Defense Space Activities: DOD Needs to Further Clarify the Operationally Responsive Space Concept and Plan to Integrate and Support Future Satellites (open access)

Defense Space Activities: DOD Needs to Further Clarify the Operationally Responsive Space Concept and Plan to Integrate and Support Future Satellites

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) operational dependence on space has placed new and increasing demands on current space systems to meet commanders' needs. DOD's Operationally Responsive Space (ORS) concept is designed to more rapidly satisfy commanders' needs for information and intelligence during ongoing operations. Given the potential for ORS to change how DOD acquires and fields space capabilities to support the warfighter, this report discusses to what extent DOD (1) is developing ORS to support warfighter requirements and (2) has a plan that integrates ORS into existing DOD and intelligence community processes and architecture. GAO reviewed and analyzed ORS planning documents, the ORS concept of operations, and processes for meeting warfighter needs and also interviewed defense and intelligence community officials who are involved with the ORS concept."

Broadcasting to Cuba: Weaknesses in Contracting Practices Reduced Visibility into Selected Award Decisions

A letter report issued by the Government Accountability Office with an abstract that begins "The United States has long provided the Cuban people with alternative sources of news and information. As part of this effort, in December 2006 the International Broadcasting Bureau (IBB) awarded sole-source contracts to two Miami radio and television stations--Radio Mambi and TV Azteca--to provide additional broadcasting options. Additionally, the Office of Cuba Broadcasting (OCB) annually awards millions of dollars in contracts for talent services--writers, reporters, and technical support--needed to produce and broadcast news and entertainment programming. GAO evaluated the processes used to award (1) the Radio Mambi and TV Azteca broadcasting contracts, and (2) talent services contracts. We reviewed contract files and other documentation and interviewed program managers and contracting officers to determine the process used to award the two broadcasting contracts and a nongeneralizable selection of 37 talent services contracts."

Defense Acquisitions: Departmentwide Direction Is Needed for Implementation of the Anti-tamper Policy

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) invests billions of dollars on sophisticated weapon systems and technologies. These may be at risk of exploitation when exported, stolen, or lost during combat or routine missions. In an effort to minimize this risk, DOD developed an anti-tamper policy in 1999, calling for DOD components to implement anti-tamper techniques for critical technologies. In March 2004, GAO reported that program managers had difficulties implementing this policy, including identifying critical technologies. This follow-up report (1) describes recent actions DOD has taken to implement its anti-tamper policy and (2) identifies challenges facing program managers. GAO reviewed documentation on actions DOD has taken since 2004 to implement its anti-tamper policy, and interviewed officials from the Anti-Tamper Executive Agent's Office, the military services, other DOD components, and a cross-section of program offices."

National Response Framework: FEMA Needs Policies and Procedures to Better Integrate Non-Federal Stakeholders in the Revision Process

A letter report issued by the Government Accountability Office with an abstract that begins "Hurricane Katrina illustrated that effective preparation and response to a catastrophe requires a joint effort between federal, state, and local government. The Department of Homeland Security (DHS), through the Federal Emergency Management Agency (FEMA), is responsible for heading the joint effort. In January 2008, DHS released the National Response Framework (NRF), a revision of the 2004 National Response Plan (2004 Plan), the national preparation plan for all hazards. In response to the explanatory statement to the Consolidated Appropriations Act of 2008 and as discussed with congressional committees, this report evaluates the extent to which (1) DHS collaborated with non-federal stakeholders in revising and updating the 2004 Plan into the 2008 NRF and (2) FEMA has developed policies and procedures for managing future NRF revisions. To accomplish these objectives, GAO reviewed DHS and FEMA documents related to the revision process, analyzed the relevant statutes, and interviewed federal and non-federal officials who held key positions in the revision process."

