This paper deals with the origins and functions of the Swedish consular service in Southern Europe between 1720 and 1815. It is argued that establishment of the consular service was a necessary part of the Swedish policy of trade expansion. Consuls acted partly as commission agents of Swedish merchant and shipowners, because Sweden lacked established trading contacts in the area. Partly, consuls had official diplomatic functions, especially in North Africa. The consular service is conceived as an institutional arrangement reducing transaction costs of Swedish agents. This article suggests that reduction in protection costs in particular was a significant competitive advantage of Swedish merchants and shipowners and was due to peace treaties with the Barbary states in North Africa and Sweden's neutrality in the 18th‐century great power conflicts. 相似文献

Chlorozyga, a new genus of Australian Tournaisian (Early Carboniferous) caenogastropod, is proposed and assigned to the Imoglobidae. Chlorozyga has a larval shell like Imogloba from the Early Carboniferous of North America but differs in teleoconch morphology. As in Imogloba, the initial whorl of Chlorozyga is openly coiled, a feature unknown in Mesozoic and Recent caenogastropods. However, Chlorozyga and Imogloba belong to the Caenogastropoda, given their multi-whorled orthostrophic larval shells. 相似文献

A long‐standing debate in archaeology concerns the sources of technological diversification among prehistoric hunter‐gatherers. This includes the study of the emergence and spread of pressure blade technology in Northern Europe during the Early Holocene. Until now, there has been little technological study of lithic collections from the East Baltic region, and our knowledge of the development and spread of this technology in the area is inadequate. This article presents for the first time a technological analysis of lithic assemblages from seven Early and Middle Mesolithic sites in the territory of present‐day Latvia, offering new possibilities for discussing pressure blade technology and research objectives connected with it. Furthermore, variation in elements of this technology is explored in relation to raw‐material characteristics through experimental flint knapping. Finally, the factors influencing diversity in craft traditions, as well as large‐scale communication and shifting spheres of interaction within Northern Europe during the Mesolithic, are discussed. 相似文献
