Mathematical Model of the Dynamics of Rumor Propagation

Journal of Applied Mathematics and Physics, 2019
In this study, we proposed a deterministic mathematical model that attempts to explain the propagation of a rumor using epidemiological models approach. The population is divided into four classes which consist of ignorant individuals, I(t), spreaders targeting community through media, M(t), spreaders targeting community through verbal communication, G(

Rumor Propagation Model: An Equilibrium Study

Mathematical Problems in Engineering, 2010
Compartmental epidemiological models have been developed since the 1920s and successfully applied to study the propagation of infectious diseases. Besides, due to their structure, in the 1960s an interesting version of these models was developed to clarify some aspects of rumor propagation, considering that spreading an infectious disease or ...

Optimal control of a rumor propagation model with different propagation degrees in social network / Tang Yingfeng [PDF]

, 2020
Rumor is a social interaction of information, and its development is of great significance to human beings. In this paper, by studying the D K model and a rumor model spreading with rumor latent period, deduces the rumor model with differe nt ...

Spatio-temporal pattern formation mechanism of an epidemic-like information propagation model with diffusion behavior

Ain Shams Engineering Journal
In order to effectively warn against and control the spread of online rumors, it is essential to research the dynamic process of rumor propagation. This paper presents a reaction-diffusion rumor propagation model with a time delay.

A Dynamic Competition and Predation Model for Rumor and Rumor-Refutation

IEEE Access, 2021
Controlling rumors is related to the interplay between the rumor and rumor refutation, which compete to attract the unaware. And rumor refutation preys on the rumors, and try to eliminate rumors.

Symbols of Climate Action: Audit Labor and the Production of Carbon Credits

Economic Anthropology, EarlyView.
ABSTRACT Voluntary carbon markets (VCMs) are promoted as tools for financing climate mitigation, yet their effectiveness and credibility remain contested. This article examines how carbon credits are produced and destabilized as symbols of climate action, emphasizing the forms of ecological and audit labor that sustain their legitimacy.
