The expressive power of process algebras is investigated in a general setting of structural operational semantics. The notion of an eeective operational semantics is introduced and it is observed that no eeective operational semantics for an enumerable language can specify all eeective process graphs up to trace equivalence. A natural class of Plotkin style SOS speciications is identiied, conta...

Work in human-computer interaction seeks to understand creating and maintaining rapport between humans and ECAs. This study examines if humans will report greater rapport when interacting with an agent with an extraversi...
