I have a few reservations and cautions about the significance of these rankings. At one level, having comparative benchmarks that provide at least some data about the media profile of the research conducted at universities is better than no data at all. However, there is the risk that these ranking reinforce the marketing and publicity trend among research universities, with science joining athletics as a part of the competitive branding of the university.
Instead of thinking of science communication as a publicity process, research universities need to make sure that they are instead thinking of science communication as an ongoing partnership and trust-building process. Science communication expert Rick Borchelt calls this process "managing the trust portfolio," a key approach he details in a recent book chapter in an excellent edited volume on science communication.
