Negotiating Remote Borderland Access: Small‐Scale Trade on the Vietnam–China Border

This article explores the cross‐border trading networks and practices of highland residents in north‐west Vietnam. It reveals how such individuals, of highland minority and majority Kinh ethnicities, negotiate the political reality of an international border in highly pragmatic ways as they augment their livelihoods by trading commodities with inhabitants in south‐west China. We follow four particular commodities, traded across different political tiers of border crossing (each with specific rules, regulations and negotiations), by a diverse range of traders. In doing so we argue that border access is mediated by a complex and multifaceted set of social and structural components including not only state policy, but ethnically‐embedded social relations and specific geographic variables that, in turn, are engendering disparate economic opportunities.     

Reevaluating the Age of the Iberomaurusian in Morocco

Chronological evidence for the Iberomaurusian is currently very limited and there are problems with some of the published radiocarbon dates. In this paper we present new AMS dating results from well-stratified cave sequences at Ghar Cahal, Kehf el Hammar and Taforalt in northern and eastern Morocco. The longest of these sequences, from Taforalt, shows an intermittent occupation history spanning the period ca. 18,000–11,000 bp (radiocarbon determinations presented in this paper are expressed as ka bp or bp, whilst approximate calendar ages are expressed as Cal bp) with a marked intensification of cave use soon after ca. 13,000 bp. Using calibrated AMS ages in comparison to sea surface temperature evidence from the Alboran Sea core MD95-2043 and more generally to Greenland ice δ¹⁸O core records, we suggest that there may have been a relationship, albeit a complex one, between climatic events and cave activity on the part of Iberomaurusian populations.     

Model studies in computer seriation

A computer model is described which generates artificial incidence matrices, with statistical properties similar to those of a Merovingian cemetery, but with a known chronological order.These matrices are used to test the effectiveness of various seriation procedures. Both permutation search and multi-dimensional scaling methods are investigated. The effects of various similarity matrix transformations are also discussed.     

Newspaper Reporting on Climate Change,Green Energy and Carbon Reduction Strategies across Canada 1999–2009

Canada’s climate change strategy faces an uncertain future since the country’s withdrawal from the Kyoto Protocol in 2011, making domestic public debate and awareness critical in the search for effective mitigation policies. This article presents a spatio-temporal analysis of newspaper reporting across Canada on climate change and carbon reduction approaches, ranging from renewable energies (solar, wind, hydro power) to carbon management (e.g., carbon capture and storage [CCS]) and economic approaches (e.g., carbon trade, ecological fiscal reform). The findings of a news article keyword analysis show that the overall growth of the Canadian news coverage during this time period was significantly fragmented into isolated peaks of activity rather than continuous growth of the topic of climate change. Furthermore, the study finds a strong news emphasis on technology- and growth-oriented solutions as opposed to a comprehensive ecological modernization that would encourage a deeper structural discussion about Canada’s much-criticized carbon-intensive energy economy.
