Music needs no visa : insights from three South African voices on teaching African music in Melbourne, Australia

As Australia becomes increasingly multicultural, there are many that would argue that the teaching and learning of music at educational settings can be carried out in a number of ways where cultural context and authenticity is imperative. This paper discusses the main arguments of teaching and learning in music education and provides some theoretical perspectives of teaching African music as groundwork for the discussion and findings. This paper is part of a wider study called 'Smaller steps in longer journeys' and. provides insight into the teaching of South African music in Melbourne. Three South African voices (my own as tertiary music educator, an artist in schools and a primary music specialist) through reflection and interview data considers 'how' and 'why' African music is taught The discussion presents an openmindedness of music when it travels to a new country where the pedagogy is the process of production and exchange, a social-discursive practice whereby process and understanding is more important than just product. As music requires no visa it will continue to travel and be shared in different context where pedagogical practice considers teacher, learner and knowledge.

Thai hedging practices : post Asian financial crisis

This paper provides survey evidence captured from a sample of 113 respondents to a 2008 questionnaire that was sent to 344 listed non-financial companies in Thailand. The study examines how Thai companies manage their exchange rate exposure post Asian Financial Crisis.

Thailand is an interesting case study because it was a country at the core of the 1997 financial meltdown and was one of the first forced by the crisis to move from a fixed to a floating exchange rate regime. It is therefore constructive to examine how businesses in Thailand have coped with a shift from a fixed to floating exchange rate and to examine how they manage their exchange rate exposure post 1997.

Findings indicate that companies that use currency derivatives do so to reduce volatile cash flows are less risky and tend to be more profitable than companies that do not use currency derivatives. This is consistent with the theory that hedging increases the value of the firm.

The type of instruments that companies in Thailand use and how they are used is similar to what other studies find in other countries. Matching and the use of forward contracts are the most common ways that companies manage transaction exposure. The study also confirms that companies with higher levels of international business engagement are more likely to use currency derivatives.

What is unique in Thailand is that Thai businesses are less rigorous in their internal control of their currency hedging activities. It is therefore recommended that companies consider a documented hedging policy and that senior management actively monitor the policy and currency hedging activity.

Simulating crowd phenomena in African markets

Crowd simulation is an important feature in the computer graphics field. Typical implementations simulate battle scenes, emergency situations, safety issues or add content to virtual environments. The problem stated in this paper falls in the last category. We present a crowd simulation behavioural model which allows us to simulate identified phenomena in popular local African markets such as narrow street flows and crowd formation around street performances. We propose a three-tier architecture model enable to produce intentions, perform path planning and control movement. We demonstrate that this approach produces the desired behaviour associated with crowds in an African market, which includes navigation, flow formation and circle creation.

Modelling and rendering techniques for African hairstyles

We develop or enhance hair modelling and rendering techniques to produce three different forms of hair commonly found in African hairstyles. The forms of hair are natural curly hair, straightened hair, and braids or twists of hair.

We use an implicit model, implemented as a series of textured layers to represent curly hair. Straightened hair is represented explicitly, and modelled by defining and replicating a few control hairs. Braids and twists are implemented as textured generalized cylinders.

A synthesis of existing hair illumination models is used as a basis for an African hair illumination model. Parameter values to match African hair characteristics are discussed.

A number of complete African hairstyles are shown, demonstrating that the techniques can be used to model and render African hair successfully.

Duplicating road patterns in South African informal settlements using procedural techniques

The formation of informal settlements in and around urban complexes has largely been ignored in the context of procedural city modeling. However, many cities in South Africa and globally can attest to the presence of such settlements. This paper analyses the phenomenon of informal settlements from a procedural modeling perspective. Aerial photography from two South African urban complexes, namely Johannesburg and Cape Town is used as a basis for the extraction of various features that distinguish different types of settlements. In particular, the road patterns which have formed within such settlements are analysed, and various procedural techniques proposed (including Voronoi diagrams, subdivision and L-systems) to replicate the identified features. A qualitative assessment of the procedural techniques is provided, and the most suitable combination of techniques identified for unstructured and structured settlements. In particular it is found that a combination of Voronoi diagrams and subdivision provides the closest match to unstructured informal settlements. A combination of L-systems, Voronoi diagrams and subdivision is found to produce the closest pattern to a structured informal settlement.

Experiences in porting a virtual reality system to Java

Practical experience in porting a large virtual reality system from C/C++ to Java indicates that porting this type of real-time application is both feasible, and has several merits. The ability to transfer objects in space and time allows useful facilities such as distributed agent support and persistence to be added. Reflection and type comparisons allow flexible manipulations of objects of different types at run-time. Native calls and native code compilation reduce or remove the overhead of interpreting code.Problems encountered include difficulty in achieving cross-platform code portability, limitations of the networking libraries in Java, and clumsy coding practices forced by the language.

Experiencing indigenous East African dance songs : reflections from North West University (South Africa)

After democracy (1994) the doors of teaching and learning in music opened widely to include local indigenous music and culture in South Africa. Since 2005, African music has been a vibrant aspect of the music curriculum within the School of Music, North West University, South Africa. Globally tertiary music educators are challenged to include informal pedagogy of indigenous musics within the formal context of university courses. University music courses in South Africa are still predisposed towards ‘western’ music pedagogies. In October 2012, the School of Music invited a visiting expert in African music and dance to offer onsite teaching and learning of Ugandan dance songs to tertiary students. The initiative to include Ugandan music as part of the teaching and learning workshops on African music at the School of Music was funded by the South African Music Rights Organization. The School of Music has an ongoing policy to invite and include culture bearers to share their skills and expertise with students and academics. Such sharing provides culture bearers the opportunity to transmit much needed skills, which are not often offered by academics. UNESCO (2012) identifies scarce knowledge and skills as intangible heritage.
