Global HIV/AIDS: A More Country-Based Approach Could Improve Allocation of PEPFAR Funding
A letter report issued by the Government Accountability Office with an abstract that begins "The President's Emergency Plan for AIDS Relief (PEPFAR) provides assistance for combating HIV/AIDS in 15 focus countries and elsewhere, with global targets for prevention, treatment, and care. The U.S. Leadership Against HIV/AIDS, TB and Malaria Act of 2003, which authorizes the $15 billion program, contains directives to guide the Office of the U.S. Global AIDS Coordinator's (OGAC) allocation of this funding. The act expires in September 2008. The President announced his intention to ask Congress to authorize $30 billion for these efforts for the next 5 years. In 2007, the Institute of Medicine (IOM) recommended eliminating the directives. GAO was asked to describe (1) the views of HIV/AIDS experts on these directives, (2) an alternative approach to allocating funds, and (3) potential challenges related to this approach. GAO interviewed 22 experts, surveyed PEPFAR officials in the 15 focus countries, and reviewed pertinent documentation."

Management Report: Improvements Needed in SEC's Internal Controls and Accounting Procedures
Correspondence issued by the Government Accountability Office with an abstract that begins "On November 14, 2008, we issued our opinion on the U.S. Securities and Exchange Commission's (SEC) fiscal years 2008 and 2007 financial statements. We also issued our opinion on the effectiveness of SEC's internal control over financial reporting (including safeguarding of assets) and over compliance as of September 30, 2008, and our evaluation of SEC's compliance with selected provisions of laws and regulations during fiscal year 2008. The purpose of this report is to present issues identified during our fiscal year 2008 audit of SEC's internal controls and accounting procedures and to recommend actions to address these issues. Accordingly, in this report we are making 19 recommendations to SEC to strengthen internal controls and accounting procedures. These recommendations are in addition to 24 remaining recommendations included in prior year audits of SEC's financial statements that still need to be fully addressed."

First Responders: Much Work Remains to Improve Communications Interoperability
A letter report issued by the Government Accountability Office with an abstract that begins "As the first to respond to natural disasters, domestic terrorism, and other emergencies, public safety agencies rely on timely communications across multiple disciplines and jurisdictions. It is vital to the safety and effectiveness of first responders that their electronic communications systems enable them to communicate with whomever they need to, when they need to, and when they are authorized to do so. GAO was asked to determine, among other things, (1) the extent to which Department of Homeland Security (DHS) funding and technical assistance has helped to improve interoperable communications in selected states and (2) the progress that has been made in the development and implementation of interoperable communications standards. To address these objectives, GAO reviewed grant information, documentation of selected states' and localities' interoperability projects, and standards documents."

Appointment and Qualifications of U.S. Marshals
Correspondence issued by the General Accounting Office with an abstract that begins "The U.S. Marshal Service was created by the first Congress in the Judiciary Act of 1789. U.S. Marshals were placed in each federal judicial district and were given broad authority to support the federal courts and to carry out all lawful orders issued by judges, Congress, and the President. Early duties of U.S. Marshals included taking the census, distributing presidential proclamations, protecting the borders, and making arrests. Beginning in the late nineteenth century, some responsibilities of U.S. Marshals were transferred to newly created federal agencies, including the U.S. Census Bureau, Immigration and Naturalization Service, and Federal Bureau of Investigation. Today, the primary responsibilities of U.S. Marshals include protecting federal judges and witnesses, transporting federal prisoners, apprehending federal fugitives, and managing assets seized from criminal enterprises. We obtained information on the (1) U.S. Marshals' appointment process and, for comparison, the processes used by the Bureau of Alcohol, Tobacco, and Firearms (ATF); Drug Enforcement Administration (DEA); and Internal Revenue Service-Criminal Investigation (IRS-CI) to select senior field supervisors; (2) experience, education and diversity of U.S. Marshalls and senior field supervisors at the ATF, DEA, and IRS-CI; (3) authority of the Director …

Geostationary Operational Environmental Satellites: Acquisition Is Under Way, but Improvements Needed in Management and Oversight
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Commerce's National Oceanic and Atmospheric Administration (NOAA), with the aid of the National Aeronautics and Space Administration (NASA), plans to procure the next generation of geostationary operational environmental satellites, called the Geostationary Operational Environmental Satellite-R series (GOES-R). GOES-R is to replace the current series of satellites, which will likely begin to reach the end of their useful lives in approximately 2014. This series is considered critical to the United States' ability to maintain the continuity of data required for weather forecasting through the year 2028. GAO was asked to (1) determine the status of the GOES-R program, (2) evaluate whether plans for the acquisition address problems experienced on similar programs, and (3) determine whether NOAA's plan will be adequate to support current data requirements. To do so, GAO analyzed contractor and program data and interviewed officials from NOAA and NASA."

