ABSTRACT Border cities or regions are in theory more affected by the EU integration process than more central locations as it more drastically influences their transaction costs and market potential. We find a positive empirical effect of EU enlargement as measured by the growth in population share along the integration borders. This effect is active for a limited distance (70 km) and time period (30 years), and is more important for large cities and regions. Despite this positive EU enlargement effect along the border, a location close to a border remains a burden in view of the (larger) negative general border effect. 相似文献

During the Late Roman and Byzantine period, natron glass was made from its raw materials in a limited number of primary production centres in Egypt and Syro-Palestine. For the earlier Hellenistic and Roman period, no primary furnaces have been found and the location of primary production during this era remains unclear. Ancient authors such as Strabo and Pliny the Elder suggest that glassmaking sands were found near the River Belus (Israel), in Egypt, near the mouth of the Volturno River (Italy) and also in Spain and France. However, primary production in the western part of the Mediterranean is not supported by any direct archaeological evidence and possible sand raw materials from these regions have never been evaluated for their suitability to produce glass. 相似文献

Abstract
Southwest Ethiopia’s cool, moist, and steep highlands differ from other African environments, and may have fostered distinct patterns of Holocene resource use and intensification. Prior to 2004, only a few archaeological projects probed eastern and northern margins of this region. The Kafa Archaeological Project (2004–2006) excavated ten caves and rockshelters in different environments in the heart of southwest Ethiopia to obtain a Holocene chronology and compare it with adjacent regions. At Kumali Rockshelter, middle Holocene deposits show use of a microlithic industry to obtain wild game, and excellent macrobotanical preservation promises to reveal changes in plant use from 4,700 14C bp to the present. Ceramics and domestic animals appear at Kumali and Koka by ~2,000 14C bp, suggesting herding and pottery making appeared late and contacts with neighboring regions were tenuous. Technologically conservative people continued microlith production and sporadic rockshelter use into the eighteenth century CE. 相似文献354.

We report on energy-dispersive X-ray fluorescence (EDXRF) sourcing of 807 basalt artifacts and 34 basalt ecofacts recovered from stratified midden at Nu‘alolo Kai, Kaua‘i. These data are compared with EDXRF analyses of 473 alluvial pebbles from Waimea Canyon, 34 adzes from the Kaua‘i Museum, and published geochemical data for Kaua‘i basalts. Formal tools, such as adzes, chisels, and mirrors were predominantly manufactured from sources not available at Nu‘alolo Kai. Most adzes and chisels are consistent with sources available elsewhere on Kaua‘i, but two basalt mirrors are outside the expected geochemical range of Kaua‘i basalts. In contrast, almost all expedient tools were manufactured from basalts available at Nu‘alolo Kai. These findings support the existence of an island-wide distribution system for adze material on Kaua‘i, and challenges extant models of pre-contact Hawaiian economics to consider the mechanisms through which specialized commodities were produced and distributed. 相似文献

The last major synthesis of the Upper Pleistocene and early Holocene prehistory of the Horn was published over thirty years ago. This paper therefore attempts critically to review the current state of knowledge and research pertaining to Middle Stone Age and Later Stone Age hunter/gatherer culture history and adaptation in the region that now encompasses Somalia, Ethiopia and Djibouti. Although the archaeological record still suffers from major gaps in information, chronometric analyses as well as subsistence, settlement and other behavioural data from stratified excavated sites have begun to reveal the Horn's potential for providing important contributions to understanding late Quaternary hunter/gatherer cultural development.
Résumé Plus de trente ans se sont écoulés depuis la parution de la dernière grande synthèse sur la préhistoire de la Corne de l'Afrique au Pléistocène Supérieur et au début de l'Holocène. Cet article essaie donc de passer en revue de façon critique l'état actuel des connaissances et la recherche sur l'histoire culturelle et sur l'adaptation Middle Stone Age et Later Stone Age dans la région qui comprend la Somalie, l'Ethiopie et le Djibouti. Bien que les documents archéologiques souffrent encore de lacunes majeures en ce qui concerne les informations, les analyses chronométriques et les moyens de subsistance, des données sur les habitations et sur d'autres aspects du comportement obtenus de gisements stratifiés fouillés ont commencé à dévoiler que la Corne pourra éventuellement fournir des contributions importantes à notre compréhension du développement culturel des chasseurs-cueilleurs du Quaternaire final.相似文献

ABSTRACT. Incorporating regional asymmetry and negative feedbacks (congestion) in a model of economic geography and international trade shows that complete specialization of production at one location is unlikely. We identify an agglomerating force: the home market effect, and two spreading forces, competition for demand from immobile sectors of production and congestion. We demonstrate that negative feedbacks can explain the economic viability of small industrial regions observed in the real world. Simulations clarify the basic structure of the model. 相似文献
