The easiest way to trim and hem the ragged edges of a doctorate is historically or geographically. The student can base the work on Belgium, Brazil or the Bahamas, or a particular decade, governmental term or after a significant event such as 11 September 2001. Another way to contain a project is theoretically, to state there is a focus on Henry Giroux’s model of popular culture and education rather than Henry Jenkins’ configurations of new media and literacy. Such a decision can be justified through the availability of sources, or the desire to monitor one scholar’s pathway through analogue and digital media. Examiners will feel more comfortable if they know that students have made considered choices about their area of research and understand the limits of their findings.
