title: Political Persuasion and Attitude Change Study: The Los Angeles Longitudinal Field Experiments, 2013-2014

description: A randomized placebo-controlled trial assessed whether gay (n = 22) or straight (n = 19) messengers were effective at encouraging voters (n = 972) to support same-sex marriage and whether attitude change persisted and spread to others in voters’ social networks. The results, measured by an unrelated panel survey, show that both gay and straight canvassers produced large effects initially, but only gay canvassers’ effects persisted in 3-week, 6-week, and 9-month follow-ups. We also find strong evidence of within-household transmission of opinion change, but only in the wake of conversations with gay canvassers. Contact with gay canvassers further caused substantial change in the ratings of gay men and lesbians more generally. These large, persistent, and contagious effects were confirmed by a follow-up experiment. Contact with minorities coupled with discussion of issues pertinent to them is capable of producing a cascade of opinion change.

title: X-Ray Diffraction data from Thermoanaerobacter tengcongensis SONO (H-NOX) in complex with dioxygen, source of 1XBN structure

description: This is a three wavelength MAD data collected at the iron edge.  E1 = 7134.03 eV;  E2 = 7634 eV;  E3 = 7124.35 eV.  Bijvoet pairs were collected in real time using a 1 deg wedge (inverse beam), which is the standard protocol at ALS beamline 8.3.1.  
Data identifier:  Sono2: mpd1_1_E1_###  to mpd1_1_E3_###
description: An independent archive of these images is maintained by Dr. James Holton (jmholton@lbl.gov) in the context of non-proprietary data collected at ALS beamline 8.3.1.  If necessary, this MAD dataset can also be obtained directly from Dr. Holton.

title: Political Persuasion and Attitude Change Study: The Los Angeles Longitudinal Field Experiments, 2013-2014

description: A randomized placebo-controlled trial assessed whether gay (n = 22) or straight (n = 19) messengers were effective at encouraging voters (n = 972) to support same-sex marriage and whether attitude change persisted and spread to others in voters’ social networks. The results, measured by an unrelated panel survey, show that both gay and straight canvassers produced large effects initially, but only gay canvassers’ effects persisted in 3-week, 6-week, and 9-month follow-ups. We also find strong evidence of within-household transmission of opinion change, but only in the wake of conversations with gay canvassers. Contact with gay canvassers further caused substantial change in the ratings of gay men and lesbians more generally. These large, persistent, and contagious effects were confirmed by a follow-up experiment. Contact with minorities coupled with discussion of issues pertinent to them is capable of producing a cascade of opinion change.
