    • Quantifying echo chamber effects in information spreading over political communication networks 

      Cota, Wesley; Ferreira, Silvio C.; Pastor Satorras, Romualdo; Starnini, Michele (2019-12-09)
      Article
      Accés obert
      Echo chambers in online social networks, in which users prefer to interact only with ideologically-aligned peers, are believed to facilitate misinformation spreading and contribute to radicalize political discourse. In ...
    • Random walks in non-Poissoinan activity driven temporal networks 

      Moinet, Antoine; Starnini, Michele; Pastor Satorras, Romualdo (2019-09-17)
      Article
      Accés obert
      The interest in non-Markovian dynamics within the complex systems community has recently blossomed, due to a new wealth of time-resolved data pointing out the bursty dynamics of many natural and human interactions, manifested ...
    • Random walks on temporal networks 

      Starnini, Michele; Baronchelli, Andrea; Barrat, Alain; Pastor Satorras, Romualdo (2012)
      Article
      Accés obert
      Many natural and artificial networks evolve in time. Nodes and connections appear and disappear at various time scales, and their dynamics has profound consequences for any processes in which they are involved. The first ...
    • Temporal percolation in activity-driven networks 

      Starnini, Michele; Pastor Satorras, Romualdo (2014-03-14)
      Article
      Accés obert
      We study the temporal percolation properties of temporal networks by taking as a representative example the recently proposed activity-driven-network model [N. Perra et al., Sci. Rep. 2, 469 ( 2012)]. Building upon an ...
    • The echo chamber effect on social media 

      Cinelli, Matteo; De Francisci Morales, Gianmarco; Galeazzi, Alessandro; Quattrociocchi, Walter; Starnini, Michele (2021-02-23)
      Article
      Accés obert
      Social media may limit the exposure to diverse perspectives and favor the formation of groups of like-minded users framing and reinforcing a shared narrative, that is, echo chambers. However, the interaction paradigms among ...
    • The interconnected wealth of nations: shock propagation on global trade-investment multiplex networks 

      Starnini, Michele; Boguña Espinal, Marian; Serrano, M.Angels (Nature, 2019-09-11)
      Article
      Accés obert
      The increasing integration of world economies, which organize in complex multilayer networks of interactions, is one of the critical factors for the global propagation of economic crises. We adopt the network science ...
    • Time-varying networks approach to social dynamics : from individual to collective behavior 

      Starnini, Michele (Universitat Politècnica de Catalunya, 2014-10-24)
      Tesi
      Accés obert
      The data revolution experienced by social science has revealed complex patterns of interactions in human dynamics, such as the heterogeneity and burstiness of social contacts. The recently uncovered temporal dimension of ...
    • Topological properties of a time-integrated activity-driven network 

      Starnini, Michele; Pastor Satorras, Romualdo (2013-06)
      Article
      Accés obert
      Here we consider the topological properties of the integrated networks emerging from the activity-driven model, a temporal network model recently proposed to explain the power-law degree distribution empirically observed ...
    • Trends and Characteristics of Emergency Medical Services in Italy: A 5-Years Population-Based Registry Analysis 

      Campagna, Sara; Conti, Andrea; Starnini, Michele; Dalmasso Blanch, Marc; Gianino, Maria Michela; Borraccino, Alberto (2020-12-11)
      Article
      Accés obert
      Background: Emergency Medical Services (EMS) plays a fundamental role in providing good quality healthcare services to citizens, as they are the first responders in distressing situations. Few studies have used available ...
