La eclosión de la opinión del alumnado sobre la enseñanza de la Geografía. El geoforo iberoamericano en 2015
2015
Los datos que se aportan en esta síntesis anual nos indican que existe un crecimiento muy relevante no sólo en las visitas sino, sobre todo, en la participación del Geoforo Iberoamericano a través de las opiniones de alumnos y docentes. La didáctica de la Geografía se transforma en educación ciudadana por medio de las redes sociales, una aspiración que se ha gestado desde el año 2009. La colaboración de las personas de un lado y otro del Océano Atlántico nos permitirá definir con más rigor y precisión los desafíos de la formación docente en los próximos años.
Frontières des communautés polarisées : application à l'étude des théories complotistes autour des vaccins
2021
Les données des réseaux sociaux sont de plus en plus utilisées pour en extraire de la valeur, dans des domaines tels que le marketing, la politique ou la sociologie. Celles-ci peuvent être représentées sous forme de graphes, en modélisant précisément les interactions à travers des liens dirigés et pondérés. Dans l'analyse des données des réseaux sociaux, l'étude des communautés est une étape essentielle. Toutefois, pour une interprétation fine des phénomènes, il est également nécessaire d'étudier leurs interactions et de pouvoir détecter des traces de polarisation. Nous proposons une méthode qui permet d'évaluer l'antagonisme des communautés et d'identifier leurs frontières dans des réseaux…
Creative Network Communities in the Translocal Space of Digital Networks
2013
What should sociological research be in the age of Web 2.0? Considering that the task of “network sociology” is not only empirical research but also the interpretation of tendencies of the network culture, this research explores the rise of network communities within Eastern and Western Europe in the early Internet era. I coined the term creative networks to distinguish these early creative and social activities from today’s popular social networking. Thus I aimed to interpret the meaning of social action; the motivation of creative community actors, their main fields of activities and social organization forms; and the potential that these early developments contain for the future sustaina…
Predicting the availability of users' devices in Decentralized Online Social Networks
2018
The understanding of the user temporal behavior is a crucial aspect for all those systems that rely on user resources for daily operations, such as decentralized online social networks (DOSNs). Indeed, DOSNs exploit the devices of their users to take on and share the tasks needed to provide services such as storing the published data. In the last years, the increasing popularity of DOSN services has changed the way of how people interact with each other by enabling users to connect to these services at any time by using their personal devices (such as notebooks or smartphones). As a result, the availability of data in these systems is strongly affected (or reflected) by the temporal behavio…
Beyond good and evil: The impact of digital environment in family life
2019
Internet has changed the way we interact with others and has become an essential tool for daily activities. Children and adolescents are the main users of new digital technologies and their first contact with a screen happens increasingly earlier in life. Its premature use can be dangerous: technology represents a “supernormal stimulus” that can act on the brain reward circuit and affect neural development. In this article we describe the effects of technology on the brain, well-being, social and family relationships, highlighting both positive and negative ones: rather than defining a priori any type of technology as “good” or “bad”, we should consider how specific applications are used in…
Political Identities Constructed on a Social Network: The Labour Party on Facebook Boards
2019
This paper is concerned with how an (institutional) political identity is constructed on a Social Network (SN) wall, which represents the political identity of the party as designed in digital interactive contexts, and where political image constructions are eventually accepted or negotiated by the digital audience. Like other political parties, the Labour Party resorts to online platforms for official accounts and political message dissemination (Gerbaudo 2014; Boyd 2014) and constructs its (online) identity. Since interaction is seen (Baumann 2000; De Fina 2011) as the most important locus for the production of identities, this study looks at Facebook boards as interactional sites where t…
Anagraphical relationships and crime specialization within Cosa Nostra
2021
Abstract The aim of the present work is to investigate the relationships established within Cosa Nostra, by making use of networks and complex-systems methods. The analysis is performed at three different levels, that is, individuals, groups within mafia syndicates, and relationships amongst mafia syndicates. The reported empirical analysis is based on the criminal records of 632 affiliates to Cosa Nostra selected from a set of 125 judgements emitted by the Palermo courts from 2000 to 2014. According to the criminal records of the Palermo Prosecutor Office, such a dataset includes approximately 10% of the whole population of Cosa Nostra affiliates in western Sicily. Furthermore, the vital s…
