thanks for all the great advice so far, everyone!i'm actually increasingly comfortable in my decision to dive right in for the PhD program -- i spoke to a professor at my institution, who flat-out advised me that if you come from a strong program, a master's is pretty unnecessary. plus, i think that having spent two years in the "outside world" has helped me better shape what i'm specifically interested in, to the point where i've been able to really whittle down my list of applications to those programs that have the specific scholarly support i'd need.
as for more specifics: i'm really interested in world war one and the period leading up to it, especially the experiences of those africans who served in the french army on the western front. i'm interested in how their presence affected the racialized propaganda of the war, from both a french and german perspective. schoolwise, i'm thinking about columbia, stanford, OSU, nyu, michigan-dearborn, toronto and possibly also harvard.
i guess my biggest concern has been a generalized anxiety about not being considered "serious" without a master's degree -- which is more a psychological hangup on my part than anything else. besides, the adcoms of those schools will be more than happy to judge my worthiness; my responsibility is to show them why i think i make the grade. (awful puns aside, that is!)
