Patrick McAloon is a PhD candidate at the Ohio State University writing his dissertation on Americans with professional-level Chinese language ability and how the Chinese with whom they interact evaluate them.
McAloon is seeking individuals to participate in his research which involves observing the participants at work, and using digital samples of language use to create online performance portfolios that they can use to demonstrate their skill to current and future employers.
If you know any foreigners who use advanced Mandarin ability for work in Beijing, Shanghai or Shenzhen/Guangzhou that could participate in his research — or are one yourself — please get in touch with Patrick at mcaloon.1@osu.edu for more details.
