field, the profession, students/executives, and managers is of relevance. Various types of evidence could be offered to demonstrate that the applicant’s teaching has influenced the world of POM. Having taught large numbers of students is certainly one measure of impact, but more important is evidence that the applicant’s teaching has influenced behavior. This could be documented via letters from former students, statements from people in industry who have hired former students, and letters from other academics who have themselves been influenced by the applicant’s teaching (e.g., by adopting a book, case or course structure).

Citation: Professor Oliva is truly a master of the case method of teaching. His former students describe his classes as extremely demanding, even stressful, but their appreciation is clear from his consistently school-leading teaching evaluations as well as the remarkable 12 teaching awards that he has received in his 16 years of teaching. Former students consistently comment that Professor Oliva’s classes were transformational for them in the professional journeys. In addition, he has made substantial contributions to our profession through his numerous case method workshops around the world, as well as his widely-adopted Harvard Business School cases and teaching notes.

The list of past winners is at http://www.poms.org/2009/02/teaching_innovation_awards.html#more.

Yukata Takahashi quoted in Japanese newspaper

Society member, Professor Yutaka Takahashi of Senshu University School of Commerce, reported to us that he was recently quoted in the Yomiuri Shimbun morning edition.

At issue was public procurement for a job training program. There are laws in Japan that prohibit public officers having close contact with prospective bidders prior to the bidding process. Despite this, several officers of the Ministry of Health, Labour, and Welfare gave much information to a prospective bidder, the Japan Organization for Employment of the Elderly, Persons with Disabilities and Job Seekers (JEED).

Professor Takahashi credits his System Dynamics experience with aiding him in concluding that even though regulation and punishments are in place for the public procurement process, there are “systematic problems…” He went on to say, “The schedule and nationwide scale of this project caused uncertainty and related organizations’ avoidance of responsibility. The correct solution must redesign the whole project as a system, balance resources and project size, and avoid underestimating unfavorable time evolution of small changes.”

Professor Takahashi is a member of the public procurement supervision committee, Ministry of Health, Labour, and Welfare in Japan.

The Yomiuri Shimbun has a daily circulation of over 9.8 million copies.
