Geoff Harcourt : his life and times in Adelaide
No full textTalk recorded at the University of Adelaide, Ira Raymond Exhibition Room, Barr Smith Library, Thursday 10 May 2007, at a free public talk hosted by the Friends.Born in Melbourne in 1931, Geoff Harcourt graduated B. Comm. and M. Comm. at the University of Melbourne, and then went on to graduate as a PhD at Cambridge University. He returned to Australia in 1958 to take up a Lectureship at the University of Adelaide, where he was appointed to a Personal Chair in 1967. In 1982 he accepted a Fellowship at Jesus College, Cambridge, and a lectureship in Economics, and was subsequently promoted to Reader in the History of Economic Theory at Cambridge. Geoff Harcourt, a Keynesian economist in the broadest sense, is one of the few Australian economists whose writings have been absorbed by the leading economists of his generation
Energy managed reporting for wireless sensor networks
No full textIn this paper, we propose a technique to extend the network lifetime of a wireless sensor network, whereby each sensor node decides its individual network involvement based on its own energy resources and the information contained in each packet. The information content is ascertained through a system of rules describing prospective events in the sensed environment, and how important such events are. While the packets deemed most important are propagated by all sensor nodes, low importance packets are handled by only the nodes with high energy reserves. Results obtained from simulations depicting a wireless sensor network used to monitor pump temperature in an industrial environment have shown that a considerable increase in the network lifetime and network connectivity can be obtained. The results also show that when coupled with a form of energy harvesting, our technique can enable perpetual network operatio
Composing after cage
No full textThis thesis alms to identify and explore the ideas of John Cage, then looks at their impact on and absorption by a variety of American composers. This in turn provides the context for my own compositional work which forms the main substance of this submission and which is presented on compact disc (accompanied
by indicative scores). The source material for the second half of the thesis comes largely from my own book of interviews with composers, American Originals (co-authored with Nicola Walker
Smith), which is included as an appendix
Using and evaluating CASE tools : from software engineering to phenomenology
No full textCASE (Computer-Aided Systems Engineering) is a recent addition to the long line of
"silver bullets" that promise to transform information systems development, delivering
new levels of quality and productivity. CASE is particularly intriguing because
information systems (IS) practitioners spend their working lives applying information
technology (IT) to other people's work, and now they are applying it to themselves.
CASE research to date has been dominated by accounts of tool development,
normative writings (for example practitioner success stories) and surveys recording
IT specialists' perceptions. There have been very few in-depth studies of tool use,
and very few attempts to quantify benefits, therefore the essence of the CASE process
remains largely unexplored, and the views of stakeholders other than the IT specialists
have yet to be heard.
The research presented here addresses these concerns by adopting a hybrid research
approach combining action research, grounded theory and phenoinenology and using
both qualitative and quantitative data in order to tell the story of a system developer's
experience in using CASE tools in three information systems projects for a major UK
car manufacturer over a four year period. The author was the lead developer on all
three projects. Action research is a learning process, the researcher is an explorer.
At the start of this project it was assumed that the tools would be the focus of the
work. As the research progressed it became evident that the tools were but part of
a richer organisational context in which culture, politics, history, external initiatives
and cognitive limitations played important roles. The author continued to record
experiences and impressions of tool use in the project diary together with quality and
productivity metrics. But the diary also became home to a story of organisational
developments that had not originally been foreseen.
The principal contribution made by the work is to identity the narrow positivistic
nature of CASE knowledge, and to show via the research stories the overwhelming
importance of organisational context to systems development success and how the
exploration of context is poorly supported by the tools. Sixteen further contributions
are listed in the Conclusions to the thesis, including a major extension to Wynekoop
and Conger's CASE research taxonomy, an identification of the potentially
misleading nature of quantitative IS assessment and further evidence of the limitations
of the "scientific" approach to systems development.
The thesis is completed by two proposals for further work. The first seeks to
advance IS theory by developing further a number of emerging process models of IS
development. The second seeks to advance IS practice by asking the question "How
can CASE tools be used to stimulate awareness and debate about the effects of
organisational context?", and outlines a programme of research in this area
