Photosynthesis is the biological process that converts solar energy into chemical energy. Elucidation of the mechanisms of photosynthetic energy conversion at a molecular level is fundamentally important for understanding the biology of photosynthetic organisms, for optimizing biological solar fuels production, and for developing biologically inspired approaches to solar energy conversion. The 2011 Gordon Conference on Photosynthesis will present cutting-edge research focusing on the biochemical aspects of photosynthesis, including: (1) structure, assembly, and function of photosynthetic complexes; (2) the mechanism of water splitting by PSII; (3) light harvesting and quenching; (4) alternative electron transport pathways; (5) biosynthesis of pigments and cofactors; and (6) improvement of photosynthesis for bioenergy and food production. Reflecting the interdisciplinary nature of photosynthesis research, a diverse group of invited speakers will represent a variety of scientific approaches to investigate photosynthesis, such as biochemistry, molecular genetics, structural biology, systems biology, and spectroscopy. Highly interactive poster sessions provide opportunities for graduate students and postdocs to present their work and exchange ideas with leaders in the field. One of the highlights of the Conference is a session featuring short talks by junior investigators selected from the poster presentations. The collegial atmosphere of the Photosynthesis GRC, with programmed discussion sessions as …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses GAO's report on U.S. efforts to address terrorist safe havens. Terrorist safe havens provide security for terrorists, allowing them to train recruits and plan operations. U.S. officials have concluded that various terrorist incidents demonstrate the dangers emanating from terrorist safe havens, such as the November 2008 attacks in Mumbai, India, planned, in part, from safe havens in Pakistan, and the attempted airliner bombing on December 25, 2009, planned from safe havens in Yemen. The discovery of Osama Bin Laden in a compound in Pakistan, from which, according to U.S. officials, he played an active role in al Qaeda focused on attacking the United States, makes this hearing particularly timely. The testimony today focuses on (1) U.S. national strategies related to addressing terrorist safe havens, (2) terrorist safe havens identified by the Department of State (State) and the threats emanating from these havens, and (3) the extent to which the U.S. government has identified efforts to deny terrorists safe havens."

Testimony issued by the Government Accountability Office with an abstract that begins "The Compact of Free Association between the United States and the Republic of Palau, which entered into force in 1994, provided for several types of assistance aimed at promoting Palau's self-sufficiency and economic advancement. Included were 15 years of direct assistance to the Palau government; contributions to a trust fund meant to provide Palau $15 million each year from 2010 through 2044; construction of a road system, known as the Compact Road; and federal services such as postal, weather, and aviation. U.S. agencies also provided discretionary federal programs related to health, education, and infrastructure. In 2008, GAO projected total assistance from 1994 though 2009 would exceed $852 million. In September 2010, the United States and Palau signed an agreement (the Agreement) that would, among other things, provide for additional assistance to Palau and modify its trust fund. This statement describes (1) the Agreement's provisions for economic assistance to Palau, (2) its impact on the trust fund's likelihood of sustaining scheduled payments through 2044, and (3) the projected role of U.S. assistance in Palau government revenues. GAO reviewed the Agreement; examined Palau's recent single audit reports and budget projections; …

Correspondence issued by the Government Accountability Office with an abstract that begins "This report responds to section 322 of the Duncan Hunter National Defense Authorization Act for Fiscal Year 2009. Section 322 required the Secretary of Defense to contract for a study on the capability and efficiency of the depots of the Department of Defense (DOD) to provide the logistics capabilities and capacity necessary for national defense. DOD placed a task order under an existing contract with LMI, Inc. (LMI) to complete the study, which was to address a range of issues specified in section 322. As required by section 322, the task order specified that the contractor submit an interim report on its study to the Senate and House Committees on Armed Services not later than 1 year after the commencement of the study and a final report not later than 22 months after the date on which the Secretary of Defense enters into the contract. LMI submitted its interim report, containing background information and summary data on the DOD depot maintenance enterprise, to the Committees on Armed Services in December 2009. The final report, containing conclusions and recommendations, was provided to the Committees on Armed Services in February …

Testimony issued by the Government Accountability Office with an abstract that begins "In the Energy Independence and Security Act of 2007, Congress mandated higher vehicle fuel economy by model year 2020 and established the Advanced Technology Vehicles Manufacturing (ATVM) loan program in the Department of Energy (DOE). ATVM is to provide up to $25 billion in loans for more fuel-efficient vehicles and components. Congress also provided $7.5 billion to pay the required credit subsidy costs--the government's estimated net long-term cost, in present value terms, of the loans. This testimony is based on GAO's February 2011 report on the ATVM loan program (GAO-11-145). It discusses (1) steps DOE has taken to implement the program, (2) progress in awarding loans, (3) how the program is overseeing the loans, and (4) the extent to which DOE can assess progress toward its goals."

