CSH Talk by Hossein Kermani: Bots vs. humans: discursive activism during the pandemic in the Iranian Twittersphere

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

This paper investigates how automated accounts and human users framed the pandemic in Iran. While there is a growing body of literature on bot activism, our knowledge of how bots intervene in humans' organic discursive practices in authoritarian regimes, particularly during the pandemic, is niche. We based this study on networked framing theory and used…

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”

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…

CSH Talk by Karolina Safarzynska: “Material leakage in the circular economy: an input-output agent-based model”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

Abstract: We propose an agent-based input-output model of the EU. We make input-output analysis dynamic by linking it to an agent-based model of the capital sector, in which heterogeneous capital firms engage in innovation to improve capital productivity. I will discuss how our method affects the predictions of future resource extraction compared to a static…

CSH Talk Maria Henkel: “Named Entity Recognition for Scientometric Analysis”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

Abstract: A recent study by Castro Torres and Alburez-Gutierrez (2022) shows that social sciences studies using data from the global North (Europe and North America) are less likely to contextualize their title than studies from the global South. The authors conclude that this omission of geo-contextualization from the global North could potentially constitute an unwarranted…

CSH Talk by Robert Axtell: “Empirical Structure of U.S. Business Firms”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

Title: "Empirical Structure of U.S. Business Firms"   Abstract: Nearly 4 dozen empirical patterns and gross regularities have been discovered in recent years in firm-level micro-data (derived from tax filings, primarily) for the 5-6 million American businesses that employ workers each year. These include power law distributions of firm sizes, labor productivities, importer and exporter…

CSH Talk by Niraj Kushwaha: “Population waves in sessile organisms”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

About The mathematical laws of life manifest scaling regularities such as the relationship between mass and metabolism for the smallest to the largest organisms on Earth. These laws lack essential components representing interaction between organisms while sharing limited resources. Once accounted for, these components can bring significant variation to the predicted demographic laws using just…

CSH Talk by Corinna Coupette: “Exploring Evolving Hypergraphs: Methods and Applications”

Complexity Science Hub Vienna Josefstädter Straße 39, Vienna

Many complex systems feature multilateral interactions that change over time. These systems are faithfully represented as evolving hypergraphs: Graphs in which nodes or edges can be added, modified, or deleted, and any number of nodes can participate in an edge. In this talk, I will present ongoing work on methods to explore evolving hypergraphs, illustrated…
