The interplay between emotion regulation, interpersonal problems and eating symptoms in individuals with obesity: A network analysis study
2023
Introduction: A complex and bidirectional relationship between eating and psychological symptoms in individuals with obesity has been proposed. This study aims to identify the specific processes playing a role in this association, using a data-driven approach. Methods: Two hundred ninety-four adults with obesity, including 106 (36 %) with binge-eating disorder, were consecutively admitted to a specialized public center. They completed self-report questionnaires to assess emotion regulation, interpersonal problems, self-esteem, binge-eating symptoms, and expectancies regarding eating behaviors. To assess the interplay among eating and psychological variables, a network analysis was used. The…
ESCR Review: Citizenship and Politics
2020
This chapter describes the analyses and results for the ESRC Domain of Citizenship and Politics, guided by two main questions: How digital technology impacts on our autonomy, agency, and privacy; Whether and how our understanding of citizenship is evolving in the digital age. It first provides an initial overview of the major insights from the literature review and analysis, the Delphi surveys, and workshop discussions about the relevant range of the concepts of citizenship and politics in a digital age. Over time the literature shows a shift from issues of public sphere and use of the Internet by government and candidates to more focus on political participation and engagement, especially …
A Study of the Bibliometry and Areas of the Research Groups of Archivos de Bronconeumología (2003–2007)
2010
Introduction Scientific cooperation is essential for the advance of biomedical research. Scientists set up informal groups to work together on common issues, who are the main units in the research funding system. Bibliometric and Social Network Analysis methods allow informal groups in scientific papers to be identified and characterised. The objective of the study is to identify research groups in Archivos de Bronconeumologia between 2003 and 2007 period with the aim of characterizing their scientific collaboration patterns and research areas.
Reti mafiose. Cosa nostra e camorra: organizzazioni criminali a confronto
2011
Nella vastissima produzione editoriale sul fenomeno mafioso i gruppi criminali sono stati spesso rappresentati come organizzazioni verticistiche, fortemente centralizzate e gerarchizzate. Si è fatto spesso ricorso alla metafora della piramide, della burocrazia o dell'azienda, evidenziando, in tal modo, la presenza di una netta articolazione interna e di una precisa suddivisione dei ruoli e delle funzioni tra i singoli associati. Pur riconoscendo l'efficacia e la persistente attualità di una simile rappresentazione, questo volume guarda alle organizzazioni criminali da un punto di vista differente, adoperando una prospettiva di analisi di tipo relazionale. Le singole cosche possono essere, i…
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…
