Karen Kiil Brøcker successfully defended her PhD dissertation "Justifying the evidential use of intuitive judgements in linguistics". External examiners were Michael Devitt (CUNY) and Ewa Dąbrowska (Birmingham, UK). 

Dissertation abstract:

Does it make sense to use speakers’ intuitive judgements about sentences as a source of evidence in linguistics, and if so, why? This question has been hotly debated in the philosophical literature, but it has received little attention within the field of linguistics itself. In her PhD defence, Karen summarises the main philosophical accounts of why linguistic intuitive judgements can serve as evidence and presents the results of a questionnaire study in which linguists gave their opinions on the topic. She furthermore presents her own account of why and under which circumstances linguistic intuitive judgements can serve as evidence
