La scheda UG (Scheda di Unità Geoarcheologica). Proposta di un nuovo strumento per la descrizione standardizzata del deposito archeologico
No full textUn grave problema delle schede di registrazione dei dati archeologici, in particolare della “scheda US”, è rappresentato dall’assenza di una struttura comune e di una sintassi ed un dizionario standardizzati. Ciò impedisce la comunicabilità e l’interscambio di dati tra archeologi. La nuova “scheda UG”, basata su criteri geoarcheologici, intende modificare la “scheda US” ed offrire uno strumento per una registrazione completa, oggettiva e standardizzata dei dati di scavo
In the shadow of the church: the building of mosques in early medieval Syria
No full textIn his book In the Shadow of the Church: The Building of Mosques in Early Medieval Syria Mattia Guidetti examines the establishment of Muslim religious architecture within the Christian context in which it first appeared in the Syrian region, contributing to the debate on the transformation of late antique society to a Muslim one. He scrutinizes the slow process of conversion to Islam of the most important town centers by looking at religious places of both communities between the seventh and the eleventh century. The author assesses the relevancy of churches by analyzing the location of mosques and by researching phenomena of transfer of marble material from churches to mosques
Optimizing MRAI on large scale BGP networks: An emulation-based approach
No full textModifying protocols that pertain to global Internet control is extremely challenging, because experimentation is almost impossible and both analytic and simulation models are not detailed and accurate enough to guarantee that changes will not affect negatively the Internet. Federated testbeds like the ones offered by the Fed4FIRE+ project offer a different solution: off-line Internet-scale experiments with thousands of Autonomous Systems (ASs). This work exploits Fed4FIRE+ for a large-scale experimental analysis of Border Gateway Protocol (BGP) convergence time under different hypotheses of Minimum Route Advertisement Interval (MRAI) setting, including an original proposal to improve its management by dynamically setting MRAI based on the topological position of the ASs in relation to the specific route being advertised with the UPDATE messages. MRAI is a timer that regulates the frequency of successive UPDATE messages sent by a BGP router to a specific peer for a given destination. Its large default value significantly slows down convergence after path changes, but its uncoordinated reduction can trigger storms of UPDATE messages, and set off unstable behaviors known as route flapping. The work is based on standard-compliant modifications of the BIRD BGP daemon and shows the tradeoffs between convergence time and signaling overhead with different management techniques

We have previously examined the antiviral activity of resveratrol on the replication of Epstein Barr Virus (EBV), the etiologic agent of infectious mononucleosis and associated with several types of malignancies of epithelial and lymphoid origin.
In a cellular context that allows in vitro EBV activation and lytic cycle progression through mechanisms closely resembling those that in vivo initiate and enable productive infection, we found that RV inhibited EBV lytic genes expression and the production of viral particles in a dose-dependent manner
Does Independence Affect Regulatory Performance? The case of national competition authorities in the European Union
No full textDespite having always been assumed to be true, a relationship between the independence of regulatory agencies and their performance has never been formally tested. This paper aims at verifying whether formal regulatory independence affects the performance of national competition authorities in the EU member states. The author presents and discusses a statistical analysis which shows that greater formal independence leads competition authorities to investigate more cases and to issue more decisions
Caterina Colombini (1304 ca.-1387) o della cugina sedotta. Una ‘ricostruzione’ della figura di Caterina attraverso i testi letterari, in Le vestigia dei gesuati. L’eredità culturale del Colombini e dei suoi seguaci, a cura di I. Gagliardi, Firenze, Firenze University Press, 2020, pp. 57-71 ISBN 978-88-5518-227-0
No full textIn this essay the author demonstrates that it is possible to reconstruct the figure of Caterina Colombini (1340?-1387) – Giovanni Colombini's cousin – through a group of texts: the hagiography of Caterina, the letters sent to her by Giovanni Colombini and, finally, Giovanni's biography written by Feo Belcari. The author divides his text into four parts: the first part analyzes the content of Caterina's hagiography; the second examines the linguistic form of the hagiographic text; in the third, the author analyzes the latent meaning of the window, a symbolic place where Giovanni and Caterina converse on divine topics; in the last part, to conclude, the teachings that Giovanni gives to Catherine and her spiritual daughters – the Gesuate – are analyzed

The album of Mattia De Rossi’s drawings. Projects for the Galleria Colonna ai Santi Apostoli
No full textThe study proposed here on Mattia De Rossi, a pupil of Gian Lorenzo Bernini and his most trusted collaborator, is part of an investigation that the author is doing on the figure of the architect, making use of an obvious investigative tool: his drawings.
In particular, the exceptional discovery of a bound volume of about 200 drawings of Mattia is a resource of great effectiveness for the study of his professional figure. Among the sheets of the collection, those relating to the construction site of the Galleria Colonna in the eponymous palace in Piazza SS. Apostoli in Rome, are presented.
These drawings explain the important contribution of Mattia and the creative process that led him to the definitive version of the central hall of the gallery. The drawings are also the only graphic documents related to the project of the Galleria Colonna, now only partially known through hypothetical reconstructions.
The case of the Palazzo Colonna is similar to other projects included in the volume, which enlighten us on De Rossi's career, and which explain his position in several important Roman buildings of the second half of seventeenth centur
A Choreographic Dialogue with Caribbean Poetry: The Sacredness of the Feminine in Walcott's Omeros (1990)
No full textThe aim of this paper is to show how the poetry and art of Caribbean writer Derek Walcott (1930-2017) tends to manifest and substantiate the desirable cultural transformation promoted by the work of the American anthropologist and scholar Riane Eisler. The recognition and the exaltation of symbols connected to the feminine world stand at the core of Walcott’s masterpiece Omeros. In a creative mutual dialogue between different genres and identities, the Caribbean author materialises Eisler’s attempts to forge a type of society based on a new partnership ethic. In a second perspective, this paper analyses how Walcott’s work opens the path to possible creative interdisciplinary approaches in the world of the arts. In my own contribution, as a professional dancer and choreographer, I have tried to “give voice” through movements to some episodes relating to the feminine included in Omeros
A Female Mystic and Educator in the Medici grand Duchy: Hagiography of the Venerable Leonora Ramirez de Montalvo (1602-1659) from medieval to modern topoi, in «Rivista di Storia e Letteratura religiosa», 2019/2020-a. 55, pp. 229-265 ISSN 0035-6573
No full textThis article aims to take into account the biography of the Venerable Leonora Ramirez de Montalvo (1602-1659) – mystic and educator in Florence of the Medici gran duchy – written by the jesuit father Cosimo de Pazzi. The author look at demonstrate the presence of medieval topoi and, at the same time, the presence of modern topoi. The whole representation has to be read in the frame of the baroque taste, in particular for the presence of the mystical visions
