The purpose of this paper is to identify the factors that influence people to play socially interactive games on mobile devices. Based on network externalities and theory of uses and gratifications (U&G), it seeks to provide direction for further academic research on this timely topic.

Based on 237 valid responses collected from online questionnaires, structural equation modeling technology was employed to examine the research model.

The results reveal that both network externalities and individual gratifications significantly influence the intention to play social games on mobile devices. Time flexibility, however, which is one of the mobile device features, appears to contribute relatively little to the intention to play mobile social games.

This research successfully applies a combination of network externalities theory and U&G theory to investigate the antecedents of players’ intentions to play mobile social games. This study is able to provide a better understanding of how two dimensions – perceived number of users/peers and individual gratification – influence mobile game playing, an insight that has not been examined previously in the mobile apps literature.

Building upon studies of value theory and social psychology literature, the purpose of this paper is to empirically test a research model that incorporates antecedents of value (mobile convenience, service compatibility, security risk, and cognitive effort) and mobile value (utilitarian and hedonic value), and social influence (social norms and number of peers) to examine factors affecting user intention toward mobile social networking sites (SNSs).

The proposed model was empirically evaluated using survey data collected from 318 users on their perceptions of mobile SNSs. A structural equation modeling (SEM) was used to assess the relationships of the research model.

The results revealed that mobile convenience, service compatibility, security risk, and cognitive effort have a significant and indirect impact on the user acceptance of mobile SNSs through their respective paths on hedonic value and utility value.

Mobile SNSs practitioners should focus on enhancing users’ mobile value through perceived benefits, lower perceived costs, and simultaneously developing social influence to further boost users’ intention to use for mobile social networking services.

This study contributes to a theoretical understanding of factors that explain users’ intention to use the mobile SNSs.

The purpose of this paper is to provide an explanation of factors influencing online music purchase intention of Taiwanese early adopter of online music, which can help the online music practitioners of Taiwan to develop better market strategies.

An empirical survey was used to test the hypotheses. Data were collected from a total of 302 online Taiwanese early adopters of online music. A structural equation modeling (SEM) is proposed to assess the relationships of the research model.

The findings in this paper show that the perceived value of online music is a significant factor in predicting the purchaser intention of buying online music in Taiwan. Also, the beneficial factor of the perceived usefulness and playfulness are identified in addition to the sacrificing factor of the perceived price for assessing the value. Moreover, purchasers and potential purchasers differ in the determinants underlying the perceptions of value, which customers hold towards online music.

The results in the paper facilitate to understand what encourages and impedes the purchase intention of early adopters of online music in Taiwan.

The value of this paper is to establish a theoretical model incorporating the value‐intention framework into technology acceptance model to investigate the purchase behavior of early adopter of online music in Taiwan. The results of this study help online music practitioners of Taiwan and other Asian countries culture similar to Taiwan to create a success business model.

The paper's aim is to explore the factors that affect the online game addiction and the role that online game addiction plays in the relationship between online satisfaction and loyalty.

A web survey of online game players was conducted, with 1,186 valid responses collected. Structure equation modeling – specifically partial least squares – was used to assess the relationships in the proposed research framework.

The results indicate that perceived playfulness and descriptive norms influence online game addiction. Furthermore, descriptive norms indirectly affect online game addiction through perceived playfulness. Addiction also directly contributes to loyalty and attenuates the relationship between satisfaction and loyalty. This finding partially explains why people remain loyal to an online game despite being dissatisfied.

Online gaming vendors should strive to create amusing game content and to maintain their online game communities in order to enhance players' perceptions of playfulness and the effects of social influences. Also, because satisfaction is the most significant indicator of loyalty, vendors can enhance loyalty by providing better services, such as fraud prevention and the detection of cheating behaviors.

The value of this study is that it reveals the moderating influences of addiction on the satisfaction‐loyalty relationship and factors that contribute to the online game addiction. Moreover, while many past studies focused on addiction's negative effects and on groups considered particularly vulnerable to Internet addiction, this paper extends previous work by investigating the relationship of addiction to other marketing variables and by using a more general population, mostly young adults, as research subjects.

The following teaching case study details an exciting and modern case of an integrated circuit distribution company in Taiwan (the Sunnic Group) as it transitions through several major innovation initiatives creating new products and a new role for itself in the industry while simultaneously fending off market forces, competition, and degrading profits. This case study delivers important lessons about conducting innovation via four major areas. The first area details how market forces, intense competitions, entry barriers, and corporate growth can create situations where innovating on a large scale has strong advantages over the alternatives. The second area shows how theories on innovation and customer value propositions are used to create realistic strategies for new products and feasible plans for organizational change. Topics like knowledge management, creating new capabilities, and key performance indicators are discussed. Next, the actual implementations of several innovation initiatives are explained in dramatic fashion with characters demonstrating resistance to innovation, competitor's reactions, and conflicts of interest; more importantly, it demonstrates how product development strategies can actually play out. This section also captures how transforming an organization can be stressful, leadership intensive, and difficult. Finally, the case reviews the results of the transformation and innovation efforts via the patent and financial results. This case is designed to teach students a mix of theory and practical skills. A lengthy list of questions for students is also provided and a teacher's edition from page 21 onwards of this text contains lecture notes that help in guiding class discussions and aid in creating assignments.

