In her analysis of transnational advocacy campaigns around labor and economic rights within the broader human rights advocacy frame-work, Shareen Hertel emphasizes the ability of activists within countries and their transnational allies to impact and even shift the agendas of the campaigns. Hertel uses two high profile transnational advocacy campaigns to expand our understanding of the mechanisms in the evolution of norms and framing of human rights claims within such campaigns. Delivering a multifaceted explanation of the genesis and evolution of both campaigns, Hertel synthesizes rationalist, structural, and social movement analyses. Drawing upon Jonathan Fox's work, Hertel evaluates the effects of both campaigns with almost a decade's distance. In the end, she draws the conclusion that blocking produces more significant changes than backdoor movements.(Mobilization)
