System Dynamics Review EARLY VIEW - "Do you bend or break? System dynamics in resilience planning for food security"

Click here for early access

"This paper discusses our experience in using system dynamics to facilitate resilience planning for food security in rural communities that are exposed to ever‐increasing climatic pressures in Guatemala. The social–ecological systems literature is rich in examples where policies to enhance resilience are deduced from factors generally accepted to be present in resilient systems (e.g. redundancy, connectivity and polycentrism). This deductive approach risks being overly simplistic. As an alternative, this paper explores how insights from analysing the structure–behaviour relationship of complex dynamic systems can be used to generate tailored policies. The results show that stability in food systems is mainly driven by key strategic resources that moderate the effects of environmental changes on food availability and affordability. Moreover, our experience highlights the importance of analysing mechanisms that determine a system's behaviour while and after the system is affected by a disturbance to formulate effective resilience policies."

The authors are Hugo Jose and Society President, Birgit Kopainsky.


CALL FOR PAPERS - Special Issue of System Dynamics Review - Bio-Medical Modeling

Guest Editors: Jim Duggan (National University of Ireland Galway), Niyousha Hosseinichimeh (Virginia Tech), Özge Karanfil (Koç University)

The application of system dynamics to health and medical issues has increased substantially over the past decades. Recent advances in computing powers, calibration methods, and data availability made it possible to develop disaggregated models in addition to aggregate models, and it has created new opportunities for modelers to tackle complex and pressing medical issues.

For this special issue, we seek articles that focus on bio-medical modeling. This encompasses a wide range of applications such as modeling physiological problems (e.g., human energy regulation, HPA axis dynamics), chronic diseases (e.g., diabetes, cancer, kidney and, cardiovascular diseases) and infectious diseases (e.g., Polio, HIV). Application areas may vary from modeling of immunodynamics, pharmacokinetics, antimicrobial resistance, addiction physiology, weight dynamics, body fluid electrolytes, food borne pathogens, and chronic disease progression, to pain management, sleep disorders or stress response. We are receptive to both aggregate population-level and individual-level modeling (agent-based modeling).

Inquiries about proposed papers are welcome; the guest editors will provide feedback on proposals. A 2-stage procedure will be followed: Initially authors are requested to submit by email an extended abstract (3 pages maximum). These will be reviewed by the editors and selected authors will be invited to submit a full paper, which will go through standard double-blind peer review. Papers should follow the journal’s reporting guidelines for main articles and other categories of contribution. Inquiries and extended abstracts should be directed to the editors for the special issue, Jim Duggan ([email protected]), Niyousha Hosseinichimeh ([email protected]), Özge Karanfil ([email protected]). Final papers should be transmitted via
the online submission system. 

Timetable: Extended abstracts due February 16th 2020,
Full Paper deadline: May 31st 2020.

Special theme in System Dynamics at the European Transport Conference: October 9 – 11th 2020, Milan, Italy (January 9)

Simulation models are well established in transport-related research, with system dynamics (SD) being increasingly utilised. Transport systems and policies are complex, involving multiple agents or stakeholders, and there are many different feedbacks involved with different time lags between responses of users, developers, operators and policy makers. SD not only offers a different perspective to transport planning but also can demonstrate to policy makers the importance of these feedbacks and lagged responses. Further to this, SD also offers specialised tools and approaches for hybridisation with other simulation techniques, which aid in the understanding of the whole underlying system, calibration of models, optimisation of policies and ease of use through flight simulators. 

Abstracts are now invited which demonstrate the success of system dynamics in transport related research. Innovative approaches and cross-fertilisation with alternative forms of modelling/impact assessment tools, or new and emerging forms of data are encouraged. Topics can cover any aspect of transportation, such as:

  • Freight and logistics,
  • Development of new technologies or business models,
  • Smart transportation systems,
  • Reduction of transport's carbon footprint,
  • Transport and urban planning policies,
  • Performance measurement in transport operations,
  • Stakeholder engagement in transportation governance,
  • Transport and health,
  • Sustainable and equitable policy analysis.

Important notice:
If you submit an abstract, this will go through a selection process. Each year we receive more abstracts than can be accommodated in the programme. If your abstract is selected, please be aware that others have been rejected, that the ETC organisation has invested time in devising an attractive and coherent programme and that delegates have used this programme to decide to come to the conference.

Before submitting your abstract, please make sure there is time and funding to have at least one of the authors come to the conference to present the paper and that you have/will obtain the approval needed (from management or client) to present the work in public at the time of the conference.

We do understand that sometimes circumstances change, forcing authors to withdraw. You would help us by informing us as soon as possible, preferable ample time before the conference. Last minute withdrawals or no-shows negatively affect the conference experience of your fellow transport professionals. If you need any assistance, please contact Sally Scarlett: [email protected]

Call for Papers - Special Issue of Mind & Society on Advanced Modelling of Organizational Behaviour (December 18)

Over the last decades, psychological research has often highlighted that the theory of “rational” decision-making eventually prescribes choices from which humans systematically deviate. Remarkably, several Nobel laureates including Herbert Simon (1978), Daniel Kahneman (2002) and Richard Thaler (2017) have been prized for developing more realistic theories of human behavior and interaction.

In line with these theoretical developments, novel modelling methods have been proposed that allow more realistic descriptions of actual organizational behaviour. In particular, computational methods and statistical techniques allow nowadays to capture dynamics of latent psychological constructs and reproduce the emergence of novel organizational features. Ideally, these methods strive for recreating the complexity of macroscopic organizational structures without losing sight of individual human behavior.

The present call for special issue aims to collect a series of contributions (including original research articles, reports, or reviews) where such methods are employed in order to capture organizational dynamics. Potential methods to be applied to organizational studies include, but are not limited, to the following list: Agent-based modeling, Latent Class Growth Analysis, Hidden Markov chains, Pattern analysis, Nonlinear dynamical processes, Network analysis, Nonlinear regression, Growth curve modeling, Recurrence quantification analysis.

Society Member JD Caddell, of the U.S. Military Academy, is featured in an article highlighting his research, "Using system dynamics to set strategic priorities to address human trafficking." (December 12)

"Many non-governmental organizations (NGOs) work to reduce human trafficking but often fail to understand the context and environment before taking action, resulting in ineffective and sometimes detrimental policies. JD Caddell, U.S. Military Academy, studied how girls were lured and trafficked by reframing the situation as a supply chain and looking at both supply and demand.

"Caddell's study, 'Using system dynamics to set strategic priorities to address human trafficking,' revealed that NGO's actions aimed solely at removing girls from the system yields few long-term benefits and creates more victims in the long run while raid and rescue operations only yields short-term gains."

Society member Dr. Benjamin Chang-Kwon Chung featured in article in The Korea Times (December 10)

Dr. Benjamin Chang-Kwon Chung is featured in an article in The Korea Times where he discusses climate change.

'"Climate change is connected to politics, business, societal conflicts and inter-generational conflicts. It is the result of the most complex system and it is very hard to understand."

The games demonstrate difficulties in making decisions and communication among members of society.

"The games have two lessons: "One should not blame others, rather examine the structure that makes inevitable behavior. Another is (to realize) that today's problem comes from yesterday's solution," Chung said.'
