Climate Change Awareness Across Africa (May 18, 2016)

Climate Interactive launched a new effort to expand climate change awareness across Africa. With tools that have helped decision-makers and citizens worldwide, Climate Interactive will be supporting people in leading the World Climate Simulation. At these events, people became "climate negotiators" tasked with agreeing on a global climate agreement to limit climate change. In the last year almost 15,000 people have participated in similar simulations worldwide, and for many it has been transformative in increasing their awareness and understanding of the challenge we face.

This effort was launched in partnership with the new Mohammed VI Polytechnic University (UM6P) in Morocco and relies on the ongoing partnership Climate Interactive has with MIT Sloan School of Management, UML Climate Change Initiative, and others.

Climate Interactive hosted trainings for people interesting in facilitating World Climate Simulation events. Events were held in:
Nairobi, Kenya: May 26-27
Addis Ababa, Ethiopia: June 1
Cape Town, South Africa: Week of June 6

Member Travis Franck, Program Director of Climate Interactive stated, “The System Dynamics chapters and community have been involved from the beginning, and their efforts are important because they are fundamental to organizing these initial events in Africa. Climate Interactive gives special thanks to the two System Dynamics Chapters, Africa Regional and South Africa, for helping launch this Africa-focused project. The meetings in Nairobi and Cape Town could not be done without the support of fellow system dynamicists and their networks.”

Announcing the Publication of Limits Revisited, a Review of the Limits to Growth Debate (May 9, 2016)

A new review of Club of Rome’s landmark publication Limits to Growth was published to coincide with the April 19, 2016 launch of the UK government’s newly established All Party Parliamentary Group on the Limits to Growth. The report Limits Revisited, commissioned by the APPG, was written by the University of Surrey’s Professor Tim Jackson and Robin Webster, a freelance environmental science writer. As stated in the press release, “Limits Revisited traces the history of the Club of Rome’s report and dispels some of the myths surrounding it. It assesses the historical accuracy of the report’s projections and unravels the debates it inspired over the intervening decades. No imminent exhaustion of physical resources is in sight; but production peaks for several key resources are likely within a few decades. Beyond that point, resources will be harder to extract and society will have to divert resources away from productive activities. Limits Revisited also draws attention to certain limits which were all but unforeseen in the 1972 report. It highlights in particular the enormous challenge of meeting the 1.50C climate change target established in the Paris Agreement. It also explores the economic and financial challenges of a ‘secular stagnation’.”

Washington Post article: Systems thinking as a key psychological driver for concern for environment (April 29, 2016)

Scientists now know the psychology behind your worries about the environment,” an article recently published in The Washington Post, focuses on a study authored by Oberlin College psychologist Paul Thibodeau and his colleague Stephen Lezak. The study that was just published in the Journal of Environmental Psychology finds that those with a tendency to engage in systems thinking - embracing complex, multifaceted causal explanations for phenomena and recognizing the unpredictability of how nature works - tend to value the environment more and to be more concerned about climate change. Thibodeau is quoted in the article, “the idea is that it’s encouraging people to think about longer chains of causality, nuanced aspects of a complex system, and how any behavior in that system can have both intended and unintended consequences, and those can be hard to predict.” The full article can be read here.

Climate Interactive Encourages "Multisolving" – the search for systemic solutions (April 29, 2016)

Multisolving is the implementation of strategies that improve health, well-being, social justice and resilience which, in turn, can reduce greenhouse gas emissions and protect the climate. Walkable neighborhoods, for example, can reduce pollution from cars, improve people’s health, and revitalize and connect communities. Climate Interactive encourages the use of FLOWER (the Framework for Long-term, Whole-system, Equity Based Reflection), a visual framework for multisolving that provides users a diagram of the six common types of co-benefits of actions to protect the climate: benefits to health, well-being, and safety; energy industry and mobility; food and water; jobs and assets; resilience to extreme events; and connection to the environment and human communities. Learn more about FLOWER and multisolving here.

Society President Etiënne Rouwette Gave Inaugural Speech: Messy problems: from black and white to color, April 28, 2016 (April 28, 2016)

On Friday, April 22, Etienne Rouwette gave his inaugural speech as the newly appointed Chair, Research and Intervention Methodology, at Nijmegen School of Management, Radboud University. His lecture talked about when there is an issue that is more important, the more likely it is that a group of people is responsible for decision making. It's surprising then to realize that discussing issues in groups has not fundamentally changed over the last centuries. Nowadays we have access to a huge amount of information, more and more stakeholders want to have a voice and complex challenges are all around us. And yet a meeting is still a group of people who talk to one another. It is time to bring the meeting into the 21st century and this lecture tells you how. In particular for complex, messy problems issues it is difficult to obtain an overview and to find a solution that is supported by all stakeholders. Some stakeholders are already in the solution mode: if only everyone would implement the plan that we have come up with, the problem would be solved. Approaches such as these are likely to lead to a deadlock and increased frustration. What works better is to ask each stakeholder for their opinions and to combine these in a coherent view of the issue at hand. For this we need an approach to structure information, so that we increase insight into the relationships between ideas and arrive at a shared understanding. Solutions that are based on this approach do work and will be implemented. This lecture deals with methods that create progress in messy problems.

