Condemned to metallum? The origin and role of 4th–6th century A.D. Phaeno mining campresidents using multiple chemical techniques

The Byzantine period (4th–7th centuries A.D.) site of Khirbet Faynan (Phaeno) was a state-run mining camp described in ancient sources as a destination for Christian martyrs and others prosecuted by the administration who were condemned to the mines (damnatio ad metallum). However, other evidence suggests that Phaeno had a much broader role and population in antiquity than that described by ancient writers. Here, strontium and oxygen isotope data on the level of migration into Phaeno were compared with elemental data on lead and copper skeletal levels to illuminate the varied exposure of local vs. non-local individuals to contaminated environments (presumably from working in mining and smelting operations). Dental enamel ⁸⁷Sr/⁸⁶Sr and δ¹⁸O data from 31 individuals excavated from the Southern Cemetery identified one individual born in a region with different strontium isotope values in the bedrock yet similar oxygen isotope signatures as Faynan. Most of the primarily locally-derived Faynan residents displayed skeletal copper and lead levels exceeding those seen in comparative samples, confirming that growing up and residing in the polluted environment of Faynan led to notable bioaccumulation of heavy metals and its resulting health effects. In addition, ten individuals had extremely elevated lead and copper levels in their skeleton resulting from more intensive exposure to contaminated environments, possibly through smelting and mining activities. These data confirm the relatively localized nature of this imperial operation and that this predominantly locally-derived population had different activities that put them ask varied risk for contamination by heavy metals.     

Metallurgical analysis of copper artifacts from Cahokia

Copper artifacts from Cahokia Mounds, Illinois were analyzed from a materials science perspective to shed light on techniques used by Mississippian copper workers to deform nuggets of native copper into thin sheets. Eight small copper pieces from a copper-working site at Cahokia’s Mound 34 were subjected to metallographic examination. Replication experiments thereafter recreated features of the artifacts under controlled conditions. It is concluded that copper sheets were thinned through repeated cycles of hammering and annealing performed at temperatures achievable in an open wood fire. The welding of sheets to create multilayered objects was not observed in any artifacts and could not be accomplished experimentally. Additionally, a possible cutting method used on some artifacts was identified.     

Subsistence and the isotopic signature of herding in the Bronze Age Hexi Corridor,NW Gansu,China

Dietary patterns at two Bronze Age sites in the Hexi Corridor are investigated by the analysis of stable carbon and nitrogen isotopes in faunal bone collagen. The findings are compared with archaeobotanical remains from one of the sites which include high proportions of millet (Panicum miliaceum and Setaria italica) as well as the western derived cereals wheat (Triticum aestivum), barley (Hordeum vulgare) and oat (Avena sativa). The isotopic data indicate domestic omnivores (Canis and Sus) had diets dominated by millet. Minimally offset δ¹⁵N values between herbivore and omnivore fauna suggest low consumption of animal protein by omnivores. Diets of herded animal (Bos and Caprinae) included only low proportions of C4 foods, suggesting that these animals were not regularly foddered with millet plants, and that their grazing areas were mostly beyond the agricultural zone. The wide range in δ¹⁵N values amongst herbivore fauna (4.1‰–11.8‰) suggests grazing occurred in a variety of ecological zones, and this would be consistent with the occurrence of long-distance transport of livestock in the region.     

Hardwood ash nixtamalization may lead to false negatives for the presence of maize by depleting bulk δC in carbonized residues

Among the multiple proxies for detecting maize in precontact economies is the use of δ¹³C analysis of carbonized residues from ceramic cooking vessels. Although maize horticulture was widely established in Eastern North America (ENA) by A.D. 1000, there are carbonized residues from ceramic assemblages after this date that lack the elevated δ¹³C values indicative of the presence of maize. This may be due to the true absence of maize, or other factors including the masking of maize. Prior experimental research by Hart et al. demonstrated that the addition of C₃ plants or consumers to two part mixes with maize can mask maize presence even when maize is the dominant ingredient. Here we investigate the effect of alkali processing of maize (nixtamalization) on δ¹³C using the widespread ENA process of boiling maize kernels with wood ash, a C₃ product, to create hominy. Our experiments test whether or not the process of hardwood ash nixtamalization can mask the presence of maize in adhering carbonized residues by depleting δ¹³C values, and whether there is a reciprocal δ¹³C enrichment effect on the hardwood ash employed in nixtamalization. Overall, there is substantial δ¹³C depletion of residues when maize is cooked with hardwood ash, and hardwood ash cooked with maize shows the reciprocal enrichment. Therefore, the depleted values after the adoption of maize may be false negatives due to the nixtamalization process.     

