"Advancing the state of aviation safety is a central mission of the National Aeronautics and Space Administration (NASA). Congress requested this review of NASA's aviation safety-related research programs, seeking an assessment of whether the programs have well-defined, prioritized, and appropriate research objectives; whether resources have been allocated appropriately among these objectives; whether the programs are well coordinated with the safety research programs of the Federal Aviation Administration; and whether suitable mechanisms are in place for transitioning the research results into operational technologies and procedures and certification activities in a timely manner. Advancing Aeronautical Safety contains findings and recommendations with respect to each of the main aspects of the review sought by Congress. These findings indicate that NASA's aeronautics research enterprise has made, and continues to make, valuable contributions to aviation system safety but it is falling short and needs improvement in some key respects."--Publisher's description.

The potential for fatigue to negatively affect human performance is well established. Concern about this potential in the aviation context extends back decades, with both airlines and pilots agreeing that fatigue is a safety concern. A more recent consideration is whether and how pilot commuting, conducted in a pilot's off-duty time, may affect fatigue. The National Academy of Sciences was asked to review available information related to the prevalence and characteristics of pilot commuting; sleep, fatigue, and circadian rhythms; airline and regulatory oversight policies; and pilot and airline practices. This interim report summarizes the committee's review to date of the available information. The final report will present a final review, along with the committee's conclusions and recommendations based on the information available during its deliberations.

Nearly everyone experiences fatigue, but some professions--such as aviation, medicine and the military--demand alert, precise, rapid, and well-informed decision making and communication with little margin for error. The potential for fatigue to negatively affect human performance is well established. Concern about this potential in the aviation context extends back decades, with both airlines and pilots agreeing that fatigue is a safety concern. A more recent consideration is whether and how pilot commuting, conducted in a pilot's off-duty time, may affect fatigue during flight duty. In summer 2010 the U.S. Congress directed the Federal Aviation Administration (FAA) to update the federal regulations that govern pilot flight and duty time, taking into account recent research related to sleep and fatigue. As part of their directive, Congress also instructed FAA to have the National Academy of Sciences conduct a study on the effects of commuting on pilot fatigue. The Effects of Commuting on Pilot Fatigue reviews research and other information related to the prevalence and characteristics of commuting; to the science of sleep, fatigue, and circadian rhythms; to airline and regulatory oversight policies; and to pilot and airline practices. The Effects of Commuting on Pilot Fatigue discusses the policy, economic, and regulatory issues that affect pilot commuting, and outlines potential next steps, including recommendations for regulatory or administrative actions, or further research by the FAA.

The U.S. Army Corps of Engineers recently completed its feasibility study for the Upper Mississippi River-Ilinois Waterway, which was one of the agency's longest and most complicated studies in its history. The first two reports from this WSTB committee reviewed analytical aspects of the Corps feasibility study. Water Resources Planning for the Upper Mississippi River and Illinois Waterway considers the broader issue of managing the multiple resources of the Upper Mississippi River and Illinois Waterway, especially with regard to several, recently-issued NRC reports on Corps of Engineers planning procedures. The report finds that a key issue regarding planning decisions on these river systems is the ambiguity related to several different pieces of legislation and acts that govern river management, and thus recommends that the administration and Congress clarify the federal intent for managing this river and waterway system. The report recommends an independent, retrospective reivew of the experience with a federal inter-agency Principals Group, which was convened to provide guidance to the Corps study. It is also recommended that the Corps strive to incorporate flexible, adaptive management principles through its entire water planning program, including operations of the lock and dam system.

For the past few years, the Corps has been working on what is known as the Restructured Upper Mississippi River-Illinois Waterway Feasibility Study, the heart of which is a multibillion-dollar proposal to double the length of up to a dozen locks on the river. The Research Council first reviewed the feasibility study in 2001 during controversies over the accuracy of models being used by the Corps to justify lock expansion based on increased demand for barge transportation. More than 100 million tons of cargo--half of it grain destined for international markets, the other half goods such as construction materials, coal, and chemicals--are shipped along the navigation system each year. The locks, which along with dams allow barges to traverse uneven river depths, were originally designed for "tows" of barges up to 600 feet long, but the length of a typical tow has increased, forcing the Corps to look for ways to relieve congestion. The book finds the U.S. Army Corps of Engineers has made good progress in broadening its proposed plan for navigation improvements on the Upper Mississippi River-Illinois Waterway system to give greater consideration to ecological restoration. However, the plan still does not provide sufficient economic justification for expanding locks on the rivers because of flaws in the models the Corps used to predict demand for barge transportation. Little attention is paid to inexpensive, nonstructural navigation improvements that could help better manage existing levels of barge traffic. The revised plan has been usefully expanded to include many creative and potentially useful ecosystem restoration measures. These measures, however, should be more firmly grounded in river science principles and more broadly consider ways the river's ecology might affect or be affected by navigation, recreation and other uses.

