An Analysis of the Internal Organization of Facebook Groups

2019

With the rapid development and growth of online social networks (OSNs), researchers have been pushed forward to improve the knowledge of these complex networks by analyzing several aspects, such as the types of social media, the structural properties of the network, or the interaction patterns among users. In particular, a relevant effort has been devoted to the study and identification of cohesive groups of users in OSNs (also referred as communities) because they are the basic building block of each OSN. While several research works on groups in OSNs have mainly focused on identifying the types of groups and the contents created by their members, the analysis of internal organizations of …

The Harvesting Memories Project: Landscape Archaeology in the Castro/Giardinello Valley and Mt. Barraù (Corleone, Palermo)

2018

Il progetto Harvesting Memories è finalizzato allo studio delle interazioni tra dinamiche umane e fattori ecologici che nella lunga durata hanno contribuito alla formazione dei paesaggi rurali. L’area di studio è localizzata tra Corleone e Campofiorito (Palermo) nei pressi delle contrade Castro e Giardinello e lungo le pendici occidentali di Monte Barrù. Questo distretto dell’Alto Belice Corleonese ha rappresentato un asse di collegamento tra la costa meridionale della Sicilia e quella settentrionale fin all’epoca repubblicana con continuità anche nel Medioevo in cui è citato per la prima volta il toponimo Barraù/Barracù, dal nome arabo ra’s e ǧabal bū ‘r-raḫū, nella Jarida di Monreale del …

Cuando la violencia genera identidad. La guerra en Sri Lanka y la diáspora tamil en Sicilia

2011

Sri Lanka, durante las dos últimas décadas, fue el escenario de una prolongada guerra civil entre la mayoría cingalesa budista y la minoría tamil hindú, que ha defendido su independencia. La primera parte de este artículo muestra que no fueron las diferencias de origen étnico-cultural las que llevaron a la guerra, sino las razones políticas y económicas. La guerra civil ha llevado a una radicalización y cristalización de las diferencias étnicas a través de la manipulación del pasado y del papel político del budismo. La guerra provocó la diáspora tamil en todo el mundo, incluyendo también Sicilia. En la segunda parte del artículo, se presentan algunos puntos del trabajo de campo realizado co…

Monetary Policy Rules: From Adam Smith to John Taylor

2012

We describe, through the lenses of history, the intellectual origins of the Taylor rule. The Taylor rule was an important component of the transformation that swept through the monetary policy landascape in a remarkable few years following the abandonment of monetary targeting. In this long paper we provide an original overview of the long-dated debate on rules vs discretion in monetary policy, ever since Adam Smith and the monetary controversies of the XIX century. We then analyse in greater detail the debates in the interwar years (Wicksell, Keynes, Cassel, Simons, Fisher) and the debates in the 1950s and 1960s (Phillips, Friedman, the rational expectation hipothesis) and how these debate…

Plywood Jig—A New Technique for Root Canal Curvature Measurement

2021

The successful outcome of endodontic treatment is dependent on complete cleaning, shaping as well as three dimensional obturation of the root canal system. A conventional radiograph is a two-dimensional replication of a three-dimensional object and does not provide any conclusive evidence for canal curvatures. An accurate knowledge of the tooth anatomy and curvature is essential to avoid procedural errors. 100 freshly extracted human teeth were used in this study. Digital images were obtained using the plywood JIG and Schneider’s technique. These images were analyzed using the VixWin Pro digital image analyzing software (Gendex system). Statistical analysis was done using paired t test. The…

Narrativa dei Caraibi nel nuovo millennio

2020

L’etichetta “Letterature franco-caraibica” utilizzata, per convenzione, dalla critica per indicare unitariamente la produzione letteraria in lingua francese della regione centrale del Continente americano è assai impropria. La regione dei Caraibi abbraccia, infatti, sia alcune delle isole dell’arcipelago delle Piccole Antille (Martinica, Guadalupa), sia l’isola di Haïti, che fa parte delle Grandi Antille, che la Guiana incastonata sulla costa orientale dell’America meridionale. Pur nella diversità dei movimenti ideologici e degli avvenimenti storici che si sono succeduti nella regione, le opere letterarie degli scrittori caraibici francofoni, nel loro insieme, hanno oscillato, e continuano …

The definition "Franco-Caribbean Literature" used by convention from the critique to indicate all the literary production in French of the central region of the American continent is very improper. The Caribbean region includes in fact the islands of Martinique Guadeloupe Haïti and the Guiana. Despite the diversity of ideological movements and historical events that took place in these countries the literary works of the Caribbean writers have fluctuated and continue to oscillate between two tendencies: that of rooting in tradition and that of escape from it. The writers show themselves open to comparison and dialogue with other literary and cultural traditions in order to create a narrative form that corresponds to the many inheritances of those composite populations. Here the cultural syncretism that has been created allows to recognize a common identity in the name of all that the West wanted to extinguish. The common denominator seems to be inverted in the contradictory result of courageous but dangerous encounters of curiosities that can lead to conflicts to exclusions.

L'intonaco Li Vigni nell'architettura del XX secolo a Palermo. Nuove conoscenze e applicazioni diagnostiche per la manutenzione

2013

Il saggio presenta lo studio degli intonaci formulati per imitare le pietre e i marmi naturali che si diffondono in Sicilia all’inizio del XX secolo ed evidenzia che le prime applicazioni e la diffusione delle nuove malte, anche nel resto dell’Italia, risentono delle sperimentazioni condotte in tutta l’Europa. Il contributo riassume i risultati di una rigorosa e capillare ricognizione tra i brevetti conservati presso l’Archivio Centrale dello Stato a Roma inerenti alle malte per il confezionamento dell’intonaco a “finta pietra”, ne analizza i contenuti in modo critico e pone in risalto i contatti culturali con le sperimentazioni dei materiali in atto nell’ambito dei grandi cantieri di resta…

The paper presents the study of the plaster formulated to imitate the natural stones and marbles that are popular in Sicily in the early twentieth century and points out that the first applications and the dissemination of new mortars also in the rest of Italy feels the influence of the experiments conducted throughout Europe . The contribution summarizes the results of a rigorous and thorough reconnaissance of patents kept in the Archivio Centrale dello Stato in Rome relating to mortars for plastering an artificial stone critically analyzes the content and emphasizes cultural contacts with the experiments on large-scale restoration projects in Italy and France in the late nineteenth century. The analysis of the architectural surfaces is developed with instrumental tests: the levels of adhesion of finishing surface are characterized in particular through a campaign of thermographic investigations and diagnosis is drawn to show that the consolidation of the layers and reintegration are interventions to be introduced ​​within the restoration project and maintenance program.Settore ICAR/19 - Restauro

Primo rinvenimento di Juniperus sabina L. sul massiccio del Pollino, Italia meridionale

1992

Viene segnalata per la prima volta la presenza di Juniperus sabina L. sul massiccio del Pollino, dove la specie è stata rinvenuta in habitat rupicolo in due stazioni ricadenti rispettivamente in territorio calabrese e lucano. Le stazioni vengono caratterizzate dal punto di vista floristico ed ecologico.

The presence of Juniperus sabina L. an Eurasian element is recorded from southern Italy where it has been found in two sites on Mt. Pollino. In Italy this species was so far reported only from the Alps and a few localities of central Apennines. Therefore the finding on Mt. Pollino largely widens its distribution southwards in the Italian Peninsula. As regards Europe J. sabina reaches lower latitudes only in southern Spain. The Authors stress the phytogeographical significance of the sites which are characterized from the floristic and ecological viewpoint.Settore BIO/02 - Botanica Sistematica
