Interventions, Productions and Collaborations:the relationship between RAI and visual artists
No full textOn the 17th May 1952, before RAI Radiotelevisione Italiana Studios began their regular broadcast from Milan, the Spatialist painter and sculptor Lucio Fontana broadcast his own experimental ‘artwork’ on Italian television, beginning a fruitful relationship between RAI and visual artists. For some, it provided careers as designers and art directors, such as the painter Mario Sasso and the Arte Povera artist Pino Pascali, while for others, who were given unique access to RAI’s television apparatus, it was an opportunity to explore their own artistic experimentations with an expensive and exclusive medium, such as Carlo Quartucci and Gianni Toti. RAI also hosted seminal artists’ performances on screen including John Cage and Fabio Mauri. This article, based on documents and interviews collected during the Arts and Humanities Research Council funded project REWINDItalia, discusses these and other seminal cases as well as tracing and assessing the history of this fruitful and complex exchange between RAI and visual artists
Maps, lists and classifications: the work of Luca Vitone between image and word on the traces of Joseph Cornell and Georges Perec.
No full textThis article examines the fundamental relationship between word and image in Luca Vitone's artistic research and practice. In particular, it analyses and tries to assess the relationship between images (including photographs and maps) with specific verbal forms as lists, classifications and categories and suggests that these verbal forms in contemporary artworks are employed as artistic techniques that engage with traditional artistic genres (portrait, landscape and genre-painting). Leuzzi traces two fundamental sources of inspiration in Vitone's use of the list and classification: the American artist Joseph Cornell and the Oulipo writer Georges Perec. The author focuses on the role and nature of the relationship between verbal lists and images in some of Vitone's most renown artworks including Wide City (1998), Wider City (2006), Liberi tutti! (1996, 1997, 2008), Nulla da dire solo da essere (2004) and Nel nome del padre (with Cesare Viel, 2001). The full text of this article is in Italian
A Relational Unsupervised Approach to Author Identification
No full textIn the last decades speaking and writing habits have changed.
Many works faced the author identification task by exploiting frequencybased
approaches, numeric techniques or writing style analysis. Following
the last approach we propose a technique for author identification
based on First-Order Logic. Specifically, we translate the complex data
represented by natural language text to complex (relational) patterns
that represent the writing style of an author. Then, we model an author
as the result of clustering the relational descriptions associated to the
sentences. The underlying idea is that such a model can express the typical
way in which an author composes the sentences in his writings. So,
if we can map such writing habits from the unknown-author model to
the known-author model, we can conclude that the author is the same.
Preliminary results are promising and the approach seems viable in real
contexts since it does not need a training phase and performs well also

Dinamica di una corrente costiera interagente con un promontorio: uno studio numerico per un fluido stratificato
No full textA 3-D numerical study of pollutant dispersion in a coastal current interacting with a headland
No full textRepresentation and identity in contemporary women artists' video.
No full textThis essay is an initial study that examines selected contemporary video artworks addressing identity and representation by contemporary Italian women artists. The author shows how these women artists seek to avoid the objectification and sanitisation of the traditional iconographies involving women in patriarchal Catholic systems. Selected works by Elisabetta Di Sopra, Francesca Fini, and Mariateresa Sartori are discussed by comparing elements from works by earlier generations of feminist video artists, such as Pipilotti Rist, Elaine Shemilt, and Catherine Elwes. Drawing on theories of both video and feminist art, this article examines how the development of a new aesthetic in early women's video art practice in the 1970s and 1980s is still relevant to the task of critically examining and assessing aesthetics in video today, and how video remains a key tool used to experiment with the remediation of women's representation and identity
The effect of a promontory on the passive tracer advected by a coastal current: a full three-dimensional study
No full textThe coupling of a community three-dimensional primitive equation model with a three-dimensional Lagrangian dispersion model is used to describe with sufficient accuracy the temporal and spatial evolution of passive tracers released along a coast characterized by the presence of a cape. The simulations show how different initial conditions influence dispersion properties in a stratified sea, also to provide some insight on the valuation of the environmental impact of pollutants released along the coast. Finally, the power spectra content in a well-defined frequency range of the internal gravity waves is interpreted on the basis of vortex shedding in the lee of the promontory
Self/portraits:the Mirror, the Self and the Other. Identity and Representation in Early Women’s Video Art in Europe
No full textIn this chapter, the author discusses how the category of the self-portrait is significant to critically interpret and contextualise many relevant women artists and early video artworks, which engaged in and tried to defy some tropes and topoi of this genre from various perspectives. In this respect, video art became a tool to de-territorialise the genre of self-portraiture, as a means for female artists to actively position themselves in art history and to further challenge the art historical canon in general.
Drawing from theoretical approaches by video, film and feminist authors and art historians as Rosalind Krauss, Laura Mulvey, Catherine Elwes and Marsha Meskimmon, this chapter includes the analysis of case studies by some of the most relevant European women video pioneers including Nan Hoover, Ziva Kraus, Marianne Heske, Elaine Shemilt, Tamara Krikorian, Klara Kuchta, Anna Valeria Borsari and Federica Marangoni
Equilibrium dynamics of spin-glass systems
No full textWe present a critical analysis of the Sompolinsky theory of equilibrium dynamics. By using the spherical 2+p spin-glass model we test the asymptotic static limit of the Sompolinsky solution showing that it fails to yield a thermodynamically stable solution. We then present an alternative formulation, based on the Crisanti, Horner, and Sommers [Z. Phys. B: Condens. Matter 92, 257 (1993)] dynamical solution of the spherical p-spin spin-glass model, reproducing a stable static limit that coincides, in the case of a one step replica symmetry breaking ansatz, with the solution at the dynamic free energy threshold at which the relaxing system gets stuck off equilibrium. We formally extend our analysis to any number of replica symmetry breakings R. In the limit R ->infinity, both formulations lead to the Parisi antiparabolic differential equation. This is the special case, though, where no dynamic blocking threshold occurs. The formulation does not contain the additional order parameter Delta of the Sompolinsky theory
