Census material representing the tax‐paying segments of the population of the Russian Empire can be used as an empirical basis for carrying out local research in the field of ethno‐social history. This article deals with ethno‐social characteristics of the Ter Sami of the Kola Peninsula, and is based on archival data from a local census report from 1858. Special attention is given to family structure, marriage preferences and the distribution of family names.  相似文献

R&D and innovation increasingly take place in networks that extend beyond the boundaries of a single firm, with customers in an important role in the learning processes involved. This phenomenon is captured by the term “open innovation”. Advantages of open innovation encompass cost reduction and an increased competitiveness. Spatial innovation theory however indicates that the potential of open innovation is not the same for all urban regions, there may be differences between large metropolitan areas and small cities. In this context, the authors compare university spin-off firms in two contrasting urban regions in Europe, Delft in the Netherlands and Trondheim in Norway (a metropolitan area versus an isolated city) with regard to the profile of their learning networks and the contribution of these networks to growth. Learning networks appear to differ in structure and strength, in spatial configuration and also in the influence on job growth. Thus, networks in Delft (in a large metropolitan area) tend to be stronger compared to those in Trondheim (isolated city), whereas the influence of network strength on growth tends to be negative in Delft but positive in Trondheim. Overall, firms in Trondheim tend to rely more on own resources and capabilities and less on learning networks in open innovation.  相似文献

A metallurgical study of platinum plating on a gold pendant of the La Tolita culture of northern Ecuador was carried out, using high‐magnification examination by scanning electron microscopy with analytical facilities. The plating layer was found to comprise a 25 µm thick foil of platinum grains sintered with a gold–silver alloy. The high silver content of this alloy suggests the deliberate selection of pale‐coloured, silver‐rich alluvial gold. The foil had been bonded on to the pre‐formed gold sheet by hammering and heating. It is postulated that a strip of gold sheet was plated by this method and that several pendants were cut from it.  相似文献

The ‘pollen washes’ technique, based on the analysis of the pollen embedded in the porous surface of archaeological artefacts, is developed for investigating past plant usage and consumption and to characterize the functionality of artefacts related to plant processing, gathering and storage. The research presented results in relevant methodological improvements of this technique, which has never previously been applied on materials from European contexts. The improvements allow: (1) faster analysis of a broad series of artefacts or those with large use‐surface areas likely to retain more pollen; and (2) a more thorough, deeper and precise cleaning method, allowing the study of smoother artefacts. Finally, the recovery of Trifolium‐group pollen from a macro‐lithic tool from Xicotó rock shelter (Montsec ranges, Spain) demonstrates that the pollen washes technique can reveal new insights into both the use and consumption of wild and domestic plants by prehistoric societies, and the functionality of archaeological objects whose interpretation is still problematic.  相似文献

This article presents results of a multi-proxy study of a fen deposit in the former mining district of Falkenstein near Schwaz in the Tyrol, Austria. The aim of the study in the framework of the special research program HiMAT (The History of Mining Activities in the Tyrol and Adjacent Areas – Impact on Environment & Human Societies) was to disclose the ecological impact of mining in pollen and heavy metal diagrams and to create a model combining the changes in palaeoecological proxies with historical evidences for mining. The application of this palaeoecological–historical model to prehistoric times allowed us to reconstruct the impact of mining and metallurgic activities in the surroundings of the fen during the last millennia. The results of stratigraphy, radiocarbon dating, LOI, pollen and micro-charcoal analyses as well as geochemical analyses of scandium, lead and lead isotopes validated by historical and archaeological data are hereby presented.  相似文献

The aim of this paper was to determine what technical gestures must be learned in order to produce stone tools. To identify these gestures, we compared the performance of expert knappers and complete novices. We hypothesised that the differences between novices and experts would indicate which technical gestures experts had learned to successfully produce stone tools. Participants were video recorded while attempting to produce a crude handaxe. The recordings were analysed according to ethological methods used to study animal and human behaviour. The knapping performance of each participant was segmented and scored into units in order to identify the technical gestures being used. The results showed considerable differences between experts and novices in three technical gestures: the type of percussion support, the position of the blank and the angle of blow. Therefore, these three technical gestures appear to be crucial in learning to knap stone at the level of bifacial stone toolmakers. By studying how modern knappers gradually master these three technical gestures we may begin to understand how stone knapping is acquired, how bifacial stone tools emerged and what cognitive challenges early handaxe makers had to face.  相似文献

Routine sand dredging for alluvial diamonds at Oranjemund on the southern coast of Namibia exposed remnants of a long forgotten Portuguese merchant ship believed to have wrecked in the 1530s. The rescue excavations yielded over 40 tons of cargo consisting of thousands of gold and silver coins, tons of copper and lead ingots, and large quantities of ivory together with food refuse, part of personal possessions and the superstructure of the ship. This paper discusses the cargo from the shipwreck. The varying provenances show that overland inter-and intra-regional networks fed into the maritime trade between Europe and the Indian sub-continent. As such, the wreck is a lens through which we can view what was happening on the seas as well as on land. Finally we consider wider issues raised by this discovery relating to the protection and management of such material wherever it may be found in future.  相似文献