Correspondence issued by the Government Accountability Office with an abstract that begins "The Federal Employees Pay Comparability Act (FEPCA) of 1990 established locality pay to achieve pay comparability between federal and nonfederal jobs within the United States. Because FEPCA established pay localities only for areas within the United States, federal employees permanently stationed overseas, including members of the Foreign Service, did not receive locality pay. As the Washington, D.C., locality rate grew to over 24 percent in 2010, the pay gap between federal employees who receive locality pay and those who do not widened considerably. To close this gap, the fiscal year 2009 Supplemental Appropriations Act granted the Department of State (State) temporary authority to provide locality pay at the Washington, D.C., rate, also known as Overseas Comparability Pay, to Foreign Service personnel posted overseas. State is implementing this pay in three phases. Currently, Foreign Service personnel serving overseas receive 16.52 percent comparability pay, approximately twothirds of the Washington, D.C., locality rate. State had planned to implement the third and final phase of comparability pay, raising it to 24.22 percent, in August 2011. However, these plans have been delayed by the administration's freeze on federal salaries and the passage of …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the training efforts of the U.S. Department of State's (State) Bureau of Diplomatic Security (Diplomatic Security). The testimony is based on our report, which is being released today. Diplomatic Security is responsible for the protection of people, information, and property at over 400 embassies, consulates, and domestic locations and, as we reported in previous testimony, experienced a large growth in its budget and personnel over the last decade. Diplomatic Security trains its workforce and others to address a variety of threats, including crime, espionage, visa and passport fraud, technological intrusions, political violence, and terrorism. To meet its training needs, Diplomatic Security relies primarily on its Diplomatic Security Training Center (DSTC), which is an office of Diplomatic Security's Training Directorate and is the primary provider of Diplomatic Security training. Diplomatic Security's training budget grew steadily from fiscal years 2006 to 2010--increasing from approximately $24 million in fiscal year 2006 to nearly $70 million in fiscal year 2010. In fiscal year 2010, DSTC conducted 342 sessions of its 61 courses and trained 4,739 students. Our prior work identified the challenges that Diplomatic Security experienced as a result …

Testimony issued by the Government Accountability Office with an abstract that begins "The Social Security Administration's (SSA) Disability Insurance (DI) program paid almost $123 billion in benefits in fiscal year 2010 to more than 10 million workers and dependents. The program has grown rapidly in recent years and is poised to grow further as the baby boom generation ages. GAO examined (1) what is known about the extent SSA makes work-related overpayments to, and recovers overpayments from, DI beneficiaries, and (2) SSA's policies and procedures for work continuing disability reviews (work CDRs) and potential DI program vulnerabilities that may contribute to overpayments to beneficiaries who have returned to work. To answer these questions, GAO reviewed work CDR policies and procedures, interviewed SSA headquarters and processing center officials, and visited 4 of 8 processing centers. We reviewed a random nongeneralizable sample of 60 CDR case files across those 4 centers to ensure we had a wide range of cases for our review (15 cases from each). These 4 centers received almost 80 percent of all work CDRs from SSA's Internal Revenue Service enforcement data match in fiscal year 2009."

Testimony issued by the Government Accountability Office with an abstract that begins "While federal grant funding has been increasing, long-standing concerns remain about the federal government's grants management and the lack of effective oversight tools to reasonably assure that grants are used for their intended purposes and that risks of fraud, waste, and abuse are minimized. GAO has issued a range of reports raising concerns about the risks and vulnerabilities related to grants management and oversight. The Administration recognizes these concerns. It included improving grants management as a part of its initiative to eliminate waste in the U.S. government and has various efforts underway to improve grants oversight and accountability. This testimony addresses the (1) significance of federal grant funding, (2) risks and vulnerabilities in key controls in the federal grant life cycle, and (3) improvements needed to make the single audit process an effective accountability mechanism. This testimony is primarily based on prior GAO work that reviewed grant accountability and the single audit process."

