title: Acoustic Vector Network Analyser

authors: Pennington, Kyle

subjects: Acoustic

abstract: This research aims at increasing the accuracy and precision of characterising acoustic materials by adapting well-known techniques developed for the radio-frequency domain to the acoustic domain. 
Two novel methods are developed with different approaches for determining the reflectivity of materials: computationally and physically. 
The first method is a advancement of the current “industry standard”, the impedance tube, by using additional microphones and error correcting methods. A vector network analyser (VNA) is used as the data acquisition component with the aim of developing a module to allow the device to measure in the acoustic domain. The multi-microphone method employs the use of a mathematical model of the acoustics with the impedance tube to computationally solve for the unknown acoustic properties. The method is found to contain multiple sources of error at each stage of the process which makes reliable calibration and measurement difficult. The advantage of using a VNA is lost due to the inclusion of non-systematic error. 
The second method uses wave superposition to form directional couplers to determine the reflectivity. This method allows for a more robust calibration routine as the error is systematic and can be corrected using intelligent procedures and measurement standards. The measurement accuracy was found to be ± 1.5 dB over a frequency range from 800 to 2200 Hz . The device is used to characterise the acoustic properties of pasture in order to aid the development of pasture meters. Pasture was found to reflect a relatively small amount and absorb the majority of the incident acoustic energy.

title: Sport and education: Sport in secondary schools for all or for some?

authors: Grant, Bevan C.

subjects: sports

abstract: The place of sport in schools has always been controversial and struggled to gain legitimacy and acceptance as a part of the formal curriculum. While some commentators argue sport has no place in the curriculum, others claim it is too important to be left to chance and, like other aspects of education, it can and should be pursued for its own intrinsic value. For example, Siedentop (1982, p. 2) stated, 'if sport is equal to other ludic [movement] forms (art, drama, music and dance) both for the individual and the culture; and if more appropriate participation in sport represents a positive step in cultural evolution then sport in education is justified'. From another but still supportive perspective, Arnold (1997, p. I) claimed, 'sport is a trans-cultural valued practice ... and despite its corruption from time to time it is inherently concerned with concepts, ethical principles and moral values which are universally applicable and justified as a form of education'

title: Romeo and Tusi: An eclectically musical Samoan/Māori Romeo and Juliet from Aotearoa/New Zealand

authors: Houlahan, Mark

subjects: Romeo and Tusi

abstract: Is there a distinctive New Zealand Shakespeare? What ‘new’ approaches to Shakespeare have originated from New Zealand? This article explores the issue by contextualising a version of Romeo and Juliet staged successfully throughout New Zealand in the late 1990s. The production is set against the background of the history of Shakespeare in New Zealand, which goes back to the arrival of Captain Cook on the Endeavour in 1769.

Pacific Underground's Romeo and Tusi sought a looser and more populist kind of Shakespeare performance. They used the conceit of rehearsing the play at high school, where a Māori Romeo and a Samoan Juliet cross community boundaries. Drawing on several music genres, and performing outdoors, they generated a Shakespeare that audiences from a diverse range of ethnic and cultural communities could enjoy.
