A letter report issued by the General Accounting Office with an abstract that begins "Although Social Security's benefit and contribution provisions are neutral with respect to race, ethnicity, and gender, concerns about the experiences of minority groups under Social Security focus on whether they benefit less than whites, particularly because of the shorter life expectancy of blacks. These concerns are related to the concept of equity, or how benefits compare with taxes. To gain a thorough understanding of the experiences of minority populations under Social Security, GAO was asked to examine (1) what socioeconomic and demographic factors influence Social Security taxes paid and benefits received and (2) how different equity measures compare across racial groups. Because of the current system's projected actuarial deficit, to conduct this study, GAO made its calculations using three policy scenarios, each of which achieves 75-year solvency: a payroll tax increase and a progressive and proportional benefit cut. Further, GAO used three measures of equity: lifetime benefit-to-tax ratios, net lifetime benefits, and real internal rates of return. GAO also examined four birth cohorts: 1931-40, 1941-45, 1946-55, and 1956-64."

A letter report issued by the General Accounting Office with an abstract that begins "Women and children refugees, who comprise 80 percent of the estimated 12 million refugees worldwide, are among the world's most vulnerable populations. They are subject to gender-based violence, including physical harm, rape, and unequal access to humanitarian assistance. GAO was asked to (1) assess efforts by the U.N. High Commissioner for Refugees (UNHCR) to protect refugees, especially with regard to women and girls; (2) determine what steps U.N. and international organizations have taken to prevent sexual exploitation of refugee women by humanitarian workers; and (3) describe U.S. government efforts to support adequate protection for vulnerable populations."

A letter report issued by the General Accounting Office with an abstract that begins "Under the Transportation Equity Act for the 21 st Century (TEA-21), Congress authorized federal funding for New Starts fixed guideway transit projects--including rail and bus rapid transit projects that met certain criteria. In response to an annual mandate under TEA-21, GAO assessed the New Starts evaluation and ratings process for the fiscal year 2004 cycle, including (1) changes to the process and any related issues and (2) any challenges related to New Starts initiatives contained in the administration's fiscal year 2004 budget proposal."

A letter report issued by the General Accounting Office with an abstract that begins "Because of concerns that not enough students who start college are completing a bachelor's degree, we examined (1) the extent to which students who enroll in a 4-year college complete a bachelor's degree and identify the factors that affect completion; (2) what states and 4-year colleges and universities are doing to foster bachelor's degree completion; and (3) what the Department of Education (Education) is doing to foster degree completion."

A letter report issued by the General Accounting Office with an abstract that begins "Over the past decade, a series of devastating and deadly wildland fires has burned millions of acres of federal forests, grasslands, and deserts each year, requiring federal land management agencies to spend hundreds of millions of dollars to fight them. GAO was asked to assess opportunities to improve the way agencies manage fires through the use of geospatial information technologies, specifically, to (1) identify key geospatial information technologies for addressing different aspects of managing wildland fires, (2) summarize key challenges to the effective use of geospatial technologies in managing wildland fires, and (3) identify national opportunities to improve the effective use of geospatial technologies."

A letter report issued by the General Accounting Office with an abstract that begins "The federal government has a long-term commitment to helping states construct, improve, and repair roads and bridges to meet the nation's mobility needs. The Federal Highway Administration (FHWA) expects to provide states about $20 billion for highway construction projects in fiscal year 2003. State departments of transportation are primarily responsible for initiating and completing projects. Many federal and state agencies with environmental responsibilities (called resource agencies) help ensure that environmental issues are considered. The environmental review of a federally funded highway project can take from several days to several years. GAO is reporting on the (1) activities involved in the environmental reviews of federally funded highway projects and (2) stakeholders' views on the aspects of environmental review, if any, that unduly add time to gaining environmental approval. GAO obtained stakeholder views from 16 transportation improvement and 12 environmental officials from a variety of federal, state, and private organizations with responsibilities for or interests in constructing federally funded highways. The Department of Transportation had no comments on a draft of this report. Other agencies provided either technical comments or did not respond to our request for comments."

