Agency as discursive practice: from 'nobody' to 'somebody' as an international student in Australia

As more and more students pursue an international education, there is a need to investigate how these students deal with the demands of their study programs in the new academic context. This paper introduces one such student, a Thai English teacher named Woody, and looks at the ways that he engaged with a Master of Education program in Australia. I analyse the transcripts of two interviews that I conducted with Woody in his first semester using Fairclough's model of Critical Discourse Analysis (CDA). The analysis is interested in the social and institutional demands that Woody identified as impacting on the course, and the strategic action that he took in response to them. I argue that by undertaking this action, Woody was 'working' as an agent of his own change. The analysis highlights a proactive and strategic engagement on Woody's part, a point that has been missed in much of the literature on the international student experience in Australia

Orthonormal basis functions for continuous-time systems and Lp convergence

In this paper, model sets for linear-time invariant continuous-time systems that are spanned by fixed pole orthonormal bases are investigated. These bases generalise the well known Laguerre and two-parameter Kautz cases. It is shown that the obtained model sets are everywhere dense in the Hardy space H_1(#PI#) under the same condition as previously derived by the authors for the denseness in the (#PI# is the open right half plane) Hardy spaces H_p(#PI#), 1<p<#infinity#. As a further extension, the paper shows how orthonormal model sets, that are everywhere dense in H_p(#PI#), 1#<=#p<#infinity# and which have a prescribed asymptotic order may be constructed. Finally, it is established that the Fourier series formed by orthonormal basis functions coverge in all spaces H_p(#PI#) and (D is the open unit disk) H_p(D), 1<p<#infinity#. The results in this paper have application in system identification, model reduction and control system synthesis.
