New Zealand and Chile: partnership for the Pacific century?

The research note investigates the growing economic and political interaction between two important Pacific Rim players, Chile and New Zealand, and analyses the rationale for the Closer Economic Partnership that is currently under discussion. Having analysed the data on trade between the countries it suggests that a mixture of strategic and symbolic geopolitical/geo‐economic factors are driving the agreement rather than the desire to increase bilateral commodity exchange. As it is presently constructed, the agreement is likely to bestow disproportionate benefits on specific corporate actors in certain sectors. A research agenda for monitoring the broader impacts of the agreement is offered.     

Local Histories,Global Markets: Cocoa and Class in Upland Sulawesi

Research and policy concerning the Southeast Asian uplands have generally focused on issues of cultural diversity, conservation and community resource management. This article argues for a reorientation of analysis to highlight the increasingly uneven access to land, labour and capital stemming from processes of agrarian differentiation in upland settings. It draws upon contrasting case studies from two areas of Central Sulawesi to explore the processes through which differentiation occurs, and the role of local histories of agriculture and settlement in shaping farmers’ responses to new market opportunities. Smallholders have enthusiastically abandoned their diversified farming systems to invest their land and labour in a new global crop, cocoa, thereby stimulating a set of changes in resource access and social relations that they did not anticipate. The concept of agency drawn from a culturally oriented political economy guides the analysis of struggles over livelihoods, land entitlements, and the reconfiguration of community, as well as the grounds on which new collective visions emerge.     

Archaeological research on HMS Swift: a British Sloop-of-War lost off Patagonia, Southern Argentina, in 1770

HMS Swift was a British sloop-of-war which sank off the coast of Patagonia, Southern Argentina, in 1770. Since 1997 the Underwater Archaeology Programme of the National Institute of Anthropology has taken charge of the archaeological research conducted at the wreck-site. This article presents an overview of the continuing Swift project and the different research lines comprised in it. The latter cover aspects related to ship-construction, material culture and natural site-formation processes.

Stability of IRSL signals from sedimentary K-feldspar samples

Recent work has identified IR stimulated luminescence signals at elevated temperature from both potassium- and sodium-rich feldspars that have much lower anomalous fading rates than the conventional signal measured using IR stimulation at 50°C. This paper examines the stability of these signals for potassium-rich sedimentary feldspars. We show that the natural post-IR IRSL (pIRIR) signal from a 3.6 Ma old sample is in apparent saturation on a laboratory generated dose response curve, i.e. it does not show detectable fading in nature although a low fading rate is observed on laboratory time scales. We show that the pIRIR signal has a greater thermal stability than the IRSL signal and that the trend in increasing thermal stability is mirrored by a decreasing fading rate. We also investigate the effect of preheat temperature and IR stimulation power on the decay shape and conclude that the data can be explained in terms of either a single- or multiple-trap model. We present evidence that may suggest that at least part of pIRIR signal is derived from a high temperature trap (∼550°C thermoluminescence (TL) peak), although again the data can also be explained in terms of a single-trap model. Finally, we present dose response curves and characteristic curvature constants (D₀) values for various IRSL signals and conclude that the more stable signals saturate more quickly than the less stable signals and that the initial and final signals saturate at approximately the same level.
