The tremendous market growth of mobile platforms for esports underscores the need to understand players' psychological states and consumption behavior. Based on flow theory, this study examines players' psychological states (flow and clutch experiences) and consumption behavior based on the interaction effects of playing frequency, playing duration and players' levels on the PC (LOL – League of Legends) and mobile (LOLWR – League of Legends: Wild Rift) versions of the same esports title.

Data were collected from 930 valid responses and analyzed with confirmatory factor analysis and multiple regression (PROCESS macro, Model 3).

There are two main findings. First, across PC and mobile participants, casual gamers (low playing frequency and duration) have firm purchase intention when they have a clutch experience, but flow experience hinders their purchasing intention. Second, hardcore gamers' (high playing frequency and duration) psychological states are clearly distinguished according to technological platforms. Flow experience is the most effective for their purchase intention in the PC platform, but both flow and clutch states are important in the mobile platform. Flow experience is essential overall for hardcore gamers to intend their in-game item purchasing.

This study has two primary originality/values. First, this study explores flow and clutch together to measure psychological states and the impact on the purchase intention of in-game items. Second, the interacting effects of playing frequency, duration, and skill level with technical platforms (i.e. PC and mobile) for esports gaming.

Customers’ innovativeness regarding services and products affects their purchase behavior. The purpose of this paper is to examine the moderation effect of fitness innovativeness (FI) (domain-specific innovativeness) and duration of stay on fitness customers’ revisit frequency.

This is a quantitative study. The purposive sampling survey method was used to obtain samples from the Taipei Nangang Fitness Center. Data were analyzed by moderated regression analysis.

The empirical results from 192 valid questionnaires that were obtained for data analysis revealed that FI has a positive impact on revisit frequency, and this impact is further increased if an individual is inclined to exercise and to stay longer at the fitness center.

A matrix of fitness innovator segments was developed to illustrate the research and managerial implications.

The purpose of this paper is to understand how team identification and country influence professional baseball team spectators’ evaluations of service quality factors, perceived value and future behavioral intentions.

Data were collected online from sports consumers of the Chinese Professional Baseball League (CPBL) in Taiwan (n = 600) and Major League Baseball in the USA (n = 460). A regression-based estimation method (PROCESS) and structural equation modeling approach were used to assess the relationships.

Both direct and indirect (via perceived value) effects of most service quality factors (schedule convenience, economic consideration, game amenities, ticket service and venue quality) on behavioral intentions are stronger for lowly than for highly identified CPBL fans. The indirect effect of home team on behavioral intentions is stronger for the lowly identified CPBL fans. The direct effect of game amenities and the indirect effect of venue quality (via perceived value) on behavioral intentions are stronger for the highly identified MLB fans. The indirect effect of opposing team and economic consideration is stronger for the lowly identified MLB fans. The positive relationship between venue quality and perceived value is stronger for the USA than for Taiwan fans. The relationships between game amenities and perceived value and between perceived value and behavioral intention are perceived to be invariant between fans from the two countries. Taiwan fans’ behavioral intentions tend to be directly and indirectly affected by service quality factors, whereas US fans’ behavioral intentions tend to be indirectly affected by service quality factors.

The study provides empirical evidence of the moderating role of team identification associated with the relationships between separate service quality factors, perceived value and behavioral intentions among consumers of a professional spectator sports in two different countries.

This paper aims to develop resonant vibratory gyroscopes for high sensitive detection. The dynamic characteristics of resonant vibratory gyroscopes are investigated.

Firstly, the working principle and the dynamic output characteristics of the resonant vibratory gyroscope could be described by the damped Mathieu equation. Moreover, an approximate analytical method based on the small parameter perturbation has been used for the purpose of investigating the approximate solution of the damped Mathieu equation. Finally, to verify the feasibility of the approximate analytical method of the damped Mathieu equation, dynamic output characteristics’ experiments of the resonant vibratory gyroscope are built.

The theoretical analysis and numerical simulations show that the approximate solution of the damped Mathieu equation is close to the dynamic output characteristics of the resonant vibratory gyroscope. On the other hand, it is concluded from the tested result that there exists a correlation between the theoretical curve and the experimental data processing result, meaning the damped dynamics analytical method is effective in building resonant vibratory gyroscopes.

This paper seeks to establish a foundation for optimizing and testing the performance of the resonant vibratory gyroscope. To this end, the approximate analytical method of the damped Mathieu equation was discussed. The result of this research has proved that the dynamic characteristics based on the damped Mathieu equation is an effective approach and is instructional in the practical resonant sensor design.
