This report focuses on Syria’s internal politics and the impact of hostilities in Iraq on Syria’s stability and U.S.-Syrian relations. It outlines the development of the the regime currently headed by President Bashar al-Asad and its support base; describes potential challenges to the regime; examines the effect of the Iraq war on Syrian domestic politics and U.S.-Syrian relations; and reviews U.S. policy options toward Syria. It will be updated when significant changes take place and affect these relationships. For more information on Syrian foreign policy issues, see CRS Issue Brief IB92075, Syria: U.S. Relations and Bilateral Issues, by Alfred B. Prados.

This issue brief discusses the increasing attention being paid to alternative fuels and advanced technology vehicles, the proponents of which point to their potential to improve urban air quality, decrease dependence on foreign oil, and reduce greenhouse gas emissions. The brief also discusses the major barriers currently preventing widespread use of such technologies, and discusses these technologies in the particular contexts of the 2005 Gulf Coast hurricanes and the Energy Policy Act of 2005.

A letter report issued by the Government Accountability Office with an abstract that begins "With a number of challenges facing the nation--including a long-term fiscal imbalance--agencies need to maximize their performance and leverage available resources and authorities to achieve maximum value while managing risk. Examining state efforts to increase the focus on performance and their experiences in responding to recent fiscal stress can offer insights into practices that may assist federal decision makers in addressing the challenges ahead. GAO described for five selected states--Arizona, Maryland, Texas, Virginia, and Washington--legislators' use of performance information in budget deliberations, how performance information helped to inform choices during fiscal stress, challenges these states face in implementing and sustaining their efforts, and the potential for state experiences to inform initiatives to improve the use of performance information at the federal level. Among other factors, these states were selected because they have established histories of performance budgeting efforts and represent a variety of approaches to implementing those efforts."

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2004, Congress appropriated $6.8 billion to serve 919,000 poor children through 1,680 Head Start grantees nationwide. Recent reports of financial improprieties at a number of Head Start programs raised questions about the effectiveness of the oversight by the Department of Health and Human Services' (HHS) Administration for Children and Families (ACF) in identifying and resolving financial management weaknesses in Head Start grantees. In this report, GAO provides information on whether (1) ACF can consistently identify financial management weaknesses, if any, in Head Start grantees and (2) ACF ensures that grantees effectively resolve any problems, in a timely manner, when detected."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, the National Aeronautics and Space Administration (NASA) initiated the Prometheus 1 project to explore the outer reaches of the Solar System. The Prometheus 1 spacecraft is being designed to harness nuclear energy that will increase available electrical power from about 1,000 watts to over 100,000 watts and enable the use of electric propulsion thrusters. Historically, NASA has had difficulty implementing some initiatives. NASA's failure to adequately define requirements and quantify the resources needed to meet those requirements has resulted in some projects costing more, taking longer, and achieving less than originally planned. Prometheus 1 will need to compete for NASA resources with other space missions--including efforts to return the shuttle safely to flight and complete the International Space Station. GAO was asked to determine (1) whether NASA is establishing initial justification for its investment in the Prometheus 1 project and (2) how the agency plans to ensure that critical technologies will be sufficiently mature at key milestones."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1977, the U.S. has entered into bilateral social security totalization agreements with 20 foreign countries. In fiscal year 2004, the Social Security Administration (SSA) paid approximately $206 million to 102,000 beneficiaries in these countries based on their eligible periods of coverage. If put into force, pending agreements with Mexico and Japan will increase the number of beneficiaries receiving totalized benefits, as well as the amount of benefits paid. Given the costs to the Social Security Trust Funds posed by existing and pending agreements, GAO was asked to (1) document SSA's policies and procedures for assessing the accuracy of foreign countries' data when entering into a totalization agreement, and (2) examine SSA's processes for verifying beneficiaries' initial and continuing eligibility for benefits once an agreement is in force."

A letter report issued by the Government Accountability Office with an abstract that begins "Natural catastrophes and terrorist attacks can place enormous financial demands on the insurance industry, result in sharply higher premiums and substantially reduced coverage. As a result, interest has been raised in mechanisms to increase the capacity of the insurance industry to manage these types of events. In this report, GAO (1) provides an overview of the insurance industry's current capacity to cover natural catastrophic risk and discusses the impacts of the 2004 hurricanes; (2) analyzes the potential of catastrophe bonds--a type of security issued by insurers and reinsurers (companies that offer insurance to insurance companies) and sold to institutional investors--and tax-deductible reserves to enhance private-sector capacity; and (3) describes the approaches that six European countries have taken to address natural and terrorist catastrophe risk, including whether these countries permit insurers to use tax-deductible reserves for such events. We provided a draft of this report to the Department of the Treasury and the National Association of Insurance Commissioners. Treasury provided technical comments that were incorporated as appropriate."

