While exogenous events are commonly viewed as instantaneous actions occurring at specific time points and interacting with actions, they can sometimes be seen as enforcing earliest starting time and latest finishing time constraints on actions...

There are many distributed applications that Incorporate application-specific reliability algorithms which operate on top of general purpose networking. operating system and programming language facilities. We present a framework for application-level reliability testing suitable for a wide range of distributed applications, and desCribe how we've applied it to one particular application, Mercu...

Systematic operational quality improvement strategies within the NHS are hard to find, although there are numerous published reports of sporadic departmental models and methods resulting in improvements in clinical care. We describe the experience of devising a tool to provide large data collection of patient care experiences by using medical students to shadow patient journeys. This combines p...

This thesis introduces the Progressive Messages model of communication. It is an event-driven framework for building scalable parallel and distributed computing applications on modern networks. In particular, the paradigm provides notification of message termination. That is, when a message succeeds or fails, the user’s application can capture an event (often through a callback) and perform a d...

What are the technologies that will transform business and drive the research agenda for the IS field in the years to come? Which innovations, platforms, and paradigms will become dominant, and which others will ultimately pass into obscurity? In this panel discussion, we will seek answers to these questions from those with a unique and unmatched perspective. The leaders who have witnessed the ...
