If '10 means 2010 and '14 stands for 2014, they are the timeframe (2008-2013) but are still unclear what they actually mean.

It turns out, however, that American voters don’t penalize women who seem ambitious, according to a new paper published in the journal Political Behavior by Sparsha Saha, M.A. ’10 Ph.D. ’14, a political scientist and lecturer in Harvard’s Government Department. Despite the vast body of literature on voter behavior, Saha and her co-author, Ana Catalano Weeks, Ph.D. ’16, assistant professor at the University of Bath, say it’s the first study of voter perceptions of candidate ambition.
