It has long been accepted that the social and cultural meanings of the car far exceed the practical need for mobility. This book marks the first attempt to contribute to road safety, considering, in depth, these meanings and the cultures of driving that are shaped by them. In the Company of Cars examines the perspectives that young people have on cars, and explores the broader social and cultural meanings of the car, the potential it is supposed to fulfil, and the anticipated benefits it offers to young drivers. From focus-group research conducted in Australia, the book takes up the views of young people on a range of topics, from media to car use to gender performance. The author looks at the ways in which driving has been defined by articulations of the car that emphasize valued features of the car-driver, such as gender, youthfulness, status, age, power, raciness, sexiness, ruggedness and competitiveness. The book takes a global perspective on mobility, considering the impact of cars and road safety policy on quality of life, and the value and significance of other modes of travel, in a range of countries.

Edited by Jussi Kantola, the founding faculty member of the world's first university Knowledge Service Engineering Department at Korea Advanced Institute of Science and Technology, and Waldemar Karwowski from the Department of Industrial Engineering and Management Systems at UCF, Knowledge Service Engineering Handbook defines what knowledge services engineering means and how it is different from service engineering and service production. This groundbreaking handbook explores recent advances in knowledge service engineering from the accomplished researchers and practitioners in this field from around the world and provides engineering, systemic, industry, and consumer use viewpoints to knowledge service systems and engineering paradigms. The handbook outlines how to acquire and utilize knowledge in the 21st century presenting multiple cultural aspects including US, European, and Asian perspectives. Organized into four parts, it begins with an introduction to the main concepts of knowledge services. It then explores data, information and knowledge based engineering methods and applications that can be used to develop knowledge services, followed by discussions of the importance of human networks in knowledge services. The handbook concludes with descriptions of high-performance knowledge service systems. This structure allows different uses: the information can be looked up as needed or read in the order presented. As with any new field, the excitement lies in seeing how to combine these advances in data, information, and human parts of knowledge services in the future. While most books on this subject concentrate on data, information, or knowledge, this handbook integrates coverage of all three, thus providing a complete examination of sustainable knowledge services. The handbook has been carefully designed to be of use to professionals who develop new knowledge services and related businesses, for academic researchers and lecturers to start new research projects, and for students studying knowledge services, knowledge service production, and knowledge service business.

Written by international contributors, Learning Curves: Theory, Models, and Applications first draws a learning map that shows where learning is involved within organizations, then examines how it can be sustained, perfected, and accelerated. The book reviews empirical findings in the literature in terms of different sources for learning and partial assessments of the steps that make up the actual learning process inside the learning curve. Traditionally, books on learning curves have focused either on cost accounting or production planning and control. In these books, the learning curve has been treated as a forecasting tool. This book synthesizes current research and presents a clear picture of organizational learning curves. It explores how organizations improve other measures of organizational performance including quality, inventory, and productivity, then looks inside the learning curve to determine the actual processes through which organizations learn.

Macrocognition Metrics and Scenarios: Design and Evaluation for Real-World Teams translates advances by scientific leaders in the relatively new area of macrocognition into a format that will support immediate use by members of the software testing and evaluation community for large-scale systems as well as trainers of real-world teams. Macrocognition is defined as how activity in real-world teams is adapted to the complex demands of a setting with high consequences for failure. The primary distinction between macrocognition and prior research is that the primary unit for measurement is a real-world team coordinating their activity, rather than individuals processing information, the predominant model for cognition for decades. This book provides an overview of the theoretical foundations of macrocognition, describes a set of exciting new macrocognitive metrics, and provides guidance on using the metrics in the context of different approaches to evaluation and measurement of real-world teams.