A chapter report issued by the General Accounting Office with an abstract that begins "Coordination of federal programs to combat terrorism overseas became even more critical as a result of the terrorist attacks against the United States on September 11, 2001. In response to these attacks, the federal government has taken unprecedented political, diplomatic, legal, law enforcement, financial, military, and intelligence actions to combat terrorism abroad. Among these actions is the publication of a series of new national strategies to combat terrorism. Congress asked that we develop baseline information identifying and describing federal programs and activities to combat terrorism overseas. This report describes the interagency framework and policies for planning and coordinating federal efforts to counter international terrorism. It identifies the relationships between and among the new national strategies to combat terrorism. It also describes the federal programs and activities governmentwide to detect and prevent terrorism, disrupt and destroy terrorist organizations, and respond to terrorist incidents overseas. Finally, it provides detailed matrices of selected departments' programs and activities to combat terrorism overseas. We briefed Congress previously on the preliminary results of our work and issued an interim report on Combating Terrorism: Department of State Programs to Combat Terrorism Abroad. This …

A letter report issued by the General Accounting Office with an abstract that begins "The Thrift Savings Plan (TSP) is a retirement savings and investment plan for federal employees, governed by the Federal Retirement Thrift Investment Board (the TSP Board). Recent events relating to the TSP Board's contract to upgrade TSP's record keeping system have raised questions about the management of the TSP. In light of the TSP Board's actions relating to the record keeping system and the recent submission of the TSP Board's legislative proposal that would enhance its independence, Congressional requesters asked us to examine federal oversight of the TSP Board. Specifically, our objectives were to (1) describe the Department of Labor's (DOL) oversight authority, under the Federal Employees' Retirement System Act of 1986 (FERSA) and (2) determine the actions DOL has taken in exercising its authority over TSP."

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense's Missile Defense Agency (MDA) is developing a ballistic missile defense system designed to counter a wide spectrum of ballistic missile threats. A future element of this system is the Space Tracking and Surveillance System (STSS). STSS will eventually be composed of a constellation of satellites that will work together to detect and track missiles throughout all phases of their flight. GAO was asked to analyze MDA's approach to demonstrate capabilities for STSS."

A letter report issued by the General Accounting Office with an abstract that begins "In 1992, the United States and other parties, including both developed and developing nations, agreed to try to limit dangerous human interference with the climate by participating in the United Nations Framework Convention on Climate Change. The parties agreed, among other things, to report on their emissions of carbon dioxide and five other gases whose buildup in the atmosphere is believed to affect the climate. The parties developed standards for these reports and processes for periodically evaluating the reports. Expert teams selected by the parties review the developed nations' reports; staff of the Framework Convention's administrative arm (the Secretariat) assess developing nations' reports. GAO agreed to describe the results of the most recent reviews and assessments of reports from selected economically developed and developing nations, as well as the parties' plans to improve the reports. For the developed nations, GAO agreed to study four geographically dispersed nations with high levels of emissions--Germany, Japan, the United Kingdom, and the United States. For the developing nations, GAO studied China, India, and Mexico, which also have high emissions levels and are geographically dispersed. These nations are not representative of …

Silica membranes were prepared using a novel technique of catalyzed-atomic layer deposition of silica within a mesoporous matrix. Pyridine was used to catalyze the silicon chloride attachment to the hydroxylated silica surface at room temperature. This half-reaction was followed by the hydration of the surface with water regenerating surface hydroxyls and completing one reaction cycle. The technique resulted in the self-limited pore size reduction of the mesoporous matrix to pore sizes near 1 nm. The self-limited reaction was presumed to be the exclusion of the large catalyst molecule from the pore entrance. In addition to pore size reduction, viscous flow defects were repaired without significantly reducing overall porosity of the membrane. In addition, we investigated the ability of amine-functionalization to enhance the CO{sub 2} transport in silica membranes. Specifically, we examined three synthesis techniques for functionalizing silica membranes with amino groups that resulted in different surface chemistries of the silica membranes. These differences were correlated with changes in the CO{sub 2} facilitation characteristics. It was found that high loadings of amino groups where interaction with the silica surface was minimized promoted the highest CO{sub 2} transport.

