Diffraction and response-able reading of texts: the relational ontologies of Barad and Deleuze

In this paper, we use a diffractive reading developed by feminist philosopher and quantum physicist Karen Barad, as part of a response-able methodology, in order to consider the claim made by Serge Hein in his paper ‘The New Materialism in Qualitative Inquiry: How Compatible Are the Philosophies of Barad and Deleuze?’ (2016) that the philosophies of Barad and Deleuze and Guattari are incommensurable. Our point of departure is from a stance which is quite different from that of Hein’s – we propose that it is indeed productive to put the work of Barad into conversation with that of Deleuze. As an alternative to critique used by Hein to engage with the work of Barad and Deleuze, we consider how a response-able and diffractive reading of notions of critique could provide a more affirmative and productive way of reading academic texts, including those by Barad and Deleuze.     

Engineering problem-solving knowledge: the impact of context

Employer complaints of engineering graduate inability to ‘apply knowledge’ suggests a need to interrogate the complex theory-practice relationship in twenty-first century real world contexts. Focussing specifically on the application of mathematics, physics and logic-based disciplinary knowledge, the research examines engineering problem-solving processes as enacted by recent graduates in a range of industrial settings. Theoretically situated in the sociology of education, the Bernsteinian concept of knowledge structures and Legitimation Code Theory epistemic relations are utilised to surface the disciplinary basis of problem solving in different sociotechnical contexts. It is argued that the relationship between the ‘what’ and the ‘how’ of the problem gives rise to significantly different practice ‘codes’ between which successful engineering problem-solvers are required to shift. This paper presents two contrasting case studies which demonstrate the impact of the environment on code-shifting practices. Findings suggest that engineering curricula need to facilitate a more conceptual grasp of contextual complexities.     

Young students’ aesthetic experiences and meaning-making processes in an outdoor environmental school practice

This study uses John Dewey’s theoretical concept of ‘aesthetic experience’ in empirically exploring expressions of cognition and emotion in students’ meaning-making processes. A case study was conducted in one class of Grade 6 students during a single school semester. This article reports results from five outdoor days. The empirical material consists of observations, field notes, logbook entries, interviews and students’ written reflections. The students’ meaning-making processes were analyzed through the Deweyan theory of an initial phase involving anticipation, an activity phase with courses of actions and a concluding phase with reflections that serve as fulfillments. Expressions of aesthetic experience were identified in four important components of the students’ meaning-making processes: prior personal experiences; responses to environments and artifacts; social interaction; and situations allowing for responsibility, trust and independence. A more in-depth process-oriented analysis revealed that aesthetic experiences are vital in continuous meaning-making processes.

ATP and phosphocreatine utilization in single human muscle fibres during the development of maximal power output at elevated muscle temperatures

In this study, we examined the effect of muscle temperature (Tm) on adenosine triphosphate (ATP) and phosphocreatine utilization in single muscle fibres during the development of maximal power output in humans. Six male participants performed a 6-s maximal sprint on a friction-braked cycle ergometer under both normal (Tm = 34.3 degrees C, s = 0.6) and elevated (T(m) = 37.3 degrees C, s = 0.2) muscle temperature conditions. During the elevated condition, muscle temperature of the legs was raised, passively, by hot water immersion followed by wrapping in electrically heated blankets. Muscle biopsies were taken from the vastus lateralis before and immediately after exercise. Freeze-dried single fibres were dissected, characterized according to myosin heavy chain composition, and analysed for ATP and phosphocreatine content. Single fibres were classified as: type I, IIA, IIAX25 (1 - 25% IIX isoform), IIAX50 (26 - 50% IIX), IIAX75 (51 - 75% IIX), or IIAX100 (76 - 100% IIX). Maximal power output and pedal rate were both greater (P < 0.05) during the elevated condition by 258 W (s = 110) and 22 rev . min(-1) (s = 6), respectively. In both conditions, phosphocreatine content decreased significantly in all fibre types, with a greater decrease during the elevated condition in type IIA fibres (P < 0.01). Adenosine triphosphate content was also reduced to a greater (P < 0.01) extent in type IIA fibres during the elevated condition. The results of the present study indicate that after passive elevation of muscle temperature, there was a greater decrease in ATP and phosphocreatine content in type IIA fibres than in the normal trial, which contributed to the higher maximal power output.     

Learning to collaborate in a peer-tutoring situation: Who learns? What is learned?

The issue of “collaborating to learn” is tackled by analysing a peer-tutoring situation aimed at providing help to students with learning difficulties. The corpus consists of a six-lesson cycle between a 15 year-old student and her 14 year-old tutee who has difficulties with German. The analysis shows that the tutor and the tutee interactively construct the asymmetry and complementarity of their roles. As a consequence, what seemed at first sight to be the tutor’s discursive and guidance abilities appears, upon closer examination, to be the result of the students’ interactional work. In this particular case, the mode of collaboration which is achieved results in the tutor taking charge of the major part of the cognitive work.     

Abortion and Infanticide

Abstract

This issue introduces an occasional series where readers are invited to argue points of view, express opinions, raise issues they deem important ‐ or indeed disagree with an earlier point of view. Controversy need not be avoided! Contributions to the series, which should normally fall between 400 and 2000 words are now being sought.

The first contribution is concerned with abortion and infanticide and the moral problems thrown up by following certain lines of philosophical enquiry to their logical conclusion. Karin Bernath introduces the topic, pointing out that this is a topic intensely debated in the German‐speaking world, and Hans Furrer develops some of the philosophical implications in his paper. It is perhaps well to be reminded of these matters as the shades of World War II and the ideologies that underpinned it are once more in our minds.