To improve the likelihood of system success and user involvement, an MIS department manager has to deal with people and lead them under given user styles and organizational culture. For this reason, the managerial behaviour of MIS managers plays an important role in developing MIS. First introduces the managerial behaviours and a stage model of MIS growth. Finally, discusses the relationships between managerial behaviour and MIS development stages.

The purpose of this paper is to investigate the factors that influence the willingness of the public to adopt online tax filing services.

An online survey was conducted from which 400 valid questionnaires were recovered. The questionnaire data were used to research the degree of acceptance among Taiwanese taxpayers with regard to the online tax filing system. Respondents were classified into existing users (who were sub‐categorised into early adopters and late adopters) and potential adopters.

The results demonstrate that the perceived attributes of trialability and observability significantly influence the adoption intention of late adopters. However, these attributes did not have a significant influence on early adopters. Social norms and the perceived attributes of relative advantage, compatibility, and complexity significantly influence the adoption intention of current users. For potential adopters, only social norms had a significant effect on their intention to use the online tax filing system.

This study recommends that a more convenient and user‐friendly design for online tax‐filing processes would enhance the perception of the system and encourage taxpayers to continue or consider using this e‐government service.

While online tax‐filing systems are getting more attention in e‐government development, little is known about why people are willing to use them. This paper investigates the reasons by applying innovation diffusion theory, social cognitive theory and contingency theory. The results could be applicable to other e‐government services.

The purpose of this paper is to explore a conceptual model for analyzing customers' perceptions of using mobile commerce services for online shopping. This paper provides insights into consumer behavior, and the results have important implications for designers, managers, marketers, and system providers of mobile shopping (m‐shopping) web sites.

An empirical investigation was carried out to test the hypotheses. The samples include 369 professional participants. For testing the relationships of the model, structural equation modeling (SEM) is used.

The results demonstrate that anxiety, which is an affective barrier against using innovative systems, is a key negative predictor of a customer's intentions to use mobile phones. Also, the consumer's self‐perception of mobile skillfulness significantly affects anxiety, enjoyment, and usefulness. Furthermore, enjoyment, usefulness, and compatibility have an impact on a customer's behavioral intentions.

The findings of this study help to understand what hinders or encourages the m‐shopping intention of online customers.

The results not only help develop a sophisticated understanding of mobile commerce theories for researchers, but they also offer useful knowledge to those involved in promoting m‐shopping to potential purchasers. The value of the paper is that the results could be applied to other portable information technology service adoptions, such as personal digital assistants (PDA), smart phones, advanced mobile phones, and portable global positioning systems (GPS).

Virtual worlds are a typical form of social network syndication. Although the future of the virtual world phenomenon seems bright, not all efforts have succeeded. Therefore knowing how to motivate users and keep them continually engaged and visiting is an important challenge for those who create and manage virtual world websites. This paper aims to address these issues.

The present study proposes a conceptual model from technological, entertainment and social perspectives to examine the determinants affecting users' intentions in their virtual worlds usage. Recognising that human behaviour varies according to different social roles, this study investigated four social roles (habitual, active, personal and lurker), and 729 valid data samples were collected from the Chinese virtual world, i‐Partment. Partial least square and multi‐group analysis were performed to measure the research model.

The results of this study indicate that ease of use, usefulness, social presence and enjoyment are important factors of virtual worlds usage. This study also confirms that social presence and enjoyment are influenced by platform‐based and sociability‐based interactive quality, with sociability‐based interactive quality having a much higher impact on social presence than platform‐based quality. Moreover the proposed model demonstrates different intensities of explanatory power for users' usage intentions according to four social roles, and the results of this study indicate different but insightful findings for each of the four social roles.

The virtual worlds practitioners should strive to launch creative and new recreational information or functions on a regular basis to make users' experiences enjoyable. In addition practitioners should initiate special activities or festivals to promote social interaction and devise rules to encourage users to spend more time on the virtual world websites. Moreover virtual world websites must be easy to use – with a user‐friendly interface, smooth moving lines and clear and understandable information – and provide useful functions.

This paper is one of the few studies that compares and analyses the behavioural models of different social roles, and suggests that virtual world website practitioners should make use of these findings and provide flexible services to fulfil different users' special needs.

While many studies have focussed on web site stickiness, little is known about the antecedents of blog stickiness such as visit duration and user retention. How demographic differences affect the antecedents of blog stickiness is another research question. Based on social cognitive theory, the IS success model and individual differences theory, this study aims to explore blog quality, the need for cognition, and social influence as the antecedents of blog stickiness.

The subjects of this study were users who had blog reading experience. The structural equation modelling (SEM) approach was used to evaluate the research model.

After surveying 231 blog users, the results demonstrate that content is still king in the blog environment. Social influence affects the duration of visits to a blog, but not the retention to the blog. Female readers are mainly interested in content, while males are more interested in system quality and social influence. While blog veterans or heavy users care about content and social influence, blog “newbies” care about context and system quality. Students and non‐students also have different antecedents of blog stickiness.

This study increases understanding of blog stickiness and suggests avenues for future research.
