A letter report issued by the Government Accountability Office with an abstract that begins "In an effort to reduce the risk of wildland fires, many federal land managers--including the Forest Service and the Bureau of Land Management (BLM)--are placing greater emphasis on thinning forests and rangelands to help reduce the buildup of potentially hazardous fuels. These thinning efforts generate considerable quantities of woody material, including many smaller trees, limbs, and brush--referred to as woody biomass--that currently have little or no commercial value. GAO was asked to determine (1) which federal agencies are involved in efforts to promote the use of woody biomass, and actions they are undertaking; (2) how these agencies are coordinating their activities; and (3) what agencies see as obstacles to increasing the use of woody biomass, and the extent to which they are addressing these obstacles."

A letter report issued by the Government Accountability Office with an abstract that begins "Based on limited previous GAO work that identified examples of purchases of new items at the same time identical items in excellent or good condition were excessed, GAO was asked to assess the overall economy and efficiency of the Department of Defense (DOD) program for excess property reutilization (reuse). Specifically, GAO was asked to determine (1) whether and to what extent the program included waste and inefficiency and (2) root causes of any waste and inefficiency. GAO was also asked to provide detailed examples of waste and inefficiency and the related causes. GAO's methodology included an assessment of controls, analysis of DOD excess inventory data, statistical sampling at selected sites, and detailed case studies of many items."

A letter report issued by the General Accounting Office with an abstract that begins "The proliferation of man-portable air defense systems (MANPADS) has been of growing concern to the United States and other governments. The United States is pursuing a wide variety of activities internationally and domestically to address this threat. GAO was asked to assess efforts by (1) the State Department to control global proliferation of MANPADS, (2) the Department of Defense (DOD) to monitor end-use of U.S.-exported Stingers, and (3) the Department of Homeland Security (DHS) to develop technical countermeasures to minimize the threat of a MANPADS attack."

A letter report issued by the Government Accountability Office with an abstract that begins "Federal policy requires that small businesses receive the maximum practicable subcontracting opportunity for providing goods and services to large businesses that contract directly with federal agencies. The Department of Energy (DOE) annually directs almost $20 billion to the 34 "facility management contractors" of which $3.3 billion was redirected to small business subcontractors in fiscal year 2004. DOE negotiates annual small business subcontracting goals with individual contractors and monitors their achievements. GAO was asked to (1) determine the usefulness of the data that DOE uses to monitor subcontracting performance and (2) discuss the actions that DOE has taken to address any problems with the contractors' subcontracting efforts."

A letter report issued by the General Accounting Office with an abstract that begins "The Global War on Terrorism--principally involving operations in Afghanistan and Iraq--was funded in fiscal year 2003 by Congress's appropriation of almost $69 billion. To assist Congress in its oversight of spending, GAO is undertaking a series of reviews relating to contingency operations in support of the Global War on Terrorism. In September 2003, GAO issued a report that discussed fiscal year 2003 obligations and funding for the war through June 2003. This report continues the review of fiscal year 2003 by analyzing obligations reported in support of the Global War on Terrorism and reviews whether the amount of funding received by the military services was adequate to cover DOD's obligations for the war from October 1, 2002, through September 30, 2003. GAO will also review the war's reported obligations and funding for fiscal year 2004."

A letter report issued by the Government Accountability Office with an abstract that begins "Federal funding to states supported more than 200,000 youth in residential facilities in 2004, many seeking help to address behavioral or emotional challenges. However, federal investigations have identified maltreatment and civil rights abuses in some facilities. GAO was asked to provide national information about (1) the nature of incidents that adversely affect youth well-being in residential facilities, (2) how state licensing and monitoring requirements address youth well-being in these facilities, and (3) what factors affect federal agencies' ability to hold states accountable for youth well-being in residential facilities. GAO conducted national Web-based surveys of state child welfare, health and mental health, and juvenile justice agencies and achieved an 85 percent response rate for each of the three surveys. We also visited four states, interviewed program officials, and reviewed laws and documentation."

