We develop a theoretical framework for the study of epidemiclike social contagion in large scale social systems. We consider the most general setting in which different communication platforms or categories form multiplex networks. Specifically, we propose a contact-based information spreading model, and show that the critical point of the multiplex system associated with the active phase is determined by the layer whose contact probability matrix has the largest eigenvalue. The framework is…

Social contagions on multiplex networks with heterogeneous population

Spreading of memes on multiplex networks

A model for the spreading of online information or ‘memes’ on multiplex networks is introduced and analyzed using branching-process methods, which demonstrates that the dynamical system is poised near a critical point, which is known to lead to heavy-tailed distributions of meme popularity similar to those observed in empirical data.

MM-SIS: Model for multiple information spreading in multiplex network

Epidemic spreading on time-varying multiplex networks

It is found that higher values of multiplexity significantly reduce the epidemic threshold especially when the temporal activation patterns of nodes present on multiple layers are positively correlated, and when the average connectivity across layers is very different, the contagion dynamics is driven by the features of the more densely connected layer.

Social contagions with communication channels alternation on multiplex networks

A non-Markovian behavior spreading model in multiplex networks that takes into account the CCA mechanism is proposed, and a generalized edge-based compartmental method is developed to describe the spreading dynamics.

Interplay Between Spreading and Random Walk Processes in Multiplex Networks

A susceptible-infected-susceptible-based model is developed on the top of these networks, which is integrated with the transition of agents across layers, and a critical infection rate for which an epidemic dies out in a multiplex network is obtained.

Co-diffusion of social contagions

A new threshold model for the diffusion of multiple contagions is proposed and it is shown that within a band of synergy, contagions on the lattices undergo bimodal or trimodal branching if they are the slower diffusing contagion, especially those that diffuse on lattices.

A general social contagion dynamic in interconnected lattices

Social multiplexity in a generalized Axelrod model of cultural dissemination

It is found that the effect of multiplexity differs between treatments, but in most cases promotes cultural convergence, and an important mechanism is that local differences in connectivity between the layers lead indirectly to more cultural convergence while increasing the time to reach the end-state.

Percolation in multiplex networks with overlap.

It is shown that the overlap among layers can improve the robustness of interdependent multiplex systems and change the critical behavior of the percolation phase transition in a complex way.

The results extend the existing work on complex contagions in several directions by providing solutions for coupled random networks whose vertices are neither identical nor disjoint, and showing that content-dependent propagation over a multiplex network leads to a subtle relation between the giant vulnerable component of the graph and the global cascade condition that is not seen in the existing models in the literature.

Multi-Stage Complex Contagions

It is demonstrated that the presence of even one additional stage introduces novel dynamical behavior, including interplay between multiple cascades, which cannot occur in single-stage contagion models.

On the dynamical interplay between awareness and epidemic spreading in multiplex networks

The analysis of the interrelation between two processes accounting for the spreading of an epidemic, and the information awareness to prevent its infection, on top of multiplex networks reveals the phase diagram of the incidence of the epidemics and allows the evolution of the epidemic threshold depending on the topological structure of the multiplex and the inter correlation with the awareness process.

Correlated multiplexity and connectivity of multiplex random networks

It is demonstrated that the correlated multiplexity can drastically affect the properties of a giant component in the network when the degrees of a node for different interactions in a duplex Erdős–Rényi network are maximally correlated.

Branching Dynamics of Viral Information Spreading

A detailed analysis of a study of real viral marketing campaigns where tracking the propagation of a controlled message allowed us to analyze the structure and dynamics of a diffusion graph involving over 31,000 individuals found that information spreading displays a non-Markovian branching dynamics that can be modeled by a two-step Bellman-Harris branching process.

Infectious Disease Modeling of Social Contagion in Networks

It is found that since the 1970s, the rate of recovery from obesity has remained relatively constant, while the rates of both spontaneous infection and transmission have steadily increased over time, suggesting that the obesity epidemic may be driven by increasing rates of becoming obese, both spontaneously and transmissively, rather than by decreasing rates of losing weight.

Discrete-time Markov chain approach to contact-based disease spreading in complex networks

Many epidemic processes in networks spread by stochastic contacts among their connected vertices. There are two limiting cases widely analyzed in the physics literature, the so-called contact process

Community Structure in Time-Dependent, Multiscale, and Multiplex Networks

A generalized framework of network quality functions was developed that allowed us to study the community structure of arbitrary multislice networks, which are combinations of individual networks coupled through links that connect each node in one network slice to itself in other slices.

Multirelational organization of large-scale social networks in an online world

This work presents the first empirical large-scale verification of the long-standing structural balance theory, by focusing on the specific multiplex network of friendship and enmity relations, and explores how the interdependence of different network types determines the organization of the social system.

It is shown that heterogeneity plays an ambiguous role in determining a system's stability: increasingly heterogeneous thresholds make the system more vulnerable to global cascades; but anincreasingly heterogeneous degree distribution makes it less vulnerable.
