Using a unique data set on public cloud infrastructure services consumption by 15,076 firms over the period from March 2009 to October 2011, we address the question of how a provider’s technical support influences cloud demand. The provider’s customers can choose (and switch between) two levels of support, basic and managed, which differ in the extent to which the provider helps customers adapt...

The design and development of computer support for work environments must consider both the coordination of individual activities and the collaboration that occurs among individuals in organizations. This paper presents our research e orts towards the understanding, design and implementation of a technological framework designated by \augmented work environments". These e orts build bridges bet...

A case study is discussed which shows the steps a beef producer group is taking towards electronic commerce. The group intends to use electronic communication for group interaction, feedback in the supply chain, and marketing. The case study is interpreted in terms of Rogers’ (1983, 1995) theory of diffusion of innovations. Electronic commerce is seen as an innovation which is perceived as havi...

I Acknowledgements This thesis emerged from my time as a research assistant at the Intelligent Sensor Actuator (ISAS) lab at the Karlsruhe Institute of Technology (KIT). During my work on this thesis, I was supported by many people in various ways. At this point, I would like to appreciate especially those mentioned below. First and foremost, my deepest gratitude goes to Uwe D. Hanebeck for adv...

We develop a procedure for implementing an efficient and envy-free allocation of m objects among n individuals with the possibility of monetary side-payments. The procedure eliminates envy by compensating envious players. It is fully descriptive and says explicitly which compensations should be made, and in what order. Moreover, it is simple enough to be carried out without computer support. We...

This paper presents a relatively new direction of CSCL research: small-group learning in the classroom. This research direction has received relatively little attention within the CSCL community. In this paper we explore the possibilities of collaborative technology in the classroom. We use the distinction between task-related and social-emotional interactions as a criterion for computer suppor...

Recently, investment in high technology companies boomed as people invested large sums of money even when there was little chance of the company being profitable. This is contrary to classical beliefs that investors have rational expectations and maximise their utility. Instead we must consider the idea that people are irrational and make decisions for many reasons, few of which involve a judic...

The owners/operators of complex assets such as production systems, military equipment and power stations aim to achieve high reliability with financial sustainability over long periods of time, and rely on a combination of internal and external socio-technical support systems to achieve this. Changes in the operational environment and technological advances may stimulate the need/opportunity fo...

In this paper, the authors use a mixed methods study, including a survey and follow up interviews, to investigate the concerns that elementary educators in a school district in British Columbia have regarding the diffusion and integration of Information and Communication Technologies (ICT) in their teaching. The research participants identified four major categories of concerns: the philosophy ...
