Effect of Social Media on Opinion Formation.

- Mathematics
- 2018

In this work, we investigate the effect of social media on the process of opinion formation in a human population. This effect is modeled as an external field in the dynamics of the two-dimensional…

The External Field-Like Effect to the Evolution of Public Opinion in the Stauffer-Galam Model

- Physics
- 2020

In this work, we performed numerical simulation to investigate the effect of an “external field” to the evolution of public opinion in the Stauffer-Galam or two-dimensional Sznajd opinion model.…

The influence of periodic external fields in multi-agent models with language dynamics

- EconomicsPhysical review. E
- 2017

It is shown that a single external field, broadcasting information at regular time intervals, can reverse the majority opinion of the population, provided the frequency and the effectiveness of the sent messages lie above well-defined thresholds.

Opinion evolution in the presence of constant propaganda: homogeneous and localized cases

- Mathematics
- 2021

Abstract The opinion evolution of a group of agents arranged in a square lattice in the presence of external constant propaganda is studied. The contagion between agents is modeled according to the…

Imperfect bifurcations in opinion dynamics under external fields

- PhysicsJournal of Statistical Mechanics: Theory and Experiment
- 2020

This model investigates, through a kinetic-exchange model, the impact that an external field, like advertising and propaganda, has on opinion dynamics, and shows how the external bias gives rise to imperfect bifurcations, and cusp catastrophes.

Agent-Based Spatial Dynamic Modeling of Opinion Propagation Exploring Delaying Conditions to Achieve Homogeneity

- BusinessSOCO-CISIS-ICEUTE
- 2016

The effect of spatial interaction of the agents, which are free to move in a given space, following attraction dynamics towards agents with similar opinions, is explored.

Agent-Based Spatial Dynamics Explaining Sustained Opinion Survival

- BusinessIWINAC
- 2017

A model is proposed that shows opinion survival properties, and the effect of spatial perception parameters in the opinion difussion and survival process is explored, and spatial relations are modulating friendship and influence relations.

DAMAGE SPREADING, COARSENING DYNAMICS AND DISTRIBUTION OF POLITICAL VOTES IN SZNAJD MODEL ON SQUARE LATTICE

- Physics
- 2001

In the Sznajd model of sociophysics on the square lattice, neighbors having the same opinion convince their neighbors of this opinion. We study scaling of the cluster growth. The spreading-of-damage…

Nonequilibrium transition induced by mass media in a model for social influence.

- PhysicsPhysical review. E, Statistical, nonlinear, and soft matter physics
- 2005

This work studies the effect of mass media, modeled as an applied external field, on a social system based on Axelrod's model for the dissemination of culture, which undergoes a nonequilibrium phase transition between an ordered phase specified by the mass media and a disordered one.

Effects of agents' mobility on opinion spreading in Sznajd model

- Economics
- 2008

Abstract
Under synchronous updating and allowing the agents to move
in the lattice or underlying network, we find that the Sznajd model always
reaches a consensus as a steady state, – because agent…

Effects Of Mass Media And Cultural Drift In A Model For Social Influence

- Physics
- 2006

In the context of an extension of Axelrod's model for social influence, we study the interplay and competition between the cultural drift, represented as random perturbations, and mass media,…

OPINION FORMATION ON A DETERMINISTIC PSEUDO-FRACTAL NETWORK

- Physics
- 2004

A model for elections based on the Sznajd model is studied and the exponent obtained for the distribution of votes during the transient agrees with those obtained for real elections in Brazil and India.

Effects of mass media action on the Axelrod model with social influence.

- EconomicsPhysical review. E, Statistical, nonlinear, and soft matter physics
- 2010

The Axelrod model with social influence interaction is extended through the inclusion of a superagent which acts over the whole system and has non-null overlap with each agent of the society and might be relevant in several socioeconomic contexts and for the study of the emergence of collective behavior in complex social systems.

SZNAJD SOCIAL MODEL ON SQUARE LATTICE WITH CORRELATED PERCOLATION

- Physics
- 2001

The Sznajd model for the spread of opinions is applied to the incipient infinite percolation cluster on the square lattice, with and without power-law correlations for the occupied sites. We trace…

Statistical physics of social dynamics

- Physics, Education
- 2009

Statistical physics has proven to be a fruitful framework to describe phenomena outside the realm of traditional physics. Recent years have witnessed an attempt by physicists to study collective…
