A letter report issued by the Government Accountability Office with an abstract that begins "Established in 1934 to enforce the securities laws and protect investors, the Securities and Exchange Commission (SEC) plays an important role in maintaining the integrity of the U.S. securities markets. Pursuant to the Accountability of Tax Dollars Act of 2002, SEC is required to prepare and submit to Congress and the Office of Management and Budget audited financial statements. GAO agreed, under its audit authority, to perform the audit of SEC's financial statements. GAO's audit determined whether, in all material respects, (1) SEC's fiscal year 2008 financial statements were reliable and (2) SEC's management maintained effective internal control over financial reporting and compliance with laws and regulations. GAO also tested SEC's compliance with selected laws and regulations."

A letter report issued by the Government Accountability Office with an abstract that begins "Millions of retired Americans rely on defined benefit pension plans for their financial well-being. Recent reports have noted that some plans are investing in 'alternative' investments such as hedge funds and private equity funds. This has raised concerns, given that these two types of investments have qualified for exemptions from federal regulations, and could present more risk to retirement assets than traditional investments. To better understand this trend and its implications, GAO was asked to examine (1) the extent to which plans invest in hedge funds and private equity; (2) the potential benefits and challenges of hedge fund investments; (3) the potential benefits and challenges of private equity investments; and (4) what mechanisms regulate and monitor pension plan investments in hedge funds and private equity. To answer these questions GAO interviewed relevant federal agencies, public and private pension plans, industry groups and investment professionals, and analyzed available survey data."

A letter report issued by the Government Accountability Office with an abstract that begins "Over the past several years, GAO has issued numerous reports and testimonies on internal control breakdowns in certain individual agencies' purchase card programs. In light of these findings, GAO was asked to analyze purchase card transactions governmentwide to (1) determine whether internal control weaknesses existed in the government purchase card program and (2) if so, identify examples of fraudulent, improper, and abusive activity. GAO used statistical sampling to systematically test internal controls and data mining procedures to identify fraudulent, improper, and abusive activity. GAO's work was not designed to determine the overall extent of fraudulent, improper, or abusive transactions."

A letter report issued by the Government Accountability Office with an abstract that begins "In spring 2007, the Department of Health and Human Services (HHS), the Department of Homeland Security (DHS), and state and local health officials worked together to interdict two individuals with drug-resistant infectious tuberculosis (TB) from crossing U.S. borders and direct them to treatment. Concerns arose that HHS's and DHS's responses to the incidents were delayed and ineffective. GAO was asked to examine (1) the factors that affected HHS's and DHS's responses to the incidents, (2) the extent to which HHS and DHS made changes to response procedures as a result of the incidents, and (3) HHS's and DHS's efforts to assess the effectiveness of changes made as a result of the incidents. GAO reviewed agency documents and interviewed officials about the procedures in place at the time of the incidents and changes made since."

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Emergency Management Agency (FEMA), the Department of Homeland Security (DHS) agency that administers the National Flood Insurance Program (NFIP), estimates that subsidized properties--those that receive discounted premium rates that do not fully reflect the properties' actual flood risk--experience as much as five times the flood damage as properties that do not qualify for subsidized rates. Almost one in every four residential policies has subsidized rates that are on average 35-40 percent of the full-risk rate. Unprecedented losses from the 2005 hurricane season and NFIP's periodic need to borrow from the Department of the Treasury to pay flood insurance claims has raised concerns about the impact that subsidized premium rates have on the longterm financial solvency of NFIP. GAO designated NFIP as high-risk in March 2006; as of June 2008, NFIP's debt stood at $17.4 billion. This report (1) provides information on NFIP's inventory of subsidized properties and (2) examines NFIP's current approach to subsidized properties and the advantages and disadvantages of options for reducing the costs associated with these properties. To do this work, GAO analyzed data on policies and claims and collected available …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) use of unmanned aircraft systems (UAS) continues to increase. In 2000, DOD components had fewer than 50 unmanned aircraft in their inventory. By May 2008, they had more than 6,000. However, DOD faces challenges, such as UAS acquisition and the integration of UAS into joint combat operations. GAO has made a series of recommendations to address challenges, including the need for a UAS strategic plan. To improve upon the management and use of UAS, DOD has implemented several actions, such as establishing new task forces. GAO was asked to (1) identify key DOD efforts to improve the management and operational use of UAS and (2) assess the extent to which these efforts constitute an overarching organizational framework to guide and oversee UAS efforts. GAO reviewed DOD documents such as directives and memorandums, and interviewed agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, the Department of Veterans Affairs (VA) paid about $3.5 billion in means-tested pension benefits to over 500,000 veterans and survivors. GAO was asked to review the management of VA pension program. This report assesses (1) the characteristics and trends in size of the current pensioner population, (2) the policies and procedures VA has in place to ensure that initial pension eligibility decisions are well managed, and (3) the procedures VA has in place to ensure that pensioners continue to receive the proper benefit payments on an ongoing basis. Our study included reviews of agency policies, procedures, and internal controls; site visits to 4 of VA's 57 regional offices and all three of its pension maintenance centers; and a selected file review of new claims at three locations."

