Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses GAO's efforts to coordinate with the accountability community--the Recovery Accountability and Transparency Board (the Board), the Inspectors General (IGs), and state and local government auditors--to help ensure effective and efficient oversight of American Recovery and Reinvestment Act (Recovery Act) funds. The Recovery Act assigns GAO a range of responsibilities including bimonthly reviews of the use of funds by selected states and localities. Because funding streams will flow from federal agencies to the states and localities, it is important for us to coordinate with the accountability community. Also, on March 19, 2009, GAO testified before this Subcommittee about the more than $21 billion in Recovery Act funds estimated to be spent for research and development (R&D) activities at four federal agencies. This statement discusses (1) GAO's efforts to fulfill its responsibilities under the Recovery Act; (2) GAO's coordination with others in the accountability community; (3) GAO's authorities to assist whistleblowers and elicit public concerns; and (4) updated information on the status of Recovery Act funds for R&D. It is based in part on GAO's first bimonthly Recovery Act report, Recovery Act: As Initial Implementation Unfolds in …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony highlights the results of our March 2009 report on undercover investigative tests, which confirmed the continued existence of significant fraud vulnerabilities in this process. We also provided a letter to you in April 2009, describing our recent work on passport fraud and summarizing actions the Department of State (State) has taken to address the prior weaknesses related to fraud vulnerabilities we identified. We have found that these vulnerabilities stem from people, process, and technology. For example, the lack of training and resources provided to people contributes to vulnerabilities in the detection of fraudulent applications and counterfeit documents. The limitations in the access to inter-agency information contribute to vulnerabilities related to processes. Finally, the lack of databases and information-sharing technologies contribute to vulnerabilities in the verification of passport applicants' records. A U.S. passport not only allows an individual to travel freely in and out of the United States, but also can be used to obtain further identification documents, prove U.S. citizenship, and set up bank accounts, among other things. Because passports issued under a false identity help enable individuals to conceal their movements and activities, there is …

Testimony issued by the Government Accountability Office with an abstract that begins "Information security is a critical consideration for any organization that depends on information systems and computer networks to carry out its mission or business. It is especially important for government agencies, where maintaining the public's trust is essential. The need for a vigilant approach to information security has been demonstrated by the pervasive and sustained computerbased (cyber) attacks against the United States and others that continue to pose a potentially devastating impact to systems and the operations and critical infrastructures that they support. GAO was asked to describe (1) cyber threats to federal information systems and cyberbased critical infrastructures and (2) control deficiencies that make these systems and infrastructures vulnerable to those threats. To do so, GAO relied on its previous reports and reviewed agency and inspectors general reports on information security."

This project focused on: 1) evaluating the performance of the DOE ARM SGP Raman lidar system in measuring profiles of water vapor and aerosols, and 2) the use of the Raman lidar measurements of aerosol and water vapor profiles for assessing the vertical distribution of aerosols and water vapor simulated by global transport models and examining diurnal variability of aerosols and water vapor. The highest aerosol extinction was generally observed close to the surface during the nighttime just prior to sunrise. The high values of aerosol extinction are most likely associated with increased scattering by hygroscopic aerosols, since the corresponding average relative humidity values were above 70%. After sunrise, relative humidity and aerosol extinction below 500 m decreased with the growth in the daytime convective boundary layer. The largest aerosol extinction for altitudes above 1 km occurred during the early afternoon most likely as a result of the increase in relative humidity. The water vapor mixing ratio profiles generally showed smaller variations with altitude between day and night. We also compared simultaneous measurements of relative humidity, aerosol extinction, and aerosol optical thickness derived from the ARM SGP Raman lidar and in situ instruments on board a small aircraft flown routinely …
