D/sup -/ production by multiple charge-transfer collisions of low-energy D ions and atoms in cesium vapor
The production of D/sup -/ by multiple charge-transfer collisions of a D/sup +/ beam in a cesium-vapor target is considered for D/sup +/ energies above 300 eV. The cross sections relevant to D/sup -/ formation are obtained by a least-squares fit of three-charge-state differential equations to experimental yield curves. Implications for production of intense negative-ion beams are discussed, and speculations are made about extrapolation to lower engeries.

Estimating Adipose Tissue in the Chest Wall Using Ultrasonic and Alternate /sup 40/K and Biometric Measurements
The percentage of adipose (fat) tissue in the chest wall must be known to accurately measure Pu in the human lung. Correction factors of 100% or more in x-ray detection efficiency are common. Methods using simple /sup 40/K and biometric measurement techniques were investigated to determine the adipose content in the human chest wall. These methods predict adipose content to within 15% of the absolute ultrasonic value. These new methods are discussed and compared with conventional ultrasonic measurement techniques. (ERB)

Combustion Research Program: Flame studies, laser diagnostics, and chemical kinetics
We have made a detailed study of the care that must be taken to correctly measure OH radical concentrations in flames. A large part of these studies has concerned collisional quenching of hydride radical species (OH, NH, and NH{sub 2}), in particular the dependence upon rotational level and collision velocity (temperature). The results on OH and NH have shown unique and interesting behavior from the viewpoint of fundamental molecular dynamics, pointing to quenching often governed by collisions on an anisotropic, attractive surface, whereas NH{sub 2} quenching appears to depend on state-mixing considerations, not dynamic control. This state-specific behavior of these small, theoretically tractable hydrides has direct ramifications for quantitative flame diagnostics. Our other effort in the diagnostic area has been repeated but unsuccessful searches for laser induced fluorescence in the vinyl radical.

Medicare Part D: Plan Sponsors' Processing and CMS Monitoring of Drug Coverage Requests Could Be Improved
A letter report issued by the Government Accountability Office with an abstract that begins "Under the Medicare Part D program, prescription drug coverage is provided through plans sponsored by private companies. Beneficiaries, their appointed representatives, or physicians can ask sponsors to cover prescriptions restricted under their plan--a process known as a coverage determination--and can appeal denials to the sponsor and the independent review entity (IRE). GAO was asked to review (1) the processes for sponsors' coverage determination decisions and the approval rates, (2) the processes for appealing coverage denials and the approval rates at the sponsor and IRE levels, and (3) the Centers for Medicare & Medicaid Services' (CMS) efforts to inform the public about sponsors' performance and oversee sponsors' processes. GAO visited seven sponsors that account for over half of Part D enrollment. GAO also interviewed and obtained data from CMS and IRE officials."

Forest Service: Better Planning, Guidance, and Data Are Needed to Improve Management of the Competitive Sourcing Program
A letter report issued by the Government Accountability Office with an abstract that begins "Competitive sourcing is aimed at promoting competition between federal employees and the private sector as a way to improve government operations. Key work activities--those that are either inherently governmental or core to the agency's mission--are generally exempt from competitions. In fiscal year 2004, Congress began placing spending limitations on the Forest Service's competitive sourcing program because of concerns about how the program was managed. Also, like other agencies, the Forest Service must report annually to Congress on the savings achieved from any competitions it conducted. GAO was asked to determine the extent to which the Forest Service has (1) plans and guidance to help implement its competitive sourcing program effectively and (2) sufficient cost data to ensure that it complied with its spending limitations and accurately reported its savings to Congress for fiscal years 2004 through 2006. To answer these objectives, GAO examined the agency's strategic plan, guidance, and available cost data for competitive sourcing and interviewed key agency officials."