A letter report issued by the Government Accountability Office with an abstract that begins "To help secure the nation's ports against a terrorist attack, federal regulations have required cargo and other maritime facilities to have security plans in place since July 2004. U.S Coast Guard (USCG) guidance calls for an annual inspection to ensure that plans are being followed. Federal law enacted in October 2006 required such facilities to be inspected two times a year--one of which is to be conducted unannounced. The USCG plans to conduct one announced inspection and the other as a less comprehensive unannounced "spot check." GAO examined the extent to which the USCG (1) has met inspection requirements and found facilities to be complying with their plans, (2) has determined the availability of trained personnel to meet current and future facility inspection requirements, and (3) has assessed the effectiveness of its facility inspection program and ensured that program compliance data collected and reported are reliable. GAO analyzed USCG compliance data, interviewed inspectors and other stakeholders in 7 of 35 USCG sectors of varying size, geographic location, and type of waterway."

A letter report issued by the Government Accountability Office with an abstract that begins "Amid ongoing operations in Iraq and Afghanistan, the Army embarked in 2004 on a plan to create a modular, brigade-based force that would be equally capable as its divisional predecessor in part because it would have advanced equipment and specialized personnel. GAO has previously reported that restructuring and rebuilding the Army will require billions of dollars for equipment and take years to complete. For this report, GAO assessed the extent to which the Army has (1) developed a plan to link funding with results and (2) evaluated its modular force designs. GAO analyzed Army equipment and personnel data, key Army reports, planning documents, performance metrics, testing plans, and funding requests. GAO also visited Army Training and Doctrine Command, including selected Army proponents and schools; Army Reserve Command; and the National Guard Bureau."

A letter report issued by the Government Accountability Office with an abstract that begins "Individual retirement accounts (IRA) allow individuals to save for retirement in a tax-preferred way. Traditional IRA contributions, subject to certain limitations, can be deducted from taxable earnings and taxes on earnings are deferred until distribution. In contrast, Roth IRA contributions are made after tax and distributions are tax-free. Faced with a myriad of rules covering IRA contributions and distributions, taxpayers may fail to comply with the rules. GAO was asked to (1) provide an overview of key rules and describe how the Internal Revenue Service (IRS) educates taxpayers about these rules, (2) describe what IRS knows about the extent of noncompliance with IRA transactions reported on taxpayer returns, and (3) describe challenges taxpayers face with key rules and some options for strengthening compliance. GAO reviewed IRS documents and compliance data. To identify challenges, GAO interviewed officials from the financial industry and advisor representatives."

A letter report issued by the Government Accountability Office with an abstract that begins "Under the Freedom of Information Act (FOIA), federal agencies must generally provide access to their information, enabling the public to learn about government operations and decisions. To help ensure proper implementation, the act requires that agencies report annually to the Attorney General on their processing of FOIA requests. For fiscal year 2006, agencies were also to report on their progress in implementing plans to improve FOIA operations, as directed by a December 2005 Executive Order. A major goal of the order was reducing backlogs of overdue FOIA requests (the statute requires an agency to respond to requests within 20 or, in some cases, 30 working days with a determination on whether it will provide records). For this study, GAO was asked, among other things, to determine trends in FOIA processing and agencies' progress in addressing backlogs of overdue FOIA requests since implementing their improvement plans. To do so, GAO analyzed 21 agencies' annual reports and additional statistics."

A letter report issued by the Government Accountability Office with an abstract that begins "By law, GAO annually assesses the Missile Defense Agency's (MDA) progress in developing and fielding a Ballistic Missile Defense System (BMDS). Funded at $8 billion to nearly $10 billion per year, it is the largest research and development program in the Department of Defense (DOD). The program has been managed in 2-year increments, known as blocks. Block 2006, the second BMDS block, was completed in December 2007. GAO assessed MDA's progress in (1) meeting Block 2006 goals for fielding assets, completing work within estimated cost, conducting tests, and demonstrating the performance of the overall system in the field, and (2) making managerial improvements to transparency, accountability, and oversight. In conducting the assessment, GAO reviewed the assets fielded; contractor cost, schedule, and performance; and tests completed during 2007. GAO also reviewed pertinent sections of the U.S. Code, acquisition policy, and the charter of a new missile defense board."

