With the growing development of information technology and the wireless telecommunication network nowadays, mobile devices have been expanding rapidly and have been emerging as important tools for consumers. Using m-services and applications (apps) on mobile devices becomes custom in people’s daily lives. This study proposes a theoretical model to explore the continued usage behavior for smartp...

Providing Best-Effort Services in Dataspace Systems

eGovernment initiatives all over the world endeavor to integrate Information and Communication Technologies (ICT) to transform delivery of government services to their stakeholders by improving quality of services, accountability and efficiency. In this study we explore adoption of ICT to enhance government-to-employee interactions in a government organization in a developing country. We examin...

This paper deals with the impact of traffic handling mechanisms on capacity for different network architectures. Three traffic handling models are considered: per-flow, class-based and best-effort (BE). These models can be used to meet service guarantees, the major differences being in their complexity of implementations and in the quantity of network resources that must be provided. In this st...

Cellular networks, e.g. UMTS, provide voice and data services to mobile users. In hot spots where users need high speed data services operators can deploy low-cost high-speed WLANs, e.g. 802.11, to cover hot-spots. This paper proposes a possible architecture of integrating UMTS and 802.11 WLAN. The architecture allows a mobile node to maintain data (PS) connection through WLAN and voice (CS) co...

Does a performance measure which is a monotonous function of the benefit (a benefit measure) lead to a desirable allocation of effort between the tasks which create this benefit? We analyse two settings. If the mechanism designer knows the choice set of the agent, benefit measures generally do not result in the second-best effort allocation – unless restrictive assumptions about agent’s prefere...

In this paper we discuss technology appropriation in the context of close personal relationships. We review literature that reveals how collaborative appropriation is a natural and necessary feature of technology adoption by relational partners. We then advance a position whereby appropriations in close relationships can be characterised as a form of discretionary effort investment. We end by r...
