Correspondence issued by the Government Accountability Office with an abstract that begins "This report responds to Congress's request that GAO determine the status and estimated costs of environmental cleanup on the island of Vieques. For decades, the U.S. Navy conducted ship-to-shore bombing exercises and other live-fire training activities on the island, which is located off the coast of Puerto Rico. The Navy ceased its operations on Vieques in 2003. The Navy has transferred the land to the Municipality of Vieques and the Puerto Rico Conservation Trust for conservation purposes and to the Department of the Interior. Although the land has been transferred, the Navy remains responsible for environmental cleanup. The cleanup is being carried out under the Defense Environmental Restoration Program (DERP) that consists of (1) the Installation Restoration Program, which addresses cleanup of hazardous substances, and (2) the Military Munitions Response Program, which addresses cleanup of munitions."

A letter report issued by the Government Accountability Office with an abstract that begins "In 1998 and 1999 reports, GAO concluded that enforcement actions, known as sanctions, were ineffective in encouraging nursing homes to maintain compliance with federal quality requirements: sanctions were often rescinded before being implemented because homes had a grace period to correct deficiencies. In response, the Centers for Medicare & Medicaid Services (CMS) began requiring immediate sanctions for homes that repeatedly harmed residents. Using CMS enforcement and deficiency data, GAO (1) analyzed federal sanctions from fiscal years 2000 through 2005 against 63 homes previously reviewed and (2) assessed CMS's overall management of enforcement. The 63 homes had a history of harming residents and were located in 4 states that account for about 22 percent of homes nationwide."

Correspondence issued by the Government Accountability Office with an abstract that begins "On January 17, 2007, GAO testified before Congress on the Department of Defense's (DOD) management of its acquisition of services. GAO made several key points during the hearing. First, DOD's long-standing problems with contract management have become more prominent as DOD's reliance on contractors to provide services continues to grow. Second, DOD lacks sound contracting practices when acquiring services. Third, DOD's acquisition workforce has been downsized without sufficient attention to requisite skills and competencies. Fourth, DOD's acquisitions have resulted in outcomes that have cost the department valuable resources. And, finally, while DOD is taking some steps to address these problems, it does not know how well its services acquisition processes are working, which part of its mission can best be met through buying services, and whether it is obtaining the services it needs while protecting DOD's and the taxpayer's interests. Within this context, members of Congress requested that GAO provide additional comments on DOD's efforts regarding the following topics: interagency contracting, acquisition of services, acquisition reform, and the acquisition workforce."

A letter report issued by the Government Accountability Office with an abstract that begins "The Medicaid program paid for nearly one-half of the nation's total long-term care expenditures in 2004. To be eligible for Medicaid long-term care, individuals may transfer assets (income and resources) to others to ensure that their assets fall below certain limits. Individuals who make transfers for less than fair market value (FMV) can be subject to a penalty that may delay Medicaid coverage. The Deficit Reduction Act of 2005 (DRA) changed the calculation and timing of the penalty period and set requirements for the treatment of certain types of assets. GAO was asked to provide data on the extent to which asset transfers for less than FMV occur. GAO examined (1) the financial characteristics of elderly nursing home residents nationwide, (2) the demographic and financial characteristics of a sample of Medicaid nursing home applicants, (3) the extent to which these applicants transferred assets for less than FMV, and (4) the potential effects of the DRA provisions related to Medicaid eligibility for long-term care. GAO analyzed data from the Health and Retirement Study (HRS), a national panel survey, and from 540 randomly selected Medicaid nursing home application …

Compositional data are represented as vector variables with individual vector components ranging between zero and a positive maximum value representing a constant sum constraint, usually unity (or 100 percent). The earth sciences are flooded with spatial distributions of compositional data, such as concentrations of major ion constituents in natural waters (e.g. mole, mass, or volume fractions), mineral percentages, ore grades, or proportions of mutually exclusive categories (e.g. a water-oil-rock system). While geostatistical techniques have become popular in earth science applications since the 1970s, very little attention has been paid to the unique mathematical properties of geostatistical formulations involving compositional variables. The book 'Geostatistical Analysis of Compositional Data' by Vera Pawlowsky-Glahn and Ricardo Olea (Oxford University Press, 2004), unlike any previous book on geostatistics, directly confronts the mathematical difficulties inherent to applying geostatistics to compositional variables. The book righteously justifies itself with prodigious referencing to previous work addressing nonsensical ranges of estimated values and error, spurious correlation, and singular cross-covariance matrices.

