Common ground or battlefield? Deconstructing the politics of recognition in Turkey
No full textArticleThis is the author accepted manuscript. The final version is available from Taylor & Francis (Routledge) via the DOI in this record.This article examines the impacts that the embrace of diversity talk has had on identity and ethnic politics in Turkey that has evolved toward a relative and selective recognition. Based on the analysis of the cases of the Laze and Kurdish movements, the article argues that the politics of recognition is built conjointly by an array of actors, at different levels, with different aims, and through their very practices and interactions. The article shows that although the embrace of diversity talk may mark a depolitisation of the ethno-national claims, it still gives room to forms of resistance. These dynamics have shaped a non-coherent, multi-layered, recognition that does not allow the building of a common ground in the country but rather of a battlefield around discursive and policies choices.The author would like to acknowledge the gracious input of the anonymous reviewers, and of Anouck Côrte-Real, Adrian Guelke, Gilles Dorronsoro, and Claire Visier for their comments on the first drafts of this article.

A Simulation-based Analysis of Transition Pathways for the Dutch Electricity System
No full textRecent developments constitute a backdrop of change for the Dutch electricity system. Institutional change driven by liberalization, changing economical competitiveness of the dominant fuels, new technologies, and changing end-user preferences regarding electricity supply are some examples of these developments. In order to analyze the conjoint impact of such developments on the internal dynamics of the electricity system (grid-based and distributed generation), a simulation model is developed. The simulation experiments with the model indicate the continuation of fossil fuel dominance as the energy source, and a shift from natural gas to coal seems likely in the base case. In other cases, it is seen that a transition away from carbonintensive mode requires significant regulatory intervention, since technological developments and ‘greening’ end-users fail to trigger a system-wide transition. Moreover, it is observed that policies for carbon abatement and renewable generation support are intertwined, and may lead to unintended shifts of abatement costs to endusers.Multi Actor SystemsTechnology, Policy and Managemen
Energy Transitions towards Sustainability I: A Staged Exploration of Complexity and Deep Uncertainty
No full textThis paper illustrates the use of Exploratory System Dynamics Modeling and Analysis – a multi-method combining System Dynamics and Exploratory Modeling and Analysis to explore and analyze uncertain dynamic issues and test deep policy robustness. This paper gives an overview of the current state of this multi-method by means of an illustration. The multimethod is applied to the transition of the electricity generation system, more specifically the battle between old and new electricity generation technologies. Starting from a small System Dynamics model about the battle, uncertainties are added to turn it into an exploratory variant which is used as a scenario generator in the multi-method. In a follow-up paper, model and method uncertainties are added and explored by joint consideration of the exploratory model, another (large) System Dynamics model, and an Agent Based model. By reading both papers, the reader is taken step by step from the identification of uncertainties, development of System Dynamics models, transformation of these models into exploratory models by adding uncertainty-related structures and formulations, to the stage-wise exploration of different types of uncertainties – starting with parameter uncertainties, subsequently adding uncertainties related to functions, structures, models, and methods.Multi Actor SystemsTechnology, Policy and Managemen
The Impact of Aggregation Assumptions and Social Network Structure on Diffusion Dynamics
No full textDiffusion problems in general, and innovation diffusion problems in specific, are one of the most frequently revisited issues in system dynamics domain. Although the models used for analyzing specific diffusion problems differ in details, in most cases a set of assumptions is recognized to be common. In this study, we aim to conduct a set of experiments in order to question the validity and potential impact of fundamental assumptions regarding the aggregation and social network structure. First, a generic model focuses on the impact of information dynamics that accompany the diffusion process of an innovation is introduced. The experiments conducted on the aggregate and individual-level versions of the model reveal that the behavior of the system converges to the aggregate model assuming perfect mixing as the network gets denser. Secondly, the change in diffusion levels as a consequence of changing network densities was monotonic. However, direction of change was different for different groups of scenarios tested. In other words, in some cases diffusion level increases as the network gets denser, while in some other cases the opposite is observed.Multi Actor SystemsTechnology, Policy and Managemen
