Which region to choose for an industrial policy? A research path to highlight restructuring opportunities

Our study explores research avenues that can help policymakers to assess regional capabilities for ‘green’ economic restructuring. After reviewing the relevant literature, and envisioning research paths which consider both market transactions and externalities, we propose possible ways to translate past research findings into novel statistical tools. Our point of departure is the ‘skill relatedness’ among economic sectors in Norway, as inferred from intersectoral labour flows (years 2008–2014). Then, on the basis of the industrial composition in each of the 161 Norwegian labour market areas, candidate regions that could benefit the most from a ‘green’ restructuring policy, aimed at photovoltaics in our empirical example, are brought forward.     

Between the Mediterranean and the Atlantic: nautical iconography in the south‐west Iberian Peninsula

This study presents two new representations of ships, recently found in Casas del Turuñuelo, Spain, and dated to the end of the 5th century BC. They depict river barges, which supports the importance of river navigation in structuring the central Guadiana region in the Tartessian era. The systematization of all known ship iconography found in the area from the Early Iron Age makes it possible to highlight their homogeneity, and their Mediterranean hallmark. This serves to emphasize the interconnectivity that existed in Iberia's south‐west, fostering a process of cultural hybridization of which the vessels were both result and vehicle.     

Millet microremains—an alternative approach to understand cultivation and use of critical crops in Prehistory

The term “millets” is used to identify several genera of grasses (Poaceae), most of which belong to the subfamily Panicoideae. Millets are one of the major food sources in arid and semi-arid areas of the world and they have been important crops in the prehistory of Africa and Eurasia. In this paper, we discuss phytoliths and starch grains from two of the less studied major millets (Pennisetum glaucum and Sorghum bicolor) as well as from some small millet species that are not normally considered of much importance (so-called forgotten millets: Digitaria ciliaris, Echinochloa colona, Echinochloa frumentacea, Brachiaria ramosa, Setaria pumila and Setaria verticillata). The preliminary results of this study on phytolith morphology, both at single and joined (silica skeletons) morphotypes, and starch grains show great potentials for the identification of different genus or species on the basis of microremains.     

A Methodology for the Evaluation of Hygrometric and Mechanical Properties of Consolidated Stones

Several authors agree that stone surface consolidation works should not significantly alter original mechanical and hygrometric properties of the stones in order to avoid differential stress between the consolidated and non-consolidated parts. Specific limitedly destructive methodologies have been developed for assessing the variation in both mechanical and hygrometric properties, but they require preliminary calibration procedures that are very costly to adopt in terms of both time and money. This research study describes an analytical and experimental procedure aimed at obtaining the necessary hygrometric and mechanical characterization of natural and/or artificial stone, before and after consolidation works, by simply assessing the variation in the distribution of the porous structure.     

Thermographic Survey at Hagia Sophia: Main Arches,Pendentives and Tympana

Hagia Sophia is one of the oldest and most complex existing monuments. Many unanswered questions are still open on the historical and constructive evolution of this monument. The boundaries between the different construction phases and the details of the masonry and materials used in the various phases are still not defined with precision.

The thermographic survey, carried out inside the monument, made ??it possible to answer some of these questions by specifying the exact location of the past interventions and the variability of the materials employed allowing a better understanding of the constructive history of the monument. The technique was applied at a great distance and in normal environmental conditions, taking advantage of the high thermal sensitivity of the instrumentation. The results achieved confirm the validity of the technique in the study of ancient buildings.     

The Evolution of Population Distribution on the Iberian Peninsula: A Transnational Approach (1877–2001)

Abstract

Surpassing the national perspective usually adopted, the authors confirmed the existence of a pattern of population distribution common to the whole Iberian Peninsula in the long run. This pattern is clearly associated with geographical factors. These variables seem to have more weight in explaining changes between 1877/78 and 1940 than in the period from 1940 to 2001. The observation of the cross-border region has shown that proximity to the frontier has not generated any distinct pattern of population density on either side of the boundary line. The spatial coherence of the observed phenomena throughout the Peninsula and of its evolution, independent of the border between states, reinforces the importance of geographic factors in their explanation. At the same time, this verification opens up new issues related to the effect of national political and economic policies.
