Correspondence issued by the Government Accountability Office with an abstract that begins "This letter is the formal response to a mandate in the Department of Defense and Full-Year Continuing Appropriations Act, 2011. This mandate required the Department of Homeland Security (DHS) to (1) update its Fiscal Year 2010 expenditure plan on border security fencing, infrastructure, and technology (BSFIT) for fiscal year 2011 budget authority and (2) submit the updated plan to the House and Senate Appropriations Committees. The plan is to address 10 legislative conditions in the fiscal year 2010 DHS appropriations act and be reviewed by GAO. DHS submitted an updated plan to Congress on September 8, 2011. As required by the act, we reviewed the plan."

A letter report issued by the Government Accountability Office with an abstract that begins "From fiscal years 2006 through 2010, the Department of Homeland Security (DHS) has awarded nearly $1.7 billion dollars to port areas through its Port Security Grant Program (PSGP) to protect critical maritime infrastructure and the public from terrorist attacks. The Federal Emergency Management Agency (FEMA)--a DHS component agency--is the agency responsible for distributing grant funds. GAO was asked to evaluate the extent to which DHS has (1) allocated PSGP funds in accordance with risk; (2) encountered challenges in administering the grant program and what actions, if any, DHS has taken to overcome these challenges; and (3) evaluated the effectiveness of the PSGP. To address these objectives, GAO reviewed the PSGP risk model, funding allocation methodology, grant distribution data, and program documents, such as PSGP guidance. Additionally, GAO interviewed DHS and port officials about grant processes, funding distribution, and program challenges, among other things."

A letter report issued by the Government Accountability Office with an abstract that begins "The United States has authorized billions of dollars in arms sales and exports to six Persian Gulf countries--Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates (UAE). However, regional tensions and civil conflicts have raised concerns about the security and use of arms sold or exported to these countries. The Departments of Defense (DOD) and State (State) established end-use monitoring programs to ensure that these arms are used as intended. This report assesses the extent to which DOD and State (1) safeguard U.S. military technologies sold or exported to the Gulf countries, (2) provide similar or differing levels of protection for the same military technologies, and (3) vet recipients of U.S.-funded military training and equipment for potential human rights violations. To address these objectives, GAO reviewed laws and regulations, analyzed data and documentation, and interviewed officials in Washington, D.C., and the Gulf countries."

A letter report issued by the Government Accountability Office with an abstract that begins "Declines in mail volume have brought the U.S. Postal Service (USPS) to the brink of financial insolvency. Action to ensure its financial viability is urgently needed. Visits to post offices have also declined, and in an effort to cut costs, USPS is considering closing nearly half of its 32,000 post offices by 2015. In their place, alternatives to post offices, such as the Internet, self-service kiosks, and partnerships with retailers, are increasingly important for providing access to postal services. Retail alternatives also hold potential to help improve financial performance by providing services at a lower cost than post offices. As requested, this report discusses how (1) USPS's efforts to expand access through retail alternatives support its service and financial performance goals, (2) USPS communicates with the public about retail alternatives, and (3) USPS oversees its retail partners. To conduct this work, GAO analyzed USPS documents and data and interviewed USPS officials and stakeholders. GAO also interviewed operators of postal retail partnerships."