Obsidian sources and distribution systems in Island Southeast Asia: new results and implications from geochemical research using LA-ICPMS

This paper discusses new evidence of long-distance interaction networks in Island Southeast Asia obtained from geochemical analyses using SEM-EDXA and LA-ICPMS of 101 obsidian samples from 25 locations including seven obsidian sources and 19 archaeological sites. Given that there are obsidian sources distributed throughout much of Island Southeast Asia, the potential for obsidian studies to provide greater understanding of patterns of mobility and exchange in the Pre-Neolithic and Neolithic periods would seem to be considerable. This potential, however, remains largely unrealised as obsidian sourcing has hitherto only been carried out intermittently in Island Southeast Asia using PIXE-PIGME, XRF and other methods.     

The Romney Street Group: Its Origins and Influence--1916-1922

Contemporary historians tend to be drawn to study formal institutions,largely because they leave formal records. But as politicalscientists have long argued, informal networks can be of equalimportance and influence. Throughout the last century, dininggroups were amongst the most common of these networks; and theRomney Street Group, which has been existence in various guisessince 1917, is eminent amongst them. This article looks at themethodological problems of analysing such groups, as well asits early history. Amongst its early members were R.H. Tawneyand Tom Jones, symbolizing the link the group forged betweenthe liberal intellectuals behind The Athenaeum and Lloyd George'snewly formed Cabinet Secretariat. Its principal focus was thepostwar reconstruction of industrial and international relations.Although its immediate impact appears to have been small, itcontinued to keep reconstruction ideals alive, in general throughjournalism and the private contacts of its members and in particularthrough Tom Jones, who was successively the confidant of LloydGeorge and Baldwin.     

The Dualism of Urban Governance in Denmark

The article argues that the present Danish urban policy and urban democracy can be characterized by a striking duality and tension between: (1) Participatory empowering welfare oriented community strategies, which targets deprived districts and neighbourhoods, which are based on notions of the inclusive city. This trend is founded on priorities of radical democracy, social justice, inclusion and citizens empowerment; (2) Neo-elitist/corporative market driven strategic regional and global growth strategies, which are based on notions of the Entrepreneurial Globalized City and where urban policy becomes a question of facilitation of the “growth machine” and neo-liberalized urban authoritarianism. The article discusses dilemmas for overcoming the growing tension between elitist neo-corporate growth regimes, which are in operation via “Quangoes” and closed elite networks, and community empowerment and welfare oriented policy in the age of globalization. Taking the stand of community empowerment and welfare policy, the article conclusively discusses ways to shape a new inclusive politics of difference including using “positive selectivism” as part of an empowerment strategy.

Her article is preceded by four papers that pay tribute to Jan Monk's academic achievements and her dedication to encouraging and guiding the careers of emerging scholars around the world.     

Religion and Politics in the Howard Decade

The interaction between religion and politics is varied, complex and often heated. It involves constitutional issues, voting behaviour, party composition and electoral competition, faith-based public administration, advocacy and lobbying by churches, mutual criticism by churches and the state, and the public presentation of religious values. This article is a comprehensive mapping and discussion of a range of the major religion and politics issues in Australia since the election of the Howard government in 1996. This has been a decade in which religion has had a higher political profile than at any time since the 1950s Labor Split. One feature has been the rise to prominence of Catholics in the Coalition parties, whereas they featured heavily on the other side during the Labor Split. It is a more intellectually interesting decade than the 1950s because the influence of religion has crossed denominational and faith boundaries from the mainstream Christian churches to the newer Evangelical Christian churches and to non-Christian religions such as Islam. The overall impact of religious intervention appears to have favoured the Coalition parties, but many unanswered questions remain about the motivation and impact of these developments, and there are numerous opportunities for further research.     

Representation and Recursion in the Archaeological Record

Living humans are unique among the animal kingdom with respect to their ability to externalize mental representations outside the brain through a variety of media and in a recursive or creative manner (i.e., generating a potentially infinite array of combinations). Earlier humans evolved two specialized organs—the hand and the vocal tract—as primary instruments for externalizing artificial or semantic representations. These organs and the externalized representations may have co-evolved with the Homo brain. The archaeological record yields examples of simple representations by 1.6 mya. More complex, hierarchical, and recursive forms are evident by roughly 0.25 mya. Complex and highly recursive representations in a wide range of media (including representations of representations in the form of visual art) emerge after 0.1 mya among anatomically modern humans.
