title: English in a surveillance regime: Tightening the noose in New Zealand

authors: Locke, Terry

subjects: education

abstract: It is a contemporary commonplace that we live in a ‘text-saturated’ environment – a semiosphere that complements those biologically rooted spheres our bodies inhabit. The neon cityscape of Tokyo in the movie, Lost in Translation, might be thought of as a metaphor for this semiosphere, this universe of signs which regularly coalesce in clusters of meaning that some people call discourses. To extend the metaphor, you could say that we both inhale and exhale discourse, and that discourse is changed in the ‘breathing’ process. The individual is both agent and subscriber to whatever ‘truths’ are generated in his/her ongoing engagement with the semiosphere.

title: Visco–resistive dissipation in transient reconnection driven by the Orszag–Tang vortex

authors: Armstrong, Craig Keith

subjects: Flares

abstract: Viscous effects are expected to significantly contribute to reconnective energy release mechanisms in solar flares. While simple scaling arguments based on head-on reconnection suggest that viscous dissipation may dominate resistive dissipation, it is not clear whether these findings can be applied in more general merging situations. Here we perform side-by-side planar reconnection simulations driven by the Orszag-Tang vortex, for both classical and Braginskii forms of the viscosity. This formulation has the advantage of providing an autonomous MHD system that develops strong current layers, sustained by large-scale vortical shearing flows. The dissipation rates are shown to follow analytically based scaling laws, which suggest that viscous losses generated from large-scale non-uniform velocity fields are likely to dominate resistive losses in current-sheet reconnection solutions.

title: Technology, culture and location in a recent New Zealand sonic art project

authors: Whalley, Ian

subjects: music

abstract: The HIEMPA (Hybrid Instruments from Electroacoustic Manipulation And Models of Pütorino and Aquascape) project combined a team of people with technical, artistic, environmental and cultural expertise toward the artistic outcome of extending the New Zealand sonic art tradition. The project involved collecting audio samples from the aquascape of the Ruakuri Caves and Nature Reserve in Waitomo, South Waikato, New Zealand; and samples of a variety of Pütorino – a New Zealand Mäori wind instrument. Following a machine learning analysis of this audio material and an analysis of the performance material, hybrid digital instruments were built and mapped to suitable hardware triggers. The new instruments are playable in real-time, along with the electroacoustic manipulation of Pütorino performances. The project takes into account the environmental and cultural significance of the source material, with the results to be released as a set of compositions. This paper discusses the research process.