Meshless, or meshfree methods, which overcome many of the limitations of the finite element method, have achieved significant progress in numerical computations of a wide range of engineering problems. A comprehensive introduction to meshless methods, Meshless Methods and Their Numerical Properties gives complete mathematical formulations for the most important and classical methods, as well as several methods recently developed by the authors. This book also offers a rigorous mathematical treatment of their numerical properties-including consistency, convergence, stability, and adaptivity-to help you choose the method that is best suited for your needs. Get Guidance for Developing and Testing Meshless Methods Developing a broad framework to study the numerical computational characteristics of meshless methods, the book presents consistency, convergence, stability, and adaptive analyses to offer guidance for developing and testing a particular meshless method. The authors demonstrate the numerical properties by solving several differential equations, which offer a clearer understanding of the concepts. They also explain the difference between the finite element and meshless methods. Explore Engineering Applications of Meshless Methods The book examines how meshless methods can be used to solve complex engineering problems with lower computational cost, higher accuracy, easier construction of higher-order shape functions, and easier handling of large deformation and nonlinear problems. The numerical examples include engineering problems such as the CAD design of MEMS devices, nonlinear fluid-structure analysis of near-bed submarine pipelines, and two-dimensional multiphysics simulation of pH-sensitive hydrogels. Appendices supply useful template functions, flowcharts, and data structures to assist you in implementing meshless methods. Choose the Best Method for a Particular Problem Providing insight into the special features and intricacies of meshless methods, this is a valuable reference for anyone developing new high-performance numerical methods or working on the modelling and simulation of practical engineering problems. It guides you in comparing and verifying meshless methods so that you can more confidently select the best method to solve a particular problem.

This edited volume of original chapters brings together researchers from around the world who are exploring the facets of health care organization and delivery that are sometimes marginal to mainstream patient safety theories and methodologies but offer important insights into the socio-cultural and organizational context of patient safety. By examining these critical insights or perspectives and drawing upon theories and methodologies often neglected by mainstream safety researchers, this collection shows we can learn more about not only the barriers and drivers to implementing patient safety programmes, but also about the more fundamental issues that shape notions of safety, alternate strategies for enhancing safety, and the wider implications of the safety agenda on the future of health care delivery. In so doing, A Socio-cultural Perspective on Patient Safety challenges the taken-for-granted assumptions around fundamental philosophical and political issues upon which mainstream orthodoxy relies. The book draws upon a range of theoretical and empirical approaches from across the social sciences to investigate and question the patient safety movement. Each chapter takes as its focus and question a particular aspect of the patient safety reforms, from its policy context and theoretical foundations to its practical application and manifestation in clinical practice, whilst also considering the wider implications for the organization and delivery of health care services. Accordingly, the chapters each draw upon a distinct theoretical or methodological approach to critically explore specific dimensions of the patient safety agenda. Taken as a whole, the collection advances a strong, coherent argument that is much needed to counter some of the uncritical assumptions that need to be described and analyzed if patient safety is indeed to be achieved.

Traffic psychology is a rapidly expanding and broad field within applied psychology with a considerable volume of research activities and a growing network of academic strands of enquiry. The discipline primarily focuses on the behaviour of road users and the psychological processes underlying these behaviours, looking at issues such as cognition, distraction, fatigue, personality and social aspects, often delivering practical applications and educational interventions. Traffic psychology has been the focus of research for almost as long as the motor car has been in existence and was first recognised as a discipline in 1990 when the International Association of Applied Psychology formed Division 13: Traffic and Transportation Psychology. The benefits of understanding traffic psychology are being increasingly recognised by a whole host of organisations keen to improve road safety or minimise health and safety risks when travelling in vehicles. The objective of this volume is to describe and discuss recent advances in the study of traffic psychology, with a major focus on how the field contributes to the understanding of at-risk road-user behaviour. The intended readerships include road-safety researchers from a variety of different academic backgrounds, senior practitioners in the field including regulatory authorities, the private and public sector personnel, and vehicle manufacturers concerned with improving road safety.

Assessing Command and Control Effectiveness: Dealing with a Changing World offers a description of the current state of Command and Control (C2) research in imperfect settings, showing how a research process should assess, analyse and communicate results to the development cycle of methods, work, manning and C2-technology. Special attention is given to the development of C2 research methods to meet the current and coming needs. The authors also look forward towards a future where effective assessment of C2 abilities are even more crucial, for instance in agile organisations. The purpose of the C2 research is to improve the process and make it more effective while still saving time and money. Research methods have to be chosen carefully to be effective and simple, yet provide results of high quality. The methodological concerns are a major consideration when working under such circumstances. Furthermore, there is often a need for a swift iterative development cycle, and thus a demand to quickly deliver results from the research process. This book explains how field research experimentation can be quick, simple and effective, being able to draw valid conclusions even when sample sizes are small and resources are limited, collecting empirical data using measures and procedures that are minimally intrusive.

