Many Members of Congress charge that China's policy of accumulating foreign reserves (especially U.S. dollars) to influence the value of its currency constitutes a form of currency manipulation intended to make its exports cheaper and imports into China more expensive than they would be under free market conditions. Although China made modest reforms to its currency policy in 2005, Members contend the forms have not gone far enough and have warned of potential legislative action. This report summarizes the main findings CRS Report RL32165, China's Currency: Economic Issues and Options for U.S. Trade Policy.

Varying media estimates of military forces in Iraq have raised concerns about the actual number of troops deployed in Operation Iraqi Freedom (OIF). Last year, a major announcement on a surge in troop deployments to Iraq by President Bush included a planned gradual increase of more than 20,000 U.S. troops on the ground in Baghdad and Anbar province over several months. Since the "new strategy for Iraq" speech by the President in January 2007, troop deployments gradually increased during the months of February through October 2007 but decreased beginning in November 2007. This report provides solely Department of Defense (DOD) statistical information on U.S. forces serving in Iraq. It also provides brief official information on the military units schedule for the next rotation of duty into Iraq.

Concerns about potential disruptions in U.S. trade flows due to a global health or security crisis are not new. The possibility of an avian flu pandemic with consequences for global trade is a concern that has received attention recently, although some experts believe there is little cause for alarm. This report considers possible trade disruptions, including possible impacts on trade between the United States and countries and regions that have reported avian influenza infections.

The International Monetary Fund (IMF) and World Trade Organization (WTO) approach the issue of "currency manipulation" differently. The IMF Articles of Agreement prohibit countries from manipulating their currency for the purpose of gaining unfair trade advantage, but the IMF cannot force a country to change its exchange rate policies. The WTO has rules against subsidies, but these are very narrow and specific and do not seem to encompass currency manipulation. Several options might be considered for addressing this matter in the future, if policymakers deem this a wise course of action.

China is a major source of U.S. imports of consumer products (such as toys) and an increasingly important supplier of various food products. Reports of unsafe seafood, pet food, toys, tires, and other products imported from China over the past year or so have raised concern in the United States over the health, safety, and quality of imported Chinese products. This report provides an overview of this issue and implications for U.S.-China trade relations.

This report discusses rising food prices that are having impacts across the world, but especially among poor people in the low-income developing countries. The report addresses several issues, such as: Why Are Food Prices Increasing? How Countries Have Responded? Food Aid Funding Shortfalls, and the U.S. Response to Food Aid Funding Shortfalls.

This report summarizes China's economic issues and its currency manipulation, intended to make its exports cheaper and imports into China more expensive than they would be under free market conditions.

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has relied on service acquisitions to meet its expansive mission. In fiscal year 2006, DHS spent $12.7 billion to procure services. To improve service acquisition outcomes, federal procurement policy establishes a preference for a performance-based approach, which focuses on developing measurable outcomes rather than prescribing how contractors should perform services. This testimony focuses on how contract outcomes are influenced by how well DHS components have defined and developed contract requirements and performance standards, as well as the need for improved assessment and oversight to ensure better acquisition outcomes. GAO's statement is based on its report being released today, which reviewed judgmentally selected contracts for eight major investments at three DHS components--the Coast Guard, Customs and Border Protection (CBP), and the Transportation Security Administration (TSA)-- totaling $1.53 billion in fiscal years 2005 and 2006; prior GAO and DHS Inspector General reviews; management documents and plans; and related data, including 138 additional contracts, primarily for basic services from the Coast Guard, CBP, TSA, and Immigration and Customs Enforcement."

