Evolution of Innovation Policy in Emilia-Romagna and Valencia: Similar Reality,Similar Results?

This paper examines the evolution of regional innovation policy in Emilia-Romagna and Valencia, two regions with similar economic features that implemented close innovation policies in the 1970s and 1980s. We investigate whether their similarities have led to parallel targets, policy tools and governance developments. We show that innovation policy in both regions suffered from the effects of privatization, budget constraints and changes to manufacturing during the 1990s and we highlight the consequences. Although Emilia-Romagna experienced deeper changes to its innovation policy, privatizations and/or the replacement of public funds promoted commercial approaches and induced market failures in both regions. The worst effects of these policies were the implementation of less-risky innovation projects, the shift towards extra-regional projects and markets, and the favouring of large firms.     

Using airborne small-footprint laser scanner data for detection of cultural remains in forests: an experimental study of the effects of pulse density and DTM smoothing

Cultural remains are laborious to register by means of field surveys. Thus, in recent years several trials using remote sensing data to detect cultural remains have been carried out. The most promising remote sensing technique for such purposes is airborne laser scanning (ALS) from which digital terrain models (DTM) that enable visual interpretations of anomalies on the ground are generated. Although it has been documented previously that ALS is a powerful data source for detection of cultural remains, it has not yet been carried out studies that focus on the effects of the point density of the ALS data and properties of the subsequent generation of the DTM on the detection success of cultural remains. Thus, this study aimed at analyzing these effects by letting four experienced archeologists interpret DTMs generated from ALS data with point densities of 1 p m⁻², 5 p m⁻², and 10 p m⁻², each with three different levels of DTM smoothing. The experiment was conducted according to a randomized complete block design and the analyses were carried out using analysis of variance. The results showed that there was a significant improvement in the detection success when the point density was increased from 1 p m⁻² to 5 p m⁻². There were also some improvements when increasing the point density further to 10 p m⁻², but they were less pronounced. Furthermore, the results showed that the DTM smoothing did not have any significant effect on the detection success.     

Regional polarization in the European Union

This paper examines the level and evolution of polarization in regional per capita income in the European Union between 1977 and 1999. In this analysis, non-parametric estimation techniques are combined with the calculation of various polarization measures. The results obtained suggest a decrease in regional polarization in the European context during the period analysed, as a consequence of various factors, at times working in opposite directions. The findings also reveal the existence of discrepancies between the evolution of polarization and regional inequality. Finally, the analysis carried out highlights the importance of the role played by the national component and the spatial dimension in the formation of homogeneous groups of regions linked by similar development levels in the distribution under study.     

The Anthropogenic Use of Firewood During the European Middle Pleistocene: Charcoal Evidence from Levels XIII and XI of Bolomor Cave,Eastern Iberia (230–160 ka)

Human control of fire is a widely debated issue in the field of Palaeolithic archaeology, since it involved significant technological innovations for human subsistence. Although fire evidence has been the subject of intense debate regarding its natural or anthropogenic nature, most authors agree that combustion structures represent the most direct evidence of human control of fire. Wood charcoal fragments from these contexts represent the fuel remains that result from humans’ collection of firewood, which means they can reveal significant behavioural and palaeoenvironmental information relevant to our understanding of Middle Palaeolithic societies. In this work, we present anthracological data derived from combustion structure 2 (level XIII, ca. 230?ka, MIS 7) and combustion structure 4 (level XI, ca. 160?ka, MIS 6) from Bolomor Cave, which are chronologically among the earliest combustion structures found in Europe. The present work discusses how the presence of black pine and / or scots pine in both levels sheds light on the characterisation of the local landscape. Additional analyses focussing on the pre- and post-depositional processes affecting charcoal preservation point to biodegradation patterns. The aim of this work is to provide the first discussion concerning the anthracological data derived from Bolomor Cave in order to contribute to the general debate regarding the use of fire during the European Middle Pleistocene.     

Exploitation of groundwater in the oasis of Masāfī (UAE): A diachronic perspective

In order to understand the role of water resources in the establishment and long-term evolution of settlements investigated by the French Archaeological Mission in the UAE in the oasis of Masāfī, wells and springs of all periods, identified at the surface and in stratified contexts, were mapped and studied thanks to a multidisciplinary approach combining archaeology, geomorphology, geoarchaeology and ethnography. Our study demonstrates that:

• – The Masāfī oasis was located in a specific geological setting entailing the accumulation of groundwater resources at reachable depth.
• – The groundwater resources remained rather stable from the mid-second millennium BC to the second half of the twentieth century AD. In this respect, the apparent abandonment of the oasis during some periods cannot be explained by water depletion.
• – The groundwater resources have decreased sharply since the second half of the twentieth century AD, due to the introduction of new water extraction technologies, motor pumps and then drillings, as a result of the modernisation and industrialisation of UAE economy.

Our study also stresses the importance of well and spring irrigation in the development of the sedentary settlements in south-eastern Arabia, technologies that have often been neglected in the regional archaeological literature in favour of the qanāt.
