Success Conditions for Urban Networks: Eurocities and Sister Cities

The present paper investigates the role of urban networks in interaction and integration of cities by means of the “sister city” movement. The paper addresses the relationships of “Eurocities” with their “sister cities” to highlight the main factors behind the successful relationships. The data and information used for evaluation are based on the extensive survey questionnaires filled out by relevant departments or experts of municipalities in Eurocities. A logistic regression method is deployed to identify the most important factors in the success of sister city relationships. The results of our study show that the existence of any former relation with the sister cities affects the success of the relationship positively. This former relation makes it easier to have a future relation with an economic partnership while shortening the process and accelerating the economic partnership. The results also show that two factors, viz. similarities in urban problems and contributions of Eurocities to their sister cities stimulate the willingness of Eurocities to improve the relationship. The contributions as well as economic benefits provided from the sister city relationship and new business and investment opportunities have emerged as the most important factors in sister city relationship.     

Guaranteeing the Protection of Submerged Archaeological Sites Regardless of their Location: The UNESCO Convention on the Protection of the Underwater Cultural Heritage (2001)

The UNESCO 2001 Convention on the Protection of the Underwater Cultural Heritage represents a significant move forward in the global protection and management of underwater cultural heritage. This paper reviews the Convention’s most basic tenets, such as in situ preservation, refusing commercial recovery, encouraging the cooperation of States also beyond territorial waters, and the creation of international standards for underwater archaeology. It also discusses the Scientific and Technical Advisory Body and highlights the Convention’s current status as an important tool to preserve and protect an international maritime heritage.     

New insights into the ancient silver production of the Wallis area, Switzerland

This paper discusses the results of a study of the exploitation history of the metallogenic region of the Wallis, Switzerland. Periods of exploitation in this mining district are determined by comparisons of the lead isotope fingerprint of the mines with those of dated artefacts presumed to have a local origin based on the style of craftsmanship. The approach is based on the study of silver mines in the Wallis area and illustrated by three examples of local craftsmanship: (1) silver jewellery from the Late Iron Age, (2) a reliquary shrine from the Early Middle Ages and (3) silver coins from the Late Middle Age.     

Deciphering bone depositional sequences in caves through the study of manganese coatings

The presence of black-coloured bones in caves has been sometimes associated to the use of fire by humans, but more frequently the agent responsible for black colour is the natural deposition of manganese oxides. Manganese coatings were not usually studied once human action was discarded. However, they can provide valuable information about the origin and the sequence of formation of a palaeontological or archaeological deposit. In this paper, we present a quantitative and qualitative study of the manganese coatings that affect most of the bones recovered in the palaeontological site of Liñares cave (NW of Iberian Peninsula) together with other taphonomic marks. The manganese coatings are superimposed on other features previously existing on the surface of the bones. In turn, the coatings can be affected by other agents that modified them totally or partially. The combined interpretation of the different taphonomic marks provides us with valuable information on the sequence where the different taphonomic processes were produced, as for example the intervention of carnivores in the disarticulation of some elements before the burial, the preservation of anatomic connections until after the burial of the carcasses, and the existence of reworking processes in some parts of the infill.     

Les techniques dans l'espace public

In this article, we intend to study the cultural transformations fostered by the commercialisation of inventions, a major process in the growth of markets and consumption in the XVIII^th century. Inventors' commercial strategies were based on intense mediatisation, combining visual languages (public shows, experiments, exhibitions) and print resources: advertisements, posters, tracts, how-to leaflets and users' books. Technical information and useful knowledge played a major part in the building of markets for inventions. This demension has seldom been stressed neither by historians of consumption nor by historians of technology. Yet, this literature that aimed to emancipate consumers and to develop their participative talents as m means to convince them to buy, expressed the success of knowledge in action, of operative sciences, based on gestures and verbs, on purposive action and projects. Whereas technological science (technologie) in the Enlightenment developed in treatises and dictionaries, it was also stemming from useful literature and commercial ephemeras that allowed appropriations.     

Do industrial districts influence export performance and export intensity? Evidence for Spanish SMEs' internationalization process

This paper seeks to enhance the understanding of the role of the industrial districts in the internationalization process of small and medium-sized enterprises (SMEs). The study focuses essentially upon the following issue: Can the location inside industrial districts influence the export performance and export intensity of the Spanish SMEs? To address this question, this study draws upon a sample of 285 manufacturing firms located in the Valencian community (a Spanish region) surveyed during the period January 2000 to March 2000. It is shown that industrial district location, marketing differentiation, institutional networks, clients' networks, competitors' networks and global orientation of sector and company have a clear influence on firms export performance and export intensity. The results are basically consistent with the limited previous research.
