Barbara's Daughters: Women's Boxing and Social Memory in Britain
History, EarlyView.Abstract A pioneer of post‐war boxing, Barbara Buttrick fought in fairgrounds and on music‐hall stages in Britain and France before making a career in the United States during the 1950s. She fought against practical obstacles, prejudice and discrimination to become the Women's World Flyweight and Bantamweight Champion in 1957. This article examines her

Sanctions, National Security, and Free Speech
Global Policy, EarlyView.ABSTRACT A fundamental, but largely overlooked, aspect of the New Washington Consensus is the use of national security arguments to restrict speech and punish disfavored speakers. Although the United States has a longer history of using sanctions to restrict speech in the terrorism context, it has recently applied sanctions to restrict political speech,
