A letter report issued by the Government Accountability Office with an abstract that begins "Fiscal year 2006 was the first year that the Department of Defense (DOD) reported improper payment information for its travel program under the Improper Payments Information Act of 2002 (IPIA). For fiscal year 2006, DOD reported obligations of approximately $8.5 billion for travel. Congress mandated that GAO assess the reasons why DOD is not fully in compliance with IPIA related to travel expenditures. In May 2007, GAO issued an initial report in response to this mandate. To further respond, GAO assessed (1) the completeness and accuracy of DOD's fiscal year 2006 IPIA travel disclosure in its performance and accountability report (PAR), and (2) DOD's planned efforts to improve and refine its processes for estimating and reporting on travel improper payments. To complete this work, GAO reviewed DOD's IPIA reporting, IPIA, Office of Management and Budget's (OMB) IPIA implementing guidance, and met with cognizant DOD officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In enacting the Democratic Republic of the Congo (DRC) Relief, Security, and Democracy Promotion Act of 2006 (the Act), Congress established 15 U.S. policy objectives to address the DRC's humanitarian, development, economic and natural resource, governance, and security issues and mandated that GAO review actions taken by U.S. agencies to achieve these objectives. In this report, GAO identifies (1) U.S. programs and activities that support the Act's objectives, (2) major challenges hindering the accomplishment of the objectives, and (3) U.S. efforts to assess progress toward the objectives. GAO obtained and analyzed agencies' program documents and met with officials of agencies and nongovernmental organizations (NGO) active in the DRC."

A letter report issued by the Government Accountability Office with an abstract that begins "The United States has advocated reforms of United Nations (UN) management for many years. In October 2006, GAO reported that UN management reforms were progressing slowly and that many were still awaiting review by the General Assembly. For this review, GAO was asked to (1) determine the progress of UN management reform initiatives in five key areas--ethics, oversight, procurement, management operations of the Secretariat, and review of programs and activities (known as mandates)--and (2) identify factors that have slowed the pace of reform efforts. To address these objectives, GAO reviewed documents relating to UN management reform and interviewed U.S. and UN officials."

A letter report issued by the Government Accountability Office with an abstract that begins "After widespread unlawful trading practices surfaced in the mutual fund industry in late 2003, the Securities and Exchange Commission (SEC), through its Office of Compliance Inspections and Examinations (OCIE), took steps intended to revise its examination process to better identify and focus its resources on those activities representing the highest risk to investors. More recently, some registrants raised concerns about the lack of communication from SEC examiners about the status of and results of examinations. This report (1) describes OCIE's revisions after 2003 to the examination approach for investment companies and investment advisers; (2) discusses OCIE's compliance with its examination exit procedures; and (3) describes reforms OCIE implemented since January 2006 to enhance, among other things, communication with registrants. To address these objectives, GAO analyzed OCIE examination data; planning documents and guidance; interviewed OCIE officials; and gathered views of registrants."

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Retirement Thrift Investment Board (FRTIB) is charged with managing the Thrift Savings Plan (TSP)--a key component of retirement savings for many federal employees--in the interest of its participants and beneficiaries. As part of a broader request on oversight of FRTIB, GAO reviewed (1) the administrative expenses of FRTIB and key components of these expenses, (2) whether the administrative expenses of FRTIB are the result of practices consistent with federal regulations and similar functions at other agencies, and (3) FRTIB's current method of benchmarking administrative expenses. GAO reviewed FRTIB's budgets, audited financial statements, a benchmarking study, and written responses to questions that GAO submitted. GAO also reviewed the regulations that guide FRTIB's spending."

