How Do Pre-existing R&D Activities in a Region Influence the Performance of Cluster Initiatives? The Case of French Competitiveness Clusters

This article explores the diversity of 66 French competitiveness clusters, which were all accredited in 2005 according to the same specifications, by characterizing the initial context in which they emerged and taking a close look at the link between this initial context and their current performance. Since French competitiveness cluster policy is based on state co-funding of R&D projects, we establish a typology based on a multiple component analysis and a hierarchical ascending classification of the R&D potential of the cluster's territory, the respective R&D efforts of companies and academic laboratories, the kinds of actors setting up the cluster and their pre-existing relationships. We then measure the differences among the five classes relating to their clusters' capacity to obtain state funding for their projects. Our results show that initial context can partially explain competitiveness clusters' performance. Competitiveness clusters in territories possessing significant R&D resources, and involving large companies capable of organizing projects, are the most efficient in obtaining state funding. In contrast, competitiveness clusters without prior cooperation experience perform poorly.

Understanding evolution in the Antwerp chemical cluster: the role of regional development strategies

Research on regional economic development increasingly embraces more nuanced perspectives on the evolution of clusters, industries and agglomerations. The extent to which the emergence and decline of clusters can be directed with intentional regional development strategies is, however, a major point of discussion. The article links the cluster life cycle concept to regional development strategies in order to examine the trajectory of Europe’s largest chemical complex in and around the Port of Antwerp (Belgium). This chemical cluster has matured and currently is in a state of stability. Although the cluster did not experience growth over the last decades in terms of new entrants, it did transform internally and maintained its importance as a production centre. Thus, whereas lock-in mechanisms hampered growth, they also prevented the cluster from going into a state of decline. We argue that while regional development strategies stimulated new emerging clusters in the Flemish region, vested interests in the port and associated lock-in mechanisms have resisted such developments in Antwerp. New growth trajectories based on the chemical cluster were therefore difficult to recreate in the Antwerp region.     

A rallying point for different predators: the avian record from a Late Pleistocene sequence of Grotte des Barasses II (Balazuc,Ardèche,France)

The presence of processed birds in the archeological faunal record is considered key to assessing human dietary evolution. Taphonomic studies on birds from sites older than Marine Isotope Stage (MIS) 2 have become relevant in the last few years, leading to the proposal of more complex scenarios of human subsistence. Several works have demonstrated direct evidence of bird consumption by Homo prior to anatomically modern humans in Europe; however, others support the hypothesis of non-anthropogenic bird accumulations. This has led to the necessity of determining what elements or factors cause the human exploitation of birds in some archeological sites before the end of the Pleistocene. The Grotte des Barasses II site is located within this framework. Short-term human occupations have been attested by the presence of lithic tools and processed macrofaunal remains. Additionally, a small assemblage of bird bones has also been recovered. Here, we present a detailed taphonomic study with the aim of exploring possible relationships between these avian taxa and human occupations. Despite the fact that Neanderthals inhabited the cave, avian specimens show damage pointing to different causative agents. Direct evidence (digestion, gnawing) indicates that mammalian carnivores and nocturnal raptors were mainly involved in the accumulation of bird bones. We propose some factors that might determine whether or not small game was exploited in this specific locality and emphasize the importance of such analytical approaches in the general interpretations of the Pleistocene sites.
