Correspondence issued by the Government Accountability Office with an abstract that begins "Oil and gas production from federal lands and waters is critical to meeting the nation's energy needs. This production provided about 31 percent of all oil and 29 percent of all natural gas produced in the United States in fiscal year 2007. Every five years, the federal government decides the areas in the offshore waters of the United States it will offer for leasing and establishes a schedule for individual lease sales. The Department of the Interior's Minerals Management Service (MMS) has conducted these sales at least once per year for at least the past 30 years. During the sales, oil and gas companies bid for the rights to explore and develop the oil and gas resources on these leases and also agree to pay the federal government royalties on the resources produced. In 1995, a time when oil and natural gas prices were significantly lower than they are today, Congress passed the Outer Continental Shelf Deep Water Royalty Relief Act (DWRRA), which authorized MMS to provide "royalty relief" on oil and gas produced in the deep waters of the Gulf of Mexico from certain leases issued from …

A letter report issued by the Government Accountability Office with an abstract that begins "Health-care-associated infections (HAI) are infections that patients acquire while receiving treatment for other conditions. Normally treated with antimicrobial drugs, HAIs are a growing concern as exposure to multidrug-resistant organisms (MDRO) becomes more common. Infections caused by MDROs, such as methicillin-resistant Staphylococcus aureus (MRSA), lead to longer hospital stays, higher treatment costs, and higher mortality. In response to demands for more public information on HAIs, some states began to establish HAI public reporting systems. The federal Centers for Disease Control and Prevention (CDC) developed a system--the National Healthcare Safety Network (NHSN)--to collect HAI data from hospitals and some states have chosen to use it for their programs. In addition, some hospitals have adopted initiatives to reduce MRSA by routinely testing some or all patients and isolating those who test positive for MRSA from contact with other patients. GAO was asked to examine (1) the design and implementation of state HAI public reporting systems, (2) the initiatives hospitals have undertaken to reduce MRSA infections, and (3) the experience of certain early-adopting hospitals in overcoming challenges to implement such initiatives. GAO interviewed state officials, reviewed documents, and surveyed or …

A letter report issued by the Government Accountability Office with an abstract that begins "To help defray the cost of prescription drugs for beneficiaries with limited means, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) included the low-income subsidy (LIS) in the Part D prescription drug insurance program. To qualify for the LIS, beneficiaries must be enrolled in a Part D plan and their assets and income must be less than the thresholds established by the law. Part D is administered by the Centers for Medicare & Medicaid Services (CMS), and the Social Security Administration (SSA) administers the eligibility determination for the LIS. The MMA directed GAO to compare the utilization of and access to Part D prescription drugs among beneficiaries who received the LIS with those who were denied it because of the amount of their assets. This report focuses on beneficiaries' access to prescription drugs by examining (1) the importance of assets and income in LIS denials in 2006 and 2007, and (2) state and manufacturer programs providing access to prescription drugs for Medicare beneficiaries. To do this, GAO analyzed data from SSA, reviewed information on state and drug manufacturer pharmaceutical programs, and interviewed officials …

A letter report issued by the Government Accountability Office with an abstract that begins "Genetically engineered (GE) crops--including crops engineered to resist pests or tolerate herbicides--are widespread in the United States and around the world. Taking direction from the 1986 Coordinated Framework for Regulation of Biotechnology, the U.S. Department of Agriculture (USDA), Environmental Protection Agency (EPA), and Food and Drug Administration (FDA) regulate GE crops to ensure that they are safe. The unauthorized mixing of some GE crops with non-GE crops has caused controversy and financial harm. GAO examined (1) unauthorized releases of GE crops, (2) coordination among the three agencies, and (3) additional actions they have proposed to improve oversight. GAO gathered data from agencies and stakeholders; used criteria from prior GAO work to assess coordination; and reviewed agency proposals."

