Struggling with change: The fragile resilience of collectives
Frank Schweitzer, Christian Zingg, Giona Casiraghi
Collectives form non-equilibrium social structures characterised by a volatile dynamics. Individuals join or leave. Social relations change quickly. Therefore, differently from eng…
The downside of heterogeneity: How established relations counteract systemic adaptivity in tasks assignments
Giona Casiraghi, Christian Zingg, Frank Schweitzer
We study the lock-in effect in a network of task assignments. Agents have a heterogeneous fitness for solving tasks and can redistribute unfinished tasks to other agents. They lear…
Fragile, yet resilient: Adaptive decline in a collaboration network of firms
Frank Schweitzer, Giona Casiraghi, Mario V. Tomasello +1
The dynamics of collaboration networks of firms follow a life-cycle of growth and decline. That does not imply they also become less resilient. Instead, declining collaboration net…
Intervention scenarios to enhance knowledge transfer in a network of firm
Frank Schweitzer, Yan Zhang, Giona Casiraghi
We investigate a multi-agent model of firms in an R\&D network. Each firm is characterized by its knowledge stock , which follows a non-linear dynamics. It can grow with…
Probing the robustness of nested multi-layer networks
Giona Casiraghi, Antonios Garas, Frank Schweitzer
We consider a multi-layer network with two layers, , . Their intra-layer topology shows a scale-free degree distribution and a core-periphery stru…
Improving the robustness of online social networks: A simulation approach of network interventions
Giona Casiraghi, Frank Schweitzer
Online social networks (OSN) are prime examples of socio-technical systems in which individuals interact via a technical platform. OSN are very volatile because users enter and exi…
What is the Entropy of a Social Organization?
Christian Zingg, Giona Casiraghi, Giacomo Vaccario +1
We quantify a social organization's potentiality, that is its ability to attain different configurations. The organization is represented as a network in which nodes correspond to…
Analytical Formulation of the Block-Constrained Configuration Model
Giona Casiraghi
We provide a novel family of generative block-models for random graphs that naturally incorporates degree distributions: the block-constrained configuration model. Block-constraine…
Multiplex Network Regression: How do relations drive interactions?
Giona Casiraghi
We introduce a statistical regression model to investigate the impact of dyadic relations on complex networks generated from observed repeated interactions. It is based on generali…
Generalized Hypergeometric Ensembles: Statistical Hypothesis Testing in Complex Networks
Giona Casiraghi, Vahan Nanumyan, Ingo Scholtes +1
Statistical ensembles of networks, i.e., probability spaces of all networks that are consistent with given aggregate statistics, have become instrumental in the analysis of complex…
