There's another great special issue on relevance in research which appeared in Journal of Applied Behavioral Science Vol 47 Issue 1 ... it is populated by contributions from top-notch scholars and contains a number of well written and thoughtful articles. If you are doing research in the broad field of organization studies and are doing anything which relates to practice-oriented, action research, interventions, or just trying to make sense of the relationship between professional researchers and practising managers ... this is worth looking at.
Enjoy
