Testimony issued by the Government Accountability Office with an abstract that begins "We found that the Army could not readily identify a complete population of Army payroll accounts for fiscal year 2010, given existing procedures and systems. The Army and DFAS-IN did not have an effective, repeatable process for identifying the population of active duty payroll accounts. In addition, the Defense Manpower Data Center (DMDC), DOD’s central source for personnel information, did not have an effective process for comparing military pay account files to military personnel files to identify a valid population of military payroll transactions. For example, it took 3 months and repeated attempts before DFAS-IN could provide a population of service members who received active duty Army military pay in fiscal year 2010. Similarly, it took DMDC over 2 months to compare the total number of fiscal year 2010 active duty payroll accounts to its database of personnel files. "Standards for Internal Control in the Federal Government" requires all transactions and other significant events to be clearly documented and the documentation readily available for examination. DOD’s "Financial Improvement and Audit Readiness (FIAR) Guidance" sets out key tasks essential to achieving audit readiness, including defining and identifying the population …

Testimony issued by the Government Accountability Office with an abstract that begins "Over time, federal surveys have consistently found that Department of Homeland Security (DHS) employees are less satisfied with their jobs than the government-wide average. In the 2004 Office of Personnel Management’s federal employee survey—a tool that measures employees’ perceptions of whether and to what extent conditions characterizing successful organizations are present in their agency—56 percent of DHS employees responded that they were satisfied with their jobs, compared to 68 percent government-wide. In subsequent years, the disparity continued—ranging from a difference of 8 percentage points in 2006 to a 4 percentage point difference in 2008, 2010, and 2011. In 2011, DHS’s percentage of positive responses was lower than the averages for the rest of the federal government. For example, slightly less than half of the DHS employees surveyed reported positive responses to the statement “My talents are used well in the workplace,” nearly 12 percentage points less than the rest of the federal government average. In two areas, DHS’s percentage of positive responses was nearly the same or higher than the rest of the federal government average. For example, DHS’s percentage of positive responses to the statement “Considering everything, …

Funded by the DOE grant (i) we continued to study and analyze the atomistic detail of the electron transfer (ET) across the chromophore-TiO2 interface in Gratzel cell systems for solar hydrogen production. (ii) We extensively investigated the nature of photoexcited states and excited state dynamics in semiconductor quantum dots (QD) designed for photovoltaic applications. (iii) We continued a newly initiated research direction focusing on excited state properties and electron-phonon interactions in nanoscale carbon materials. Over the past year, the results of the DOE funded research were summarized in 3 review articles. 12 original manuscripts were written. The research results were reported in 28 invited talks at conferences and university seminars. 20 invitations were accepted for talks in the near future. 2 symposia at national and international meetings have being organized this year on topics closely related to the DOE funded project, and 2 more symposia have been planned for the near future. We summarized the insights into photoinduced dynamics of semiconductor QDs, obtained from our time-domain ab initio studies. QDs exhibit both molecular and bulk properties. Unlike either bulk or molecular materials, QD properties can be modified continuously by changing QD shape and size. However, the chemical and physical properties …

Theoretical calculations were carried out to search for lightweight alloys that can be used to reversibly store hydrogen in mobile applications, such as automobiles. Our primary focus was on magnesium based alloys. While MgH{sub 2} is in many respects a promising hydrogen storage material, there are two serious problems which need to be solved in order to make it useful: (i) the binding energy of the hydrogen atoms in the hydride is too large, causing the release temperature to be too high, and (ii) the diffusion of hydrogen through the hydride is so slow that loading of hydrogen into the metal takes much too long. In the first year of the project, we found that the addition of ca. 15% of aluminum decreases the binding energy to the hydrogen to the target value of 0.25 eV which corresponds to release of 1 bar hydrogen gas at 100 degrees C. Also, the addition of ca. 15% of transition metal atoms, such as Ti or V, reduces the formation energy of interstitial H-atoms making the diffusion of H-atoms through the hydride more than ten orders of magnitude faster at room temperature. In the second year of the project, several calculations of alloys …
