DC4CD
2017
In this article, we present Distributed Computing for Constrained Devices (DC4CD), a novel software architecture that supports symbolic distributed computing on wireless sensor networks. DC4CD integrates the functionalities of a high-level symbolic interpreter, a compiler, and an operating system, and includes networking abstractions to exchange high-level symbolic code among peer devices. Contrarily to other architectures proposed in the literature, DC4CD allows for changes at runtime, even on deployed nodes of both application and system code. Experimental results show that DC4CD is more efficient in terms of memory usage than existing architectures, with which it also compares well in te…
Development of an IoT Environmental Monitoring Application with a Novel Middleware for Resource Constrained Devices
2014
In this paper the development of a Mobile Health monitoring system is described. The system combines user location data with air quality information provided by a heterogeneous sensing infrastructure providing users with advises about their daily exposure to air pollutants. The highly dynamic integration of different kind of nodes, mostly characterized by rather constrained resources, of this application is crucial to implement the Internet of Things vision, and requires powerful and effective programming methodologies to abstract implementation of high-level distributed processing from hardware dependencies. We then describe our programming methodology and our novel middleware supporting d…
Within the symbolic world of the prehistoric hunters: A GIS-based and 3D model analysis of sites with complexes of linear incisions in western Sicily
2021
Abstract The prehistoric peopling of Sicily has left scattered traces of symbolic activities through well-known rock art expressions in caves and rock shelters located all around the island (among the most significant, the sites of Addaura, Racchio and Genovese). A peculiar phenomenon is the incision of linear signs, often grouped on the same rocky walls, hidden in fissures or placed at the entrance of the underground chambers of caves. In this report, we investigate a sample of these graphic expressions from a spatial and technical point of view. A GIS-based approach presents the territorial pattern providing insight, on a macroscale, into the intentional positioning of the sign complexes.…
La simbologia del potere nella comunicazione diplomatica: i doni di Cambise al re degli Etiopi macrobioi
2010
Language acquired great importance in ancient diplomacy. The success or failure of a diplomatic mission depended greatly upon the ambassador’s skills of persuasion, a product of the efficacy of his words and their suitability to his audience. The ambassador had to be able to choose the most appropriate words to reach the objectives of his mission. The measure of his competence was his capacity to recognize the position of his listener, without undervaluing ideas, preconceptions, and potential reactions. Nevertheless, in certain cases, an ambassador’s ethnographic knowledge of the context where he had to operate determined the successful outcome of a mission. Such knowledge manifested itself…
The Eighteenth-century Opera and the Search for a Meeting Point between Music and Declamation
2019
The article is the result of some researches about the ideas on the operatic reform appeared in Italy and France from 1740s onwards. On the basis of acting, some treatises written by actors, philosophers and musicographers claim the dramatic superiority of recitativo secco or obbligato, and the beauty of aria parlante. (e.g., L. Riccoboni, Dell’arte rappresentativa, 1728, G. Manfredi, L’attore in scena, 1734, G. R. Carli, L’indole del teatro tragico, 1746, and Osservazioni sulla musica antica e moderna, 1744-1786, G. Tartini, Trattato di musica secondo la vera scienza dell’armonia, 1754, F. Algarotti, Saggio sopra l’opera in musica, 1755). Owing to its particular speaking tone linked to dec…
Il tarantismo in Sicilia
2017
Il testo prende in esame il complesso di materiali editi e inediti (fonti storiche e archivistiche, documenti musicali, testimonianze etnografiche) che attestano la presenza del tarantismo in Sicilia dalla metà del Seicento alla fine dell’Ottocento. Il caso siciliano viene quindi inquadrato nell’ambito dell’ampia letteratura che ruota intorno al fenomeno, a partire dal classico studio di Ernesto De Martino fino al dibattito sull’interpretazione del fenomeno fra i poli dell’esorcismo e della possessione, dovuto soprattutto all’etnomusicologo francese Gilber Rouget. L’analisi viene quindi estesa alla tradizione dei guaritori dei morsi di serpenti (i ciaràuli), che con il tarantismo condividon…
Gli occhi, il fuoco, il grano. Simboli, pratiche e credenze tradizionali nel culto di santa Lucia di Siracusa
2020
The folkloric traditions related to Saint Lucia of Syracuse are characterized, in Sicily as well as elsewhere in Italy, by a peculiar mythical-ritual symbolism. The eyes, fire, wheat are the main elements. The Saint is invoked to solve the problems of sight and all ophthalmic pathologies (both in a cult context and in a magical-medical one) and as such she is the recipient of ex voto objects and the protagonist of prayers and spells. On the eve of her dies natalis, bonfires are lit and processions of torches take place; for her festival, celebrated in some centers with solemn functions and processions, foods based on wheat seeds, sometimes added with other legumes, are widely prepared. This…
Continuità, risorgenze, invenzioni? Sui simboli “preistorici” nel folklore contemporaneo
2015
I temi delle continuità culturali e delle “sopravvivenze” sono stati, nel recente passato, al centro del dibattito in ambito antropologico e storico religioso. Ritornano oggi d’attualità in relazione alla questione della patrimonializzazione dei beni immateriali, delle feste religiose “tradizionali” innanzitutto. Gli interrogativi che emergono sia circa l’utilità delle fonti storiche (archeologiche e documentali) ai fini della comprensione della realtà rituale contemporanea, sia rispetto al tema delle continuità cronologiche di pratiche e credenze, meritano infatti, dinanzi alla ormai avvenuta dissoluzione di quella che è stata definita “civiltà contadina” e ai rinnovati interessi verso il …
"Memorie dal sottosuolo". Una prospettiva di indagine sul simbolismo rituale delle feste religiose "tradizionali"
2017
In 1945, writing about the procession of Our Lady of Viggiano, Carlo Levi presents us a peasant world characterized by archaic beliefs and ritual practices, another world « where seasons run on peasant fatigue, [...] like three thousand years before Christ », a world « veiled with black veils, fiery and earthly [...] which you do not enter without a key of magic ». If that other world of the peasants seems to have come to an end today, the beliefs, practices and ritual symbols of reputed “pre-Christian” precedence or in any case alien to the official liturgy, as witnessed by Levi and many other narrators and demoanthropologists from the 19th and 20th century are not, however, definitively l…
Rappresentazioni e territorio nelle dinamiche del turismo: il caso della Lonely Planet Sicily
2018
L’attuale dibattito sul riordino territoriale del Paese rende nuovamente centrale il concetto di territorio che, da sempre, in una prospettiva geografica pone problemi definitori. Esso può essere, infatti, oggetto di produzioni simboliche e (ri)semantizzazioni in grado di ridefinirlo e di creare specifiche modalità di interazione. A questo proposito, il presente lavoro intende proporre una riflessione su alcune dinamiche di produzione e riproduzione simbolica che interessano il concetto di territorio nel turismo, ambito in cui si può osservare una relazione diretta tra rappresentazione del territorio (intesa anche come narrazione) e possibilità d’azione. In particolare, attraverso il caso s…
