Correspondence issued by the Government Accountability Office with an abstract that begins "Health care providers and members of Congress have raised concerns that consolidation in the private health insurance industry may be resulting in less competitive markets and contributing to rising health insurance rates paid by consumers and employers. However, measuring the extent of changes in market competition over time or the effects of changes is challenging. In particular, reliable, longitudinal data to measure concentration, that is, the number of competitors and their relative market share, are only available on health maintenance organizations (HMO) but not on preferred provider organizations (PPO) or other insurance products that may comprise the market. Further, data on health insurers are not available at all geographic levels. Despite these challenges, researchers have used the data available to study competition in health insurance markets, typically using one of two measures of competition: (1) HMO market concentration or (2) the number of HMOs in a market. Researchers acknowledge that market concentration and the number of competitors are not perfect measures of competition in private health insurance markets and that there are limits to the conclusions to be drawn from studies that rely on the available data. This …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses our work on the Troubled Asset Relief Program (TARP), under which the Department of the Treasury (Treasury) has the authority to purchase and insure up to $700 billion in troubled assets held by financial institutions through its Office of Financial Stability (OFS). As Congress may know, Treasury was granted this authority in response to the financial crisis that has threatened the stability of the U.S. banking system and the solvency of numerous financial institutions. The Emergency Economic Stabilization Act (the act) that authorized TARP on October 3, 2008, requires GAO to report at least every 60 days on the findings resulting from our oversight of the actions taken under the program. We are also responsible for auditing TARP's annual financial statements and for producing special reports on any issues that emerge from our oversight. To carry out these oversight responsibilities, we have assembled interdisciplinary teams with a wide range of technical skills, including financial market and public policy analysts, accountants, lawyers, and economists who represent combined resources from across GAO. This testimon is based primarily on our March 31, 2009 report that we are issuing …

Testimony issued by the Government Accountability Office with an abstract that begins "The American Recovery and Reinvestment Act of 2009 (Recovery Act) included more than $48 billion for the Department of Transportation's (DOT) investment in transportation infrastructure, including highways, rail, and transit. This testimony--based on GAO report GAO-09-829, issued on July 8, 2009 and updated with more recent data, in response to a mandate under the Recovery Act--addresses (1) the uses of Recovery Act transportation funding including the types of projects states have funded, (2) the steps states have taken to meet the act's requirements, and (3) GAO's other work on transportation funding under the Recovery Act. In GAO-09-829, GAO examined the use of Recovery Act funds by 16 states and the District of Columbia (District), representing about 65 percent of the U.S. population and two-thirds of the federal assistance available through the act. GAO also obtained data from DOT on obligations and reimbursements for the Recovery Act's highway infrastructure funds."

Correspondence issued by the Government Accountability Office with an abstract that begins "This report presents the results of GAO's review of the expenses of the Office of Special Counsel-Patrick J. Fitzgerald (OSC-Fitzgerald) for the 6 months ended September 30, 2008. The expenses we reviewed were those made by the Department of Justice (DOJ) between April 1, 2008, and September 30, 2008, from the permanent, indefinite appropriation (fund) for OSC-Fitzgerald. To determine if there were additional payments made subsequent to the 6-month period covered by our review, we also reviewed expenses paid out of the fund between October 1, 2008, and February 28, 2009. DOJ determined that the appropriation established by Public Law 100-2021 to fund expenses by independent counsels pursuant to the independent counsel law or other law is available to fund the expenses of U.S. Attorney Patrick J. Fitzgerald, who was appointed as a special counsel within the Department of Justice by the then-Acting Attorney General. Under this law, we are required to perform semiannual financial reviews of expenses from the fund, and, we report our findings to the House and Senate Appropriations Committees. To satisfy this requirement, we review each expense processed by DOJ to determine whether it …

One of the most promising methods of capturing CO{sub 2} emitted by coal-fired power plants for subsequent sequestration is chemical looping combustion (CLC). A powdered metal oxide such as NiO transfers oxygen directly to a fuel in a fuel reactor at high temperatures with no air present. Heat, water, and CO{sub 2} are released, and after H{sub 2}O condensation the CO{sub 2} (undiluted by N{sub 2}) is ready for sequestration, whereas the nickel metal is ready for reoxidation in the air reactor. In principle, these processes can be repeated endlessly with the original nickel metal/nickel oxide participating in a loop that admits fuel and rejects ash, heat, and water. Our project accumulated kinetic rate data at high temperatures and elevated pressures for the metal oxide reduction step and for the metal reoxidation step. These data will be used in computational modeling of CLC on the laboratory scale and presumably later on the plant scale. The oxygen carrier on which the research at Utah is focused is CuO/Cu{sub 2}O rather than nickel oxide because the copper system lends itself to use with solid fuels in an alternative to CLC called 'chemical looping with oxygen uncoupling' (CLOU).

The Energy & Environmental Research Center (EERC) has developed an interactive, Web-based decision support system (DSS{copyright} 2007 EERC Foundation) to provide power generation utilities with an assessment tool to address water supply issues when planning new or modifying existing generation facilities. The Web-based DSS integrates water and wastewater treatment technology and water law information with a geographic information system-based interactive map that links to state and federal water quality and quantity databases for North Dakota, South Dakota, Minnesota, Wyoming, Montana, Nebraska, Wisconsin, and Iowa.
