Nethnography and Social Network Analysis for Studying Online Social Space
2022
Author's accepted manuscript This chapter contributes to the current methodological debate on digital, internet-based studies in social research. Based upon an introductive analysis of the research's perspectives, trajectories, and stages that have brought the online social spaces into social research, the chapter focuses on the advantages of combining quanti-quali approaches for approaching online complexity. In particular, the authors offer a deep discussion concerning the value, the methodological, and ethical challenges of netnography and social network analysis (SNA) methods for inquiring online social research by proposing a possible emerging methodological framework guiding further e…
Prevention of Violence against Children and Psychosocial Models of Intervention: Network Analysis of an Inter-Institutional Service
2014
This study describes an Italian service, the Inter-institutional Groups Operating against child Abuse and Maltreatment (GOIAM), which specializes in the treatment of child abuse. The GOIAM service is composed of 53 professionals divided into four different categories: social workers, psychologists, child neuropsychiatrists, and psychopedagogists. With the aim of detecting strengths and weaknesses of the operative model adopted by GOIAM, the whole service was analyzed through the application of social network analysis (SNA). The analysis revealed a low-density network, while the study of centrality yielded different distributions of power indicators (degree, closeness, and betweenness): pres…
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…
Graph Comparison and Artificial Models for Simulating Real Criminal Networks
2021
Network Science is an active research field, with numerous applications in areas like computer science, economics, or sociology. Criminal networks, in particular, possess specific topologies which allow them to exhibit strong resilience to disruption. Starting from a dataset related to meetings between members of a Mafia organization which operated in Sicily during 2000s, we here aim to create artificial models with similar properties. To this end, we use specific tools of Social Network Analysis, including network models (Barabási-Albert identified to be the most promising) and metrics which allow us to quantify the similarity between two networks. To the best of our knowledge, the DeltaCo…

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…
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…
A Comparison of Dyadic and Social Network Assessments of Peer Influence.
2021
The present study compares two methods for assessing peer influence: the longitudinal actor–partner interdependence model (L-APIM) and the longitudinal social network analysis (L-SNA) Model. The data were drawn from 1,995 (49% girls and 51% boys) third grade students ( Mage= 9.68 years). From this sample, L-APIM ( n = 206 indistinguishable dyads and n = 187 distinguishable dyads) and L-SNA ( n = 1,024 total network members) subsamples were created. Students completed peer nominations and objective assessments of mathematical reasoning in the spring of the third and fourth grades. Patterns of statistical significance differed across analyses. Stable distinguishable and indistinguishable L-AP…
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…
