A letter report issued by the General Accounting Office with an abstract that begins "The Veterans Benefits Administration (VBA) provided $23 billion in monthly cash benefits to 3.2 million disabled veterans and their families through its compensation and pension program in fiscal year 2001. In the same year, VBA mailed 1.2 million "notification" letters to veterans and their families, informing them of VBA's decisions on compensation or pension benefits claims filed. VBA also sent 1.2 million "development" letters in fiscal year 2001 requesting information in order to make a decision on claims. VBA found in 1995 that its notification and development letters failed to communicate adequately, and launched an initiative, called Reader-Focused Writing, to improve its written communications. In its letters, VBA clearly explained some, but not all, of the key aspects that claimants needed to understand. Beyond the lack of clarity in these letters, various writing deficiencies, such as sequencing and formatting problems, reduced the value of VBA's letters. First, in many of its rating decision documents and development letters, VBA attempts to achieve more than one objective and, in doing so, compromises clarity for the reader. Second, although VBA's central office and some regional offices have developed boilerplate …

A letter report issued by the General Accounting Office with an abstract that begins "United Nations sanctions were first imposed in August 1990 following Iraq's invasion of Kuwait. In 1991, the Security Council established sanctions to stop Iraq from acquiring or developing biological, chemical, and nuclear weapons. To achieve this, the Security Council prohibited all nations from buying Iraqi oil or selling the country any commodities except for food and medicine. It further established a weapons inspection regime to ensure that Iraq destroyed its weapons of mass destruction and stopped its weapons programs. Concerned about the humanitarian need of the Iraqi people, in 1995 the Security Council established a controls program for Iraq's oil sales that allows for the purchase of food, medicine, and essential civilian goods (the oil for food program). With international support for the sanctions eroding, in 2001 the Security Council passed a new sanctions resolution to address humanitarian concerns while keeping Iraq from rebuilding its weapons systems. Although the U.N. controlled $51 billion of Iraq's oil revenues from 1997 to 2001, Iraq earned an additional $6.6 billion in illegal revenue from oil smuggling and surcharges during the same time. Further, although the sanctions prohibit Iraq from …

A letter report issued by the General Accounting Office with an abstract that begins "The mission of the National Nuclear Security Administration's (NNSA) Nonproliferation and Verification Research and Development (R&D) Program is to conduct needs-driven research, development, testing, and evaluation of new technologies that are intended to strengthen the United States' ability to prevent and respond to nuclear, chemical, and biological attacks. In fiscal years 1998 through 2002, the Nonproliferation and Verification R&D program received an average of $218 million per year--a total of $1.2 billion. Nearly 75 percent of that total was distributed for R&D at three NNSA national laboratories. Two of the three research areas of the Nonproliferation and Verification R&D Program lack a formal process to identify users' needs, and the tools used to monitor project progress are inadequate. In terms of users, NNSA's role is to develop technologies for, and transfer them to, users in the federal government, the intelligence community, law enforcement, and others. The program requires that projects' life-cycle plans and quarterly reports contain detailed information on project time frames, milestones, users of technologies, and deliverables. Officials from federal, state, and local agencies that use the technology developed by NNSA's R&D program have found …

A letter report issued by the General Accounting Office with an abstract that begins "In 1998, the Health Care Financing Administration implemented a prospective payment system (PPS) for skilled nursing facility (SNF) services provided to Medicare beneficiaries. PPS is intended to control the growth in Medicare spending for skilled nursing and rehabilitative services that SNFs provide. Two years after the implementation of PPS, the mix of patients across the categories of payment groups has shifted, as determined by the patients' initial minimum data set assessments. Although the overall share of patients classified into rehabilitation payment group categories based on their initial assessments remained about the same, more patients were classified into the high and medium rehabilitation payment group categories, and fewer were initially classified into the most intensive (highest paying) and least intensive (lowest paying) rehabilitation payment group categories. Two years after PPS was implemented the majority of patients in rehabilitation payment groups received less therapy than was provided in 1999. This was true even for patients within the same rehabilitation payment group categories. Across all rehabilitation payment group categories, fewer patients received the highest amounts of therapy associated with each payment group."

A briefing report issued by the General Accounting Office with an abstract that begins "The attacks of September 11, 2001, and recent anthrax exposures have heightened long-standing concerns about the proliferation of biological weapons and the United States' ability to quickly respond to such incidents. The United States must identify technologies to protect against biological weapons, such as anthrax, without harming humans. Ionizing radiation has emerged as the leading current technology for mail sanitization. However, ionizing radiation may have adverse effects on mailed material, and it may not be applicable to some types of parcels, boxes, and large packages. In addition, applying ionizing radiation in a mail-processing environment requires radiation and biohazard precautions, such as shielding the radiation source and wearing protective gear."

A letter report issued by the General Accounting Office with an abstract that begins "Several federal programs have been developed to provide homeownership opportunities for Native Americans because private institutions have rarely supplied conventional home loans to Native Americans on trust lands. In 1992, Congress directed the Department of Veterans Affairs (VA) to create the Native American Veterans Direct Home Loan Program to assist veterans in purchasing, constructing and improving homes. The Native American Veterans Direct Home Loan Program has been characterized by differences in the numbers served, with native Hawaiians and Pacific Islanders together receiving almost five times as many as loans as Native Americans. Several factors that apply to Native Americans, but not to native Hawaiians and Pacific Islanders, may explain this difference. Long-standing barriers to lending on Native American trust lands include insufficient income and credit history, a lack of meaningful interest in land among many Native Americans, and insufficient infrastructure on trust lands. Other factors that VA can address include program limits that may be lower than housing costs for some trust lands and potential applicants' inexperience with the mortgage lending process. VA has conducted outreach but has taken limited steps to meet the assessment and …

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) estimates that cleaning up contamination and hazards at thousands of properties that it formerly owned or controlled will take more than 70 years and cost as much as $20 billion. These formerly used defense sites (FUDS), which can range in size from less than an acre to many thousands of acres, are now used for parks, farms, schools, and homes. Hazards at these properties include unsafe buildings, toxic and radioactive wastes, containerized hazardous wastes, and ordnance and explosive wastes. The U.S. Army Corps of Engineers is responsible for identifying, investigating, and cleaning up hazards resulting from military use. GAO found that the Corps lacks a sound basis for its conclusion that 38 percent of 3,840 FUDS need no further study or cleanup action. The Corps' determinations are questionable because there is no evidence that it reviewed or obtained information that would allow it to identify all the potential hazards at the properties, or that it took sufficient steps to assess the presence of potential hazards. GAO also found that the Corps often did not notify owners of its determinations that the …

A letter report issued by the General Accounting Office with an abstract that begins "The United States is increasingly dependent on space for its security and well being. The Department of Defense's (DOD) space systems collect information on capabilities and intentions of potential adversaries. They enable military forces to be warned of a missile attack and to communicate and navigate while avoiding hostile action. DOD's efforts to strengthen space control are targeted at seeking to promote better coordination among DOD components, prioritization of projects, visibility and accountability over funding, and interoperability among systems. Among other things, DOD is drafting a space control strategy that is to outline objectives, tasks, and capabilities for the next 20 years. It has also aggregated funding for space programs so that it can compare space funding, including space control funding, to its total budget, make decisions about priorities, and conduct future-trend analyses. In addition, DOD has changed its acquisition policy to include separating technology development from product development and encouraging an evolutionary, or phased, approach to development. There are, however, substantial challenges to making DOD's space control efforts successful. One challenge is putting needed plans in place to provide direction and hold the services accountable …

A letter report issued by the General Accounting Office with an abstract that begins "The U.S. Patent and Trademark Office (USPTO) has a staff of 6,426 and collected $1.1 billion in patent and trademark fees in fiscal year 2001. As the U.S. economy depends increasingly on new innovations, the need to patent or trademark quickly the intellectual property resulting from such innovations becomes more important. Expressing concerns about USPTO's plans for the future, Congress directed USPTO to develop a 5-year plan. In February 2001, USPTO issued its first 5-year plan, called the USPTO Business Plan. Because the Director of USPTO did not believe that the Business Plan went far enough, in June 2002, USPTO produced another 5-year plan, called the 21st Century Strategic Plan. GAO found that patent activity grew substantially from 1990 through 2001. The numbers of patent applications filed and patents granted nearly doubled; the inventory of patent applications nearly tripled; patent pendency increased from slightly over 18 months to nearly 25 months, and the number of patent examiners increased by about 80 percent. Furthermore, in fiscal year 2001, both fee collections and agency funding requirements exceeded $1 billion for the first time in the agency's history. Although …

A letter report issued by the General Accounting Office with an abstract that begins "Poor oversight and management of DOD's travel card program has led to high delinquency rates, costing DOD millions in lost rebates and increased ATM fees. As a result, the Congress asked GAO to report on (1) the magnitude, impact, and cause of delinquencies, (2) the types of fraudulent and abusive uses of the travel card, and (3) the effectiveness of internal controls over DOD's travel card program. GAO previously reported on travel card management at the Army. This report focuses on travel card management at the Navy, including the Marine Corps."

