Query: A Ph.D. should know better

Grammar and spelling errors begin on the first page of this disappointing book. Shouldn't a Ph.D. know how to spell "Gandhi"? (She spells it "Ghandi.") Shouldn't a highly educated author know better than to put the periods outside the quotation marks?I found the chapters to be simply statements of the obvious: "Be nice to students," "Be available," "Keep a positive attitude."Not much of substance here for an aspiring prof.
