CSH Workshop: “Monitoring Social Stress: a data-driven approach to understanding ‘polycrisis”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

The workshop is organized by Peter Turchin . It will take place on February 7–8, 2023 at the Complexity Science Hub Vienna.   Abstract:   "How resilient are societies to forces of disorder? Historical analysis reveals that the ability of societies to deal with a crisis, whether successfully or not, critically depends on its structural characteristics.…

CSH Talk by Nicolò Vallarano:”An Agent-based model of Ethereum Proof-of-Stake consensus”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

We present a minimalist agent-based model to efficiently simulate the Ethereum Proof-of-Stake (PoS) consensus protocol. The model depends on information diffusion: the main parameters are block and attestation latency as well as the underlying peer-to-peer topology. In addition to the model  description, we define measures to asses the quality of consensus, providing tools to observe…

CSH Talk by Gašper Tkačik: “Statistical analysis and optimality of biological systems”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

Normative theories and statistical inference provide complementary approaches for the study of biological systems. A normative theory postulates that organisms have adapted to efficiently solve essential tasks and proceeds to mathematically work out testable consequences of such optimality; parameters that maximize the hypothesized organismal function can be derived ab initio, without reference to experimental data.…

CSH Talk by José Moran: “Dynamics of (auto)correlated firms”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

The dynamics of firms can be understood by studying the properties of their growth rates. Although there has been a significant amount of work in trying to clarify the statistical properties of the growth-rate distribution, mimicking in many ways the tradition of studying the statistical properties of financial returns, a clear picture of their inter-temporal…

CSH Talk by Ambra Amico: “Structure and resilience of large-scale distribution networks: a complex system perspective to supply-chains”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

The focus of my talk is on distribution networks. In these networks, manufacturers and distributors work closely together to ensure consumers have access to goods and services. First, I will present a novel dataset, the ARCOS, which is still unexplored by the scientific community. This collects nearly half a billion records of opioid shipments in…

Workshop für Journalist:innen: “Put a Piece of Science in your Story”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

Ob Innenpolitikressort, Sport oder Kultur - eine Prise Wissenschaft würzt jeden Beitrag. Und das ohne großen Aufwand. In diesem Workshop wollen wir zeigen, wie. Die Wissenschaftsjournalistin Denise Hruby öffnet in diesem Workshop ihre Toolbox und zeigt, mit welchen Tipps und Tricks die Zusammenarbeit von Journalist:innen und Wissenschafter:innen erfolgreich verläuft. Die preisgekrönte Journalistin ist für internationale…
