The Early Bronze Age settlement of Fidvár,Vráble (Slovakia): reconstructing prehistoric settlement patterns using portable XRF

This paper presents first results of chemical analyses of sediment samples from the Early Bronze Age (EBA) settlement Fidvár near Vráble (Slovakia). Large-scale geomagnetic prospection revealed detailed architectural remains of a fortified settlement. Other structures such as an earthwork of the linear pottery culture and at least two Roman march camps were found too. An Auger programme provided sediment samples of different depths, A) from an EBA house and the outer fortification ditch, B) from a potential metal workshop area as indicated by surface finds, and C) from an area located in the settlement's centre. The samples were analysed by a portable X-ray fluorescence (pXRF) spectrometer in order to investigate the vertical and horizontal distribution of chemical signatures. The comparison of geophysical data and three-dimensional chemical patterns gives us the opportunity to determine the human impact and to reconstruct activity patterns. The potentials and limits in the application of pXRF in archaeological soil chemical surveys are evaluated by systematic comparisons with high resolution laboratory measurements, including atomic absorption spectrometry (AAS) and inductively coupled plasma optical emission spectrometry (ICP-OES). The pXRF analyses can be reproduced well and show a good accuracy. Whilst (p)XRF analyses reflect the total composition of archaeological soil samples, the results of the AAS and ICP-OES analyses are fundamentally influenced by the acid digestion or extraction methods used. The pXRF analyses of the Vráble soils showed typical patterns of human occupation. For example, there are strong positive correlations between phosphorous, strontium and calcium. Phosphorous shows an enrichment in pathways and the fortification ditch. It is less strongly enriched within the sediments of house structures. Similar results apply to calcium and strontium distribution. But compared to the respective concentrations in sediment samples from the ditch they show a considerably higher variation in samples associated with house structures; that is, individual samples of sediments from house structures contained high concentrations of both, calcium and strontium. The deposits of an area that according to surface finds was thought to represent a potential metal workshop did not show indicative chemical signatures. Targeted excavations confirmed the absence of such as workshop. Finally it was shown that the refill history of the innermost fortification ditch (sample area D) and the overall cultural occupation sequence at the site correlate strongly with the chemical signatures of the respective ditch profile. The systematic variation of key elements along the profile opens up an entirely new perspective for interpreting the site's history. Overall, the study shows the great potential of pXRF as valuable part of an archaeological survey toolkit.     

A Rogue is a Rogue is a Rogue: US Foreign Policy and the Korean Nuclear Crisis

Two nuclear crises recently haunted the Korean peninsula, one in 1993/4, the other in 2002/3. In each case the events were strikingly similar: North Korea made public its ambition to acquire nuclear weapons and withdrew from the Nonproliferation Treaty. Then the situation rapidly deteriorated until the peninsular was literally on the verge of war. The dangers of North Korea's actions, often interpreted as nuclear brinkmanship, are evident and much discussed, but not so the underlying patterns that have shaped the conflict in the first place. This article sheds light on some of them. It examines the role of the United States in the crisis, arguing that Washington's inability to see North Korea as anything but a threatening 'rogue state' seriously hinders both an adequate understanding and possible resolution of the conflict. Particularly significant is the current policy of pre-emptive strikes against rogue states, for it reinforces half a century of American nuclear threats towards North Korea. The problematic role of these threats has been largely obscured, not least because the highly technical discourse of security analysis has managed to present the strategic situation on the peninsula in a manner that attributes responsibility for the crisis solely to North Korea's actions, even if the situation is in reality far more complex and interactive.     

Palaeolithic and Neolithic Occupations in the Témara Region (Rabat, Morocco): Recent Data on Hominin Contexts and Behavior

In the 1970s, the discoveries of Palaeolithic human remains in the caves of Dar es Soltane 2, El Harhoura 1 and Les Contrebandiers reinforced interest in the sites of the Témara region. These sites, often cited, have been the object of numerous investigations which have produced a major contribution to the prehistory of Morocco. Over the past 15 years, research at two key sites, El Mnasra and El Harhoura 2, have considerably enhanced the available data for this region. Preliminary results obtained from excavations since 2001, allow us to present the palaeoenvironmental framework and describe the technological behaviour of prehistoric groups within a re-evaluated stratigraphic context. The microfaunal and macrofaunal assemblages are analysed according to systematics, taphonomy and palaeoecology. The lithic and bone industries document patterns of raw material acquisition and transformation. Within the context of the history of more than 60 years of research in the region of Témara, this contribution allows us to approach the question of Palaeolithic population on the basis of recent, and for the most part new, data and evidence.     

CBC News Coverage of Canada's 2006 Liberal Party Leadership Candidates

Content-coded CBC evening newscasts are used in this article to examine reports on the eight candidates for Liberal Party leader in the weeks before the party's 2006 convention. In a sharp contrast to news reports on US presidential nominations, The National provided coverage balanced between the horse race and more substantive matters, including policy discussions and a candidate's personality and leadership qualities. But as with US nomination coverage, The National largely ignored trailing candidates, focusing nearly all its attention on the likely and plausible nominees. In terms of tone, The National provided “compensatory coverage,” where front-runners were treated more negatively than the candidates who were further back in the field.
