"Open Discourse is a technical term used in discourse analysis and Sociolinguistics and is commonly contrasted with Closed Discourse. The concept of open and closed discourse is associated with the overlay of open and closed discourse communities and open and closed communication events. Keys to determining whether a discourse is open or closed include access to information, equity of access, open access, quality of discourse and mechanisms and modalities of discourse control: overt, covert, implicit and incidental. As a conceptual filter and cultural construct, ideology is a function and mechanism of discourse control. Channel and signal of a communication event and register of communication together control discourse and therefore, determine the degree of social inclusion and social exclusion and, by extension, the relative efficiency of that communication event. Open and closed discourse operate along a continuum where absolute closure and complete openness are theoretically untenable due to noise in the channel. The nature of the channel, signal, code, replicability, recording, transmissibility, cataloguing, recall or other variable of a communication event and its information control and context of transmission-as-event, impact its relative position along the continuum between open and closed discourse. In all cases, open discourse is assumed to be sustained discourse. Van Dijk (c.2003: p. 357) holds that: \"Although most discourse control is contextual or global, even local details of meaning, form, or style may be controlled, e.g. the details of an answer in class or court, or choice of lexical items or jargon in courtrooms, classrooms or newsrooms (Martin Rojo 1994)."@en . . .
