Gaining in impacts by leveraging the policy mix: Evidence from the European Cohesion Policy in more developed regions

This paper investigates how the overall impact of the European Cohesion Policy depends on the composition of the regional investment in Hard (infrastructure) and Soft (business and technical support) projects. The study employs a generalized propensity score (GPS) analysis in a multidimensional treatment context. In particular, the two dimensions considered are given by the Hard and Soft investments. The GPS estimation is based on a set of relevant idiosyncratic features of the regions. The second step estimates a dose–response function in a two-dimensional setting. The results confirm the existence of nonlinearities in the effect of different amounts of funds, but more importantly, show a degree of complementarity between Hard and Soft investment and that for policymakers, it is crucial to exploit such features to achieve more significant impact. The EU's more developed regions could have achieved a doubled GDP p.c. growth rate by pursuing a policy mix where Hard investments are reduced in favor of Soft investments. This improvement is comparable to the one obtained by at least doubling the available resources. The findings add to the evidence collected on the impact of the Cohesion Policy, suggesting a shift of the debate from the quantity to the quality of the expenditure pursued under the umbrella of territorial policies.     

The Roman quarries at Antinoopolis (Egypt): development and techniques

The aim of this research was the survey and the study of the many quarries located in the first spurs of the Gebel el-’Adila, close to Antinoopolis (Middle Egypt). These quarries are an excellent opportunity for observation and research concerning the “landscape archives” and preserve traces of man’s activity, representing a real cultural heritage. The paper gives a short geological setting of the area and reports our recent study (2006 onward) on traces, typologies, methods and development of the quarrying activity in the area, focussing on the Roman period. The working traces allowed us to define the working tools used for quarrying, the organisation of the works and of the quarry exploitation, as in the area many remains of the quarry organisation network are extant or recognisable, such as: service posts, sledge-ways, docks.     

Petrographic and geochemical analysis on the provenance of the Middle Bronze and Late Bronze/Early Iron Age ceramics from Didi Gora and Udabno I, Eastern Georgia

We report thin section petrographic and geochemical analysis of a total of 20 Middle Bronze, Late Bronze/Early Iron Age ceramics excavated from Didi Gora and Udabno I located in the Eastern part of the Republic of Georgia and 31 clay samples from eight different regions in the surrounding areas of the sites. The major and trace element compositions of the ceramics and clays were determined using a wavelength dispersive X-ray fluorescence technique. The results indicate that the ceramics were manufactured from local clays in Eastern Georgia, mainly from two local clays without any preference of one of the sources during the Middle Bronze, Late Bronze/Early Iron Age.     

The face of the poet Dante Alighieri reconstructed by virtual modelling and forensic anthropology techniques

This paper describes the multi-disciplinary approach to reconstruct the face of Dante Alighieri (1265–1321). Since Dante's sepulchre will be opened in 2021, the reconstructive process is based on morphological and metric data collected on the poet's cranium during the formal identification of his remains in 1921 by the anthropologist Fabio Frassetto, as well as on the resulting plaster model. Starting from this plaster model and a morphologically compatible reference mandible, since the original mandible was never found, a 3D digital model of the complete skull was obtained by reverse engineering and virtual modelling techniques. The most important aspect in this work was the method of virtual modelling proposed for the ex novo generation of the mandible. The physical model of the skull (cranium + mandible) was then produced by means of a rapid prototyping system. This model was finally used to recreate Dante's face via traditional facial reconstruction techniques currently used in forensic anthropology.     

Salt Effects in Plastered and Unplastered Outdoors Brick Masonry: Quantitative Laser Monitoring of Surface Decay Evolution

In masonry materials, the superficial decay is a widespread problem. Aggressive environmental agents such as moisture and salts trigger the damage by propagating through the material capillary pores. Although several studies have been carried out on salt crystallization and their damaging effects, additional research effort is required to better investigate this phenomenon on real cases and real weathering conditions. To this purpose, testing and monitoring tools capable of following degradation process since the early beginning are necessary. Repeated visual inspections are commonly used to monitor the superficial decay, but this technique is subjective and thus not capable of providing any quantitative information. In this work, an experimental campaign, carried out in Bologna, Italy, is presented. A two-header brick wall, one main face unplastered and one plastered, was stored outdoors and exposed to weathering over two summers. Before the start of the second aging season, moisture and salt capillary rise was simulated by low-concentrated sodium chloride solution (0.1% -wt). The aim was to favor solution evaporation and salt crystallization and to provoke material damage. The degradation process was monitored based on a contactless, rapid and accurate image diagnostic technique. In particular, high-resolution laser scanning by triangulation technique was adopted. Three-dimensional data acquisition was repeated at the end of both seasons. The proposed procedure successfully extracted quantitative information approximately areas of material spalling and detachment even in the initial phases of decay.     

Eine naturwissenschaftliche Forschungsbibliothek des 18. Jahrhunderts: Die Bibliothek der ‚Naturforschenden Gesellschaft’︁ zu Jena

The ?Naturforschende Gesellschaft’?, founded in 1793, proved instrumental for the development of science at the University of Jena around 1800. Its library can be considered as one of its most important facilities provided for research and for the education of students. Since this library has been preserved almost without losses, we can ask whether this library served the purpose of a research library in the newly established field of ?science’?. In consequence, the role of scientific societies and the genesis of specialised libraries in the area of science can be investigated in an exemplary case, with implications for the concept of scientific research around 1800.     

Italian Jews and their ‘political’ reactions to the fascist regime’s anti-Semitic campaign*

ABSTRACT

The article intends to emphasize the political redefinition of Italian Jews in reaction to the fascist aggression and its different answers ‘organized’. Since 1934 there arose strong divisions within Italian Judaism: the real issue of contention, however, did not reside in the attitude towards fascism, but in the judgement on Zionism and postponed a long-standing dynamics. A group of Jews, called ‘bandieristi’ from a magazine called La Nostra Bandiera, on the basis of a ‘fascist’ programme and anti-Zionism, tried to replace the official establishment of the Jewish representatives, the Union Community of Italian Jewish, as a reference to the fascist authorities. The Union was accused by the ‘bandieristi’ of being complicit with international Jewry and Zionism. The confrontation with fascism exasperated the Italian Judaism internal contradictions, putting in long-term dynamic light that preceded fascism and survived the early post-war years.