A letter report issued by the Government Accountability Office with an abstract that begins "To enhance aviation security, the Department of Homeland Security's (DHS) Transportation Security Administration (TSA) developed a program--known as Secure Flight--to assume from air carriers the function of matching passenger information against terrorist watch-list records. In accordance with a mandate in the Department of Homeland Security Appropriations Act, 2008, GAO's objective was to assess the extent to which TSA met the requirements of 10 statutory conditions related to the development of the Secure Flight program. GAO is required to review the program until all 10 conditions are met. In September 2008, DHS certified that it had satisfied all 10 conditions. To address this objective, GAO (1) identified key activities related to each of the 10 conditions; (2) identified federal guidance and best practices that are relevant to successfully meeting each condition; (3) analyzed whether TSA had demonstrated, through program documentation and oral explanation, that the guidance was followed and best practices were met; and (4) assessed the risks associated with not fully following applicable guidance and meeting best practices."

A letter report issued by the Government Accountability Office with an abstract that begins "The Joint Committee on Taxation identified improved taxpayer compliance with the real-estate tax deduction as a way to reduce the federal tax gap--the difference between taxes owed and taxes voluntarily and timely paid. Regarding the deduction, GAO was asked to examine (1) factors that contribute to taxpayers including nondeductible charges, (2) the extent that taxpayers may be claiming such charges, (3) the extent that Internal Revenue Service (IRS) examinations focus on the inclusion of such charges, and (4) possible options for improving taxpayer compliance. GAO surveyed a generalizable sample of local governments, studied taxpayer compliance in two jurisdictions that met selection criteria, reviewed IRS documents, and interviewed government officials and others. Addressing the complexity of current tax law on real-estate tax deductions was outside the scope of this review."

A letter report issued by the General Accounting Office with an abstract that begins "Business-owned life insurance is permanent insurance held by employers on the lives of their employees, and the employer is the beneficiary of these policies. Its attractive features, common to all permanent life insurance, generally include both tax-deferred accumulation of earnings on the policies' cash value and tax-free receipt of the death benefit. Legislators have expressed concerns about the ability of employers to receive tax-favored treatment from insuring their employees' lives. GAO was asked to discuss (1) the prevalence and use of business-owned life insurance, (2) federal and state regulation and oversight of these policies, and (3) the potential usefulness of and costs associated with obtaining more comprehensive data on business-owned life insurance."

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the results of security tests we performed in which agents of the Office of Special Investigations (OSI), acting in an undercover capacity, entered the United States from various countries in the Western Hemisphere using counterfeit documentation and fictitious identities. This work was initially undertaken at the request of the Senate Finance Committee and was continued at the request of the Subcommittee on Immigration, Border Security, and Claims, House Committee on the Judiciary. The purpose of our tests was to determine whether U.S. government officials conducting inspections at ports of entry would detect the counterfeit identification documents."

Testimony issued by the General Accounting Office with an abstract that begins "In 2001, the Department of Health and Human Services' (HHS) Administration for Children and Families (ACF) implemented the Child and Family Services Reviews (CFSR) to increase states' accountability. The CFSR uses states' data profiles and statewide assessments, as well as interviews and an on-site case review, to measure state performance on 14 outcomes and systemic factors, including child well-being and the provision of caseworker training. The CFSR also requires progress on a program improvement plan (PIP); otherwise ACF may apply financial penalties. This testimony is based on our April 2004 report and addresses (1) ACF's and the states' experiences preparing for and conducting the statewide assessments and on-site reviews; (2) ACF's and the states' experiences developing, funding, and implementing items in PIPs; and (3) any additional efforts that ACF has taken beyond the CFSR to improve state performance. For the April 2004 report, we surveyed all 50 states, the District of Columbia, and Puerto Rico regarding their experiences throughout the CFSR process, visited 5 states to obtain first-hand information, and conducted a content analysis of all 31 available PIPs as of January 1, 2004. We also interviewed HHS …

Testimony issued by the Government Accountability Office with an abstract that begins "Since its inception, the Transportation Security Administration (TSA) has focused much of its efforts on aviation security, and has developed and implemented a variety of programs and procedures to secure commercial aviation. More recently, TSA has taken actions to secure the nation's surface transportation modes. TSA funding for aviation security has totaled about $26 billion since fiscal year 2004, and for surface transportation security activities, about $175 million since fiscal year 2005. This testimony focuses on TSA's efforts to secure the commercial aviation system-- through passenger screening, air cargo, and watch-list matching programs--and the nation's surface transportation modes. It also addresses challenges remaining in these areas. GAO's comments are based on GAO products issued from February 2004 through April 2008 including selected updates obtained in February through April 2008."

