A letter report issued by the Government Accountability Office with an abstract that begins "Unemployment Insurance (UI), established in 1935, is a complex system of 53 state programs that in fiscal year 2004 provided $41.3 billion in temporary cash benefits to 8.8 million eligible workers who had become unemployed through no fault of their own. Given the size of the UI program, its importance in helping workers meet their needs when they are unemployed, and the little information available on what factors lead eligible workers to receive benefits over time, GAO was asked to determine (1) the extent to which an individual worker's characteristics, including past UI benefit receipt, are associated with the likelihood of UI benefit receipt or unemployment duration, and (2) whether an unemployed worker's industry is associated with the likelihood of UI benefit receipt and unemployment duration. Using data from a nationally representative sample of workers born between 1957 and 1964 and spanning the years 1979 through 2002, and information on state UI eligibility rules, GAO used multivariate statistical techniques to identify the key factors associated with UI benefit receipt and unemployment duration. In its comments, the Department of Labor stated that while there are certain qualifications …

A letter report issued by the Government Accountability Office with an abstract that begins "U.S. trade preference programs promote economic development in poorer nations by providing export opportunities. The Generalized System of Preferences, Caribbean Basin Initiative, Andean Trade Preference Act, and African Growth and Opportunity Act unilaterally reduce U.S. tariffs for many products from over 130 countries. However, three of these programs expire partially or in full this year, and Congress is exploring options as it considers renewal. GAO was asked to review the programs' effects on the United States and on foreign beneficiaries' exports and development, identify policy trade-offs concerning these programs, and evaluate the overall U.S. approach to preference programs. To address these objectives, we analyzed trade data, reviewed trade literature and program documents, interviewed U.S. officials, and did fieldwork in six countries."

A letter report issued by the Government Accountability Office with an abstract that begins "In the interest of national security and personal privacy and for other reasons, federal agencies place dissemination restrictions on information that is unclassified yet still sensitive. The Department of Energy (DOE) and the Department of Defense (DOD) have both issued policy guidance on how and when to protect sensitive information. DOE marks documents with this information as Official Use Only (OUO) while DOD uses the designation For Official Use Only (FOUO). GAO was asked to (1) identify and assess the policies, procedures, and criteria DOE and DOD employ to manage OUO and FOUO information and (2) determine the extent to which DOE's and DOD's training and oversight programs assure that information is identified, marked, and protected according to established criteria."

A letter report issued by the Government Accountability Office with an abstract that begins "As requested, we provided for audits of the financial statements of the U.S. Senate Restaurants Revolving Fund (the Fund) for the fiscal years ended September 30, 2007, and 2006, by contracting with the independent public accounting firm of Clifton Gunderson LLP. The contract required that the audit be conducted in accordance with U.S. generally accepted government auditing standards and the joint GAO/President's Council on Integrity and Efficiency (PCIE) Financial Audit Manual."

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) Business Systems Modernization (BSM) program is a multibillion-dollar, high-risk, highly complex effort that involves the development and delivery of a number of modernized systems that are intended to replace the agency's aging business and tax processing systems. As required by law, IRS submitted its fiscal year 2008 expenditure plan in August 2007 to congressional appropriations committees, requesting $235.8 million from the BSM account. GAO's objectives in reviewing the plan were to (1) determine whether it satisfied the conditions specified in the law, (2) determine IRS's progress in implementing prior expenditure plan review recommendations, and (3) provide additional observations about the plan and the BSM program. To accomplish the objectives, GAO analyzed the plan, reviewed related documentation, and interviewed IRS officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Maritime Administration (MARAD) has more than 100 obsolete and deteriorating ships awaiting disposal that pose potentially costly environmental threats to the waterways near where they are stored. Congress, in 2000, mandated that MARAD dispose of them by September 30, 2006. While MARAD has various disposal options available, each option is complicated by legal, financial, and regulatory factors. In this report, GAO assesses (1) whether MARAD will meet the September 2006 disposal deadline for these ships and, if not, why not; (2) the extent that MARAD has used alternative disposal methods other than scrapping, and barriers to using other methods; (3) the appropriateness of MARAD's methods for procuring ship disposal services; and (4) the impact of foreign competition and other factors on reducing disposal costs."