Defense Management: Continuing Questionable Reliance on Commercial Contracts to Demilitarize Excess Ammunition When Unused, Environmentally Friendly Capacity Exists at Government Facilities
Correspondence issued by the General Accounting Office with an abstract that begins "In April 2001, we reported that the Army Materiel Command's guidance required that 50 percent of the excess conventional ammunition demilitarization budget--a figure for which we did not find any analytical basis--be set aside for commercial firms that use environmentally friendly demilitarization processes. This resulted in the retention and underutilization of environmentally friendly demilitarization capabilities at government facilities and in additional program costs. We thus recommended that the Department of Defense (DOD) develop a plan in consultation with Congress that included procedures for assessing the appropriate mix of government and commercial sector capacity needed to demilitarize excess ammunition. Our intent was to have DOD reexamine the cost-effectiveness of using commercial versus government facilities to demilitarize excess ammunition. Over the past several months we have conducted work to determine the specific actions taken to implement our recommendation. We made extensive use of our prior work as a baseline to compare the changes in demilitarization capacity and utilization at government-owned facilities since our prior report. We conducted our analysis of DOD's demilitarization program in accordance with generally accepted government auditing standards. The purpose of this letter is to note that …

Tactical Aircraft: DOD Needs a Joint and Integrated Investment Strategy
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) plans to invest $109 billion in its tactical air forces between 2007 and 2013. Long term, DOD plans to replace aging legacy aircraft with fewer, more expensive but more capable and stealthy aircraft. Recapitalizing and modernizing tactical air forces within today's constrained budget environment is a formidable challenge. DOD has already incurred substantial cost and schedule overruns in its acquisition of new systems, and further delays could require billions of dollars in additional investments to keep legacy aircraft capable and sustainable. Because of the large investments and risk, GAO was asked to review investment planning for tactical aircraft. This report describes the current status of DOD's new tactical aircraft acquisition programs; identifies current impacts on legacy aircraft modernization programs and retirement schedules; and assesses DOD's overall investment plan for tactical aircraft."

Military Training: DOD Approach to Managing Encroachment on Training Ranges Still Evolving
Testimony issued by the General Accounting Office with an abstract that begins "DOD faces growing challenges in carrying out realistic training at installations and training ranges--land, air, and sea--because of encroachment by outside factors. These include urban growth, competition for radio frequencies or airspace, air or noise pollution, unexploded ordnance and munition components, endangered species habitat, and protected marine resources. Building on work reported on in 2002, GAO assessed (1) the impact of encroachment on training ranges, (2) DOD's efforts to document the effect on readiness and cost, and (3) DOD's progress in addressing encroachment."

Tactical Aircraft: Status of the F/A-22 Program
Testimony issued by the General Accounting Office with an abstract that begins "The Air Force is developing the F/A-22 aircraft to replace its fleet of F-15 air superiority aircraft. The F/A-22 is designed to be superior to the F-15 by being capable of flying at higher speeds for longer distances, less detectable, and able to provide the pilot with substantially improved awareness of the surrounding situation. The National Defense Authorization Act for Fiscal Year 1998 requires us to annually assess the F/A-22 development program and determine whether the program is meeting key performance, schedule, and cost goals. We have issued six of these annual reports to Congress. We have also reported on F/A-22 production program costs over the last 3 years. Most recently, we reported on F/A-22 production and development in February and March 2003 respectively. This testimony summarizes our work on the F/A-22 program, covering performance, cost, and scheduling issues."

Federal Advisory Committee Act: Issues Related to the Independence and Balance of Advisory Committees
Testimony issued by the Government Accountability Office with an abstract that begins "Because advisory committees provide input to federal decision makers on significant national issues, it is essential that their membership be, and be perceived as being, free from conflicts of interest and balanced as a whole. The Federal Advisory Committee Act (FACA) was enacted in 1972, in part, because of concerns that special interests had too much influence over federal agency decision makers. The General Services Administration (GSA) develops guidance on establishing and managing FACA committees. The Office of Government Ethics (OGE) develops regulations and guidance for statutory conflict-of- interest provisions that apply to some advisory committee members. As requested, this testimony discusses key findings and conclusions in our 2004 report, Federal Advisory Committees: Additional Guidance Could Help Agencies Better Ensure Independence and Balance; GAO's recommendations to GSA and OGE and their responses; and potential changes to FACA that could better ensure the independence and balance of advisory committees. For our 2004 work, we reviewed policies and procedures issued by GSA, OGE, and nine federal agencies that sponsor many committees. For this testimony, we obtained information from GSA and OGE on actions they have taken to implement our recommendations; …

