The Andrew W. Mellon Foundation Art Museum Staff Demographic Survey

The Andrew W. Mellon Foundation, in partnership with the Association of Art Museum Directors (AAMD) and the American Alliance of Museums (AAM), has announced the results of the first comprehensive survey to assess the ethnic and gender diversity of the staffs of art museums across the United States. Undertaken to replace anecdotal evidence with hard data, the survey provides the museum field with the first statistical baseline against which progress can be measured. Art Museum Staff Demographic SurveyAmong its chief findings, the survey documented a significant movement toward gender equality in art museums. Women now comprise some 60 percent of museum staffs, with a preponderance of women in the curatorial, conservation and education roles that can be a pipeline toward leadership positions. The survey found no such pipeline toward leadership among staff from historically underrepresented minorities. Although 28 percent of museum staffs are from minority backgrounds, the great majority of these workers are concentrated in security, facilities, finance, and human resources jobs. Among museum curators, conservators, educators and leaders, only 4 percent are African American and 3 percent Hispanic

Pre- and postprocessing techniques for determining goodness of computational meshes

Research in error estimation, mesh conditioning, and solution enhancement for finite element, finite difference, and finite volume methods has been incorporated into AUDITOR, a modern, user-friendly code, which operates on 2D and 3D unstructured neutral files to improve the accuracy and reliability of computational results. Residual error estimation capabilities provide local and global estimates of solution error in the energy norm. Higher order results for derived quantities may be extracted from initial solutions. Within the X-MOTIF graphical user interface, extensive visualization capabilities support critical evaluation of results in linear elasticity, steady state heat transfer, and both compressible and incompressible fluid dynamics

Mechanical effect of van der Waals interactions observed in real time in an ultracold Rydberg gas

We present time-resolved spectroscopic measurements of Rydberg-Rydberg interactions in an ultracold gas, revealing the pair dynamics induced by long-range van der Waals interactions between the atoms. By detuning the excitation laser, a specific pair distribution is prepared. Penning ionization on a microsecond timescale serves as a probe for the pair dynamics under the influence of the attractive long-range forces. Comparison with a Monte Carlo model not only explains all spectroscopic features but also gives quantitative information about the interaction potentials. The results imply that the interaction-induced ionization rate can be influenced by the excitation laser. Surprisingly, interaction-induced ionization is also observed for Rydberg states with purely repulsive interactions

Management practices and sugar end potatoes

French fries processed from sugar end potatoes become undesirably dark on one end while remaining light on the other (fig. 1). The darkening is usually caused by a higher concentration of reducing sugars in the darkened end of the fry strip. Sugar ends are associated with tubers that are pointed on the stem end but also occur in ideally shaped tubers. "Translucent end," "jelly end," and "sugar end" describe the same physiological tuber problem. Translucent end tubers with high levels of sugars develop jelly end rot after progressive tissue breakdown occurs. The Russet Burbank variety is particularly susceptible to sugar end formation when subjected to water and heat stress
