Through fine-tuning the research model developed by Jahn and Kunz (2012) which is grounded on the Uses and Gratifications Theory, we conducted a qualitative study through interviewing consumers who participated in fan pages. Based on their responses in the interviews, we reconfirmed that content-oriented needs and social interaction value of relationship-oriented needs had positive impacts on fan page usage intensity and fan page engagement, respectively. Plus, we discovered that content-oriented needs had a positive impact on fan page engagement. The theoretical contributions, managerial implications of this study are also discussed.

These technologies not only strengthen the communication between instructors and learners, but also let the learners get an easily access their course materials at anytime and from anywhere. As a result, many educational institutes, including formal universities and online educational service providers, are now using E-learning technologies to deliver their courses as pure online courses or hybrid courses. In this research, the effectiveness of using online discussion forum in teaching is evaluated based on five teaching criteria related to knowledge construction process: learner's motivation, learner's independence, learner-learner interaction, learner-instructor interaction, and learner's satisfaction. The author's findings indicated that IT majors are more positive towards the use of online discussion forum in E-learning.

In particular, we develop a theoretical model by blending cutting-edge research in consumers’ trust, value co-creation, and eWOM to study how these factors interact with each other through a systematic review. From the theoretical analysis, we note that eWOM has a direct impact on purchase intention, and has an indirect impact on purchase intention which is moderated by consumers’ trust on the underlying product. eWOM also has an impact on value co-creation, and value co-creation has an effect on purchase intention. Consumers’ trust on a product has an impact on value co-creation, and the message source in the SNSs moderates the impacts of eWOM on consumers’ trust on a product, value co-creation, and purchase intention. This study provides a theoretical ground for future empirical research into issues related to the inter-relationship between value co-creation and eWOM within the SNS context. Practitioners can also develop a deeper understanding on developing SNS-based customer relationship management strategy from this work.

Although there is a large body of research on the favorable effects of web personalization on influencing online users' decision making, it is often assumed that web personalization functions well. Only scant research examines the adverse outcomes of web personalization on online users' perceptions and behavior when the personalized services malfunction. This research aims to fill this gap. Specifically, we examine malfunctioning personalized services that produce irrelevant and biased product recommendations in online shopping. Irrelevant recommendations are offerings not matched to online users' preferences, whereas biased recommendations are offerings generated for the merchant's interests. When online users encounter such malfunctioning personalized services, they may distrust the personalization agent, which influences their interactions with the agent. We drew on distrust theories to develop six hypotheses. To test the hypotheses, 245 participants were recruited for a field experiment in which they were tasked to download free music tracks from a personalized music download website. Our findings indicate that both irrelevant and biased recommendations lead to high distrust in a personalization agent's competence and integrity. Competence distrust, but not integrity distrust, in a personalization agent negatively influences online users' interactions with the agent.

In particular, the authors focus on how the electronic marketplace modifies its interface redesign for addressing the different tastes of users from different cultural backgrounds. The authors hope this study can address to how cultural and language differences affect the interface redesign of CRM, which is part of the enterprise system, in the multinational and global context through a qualitative study.

To gain a better understanding on whether the findings of these adoption studies can be generalized in other regions, and in particular, those communities with a small population and have a unique cultural background, the author revisits the third generation (3G) wireless adoption service issue using data collected from Guam. The result shows that the people on Guam have a different 3G wireless service adoption behavior compared with the people from Hong Kong. It is noted that perceived enjoyment plays a mediator role between the impacts of perceived service availability and social influence on the adoption intention. This result helps researchers and practitioners to gain insight for conducting adoption study for communities with a different cultural background, where their information and communication technology infrastructures are rapidly developing.

This study probes into this issue using the Innovation Diffusion Theory (IDT) (Rogers, 1995) along with two other constructs, i.e., subjective norms and perceived security on 3G mobile service. Using survey data collected from the youth of Hong Kong, the author notices that observability and complexity are IDT factors that affect the intention to adopt 3G mobile service by experienced users, i.e., who are current users of 2G or 2.5G mobile service. Plus subjective norms and perceived security are factors considered by both experienced and inexperienced users. Recommendations are provided to mobile service operators and developers in developing their rollout strategy in the mobile service market.

We propose a conceptual model where culture and product categories are two important factors on the level of use of BIN auctions. Our empirical investigation shows that the level of use of BIN auctions can be explained by the Hofstede Cultural Dimensions. While power distance brings a positive impact, uncertainty avoidance and individualism bring negative impacts on the level of use of BIN auctions by sellers of different countries. Our result also shows that the level of use of BIN auctions by sellers increases with the ease of judging product quality. Our results provide valuable insights for marketplace operators to refine their business strategies and market mechanisms for expanding their businesses to overseas markets.

During this period, the HKSARG launched its first IT Strategic Plan, Digital 21 IT Strategy, which provides the roadmap for the IT development for the city. In this eight-year period, the HKSARG committed about US$1,100M on various types of e-government projects. New e-Government applications and portals, such as Electronic Service Delivery (ESD) and Central Cyber Government Office (CCGO), were developed and rolled out from 2000 onwards to facilitate electronic transactions between the HKSARG and its external (business firms and citizens) and internal (government departments and employees) customers.

