Exploring Chinese users’ acceptance of instant messaging using the theory of planned behavior,the technology acceptance model,and the flow theory

Instant messaging (IM) is a popular Internet application around the world. In China, the competition in the IM market is very intense and there are over 10 IM products available. We examine the intrinsic and extrinsic motivations that affect Chinese users’ acceptance of IM based on the theory of planned behavior (TPB), the technology acceptance model (TAM), and the flow theory. Results demonstrate that users’ perceived usefulness and perceived enjoyment significantly influence their attitude towards using IM, which in turn impacts their behavioral intention. Furthermore, perceived usefulness, users’ concentration, and two components of the theory of planned behavior (TPB): subjective norm and perceived behavioral control, also have significant impact on the behavioral intention. Users’ intention determines their actual usage behavior.     

Perceptions and use of electronic media: Testing the relationship between organizational interpretation differences and media richness

How do managers perceive and use media? Media richness theory (MRT) appears to provide persuasive answers to this, but does it work when electronic media is used? Surveys of Japanese managers showed that the perceptions of media, including electronic media, did not contradict MRT. But, even so, the use of rich media was found to be influenced more strongly by whether the media was traditional or electronic, with respect to organizational interpretation of its environment. The perception and use of electronic media may not correspond, though they have generally been assumed to do so.     

Participation in videoconferenced meetings: user disposition and meeting context

Although videoconferencing systems are increasingly becoming important in the support of geographically dispersed groups, there are few studies that identify the types of tasks that are most effectively performed within videoconferenced meetings. This study investigates the relationship between (a) technology quality and communication activity during videoconferenced meetings, and (b) the intention of participants to support subsequent meetings. The data consists of a sample (n=295) of participants in a group videoconferencing system trial conducted by twenty government departments and incorporated bodies. Meeting sessions involved real work activities chosen by each of the participating groups. The results show that perceptions about the quality of technology and the communication activity conducted during the session are significantly related to the intentions of participants to support the use of the technology. Contrary to what might have been presumed, the findings also sbow that a significant majority of the participating groups chose communication activities least suited to the processing capabilities of the videoconferencing media.     

The roles of group potency and information and communication technologies in the relationship between task conflict and team effectiveness: A longitudinal study

The effects of task conflict on group effectiveness are far from conclusive. In order to further clarify this relationship, a contingency approach has been suggested. In this context, the present study examines the roles of group potency and information and communication technologies (ICTs) in the relationship between task conflict and team effectiveness. The study involved 44 groups of 4 members each, working in two communication media. Twenty-two groups worked in a face-to-face condition, and the other 22 groups worked in a computer-mediated communication condition. The groups developed a project during four weekly sessions over a one-month period. The results showed that group potency moderated the relationship between task conflict and group effectiveness. However, the communication medium did not play a moderator role in these relationships.     

The complexities of electronic services implementation and institutionalisation in the public sector

Electronic service implementation (ESI) in the public sector attempts to improve efficiency, effectiveness, and transparency of governmental departments. Despite having provided the necessary infrastructure and investment, many governments have struggled to realise such aims due to the various forces that challenge implementation and institutionalisation. Using institutional theory as a lens, we explored the forces influencing the implementation and institutionalisation of ESI in the public sector. While our results reinforced previous research in IT implementation and organisational transformation, they showed that the dynamic nature of technology poses unanticipated pressures, and that these can impede the implementation and institutionalisation process.     

Cultural Effects on Use of Online Social Media for Health-Related Information Acquisition and Sharing in Taiwan

The aims of this study were to use the technology acceptance model to examine how the cultural characteristics of social media users in Taiwan affect their use of social media for acquiring and sharing health-related information and to examine how their use of online social media benefits their social relationships and health self-efficacy. The research model in this quantitative cross-sectional study was tested with data collected from 321 active Facebook users in Taiwan. All three cultural characteristics/dimensions considered in the research model (masculinity, collectivism, and uncertainty avoidance) significantly affected the perceived usefulness and the perceived ease of using the online social media platform. However, masculinity had a significant positive effect on perceived usefulness but not on perceived ease of use. These results imply that technology tools for people in high masculinity cultures should be designed to maximize the effectiveness of the technology for achieving goals rather than to maximize the ease of using the technology. On the other hand, the use of online social media for acquiring and sharing health-related information significantly affected the social relationships of users but not their health self-efficacy. The results of this study imply that participants in online communities share health-related information not only to enhance their health but also to form strong social connections. This study proposes a new construct of technology acceptance, acquisition, and sharing of health-related information and investigates its effects on social relationships and health self-efficacy.
