Archaeological evidence for coastal shellfish exploitation in Arctic Norway mostly dates from 5300 to 1500 BC, encompassing the terminal Mesolithic, the Late Stone Age, and the beginning of the Early Metal Period. Shell middens are generally associated with semi-subterranean houses, but may also occur as free-standing deposits. The primary shellfish taxa exploited were Littorina littorea, Arctica islandica and Mytilus edulis. Most of the species utilized were available in the littoral zone and were easily procured in the course of daily household activities, but sub-littoral A. islandica would have required greater investment in procurement technology and time, as well as labor cooperation. Shellfish were an occasional dietary supplement and could also serve as fishing bait. Spatial and temporal variation in shellfish assemblages reflects local marine ecology, sea-level changes, household dynamics, and perhaps field processing. Interpretation of the existing data is constrained by inadequate midden sampling and documentation methods.  相似文献

Some French writers, most notably Jean-Baptiste Duroselle and André Tardieu, have argued that French strategic interests during the early decades of the twentieth century had been seriously harmed because, alone among the Great Powers of Europe, France lacked a ‘diaspora’ in the United States. As a result of this, they have claimed, France had no advocacy group prepared to defend the interests of the European ‘kin state’ at a time when France’s great rival, Germany, was amply endowed with a sizeable demographic presence in the United States, willing to speak out in defence of Germany and its foreign policy. Moreover, a second large European diaspora had become established in the United States, whose numbers would swell after the mid nineteenth century: the Irish. Not necessarily committed to promoting German interests, the Irish-Americans did militate strongly and consistently against British interests, such that by the time France and Britain had become close security partners preceding and during the First World War, what worked against British interests would also work against French ones. This article constitutes a critical examination of the Duroselle-Tardieu thesis regarding France's allegedly ‘missing’ diaspora, and cautions against attributing too much geo-strategic influence to either the German-American or Irish-American ‘lobby’.  相似文献

Abstract

A century and half ago, the encounter between the researcher and those (s)he researched were described and seen from the vantage point of the researcher. ‘The others’ participated in the encounters, but were seldom asked for advice regarding the approach or to provide their own perspectives. But this has changed. Originally playing the passive role of the objects of research, today the Sami and Kven of northern Norway have taken on the role of the active participant. These changes are apparent when examining research on the Lule Sami in Norway over the last 150 years. Several dimensions must be considered. First, the researcher and their research must be placed and understood within the contemporary ideological context, implying that the situation of the researcher will reflect the social and political conditions of the time. Analysis of research from the Lule Sami area demonstrates how the researcher's perspective on the Sami people and culture has changed over time, how the Sami role in history, and thus cultural diversity, has been revealed in greater detail, and how the Sami part of the population has increasingly participated by taking on the role of the researcher. Finally, the encounter is analysed in an international context, which shows how the local and national changes are also part of an international development.  相似文献

The maritime fur trade (1785–1840s) led to the local extinction of sea otters (Enhydra lutris) in many parts of the northeast Pacific. On the basis of studies of extant sea otter populations, it has been established that they have a disproportionate effect on nearshore ecosystems by limiting sea urchin abundance and facilitating the establishment of nearshore kelp forests; in the absence of sea otters, a local reduction in kelp-derived carbon is therefore expected. We measured the isotopic composition (δ13C and δ15N) of rockfish (Sebastes spp.) bone collagen from late Holocene archaeological sites in southern Haida Gwaii, BC, Canada, using δ13C as a proxy for kelp-derived carbon in the diet and δ15N as a proxy for trophic position. We observed significant spatial variability in rockfish kelp-derived carbon (δ13C), but not trophic level (δ15N). Kelp-derived carbon varied largely as a function of site characteristics (wave exposure), suggesting that local oceanographic conditions are important factors with respect to consumer tissue isotopic compositions. Kelp-derived carbon decreased in post-European contact rockfish relative to pre-European contact rockfish, likely as a result of the reduction of kelp forests associated with the local extirpation of sea otters. Although we detected a reduction in kelp-derived carbon in rockfish diets, we found no shift in trophic level at sites occupied following the maritime fur trade. This implies a shift in local ecosystems, and particularly in carbon sources, following the maritime fur trade, likely due to a trophic cascade resulting from the local extirpation of sea otters. Stability in rockfish trophic levels, however, implies that rockfish continued to feed at similar trophic levels, consuming prey with similar nitrogen isotopic compositions.  相似文献

Remains of boathouses from the Iron Age and the Medieval Period have been studied for classifying and dating purposes. A classification based on the ratio length/breadth is compared with the height above sea level and tested by 14C‐dates, the measurements of preserved boats and ships, and archaeological finds. It is possible that we can define three groups of boathouses belonging to three different chronological periods. The distribution of large boathouses indicates a different naval organization during the Medieval Period than in the Late Roman/Migration Period. During the Medieval Period the coastal area was divided into many local districts, and each of them had to contribute to the king's fleet with a fully equipped ship. The Iron Age boathouses are found in groups, and it is suggested that the country was then divided into several chiefdoms, and the boathouses were concentrated around the chieftains’ administrative centres.  相似文献
