There are a number of markers of research fields (Good, 2000; Fensham, 2004). In particular, a research field requires a body of researchers who are working in what is recognised as a distinct area of enquiry, and who themselves associate their work with that field. These scholars should be spread across more than one institution, and major research fields tend to involve an international group of scholars. Other markers include journals and conferences dedicated, and designated, to the field – which tend to appear once there is a sufficient cadre of researchers who recognise that there is a field, and chose to locate their work within that field.
