Contagion in networks
We present a model of worldwide crisis contagion based on the Google matrix analysis of the world trade network obtained from the UN Comtrade database. The fraction of bankrupted countries exhibits an on-off phase transition governed by a bankruptcy threshold κ related to the trade balance of the countries. For κ>κc, the contagion is …The inherent difficulty of distinguishing true causal contagion from confounding network homophily has been noted in detail elsewhere (see, for example, refs. 23,24). However, large observational ...

The complicated interaction patterns among heterogeneous individuals have a profound impact on the contagion process in the networks. In recent years, there has been increasing evidence for the emergence of many-body interactions between two or more nodes in a wide range of biological and social networks. To encode these …Complex networks represent the natural backbone to study epidemic processes in populations of interacting individuals. Such a modeling framework, …Using a case study of a newly emerging CSA, the role of social contagion in network evolution will be assessed. The merit of this research stems from its central task of …
In terms of Internet speed, most people agree that faster is always better. If you’re wondering what your network speed is, there are speed tests available on the Internet that enable you to test and measure the speed of your connection.Complex networks represent the natural backbone to study epidemic processes in populations of interacting individuals. Such a modeling framework, however, is naturally limited to pairwise interactions, making it less suitable to properly describe social contagion, where individuals acquire new norms or ideas after simultaneous exposure to multiple sources of infections.U.S. West Texas Intermediate crude futures for November delivery, which expired after settlement on Friday, fell 62 cents, or 0.7%, to $88.75 a barrel.(a) Forman-Ricci network entropy of random growing network of size \(N=10{,}000\) performed at \(10^3\) realizations.

First, moral contagion may be an antecedent process feeding into polarization or the increased distance among members of different political ideologies in online social networks (Barberá, Jost, Nagler, Tucker, & Bonneau, 2015; Brady et al., 2017) that people across the political spectrum have argued is a significant threat to civil discourse ...Abstract. Models of spreading processes in networks can help to provide insights into phenomena such as epidemic outbreaks, opinion formation, and failure propagation. Many contagion models are based on the idea that spreading occurs from an “infected” source to “non-infected” components, which may recover.Studying contagion risk in financial networks is very important for the stability of financial systems. But most models of financial networks often suffer from their very own problems. Many financial network models do not include interbank networks or inter-firm networks [8], [11], [13], [29], [33]. The study of Delli Gatti et al. [12] includes ... ….

However, appropriate models for studies of contagion in community networks remain elusive. Numerous studies indicate the effects of geodetic properties such as the degrees of separation, distributions, mixing and cover times, diameters of networks or degrees of separation, and centrality and clustering of social interactions, and these have ...Core-periphery networks are highly susceptible to contagion and generate fire sales of assets that exacerbate financial contagion beyond the mechanical role of network structure. In contrast, contagion is minimal on circle networks and market prices remain stable. Uncertainty on the location of the shock has little influence.Antonio Cabrales & Piero Gottardi & Fernando Vega-Redondo, 2017.
