U.S. Coins: The Federal Reserve Banks Are Fulfilling Coin Demand, but Optimal Inventory Ranges Are Undefined (open access)

U.S. Coins: The Federal Reserve Banks Are Fulfilling Coin Demand, but Optimal Inventory Ranges Are Undefined

A letter report issued by the Government Accountability Office with an abstract that begins "Federal Reserve Banks fulfill the coin demand of the nation's depository institutions--which include commercial banks, savings and loan associations, and credit unions--by ordering new coins from the U.S. Mint and managing coins held in inventory at the Reserve Banks and in coin terminals. Reliably estimating the demand for coins and efficiently managing the inventory of circulated coins is important to ensure that depository institutions have enough coins to meet the public's demand and to avoid unnecessary coin production costs. Since late 2006, rising metal prices have driven the costs of producing pennies and nickels above the face values of the coins. This report addresses (1) the Reserve Banks' process for ordering and distributing coins to the nation's depository institutions and (2) the extent to which this process meets depository institutions' demand for coins. GAO interviewed officials responsible for coin distribution at each of the 12 Reserve Banks and met with representatives of 4 large operators of Federal Reserve coin terminals, 2 banking associations, the U.S. Mint, and the nation's largest coin recycling company. GAO also analyzed Reserve Bank data for fiscal years 1993 through 2007. Federal …

Tobacco Settlement: States' Allocations of Fiscal Year 2004 and Expected Fiscal Year 2005 Payments (open access)

Tobacco Settlement: States' Allocations of Fiscal Year 2004 and Expected Fiscal Year 2005 Payments

A letter report issued by the Government Accountability Office with an abstract that begins "In the 1990s, states sued major tobacco companies to obtain reimbursement for health impairments caused by the public's use of tobacco. In 1998, 46 states and four of the nation's largest tobacco companies signed a Master Settlement Agreement (MSA) that requires the tobacco companies to make annual payments to the states in perpetuity as reimbursement for past tobacco-related health care costs. The MSA commits the tobacco companies to pay the states approximately $206 billion over the first 25 years. Some of the states have arranged to receive upfront proceeds based on the amounts that tobacco companies owe by issuing bonds backed by future payments. The Farm Security and Rural Investment Act of 2002 requires GAO to report annually on the amount of MSA payments that states receive through fiscal year 2006. This fourth report provides information on (1) the payments the 46 states received in fiscal year 2004 and expect to receive in fiscal year 2005 and (2) states' allocations of these funds to various program categories and changes from prior years. To conduct this study, GAO surveyed the 46 states."

The Nation's Long-Term Fiscal Outlook: January 2008 Update (open access)

The Nation's Long-Term Fiscal Outlook: January 2008 Update

Correspondence issued by the Government Accountability Office with an abstract that begins "Since 1992, GAO has published long-term fiscal simulations of what might happen to federal deficits and debt levels under varying policy assumptions. We developed our long-term model in response to a bipartisan request from Members of Congress who were concerned about the long-term effects of fiscal policy. Our simulations were updated with Congressional Budget Office (CBO's) January budget and economic projections and continue to indicate that the long-term federal fiscal outlook remains unsustainable. This update combined with our analysis of the fiscal outlook of state and local governments demonstrates that the fiscal challenges facing all levels of government are linked and should be considered in a strategic and integrated manner. We update our simulations three times a year as new estimates become available from CBO's Budget and Economic Outlook (January), Social Security and Medicare Trustees Reports (spring), and CBO's Budget and Economic Outlook: An Update (late summer). This product responds to congressional interest in receiving updated simulation results."

VA Health Care: VA Should Better Monitor Implementation and Impact of Capital Asset Alignment Decisions (open access)

VA Health Care: VA Should Better Monitor Implementation and Impact of Capital Asset Alignment Decisions

A letter report issued by the Government Accountability Office with an abstract that begins "Through its Veterans Health Administration (VHA), the Department of Veterans Affairs (VA) operates one of the largest health care systems in the country. In 1999, GAO reported that better management of VA's large inventory of aged capital assets could result in savings that could be used to enhance health care services for veterans. In response, VA initiated a process known as Capital Asset Realignment for Enhanced Services (CARES). Through CARES, VA sought to enhance veteran care by the appropriate sizing, upgrading, and locating of VA facilities. GAO was asked to examine the CARES process. Specifically, GAO examined (1) how CARES contributes to VHA's capital planning process, (2) the extent to which the CARES process considered capital asset alignment alternatives, and (3) the extent to which VA has implemented CARES decisions and how this implementation has helped VA carry out its mission. To address these issues, we analyzed CARES documents, interviewed VA officials, and conducted six site visits, among other things."

