Harvesting different species as foods or raw materials calls for differing skills depending on the species being harvested and the circumstances under which they are being taken. In some situations and for some species, the tactics used are mainly behavioral—that is, people adjust, or adapt, their own actions to fit the behavior and circumstances of the species they are taking. Under other circumstances and for other species, the skills and tactics used may call for greater environmental preparation or manipulation. Therefore, instead of trying to distinguish people today and in the past as either foragers or farmers, it makes sense to define human subsistence behavior as an interactive matrix of species and harvesting tactics, that is, as a provisions spreadsheet.  相似文献

Fourteen glass objects recovered from excavations at the ancient city of Tall Zirā‛a, Jordan, were analysed using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to determine the period and origin of manufacture. The composition of glasses manufactured in the Late Bronze Age (LBA) and Iron Age are distinctly different, therefore major element analysis can be used to distinguish between the groups relatively easily. The LA-ICP-MS analysis provided quantitative trace element data which were used to determine the provenance of those glasses identified as LBA. This research discusses the implications of the presence of both Egyptian and Mesopotamian LBA glasses and examines the varying compositions and colour strategies employed in both the LBA and Iron Age objects. Specifically, glass in the LBA was considered to be one of the highest status items attainable, playing an instrumental role in diplomatic gift-giving. When considered with the archaeological information, the significance of these finds at Tall Zirā‛a indicates that this city was a settlement of high status, not primarily a convenient trading stop on the Transjordan route.  相似文献

This article examines the intersections of technology and the exhibition medium by focusing on an individual, the mechanical engineer Robert Runeberg. It makes visible individual involvement in transnational mobility and in large-scale processes of modernization. The article explores how becoming a modern professional was not only connected to formal education and practical training, but also to the capacity to extract and produce knowledge via the exhibition medium. Concurrently, the case discloses essential qualities, such as the cohesion, dynamicity and flexibility of the exhibition medium.  相似文献

The article contributes to the smart specialization literature by presenting a new approach, connectivity analysis, where Triple Helix (TH) relations (involving universities, companies and government) are at the centre of the entrepreneurial discovery process. Relations between helices may be seen, from the point of departure of proximity, as preconditions of connectivity, or interaction, measured through expectations and experiences. This offers potential solution to two limitations of proximity approach: its static nature and narrow focus on dyadic relationships. The connectivity analysis reveals the extent of mutual expectations, as well as tensions, or gaps. Based on this analysis, the article presents a policy model that is used to map structures of networks and gaps between TH actors. It may also identify strengths, weaknesses and problems. This analysis is used as input to structured dialogues between actors in leading positions in the TH and in smart specialization policy-making and implementation. This approach may lead to policy interventions supporting entrepreneurial discoveries. The model has been developed in partnership with researchers and the Regional Council of Ostrobothnia. The article also presents this case study and demonstrates the use of the connectivity model in practice.  相似文献

The Suomussalmi copper adze is a native copper artefact discovered in 1980 on Kukkosaari Island (Suomussalmi, north-eastern Finland). Since then the artefact has been repeatedly used as an example when narrating the introduction of metal technology in prehistoric Finland, while its chronological position, function and significance have remained poorly studied. Here the object is reviewed both through the results of new metallographic analyses and by re-examining its position in the context of early metal use in north-eastern Europe during the Neolithic and the Bronze Age. The results of metallographic analyses indicate that the adze was shaped by melting/casting followed by cold hammering; both techniques are shown to have been used in the research area – Finland and north-west Russia – as early as during the Neolithic. While the provenance of the metal remains to be assigned, possible domestic, Karelian as well as Uralian sources are assayed critically. Instead of plain analyses regarding techno-typology and function, the Suomussalmi adze is here connected to the general enrichment of the (material) world that took place multi-locally through the adoption of new raw materials and the increased interest in their real or presumed properties.  相似文献

This article argues that the Cold War nostalgia of the present in the United States is ultimately based upon a poor – instrumentalist – reading of history. If anything, Cold War nostalgia shows the malleability of our present-day understanding of the past.  相似文献
