The use of mobile technologies in higher education seem to be lagging those in other service sectors, which have been quick to utilize the advantages that mobile communications have to offer. Based on the Technology Acceptance Model (TAM), this study analyzes the range factors and the level of influence on undergraduate intention to use a proposed...

This paper models the diffusion of mobile telephone subscriptions in Peru. Peru's mobile telephone diffusion has occurred in a concentrated market with relatively high prices and as such it features consumer behaviors such as call management, multiple subscriptions and handset sharing. The study uses two growth models, the Gompertz and the Logistic...

Purpose Although various practices to facilitate organizational change are proposed in the literature, very little is known about how these practices impact on ITIL adoptions. Therefore, the purpose of this study is to address this gap in the literature by offering insights on how change management practices impact on levels of ITIL compliance. De...

Many studies have been made on the diffusion and development of broadband, however there are few published studies on the critical factors for advancing broadband services in developing countries. Thus, the purpose of this paper is to understand and identify the critical success factors for the development of broadband services in a developing coun...

This case study provides a realistic, current, and detailed view of an outsourced software development project in a state agency which expects to have an integrated information system within six months. The case focuses on aspects of human resources and communications management that have not been properly undertaken, mainly due to lack of experien...

In this paper, we propose a distributed algorithm for one-to-all broadcasting on the arrangement graph. The algorithm exploits the rich topological properties of the (n, k)-arrangement graph to constitute the broadcasting binary tree and works recursively. When faulty links are encountered, the concepts of node-disjoint paths and virtual paths are...

Los avances en Internet y redes inaldmbricas y el rapido crecimiento del ntimero de equipos moviles han resultado en el crecimiento acelerado del comercio movil. Consideramos el comercio mévil como un subconjunto del comercio electrénico en el que las transacciones se realizan utilizando un terminal movil y una red inalambrica. El usuario de equipo...

With the advent of VLSI, a number of projects have been initiated to design large multiprocessor systems with more sophisticated interconnection networks, in order to reduce the communication time among processors. In fact, with the availability of faster processors and larger memories on a single chip, such multiprocessor systems are already comme...

We consider only the case of faulty links, but it can be extended to the case of faulty nodes by following a similar procedure. Our algorithm has two novel features: it looks for not only optimal paths but also near-optimal paths, and it intends to find an optimal node mainly. We believe that it is a useful tool for improving the efficiency of rout...

Advances in Internet and wireless access network technologies and the rapidly growing number of mobile personal devices, that has already exceeded one billion in the world, result in the fast growth of M-commerce. .. We view M-commerce here as a subset of E-commerce, where the transactions are conducted using a mobile terminal and a wireless access...