Etiënne Rouwette is Professor of Research and Intervention Methodology at the Nijmegen School of Management. He focuses on supporting group decision making, using methods such as System Dynamics and group model building, scenario analysis and electronic meeting systems. He is particularly interested in the effect of these methods on communication, attitudes and the behaviour of participants.

Member Gautam N. Yadama’s Study Published in International Journal for Equality in Health (April 27, 2016)

On April 26, 2016, International Journal for Equity in Health published the study “Dynamics of sustained use and abandonment of clean cooking systems: study protocol for community-based system dynamics modeling,” the work of member Gautam N. Yadama, along with colleagues Praveen Kumar and Nishesh Chalise. As stated in the abstract, “More than 3 billion of the world’s population are affected by household air pollution from relying on unprocessed solid fuels for heating and cooking. Household air pollution is harmful to human health, climate, and environment. Sustained uptake and use of cleaner cooking technologies and fuels are proposed as solutions to this problem. In this paper, we present our study protocol aimed at understanding multiple interacting feedback mechanisms involved in the dynamic behavior between social, ecological, and technological systems driving sustained use or abandonment of cleaner cooking technologies among the rural poor in India."

New Analysis Released by Members John Sterman and Andrew Jones Discussed in Online Publication (April 25, 2016)

The article “Paris Agreement Pledges Must Be Strengthened in Next Few Years to Limit Warming to 2°C,” released on April 20, 2016, details the new analysis of the Climate Scoreboard, a project lead by John Sterman of MIT Sloan and Andrew Jones and Ellie Johnston of Climate Interactive. In the article, Dr. John Sterman stated “Paris is a major step. But the current pledges defer the emissions reductions needed to keep warming below 2°C until after 2030. By then, substantial additional fossil fuel infrastructure would be built, only to become stranded assets after 2030 at great cost to the companies that built them and the citizens of the nations who financed them.” Information on the computer simulation used by the Climate Scoreboard is available for public use at

Agriculture & Food SIG, the Society’s Newest Special Interest Group (April 20, 2016)

The newly created Agriculture and Food (A&F) SIG will serve as a focal point for food systems researchers in the System Dynamics community. Albreto Stanislao Atzori and Stefano Armenia, leaders of the A&F SIG and representatives to the Society, envision this SIG to attract interest not only from those in the field of agricultural sciences, but also in a broad range of disciplines, including such areas as food science, rural sociology, veterinary sciences, plant pathology, environmental engineering, public policy, biology and urban planning.

Their proposal states “The dynamics of food systems often have important impacts on the well-being of agriculture producers and consumers, the environment and nutritional outcomes. Given their importance, food systems have been the focus of many policy initiatives, including farm-level support policies, environmental regulations, food safety requirements and price interventions. The proposed SIG will focus on food systems as integrated dynamic systems in which economic, social and biophysical are important elements to enhance our understanding and management.”

Information on joining the Agriculture and Food Special Interest Group is available on our website.

System Dynamics Featured in “Of Wolves And Sheep” Post on Online Publishing Insider (April 20, 2016)

The April 14, 2016 post on Online Publishing Insider, “Of Wolves And Sheep,” by Paolo Gaudiano, discusses the well-known predator-prey Systems Dynamics model. The population dynamics model simulates the relationship between wolves and sheep being the only two animals in existence. The article states “One troubling aspect of predator-prey models is that, in many cases, they are unstable: Under most conditions the populations exhibit feast-to-famine swings, until at some point either the last wolf dies, leading to an explosion in the sheep population, or the wolves eat all the sheep and then they too become extinct, having annihilated their food supply.” Gaudiano talks about the current situation of the growing population and “careless” consumption of resources. The author relates the predator-prey model to another situation, “the Internet was like an immense field. Internet users, like our peaceful sheep, grazed on information: the digital equivalent of nutritious grass…” In conclusion, he writes “Unless greed is put in check, oscillations will continue until eventually one or more of these populations will drive themselves to extinction.”

Professor John Richardson Shares Latest Updates from National University of Singapore (April 14, 2016)

Member John Richardson is a Visiting Professor at Lee Kuan Yew School of Public Policy and Residential College 4, and an Honorary Fellow at Temasek Defence Systems Institute at National University of Singapore. In April, John gave a public lecture to the Graduate Seminar in Defense Technology and Systems of the National University of Singapore's Temasek Defense Systems Institute. In the seminar, titled “Messages from ‘Global Models’ About Interdependence, Sustainable Development and the Future of Our Human Species,” John discussed the models that target exponential growth in population, economic output, consumption of natural resources and pollution as global-scale threats.

