A HYBRID APPROACH TO CREATE AN ARCHAEOLOGICAL VISUALIZATION SYSTEM FOR A PALAEOLITHIC CAVE

This paper presents a visualization system based on metric data to manage and disseminate archaeological information on the Internet. We describe the integration of two different types of sensors: laser scanning and close‐range photogrammetry. How we created an automatic and hierarchical approach based on processing and matching the images coming from a digital camera and a terrestrial laser scanner is also shown. This development has created a visualization system combining spherical photographs and georeferences for graphical and numerical data acquired by the sensors. The case study where we have applied this method is the Palaeolithic rock art of the Llonín Cave (Asturias, Spain), which has been declared a World Heritage Site by UNESCO and has restricted public access. Our results demonstrate that this tool integrates data, metadata, services and information, which simplifies the location, identification, selection and management of archaeological information.     

A PROVENANCE STUDY OF FRENCH LIMESTONE BASED ON VARIABLE SELECTION FROM COMPOSITIONAL PROFILES

The present study shows how multivariate analysis and variable selection techniques can be used in archaeological provenances studies to improve classification performances. Neutron activation analysis (NAA), in combination with stepwise linear discrimination analysis (SLDA) (capable of simultaneously performing variable selection and classification), was applied to differentiate among limestone samples from different quarries across the north of France based on their compositional fingerprint. A hierarchical classification approach was followed, aimed at progressively assigning limestone samples to more specific sources of origin, from the broadest classification units (French regions) to the narrowest ones (individual quarries). The application of the stepwise variable selection procedure to extract the most discriminating compositional variables prior to each classification development allowed us to obtain a perfect separation between the limestone categories considered at every classification stage (all samples were correctly classified and predicted in all cases). The high‐quality results obtained were even more remarkable considering the relatively small number of significant variables selected in each case using the SLDA method. An illustrative example was provided in order to demonstrate that the classification strategy proposed can actually allocate an unknown sculpture to a particular quarry of origin.     

Was Iraq an unjust war? A debate on the Iraq war and reflections on Libya*

This article is based on a debate held on 22 March 2011 at Chatham House on ‘Was Iraq an unjust war?’ David Fisher argues that the war fully failed to meet any of the just war criteria. The war was undertaken to disarm Iraq of its WMD but the evidence that it had such weapons was inadequate. There were concerns about the justice of the cause, reinforced by doubts that those initiating military action avowedly on behalf of the UN had the requisite competent authority to do so, given the absence of any international consensus in favour of military action. The doubts were further reinforced by concern that action was being undertaken too soon and not as a last resort. Crucially, no adequate assessment was undertaken before military action was authorized to seek to ensure that the harm likely to result would not outweigh the good achieved. The individual failures mutually reinforced each other, so building up cumulatively to support the conclusion that the war was undertaken without sufficient just cause and without adequate planning how to achieve a just outcome following military action to impose regime change. It thus failed the two key tests that have to be met before a war can be justly undertaken, designed to ensure that military action is only initiated if more good than harm is likely to result. By contrast, current coalition operations in Libya are, so far, just. This is a humanitarian operation undertaken to halt a humanitarian catastrophe that is taking place, with wide international support, including authorization by the UN Security Council. Nigel Biggar argues that the fact that the invasion and occupation of Iraq suffered from grave errors, some of them morally culpable, does not yet establish its overall injustice. All wars are morally flawed, even just ones. Further, even if the invasion were illegal, that need not make it immoral. The authority of moral law trumps that of international law, and where the politics of the Security Council prevent the UN from enforcing the law, unauthorized enforcement could be morally justified. Further still, massive civilian casualties do not by themselves make an unjust war. The decisive considerations are those of just cause, last resort and right intention. Proportionality is not among them, because estimating it is far too uncertain. The persistently atrocious nature of the Saddam Hussein regime satisfies just cause; evidence of collapsing containment grounds last resort; and the Coalition's costly correction of early errors proved the seriousness of its good intentions. In sum the invasion and occupation of Iraq was, despite grave errors, justified. Regarding Libya, Biggar notes the recurrence of conflict over the interpretation of international law. He wonders how those who distinguish sharply between protecting civilians and regime change imagine that dissident civilians are to be ‘kept’ safe while Qadhafi remains in power. Against those who clamour for a clear exit‐strategy, he counsels agility, while urging sensitivity to the limits of our power. What was right to begin may become imprudent to continue.     

Gambling,Resource Distribution,and Racial Economy: An Examination of Poker Machine Expenditure in Three Remote Australian Towns

Our aim in this paper is to examine the ways in which electronic gaming machines (EGMs) redistribute resources to and from three remote towns in the Northern Territory (NT), namely Katherine, Tennant Creek and Nhulunbuy. We describe EGM expenditure levels in each town at the level of the individual venue, examine patterns of socioeconomic status within each town, explore the ways in which EGM markets are racialised through venue gate‐keeping practices and spatially‐based alcohol regulations, and examine the effects of resource redistribution mechanisms designed to return a proportion of EGM profits to host communities. The ability of venues to draw resources from extremely disadvantaged groups from the remote periphery is of central concern when attempting to assess the societal consequences of gambling in remote towns, both in terms of individual harm and the adequacy of resource redistribution. Existing mechanisms for resource redistribution are both selective and relatively meagre, pointing to a political and racial economy of EGM gambling that transfers resources from remote towns to sites of centralised ‘white’ power. We conclude that political economy in the context of remote NT towns may not be understood outside a consideration of racial economy and the way that constructed notions of race operate to legitimate existing processes of economic exploitation and resource redistribution.     

Vulnerability to Bushfire Risk at Melbourne's Urban Fringe: The Failure of Regulatory Land Use Planning

The 7 February 2009 bushfires in the peri‐urban region to the north of metropolitan Melbourne heralded what many have called an entirely new epoch in terms of weather‐related disasters in Australia. A total of 173 people and 2000 properties were destroyed and, as with the 1939 fires in Victoria, a Royal Commission was subsequently instituted to inquire into the causes and responses to the fire. The Royal Commission has heard much evidence about alleged failings of fire response, communication and administration. It also considered land use planning issues and the associated regulatory framework. Using the Shire of Murrindindi as a case study, this paper argues that the location of population growth, and associated regulatory failure, are contributory, yet under‐researched, factors associated with life and property losses. The adoption of more robust planning tools which incorporate climate change considerations, we argue, is essential to anticipate and minimise the impacts of disastrous natural events such as bushfires. In the latter part of the paper, attention is drawn to a recent Victorian Civil and Administrative Tribunal decision which is groundbreaking in its use of the precautionary principle to prevent dwelling construction in an ‘inappropriate’ location as well as to some major inconsistencies between planning for flood and bushfire threats.     

THE EFFECTIVE DURATION OF EARTHQUAKE STRONG MOTION

The duration of strong ground shaking during earthquakes can play an important role in the response of foundation materials and structures, particularly when strength or stiffness degradation is encountered. A thorough seismic hazard assessment should therefore include an estimation of the expected duration of strong motion, which first requires criteria to define the part of an accelerogram considered to represent the duration of strong ground motion. Some 30 different definitions of strong motion duration are reviewed and classified into generic groups. Problems that arise with the use of these definitions for duration are highlighted. A new definition of duration is presented using a previously unexplored option which identifies the part of the record where the main energy is contained and constrains this strong shaking phase by absolute criteria. This new definition is shown to give consistently meaningful durations for strong earthquake accelerograms from an engineering viewpoint. The correlations between the new definition of duration and magnitude, soil conditions and distance are explored as a first step towards the development of predictive equations.
