Dialing It Back: Why Courts Should Rethink Students’ Privacy and Speech Rights as Cell Phone Communications Erode the ‘Schoolhouse Gate’

The ubiquity of cell phones in today’s society has forced courts to change or dismiss established, but inapplicable analytical frameworks. Two such frameworks in the school setting are regulations of student speech and of student searches. This Article traces the constitutional jurisprudence of both First Amendment off-campus speech protection and Fourth Amendment search standards as applied to the school setting. It then analyzes how the Supreme Court’s ruling in Riley v. California complicates both areas. Finally, it proposes a pragmatic solution: by recognizing a categorical First Amendment exception for “substantial threats” against the school community, courts could accommodate students’ constitutional rights while upholding school administrators’ ability to maintain a safe environment

Abundances of sodium, sulfur, and potassium in lunar volcanic glasses: Evidence for volatile loss during eruption

Six varieties of lunar volcanic glass are known to occur within the Apollo 17 sample collection. Investigations have shown that 25 volatile elements are known to be concentrated on the exterior surfaces of individual volcanic glass spheres. Since bulk analyses of volcanic glass provide an integrated abundance of an element on and with the glass spherules, other methods must be relied on to determine the interior abundance of an element. The interior abundance of an element with a volcanic glass sphere establishes the abundance of that element in the melt at the time of quench. The current study is part of a comprehensive attempt to measure the abundance of three volatile elements (Na, S, and K) within representative spheres of the 25 varieties of lunar volcanic glass currently known to exist at the Apollo landing sites. Comparison of the measured abundances of these elements within the interiors of individual glasses with bulk analyses and crystalline mare basalts will furnish new constraints on the geochemical behavior of volatile elements during lunar mare volcanism

Contamination from Skylab as determined from the solar coronagraph data

The white light solar coronagraph was one of the scientific telescopes flown on Skylab to study the sun. It studied the sun's atmosphere located from 0.5 to 5.0 solar radii above the sun's limb. Such a telescope is so sensitive to contamination around the spacecraft that it caused a major contamination abatement program to be initiated at the conception of Skylab. The coronagraph's data is analyzed showing the successfulness of that abatement program
