Book excerpt: Over the past several years, we have begun to fully appreciate the value of probabilistic risk assessment (PRA) as a decision support tool. Risk assessment has allowed us to focus on problems of real importance and provided discipline to prioritization processes. Many government agencies now consider risk assessment as a normal and essential element of their decision making. Due to the inherent uncertainty in the results, use of absolute PRA numbers to make specific decisions was not encouraged by risk assessment experts in the past. The current trend, however, is to make more and more use of the absolute numbers and (in some cases) to use them directly to make regulatory decisions. Whether or not we approve of this trend, it will almost certainly continue. Therefore, it is incumbent upon risk assessment experts to provide information to decision-makers that is properly characterized. This characterization should include a clear presentation of the uncertainties involved in the risk estimates. Uncertainty analysis is often considered undesirable by decision-makers, because it muddies up the waters of an other-wise clear cut decision.
Download or read book Uncertainty in Risk Assessment Risk Management and Decision Making written by V.T. Covello and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this volume--uncertainties in risk assessment and management--reflects an important theme in health, safety, and environ mental decision making. MOst technological hazards are characterized by substantial uncertainty. Recent examples include nuclear waste disposal, acid rain, asbestos in schools, carcinogens in food, and hazardous waste. realing with such uncertainty is arguably the most difficult and challeng ing task facing risk assessors and managers today. Four primary sources of uncertainty in risk assessment and management can be identified: (1) uncertainties about definitions; (2) uncertainties about scientific facts; (3) uncertainties about risk perceptions and atti tudes; and (4) uncertainties about values. Uncertainties about definitions derive primarily from disagreements about the meaning and interpretation of key concepts, such as probability. Uncertainties about scientific facts derive primarily from disagreements about failure modes, the probability and magnitude of adverse health or environmental consequences, cause and effect relationships, dose-response relationships, and exposure patterns. Uncertainties about risk perceptions and attitudes derive primarily from disagreements about what constitutes a significant or acceptable level of risk. Uncertainties about values derive primarily from disagreements about the desirability or worth of alternative risk management actions or conse quences. The papers in this volume address each of these sources of uncertainty from a variety of perspectives. Reflecting the broad scope of risk assess ment and risk management research, the papers include contributions from safety engineers, epidemiologists, toxicologists, chemists, biostatisticians, biologists, decision analysts, economists, psychologists, political scien tists, sociologists, ethicists, and lawyers.
Download or read book Science and Judgment in Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 1994-01-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: The public depends on competent risk assessment from the federal government and the scientific community to grapple with the threat of pollution. When risk reports turn out to be overblownâ€"or when risks are overlookedâ€"public skepticism abounds. This comprehensive and readable book explores how the U.S. Environmental Protection Agency (EPA) can improve its risk assessment practices, with a focus on implementation of the 1990 Clean Air Act Amendments. With a wealth of detailed information, pertinent examples, and revealing analysis, the volume explores the "default option" and other basic concepts. It offers two views of EPA operations: The first examines how EPA currently assesses exposure to hazardous air pollutants, evaluates the toxicity of a substance, and characterizes the risk to the public. The second, more holistic, view explores how EPA can improve in several critical areas of risk assessment by focusing on cross-cutting themes and incorporating more scientific judgment. This comprehensive volume will be important to the EPA and other agencies, risk managers, environmental advocates, scientists, faculty, students, and concerned individuals.

This book was released on 1999 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fiscal and technological limitations associated with cleaning up hazardous waste sites to background conditions have prompted responsible parties to turn to risk-based methods for environmental rememdiation. Environmental Cleanup at Navy Facilities reviews and critiques risk-based methods, including those developed by the U.S. Environmental Protection Agency and the American Society of Testing and Materials. These critiques lead to the identification of eleven criteria that must be part of any risk-based methodology adopted by the Navy, a responsible party with a large number of complex and heavily contaminated waste sites.

Download or read book Uncertain Risks Regulated written by Ellen Vos and published by Routledge. This book was released on 2009-01-26 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertain Risks Regulated compares various models of risk regulation in order to understand how these systems shape the relationship between law and science, and how they attempt to overcome public distrust in science-based decision-making. The book contributes to the ongoing debate relating to uncertainty and risks - and the difficulties faced by the European Union in particular - in regulating theses issues, taking account of both national and international constraints. The term 'uncertain risk' is comparable with notions of hazard and indeterminate risk, as deployed within the social sciences; but it also aims to capture the modern regulatory reality that a non-quantifiable hazard must still be addressed by society, law and its regulators. Decisions must be taken in the face of uncertainty. And, whilst it is not possible to provide clear cut models of risk regulation, in focusing on regulatory practices at a national, EU and international level, the contributors to this volume aim to use fact finding as a core instrument of learning for risk regulation.
