I think it is Alan Bryman, but, like Shirley Waites-Howard, he is not an author I am familiar with. I was not sure whether you wanted researchers personal opinion of the book or if you wanted to find out more about it.
In case you have not seen the book and it would help to view it, I found a pdf of the volume by inputting the heading (below) into Google:
