A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. government annually controls billions of dollars worth of U.S. arms and dual-use items exported to its allies and partners through a system of laws, regulations, and processes. Weaknesses in this system led GAO in 2007 to include export controls as part of a high-risk area and called for a reexamination, including evaluating alternative approaches. Increasing international collaboration on defense programs also makes it important to understand how other countries control exports. Proposed treaties would change the process for the export or transfer of certain U.S. arms to the United Kingdom and Australia. Based on a request to review allies' export control systems and the proposed treaties, this report (1) identifies how selected allies' systems differ from the U.S. system, and (2) assesses how the proposed treaties will change controls on arms exports. To conduct its work, GAO selected six countries--Australia, Canada, France, Germany, Japan, and the United Kingdom--based on factors such as whether they were major destinations for U.S. goods or significant arms exporters; conducted site visits in four countries; analyzed agency documentation on the foreign and U.S. systems and treaty related documents; and …

A letter report issued by the Government Accountability Office with an abstract that begins "Teen drivers ages 16 to 20 have the highest fatality rate of any age group in the United States. As a result, states have increasingly adopted laws to limit teen driving exposure, such as Graduated Driver Licensing (GDL) systems, which consist of three stages: a learner's permit allowing driving only under supervision; intermediate licensure allowing unsupervised driving with restrictions; and full licensure. The National Highway Traffic Safety Administration (NHTSA), within the Department of Transportation (DOT), supports state teen driver safety programs by researching teen driver safety issues, working to limit teens' access to alcohol, promoting seat belt use, and encouraging states to implement GDL systems. This requested report identifies (1) key GDL system requirements and the extent to which state programs include these requirements, and (2) challenges states face to improve teen driver safety and how states and NHTSA have addressed the challenges. GAO examined state GDL systems, visited six states, and interviewed federal and state traffic safety officials and other experts."

Correspondence issued by the Government Accountability Office with an abstract that begins "Terrorist attacks on mass transit and commuter rail facilities in Moscow, Madrid, London, and Mumbai, and the significant loss of life and disruption they caused, have highlighted the vulnerability of transportation facilities to terrorism and the need for greater focus on securing these facilities, including intermodal transportation terminals. Such intermodal transportation terminals--locations where multiple modes or types of passengers or cargo transportation connect an merge--are potentially high value targets for terrorists because the large number of passengers or volume of cargo can lead to significant loss of human life and economic disruption. For example, New York City's Pennsylvania ("Penn") Station, the nation's busiest rail station, functions as an intermodal hub for Amtrak, two ma commuter rail lines (New Jersey Transit and the Long Island Rail Road), as well as six city subway routes. According to Amtrak, an average of 500,000 passengers the station daily. The Department of Homeland Security (DHS) has primary responsibility for homeland security, including transportation security, under the Homeland Security Act. Within DHS, the Transportation Security Administration (TSA) has primary responsibility for securing the aviation and surface transportation sectors. The Department of Transportation (DOT) supports …

Correspondence issued by the Government Accountability Office with an abstract that begins "From September 2001 through January 2010, Congress provided about $1.023 trillion in supplemental and annual appropriations in response to Department of Defense (DOD) requests for funding to support overseas contingency operations (OCO). In March 2010, DOD reported obligations of about $825 billion attributed to OCO for the period September 2001 through January 2010. DOD uses available cost-related information, along with other financial information, to evaluate OCO trends, formulate OCO funding requests, and monitor the costs of overseas operations. In addition, Congress considers this information in its deliberations on DOD requests for additional OCO funding. Our prior reviews have found the financial information in DOD's monthly OCO reports to be of questionable reliability. For example, we identified problems in DOD's processes for recording and reporting obligations, such as not including all OCO costs and the lack of a systematic process for ensuring that data are correctly entered into those systems. Consequently, we concluded DOD's reported OCO costs should be considered approximations. Based on our prior work, we made a number of recommendations to improve the reliability of OCO reported costs, with which DOD generally concurred. Consistent with our recommendations, …

A letter report issued by the Government Accountability Office with an abstract that begins "A hallmark of efforts to implement the $862 billion American Recovery and Reinvestment Act of 2009 (Recovery Act) is to be transparent and accountable about what the money is being spent on and what is being achieved. To help achieve these goals, recipients are to report every 3 months on their award activities and expected outcomes, among other things. This information is available on Recovery.gov, the government's official Recovery Act Web site. As requested, this report covers 11 federal programs focused on broadband, energy, transportation, federal buildings, and civil works activities, representing $67 billion in Recovery Act funding. Primarily, the report (1) describes how the Office of Management and Budget (OMB) and federal agencies implemented the act to report funds' uses and (2) assesses the extent to which descriptions of awards meet GAO's transparency criteria. It also describes reported uses of funds for the 11 programs. GAO reviewed requirements for reporting in the act and OMB's guidance. Based on these requirements, GAO developed a transparency assessment and applied it to a probability sample of descriptions from 14,089 recipient reports. In addition, GAO reviewed 52 projects in …

