This article sets out to present a new imagery for capturing the power and potential of Olympism in attempting to educate the next generation of sport consumers and decision makers. It is hoped that the new imagery can make a contribution on how to moderate and regulate the rampant commodification of sport. This new imagery begins with the need for physical educators to open their minds and instigate a critical orientation to thinking about sport and Olympic matters. It is argued that doing this might help in the creation of new possibilities and visions for Olympism and sport and allow us to confront some of the disagreeable contemporary concerns in sport that scholars have identified. The new imagery for Olympism is based on the development of a critical pedagogy that draws on the works of Apple, Freire and Kincheloe, and is re-contextualised for school physical education and sports programmes. It is concluded that decisions, behaviours and actions that are made at present actually propagate many of the policies that will be made tomorrow. It is argued that a critical pedagogy for Olympism is needed to address the many current disagreeable aspects of sport.

First Time

In this article, Kuntz argues for new orientations to inquiry that enact immanently entangled processes of mapping, refusing, and making—radical practices with implications for resisting the fascisms of our present time. As an extended example, Kuntz explicates one such critical orientation, parrhesia, as an inquiry orientation that manifests through an ethical determination to challenge the exploitative relations of our present. Through this example, Kuntz challenges inquirers to work with, but not become of, our contemporary moment. Any “new” inquiry practice pushes convention to its limit, reconfiguring it in such a way that convention is recognized as such for the first time through its very dissolution. Thus, there remains an important element of critical engagement within the “new”; one that manifests as an ethical challenge from within.

Design And Construction

We discuss the design and construction of a Faraday isolator for diode laser spectroscopy using commercially available components. The design involves modelling the magnetic field of an assembly of cylindrical magnets and verifying the predictions using a sensor. We obtain an isolation ratio for optical feedback of ∼35 dB at a wavelength of 780 nm. The cost is approximately one-fourth the cost of an equivalent commercially available device. We expect that the design can be widely used in experiments in laser spectroscopy and in advanced undergraduate laboratory experiments.PACS Nos.: 01.50.Pa, 32.80.Pj, 39.25.+k, 42.62.Fi

Purpose The purpose of this paper is to reflect a critical perspective drawing from phenomenology, especially informed by a reading of Heidegger, to enhance and extend appreciation of the need to question accounting’s meaning or delineation and how research might be undertaken into the accounting phenomenon and related areas. Design/methodology/approach To illustrate and clarify argumentation in terms of accounting mobilization and the domain of accounting research, the mainstream and strongly positivistic accounting perspective adopted in the USA is critically assessed. At the same time, the authors elaborate how much of interpretive research (including much of that labeled critical) is also lacking in terms of the perspective articulated here. Findings The paper stresses the case for questioning the taken-for-granted and conventional. It promotes reflexivity, cautious pragmatism, attentiveness to the value of the existing, responsibility to difference and otherness and openness to new possibilities as part of a deeper critical orientation. Originality/value The paper draws from phenomenology, especially in Heideggerian terms to open-up new conversational domain to debate accounting.