A letter report issued by the Government Accountability Office with an abstract that begins "The Army's Future Combat System (FCS) requires a software-based advanced information network to meld people, sensors, and weapons into a cohesive fighting force. As software controls 95 percent of FCS's functionality, it determines the success or failure of the program. The Army contracted with the Boeing Company as a lead systems integrator (LSI) to define, develop and integrate FCS, including software development. GAO must by law report annually on FCS. This is one of two reports to meet this requirement. It addresses risks facing the development of network and software, the practices being used to manage software, and the timing of key network demonstrations. In conducting our work, GAO has contacted numerous DOD, Army, and contractor offices; reviewed technical documents on software and network development and plans; attended meetings; and spoken to Army and other officials on various aspects of FCS network and software development. GAO also performed detailed work at five FCS software developers."

A letter report issued by the Government Accountability Office with an abstract that begins "The Future Combat System (FCS) program--which comprises 14 integrated weapon systems and an advanced information network--is the centerpiece of the Army's effort to transition to a lighter, more agile, and more capable combat force. The substantial technical challenges, the Army's acquisition strategy, and the cost of the program are among the reasons why the program is recognized as needing special oversight and review. Section 211 of the National Defense Authorization Act for Fiscal Year 2006 requires GAO to report annually on the FCS program. This report includes an examination of (1) how the definition, development, and demonstration of FCS capabilities are proceeding, particularly in light of the go/no-go decision scheduled for 2009; (2) the Army's plans for making production commitments for FCS and any risks related to the completion of development; and (3) the estimated costs for developing and producing FCS."

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) contains EPA's scientific position on the potential human health effects of exposure to more than 540 chemicals. IRIS is a critical component of EPA's capacity to support scientifically sound environmental decisions, policies, and regulations. GAO was asked to examine (1) the outcome of steps EPA has taken to ensure that IRIS contains current, credible chemical risk information, to address the backlog of ongoing assessments, and to respond to new requirements from the Office of Management and Budget (OMB); and (2) the potential effects of planned changes to the IRIS assessment process on EPA's ability to ensure that IRIS provides current, credible risk information. To do this work, GAO reviewed and analyzed EPA data and interviewed officials at relevant agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "Many defense contractor employees work side-by-side with federal employees in Department of Defense (DOD) facilities performing substantially the same tasks affecting billions in DOD spending. Given concerns with protecting the integrity of DOD operations, GAO was asked to assess (1) how many contractor employees work in DOD offices and what type of mission-critical contracted services they perform, (2) what safeguards there are to prevent personal conflicts of interest for contractor employees when performing DOD's tasks, and (3) whether government and defense contractor officials believe additional safeguards are necessary. GAO reviewed conflicts of interest laws and policies and interviewed ethics officials and senior leaders regarding applicability to DOD federal and contractor employees. GAO judgmentally selected and interviewed officials at 21 DOD offices with large contractor workforces, and 23 of their contractors."

A letter report issued by the Government Accountability Office with an abstract that begins "A fundamental principle of military readiness is that the military must train as it intends to fight, and military training ranges allow the Department of Defense (DOD) to accomplish this goal. According to DOD officials, heightened focus on the application of environmental statutes has affected the use of its training areas. Since 2003, DOD has obtained exemptions from three environmental laws and has sought exemptions from three others. This report discusses the impact, if any, of (1) environmental laws on DOD's training activities and military readiness, (2) DOD's use of statutory exemptions from environmental laws on training activities, (3) DOD's use of statutory exemptions on the environment, and (4) the extent to which DOD has demonstrated the need for additional exemptions. To address these objectives, GAO visited 17 training locations; analyzed environmental impact and readiness reports; and met with officials at service headquarters, the Office of the Secretary of Defense, federal regulatory agencies, and nongovernmental environmental groups."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the efforts of states and the Food and Nutrition Service (FNS) to reduce Food Stamp trafficking, focusing on the: (1) extent to which the states with statewide electronic benefit transfer (EBT) systems are identifying and disqualifying recipients who engage in trafficking; and (2) actions FNS has taken to encourage the states to identify and disqualify recipients engaged in trafficking."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on differences in the Army's and Air Force's disbursing and accounting records, focusing on: (1) if, and to what extent, contract payment transactions recorded in the Army and the Air Force official accounting records differed from mechanization of contract administration services (MOCAS) disbursing system records; (2) the types of differences between the disbursing and accounting systems and, to the extent possible, the causes for the differences; and (3) the potential effect any identified deficiencies may have on the Department of Defense's (DOD) planned contract payment system improvements."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on recent trends in retention rates among officers and enlisted personnel in the four armed services, focusing on: (1) how much information the Department of Defense (DOD) has on retention trends across the services; and (2) analyzing changes in retention rates in the aggregate and by career stage and occupation from 1988 through 1998."

