Australia's Antarctic agenda

Australia has had a long connection with, and significant national interests in, the Southern Ocean and Antarctica. The Australian Antarctic Territory comprises 42 per cent of Antarctica's landmass. Australia is not only a claimant state and original signatory to the Antarctic Treaty but has played a significant role in the development of what is termed the Antarctic Treaty System (ATS). This article aims to provide an overview of Australia's key policy interests and government policy goals towards Antarctica, including its commitment to the ATS. In examining key policy objectives we note that despite continuity and development of these objectives, significant changes and challenges have arisen in the period 1984–2006. It is these challenges that will help frame Australia's Antarctic agenda over the next 20 years and beyond.     

Memory,ghosts and the good life: Sati in Theravada cultural contexts

Mindfulness in its English rendering brings together a mix of historical influences, from Zen to Romanticism to yoga. Still, the most central concept from which it draws is sati, a Theravada Buddhist Pali term first translated as mindfulness over 100 years ago. This article reports on the findings of an ethnographic investigation of sati in the Theravada-majority countries of Thailand, Myanmar and Sri Lanka, where the concept is widely used for a range of religious, therapeutic and colloquial ends. Based on interviews and questionnaires involving over 600 monks, psychiatrists and lay Buddhist practitioners, the article explores aspects of sati that are not often recognized (or recognized as much) in Western, secular mindfulness contexts. These qualities include attention to memory in present-moment awareness, the potency of supernatural engagements and a social-ethical orientation towards living well. Highlighting these qualities allows for a greater appreciation of cultural diversity within contemporary global mindfulness practices and suggests possibilities for further developing the global therapeutic potential of mindfulness.     

Use of robust methods to determine quadratic surfaces: application to heritage

3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily).     

Finding Vikings in the Danelaw

Historical, artefactual and place‐name evidence indicates that Scandinavian migrants moved to eastern England in the ninth century AD, settling in the Danelaw. However, only a handful of characteristically Scandinavian burials have been found in the region. One, widely held, explanation is that most of these Scandinavian settlers quickly adopted local Christian burial customs, thus leaving Scandinavians indistinguishable from the Anglo‐Saxon population. We undertook osteological and isotopic analysis to investigate the presence of first‐generation Scandinavian migrants. Burials from Masham were typical of the later Anglo‐Saxon period and included men, women and children. The location and positioning of the four adult burials from Coppergate, however, are unusual for Anglo‐Scandinavian York. None of the skeletons revealed interpersonal violence. Isotopic evidence did not suggest a marine component in the diet of either group, but revealed migration on a regional, and possibly an international, scale. Combined strontium and oxygen isotope analysis should be used to investigate further both regional and Scandinavian migration in the later Anglo‐Saxon period.     

THE HALLATON INGOT: SILVER IN IRON AGE BRITAIN

This article is a case study of the detailed contextual and scientific analysis of a single object, moving beyond a conventional object biography to consider flows of materials and shifts in meaning and value. The object is a simple triangular silver ingot from the Late Iron Age shrine site at Hallaton, Leicestershire, UK. Scientific analysis is used to uncover the biography of the ingot, and the raw materials from which it was created. The results suggest that the metal which eventually formed the ingot circulated through both Iron Age and Roman social networks, being reworked and transformed several times before it was deposited. Silver emerges as a material which mediated between the Mediterranean world and Iron Age communities in Britain, allowing translation and transmutation between different systems of value in conquest‐period Britain.
