Stable isotope analysis of dog,fox, and human diets at a Late Holocene Chumash village (CA-SRI-2) on Santa Rosa Island,California

Stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope analyses of dog (Canis familiaris), island fox (Urocyon littoralis), and human bone collagen from CA-SRI-2 (AD 130–1830) on Santa Rosa Island, California provide a proxy of diet and the relationships between humans and these animals. Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods. Nitrogen isotopes and archaeofaunal remains indicate that humans and dogs also ate higher trophic level foods, including finfishes, marine mammals, and seabirds with smaller amounts of shellfish. The CA-SRI-2 island foxes appear to have eaten higher amounts of terrestrial foods, similar to the diets observed in modern fox populations. These data generally confirm the commensal relationship assumed to exist between domesticated dogs and people, but the carbon isotopic composition of dogs is enriched ∼2‰ compared to humans. We hypothesize that the difference in carbon isotopes between dogs and humans may have resulted from a higher consumption of C3 plants with lower δ¹³C values by humans, or less likely from the ingestion by dogs of significant amounts of bone collagen, which is enriched by ∼4‰ over associated muscle.     

Ground-Motion Prediction Equations Based on Data from the Himalayan and Zagros Regions

This study derives ground-motion prediction equations for the horizontal elastic response spectral acceleration for 5% damping for application to the Indian Himalayas. The present equations include a consideration of site category (rock/soil) and style-of-faulting (strike-slip/reverse). Due to a lack of near-field data from India, additional strong-motion data have been included from the Zagros region of Iran, which has comparable seismotectonics to the Himalayas (continental compression). A set of 201 records from 16 earthquakes were used within the regression. The derived model predicts similar ground motions to previously published equations for the Himalayan region but with lower standard deviations.     

‘Le Temps du plastique’: The Critique of Synthetic Materials in 1950s France

The increasing pervasiveness of plastics in 1950s France was accompanied by a profoundly ambivalent critique of synthetic materials. Much postwar French culture tended to affirm traditional craft-based production, treating plastics with suspicion. Synthetic materials symbolised a ‘bad’ modernity, the emergence of a new consumer society of mechanised mass production and the death of an older artisanal way of life. More fundamentally, synthetics challenged the very notion of materials itself, questioning through their capacity for imitation and transformation the accepted identities and hierarchies of the material world. Works by Roland Barthes, Roger Vailland, Jacques Tati, Alain Resnais and Raymond Queneau engage with the implications of plastic, revealing a deep ambivalence about social and economic modernisation through their treatment of materials whose simultaneously polymorphous and homogeneous character both seduces and repels. Beginning as a project of demystification, the cultural critique of plastic ultimately reveals its complicity with what it ostensibly rejects.     

Where the battle rages: war and conflict in Post-Medieval Archaeology

SUMMARY: War and conflict has been well represented in Post-Medieval Archaeology over the last 50 years with a range of research exploring the archaeology of conflict in the modern world. The aim of this article is to review themes of war and conflict as presented in Post-Medieval Archaeology and to track the changing nature of their scope and focus, such as the move towards an increasingly multidisciplinary approach encompassing all aspects of human conflict. By highlighting key articles and innovative research, this article also reflects on the impact and influence of the journal on the burgeoning discipline of conflict archaeology.
