A Procedure for the Displacement-Based Seismic Assessment of Infilled RC Frames

The aim of this study was to propose an extension of the displacement-based assessment procedure for infilled reinforced concrete (RC) frames. Two fundamental steps of the displacement-based approach were studied: the determination of the equivalent viscous damping and the definition of the limit-state displacement profile. The proposed criteria were derived by examining the results of two different numerical investigations regarding the nonlinear seismic response of single- and multi-story infilled RC frames. Lastly, the effectiveness of the method was verified through comparisons, in terms of displacement demand, with the results of nonlinear dynamic analyses.     

Average and core silver content of ancient-debased coins via neutron diffraction and specific gravity

The measurement of the fineness of debased ancient silver coins has proven to be a very difficult issue, which has been studied for a long time. In this paper, this subject is analysed, and the various consequences of the silver surface enrichment (SSE) are discussed exploiting the most recent investigations. A new model is proposed for the complex object that is an ancient-debased silver coin, based on the silver profiles measured on some sectioned specimens. The model is applied to a sample of 43 coins, mainly Roman victoriati, Cisalpine and Illyrian drachms (from late III to I century B.C.). The coins are investigated in two different ways: neutron diffraction (ND) and specific gravity (SG). The results of the two measurements are combined via the proposed model to provide a more complete numismatic information of the original fineness of the monetary alloy. As a result, a relation between SSE thickness and SG is derived, which, for these coinages, allows to estimate the original alloy silver content from a simple SG measurement; the same method can be used to study other debased coinages, provided that all the procedure (ND and SG) is applied.     

Sequential Incisions on a Cave Bear Bone from the Middle Paleolithic of Pešturina Cave,Serbia

We present the detailed analysis of a cervical vertebra from a cave bear, found at Pe?turina cave, Serbia, in a Mousterian archaeological level dated by radiocarbon at 43.5–44.6 kyr cal BP, and by ESR to between 93.5 and 102.5 kyr BP. Identified as a portion of the cranial articular facet, the fragment displays ten subparallel grooves. The microscopic study of these grooves and other surface modification present on the bone fragment, conducted with multifocus optical and confocal microscopes and complemented by a taphonomic analysis of the associated faunal assemblage, supports the hypothesis that the incisions were made by humans. Results are used to critically examine ambiguities implicit in the analysis and interpretation of early engravings, a category of material culture that has been playing a key role in the identification of early instances of symbolically mediated behavior.     

From exchange to voice. Voting in southern Italy

The article focuses on the Italian general election held on 4 March 2018, which was notable for the surprising results in southern Italy. These results will be analysed by looking at two dimensions of electoral behaviour: on one hand, participation and volatility, on the other the success of the protest parties, the Five Star Movement (M.5.S.) and the League. These features will be considered in relation to the territorial distribution of the vote. More specifically, in the 2018 election participation was exceptionally high, especially in the south which in some regions saw electors returning to the polls. But electoral volatility is still high. Both factors affected the extraordinary success of new protest parties and collapse of the traditional parties. Traditionally in the south the vote has gone to moderate and pro-government parties, but this time in all constituencies the M.5.S., an ‘eccentric’, protest or populist party-movement, which in many cases took over 40 per cent of the votes, with a peak of 50 per cent in Campania and Sicily. Further, the wave of protest votes favoured another party with no previous support in this geographical area, the League. It may be too soon to say whether these changes in the form and dynamics of the party system are long-lasting and able to achieve a lasting change in the political spectrum, but so far the outcome of election has given a further push to the radicalization of both electoral demand and supply.     

Space Invaders in Barcelona: Political Society and Institutional Invention Beyond Representation

In the contemporary neoliberal urban dynamics, those agencies that are on the margin of society constantly disrupt the boundaries of civil representation and forge new institutional relations within the dynamics of urban governance. I explore how this process was enacted at the turn of the century in Barcelona, looking at two coeval social mobilisations: the lock‐in of undocumented migrants in the Iglesia del Pi (2001), and the project of las agencias at the Museum of Contemporary Arts (1999–2003), both of which unfolded in the central neighbourhood of Raval. The invasion of the boundaries of civil society emerges here as a double phenomenon—one that develops both within society and in relation to institutions, instituting new modes of urban politics.     