On May 3, 2016, students from the Lee Kuan Yew School and other NUS (National University of Singapore) programs presented their original model-based public policy oriented projects. The event recognized the students’ achievements in the challenging class titled “Dynamic Modeling of Public Policy Systems” instructed by John Richardson. Eleven presentations were in four subject-matter areas; Health Care Dynamics, Economic Dynamics, Population Dynamics and Political Dynamics. Final projects, oral and written, provided class members with the opportunity to demonstrate the level of mastery they have attained. They were expected to define a policy relevant problem and craft a dynamic computer simulation model of that problem using the Vensim graphical user interface software. After rigorous validity and robustness testing, the model was used to diagnose the problem and point to accessible and compelling policy recommendations.

In other news, John had also been interviewed by the German Public Broadcaster Westdeutsche Rundfunk in Cologne and Dortmund for the program “Time Signal.” The interviewer, Andrea Kath, had connected with John after having read his System Dynamics book Paradise Poisoned. The 30-minute interview was about the life of Sri Lanka's first woman Prime Minister, Sirimavo Bandaranaike.

New Book: The Dynamic Progress Method: Using Advanced Simulation to Improve Project Planning and Management (April 4, 2016)

This new book by members J. Chris White and Robert M. Sholtes brings the power of advanced simulation techniques into the world of project management. The book summary states “Recent computer-based tools for project planning and management focus on user-friendliness and interconnectivity. However, these programs function on the Critical Path Method, or CPM, which was created in the 1950s. These programs, which involve simplistic models and methods, ignore the fact that the underlying computations on which they function have become woefully inadequate for the complex projects of today.

The product of nearly a decade of work, The Dynamic Progress Method: Using Advanced Simulation to Improve Project Planning and Management provides an overview of the research conducted while illustrating some of the issues with current approaches. It presents the Dynamic Progress Method (DPM), an innovative simulation-based approach to project management. It also includes instructions on how to use the accompanying DPM-based simulation tool pmBLOX to plan, manage, and analyze projects.” To learn more about the book and how to order visit the publisher’s page.

New Article in BMC Geriatrics by Society Members John P. Ansah, David B. Matchar, and Chang Liu (March 24, 2016)

Members John Ansah, David Matchar and Chang Liu along with coauthors Rahul Malhotra, Sean R. Love and Young Do have published the article "Projecting the effects of long-term care policy on the labor market participation of primary informal family caregivers of elderly with disability: insights from a dynamic simulation model" in the journal BMC Geriatrics. The background of this paper states "Using Singapore as a case study, this paper aims to understand the effects of the current long-term care policy and various alternative policy options on the labor market participation of primary informal family caregivers of elderly with disability." A model of the long-term care system in Singapore was developed using System Dynamics methodology. The results show "Under the current long-term care policy, by 2030, 6.9 percent of primary informal family caregivers (0.34 percent of the domestic labor supply) are expected to withdraw from the labor market. Alternative policy options reduce primary informal family caregiver labor market withdrawal; however, the number of workers required to scale up long-term care services is greater than the number of caregivers who can be expected to return to the labor market."

4th Annual System Dynamics Conference, 17-18 November 2016, Stellenbosch, South Africa, Call for Extended Abstracts (March 23, 2016)

South African System Dynamics Chapter (SASD) is hosting their 4th Annual System Dynamics Conference, Facilitating Just Transitions, November 17-18, in Stellenbosch. SASD invites the submission of extended abstracts that entail a diversity of domains, disciplines and stakeholders.

The conference overview states “South Africa has experienced a difficult socio-political-economic transition, and still does, in the face of the many challenges that are characteristic of a developing society. The extreme poor live, ironically, in one of the most carbon-intensive economies, which is based on a “mineral complex.” Thus, one finds the fundamental socio-economic problems of inequality, unemployment, chronic diseases, drug addiction, crime and resource exploitation that remain intact in a democratic space that has made possible countless innovations and changes across multiple other spectrums.”

“Der Meister der Simulation” (March 22, 2016)

On February 22, the “Frankfurter Allgemeine Zeitung,” a leading newspaper in Germany, published an article titled “Der Meister der Simulation” (The Master of Simulation) featuring Jay W. Forrester. It is the second in a series on “computer world creators,” the first article was about Robert M. Metcalfe, "The Master of the Ethernet.”

In this article, after some introductory remarks about the fascination of SimCity and like simulators, it starts with Jay´s life on the farm. As a nine-year-old boy he drove the family´s Model T and very soon was also repairing it, he invented mechanisms for a mowing machine, built an electric fly trap, and electrified the house with a 12 Volt wind mill.

