   Sammanfattning : A large amount of the information in conversations come from non-verbal cues such as facial expressions and body gesture. These cues are lost when we don't communicate face-to-face. But face-to-face communication doesn't have to happen in person. With video communication we can at least deliver information about the facial mimic and some gestures. LÄS MER

7. 5. For every word has its own shadow: Sunsets, Notes From Underground, Waves

   Författare :Lisa Tan; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; affect; becoming; Maurice Blanchot; displacement; dispossession; essay film; experimental video; geological time; liminal; Clarice Lispector; materialism; primordial obscurity; provisional; solitude; Susan Sontag; threshold; transformation; translation; video; video installation; Virginia Woolf;

   Sammanfattning : Liminality permeates this doctoral project's questions: how can an experience of the liminal exist as an artwork? What things and experiences can orient us towards affectivity and states of becoming? Lisa Tan relates such concerns to Clarice Lispector whose writing renders becoming(s) visible. Coupled with Maurice Blanchot and his literary discourse on dispossession and the outside (analogous to becoming), Tan's inquiry is critically engaged inside a moving image practice. LÄS MER
