Random polarization dynamics in a resonant optical medium

Random optical-pulse polarization switching along an active optical medium in the $\Lambda$-configuration with spatially disordered occupation numbers of its lower energy sub-level pair is described using the idealized integrable Maxwell-Bloch model. Analytical results describing the light polarization-switching statistics for the single self-induced transparency pulse are compared with statistics obtained from direct Monte-Carlo numerical simulations.Comment: 7 pages, 3 figure

Consume or Invest: What Do/Should Agency Leaders Maximize?

In the regulatory state, agency leaders face a fundamental choice: should they “consume,” or should they “invest”? “Consume” means launching high profile cases and rulemaking projects. “Invest” means developing and nurturing the necessary infrastructure for the agency to handle whatever the future may bring. The former brings headlines, while the latter will be completely ignored. Unsurprisingly, consumption is routinely prioritized, and investment is deferred, downgraded, or overlooked entirely. This Article outlines the incentives for agency leadership to behave in this way and explores the resulting agency costs (pun intended). The U.S. Federal Trade Commission’s health care portfolio provides a useful case study of how one agency managed and minimized these costs. Our Article concludes with several proposals that should help encourage agency leadership to strike a better balance between consumption and investment

Competition Agency Design: What\u27s on the Menu?

In recent years the United Kingdom and various other countries have decided to restructure the institutions responsible for enforcing competition laws. How should a nation choose among myriad alternative arrangements? This paper lays out nine major institutional choices that governments must address in designing the implementation mechanism for a competition law. The paper discusses tradeoffs associated with each choice and examines interdependencies among different design elements. In doing so, the paper offers a structured framework that countries can use in forming new competition systems or altering existing institutional arrangements

Competition Agencies with Complex Policy Portfolios: Divide or Conquer?

Antitrust law has been adopted by 120 jurisdictions worldwide. In more than half of these jurisdictions, the agency charged with enforcing antitrust law also has other responsibilities. The assignment of multiple regulatory tasks can affect the performance of a competition agency in complex and subtle ways. We present a framework for analyzing the consequences of creating public bodies with complex policy portfolios. Using examples from across the administrative state, we analyze the forces that shape the content of an agency’s policy duties, and how the portfolio of assigned duties affects the way an agency approaches its assigned tasks, and its performance of those tasks. We apply this framework to the U.S. Federal Trade Commission, whose diversified policy portfolio includes antitrust, consumer protection, and data protection/privacy

Urban robotic experimentation: San Francisco, Tokyo and Dubai

Advances in robotics, artificial intelligence and automation have the potential to transform cities and urban social life. However, robotic restructuring of the city is complicated and contested. Technology is still evolving, robotic infrastructure is expensive and there are technical, trust and safety challenges in bringing robots into dynamic urban environments alongside humans. This article examines the nascent field of ‘urban robotics’ in three emblematic yet diverse national-urban contexts that are leading centres for urban robotic experimentation. Focusing on the experimental application of autonomous social robots, the article explores: (i) the rationale for urban robotic experiments and the interests involved, and (ii) the challenges and outcomes of creating meaningful urban spaces for robotic experimentation. The article makes a distinctive contribution to urban research by illuminating a potentially far-reaching but under-researched area of urban policy. It provides a conceptual framework for mapping and understanding the highly contingent, spatially uneven and socially selective processes of robotic urban experimentation
