Gao and Igbo-Ukwu: Beads, interregional trade, and beyond

Recent excavations in the city of Gao in eastern Mali have uncovered a sizable assemblage of imported and locally produced beads which are similar in many ways to the beads excavated at the site of Igbo-Ukwu in Nigeria. The similarities between the two assemblages suggest that they are indicative of interregional trade along the River Niger. As the likely source of many of the beads is Fustat in Egypt, Gao may well have been the middleman between Igbo-Ukwu and the former site. This route, it is argued, is more satisfactory than a direct east-west trade across the Sudannic zone, which has been argued for previously as a channel of international trade for Igbo-Ukwu.

An integrated assessment of archaeobotanical recovery methods in the Neotropical rainforest of northern Belize: flotation and dry screening

This report presents results of a study examining the ancient use of plants at four Late Classic (CE 600-900) Maya rural farmsteads in northwestern Belize. Our research specifically targeted residential middens for macrobotanical recovery. Samples yielded the remains of more than a dozen plant families, representing some genera that do not currently grow in the area. These plants were used in the Late Classic, countering the idea that ancient botanical remains do not survive in Neotropical archaeological contexts. We also evaluated two macrobotanical sample processing methods vis-à-vis one another: flotation and dry screening. Our results indicate that flotation recovered 58% more seeds than dry screening, while dry screening yielded almost twice as much charcoal and other wood as flotation. The divergent quantities in the types of material recovered suggest a comprehensive macrobotanical recovery program should include the use of both processing methods.     

The use of strontium isotopes as an indicator of migration in human and pig Lapita populations in the Bismarck Archipelago,Papua New Guinea

This paper examines the potential use of strontium isotopes (⁸⁷Sr/⁸⁶Sr) for identifying migration within Lapita populations and their commensal animals, specifically the pig (Sus scrofa). Lapita people (ca. 3300–2200 BP) were the initial colonists of the island groups to the east of the Solomon Islands, spreading from Papua New Guinea to Tonga and Samoa within a few centuries. Mobility is assumed to have been an important mechanism for maintaining cultural solidarity between Lapita communities. It has been previously argued that Lapita populations became progressively more sedentary over time after the initial colonising events. Two Lapita sites, Kamgot and Balbalankin, from the Anir Islands in the Bismarck Archipelago are included in the analysis and fall within the Early (ca. 3300–3000/2900 BP) and Middle (ca. 3000/2900–2700 BP) Lapita periods respectively.     

Underwater Excavation at Ederline Crannog, Loch Awe, Argyll, Scotland

A trial excavation was carried out on the near-submerged crannog at Ederline Boathouse, Loch Awe, in July 2004. A trench measuring 3 × 5 m was opened on the northern side, in c .3 m of water. Around 1 m of organic deposits was encountered, along with structural timbers and animal bones. Despite a previous 4th century BC radiocarbon determination from a structural timber, a sherd of E ware from a sealed context gives an Early Historic date for the deposits excavated in 2004. The results from this first intrusive investigation of a Loch Awe crannog demonstrate that these sites are complex and long-lived.

Women Workers and the Promise of Ethical Trade in the Globalised Garment Industry: A Serious Beginning?

The paper gives an overview of the recent development within the Ethical Trade Initiative (ETI), especially the development of corporate codes of conduct, and considers the prospects they offer for improving labour conditions for workers in the international garments industry. It argues that two specific features of the industry—competitive production systems based on international subcontracting and the use of predominantly female production workers—are likely to undermine the effective development of a codes-based strategy. Nevertheless, the labour rights agenda at the centre of ETI does provide a space for labour activists, whether operating in or out of formal union structures, to build campaigns and connections around global production networks.