Low-Level Radioactive Waste Management: Approaches Used by Foreign Countries May Provide Useful Lessons for Managing U.S. Radioactive Waste (open access)

Low-Level Radioactive Waste Management: Approaches Used by Foreign Countries May Provide Useful Lessons for Managing U.S. Radioactive Waste

A letter report issued by the Government Accountability Office with an abstract that begins "GAO has reported on limitations in the management of U.S. low-level radioactive waste (LLRW). LLRW ranges from very low-activity to higher-activity waste. To identify potential approaches to overcome these limitations, GAO was asked to examine the extent to which other countries have (1) LLRW inventory databases, (2) timely removal of higher-activity LLRW from waste generator sites, (3) disposition options for all LLRW, and (4) requirements that LLRW generators have financial reserves to cover waste disposition costs, as well as any other approaches that might improve U.S. LLRW management. GAO primarily relied on a survey of 18 countries representing leading LLRW generators to identify their management approaches and to compare them with U.S. survey results and with approaches suggested by LLRW generators, disposal operators, and regulators in the United States."

Defense Logistics: High-Level DOD Coordination Is Needed to Further Improve the Management of the Army's LOGCAP Contract

A letter report issued by the Government Accountability Office with an abstract that begins "The Logistics Civil Augmentation Program (LOGCAP) is an Army program that plans for the use of a private-sector contractor to support worldwide contingency operations. Examples of the types of support available include laundry and bath, food service, sanitation, billeting, maintenance, and power generation. LOGCAP has been used extensively to support U.S. forces in recent operations in southwest Asia, with more than $15 billion in estimated work as of January 2005. While we issued two reports on LOGCAP since 1997 that made recommendations to improve the Army's management of the contract, broader issues on coordination of LOGCAP's contract functions were beyond the scope of our earlier work. This report assesses the extent to which the Army is taking action to improve the management and oversight of LOGCAP and whether further opportunities for using this contract effectively exist."

Federal Aviation Administration: Observations on Selected Changes to FAA's Funding and Budget Structure in the Administration's Reauthorization Proposal

Testimony issued by the Government Accountability Office with an abstract that begins "Recently, the administration submitted a proposal for reauthorizing the Federal Aviation Administration (FAA) and the excise taxes that fund most of its budget. FAA's current authorization expires in 6 months. The proposal calls for major changes to FAA's funding and budget structure that are intended to address concerns about the long-term revenue adequacy, equity, and efficiency of FAA's current funding structure and to provide a more stable, reliable basis for funding a new air traffic control system that FAA is developing (at an estimated cost of $15 billion to 22 billion through 2025) to meet forecasted increases in air travel demand. The proposal would introduce cost-based charges for commercial users of air traffic control services, eliminate many current taxes, substantially raise fuel taxes for general aviation users, charge commercial and general aviation users a fuel tax to pay primarily for airport capital improvements, modify FAA's budget accounts to align with specific FAA activities, and link the portion of FAA's budget that comes from the Treasury's General Fund with public benefits FAA provides. This statement offers GAO's observations on the proposed changes in FAA's (1) funding and (2) budget …

Information Technology: OMB Leadership Critical to Making Needed Enterprise Architecture and E-government Progress

Testimony issued by the General Accounting Office with an abstract that begins "E-government refers to operations that enhance delivery of government information and services. Enterprise architectures provides for successful delivery of e-government applications, which in turn promise improved government performance and accountability. Under the Office of Management and Budget's (OMB) leadership, the president's fiscal year 2003 budget proposes 24 e-government initiatives, most involving multiple agencies. These initiatives have laudable goals, including the elimination of redundant, nonintegrated business operations and systems which could save billions of dollars. The success of these initiatives depends in large part on whether they are pursued within the context of enterprise architectures. Approved architectures for most of these initiatives do not currently exist. OMB has been a proponent of enterprise architectures and has recently devoted increased attention to them. However, it can and should play a larger role. The maturity framework and benchmark data about 116 departments, component agencies, and independent agencies GAO reviews in this testimony provide important baseline information against which targeted improvement across the government can be defined and measured."

Foreign Assistance: U.S. Agencies Face Challenges to Improving the Efficiency and Effectiveness of Food Aid (open access)

Foreign Assistance: U.S. Agencies Face Challenges to Improving the Efficiency and Effectiveness of Food Aid

Testimony issued by the Government Accountability Office with an abstract that begins "The United States is the largest provider of food aid in the world, accounting for over half of all global food aid supplies intended to alleviate hunger. Since the 2002 reauthorization of the Farm Bill, Congress has appropriated an average of $2 billion per year for U.S. food aid programs, which delivered an average of 4 million metric tons of agricultural commodities per year. Despite growing demand for food aid, rising business and transportation costs have contributed to a 43-percent decline in average tonnages delivered over the last 5 years. For the largest U.S. food aid program, these costs represent approximately 65 percent of total food aid expenditures, highlighting the need to maximize the efficiency and effectiveness of food aid. To inform Congress as it reauthorizes the 2007 Farm Bill, GAO examined some key challenges to the (1) efficiency of delivery and (2) effective monitoring of U.S. food aid."