Testimony issued by the General Accounting Office with an abstract that begins "The U.S. Postal Service continues to face financial and transformation challenges. Since GAO placed the Service's long-term outlook and transformation efforts on its high-risk list, the Service's financial situation has continued to decline, and its operational challenges have increased. The Service took a good first step when it issued its Transformation Plan. The plan provides information about the Service's challenges, identifies many actions the Service plans to take under its existing authority, and outlines steps that would require congressional action. The plan does not, however, adequately address some key issues or include an action plan with key milestones. The catastrophic events of September 11 and subsequent anthrax scares, coupled with the recent economic slowdown, have decreased mail volumes and revenues. However, the Service's financial difficulties are not just a cyclical phenomenon that will fade as the economy recovers. The Service's basic business model, which assumes that rising mail volume will cover rising costs and mitigate rate increases, is questionable as mail volumes stagnate or deteriorate in an increasingly competitive environment. The Service's Transformation Plan recognizes that postal costs are rising faster than revenues and identifies many actions that …

Testimony issued by the General Accounting Office with an abstract that begins "The Subcommittee on Government Efficiency and Financial Management, House Committee on Government Reform asked GAO to testify on the Improper Payments Information Act (PL-107-300) and related draft guidance issued by the Office of Management and Budget (OMB), and on GAO recommendations to agencies on actions they can take to prevent or reduce improper payments."

Testimony issued by the General Accounting Office with an abstract that begins "Since 1998, the 34 democratic nations of the Western Hemisphere have been negotiating a Free Trade Area of the Americas agreement to eliminate tariffs and create common trade and investment rules for these nations. The United States will co-chair, with Brazil, the final phase of the negotiations, due to conclude in January 2005. GAO was asked to (1) review challenges that the United States faces as co-chair of the final negotiating phase and (2) discuss risks that the United States may encounter, as host, in Miami, of the November 2003 ministerial meeting."

A letter report issued by the Government Accountability Office with an abstract that begins "Cost growth is a prevalent problem in Navy shipbuilding programs, particularly for the first ships in new classes. In response to a mandate in the conference report accompanying the Defense Appropriations Act for Fiscal Year 2008, GAO undertook this review to (1) identify key practices employed by leading commercial ship buyers and shipbuilders that ensure satisfactory cost, schedule, and ship performance; (2) determine the extent to which Navy shipbuilding programs employ these practices; and (3) evaluate how commercial and Navy business environments incentivize the use of best practices. To address these objectives, GAO visited leading commercial ship buyers and shipbuilders, reviewed its prior Navy work, and convened a panel of shipbuilding experts."

The report includes a table that lists and describes actions taken by the Senate, the Senate Judiciary Committee, and the President on all Supreme Court nominations, from 1789 to the present.

The 2002 farm bill required retailers to provide country-of-origin labeling (COOL) for fresh produce, red meats, peanuts, and seafood by September 30, 2004. Congress twice postponed implementation for all bu seafood; COOL now must be implemented by September 30, 2008. This report describes the current status of the COOL issue, as well as the ongoing discussion of additional COOL requirements for other foods and food ingredients as part of the proposed Federal Food, Drug, and Cosmetic Act overhaul.

