A letter report issued by the Government Accountability Office with an abstract that begins "The Afghan government, the United States, and other donors consider road reconstruction a top development priority for Afghanistan. Almost 20 percent of the U.S. Agency for International Development's (USAID) $5.9 billion in assistance to Afghanistan has been for roads. The Department of Defense (Defense) has committed about $560 million for roads, of which Commander's Emergency Response Program (CERP) funds account for over half. GAO examined (1) the status of road reconstruction and challenges affecting project implementation, (2) U.S. agencies' efforts to evaluate the impact of road projects, and (3) efforts to develop a sustainable road maintenance program. GAO reviewed U.S. and Afghan governments' planning, evaluation, and funding documents and interviewed relevant stakeholders in Afghanistan."

Testimony issued by the Government Accountability Office with an abstract that begins "A significantly greater proportion of African American children are in foster care than children of other races and ethnicities relative to their share of the general population. Given this situation, GAO was asked to analyze the (1) major factors influencing their proportion in foster care, (2) strategies states and localities have implemented that appear promising, and (3) ways in which federal policies may have influenced the proportion of African American children in foster care. This testimony is based on a GAO report issued in July 2007 (GAO-07-816), which included a nationwide survey; a review of research and policies; state site visits; analyses of child welfare data; and interviews with researchers, HHS officials, and other experts. It includes updates where possible."

The objective of this program was to explore a combination of advanced injection control and urea-selective catalytic reduction (SCR) to reduce the emissions of oxides of nitrogen (NOx) and particulate matter (PM) from a Tier 2 off-highway diesel engine to Tier 3 emission targets while maintaining fuel efficiency. The engine used in this investigation was a 2004 4.5L John Deere PowerTechTM; this engine was not equipped with exhaust gas recirculation (EGR). Under the original CRADA, the principal objective was to assess whether Tier 3 PM emission targets could be met solely by increasing the rail pressure. Although high rail pressure will lower the total PM emissions, it has a contrary effect to raise NOx emissions. To address this effect, a urea-SCR system was used to determine whether the enhanced NOx levels, associated with high rail pressure, could be reduced to Tier 3 levels. A key attraction for this approach is that it eliminates the need for a Diesel particulate filter (DPF) to remove PM emissions. The original CRADA effort was also performed using No.2 Diesel fuel having a maximum sulfur level of 500 ppm. After a few years, the CRADA scope was expanded to include exploration of advanced injection strategies …

Correspondence issued by the Government Accountability Office with an abstract that begins "The United States and many of its trading partners have enacted laws to remedy the unfair trade practices of other countries and foreign companies that cause injury to domestic industries. U.S. law authorizes the imposition of additional duties on importers to remedy these unfair trade practices. Specifically, antidumping (AD) duties are imposed on imports that are "dumped" in the United States (i.e., sales in the U.S. market at less than the market price in the item's home market) and countervailing (CV) duties are imposed on imports that are subsidized by foreign governments. Importers are responsible for paying all duties, taxes, and fees on products when they are brought into the United States (including AD/CV duties). Importers can be located either domestically or overseas. Since fiscal year 2001, U.S. Customs and Border Protection (CBP), which is responsible for collecting import duties, has been unable to collect hundreds of millions of dollars in AD/CV duties. In March 2008, we reported that over $600 million in AD/CV duties were uncollected. Our analysis revealed four key factors contributing to uncollected AD/CV duties: (1) the retrospective component of the U.S. AD/CV duty system, …

This report discusses the ongoing major USDA disaster programs designed to help crop producers recover from the financial effects of natural disasters — federal crop insurance, noninsured assistance program (NAP) payments, and emergency disaster loans.

The U.S. Department of Agriculture (USDA) offers several permanently authorized programs to help farmers recover financially from a natural disaster, including federal crop insurance, the noninsured assistance program (NAP), and emergency disaster loans. This report outlines the various agricultural disaster assistance appropriations included in the FY2007 Iraq war supplemental appropriations act; the Food, Conservation, and Energy Act of 2008; the 2008 farm bill; and the FY2008 Supplemental Appropriations Act.

