A letter report issued by the General Accounting Office with an abstract that begins "Each year thousands of international science students and scholars apply for visas to enter the United States to participate in education and exchange programs. They offer our country diversity and intellectual knowledge and are an economic resource. At the same time, the United States has important national security interests in screening these individuals when they apply for a visa. At a hearing held by the House Committee on Science on March 26, 2003, witnesses raised concern about the length of time it takes for science students and scholars to obtain a visa and about losing top international students to other countries due to delays in the visa process. GAO reviewed 1) how long it takes a science student or scholar from another country to obtain a visa and the factors contributing to the length of time, and 2) what measures are under way to improve the process and decrease the number of pending cases."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Justice's Federal Bureau of Prisons (BOP) is responsible for the custody and care of more than 202,000 federal offenders with approximately 35,000 employees, almost half of whom are correctional officers, dispersed across BOP's 114 correctional facilities in 6 regions. In response to a request, GAO identified whether BOP had policies and procedures and how it assessed the management of those policies and procedures for (1) employee-requested lateral transfers of BOP employees between correctional facilities and (2) day-to-day changes in correctional services or temporary assignments of BOP employees within a correctional facility. GAO reviewed available documentation on BOP's policies and procedures on lateral transfers and temporary assignments. GAO also interviewed officials from BOP's central and regional offices and seven facilities selected on the basis of the number of staff; at least one facility was selected from within each of BOP's six regions."

A letter report issued by the Government Accountability Office with an abstract that begins "To protect the government's interests, any agency can exclude (i.e., debar or suspend) parties from receiving federal contracts or assistance for a range of offenses. Exclusions of companies or individuals from federal contracts or other funding are listed in the Excluded Parties List System (EPLS), a Web-based system maintained by GSA. Recent allegations indicate that excluded parties have been able to receive federal contracts. As a result, GAO was asked (1) to determine whether these allegations could be substantiated and (2) to identify the key causes of any improper awards and other payments detected. GAO investigated parties that were excluded for offenses such as fraud, theft, and violations of federal statutes and received awards in excess of $1,000."

A letter report issued by the General Accounting Office with an abstract that begins "The Army wants an artillery system with greater firepower, range, and mobility than its current self-propelled howitzer. In 1994, the Army began to develop the Crusader, an advanced artillery system consisting of a self-propelled 155-millimeter howitzer and a resupply vehicle. The Department of Defense (DOD) will decide next year whether the Crusader program should enter its system development and demonstration stage, which will require the commitment of major resources. GAO found that the Crusader program has made considerable progress in developing key technologies and reducing its size and weight. However, more progress and knowledge is needed to minimize the risk of cost overruns, schedule delays, and performance shortfalls. The Crusader program will likely enter product development with most of its critical technologies less mature than best practices recommend. Most of the Crusader's critical technologies have been demonstrated in a relevant environment but not in the more demanding operational environment. Although the Army is reducing the Crusader's weight so that two vehicles can be deployed on a C-17 aircraft, the deployability advantage gained does not appear significant. The reduction in the Crusader system's weight would only decrease …

A letter report issued by the Government Accountability Office with an abstract that begins "Health-care-associated infections (HAI) are a leading cause of death. Recent high-profile cases of HAIs in ambulatory surgical centers (ASC) due to lapses in recommended infection control practices may indicate a more widespread problem in ASCs, but the prevalence of such lapses is unknown. The Department of Health and Human Services' (HHS) Centers for Medicare & Medicaid Services (CMS) and other entities collect data on HAIs, including process data on the use of recommended practices and outcome data on HAI incidence. CMS conducts standard surveys on about half of ASCs every 3 to 4 years, assessing compliance with its standard on infection control. In this report, GAO examines the availability of data on HAIs in ASCs nationwide. GAO interviewed subject-matter experts, agency officials, and trade and professional group officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Diabetes, which afflicts millions of Americans, is a manageable disease whose effects can be mitigated with proper care, regularly received. Experts recommend certain services and supplies for managing diabetes. Because these can be costly, concerns exist about whether individuals with diabetes have access to and receive what they need. Little is known, however, about health plan coverage of diabetes services and supplies. GAO reviewed the extent to which (1) states require insurance policies to cover diabetes services and supplies, (2) health coverage not subject to state requirements includes diabetes services and supplies, and (3) individuals with diabetes ages 18 and older receive services and supplies. GAO analyzed all 50 states' and the District of Columbia's laws and regulations pertaining to diabetes coverage. GAO also obtained from selected health plans providing coverage not subject to state requirements--13 large-employer plans and 3 plans in the Federal Employees Health Benefits Program (FEHBP)--information on coverage of 10 services and nine supplies identified as important for individuals with diabetes. In addition, GAO obtained national data from the Centers for Disease Control and Prevention (CDC) on individuals' receipt of diabetes services and …

A letter report issued by the Government Accountability Office with an abstract that begins "Invasive weeds, native or nonnative plant species, cause harm to natural areas such as rangelands or wildlife habitat and economic impacts due to lost productivity of these areas. While the federal investment in combating invasive species is substantial most has been concentrated on agricultural lands, not on natural areas. In this report, GAO describes (1) the entities that address invasive weeds in natural areas and the funding sources they use; (2) federal, state, and local weed management officials' views on the barriers to weed management; and (3) their opinions about how additional resources for weed management could be distributed. GAO limited this study to entities in the Departments of Agriculture and the Interior, and California, Colorado, Idaho, Maryland, and Mississippi, and gathered information through interviews of over 90 weed management officials."

A letter report issued by the Government Accountability Office with an abstract that begins "An institute at the National Institutes of Health (NIH) and an office in the Environmental Protection Agency (EPA) entered into collaborative arrangements with the American Chemistry Council (ACC) to support research on the health effects of chemical exposures. NIH accepted a gift from ACC to help fund the research. EPA and ACC funded their proposals separately. The arrangements raised concerns about the potential for ACC to influence research that could affect the chemical industry. GAO determined the agencies' legal authorities to enter into the arrangements; the extent to which the agencies evaluated and managed potential conflicts of interest resulting from these arrangements; the extent to which the NIH institute complied with NIH's gift acceptance policy; and the extent to which NIH, EPA, and other agencies have similar arrangements."

A letter report issued by the Government Accountability Office with an abstract that begins "Individual taxpayers used commercial tax software to prepare over 39 million tax returns in 2007, making it critical to the tax administration system. The majority were then filed electronically, resulting in fewer errors and reduced processing costs compared to paper returns. GAO was asked to assess what is known about how pricing of tax software influences electronic filing, the extent to which the Internal Revenue Service (IRS) provides oversight of the software industry, and the risks to tax administration from using tax software. To do so, GAO analyzed software prices, met with IRS and software company officials, examined IRS policies, and reviewed what is known about the accuracy, security, and reliability of tax software."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2000, Congress authorized the U.S. Department of Agriculture's Forest Service to allow the Colorado State Forest Service to conduct certain activities, such as reducing hazardous vegetation, on U.S. Forest Service land when performing similar activities on adjacent state or private land. The Department of the Interior's Bureau of Land Management (BLM) received similar "Good Neighbor" authority in 2004, as did the U.S. Forest Service in Utah. Congress has also considered the authority's expansion to other states. GAO was asked to determine (1) the activities conducted under the authority; (2) the federal and state guidance, procedures, and controls used to conduct Good Neighbor projects; and (3) successes, challenges, and lessons learned resulting from the authority's use. To do so, GAO reviewed Good Neighbor project documentation and interviewed federal and state officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Under the Public Utility Holding Company Act of 1935 (PUHCA 1935) and other laws, federal agencies and state commissions have traditionally regulated utilities to protect consumers from supply disruptions and unfair pricing. The Energy Policy Act of 2005 (EPAct) repealed PUHCA 1935, removing some limitations on the companies that could merge with or invest in utilities, leaving the Federal Energy Regulatory Commission (FERC), which already regulated utilities, with primary federal responsibility for regulating them. Because of the potential for new mergers or acquisitions between utilities and companies previously restricted from investing in utilities, there has been considerable interest in whether cross-subsidization--unfairly passing on to consumers the cost of transactions between utility companies and their "affiliates"--could occur. GAO was asked to (1) examine the extent to which FERC changed its merger and acquisition and post merger review and oversight processes since EPAct to protect against cross-subsidization and (2) survey state utility commissions about their oversight."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO: (1) reviewed the application of the Federal Claims Collection Act to the Health Care Financing Administration's (HCFA) settlement of overpayment matters with providers; and (2) developed case studies of settlements that may have been improper."

A letter report issued by the General Accounting Office with an abstract that begins "The central banks of major industrialized countries have agreed on common policy objectives and presented them in the Core Principles for Systematically Important Payment Systems. Intended to help promote safer and more efficient payment systems worldwide, the Core Principles outline specific policy recommendations for systematically important payment systems and describe the responsibilities of the central banks. All of the central banks GAO studied seek to ensure that their wholesale payment systems operate smoothly and minimize systemic risk. All of the central banks provide settlement services for their countries' wholesale payment systems. Some central banks also provide wholesale clearing services. Other central banks own the system but have little operational involvement in clearing, while others participate in partnerships with the private sector. All of the central banks GAO studied provide settlement for some retail payment systems. Some, but not all, central banks exercise regulatory authority over retail payment systems in their countries. Central banks also tend to have less operational involvement in countries where there is a relatively concentrated banking industry. In some cases, laws governing payments and the structure of the financial services industry direct the …

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the status of the Bureau of the Census' Be Counted and Questionnaire Assistance Center programs, focusing on the steps the Bureau has taken to address certain shortcomings that the Bureau encountered during the dress rehearsal for the 2000 Census."

A letter report issued by the Government Accountability Office with an abstract that begins "More than 5 million cattle across Europe have been killed to stop the spread of bovine spongiform encephalopathy (BSE), commonly called mad cow disease. Found in 26 countries, including Canada and the United States, BSE is believed to spread through animal feed that contains protein from BSE-infected animals. Consuming meat from infected cattle has also been linked to the deaths of about 150 people worldwide. In 1997, the Food and Drug Administration (FDA) issued a feed-ban rule prohibiting certain animal protein (prohibited material) in feed for cattle and other ruminant animals. FDA and 38 states inspect firms in the feed industry to enforce this critical firewall against BSE. In 2002, GAO reported a number of weaknesses in FDA's enforcement of the feed ban and recommended corrective actions. This report looks at FDA's efforts since 2002 to ensure industry compliance with the feed ban and protect U.S. cattle."

This 2001 Facility Work Plan (FWP) has been prepared as required by Module VII, Section VII.M.1 of the Waste Isolation Pilot Plant (WIPP) Hazardous Waste Facility Permit, NM4890139088-TSDF (the Permit); (NMED, 1999a), and incorporates comments from the New Mexico Environment Department (NMED) received on December 6, 2000 (NMED, 2000a). This February 2001 FWP describes the programmatic facility-wide approach to future investigations at Solid Waste Management Units (SWMUs) and Areas of Concern (AOCs) specified in the Permit. The permittees are evaluating data from previous investigations of the SWMUs and AOCs against the newest guidance proposed by the NMED. Based on these data, the permittees expect that no further sampling will be required and that a request for No Further Action (NFA) at the SWMUs and AOCs will be submitted to the NMED. This FWP addresses the current Permit requirements. It uses the results of previous investigations performed at WIPP and expands the investigations as required by the Permit. As an alternative to the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) specified in Module VII of the Permit, current NMED guidance identifies an Accelerated Corrective Action Approach (ACAA) that may be used for any SWMU or AOC (NMED, 1998). This …

This Hazardous Waste Management Act/Resource Conservation and Recovery Act closure plan was developed for the laboratory components of the Test Reactor Area Catch Tank System (TRA-630) that are located in the Materials Test Reactor Wing (TRA-604) at the Reactor Technology Complex, Idaho National Laboratory Site, to meet a further milestone established under Voluntary Consent Order Action Plan VCO-5.8.d. The TRA-604 laboratory components addressed in this closure plan were deferred from the TRA-630 Catch Tank System closure plan due to ongoing laboratory operations in the areas requiring closure actions. The TRA-604 laboratory components include the TRA-604 laboratory warm wastewater drain piping, undersink drains, subheaders, and the east TRA-604 laboratory drain header. Potentially contaminated surfaces located beneath the TRA-604 laboratory warm wastewater drain piping and beneath the island sinks located in Laboratories 126 and 128 (located in TRA-661) are also addressed in this closure plan. The TRA-604 laboratory components will be closed in accordance with the interim status requirements of the Hazardous Waste Management Act/Resource Conservation and Recovery Act as implemented by the Idaho Administrative Procedures Act 58.01.05.009 and 40 Code of Federal Regulations 265, Subparts G and J. This closure plan presents the closure performance standards and the methods for achieving …

