Compared to elsewhere in Oceania, the history and character of stone axe‐adze production and exchange in the Bismarck Archipelago is very poorly known. To explore the feasibility of using geochemical analysis to trace past social interaction, we conducted a non‐destructive portable XRF study of 97 ground stone artefacts from archaeological contexts in New Britain and the ethnographic collection at the Australian Museum. The study capitalised on the well‐documented spatial distribution of geochemical variation resulting from the plate‐tectonic history of the region. The results indicate that prehistoric communities in New Britain specialised in goods such as ground stone tools or obsidian in order to facilitate social interaction over a large region.  相似文献

ABSTRACT The Bayesian calibration program OxCal v.4.1.5 is applied to two chronological datasets for early Lapita derived from two comprehensive reviews. The two datasets are supplemented by published ages for early Lapita sites in two key island groups within Remote Oceania: Vanuatu and Fiji. The analyses provide statistically robust chronologies for the emergence of Lapita on Mussau at 3470–3250 cal BP and in the rest of the Bismarck Archipelago at 3360–3240 cal BP. After a period of 130–290 years, Lapita dispersed to Vanuatu by 3250–3100 cal BP and to Fiji by 3130–3010 cal BP.  相似文献

Contemporary concerns about food safety and regulation haveimportant historical antecedents in the Victorian debate aboutfood adulteration which led to the 1875 Sale of Food and DrugsAct, the basis of British food law until 1955. This articlereconsiders the optimistic historiographical view of the Victorianfood legislation, emphasizing its limited impact on the generalprocess of food production and distribution before the SecondWorld War. In the 1930s adulteration was still a significantcommercial ploy. The analysis centres on State-business relations,drawing comparative perspectives from the manner in which bigfood companies shaped the regulatory framework in the USA. InBritain the government assumed a limited regulatory role, persuadedin the 1920s and 1930s that market forces and the commitmentof large producers to quality and scientific research were betterguarantees of safety than statutory legislation. But this wasa risky strategy: big producers were only responsible for aminority of overall output, and the State made no effort toexamine wider manufacturing conditions. *This article has been written with the assistance of a grantfrom the Leverhulme Trust.  相似文献

During the last fifteen years the Canadian retail landscape has been transformed by the growth and clustering of big box retailers into a range of 'power retail' developments. This has brought new retailers into Canada (predominantly U.S. retailers) with different business strategies that have lead to different consumer behaviour. The power retail phenomenon encompasses all aspects of the retail offer (price, product, service, etc.) and is not simply about the size of stores. These developments have led to new types of commercial clusters—power centres and power nodes—that have challenged both planning policy and the existing retail hierarchy across Canada, and conversely, provided substantial scope for retailers and developers to exploit market opportunities. The article discusses the alternate definitions of power retail, estimates the magnitude of this activity, and examines the spatial pattern and preferences of these new retail locations. The development of power retail is tracked across Canada and regional variations examined. The key trends in power retail growth are identified and potential directions for future development suggested.  相似文献
