It was about one and a half years ago that I finally I arrived where I had always wanted to be and do what I had always wanted-- teach students, support small language communities and conduct research on African languages on my doorstep. The University of Cape Town and my new colleagues welcomed my efforts to establish the Centre for African Language Diversity-- CALDi as well as The African Language Archive-- TALA and I was recently appointed the Mellon Research Chair: African Language Diversity this initiative. The main aim of CALDi is to train young African scholars in descriptive linguistics and open up space for research into African languages at UCT with the hopes of countering the dominance of African linguistics outside the continent. It has been a great challenge for which my whole career has been a form of preparation...Read more

Limits on global rules in Optimality Theory with Candidate Chains
In Optimality Theory with Candidate Chains (OT-CC; McCarthy ), candidates are multi-step derivations, and precedence constraints, which regulate the order of derivational steps, can inspect entire candidate derivations. This means that OT-CC opens the door to certain kinds of 'global rules' - that is, effects in which the application or non-application of a process is decided with crucial reference to derivational history. This paper investigates what limits may exist on OT-CC's global rule powers, focusing on two forms of opacity which are possible under a theory where all rules apply simultaneously, but not under sequential rule application: mutual counterfeeding and mutual counterbleeding. It is shown that the original version of OT-CC allows none, but that each of them could be made possible with relatively simple revisions to the original theory. Possible examples of these forms of opacity are discussed.
