This paper investigates how small entrepreneurial firms in two peripheral regions developed by entering the oil and gas industry. The paper draws on previous studies related to the establishment of strategic alliances and emerging clusters and contributes to these research streams by examining the disadvantages of peripheral localization and small firm size. We use a longitudinal case study based on primary data consisting of 54 in-depth interviews conducted between 2007 and 2012 to illustrate that when large-scale oil and gas projects enter a peripheral region, oil companies can moderate local firms' disadvantages related to peripheral localization by actively facilitating relationships with established national firms. By facilitating such relationships and maintaining an active moderating role, strategic alliances and emerging cluster structures can arise. A cross-case analysis illustrates that the oil company had a decisive role in one of the two cases in two dimensions: its role as intermediary between local firms and national firms and its role in fostering the development of an emerging cluster structure by stimulating the establishment of new firms through the oil and gas project. In the second case, the oil company was unable to facilitate regional development.  相似文献

Drawing on previous studies related to the evolutionary aspects of regional innovation systems (RIS), this paper examines how an exogenous shock reduced organizational thinness, fragmentation and lock-in and thereby facilitated path creation and RIS emergence in a peripheral region. A longitudinal case study approach, based on primary data from 39 interviews conducted between 2008 and 2012, is used to investigate how a region was affected by the sudden entry and subsequent activity of a multinational oil company. A multi-level analysis illustrates how this exogenous shock facilitated change at the firm, public authority and macro (regional) levels and thus provides a holistic understanding of the complex mechanisms that underlie regional transformation. The analysis illustrates how the entry of the oil company reduced organizational thinness by stimulating the establishment of external firms. The existing regional actors then managed to reduce their organizational lock-in by adapting their skills and resource bases to new knowledge provided through interfirm relationships (reduced fragmentation), and this reduced organizational lock-in and fragmentation ultimately strengthened the industrial structure and further contributed to regional path creation. A number of innovations were observed, and in combination with the “thickened” institutional structure, this represented the means for an emerging RIS.  相似文献

Weathering forms were encountered during field work in a formerly glaciated shield area in Canada that lies within the Labrador‐Ungava sector of the former Laurentide Ice Sheet. The granite and gneissic granite in the study area display features of surface weathering, such as weathering pits, and of deep weathering, such as an exposed weathering front with associated gravelly saprolite and core stones. Most observations were made along the shoreline of the Caniapiscau reservoir, where wave abrasion since the construction of a hydropower dam has lead to recent exposure of bedrock over extensive areas. The saprolite remnants emphasise the importance of weathering processes in shaping of bedrock relief in the area and together with the other weathering forms indicate restricted glacial erosion. The weathering forms are discussed in the context of glacial erosion and preservation mechanisms.  相似文献

A huge and continuously growing pit is about to divide the Swedish mining town of Malmberget into two halves. What once was the town centre is now a 200 metres deep hole, and private homes and key buildings like the old school and the church have had to be demolished or moved. The pit is a human imposed ‘landscape scar’ epitomising the town’s lost golden age of mining, its present situation of decline and uncertain future prospects – despite a recent recovery in the mining industry. Although the pit is decisively present in the local community, it is not articulated as significant, especially not from a heritage perspective. Why is this so? In this article, we examine the pit as a potential cultural tool for heritage processes, and find that it is indeed used by individuals in this respect, but not in collective memorialisation. We conclude that landscape scars definitely can constitute critical cultural tools, although they may not always need to be labelled as belonging to an ‘authorized heritage discourse’. Instead, the potential of the landscape scar is to enhance the amount and recognition of shared memories in the local community.  相似文献

It has earlier been assumed that the tin cover found on certain antique vases has been attached as a thin foil. In this paper it is shown that the metal may simply have been applied by an immersion technique. Before dipping into the tin melt the pottery must be treated with an adhesion promotor. Animal glue which was known as a binder in ancient times has been found to be useful for the surface treatment.  相似文献
