Street(icono)clashes. Blu vs. Genus Bononiae: un caso di iconoclastia urbana
No full textMoving from a perspective of semiotics of culture, the article investigates the events which accompanied Banksy and Co: Art in the Urban Form, the exhibition held in the City Museum of Bologna in May 2016, with a special attention to the reaction of the street artist Blu, who decided to erase all his street artworks in the city of Bologna. "Museum discourse" and "street discourse" are analyzed in a comparative and contrastive perspective, with the aim of understanding the interactions between different "discursive spaces" of the city in relation to diverse valorizations of the expressions of urban creativity
What remains of Yugoslavia? From the geopolitical space of Yugoslavia to the virtual space of the Web Yugosphere
No full textThe article works from the double hypothesis that: (1) a Yugoslav socio-cultural space still exists in spite of the dissolution of the former Socialist Federal Republic of Yugoslavia; (2) the communities ‘occupying’ this space can be considered, in some measure, ‘diasporic’, if the ‘Yugoslav diaspora’ is defined by not only the geographic displacement of people but also by the loosening of the connections between the members of an ex-nation who still consider themselves a national community. The ‘space’ mapped in the essay is the so-called ‘virtual space’ of the Web, including all websites that reconnect to the ‘cultural languages’ of the ‘past-country’. The author observes how these ‘different Yugoslavias’ are ‘staged’ and linked together on the Web, and verifies how some far-flung communities rally around the ‘virtual re-foundation’ and ‘virtual representations’ of Yugoslavia. The corpus is constituted mainly of ‘yugonostalgic’ websites that are subjected to a content analysis. The 191 websites of the corpus and the hyper-textual map of their edges are analysed using semantic features together with other tools of categorization
Geotectonic Significance of the Metabasites of the Kinzigitic Series, Ivrea-Verbano Zone (Western Italian Alps)
No full textGeochemical investigations have been carried out on the metabasites of the Ivrea-Verbano Zone (NW-Italy). The Ivrea-Verbano Zone is commonly considered to be a section through the lower continental crust. It is constituted by a steeply dipping sequence of metamorphic rocks (Kinzigitic Series), intruded by a mafic-ultramafic complex. The metabasites of the Kinzigitic Series have a meta-igneous origin, Their protoliths show tholeiilic affinity in the NW and central part of the zone and alkali affinity in the SE. This fact together with the rock associations suggests that a variation of the paleogeographic environment from NW to SE occurs in the Ivrea-Verbano Zone
Forme di vita / forme del corpo: studi di caso.
No full textLa nozione di “forma di vita”, in semiotica, appare al tempo stesso evidente e confusa. Vagliata e discussa da parecchi anni, viene utilizzata da molti studiosi in più occasioni e con diversi scopi. Funziona come un tipico termine ombrello. Parallelamente, molti nodi problematici relativi alla scienza della significazione, pur avendo palesi tangenze con tale nozione, sembrano volerne o poterne fare a meno, dichiarandola in contumacia fuori corso.The notion of "life form", in semiotics, appears at the same time evident and confused. Sieved and discussed for several years, it is used by many scholars on several occasions and for different purposes. It works like a typical umbrella term. At the same time, many problematic questions relating to the science of signification, despite having obvious links with this notion, seem to want or be able to do without it, declaring it in absentia out of course

Fare memoria durante una pandemia. Spazi e corpi simulati nelle pratiche di commemorazione durante il lockdown
No full textThis paper seeks to provide an investigation of the use of memory spaces and the practice of commemoration during the first wave of the Covid-19 pandemic, when people were forced to stay at home due to the lockdown. In particular, the authors point out how the reconfiguration of urban and domestic spaces, together with the increasing use of electronic and technological devices, has contributed to the production of new forms of memorial gathering, in which the collective subject has taken on different semiotic configurations each time. All the case studies in this article are related to a specific memorial day: the Italian commemoration of the 25th April, the date of Nazi-fascist liberation in 1945
Pre-emptive Memories. Anticipating narratives of Covid-19 in practices of commemoration
No full textThis article explores the narratives of the Covid-19 crisis in Italy, in the ways that they intersect with cultural memory processes. Moving from the hypotheses that the Covid-19 crisis, in Italy, has undergone two distinct narrative phases, we focus on the comparison between the forms taken, during the first lockdown, by an important (but also somehow divisive) memory ritual: the celebration of April 25 (the day that Italy was liberated from Nazi-Fascism) and the newly established commemorations of Covid-19 casualties. The aim is to observe the osmoses between two discursive domains (memory discourse vs. emergency discourse). To do so, we propose the concept of ‘pre-emptive memory’, which can be defined as an act of – unwitting – anticipation, pre-figuration and re-combination of the future cultural memory of an ongoing event in the present
TUFFACEOUS DEPOSITS IN THE SEDIMENTARY COVER OF THE STRONA-CENERI ZONE AND IN THE VILLAFORTUNA-TRECATE OIL SYSTEM: PETROLOGICAL, GEOCHEMICAL AND GEOCHRONOLOGICAL CHARACTERIZATION
No full textIn the western sector of the Southern Alps, tuffaceous levels are occasionally found in Triassic sedimentary sequences and the age of the related magmatism is still matter of debate. The few available geochronological data on these tuffites (M. San Giorgio area, Lugano, CH) yield Triassic ages (245±1 Ma; U-Pb zircon [1]), which are slightly older than the stratigraphic position. The precise definition of the tuffite age is, however, important for the Triassic evolution of the western Alps. In particular, if the magmatism is synchronous with their stratigraphic position, tuffites might be linked to the Triassic magmatism documented by the Finero area (NE Ivrea-Verbano Zone [2]). However, it cannot be presently excluded that they are the product of erosion and re-deposition of the Permian acid volcanics located at the base of the Mesozoic sedimentary cover [3].In this work, we have considered the tuffaceous deposits occurring within a late Anisian-Ladinian succession in the Mesozoic sedimentary cover of the Strona-Ceneri Zone in the Borgosesia area [3,4] and the tuffites at the same stratigraphic position found in some wells of the Villafortuna-Trecate oil system field (western Po Plain, Piedmont region, NW Italy) [5]. These tuffaceous deposits are constituted by a variable mixture of magmatic and sedimentary components. Available chamical data on the magmatic component suggests a calc-alkaline affinity. Zircons have been separated with conventional methods from four samples, mounted in epoxy resin and characterised under cathodoluminescence (CL). Based on colour, morphology and internal structure, zircons have been divided in two populations. One group is constituted by light-pink coloured zircons with prismatic habits and tight osciscillatory zoning suggesting growth under magmatic conditions. Zircons from the second group are colourless, rounded in shape and with only relics of magmatic zoning. They most likely suffered metamorphic recrystallization.Ongoing ELA-ICP-MS characterizations of both trace elements composition and U-Pb age of these zircons is expected to provide valuable constraints on the geodynamic evolution of the Southern Alps Domain in Permo-Triassic times.References.