After earning his bachelor degree, Forrester went to MIT, where he met Gordon S. Brown who introduced him to the concepts of servomechanisms and feedback. In 1944 he became the leader of the “Whirlwind” project and turned it from an analogue into a digital machine -- a giant step forward. Ken Olson, the later founder of DEC, worked as Jay’s student. Jay then went on to manage the SAGE project with even far greater computer dimensions and huge energy consumption. Great inventions like the core storage device were results of these activities.

In 1956 Jay Forrester turned away from engineering and focused on management; the fluctuations he observed in management systems were a challenge to him. Industrial Dynamics (1961) was the key publication of this time. Later, while at MIT, he became close to the former mayor of Boston, John F. Collins, and their discussions lead him to writing Urban Dynamics (1969.) In 1971 Forrester's World Dynamics followed, which he originally thought would be of interest to perhaps only 200 researchers in total, but with the Club of Rome and its Limits to Growth (Die Grenzen des Wachstums), it was discussed worldwide. Limits to Growth started the sustainability debate of our days.

The articles concludes with “One has to listen to the nearly one hundred-year-old and still ascetic Forrester, and how he analyzes the hopelessly overcome equilibrium models of economists, to understand the enormous potential of his ideas.” (Apologies for translation inaccuracies.)

SDS Business SIG Webinar Episode 1: Dynamics Business Models (March 8, 2016)

Much has been written about the importance of business models. Business Schools teach whole courses on the topic and consultants urge clients to innovate by changing those business models. But current definitions are ambiguous and qualitative. More seriously, those business model frameworks make? no attempt to quantify anything or show how and why the business actually performs as it does – they are descriptive “statues”, rather than true models. The webinar by Kim Warren, of Strategy Dynamics, that was streamed live on Feb 25, 2016 is available now on YouTube. Kim demonstrates that it is possible to develop working, quantified business models that replicate how a real business (or a part of it) performs over time. This makes many important things possible: new ventures can be bench-tested before real money or people's livelihoods are put at risk; market competition can be managed to the firm's advantage; integrated business plans cutting across functional silos can be tested and shared by everyone; big challenges or initiatives can be rehearsed before they happen; and detailed, time-phased action-plans assembled and continually updated. You may view the one-hour Business Special Interest Group webinar Episode 1 at Dynamic Business Models.

NASPAA Announces the 2016 Student Simulation Competition Winners (March 01, 2016)

The National Network of Schools of Public Policy, Affairs, and Administration (NASPAA) conducted the 2nd Annual Student Simulation Competition in Washington DC on February 27th. This year, the simulation challenge was to create an implementable plan to limit global warming. Using the sophisticated Climate Interactive simulation, built using the System Dynamics method called En-Roads, students from 135 universities across the globe formed regional teams and competed off site. The winning team of 18 students met the morning of the competition at the United Nations University, Maastricht Graduate School of Governance. Congratulations to the Maastricht Team:

(March 23, 2016) This past February, the National Network of Schools of Public Policy, Affairs, and Administration (NASPAA) conducted the 2nd Annual Student Competition which was held in seven regional sites in the United States and in Maastricht, the Netherlands. This event has made quite an impact on those who participated! As students reflect back on their experience, here’s what they are saying:

Lize Duminy posted on the System Dynamics Discussion Forum web page: “The primary expertise I depended on during policy negotiations was the ability to communicate the dynamic structure and causal links of the En-ROADS model to non-technical experts in my team, especially those who came from a non-quantitative background.”

Hugo Herrera posted on the SDForum web page, “… beside the tangible outcome, the experience reminded me about two important facts of System Dynamics: the power of simulations to help decision makers to think systemically and the political dimension of the decision-making process.”

Deepal Doshi gave a detailed account of her experience in a recent blog post. “Having participated in Model United Nations simulations before, I thought I knew what this would be like. However, this was completely different. The preparatory material for the competition was given 48 hours prior to the day of the competition This included the main case, a sector briefing, worksheets and charts for the simulator.… Working under time pressure made the task at hand more difficult.” (See earlier news below titled “NASPAA Announces the 2016 Student Simulation Competition Winners.”)