Global HIV/AIDS: Survey of PEPFAR Country Team Officials (GAO-08-534SP), an E-supplement to GAO-08-480
Other written product issued by the Government Accountability Office with an abstract that begins "This is the E-supplement to GAO-08-480. This document presents the results of our electronic survey of 41 U.S. officials implementing PEPFAR funding in 15 focus countries (country team officials). We conducted the survey to identify potential challenges to implementing an alternative approach, developed from HIV/AIDS experts' suggestions, to allocating funds for the next 5-year phase of PEPFAR. The survey respondents included the Centers for Disease Control and Prevention (CDC) Chief of Party, the U.S. Agency for International Development (USAID) health team leader, and the PEPFAR coordinator in each of the 15 focus countries. The questions in our survey were intended to obtain information on country teams' experiences with setting targets, selecting interventions, and using cost information. Of the 41 country team officials, 38 responded to the survey, resulting in a survey response rate of 93 percent. This document presents results from all closed-ended survey questions but does not include narrative responses that we received. A more detailed discussion of our scope and methodology is contained in our report Global HIV/AIDS: A More Country-Based Approach Could Improve Allocation of PEPFAR Funding (GAO-08-480).

General Services Administration: Factors Affecting the Construction and Operating Costs of Federal Buildings
Testimony issued by the General Accounting Office with an abstract that begins "The General Services Administration (GSA) has responsibility for more than 8,000 owned and leased buildings nationwide, together encompassing about 338 million square feet of space. Understanding construction and operating costs for these buildings is important, as the increased federal budget deficit has led to intensified competition for federal resources and recent events have highlighted security needs. GAO examined (1) factors that have affected GSA's construction, leasing, and operating costs and (2) our designation of federal real property as a high-risk area."

Combating Terrorism: Intergovernmental Cooperation in the Development of a National Strategy to Enhance State and Local Preparedness
Testimony issued by the General Accounting Office with an abstract that begins "Federal, state, and local governments share responsibility for terrorist attacks. However, local government, including police and fire departments, emergency medical personnel, and public health agencies, is typically the first responder to an incident. The federal government historically has provided leadership, training, and funding assistance. In the aftermath of September 11, for instance, one-quarter of the $40 billion Emergency Response Fund was earmarked for homeland security, including enhancing state and local government preparedness. Because the national security threat is diffuse and the challenge is highly intergovernmental, national policymakers must formulate strategies with a firm understanding of the interests, capacity, and challenges facing those governments. The development of a national strategy will improve national preparedness and enhance partnerships between federal, state, and local governments. The creation of the Office of Homeland Security is an important and potentially significant first step. The Office of Homeland Security's strategic plan should (1) define and clarify the appropriate roles and responsibilities of federal, state, and local entities; (2) establish goals and performance measures to guide the nation's preparedness efforts; and (3) carefully choose the most appropriate tools of government to implement the national strategy …

Internal Revenue Service: Progress Continues But Serious Management Challenges Remain
Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the management challenges that continue to face the Internal Revenue Service (IRS). These challenges include (1) computer security, (2) financial management, (3) organizational modernization and performance management, and (4) business systems modernization management. IRS must make progress in all four areas to improve the agency's efficiency and to significantly improve service to taxpayers. IRS has taken important steps in all of these areas, but significant obstacles remain. In the area of computer security, IRS corrected many previously reported weaknesses and is launching a computer security management program that should help it manage its risks in this area. However, serious weaknesses persist that could impair IRS' ability to perform vital functions. In financial management, IRS was able to prepare financial statements this year that received an unqualified opinion. However, this achievement came through the use of substantial, costly, and time-consuming processes to work around IRS' system deficiencies. IRS has reorganized into four taxpayer-focused divisions and has developed a performance management approach consistent with management principles contained in the IRS Restructuring and Reform Act and the Government Performance and Results Act. However, much work remains to be …

Defense Critical Infrastructure: DOD's Risk Analysis of Its Critical Infrastructure Omits Highly Sensitive Assets
Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) relies on a global network of critical physical and cyber infrastructure to project, support, and sustain its forces and operations worldwide. The incapacitation, exploitation, or destruction of one or more of its assets would seriously damage DOD's ability to carry out its core missions. To identify and help assure the availability of this mission-critical infrastructure, in August 2005, DOD established the Defense Critical Infrastructure Program (DCIP), assigning overall responsibility for the program to the Assistant Secretary of Defense for Homeland Defense and Americas' Security Affairs (ASD[HD&ASA]). Since 2006, ASD(HD&ASA) has collaborated with the Joint Staff to compile a list of all DOD- and non-DOD-owned infrastructure essential to accomplish the National Defense Strategy. Each critical asset on the list must undergo a vulnerability assessment, which identifies weaknesses in relation to potential threats and suggests options to address those weaknesses. Data and material designated as Sensitive Compartmented Information (SCI) or associated with Special Access Programs (SAP) are among the nation's most valued and closely guarded assets, and DOD faces inherent challenges in incorporating them into DCIP. The number of individuals authorized to access SCI and …