Download or read book Uncertainty in Industrial Practice written by Etienne de Rocquigny and published by John Wiley & Sons. This book was released on 2008-09-15 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managing uncertainties in industrial systems is a daily challenge to ensure improved design, robust operation, accountable performance and responsive risk control. Authored by a leading European network of experts representing a cross section of industries, Uncertainty in Industrial Practice aims to provide a reference for the dissemination of uncertainty treatment in any type of industry. It is concerned with the quantification of uncertainties in the presence of data, model(s) and knowledge about the system, and offers a technical contribution to decision-making processes whilst acknowledging industrial constraints. The approach presented can be applied to a range of different business contexts, from research or early design through to certification or in-service processes. The authors aim to foster optimal trade-offs between literature-referenced methodologies and the simplified approaches often inevitable in practice, owing to data, time or budget limitations of technical decision-makers. Uncertainty in Industrial Practice: Features recent uncertainty case studies carried out in the nuclear, air & space, oil, mechanical and civil engineering industries set in a common methodological framework. Presents methods for organizing and treating uncertainties in a generic and prioritized perspective. Illustrates practical difficulties and solutions encountered according to the level of complexity, information available and regulatory and financial constraints. Discusses best practice in uncertainty modeling, propagation and sensitivity analysis through a variety of statistical and numerical methods. Reviews recent standards, references and available software, providing an essential resource for engineers and risk analysts in a wide variety of industries. This book provides a guide to dealing with quantitative uncertainty in engineering and modelling and is aimed at practitioners, including risk-industry regulators and academics wishing to develop industry-realistic methodologies.

Download or read book Science and Decisions written by National Research Council and published by National Academies Press. This book was released on 2009-03-24 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.
Download or read book The Tyranny of Uncertainty written by Nabil Abu el Ata and published by Springer. This book was released on 2016-05-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors offer a revolutionary solution to risk management. It’s the unknown risks that keep leaders awake at night—wondering how to prepare for and steer their organization clear from that which they cannot predict. Businesses, governments and regulatory bodies dedicate endless amounts of time and resources to the task of risk management, but every leader knows that the biggest threats will come from some new chain of events or unexpected surprises—none of which will be predicted using conventional wisdom or current risk management technologies and so management will be caught completely off guard when the next crisis hits. By adopting a scientific approach to risk management, we can escape the limited and historical view of experience and statistical based risk management models to expose dynamic complexity risks and prepare for new and never experienced events.
Download or read book Environmental Decisions in the Face of Uncertainty written by Institute of Medicine and published by National Academies Press. This book was released on 2013-05-20 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) is one of several federal agencies responsible for protecting Americans against significant risks to human health and the environment. As part of that mission, EPA estimates the nature, magnitude, and likelihood of risks to human health and the environment; identifies the potential regulatory actions that will mitigate those risks and protect public health1 and the environment; and uses that information to decide on appropriate regulatory action. Uncertainties, both qualitative and quantitative, in the data and analyses on which these decisions are based enter into the process at each step. As a result, the informed identification and use of the uncertainties inherent in the process is an essential feature of environmental decision making. EPA requested that the Institute of Medicine (IOM) convene a committee to provide guidance to its decision makers and their partners in states and localities on approaches to managing risk in different contexts when uncertainty is present. It also sought guidance on how information on uncertainty should be presented to help risk managers make sound decisions and to increase transparency in its communications with the public about those decisions. Given that its charge is not limited to human health risk assessment and includes broad questions about managing risks and decision making, in this report the committee examines the analysis of uncertainty in those other areas in addition to human health risks. Environmental Decisions in the Face of Uncertainty explains the statement of task and summarizes the findings of the committee.