Retirement Income Data: Improvements Could Better Support Analysis of Future Retirees' Prospects

A letter report issued by the General Accounting Office with an abstract that begins "Future demographic trends include a doubling of the nation's retiree population and only modest labor force growth, leading to concerns about retirement income adequacy for future generations. Credible projections of the effects of policy proposals on federal spending and future retirees' income are necessary. Because adequate data is critical to the analysis of retirement income and wealth, GAO was asked to identify data improvements that experts say are a priority for the study of retirement income and wealth, as well as factors limiting efforts to obtain the needed information."

FAA Purchase Cards: Weak Controls Resulted in Instances of Improper and Wasteful Purchases and Missing Assets

A letter report issued by the General Accounting Office with an abstract that begins "In May 2002, GAO reported on breakdowns in purchasing controls at the Federal Aviation Administration's (FAA) Alaskan Region that resulted in improper and wasteful purchases. Many of the weaknesses were associated with the use of government credit cards--referred to as purchase cards--and raised concerns that similar problems might exist FAA-wide. As a result, GAO was asked to determine whether FAA's purchase card controls reasonably ensured that purchases were proper, at a reasonable cost, and for valid government needs. GAO also assessed whether assets bought with purchase cards were being properly safeguarded and recorded."

Long-Term Care: Aging Baby Boom Generation Will Increase Demand and Burden on Federal and State Budgets (open access)

Long-Term Care: Aging Baby Boom Generation Will Increase Demand and Burden on Federal and State Budgets

Testimony issued by the General Accounting Office with an abstract that begins "As more and more of the baby boomers enter retirement age, spending for Medicare, Medicaid, and Social Security is expected to absorb correspondingly larger shares of federal revenue and crowd out other spending. The aging of the baby boomers will also increase the demand for long-term care and contribute to federal and state budget burdens. The number of disabled elderly who cannot perform daily living activities without assistance is expected to double in the future. Long-term care spending from public and private sources--about $137 billion for persons of all ages in 2000--will rise dramatically as the baby boomers age. Without fundamental financing changes, Medicaid--which pays more than one-third of long-term care expenditures for the elderly--can be expected to remain one of the largest funding sources, straining both federal and state governments."

Environmental Protection: Observations on Elevating the Environmental Protection Agency to Cabinet Status

Testimony issued by the General Accounting Office with an abstract that begins "This testimony comments on legislation that would elevate the Environmental Protection Agency (EPA) to Cabinet status. Today, EPA's mission, size, and scope of responsibilities place it on a par with many Cabinet departments. The United States is the only major industrial power without a Cabinet-level environmental organization. It is important to consider that (1) environmental policy be given appropriate weight as it cuts across the domestic and foreign policies that other Cabinet departments implement and enforce and (2) the head of the agency is able to deal as an equal with his or her counterparts within the federal government as well as the international community. Conferring Cabinet status on EPA would not in itself change the federal environmental role or policies, but it would clearly have an important symbolic effect. Regardless of its status, however, EPA must respond more effectively to its fundamental management challenges. These challenges include (1) placing the right people with the appropriate skills where they are needed and (2) gaining access to high-quality environmental, natural, and social data on which to base environmental decisions. EPA must have the flexibility to use innovative approaches to …

Intercity Passenger Rail: Assessing the Benefits of Increased Federal Funding for Amtrak and High-Speed Passenger Rail Systems (open access)

Intercity Passenger Rail: Assessing the Benefits of Increased Federal Funding for Amtrak and High-Speed Passenger Rail Systems

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the benefits of increased federal funding for the National Railroad Passenger Corporation (Amtrak) and high-speed passenger rail systems. Amtrak made minimal progress in 2000 toward achieving operational self-sufficiency. Although Amtrak is required by law to achieve operational self-sufficiency by the end of 2002, the outlook is not bright. Amtrak reduced its "budget gap" by only $5 million and must achieve an additional $281 million in savings by the end of next year. In addition to the uncertainty over Amtrak's future, this is an opportunity to examine the future of intercity passenger rail. Federal costs are expected to be large. For example, the ultimate cost to build high-speed rail corridors is unknown, but it will certainly be in the many tens of billions of dollars. Much of the funding could be expected to come from the federal government. In deciding the future of intercity passenger rail, it is important for Congress to have realistic assessments of the benefits to the public from this mode of transportation. These assessments would help establish the role, if any, of intercity passenger rail service in the nation's transportation system and …

