CSH Workshop "Theory of sample space reducing and expanding processes"
Organized by Stefan Thurner and Henrik Jensen.
Systems and processes with sample spaces or phase spaces that are not constant, but change over time, seem to be at the heart of many complex systems. Yet the mathematical structures behind these processes are practically unexplored. The workshop aims to clarify the situation where we stand with our current understanding, if the current approaches that have been explored by the various groups can be unified, and where to go in terms of possibilities of further fundamental understanding of these processes and their statistics.

Saadi Lahlou: "Installation theory: The analysis of channeled behaviour in large-scale societies"
Join us for a talk by Saadi Lahlou titled "Installation theory: The analysis of channeled behaviour in large-scale societies" on Tuesday, October 24, at 10:00am at the Hub in Room 101.
Abstract: In large-scale societies, individual behaviour is channeled in most mundane activities, and this channeling is more powerful than most “classic” variables as a predictor of behaviour. E.g. in a bus, all passengers behave as “bus passengers” whatever their age, gender, socio-economic status, and even whatever the final reason for their travel. That channeling is indispensable for smooth operation of our complex societal systems. Installation theory provides a robust framework to analyse how this channeling takes place. It provides an operational model of the three layers of components that channel behaviour, with techniques to capture these layers and redesign them to modify behaviour. The theory is grounded in two decades of observation with digital ethnography and experiments in very diverse fields, from homes and offices to hospitals and nuclear plants. The talk will demonstrate the techniques used (based on capture of activity with wearable miniature video-cameras and cued-access to episodic memory), provide the threefold structure of “installations” and show how installations support societal endurance and evolution through distributed, subsidiary scaffolding and enforcement of “appropriate” practice.
Professor Saadi Lahlou is chair in Psychology at the London School of Economics and Political Science.
Wie komplex ist die Wirklichkeit?
Was Wahlmanipulation, Epidemien und die Finanzmärkte gemeinsam haben.
Heutzutage spricht man schnell davon, dass die Fragestellungen unserer Zeit immer „komplexer“ werden. Aber was bedeutet das überhaupt? Verstehen wir die Daten, die bereits an vielen Stellen erhoben werden, überhaupt? Haben wir schon die richtigen Instrumente und Modelle zur Verfügung um existierende Probleme darzustellen – geschweige denn zukünftige? Kann man Wahlmanipulation tatsächlich mit einem Modell feststellen oder die Ausbreitung von Epidemien vorhersagen? Was haben Begriffe wie Big Data, Industrie 4.0 und das Internet of Things mit all dem zu tun? Und wie kann uns die junge Disziplin der Komplexitätswissenschaften bei diesen Fragen helfen?
Diskutieren Sie diese und viele andere Fragen mit unseren Expert_innen beim 23. TU Forum und finden Sie heraus, wie Daten, Modelle und Mathematik helfen können, unsere komplexe Realität besser zu verstehen.
Am Podium: Radu Grosu (TU Wien), Peter Klimek (Complexity Science Hub Vienna), Niki Popper (TU Wien) und Olga Saukh (Complexity Science Hub Vienna) Moderation: Norbert Fiala, Wissensvermittler & ehem. Fernsehredakteur
Diskutieren Sie mit – Eintritt frei, Anmeldung erforderlich.

CSH Workshop WeCoS - Understanding the Web as a Complex System: Complexity Science meets Web Science
Organized by Axel Polleres, David Garcia, and Vito DP Servedio.
The WeCoS workshop aims at bringing together researchers from the Semantic Web, Web Science, and Complexity Science in an interdisciplinary workshop about revisiting the question of understanding the web from different angles, deliberately looking outside of the core semantic web community for new and complementary approaches from empirical, theoretical, and social sciences to tackle the question of understanding the meaning of phenomena on the web as a complex system.
The workshop program can be found here.
CSH Talk by Luca Jacopo Uberti: "The Corruption U-Curve"
Join us for a talk by Luca Jacopo Uberti (Department of Political Science, University of Oslo) titled "The Corruption U-Curve" on Friday, October 27, at 2:00 pm at the Hub in Room 101.
Abstract: We replicate Saha and Gounder (Econ Model 31: 70-79, 2013), who show that the relationship between corruption and economic development exhibits an inverted U-shaped pattern. Pooled OLS estimates, however, should not be interpreted as conclusive evidence in support of a causal relationship. Using a much longer panel of 156 countries during 1900-2010, we show that a U shape shows up even after controlling for country-level heterogeneity, suggesting that the estimated relationship does not result from a version of the classic “Kuznets fallacy”. The curvilinear relationship is also robust to controlling for potential simultaneity using an instrumental variable approach. Still, the parabola implied by a fixed-effects model is considerably less “peaked” than the one implied by the corresponding OLS model.

CSH Workshop "Adaptive Networks and Catastrophies"
Organized by Stefan Thurner, Christian Kühn, and Leonhard Horstmeyer.
Adaptive co-evolving dynamic networks play a key role in ecological, epidemiological, social or financial systems. To understand the efficiency, resilience and systemic risks of such networks one needs a much deeper mathematical understanding of their critical behavior than is currently available. What remains largely unknown about these systems is their phase-structure, their critical transitions, if they can be classified into universality classes and whether it is possible to derive network-based early-warning signals. In particular in this workshop we want to discuss to what extent the network topology captures information about the critical transition and whether this allows us to explore the limits of predicting regime shifts and catastrophic events.
Complexity Science for Fundamental Urban Challenges
This workshop - organized in the framework of the Berlin Science Week by AIT Austrian Institute of Technology and CSH Vienna in the afternoon of Nov 7 - will introduce concepts of complexity & big data science with a special focus on challenges arising in the area of urbanization. There is evidence that the size of cities significantly affects factors such as health, communication, or opinion formation of people. Hence, how should cities be planned, built, and governed in an intelligent way? How can the immense data streams cities are producing be transformed into useful knowledge that can be used to develop a city in a sustainable, resilient, and resource-friendly way?
