Messengers of justice: social network analysis of public relations support for migrants.

This article applies Social Network Analysis (SNA) to illuminate the task forces created by US-based activists undertaking public relations on behalf of migrant caravan participants that travel from Honduras through Mexico toward the US. Four functional roles – influencers, messengers, support groups, and founding members – are identified and described in detail. When taking into account the characteristics of the individuals involved, these roles facilitate "bridge-actions": the mobilization of support across distinct political structures such as Native American tribal governments, international human rights venues, and US political parties. The result is a flexible public relations venture that has ability to influence diverse audiences – and extend beyond this particular mobilization effort. This has been most useful in the current American debate concerning restrictive US immigration policies and border security measures. [ABSTRACT FROM AUTHOR]