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2008, the Federal Aviation Administration (FAA) plans to spend over $2 billion on information technology (IT) investments--many of which support FAA's air traffic control modernization. To more effectively manage such investments, in 2005 the Office of Management and Budget required agencies to use earned value management (EVM). EVM is a project management approach that, if implemented appropriately, provides objective reports of project status, produces early warning signs of impending schedule delays and cost overruns, and provides unbiased estimates of a program's total costs. Among other objectives, GAO was asked to assess FAA's policies for implementing EVM on its IT investments, evaluate whether the agency is adequately using these techniques to manage key IT acquisitions, and assess the agency's efforts to oversee EVM compliance. To do so, GAO compared agency policies with best practices, performed four case studies, and interviewed key FAA officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The airline industry is vital to the U.S. economy, generating operating revenues of nearly $172 billion in 2007, amounting to over 1 percent of the U.S. gross domestic product. It serves as an important engine for economic growth and a critical link in the nation's transportation infrastructure, carrying more than 700 million passengers in 2007. Airline deregulation in 1978, led, at least in part, to increasingly volatile airline profitability, resulting in periods of significant losses and bankruptcies. In response, some airlines have proposed or are considering merging with or acquiring another airline. GAO was asked to help prepare Congress for possible airline mergers or acquisitions. This report describes (1) the financial condition of the U.S. passenger airline industry, (2) whether the industry is becoming more or less competitive, (3) why airlines seek to merge with or acquire other airlines, and (4) the role of federal authorities in reviewing proposed airline mergers and acquisitions. To answer these objectives, we analyzed Department of Transportation (DOT) financial and operating data; interviewed agency officials, airline managers, and industry experts; and reviewed Horizontal Merger Guidelines and spoke with antitrust experts. DOT …

The alternative minimum tax (AMT) for individuals was originally enacted to ensure that all taxpayers, especially high-income taxpayers, pay at least a minimum amount of federal taxes. However, the AMT is not indexed for inflation, and this factor, combined with recent reductions in the regular income tax, has greatly expanded the potential impact of the AMT. This report explains legislation for the FY2009 budget compromise, which includes an offset AMT patch.

This study focuses on the remediation methods and technologies applicable for use at 200-PO-I Groundwater Operable Unit (OU) at the Hanford Site. The 200-PO-I Groundwater au requires groundwater remediation because of the existence of contaminants of potential concern (COPC). A screening was conducted on alternative technologies and methods of remediation to determine which show the most potential for remediation of groundwater contaminants. The possible technologies were screened to determine which would be suggested for further study and which were not applicable for groundwater remediation. COPCs determined by the Hanford Site groundwater monitoring were grouped into categories based on properties linking them by remediation methods applicable to each COPC group. The screening considered the following criteria. (1) Determine if the suggested method or technology can be used for the specific contaminants found in groundwater and if the technology can be applied at the 200-PO-I Groundwater au, based on physical characteristics such as geology and depth to groundwater. (2) Evaluate screened technologies based on testing and development stages, effectiveness, implementability, cost, and time. This report documents the results of an intern research project conducted by Mathew Dado for Central Plateau Remediation in the Soil and Groundwater Remediation Project. The study was conducted …

A dynamics simulation model is used to estimate limits of performance of the Positron-Electron Project (PEP-II). The simulation captures the dynamics and technical limitations of the Low Level Radio Frequency (LLRF) system, the high-power RF components and the low-order mode coupled bunch longitudinal beam dynamics. Simulation results showing the effect of non-linearities on the LLRF loops, and studies of the effectiveness of technical component upgrades are reported, as well as a comparison of these results with PEP-II measurements. These studies have led to the estimation of limits and determining factors in the maximum stored current that the Low Energy Ring/High Energy Ring (LER/HER) can achieve, based on system stability for different RF station configurations and upgrades. In particular, the feasibility of the PEP-II plans to achieve the final goal in luminosity, which required an increase of the beam currents to 4A for LER and 2.2A for HER, is studied. These currents are challenging in part because they would push the longitudinal low-order beam mode stability to the limit, and the klystron forward power past a level of satisfactory margin. An acceptable margin is defined in this paper, which in turn determines the corresponding klystron forward power limitation.

Mission Research develops analyst tools and automated quality control software in order to assist the Atmospheric Radiation Measurement (ARM) Data Quality Office with their data inspection tasks. We have developed web-based data analysis and visualization tools such as the interactive plotting program NCVweb, various diagnostic plot browsers, and a datastream processing status application. These tools allow even novice ARM researchers to be productive with ARM data with only minimal effort. We also contribute to the ARM Data Quality Office by analyzing ARM data streams, developing new quality control metrics, new diagnostic plots, and integrating this information into DQ HandS - the Data Quality Health and Status web-based explorer. We have developed several ways to detect outliers in ARM data streams and have written software to run in an automated fashion to flag these outliers. We have also embarked on a system to comprehensively generate long time-series plots, frequency distributions, and other relevant statistics for scientific and engineering data in most high-level, publicly available ARM data streams. Furthermore, frequency distributions categorized by month or by season are made available to help define valid data ranges specific to those time domains. These statistics can be used to set limits that when checked, …

Using spectroscopic information for x ray magnetometry and magnetic microscopy requires detailed theoretical understanding of spectral shape and magnitude of dichroism signals. We have shown unambiguously that--contrary to common belief--spectral shape and magnitude of x ray magnetic linear dichroism (XMLD) are not only determined by the relative orientation of magnetic moments and x ray polarization, but also their orientations relative to the crystallographic axes must be taken into account for accurate interpretation of XMLD data.
