IVESR Rumor Spreading Model in Homogeneous Network with Hesitating and Forgetting Mechanisms

, 2021
In this paper, we study a new IVESR rumor spreading model with hesitating and forgetting mechanisms in homogeneous network. The rumor free and rumor prevailing equilibriums, and the basic reproduction number R0 are calculated from the mean-field ...

Adaptive Rumor Spreading

, 2015
Motivated by the recent emergence of the so-called opportunistic communication networks, we consider the issue of adaptivity in the most basic continuous time asynchronous rumor spreading process. In our setting a rumor has to be spread to a population; the service provider can push it at any time to any node in the network and has unit cost for doing ...

Dynamic analysis and optimum control of a rumor spreading model with multivariate gatekeepers

AIMS Mathematics
Rumor spreading on social media platforms can significantly impact public opinion and decision-making. In this paper, we proposed an innovative ignorant-spreader-expositor-hibernator-remover (ISEHR) rumor-spreading model with multivariate gatekeepers ...

Emergence of influential spreaders in modified rumor models

, 2012
The burst in the use of online social networks over the last decade has provided evidence that current rumor spreading models miss some fundamental ingredients in order to reproduce how information is disseminated.

Tripartite Evolutionary Game Analysis for Rumor Spreading on Weibo Based on MA-PT

IEEE Access, 2021
With the rapid development of social media, Weibo rumors have increasingly attracted widespread attention. To maintain sustainable development of network ecology, it is necessary to clarify the evolution law of rumor propagation. First, evolutionary game

Randomized Rumor Spreading in Dynamic Graphs [PDF]

, 2014
We consider the well-studied rumor spreading model in which nodes contact a random neighbor in each round in order to push or pull the rumor. Unlike most previous works which focus on static topologies, we look at a dynamic graph model where an adversary is allowed to rewire the connections between vertices before each round, giving rise to a sequence ...

Gossip vs. Markov Chains, and Randomness-Efficient Rumor Spreading [PDF]

, 2013
We study gossip algorithms for the rumor spreading problem which asks one node to deliver a rumor to all nodes in an unknown network. We present the first protocol for any expander graph $G$ with $n$ nodes such that, the protocol informs every node in $O(

The String of Diamonds Is Tight for Rumor Spreading [PDF]

, 2017
For a rumor spreading protocol, the spread time is defined as the first time that everyone learns the rumor. We compare the synchronous push&pull rumor spreading protocol with its asynchronous variant, and show that for any n-vertex graph and any ...

Assessing the Impact of Promotions on Consumer Purchasing Behavior During Crises

Agribusiness, EarlyView.
ABSTRACT Understanding how households modify their food expenditure decisions during times of crisis is essential because consumer purchasing behavior frequently changes during these times. This study looks at these behavioral shifts during the COVID‐19 pandemic, concentrating on how price sensitivity and response to sales promotions changed over the ...