Download or read book Organized Uncertainty written by Michael Power and published by OUP Oxford. This book was released on 2007-05-24 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the mid-1990s risk management has undergone a dramatic expansion in its reach and significance, being transformed from an aspect of management control to become a benchmark of good governance for banks, hospitals, schools, charities and many other organizations. Numerous standards for risk management practice have been produced by a variety of transnational organizations. While these many designs and blueprints are accompanied by ideals of enterprise, value production, and good governance, it is argued that the rise of risk management has also coincided with an intensification of auditing and control processes. The legalization and bureacratization of organizational life has increased because risk management has created new demands for proof and evidence of action. In turn, these demands have generated new risks to reputation. In short, this important book traces the rise of the managerial concept of risk and the different logics and values which underpin it, showing that it has much less to do with real dangers and opportunities than might be thought, and more to do with organizational accountability and legitimacy.

Download or read book Characterizing and Communicating Uncertainty in the Assessment of Benefits and Risks of Pharmaceutical Products written by Institute of Medicine and published by National Academies Press. This book was released on 2014-12-19 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the extensive body of evidence that informs regulatory decisions on pharmaceutical products, significant uncertainties persist, including the underlying variability in human biology, factors associated with the chemistry of a drug, and limitations in the research and clinical trial process itself that might limit the generalizability of results. As a result, regulatory reviewers are consistently required to draw conclusions about a drug's safety and efficacy from imperfect data. Efforts are underway within the drug development community to enhance the evaluation and communication of the benefits and risks associated with pharmaceutical products, aimed at increasing the predictability, transparency, and efficiency of pharmaceutical regulatory decision making. Effectively communicating regulatory decisions necessarily includes explanation of the impact of uncertainty on decision making. On February 12 and May 12, 2014, the Institute of Medicine's Forum on Drug Discovery, Development, and Translation held public workshops to advance the development of more systematic and structured approaches to characterize and communicate the sources of uncertainty in the assessment of benefits and risks, and to consider their implications for pharmaceutical regulatory decisions. Workshop presentations and discussions on February 12 were convened to explore the science of identifying and characterizing uncertainty in scientific evidence and approaches to translate uncertainties into decisions that reflect the values of stakeholders. The May 12 workshop presentations and discussions explored tools and approaches to communicating about scientific uncertainties to a range of stakeholders in the drug development process. Characterizing and Communicating Uncertainty in the Assessment of Benefits and Risks of Pharmaceutical Products summarizes the presentation and discussion of both events. This report explores potential analytical and communication approaches and identifies key considerations on their development, evaluation, and incorporation into pharmaceutical benefit- risk assessment throughout the entire drug development lifecycle.
Download or read book Risk Management and Hazardous Waste written by Brian Wynne and published by Springer. This book was released on 2011-12-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyses the treatment of uncertainties within risk management and regulation for hazardous wastes, in five national case-studies. It is shown that, although institutional uncertainties vary between national political cultures, regulatory bureaucracies everywhere understate these more fundamental uncertainties (which are often structural conflicts, of different rationalities) and define them instead as marginal technical uncertainties or imprecision in risk-definitions. Close comparative analysis shows that technical regulatory standards depend upon their local institutional setting in systematic ways, so that conventional regulatory emphasis on technical precision or standardisation should be replaced by greater social negotiation, and educated public involvement and control. Readers will find the book valuable for its novel analytical approach especially in relation to public acceptance issues, and the argument for fresh practical approaches derived from this; in addition there is new information and analysis from the descriptive materials in case studies. Its main aim is to stimulate fresh thinking and approaches to an urgent problem.
Download or read book Organizations Uncertainties And Risk written by James F. Short, Jr. and published by Westview Press. This book was released on 1992-08-26 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every day, individuals, groups, and organizations make decisions that involve uncertainty and risk - and, often, important consequences for society. Increasingly, our lives are being defined by large-scale organizational decision processes involving governments, businesses and other institutions. This book examines the nature of decisionmaking by organizations confronted with various risks, focusing on choices in which technology and scientific advances play major roles. The contributors also look at the regulatory agencies that set and enforce standards of health and safety. Within the literature on risk analysis this book is unique in its integration of social theory with wide variety of case examples. Theories of rational choice advanced by neoclassical economics and cognitive psychology are critically examined in view of the importance of the context for decisionmaking. Specific avenues for the study of the organizational/institutional contexts of decisionmaking and the process of socially constructing risk objects are proposed as a means of correcting the weaknesses of these theories. The contributors examine the strategies of manufacturing and communications firms, neonatal intensive care units of hospitals, and a major U.S. governmental strategies are given: how energy choices are made in France and how expert advice and formal public involvement are incorporated into risk-related policy decisions in Britain. Field studies of regulatory agencies in Britain at both policymaking and enforcement levels are also included.
