    The chemical sector is a key part of the national economy and has been designated by the Department of Homeland Security (DHS) as one of 17 sectors comprising the nation's Critical Infrastructure. Although its products represent only 2 percent of the U.S. gross domestic product, those products underpin most other manufactured goods. To assist DHS in characterizing and mitigating the vulnerabilities faced by the nation from the chemical industry, this study examines classes of chemicals and chemical processes that are critical to the nation's security, economy, and health. It identifies vulnerabilities and points of weakness in the supply chain for these chemicals and chemical processes; assesses the likely impact of a significant disruption in the supply chain; identifies actions to help prevent disruption in the supply chain and mitigate loss and injury should such disruption occur; identifies incentives and disincentives to preventative and mitigating actions; and recommends areas of scientific, engineering, and economic research and development. The report concludes that the consequences of a deliberate attack on the chemical infrastructure would be expected to be similar in nature to the accidents we have already experienced. Under limited circumstances, such an attack could cause catastrophic casualties and loss of life, but it would take several simultaneous events to cause catastrophic economic consequences. Poor communication could amplify societal response. Overall, the recommendations in this report emphasize the benefit of investments to improve emergency preparedness for and response to chemical events. They also highlight the potential to minimize the physical hazards through development of cost-effective, safer processes that reduce the volume, toxicity, or hazardous conditions under which chemicals are processed.

    The U.S. Army Corps of Engineers has a long history of managing navigation, floods, and other water-related issues on the Upper Mississippi and Illinois Rivers. A recent chapter in that history is the problem of waterway congestion at several locks on the lower portion of the Upper Mississippi River. The Corps has studied this problem and its possible solutions since the late 1980s, producing a draft feasibility study in 2000 and an interim report on a restructured feasibility study in 2002. A committee was convened to review and provide advice on the most recent phase of the Corps' analytical efforts.

    As recently as the summer of 2001, many travelers were dreading air transportation because of extensive delays associated with undercapacity of the system. That all changed on 9/11, and demand for air transportation has not yet returned to peak levels. Most U.S. airlines continue to struggle for survival, and some have filed for bankruptcy. The situation makes it difficult to argue that strong action is urgently needed to avert a crisis of undercapacity in the air transportation system. This report assesses the visions and goals for U.S. civil aviation and technology goals for the year 2050.

    Progress in information technology (IT) has been remarkable, but the best truly is yet to come: the power of IT as a human enabler is just beginning to be realized. Whether the nation builds on this momentum or plateaus prematurely depends on today's decisions about fundamental research in computer science (CS) and the related fields behind IT. The Computer Science and Telecommunications Board (CSTB) has often been asked to examine how innovation occurs in IT, what the most promising research directions are, and what impacts such innovation might have on society. Consistent themes emerge from CSTB studies, notwithstanding changes in information technology itself, in the IT-producing sector, and in the U.S. university system, a key player in IT research. In this synthesis report, based largely on the eight CSTB reports enumerated below, CSTB highlights these themes and updates some of the data that support them.

    Recent rough estimates are that the U.S. Department of Defense (DoD) spends at least $38 billion a year on the research, development, testing, and evaluation of new defense systems; approximately 40 percent of that cost-at least $16 billion-is spent on software development and testing. There is widespread understanding within DoD that the effectiveness of software-intensive defense systems is often hampered by low-quality software as well as increased costs and late delivery of software components. Given the costs involved, even relatively incremental improvements to the software development process for defense systems could represent a large savings in funds. And given the importance of producing defense software that will carry out its intended function, relatively small improvements to the quality of defense software systems would be extremely important to identify. DoD software engineers and test and evaluation officials may not be fully aware of a range of available techniques, because of both the recent development of these techniques and their origination from an orientation somewhat removed from software engineering, i.e., from a statistical perspective. The panel's charge therefore was to convene a workshop to identify statistical software engineering techniques that could have applicability to DoD systems in development.

