The advancements in virtualization technologies have provided a large spectrum of computational approaches. Dedicated computations can be run on private environments (virtual machines), created within the same computer. Through capable APIs, this functionality is leveraged for the service we wish to implement; a computer power service (CPS). We target peer-to-peer systems for this service, to exploit the potential of aggregating computing resources. The concept of a P2P network is mostly known for its expanded usage in distributed networks for sharing resources like content files or real-time data. This study adds computing power to the list of shared resources by describing a suitable service composition. Taking into account the dynamic nature of the platform, this CPS provision is achieved using a self stabilizing clustering algorithm. So, the resulting system of our research is based around a hierarchical P2P architecture and offers end-to-end consideration of resource provisioning and reliability. We named this system μCloud and characterizes it as a self-provisioning cloud service platform. It is designed, implemented and presented in this dissertation. Eventually, we assessed our work by showing that μCloud succeeds in providing user-centric services using a P2P computing unit. With this, we conclude that our system would be highly beneficial in both small and massively deployed environments. / KMBT_223 / Adobe Acrobat 9.51 Paper Capture Plug-in

Intrusions, or interruptions by others, are a common phenomenon in the modern workplace (Grove, 1983; Jett & George, 2003), particularly in the computing and information-technology (CIT) industry, as cross-specialty, and cross-team collaborations become more common (Beck et al., 2001). The present study examines the relationship between day-to-day intrusions (measured Monday, Tuesday, and Wednesday) and strain reactions and perceived job performance over the week (measured on Thursday) among 150 CIT employees. Using a number of resource-based theories (i.e., Conservation of Resources, Ego Depletion Model, Cognitive Fatigue Model), I hypothesize that participants experiencing more frequent intrusions on a day-to-day basis will experience greater levels of overall strain reactions (i.e., fatigue, self-regulation failure, and cognitive failure), and lower levels of overall perceived job performance for the week. To test these hypotheses, I applied a micro-macro multi-wave design, such that intrusions were measured at the end of three consecutive workdays (Level-1 Predictors) and strain reactions and performance measured on the fourth day (Level-2 Outcomes). Using Structural Equation Modeling and the technique put forth by Croon and van Veldhoven (2007), I specified four models to test my hypotheses, wherein level-1 variables (i.e., day-to-day intrusions) predicted level-2 outcomes (i.e., week-level fatigue, self-regulation failure, cognitive failure, and perceived performance). I found that day-to-day intrusions were significantly positively associated with fatigue, self-regulation failure, and perceived performance. However, day-to-day intrusions were not significantly associated with cognitive failure. These results suggest that intrusions may consume time and self-regulatory resources but may not consume cognitive resources, and that although intrusions cause impairment from a physical and self-regulatory perspective, they may not inhibit cognitive functioning. Future research should further investigate the relationship between intrusions and cognitive functioning. The present study is one of the first to explicitly study intrusions and recognize it as a stressor that influences both strain and performance variables. This is critical as intrusions become a more prominent fixture in the American workplace. This study also contributes to our understanding of the use of micro-macro approaches to statistical analyses, and provides additional insight into how occupational health psychologists can test long-held assumptions; namely day-to-day stressors contribute to long-term strain.