A letter report issued by the Government Accountability Office with an abstract that begins "Since the terrorist attacks of September 11, 2001, the nation's ports and waterways have been viewed as potential targets of attack. The Department of Homeland Security (DHS) has called for using risk-informed approaches to prioritize its investments, and for developing plans and allocating resources that balance security and the flow of commerce. The U.S. Coast Guard--a DHS component and the lead federal agency responsible for maritime security--has used its Maritime Security Risk Analysis Model (MSRAM) as its primary approach for assessing and managing security risks. GAO was asked to examine (1) the extent to which the Coast Guard's risk assessment approach aligns with DHS risk assessment criteria, (2) the extent to which the Coast Guard has used MSRAM to inform maritime security risk decisions, and (3) how the Coast Guard has measured the impact of its maritime security programs on risk in U.S. ports and waterways. GAO analyzed MSRAM's risk assessment methodology and interviewed Coast Guard officials about risk assessment and MSRAM's use across the agency."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the research and development activities of the Environmental Protection Agency (EPA) and the findings of our recent report on the agency's laboratory enterprise. EPA was established in 1970 to consolidate a variety of federal research, monitoring, standard-setting, and enforcement activities into one agency for ensuring the joint protection of environmental quality and human health. Scientific research, knowledge, and technical information are fundamental to EPA's mission and inform its standard-setting, regulatory, compliance, and enforcement functions. The agency's scientific performance is particularly important as complex environmental issues emerge and evolve, and controversy continues to surround many of the agency's areas of responsibility. Unlike other primarily science-focused federal agencies, such as the National Institutes of Health or the National Science Foundation, EPA's scientific research, technical support, and analytical services underpin the policies and regulations the agency implements. Therefore, the agency operates its own laboratory enterprise. This enterprise is made up of 37 laboratories that are housed in about 170 buildings and facilities located in 30 cities across the nation. Specifically, EPA's Office of Research and Development (ORD) operates 18 laboratories with primary responsibility for research and development. Four …

A letter report issued by the Government Accountability Office with an abstract that begins "As the largest provider of financial aid in higher education, with about $134 billion in Title IV funds provided to students in fiscal year 2010, the Department of Education (Education) has a considerable interest in distance education. Distance education--that is, offering courses by the Internet, video, or other forms outside the classroom--has been a growing force in postsecondary education and there are questions about quality and adequate oversight. GAO was asked to determine (1) the characteristics of distance education today, (2) the characteristics of students participating in distance education, (3) how the quality of distance education is being assessed, and (4) how Education monitors distance education in its stewardship of federal student aid funds. GAO reviewed federal laws and regulations, analyzed Education data and documents, and interviewed Education officials and industry experts. GAO also interviewed officials from accrediting and state agencies, as well as 20 schools--which were selected based on a variety of factors to represent diverse perspectives."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses our prior work examining the Department of Homeland Security's (DHS) Science and Technology Directorate (S&T) and Research and Development (R&D) efforts. The Homeland Security Act of 2002 created DHS and, within it, established S&T with the responsibility for conducting national research, development, test and evaluation (T&E) of technology and systems for, among other things, detecting, preventing, protecting against, and responding to terrorist attacks. Since its creation in 2003, DHS, through both S&T and its components, has spent billions of dollars researching and developing technologies used to support a wide range of missions including securing the border, detecting nuclear devices, and screening airline passengers and baggage for explosives, among others. S&T has a wide-ranging mission, which includes conducting basic and applied research of technologies, and overseeing the testing and evaluation of component acquisitions and technologies to ensure that they meet DHS acquisition requirements before implementation in the field. In recent years, we have reported that DHS has experienced challenges in managing its multibillion-dollar technology development and acquisition efforts, including implementing technologies that did not meet intended requirements and were not appropriately tested and evaluated. These problems …

A letter report issued by the Government Accountability Office with an abstract that begins "What GAO Found"

Correspondence issued by the Government Accountability Office with an abstract that begins "In the National Aeronautics and Space Act of 1958, Congress granted the National Aeronautics and Space Administration (NASA) authority to enter into transactions other than contracts, leases, and cooperative agreements; this gave the agency greater flexibility in achieving its mission. NASA uses its other transaction authority through three kinds of instruments known as Space Act agreements. Specifically, NASA uses reimbursable agreements when costs associated with an undertaking are reimbursed by the agreement partner (in full or in part); the agency uses non-reimbursable agreements when each party bears the cost of participation in mutually beneficial activities. In 2006, NASA began to use a third kind of agreement--referred to as funded Space Act agreements--that have involved NASA providing significant funds to private industry partners to stimulate the development of large-scale commercial space transportation capabilities. Under a funded Space Act agreement, appropriated funds are transferred to a domestic partner, such as a private company or a university, to accomplish an agency mission. These agreements differ from Federal Acquisition Regulation (FAR) contracts in that they do not include requirements that generally apply to government contracts entered into under the authority of the …

Several research themes were developed during the course of this project. (1) Low-frequency oceanic varibility; (2) The role of eddies in the Antarctic Circumpolar Current (ACC) region; (3) Deep stratification and the overturning circulation. The key findings were as follows: (1) The stratification below the main thermocline (at about 500m) is determined in the circumpolar region and then communicated to the enclosed portions of the oceans through the overturning circulation. (2) An Atlantic pole-to-pole overturning circulation can be maintained with very small interior mixing as long as surface buoyancy values are shared between the northern North Atlantic and the ACC region.

