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 ...

Stability Analysis of a Rumor-Spreading Model with Two Time Delays and Saturation Effect

Mathematics
Time delay and nonlinear incidence functions have a significant effect on rumor-spreading. In this article, a rumor-spreading model with two unequal time delays and a saturation effect is proposed.

Rumor Spreading Model Considering Individual Activity and Refutation Mechanism Simultaneously

IEEE Access, 2020
With the rapid development of social networks, an increasing number of factors will affect the spread of rumors. In this paper, we simultaneously consider individual activity differences and rumor-refuting nodes, and we propose a new multifactor model ...

Dynamical behavior of a stochastic SICR rumor model incorporating media coverage

Frontiers in Physics, 2022
Rumor propagation in the new media era poses a huge threat to maintaining the normal order of social life. In this context, we put forth a nonlinear dynamics-based stochastic SICR rumor model that integrates media coverage with science education.

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(

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.

Low Randomness Rumor Spreading via Hashing [PDF]

, 2012
International audienceWe consider the classical rumor spreading problem, where a piece of information must be disseminated from a single node to all n nodes of a given network. We devise two simple push-based protocols, in which nodes choose the neighbor

From disorientation to preparedness: Information practices as scaffolding in acute crises

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This qualitative study examines how adults in Israel enacted information practices during an acute national crisis. Using the information transitions framework, we investigate how concrete practices emerge and evolve across three stages: understanding, negotiating, and resolving. Semi‐structured Zoom interviews with 18 adults were analyzed via

Rumor propagation meets skepticism: a parallel with zombies

, 2018
We propose a model of rumor spreading in which susceptible, but skeptically oriented individuals may oppose the rumor. Resistance may be implemented either by skeptical activists trying to convince spreaders to stop their activity, becoming stiflers or ...

Limits for Rumor Spreading in stochastic populations

CoRR, 2017
Biological systems can share and collectively process information to yield emergent effects, despite inherent noise in communication. While man-made systems often employ intricate structural solutions to overcome noise, the structure of many biological systems is more amorphous.
