American Horror Story e i suoi fan italiani: interazioni e costruzione del discorso on-line
2020
A partire dal concetto sociologico di “audience performativa”, che contraddistingue alcune forme della spettatorialità televisiva contemporanea, in questo contributo prendo in considerazione l’attività di produzione dei fan; in particolare, la produttività testuale e discorsiva, che è spesso riferita alle serie TV. Discuto, poi, il posto dell’horror nella narrazione seriale, traendo spunto da American Horror Story, la serie di successo ideata, nel 2011, da Ryan Murphy e Brad Falchuk. Quindi, attraverso una ricerca empirica di tipo quali-quantitativo, provo a descrivere e spiegare le modalità d’interazione e i discorsi dei fan italiani, iscritti ad una pagina Facebook dedicata alla serie, fa…
Place Attachment and Its Consequence for Landscape-Scale Management and Readiness to Participate: Social Network Complexity in the Post-Soviet Rural …
2019
This paper uses the tripartite place attachment framework to examine six rural parishes across Estonia and Latvia. Existing analyses/frameworks on participatory processes often neglect the complexity of relationships that rural residents have to their local environments. From a qualitative analysis of face-to-face, semi-structured interviews with case study area inhabitants (23 interviews in Estonia and 27 in Latvia), we depict varying degrees of attachment of individuals to each other and to the place in which they live and their readiness to participate in terms of willingness and ability to participate in a landscape-scale management process. Attachment to the local area was strongest wh…
Italian Amateur Pop-Rock Musicians on Facebook: Mixed Methods and New Findings in Music Making Research
2017
This chapter investigates how and why amateur musicians use social networking sites, employing a mixed-methods approach. Attention is focused on four big Italian Facebook communities of pop-rock musicians: drums, bass, guitar, and keyboard players (overall, 2,101 active users), analyzing the relational and textual data extracted from the web. The chapter analyzes the network structures emerging from the interactions among the users. It also identifies and maps the main areas of discussion (sound shaping, studio recording, marketplace, musical references, computer production, and relations) and the latent semantic dimension characterizing Facebook users’ activities, through social network an…
Social network analysis: the use of graph distances to compare artificial and criminal networks
2021
Aim: Italian criminal groups become more and more dangerous spreading their activities into new sectors. A criminal group is made up of networks of hundreds of family gangs which extended their influence across the world, raking in billions from drug trafficking, extortion and money laundering. We focus in particular on the analysis of the social structure of two Sicilian crime families and we used a Social Network Analysis approach to study the social phenomena. Starting from a real criminal network extracted from meetings emerging from the police physical surveillance during 2000s, we here aim to create artificial models that present similar properties. Methods: We use specific tools of s…
La valorizzazione dell’agoralimentare di qualità e lo sviluppo del territorio
2012
Obiettivo dello studio è indagare la capacità di valorizzazione del patrimonio territoriale in alcuni ambienti della Sicilia (ricadenti nelle province Trapani) posti a confronto con un contesto di riferimento, individuato in Toscana (nella provincia di Siena). Questo studio ha indagato entrambe le aree attraverso due approcci complementari: la relazione tra le attività agricole e l’ambiente – con l’applicazione del DPSIR (Driving forces, Pressures, States, Impacts, Responses; Trisorio, 2004) – e il sistema relazionale degli operatori dei comprensori attraverso la SNA (Social Network Analysis). Si sono pertanto indagati gli aspetti relazionali del sistema produttivo del vino Alcamo DOC e del…
Social Network Analysis of Sicilian Mafia Interconnections
2019
In this paper, we focus on the study of Sicilian Mafia organizations through Social Network Analysis. We analyse datasets reflecting two different Mafia Families, based on examinations of digital trails and judicial documents, respectively. The first dataset includes the phone calls logs among suspected individuals. The second one is based on police traces of meeting that have taken place among different types of criminals. Our breakthrough is twofold. First in the method followed to generate these new datasets. Second, in the method used to carry out a quantitative phenomena investigation that are hard to evaluate. Our networks are weighted ones, with each weight catching the frequency of …
Robust link prediction in criminal networks: A case study of the Sicilian Mafia
2020
Abstract Link prediction exercises may prove particularly challenging with noisy and incomplete networks, such as criminal networks. Also, the link prediction effectiveness may vary across different relations within a social group. We address these issues by assessing the performance of different link prediction algorithms on a mafia organization. The analysis relies on an original dataset manually extracted from the judicial documents of operation “Montagna”, conducted by the Italian law enforcement agencies against individuals affiliated with the Sicilian Mafia. To run our analysis, we extracted two networks: one including meetings and one recording telephone calls among suspects, respect…
Riflessività, interazione e rispetto delle norme. Il contributo dei mixed methods tra analisi dei testi e social network analysis
2018
The book, through a special methodological mix that uses text analysis and social network analysis, explores the ways in which people, starting from some elements considered implicit, are able to problematize specific behaviours. People contribute differently to social change or reproduction, by selecting certain aspects of reality and attributing to these aspects power of constraint or facilitation. Starting from the theoretical approach of Margaret Archer, which looks at the reflexivity of social actors as the capacity to develop an internal conversation, which is able to mediate between structure and agency, the book deals with the dynamics that take place when reflexive types converse o…
Redes, complejidad y Arqueología: otra forma de ver el pasado
2018
La ciencia moderna se ha benefi ciado de los intentos del positivismo y neopositivismo por explicar el mundo sensible, que han generando grandes avances en el mundo de la ciencia, pero que han tenido problemas a la hora de plantear una “Teoría del Todo”. Hay que destacar el hecho de que toda explicación de la realidad es siempre un modelo simplifi cado, que se basa en alguna teoría. Durante los años 90, con el fi n de avanzar en la comprensión de la realidad empírica, comenzaron su andadura lo que se conoce co mo Ciencias de la Complejidad. A través de ellas se pretende explicar una serie de fenómenos comúnes a todos los sistemas formados por elementos interrelacionados, que como un conjunt…
Multilayer Network Analysis: The Identification of Key Actors in a Sicilian Mafia Operation
2021
Recently, Social Network Analysis studies have led to an improvement and to a generalization of existing tools to networks with multiple subsystems and layers of connectivity. These kind of networks are usually called multilayer networks. Multilayer networks in which each layer shares at least one node with some other layer in the network are called multiplex networks. Being a multiplex network does not require all nodes to exist on every layer. In this paper, we built a criminal multiplex network which concerns an anti-mafia operation called “Montagna” and it is based on the examination of a pre-trial detention order issued on March 14, 2007 by the judge for preliminary investigations of t…
