title: How old are Australia's pictographs? A review of rock art dating

authors: David, Bruno O.

subjects: Archaeology of symbolism

abstract: Australia contains some of the world's richest and apparently longest traditions of rock pictographs. Dating this art, however, has been problematic, with few 'direct' and reliable dates of Pleistocene or early Holocene age having been obtained from visible, representational imagery. This paper critically reviews the evidence for the antiquity of pigment rock art in Australia by examining the various dating techniques employed. The accurate and reliable dating of rock art worldwide is crucial to understanding the evolution of modern human symbolism and whether cognitive modernism came about after, rather than with, the first signs of full biological modernism; understanding the pitfalls and devising proper methods are crucial prerequisites. Towards these ends, this paper reviews the results and techniques that have been employed to date the apparently earliest known pictographs in Australia.

title: Hands-on sharing: collaborative document manipulation on a tabletop display using bare hands

authors: Masoodian, Masood

subjects: computer science

abstract: Working on electronic shared documents on a tabletop display is an effective form of collaborative work, which is likely to become a common practice in the future. A limiting factor in using tabletop displays at present, however, is their lack of support for multiple direct input by several users, or their reliance on expensive devices for supporting multiple user inputs. This paper describes a simple set of hardware and software solutions for creating a back-projection tabletop display with bare hand input mechanism to allow users to gesture at and select positions in a shared collaborative document. The system provides for a mixture of private and public workspaces for each collaborator.

title: Restorying the individual: The cultural dimension of special education in three Te Arawa sites

authors: Macfarlane, Angus H

subjects: Māori special education

abstract: On the basis of observation of three Te Arawa educational sites, it is argued here that a central characteristic of successful programmes that attend to Māori students with special needs is cultural-centredness. Significant aspects of that culture-centredness are outlined here, aspects that, it is argued, are fundamental to the process of restorying that is, it is argued, critical to the success of many Māori students, particularly those with special needs.