When does it really make a difference? Experimenting with the level of actor-heterogeneity in the context of modeling sociotechnical transitions
No full textThis study constitutes a methodological inquiry in a larger research context on transition dynamics, and it focuses on the issue of actor heterogeneity in modeling such processes. On the one hand heterogeneity at the actor level (i.e. heterogeneity among actor groups, heterogeneity among actors in a particular group, etc.) seems to be a very important source for complexity in the observed dynamics, on the other hand introduction of that heterogeneity into the models has a cost of losing some potential of the models to lead to insight development, since they become hard to comprehend in the detail level needed to incorporate mentioned heterogeneity. Hence, as a sub-topic in our wider research objectives regarding transitions, we conducted an experiment on the potential consequences (i.e. gains and losses) of ignoring or recognizing the actor heterogeneity. Three models of the same historical transition case with different types of actor heterogeneity are used in the experimentation procedure. The conclusions include direct outcomes of the experiments, as well as experience of the authors during the process of constructing these three different models that bring about differing challenges.Technology, Policy and Managemen
Relationship Between C-Reactive Protein to Albumin Ratio and Coronary Collateral Circulation in Patients With Stable Coronary Artery Disease
No full text© The Author(s) 2021.We investigated the relationship between the C-reactive protein (CRP) to albumin ratio (CAR) and coronary collateral circulation (CCC) in stable coronary artery disease (CAD). Patients with stable CAD (n = 354) who underwent coronary angiography for suspected CAD and had a total occlusion ≥1 major coronary artery were included in the study. The participants were divided into 2 groups according to the Rentrop score as satisfactory CCC (Rentrop 2-3) and poor CCC (Rentrop 0-1). Patients who had poor CCC had a higher CRP, neutrophil/lymphocyte ratio (NLR), and CAR levels compared with those who had satisfactory CCC (P <.001, P =.046, P <.001, respectively). The CAR (odds ratio: 3.522, 95% CI: 2.515-4.932, P <.001), CRP, NLR, and diabetes mellitus were independent predictors of poor CCC. In receiver operator characteristic curve (ROC) analysis, the optimal cutoff value of CAR to predict poor CCC was 1.27 (area under ROC curve = 0.735 [95% CI: 0.667-0.803], P <.001). A raised CAR may be an independent predictor of poor CCC
Hop, Step, Step and Jump: Towards Real-World Complexity @ Delft University of Technology
No full textThis paper deals with System Dynamics education at Delft University of Technology, the Netherlands. It focuses more specifically on the quadruple jump approach towards dealing with real-world dynamic complexity. The paper starts with an overview of the System Dynamics courses, situated within the broader curriculum. Then recent innovations in the Introductory System Dynamics course are discussed. Finally, some of the lessons learned are distilled. The rationale behind this paper are the beliefs that (higher) education determines to a large extent the quality of (the next generation) professional System Dynamics modellers, and hence, the field of System Dynamics as a whole, and that sharing (innovative and/or proven) educational practices, and exchanging actual and challenging (teaching and testing) cases may lead to further improving the quality of System Dynamics education.Multi Actor SystemsTechnology, Policy and Managemen
Essential Skills for System Dynamics Practitioners: A Delft University of Technology Perspective
No full textThere is little consensus on the skills set required of a system dynamics practitioner. In this paper we use the teaching approach and learning goals of the system dynamics courses at the Delft University of Technology as a starting point to explore the development of system dynamics modeling skills. System dynamics is embedded in the curriculum of students at the Faculty of Technology, Policy and Management (TPM) of the Delft University of Technology. The staged approach by which real world complexity is introduced in the system dynamics curriculum is first explained and the learning goals of the system dynamics education at TPM are described. The role of the quadruple jump approach to system dynamics education in achieving the learning goals of the curriculum is then illustrated using the case of urban dynamics. Finally, we compare the results of the teaching approach, as exemplified in the learning goals, with the skills needed by system dynamics modelers as derived from literature. We conclude that the question of which skills can be taught and which need to be learnt in (professional) practice remains open.Multi Actor SystemsTechnology, Policy and Managemen