A letter report issued by the Government Accountability Office with an abstract that begins "In 1999, the Department of Health and Human Services' (HHS) Centers for Disease Control and Prevention (CDC) began funding jurisdictions' efforts to prepare for bioterrorism attacks through the Public Health Preparedness and Response for Bioterrorism program. After the events of September 11, 2001, and the 2001 anthrax incidents, program funds increased almost twentyfold. Citing jurisdictions' unexpended program funds, HHS reallocated some fiscal year 2004 funds to support other local and national bioterrorism initiatives. Jurisdictions and associations representing jurisdictions disputed HHS's assertion that large amounts of funds remain unused, noting that HHS did not acknowledge obligated funds that had not yet been expended. GAO was asked to provide information on (1) the extent to which jurisdictions had expended the fiscal year 2002 funds awarded for the program's third budget period as of August 30, 2003, and August 31, 2004, and the fiscal year 2003 funds awarded for the program's fourth budget period, as of August 30, 2004; (2) the extent to which fiscal year 2001, 2002, and 2003 funds awarded for the third and fourth budget periods remained unobligated as of August 30, 2004; and (3) factors …

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2004 federal spending on service contracts grew to over $189 billion governmentwide. This growth, along with cuts in the acquisition workforce and increases in high-dollar procurement actions, creates a challenging environment. In November 2003 the Services Acquisition Reform Act (SARA) was enacted to provide federal agencies with tools to optimize mission performance in this challenging environment. To implement the act, regulations and guidance must be developed, and other actions taken. GAO was asked to report on progress in implementing SARA's provisions."

A letter report issued by the Government Accountability Office with an abstract that begins "The Office of Personnel Management (OPM) manages the systems that process retirement benefits for most federal civilian employees. In fiscal year 2003, over 198,000 claims were processed and over $50 billion in benefits was paid through OPM's retirement systems. OPM is trying to modernize these systems through a program called Retirement Systems Modernization (RSM). The conference report accompanying the fiscal year 2004 OPM appropriations act directed us to review the management of and challenges facing RSM. Specifically, our objectives were to determine (1) the current status of and plans for OPM's RSM program and (2) the challenges OPM faces in successfully managing the program."

A letter report issued by the Government Accountability Office with an abstract that begins "Mercury is a toxic element that can cause neurological disorders in children. In January 2004, the Environmental Protection Agency (EPA) proposed two options for limiting mercury from power plants, and plans to finalize a rule in March 2005. The first would require each plant to meet emissions standards reflecting the application of control technology (the technology-based option), while the second would enable plants to either reduce emissions or buy excess credits from other plants (the cap-and-trade option). EPA received over 680,000 written comments on the proposal. EPA is directed by statute and executive order to analyze the costs and benefits of proposed rules, and the agency summarized its analysis underlying the two options in the proposal. In this context, GAO was asked to assess the usefulness of EPA's economic analysis for decision making. In doing so, GAO neither independently estimated the options' costs and benefits nor evaluated the process for developing the options or their consistency with the Clean Air Act, as amended."

Correspondence issued by the Government Accountability Office with an abstract that begins "Combined, the Department of Defense (DOD) and the Department of Veterans Affairs (VA) provide health care services to about 16.8 million beneficiaries at an estimated cost of $58 billion for fiscal year 2005--$30.4 billion for DOD and $27.7 billion for VA. In 1982, the Congress passed the Veterans' Administration and Department of Defense Health Resources Sharing and Emergency Operations Act (Sharing Act) to promote more cost-effective use of health care resources and more efficient delivery of care. Specifically, the Congress authorized DOD and VA to enter into sharing agreements with each other to buy, sell, and barter medical and support services. To further encourage ongoing collaboration, the Congress passed the Bob Stump National Defense Authorization Act (NDAA) for Fiscal Year 2003, which directed the Secretary of Defense and the Secretary of Veterans Affairs to establish a joint incentives program to identify and provide incentives to implement, fund, and evaluate creative health care coordination and sharing initiatives between DOD and VA. Under the program, DOD and VA are to solicit proposals from their program offices, DOD military treatment facilities, or VA medical facilities for project initiatives at least annually. …

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Navy invests significantly to maintain technological superiority of its warships. In 2005 alone, $7.6 billion was devoted to new ship construction in six ship classes--96 percent of which was allocated to four classes: Arleigh Burke class destroyer, Nimitz class aircraft carrier, San Antonio class amphibious transport dock ship, and the Virginia class submarine. Cost growth in the Navy's shipbuilding programs has been a long-standing problem. Over the past few years, the Navy has used "prior year completion" funding--additional appropriations for ships already under contract--to pay for cost overruns. This report (1) estimates the current and projected cost growth on construction contracts for eight case study ships, (2) breaks down and examines the components of the cost growth, and (3) identifies any funding and management practices that contributed to cost growth."

