  • Present study investigates the impact of privacy concerns of SNS users on continued intention to use since the privacy infringement issue emerges when smartphone use has been increasingly prevalent. In particular, moderating effect of perceived usefulness and mediating effect of trust between privacy concerns and continued intention to use are further evaluated. Contrary to the expectation that users of SNS will resist to use SNS because of privacy concerns, the number of users of SNS is still growing exponentially. Current paradox might be explained by the intervening factors such as perceived usefulness and trust. The results verify the mediating role of trust and no moderating role of perceived usefulness. Finally, the practical implication for businesses who utilize SNS in their marketing strategy is discussed.

  • This study will be an exploratory study from the perspective of IWOM on the intention of word-of-mouth transmission. And based on 256 questionnaire survey data of E-Commerce live broadcast consumers, structural equation modeling is used to explore the paths and mechanisms of influence of consumers' perceived IWOM and perceived value on oral transmission intention in China's E-Commerce live broadcast. The results found that consumers' perceived IWOM had a positive effect on perceived usefulness and perceived entertainment, and that perceived usefulness had a positive effect on purchase intention while perceived entertainment had no direct effect on word-of-mouth transmission intention. Perceived IWOM also indirectly influences willingness to pass on word-of-mouth by affecting perceived value. Among them, the mediating effect of perceived usefulness in the path of perceived network influence on word-of-mouth transmission intention is greater than that of perceived entertainment.

  • Emoticons perform an important role as an enhancement to written communication, in areas such as Windows Live Messenger instant messaging, e-mails, mobile Short Message Services (SMS), and others. Emoticons are graphic images used in communications to indicate the feelings of people exchanging messages via mobile technology. In this research, the perceived usefulness of the emoticon in mobile phone text messages is verified with consumers using the five construct model of Huang. A K-means clustering technique for separating three groups based on levels of perceived usefulness of mobile emoticons is used with a structural equation model test using Smart PLS 2.0, and the bootstrap re-sampling procedure. We analyzed relationships among use of emoticons, enjoyment, interaction, information richness, and perceived usefulness. The results show there are relationships among use of emoticons, enjoyment, interaction, perceived usefulness, and information richness, however enjoyment of emoticons did not significantly affect the perceived usefulness of messages with emoticons alone. The results suggest emoticons have different affects on emotion in both mobile, and Messenger contexts. Our study did not consider more detailed media properties, and thus more studies are needed. Our research results contribute to mobile communication activation, provides companies with an understanding of key characteristics of consumers who use emoticons, and provides useful implications for improving management and marketing strategies.

  • The present study aims to investigate the perceived usefulness of business coaching as a moderator between the association of entrepreneurial competencies and business success of women micro-entrepreneurs. This study employs a stratified random sampling technique to collect data from women micro-entrepreneurs who attended business coaching sessions. In total, 261 questionnaires were distributed and collected. This study has divided the moderator (i.e., perceived usefulness of business coaching) into two groups, namely, group 1 (with a low mean) and group 2 (with a high mean) for moderation analysis. By using a comparative analysis of the path coefficient for groups 1 and 2, the path is moderated by the perceived usefulness of business coaching if the beta value for group 1 is significant, and the beta value for group 2 is non-significant. The results show that eight out of a total of sixteen hypotheses were supported, while the remaining hypotheses were rejected. The findings of the study suggest that the domains of entrepreneurial competencies for women micro-entrepreneurs, including strategic, commitment, conceptual, opportunity, and relationship competencies, together with the perceived usefulness of business coaching, are vital for the business success and should remain the principal focus of future research in women entrepreneurship.

  • Purpose Compliance support system (CSS) aims to support employees' voluntary compliance activities, however, it requires a different approach from the acceptance of other general information systems. In other words, the user's concern that his/her compliance activities recorded in the system are monitored may hinder the active use of the system. In this regard, we set up a research model to investigate the factors that affect the intention to use CSS, by including perceived usefulness, compliance commitment, and surveillance concern. Design/methodology/approach A questionnaire survey was conducted for the employees of a domestic oil-company, who operates their own CSS. Based on the 865 data collected, a structural model analysis using PLS was conducted. As a result, all four hypotheses were accepted. It was found that perceived usefulness of CSS has a positive effect on the intention to use CSS. Compliance commitment has a positive effect both on perceived usefulness and intention to use CSS. In contrast, surveillance concern of one's non-compliance recorded in the CSS was shown to have a negative effect on the relationship between compliance commitment and perceived usefulness. Findings This study has academic implications in that it extends the viewpoint of the existing technology acceptance mechanism by examining the two aspects, i.e., compliance commitment and surveillance concern. This study may also provide practical directions to strengthen the use of the active compliance support system by the employees.

  • This research was conducted to find out about the effects of a perceived usefulness and a perceived ease of use on the viewer's attitude and their intention to use of the Terrestrial UHD Broadcasting. The survey was conducted with 191 respondents while innovativeness, relative advantage, active engagement, accessibility and affinity were considered as the external variables for this research. As the result shows, the external variables that affect the perceived usefulness are affinity, relative advantage, and innovativeness. However, it was confirmed that the accessibility has no major effect on the perceived usefulness. Among the external variables, the innovativeness has the highest level of effectiveness on the perceived usefulness of UHD broadcasting. Relative advantage, active engagement, and affinity were followed in orderly fashion. Especially, the perceived ease of use on UHD broadcasting has a major effect on the perceived usefulness. Also, the perceived usefulness affects the viewers' attitude and their intention to use. And the research verified that there is no correlation between the perceived ease of use vs. attitude and between attitude vs. intention to use. Therefore, we can safely say that the perceived usefulness of UHD broadcasting has main effects on viewers' attitude and their intention to use of UHD broadcasting.
