A Foundational Proposal for Making the Durham Statement Real

This outline is an attempt to synthesize the issues surrounding the ambitious project of the Durham Statement on Open Access to Legal Scholarship into a coherent, though still quite preliminary solution. At the heart is the conviction that the problems of digital publishing are best solved by a stable and open organization of and by the stakeholders

Equivalence Principle Violation in Weakly Vainshtein-Screened Systems

Massive gravity, galileon and braneworld models that modify gravity to explain cosmic acceleration utilize the nonlinear field interactions of the Vainshtein mechanism to screen fifth forces in high density regimes. These source-dependent interactions cause apparent equivalence principle violations. In the weakly-screened regime violations can be especially prominent since the fifth forces are at near full strength. Since they can also be calculated perturbatively, we derive analytic solutions for illustrative cases: the motion of massive objects in compensated shells and voids and infall toward halos that are spherically symmetric. Using numerical techniques we show that these solutions are valid until the characteristic scale becomes comparable to the Vainshtein radius. We find a relative acceleration of more massive objects toward the center of a void and a reduction of the infall acceleration that increases with the mass ratio of the halos which can in principle be used to test the Vainshtein screening mechanism.Comment: 7 pages, 4 figure

LANDSAT language at our reach. First Swedish satellite. Civilization detectors

Information on the use of LANDSAT data by Argentina is presented. Details on a Swedish satellite to be completed in 1984 and to be called VIKING are reported. Attempts to contact other civilizations in space by the use of radiotelescopes are discussed

The Durham Statement Two Years Later: Open Access in the Law School Journal Environment

The Durham Statement on Open Access to Legal Scholarship, drafted by a group of academic law library directors, was promulgated in February 2009. It calls for two things: (1) open access publication of law school–published journals; and (2) an end to print publication of law journals, coupled with a commitment to keeping the electronic versions available in “stable, open, digital formats.” The two years since the Statement was issued have seen increased publication of law journals in openly available electronic formats, but little movement toward all-electronic publication. This article discusses the issues raised by the Durham Statement, the current state of law journal publishing, and directions forward
