Can we identify the members of a community who are bestplaced to diffuse information simply by asking a random sample of individuals? We show that boundedly-rational individuals can, simply by tracking sources of gossip, identify those who are most central in a network according to “diffusion centrality,” which nests other standard centrality measures. Testing this prediction with data from 35 ...

Our tests reveal that verbal is significantly associated with both analyst asking question and CEO fielding question. First, we find male analysts are more verbally aggressive than female analysts. Specifically, direct likely to be followed further questions, have a prefa...

The membrane-proximal external region (MPER) of human immunodeficiency virus type 1 (HIV-1) gp41 bears the epitopes of two broadly neutralizing antibodies (Abs), 2F5 and 4E10, making it a target for vaccine design. A third Ab, Fab Z13, had previously been mapped to an epitope that overlaps those of 2F5 and 4E10 but only weakly neutralizes a limited set of primary isolates. Here, libraries of Fa...
