COVID-19 has brought a great impact on people's lives around the world. This paper aims to study the influencing factors of people's fear of missing out (FOMO) toward personal ICT use and its further impact on life satisfaction during the pandemic. A sample consisting of 318 participants was obtained by an online survey in China. Partial least squares structural equation modeling (PLS-SEM) was used for data analysis. The results suggested that people's anxiety and boredom brought by the pandemic are positively correlated with their FOMO. People with higher FOMO used personal ICTs more frequently for both social and process purposes. Furthermore, the social use of ICTs promoted people's life satisfaction, while the process use of ICTs had no significant effect on life satisfaction. Several theoretical and practical implications were discussed based on the results.

Online reviews, as one kind of new marketing methods, are becoming increasingly important in influencing preferences and decision-making of consumers. In view of this, this paper conducts an empirical study on Dangdang Books, constructs a research framework on correlation between product sales and aspects of online reviews, and explores the correction through the panel data econometric model. Compared to former research, our work analyzes real data on product sales instead of the rank of sales. Based on our study results and comparison with others' research results on Amazon (amazon.com), we provide several guiding suggestions for online review systems in the Chinese context. These systems should pay attention to emotional tendency of reviews, reviewer ranking mechanisms, spotlight reviews, review format and review voting mechanisms.