Defense Logistics: The Army Needs to Implement an Effective Management and Oversight Plan for the Equipment Maintenance Contract in Kuwait
Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) relies on contractors to perform many of the functions needed to support troops in deployed locations. For example, at Camp Arifjan, Kuwait the Army uses contractors to provide logistics support for operations in Iraq and Afghanistan. Contractors at Camp Arifjan refurbish and repair a variety of military vehicles such as the Bradley Fighting Vehicle, armored personnel carriers, and the High-Mobility, Multi-Purpose Wheeled Vehicle (HMMWV). However, while contractors provide valuable support to deployed forces, we have frequently reported that long-standing DOD contract management and oversight problems increase the opportunity for waste and make it more difficult for DOD to ensure that contractors are meeting contract requirements efficiently, effectively, and at a reasonable price. This report discusses information about Task Order 1 that we developed during our review. Our objectives were to (1) evaluate the contractor's performance of maintenance and supply services under Task Order 1, (2) determine the extent to which the Army's quality assurance and contract management activities implement key principles of quality assurance and contract management regulations and guidance, and (3) determine the extent to which the Army is adequately staffed to …

Embassy Construction: Better Long-term Planning Will Enhance Program Decision-making
A letter report issued by the General Accounting Office with an abstract that begins "The State Department has determined that about 80 percent of overseas U.S. diplomatic facilities lack adequate security and may be vulnerable to terrorist attack. In September 1998, State expanded its capital construction program to accelerate replacing its most vulnerable embassies and consulates by acquiring sites and preparing plans at 10 priority locations. This report summarizes (1) the status of the 10 priority embassy and consulate construction projects and (2) State's plans for the overall construction program. As of November 2000, seven projects are in the construction phase. The remaining three projects are on hold pending agreement between State and Congress about the Department's construction proposals. Although State envisions a long-term, multi-billion dollar program and has ranked more than 180 facilities it may need to replace, it has not prepared a long-term capital construction plan that identifies (1) proposed construction project's cost estimates and schedules and (2) estimated annual funding requirements for the overall program."

High-Risk Series: An Update
A letter report issued by the Government Accountability Office with an abstract that begins "The federal government is the world's largest and most complex entity, with about $3 trillion in outlays in fiscal year 2008 funding a broad array of programs and operations. GAO's biennial reports on high-risk areas, done since 1990, are meant to bring focus to specific areas needing added attention. Areas are identified, in some cases, as high risk due to their greater vulnerabilities to fraud, waste, abuse, and mismanagement. GAO also identifies high-risk areas needing broad-based transformation to address major economy, efficiency, or effectiveness challenges. In this 2009 update for the 111th Congress, GAO presents the status of high-risk areas listed in 2007 and identifies new high-risk areas warranting attention by Congress and the executive branch. Solutions to high-risk problems offer the potential to save billions of dollars, dramatically improve service to the public, strengthen confidence and trust in the performance and accountability of the U.S. government, and ensure the ability of government to deliver on its promises."

Broadcasting to Cuba: Actions Are Needed to Improve Strategy and Operations
A letter report issued by the Government Accountability Office with an abstract that begins "For more than two decades, the U.S. government has been broadcasting to Cuba to break the Cuban government's information blockade and promote democracy in Cuba. Over this period, questions have been raised regarding the quality and effectiveness of these broadcasts. GAO was asked to examine (1) the Office of Cuba Broadcasting's (OCB) broadcasting approach and what is known about its audience; (2) how the Broadcasting Board of Governors (BBG)--which oversees U.S. government broadcasting--and OCB ensure compliance with journalistic principles; (3) steps taken to ensure adherence to domestic and international broadcasting laws, agreements, and standards; and (4) steps BBG and OCB have taken to address management challenges. GAO analyzed documentation related to strategic planning, audience research, oversight, and operations and interviewed officials from BBG, BBG's International Broadcasting Bureau (IBB), OCB, State, and other agencies."

Pension Costs on DOD Contracts: Additional Guidance Needed to Ensure Costs Are Consistent and Reasonable
A letter report issued by the Government Accountability Office with an abstract that begins "Labor costs are included in the prices contractors negotiate with the Department of Defense (DOD), and include pension costs as these are a normal element of employee compensation. Contractors make two sets of calculations for their defined benefit pension plans, following two sets of standards: (1) Cost Accounting Standards (CAS), which determine how pension costs are allocated to government contracts; and (2) Employee Retirement Income Security Act of 1974 (ERISA), which establishes the minimum contribution required to fund plans. In 2008, revised ERISA rules altered the minimum funding requirements, causing CAS costs and ERISA contributions to diverge further apart. ERISA contributions have therefore greatly exceeded CAS pension costs reflected in contract prices. In December 2011, almost 4 years after ERISA changes took effect, the CAS Board, which is part of the Office of Management and Budget (OMB), made changes to CAS that harmonized them to ERISA in order to gradually reduce the difference between the two calculation methods."