In the real world the dynamic behavior of a real machine presents either unforeseen or limiting phenomena: both are undesired, and can be therefore be classified as parasitic phenomena - unwanted, unforeseen, or limiting behaviors. Parasitic Phenomena in the Dynamics of Industrial Devices describes the potential causes and effects of these behaviors and provides indications that could minimize their influence on the mechanical system in question. The authors introduce the phenomena and explore them through real cases, avoiding academic introductions, but inserting the entire academic and experimental knowledge that is useful to understand and solve real-world problems. They then examine these parasitic phenomena in the machine dynamics, using two cases that cover the classical cultural division between cam devices and mechanisms. They also present concrete cases with an amount of experimental data higher than the proposed ones and with a modern approach that can be applied to various mechanical devices, acquiring real knowledge superior to one of the mere finite element systems or collections of mechanical devices. Organizes machine dynamics through systems theory to give a comprehensive vision of the design problem Details machine dynamics at an advanced mathematics level and avoids redundancy of fundamental knowledge Introduces real machine cases for solutions to practical problems Covers two broad classes of mechanical devices that are widely used in the construction of instrumental goods Employs a mechatronic approach that can be applied to electro-mechanical, hydro-mechanical, or pneumo-mechanical machines Highlighting industrial devices in the manufacturing industry, including industrial indexing devices and industrial robots, the book offers case studies, advanced models, design methods, and short examples of applications. It is of critical importance for any manufacturing enterprise that produces significant amounts of objects through a process with one or more automated phases.

Fratricide has been defined as firing on your own forces, when mistaking them for enemy forces, which results in injury or death. Rates of fratricide incidence have been steadily increasing and the complexity of the contemporary operating environment may lead to a continuation of this trend. Although the majority of research into fratricide has focused on the development of technological decision aids, recent explorations highlight the need to emphasise the social aspects within a socio-technical framework. This book presents and validates, via the use of case studies, a model of teamwork and decision-making factors that are associated with incidents of fratricide. In summary, it offers a review and evaluation of contemporary theoretical perspectives on teamwork and fratricide, as well as a range of accident analysis approaches. A novel theory of fratricide is then presented followed by a new methodology for assessing fratricide. Naturalistic case studies of teams are undertaken in the military domain. These studies illustrate the approach and offer early validation evidence. In closing, the book presents a series of principles designed to reduce the likelihood of fratricide in the future.

Driver inattention has been identified as one of the leading causes for car accidents. The problem of distraction while driving is likely to worsen, partly due to increasingly complex in-car technologies. However, intelligent transport systems are being developed to assist drivers and to ensure a safe road environment. One approach to the design of ergonomic automobile systems is to integrate our understanding of the human information processing systems into the design process. This book aims to further the design of ergonomic multisensory interfaces using research from the fast-growing field of cognitive neuroscience. It focuses on two aspects of driver information-processing in particular: multisensory interactions and the spatial distribution of attention in driving. The Multisensory Driver provides interface design guidelines together with a detailed review of current cognitive neuroscience and behavioural research in multisensory human perception, which will help the development of ergonomic interfaces. The discussion on spatial attention is particularly relevant for car interface designers, but it will also appeal to cognitive psychologists interested in spatial attention and the applications of these theoretical research findings. Giving a detailed description of a cohesive series of psychophysical experiments on multisensory warning signals, conducted in both laboratory and simulator settings, this book provides an approach for those in the engineering discipline who wish to test their systems with human observers.

The development of new technologies of information and communication will, in the coming years, transform deeply their uses and practices in transport. The current developments in the field of road telematics and driver assistance systems offer a real opportunity to aid mobility and road safety. However, they also raise numerous questions about their effectiveness, possible positive and negative modifications of behaviour or attitudes and about their acceptability by drivers. Problems related to the design and evaluation of intelligent driver support systems (IDSSs) and social perspectives related to their introduction on a large scale may only be fully addressed from a multi-disciplinary point of view. People from different backgrounds, from both engineering and social sciences, should be involved in this development. This book provides such knowledge from both a human and social factors background. The Safety of Intelligent Driver Support Systems serves the training of professionals working within the transport area so that they can use this knowledge in their work. It will be of direct interest to transportation and traffic professionals, engineers, system designers, researchers and specialists working in automotive and related industries, departments of transport, and communication and public bodies related to transport in the automotive industry, public authorities, etc. Also students at Masters and PhD level, performing studies in the road transportation area, will find in this book a rich source of knowledge. Teachers and trainers, both in professional training and academic education, may use the book as a basis for giving a course on the topic addressed.

