A Multi-Information Spreading Model for One-Time Retweet Information in Complex Networks

In the realm of online social networks, the spreading of information is influenced by a complex interplay of factors. To explore the dynamics of one-time retweet information spreading, we propose a Susceptible-Infected-Completed (SIC) multi-information spreading model. This model captures how multiple pieces of information interact in online social networks by introducing inhibiting and enhancement factors. The SIC model considers the completed state, where nodes cease to spread a particular piece of information after transmitting it. It also takes into account the impact of past and present information received from neighboring nodes, dynamically calculating the probability of nodes spreading each piece of information at any given moment. To analyze the dynamics of multiple information pieces in various scenarios, such as mutual enhancement, partial competition, complete competition, and coexistence of competition and enhancement, we conduct experiments on BA scale-free networks and the Twitter network. Our findings reveal that competing information decreases the likelihood of its spread while cooperating information amplifies the spreading of mutually beneficial content. Furthermore, the strength of the enhancement factor between different information pieces determines their spread when competition and cooperation coexist. These insights offer a fresh perspective for understanding the patterns of information propagation in multiple contexts.

Is Conspicuous Consumption Influenced by Cyber-Ostracism? A Moderated Mediation Model

This study starts from the cyber-ostracism experience that often occurs during social media use. Based on compensatory control theory, we explore the mechanism by which cyber-ostracism affects consumers' conspicuous consumption through the sense of control and also explore the moderating role of social media use intensity and implicit personality. This study used a sample of 407 social media users in China to verify the relationship between variables. The findings show that: there is a significant positive effect of cyber-ostracism on conspicuous consumption; sense of control plays a mediating role in the relationship between cyber-ostracism and conspicuous consumption; social media use intensity negatively moderates the relationship between cyber-ostracism and sense of control, and implicit personality moderates the relationship between sense of control and conspicuous consumption. The findings of the study help to reveal the formation mechanism of social media users' conspicuous consumption, which has important theoretical significance and practical value for establishing correct consumption concepts in the social media context.
