Innovations in services continue to be a vital topic. Compared to product innovation, service innovation has received less attention in the literature. Studying service innovation is as important as ever especially since the world economy is shifting from a manufacturing economy to a service economy. Analytical and detailed discussion about service innovations is only beginning. This study aims...

This paper measures the size and structure of the U.S. information economy in 1992 and compares them with Marc Porat’s measures for 1967[4]. It also examines the magnitude and growth of the information components of the service sector over the years. The results of this study highlight the importance of information in the U.S. economy. It also documents interesting facts about the growth and co...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

The transformation of modern economies into predominantly service-based economies is happening on a global scale. While services are not new, the scale and complexity of globally dispersed services are growing rapidly. These transformations are enabled by—and often dependent on—information technologies and are fueled by processes of globalization. Transformational change provides opportunities ...

Cloud services today are increasingly built using functionality from other running services. In this paper, we question whether legacy Quality of Services (QoS) metrics and enforcement techniques are sufficient as they are producer centric. We argue that, similar to customer rating systems found in banking systems and many sharing economy apps (e.g., Uber and Airbnb), Quality of Consumption (Qo...

Still, the service remains inefficient and incapable of reforming itself, let alone the rest of the economy. Corruption has become an endemic feature of public sector activities, with the oil booms and busts distorting the incentive structures of civil servants and...

Infrastructure as a Service (IaaS) offers hardware resources (computing power, storage and network) as a service to its customers. The customers order these resources in the form of a lease. Aim of any service provider is to make a leasing plan to maximize the number of accepted leases. Opennebula is popular open source toolkit for building IaaS cloud. Opennebula has its own lease manager and i...

In light of the massive developments in Information Technology (IT) in the past few years, there has been a recent debate in the literature on the economic impact of IT. Of particular interest has been the role of the ‘New Economy’ sectors (hardware, software, and communications) in bringing about economic growth and productivity revival in the United States. While on a much smaller scale, Egyp...
