It also allows researchers to explore the nature of discourse between individuals and within ... | Communicative ecology | 0.784409 |
81,888 | A communicative ecology has three layers: social, discursive and technological (Foth & Hearn, 2007). These layers are seen to be intricately entwined and mutually constitutive, rather than discrete, hierarchical or as having unidirectional causal relationships. While it is challenging to consider each layer in isolatio... | Communicative ecology | 0.784409 |
81,889 | Their version of communicative ecology is influenced by members of a workplace engaging in common activities, the length of time over which interaction takes place, whether communication media is synchronous or asynchronous and members' linguistic or cultural background. There is not a single, agreed upon communicative... | Communicative ecology | 0.784409 |
81,890 | In cultural studies of terrorism, White (2003) uses the term to describe the interchange of signs within interacting networks of individuals and collectives. In their study of computer-mediated communication in the workplace, Yates, Orlikowski and Woerner (2003) draw upon Erickson's (2000) work on genre ecologies to su... | Communicative ecology | 0.784409 |
81,891 | From an applied linguistics perspective, McArthur (2005) describes a communicative ecology as embracing the nature and evolution of language, media and communication technologies. He uses the term to discuss the interactions between the world's languages and communication technologies. Wagner (2004) uses the term to re... | Communicative ecology | 0.784409 |
81,892 | Using methods drawn from linguistic anthropology, their research begins with a period of ethnography in which a rich understanding of the local communicative ecology is formed. Discourse is then analysed in relation to this ecological context (Gumperz, 1999). Roberts (2005) describes a communicative ecology as comprisi... | Communicative ecology | 0.784409 |
81,893 | Shepherd, Arnold, Bellamy and Gibbs (2007) extended the concept to attend to the material and spatial aspects of the communicative ecology of the domestic sphere. The term "communicative ecology" has also been used in other studies with various interpretations. Interactional sociolinguists use the term to describe the ... | Communicative ecology | 0.784409 |
81,894 | In this issue, Allison (2007) looked at the communicative ecology from the perspective of the individual, whereas Wilkin, Ball-Rokeach, Matsaganis and Cheong (2007) used a panoptic perspective to compare the ecologies of geo-ethnic communities. Peeples and Mitchell (2007) used the model to explore the social activity o... | Communicative ecology | 0.784409 |
81,895 | Button and Partridge (2007) used the model to examine the online communicative ecology of neighbourhood websites. The model has also been used to investigate how students communicate and reflect on their learning (Berry & Hamilton, 2006). A special issue of the Electronic Journal of Communication showcased the versatil... | Communicative ecology | 0.784409 |
81,896 | Some studies have reported on the use of a particular ICT, for example community radio (Tacchi, 2005c) or mobile phones (Horst & Miller, 2006;Miller, 2007), in relation to broader communication patterns. More recently, the communicative ecology framework has been extended in studies of the nature of media use to suppor... | Communicative ecology | 0.784409 |
81,897 | He is particularly interested in the relationship between social activities and technologies for surveillance and control. The communicative ecology concept has been further developed for use in studies of information and communication technologies (ICT) initiatives in developing nations (Slater, Tacchi & Lewis, 2002).... | Communicative ecology | 0.784409 |
81,898 | The concept of communicative ecology is derived from Altheide's "ecology of communication" (1994;1995). Altheide developed this concept to examine the mutually influential relationships between information technology, communication formats and social activities, within the context of people's social and physical enviro... | Communicative ecology | 0.784409 |
81,899 | Consequently, if a new communication technology does not complement or enhance the existing toolset it risks rejection. The communicative ecology model allows researchers to examine how a new form of media or technology may or may not be integrated into existing communication patterns (Tacchi, 2006). However, the poten... | Communicative ecology | 0.784409 |
