This research investigates factors influencing the willingness to pay for and consume mobile-online gaming services given varying levels of availability and usage of electronic cash technology. A sample of 9299 cases was surveyed and collected in Hong Kong comparing the influence of electronic cash availability on the willingness to pay for and consume mobile-online gaming services controlling for gender, age and education level. Our research found that electronic cash technology had almost no influence on men’s’ game usage while for women, the availability of electronic cash was a significant enabler of online game usage, and that age affected the degree of influence — electronic cash technology use among children and adolescents had almost no influence on game usage, but was influential in motivating more game usage in older gamers. Differences in educational level also impacted the effect of electronic cash availability on game usage, with those at the extremes, gamers with a primary only, or post-graduate education responding that electronic cash had almost no influence on their game usage, while gamers with secondary or college education tended to have electronic cash usage profiles closer to the average across all users.

This paper describes the platformisation of the mobile services domain, which in recent years has become a successful strategy for some hardware manufacturers and software companies. While pursuing diverging platform strategies and business models, they have succeeded in creating a demand for mobile software and content with end-users. Mobile network operators have lagged behind in this area and are now attempting to keep up with other initiatives. This paper explores the question which platform type an operator should adopt if he wants to play a meaningful role in the mobile service domain. It describes advantages and disadvantages of different platform types and lists some core competences an operator should have, or develop, in order to successful adopt a certain platform type.

The emergence of wireless communities offers an attractive alternative to operator-centric models for providing broadband wireless services. While the first attempts of purely self-organized communities have been limited by the difficulty of attracting enough members willing to share their resources with the community, newer hybrid wireless communities (where a firm supports and incentivizes individuals who share their infrastructure in exchange of being able to exploit the network) is developing rapidly. This difference suggests the importance of attracting and motivating members with suitable incentives. While this is widely recognized as a key issue, existing research is limited to pure communities and does not adequately cover hybrid communities. Our research project intends to address this shortcoming by focusing on hybrid communities, building an adapted theoretical model considering specific motivations and collecting empirical evidence using mixed qualitative and quantitative methods like content analysis, interviews and a large-scale survey. As this is a research-in-progress, only the first results of the project are shown, namely an adapted theoretical model and some evidence from a content analysis of hybrid wireless community forums. Participation appears to be motivated by tangible rewards (free network access, revenue sharing), social rewards (socializing with peers and feel part of a community), psychological rewards (pursuing idealistic goals and feeling competent) and intrinsic enjoyment, but hindered by participation efforts (monetary costs and required effort) and other concerns (security, legality and bandwidth use).

The convergence of mobile telephony networks with the Internet has resulted in an increasing number of conflicts – so-called tussles – between different stakeholders within the mobile network ecosystem. These tussles can be characterised by socio-economic as well as technical conflicts of interest, accompanied by concrete interferences and blocking activities leading to inefficiencies (e.g. through the deployment of parallel architectures) and network system failures. Infrastructure architects in the computer science discipline have developed the concept of "design for tussle" to deal with this phenomenon in the debate around the next-generation Internet. This paper applies the tussle concept in the context of mobile information infrastructure design. It argues for a systemic understanding of tussles based on Luhmann’s Theory of Social Systems. The paper discusses the introduction of mobile VoIP in the UK as an example of an emerging conflict system within the mobile network ecosystem. The empirical findings are based on an extensive case study conducted from 2007 to 2009. The case study includes 39 expert interviews aiming to illustrate the way in which these tussles in the context of mobile VoIP take place. The contribution of this paper to mobile information infrastructure design is a systems-theoretical tussle framework based on Luhmann's notion of conflict aiming to provide designers with a systemic understanding of tussles.

As a subset of e-commerce, m-commerce (mobile commerce) also faces problems of trust building. The limitation of mobile devices, such as screen size, privacy and safety problem, make it important to build trust effectively and efficiently. In e-commerce, culture can exert a significant impact on how trust is built through various web strategies. Similarly, trust-building strategies in m-commerce could also have different effects on people in specific cultures, because of the extent to which they favor in-groups versus out-groups. Given features of mobile technologies and growing popularity of social network media, it is interesting to investigate whether personalized trust building via social ties with consumers could be explored to transform entities viewed as out-groups into in-groups of consumers, and the extent to which such strategies are effective in different cultures. Three studies are planned to pursue this line of enquiry. The results could have important implications for scholars and practitioners to leverage on social ties to boost sales in m-commerce.

This study aims to explain the factors determining multiple subscriptions in the Swedish mobile phone market. A generalized Poisson model of count data from a national survey in Sweden finds that business subscriptions and house-hold size are the main predictors of the multiple mobile phone subscriptions, along with individual demographic characteristics such as, age, gender and type of occupation. Other factors such as education level, area of living, prepaid as the main subscription, as well as mobile Internet and fixed phone subscription are not significant. These facts indicate that business subscriptions and subscriptions for family are the main factors that determine the incidence of multiple subscriptions in the Swedish mobile phone market. The operator can gain from this situation by tightening the network effect to the existing sub-scribers. This can be done by encouraging them to have additional subscriptions from the same operator or intra-operator multiple subscriptions. For the regulator, this situation has to be taken into consideration when determining the Significant Market Power (SMP) since a larger market share does not always indicate actual market domination.

Using the example of Amazon’s Kindle 2 launch, this exploratory case study research investigates an emerging mobile business model in the eBook market that closely connects an innovative device with access to content. Reflecting on the business model and innovation literature, the paper points to the potential of an emerging mobile business model that relies on radical innovations to change industry structures combined with high uncertainty. Based on the case study of Kindle 2, the study reveals the need to align innovative products and services with a company’s overall brand strategy to avoid dilution. Finally, it suggests that a mobile business model based on a proprietary approach can be successful in the short run, its long run success depends on the ability to react to new market requirements and competitors. The paper concludes with a reflection of how business models need to be dynamically re-adjusted in such a fast moving field.

In this paper we describe a first investigation of continuous service for travel agencies that addresses an often neglected service part of a travel customer cycle: the trip itself. In a user-centred design process, we have developed a service and a system prototype to test our proposed design goals and system design, as well as the service in a realistic environment. We propose a three-level design consisting of an organizational, a user and a system level. As both the customer and agent participants indicate a high appreciation of the service and the system, both the implementation of live support on a trip and the motivational design of the prototype can be fruitful design solutions in developing new services providing continuous service provision in tourism.

Foreign students who live and study in China encounter many problems in Chinese language learning, as language learning often correlates with background knowledge which varies from country to country caused by cultural and social differences in terms of distinct public policies and services. With the increasing number of foreign students in China and the great demand for mobile Chinese language learning applications, this paper presents a context-based knowledge support system, which is a useful tool for foreign students to practice Chinese in the mobile environment. The contexts are adopted to construct student requirement profile, which is used for matching suitable knowledge support and Chinese materials for practice. The system framework is proposed, and the knowledge representation model and matching method are elaborated to indicate the functions of the system. Finally, a prototype of bank services is implemented.