Extend the Learning of Economics with Dynamic Modeling (February 18, 2016)

At the University of Bergen in Norway, David Wheat and his colleagues at two Ukrainian institutions--the National University of Kyiv-Mohyla Academy and the Ivan Franko Lviv National University--are collaborating on a project called "Extend the Learning of Economics with Dynamic Modeling." Funded by the Norwegian Centre for International Cooperation in Education and the Norwegian Foreign Ministry, the project's primary educational purpose is building dynamic modeling capacity at the Ukrainian universities. The project leaders' strategy is three-fold: train the Ukrainian trainers in Bergen, train on-site in Ukraine, and provide online training to sustain the collaboration in the years ahead. During the four-year project, 40 students and 4 early-career professors from Ukraine will develop System Dynamics modeling skills in Bergen, and gain additional skills to train their colleagues when they return to Ukraine. Traditional on-site classroom courses in System Dynamics will also be developed and will be supplemented by two online courses in economic dynamics. Collaboration between these universities began three years ago, and the new grant provides an opportunity to continue that work and extend it into new areas. For example, Wheat and his Ukrainian colleagues have plans to extend their reach beyond the university classrooms, with workshops planned for economists at the National Bank of Ukraine and with secondary school teachers and students in Kyiv and Lviv. Reviewers called the Norwegian-Ukrainian grant application "very well written" and "of high relevance to the Eurasia program. It is based on a former collaboration and the proposal identifies a great need for the introduction of dynamic modeling tools in education programs of economic analysis."

The New Publication: Factors Influencing the Adoption of Systems Thinking in Primary and Secondary Schools in Switzerland (February 17, 2016)

Authors Patrick Kunz, Ursula Frischknecht-Tobler, Brigitte Bollmann-Zuberbuehler and member Stefan N. Groesser have published a new article in the journal Systems Research and Behavioral Science. The abstract states “Systems thinking is well suited to complement widespread linear thinking in schools. However, previous studies showed that computer modelling can act as a barrier. Therefore, this study focuses on qualitative systems thinking and thus excludes computers as potential barriers. We analyzed factors influencing the implementation of systems thinking in K-9 schools in Switzerland. In our design-based research teachers participated in a standardized training followed by several months of implementation in the classroom….” Please read the early view online version of this research article to see what the results showed.

iSDG Model - Tool for designing SDG strategies and roadmaps (February 9, 2016)

Millennium Institute announced the launch of the Integrated Sustainable Development Goals Planning Model (iSDG). The iSDG model simulates the fundamental trends for SDGs until 2030 under a business-as-usual scenario and supports the analysis of alternative scenarios. It covers all the 17 Goals, and facilitates a better understanding of the interconnections of the goals and targets, in order to develop synergetic strategies to achieve them. The model’s structure can also be expanded to support the analysis of other country-specific development issues beyond the SDGs.

The iSDG model is useful both in the early stages of policy design, to support scenario exploration; and in the advanced stage, when sector-specific interventions can be jointly simulated to assess their combined effect. This enhances the ability of policy makers and planners to evaluate and prioritize projects, investments, and strategies based on anticipated impacts, and to visualize how the combination of interventions lead to positive synergies. For more information and to download the beta version of the model, visit

Fires burning in Tasmania - system collapse? (February 2, 2016)

“This is bigger than us. This is what climate change looks like, this is what scientists have been telling people, this is system collapse,” fire ecologist David Bowman, was quoted in the article Tasmania fires: First images of World Heritage Area devastation emerge, show signs of 'system collapse' on The first images to emerge from within Tasmania's fire-affected World Heritage Area (WHA) have illustrated the level of destruction caused by bushfire, as experts warn such incidents are signs of a changing climate. 11,000 hectares of WHA are incinerated by the Tasmania bushfires. Wildlife, including wallabies and wombats, are also affected and experts say parts of the Central Plateau will not recover.

Public Radio International interviewed member John Sterman (January 27, 2016)

Public Radio International invited member John Sterman to consider whether big oil companies are really on board for addressing climate change. Listen to the discussion about “Can a Norwegian company with 'oil' in its name transform into a wind company?” that aired on the PRI segment “Business, Finance & Economics.” Also on the heels of the December climate summit in Paris, John speaks in praise of electric cars in the PRI news story “What auto companies might look like in a world with less gas . . . and fewer cars.

New Publication by United States Environmental Agency (January 27, 2016)

The paper “A System Dynamics Model for Integrated Decision Making: The Durham-Orange Light Rail Project” has recently been published online at the EPA Science Inventory. The purpose/objective states “The United States Environmental Protection Agency (US EPA) Sustainable and Healthy Communities Research Program (SHC) has committed to developing systems approaches that enable communities to act on an enhanced understanding of these interconnections and to comprehensively account for the full costs and benefits of community decisions in the social, economic, and environmental dimensions. This report documents the development and testing of a System Dynamics (SD) model as a decision support tool for community sustainability with the proposed Durham-Orange Light Rail Project (D-O LRP) in Durham and Orange Counties, North Carolina, as a case-study.” The description of the work includes “In the first phase of this modeling effort, a conceptual model for the D-O LRP was designed with a high degree of input from stakeholders, including representatives from the regional transit authority, county health department, stormwater management department, and city and regional land use and transportation planning departments, among others. This conceptual model served as a framework for the operational SD model, which was built to evaluate a number of policy scenarios, many of which were also suggested by stakeholders. The operational model was subjected to rigorous quality assurance tests, including the sensitivity of the model to assumptions and inputs, and the evaluation of outcomes – social, economic, and environmental – resulting from actions that emanate from or impinge on the D-O LRP.”

