Right. It's a constant problem for all universities on all aspects of the mission—learning, discovery, and engagement of the community, all of which need to be balanced. That's what research universities are contributing to Canada. As some others on the panel said earlier, patents are part of the evidence of productivity on the research side, and there can be, as Scott said earlier, vanity patents, but there can be vanity publications as well. There's a continuing need that's best met by peers in the disciplines to actually evaluate the work that people are doing.
I think the broader answer to your question is that the work of faculty members is observed and tracked through peer review within their own units, and proxies of that by others from outside who review publications and so on. We try to assess our faculty members making substantial contributions, and it can vary. Computer scientists may not have patents but they may have software. They may have ideas that may eventually become software in some company. I think it's a continual process, and overall, we look to see some macroscopic balance between teaching, research, and engagement in the actual work of solving public problems. We look into the individual departments and faculties for what the particular discriminations would be. Engineers are different. Well, Digvir is one. So—
