Most prior media use research has assumed that people use information and communication technologies (ICTs) independently of other ICTs, that is, as discrete media. This study uses cross-organizational, in-depth interview data to uncover the important role that ICT sequences play in persuasion, information exchange, and documentation. The primary occasions for sequential ICT use were (a) preparing for meetings, (b) performing daily tasks, and (c) following up to persuade. When people need to follow up initial communication episodes, the overall groupings of ICTs represent two underlying attributes: degree of connection with others and extent of syn-chroneity. These findings support an expanded perspective on media richness theory and information theory by illustrating that ICT sequences can expand cues and channels and provide error-reducing redundancy for equivocal and uncertain tasks.

How do managers perceive and use media? Media richness theory (MRT) appears to provide persuasive answers to this, but does it work when electronic media is used? Surveys of Japanese managers showed that the perceptions of media, including electronic media, did not contradict MRT. But, even so, the use of rich media was found to be influenced more strongly by whether the media was traditional or electronic, with respect to organizational interpretation of its environment. The perception and use of electronic media may not correspond, though they have generally been assumed to do so.

With increasing popularity of telework arrangements especially among knowledge workers, effective knowledge access in the virtual setup is becoming vital to their performance. Despite the imperative, there has been a lack of theoretical and empirical efforts to investigate knowledge accessibility by distributed workers. Our study examines the gap between telework and central work in accessing knowledge with varying levels of tacitness (or implicitness), and in the use of communication media for knowledge exchange. Media theories offered a conceptual foundation for deriving relevant hypotheses. Necessary data were gathered from teleworkers working at companies with a large telework program in Japan. Both survey questionnaire and interviews were mobilized for balanced information gathering. Data analysis shows that, although information richness perception of a medium is largely rational, it is also partially re-structured by non-rationality factors. It also revealed significant discrepancies between telework and central-work in knowledge accessibility and in the patterns of media usage for knowledge access. Implications of the findings are discussed in terms of telework design and telework productivity.

Current research regarding media richness has concluded that richness is an emergent property of the media and its context. The notion that media richness is an emergent property of the environment implies that it should be measured through perceptions as a psychological reaction to the media and its context. Recent studies have suffered from the lack of a standard set of tools by which to measure perceptions of the media. In an effort to provide a valid reliable measurement tool for the perception of media, an instrument was developed and tested extensively in two different studies.

Erwinia amylovora, the causal agent of fire-blight disease in apple and pear trees, was first isolated in South Korea in 2015. Although numerous studies, including omics analyses, have been conducted on other strains of E. amylovora, studies on South Korean isolates remain limited. In this study, we conducted a comparative proteomic analysis of the strain TS3128, cultured in three media representing different growth conditions. Proteins related to virulence, type III secretion system, and amylovoran production, were more abundant under minimal conditions than in rich conditions. Additionally, various proteins associated with energy production, carbohydrate metabolism, cell wall/membrane/envelope biogenesis, and ion uptake were identified under minimal conditions. The strain TS3128 expresses these proteins to survive in harsh environments. These findings contribute to understanding the cellular mechanisms driving its adaptations to different environmental conditions and provide proteome profiles as reference for future studies on the virulence and adaptation mechanisms of South Korean strains.

Previous research has found that media richness is associated with a positive evaluation of a website. An experiment was carried out where participants were instructed to explore a website presenting a popular place: Venice, Italy. Participants were exposed (or not) to street sounds when exploring the website and had the possibility to control (or not) the photography (using a 360° navigation with their mouse) displayed on the website. The results showed that higher evaluation was associated with sounds and mouse control. The Theory of Media Richness was used to explain our results and the managerial implications for tourism were discussed.

This study was undertaken to provide a more complete understanding of how the selection of various media in virtual team settings affects student team coordination. A total of 75 teams of 304 undergraduate participants took part in the study. Participants were asked to complete surveys before and after the project. Findings suggest that well-coordinated teams appeared to have anticipated the usefulness of social networking and richer communication channels earlier in the project than less well-coordinated teams. After engaging in virtual teamwork, team members identified rich and social channels as more effective while finding less rich channels to be less effective.

This paper expands, refines, and explicates media synchronicity theory, originally proposed in a conference proceeding in 1999 (Dennis and Valacich 1999). Media synchronicity theory (MST) focuses on the ability of media to support synchronicity, a shared pattern of coordinated behavior among individuals as they work together. We expand on the original propositions of MST to argue that communication is composed of two primary processes: conveyance and convergence. The familiarity of individuals with the tasks they are performing and with their coworkers will also affect the relative amounts of these two processes. Media synchronicity theory proposes that for conveyance processes, use of media supporting lower synchronicity should result in better communication performance. For convergence processes, use of media supporting higher synchronicity should result in better communication performance. We identify five capabilities of media (symbol sets, parallelism, transmission velocity, rehearsability, and reprocessability) that influence the development of synchronicity and thus the successful performance of conveyance and convergence communication processes. The successful completion of most tasks involving more than one individual requires both conveyance and convergence processes, thus communication performance will be improved when individuals use a variety of media to perform a task, rather than just one medium.

Organizations have been faced with social/economic pressure to utilize IT and to facilitate communication via technological modes. The communications that are dependent on media richness are affected by individual user characteristics. The individual users who participate in group projects must communicate and ultimately can have different performance and cohesion outcomes based on the mode of communication used. Under the media richness theory, a group's cohesion and performance are impacted by technological modes of communication. Additionally, groups often experience varying levels of individual member agreeability, which affect cohesion and performance. This study identifies significant differences between groups, using specific media to communicate cohesion, the change in cohesion, agreeability, and performance.

The knowledge literature suggests that transferring knowledge leads to synergistic cost advantages, better implementation of organizational strategies, and competitive advantage. Organizations are implementing corporate universities to aid in knowledge transfer There is no standardized definition for corporate universities, but rather models that allow organizations to customize them to meet their training needs. Building on recent work of managing the knowledge transfer process (Murray & Peyrefitte, 2007) and on seminal work on media richness theory (Daft & Lengel, 1986), the authors propose that the type of knowledge to be transferred, and the appropriate media to transfer that knowledge, determine the most beneficial generation of corporate university to achieve competitive advantage. The article presents a model and propositions concerning relationships between the type of knowledge to be transferred, appropriate media selection, and generation of corporate university to implement.