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Department of the Interior's Bureau of Land Management (BLM), Fish and Wildlife Service, and National Park Service, and the U.S. Department of Agriculture's Forest Service manage about 628 million acres of public land, mostly in the 11 western states and Alaska. Under the Federal Land Transaction Facilitation Act (FLTFA), revenue raised from selling BLM lands is available to the agencies, primarily to acquire nonfederal land within the boundaries of land they already own--known as inholdings, which can create significant land management problems. To acquire land, the agencies can nominate parcels under state-level interagency agreements or the Secretaries can use their discretion to initiate acquisitions. FLTFA expires in 2010. GAO was asked to determine (1) FLTFA revenue generated, (2) challenges to future sales, (3) FLTFA expenditures, and (4) challenges to future acquisitions. To address these issues, GAO interviewed officials and examined the act, agency guidance, and FLTFA sale and acquisition data."

A letter report issued by the Government Accountability Office with an abstract that begins "Since September 11, 2001, a concern has been that terrorists or their supporters would seek to immigrate to the United States (i.e., seek lawful permanent residency (LPR)). The Department of Homeland Security's U.S. Citizenship and Immigration Services (USCIS) conducts background checks and the FBI conducts name checks for those applying for LPR. GAO was asked to review USCIS's processes for screening individuals applying for LPR. GAO assessed: (1) what available data show about the extent to which national security concerns were discovered during USCIS background checks for LPR applications, (2) what issues USCIS has encountered in its background check processes and what actions have been taken to resolve those issues, and (3) the extent to which USCIS has addressed fraud vulnerabilities in its adjudication procedures for LPR. To conduct this work, GAO analyzed USCIS background check and adjudication procedures, USCIS data on adjudications, and its assessments of fraud in applications for LPR, and interviewed USCIS and FBI officials."

Correspondence issued by the Government Accountability Office with an abstract that begins "Taxpayers who do not want to wait for their tax refunds from the Internal Revenue Service (IRS) may choose to obtain refund anticipation loans (RAL). RALs are short-term, high-interest bank loans that are advertised and brokered by both national chain and local tax preparation companies. Although the annual percentage rate (APR) on RALs can be over 500 percent, they allow taxpayers to receive cash refunds quickly--sometimes within the same day and even within an hour of filing their tax returns. After filing a taxpayer's return electronically, the tax preparer works in cooperation with a bank to advance the refund as a loan minus tax preparation costs, other fees, and a finance charge. As part of the RAL process, the taxpayer provides authorization to IRS to send the refund directly to the bank to repay the loan. Despite the benefits of receiving cash quickly based on an expected refund, IRS officials and others have raised concerns about whether taxpayers are fully aware of the costs involved and their tax filing alternatives. For example, in a 2007 report to Congress, the IRS National Taxpayer Advocate questioned whether RAL consumers actually …

Testimony issued by the Government Accountability Office with an abstract that begins "The current economic downturn has brought significant financial stress to the auto manufacturing industry. Recent deteriorating financial, real estate, and labor markets have reduced consumer confidence and available credit, and automobile purchases have declined. While auto manufacturers broadly have experienced declining sales in 2008 as the economy has worsened, sales of the "Big 3" (General Motors, Chrysler, and Ford) have also declined relative to those of some other auto manufacturers in recent years because higher gasoline prices have particularly hurt sales of sport utility vehicles. In addition to causing potential job losses at auto manufacturers, failure of the domestic auto industry would likely adversely affect other sectors. Officials from the Big 3 have requested, and Congress is considering, immediate federal financial assistance. This testimony discusses principles that can serve as a framework for considering the desirability, nature, scope, and conditions of federal financial assistance. Should Congress decide to provide financial assistance, we also discuss how these principles could be applied in these circumstances. The testimony is based on GAO's extensive body of work on previous federal rescue efforts that dates back to the 1970s."

