Distinguishing influence-based contagion from homophily-driven diffusion in dynamic networks. Proceedings of the National Academy of Sciences , 106 (51) , 21544 – 21549 . CrossRef Google Scholar PubMedThe financial crisis of 2007–2008 produced an enormous impact on financial, social and political levels for many world countries (see e.g. [1, 2]).After this crisis the importance of contagion in financial networks gained a practical importance and generated serious academic research with various models proposed for the description of this …This study examines the interface of three elements during co-contagion diffusion: the synergy between contagions, the dormancy rate of each individual contagion, and the multiplex network topology. Dormancy is defined as a weaker form of “immunity,” where dormant nodes no longer actively participate in diffusion, but are still susceptible to …

Accessing your cable network’s channel guide can help you plan which shows you want to watch, and how. Plus, if your cable subscription offers DVR functions, you can plan to record your favorite shows so you don’t miss a beat.The proposed contagion-based dynamics are verified through an empirical multi-city analysis, and can be used to monitor, predict and control the fraction of congested links in the network over ...Abstract. People increasingly turn to online social networks for information and debate. This means that the structures and properties of these networks, and the information they propagate, play ...We measure the emotional valence of content the users are exposed to before posting their own tweets. We determine that on average a negative post follows an over-exposure to 4.34% more negative ...

Using these algorithms, we study the spread of contagion in scale-free networks with 1,000 players using millions of Monte Carlo simulations. Our analysis provides quantitative and qualitative insight into the design of policies to control or spread contagion in networks. The scope of application is enlarged given the many other situations ...We estimated these contagion effects by combining daily global weather data, which creates exogenous variation in running among friends, with data on the network ties and daily exercise patterns ...Section 3 describes our network model of contagion. Section 4 presents and discusses the computer experiments and simulation results. Finally, Section 5 concludes the paper. 2. Related literature. Our study is related to separate strands of the literature on interbank networks. First, it relates to the literature on contagion channels. ….

On the one hand, it drives banks to form a network that minimizes contagion. On the other hand, it concentrates the risk of fire sale at the core of big banks. Interestingly, network thus formed under imperfect information may partially resolve network uncertainty. This is because equilibrium in our model is a self-fulfilling phenomenon.Table 1. Four different models and corresponding algorithms describe influence or information spreading in social networks. Alg-cc and Sim-sc, indicated by the green colour, are basic models for describing complex contagion and simple contagion processes, respectively. Alg-cc is based on an analytical mathematical expression.1. Introduction. Social networks are central to the understanding of human behaviors (Barsade, 2002, Hill et al., 2010a).Recent studies of social networks have been performed in various fields, including social psychology, computer science, and physics, and multi-disciplinary studies of social networks have demonstrated key influences that …

Contagions and homophilous diffusion are both typified by correlations between network structure and individual outcomes over time ( 1 – 3, 5 – 11, 17, 21, 22 ). Two empirical patterns have been used to substantiate claims of peer influence and contagion in networks ( i) assortative mixing —correlations of behaviors among linked …tion is how network structure interacts with other potential sources of contagion. In the run-up to the crisis, leverage levels increased and capital buffers at some banks were extremely thin. Large financial institutions had increased their reliance on short-term Contagion in Financial Networks † Paul Glasserman and H. Peyton Young*Contagion in Financial Networks* Paul Glasserman and H. Peyton Young . October 20, 2015 . Among the many factors contributing to the financial crisis the increasing of 2007-2009, interconnectedness of the global financial …

jordan helms For each type of financial network, the left figure (a, c, e, g) shows the contagion without overlapping portfolios, and the right figure (b, d, f, h) shows the contagion with overlapping portfolios. ku women bbblue box locator This contribution focuses on the methodology applied in papers that investigate the dynamics of contagion in financial networks using numerical simulations. In these papers, a propagation of losses and defaults in a financial system is modeled as a direct balance-sheet contagion (a.k.a. counterparty contagion), that is the direct …First, we derive a contagion ripple-spreading network model (CRNM) from the pioneering work of Hu et al. (2011) to reveal the ripple-spreading paths of financial contagion. In the CRNM, we integrate information on the amplifying effect and risk prevention capability of financial markets, market distances, and contagion spreading … hawkhatesyou onlyfans nudes 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 ...Jan 28, 2016 · Explosive Contagion in Networks | Scientific Reports. The spread of social phenomena such as behaviors, ideas or products is an ubiquitous but remarkably complex phenomenon. A successful avenue... japanese essayimagenow perceptive contentmadeline island pet friendly lodging Many behavioral phenomena have been found to spread interpersonally through social networks, in a manner similar to infectious diseases. An important difference between social contagion and traditional infectious diseases, however, is that behavioral phenomena can be acquired by non-social mechanisms as well as through social transmission. was jalen wilson drafted In financial networks links stand for loan agreements between financial institutions which are represented by the nodes of the network. There are two types of contagion that have been studied on networks formed by financial links. The first type …According to social contagion theory [29, 30], a person's attitudes and behavior can be contagious to others in their social networks [31]. Thus, people tend to adapt their actions to the behavior ... kansas vs tennessee tech3901 rainbow blvd kansas city ksku vs kstate basketball game Contagion in Financial Networks 3 sheets. The interactions between –nancial intermediaries following shocks make for non-linear system dynamics, and our model provides a framework for isolating the probability and spread of contagion when claims and obligations are interlinked.
