Experimental Evaluation of Large Scale WiFi Multicast Rate Control

WiFi multicast to very large groups has gained attention as a solution for multimedia delivery in crowded areas. Yet, most recently proposed schemes do not provide performance guarantees and none have been tested at scale. To address the issue of providing high multicast throughput with performance guarantees, we present the design and experimental evaluation of the Multicast Dynamic Rate Adaptation (MuDRA) algorithm. MuDRA balances fast adaptation to channel conditions and stability, which is essential for multimedia applications. MuDRA relies on feedback from some nodes collected via a light-weight protocol and dynamically adjusts the rate adaptation response time. Our experimental evaluation of MuDRA on the ORBIT testbed with over 150 nodes shows that MuDRA outperforms other schemes and supports high throughput multicast flows to hundreds of receivers while meeting quality requirements. MuDRA can support multiple high quality video streams, where 90% of the nodes report excellent or very good video quality

Banning Bribes Abroad: U.S. Enforcement of the Foreign Corrupt Practices Act

The United States has been at the forefront of international efforts to combat corruption in the global economy for almost forty years, chiefly through its Foreign Corrupt Practices Act (FCPA). Over the past decade, US enforcement of the FCPA has surged - both in increased numbers of enforcement actions and through the application of increasingly expansive interpretations of jurisdiction through which to enforce the FCPA on an extraterritorial basis. On one hand, extraterritorial enforcement of the FCPA has promoted anti-corruption policies and the banning of bribes abroad. At the same time, three aspects of FCPA enforcement shape and constrain the broader goals of global anti-corruption governance in ways that limit effective governance practices and meaningful anti-corruption reform in the global economy: the narrow conception of corruption upon which the FCPA is based; the strategic trade frame which underlies the FCPA’s internationalization; and the legitimacy problems these suggest

Banning Bribes Abroad: US Enforcement of the Foreign Corrupt Practices Act

The United States has been at the forefront of international efforts to combat corruption in the global economy for almost forty years, chiefly through its Foreign Corrupt Practices Act [FCPA]. Over the past decade, US enforcement of the FCPA has surged in terms of both the number of enforcement actions and the application of increasingly expansive interpretations of jurisdiction through which to enforce the FCPA on an extraterritorial basis. Extraterritorial enforcement of the FCPA has promoted anti-corruption policies and the banning of bribes abroad, but three aspects of FCPA enforcement shape and constrain the broader goals of global anti-corruption governance in ways that limit effective governance practices and meaningful anti-corruption reform in the global economy: the narrow conception of corruption upon which the FCPA is based, the strategic trade frame that underlies the FCPA’s internationalization, and the legitimacy problems these suggest
