Peter Campbell and Michael Desch have developed new rankings of scholars and universities. The authors take specific issue with NRC rankings. Here is their description at Foreign Affairs (ungated for 4 weeks):
With the generous support of the Carnegie Corporation of New York, we have ranked the top fifty political science departments based on 37 different measures of scholarly excellence and broader policy relevance of their international relations faculty. We have done the same thing for the 442 individual scholars in that group. The full results are available here: www.nd.edu/~carnrank.
Have fun with the data and report back with interesting findings.
