• From the literary field to reality TV: the perils of downward celebrity migration

  Oliva Rota, Mercè (SAGE Publications, 2020)

  This article explores ‘downward celebrity migration’, that is, when a celebrity enters a field that is less legitimate than their field of origin. It does so by studying the case of Lucía Etxebarria, a Spanish literary ...
• Issues with common assumptions about the camera pipeline, and their impact in HDR imaging from multiple exposures

  Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2019)

• Language background shapes third-party communication expectations in 14-month-old infants

  Colomer, Marc; Sebastián-Gallés, Núria (Elsevier, 2020)
