title: Anisotropic viscous dissipation in transient reconnecting plasmas

authors: Craig, Ian J.D.

subjects: magnetohydrodynamics (MHD)

abstract: Aims. We examine the global energy losses associated with reconnecting coronal plasmas.
Methods. Using planar magnetic reconnection simulations we compute resistive and bulk viscous losses in transient coronal plasmas. Resistive scalings are computed for the case of incompressible reconnection powered by large scale vortical flows. These results are contrasted with an example of magnetic merging driven by the coalescence instability.
Results. We demonstrate that the large scale advective flows, required to sustain resistive current sheets, may be associated with viscous losses approaching flare-like rates of 10²⁹ erg s⁻¹ . More generally, bulk viscous dissipation appears likely to dominate resistive dissipation for a wide variety of magnetic merging models. We emphasize that these results have potentially important implications for understanding the flare energy budget.

title: Book Review Essay: Reimagining the subject of feminism: Six women artists

authors: Middleton, Sue

abstract: Maria Tamboukou is a Reader in Sociology and Co-Director of the Centre of Narrative Research at the University of East London,  UK. A trans-disciplinary feminist writer, Tamboukou is known for imaginative conceptual assemblages in the study of narrative texts. Influenced by Hannah Arendt and Adriana Cavarero, she argues: “narratives foreground the question of Who one is, as differentiated from the Western (male) philosophical tradition that has revolved around the question of What one is” (Tamboukou, 2010a: 13). “Who” one is, however, is never fixed, never stable, always in process – in Deleuzian terms, nomadic. Citing Rosi Braidotti, (Tamboukou 2010a: 84) defines nomadic subjects as always in transition, characterised not by homelessness but by “their ability to create their homes everywhere” in the process of becoming.

title: Working at the interface: Indigenous students’ experience of undertaking doctoral studies in Aotearoa New Zealand

authors: McKinley, Elizabeth

subjects: Māori

abstract: Māori (indigenous)¹ doctoral students in Aotearoa New Zealand face challenges not usually experienced by other doctoral candidates. We draw on data from in-depth interviews with 38 Māori doctoral candidates and argue that because of the tensions between academic disciplinary knowledge frameworks and knowledge drawn from te ao Māori (the Māori world) indigenous students have additional cultural, academic, and personal demands placed on them while aiming to produce research theses that meet conventional standards of academic scholarship. Complex methodological and ethical issues also emerge in undertaking doctoral research projects situated at the interface of academy and indigenous communities. Moreover, Māori students experience various degrees of tension between their sometimes strong cultural identities and their emerging and, therefore, less certain identities as researchers and scholars.
