La Cosa Queer: saggio introduttivo
No full textIl tentativo di costruire un canone queer non può che essere proposto sotto il segno dell’ironia. Di fatto, nonostante alcuni degli autori e delle autrici che presentiamo abbiano assunto un ruolo quasi eroico nella rappresentazione della teoria queer, e nonostante i testi che presentiamo siano, ciascuno a suo modo, testi-chiave, sappiamo con certezza che questa è la nostra selezione e che ciò ha aggiunto un portato performativo al contenuto espressivo dei testi. Sappiamo che questo effetto è coestensivo a qualunque operazione di reiterazione, e dunque anche a quella forma particolare di reiterazione che va sotto il nome di traduzione culturale
SEDIMENTARY DYNAMICS OF THE MARETTIMO CONTINENTAL SHELF AND MARETTIMO CHANNEL (EGADI ISLANDS – WESTERN MEDITERRANEAN): ANALYSIS OF DEPOSITIONAL AND EROSIONAL FEATURES.
No full textSedimentary dynamics of the Marettimo continental shelf and Marettimo Channel (Egadi Island – Western Mediterranean), have been unveiled based on the erosive and
depositional features observed at the seafloor.
Different morphologic features were recognized through side scan sonar, multibeam and high-resolution seismics, acquired in the framework of national Research Projects
(CARG, GebecSud, MaGIC) carried out by the Department of Earth and Marine Science (former Department of Geology and Geodesy) of the University of Palermo. Sediment
samples have been also collected and analyzed.
The Egadi Islands are part of the NW Sicilian offshore, and belong to the mountain chain that connects the Sicilian chain to the Maghrebides one. The Marettimo Island
represents an isolated portion of the Egadi continental shelf and is separated from the rest of the archipelago by the Marettimo Channel.
Previous studies allowed to recognize different kind of sedimentary structures along the seafloor. Lo Iacono and Guillén (2008) described extensive field of subaqueous dunes
(Ashley, 1990) along the Marettimo inner shelf, forming on gravelly and pebbly sediments and related to strong storm events (H:5.5 m, T: 12 s). Larger dunes have been
observed in the north-western sector of the inner shelf with wavelengths ranging from 1 to 2.5 m, heights between 15 cm and 30 cm and extending laterally for hundreds of
meters. Moreover in the north-eastern sector of the inner shelf, sorted bedforms have been detected at a depth of 40 m: they are characterized by a width varying between
15 m and 50 m and a length that reaches hundreds of meters.
In the south-eastern sector of the Marettimo outer shelf, Colantoni et al. (1993) map two groups of sedimentary structures. In the same area, Lo Iacono (2004) recognized
two-dimensional and three-dimensional subaqueous dunes. 2D dunes are found at depths between 60 and 90 m and show a wavelength variable between 15 and 50 m. 3D
dunes, which are found at a depth of 80 m, are characterized by a wavelength of 30 m and a lateral extent of 50 m.
Morphological evidences of a strong hydrodynamic regime come also from the morphobathymetric analysis of the Marettimo Channel, that is a 24 km long submarine valley
oriented NNW-SSE, with a depth ranging from a minimum of 180 m to a maximum of 370 m and a width from 2 km to 14 km. Inside the channel, south of its narrowest point,
a 180 m deep bathymetric threshold separates two areas, which deepens towards opposite directions: north-west and south. The flanks of the sector that deepens towards
the NW are affected by mass-wasting features (Lo Iacono et al., 2007). The western flank of the channel, which delimits the Marettimo continental shelf, is carved by gullies,
making the shelf-edge very uneven. Gullies develop to a maximum depth of 280 m and have a length of 250 m and a width of 50 m. At the bottom of the channel a linear
incision 20 m deep, 400 m wide and almost 3 km long, is probably generated by erosive bottom currents.
On the whole, the morpho-sedimentary structures here described reveal a strong hydrodynamic regime. The morphological and textural features of the bedforms observed on
the Marettimo inner continental shelf suggest the occurrence of sporadic medium to strong storm events coming from western sectors. The morphological characteristics of
the Marettimo Channel reveal the occurrence of strong bottom currents probably related to the severe interchange of water masses between the Tyrrhenian Sea and the Sicily
Channel.

La bambola di Cagliostro
No full textCommedia parigina par excellence, Coppélia ou la Fille aux yeux d'émail di Arthur Saint-Léon è una creazione promossa dal Théatre de l'Opéra di Parigi, imprescindibile punto di partenza per ricostruzioni o remake (Petipa, Cecchetti, Lacotte, Vikharev). L'inventore della bambola Coppélia è Coppelius, personaggio tratto dal racconto Der Sandmann di E.T.A. Hoffmann già citato nel saggio Das Unheimliche (Freud) e qui analizzato con particolare attenzione ai motivi degli occhi (v. Blade Runner) e dei movimenti perturbanti degli automi (cfr. Kleist)
Submarine canyons of north-western Sicily (Southern Tyrrhenian Sea): Variability in morphology, sedimentary processes and evolution on a tectonically active margin
No full textSwath-bathymetry, mono-channel and multi-channel seismic reflection records acquired during the last two decades on the northern Sicilian margin have unveiled a dense network of submarine canyons within the depth range of 80–2100 m. The canyons display a relevant variability in their geometry, morphology and sedimentary processes. The margin shows a young, tectonically active shelf to slope setting, linking the Sicilian–Maghrebian Thrust Belt to the Tyrrhenian oceanic realm, developed during the Neogene–Quaternary time span. The aim of this study is to highlight the main governing factors that contributed to the evolution and differentiation of the northern Sicilian canyons, mainly focusing on the Gulf of Palermo and on the Gulf of Castellammare. Tectonic control is more evident in the canyons of the Gulf of Palermo, with submarine landslides retrograding on a steep slope and mainly controlling their evolution. Otherwise, canyons, tributaries and gullies mapped in the Gulf of Castellammare developed on a less steep substrate and display sinuous to meandering paths, with a relevant role of coastal/shelf sedimentary inputs and downslope turbidity processes in their formation. Results suggest that, despite the geographically close proximity of the two study areas, the different structural settings of the Castellammare and Palermo Basins are mainly responsible for canyon variability. Data indicate likely on-going uplift and tilting movements along the Sicilian margin, influencing the development of the studied canyons, which have probably been more active during the Quaternary glacial maxima than they are in the present day

«Zuccheide. La technicienne Limido e la tragédienne Zucchi a confronto»
No full textNello specchio della stampa d’epoca (Zuccheide, Napoli 1881) sono ritratte Virginia Zucchi e Giovannina Limido, due rappresentanti della scuola italiana virtuosistica e d’espressione a confronto, due artiste diverse tra loro per destino umano e professionale.
Infine, le fotografie della Zucchi - ritratti in posa e in primo piano in cui l’espressione e il gesto lasciano intravedere una fisionomia e una personalità conformi alle esigenze della recitazione nel cinema muto – sono messe in relazione ai fotogrammi de La fille de l’eau (1924) dedicato da Jean Renoir alla moglie Andrée Heuschling.Two artists, Virginia Zucchi and Giovannina Limido - very different for destiny, career and today fame - are portrayed in the press of the time (Zuccheide, Naples 1881), as highly representative of the Italian ballet school, appreciated for two main aspects: virtuoso performance and expressiveness.
Eventually, the photographs of Zucchi – portraits, close-ups and postures shots so similar to the acting in silent movies - are related to frames of Jean Renoir’s La fille de l'eau (1924), which he dedicated to his wife Andrée Heuschling