The STAR Collaboration proposes to construct a state-of-the-art microvertex detector,the Heavy Flavor Tracker (HFT), utilizing active pixel sensors and silicon strip technology. The HFT will significantly extend the physics reach of the STAR experiment for precision measurement of the yields and spectra of particles containing heavy quarks. This will be accomplished through topological identification of D mesons by reconstruction of their displaced decay vertices with a precision of approximately 50 mu m in p+p, d+A, and A+A collisions. The HFT consists of 4 layers of silicon detectors grouped into two sub-systems with different technologies, guaranteeing increasing resolution when tracking from the TPC and the Silicon Strip Detector (SSD) towards the vertex of the collision. The Intermediate Silicon Tracker (IST), consisting of two layers of single-sided strips, is located inside the SSD. Two layers of Silicon Pixel Detector (PIXEL) are inside the IST. The PIXEL detectors have the resolution necessary for a precision measurement of the displaced vertex. The PIXEL detector will use CMOS Active Pixel Sensors (APS), an innovative technology never used before in a collider experiment. The APSsensors are only 50 mu m thick and at a distance of only 2.5 cm from the interaction point. This opens up …

The Hanford External Dosimetry Technical Basis Manual PNL-MA-842 documents the design and implementation of the external dosimetry system used at Hanford. The manual describes the dosimeter design, processing protocols, dose calculation methodology, radiation fields encountered, dosimeter response characteristics, limitations of dosimeter design under field conditions, and makes recommendations for effective use of the dosimeters in the field. The manual describes the technical basis for the dosimetry system in a manner intended to help ensure defensibility of the dose of record at Hanford and to demonstrate compliance with 10 CFR 835, DOELAP, DOE-RL, ORP, PNSO, and Hanford contractor requirements. The dosimetry system is operated by PNNL’s Hanford External Dosimetry Program which provides dosimetry services to all Hanford contractors. The primary users of this manual are DOE and DOE contractors at Hanford using the dosimetry services of PNNL. Development and maintenance of this manual is funded directly by DOE and DOE contractors. Its contents have been reviewed and approved by DOE and DOE contractors at Hanford through the Hanford Personnel Dosimetry Advisory Committee which is chartered and chaired by DOE-RL and serves as means of coordinating dosimetry practices across contractors at Hanford. This manual was established in 1996. Since inception, it has …

This Facility Work Plan (FWP) has been prepared as required by Module VII,Section VII.M.1 of the Waste Isolation Pilot Plant (WIPP) Hazardous Waste Permit, NM4890139088-TSDF (the Permit); (NMED, 1999a). This work plan describes the programmatic facility-wide approach to future investigations at Solid Waste Management Units (SWMUs) and Areas of Concern (AOCs) specified in the Permit. This FWP addresses the current Permit requirements. It uses the results of previous investigations performed at WIPP and expands the investigations as required by the Permit. As an alternative to the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) specified in Module VII of the Permit, current New Mexico Environment Department (NMED) guidance identifies an Accelerated Corrective Action Approach (ACAA) that may be used for any SWMU or AOC (NMED, 1998). This accelerated approach is used to replace the standard RFI Work Plan and Report sequence with a more flexible decision-making approach. The ACAA process allows a Facility to exit the schedule of compliance contained in the Facility’s Hazardous and Solid Waste Amendments (HSWA) permit module and proceed on an accelerated time frame. Thus, the ACAA process can be entered either before or after an RFI Work Plan. According to NMED’s guidance, a facility …

At first glance the story of the Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory (ANL) appears to have followed a puzzling course. When researchers first proposed their ideas for an accelerator-driven neutron source for exploring the structure of materials through neutron scattering, the project seemed so promising that both Argonne managers and officials at the laboratory's funding agency, the Department of Energy (DOE), suggested that it be made larger and more expensive. But then, even though prototype building, testing, and initial construction went well a group of prominent DOE reviewers recommended in fall 1980 that it be killed, just months before it had been slated to begin operation, and DOE promptly accepted the recommendation. In response, Argonne's leadership declared the project was the laboratory's top priority and rallied to save it. In late 1982, thanks to another review panel led by the same scientist who had chaired the panel that had delivered the death sentence, the project was granted a reprieve. However, by the late 1980s, the IPNS was no longer top priority within the international materials science community, at Argonne, or within the DOE budget because prospects for another, larger materials science accelerator emerged. At just this …

We performed computational simulations and theoretical analysis to investigate the underlying origins of large thermal conductivity enhancements observed in nanofluids (colloidal suspensions of solid nanoparticles and/or nanofibers in thermal fluids) and to identify strategies towards tailoring nanofluids for better thermal performance.

The objectives of the radiological scoping survey were to collect adequate field data for use in evaluating the radiological condition of Scotia Depot land areas, warehouses, and support buildings.