A letter report issued by the Government Accountability Office with an abstract that begins "Federal and Montana state agencies have long been entangled in controversy over bison leaving Yellowstone National Park. Some of these bison, as well as elk and other wildlife, have a contagious disease called brucellosis, which can cause pregnant animals to abort. Montana livestock owners and government officials fear that if bison are allowed to leave the park, the disease could spread to cattle, potentially threatening the economic health of the state's livestock industry. To help manage this issue, three federal and two state agencies have been implementing a bison management plan that they agreed to in 2000. This report discusses (1) the progress made in implementing the bison management plan and (2) the plan's soundness and the effectiveness of the agencies' implementation of it for managing bison-related issues in and near Yellowstone National Park. GAO reviewed documentation and research on bison and brucellosis and interviewed federal and state officials and key stakeholders."

Critical assemblies are exquisitely sensitive to details of the microscopic nuclear reactions that govern neutron multiplication. For this reason experimental studies of critical assemblies represent a cornerstone in the process of validating nuclear data. Several different characteristics of a critical system can be measured. The most commonly considered is the so-called effective k eigenvalue, k{sub eff}. Another well-measured property of these systems is {alpha}{sub 0}, the inverse e-folding time of the neutron population in the absence of {beta}-delayed neutrons. Through Monte Carlo calculations and appear to perturbation theory they show that for fast critical systems {alpha}{sub 0} and k{sub eff} can be viewed as lying on a single straight line for any reasonable assumptions about the underlying nuclear data. This means that the two quantities provide the same constraint on nuclear data. In principle, {alpha}{sub 0} could be associated with a very small uncertainty, and this would make the measurements for neutron multiplication rates more useful than k{sub eff} for constraining nuclear data. In practice, though, uncertainties in k{sub eff} and {alpha}{sub 0} are dominated by uncertainties in the representation of the critical system, and not by pure measurement errors for these quantities. This, together with the linear relation between …

We developed a new fluid property module for TOUGH2, called EOSN, to simulate transport of noble gases in the subsurface. Currently, users may select any of five different noble gases as well as CO2, two at a time. For the three gas components (air and two user-specified noble gases) in EOSN, the Henry's coefficients and the diffusivities in the gas phase are no longer assumed constants, but are temperature dependent. We used the Crovetto et al. (1982) model to estimate Henry's coefficients, and the Reid et al. (1987) correlations to calculate gas phase diffusivities. The new module requires users to provide names of the selected noble gases, which properties are provided internally. There are options for users to specify any (non-zero) molecular weights and half-lives for the gas components. We provide two examples to show applications of TOUGH2IEOSN. While temperature effects are relatively insignificant for one example problem where advection is dominant, they cause almost an order of magnitude difference for the other case where diffusion becomes a dominant process and temperature variations are relatively large. It appears that thermodynamic effects on gas diffusivities and Henry's coefficients can be important for low-permeability porous media and zones with large temperature variations.

The program established a collaborative process with domestic industries for the purpose of sharing Navy-developed technology. Private sector businesses were educated so as to increase their awareness of the vast amount of technologies that are available, with an initial focus on technology applications that are related to the Hydrogen, Fuel Cells and Infrastructure Technologies (Hydrogen) Program of the U.S. Department of Energy. Specifically, the project worked to increase industry awareness of the vast technology resources available to them that have been developed with taxpayer funding. NAVSEA-Carderock and the Houston Advanced Research Center teamed with Nicholls State University to catalog NAVSEA-Carderock unclassified technologies, rated the level of readiness of the technologies and established a web based catalog of the technologies. In particular, the catalog contains technology descriptions, including testing summaries and overviews of related presentations.
