Testimony issued by the Government Accountability Office with an abstract that begins "Few issues generate more attention and anxiety among American consumers than the price of gasoline. The most current upsurge in prices is no exception. According to data from the Energy Information Administration (EIA), the average retail price of regular unleaded gasoline in the United States has increased almost every week this year since January 29th and reached an all-time high of $3.10 the week of May 14th. Over this time period, the price has increase 94 cents per gallon and added about $20 billion to consumers' total gasoline bill, or about $146 for each passenger car in the United States. Given the importance of gasoline for the nation's economy, it is essential to understand the market for gasoline and the factors that influence gasoline prices. In this context, this testimony addresses the following questions: (1) what key factors affect the prices of gasoline and (2) what effects have mergers had on market concentration and wholesale gasoline prices? To address these questions, GAO relied on previous reports, including a 2004 GAO report on mergers in the U.S. petroleum industry, a 2005 GAO primer on gasoline prices and a 2006 …

Testimony issued by the Government Accountability Office with an abstract that begins "Although the overall safety record in the railroad industry, as measured by the number of train accidents per million miles traveled, has improved markedly since 1980, there has been little sustained improvement over the past decade. Serious accidents resulting in injuries and deaths continue to occur, such as one in Graniteville, South Carolina, in 2005 that resulted in 9 deaths and 292 injuries. The Federal Railroad Administration (FRA) develops safety standards and inspects and enforces railroads' compliance with these standards. On January 26, 2007, GAO reported on FRA's overall safety oversight strategy. (See GAO-07-149.) The report discussed how FRA (1) focuses its efforts on the highest priority risks related to train accidents in planning its oversight, (2) identifies safety problems on railroad systems in carrying out its oversight, and (3) assesses the impact of its oversight efforts on safety. GAO recommended that FRA (1) put into place measures of the results of its inspection and enforcement programs and (2) evaluate its enforcement program. In its response, the Department of Transportation stated that FRA agreed to develop such measures and would consider requesting additional resources to conduct an evaluation …

Testimony issued by the Government Accountability Office with an abstract that begins "About two-thirds of drugs that are prescribed for children have not been studied and labeled for pediatric use, placing children at risk of being exposed to ineffective treatment or incorrect dosing. The Best Pharmaceuticals for Children Act (BPCA), enacted in 2002, encourages the manufacturers, or sponsors, of drugs that still have marketing exclusivity--that is, are on-patent--to conduct pediatric drug studies, as requested by the Food and Drug Administration (FDA). If they do so, FDA may extend for 6 months the period during which no equivalent generic drugs can be marketed. This is referred to as pediatric exclusivity. BPCA also provides for the study of off-patent drugs. GAO was asked to testify on the study and labeling of drugs for pediatric use under BPCA. This testimony is based on Pediatric Drug Research: Studies Conducted under Best Pharmaceuticals for Children Act, GAO-07-557 (Mar. 22, 2007). GAO assessed (1) the extent to which pediatric drug studies were being conducted under BPCA for on-patent drugs, (2) the extent to which pediatric drug studies were being conducted under BPCA for off-patent drugs, and (3) the impact of BPCA on the labeling of drugs …

Testimony issued by the Government Accountability Office with an abstract that begins "The subcommittees asked the Comptroller General of the United States to discuss recent human capital reform efforts at the U.S. Government Accountability Office (GAO). In 2004, GAO conducted its first ever market-based compensation study after laying the necessary foundation by implementing a modern, competency-based performance management system. GAO hired a top compensation consulting firm on a competitive basis to conduct a market-based pay study using generally accepted approaches and based on independent and professional judgment. As a result of the study, the 2006 pay ranges for about 25 percent of GAO's employees were raised and about 10 percent of GAO's employees were determined to be paid above market levels based on their roles, responsibilities, and/or relative performance. No GAO employee has had his or her pay cut as a result of GAO's classification and compensation changes. Still, GAO's approach to market-based pay and related Band II restructuring efforts, which were very challenging and likely unprecedented in government, have been the source of considerable attention and some controversy."

Testimony issued by the Government Accountability Office with an abstract that begins "Vigorous enforcement of anti-discrimination laws remains an essential responsibility of government. Moreover, diversity in the federal government can be a key component for executing agency missions and achieving results. Not only is it the right thing to do, but an inclusive work environment can improve retention, reduce turnover, increase our ability to recruit, and improve overall organizational effectiveness. In 2001, the Comptroller General changed the name of the Office of Civil Rights to the Office of Opportunity and Inclusiveness and gave the office responsibility for creating a fair and inclusive work environment by incorporating diversity principles in GAO's strategic plan and throughout our human capital policies. Along with this new strategic mission, the Comptroller General changed organizational alignment of the Office of Opportunity and Inclusiveness (O&I) by having the office report directly to him."

We present an update of our results for the electron-cloud build-up for several upgrades proposed for the LHC injectors. Specifically, we have re-examined our published results for the ecloud heat load [1] from the perspective of numerical convergence of the simulations vis-a-vis the integration time step {Delta}t. We repeated most of the simulations with ever smaller values of {Delta}t until we reached stable results, indicating numerical convergence; this was achieved at 200-500 slices per bunch, depending on the particular case. In all cases examined, the simulated heat load decreases monotonically, until the limit is reached, as {Delta}t decreases in the range explored, hence the stable results are more favorable vis-a-vis the heat load than the previous ones. This is particularly true for a bunch spacing t{sub b} = 25 ns.

We propose an importance truncation scheme for the no-core shell model, which enables converged calculations for nuclei well beyond the p-shell. It is based on an a priori measure for the importance of individual basis states constructed by means of many-body perturbation theory. Only the physically relevant states of the no-core model space are considered, which leads to a dramatic reduction of the basis dimension. We analyze the validity and efficiency of this truncation scheme using different realistic nucleon-nucleon interactions and compare to conventional no-core shell model calculations for {sup 4}He and {sup 16}O. Then, we present the first converged calculations for the ground state of {sup 40}Ca within no-core model spaces including up to 16{h_bar}{Omega}-excitations using realistic low-momentum interactions. The scheme is universal and can be easily applied to other quantum many-body problems.

The interactions of charged particles in a plasma are in a plasma is governed by the long-range Coulomb collision. We compare two widely used Monte Carlo models for Coulomb collisions. One was developed by Takizuka and Abe in 1977, the other was developed by Nanbu in 1997. We perform deterministic and stochastic error analysis with respect to particle number and time step. The two models produce similar stochastic errors, but Nanbu's model gives smaller time step errors. Error comparisons between these two methods are presented.

In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). The roof and the pavement albedo can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60%. We estimate U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills. Increasing albedo of urban surfaces can reduce the summertime urban temperature and improve the urban air quality. Increasing the urban albedo has the added benefit of reflecting more of the incoming global solar radiation and countering the effect of global warming. We estimate that increasing albedo of urban areas by 0.1 results in an increase of 3 x 10{sup -4} in Earth albedo. Using a simple global model, the change in air temperature in lowest 1.8 km of the atmosphere is estimated at 0.01K. Modelers predict a warming of about 3K in the next 60 years (0.05K/year). Change of 0.1 in urban albedo will result in 0.01K global cooling, a delay of {approx}0.2 years in …
