Each proposal consists of two parts: (1) a replication study of an existing, previously published survey experiment, and (2) a novel experimental design on a topic of the authors’ choosing. The replication studies and reanalyses of the existing studies will be combined into a meta-paper to be co-authored by all authors of accepted proposals along with the princi- pal investigators (Coppock and McGrath). As a condition for acceptance, authors commit to sharing the data and producing a write-up of the findings from their novel design for submission to a scholarly journal, and public posting of a working paper pre-publication.

Western is searching for Canada Impact+ Chairs in 8 themes including "democratic and community resilience." The program is meant for senior researchers not at Canadian unis.

Moving to Canada is a thing that profs really can do. Spread the word & get in touch.
