Increasing use of computers and networks in business, government, recreation, and almost all aspects of daily life has led to a proliferation of sensitive data about people and organizations. Without proper precautions, these sensitive data can be misused, misinterpreted, or mismanaged. The PORTIA project aims to develop a comprehensive, end-to-end technological infrastructure for handling sens...

The purpose of this chapter is to introduce and discuss organizational process modeling (OPM). This is a modeling approach developed for use in the design of IT systems. It is one part of a broader process approach described by Warboys, et al. [1]. The associated ProcessWeb technology, with its executable process modeling language (PML), provides the technological infrastructure. The whole set ...

Healthcare institutions have been outsourcing their IT infrastructure to the cloud. This new paradigm has financial and technological advantages. However, it has also associated some important issues. In the medical imaging field, studies typically involve high volumes of data, leading to increased communication latency in remote access environments. In this context, this paper presents a long-...

Machine-to-machine (M2M) communications emerge to autonomously operate to link interactions between Internet cyber world and physical systems. We present the technological scenario of M2M communications consisting of wireless infrastructure to cloud, and machine swarm of tremendous devices. Related technologies toward practical realization are explored to complete fundamental understanding and ...

Despite the Internet's increasing importance, there is little social scientific work that addresses its diffusion. Our knowledge is especially limited with respect to the conditions that encourage its spread across nations. This paper takes a first step in explaining the differences in Internet connectivity among OECD countries. After examining the impact of economic indicators, human capital, ...

In this paper we discuss the main challenges faced by electronic government initiatives. First, the components of and the demand for electronic government services are identified. Then we point out infrastructure requirements on the technological level for both the service providers and the customers. Organizational challenges are discussed with a focus on integration and coordination requireme...

Two major properties will characterize networks in the future: ‘3C everywhere’ and ‘physical interaction’. These two properties promises a computing infrastructure that seamlessly and ubiquitously aids users in accomplishing their tasks and that renders the actual computing devices and technology largely invisible. This paper begins by sketching pervasive computing scenarios. Next, we delve dee...

Proponents of accountable care organizations (ACOs) – consortia of hospitals and physicians that take responsibility for the cost and quality of care – assert that ACOs have the potential to improve patient health while reducing the waste in the healthcare system. But, for the fledgling ACOs to gain traction and begin to achieve that potential, they must build a new kind of technological infras...

E-Ticketing is recognized as one of the online shopping facilities provided by Malaysian companies to consumers. It was pioneered by Air Asia, low budget Airline Company, and its usage has increased with the rapid growth of technological infrastructure and Internet usage. This study aims to identify e-ticketing trends among urban communities. In addition, the characteristics of e-ticketers and ...