As part of the Global Nuclear Energy Partnership (GNEP), a fast reactor simulation program was launched in April 2007 to develop a suite of modern simulation tools specifically for the analysis and design of sodium cooled fast reactors. The general goal of the new suite of codes is to reduce the uncertainties and biases in the various areas of reactor design activities by enhanced prediction capabilities. Under this fast reactor simulation program, a high-fidelity deterministic neutron transport code named UNIC is being developed. The final objective is to produce an integrated, advanced neutronics code that allows the high fidelity description of a nuclear reactor and simplifies the multi-step design process by direct coupling with thermal-hydraulics and structural mechanics calculations. Currently there are three solvers for the neutron transport code incorporated in UNIC: PN2ND, SN2ND, and MOCFE. PN2ND is based on a second-order even-parity spherical harmonics discretization of the transport equation and its primary target area of use is the existing homogenization approaches that are prevalent in reactor physics. MOCFE is based upon the method of characteristics applied to an unstructured finite element mesh and its primary target area of use is the fine grained nature of the explicit geometrical problems …

All of the work conducted under the auspices of DE-FC02-01ER25473 was characterized by exceptionally close collaboration with researchers at the Lawrence Berkeley National Laboratory (LBNL). This included having one of my graduate students - Sarah Williams - spend the summer working with Dr. Ann Almgren a staff scientist in the Center for Computational Sciences and Engineering (CCSE) which is a part of the National Energy Research Supercomputer Center (NERSC) at LBNL. As a result of this visit Sarah decided to work on a problem suggested by Dr. John Bell the head of CCSE for her PhD thesis, which she finished in June 2007. Writing a PhD thesis while working at one of the University of California (UC) managed DOE laboratories is a long established tradition at the University of California and I have always encouraged my students to consider doing this. For example, in 2000 one of my graduate students - Matthew Williams - finished his PhD thesis while working with Dr. Douglas Kothe at the Los Alamos National Laboratory (LANL). Matt is now a staff scientist in the Diagnostic Applications Group in the Applied Physics Division at LANL. Another one of my graduate students - Christopher Algieri - who …

This is a more comprehensive report of the accelerator physics in the white paper 'PEP-X Light Source at SLAC'. A new light source called 'PEP-X' would reside in the 2.2-km PEP-II tunnel. It has a hybrid lattice where two of its six arcs contain DBA cells that provide a total of 30 straight sections for insertion device beam lines and the remaining arcs contain TME cells for an extremely low emittance. Using 90 meter damping wigglers the horizontal emittance at 4.5 GeV is further reduced to 0.1 nm-rad. Many collective effects including intra-beam scattering, Touschek lifetime, and fast ion instability are studied. We expect that PEP-X will produce photon beams having brightnesses near 10{sup 22} (ph/s/mm{sup 2}/mrad{sup 2}/0.1% BW) at 10 keV and 10{sup 21} at 35 keV.

Several new physics scenarios can lead to monojet signatures at the LHC. If such events are observed above the Standard Model background it will be important to identify their origin. In this paper we compare and contrast these signatures as produced in two very different pictures: vector or scalar unparticle production in the scale-invariant/conformal regime and graviton emission in the Arkani-Hamed, Dimopoulos and Dvali extra-dimensional model. We demonstrate that these two scenarios can be distinguished at the LHC for a reasonable range of model parameters through the shape of their respective monojet and/or missing E{sub T} distributions.

Objectives. The overall objective of this application is to develop novel technologies for non-invasive imaging of adoptive stem cell-based therapies with positron emission tomography (PET) that would be applicable to human patients. To achieve this objective, stem cells will be genetically labeled with a PET-reporter gene and repetitively imaged to assess their distribution, migration, differentiation, and persistence using a radiolabeled reporter probe. This new imaging technology will be tested in adoptive progenitor cell-based therapy models in animals, including: delivery pro-apoptotic genes to tumors, and T-cell reconstitution for immunostimulatory therapy during allogeneic bone marrow progenitor cell transplantation. Technical and Scientific Merits. Non-invasive whole body imaging would significantly aid in the development and clinical implementation of various adoptive progenitor cell-based therapies by providing the means for non-invasive monitoring of the fate of injected progenitor cells over a long period of observation. The proposed imaging approaches could help to address several questions related to stem cell migration and homing, their long-term viability, and their subsequent differentiation. The ability to image these processes non-invasively in 3D and repetitively over a long period of time is very important and will help the development and clinical application of various strategies to control and direct stem cell …