Testimony issued by the Government Accountability Office with an abstract that begins "To address the challenges that the nation faces, it will be important for federal agencies to change their cultures and create the institutional capacity to become high-performing organizations. This includes recruiting and retaining a federal workforce able to create, sustain, and thrive in organizations that are flatter, results-oriented, and externally focused. In 2001, GAO identified strategic human capital management as a governmentwide high-risk area because federal agencies lacked a strategic approach to human capital management that integrated human capital efforts with their missions and program goals. Although progress has been made since that time, strategic human capital management still remains a high-risk area. This testimony, based on a large body of completed work issued from January 2001 through April 2008, focuses on (1) challenges that federal agencies have faced in recruiting and hiring talented employees, (2) progress in addressing these challenges, and (3) additional actions that are needed to strengthen recruiting and hiring efforts. In its prior reports, GAO has made a range of recommendations to the Office of Personnel Management (OPM)--the government's personnel agency--and to agencies in such areas as hiring, workforce planning, and diversity management; a …

Testimony issued by the Government Accountability Office with an abstract that begins "Physical infrastructure is critical to the nation's economy and affects the daily life of virtually all Americans--from facilitating the movement of goods and people within and beyond U.S. borders to providing clean drinking water. However, this infrastructure--including aviation, highway, transit, rail, water, and dam infrastructure--is under strain. Estimates to repair, replace, or upgrade aging infrastructure as well as expand capacity to meet increased demand top hundreds of billions of dollars. Calls for increased investment in infrastructure come at a time when traditional funding for infrastructure projects is increasingly strained, and the federal government's fiscal outlook is worse than many may understand. This testimony discusses (1) challenges associated with the nation's surface transportation, aviation, water, and dam infrastructure, and the principles GAO has identified to help guide efforts to address these challenges and (2) existing and proposed options to fund investments in the nation's infrastructure. This statement is primarily based on a body of work GAO has completed for the Congress over the last several years. To supplement this existing work, GAO also interviewed Department of Transportation officials to obtain up-to-date information on the status of the Highway Trust …

Testimony issued by the Government Accountability Office with an abstract that begins "Millions of people rely on the services of Social Security Administration (SSA) field offices. In fiscal year 2007, SSA's approximately 1,300 field offices provided service to about 42 million customers. People use these offices to apply for Social Security cards, apply for retirement and disability benefits, establish direct deposit, and a host of other services. While customers may conduct their business using SSA's online, telephone, or other service options, many prefer the personalized contact provided in field offices. Over the last several years, staffing reductions have challenged field offices' ability to manage work, while continuing to deliver quality customer service. To assess how field offices are managing these challenges, GAO was asked to determine (1) the effect that reduced staffing levels may be having on field office operations and (2) the challenges that SSA faces in meeting future service delivery needs. This statement is drawn from GAO's ongoing study on field offices for the committee, which is expected to be issued later this year. To conduct this work, GAO interviewed SSA officials in headquarters, and other components, and analyzed various data on SSA's workloads and other data. In …

Testimony issued by the Government Accountability Office with an abstract that begins "The Food and Drug Administration (FDA) is responsible for overseeing direct-to-consumer (DTC) advertising of prescription drugs, which includes a range of media, such as television, magazines, and the Internet. If FDA identifies a violation of laws or regulations in a DTC advertising material, the agency may issue a regulatory letter asking the drug company to take specific actions. In 2002, GAO reported on delays in FDA's issuance of regulatory letters. GAO was asked to discuss trends in FDA's oversight of DTC advertising and the actions FDA has taken when it identifies violations. This statement is based on GAO's 2006 report, Prescription Drugs: Improvements Needed in FDA's Oversight of Direct-to-Consumer Advertising, GAO-07-54 (November 16, 2006). In this statement, GAO discusses the (1) DTC advertising materials FDA reviews, (2) FDA's process for issuing regulatory letters citing DTC advertising materials and the number of letters issued, and (3) the effectiveness of FDA's regulatory letters at limiting the dissemination of false or misleading DTC advertising. For its 2006 report, GAO examined FDA data on the advertising materials the agency received and reviewed the regulatory letters it issued citing prescription drug promotion from …

