Stratigraphy and geochronology of La Playa archaeological site,Sonora, Mexico

La Playa archaeological site in northern Sonora, Mexico contains a long record of human activity that includes the Paleoindian period (terminal Pleistocene) and much of the Holocene. The size and complexity of La Playa has discouraged a systematic characterization of its stratigraphy and geochronology, a deficiency we redress in the study. We distinguished seven stratigraphic units ranging in age from >44,570 to 400 cal yr B.P. using ¹⁴C dates from charcoal and terrestrial gastropods found mostly in archaeological features. All of the buried (in situ) cultural remains are contained in Units B (4690–1580 cal yr B.P.) and C (1010–400 cal yr B.P.) and represent overbank deposition from the nearby Rio Boquillas. Occupation at the site peaks in Units B₄ and B₅, corresponding to the Cienega phase (2800–1800 cal yr B.P.) of the Early Agricultural period. This period coincides with the growth of early agricultural villages in the region and is marked at La Playa by thousands of archaeological features including roasting pits, human burials, and extensive canal irrigation systems. The presence of semi-aquatic and aquatic snails demonstrates that water was present year round in the canal systems constructed during this period. Stable and radiometric isotopic evidence suggests that early agriculturalists diverted ground water over several kilometers from the nearby Rio Boquillas. The extensive Cienega phase occupation ended after about 1700 cal yr B.P. with deep erosion of the site, an event also visible in alluvial records in southern Arizona that marked the end of the Early Agricultural period and significant changes in settlement organization in the region.     

Jasbir K. Puar,Terrorist Assemblages: Homonationalism in Queer Times

The importance of studying human–animal relationships and animal subjectivity is increasingly recognised by social and cultural geographers, particularly in agricultural pursuits. Little research, however, has been undertaken on animals in sport, resulting in a limited understanding of the perceptions and treatment of animals in society. To address this concern, we interrogate print media coverage of the construction and positioning of horses and humans in the controversial activity of jumps racing (National Hunt) in Australia between February 2008 and December 2009. We highlight the importance of seemingly contradictory human–animal relationships involving close frequent contact of some jumps racing advocates in contrast to the distanced, mediated relationships of jumps racing opponents. This paper highlights how the particular activity of jumps racing generates specific human–animal relationships and emphasises the need to reflect on the attitudes that shape and constrain human–animal relationships in varying contexts, including how these attitudes are mediated and the potential consequences for humans and other animals. These findings form the basis for a suggested research agenda that recognises the importance and articulation of proximity and mediation in human–animal relationships, particularly those focused on activities labelled ‘sport’.     

Starch granules,dental calculus and new perspectives on ancient diet

Recent work in various parts of the world has suggested the possibility of ancient starch granules surviving and adhering to archaeological artefacts. Often this information is used to infer aspects of diet. One additional source for recovery of archaeological starch granules is dental calculus. The presence of plant food debris in dental calculus is well known but has not been not widely investigated using archaeological material. The extraction of starch granules from dental calculus represents a direct link to the consumption of starchy food by humans or animals. Using dental calculus also sidesteps many other questions still inherent in using starch granules to reconstruct aspects of ancient diet, such as the effects of diagenesis on their morphology; as the starches are trapped inside a concreted matrix they are less likely to alter over time. We used amylase digestion by a starch-specific enzyme to confirm the material as starch.     

Parity is about 'race': French republican citizenship and the French Caribbean

This article considers both the racialised and the gendered nature of citizenship in France, combining a reading of the construction of French citizenship and its exclusive nature with a discussion of the implications of the parity debate for other social categories besides gender. A historicised consideration of the French concept of citizenship is followed by a brief account of the place of the French Caribbean and its population in the Republic, emphasising the role played by the republican tradition in the exclusion of both French West Indians and French women. The article argues that gender parity leads to the discussion of other categories of difference, such as 'race', and demonstrates the need for more engaged debate of this issue.
