Systematic social observation has been used as a health research methodology for collecting information from the neighborhood physical and social environment. The objectives of this article were to describe the operationalization of direct observation of the physical and social environment in urban areas and to evaluate the instrument's reliability. The systematic social observation instrument ...

In many real-world settings (e.g., interdomain routing in the Internet) strategic agents are instructed to follow best-reply dynamics in asynchronous environments. In such settings players learn of each other’s actions via update messages that can be delayed or even lost. In particular, several players might update their actions simultaneously, or make choices based on outdated information. In ...

This paper[4] describes a series of optimizations the authors performed on the Xen network IO subsystem. The original Xen virtualization architecture was introduced in [2]. The idea of separate I/O domains was described in [3]. This work was able to achieve significant performance gains in both transmit and receive throughput by employing a range of hardware and software optimizations. Most of ...

This multi-site, quasi-experimental study examined the performance outcomes of nurses (n = 152) in a military nurse transition program. A modified-performance instrument was used to assess participants in two high-fidelity simulation scenarios. Although results indicated a significant increase in scores posttraining, only moderate interrater reliability results were found for the new instrument...

This paper further develops an architecture and design elements for a resource management and a signalling system to support the construction and maintenance of a mid-long term hybrid multicast tree for multimedia distribution services in a QoS guaranteed way, over multiple IP domains. The system called E-cast is composed of an overlay part – in inter-domain and possible IP level multicast in i...

The time between transmitting symbols (the inter-symbol delay) governs the speed at which the link operates. The shorter the inter-symbol delay, the faster the link operates. However, if the inter-symbol delay is too short, then symbols may not arrive at the receiver intact, or in-order. If two symbols are transmitted on the same wire in quick succession, then the resulting pulse may be too sho...