The current status of the determinations of CKM matrix element |V{sub ub}| via exclusive and inclusive charmless semileptonic B decays is reviewed. The large datasets collected at the B-Factories, and the increased precision of theoretical calculations have allowed an improvement in the determination of |V{sub ub}|. However, there are still significant uncertainties. In the exclusive approach, the most precise measurement of the pion channel branching ratio is obtained by an untagged analysis. This very good precision can be reached by tagged analyses with more data. The problem with exclusive decays is that the strong hadron dynamics can not be calculated from first principles and the determination of the form factor has to rely on light-cone sum rules or lattice QCD calculations. The current data samples allow a comparison of different FF models with data distributions. With further developments on lattice calculations, the theoretical error should shrink to reach the experimental one. The inclusive approach still provides the most precise |V{sub ub}| determinations. With new theoretical calculations, the mild (2.5{sigma}) discrepancy with respect to the |V{sub ub}| value determined from the global UT fit has been reduced. As in the exclusive approach, theoretical uncertainties represent the limiting factor to the precision …

The Large Area Telescope (LAT) on-board the Fermi Gamma-ray Space Telescope began its on-orbit operations on June 23, 2008. Calibrations, defined in a generic sense, correspond to synchronization of trigger signals, optimization of delays for latching data, determination of detector thresholds, gains and responses, evaluation of the perimeter of the South Atlantic Anomaly (SAA), measurements of live time, of absolute time, and internal and spacecraft boresight alignments. Here we describe on-orbit calibration results obtained using known astrophysical sources, galactic cosmic rays, and charge injection into the front-end electronics of each detector. Instrument response functions will be described in a separate publication. This paper demonstrates the stability of calibrations and describes minor changes observed since launch. These results have been used to calibrate the LAT datasets to be publicly released in August 2009.

We report the discovery of gamma-ray pulsations from the nearby isolated millisecond pulsar PSR J0030+0451 with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST). This discovery makes PSR J0030+0451 the second millisecond pulsar to be detected in gamma-rays after PSR J0218+4232, observed by the EGRET instrument on the Compton Gamma Ray Observatory. The spin-down power {dot E} = 3.5 x 10{sup 33} ergs s{sup -1} is an order of magnitude lower than the empirical lower bound of previously known gamma-ray pulsars. The emission profile is characterized by two narrow peaks, respectively 0.07 {+-} 0.01 and 0.08 {+-} 0.02 wide, separated by 0.44 {+-} 0.02 in phase. The first gamma-ray peak falls 0.15 {+-} 0.01 after the main radio peak. The pulse shape is similar to that of the 'normal' gamma-ray pulsars. An exponentially cut-off power-law fit of the emission spectrum leads to an integral photon flux above 100 MeV of (6.76 {+-} 1.05 {+-} 1.35) x 10{sup -8} cm{sup -2} s{sup -1} with cut-off energy (1.7 {+-} 0.4 {+-} 0.5) GeV. Based on its parallax distance of (300 {+-} 90) pc, we obtain a gamma-ray efficiency L{sub {gamma}}/{dot E} {approx_equal} 15% for the conversion of …

Decays of B mesons to states involving {tau} leptons can be used as a tool to search for the effects of new physics, such as those involving a charged Higgs boson. The experimental status of the decays B {yields} {tau}{nu} and B {yields} D{sup (*)}{tau}{nu} is discussed, together with limits on new physics effects from current results. Leptonic and semileptonic decays of B mesons into states involving {tau} leptons remain experimentally challenging, but can prove a useful tool for constraining Standard Model parameters, and also offer to constrain the effects of any new physics that may exist including the presence of a charged Higgs boson.
