Supervision in an alternative paradigm
Original article can be found at: http://www.textjournal.com.au/speciss/issue6/content.htmIn this paper we express our framing of supervision as preparation and training for professional practice as a researcher, rather than the culmination of tertiary education. Instead of discussing the supervisory activity, performance and best practice, we focus on the uniqueness of practice as a researcher in the creative arts as being constituted by an emerging and novel research paradigm. We develop the theoretical framework of Guba and Lincoln, contrasting their use of the term âparadigmâ with that of Kuhn. We identify research in the creative arts as being a so-called âalternative paradigmâ but having its own unique characteristics. However, we claim that these characteristics are not discretionary but related to generic characteristics of research. By developing Guba and Lincolnâs model, we argue that the characteristics of research in the creative arts cannot simply be translated or inferred from the characteristics of research in cognate disciplines, but must be derived from the worldview and values of the arts community. This involves identifying both generic and discipline-specific characteristics. We claim that the discipline-specific characteristics reflect the values that are found in professional practice, and the generic characteristics reflect the values that are found in academic research across disciplines. As a result of establishing criteria for the evaluation of activities as research in a novel paradigm such as the creative arts, we present a critical framework for thesis production that facilitates the inclusion of the researcherâs own creative work in the doctoral study. A number of issues arising from the experience of the authors as supervisors and examiners are discussed. Finally, a template for a seven-chapter thesis in the creative arts is proposed, which addresses common problems such as weaknesses in the single-case study approach and researcher bias in participant-observation studies.Peer reviewe
Inferring a collective concept of research from the actions of the art and design research community
This article examines output types as manifestations of different concepts of research. We compare the UK academic scene to that of Brazil, identifying the former as responding âbottom-upâ to researcher needs and the latter determining âtop-downâ what researchers can do. Taking the UK model as indicative of what researchers think they need, we undertook a detailed analysis of the output types used in RAE2008 across all subjects in order to see which types were used and by whom. We also undertook a further analysis of the use of traditional, text-based formats in art and design, and the use of non-traditional, non-textual output types in other subjects. We conclude that both the journal format and the exhibition format are expressive of the understanding each community has of the meaning of research as an activity. This is further reinforced by the national structures within which research is undertaken and evaluatedPeer reviewedSubmitted Versio
A pedagogical proposal in an area of epistemological uncertainty
IV Projetar 2009: PROJETO COMO INVESTIGAĂĂO: ENSINO, PESQUISA E PRĂTICA FAU-UPM SĂO PAULO BRASIL, Outubro 2009In professional areas in which there is an element of design practice, such as architecture and urbanism, the academic model of knowledge has not been clearly articulated. This means that often the values held in professional practice run counter to the traditional models of knowledge and research that are adopted. As a result there is a problem in accounting for research in these areas in ways that will be recognised and valued by both communities. There is an ongoing debate about the best way of dealing with and reflecting these values that are, from the academic viewpoint, non-traditional. The debate has substantiated an emergent type of research that is specific to areas of design practice that is called âPractice-based Researchâ (PbR). PbR claims that design practice has an instrumental role in research in areas such as design and urban planning. This role is different from the role of experimentation in traditional empirical research, and different from the role of practice in professional design practice. This paper describes the development and delivery of a research methods training course in the department of spatial planning and design (Stedenbouw) at the Technical University Delft (TU Delft, Netherlands) that builds on research by the âNon-traditional Knowledge and Communicationâ project (NtKC) at the University of Hertfordshire (UK). The paper will analyse the way in which research and practice are problematized in the TU Delft course. We claim that the problem of PbR manifests the differences between the worldviews of academic research and professional practice, with their differing aims and values. As a result, training and expertise in the professional values of design practice is insufficient for academic research, leading to a need for specific training as a researcher that recognises these differences. This need has been accepted at an institutional level in many universities in Europe, and the TU Delft course represents one such training programme
Double-Mode Stellar Pulsations
The status of the hydrodynamical modelling of nonlinear multi-mode stellar
pulsations is discussed. The hydrodynamical modelling of steady double-mode
(DM) pulsations has been a long-standing quest that is finally being concluded.
Recent progress has been made thanks to the introduction of turbulent
convection in the numerical hydrodynamical codes which provide detailed results
for individual models. An overview of the modal selection problem in the HR
diagram can be obtained in the form of bifurcation diagrams with the help of
simple nonresonant amplitude equations that capture the DM phenomenon.Comment: 34 pages, to appear as a chapter in Nonlinear Stellar Pulsation in

High efficiency coherent optical memory with warm rubidium vapour
By harnessing aspects of quantum mechanics, communication and information
processing could be radically transformed. Promising forms of quantum
information technology include optical quantum cryptographic systems and
computing using photons for quantum logic operations. As with current
information processing systems, some form of memory will be required. Quantum
repeaters, which are required for long distance quantum key distribution,
require optical memory as do deterministic logic gates for optical quantum
computing. In this paper we present results from a coherent optical memory
based on warm rubidium vapour and show 87% efficient recall of light pulses,
the highest efficiency measured to date for any coherent optical memory. We
also show storage recall of up to 20 pulses from our system. These results show
that simple warm atomic vapour systems have clear potential as a platform for
quantum memory
An AC Stark Gradient Echo Memory in Cold Atoms
The burgeoning fields of quantum computing and quantum key distribution have
created a demand for a quantum memory. The gradient echo memory scheme is a
quantum memory candidate for light storage that can boast efficiencies
approaching unity, as well as the flexibility to work with either two or three
level atoms. The key to this scheme is the frequency gradient that is placed
across the memory. Currently the three level implementation uses a Zeeman
gradient and warm atoms. In this paper we model a new gradient creation
mechanism - the ac Stark effect - to provide an improvement in the flexibility
of gradient creation and field switching times. We propose this scheme in
concert with a move to cold atoms (~1 mK). These temperatures would increase
the storage times possible, and the small ensemble volumes would enable large
ac Stark shifts with reasonable laser power. We find that memory bandwidths on
the order of MHz can be produced with experimentally achievable laser powers
and trapping volumes, with high precision in gradient creation and switching
times on the order of nanoseconds possible. By looking at the different
decoherence mechanisms present in this system we determine that coherence times
on the order of 10s of milliseconds are possible, as are delay-bandwidth
products of approximately 50 and efficiencies over 90%
