This paper conceptualizes industrial location, specifically in the form of foreign investment, as a bargaining process to provide a framework within which to examine Iceland's deals with aluminium multinationals between 1961 and 1994. These deals involve one actual and one planned investment in aluminium smelters. Conceptually, it is argued that the interpretation of industrial location as a bargaining process can be readily incorporated within the geography of enterprise tradition by explicitly recognizing that location factors are not given datum but are created by negotiations among parties whose interests may overlap but do not coincide. In this paper, the main parties are the Icelandic government and aluminium multinationals. While both parties were interested in investments in smelters which would ultilize Iceland's power resources, the initial agreement in the 1960s depended on Iceland's acceptance of foreign investment as an appropriate vehicle of development and the ability of the parties to agree on power supply, power rates and taxation, location, and some jurisdictional issues that had not been anticipated. This deal has since been revised although the impact of the obsolescing bargain is not noticeably evident. The Iceland government has brokered another deal with other multinationals although this project has been put on hold due primarily to unforeseen events in the global economy. Still controversial, the actual and potential structure of Iceland's aluminium industry results directly from these bargains. 相似文献

Palaeogeographical reconstructions of Lake Maliq (Korça Basin,Albania) between 14,000 BP and 2000 BP

Since the early 1990s, excavations of a protohistoric lakeside settlement in the Korça basin carried out by a French–Albanian archaeological team have induced geomorphological and palynological studies about the sedimentary records of Lake Maliq. These studies allow us to distinguish a series of centennial-scale high and low lake level events between 4200 and 4000 cal BP (2899–2637 BC/2843–2416 BC) and 2600 cal BP (822–671 BC), probably due to large-scale climate changes (in the Mediterranean basin). In addition, the sediment sequence also gives evidence of a millennial-scale trend of lake level rise. It appears to be an interplay between lake level rises and falls against tectonic subsidence of the basin allowing accommodation space for sediment deposition.The variations of the lake's level and the lake's surface area influenced the development and the abandonment of the nearby lakeside settlements (like the tell of Sovjan). In order to prepare an archaeological survey around the now dried up lake, we made a 3D model of the Holocene deposit from the lake including these lake level results, geomorphological mapping, excavation data, numerous core logs, AMS 14C dating and SRTM DEM data. The GIS model allowed us to propose four palaeogeographical reconstructions of the extension of Lake Maliq: around 14,000 BP, during the Mesolithic (around 9000 BP – 8781–8542 BC), the Early/Middle Bronze Age transition (around 3800 BP – 2310–2042 BC) and the Iron Age (2600 BP – 822–671 BC). A map of the thickness of the sediments above potential archaeological layers is also proposed. 相似文献
