title: Review of Anne Freadman. The machinery of talk: Charles Peirce and the sign hypothesis

authors: Legg, Catherine

subjects: philosophy

abstract: Book Review: This book, officially a contribution to the subject area of Charles Peirce’s semiotics, deserves a wider readership, including philosophers. Its subject matter is what might be termed the great question of how signification is brought about (what Peirce called the ‘riddle of the Sphinx’, who in Emerson’s poem famously asked, ‘Who taught thee me to name?’), and also Peirce’s answer to the question (what Peirce himself called his ‘guess at the riddle’, and Freadman calls his ‘sign hypothesis’).

title: Assay of the antioxidant capacity of foods using an iron(II)-catalysed lipid peroxidation model for greater nutritional relevance

authors: Brangoulo, Helene L.

subjects: antioxidants

abstract: The formation of free radicals by the iron-catalysed Fenton reaction is a major cause of oxidative damage in the body. Here a common assay of antioxidant capacity, inhibition of the β-carotene-linoleic acid model of lipid peroxidation, has been modified by the addition of ferrous iron (final concentration 36 μmol/l), which makes the rate of oxidation of the lipids occur twenty-five times faster. Such an assay can simulate the oxidative damage to membrane lipids and low density lipoproteins occurring in the body in the presence of free iron. It thus may be nutritionally more relevant than traditional chemical assays of antioxidant capacity, as it measures pre-emptive antioxidant activity, i.e. activity which prevents free radicals being formed in the first place. Pre-empting their formation is likely to be more protective than scavenging of free radicals. The relative antioxidant activity of some food products found using this new assay was very different from that found using a radical-scavenging assay. Vitamin C, at 280 mg/l, was found to be sixty times better than blackcurrant puree in scavenging free radicals, but only one eighth as good as the blackcurrant puree in preventing iron-catalysed lipid peroxidation.

title: A Portfolio of Compositions

authors: Dobson, Elizabeth Jane

subjects: music

abstract: The pieces in this portfolio cover a wide range of methods and styles - from work for a single vocalising percussionist, to singing bowl and electronics and a work for full orchestra. The aim of this portfolio is to demonstrate my technical and musical proficiency as well as to give an overview of my personal composing philosophy and style.
The portfolio opens with a work for orchestra, A Study in Scarlet. It differs from my previous orchestral works and is based on a musical code of Sir Arthur Conan Doyle's book, titled A Study in Scarlet. This was read in the 2009 Todd/ NSZO Young Composer Readings. The second work is .manatu.. It features tinkly piano, wind chimes and ethnic instrumentalists in a chamber ensemble to create a musical sound world. This was written for and premiered at Bang on a Can's summer music festival in Massachusetts 2009. The piano work .ātanga. is an adaptation of .manatu. for solo pianist and was written for the Dame Malvina Major Foundations Showcase Concert in New Plymouth. This adaptation proved to be a worthwhile exercise in efficient use of music material. Wrong Number is a Janet Frame poem set for soprano and real-time effect processing of audio. Confessions - Part I and II, for solo violin and string orchestra is based on the Fibonacci series and explores my love for string sonorities. Sand Song was written for a friend who asked me to set a poem she wrote. Here I demonstrate my love for setting text and voice to say something beautiful and precise. This song now stands as a eulogy for her Father. Parihaka, for vocalising percussionist, is a setting of Apirana Taylor's poem Parihaka and was written for Australian performer Louise Devenish. I explore further in the realm of live acoustic and electroacoustic music with Orison a piece I wrote for myself to perform live with singing bowl and Ableton Live. Finally The Headlines Today for five improvising musicians explores the music of shouting and the vernacular of place.
