title: Composition Portfolio

authors: Ulenberg, Phillippa

subjects: composition portfolio

abstract: The music written for this portfolio offers creative answers to some of the challenges facing contemporary New Zealand composition, including multiculturalism.This has involved in-depth research using a variety of methods. Engagement was undertaken with linguists and musicians from Malaysia and Korea, who not only assisted with texts, but also spoke knowledgeably about their cultural traditions and past and present musical genres. The inclusion of Chinese gu-zheng in several of the works was made possible with the assistance given by Chen Xi Yao, an excellent performer who comes from a long lineage of musicians. Attending concerts given by performers of the instruments that have been used in the portfolio was essential to understanding the sounds and uses of the instruments. In addition, on-line sources include many examples of the sounds. Attendance at workshops on Māori taonga pūoro also brought the additional honour, benefits and experience of making and playing the instruments, and the opportunities to meet and work with leading makers and performers of these musical treasures. Sources of Western classical music that have been particularly influential during the writing of the portfolio are orchestral works by Igor Stravinsky, Samuel Barber and Param Vir, and the song cycles of Alban Berg and Benjamin Britten. Luciano Berio’s virtuosic piece for solo bassoon was also instructive. Experiences of composition, reflection and scholarly research underpin the portfolio and have have informed the composition of each work.

title: Anō, ko te Riu ō Tāne Mahuta Possibilities and Challenges in a Ngāti Rangiwewehi Curriculum

authors: Mahuika, Rangimarie

subjects: Curriculum

abstract: This thesis considers how a curriculum might form a useful tool in meeting the needs and aspirations of Ngāti Rangiwewehi, a small, but dynamic tribe, who occupy specific territory from the north western shores of Lake Rotorua into the eastern Bay of Plenty of the North Island of New Zealand. In contemplating the potential benefits of a curriculum, this study begins by examining the epistemological frames of reference crucial to understanding how the tribe views the world around them, and their positioning within it. The thesis goes on to explore the pedagogical approaches specific to the iwi, and concludes by assessing the extent to which a curriculum is a viable means of maintaining and empowering Rangiwewehi mātauranga, and their underlying ambitions, and goals. Whether ‘curriculum’ is an appropriate framework to describe the way Ngāti Rangiwewehi view our educational processes, is an issue addressed in this study. To this extent, Rangiwewehi perspectives are intentionally privileged allowing appropriate representation of our understandings and aspirations. Eighteen people were interviewed as part of this study, yet many other voices included here were recorded during a tribal wānanga held in late 2010. Their accounts provide the core ideas and positions at work in this thesis, and are invaluable for the depth and texture they offer. An emphasis on the qualitative data collected here is important in allowing their words to take centre stage. In conveying their views and stories, three major themes emerged: these were people, place, and survival. Woven through the body of the thesis, these themes work to illustrate the key designs and patterns that were seen as fundamental to a Rangiwewehi way of viewing the world. Place and people, for instance, were affirmed as crucial to both the pedagogical and epistemological beliefs and practices maintained across generations. Similarly, the theme of survival was deemed a significant thread in comprehending the struggle and self-determination inherent in the tribe’s sense of identity and knowing. These themes reflect convictions shared across the iwi, highlighting the importance of understanding Ngāti Rangiwewehi by first listening to what they have to say about themselves and their curriculum.

title: Review: Biomolecular stability and life at high temperatures

authors: Daniel, Roy M.

subjects: archaea

abstract: It is not clear what the upper temperature limit forlife is, or what specific factors will set this limit, but it is generally assumed that the limit will be dictated by molecular instability. In this review, we examine the thermal stability of two key groups of biological molecules: the intracellular small molecules/metabolites and the major classes of macromolecules. Certain small molecules/metabolites are unstable in vitro at the growth temperatures of the hyperthermophiles in which they are found. This instability appears to be dealt with in vivo by a range of mechanisms including rapid turnover, metabolic channelling and local stabilisation. Evidence to date suggests that proteins have the potential to be stable at substantially higher temperatures than those known to support life, but evidence concerning degradative reactions above 100p°C is slight. DNA duplex stability is apparently achieved at high temperature by elevated salt concentrations, polyamines, cationic proteins, and supercoiling rather than manipulation of C-G ratios. RNA stability seems dependent upon covalent modification, although secondary structure is probably also critical. The diether-linked lipids, which make up the monolayer membrane of most organisms growing above 85p°C are chemically very stable and seem potentially capable of maintaining membrane integrity at much higher temperatures. However, the in vivo implications of the in vitro instability of biomolecules are difficult to assess, and in vivo data are rare.
