title: Musical image compression

authors: Bainbridge, David

subjects: computer science

abstract: Optical music recognition aims to convert the vast repositories of sheet music in the world into an on-line digital format [Bai97]. In the near future it will be possible to assimilate music into digital libraries and users will be able to perform searches based on a sung melody in addition to typical text-based searching [MSW+96]. An important requirement for such a system is the ability to reproduce the original score as accurately as possible. Due to the huge amount of sheet music available, the efficient storage of musical images is an important topic of study. 
This paper investigates whether the “knowledge” extracted from the optical music recognition (OMR) process can be exploited to gain higher compression than the JBIG international standard for bi-level image compression. We present a hybrid approach where the primitive shapes of music extracted by the optical music recognition process-note heads, note stems, staff lines and so forth-are fed into a graphical symbol based compression scheme originally designed for images containing mainly printed text. Using this hybrid approach the average compression rate for a single page is improved by 3.5% over JBIG. When multiple pages with similar typography are processed in sequence, the file size is decreased by 4-8%.
Section 2 presents the relevant background to both optical music recognition and textual image compression. Section 3 describes the experiments performed on 66 test images, outlining the combinations of parameters that were examined to give the best results. The initial results and refinements are presented in Section 4, and we conclude in the last section by summarizing the findings of this work.

title: An account of possession in Larevet

authors: Barbour, Julie Renee

subjects: Malakula

abstract: This paper presents a first analysis of the Larevet language of central Malakula, Vanuatu, focusing on its possessive system. I locate the analysis within the literature on possession in the Oceanic language family broadly, seeking to understand how the synchronic system re- lates to both typological understandings within the family, and the possessive system recon- structed for Proto Oceanic. Drawing on a corpus of communicative and elicited language as evidence, I demonstrate that Larevet displays many features of a canonical Oceanic language, and that where changes have occurred, these align well with observations of possession in related languages of Malakula.

title: Searching for synergy: Māori/indigenous and scientific conservatory values - the affinity propositon

authors: Simon, Katerina Heremoana

subjects: Development studies

abstract: "Reconciling similarity/ affinity and difference/ distinction is one of the most important development issues of our contemporary period. Yet much effort aimed at gaining support for the plight of Māori/ indigenous peoples remains locked into the assertion of difference and distinction alone, those points of cultural affinity that could play an important role in processes of reconciliation and movement forward being largely ignored. What is proposed here is what is referred to as the ‘affinity proposition’, that is, it is argued that Māori/ indigenous development requires, for its further advancement, a focus not only on difference and divergence, but also on similarity and affinity. At the very heart of Māori/ indigenous development are issues relating to social justice, economic equity, freedom, ecological sustainability and cultural diversity, concepts which are equally highly valued in many sectors of mainstream (non-indigenous) society. Certainly, there are important differences in the ways in which these values are perceived and articulated in the context of different cultures, and these differences have recently been the focus of considerable attention and debate. However, there are also similarities which have received less attention in spite of the fact that they may hold the key to achieving a sufficient level of mutual understanding to underpin effective Māori/ indigenous development.

This paper explores the development of a synergistic process of reconciliation between Māori/ indigenous values and scientific conservatory values. It reports on the preliminary findings of a research project whose focus is a cross-cultural study of environmental governance and management regimes under the New Zealand Resource Management Act 1991. The central questions addressed here are: Can reconciliation be achieved through recognition of both affinity and difference? Could such reconciliation underpin effective Māori/ indigenous development? It is argued here that a process of synergy is already under way, a process that can best be understood in terms of a theoretical framework that encompasses both the concept of modernity and the sustainable development paradigm."