The consideration of human factors issues is vital to the mining industry. As in other safety-critical domains, human performance problems constitute a significant threat to system safety, making the study of human factors an important field for improving safety in mining operations. The primary purpose of this book is to provide the reader with a much-needed overview of human factors within the mining industry, in particular to understand the role of human error in mine safety, explaining contemporary risk management and safety systems approaches. The approach taken is multidisciplinary and holistic, based on a model of the systems of work in the mining industry domain. The ingredients in this model include individual operators, groups/teams, technology/equipment, work organisation and the physical environment. Throughout the book, topics such as human error and safety management are covered through the use of real examples and case studies, allowing the reader to see the practical significance of the material presented while making the text rigorous, useful and enjoyable. Understanding Human Error in Mine Safety is written for professionals in the field, researchers and students of mining engineering, safety or human factors.

Safety management and human factors disciplines are often regarded as subjective and nebulous. This perhaps stems from a variety of, sometimes disparate, activities in the realms of education, industry and research. Aviation is one of the safety-critical industries that has led the development of safety systems and human factors. However, in recent years, safety management and human factors are seen to be progressing well in the road, rail and the medical arena. Multimodal Safety Management and Human Factors is a wide-ranging compendium of contemporary approaches in the aviation, road, rail and medical domains. It brings together 28 chapters from both the academic and professional worlds that focus on applications, tools and strategies in safety management and human factors. It is a wellspring of the practical rather than the theoretical. Safety scientists, human factors industry practitioners, change management advocates, educators and students will find this book extremely relevant and challenging.

Military command and control is not merely evolving, it is co-evolving. Technology is creating new opportunities for different types of command and control, and new types of command and control are creating new aspirations for technology. The question is how to manage this process, how to achieve a jointly optimised blend of socio and technical and create the kind of agility and self-synchronisation that modern forms of command and control promise. The answer put forward in this book is to re-visit sociotechnical systems theory. In doing so, the problems of 21st century command and control can be approached from an alternative, multi-disciplinary and above all human-centred perspective. Human factors (HF) is also co-evolving. The traditional conception of the field is to serve as a conduit for knowledge between engineering and psychology yet 21st century command and control presents an altogether different challenge. Viewing military command and control through the lens of sociotechnical theory forces us to confront difficult questions about the non-linear nature of people and technology: technology is changing, from platform centric to network centric; the interaction with that technology is changing, from prescribed to exploratory; and complexity is increasing, from behaviour that is linear to that which is emergent. The various chapters look at this transition and draw out ways in which sociotechnical systems theory can help to understand it. The sociotechnical perspective reveals itself as part of a conceptual toolkit through which military command and control can be transitioned, from notions of bureaucratic, hierarchical ways of operating to the devolved, agile, self-synchronising behaviour promised by modern forms of command and control like Network Enabled Capability (NEC). Sociotechnical system theory brings with it a sixty year legacy of practical application and this real-world grounding in business process re-engineering underlies the entire book. An attempt has been made to bring a set of sometimes abstract (but no less useful) principles down to the level of easy examples, design principles, evaluation criteria and actionable models. All of these are based on an extensive review of the current state of the art, new sociotechnical/NEC studies conducted by the authors, and insights derived from field studies of real-life command and control. Time and again, what emerges is a realisation that the most agile, self-synchronising component of all in command and control settings is the human.

Many complex systems in civil and military operations are highly automated with the intention of supporting human performance in difficult cognitive tasks. The complex systems can involve teams or individuals working on real-time supervisory control, command or information management tasks where a number of constraints must be satisfied. Decision Making in Complex Environments addresses the role of the human, the technology and the processes in complex socio-technical and technological systems. The aim of the book is to apply a multi-disciplinary perspective to the examination of the human factors in complex decision making. It contains more than 30 contributions on key subjects such as military human factors, team decision making issues, situation awareness, and technology support. In addition to the major application area of military human factors there are chapters on business, medical, governmental and aeronautical decision making. The book provides a unique blend of expertise from psychology, human factors, industry, commercial environments, the military, computer science, organizational psychology and training that should be valuable to academics and practitioners alike.

