In our discussion of dysfluency, we specifically avoided the use of the word â€˜errorâ€™. In the past, because written grammar was used to judge speech, common features of speech were judged as errors because they do not occur in the more planned environment of written text.

Thus what type of data is analysed is crucial to what the grammatical findings are. We said earlier that grammar descriptions were increasingly being developed on the basis of examining how language is really used.

Sharing information in business is itself a risky business. The information that is exchanged between b2b partners, for instance, may include order information, customer details and strategic documents. Such information could be priceless to outsiders.

Some commentators criticise the very idea of the â€˜therapy cultureâ€™. The issue for them is not how to get people more involved with their health and the therapeutic relationship, but the unhealthy attitude many people have towards seeking perfect health in the first place. How healthy is it for people to constantly turn to professionals or therapists for advice on health care and lifestyle? Should people believe that being in the best of health is the main concern in their lives? The cultu

Games are a radically transnational medium: as Martin Lister writes in New Media: An Introduction, 'even before Pokemon, the videogame was perhaps the most thoroughly transnational form of popular culture, both as an industry (with Sony, Sega and Nintendo as the key players) but also at
