摘要	Media richness analysis applies Daft and Lengel's media richness theory to evaluate communication channels by their capacity to carry rich information and to assess how well a channel fits the equivocality of the task at hand. Rooted in organizational communication, it provides criteria — feedback immediacy, multiplicity of cues, language variety, and personal focus — for ranking channels from lean (a memo) to rich (face-to-face) and for diagnosing whether managers and teams are matching channel to message appropriately.	Intercoder reliability is the degree to which independent coders, applying the same coding scheme to the same content, arrive at the same coding decisions. In content analysis it is the central guarantee that findings reflect the messages rather than the idiosyncrasies of who happened to code them, and reporting a chance-corrected reliability coefficient is a near-universal requirement for publication in communication research.	Manifest content analysis is a quantitative research technique that systematically counts the explicit, surface-level features of communication messages — words, sources, themes, images, or actors that are directly visible in the text or media artifact — according to a predefined coding scheme. Rooted in Bernard Berelson's classic definition of content analysis as the 'objective, systematic, and quantitative description of the manifest content of communication,' it is one of the foundational empirical methods of mass communication and media research.
