Optimized second harmonic generator cel
Improved ultraviolet resonance lamp
Removal of the seal area from the path of the lamp discharge eliminates the gradual deterioration of lithium fluoride window surfaces from condensation of products formed by interaction of a resonant rare-gas discharge with window sealing materials. The discharge is confined to the inner tube
The Spin and Flavour Dependence of High-Energy Photoabsorption
We review the present data on high-energy, spin-dependent photoabsorption. We
find a strong isotriplet term in which persists from
GeV to high polarised deep inelastic scattering. For
GeV and between 0.01 and 0.12 the isotriplet part of
behaves as , in contrast to soft Regge
theory which predicts that should converge as . The
isotriplet, polarised structure function is significantly
greater than the isotriplet, unpolarised structure function in
this kinematic region. We analyse the low photoabsorption data from E-143
and SMC and use this data to estimate the high-energy Regge contribution to the

“Resistance is our Culture”: An Archival Exploration of Oromo Diaspora Organizing
The Oromo people of the Horn of Africa have been engaged in a struggle for liberation and justice since their colonization by the Abyssinian Empire in the 1880s. Despite, beyond, and against this discursive violence, Oromo people have been creating liberatory spaces and alternative stories of Oromo life. In this article I explore resistance writing and organizational materials created by members of the Oromo diaspora in the 1970s and 1980s. This archival collection, housed in Berlin, Germany, shares a story of transnational solidarity. It also demonstrates the power of the archive itself as an active participant in documenting, remembering, and supporting the Oromo struggle
The Impact of a Clinical Faculty Institute on Participants\u27 Skills for Mentoring Novice Teachers, Grades K-8
A seven-day Clinical Faculty Institute was implemented to increase the skills of mentor teachers and to develop a cadre of Clinical Faculty for the four participating colleges and universities. The 128 participants entered with some confidence in their ability to mentor novice teachers in areas typically taught in methods courses; whereas, they displayed minimal confidence in skills typically taught in supervisory courses. By the end of the Institute, participants showed significant changes in their self-perceptions of skills in twenty areas, with post-scores clustering between 3.5 and 3.9 on a four-point scale. Future institutes should focus on supervisory skills and then emphasize more reflection upon the congruence of teaching, with the best practices articulated in national standards