Financial Audit: Federal Deposit Insurance Corporation Funds' 2007 and 2006 Financial Statements

A letter report issued by the Government Accountability Office with an abstract that begins "GAO is required to annually audit the financial statements of the Deposit Insurance Fund (DIF) and FSLIC Resolution Fund (FRF), which are administered by the Federal Deposit Insurance Corporation (FDIC). GAO is responsible for obtaining reasonable assurance about whether FDIC's financial statements for DIF and FRF are presented fairly in all material respects, in conformity with U.S. generally accepted accounting principles, and whether FDIC maintained effective internal control over financial reporting and compliance with laws and regulations. Also, GAO is responsible for testing FDIC's compliance with selected laws and regulations. Created in 1933 to insure bank deposits and promote sound banking practices, FDIC plays an important role in maintaining public confidence in the nation's financial system. In 1989, legislation to reform the federal deposit insurance system created three funds to be administered by FDIC: the Bank Insurance Fund (BIF) and the Savings Association Insurance Fund (SAIF), which protect bank and savings deposits, and FRF, which was created to close out the business of the former Federal Savings and Loan Insurance Corporation. In accordance with subsequent legislation passed in 2006, FDIC merged the BIF and SAIF into …

Medicare and Medicaid: CMS and State Efforts to Interact with the Indian Health Service and Indian Tribes (open access)

Medicare and Medicaid: CMS and State Efforts to Interact with the Indian Health Service and Indian Tribes

A letter report issued by the Government Accountability Office with an abstract that begins "By law, facilities funded by the Indian Health Service (IHS) may retain reimbursement from Medicare and Medicaid without an offsetting reduction in funding. Ensuring that IHS-funded facilities enroll individuals in--and obtain reimbursement from--Medicare and Medicaid can provide an important means of expanding the funding for health care services for the population served by IHS. The Centers for Medicare & Medicaid Services (CMS), the agency within the Department of Health and Human Services (HHS) that administers Medicare and oversees states' Medicaid programs, is required by Executive Order and HHS policy to consult with Indian tribes on policies that have tribal implications. This requirement is in recognition of the unique government-to-government relationship between the 562 federally recognized Indian tribes and the federal government. GAO was asked to (1) describe interactions between CMS and IHS, (2) examine mechanisms CMS uses to interact and consult with Indian tribes, (3) examine mechanisms that selected states' Medicaid programs use to interact and consult with Indian tribes, and (4) identify barriers to Medicare and Medicaid enrollment and efforts to help eligible American Indians and Alaska Natives apply for and enroll in these programs. …

Disaster Assistance: Federal Efforts to Assist Group Site Residents with Employment, Services for Families with Children, and Transportation (open access)

Disaster Assistance: Federal Efforts to Assist Group Site Residents with Employment, Services for Families with Children, and Transportation

A letter report issued by the Government Accountability Office with an abstract that begins "In August 2005, Hurricane Katrina caused more damage than any other single natural disaster in U.S. history, with Hurricane Rita adding to the devastation. The hurricanes hit some of the most distressed areas in the country. Louisiana and Mississippi had the highest poverty rates in the United States, according to the 2000 U.S. Census. Hurricane Katrina destroyed or made uninhabitable an estimated 300,000 homes, many of which had families with children. In response to this destruction, the Federal Emergency Management Agency (FEMA) provided many affected households with trailers for temporary housing in Louisiana and Mississippi. Those trailers not placed on homeowners' property were located in group sites. Although FEMA's guidance suggests that group sites should be located near existing supermarkets, public transportation, schools, and health care facilities, FEMA officials said the agency was not always able to locate temporary housing in these settings because of the level of destruction and, sometimes, opposition from communities. As of May 2008, several thousand households remained in group sites. Given the number of people who remained in group sites more than 2 years after Hurricane Katrina, GAO was asked to …

Next Generation Air Transportation System: Status of Systems Acquisition and the Transition to the Next Generation Air Transportation System (open access)

Next Generation Air Transportation System: Status of Systems Acquisition and the Transition to the Next Generation Air Transportation System

