Hunter-gatherer tobacco smoking: earliest evidence from the Pacific Northwest Coast of North America

Chemical analysis of residue extracted from stone pipes and pipe fragments excavated at sites in the southern Pacific Northwest Coast of North America demonstrate that hunter-gatherers smoked the psychostimulant tobacco (Nicotiana sp.) by at least AD 860. Non-farming ethno-historic Native Americans throughout the west gathered and sometimes cultivated tobacco for ritual and religious purposes, but until now the antiquity of the practice on this part of the continent was unknown. Method validation includes chemical characterization of a suite of smoke plants and experimental reproduction of “smoked” pipe chemistry; results indicate biomarkers are traceable for several species commonly smoked by ethnographic native peoples, including tobacco (nicotine, cotinine), tree tobacco (anabasine), and kinnikinnick (arbutin). Developed methods—where residue is extracted directly from the stone or clay matrix of whole and fragmentary archaeological pipes—may be applied in similar studies investigating the spread and use of ritual smoke plants in the ancient Americas and elsewhere.     

Hail ambiguous St Patrick: sounds of Ireland on parade in Birmingham

Birmingham's St Patrick's Day parade claims to be the largest of such events in the UK and the third best attended in the world. Despite resorting to universal advertising proclamations that for one day ‘everyone is a little bit Irish’, this annual march continues to foster the unique musical character of the local diaspora; a metanarrative for the wider, fractious journey of the Irish community into the West Midlands over the past sixty years. This paper examines the primary event in Birmingham's calendar by way of the sounds of the spectacle, considering the musical display that is presented in the processional mode to a static audience sharing city-centre streets one Sunday morning every March. By engaging with the theories on performance of Domenico Pietropaolo, Mikhail Bakhtin and Stephen Greenblatt, this paper argues that it is in the audible space of the parade that Birmingham creates Breda Gray's Ireland ‘of global flows’.     

Tools for Predicting Damage to Archaeological Sites Caused by One-Dimensional Loading

Tools are developed to predict damage to archaeological remains caused by the construction of line infrastructure on soft soil. They are based on numerical modelling and laboratory testing supported by X-ray microcomputed tomographic observations, and micromorphological analyses of thin sections. They have been validated for one-dimensional (1D) loading at two sites in the Netherlands where soil has been placed on top of organic layers rich in ecofacts and overlaying Pleistocene sands.

Numerical prediction of the deformation of soft layers underneath an embankment remains a challenge for geo-technical engineers. Errors on surface settlement prediction reach ±15% of the measured total settlement.

Laboratory observations show that vulnerable artefacts can get crushed when packed loosely in pure assemblies under 1D loading equivalent to less than 5 m of sand. Fragmentation is assimilated to loss of archaeological value as it compromises recovery during sieving. Embedment in a sandy or a very compressible organic matrix has a beneficial effect on the resistance of ecofacts. Embedded ecofacts can resist a load of more than 12 m of sand. Flattening and re-orientation of soft plant remains occur during 1D loading without microscopic damage of tissues.     

Philosophy and literature,

Freedom as a natural right, the importance of consent, defending the idea that government should be in the hands of the most virtuous and reflective citizens, denouncing patronage, the need to link individual and political freedom … These are some of the characteristics of La Boétie's doctrine that I believe place him within the tradition that Quentin Skinner calls the neo-Roman conception of civil liberty. Of course, La Boétie did not write a positive defence of the rule of law, as Livy did in his History of Rome and as the English republicans do, but the Discourse can easily be read as a legal plea condemning absolute monarchy and any kind of arbitrary regime.