This book focuses on contemporary human factors issues within the design of soldier systems and describes how they are currently being investigated and addressed by the U.S. Army to enhance soldier performance and effectiveness. Designing Soldier Systems approaches human factors issues from three main perspectives. In the first section, Chapters 1-5 focus on complexity introduced by technology, its impact on human performance, and how issues are being addressed to reduce cognitive workload. In the second section, Chapters 6-10 concentrate on obstacles imposed by operational and environmental conditions on the battlefield and how they are being mitigated through the use of technology. The third section, Chapters 11-21, is dedicated to system design and evaluation including the tools, techniques and technologies used by researchers who design soldier systems to overcome human physical and cognitive performance limitations as well as the obstacles imposed by environmental and operations conditions that are encountered by soldiers. The book will appeal to an international multidisciplinary audience interested in the design and development of systems for military use, including defense contractors, program management offices, human factors engineers, human system integrators, system engineers, and computer scientists. Relevant programs of study include those in human factors, cognitive science, neuroscience, neuroergonomics, psychology, training and education, and engineering.

This book provides an overview of state-of-the-art research that has been conducted within Australia, funded by the Bushfire Cooperative Research Centre. The chapters source and contextualize their own research practice within the context of the international research literature. Therefore, while the research has occurred within Australia it will be of particular interest to scholars, students and practitioners in a number of other countries, particularly within the United States of America and in Europe. The fire and emergency services is a particularly large industry - in Australia alone it employs 250,000 personnel - yet there is very little by way of published human factors books addressing this sector directly. Emergency events frequently involve problems for which there may be unanticipated consequences and highly interdependent consequential effects. In short, emergency events are not necessarily as containable as may be work in other domains. As Karl Weick once commented, emergency events do not 'play by the rules'. This means that these research chapters tell us something about a potential future world of work that is highly dynamic, interdependent and for which improvisation and critical thinking and problem-solving are necessary pre-requisites. The discussions about individual and team performance will also be pertinent to others working in similar high-reliability, high-consequence domains. The chapters connect into an integrated body of work about individual and group performance and their limitations.

The objective of this book is to report on contemporary trends in the defence research community on trust in teams, including inter- and intra-team trust, multi-agency trust and coalition trust. The book also considers trust in information and automation, taking a systems view of humans as agents in a multi-agent, socio-technical, community. The different types of trust are usually found to share many of the same emotive, behavioural, cognitive and social constructs, but differ in the degree of importance associated with each of them. Trust in Military Teams is written by defence scientists from the USA, Canada, Australia and the UK, under the auspices of The Transfer Cooperation Programme. It is representative of the latest thinking on trust in teams, and is written for defence researchers, postgraduate students, academics and practitioners in the human factors community.

This book presents the latest work in the area of naturalistic decision making (NDM) and its extension into the area of macrocognition. It contains 18 chapters relating research centered on the study of expertise in naturalistic settings, written by international experts in NDM and cognitive systems engineering. The objective of the book is to present the reader with exciting new developments in this field of research, which is characterized by its application-oriented focus. The work addresses only real-world problems and issues. For instance, how do multi-national teams collaborate effectively? How can surgeons best be supported by technology? How do detectives make sense of complex criminal cases? In all instances the studies have been carried out on experts within their respective domains. The traditional field of NDM is extended in this work by focusing on macrocognitive functions other than decision making, namely sense-making, coordination and planning. This has broadened the scope of the field. The book also contains a theoretical discussion of the macro-micro distinction. Naturalistic Decision Making and Macrocognition will be relevant to graduate students, researchers and professionals (including professionals and researchers in business, industry and government) who are interested in decision making, expertise, training methods and system design. The material may be used in two ways: theoretically, to advance understanding of the field of naturalistic decision making; and practically, to gain insight into how experts in various domains solve particular problems, understand and deal with issues and collaborate with others.

While there have been tremendous advances in our scientific understanding of the brain, this work has been largely academic, and often oriented toward clinical publication. Cognitive Neuroscience of Human Systems: Work and Everyday Life addresses the relationship between neurophysiological processes and the performance and experience of humans in everyday life. It samples the vast neuroscience literature to identify those areas of research that speak directly to the performance and experience of humans in everyday settings, highlighting the practical, everyday application of brain science. The book explains the underlying basis for well-established principles from human factors, ergonomics, and industrial engineering and design. It also sheds new light on factors affecting human performance and behavior. This is not an academic treatment of neuroscience, but rather a translation that makes modern brain science accessible and easily applicable to systems design, education and training, and the development of policies and practices. The authors supply clear and direct guidance on the applications of principles from brain science to everyday problems. With discussions of topics from brain science and their relevance to everyday activities, the book focuses on the science, describing the findings and the studies producing these findings. It then decodes how these findings relate to everyday life and how you can integrate them into your work to achieve more effective outcomes based on a fundamental understanding of how the operations of the human brain produce behavior and modulate performance.

