Thesis advisor: Donald Fishman / The whistleblower has emerged as a relevant player in today's shifting economic and corporate landscape. Using a critical-historical methodology, this thesis explores the dimensions and boundaries of the concept of the “whistleblower”. The specific case studies of WorldCom, the Madoff Ponzi scheme, and WikiLeaks are examined. The analysis includes an investigation into the shifting role of the whistleblower in society and whether legislative enactments have been able to support society’s need to protect current and future whistleblowers. Finally, this thesis examines the whistleblower's implications for a more ethical future. / Thesis (BA) — Boston College, 2012. / Submitted to: Boston College.
