Actually, I am wondering if I should do a DBA in Manchester rather than PhD. I am wondering if this will be accepted by some universities in Hong Kong as an equivalent doctorial degree so that I can become an assistant professor in Hong Kong (assume that this is the only factor concerned)
normally the academia holds extremely different metaphors towards DBA and PhD. harvard is THE most unique example. and the business school professors @ HBS have been doing research in a non-traditional way. taking OB for example, from the first day of their doctoral training, it is vital to learn how to get connected with HBR/CMR/SML agents rather than w/ AMJ/JAP/ASQ/AMR editorial board members. they don't give a damn on publishing @ these top journals. and they would not even bother landing their tenure on these traditional publications. their graduates always found it hard to survive in a traditional setting. what they care about is how to make practical contribution by publishing books rather than journal articles. I had a professor who graduated from HBS. it was quite amazing to see that she did not even know how to do structural equation modeling. yet she has been extremely strong in other methods that could land on book publications.
from my own standpoint, i would strongly urge u NOT consider the DBA program if u wanna end up with academic placement unless u can get accepted by HBS.....
btw, GSU DOES have a PhD program which is strong and solid. don't make it wrong that they ONLY have executive DBA program.