A letter report issued by the Government Accountability Office with an abstract that begins "An influenza pandemic is a real and significant potential threat facing the United States and the world. Pandemics occur when a novel virus emerges that can easily be transmitted among humans who have little immunity. In 2005, the Homeland Security Council (HSC) issued a National Strategy for Pandemic Influenza and, in 2006, an Implementation Plan. Congress and others are concerned about the federal government's preparedness to lead a response to an influenza pandemic. This report assesses how clearly federal leadership roles and responsibilities are defined and the extent to which the Strategy and Plan address six characteristics of an effective national strategy. To do this, GAO analyzed key emergency and pandemic-specific plans, interviewed agency officials, and compared the Strategy and Plan with the six characteristics GAO identified."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has established a program--the U.S. Visitor and Immigrant Status Indicator Technology (US-VISIT)--to collect, maintain, and share information, including biometric identifiers, on selected foreign nationals who travel to the United States. By congressional mandate, DHS is to develop and submit for approval an expenditure plan for US-VISIT that satisfies certain conditions, including being reviewed by GAO. GAO was required to determine if the plan satisfied these conditions, follow up on recommendations related to the expenditure plan, and provide any other observations. To address the mandate, GAO assessed plans against federal guidelines and industry standards and interviewed the appropriate DHS officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Louisiana, home to 40 percent of all coastal wetlands in the lower 48 states, is projected to lose almost 17 square miles of coastline each year for the next 50 years to storms, sea level rise, and land subsidence. Coastal wetlands are an important wildlife and commercial resource, and provide a natural buffer against the storm surge that accompanies storms and hurricanes. The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) established a program in 1990 that undertakes projects to stem coastal wetland losses. Recently, the Congress passed other measures that will make billions in new funding available for coastal Louisiana over the next 20 years. GAO has prepared this report under the Comptroller General's authority as part of a continued effort to assist the Congress. GAO reviewed the CWPPRA program to identify the (1) types of projects that have been designed and constructed to restore and protect coastal wetlands, as well as their estimated costs and benefits, and (2) lessons learned from past and ongoing restoration efforts that can help guide future efforts. GAO's review included interviews with each program agency. Although GAO is not …

A letter report issued by the Government Accountability Office with an abstract that begins "American Indians and Alaska Natives have the third highest rate of HIV/AIDS diagnosis in the United States. They are also more likely than individuals with HIV/AIDS from other racial and ethnic groups to receive treatment at later stages of the disease and have shorter life spans. The Indian Health Service (IHS), located within the Department of Health and Human Services (HHS), provides health care services, including HIV/AIDS treatment, to eligible American Indians and Alaska Natives. IHS patients with HIV/AIDS may also receive care through other sources depending on their access to private health insurance or their eligibility for other federal health care programs, such as Medicare and Medicaid. GAO examined the extent to which IHS provided (1) HIV/AIDS prevention services and (2) HIV/AIDS treatment services. GAO also examined (3) what other HIV/AIDS-related initiatives IHS has undertaken. GAO reviewed documents and interviewed officials from IHS headquarters, area offices, and IHS-funded facilities, as well as advocacy groups. We also conducted site visits in two IHS areas."

A letter report issued by the Government Accountability Office with an abstract that begins "Approximately 28 percent of all Medicare spending in 1999 was used to provide care for beneficiaries in the last year of their lives. The Medicare hospice benefit is specifically designed for end-of-life care but is an elected benefit for individuals who have a terminal diagnosis with a prognosis of 6 months or less if the disease runs its normal course. GAO was asked to identify examples of programs that provide key components of end-of-life care. Specifically, GAO (1) identified key components of end-of-life care, (2) identified and described how certain programs incorporate key components of end-of-life care, and (3) described the challenges program providers have identified to delivering the key components of end-of-life care. To identify the key components of end-of-life care, GAO relied on studies by the Institute of Medicine (IOM) and the Agency for Healthcare Research and Quality (AHRQ). To identify and describe programs that implement these key components and describe the challenges providers of these programs face, GAO conducted site visits to four states, Arizona, Florida, Oregon, and Wisconsin, that, in addition to other criteria, demonstrated a high use of end-of-life services. We …