Foreign Assistance: Implementing Disaster Recovery Assistance in Latin America

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the U.S. government's disaster recovery and reconstruction program for countries that have been devastated by hurricanes. GAO found that the Agency for International Development (AID) and other U.S. agencies are using the disaster recovery assistance to bring about economic recovery, improve public health and access to education, provide permanent housing for displaced families, and improve disaster mitigation and preparedness. To achieve these broad objectives, AID is funding infrastructure construction and repair, technical assistance and training, loans for farmers and small businesses, and some commodities. After initial start-up problems, the U.S. disaster recovery and reconstruction program is proceeding, and most activities are scheduled for completion on or before December 31, 2001, as AID and congressional staff had informally agreed. To help ensure that funds are spent as intended, AID has channeled much of the disaster recovery assistance funding through cooperating partners with proven track records, contracted with management and financial services firms to handle disbursement to vulnerable partners, and hired contractors to monitor project quality. Although some activities have not gone as smoothly as planned, the missions have responded to concerns as they arose. The bottom …

Testimony issued by the Government Accountability Office with an abstract that begins "Advances in information technology make it easier than ever for the Department of Homeland Security (DHS) and other agencies to obtain and process information about citizens and residents in many ways and for many purposes. The demands of the war on terror also drive agencies to extract as much value as possible from the information available to them, adding to the potential for compromising privacy. Recognizing that securing the homeland and protecting the privacy rights of individuals are both important goals, the Congress has asked GAO to perform several reviews of DHS programs and their privacy implications over the past several years. For this hearing, GAO was asked to testify on key privacy challenges facing DHS. To address this issue, GAO identified and summarized issues raised in its previous reports on privacy and assessed recent governmentwide privacy guidance."

End-Of-Life Vehicle Recycling: State of the Art of Resource Recovery From Shredder Residue. (open access)

End-Of-Life Vehicle Recycling: State of the Art of Resource Recovery From Shredder Residue.

Each year, more than 50 million vehicles reach the end of their service life throughout the world. More than 95% of these vehicles enter a comprehensive recycling infrastructure that includes auto parts recyclers/dismantlers, remanufacturers, and material recyclers (shredders). Today, about 75% of automotive materials are profitably recycled via (1) parts reuse and parts and components remanufacturing and (2) ultimately by the scrap processing (shredding) industry. The process by which the scrap processors recover metal scrap from automobiles involves shredding the obsolete automobiles, along with other obsolete metal-containing products (such as white goods, industrial scrap, and demolition debris), and recovering the metals from the shredded material. The single largest source of recycled ferrous scrap for the iron and steel industry is obsolete automobiles. The non-metallic fraction that remains after the metals are recovered from the shredded materials (about 25% of the weight of the vehicle)--commonly called shredder residue--is disposed of in landfills. Over the past 10 to 15 years, a significant amount of research and development has been undertaken to enhance the recycle rate of end-of-life vehicles (ELVs), including enhancing dismantling techniques and improving remanufacturing operations. However, most of the effort has focused on developing technology to recover materials, such as …

Center-stabilized Yang-Mills Theory:Confinement and Large N Volume Independence (open access)

Center-stabilized Yang-Mills Theory:Confinement and Large N Volume Independence

We examine a double trace deformation of SU(N) Yang-Mills theory which, for large N and large volume, is equivalent to unmodified Yang-Mills theory up to O(1/N{sup 2}) corrections. In contrast to the unmodified theory, large N volume independence is valid in the deformed theory down to arbitrarily small volumes. The double trace deformation prevents the spontaneous breaking of center symmetry which would otherwise disrupt large N volume independence in small volumes. For small values of N, if the theory is formulated on R{sup 3} x S{sup 1} with a sufficiently small compactification size L, then an analytic treatment of the non-perturbative dynamics of the deformed theory is possible. In this regime, we show that the deformed Yang-Mills theory has a mass gap and exhibits linear confinement. Increasing the circumference L or number of colors N decreases the separation of scales on which the analytic treatment relies. However, there are no order parameters which distinguish the small and large radius regimes. Consequently, for small N the deformed theory provides a novel example of a locally four-dimensional pure gauge theory in which one has analytic control over confinement, while for large N it provides a simple fully reduced model for Yang-Mills theory. …

SOLVING THE STAND-OFF PROBLEM FOR MAGNETIZED TARGET FUSION: PLASMA STREAMS AS DISPOSABLE ELECTRODES, PLUS A LOCAL SPHERICAL BLANKET

In a fusion reactor based on the Magnetized Target Fusion approach, the permanent power supply has to deliver currents up to a few mega-amperes to the target dropped into the reaction chamber. All the structures situated around the target will be destroyed after every pulse and have to be replaced at a frequency of 1 to 10 Hz. In this paper, an approach based on the use of spherical blanket surrounding the target, and pulsed plasma electrodes connecting the target to the power supply, is discussed. A brief physic analysis of the processes associated with creation of plasma electrodes is discussed.