Testimony issued by the Government Accountability Office with an abstract that begins "Of the $11 billion total estimated cost of the 2010 Census, the Census Bureau planned (as of 2007) to spend about $3 billion on automation and information technology in order to improve census coverage, accuracy, and efficiency. Among other things, the Bureau is planning to automate many of its planned field data collection activities as a way to reduce costs and improve data quality and operational efficiency. Known as Field Data Collection Automation (FDCA), this initiative is acquiring handheld mobile computing devices that, along with other technology, are undergoing operational testing during a Census "Dress Rehearsal" that is taking place from February 2006 to June 2009. The $600 million FDCA program is a crucial component of the reengineered processes envisioned for the 2010 Census. In March 2006, GAO reported on the management capabilities of the FDCA program, and in October 2007, it reported on FDCA's status and plans. As requested, this testimony summarizes key findings from these two reports, as well as subsequent Bureau actions."

Testimony issued by the Government Accountability Office with an abstract that begins "The Deepwater Program is intended to replace or modernize 15 major classes of Coast Guard assets--including vessels, aircraft, and communications systems. At the program's start, the Coast Guard chose to use a system integrator, Integrated Coast Guard Systems, to design, build, deploy, and support Deepwater in a system-of-systems approach. In a series of reports, we have noted the risks inherent in this approach. With the Deepwater program under way, the Coast Guard's priorities and focus shifted after September 11 toward homeland security missions, such as protecting the nation's ports and waterways. The 2002 Maritime Transportation Security Act and the 2006 SAFE Port Act required a wide range of security improvements. GAO is monitoring the acquisition of Deepwater and the Coast Guard's ability to carry out its numerous missions. This testimony addresses: (1) changes the Coast Guard is making as it assumes a larger role in managing the Deepwater Program and (2) challenges the Coast Guard is facing in carrying out its various missions. To conduct this work, GAO reviewed key documents, such as Deepwater acquisition program baselines, human capital plans, and Coast Guard budget and performance documents. For …

A letter report issued by the Government Accountability Office with an abstract that begins "Iraq has an estimated 115 billion barrels of crude oil reserves, the third largest in the world. Oil export revenues are critical to Iraq's reconstruction, accounting for over 90 percent of the Iraqi government's revenues. In June 2008, GAO reported low 2007 spending rates by the Iraqi government for some critical sectors in the face of declining U.S. investments in these sectors. This report examines (1) Iraq's estimated revenues from 2005 through 2008, (2) Iraq's estimated expenditures from 2005 through 2008, (3) Iraq's financial deposits through 2007 and budget surpluses, (4) U.S. cumulative expenditures on stabilization and reconstruction activities in Iraq since 2003, and (5) factors affecting Iraq's efforts to accelerate spending. GAO analyzed relevant data and reviewed documents, including Central Bank of Iraq oil receipts data, International Monetary Fund's (IMF) reports, translated copies of Iraqi budget and expenditures, and U.S. agency funding data and reports. GAO also interviewed officials from the Departments of Defense (DOD), Energy, State, Treasury, and the IMF. This report contains no recommendations. Treasury agreed with the report's findings and stated that Iraq has adequate funds to make and maintain capital investments …

Testimony issued by the Government Accountability Office with an abstract that begins "The Congress and the President need to have reliable, useful and timely financial and performance information to make sound decisions on the current and future direction of vital federal government programs and policies. Unfortunately, except for the 2007 Statement of Social Insurance, GAO was again unable to provide assurance on the reliability of the consolidated financial statements of the U.S. government (CFS) due primarily to certain material weaknesses in the federal government's internal control. GAO has reported that unless these weaknesses are adequately addressed, they will, among other things, (1) hamper the federal government's ability to reliably report a significant portion of its assets, liabilities, costs, and other related information; and (2) affect the federal government's ability to reliably measure the full cost as well as the financial and nonfinancial performance of certain programs and activities. This testimony presents the results of GAO's audit of the CFS for fiscal year 2007 and discusses the federal government's long-term fiscal outlook."

