Defining synthesizer teaching

The synthesizer has come a long way since wendy Carlos' 'Switched On Bach'. Unfortunately many would not realise it. Synthesizers are in most of the popular and commercial music we hear, and their development has followed the rapid development of computing technology, allowing sugnificant perfromance leaps every five years. In the last 10 years or so, the physical interface of synthesizers has changed little even while the sound generating hardware has raced ahead. The stabilisation of gestural controller, particularly keyboard-based controllers, has enabled tje synthesizer to establish itself as an expressive instrument and one worthy of the hours of practice required on any instrument to reach a high level of proficiency. It is now time for the instrumental study of synthesizer to be taken seriously by music educators across Australia, and I hope, through this paper, to shed some light on the path forward.

Investigation of stereotactic radiotherapy dose using dosimetry film and Monte Carlo simulations

This study uses dosimetry film measurements and Monte Carlo simulations to investigate the accuracy of type-a (pencil-beam) dose calculations for predicting the radiation doses delivered during stereotactic radiotherapy treatments of the brain. It is shown that when evaluating doses in a water phantom, the type-a algorithm provides dose predictions which are accurate to within clinically relevant criteria, gamma(3%,3mm), but these predictions are nonetheless subtly different from the results of evaluating doses from the same fields using radiochromic film and Monte Carlo simulations. An analysis of a clinical meningioma treatment suggests that when predicting stereotactic radiotherapy doses to the brain, the inaccuracies of the type-a algorithm can be exacerbated by inadequate evaluation of the effects of nearby bone or air, resulting in dose differences of up to 10% for individual fields. The results of this study indicate the possible advantage of using Monte Carlo calculations, as well as measurements with high-spatial resolution media, to verify type-a predictions of dose delivered in cranial treatments.

Facilitating learning in a real time strategy computer game

The aim of this project was to implement a just-in-time hints help system into a real time strategy (RTS) computer game that would deliver information to the user at the time that it would be of the most benefit. The goal of this help system is to improve the user’s learning in terms of their rate of learning, retention and avoidance of stagnation. The first stage of this project was implementing a computer game to incorporate four different types of skill that the user must acquire, namely motor, perceptual, declarative knowledge and strategic. Subsequently, the just-in-time hints help system was incorporated into the game to assess the user’s knowledge and deliver hints accordingly. The final stage of the project was to test the effectiveness of this help system by conducting two phases of testing. The goal of this testing was to demonstrate an increase in the user’s assessment of the helpfulness of the system from phase one to phase two. The results of this testing showed that there was no significant difference in the user’s responses in the two phases. However, when the results were analysed with respect to several categories of hints that were identified, it became apparent that patterns in the data were beginning to emerge. The conclusions of the project were that further testing with a larger sample size would be required to provide more reliable results and that factors such as the user’s skill level and different types of goals should be taken into account.

Beyond the controller

Performance / presentation given at Freeplay 2010, Melbourne, Victoria as an invited guest for a session entitled "Beyond the controller" This performance intended to review the follies of tangible interface design for games since the appearance of games specific control peripherals in the 1980s. In this work I examine: Technology as prosthesis – designed artefacts that enable interaction in a virtual world; Technology as the dream of virtuality – mind-ware. IN each instance the controller DICTATES the form of interaction

Combating computer crime : an international perspective

Given the serious nature of computer crime, and its global nature and implications, it is clear that there is a crucial need for a common understanding of such criminal activity internationally in order to deal with it effectively. Research into the extent to which legislation, international initiatives, and policy and procedures to combat and investigate computer crime are consistent globally is therefore of enormous importance. The challenge is to study, analyse, and compare the policies and practices of combating computer crime under different jurisdictions in order to identify the extent to which they are consistent with each other and with international guidelines; and the extent of their successes and limitations. The purpose ultimately is to identify areas where improvements are needed and what those improvements should be. This thesis examines approaches used for combating computer crime, including money laundering, in Australia, the UAE, the UK and the USA, four countries which represent a spectrum of economic development and culture. It does so in the context of the guidelines of international organizations such as the Council of Europe (CoE) and the Financial Action Task Force (FATF). In the case of the UAE, we examine also the cultural influences which differentiate it from the other three countries and which has necessarily been a factor in shaping its approaches for countering money laundering in particular. The thesis concludes that because of the transnational nature of computer crime there is a need internationally for further harmonisation of approaches for combating computer crime. The specific contributions of the thesis are as follows: „h Developing a new unified comprehensive taxonomy of computer crime based upon the dual characteristics of the role of the computer and the contextual nature of the crime „h Revealing differences in computer crime legislation in Australia, the UAE, the UK and the USA, and how they correspond to the CoE Convention on Cybercrime and identifying a new framework to develop harmonised computer crime or cybercrime legislation globally „h Identifying some important issues that continue to create problems for law enforcement agencies such as insufficient resources, coping internationally with computer crime legislation that differs between countries, having comprehensive documented procedures and guidelines for combating computer crime, and reporting and recording of computer crime offences as distinct from other forms of crime „h Completing the most comprehensive study currently available regarding the extent of money laundered in four such developed or fast developing countries „h Identifying that the UK and the USA are the most advanced with regard to anti-money laundering and combating the financing of terrorism (AML/CFT) systems among the four countries based on compliance with the FATF recommendations. In addition, the thesis has identified that local factors have affected how the UAE has implemented its financial and AML/CFT systems and reveals that such local and cultural factors should be taken into account when implementing or evaluating any country¡¦s AML/CFT system.

Autopoiesis, language, literacy and the brain

When we attempt to speak about the relationship between language, literacy, and the brain, we find ourselves ill equipped to deal with these conceptually and qualitatively different phenomena. Immediately we must straddle different academic traditions that treat each of these as separate “things”. Broadly speaking, the study of language firstly belongs to the domain of biology, then to anthropology, sociology, and linguistics. At its most functional, a study of literacy education is a study of a particular technology, its diffusion techniques, and the abilities and motivations of people to adopt, or adapt themselves to, this technology. The brain is most commonly studied in the field of neurology, which is also a sub-discipline of biology, biochemistry, and medicine.