New Article in Jacobs Journal of Medicinal Chemistry (January 21, 2016)

The article “Systems Thinking for Medicinal Chemists” by Robert E. Smith, Kevin Tran, and Kristy M. Richards has been published in the Jacobs Journal of Medicinal Chemistry. The article shows an interesting view of the landscape of medicinal chemistry; and its increased use of technology and big data, and government initiatives. The abstract states: “Systems thinking has become an essential part of modern medicinal chemistry and new drug development. It is based on the concepts that complex problems almost always have multiple causes and that there are often connections that have not always been obvious. In contrast to reductionist thinking, systems thinking uses network theory and nonlinear mathematics to prevent, diagnose, treat and even cure diseases. Systems thinking is an integral part of predictive, preventive, personalized and participatory (P4) medicine.”

2016: New System Dynamics Song (January 21, 2016)

"System Dynamics Song: Close The Loop" was originally written and performed in 1976 at Geilo, Norway Conference by a group of attendees who protected their anonymity under the name of the Transient International Consortium at Geilo (TICAG). The song had an encore performance at the 2000 Bergen Conference.

This year, there is a new song: "Looking for Feedback Loops." Below are the artists' stories and photos. Wolfram Reinhard, born on the 6th of June 1990 as Wolfram Pallaske, is a student at the Leibniz University Hannover and is focusing on regional development in his Bachelor’s thesis. In 2009, he graduated high school with music as one of the main courses, but he started learning to play several instruments when he was six. After his brother Georg wouldn't stop bugging him, he recorded and cut the song "Looking for feedback loops", of which Georg wrote the text himself. Wolfram Reinhard has already finished several music related projects, which he was realizing outside of the curricula of his temporary education, alongside which he produced one CD. The strong positive feedback on the song "Looking for feedback loops" surprised the artist.

Georg Pallaske, born on the 4th of October 1987, is a current student in the European Masters Programme in System Dynamics (EMSD). After his Bachelor’s degree in Business Administrations, he entered the EMSD because of the potential the he saw in the application of the method with expert-groups (group-model building). After one and a half years of studying SD, and a lot of conversations with peers and experts, he decided to write a song about SD which compiles the things that are still at odds within the field, and put them into a nice message that comes across easily. And thanks to his little brother the song is available in a version that people might even enjoy listening to. Georg Pallaske is currently in the last semester, and will soon start writing his masters' thesis.

Thanks to Wolfram and Georg!

System Dynamics Article in Risk Analysis (January 18, 2016)

The published article “A Simplified Approach to Risk Assessment Based on System Dynamics: An Industrial Case Study” in the journal Risk Analysis is available electronically. The authors are Emmanuel Garbolino, Jean-Pierre Chery and Franck Guarnieri. The abstract states “Seveso plants are complex sociotechnical systems, which makes it appropriate to support any risk assessment with a model of the system. However, more often than not, this step is only partially addressed, simplified, or avoided in safety reports. At the same time, investigations have shown that the complexity of industrial systems is frequently a factor in accidents, due to interactions between their technical, human, and organizational dimensions. In order to handle both this complexity and changes in the system over time, this article proposes an original and simplified qualitative risk evaluation method based on the System Dynamics theory developed by Forrester in the early 1960s. The methodology supports the development of a dynamic risk assessment framework dedicated to industrial activities. It consists of 10 complementary steps grouped into two main activities: System Dynamics modeling of the sociotechnical system and risk analysis. This System Dynamics risk analysis is applied to a case study of a chemical plant and provides a way to assess the technological and organizational components of safety.”

BLOG: Overcoming the Systemic Challenges of Inequity (January 18, 2016)

Bridgeway Partners started a blog post that describes several dynamics and assumptions that lead inequity to persist, and six high leverage interventions leaders can pursue to create greater equity in their communities. The announcement about the new blog post states “related problems of structural racism and economic inequality undermine the moral as well as social and economic fabrics of our country.” Many of the ideas in this post are drawn from David Peter Stroh's book Systems Thinking for Social Change.

Member Simon Shepherd, and Chandra Balijepalli published a new paper (January 13, 2016)

Member Simon Shepherd, and Chandra Balijepalli published the article “A game of two cities: A toll setting game with experimental results” in the journal Transport Policy. The paper extends the idea of competition between cities by setting up a System Dynamic model of two cities which includes modes such as car, bus, train and walking and cycling. This paper innovates by integrating the simulation of land use transport interactions with a class room style experimental game and analyses the gaming strategies from a continuous repeated prisoner's dilemma involving setting of tolls to maximize the welfare of residents. Highlights of the paper include the development of a twin city land use transport interaction model; the incorporation of gaming facility to explore competition, and analysis of toll setting gaming experiment and use of information over regulation in policy making.

