This paper explores the location strategies of multinational enterprises (MNEs) from emerging countries (EMNEs) in search for regional strategic assets. The analysis is based on a systematic comparison between EMNEs and multinationals from advanced countries (AMNEs) in order to unveil similarities and differences between these two major sources of foreign investment into the regions of the European Union. The empirical results suggest that EMNEs follow a distinctive logic in their location strategies. They are attracted by the availability of technological competences only when their subsidiaries pursue more sophisticated and technology-intensive activities. Conversely, EMNEs share some behavioural similarities with AMNEs in their response to the spatial agglomeration of investments.  相似文献

Ancient iron tie-rods are handcrafted elements with large geometric irregularities, due to production techniques (they are shaped by hammering and linked by hot-forging) and corrosion processes. In common practice, their cross section (that is one of the main parameter to assess their strength) is manually measured on site with a manual caliber. By analyzing a set of detailed three-dimensional (3D) digital surveys of real ancient tie-rods, this study provide an evaluation of the errors made by in-situ manual geometric measurements. In particular, it shows that, in some cases, manual on-site survey is sufficiently reliable and has errors that fall below 10%. Moreover, it shows that when tie-rods have high corrosion levels in hidden zones (typically those close or within the retaining walls) the on-site survey of visible parts only may produce far greater errors that exceed 100%, leading to a strong overestimation of the cross-section of the tie. The ongoing study is a first step toward the definition of correction coefficients to be applied to the on-site manual measurements of ancient tie-rods, with the final aim to improve the reliability of structural analyses.  相似文献

Practices of cultural production within a peripheral urban neighbourhood can contribute to foster the sense of place, community belonging and local collective action. Starting from a critical perspective on the interconnections between cultural practices and urban regeneration, and developing on the concept of place-making, the paper has two main purposes: to investigate the nature of embeddedness of these practices and explore the ways of self-organization of cultural actors and their relationships with public policies. The case study concerns ‘Barriera di Milano’, a large peripheral area in Turin (Italy), formerly one of the most industrialized zones of the city. Over the past few years, and particularly after the real-estate bubble burst of 2007–2008, in Barriera a lively concentration of initiatives of culture has been taking place, redefining the urban and social space. These initiatives seem to be innovative for many reasons: firstly, while demonstrating a peculiar but significant embeddedness in the neighbourhood, they are mostly self-generated; secondly, the institutional assets, the economic self-sufficiency and the low degree of connection among initiatives support new forms of citizenship and place-making based on a ‘not-for-profit entrepreneurship’.  相似文献

The purpose of this paper is to analyse the influence of Ferdinand Gonseth's epistemological and philosophical reflection on Gaston Bachelard. This will be done on at least two levels: on the one hand, on the level of direct quotations of Gonseth's texts and notions made by Bachelard; on the other, on the level of an agreement between the two conceptions concerning some central issues— agreement that lets one suppose an influence of Gonseth on Bachelard or an identity between their views. One concludes recalling the notion of «subjectivité quelconque», suggested to Bachelard by the gonsethean idea of «logique comme physique de l'objet quelconque», and seeking to grasp the differences between Bachelard's notion of «sujet quelconque», and Gonseth's one ofhomo phenomenologicus. One could define Bachelard's and Gonseth's epistemologies as two phenomenologies of the man of science: this is their main common feature.  相似文献

This paper presents the theory of enterprise clusters and industrial districts, and contrasts it with the evidence of two productive agglomerations in the fashion sector in Colombia. The empirical evidence on Bucaramanga and Medellín, that host the largest groups of Colombian textile and clothing producers and exporters, is based on a survey questionnaire, carried out in November–December 1998. The results of the survey confirm the relevance of the Industrial district concept in understanding the recent developments of Colombia's textile and garments industry, and reveal the presence of some dimensions of an enterprise cluster in both Medellín and Bucaramanga, although each with different characteristics. However, both Colombian clusters are characterized by a low degree of firm–level specialization and poorly–developed enterprise networks. This is similar to what has been observed in most enterprise clusters in Latin America, and may clearly hinder the local external economies and collective efficiency. Backward linkages are poor or lacking in both clusters. The strategy prevailing in most enterprises has been the internalization of many stages of the productive process. Forward linkages are much stronger, and the retailers play a crucial role in the commercial phases. However, only Bucaramanga firms have entered global production and marketing networks, whereas Medellín firms are mainly oriented to the national market. Moreover, the two clusters have developed under very different economic policy regimes, and this had had its consequences on the clusters' performance and structure.  相似文献

Coprolites attributable to humans, dated from the Pleistocene–Holocene transition, obtained from the archaeological site Cerro Casa de Piedra, Santa Cruz Province, were examined for parasites. The feces were processed by rehydration and spontaneous sedimentation using conventional parasitic procedures. Helminthic eggs recovered were identified as Trichuris sp., Calodium sp., other capilariids, and ancylostomid (Nematoda), probably Hymenolepis sp. and anoplocephalid (Cestoda); one oocyst attributable to Eimeria macusaniensis (Apicomplexa) was also found. According to the life-cycles and specificity of the parasites found, it is possible to suggest that some species (i.e., E. macusaniensis and Calodium sp.) represent parasites in transit or pseudoparasitism. Paleoparasitological results revealed the existence of an intensive relationship between parasites and humans in the Pleistocene–Holocene transition in Patagonia. Evidence suggests an early association among parasites, rock shelters and hunter–gatherers in the region. It is also postulated that the ancient lifestyles associated with caves and rock shelters were conductive to illness.  相似文献