A letter report issued by the Government Accountability Office with an abstract that begins "Drug court programs, which were established in the late 1980s as a local response to increasing numbers of drug-related cases and expanding jail and prison populations, have become popular nationwide in the criminal justice system. These programs are designed to reduce defendants' repeated crime (that is, recidivism), and substance abuse behavior by engaging them in a judicially monitored substance abuse treatment. However, determining whether drug court programs are effective at reducing recidivism and substance use has been challenging because of a large amount of weak empirical evidence. he 21st Century Department of Justice Appropriations Authorization Act requires that GAO assess drug court program effectiveness. To meet this mandate, GAO conducted a systematic review of drug court program research, from which it selected 27 evaluations of 39 adult drug court programs that met its criteria for, among other things, methodological soundness. This report describes the results of that review of published evaluations of adult drug court programs, particularly relating to (1) recidivism outcomes, (2) substance use relapse, (3) program completion, and (4) the costs and benefits of drug court programs. DOJ reviewed a draft of this report …

The original proposal described the construction and operation of a 1 MMscfd nitrogen removal/gas treatment system to be operated at a Butcher Energy gas field in Ohio. The gas produced at this field contained 17% nitrogen. During pre-commissioning of the project, a series of well tests showed that the amount of gas in the field was significantly smaller than expected and that the nitrogen content of the wells was very high (25 to 30%). After evaluating the revised cost of the project, Butcher Energy decided that the plant would not be economical and withdrew from the project. Since that time, Membrane Technology and Research, Inc. (MTR) has signed a marketing and sales partnership with ABB Lummus Global, a large multinational corporation. MTR will be working with the company's Randall Gas Technology group, a supplier of equipment and processing technology to the natural gas industry. Randall's engineering group has found a new site for the project field test at a North Texas Exploration (NTE) gas processing plant. The plant produces about 1 MMscfd of gas containing 24% nitrogen. The membrane unit will bring this gas to 4% nitrogen for delivery to the pipeline. The membrane skid is being built by ABB. …

The contents of Tank 48 that include the tetraphenylborate (TPB) precipitates of potassium and cesium will be grouted and stored in the Saltstone vault. The grouting process is exothermic, which should accelerate the decomposition of TPB precipitates eventually to benzene. Because the vault is not currently outfitted with an active ventilation system, there is a concern that a mixture of flammable gases may form in the vapor space of each cell filled with the curing grout. The purpose of this study was to determine if passive breathing induced by the diurnal oscillations of atmospheric pressure would provide any mitigating measure against potential flammability. Specifically, it was requested that a set of algorithms be developed that would predict the equilibrium concentration of benzene as a function of benzene generation rate, fill height, and the amplitude of the barometric pressure oscillations. These algorithms were to be derived based on several simplifying assumptions so that order of magnitude estimates could be made quickly for scoping purposes. This memo documents the resulting algorithms along with those key assumptions made. These algorithms were then applied to simulate several test cases, including the baseline case where the cell was filled to the maximum height of 25 …

The design concept is designated the ''Porous Wall Radiation Barrier'' heating mantle. In this design, combustion gas flows through a porous wall surrounding the retort, transferring its heat to the porous wall, which then radiates heat energy to the retort. Experiments demonstrate that heat transfer rates of 1.8-2.4 times conventional gas fired mantles are achievable in the temperature range of 1600-2350 degrees fahrenheit.

Mechanically alloyed oxide dispersion strengthened (ODS) Fe-Cr-Al alloy thin walled tubes and sheets, produced via powder processing and consolidation methodologies, are promising materials for eventual use at temperatures up to 1200 C in the power generation industry, far above the temperature capabilities of conventional alloys. Target end-uses range from gas turbine combustor liners to high aspect ratio (L/D) heat exchanger tubes. Grain boundary creep processes at service temperatures, particularly those acting in the hoop direction, are the dominant failure mechanisms for such components. The processed microstructure of ODS alloys consists of high aspect ratio grains aligned parallel to the tube axis, a result of dominant axial metal flow which aligns the dispersoid particles and other impurities in the longitudinal direction. The dispersion distribution is unaltered on a micro scale by recrystallization thermal treatments, but the high aspect ratio grain shape typically obtained limits transverse grain spacing and consequently the hoop creep response. Improving hoop creep in ODS-alloy components will require understanding and manipulating the factors that control the recrystallization behavior, and represents a critical materials design and development challenge that must be overcome in order to fully exploit the potential of ODS alloys. The objectives of this program are to …

Plasma Processing of Advanced Materials The project had the overall objective of improving our understanding of the influences of process parameters on the properties of advanced superhard materials. The focus was on high rate deposition processes using thermal plasmas and atmospheric pressure glow discharges, and the emphasis on superhard materials was chosen because of the potential impact of such materials on industrial energy use and on the environment. In addition, the development of suitable diagnostic techniques was pursued. The project was divided into four tasks: (1) Deposition of superhard boron containing films using a supersonic plasma jet reactor (SPJR), and the characterization of the deposition process. (2) Deposition of superhard nanocomposite films in the silicon-nitrogen-carbon system using the triple torch plasma reactor (TTPR), and the characterization of the deposition process. (3) Deposition of films consisting of carbon nanotubes using an atmospheric pressure glow discharge reactor. (4) Adapting the Thomson scattering method for characterization of atmospheric pressure non-uniform plasmas with steep spatial gradients and temporal fluctuations. This report summarizes the results.