Some other related papers on this topic include “Cordon tolls and competition between cities with symmetric and asymmetric interactions” published in the Journal of Transportation by Chandra Balijepalli and Simon Shepherd and “A review of system dynamics models applied in transportation” by Simon Shepherd published in Transportmetrica B: Transport Dynamics.

System Dynamics Application Used in Investment Research Methods (January 12, 2016)

The FA Online edition of Financial Advisor, on January 12, posted the article “Cucchiaro Launches RIA, Hedge Fund.” Stephen J. Cucchiaro has formed 3EDGE Asset Management, a Boston-based Registered Investment Advisor (RIA) where he will serve as president, CIO and chairman of the investment committee. Parts of the article follow: Cucchiaro, who uses a scientific methodology in his investment strategy, began managing investment portfolios in 1994 and was founder, president and CIO of Windward Investment Management. … Cucchiaro uses proprietary investment research methods, including applications of engineering, System Dynamics and complexity economics concepts to analyze the relationships that drive markets. “Our approach seeks to identify asset classes and geographies that may be undervalued as a result of the macro-inefficiencies inherent in the global markets,” Cucchiaro said. “We are looking to capture the potential for material long-term price appreciation of these undervalued asset classes and geographies over different time frames.”

The firm will apply a multiplayer game theory framework to better understand how policies by actors like central banks might influence the direction of capital markets. “We may be at a critical juncture in the global markets,” Cucchiaro said. “The massive central bank intervention since 2008 has, in many instances, elevated asset prices. In the years ahead, attractive investment returns, particularly on a risk-adjusted basis, could be difficult to achieve as markets may be susceptible to diminishing returns from monetary stimulus. In such an environment, more passive buy and hold strategies could prove to be disappointing, while short-term trading strategies could also be counter-productive since investors may be whipsawed by market volatility.” …

Mr. Cucchiaro gave a plenary presentation at the 2013 Cambridge Conference titled “A System Dynamics Approach to Modeling the Global Capital Markets.”

New Book by Society Member Hassan Qudrat-Ullah (January 11, 2016)

Demonstrating the Utility of SD Modeling for Synthesizing Epidemiologic Evidence to Inform Public Policy (January 07, 2016)

Member David Lounsbury, along with Anton Palma, Nicholas Schlecht and Ilir Agalliu recently published the article “A System Dynamics Model of Serum Prostate-Specific Antigen Screening for Prostate Cancer” in the prestigious American Journal of Epidemiology. The article is available electronically. Their publication adds to the on-going deliberation about the benefits and harms of regular prostate-specific antigen (PSA) screening for adult men. Since 2012, US guidelines have recommended against PSA screening for prostate cancer, which was based mainly on the results of two large clinical trials [i.e., the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening trial and the European Randomized Study of Screening for Prostate Cancer (ERSPC)]. However, evidence of screening benefit from the PLCO and the ERSPC trials has been inconsistent, due partly to differences in participant noncompliance and contamination. In their article the authors describe how they used System Dynamics modeling to replicate the PLCO trial and to extrapolate follow-up to 20 years, correcting for effect attenuation in a three different scenarios. Two of three simulated scenarios showed a benefit of PSA screening, with relative risks of 0.62 (95% confidence interval: 0.53, 0.72) and 0.70 (95% confidence interval: 0.59, 0.83) for cancer-specific mortality after 20 years, demonstrating that after correcting for noncompliance and contamination, there is potential benefit of PSA screening in reducing prostate cancer mortality. This work underscores the utility of System Dynamics modeling for synthesizing epidemiologic evidence to inform public health policy.

Update: XMILE Approved (January 04, 2016)

The XMILE 1.0 was voted and approved as the international technical standard by OASIS on December 14th, a significant achievement. This is the first standard implementation of System Dynamics vocabulary since it was first imagined by Jay Forrester in the 1950s.

XMILE is a standard for representing System Dynamics models using XML and in 2015 version 1.0 was adopted by OASIS (the international standards body). This is an important achievement, but as with any standard, it will benefit from ongoing scrutiny and development by members of the System Dynamics community. The original XMILE Technical Committee chaired by Karim Chichakly and Steve Adler would like to continue work with that broad based input to make that happen. At the 2016 Winter Policy Council meeting President Etiënne Rouwette asked Vice President E-Presence Bob Eberlein and President Elect Leonard Malczynski to find a structure for the Society to support that ongoing development.

