The growth strategies of the two largest so-called independent Russian gas producers – Novatek and Rosneft – as well as developments in international markets and changing domestic energy needs have put pressure on the present Russian gas sector model dominated by Gazprom. The three companies are involved in a struggle over export liberalization as well as the conditions in the domestic market. Liquefied natural gas is top priority for Novatek and Rosneft’s main gas focus is on eastern Russia and Asia, but there is still room for considerable tension with Gazprom. The government wants to both improve Russia’s position in export markets and maintain stable domestic supplies, including to socially disadvantaged regions and institutions. Gazprom is insisting that if further access to export markets is granted to the Independents, then they must take greater responsibility for domestic market obligations. On the other hand, the key Independents seem intent on stopping or slowing down their expansion in the domestic market in order to prioritize export sales, and will certainly not take broader domestic supply responsibilities without better access to export markets. The balancing of policies involves strong players on the Russian economic and political scene, all with ties to the Kremlin. 相似文献

The Impact of Agglomeration Economies on Estimated Demand Thresholds: An Extension of Wensley and Stabler 总被引:1,自引:0,他引:1
Central place theory predicts that geographic markets located in rural areas have lower demand thresholds, and, therefore, a higher frequency of business establishments relative to areas that are more proximate to urban centers, other things equal. Wensley and Stabler (1998) confirm this prediction using data on the location and frequency of business activities in rural Saskatchewan. We demonstrate that this relationship may not always hold true depending on the existence and magnitude of agglomeration economies. If average cost differences associated with being located in an urbanized area are sufficiently large, then the relationship between urban proximity and number of establishments may be reversed. We provide evidence of this reversal using 1996 cross-sectional data on hospital services in Texas. 相似文献

Mortoniceratid ammonites of the Eromanga Basin of Queensland, although uncommon, are reviewed and reassessed utilising all known collections. Representatives of this group are restricted to the Allaru Formation and almost all specimens are Goodhallites goodhalli, a well-known species from the English Gault. The Allaru Formation overlies the Toolebuc Formation, widely considered to be an essentially isochronous unit because of its unusual sedimentary and geochemical character. Using G. goodhalli, the middle and upper Allaru Formation can be directly correlated with the early late Albian orbignyi and auritus Subzones of the Mortoniceras inflatum Zone as recognized in the reference ammonite zonation embedded in the standard Cretaceous time scale. Overlapping ranges of G. goodhalli and Labeceras and Myloceras allow these common Austral heteromorph genera to be also confidently assigned a late Albian age in Australia, matching their biostratigraphic occurrence in South Africa. 相似文献

The restructuring of the pulp and paper industry in the European Community is examined. The factors underlying recent restructuring are evaluated in the light of the impending creation of a Single European Market. Two main sets of factors are identified. ‘Pull’ factors relate directly to Europe as a unified market. ‘Push’ factors relate to sources of supply, as well as to markets. 相似文献

Creating photo‐mosaics and plans of submerged archaeological sites quickly, cost‐effectively and, most importantly, to a high level of geometric accuracy remains a huge challenge in underwater archaeology. This paper describes a system that takes geo‐referenced stereo imagery from a diver‐propelled platform and combines it with mapping techniques widely used in the field of robotic science to create high‐resolution 2D photo‐mosaics and detailed 3D textured models of submerged archaeological features. The system was field tested on the submerged Bronze Age town of Pavlopetri off the coast of Laconia, Greece, in 2010. This paper outlines the equipment used, data collection in the field, image processing and visualization methodology. 相似文献

Museums occupy many roles which are influenced by wider circumstances and changing conditions. This study deals with the case of Singapore’s Asian Civilisations Museum and the manner in which it is used to promote nation building in a multi‐ethnic and relatively newly independent state. In addition, it serves a political purpose and acts as an economic resource. The Asian Civilisations Museum illustrates some of the recent trends affecting the museum sector as a whole and also the particular challenges facing such institutions in a country like Singapore with its many distinctive qualities. 相似文献