A letter report issued by the General Accounting Office with an abstract that begins "China's entry into the World Trade Organization (WTO) on December 11, 2001, brought the world's seventh largest economy under global trade liberalizing rules. If implemented, China's commitments will open China's economy and reform its trading activities, thereby expanding U.S. companies' opportunities for investing in China and for exporting goods, agricultural products, and services to China. Understanding U.S. companies' expectations is fundamental for policymakers to judge the degree to which the benefits of China's WTO membership are being realized. GAO analyzed U.S. companies' views about (1) the importance of, (2) the anticipated effects of, and (3) prospects for China implementing its WTO commitments. GAO surveyed a random sample of 551 U.S. companies and interviewed 48 judgmentally selected companies in four cities in China. Survey results reflect responses from 191 companies--a response rate of 38 percent--and may not reflect the views of all U.S. companies with activities in China."

A letter report issued by the General Accounting Office with an abstract that begins "The Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996 changed the nation's cash assistance program for needy families with children by replacing the Aid to Families with Dependent Children program, with the Temporary Assistance for Needy Families (TANF) block grant. As specified in PRWORA, TANF's goals include ending the dependence of families receiving government benefits by promoting job preparation, work, and marriage; preventing and reducing the incidence of non-marital pregnancies; and encouraging two-parent families. Contracting with nongovernmental entities to provide TANF-funded services occurs in most states and exceeded $1.5 billion in federal and state funds in 2001. A GAO survey indicated that the most commonly contracted services included education and training, job placement, and support services to promote job entry or retention. The Department of Health and Human Services (HHS) relies primarily on state single audit reports to oversee TANF contracting by states and localities. HHS officials told GAO that their regional offices follow up on the TANF deficiencies identified and that HHS focuses on reported deficiencies that involve unallowable or questionable costs. However, HHS officials said that they do not know the extent …

A general methodology was developed for evaluation of carbon sequestration technologies. In this document, we provide a method that is quantitative, but is structured to give qualitative comparisons despite changes in detailed method parameters, i.e., it does not matter what ''grade'' a sequestration technology gets but a ''better'' technology should receive a better grade. To meet these objectives, we developed and elaborate on the following concepts: (1) All resources used in a sequestration activity should be reviewed by estimating the amount of greenhouse gas emissions for which they historically are responsible. We have done this by introducing a quantifier we term Full-Cycle Carbon Emissions, which is tied to the resource. (2) The future fate of sequestered carbon should be included in technology evaluations. We have addressed this by introducing a variable called Time-adjusted Value of Carbon Sequestration to weigh potential future releases of carbon, escaping the sequestered form. (3) The Figure of Merit of a sequestration technology should address the entire life-cycle of an activity. The figures of merit we have developed relate the investment made (carbon release during the construction phase) to the life-time sequestration capacity of the activity. To account for carbon flows that occur during different times …

A series of laser welds were performed using a high-power diode-pumped continuous-wave Nd:YAG laser welder. In a previous study, the experimental results of those welds were examined, and the effects that changes in incident power and various welding parameters had on weld geometry were investigated. In this report, the fusion zones of the laser welds are compared with those predicted from a laser keyhole weld simulation model for stainless steels (304L and 21-6-9), vanadium, and tantalum. The calculated keyhole depths for the vanadium and 304L stainless steel samples fit the experimental data to within acceptable error, demonstrating the predictive power of numerical simulation for welds in these two materials. Calculations for the tantalum and 21-6-9 stainless steel were a poorer match to the experimental values. Accuracy in materials properties proved extremely important in predicting weld behavior, as minor changes in certain properties had a significant effect on calculated keyhole depth. For each of the materials tested, the correlation between simulated and experimental keyhole depths deviated as the laser power was increased. Using the model as a simulation tool, we conclude that the optical absorptivity of the material is the most influential factor in determining the keyhole depth. Future work will …

This report describes the results from an experimental program to investigate the feasibility of laser produced MeV protons as a diagnostic of electric fields or shock compressed materials. The experimental campaign was very successful, and has led to substantial advances in the characterization and optimization of proton sources from ultra-intense laser-solid interaction. This is a subject of the highest scientific interest [1] and is highly relevant to developing its use as a possible NIF implosion diagnostic and other applications relevant to stockpile stewardship.