A letter report issued by the Government Accountability Office with an abstract that begins "Interagency contracting--using another agency's contracts or contracting services--can provide agencies with opportunities to streamline the procurement process and achieve savings. However, GAO designated the management of interagency contracting a high-risk area in 2005 due, in part, to a lack of reliable data on its use and of clarity regarding contract management responsibilities. In 2002, the Department of State (State) issued the State First policy, requiring domestic bureaus to obtain approval from State acquisition officials before paying other agencies for contract support services. Under the Comptroller General's authority to conduct evaluations on his own initiative, GAO evaluated State's 1) insight into its use of interagency contracts, 2) policies on deciding when to use assisted interagency contracts, and 3) ability to ensure oversight. GAO's work included reviewing regulations, analyzing interagency contracting data, and conducting 10 case studies of direct and assisted interagency contracts that represented a range of State bureaus and servicing agencies."

Cumulative reaction probability (CRP) calculations provide a viable computational approach to estimate reaction rate coefficients. However, in order to give meaningful results these calculations should be done in many dimensions (ten to fifteen). This makes CRP codes memory intensive. For this reason, these codes use iterative methods to solve the linear systems, where a good fraction of the execution time is spent on matrix-vector multiplication. In this paper, we discuss the tensor product form of applying the system operator on a vector. This approach shows much better performance and provides huge savings in memory as compared to the explicit sparse representation of the system matrix.

The temporal dispersion of an optical spectrometer has been characterized for a variety of conditions related to optical diagnostics to be fielded at the National Ignition Facility (e.g., Full-Aperture Backscatter Station, Thomson Scattering). Significant time smear is introduced into these systems by the path length difference through the spectrometer. The temporal resolution can be calculated to depend only on the order of the grating, wavelength, and the number of grooves illuminated. To enhance the temporal dispersion, the spectral gratings can be masked limiting the number of grooves illuminated. Experiments have been conducted to verify these calculations. The size and shape of masks are investigated and correlated to the exact shape of the temporal instrument function, which is required when interpreting temporally resolved data. The experiments used a 300fs laser pulse and a picosecond optical streak camera to determine the temporal dispersion. This was done for multiple spectral orders, gratings, and optical masks.

This project was a collaboration between The Energy & Environmental Research Center (EERC) and Chugachmiut – A Tribal organization Serving the Chugach Native People of Alaska and funded by the U.S. Department of Energy (DOE) Tribal Energy Program. It was conducted to determine the economic and technical feasibility for implementing a biomass energy system to service the Chugachmiut community of Port Graham, Alaska. The Port Graham tribe has been investigating opportunities to reduce energy costs and reliance on energy imports and support subsistence. The dramatic rise in the prices of petroleum fuels have been a hardship to the village of Port Graham, located on the Kenai Peninsula of Alaska. The Port Graham Village Council views the forest timber surrounding the village and the established salmon industry as potential resources for providing biomass energy power to the facilities in their community. Benefits of implementing a biomass fuel include reduced energy costs, energy independence, economic development, and environmental improvement. Fish oil–diesel blended fuel and indoor wood boilers are the most economical and technically viable options for biomass energy in the village of Port Graham. Sufficient regional biomass resources allow up to 50% in annual heating savings to the user, displacing up to …

The next generation of large scale fusion devices--ITER/LMJ/NIF--will require diagnostic components to operate in environments far more severe than those encountered in present facilities. This harsh environment will be induced by fluxes of neutrons, gamma rays, energetic ions, electromagnetic radiation, and in some cases debris and shrapnel, at levels several orders of magnitude higher than those experienced in today's devices. For several years the question of possible synergy between inertial and the magnetic confinement research has been pursued by members of the respective communities. A first joint workshop specifically devoted to the identification and promotion of these synergies was organized in France, at Aix-en-Provence from June 27th to 29th, 2007. The workshop was attended by about 50 invited specialists. The participants identified a number of subject areas where common overlapping interests could benefit from additional interactions and meetings: windows, optical fibers, mirrors, cables, electronic components and 14 MeV neutron sources. In this paper we summarize the findings of these working groups. We put the discussion into context by including a brief description of the environments and the physical effects that have to be handled.