A letter report issued by the Government Accountability Office with an abstract that begins "The Joint Planning and Development Office (JPDO), an interagency organization within the Federal Aviation Administration (FAA), was created to plan and coordinate research and development for the next generation air transportation system (NextGen). Transitioning to NextGen will require FAA to continue to acquire new air traffic control (ATC) systems on schedule and on budget. GAO's concerns about the size, complexity, and cost of FAA's acquisition of ATC systems led GAO to designate this issue as high-risk in 1995. NextGen includes system acquisitions but is a significantly larger initiative involving multiple federal agencies, such as the National Aeronautics and Space Administration (NASA), which conducts aeronautics research and development for NextGen, and nonfederal aviation stakeholders, such as aviation equipment manufacturers, airports, and aircraft operators. GAO addressed (1) FAA's ATC systems acquisition activities, (2) key NextGen planning and transition issues, and (3) key challenges that FAA faces in implementing NextGen. GAO reviewed FAA's management processes and cost and schedule data for acquiring ATC systems, interviewed senior FAA, JPDO, and NASA officials, and 24 aviation stakeholders involved in NextGen. This report is also based on recent GAO products. The Department …

Augustine Band of Cahuilla Indians Energy Conservation and Options Analysis - Final Report (open access)

Augustine Band of Cahuilla Indians Energy Conservation and Options Analysis - Final Report

The Augustine Band of Cahuilla Indians was awarded a grant through the Department of Energy First Steps program in June of 2006. The primary purpose of the grant was to enable the Tribe to develop energy conservation policies and a strategy for alternative energy resource development. All of the work contemplated by the grant agreement has been completed and the Tribe has begun implementing the resource development strategy through the construction of a 1.0 MW grid-connected photovoltaic system designed to offset a portion of the energy demand generated by current and projected land uses on the Tribe’s Reservation. Implementation of proposed energy conservation policies will proceed more deliberately as the Tribe acquires economic development experience sufficient to evaluate more systematically the interrelationships between conservation and its economic development goals.

Characterization of Vadose Zone Sediments Below the T Tank Farm: Boreholes C4104, C4105, 299-W10-196, and RCRA Borehole 299-W11-39

This report was revised in September 2008 to remove acid-extractable sodium data from Tables 4.8, 4.28, and 4.52. The sodium data was removed due to potential contamination introduced during the acid extraction process. The rest of the text remains unchanged from the original report issued in September 2004. The overall goal of the Tank Farm Vadose Zone Project, led by CH2M HILL Hanford Group, Inc., is to define risks from past and future single-shell tank farm activities at Hanford. To meet this goal, CH2M HILL Hanford Group, Inc. tasked scientists from Pacific Northwest National Laboratory to perform detailed analyses on vadose zone sediments from within Waste Management Area (WMA) T-TX-TY. This report is the second of two reports written to present the results of these analyses. Specifically, this report contains all the geologic, geochemical, and selected physical characterization data collected on vadose zone sediment recovered from boreholes C4104 and C4105 in the T Tank Farm, and from borehole 299-W-11-39 installed northeast of the T Tank Farm. Finally, the measurements on sediments from borehole C4104 are compared with a nearby borehole drilled in 1993, 299- W10-196, through the tank T-106 leak plume.

Heterogeneous processes at the intersection of chemistry and biology: A computational approach (open access)

Heterogeneous processes at the intersection of chemistry and biology: A computational approach

Heterogeneous processes hold the key to understanding many problems in biology and atmospheric science. In particular, recent experiments have shown that heterogeneous chemistry at the surface of sea-salt aerosols plays a large role in important atmospheric processes with far reaching implications towards understanding of the fate and transport of aerosolized chemical weapons (i.e. organophosphates such as sarin and VX). Unfortunately, the precise mechanistic details of the simplest surface enhanced chemical reactions remain unknown. Understanding heterogeneous processes also has implications in the biological sciences. Traditionally, it is accepted that enzymes catalyze reactions by stabilizing the transition state, thereby lowering the free energy barrier. However, recent findings have shown that a multitude of phenomena likely contribute to the efficiency of enzymes, such as coupled protein motion, quantum mechanical tunneling, or strong electrostatic binding. The objective of this project was to develop and validate a single computational framework based on first principles simulations using tera-scale computational resources to answer fundamental scientific questions about heterogeneous chemical processes relevant to atmospheric chemistry and biological sciences.
