By drawing on a large sample of Spanish manufacturing and service sector firms, the changes in firms’ innovation expenditures that have taken place since the onset of the 2008 economic crisis are analysed, as is the relationship between such changes and the location of the company. Special focus is placed on firms in the Basque Country. Compared to other Spanish regions, the Basque Country differs in terms of its fiscal status, its earlier experience of crises, its innovation performance and its greater focus on innovation-related policies. Our results show that the impact of the crisis on firms’ innovation expenditures in the Basque Country has indeed differed from that in comparable Spanish regions. Even after controlling for sectoral differences and for detailed characteristics at the firm level, firms with R&D employment in the Basque Country showed a significantly lower probability of abandoning innovation activities and even a somewhat higher probability of increasing their innovation efforts. This regional effect is especially significant for small and medium-sized enterprises.  相似文献

The reliability-based design of tuned mass damper considering system parameters uncertainties is noteworthy. However, the same is not the case for liquid dampers. The present study deals with the reliability-based design of tuned liquid column dampers under random earthquake considering system parameters uncertainties. Using the conditional second-order information of response quantities, the total probability concept is applied to evaluate the unconditional failure probability which is subsequently used as the objective function to obtain the damping parameters. A numerical study elucidates the effect of system parameters uncertainties on the damper parameters optimization and safety of the structure.  相似文献

To fully understand the local linkages of Foreign Direct Investment (FDI) plants, we argue it would be useful to analyze the outsourcing patterns of such plants in comparison to domestic plants. Consequently, we examined 1031 industrial plants, both domestic and foreign, located in Spain. The FDI plants show patterns similar to those of domestic plants with regard to the level of outsourcing, the incidence of outsourced production on the companies’ total sales and the economic content of outsourcing relationships. Further, our results show that levels of embeddedness in the local and regional economy of FDI plants are not significantly different from domestic plants. However, FDI plants are highly concentrated spatially in the largest industrial agglomerations. For such plants, Barcelona not only seems a preferred site for location but also for contracting manufacturing tasks.  相似文献

This study identifies ‘heritage as practice’ as an alternative to ‘authorized’ heritage engagement. Heritage, in this sense, is perceived as a source of inspiration and creativity rather than just an asset to be preserved. ‘Heritage as practice’ is informed by the conventional identification and evaluation of heritage, coupled with the architectural and artistic instincts, capacities, creativity, and commitment found in the field of architecture, to interpret heritage. We label the work produced out of this practice as ‘creative material’ that is subjected to further re-creation when it is used as a platform for community engagement. We examine the mechanisms of these engagements through an academic experiment in which architecture students were asked to analyze the representations of the local heritage site of Umm el-Jimal, Jordan. We argue that shifting from ‘authorized’ engagement to informed ‘instinctual’ one gives the students a soft authority over heritage. However, it is the capacity to creatively engage with and about heritage, and use this to continuously and creatively interpret heritage, that makes this authority valid and just.  相似文献

This article reviews evidence and arguments linking the networking behaviour of firms with geographic distance, before examining the spatial relationships of electronics firms in the three major electronics centres in Spain. The focus is on the spatial pattern and extent of different types of inter-firm relations. Based on the analysis of 184 surveyed establishments, displaying different ownership and organization characteristics, the results show that while regional linkages are important, significant extra-regional linkages are also maintained by firms in regional clusters. The spatial extent of linkages depends on the mode of relations; arm's length, network and hierarchy relations show different spatial patterns, as do different types of cooperation. The importance of extra-regional linkages also varies with firm- and plant-specific characteristics. Extra-regional linkages are more common among larger and more R&D-intensive firms, firms with greater presence in the rest of the country and firms with more experience of cooperation and more stable relationships.  相似文献

Nabataeans, in constructing their tombs, added many symbols and geometrical forms, plants and animals. Crowsteps, as a geometrical form, are the most common among these symbols. This study investigates the use of the crowsteps motif found frequently on the facades of Nabataean tombs. The primary focus is to replace models of typological explanation for the introduction of crowsteps into the Nabataean rock‐cut facades. The study begins with tracing the origin of the crowsteps motif and the way it was adopted by the Nabataeans to become one of the most significant features in the making of Nabataean architectural vocabularies. It then provides a theoretical framework for explaining the use and meaning of the crowsteps in Nabataean architecture. Thematic analysis of related literature and existing architectural remains allows us to suggest that crowsteps served both sacred and secular purposes. Sacredly, crowsteps were used to connect the deceased with the principal deities through metaphorical representation either as a ‘high place’ or as a ‘throne’. Secularly, crowsteps served basic human needs: representing identity, wealth and social structure. The study also considers that the Nabataean rock‐cut crowsteps activated the dialogue between different cultural traditions and helped in shaping the ideological cult and identity of the Nabataeans.  相似文献
