The Internet, and more recently mobile phones, has seen tremendous growth over the past few years. This paper examines the adoption of the Internet and WAP-enabled mobile phones in Singapore. Specifically, we examine the profile of Internet users, Internet activities and issues relating to WAP-enabled mobile phones. The results provide researchers and practitioners with some insights on the ado...

The improvement of wireless technologies and the increasing spread of mobile phones open new possibilities to perform mobile Customerto-Customer commercial activities. In this new scenario, where users cannot rely on stable connections, it assumes a great relevance how to trust the counterpart in a transaction and how to avoid that a disconnection, possible in wireless connections, can encourag...

During recent years there has been increasing public concern on potential cancer risks from microwave emissions from wireless phones. We evaluated the scientific evidence for long-term mobile phone use and the association with certain tumors in case-control studies, mostly from the Hardell group in Sweden and the Interphone study group. Regarding brain tumors the meta-analysis yielded for gliom...

W ith users increasingly adopting Internet-enabled cellular phones and other hand-held devices, vendors are looking for platform-independent wireless technologies to help these devices effectively access Internet content and services, and communicate with each other. Providing this access is particularly challenging for handheld devices because of their small screens, low memory and power, and ...

Background: Nowadays, mothers are continuously exposed to different sources of electromagnetic fields before and even during pregnancy.  It has recently been shown that exposure to mobile phone radiation during pregnancy may lead to adverse effects on the brain development in offspring and cause hyperactivity. Researchers have shown that behavioral problems in laboratory animals which have a s...

A lthough the Inter-net offers access to information sources worldwide, typically we do not expect to benefit from that access until we arrive at some familiar point—whether home, office, or school. However, the increasing variety of wireless devices offering IP connectivity, such as PDAs, handhelds, and digital cellular phones, is beginning to change our perceptions of the Internet. To underst...
