Putting the border in place: customs regulation in the making of the Irish border, 1921–1945

This paper explores the historical geography of the making of the Irish border through a focus on the practices of customs regulation through which it was constituted and on the impeded, permitted and concealed mobilities of people and objects across the customs boundary after 1923. It traces how legislative change at the level of the state – in this case the governments of the Irish Free State, Northern Ireland and the United Kingdom – was translated into the routine practices of those trying to regulate the movement of people and objects across the customs boundary, and considers the responses of those subject to, and regularly subverting, these efforts. Drawing on recent interests in the prosaic practices of the state, and in materiality and mobility more widely, our focus is both on the work of political power at the border through the practices, texts, tools and techniques of customs regulation, and on the experience and effects of customs control for those living near the newly defined line between Northern Ireland and the Irish Free State.     

An Analysis of Arrow and String Bag Craft Variability in the Upper Sepik and Central New Guinea

ABSTRACT This paper describes an analysis of relationships between language, geography and material culture in the upper Sepik region of New Guinea. We used Mantel tests and principal coordinate analysis to assess and compare the associations between arrow and string bag crafts and language and geographical distance. The Mantel tests resulted in a significant association between each class’ craft variability and both geographical distance and language, however, after statistical control was applied to either of the independent variables only a significant association with geographical distance remained. We argue that these results indicate craft techniques were readily disseminated and that craft distributions are unlikely to reflect any deeper historical relationships between groups. The spatial autocorrelation of arrow crafts was particularly great. A comparison of the principal coordinate analysis plots indicates a greater degree of diffusion and synthesis had taken place between lowland and highland arrow craft traditions. We conclude that the more intensive learning regimes needed to master string bag craft techniques, as well as a greater degree of interdependence between string bag components, had ensured more abrupt differences between bag types resulting in a more moderate degree of spatial autocorrelation.     

Obsidian types from Holocene sites around Lake Turkana,and other localities in northern Kenya

Obsidian has been widely used by early Holocene hunter-gatherers and succeeding Pastoral Neolithic peoples in northern Kenya. Here we report the results of over 2000 electron microprobe analyses of artifactual and non-artifactual obsidian from the greater Lake Turkana region. Of the 15 compositional types of obsidian observed, a preponderant type is widespread across the region from the Barrier in the south to Ileret in the north and east as far as Kargi. This obsidian is the principal type at Lowasera and most Pastoral Neolithic sites, including the Jarigole Pillar site and Dongodien (GaJi4). The source of this obsidian is not known, but based on its distribution the source may be located on the Barrier or in the Suguta Valley immediately to the south of Lake Turkana. Although there are several possible sources of local obsidian identified for minor types, in stark contrast to the central part of the Kenyan Rift, major sources of obsidian available for artifact manufacture are not known in the Lake Turkana region. The lack of obsidian from demonstrable Ethiopian Rift and central Kenyan Rift sources, and the absence of obsidian with compositions found at the Turkana area sites in assemblages in the central part of the Kenyan Rift suggests that the earlier Pastoral Neolithic peoples around Lake Turkana interacted with each other, but perhaps not as strongly with people farther south along the Rift Valley, even as herding practices were expanding to the southward into central Kenya.
