Answering SPARQL queries over the Web of Linked Data is a challenging problem. Approaches based on distributed query processing provide up-to-date results but can suffer from delayed response times, indexing-based approaches provide fast response times but results can be out-of-date and the costs of indexing the growing Web of Linked Data are potentially huge. Hybrid approaches try to offer the...

Current evidence demonstrates that even though some non-native listeners can achieve native-like performance for speech perception tasks in quiet, the presence of a background noise is much more detrimental to speech intelligibility for non-native compared to native listeners. Even when performance is equated across groups, it is likely that greater listening effort is required for non-native l...

Smartphones are innovations that currently provide immense benefits and convenience to users in society. However, not all the users of society are accepting and using smart phones, more specifically, for this research study older adults (50+) are a demographic group displaying such an attitude. Currently, there is minimal knowledge of the reasons that older adults adopt and use smartphones. Bea...

Prior research has characterized the adoption of process standards as a multi-stage effort ranging from the initial implementation through institutionalization. However, relationships between these adoption stages have not been examined significantly. In this study the author analyzes performance data from a large service provider that has implemented a process standardization framework for ser...

I n the preceding article, I proposed live delinitions of strategy -as a plan, ploy, pattern, position, and perspective. Drawing on these, I wish to investigate here the question of why organizations really do need strategies. In discussing some of the conventional reasons as well as other ones-to set direction, focus effort, define the organization, provide consistency-I will consider how thes...

A wide variety of applications, including traditional data transfer and adaptive real-time multimedia, can potentially use the ATM available bit rate service. While these applications all share the ability to adapt their rate, they otherwise may have very different characteristics. The goal of this paper is to examine routing algorithms in the context of two different classes of best-effort app...

The IT landscape in German hospitals is characterized by great heterogeneity. While IT-systems directly supporting medical diagnosis generally show high adoption rates, acceptance of process supporting systems, such as systems supporting the documentation processes, is often not as originally envisioned when the system was implemented. This research analyzes physicians’ perceptions towards adop...