Testimony issued by the Government Accountability Office with an abstract that begins "The federal government holds more than 45,000 underutilized properties that cost nearly $1.7 billion annually to operate, yet significant obstacles impede efforts to close, consolidate, or find other uses for these properties. GAO has designated federal real property management as a high-risk area, in part because of the number and cost of these properties. The Office of Management and Budget (OMB) is responsible for reviewing federal agencies' progress in real property management. In 2007, GAO recommended that OMB assist agencies by developing an action plan to address key obstacles associated with decisions related to unneeded real property, including stakeholder influences. In May 2011, the administration proposed legislation, referred to as the Civilian Property Realignment Act (CPRA), to, among other things, establish a legislative framework for disposing of and consolidating civilian real property and that could help limit stakeholder influences in real property decision making. This statement identifies (1) progress the government has made toward addressing obstacles to federal real property management, (2) some of the challenges that remain and how CPRA may be responsive to those challenges, and (3) key elements of the Department of Defense's (DOD) base …

Testimony issued by the Government Accountability Office with an abstract that begins "The National Flood Insurance Program (NFIP) has been on GAO's high-risk list since 2006, when the program had to borrow from the U.S. Treasury to cover losses from the 2005 hurricanes. The outstanding debt is $17.8 billion as of June 2011. This sizeable debt, plus operational and management challenges that GAO has identified at the Federal Emergency Management Agency (FEMA), which administers NFIP, have combined to keep the program on the high-risk list. NFIP's need to borrow to cover claims in years of catastrophic flooding has raised concerns about the program's long-term financial solvency. This testimony (1) discusses ways to place NFIP on a sounder financial footing in light of public policy goals for federal involvement in natural catastrophe insurance and (2) highlights operational and management challenges at FEMA that affect the program. In preparing this statement, GAO relied on its past work on NFIP, including a June 2011 report on FEMA's management of NFIP, which focused on its planning, policies, processes, and systems. The management review included areas such as strategic and human capital planning, acquisition management, and intra-agency collaboration."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses GAO's campus recruitment program. As an organization committed to having a high-performing, diverse workforce, GAO places great importance on attracting, hiring, training, and retaining employees with the skills needed to support GAO's mission to serve Congress and the American public. GAO has a multi-disciplinary workforce, with most staff having backgrounds in public policy, public administration, law, business, computer science, accounting, social sciences, or economics. While our current and future hiring will be shaped by today's constrained budget environment, over the past 5 years, on average, GAO has hired about 300 employees each year. The majority of these hires were for analyst and analyst-related positions at the entry level. GAO also has a robust paid student intern program each year. Many of these interns return as entry-level analysts. Having a strong campus recruitment program has played a key role in attracting highly qualified candidates for our permanent and intern positions and building our workforce. In response to congressional request, the remarks will focus on (1) the strong partnerships developed through our campus recruitment program, (2) recent actions GAO has taken to enhance the program and the …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses H.R. 1495, the Gold Reserve Transparency Act of 2011. This proposed legislation, which was recently referred to the Subcommittee on Domestic Monetary Policy and Technology, House Committee on Financial Services, provides for an audit of the gold reserves of the United States. Specifically, the bill calls for the Secretary of the Treasury to conduct and complete, not later than 6 months after passage of the act, a full assay, inventory, and audit of gold reserves of the United States at the place or places where such reserves are kept, together with an analysis of the sufficiency of the measures taken for the security of such reserves. The bill also calls for the Government Accountability Office (GAO) to review the results of such assay, inventory, audit, and analysis and, not later than 9 months after passage of the act, prepare and transmit to the Congress a report of GAO's findings together with the results of the work performed by the Secretary of the Treasury. This testimony focuses on (1) the reported holdings of gold reserves of the United States as of September 30, 2010; (2) past …

Correspondence issued by the Government Accountability Office with an abstract that begins "Comparative effectiveness research (CER) is research comparing different interventions and strategies to prevent, diagnose, treat, and monitor health conditions. The American Recovery and Reinvestment Act of 2009 (Recovery Act) appropriated $1.1 billion to the Department of Health and Human Services (HHS) specifically for CER, including $400 million to the Secretary of HHS, $300 million to the Agency for Healthcare Research and Quality (AHRQ), and $400 million to the National Institutes of Health (NIH). The Recovery Act required that these funds be obligated by September 30, 2010. For grants and cooperative agreements, funds are drawn down by recipients on an as-needed basis in accordance with the objectives of the project. For contracts, as milestones are met, invoices are submitted to HHS for payments for goods and services provided under the contract. Additionally, the Patient Protection and Affordable Care Act (PPACA) directed AHRQ to disseminate the findings of CER published by the Patient-Centered Outcomes Research Institute (PCORI) and other related government-funded research in consultation with NIH. PPACA established a trust fund to support PCORI's mission and specified that percentages of this trust fund be provided to the Secretary of HHS …

