Automatic grain texture analysis using integral transforms

Tonewood for musical instruments is quarter-sawn and frequently quality-graded based on visual appearance, mechanical and acoustic properties. The assessment uses simple human (subjective) observation, and two ‘‘experts’’ can rate the same sample differently. This paper describes the application of integral transforms (Fourier and Radon) for automatic (objective) assessment of the visual appearance of 10 Sitka spruce (Picea sitchensis) sample images. This work considers surface classification on the basis of grain orientation, count, spacing, and evenness or uniformity.

Collecting diversity: the changing relationships between museums and culturally diverse communities

 Much of the focus of scholarship around cultural diversity and museums has taken the advent of multiculturalism in 1973 as a starting point. However, public museums also collected and exhibited items relating to culturally diverse communities from the time they were set up from the 1850s onwards, and my research seeks to produce a pre-history of contact between museums, governments and culturally diverse communities and individuals. By using objects and collections life histories from the time they enter the museum for collection and/ or exhibition purposes, I will analyse the way that these relationships have changed over time. One case study is of the gamelan Digul, parts of which are currently on display in the Australian Journeys gallery at the National Museum of Australia. The gamelan Digul first entered the collection of the National Museum of Victoria in 1946 when the museum accepted the donation of these musical instruments from Indonesians who were being deported after World War II. The gamelan remained in this collection until 1976 when it was deacessioned to Monash University who restored and exhibited it in 1999. The National Museum of Australia borrowed some instruments from the gamelan in 2009. Some of the questions I will explore are: What were the motivations behind the former political prisoners/ Indonesian citizens in donating the gamelan Digul to the National Museum of Victoria and why did the museum accept it? Why was the gamelan Digul deaccessioned to Monash University?  How does the display of these instruments at the NMA represent the historical Indonesian communities in Australia which was deported? 

Children’s preferences for group musical activities in child care centres : a cross-cultural study

This paper reports on a cross-cultural research study of children’s preferences for group musical activities in child care centres. A total of 228 young children aged 4–5 years in seven child care centres in Hong Kong and in the Adelaide City of South Australia participated in the study. Both qualitative and quantitative data were collected via a mixed method approach. Result showed that dancing/moving was children’s most preferred musical activity in centres. Significant differences were found between children’s cultural contexts and their preferences for three activities: (1) Singing; (2) Listening; and (3) Playing instruments. Qualitative data further revealed the social phenomena of these two cultural contexts which influenced children’s preferences. Implications for the curriculum planning of early childhood music education arising from these findings are discussed.
