Theory

Constructivist learning theorists such as Vygotsky, Leidner and Jarvenpaa have theorized that the process of expressing knowledge aids its creation and that conversations benefit the refinement of knowledge. Conversational knowledge management software fulfills this purpose because conversations, e.g. questions and answers, become the source of relevant knowledge in the organization.^[15] Conversational technologies are also seen as tools to support both individual knowledge workers and work units.^[16]

Many advocates of Social Software assume, and even actively argue, that users create actual communities. They have adopted the term "online communities" to describe the resulting social structures.

Film theory seeks to develop concise and systematic concepts that apply to the study of film as art. It was started by Ricciotto Canudo's The Birth of the Sixth Art. Formalist film theory, led by Rudolf Arnheim, Béla Balázs, and Siegfried Kracauer, emphasized how film differed from reality, and thus could be considered a valid fine art. André Bazin reacted against this theory by arguing that film's artistic essence lay in its ability to mechanically reproduce reality not in its differences from reality, and this gave rise to realist theory. More recent analysis spurred by Jacques Lacan's psychoanalysis and Ferdinand de Saussure's semiotics among other things has given rise to psychoanalytical film theory, structuralist film theory, feminist film theory and others. On the other hand, critics from the analytical philosophy tradition, influenced by Wittgenstein, try to clarify misconceptions used in theoretical studies and produce analysis of a film's vocabulary and its link to a form of life.
