ABSTRACT

The paper aims to contribute to better understanding of entrepreneurial discovery processes and regional industrial growth by examining (1) how different regional contexts affect entrepreneurial discoveries, and (2) how entrepreneurial discoveries support specific types of industrial path development in different regions. The paper includes empirical studies of the formation and growth of three ‘official’ regional clusters supported by Innovation Norway’s programme for immature clusters. The paper argues that entrepreneurial discoveries should be institutionalized (by system level entrepreneurs) to achieve considerable regional industrial effects. In our cases institutionalization occurs through the creation of cluster organizations and development of the knowledge infrastructure.  相似文献

Finland anchors its legal definition of Saaminess in the bedrock of language ability either of oneself or of at least one of one's parents or grandparents. The Saami Nordic Council's Tromsø definition (1980) reech?s the official Finnish Statement (1973). Back in the villages, however, the grass‐roots Saami use other criteria when determining who is Saami, “blood”. This paper discusses the discrepancies between official government as well as ethnic political wing statements as to the components of Saami identity and those of foot‐soldier Saami in villages such as Vuotso, Finnish Lapland.  相似文献

Abstract

Rural areas are facing prospects of marginalization and peripherality in an age of globalization where the attention of governments and media focuses increasingly on the (lack of) competitiveness of urban and metropolitan regions in Europe. Many rural areas have, therefore, searched for ways to improve their position vis-à-vis other localities by mobilizing local resources and employing policy tools that are believed to foster indigenous social and economic development, including place branding. Unsurprisingly, using food as a means to profile rural localities has become widespread, with branding efforts revolving around local food festivals that commodify local cultural resources. The article attempts to illuminate the challenges faced by branding processes in rural areas through a case study of Løgstør, a small rural town in North Jutland, Denmark, which builds its branding efforts around an annual mussel festival. The analysis focuses on the relationship between stakeholders and branding strategies, and in particular aims to uncover the role of the food festival in aggravating or alleviating inherent tensions between different stakeholders and target groups. It is argued that in the case of Løgstør making a food festival pivotal, a signature event for the place branding efforts has been created, which appeals to both external and internal audiences, and that this may hold wider lessons for place-branding initiatives in other small towns across Europe.  相似文献

The general premise for successful archaeological in situ preservation in wetlands is that raising the water table will ‘seal the grave’ by preventing oxygen from reaching the deposit. The present review reveals that this may not be the entire picture, as a change in habitat may introduce new plant species that can damage site stratigraphy and artefacts. However, reviews on the types and degree of damage caused by vegetation to archaeological remains preserved in situ in wetlands have hitherto only been sporadically treated in the literature. Thus, this paper provides an overview of the adverse effects that various plants species have on the preservation status of wetland archaeology.Disturbance, due to growth of roots and rhizomes of the surrounding soil is denoted contextual disturbance, whereas deterioration of archaeological remains per se acts by several root-related factors that may be spatially and temporally concomitant. In waterlogged anoxic environments, deterioration is mainly related to (i) preferential growth of roots/rhizomes due to nutrient uptake and lesser soil resistance, (ii) root etching due to organic acid exudates, (iii) microbial growth due to root release of oxygen and labile organic compounds, and/or (iv) precipitation of hydroxides due to root release of oxygen. For example, roots of some wetland plants, such as marsh horsetail (Equisetum palustre), have been documented to penetrate archaeological artefacts down to c. 2 m in waterlogged anoxic soils. Here, we demonstrate that cultural heritage site management may unintentionally introduce deep-rooted or exudate aggressive plants by invoking change in hydrological conditions. Moreover, the implementation of biomass energy utilization and agricultural root depth optimization on a worldwide basis stresses the need for more research within root and rhizome impact on archaeological remains in wetlands. In conclusion, the worst-case scenario may be in situ deterioration instead of preservation, and one essential threat to archaeological wetland sites is the impact of wetland vegetation.  相似文献