The objective of the research was to perform a comprehensive computational analysis of the effects of material and process modeling approaches on performance of UltraLight Steel Auto Body (ULSAB) vehicle models. The research addressed numerous material related effects, impact conditions as well as analyzed the performance of the ULSAB vehicles in crashes against designs representing the current US vehicle fleet. This report is organized into three main sections. The first section describes the results of the computational analysis of ULSAB crash simulations that were performed using advanced material modeling techniques. The effects of strain-rate sensitivity on a high strength steel (HSS) intensive vehicle were analyzed. Frontal and frontal offset crash scenarios were used in a finite element parametric study of the ULSAB body structure. Comparisons are made between the crash results using the piece-wise-linear isotropic plasticity strain-rate dependent material model, and the isotropic plasticity material model based on quasi-static properties. The simulation results show the importance of advanced material modeling techniques for vehicle crash simulations due to strain-rate sensitivity and rapid hardening characteristics of advanced high strength steels. Material substitution was investigated for the main frontal crush structure using the material of similar yield stress a significantly different strain-rate and …

A 3-dimensional coal structural model for the Argonne Premium Coal Pocahontas No. 3 has been generated. The model was constructed based on the wealth of structural information available in the literature with the enhancement that the structural diversity within the structure was represented implicitly (for the first time) based on image analysis of HRTEM in combination with LDMS data. The complex and large structural model (>10,000 carbon atoms) will serve as a basis for examining the interaction of gases within this low volatile bituminous coal. Simulations are of interest to permit reasonable simulations of the host-guest interactions with regard to carbon dioxide sequestration within coal and methane displacement from coal. The molecular structure will also prove useful in examining other coal related behavior such as solvent swelling, liquefaction and other properties. Molecular models of CO{sub 2} have been evaluated with water to analyze which classical molecular force-field parameters are the most reasonable to predict the interactions of CO{sub 2} with water. The comparison of the molecular force field models was for a single CO{sub 2}-H{sub 2}O complex and was compared against first principles quantum mechanical calculations. The interaction energies and the electrostatic interaction distances were used as criteria in the …

This report is the second of a series of studies to evaluate research and development (R&D) projects funded by the Automotive Lightweighting Materials (ALM) Program of the Office of Advanced Automotive Technologies (OAAT) of the U.S. Department of Energy (DOE). The objectives of the program evaluation are to assess short-run outputs and long-run outcomes that may be attributable to the ALM R&D projects. The ALM program focuses on the development and validation of advanced technologies that significantly reduce automotive vehicle body and chassis weight without compromising other attributes such as safety, performance, recyclability, and cost. Funded projects range from fundamental materials science research to applied research in production environments.

The primary legal issues concern: 1) the ability of working mothers to breastfeed their children and/or to express milk during working hours; and 2) the nursing and/or expression of milk in public or semi-public places such as restaurants, public transportation facilities, and other locations where the public is present.

The Commodity Credit Corporation (CCC) of the U.S. Department of Agriculture (USDA) has entered into an interagency agreement with the U.S. Department of Energy (DOE) under which Argonne National Laboratory provides technical assistance for hazardous waste site characterization and remediation for the CCC/USDA. Carbon tetrachloride is the contaminant of primary concern at sites in Kansas where former CCC/USDA grain storage facilities were located. Argonne applies its QuickSite(reg sign) Expedited Site Characterization (ESC) approach to these former facilities. The QuickSite environmental site characterization methodology is Argonne's proprietary implementation of the ESC process (ASTM 1998). Argonne has used this approach at several former CCC/USDA facilities in Kansas, including Agenda, Agra, Everest, and Frankfort. The Argonne ESC approach revolves around a multidisciplinary, team-oriented approach to problem solving. The basic features and steps of the QuickSite methodology are as follows: (1) A team of scientists with diverse expertise and strong field experience is required to make the process work. The Argonne team is composed of geologists, geochemists, geophysicists, hydrogeologists, chemists, biologists, engineers, computer scientists, health and safety personnel, and regulatory staff, as well as technical support staff. Most of the staff scientists are at the Ph.D. level; each has on average, more than 15 …