What Must We Now Do To Turn Promises Into Policies (December 16, 2015)

WGBH NEWS, Boston, with reporter Jim Braude, aired the interview “Will the COP21 Climate Deal Save the World?” Braude interviewed MIT Sloan School of Management Professor John Sterman and UMass McCormack School of Policy and Global Studies Dean David Cash, both just back from Paris, asking, "Is the COP21 climate deal one which will help save the world? Or is it just a lot of hot air?” Sterman and Cash debated the topic after a recap that included a clip of President Obama, who stated “… We succeeded. We came together around the strong agreement the world needed …” Is that right? Watch and see. Sterman argues that debating whether the agreement is deliverance from climate catastrophe or a dud isn’t the right question. Rather, what must we now do to turn the promises of Paris into policies that cut greenhouse gas emissions? In related news, the Energy and Environment section of The Washington Post published the article by Chris Mooney, “The world just adopted a tough new climate goal. Here’s how hard it will be to meet?” This article references a “telling figure provided by Climate Interactive, showing how current pledges by countries (“INDCs”) take the world off the worst-case path for warming, but also how far they are from the “safe” path of less than 2 degrees C.” And, The Blog at the HUFFPOST GREEN posted the article “The Paris Climate Agreement: Deliverance or Disappointment?” by John Sterman.

Article in "Systems" (December 13, 2015)

Neal Tan and Purba Mukerji, along with member Khalid Saeed, have produced a fascinating analysis of the 2007 US housing market collapse, investigating several accepted causes of the financial crisis and observing model simulation data to understand the validity of these hypotheses. For more, read the article “An Examination of the Influence of Household Financial Decision Making on the US Housing Market Crisis” available through the journal Systems.

Paris Climate Deals (December 08, 2015)

On December 5, 2015 the New York Times quoted member John Sterman in the article In War of the Temperatures, a Cease-Fire of Sorts: “It is dangerous for our leaders to count on emissions cuts that have not been pledged as if they will somehow occur automatically when those cuts require tough negotiations, greater funding and technology transfer for developing nations, and big changes in public opinion. Our leaders must not sugar coat the challenge we face just to paint Paris as a success.” Climate Interactive’s climate scoreboard, reporting the impact of new pledges for emissions reductions, is posted every day, with a daily headline. The breaking news for today, December 8, includes “No changes to the INDCs in the past couple of days. Therefore, if all INDCs now submitted are fully implemented, with no further action, global temperatures are still expected to rise 3.5°C (6.3°F) above preindustrial levels. Canada has surprised many with a call to limit warming to 1.5°C, joining with the most vulnerable nations.” Please visit the website for the full story and daily updates.

Five Prescient Classics That First Made Sustainability A Public Issue (December 07, 2015)

The Limits to Growth: A Report for the Club of Rome's Project on the Predicament of Mankind by Donella H. Meadows, Dennis L. Meadows, Jørgen Randers, and William W. Behrens III is featured as one of “five prescient classics” that helped bring sustainability to the forefront more than four decades ago in an article in the November issue of Nature. “The launch of Spaceship Earth” by Adam Rome reviews the premises of five books, written between 1964 and 1972, that look at the topic of sustainability from different perspectives. This is an interesting read for those who would like to learn more about the evolution of sustainability issues.

Groundbreaking Model of Depression (December 02, 2015)

A scientific study co-authored by Andrea K. Wittenborn and Society member Hazhir Rahmandad “opens the gate” to understanding the myriad drivers of depression. Funded by the National Institute of Mental Health, Michigan State University and MIT scientists developed a comprehensive model of depression, showing how biological, psychological, social and environmental factors overlap and intersect over time. This model is a pioneering tool for personalized treatment of a public health problem that costs the United States over $210 billion every year. Common treatments of psychotherapy and antidepressants are helpful and important, but results vary widely and meaningful improvement is reported by only about half of patients, as discovered through the analysis of nearly 600 scientific articles on depression. A paper detailing the research findings and model is forthcoming in the journal Psychological Medicine. Read more about the topic in the following press release.

The course is interactive with on-line tasks and immediate answers, videos, analogies, animations, simulators, simulation models, and a message service. Earlier students rank highly the course and its innovative teaching methods. The course runs in fall and spring semesters, offers an exam, and there is no tuition fee.

Climate Change Interactive Graphic (November 24, 2015)

The New York Times published an article using Climate Interactive’s analysis on the Paris climate talks. This article is an “interactive graphic” designed for mobile devices (i.e., open it on a phone or tablet and swipe). It is an interesting way to tell the story based on model output. The original video “How Could Paris Talks Ratchet Up To Success?” featuring Drew Jones of Climate Interactive, that was posted earlier was short, but this is even more of an “executive summary” of the pledges to date. Questions and comments sent to Climate Interactive are being addressed on a quick FAQ page for the article here.