Social Security Numbers: Private Sector Entities Routinely Obtain and Use SSNs, and Laws Limit the Disclosure of This Information
A letter report issued by the General Accounting Office with an abstract that begins "In 1936, the Social Security Administration (SSA) established the Social Security number (SSN) to track workers' earnings for Social Security benefit purposes. However, the SSN is also used for a myriad of non-Social Security purposes. Today, public and private sector entities view the SSN as a key piece of information that enables them to conduct their business and deliver services. However, given the apparent rise in identity crimes as well as the rapidly increasing availability of information over the Internet, Congress has raised concern over how certain private sector entities obtain, use, and safeguard SSN data. In previous reports, we discussed the benefits of government and commercial entities using SSNs. We also examined how certain private sector entities and the government obtain, use, and safeguard SSNs. This report provides additional information on private sector uses of SSNs. The Chairman, Subcommittee on Social Security, House Committee on Ways and Means, asked that GAO examine the private sector use of SSNs by businesses most likely to obtain and use them including information resellers, consumer reporting agencies (CRAs), and health care organizations. Specifically, our objectives were to (1) describe …

Border Security: Better Usage of Electronic Passport Security Features Could Improve Fraud Detection
A letter report issued by the Government Accountability Office with an abstract that begins "In 2005, the Department of State (State) began issuing electronic passports (e-passports) with embedded computer chips that store information identical to that printed in the passport. By agreement with State, the U.S. Government Printing Office (GPO) produces blank e-passport books. Two foreign companies are used by GPO to produce e-passport covers, including the computer chips embedded in them. At U.S. ports of entry, the Department of Homeland Security (DHS) inspects passports. GAO was asked to examine potential risks to national security posed by using foreign suppliers for U.S. e-passport computer chips. This report specifically examines the following two risks: (1) Can the computer chips used in U.S. e-passports be altered or forged to fraudulently enter the United States? (2) What risk could malicious code on the U.S. e-passport computer chip pose to national security? To conduct this work, GAO reviewed documents and interviewed officials at State, GPO, and DHS relating to the U.S. e-passport design and manufacturing and e-passport inspection systems and procedures."

State and Local Governments: Growing Fiscal Challenges Will Emerge during the Next 10 Years
A letter report issued by the Government Accountability Office with an abstract that begins "State and local governments provide an array of services to their residents, such as primary and secondary education, libraries, police and fire services, social programs, roads and other infrastructure, public colleges and universities, and more. These subnational governments may face fiscal stress similar to the federal government. Given the nature of the partnership among levels of government in providing services to Americans and the economic interrelationships among levels of government, understanding potential future fiscal conditions of the state and local government sector is important for federal policymaking. To provide Congress and the public with this broader context, we developed a fiscal model of the state and local sector. This report describes this model and provides (1) simulations of the state and local government sector's long-term fiscal outlook, (2) an analysis of the underlying causes of potential fiscal difficulties for the sector, (3) a discussion of the extent to which the long-term simulations are sensitive to alternative assumptions, and (4) an examination of how the state and local government sector could add to future federal fiscal challenges. The potential fiscal outcomes of the state and local government …

Real Property: Infrastructure Investment Presents Opportunities to Address Long-standing Real Property Backlogs and Reduce Energy Consumption
Testimony issued by the Government Accountability Office with an abstract that begins "Federal agencies have identified billions of dollars in reinvestment requirements to maintain their aging facilities and bring them up to current standards. In addition, according to Department of Energy (DOE) estimates, federal agencies will need over a billion dollars annually through 2015 for projects needed to meet congressional energy efficiency goals. As the nation's single largest energy consumer, the federal government spent approximately $17 billion in fiscal year 2007 on energy use in buildings and vehicles. This total represents almost 1 percent of all federal expenditures for 2007, and these costs have risen in recent years. This testimony discusses the potential benefits that may accrue from infrastructure investment, including energy reductions within federal buildings, and principles that could help guide infrastructure investment. Our comments are based on our body of work on repair and maintenance and energy management issues associated with federal real property."