Correspondence issued by the Government Accountability Office with an abstract that begins "This letter responds to the mandate contained in Section 1312(c) of the Small Business Jobs Act of 2010, for GAO to conduct a study of the Small Business Administration's (SBA) Procurement Center Representatives (PCR) and Commercial Market Representatives (CMR), including ways to improve their effectiveness. To fulfill this mandate, we provided congressional staff a briefing on the results of this work in meetings with them on March 22, 23, and 24, 2011. Each year, the federal government awards hundreds of billions of dollars in contracts for goods and services--more than $500 billion in fiscal year 2010 alone. It uses this buying power to maximize procurement opportunities for small businesses through long-standing policies such as set-asides and requiring large contractors to set goals for using small business subcontractors. SBA's PCRs and CMRs play an important role in helping ensure that small businesses gain access to contracting and subcontracting opportunities. In particular, a PCR's key responsibilities include reviewing proposed agency contract events--such as potentially bundled or consolidated contracts--and making set-aside recommendations to agency contracting officers (through informal and formal means), reviewing agency small business programs (surveillance reviews), and counseling small …

Testimony issued by the Government Accountability Office with an abstract that begins "The National Museum of the American Indian Act of 1989 (NMAI Act), as amended in 1996, generally requires the Smithsonian Institution to inventory and identify the origins of its Indian and Native Hawaiian human remains and objects placed with them (funerary objects) and repatriate them to culturally affiliated Indian tribes upon request. According to the Smithsonian, two of its museums--the American Indian and the Natural History Museums--have items that are subject to the NMAI Act. The Native American Graves Protection and Repatriation Act (NAGPRA), enacted in 1990, includes similar requirements for federal agencies and museums. The National NAGPRA office, within the Department of the Interior's National Park Service, facilitates the governmentwide implementation of NAGPRA. Each act requires the establishment of a committee to monitor and review repatriation activities. GAO's testimony is based on its July 2010 report on NAGPRA implementation (GAO-10-768) and its May 2011 report on Smithsonian repatriation (GAO-11-515). The testimony focuses on the extent to which key federal agencies have complied with NAGPRA's requirements and the extent to which the Smithsonian has fulfilled its repatriation requirements."

Correspondence issued by the Government Accountability Office with an abstract that begins "Section 8102 of the Department of Defense (DOD) and Full-Year Continuing Appropriations Act for fiscal year 2011 directed us to evaluate the effect on national security resulting from the section's requirements. These requirements, as well as those previously included in Section 8116 of the DOD Appropriations Act for fiscal year 2010, prohibit DOD's use of funds appropriated by the respective acts for any contract over $1 million unless the contractor agrees not to use or enforce mandatory arbitration agreements to resolve specified employee claims, such as those under Title VII of the Civil Rights Act of 1964. These statutes also provide that the Secretary of Defense can waive the application of these restrictions on mandatory arbitration to avoid harm to U.S. national security interests."

Correspondence issued by the Government Accountability Office with an abstract that begins "In November 2010, we issued our report on the results of our audit of the financial statements of the Internal Revenue Service (IRS) as of, and for the fiscal years ending, September 30, 2010, and 2009, and on the effectiveness of its internal control over financial reporting as of September 30, 2010. We also reported our conclusions on IRS's compliance with selected provisions of laws and regulations and on whether IRS's financial management systems substantially comply with the requirements of the Federal Financial Management Improvement Act of 1996. In March 2011, we issued a report on information security issues identified during our fiscal year 2010 audit, along with associated recommendations for corrective actions. The purpose of this report is to present internal control issues identified during our audit of IRS's fiscal year 2010 financial statements for which we do not already have any recommendations outstanding. While two of these issues contributed to a significant deficiency in internal control discussed in our report on the results of our fiscal year 2010 financial statement audit, they all warrant IRS management's attention. This report provides 29 recommendations to address the internal …

Correspondence issued by the Government Accountability Office with an abstract that begins "To help defray out-of-pocket prescription drug costs for limited or low-income Medicare beneficiaries, the Medicare Part D outpatient prescription drug program offers a low-income subsidy (LIS) for eligible beneficiaries. In 2010, about 9.4 million beneficiaries received the LIS--about 40 percent of the approximately 23 million Medicare Part D beneficiaries in that year. Most of the LIS beneficiaries received the full LIS, thus paying no premiums or deductibles as long as they enrolled in so-called "benchmark" stand-alone prescription drug plans (PDP). Benchmark PDPs are those plans with premiums at or below a specified benchmark for a given geographic region, calculated by the Centers for Medicare & Medicaid Services (CMS), the agency within the Department of Health and Human Services (HHS) that administers the Medicare program. Full LIS beneficiaries may also enroll in other Part D plans--either nonbenchmark PDPs or Medicare Advantage prescription drug plans (MAPD)-- but must pay any difference between the premium of the plan in which they choose to enroll and the benchmark for their region. Because plan premiums can change from year to year and because CMS recalculates the premium benchmarks annually, some PDPs may be …
