Endangered minority and regional languages (‘dialects’) in Italy

The Italian linguistic situation is characterised by a remarkable number of language varieties, although the development of Italian in the past 150 years has been the cause of a language shift from local languages to Italian. The degree of endangerment suffered by so-called ‘Italian dialects’ is shown using the Major Evaluative Factors of Language Vitality drawn up by a UNESCO ad hoc expert group in 2003, and the data offered by the 2006 ISTAT survey on language use. The debate in Italy on the vitality of ‘dialects’ and their future has done little to activate mechanisms and strategies to reverse the worrying language shift that both minority languages and ‘dialects’ are undergoing.     

Myths and the political use of religion in Christian Democratic culture

Abstract

In this essay, the author will attempt to analyze the overall relationship established between the party of Christian Democracy (so named for its affiliation with a traditional religion) and the phenomena of the sacralization of politics that have so profoundly shaped the character of mass parties in the twentieth century. The quest for consensus led the Catholic party to adopt a new language, based on mythical thinking and profoundly indebted – in content and mode of communication – to the experiences of totalitarianism. The active rivalry with political religions marked, both in the phase of development and in the process of communication, the forms of mass political expression of Christian Democracy. De Gasperi's proposal concerning the definition of new identities and political affiliations, both on the national level and on the broader Western level (both in European and Atlantic terms) was the product of a unique ideological development in keeping with the requirements of modern mass politics.     

Confidence Factor?

Eurocode 8 Part 3 (EC8-3) is devoted to assessment and retrofitting of existing buildings. In order to take into account the uncertainty in the knowledge of structural properties, EC8-3 defines, analogously to the ordinary material partial factors, an adjustment factor, called “confidence factor (CF),” whose value depends on the level of knowledge (KL) of properties such as geometry, reinforcement layout and detailing, and materials. This solution is plausible from a logical point of view but it cannot yet profit from the experience of its use in practice, hence it needs to be substantiated by a higher level probabilistic analysis accounting for and propagating epistemic uncertainty (i.e., incomplete knowledge of a structure) throughout the seismic assessment procedure. This article investigates the soundness of the format proposed in EC8-3. The approach taken rests on the simulation of the entire assessment procedure and the evaluation of the distribution of the assessment results (distance from the limit state of interest) conditional on the acquired knowledge. Based on this distribution, a criterion is employed to calibrate the CF values. The obtained values are then critically examined and compared with code-specified ones. The results pinpoint a number of deficiencies that appear to somewhat invalidate the approach. The methodological significance of the work extends beyond the assessment procedure in EC8-3, since similar factors appear in other international guidelines (e.g., the knowledge factor of FEMA356).     

On the Design of Viscous Dampers for the Rehabilitation of Plan-Asymmetric Buildings

In this article, one of the procedures proposed in literature for the design of viscous dampers to be inserted in existing buildings is examined and extended to 3D eccentric buildings. The proposed procedure has been verified through a case study characterized by a six-story RC building. Both plan-symmetric and plan-asymmetric configurations have been considered for comparisons. The effect of considering the plan-asymmetry in the design has been studied. Moreover, also the importance of considering the higher modes has been investigated. The effectiveness of the design procedure has been then evaluated through the comparison with nonlinear dynamic analyses.     

Experimental Characterization of Ancient Metal Tie-Rods in Historic Masonry Buildings

Metal tie-rods play a decisive role in the control of horizontal thrusts in historic masonry buildings. The main goal of the present study is to investigate the relationship between metallurgical and mechanical properties of original tie-rods in order to contribute to a wider study on ancient building stability and their restoration protocols. This article presents the results of an experimental test campaign carried out on 14 historic tie-rods (dating back from 16^th–19^th century) recovered from restoration works or building demolitions. Stress-strain mechanical tests showed that the elastic modulus of the material is comparable to that of modern structural steel, while the strength and the elongation capability are significantly lower, with a large scatter. Further analyses based on metallography allowed us to assess that this mechanical behavior depends on the heterogeneous nature of the material, which can eventually be compared to a composite with vitreous elongated particles in a ferritic or ferrito-pearlitic matrix. The origin of such metallurgical condition is related to the iron making based on direct smelting from ores.     

A study by thermal treatment and X-ray powder diffraction on burnt fragmented bones from tombs II,IV and IX belonging to the hypogeic necropolis of “Sa Figu” near Ittiri,Sassari (Sardinia,Italy)

In the course of an anthropological investigation of three tombs of the hypogeic necropolis of “Sa Figu” (near the village of Ittiri in North Sardinia, Italy), numerous burnt bone fragments were collected. In particular, from the whole necropolis we selected a tenth of long bones from tomb IV, a small fragment of femur from tomb II and four fragments belonging to tomb IX. The aim of this work is to determine a temperature range to which the bone fragments were heated, in order to assess a funerary cremation which was presumably used at that time to quickly and hygienically eliminate the flashy parts of deceased people rather than a purification rite with fires inside the sepulchres. We attempted to evaluate the range of temperature to which the bones were likely subjected, making a joint use of thermal treatment and powder X-ray diffraction investigations. From our X-ray line broadening results carried out with a modern approach (Rietveld method), it emerged that a group of five fragmented burnt bones (one specimen belonging to tomb IV, the other four from tomb IX) were subjected to a heat treatment in a temperature range from 600 and 750 °C. Conversely another group of bones (belonging to tombs II and IV) turned out to be subjected to temperatures not higher than 250 °C.     

Archaeometric evidences of the 4th–2nd century BC amphorae productions in north eastern Sicily

This work focuses on the petro-archaeometric analysis of several transport amphorae dated back from 4th to 2nd century BC which were found in various archaeological excavations recently carried out in Messina and Milazzo (north eastern Sicily). These amphorae, generally known as Graeco-Italic, raise the problem of the identification of their production areas. Petrographic analyses proved the presence of two groups characterised by the presence of coarse metamorphic or volcanic inclusions and one group with finer metamorphic inclusions. Multivariate statistical analyses made it possible to detect the production area of the amphorae with metamorphic inclusion in north eastern Sicily, comparing them with locally produced bricks and clay sediments cropping out near the ancient cities. On the contrary, the studied amphorae rich in volcanic inclusions have petrographic and chemical features which can be attributed to production areas in the Campanian region.     

Questioning Polycentric Development and its Effects. Issues of Definition and Measurement for the Italian NUTS-2 Regions

Polycentric development is a widely used term both in academic research and in the normative agenda. However, its theoretical foundations and economic implications are still unclear and the concept of polycentricity still does not have a shared definition or a shared measurement method. The aim of this study is two-fold. First, it defines and measures polycentricity at a NUTS-2 regional level, by comparing functional and morphological methods. Second, in the light of the role assigned to polycentric development in terms of policy, the study investigates the relationships between the degree of regional polycentricity and the key economic variables of performance, namely, competitiveness, social cohesion and environmental sustainability. Our main finding was that functional and morphological methods lead to similar results. In addition, we find a correlation between polycentricity and a more unequal income distribution and a higher level of productivity, especially when polycentricity was measured in functional terms. No stable correlations were found between polycentricity and measures of environmental sustainability, such as land consumption and greenhouse gas emissions.
