Workload transition is a potentially crucial problem in work situations wherein operators are faced with abrupt changes in task demands. People involved include military combat personnel, air-traffic controllers, medical personnel in emergency rooms, and long-distance drivers. They must be able to respond efficiently to sudden increases in workload imposed by a failure, crisis, or other, often unexpected, event. This book provides a systematic evaluation of workload transition. It focuses on a broad spectrum of activities ranging from team cooperation to the maintenance of this problem on a theoretical level and offers several practical solutions.
Serving as a companion to Growing Up Global, this book from the National Research Council explores how the transition to adulthood is changing in developing countries in light of globalization and what the implications of these changes might be for those responsible for designing youth policies and programs. Presenting a detailed series of studies, this volume both complements its precursor and makes for a useful contribution in its own right. It should be of significant interest to scholars, leaders of civil society, and those charged with designing youth policies and programs.
Despite the strong safety record of the national airspace system, serious disruptions occasionally occur, often as a result of outdated or failed equipment. Under these circumstances, safety relies on the skills of the controllers and pilots and on reducing the number of aircraft in the air. The current and growing pressures to increase the capacity to handle a greater number of flights has led to a call for faster and more powerful equipment and for equipment that can take over some of the tasks now being performed by humans. Increasing the role of automation in air traffic control may provide a more efficient system, but will human controllers be able to effectively take over when problems occur? This comprehensive volume provides a baseline of knowledge about the capabilities and limitations of humans relative to the variety of functions performed in air traffic control. It focuses on balancing safety with the expeditious flow of air traffic, identifying lessons from past air accidents. The book discusses: The function of the national airspace system and the procedures for hiring, training, and evaluating controllers. Decisionmaking, memory, alertness, vigilance, sleep patterns during shift work, communication, and other factors in controllers' performance. Research on automation and human factors in air traffic control and incorporation of findings into the system. The Federal Aviation Administration's management of the air traffic control system and its dual mandate to promote safety and the development of air commerce. This book also offers recommendations for evaluation the human role in automated air traffic control systems and for managing the introduction of automation into current facilities and operations. It will be of interest to anyone concerned about air safetyâ€"policymakers, regulators, air traffic managers and controllers, airline officials, and passenger advocates.
Automation in air traffic control may increase efficiency, but it also raises questions about adequate human control over automated systems. Following on the panel's first volume on air traffic control automation, Flight to the Future (NRC, 1997), this book focuses on the interaction of pilots and air traffic controllers, with a growing network of automated functions in the airspace system. The panel offers recommendations for development of human-centered automation, addressing key areas such as providing levels of automation that are appropriate to levels of risk, examining procedures for recovery from emergencies, free flight versus ground-based authority, and more. The book explores ways in which technology can build on human strengths and compensate for human vulnerabilities, minimizing both mistrust of automation and complacency about its abilities. The panel presents an overview of emerging technologies and trends toward automation within the national airspace systemâ€"in areas such as global positioning and other aspects of surveillance, flight information provided to pilots an controllers, collision avoidance, strategic long-term planning, and systems for training and maintenance. The book examines how to achieve better integration of research and development, including the importance of user involvement in air traffic control. It also discusses how to harmonize the wide range of functions in the national airspace system, with a detailed review of the free flight initiative.
Simulations are widely used in the military for training personnel, analyzing proposed equipment, and rehearsing missions, and these simulations need realistic models of human behavior. This book draws together a wide variety of theoretical and applied research in human behavior modeling that can be considered for use in those simulations. It covers behavior at the individual, unit, and command level. At the individual soldier level, the topics covered include attention, learning, memory, decisionmaking, perception, situation awareness, and planning. At the unit level, the focus is on command and control. The book provides short-, medium-, and long-term goals for research and development of more realistic models of human behavior.
This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.
At least 7 million young Americansâ€"fully one-quarter of adolescents 10 to 17 years oldâ€"may be at risk of failing to achieve productive adult lives. They use drugs, engage in unprotected sex, drop out of school, and sometimes commit crimes, effectively closing the door to their own futures. And the costs to society are enormous: school and social services are overwhelmed, and our nation faces the future with a diminished citizenry. This penetrating book argues that the problems of troubled youth cannot be separated from the settings in which those youths liveâ€"settings that have deteriorated significantly in the past two decades. A distinguished panel examines what works and what does not in the effort to support and nurture adolescents and offers models for successful programs. This volume presents an eye-opening look at what millions of the nation's youths confront every day of their lives, addressing: How the decline in economic security for young working parents affects their children's life chances. How dramatic changes in household structure and the possibilities of family and community violence threaten adolescents' development. How the decline of neighborhoods robs children of a safe environment. How adolescents' health needs go unmet in the current system. Losing Generations turns the spotlight on those institutions youths needâ€"the health care system, schools, the criminal justice, and the child welfare and foster home systemsâ€"and how they are functioning. Difficult issues are addressed with study results and insightful analyses: access of poor youths to health insurance coverage, inequities in school funding, how child welfare agencies provide for adolescents in their care, and the high percentage of young black men in the criminal justice system.
The challenges for young people making the transition to adulthood are greater today than ever before. Globalization, with its power to reach across national boundaries and into the smallest communities, carries with it the transformative power of new markets and new technology. At the same time, globalization brings with it new ideas and lifestyles that can conflict with traditional norms and values. And while the economic benefits are potentially enormous, the actual course of globalization has not been without its critics who charge that, to date, the gains have been very unevenly distributed, generating a new set of problems associated with rising inequality and social polarization. Regardless of how the globalization debate is resolved, it is clear that as broad global forces transform the world in which the next generation will live and work, the choices that today's young people make or others make on their behalf will facilitate or constrain their success as adults. Traditional expectations regarding future employment prospects and life experiences are no longer valid. Growing Up Global examines how the transition to adulthood is changing in developing countries, and what the implications of these changes might be for those responsible for designing youth policies and programs, in particular, those affecting adolescent reproductive health. The report sets forth a framework that identifies criteria for successful transitions in the context of contemporary global changes for five key adult roles: adult worker, citizen and community participant, spouse, parent, and household manager.
Subjective well-being refers to how people experience and evaluate their lives and specific domains and activities in their lives. This information has already proven valuable to researchers, who have produced insights about the emotional states and experiences of people belonging to different groups, engaged in different activities, at different points in the life course, and involved in different family and community structures. Research has also revealed relationships between people's self-reported, subjectively assessed states and their behavior and decisions. Research on subjective well-being has been ongoing for decades, providing new information about the human condition. During the past decade, interest in the topic among policy makers, national statistical offices, academic researchers, the media, and the public has increased markedly because of its potential for shedding light on the economic, social, and health conditions of populations and for informing policy decisions across these domains. Subjective Well-Being: Measuring Happiness, Suffering, and Other Dimensions of Experience explores the use of this measure in population surveys. This report reviews the current state of research and evaluates methods for the measurement. In this report, a range of potential experienced well-being data applications are cited, from cost-benefit studies of health care delivery to commuting and transportation planning, environmental valuation, and outdoor recreation resource monitoring, and even to assessment of end-of-life treatment options. Subjective Well-Being finds that, whether used to assess the consequence of people's situations and policies that might affect them or to explore determinants of outcomes, contextual and covariate data are needed alongside the subjective well-being measures. This report offers guidance about adopting subjective well-being measures in official government surveys to inform social and economic policies and considers whether research has advanced to a point which warrants the federal government collecting data that allow aspects of the population's subjective well-being to be tracked and associated with changing conditions.