Testimony issued by the Government Accountability Office with an abstract that begins "For decades, the nation has benefited from relatively inexpensive energy, in the process growing heavily reliant on conventional fossil fuels--oil, natural gas, and coal. However, in the current wake of higher energy costs and environmental concerns about fossil fuel emissions, renewed attention is turning to the development of advanced energy technologies as alternatives. In the United States, the Department of Energy (DOE) has long conducted research, development, and demonstration (R&D) on advanced renewable, fossil, and nuclear energy technologies. DOE's Office of Science has also funded basic energy-related research. This testimony addresses (1) funding trends for DOE's renewable, fossil, and nuclear energy R&D programs and its Office of Science and (2) key challenges in developing and deploying advanced energy technologies. It is based on GAO's December 2006 report entitled Department of Energy: Key Challenges Remain for Developing and Deploying Advanced Energy Technologies to Meet Future Needs (GAO-07-106). In doing that work, GAO reviewed DOE's R&D budget data and strategic plans and obtained the views of experts in DOE, industry, and academia, as well as state and foreign government officials."

Correspondence issued by the Government Accountability Office with an abstract that begins "This letter formally transmits the briefing in response to the explanatory statement accompanying the Department of Homeland Security Appropriations Act, 2008 (Public Law 110-161, Division E). The statement directed the Comptroller General to report on its assessment of the Transportation Security Administration's (TSA) report to the Committees on Appropriations of the Senate and House of Representatives on the anticipated security benefits and vulnerabilities associated with TSA's decision to suspend enforcement of the prohibition on butane lighters onboard aircraft."

A letter report issued by the Government Accountability Office with an abstract that begins "The 2005 Base Closure and Realignment Commission estimated that two supply-related recommendations now being implemented by the Defense Logistics Agency (DLA) would save the Department of Defense (DOD) about $4.8 billion over 20 years--about 13 percent of the 2005 base realignment and closure (BRAC) round's estimated long-term savings. These recommendations focus on business process reengineering by reconfiguring DLA's wholesale supply, storage, and distribution network and transferring procurement responsibility for depot-level reparables from the military services to DLA. This report is one in a series of reports on BRAC conducted under the Comptroller General's authority. It examines (1) the extent to which DLA's cost and savings estimates to implement these recommendations differ from those of the BRAC Commission and (2) DLA's progress and challenges in implementing the recommendations. GAO analyzed estimated cost and savings data and visited several of the military services' depots in its review."

A letter report issued by the Government Accountability Office with an abstract that begins "This report presents our opinion on the financial statements of the Capitol Preservation Fund (the Fund) for the fiscal years ended September 30, 2007, and 2006. It also discusses our consideration of the Fund's internal controls and our tests of compliance with laws and regulations during fiscal years 2007 and 2006. We conducted our audits pursuant to 2 U.S.C. 2084 and in accordance with U.S. generally accepted government auditing standards. We appreciate the cooperation and assistance of the Office of the Secretary of the Senate, the Office of the Clerk of the House of Representatives, and the staff of the Library of Congress during our audits."

This report contains an explanation of the major provisions of the federal estate, gift, and generation-skipping transfer taxes. The discussion divides the federal estate tax into three components: the gross estate, deductions from the gross estate, and computation of the tax, including allowable tax credits. The federal estate tax is computed through a series of adjustments and modifications of a tax base known as the "gross estate." Certain allowable deductions reduce the gross estate to the "taxable estate," to which is then added the total of all lifetime taxable gifts made by the decedent. The tax rates are applied and, after reduction for certain allowable credits, the amount of tax owed by the estate is reached.

Recent reports have shown that, despite efforts to the contrary, chemical accidents continue to occur at an unacceptable rate and there is no evidence that this rate is decreasing. Based on this observation, one can conclude that previous analyses have not accurately identified and implemented appropriate fixes to eliminate identified root causes for chemical events. Based on this, it is time to reevaluate chemical accident data with a fresh eye and determine (a) what corrective actions have already been identified but have not been implemented, (b) what other root causes may be involved, and (c) what new corrective actions should be taken to eliminate these newly identified root causes.

When direct reactions populate highly excited, unbound configurations in the residual nucleus, the nucleus may further evolve into a compound nucleus. Alternatively, the residual system may decay by emitting particles into the continuum. Understanding the relative weights of these two processes as a function of the angular momentum and parity deposited in the nucleus is important for the surrogate-reaction technique. A particularly interesting case is compound-nucleus formation via the (d, p) reaction, which may be a useful tool for forming compound nuclei off the valley of stability in inverse-kinematics experiments. We present here a study of the compound formation probability for a closely-related direct reaction, direct-semidirect radiative neutron capture.