This report considers the constitutionality of federal tort reform legislation, such as the products liability and medical malpractice reform proposals that have been introduced for the last several Congresses.

Traditionally, the 'Apterygota' has been thought to consist of five orders of wingless hexapods (Protura, Collembola, Diplura, Microcoryphia and Zygentoma) believed to be collectively basal to insects (i.e., the Pterygota). However, some studies have questioned this affinity with insects (Dallai, Abele, Spears, Nardi). Further, within these groups are hotly debated issues, including the monophyly of Entognata (Koch, 1997; Kukalova Peck, 1987), the monophyly of Diplura (Bilinski, 1993; Stys and Bilinski, 1990), the affinity between Collembola and Protura (Dallai, 1994; Kristensen, 1981) and the position of Lepidotrichidae (below). In fact, these relationships constitute one of the most debated issues in hexapod phylogeny. The family Lepidotrichidae was first described by (Silvestri, 1912) (1912: 'Lepidothricinae') from a Baltic Amber fossil (Lepidothrix pilifera Menge). The only living representative of this family is Tricholepidion gertschi Wygodzinski. Since this species was first described (Wygodzinsky, 1961) its phylogenetic position has been difficult to establish, due to an 'array of unique characters' that are difficult to interpret in a phylogenetic framework. Tricholepidion (and therefore the whole family Lepidotrichidae) has been considered either as belonging to the order Zygentoma (Kristensen, 1997; Wygodzinsky, 1961), or basal to the rest of the Zygentoma plus the Pterygota (Beutel, 2001; Bitsch and Bitsch, …

Here, we report a maximum ATP synthesis rate of 193 nmol/min/mg for thermophilic F{sub 1}F{sub 0}. This rate is somewhat lower than the previously observed maximum rate of 500-700 nmol/min/mg (Pitard et al., 1996). However, ATP synthesis rates vary considerably with experimental conditions, and our observed rates compare favorably with the wide range of rates (40-700 nmol/min/mg) observed by these authors. Future research will focus on maximizing the ATP synthesis rate by adjusting environmental conditions, including the lipid and cholesterol composition of the proteoliposomes.

Uncertainties in the predicted isotopic concentrations in spent nuclear fuel represent one of the largest sources of overall uncertainty in criticality calculations that use burnup credit. The methods used to propagate the uncertainties in the calculated nuclide concentrations to the uncertainty in the predicted neutron multiplication factor (k{sub eff}) of the system can have a significant effect on the uncertainty in the safety margin in criticality calculations and ultimately affect the potential capacity of spent fuel transport and storage casks employing burnup credit. Methods that can provide a more accurate and realistic estimate of the uncertainty may enable increased spent fuel cask capacity and fewer casks needing to be transported, thereby reducing regulatory burden on licensee while maintaining safety for transporting spent fuel. This report surveys several different best-estimate strategies for considering the effects of nuclide uncertainties in burnup-credit analyses. The potential benefits of these strategies are illustrated for a prototypical burnup-credit cask design. The subcritical margin estimated using best-estimate methods is discussed in comparison to the margin estimated using conventional bounding methods of uncertainty propagation. To quantify the comparison, each of the strategies for estimating uncertainty has been performed using a common database of spent fuel isotopic assay measurements …

This report presents studies performed to support the development of a technically justifiable approach for addressing the axial-burnup distribution in pressurized-water reactor (PWR) burnup-credit criticality safety analyses. The effect of the axial-burnup distribution on reactivity and proposed approaches for addressing the axial-burnup distribution are briefly reviewed. A publicly available database of profiles is examined in detail to identify profiles that maximize the neutron multiplication factor, k{sub eff}, assess its adequacy for PWR burnup credit analyses, and investigate the existence of trends with fuel type and/or reactor operations. A statistical evaluation of the k{sub eff} values associated with the profiles in the axial-burnup-profile database was performed, and the most reactive (bounding) profiles were identified as statistical outliers. The impact of these bounding profiles on k{sub eff} is quantified for a high-density burnup credit cask. Analyses are also presented to quantify the potential reactivity consequence of loading assemblies with axial-burnup profiles that are not bounded by the database. The report concludes with a discussion on the issues for consideration and recommendations for addressing axial burnup in criticality safety analyses using burnup credit for dry cask storage and transportation.