Fabio Luca Cavazza,the New Frontier and the opening to the left in Italy

This article focuses on the key role played by Fabio Luca Cavazza, founder of the publishing house Il Mulino, in the development of cultural relations between the US and Italy in the early Cold War by drawing on Cavazza’s personal papers, an as yet unexplored archival source. The Department of State and the Eisenhower administration opposed a government that included the Socialists. However, thanks to the special relationship he had with the ‘New Frontier’s men’, in particular Arthur Schlesinger Jr., Cavazza was able to revive the issue, showing how it was in line with Kennedy’s New Frontier policy.     

Radiocarbon and U-series dating of the endemic deer Praemegaceros cazioti (Depéret) from “Grotta Juntu”, Sardinia

Radiocarbon and U-series methods (²³⁰Th/U and ²³¹Pa/²³⁵U) for absolute age determination have been applied to some fossil samples from Grotta Juntu, in North Eastern Sardinia (Italy). The remains belong to the endemic deer species Praemegaceros cazioti, which is here represented by an almost complete skeleton. The three dating methods lead to concordant ages of about 7500 years BP, indicating that the skeleton was maintained as closed system after burial. Taking into consideration these results, Praemegaceros cazioti from Grotta Juntu is now the youngest representative of this species in Sardinia.     

Middle Stone Age bone tools from the Howiesons Poort layers,Sibudu Cave,South Africa

Recently discovered bone implements from Middle Stone Age (MSA) deposits at Sibudu Cave, South Africa, confirm the existence of a bone tool industry for the Howiesons Poort (HP) technocomplex. Previously, an isolated bone point from Klasies River provided inconclusive evidence. This paper describes three bone tools: two points and the end of a polished spatula-shaped piece, from unequivocal HP layers at Sibudu Cave (with ages greater than ∼61 ka). Comparative microscopic and morphometric analysis of the Sibudu specimens together with bone tools from southern African Middle and Later Stone Age (LSA) deposits, an Iron Age occupation, nineteenth century Bushman hunter-gatherer toolkits, and bone tools used experimentally in a variety of tasks, reveals that the Sibudu polished piece has use-wear reminiscent of that on bones experimentally used to work animal hides. A slender point is consistent with a pin or needle-like implement, while a larger point, reminiscent of the single specimen from Peers Cave, parallels large un-poisoned bone arrow points from LSA, Iron Age and historical Bushman sites. Additional support for the Sibudu point having served as an arrow tip comes from backed lithics in the HP compatible with this use, and the recovery of older, larger bone and lithic points from Blombos Cave, interpreted as spear heads. If the bone point from the HP layers at Sibudu Cave is substantiated by future discoveries, this will push back the origin of bow and bone arrow technology by at least 20,000 years, and corroborate arguments in favour of the hypothesis that crucial technological innovations took place during the MSA in Africa.     

The Abandonment of the ZH-Mozartstrasse Early Bronze Age Lake-settlement. GIS Computer Simulation of the Lake-level Fluctuation Hypothesis

Although 'lake-dwellings' existed from the middle of the fifth millennium to the eighth century BC, the entire phenomenon was not a continuous one. There are several periods when the lake shores were abandoned and subsequently reoccupied. The pattern of occupation depends on cultural as well as environmental factors, amongst them the topography and the climate.
Unlike the southern part of the Alps, which seems to have had a more regular occupational pattern throughout the Neolithic and the Bronze Age, the northern Alpine region shows a marked discontinuity along most of the lake shores. Two relevant breaks in lake-shore occupation are known within the northern Alpine region Bronze Age. The first occurred between the 24th and the 20th centuries BC, and the second from the 15th to the middle of the 12th century BC.
The Early Bronze Age site of ZH-Mozartstrasse, situated on the western extreme of Lake Zurich (Switzerland), was abandoned immediately before the beginning of the second major occupational gap in 1503 BC. Two other Early Bronze Age sites namely Bodman-Schachen 1 on Lake Constance, and Arbon-Bleiche 2 on the Swiss part (the southern shore) of the same lake, follow a similar chronology in occupation; and they were both abandoned in the last decade of the 16th century BC.
A possible cause of abandonment is discussed in this paper using an environmental approach related to an abrupt change of climatic conditions which resulted in an increase of the lake levels which forced those prehistoric populations to leave the proximity of the lake shores. Following the implications of pollen and sedimental analyses, the transformation of the Bronze Age landscape caused by the lake water invasion will be simulated with the help of CAD and GIS computer programs.