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.

The Bureau of Reclamation and Sandia National Laboratories jointly developed the Roadmap to serve as a strategic research pathway for desalination and water purification technologies to meet future water needs. The book recommends that the Roadmap include a sharper focus on the research and technological advancements needed to reach the long-term objectives. The book also suggests that the environmental, economic, and social costs of energy required by increased dependence on desalination be examined. Strategies for implementing the Roadmap initiative are provided.

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.

From 1962 to 1971, US military forces sprayed more than 19 million gallons of herbicides over Vietnam to strip the thick jungle canopy that helped conceal opposition forces, to destroy crops that enemy forces might depend on, and to clear tall grass and bushes from around the perimeters of US base camps and outlying fire-support bases. Most large-scale spraying operations were conducted from airplanes and helicopters, but herbicides were also sprayed from boats and ground vehicles, and by soldiers wearing back-mounted equipment. After a scientific report concluded that a contaminant of one of the primary chemicals used in the herbicide called Agent Orange could cause birth defects in laboratory animals, US forces suspended use of the herbicide; they subsequently halted all herbicide spraying in Vietnam in 1971. At the request of the Veteran's Administration, the Institute of Medicine established a committee to oversee the development and evaluation of models of herbicide exposure for use in studies of Vietnam veterans. That committee would develop and disseminate a request for proposals (RFP) consistent with the recommendations; evaluate the proposals received in response to the RFP and select one or more academic or other nongovernmental research groups to develop the exposure reconstruction model; provide scientific and administrative oversight of the work of the researchers; and evaluate the models developed by the researchers in a report to VA, which would be published for a broader audience. Characterizing Exposure of Veterans to Agent Orange and Other Herbicides Used in Vietnam is the IOM's report that evaluates models of herbicide reconstruction to develop and test models of herbicide exposure for use in studies of Vietnam veterans.

The report evaluates a White Paper written by restoration planners in South Florida on the role of water flow in restoration plans. The report concludes that there is strong evidence that the velocity, rate, and spatial distribution of water flow play important roles in maintaining the tree islands and other ecologically important landscape features of the Everglades.

Assessment in Support of Instruction and Learning is the summary of a National Research Council workshop convened to examine the gap between external and classroom assessment. This report discusses issues associated with designing an assessment system that meets the demands of public accountability and, at the same time, improves the quality of the education that students receive day by day. This report focuses on assessment that addresses both accountability and learning.

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.

Recognizing the important contributions that genomic analysis can make to agriculture, production and companion animal science, evolutionary biology, and human health with respect to the creation of models for genetic disorders, the National Academies convened a group of individuals to plan a public workshop that would: (1) assess these contributions; (2) identify potential research directions for existing genomics programs; and (3) highlight the opportunities of a coordinated, multi-species genomics effort for the science and policymaking communities. Their efforts culminated in a workshop sponsored by the U.S. Department of Agriculture, Department of Energy, National Science Foundation, and the National Institutes of Health. The workshop was convened on February 19, 2002. The goal of the workshop was to focus on domestic animal genomics and its integration with other genomics and functional genomics projects.

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.

The federal courts are seeking ways to increase the ability of judges to deal with difficult issues of scientific expert testimony. The workshop explored the new environment judges, plaintiffs, defendants, and experts face in light of "Daubert" and "Kumho," when presenting and evaluating scientific, engineering, and medical evidence.

"The Centers for Disease Control and Prevention (CDC) established the Strategic National Stockpile (SNS) with a focus on procuring and managing medical countermeasures (MCM) designed to address chemical, biological, radiological, and nuclear events and attacks by weapons of mass destruction. The stockpile is a repository of antibiotics, chemical antidotes, antitoxins, vaccines, antiviral drugs, and other medical material organized to respond to a spectrum of public health threats. Over time, the mission of the SNS has informally evolved to address other large-scale catastrophes, such as hurricanes or outbreaks of pandemic disease, and rare acute events, such as earthquakes or terror attacks. When disaster strikes, states can request deployment of SNS assets to augment resources available to state, local, tribal, or territorial public health agencies. CDC works with federal, state, and local health officials to identify and address their specific needs and, according to the stated mission of the SNS, ensure that the right resources reach the right place at the right time"--

"Openness and sharing of information are fundamental to the progress of science and to the effective functioning of the research enterprise. The advent of scientific journals in the 17th century helped power the Scientific Revolution by allowing researchers to communicate across time and space, using the technologies of that era to generate reliable knowledge more quickly and efficiently. Harnessing today's stunning, ongoing advances in information technologies, the global research enterprise and its stakeholders are moving toward a new open science ecosystem. Open science aims to ensure the free availability and usability of scholarly publications, the data that result from scholarly research, and the methodologies, including code or algorithms, that were used to generate those data. Open Science by Design is aimed at overcoming barriers and moving toward open science as the default approach across the research enterprise. This report explores specific examples of open science and discusses a range of challenges, focusing on stakeholder perspectives. It is meant to provide guidance to the research enterprise and its stakeholders as they build strategies for achieving open science and take the next steps"--