Testimony issued by the Government Accountability Office with an abstract that begins "Higher education has become more accessible than ever before, although students from some demographic groups still face challenges in attending college. To help improve access to higher education for minority and low-income students, Titles III and V of the Higher Education Act, as amended, provide grants to strengthen and support institutions that enroll large proportions of these students. GAO was asked to testify on the Department of Education's (Education) oversight of institutions receiving Title III or V grants and progress Education has made in monitoring the financial and programmatic performance of Title III and V grantees. GAO's testimony is based primarily on its recent report, Low-Income and Minority Serving Institutions: Management Attention to Long-standing Concerns Needed to Improve Education's Oversight of Grant Programs (GAO-09-309, August 2009) and updated information provided by Education. In that report, GAO recommended that Education, among other things, (1) develop a comprehensive, risk-based approach to target monitoring and technical assistance; (2) ensure staff training needs are fully met; (3) disseminate information about implementation challenges and successful projects; and (4) develop appropriate feedback mechanisms. No new recommendations are being made in this testimony."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs (VA) provides medical care, disability compensation, and vocational rehabilitation to veterans. The Veterans Health Administration (VHA)--a component of VA--provides care to over 5 million patients in more than 1,500 facilities. VHA relies on an outpatient scheduling system that is over 25 years old. In 2000, VHA began the Scheduling Replacement Project to modernize this system as part of a larger departmentwide modernization effort called HealtheVet. However, in February 2009, VA terminated a key contract supporting the project. GAO was asked to (1) determine the status of the Scheduling Replacement Project, (2) determine the effectiveness of VA's management and oversight of the project, and (3) assess the impact of the project on VA's overall implementation of its HealtheVet initiative. To do so, GAO reviewed project documentation and interviewed VA and contractor officials."

A letter report issued by the Government Accountability Office with an abstract that begins "In the 8 years since a contract was awarded, the National Polar-orbiting Operational Environmental Satellite System (NPOESS)--a tri-agency program managed by the National Oceanic and Atmospheric Administration (NOAA), the Department of Defense (DOD), and the National Aeronautics and Space Administration (NASA)--has experienced escalating costs, schedule delays, and ineffective interagency management. The launch date for a demonstration satellite has been delayed by over 5 years and the cost estimate for the program has more than doubled--to about $15 billion. In February 2010, a Presidential task force decided to disband NPOESS and, instead, have the agencies undertake separate acquisitions. GAO was asked to (1) assess efforts to establish separate satellite programs; (2) evaluate the status and risks of the NPOESS components still under development; and (3) evaluate the implications of using the demonstration satellite's data operationally. To do so, GAO analyzed program management and cost data, attended program reviews, and interviewed agency officials."

Testimony issued by the Government Accountability Office with an abstract that begins "Earlier this month, United Air Lines (United) and Continental Airlines (Continental) announced plans to merge the two airlines and signed a merger agreement. This follows the acquisition of Northwest Airlines by Delta Air Lines (Delta) in 2008, which propelled Delta to become the largest airline in the United States. This latest merger, if not challenged by the Department of Justice (DOJ), would surpass Delta's merger in scope to create the largest passenger airline in terms of capacity in the United States. The passenger airline industry has struggled financially over the last decade, and these two airlines believe a merger will strengthen them. However, as with any proposed merger of this magnitude, this one will be carefully examined by DOJ to determine if its potential benefits for consumers outweigh the potential negative effects. At the Committee's request, GAO is providing a statement for the record that describes (1) an overview of the factors that are driving mergers in the industry, (2) the role of federal authorities in reviewing merger proposals, and (3) key issues associated with the proposed merger of United and Continental. To address these objectives, GAO drew …

Testimony issued by the Government Accountability Office with an abstract that begins "Multiemployer defined benefit pension plans, which are created by collective bargaining agreements covering more than one employer and generally operated under the joint trusteeship of labor and management, provide pension coverage to over 10.4 million participants in the 1,500 multiemployer plans insured by the Pension Benefit Guaranty Corporation (PBGC). Changes to the structure of the multiemployer plan framework and to PBGC's role as insurer have sought to improve plan funding. Reports of declines in plan funding have prompted questions about the financial health of these plans. The committee asked GAO to provide information on (1) the unique characteristics of multiemployer plans and (2) the challenges that multiemployer plans face and how they may affect PBGC. GAO provided a draft of this testimony to PBGC for review and comment. PBGC provided technical comments, which were incorporated, as appropriate. To address these objectives, GAO relied primarily on its previously published reports on multiemployer plans (GAO-04-423 and GAO-04-542T), and data publicly available from PBGC. GAO is not making new recommendations in this testimony."

Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has sought improved efficiencies and cost reductions in its delivery of services that could be provided by the private sector, using both competitions with private companies and processes to create high performing organizations (HPO). The Office of Management and Budget's (OMB) Circular A-76 establishes federal policy for the competition of commercial activities. According to the circular, the longstanding policy of the federal government has been to rely on the private sector for needed commercial services. To ensure that the American people receive maximum value for their tax dollars, it is the federal government's policy that commercial activities should be subject to the forces of competition. As the largest federal agency, DOD has conducted more A-76 competitions than any other federal agency. However, the A-76 process has drawn criticism from both the public and private sectors. These criticisms largely center on the costs and length of time required to conduct competitions and the manner in which long-term savings are calculated. In light of these concerns, a panel of public and private sector experts convened in 2001 to identify ways in which the federal government …

A letter report issued by the Government Accountability Office with an abstract that begins "Cloud computing, an emerging form of computing where users have access to scalable, on-demand capabilities that are provided through Internet-based technologies, has the potential to provide information technology services more quickly and at a lower cost, but also to introduce information security risks. Accordingly, GAO was asked to (1) identify the models of cloud computing, (2) identify the information security implications of using cloud computing services in the federal government, and (3) assess federal guidance and efforts to address information security when using cloud computing. To do so, GAO reviewed relevant publications, white papers, and other documentation from federal agencies and industry groups; conducted interviews with representatives from these organizations; and surveyed 24 major federal agencies."

We obtained 960,200 22-by-22-pixel windowed images of a pinhole spot using the Teledyne H2RG CMOS detector with un-cooled SIDECAR readout. We performed an analysis to determine the precision we might expect in the position error signals to a telescope's guider system. We find that, under non-optimized operating conditions, the error in the computed centroid is strongly dependent on the total counts in the point image only below a certain threshold, approximately 50,000 photo-electrons. The LSST guider camera specification currently requires a 0.04 arcsecond error at 10 Hertz. Given the performance measured here, this specification can be delivered with a single star at 14th to 18th magnitude, depending on the passband.

The spectrometer solenoid is supposed to be the first magnets installed in MICE [1]-[4]. This report described what happened during the test of the MICE spectrometer solenoid 2B. First, the report describes the temperatures in the magnet, the cooler top plate and the shield during the run where the magnet quenched at 258 A. During this quench, a lead between the bottom of the HTS leads and the diode bank burned out causing the magnet to quench. Second, three methods for measuring the net heat flow into the cold mass are described. Third, there is a discussion of possible resistive heating in the HTS leads between liquid helium temperature and the copper plate, which is at about 50 K. Fourth, there is a discussion of the measured first stage heat loads in the magnet, when there is no current in the magnet. The first stage heat load calculations are based on knowing the first stage temperatures of the three two-stage pulse tube coolers and the single stage GM cooler. Fifth, the estimated heat load to the first stage when the magnet has current in it is discussed. Sixth, there is a comparison of the stage 1 heat loads in magnet …

Up to now, the term "transport-optimized" stellarators has meant optimized to minimize neoclassical transport, while the task of also mitigating turbulent transport, usually the dominant transport channel in such designs, has not been addressed, due to the complexity of plasma turbulence in stellarators. Here, we demonstrate that stellarators can also be designed to mitigate their turbulent transport, by making use of two powerful numerical tools not available until recently, namely gyrokinetic codes valid for 3D nonlinear simulations, and stellarator optimization codes. A first proof-of-principle configuration is obtained, reducing the level of ion temperature gradient turbulent transport from the NCSX baseline design by a factor of about 2.5.

The Antarctic Ross Iceshelf Antenna Neutrino Array (ARIANNA) is a proposed detector for ultra-high energy astrophysical neutrinos. It will detect coherent radio Cherenkov emission from the particle showers produced by neutrinos with energies above about 1017 eV. ARIANNA will be built on the Ross Ice Shelf just off the coast of Antarctica, where it will eventually cover about 900 km2 in surface area. There, the ice-water interface below the shelf reflects radio waves, giving ARIANNA sensitivity to downward going neutrinos and improving its sensitivity to horizontally incident neutrinos. ARIANNA detector stations will each contain 4-8 antennas which search for brief pulses of 50 MHz to 1 GHz radio emission from neutrino interactions. We describe a prototype station for ARIANNA which was deployed in Moore's Bay on the Ross Ice Shelf in December 2009, discuss the design and deployment, and present some initial figures on performance. The ice shelf thickness was measured to be 572 +- 6 m at the deployment site.
