Forthright and frank in his comments about the limitations and practical implications of varying choices which investigators have to make in designing their research projects. Reading this text is like having a tough but expert and caring mentor who wants you to do the best research possible, but will not hesitate to tell you when your ideology and assumptions skew that possibility' - Vincent W Hevern, Le Moyne College, USA.