Ambient-temperature Conditioning as a Probe of Double-C Transformation Mechanisms in Pu-2.0 at. % Ga
The gallium-stabilized Pu-2.0 at. % Ga alloy undergoes a partial or incomplete low-temperature martensitic transformation from the metastable {delta} phase to the gallium-containing, monoclinic {alpha}{prime} phase near -100 C. This transformation has been shown to occur isothermally and it displays anomalous double-C kinetics in a time-temperature-transformation (TTT) diagram, where two nose temperatures anchoring an upper- and lower-C describe minima in the time for the initiation of transformation. The underlying mechanisms responsible for the double-C behavior are currently unresolved, although recent experiments suggest that a conditioning treatment--wherein, following an anneal at 375 C, the sample is held at a sub-anneal temperature for a period of time--significantly influences the upper-C of the TTT diagram. As such, elucidating the effects of the conditioning treatment upon the {delta} {yields} {alpha}{prime} transformation can provide valuable insights into the fundamental mechanisms governing the double-C kinetics of the transition. Following a high-temperature anneal, a differential scanning calorimeter (DSC) was used to establish an optimal conditioning curve that depicts the amount of {alpha}{prime} formed during the transformation as a function of conditioning temperature for a specified time. With the optimal conditioning curve as a baseline, the DSC was used to explore the circumstances under which the effects of …

Preparation of Size-tunable, Highly Monodisperse PVP-Protected Pt-nanoparticles by Seed-mediated Growth
We demonstrate a preparative method which produces highly-monodisperse Pt-nanoparticles of tunable size without the external addition of seed particles. Hexachloroplatinic acid is dosed slowly to an ethylene glycol solution at 120 C and reduced in the presence of a stabilizing polymer poly-N-vinylpyrollidone (PVP). Slow addition of the Pt-salt first will first lead to the formation of nuclei (seeds) which then grow further to produce larger particles of any desired size between 3 and 8nm. The amount of added hexachloroplatinic acid precursor controls the size of the final nanoparticle product. TEM was used to determine size and morphology and to confirm the crystalline nature of the nanoparticles. Good reproducibility of the technique was demonstrated. Above 7nm, the particle shape and morphology changes suddenly indicating a change in the deposition selectivity of the Pt-precursor from (100) towards (111) crystal faces and breaking up of larger particles into smaller entities.

ARCHITECTURE OF A CHARGE-TRANSFER STATE REGULATING LIGHT HARVESTING IN A PLANT ANTENNA PROTEIN
Energy-dependent quenching of excess absorbed light energy (qE) is a vital mechanism for regulating photosynthetic light harvesting in higher plants. All of the physiological characteristics of qE have been positively correlated with charge-transfer between coupled chlorophyll and zeaxanthin molecules in the light-harvesting antenna of photosystem II (PSII). In this work, we present evidence for charge-transfer quenching in all three of the individual minor antenna complexes of PSII (CP29, CP26, and CP24), and we conclude that charge-transfer quenching in CP29 involves a de-localized state of an excitonically coupled chlorophyll dimer. We propose that reversible conformational changes in CP29 can `tune? the electronic coupling between the chlorophylls in this dimer, thereby modulating the energy of the chlorophylls-zeaxanthin charge-transfer state and switching on and off the charge-transfer quenching during qE.

Chemical Kinetic Modeling of Hydrogen Combustion Limits
A detailed chemical kinetic model is used to explore the flammability and detonability of hydrogen mixtures. In the case of flammability, a detailed chemical kinetic mechanism for hydrogen is coupled to the CHEMKIN Premix code to compute premixed, laminar flame speeds. The detailed chemical kinetic model reproduces flame speeds in the literature over a range of equivalence ratios, pressures and reactant temperatures. A series of calculation were performed to assess the key parameters determining the flammability of hydrogen mixtures. Increased reactant temperature was found to greatly increase the flame speed and the flammability of the mixture. The effect of added diluents was assessed. Addition of water and carbon dioxide were found to reduce the flame speed and thus the flammability of a hydrogen mixture approximately equally well and much more than the addition of nitrogen. The detailed chemical kinetic model was used to explore the detonability of hydrogen mixtures. A Zeldovich-von Neumann-Doring (ZND) detonation model coupled with detailed chemical kinetics was used to model the detonation. The effectiveness on different diluents was assessed in reducing the detonability of a hydrogen mixture. Carbon dioxide was found to be most effective in reducing the detonability followed by water and nitrogen. The chemical …