    Over the past half century, the international flow of goods, services, and capital has grown rapidly. Globalization creates new economic, cultural, and social opportunities, but also poses the challenge of ensuring that workers throughout the world share in these opportunities. Responding to this challenge, the U.S. government carries out a variety of policies and programs aimed at encouraging greater recognition of worker rights around the globe. The U.S. Department of State monitors worker rights abroad and reports on the status of those rights as part of its annual report to Congress in the Country Reports on Human Rights Practices. Building on this history of monitoring and encouraging worker rights around the world, the Trade Act of 2002 includes on the list of overall trade negotiating objectives of the United States, promote respect for worker rights. Monitoring International Labor Standards provides expert, science-based advice on monitoring compliance with international labor standards. This report identifies relevant, valid, reliable, and useful sources of country-level data on labor standards; assesses the quality of existing and potential data and indicators that can be used to systematically monitor labor practices and the effectiveness of enforcement in order to determine compliance with national labor legislation and international standards; identifies innovative measures to determine compliance with international labor standards on a country-by-country basis and to measure progress on improved labor legislation and enforcement; explores the relationship between labor standards compliance and national policies relating to human capital issues; and recommends sustainable reporting procedures to monitor countries' progress toward implementation of international labor standards.

    The report provides an independent assessment of suitable test protocols that might be useful and reliable for the testing and evaluation of standoff chemical agent detectors. The report proposes two testing protocols, one for passive detectors and one for active detectors, to help ensure the reliable detection of a release of chemical warfare agents. The report determined that testing these detectors by release of chemical warfare agents into the atmosphere would not provide additional useful information on the effectiveness of these detectors than would a rigorous testing protocol using chemical agents in the laboratory combined with atmospheric release of simulated chemical warfare agents.

    Each new generation of commercial aircraft produces less noise and fewer emissions per passenger-kilometer (or ton-kilometer of cargo) than the previous generation. However, the demand for air transportation services grows so quickly that total aircraft noise and emissions continue to increase. Meanwhile, federal, state, and local noise and air quality standards in the United States and overseas have become more stringent. It is becoming more difficult to reconcile public demand for inexpensive, easily accessible air transportation services with concurrent desires to reduce noise, improve local air quality, and protect the global environment against climate change and depletion of stratospheric ozone. This situation calls for federal leadership and strong action from industry and government. U.S. government, industry, and universities conduct research and develop technology that could help reduce aircraft noise and emissions-but only if the results are used to improve operational systems or standards. For example, the (now terminated) Advanced Subsonic Technology Program of the National Aeronautics and Space Administration (NASA) generally brought new technology only to the point where a system, subsystem model, or prototype was demonstrated or could be validated in a relevant environment. Completing the maturation process-by fielding affordable, proven, commercially available systems for installation on new or modified aircraft-was left to industry and generally took place only if industry had an economic or regulatory incentive to make the necessary investment. In response to this situation, the Federal Aviation Administration, NASA, and the Environmental Protection Agency, asked the Aeronautics and Space Engineering Board of the National Research Council to recommend research strategies and approaches that would further efforts to mitigate the environmental effects (i.e., noise and emissions) of aviation. The statement of task required the Committee on Aeronautics Research and Technology for Environmental Compatibility to assess whether existing research policies and programs are likely to foster the technological improvements needed to ensure that environmental constraints do not become a significant barrier to growth of the aviation sector.

    Noteworthy progress has been made recently toward understanding and quantifying the smoke toxicity factors involved in fire hazard assessment. Such progress has led to increased attention to the significance of fire growth parameters for toxic hazard. Methodology has been proposed to use fire test data, including information on the toxic potency of smoke in engineering calculations for the assessment of overall fire hazard. Confidence in the methodology may evolve from comparison with full-scale fire tests as well as from human fire fatality experience. This report addresses fire modeling, fire testing, smoke toxicity testing, fire hazard assessment, and fire risk assessment. In the assessment of potential toxic hazards in the event of fires in mass transit vehicles, the report concludes that selection of candidate materials should be based on analyses using both toxicological and engineering considerations.

    The US Environmental Protection Agency Office of Radiation and Indoor Air asked the National Research Council to evaluate whether sufficient new data exist to warrant a reassessment of health risks reported in Health Effects of Exposure to Low Levels of Ionizing Radiations (BEIR V) in 1990. To respond to this request, the National Research Council assembled the Committee on Health Risks of Exposure to Low Levels of Ionizing Radiations. The work of the committee was conducted in what was called the BEIR VII phase-1 study. To assist the committee during its deliberations, various scientists were consulted for advice, and a workshop on the impact of biology on risk assessment was held in collaboration with the Department of Energy Office of Health and Environmental Research. The intent of the workshop was to address the implications of new understanding of the biologic basis of radiation injury and carcinogenesis for risk assessment.
