Archaeological fish bones reveal increases in marine fish utilisation in Northern and Western Europe beginning in the 10th and 11th centuries AD. We use stable isotope signatures from 300 archaeological cod (Gadus morhua) bones to determine whether this sea fishing revolution resulted from increased local fishing or the introduction of preserved fish transported from distant waters such as Arctic Norway, Iceland and/or the Northern Isles of Scotland (Orkney and Shetland). Results from 12 settlements in England and Flanders (Belgium) indicate that catches were initially local. Between the 9th and 12th centuries most bones represented fish from the southern North Sea. Conversely, by the 13th to 14th centuries demand was increasingly met through long distance transport – signalling the onset of the globalisation of commercial fisheries and suggesting that cities such as London quickly outgrew the capacity of local fish supplies. 相似文献

The scientific interrelationships between Italy and Germany in the 18th and 19th centuries — a hitherto neglected area of research — are discussed in an overview according to the following ten dimensions: language knowledge and translations; reviews and bibliographies; library content; personal contents and correspondance; travel reports and travel guides; diaries and autobiographies; university studies and research sojourns; membership in academies and scientific societies; practical and theoretical resonance; comparisons to other countries. This approach, which has to be concretized in future studies, promises at the same time general insights into the logic of science and its progress. 相似文献

A new method is proposed to map firms' principal market areas using shipment data. The new method is a general one which could prove just as useful in mapping the incidence of disease as in mapping market areas. This method is applied to agricultural data for feeder cattle sales at a video cattle auction. Transportation costs appear to be the main determinant of market area boundaries, but there are many cases where transportation costs alone cannot explain the market areas found. The size and shape of market areas for feeder cattle buyers are large, irregularly shaped, and extensively overlapping. 相似文献