A letter report issued by the Government Accountability Office with an abstract that begins "Increasing retirements and declining fertility rates, among other factors, could affect the labor force growth in many developed countries. To maintain the size and productivity of the labor force, many governments and employers have introduced strategies to keep workers, such as women and low-skilled workers, in the workforce throughout their working lives. Because other countries have also undertaken efforts to address issues similar to those occurring in the U.S., GAO was asked to (1) describe the policies and practices implemented in other developed countries that may help women and low-wage/low-skilled workers enter and remain in the labor force; (2) examine the targeted groups' employment following the implementation of the policies and practices; and (3) identify the factors that affect employees' use of workplace benefits and the resulting implications. We conducted an extensive review of workplace flexibility and training strategies in a range of developed countries, and we conducted site visits to selected countries. Our reviews were limited to materials that were available in English. While we identified relevant national policies in the U.S., we did not determine whether other countries' strategies could be implemented here. Labor …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) is required by law to conduct a comprehensive examination of the national defense strategy, force structure, modernization plans, infrastructure, and budget every 4 years including an assessment of the force structure best suited to implement the defense strategy at low-to-moderate level of risk. The 2006 Quadrennial Defense Review (QDR), completed in February 2006, represents the first comprehensive review that DOD had undertaken since the military forces have been engaged in operations in Iraq and Afghanistan. GAO was asked to assess (1) the strengths and weaknesses of DOD's approach and methodology for the 2006 QDR and (2) what changes, if any, in the QDR legislation could improve the usefulness of the report, including any changes that would better reflect 21st century security conditions. To conduct its review, GAO analyzed DOD's methodology, QDR study guidance, and results from key analyses and also obtained views of defense analysts within and outside of DOD."

A letter report issued by the Government Accountability Office with an abstract that begins "The Small Business Administration (SBA) is the federal government's primary provider of disaster loans to businesses, homeowners, and renters. In a previous report (GAO- 06-860), GAO found that SBA's limited information systems planning contributed to delays in processing disaster loans for the victims of the 2005 Gulf Coast Hurricanes (Katrina, Rita, and Wilma). To provide further insight into how SBA's disaster preparedness could be enhanced, this second report, initiated under the Comptroller General's authority, assesses other logistical issues (e.g., staffing and space acquisition) that may have affected the efficiency of the agency's response to the hurricanes. Specifically, this report (1) assesses SBA's logistical planning efforts prior to the Gulf Coast hurricanes and current planning efforts and (2) discusses SBA's outreach services to hurricane victims. GAO reviewed disaster planning reports, interviewed SBA officials, and visited the Gulf Coast region."

A letter report issued by the Government Accountability Office with an abstract that begins "In 1995, GAO first designated the Department of Defense's (DOD) business systems modernization program as "high risk," and GAO continues to do so today. To assist in addressing this high-risk area, the Fiscal Year 2005 National Defense Authorization Act contains provisions that are consistent with prior GAO recommendations. Further, the act requires the department to submit annual reports to its congressional committees on its compliance with these provisions and it directs GAO to review each report. In response, GAO assessed DOD's actions to address (1) requirements in the act and (2) GAO's recommendations that it reported as open in its prior annual report under the act. In doing so, GAO reviewed documentation and interviewed officials relative to the act and related guidance."

A letter report issued by the Government Accountability Office with an abstract that begins "Changes to the U.S. economy have led to longer-term unemployment. Many unemployed workers receive Unemployment Insurance (UI), which provided about $30 billion in benefits in 2006. In 1993, Congress established requirements--now known as the Worker Profiling and Reemployment Services (WPRS) initiative--for state UI agencies to identify claimants who are most likely to exhaust their benefits, and then refer such claimants to reemployment services. To assess the implementation and effect of the initiative, GAO examined (1) how states identify claimants who are most likely to exhaust benefits, (2) to what extent states provide reemployment services as recommended by the Department of Labor (Labor), and (3) what is known about the effectiveness of the initiative in accelerating reemployment. To answer these questions, we used a combination of national data; review of seven states, including visits to local service providers in four states; and existing studies and interviews with Labor and subject matter experts."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Commerce's (Commerce) U.S. Census Bureau (Bureau) seeks updated information on the addresses and maps of housing units and group quarters from state, local, and tribal governments through the Local Update of Census Addresses (LUCA) Program. Prepared under the Comptroller General's authority, this report assesses (1) the status of the LUCA Program, (2) the Bureau's response to prior recommendations by GAO and others and new challenges related to the program, and (3) the Bureau's plans for conducting the program in areas affected by hurricanes Katrina and Rita. GAO reviewed LUCA program documents, met with and surveyed participants in the LUCA Dress Rehearsal, and interviewed Bureau officials and local officials in the Gulf Coast region."