"The question of whether and under what circumstances terminally ill patients should be able to access life-ending medications with the aid of a physician is receiving increasing attention as a matter of public opinion and of public policy. Ethicists, clinicians, patients, and their families debate whether physician-assisted death ought to be a legal option for patients. While public opinion is divided and public policy debates include moral, ethical, and policy considerations, a demand for physician-assisted death persists among some patients, and the inconsistent legal terrain leaves a number of questions and challenges for health care providers to navigate when presented with patients considering or requesting physician-assisted death. To discuss what is known and not known empirically about the practice of physician-assisted death, the National Academies of Sciences, Engineering, and Medicine convened a 2-day workshop in Washington, DC, on February 12-13, 2018. This publication summarizes the presentations and discussions from the workshop"--Publisher's description.

Beginning in October 2017, the National Academies of Sciences, Engineering, and Medicine organized a set of workshops designed to gather information for the Decadal Survey of Social and Behavioral Sciences for Applications to National Security.

Since the end of the Second World War, the United States has developed the world's preeminent system for biomedical research, one that has given rise to revolutionary medical advances as well as a dynamic and innovative business sector generating high-quality jobs and powering economic output and exports for the U.S. economy. However, there is a growing concern that the biomedical research enterprise is beset by several core challenges that undercut its vitality, promise, and productivity and that could diminish its critical role in the nation's health and innovation in the biomedical industry. Among the most salient of these challenges is the gulf between the burgeoning number of scientists qualified to participate in this system as academic researchers and the elusive opportunities to establish long-term research careers in academia. The patchwork of measures to address the challenges facing young scientists that has emerged over the years has allowed the U.S. biomedical enterprise to continue to make significant scientific and medical advances. These measures, however, have not resolved the structural vulnerabilities in the system, and in some cases come at a great opportunity cost for young scientists. These unresolved issues could diminish the nation's ability to recruit the best minds from all sectors of the U.S. population to careers in biomedical research and raise concerns about a system that may favor increasingly conservative research proposals over high-risk, innovative ideas. The Next Generation of Biomedical and Behavioral Sciences Researchers: Breaking Through evaluates the factors that influence transitions into independent research careers in the biomedical and behavioral sciences and offers recommendations to improve those transitions. These recommendations chart a path to a biomedical research enterprise that is competitive, rigorous, fair, dynamic, and can attract the best minds from across the country.

"On September 14, 2017, the Roundtable on Population Health Improvement of the National Academies of Sciences, Engineering, and Medicine convened a workshop to explore the intersection of health and early childhood care and education, two key social determinants of health. This workshop follows a 2014 roundtable workshop that considered the interface between the education and health sectors broadly, from research and metrics to cross-sectoral partnerships and financing. The 2017 workshop continued that discussion, with a deeper focus on early childhood (birth through age 5) as a critical period in human development and an important opportunity for educational and related interventions. This publication summarizes the presentations and discussions from the 2017 workshop"--Publisher's description.

"Black men are increasingly underrepresented in medical schools and in the medical profession. A diverse workforce is a key attribute of quality healthcare and research suggests that a diverse workforce may help to advance cultural competency and increase access to high-quality health care, especially for underserved populations. Conversely, lack of diversity in the health workforce threatens health care quality and access and contributes to health disparities. In this way, the growing absence of Black men in medicine is especially troubling, because their absence in medicine may have adverse consequences for health care access, quality, and outcomes among Black Americans and Americans overall. To better understand the factors that contribute to the low participation of Black men in the medical profession, facilitate discussion of current strategies used to increase their participation in medical education, and explore new strategies along the educational and professional pipeline that may have potential to increase participation in medicine, the National Academies of Sciences, Engineering, and Medicine and the Cobb Institute jointly convened a 2-day workshop in November 2017, in Washington, DC. This publication summarizes the presentations and discussions from the workshop"--

"The increasing diversity of population of the United States presents many challenges to conducting health research that is representative and informative. Dispersion and accessibility issues can increase logistical costs; populations for which it is difficult to obtain adequate sample size are also likely to be expensive to study. Hence, even if it is technically feasible to study a small population, it may not be easy to obtain the funding to do so. In order to address the issues associated with improving health research of small populations, the National Academies of Sciences, Engineering, and Medicine convened a workshop in January 2018. Participants considered ways of addressing the challenges of conducting epidemiological studies or intervention research with small population groups, including alternative study designs, innovative methodologies for data collection, and innovative statistical techniques for analysis"--Publisher's description.
