Contagion in networks
Additive manufacturing plays a decisive role in the field of industrial manufacturing in a wide range of application areas today. However, process monitoring, …Miritello et al. (2011) use an approach that combines an explicit SIR disease model and a dynamic network to produce a static network that describes the spread of contagion in that network. Their method gives an estimate of the expected outbreak size, as well as the epidemic threshold on that network.The purpose of this study is to examine network learning through the application of contagion theories. The transmission of knowledge, sharing of resources, and facilitation of learning through contagion has interested both business-to-business and economic geography researchers. This study responds to calls in both research traditions for ...

This means that the structures and properties of these networks, and the information they propagate, play ...We develop a model for contagion risks and optimal security investment in a directed network of interconnected agents with heterogeneous degrees, loss functions, and security profiles. Our model generalizes several contagion models in the literature, particularly the independent cascade model and the linear threshold model. We state …This paper aims to construct a feasible two-layer network model for the emotional contagion of passenger groups in the case of large-scale flight delays. This improved emotional contagion model can study the emotional contagion mechanism and process of delayed passengers between online and offline social contact networks. …The risk contagion research is carried out from three aspects:guarantee mechanism, partner selection mechanism, and production parameter. The research shows that: (1) Firm size distribution takes on a power-law tail. (2) Guarantee network provides a channel for risk contagion and aggravates risk contagion among firms.Happiness and other emotions spread between people in direct contact, but it is unclear whether massive online social networks also contribute to this spread. Here, we elaborate a novel method for measuring the contagion of emotional expression. With data from millions of Facebook users, we show that rainfall directly influences the emotional content of …Monitoring and controlling financial contagion in banking systems is a challenging task, and micro-structural network contagion models are becoming …To assess the relevance of asymptotic formulae for studying contagion in networks with such sizes, we generate a scale-free network of 10,000 nodes with Pareto distributed exposures using the random graph model introduced by …Contagion is defined as a significant increase in cross-market co-movement of asset returns (Dungey et al., Citation 2004; Forbes & Rigobon, Citation 2002). According to Forbes and Rigobon (Citation 2002) and Celik (Citation 2012), the co-movements between financial markets may arise from the contagion or interdependence among financial markets ...The study of contagion dynamics in multilayer networks has become a hot topic. Networks have the characteristics of community structure. In this work, we present a comprehensive epidemic spreading model in multilayer networks with community structure. We consider the effects of population mobility, natural mortality and natural birth rate on ...Explosive contagion in SIS epidemics. The evolution of the spreading process depends both on transmission rates and dynamical rules imposed. For concreteness, we start the analysis by employing the exponential synergistic transmission rates (2) for contagion dynamics given by the rules of the SIS epidemic model applied to …In this paper, we study an interesting problem of emotion contagion in social networks. In particular, by employing an image social network (Flickr) as the basis of our study, we try to unveil how users' emotional statuses influence each other and how users' positions in the social network affect their influential strength on emotion. We ...Scientific Reports (2018) The threshold model has been widely adopted as a classic model for studying contagion processes on social networks. We consider asymmetric individual interactions in ...Bartering Networks - Bartering networks are more commConclusion. This work expands the literature on financ To avoid these limits, this paper analyzes contagion risk in endogenous financial networks, which includes interbank networks, inter-firm networks and bank-firm networks. Closest to our work is Delli Gatti et al. [12]. However, our paper is different from theirs in network formation. The network formation in this paper is endogenous, while that ...The European Union’s chief Ursula von der Leyen has told an American audience that the conflict contagion could spread to the Indo-Pacific..

However, contagion effects are usually difficult to identify, as they are often entangled with other factors, such as homophily in the selection ...Contagion in Financial Networks* Paul Glasserman and H.

A network monitoring tool monitors all of the computers on a network constantly checking for errors. It will check all of the compon...
We explore how the probability and potential impact of contagion is influenced by aggregate and idiosyncratic shocks, changes in network structure and asset market liquidity. Our findings suggest that financial systems exhibit a robust-yet-fragile tendency: while the probability of contagion may be low, the effects can be extremely widespread ...Feinstein Zachary & El-Masri Fatena, 2017.

The presence of complex contagion mechanisms has been assessed in various contexts 27, but largely in online social networks and forums 28,29, thanks to their unique data traceability.Definition 1. Given a network configuration σ, a liquidity shock of size θ at bank i, d ( j; σ, θ, i) is the least number of steps a shock can transmit via a directed path in the network from bank i to bank j, that is, the geodesic path from bank j to bank i through insolvent banks. By definition, d ( i; σ, θ, i ) ≡ 0.
Sentiment contagion such as the spread of panic in emergencies is By investigating the dynamics of systemic risk contagion across networks, we extend the DebtRank model to a three-layer network. The empirical results suggest that the multilayer structure of the banking system has a non-linear superimposed effect on systemic losses, with interbank lending and holdings common asset being the main … Risk Sharing and Contagion in Networks | The Review of Abstract.

Risk contagion to China’s banking network from 2 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 … The European Union’s chief Ursula von der LeyIn other words, the model of contagion in graphons As the COVID-19 outbreak has an impact on the global economy, Paul Glasserman & H.