Yucca Mountain (YM), Nevada, has been proposed by the U.S. Department of Energy as a geologic repository for spent nuclear fuel and high-level radioactive waste. In this study, we investigate the potential for groundwater advective pathways from underground nuclear testing areas on the Nevada Test Site (NTS) to the YM area by estimating the timeframe for advective travel and its uncertainty resulting from porosity value uncertainty for hydrogeologic units (HGUs) in the region. We perform sensitivity analysis to determine the most influential HGUs on advective radionuclide travel times from the NTS to the YM area. Groundwater pathways and advective travel times are obtained using the particle tracking package MODPATH and flow results from the Death Valley Regional Flow System (DVRFS) model by the U.S. Geological Survey. Values and uncertainties of HGU porosities are quantified through evaluation of existing site porosity data and expert professional judgment and are incorporated through Monte Carlo simulations to estimate mean travel times and uncertainties. We base our simulations on two steady state flow scenarios for the purpose of long term prediction and monitoring. The first represents pre-pumping conditions prior to groundwater development in the area in 1912 (the initial stress period of the DVRFS model). …

The candidate division Korarchaeota comprises a group of uncultivated microorganisms that, by their small subunit rRNA phylogeny, may have diverged early from the major archaeal phyla Crenarchaeota and Euryarchaeota. Here, we report the initial characterization of a member of the Korarchaeota with the proposed name,"Candidatus Korarchaeum cryptofilum," which exhibits an ultrathin filamentous morphology. To investigate possible ancestral relationships between deep-branching Korarchaeota and other phyla, we used whole-genome shotgun sequencing to construct a complete composite korarchaeal genome from enriched cells. The genome was assembled into a single contig 1.59 Mb in length with a G + C content of 49percent. Of the 1,617 predicted protein-coding genes, 1,382 (85percent) could be assigned to a revised set of archaeal Clusters of Orthologous Groups (COGs). The predicted gene functions suggest that the organism relies on a simple mode of peptide fermentation for carbon and energy and lacks the ability to synthesize de novo purines, CoA, and several other cofactors. Phylogenetic analyses based on conserved single genes and concatenated protein sequences positioned the korarchaeote as a deep archaeal lineage with an apparent affinity to the Crenarchaeota. However, the predicted gene content revealed that several conserved cellular systems, such as cell division, DNA replication, and tRNA …

Nonlinear optics plays a central role in the advancement of optical science and laser-based technologies. We report on the confinement of the nonlinear interaction of light with matter to a single wave cycle and demonstrate its utility for time-resolved and strong-field science. The electric field of 3.3-femtosecond, 0.72-micron laser pulses with a controlled and measured waveform ionizes atoms near the crests of the central wave cycle, with ionization being virtually switched off outside this interval. Isolated sub-100-attosecond pulses of extreme ultraviolet light (photon energy {approx} 80 electron volts), containing {approx} 0.5 nanojoule of energy, emerge from the interaction with a conversion efficiency of {approx} 10{sup -6}. These tools enable the study of the precision control of electron motion with light fields and electron-electron interactions with a resolution approaching the atomic unit of time ({approx} 24 attoseconds).

The results of a review and evaluation of neutron and non-neutron nuclear data published in the scientific literature are presented. The status of new chemical elements is examined. Data on revised values for the isotopic composition of the elements are reviewed and recommended values are presented. Half-lives of very long-lived nuclides are presented, including double beta decay, double electron capture, long-lived alpha decay and long-lived beta decay. Data from new measurements on the very heavy elements (trans-meitnerium elements) are discussed and tabulated. The first observation of the radioactive decay mode of the free neutron is discussed. New measurements that have expanded the neutron drip line for magnesium and aluminum are discussed. Data on recent neutron cross-section and resonance integral measurements are also discussed.