The primary focus of this strategy was to build up capabilities and infrastructure to support a thriving information economy, and to create a strong foundation for business growth and governmental service expansion in the use of IT. Hypotheses are formulated to test research concepts from Information Systems related to technology adoption. We find that managerial issues, rather than technological problems, led to the low adoption rate. Implications of our findings from a practitioner's perspectives are discussed.

The changes in linewidths in different solvents are attributed to ion-solvent interaction. Excellent correlations were established between the square root of the viscosity-normalized linewidths and their respective cobalt chemical shifts. It was also established that the cobalt chemical shifts and linewidths were sensitive to the electronic structure of the oxygen in the solvents. It is suggested that the origin of the electric-field gradient at cobalt arises from the distortion of the electronic structure through donor and acceptor interaction with solvent molecules. In other words, the Deverell electronic distortion model is favored over the electrostatic model. This conclusion is supported by good correlations of the cobalt-59 chemical shifts with the acceptor number of the solvents.

Prior research often examines the effectiveness of m-learning; however, it overlooks that learners with different characteristics may respond to m-learning differently. This research examines how learners with different personalities react to m-learning messages. Specifically, it uses the Myers-Briggs Type Indicator (MBTI), which is one of the most
widely-used personality instruments, and uses four dichotomies, namely introversion–extroversion, sensing–intuition, thinking–feeling and judgment–perception, to describe learner personalities. We conducted a 10-week study with 217 students. We used MBTI to categorize these 217 participating learners into sixteen personality groups, and sent short text messages to their mobile devices. These messages stimulated them to access lecture materials and to participate in online class discussions. We observed how learners with different personalities responded to text messages, and confirmed that learners of different personalities showed different levels of responses to m-learning messages.

It has the potential to provide interesting and relevant learning experiences to learners. Firms and education institutes explore the use of mobile devices to facilitate teaching and apprehension. This study proposes to use one of the simple functions of mobile phones, i. e. text messaging, as a tool to stimulate learners to access course materials. This study also examines whether users' personalities influence their reactions to learning via text messaging. Specifically, we used a personality instrument, Myers-Briggs Type Indicator (MBTI), to categorise learners. We conducted an experiment with 78 students, who received text messaging to remind them to access lecture materials for two weeks. We found that extroverts more often followed text messages to participate in discussion learning activities than introverts, and students of a judging type who liked well-defined learning schedules often followed the text messages to work on their learning schedules. A learner's personality does have an effect on the amount of learning they are prepared to participate in, when they respond to mobile text messaging.

We invited users of the G2C E-government Portal of Hong Kong to participate in an online experiment and collected data from 1,795 subjects. From our conjoint analysis, we find that monetary reward has the most significant impact on consumers’ utility among the six design attributes of E-payment Gateways investigated in this study, i.e. monetary reward, online transfer of information, acceptability, buyers’ protection excess, anonymity, and physical control. We also observe that there is a gender impact on the relative importance of these attributes.

In this research, we investigate the impact of trust on two different E-payment gateways, viz. online credit card payment system and the hypothetical online Octopus card (a stored-value smart card) payment system. Based on the model developed by Gefen et al. (2003) and McKnight et al. (2002a), we synthesize our own research model by incorporating disposition to trust, and trust and its antecedents with the Technology Acceptance Model (TAM). An online survey was conducted on the Government-to-Citizen (G2C) E-commerce
portal of the Hong Kong Government and 2,481 usable responses were collected. The empirical result shows that consumers in Hong Kong are using different trust building processes to consider their adoption for E-payment gateways."

The 3G mobile services include services like peer chatting, mobile games and movie download. While many studies explore why individuals adopt 3G mobile services, most of them consider 3G adoption to be a new technology adoption. Will users’ experience on older version of mobile services (e.g. 2G and 2.5G) influence their adoption decision on their 3G adoption? Hypotheses linking variables based on diffusion innovation technology and user’s mobile services usage background were developed. We conducted a survey and collected 175 responses. Our findings establish that different factors affecting users who have used the older version of mobile services and users’ decision to use or not to use 3G mobile services is a service upgrade decision, rather than an adoption decision.

They invest many resources in personalization to provide personalized services of higher quality in the hope of more business opportunities and higher customer satisfaction. Despite the proliferation of personalized web services worldwide, prior research on how personalization attracts users to switch to a personalized website is minimal. If this question is left unanswered, online firms do not know whether their investment can be justified. Our research examines how users' web experience and their perceptions towards personalization influence their attitudes towards switching to two types of personalized websites, online shopping websites and search engines. A survey study with 192 Internet users was conducted. The findings show that personalization plays different roles of attracting users in the context of search engines and online shopping sites. Internet users want useful personalized services, but at the same time, they are concerned with the manner in which firms use their data for personalization. If the involvement of Internet users with their current site is high, then personalized services are not attractive enough to motivate them to migrate from one site to another.