Many books focus on individual differences and how those relate to traffic safety such as accident proneness, gender differences, age, alcohol, and the effects of drugs. Others focus on the safety effects regarding the vehicle such as airbags, anti-lock brakes, navigation systems, intelligent cruise control and other new gadgets coming to the vehicle. Even though these topics are undoubtedly important for traffic safety, this book takes a unique approach as it focuses solely on the road environment. Designing Safe Road Systems provides the background for those who want to know more about the effects of road design on driving behaviour. It uses a systems approach to allow a better understanding of why and in what circumstances drivers may commit errors. This understanding will ultimately lead to road systems that prevent (fatal) errors from occurring. The book contains an overview of the current models and theories about human performance and human behaviour in traffic that are relevant for all those involved in designing safe road systems. The central theme of this book is how design principles can reduce the probability of an error while driving. The authors demonstrate how knowledge of human factors helps a road authority to better understand how road users behave. They argue that in many cases the design of the environment can be further adjusted to human capabilities, and that safety should be considered a system property to be built into the road system.

This book discusses several methodological problems in traffic psychology which are not currently recognized as such. Summarizing and analyzing the available research, it is found that there are a number of commonly made assumptions about the validity of methods that have little backing, and that many basic problems have not been researched at all. Suggestions are made as to further studies that should be made to address some of these problems. The book is primarily intended for traffic/transport researchers, but should also be useful for specialized education at a higher level (doctoral students and transportation specialists) as well as officials who require a good grasp of methodology to be able to evaluate research.

Acceptance of new technology and systems by drivers is an important area of concern to governments, automotive manufacturers and equipment suppliers, especially technology that has significant potential to enhance safety. To be acceptable, new technology must be useful and satisfying to use. If not, drivers will not want to have it, in which case it will never achieve the intended safety benefit. Even if they have the technology, drivers may not use it if it is deemed unacceptable, or may not use it in the manner intended by the designer. At worst, they may seek to disable it. This book brings into a single edited volume the accumulating body of thinking and research on driver and operator acceptance of new technology. Bringing together contributions from international experts from around the world, the editors have shaped a book that covers the theory behind acceptance, how it can be measured and how it can be improved. Case studies are presented that provide data on driver acceptance of a wide range of new and emerging vehicle technology. Although driver acceptance is the central focus of this book, acceptance of new technology by operators in other domains, and across cultures, is also investigated. Similarly, perspectives are derived from domains such as human computer interaction, where user acceptance has long been regarded as a key driver of product success. This book comes at a critical time in the history of the modern motor vehicle, as the number of new technologies entering the modern vehicle cockpit rapidly escalates. The goal of this book is to inspire further research and development of new vehicle technology to optimise user acceptance of it; and, in doing so, to maximise its potential to be useful, satisfying to use and able to save human life.

Understanding the conditions under which variability in performance may arise, and the processes related to its emergence, gives us insight into the development of techniques for improving the quality of performance. Variability in Human Performance details the scientific and the practical implications of human performance variability by providing a broad perspective on how and why such variability occurs across a number of disciplinary domains. The text takes an approach that rests upon the idea of context, or design, specificity in performance, namely that variability in performance is closely referenced to design factors in the environment in which performance is occurring. An exploration of the link between variability and related processes, the book introduces a comprehensive framework for understanding human performance variability, presented in terms of how human control of behavior is closely tied to design factors in the performance environment. The authors introduce empirical evidence, as well as practical examples and application areas, in support of this framework. The book begins with coverage of neurobiological and biomechanical basis of movement variability, then examines rich and extensive empirical evidence available for context specificity in cognitive performance and learning, as a basis for cognitive performance variability. The book then reviews the evidence for context specificity in: Student learning Displaced feedback conditions Human error behavior Affective performance Social and team performance The authors also explore work performance as influenced by complex sociotechnical systems and as a basis for performance variability, applying control systems concepts to an interpretation of the nature and basis of performance variability in all of these domains. They conclude by taking an evolutionary perspective on the origins and behavioral significance of human performance variability. The book then provides strategies on how individuals, groups, and organizations can significantly reduce variability in human performance that often leads to systems failures.