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2006, outlays for Medicaid were about $324 billion; about $185 billion was paid by the federal government. Because GAO previously identified abusive and criminal activity associated with government contractors owing billions of dollars in federal taxes, the subcommittee requested GAO expand our work to Medicaid providers. GAO was asked to (1) determine if Medicaid providers have unpaid federal taxes, and if so, the magnitude of such debts; (2) identify examples of Medicaid providers that have engaged in abusive or criminal activities; and (3) determine whether the Centers for Medicare & Medicaid Services (CMS) and the states prevent health care providers with tax problems from enrolling in Medicaid or participating in the continuous levy program to pay federal tax debts. To perform this work, GAO analyzed tax data from the Internal Revenue Service (IRS) and Medicaid data from seven selected states based on magnitude of Medicaid payments and geography. GAO also performed additional investigative activities."

A letter report issued by the Government Accountability Office with an abstract that begins "The Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) protects the rights of military personnel, their dependents, and overseas citizens to vote by absentee ballot. The Department of Defense (DOD) and others have reported that absentee voting, which relies primarily on mail, can be slow and may, in certain circumstances, serve to disenfranchise these voters. In 2004, Congress required DOD to develop an Internet-based absentee voting demonstration project and required the Election Assistance Commission--which reviews election procedures--to develop guidelines for DOD's project. In 2006, Congress required DOD to report, by May 15, 2007, on plans for expanding its use of electronic voting technologies and required GAO to assess efforts by (1) DOD to facilitate electronic absentee voting and (2) the Commission to develop Internet voting guidelines and DOD to develop an Internet-based demonstration project. GAO also assessed DOD's efforts to develop plans to expand its use of electronic voting technologies. GAO interviewed officials and reviewed and analyzed documents related to these efforts."

A letter report issued by the Government Accountability Office with an abstract that begins "The Army's modular force restructuring is a multiyear $52.5 billion initiative to redesign operational Army units. The Army also plans to spend $70 billion through fiscal year 2013 to expand the force by 74,200 military personnel. Congress mandated that GAO report annually through fiscal year 2012 on the Army's modular force. For this report, GAO assessed to what extent the Army has (1) implemented and established management controls for its modular force and force expansion initiatives, and (2) assessed its modular unit designs. GAO assessed Army plans and funding requests; visited brigades that were reorganizing; and examined key Army planning documents, performance metrics, and testing plans. Both brigade combat teams and support brigades were visited, including units from the active component Army, Army National Guard, and Army Reserve."

Due to their excellent corrosion resistance, iron aluminum alloys are currently being considered for use as weld claddings in fossil fuel fired power plants. The susceptibility to hydrogen cracking of these alloys at higher aluminum concentrations has highlighted the need for research into the effect of chromium additions on the corrosion resistance of lower aluminum alloys. In the present work, three iron aluminum alloys were exposed to simulated coal combustion environments at 500 C and 700 C for both short (100 hours) and long (5,000 hours) isothermal durations. Scanning electron microscopy was used to analyze the corrosion products. All alloys exhibited excellent corrosion resistance in the short term tests. For longer exposures, increasing the aluminum concentration was beneficial to the corrosion resistance. The addition of chromium to the binary iron aluminum alloy prevented the formation iron sulfide and resulted in lower corrosion kinetics. A classification of the corrosion products that developed on these alloys is presented. Scanning transmission electron microscopy (STEM) of the as-corroded coupons revealed that chromium was able to form chromium sulfides only on the higher aluminum alloy, thereby preventing the formation of deleterious iron sulfides. When the aluminum concentration was too low to permit selective oxidation of …

This report summarizes 4 years of research achievements in this Office of Science (BER), U.S. Department of Energy (DOE) project. The research described was conducted by scientists and supporting staff at Lovelace Respiratory Research Institute (LRRI)/Lovelace Biomedical and Environmental Research Institute (LBERI) and the Southern Urals Biophysics Institute (SUBI). All project objectives and goals were achieved. A major focus was on obtaining improved cancer risk estimates for exposure via inhalation to plutonium (Pu) isotopes in the workplace (DOE radiation workers) and environment (public exposures to Pu-contaminated soil). A major finding was that low doses and dose rates of gamma rays can significantly suppress cancer induction by alpha radiation from inhaled Pu isotopes. The suppression relates to stimulation of the body's natural defenses, including immunity against cancer cells and selective apoptosis which removes precancerous and other aberrant cells.