A letter report issued by the Government Accountability Office with an abstract that begins "The nation's long-term fiscal imbalances will likely make DOD's $1.6 trillion planned investment in new weapon systems unsustainable. Thus, it is critical that DOD retains the flexibility to end programs and contracts when necessary and appropriate. Although the federal government generally has the legal right to terminate contracts for convenience, defense stakeholders have sometimes expressed concerns that it will cost more to terminate a contract than to complete it. To address this perception, GAO examined (1) how expected contract termination costs and other factors affect DOD decisions on whether to end programs and contracts; (2) the circumstances under which it would cost more to terminate a contract for convenience than to complete it; and (3) the options DOD has for retaining value or reducing costs, when DOD ends programs or contracts. To do this, GAO examined DOD data on terminated contracts over $100 million; reviewed laws, regulations, and guidance; and met with key DOD officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Congress mandated that the United States Trade Representative (USTR) annually assess China's trade compliance and report its findings to Congress. In addition, USTR conducted an interagency "top-to-bottom review" of U.S. trade policies toward China. USTR's resulting February 2006 report outlined U.S objectives and action items. GAO was asked to (1) evaluate USTR's annual China trade compliance reports to Congress and the degree to which they present information necessary to fully understand China's compliance situation and (2) examine the status of the plans presented in USTR's February 2006 top-to-bottom report. GAO systematically analyzed the contents of USTR's compliance reports from 2002 to 2007 and reviewed information on the status of agencies' monitoring and enforcement activities."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) included authorizations of nearly $2.2 billion for safety incentive grant programs to assist states in their efforts to reduce traffic fatalities. Administered by the Department of Transportation's (DOT) National Highway Traffic Safety Administration (NHTSA), five of these programs provide incentive grants to states to implement legislation governing the use of safety belts and child safety seats, and promote activities to reduce alcohol-impaired driving, improve motorcycle training and awareness, and improve traffic safety information systems. To help Congress prepare for the reauthorization of the surface transportation programs in 2009, this report provides information on (1) NHTSA's status in awarding and overseeing states' use of these five grants programs, (2) activities states have conducted using the grants and issues they have faced in applying for and implementing the grants, and (3) how NHTSA plans to evaluate the results of the grant programs and implications for reauthorizing the programs. To conduct this work, GAO interviewed DOT and state officials, analyzed safety reports from 50 states, and analyzed grant data from DOT and 7 selected …

A letter report issued by the Government Accountability Office with an abstract that begins "Traffic crashes kill thousands of Americans every year--in 2005, it was the leading cause of death among young Americans. To try to improve highway safety, Congress authorized a grant program overseen by the Department of Transportation's (DOT) National Highway Traffic Safety Administration (NHTSA). In 2003, GAO recommended that NHTSA improve the consistency of its management reviews, a key aspect of NHTSA's oversight. In response to a legislative mandate, GAO assessed (1) how states have used grant funding to address safety goals, (2) NHTSA's progress in improving consistency in its management reviews, (3) the usefulness of its management review recommendations, and (4) approaches to further improve safety. In performing this work, GAO reviewed traffic safety data, analyzed state spending patterns, conducted site visits with eight states, and interviewed agency officials."

The radioactive startup of two new SRS processing facilities, the Actinide Removal Process (ARP) and the Modular Caustic-Side-Solvent-Extraction Unit (MCU) will add two new waste streams to the Defense Waste Processing Facility (DWPF). The ARP will remove actinides from the 5.6 M salt solution resulting in a sludge-like product that is roughly half monosodium titanate (MST) insoluble solids and half sludge insoluble solids. The ARP product will be added to the Sludge Receipt and Adjustment Tank (SRAT) at boiling and dewatered prior to pulling a SRAT receipt sample. The cesium rich MCU stream will be added to the SRAT at boiling after both formic and nitric acid have been added and the SRAT contents concentrated to the appropriate endpoint. A concern was raised by an external hydrogen review panel that the actinide loaded MST could act as a catalyst for hydrogen generation (Mar 15, 2007 report, Recommendation 9). Hydrogen generation, and it's potential to form a flammable mixture in the off-gas, under SRAT and Slurry Mix Evaporator (SME) processing conditions has been a concern since the discovery that noble metals catalyze the decomposition of formic acid. Radiolysis of water also generates hydrogen, but the radiolysis rate is orders of magnitude …

In this research and development project, LLNL will leverage the process for fabrication of the membranes developed by our internally funded effort (LLNL Laboratory Directed Research and Development). LLNL will then employ chemical manipulations to modify charge at the ends of the nanotubes and make the membranes more selective to either positive or negative ions through a combination of size and charge selectivity. LLNL's goal is to demonstrate ion exclusion while preserving high permeabilities and low energy use. Success of this research and development project may warrant further developments in the fabrication of membranes.