Depot Maintenance: Key Financial Issues for Consolidations at Pearl Harbor and Elsewhere Are Still Unresolved
A chapter report issued by the General Accounting Office with an abstract that begins "In 1998, the Navy consolidated the Pearl Harbor Naval Shipyard and the Naval Intermediate Maintenance Facility in Hawaii. Because of concerns about some aspects of the consolidation, the Navy began a test project, commonly called the Pearl Harbor pilot, to determine if integrating the management, operations, and funding of the shipyard and the intermediate maintenance facility can result in greater efficiency and lower overall ship maintenance costs. In September 1999, GAO reported that the preliminary results of the ongoing Pearl Harbor pilot were mixed and recommended that the Department of Defense (DOD) and the Navy address unresolved issues related to the financial management of the consolidation as the Navy proceeds with similar consolidations in other locations. This report updates GAO's earlier report and discusses whether (1) the Navy has provided adequate cost visibility and accountability over the consolidation, (2) DOD and the Navy have resolved other issues related to the financial structure for consolidations at Pearl Harbor and elsewhere, and (3) the consolidation has generated greater efficiency and lower costs for ship maintenance at Pearl Harbor. GAO found that the Navy still has not provided adequate …

September 11: Improvements Still Needed in Availability of Health Screening and Monitoring Services for Responders outside the New York City Area
Testimony issued by the Government Accountability Office with an abstract that begins "Six years after the attack on the World Trade Center (WTC), concerns persist about health effects experienced by WTC responders and the availability of health care services for those affected. Several federally funded programs provide screening, monitoring, or treatment services to responders. GAO has previously reported on the progress made and implementation problems faced by these WTC health programs. This testimony is based primarily on GAO's testimony, September 11: Improvements Needed in Availability of Health Screening and Monitoring Services for Responders (GAO-07-1229T, Sept. 10, 2007), which updated GAO's report, September 11: HHS Needs to Ensure the Availability of Health Screening and Monitoring for All Responders (GAO-07-892, July 23, 2007). In this testimony, GAO discusses efforts by the Centers for Disease Control and Prevention's National Institute for Occupational Safety and Health (NIOSH) to provide services for nonfederal responders residing outside the New York City (NYC) area. For the July 2007 report, GAO reviewed program documents and interviewed Department of Health and Human Services (HHS) officials, grantees, and others. GAO updated selected information in August and September 2007 and conducted work for this statement in January 2008."

Tax Systems Modernization: Results of Review of IRS' Third Expenditure Plan
A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the Internal Revenue Service's (IRS) third expenditure plan for its systems modernization project. GAO found that the plan satisfied the conditions specified in Treasury's 1998 and 1999 appropriations acts and that IRS was making progress towards satisfying Congress' direction on the Custodial Accounting Project (CAP) and Security and Technology Infrastructure Release (STIR) Project. Although IRS has made significant progress in establishing effective modernization management capability, important and challenging work remains to ensure that the systems work as intended. GAO also found that five modernization initiatives experienced schedule delays or cost increases, each of which IRS disclosed in the third plan. However, the third plan did not address whether projects' prior commitments for delivery of promised systems capabilities and benefit/business value were being met. IRS used contractor-provided "rough order-of-magnitude" estimates in preparing its third expenditure plan. However, consistent with its established practice, IRS planned to validate the third plan's estimates as part of its negotiating and definitizing contract task orders. For IRS' second expenditure plan, this process resulted in finalized contract costs that were $9 million under the "rough order-of-magnitude" estimates in the plan."

Foreign Relations: Kwajalein Atoll Is the Key U.S. Defense Interest in Two Micronesian Nations
A letter report issued by the General Accounting Office with an abstract that begins "The Compact of Free Association continues a defense arrangement that has existed between the United States and two Pacific island nations--Micronesia and the Marshall Islands--since the end of World War II. The United States has exercised only one of the four primary defense provisions contained in the Compact. That provision grants the United States the right to use part of the Kwajalein Atoll in the Marshall Islands to test nuclear missiles and space tracking operations. The United States has never been required to fulfill defense responsibilities under the other three defense provisions contained in the Compact. The Defense Department considers Kwajalein Atoll an important asset that would be costly and difficult to replicate. Ongoing negotiations over the Compact are following a course that would preserve the existing defense and security relationship between the United States and each of these nations."