In the context of eternal inflation we discuss the fate of Lambda = 0 bubbles when they collide with Lambda< 0 crunching bubbles. When the Lambda = 0 bubble is supersymmetric, it is not completely destroyed by collisions. If the domain wall separating the bubbles has higher tension than the BPS bound, it is expelled from the Lambda = 0 bubble and does not alter its long time behavior. If the domain wall saturates the BPS bound, then it stays inside the Lambda = 0 bubble and removes a finite fraction of future infinity. In this case, the crunch singularity is hidden behind the horizon of a stable hyperbolic black hole.

Within a constrained carbon environment, the risks of future natural gas supply, and the need to move to market-based electricity prices, the study team found: (1) the deployment of new nuclear energy in Poland itself is very competitive in the next decade or two; (2) if such generation could be made available to Poland prior to deployment of its own nuclear generation facilities, Poland would benefit from partnering with its Baltic neighbors to import electricity derived from new nuclear generation facilities sited in Lithuania; and (3) Poland appears to be a good candidate for a partnership in the Global Nuclear Energy Partnership (GNEP) as an emerging nuclear energy country.

We investigate the climate forcing from and response to projected changes in short-lived species and methane under the A1B scenario from 2000-2050 in the GISS climate model. We present a meta-analysis of new simulations of the full evolution of gas and aerosol species and other existing experiments with variations of the same model. The comparison highlights the importance of several physical processes in determining radiative forcing, especially the effect of climate change on stratosphere-troposphere exchange, heterogeneous sulfate-nitrate-dust chemistry, and changes in methane oxidation and natural emissions. However, the impact of these fairly uncertain physical effects is substantially less than the difference between alternative emission scenarios for all short-lived species. The net global mean annual average direct radiative forcing from the short-lived species is .02 W/m{sup 2} or less in our projections, as substantial positive ozone forcing is largely offset by negative aerosol direct forcing. Since aerosol reductions also lead to a reduced indirect effect, the global mean surface temperature warms by {approx}0.07 C by 2030 and {approx}0.13 C by 2050, adding 19% and 17%, respectively, to the warming induced by long-lived greenhouse gases. Regional direct forcings are large, up to 3.8 W/m{sup 2}. The ensemble-mean climate response shows little regional …

Direct laser heating of molecular N2 to above 1400 K at 120-130 GPa results in the formation of a reddish amorphous phase and a transparent crystalline solid above 2000 K. Raman and x-ray data confirm that the transparent phase is cubic-gauche nitrogen (cg-N), while the reddish color of the amorphous phase might indicate the presence of N=N dish bonds. The quenched amorphous phase is stable down to at least 70GPa, analogous to cg-N, and could be a new non-molecular phase or an extension of the already known {eta}-phase. A chemo-physical phase diagram is presented which emphasizes the difference between pressure- and temperature-induced transitions from molecular to non-molecular solids, as found in other low Z systems.

We study the energy dependence of the transverse momentum (pT) spectra for charged pions, protons and anti-protons for Au+Au collisions at sqrt sNN = 62.4 and 200 GeV. Data are presented at mid-rapidity (lbar y rbar< 0.5) for 0.2< pT< 12 GeV/c. In the intermediate pT region (2< pT< 6 GeV/c), the nuclear modification factor is higher at 62.4 GeV than at 200 GeV, while at higher pT (pT> 7 GeV/c) the modification is similar for both energies. The p/pi+ and pbar/pi- ratios for central collisions at sqrt sNN = 62.4 GeV peak at pT _~;; 2 GeV/c. In the pT range where recombination is expected to dominate, the p/pi+ ratios at 62.4 GeV are larger than at 200 GeV, while the pbar/pi- ratios are smaller. For pT> 2 GeV/c, the pbar/pi- ratios at the two beam energies are independent of pT and centrality indicating that the dependence of the pbar/pi- ratio on pT does not change between 62.4 and 200 GeV. These findings challenge various models incorporating jet quenching and/or constituent quark coalescence.
