Nameless in Cyberspace: Anonymity on the Internet

Proposals to limit anonymous communications on the Internet would violate free speech rights long recognized by the Supreme Court. Anonymous and pseudonymous speech played a vital role in the founding of this country. Thomas Paine's Common Sense was first released signed, "An Englishman." Alexander Hamilton, John Jay, James Madison, Samuel Adams, and others carried out the debate between Federalists and Anti-Federalists using pseudonyms. Today, human rights workers in China and many other countries have reforged the link between anonymity and free speech. Given the importance of anonymity as a component of free speech, the cost of banning anonymous Internet speech would be enormous. It makes no sense to treat Internet speech differently from printed leaflets or books

The Specter of Pervasiveness: Pacifica, New Media, and Freedom of Speech

Under the legal doctrine of pervasiveness, media such as television and radio get much less protection from censorship than do print media. The Supreme Court should reject the pervasiveness doctrine as a dangerously broad and vague excuse for speech regulation. If the doctrine applies to any medium, it could arguably apply to all media. The pervasiveness doctrine thus threatens to curtail the First Amendment's protection of freedom of speech. The pervasiveness doctrine relies on a crabbed view of individual responsibility and property rights. We invite the broadcast media into our homes and alone bear the responsibility for controlling our children's access. The pervasiveness doctrine wrongly puts such choices in the hands of politicians and bureaucrats. Technological advances threaten to lead to wider applications of the pervasiveness doctrine. As the Internet expands into one-to-many voice or video communications, courts might decide to treat it as the legal equivalent of pervasive radio or TV broadcasts

Observation of Single Transits in Supercooled Monatomic Liquids

A transit is the motion of a system from one many-particle potential energy valley to another. We report the observation of transits in molecular dynamics (MD) calculations of supercooled liquid argon and sodium. Each transit is a correlated simultaneous shift in the equilibrium positions of a small local group of particles, as revealed in the fluctuating graphs of the particle coordinates versus time. This is the first reported direct observation of transit motion in a monatomic liquid in thermal equilibrium. We found transits involving 2 to 11 particles, having mean shift in equilibrium position on the order of 0.4 R_1 in argon and 0.25 R_1 in sodium, where R_1 is the nearest neighbor distance. The time it takes for a transit to occur is approximately one mean vibrational period, confirming that transits are fast.Comment: 19 pages, 8 figure

Conceptualizing Student Practice for the 21st Century: Educational and Ethical Considerations in Modernizing the District of Columbia Student Practice Rules

This article traces the history of the amendment process. It provides a short history of student practice rules and then, using the student practice rule in effect in the District of Columbia prior to the 2014 amendments, describes the various components of those rules that courts and bars across the nation have implemented to assist courts, advance legal education, and preserve advocates’ ethical obligations to clients. It then describes some of the comments to the proposed amendments offered by the District of Columbia Bar and other D.C. lawyers during the public comment period and the modifications to the District of Columbia student practice rule that the District of Columbia Court of Appeals accepted. Finally, it discusses some areas of disagreement that arose during the process and a description of the reasons for those disagreements

A Community Education and Intervention Program for Level Crossing Risk Management in Australia

This project aims to design, implement and evaluate a community road safety program using an intervention and control community methodology. It is a 3-year national project funded by the Cooperative Research Centre for Railway Engineering and Technologies in Australia. With level crossing accidents constituting a significant proportion of death and injury associated with rail operations the need to conduct research in level crossing safety is warranted. To date, there has been little research conducted in Australia that evaluates community road safety programs targeting level crossing safety as well as identifying impediments towards the development of safe level crossing behaviour
