title: A reduced magnetohydrodynamic model of coronal heating in open magnetic regions driven by reflected low-frequency waves

authors: Oughton, Sean

subjects: MHD

abstract: A reduced magnetohydrodynamic (RMHD) description is employed to examine a suggestion made by W. H. Matthaeus and colleagues in 1999 that coronal heating might be sustained by a cascade of low-frequency MHD turbulence. Here RMHD simulations show that the low-frequency cascade to high transverse wavenumbers can be driven by an externally maintained flux of low-frequency propagating Alfvén waves, in combination with reflection caused by an inhomogeneous background medium. The simulations show that the suggestions made previously on the basis of a phenomenology are indeed realizable. In addition, the effect is seen to sensitively depend on the presence of reflection, as the background turbulence level needed to maintain the cascade can be sustained only when reflection is imposed. The steady level of turbulence is insensitive to the initial seed turbulence level (provided it is nonzero). Consequences of this model for realistic models of coronal heating in open field-line regions are discussed.

title: The Taxonomy of Demospongiae (Porifera) from the Bay of Plenty, New Zealand - Connecting Linnaean and Phylogenetic Classification

authors: Mc Cormack, Samuel Patrick

abstract: The ability to accurately identify species is prerequisite for assessing levels of biological diversity and a fundamental requirement for ecological research. In recent times, there has been a shortfall in biologists who practice traditional alpha taxonomy, leading to difficulties in assessment of biodiversity in some taxonomic groups. The use of a molecular DNA barcoding approach has been suggested as a tool that can be used to complement and accelerate traditional alpha taxonomy, without supplanting or invalidating existing taxonomic practices.
Two different techniques were used to identify organisms, molecular and alpha taxonomy. This thesis addressees several questions relating to sponge systematics. Research was focused on three areas; (1) record sponge biodiversity from the Bay of Plenty region, (2) undertake a systematic revision of the fauna correlating ‘historical’ taxonomy with a modern phylogenetic assessment (3) determine whether identifications based on genetic barcoding are congruent with those produced via traditional morphological methods (alpha taxonomy), and to assess the use of molecular techniques for Demospongiae species identifications.
This was the first focused research on sponge diversity in the Bay of Plenty region. Fifty five species are described in this research. Of these, there are up to three new families, three new genera and thirty four species which are un-described and deemed new to science. However, a more conservative estimate with grouped specimens suggests that there is a minimum of at least one new family, one new genus, and eighteen new species that are un-described and deemed new to science. In summary, we conclude that for New Zealand Demospongiae, sequence variation present in the barcoding region of the COI gene is sufficient to allow for the identification individuals to their nominate species. The use of mtDNA barcoding can without doubt complement classical morphological taxonomy and accelerate the identification process and may in fact revive an interest classical morphological taxonomy.

title: Performing Femininity. Carmen - Good Ship Lollipop: A solo performance

authors: Fraser, Elroy

subjects: Performance

abstract: In the tradition of queer fringe theatre, Carmen - Good Ship Lollipop: a solo performance was written by a queer playwright, with a queer message for a queer audience.  The play was devised by drawing on Queer Theatre practice and methodology.
The following thesis details the process I undertook to create Carmen - Good Ship Lollipop: a solo performance. The story was created using biographical content already in the public arena. The play is about the public life of the late Carmen Rupe, New Zealand’s most famous transsexual. 
A historical perspective of men performing as women, or more fittingly, femininity performed by those other than female is presented by drawing on literature of this genre. The place of the solo performer and the combined roles of the actor, director, and producer are explored. Definitions of queer theatre and female impersonation are presented and issues of imitation, innovation and authenticity discussed.
The first methodology section details the choice of the particular playtext, the scriptwriting process, and dramaturgical analysis of Carmen – Good Ship Lollipop: a solo performance 
The second methodology section details the ‘script to stage’ production process. The development of the rehearsal script and the decision to limit the rehearsal period to one week is discussed. The plays evolution in terms of style and structure is presented.
The conclusion analyses the final product: to what extent Carmen - Good Ship Lollipop: a solo performance is faithful the Queer Theatre genre, successful as a performance piece, and reactive enough to be relevant. What further development could be applied in order to perform a future season.
