The Role of Territorial Capital in Local Economic Growth: Evidence from Italy

Territorial capital is defined as the system of territorial assets of economic, cultural, social and environmental nature that ensures the development potential of places. The potential of this concept resides in the recognition of possible interactions between factors of different nature. So far, however, very few studies have focused on the empirical verification of the links between territorial capital and economic growth. This work is devoted to the analysis of the relationship between economic growth and territorial capital in Italian NUTS3 regions between 1999 and 2008. The distribution of territorial assets across regions points out the huge gap between Italian macro-areas. These divergences do not clearly reproduce the differentials in GDP growth. The second part of the analysis is focused on the joint effect of the territorial capital components on the regional economic performance. Our findings emphasize the role of some endogenous factors in explaining the differentiation of regional growth patterns. Moreover, they point out the importance of soft assets in correspondence of an external shock, as the one represented by the recent financial crisis.     

Integrating radar and laser-based remote sensing techniques for monitoring structural deformation of archaeological monuments

Ground-Based Synthetic Aperture Radar Interferometry (GBInSAR) and Terrestrial Laser Scanning (TLS) were purposely integrated to obtain 3D interferometric radar point clouds to facilitate the spatial interpretation of displacements affecting archaeological monuments. The paper describes the procedure to implement this integrated approach in the real-world situations of surveillance of archaeological and built heritage. Targeted tests were carried out on the case study of the Domus Tiberiana sited along the northern side of the Palatino Hill in the central archaeological area of Rome, Italy, and displacements of the monument were monitored over almost one year of acquisition. The GBInSAR – TLS integration provided updated information about the condition of the archaeological structures in relation to their history of instability mechanisms, and did not highlighted a general worsening for the stability of the entire monument. Point-wise and prompt detection of displacement anomalies and/or sudden changes in displacement trends proved the suitability of the method to support early warning procedures, also to evaluate effects on the masonry due to human activities.     

Exploring Nonlinear Spatial Dependence in the Tails

In many instances it is of interest to measure the degree of similarity between neighboring regions. Spatial autocorrelation measures are the most popular means of doing it. However, such measures only capture a global linear relationship between regions, whereas in many circumstances a more general instrument is required. For instance, in economic poverty analysis or environmental applications (and in other cases where we are interested in extreme events and threshold exceedances) we should be more interested in the spatial pattern in the tails of the joint distributions. In this article we introduce some exploratory tool that focuses on the bivariate joint tails behavior to detect a pattern of spatial regularities. The method will be illustrated with reference to simulated environmental data.     

Geophysical investigation of the Temple of Apollo (Hierapolis,Turkey)

The ruins of Hierapolis are located a few kilometres North of Laodicea in the Lycus Valley (western Turkey). This area is characterised by a large geothermic field that produces several hot water springs along tectonic structures (fractures and faults).     

Protocol for lapis lazuli provenance determination: evidence for an Afghan origin of the stones used for ancient carved artefacts kept at the Egyptian Museum of Florence (Italy)

Despite that the Badakhshan Province (Afghanistan) remains the most plausible hypothesis for the lapis lazuli used in antiquity, alternatives proposed in literature are worth to study to confirm or disprove their historical reliability. In this work, a protocol for determining the provenance of lapis lazuli rocks used for carved artefacts is described. Markers for the univocal attribution of the raw material to a source were identified analysing 45 rocks of known provenance (among which 15 georeferenced) from 4 quarry districts. To the best of our knowledge, this reference database is the widest in provenance studies on lapis lazuli. All the markers are recognisable by means of Ion Beam Analysis (IBA) techniques, in particular micro-proton-induced x-ray emission (PIXE) and micro-ionoluminescence (IL). These techniques are non-invasive and applicable in air, allowing to analyse artworks and rocks of practically any shape and dimension without sample preparation.The protocol was applied to determine the provenance of raw material used for carved lapis lazuli artefacts kept at the Egyptian Museum of Florence, the second most important Egyptian museum in Italy, second only to the museum of Turin. The collection in Florence has a great historical value and includes several lapis lazuli pendants, scarabs, small statuettes and amulets ascribable mainly to the first millennium BC. Following the protocol, 11 of these artefacts were analysed by means of IBA techniques. Results ascribe the raw material to the Afghan quarry district.     

CULTURAL IDENTITY AND KNOWLEDGE CREATION IN COSMOPOLITAN CITIES*

ABSTRACT We study how the city system is affected by the possibility for the members of the same cultural diaspora to interact across different cities. In so doing, we propose a simple two‐city model with two mobile cultural groups. A localized externality fosters the productivity of individuals when groups interact in a city. At the same time, such interaction dilutes cultural identities and reduces the consumption of culture‐specific goods and services. We show that the two groups segregate in different cities when diaspora members find it hard to communicate at distance whereas they integrate in multicultural cities when communication is easy. The model generates situations in which segregation is an equilibrium but is Pareto dominated by integration.     

Myths and symbols in the political culture of Catalan nationalism (1880–1914)

Historiography on the phenomenology of nationalisms has often pointed to the importance of myths and symbols in the construction of these political movements, underlining how the past is transfigured and/or particular historical episodes are recast for use in creating a given political discourse in the present. By adopting this viewpoint, the aim of this paper is to analyse the evolution of historiographical thinking on the use of myths and symbols in contemporary politics, giving particular attention to how they were brought to bear in the early days of the Catalan nationalist movement. This initial period, covering the late nineteenth and early twentieth centuries, is of special interest in the case of Catalan nationalism because it was a phase of politicisation marked – much as it was in other nationalist movements across Europe – by a nationalisation of history, a selection of foundation myths and historical milestones, and a crystallisation of the movement's symbols.     

Analysis of rock samples collected from rock hewn churches of Lalibela,Ethiopia using laser-induced breakdown spectroscopy

With the aim to study alteration processes of the rock hewn churches from Lalibela (Ethiopia), we applied Laser Induced Breakdown Spectroscopy (LIBS) technique to measure the elemental composition both of the bulk rock materials and their external layers, exposed to the environmental factors. The analytical plasma was generated by nanosecond pulses of an Nd: YAG laser emitting at 1064 nm. Different major and minor sample constituents were detected, including Ca, Mg, Na, Fe, Ti, Al and K. The detected O emission originates both from air surrounding and the sample, while the intensity of N lines, coming exclusively from air, was used for the LIBS signal normalization. By depth profiling of the weathered basalt rock, we observed a lower presence of K in the external layers, corresponding to the first 5 laser shots. The emission from this element is anti-correlated with the line intensities from O, and this was attributed to the variations in relative abundances of clay minerals and K-feldspar. The analogue measurements were performed on the tuff rock, and compared to the spectra from powder samples containing only the external soft material, scratched from the rocks. These analyses show an abundance of H in the weathered, wetted layers and suggest that cations are lost from the constituent primary minerals and replaced by H⁺; this process disrupts the lattice structure and causes a marked loss of strength. The studies presented here demonstrate that LIBS is a useful technique for studying the alteration processes in the rocks, caused by environmental factors.