Working at Lawrence Livermore National Laboratory (LLNL) this summer has provided a very unique and special experience for me. I feel that the research opportunities given to me have allowed me to significantly benefit my research group, the laboratory, the Department of Homeland Security, and the Department of Energy. The researchers in the Single Particle Aerosol Mass Spectrometry (SPAMS) group were very welcoming and clearly wanted me to get the most out of my time in Livermore. I feel that my research partner, Veena Venkatachalam of MIT, and I have been extremely productive in meeting our research goals throughout this summer, and have learned much about working in research at a national laboratory such as Lawrence Livermore. I have learned much about the technical aspects of research while working at LLNL, however I have also gained important experience and insight into how research groups at national laboratories function. I believe that this internship has given me valuable knowledge and experience which will certainly help my transition to graduate study and a career in engineering. My work with Veena Venkatachalam in the SPAMS group this summer has focused on two major projects. Initially, we were tasked with an analysis of data …

The U.S. Department of Energy’s (DOE) commitment to assuring the health and safety of its workers includes the conduct of illness and injury surveillance activities that provide an early warning system to detect health problems among workers. The Illness and Injury Surveillance Program monitors illnesses and health conditions that result in an absence, occupational injuries and illnesses, and disabilities and deaths among current workers.

Laboratory radioactive sources were used to characterize the phoswich detector. The CaF{sub 2} scintillator has a low light-yield and slow decay time, thus produces very small signals due to low-energy gamma rays or X-rays. Therefore, detection of 30 keV X-rays (from the xenon radioisotopes) using this layer and discriminating its very small signals from electronic noise was a challenging task. Several solutions were considered and experimentally evaluated. We found that the best solution would be extending the fast triangular filter from 10 taps to 30 taps. This will extend the peaking time of this filter from 25 nsec to 75 nsec. The digital filter is implemented in FPGA on our DPP2.0 and is used to trigger the detection system. Functionality of the new filter in capturing and discriminating 30 keV X-rays was confirmed by using a {sup 133}Ba gamma-ray source. Development of the DPP GUI software has continued with the addition of two new panels to display histograms of beta/gamma and beta/x-ray coincidence events. This includes coincidence events from a single channel, as well as two-channel, coincidence event. A pileup rejection algorithm has been implemented in the FPGA code, and controls to adjust its sensitivity have been added to the …

A linear CKM relation, {bar {eta}} = tan {Phi}{sub 3/2}({bar p} - 0.24 {+-} 0.03), involving a 1{sigma} range for {Phi}{sub 3/2}, 20{sup o} < {Phi}{sub 3/2} < 115{sup o}, is obtained from B{sup 0} {yields} K*{pi} amplitudes measured recently in Dalitz plot analyses of B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} and B{sup 0}(t) {yields} K{sub S}{pi}{sup +}{pi}{sup -}. This relation is consistent within the large error on {Phi}{sub 3/2} with other CKM constraints which are unaffected by new b {yields} s{bar q}q operators. Sensitivity of the method to a new physics contribution in the {Delta}S = {Delta}I = 1 amplitude is discussed.

The purpose of this Cooperative Research and Development Agreement (CRADA) was to explore and develop advanced manufacturing techniques to fabricate sintered iron-aluminide intermetallic porous bodies used for gas filtration so as to reduce production costs while maintaining or improving performance in advanced coal gasification and combustion systems. The use of a power turbine fired with coal-derived synthesis gas requires some form of gas cleaning in order to protect turbine and downstream components from degradation by erosion, corrosion, and/or deposition. Hot-gas filtration is one form of cleaning that offers the ability to remove particles from the gases produced by gasification processes without having to substantially cool and, possibly, reheat them before their introduction into the turbine. This technology depends critically on materials durability and reliability, which have been the subject of study for a number of years.

This research program was designed to enhance our understanding of the behavior of fluids and fluid mixtures containing chain-like molecules. The original objective was to explain and predict the experimentally observed thermophysical properties, including phase equilibria and dynamics, of systems containing long flexible molecules ranging in length from alkanes to polymers. Over the years the objectives were expanded to include the treatment of molecules that were not chain-like. Molecular dynamics and Monte Carlo computer simulations were used to investigate how variations in molecular size, shape and architecture influence the types of phase equilibria, thermodynamic properties, structure and surface interactions that are observed experimentally. The molecular insights and theories resulting from this program could eventually serve as the foundation upon which to build correlations of the properties of fluids that are both directly and indirectly related to the Nation’s energy resources including: petroleum, natural gas, and polymer solutions, melts, blends, and materials.
