Communiqué No. 16: Escalating Pension Benefit Costs -- Another Threat to Nonprofit Survival?

Provides findings from a national survey of nonprofits that examines the benefits of nonprofit retirement programs, explores the financial stress the plans are under, and describes the coping strategies developed by organizations

Communiqué No. 19: Recession Pressures on Nonprofit Jobs

Summarizes findings from a national survey on nonprofit employment that was conducted in April 2010. The report describes evidence of workforce strain during the current recession with increased demand for services. Nonprofit have also demonstrated resilience in maintaining staffing levels

Communiqué No. 15: Health Care and Nonprofits: The Hidden Dimension of America's Health Care Crisis

Providings findings from a national survey that examines how nonprofits and their employees are affected by rising health care costs

New string vacua from twistor spaces

We find a new family of AdS_4 vacua in IIA string theory. The internal space is topologically either the complex projective space CP^3 or the "flag manifold" SU(3)/(U(1)xU(1)), but the metric is in general neither Einstein nor Kaehler. All known moduli are stabilized by fluxes, without using quantum effects or orientifold planes. The analysis is completely ten--dimensional and does not rely on assumptions about Kaluza--Klein reduction.Comment: 19 pages. v3: published version, further minor correction

Nanoscale magnetic structure of ferromagnet/antiferromagnet manganite multilayers

Polarized Neutron Reflectometry and magnetometry measurements have been used to obtain a comprehensive picture of the magnetic structure of a series of La{2/3}Sr{1/3}MnO{3}/Pr{2/3}Ca{1/3}MnO{3} (LSMO/PCMO) superlattices, with varying thickness of the antiferromagnetic (AFM) PCMO layers (0<=t_A<=7.6 nm). While LSMO presents a few magnetically frustrated monolayers at the interfaces with PCMO, in the latter a magnetic contribution due to FM inclusions within the AFM matrix was found to be maximized at t_A~3 nm. This enhancement of the FM moment occurs at the matching between layer thickness and cluster size, where the FM clusters would find the optimal strain conditions to be accommodated within the "non-FM" material. These results have important implications for tuning phase separation via the explicit control of strain.Comment: 4 pages, submitted to PR

EUV and X-ray spectroheliograph study

The results of a program directed toward the definition of an EUV and X-ray spectroheliograph which has significant performance and operational improvements over the OSO-7 instrument are documented. The program investigated methods of implementing selected changes and incorporated the results of the study into a set of drawings which defines the new instrument. The EUV detector performance degradation observed during the OSO-7 mission was investigated and the most probable cause of the degradation identified

Communiqué No. 10: A Nonprofit Workforce Action Agenda

Presents findings from the Listening Post Project roundtable on nonprofit recruitment and retention that was convened on March 5, 2008
