Any practical process of risk ranking must group hazards into a manageable number of categories. Defining such categories requires value choices that can have important implications for the rankings that result. Most risk‐management organizations will find it useful to begin defining categories in terms of environmental loadings or initiating events. However, the resulting categories typically need to be modified in light of other considerations. Risk‐ranking projects can benefit from considering several alternative categorization strategies and drawing upon elements of each in developing their final categorization of risks. In principle, conducting multiple ranking exercises by using different categorizations could be interesting and useful. In practice, agencies are unlikely to have either the resources or patience to do this, but other groups in society might. Done well, such additional independent rankings could add valuable inputs to democratic risk‐management decision making.

This product is not available separately, it is only sold as part of a set. There are 750 products in the set and these are all sold as one entity, Risk assessment is considered by many analysts to be an objective scientific tool. It is considered to be variously influenced by broader issues which in turn have important practical implications both for risk assessors and decision makers. Risk Assessment and Risk Management examines a range of practical applications of risk assessment methods and risk management procedures in the broad context of environmental science and technology. Written by acknowledged experts in the field, the articles cover a variety of areas, with reference to subjects as diverse as BSE, the use of risk assessment in government, using computer modelling as an aid to risk assessment in the case of accidental contamination of rivers and estuaries, quantitative cancer risk assessment related to carcinogens in the environment, landfilling of household wastes, environmental risk assessment and management of chemicals, and aquatic risk assessment and management of pesticides. This book provides a detailed and wide-ranging review of the many aspects of risk assessment and risk management which have excited so much debate and controversy in recent times. It will be essential reading for all those involved in the assessment and management of risk, particularly in the context of environmental science

"Nach dem Ende des Ost-West-Konflikts ist die Welt nicht ein ruhigerer Ort geworden, wie von vielen vorausgesagt. Eher im Gegenteil. Zahlreiche Krisenherde und Konfliktfelder sind zu registrieren. Globalisierung führt nur teilweise zu Integration und Homogenisierung. In vielen Bereichen und Regionen fragmentiert sich die Weltgesellschaft. Sogenannte neue Risiken verschränken sich mit älteren. Die Themenbeiträge widmen sich den Neuen Kriegen und gewaltförmiger Konfliktaustragung; demographischen Veränderungen; den Kontextfaktoren Energie und Umwelt; Aids, stellvertretend für gesundheitliche Risiken; dem Komplex der neuen Wissensdifferenzen und Zugangsschranken; der Gefährdung von Infrastrukturen; der Bedeutung von Strömen (flows) - an den Beispielen von Kapital und Kommunikation; der Bedeutung von Identitäten und deren Irritationen; der Rolle und dem Ge- und Missbrauch von Medien; der verbleibenden oder auch neuen Rolle von Politik; und, damit verbunden, aber auch Unterschieden, den residualen Funktionen von Staaten." (Textauszug).

"Recent events from the economic downturn to climate change mean that there has never been a better time to be thinking about and trying to better understand the concept of risk. In this book, prominent and eminent speakers from fields as diverse as statistics to classics, neuroscience to criminology, politics to astronomy, as well as speakers embedded in the media and in government have put their ideas down on paper in a series of essays that broaden our understanding of the meaning of risk. After twenty-five years, the prestigious Darwin College Lectures are one of the most popular public lecture series at the University of Cambridge. The risk lectures in 2010 were amongst the most popular yet and, in essay form, they make for a lively and engaging read for specialists and non-specialists alike"--

Since the terrorist attacks of September 11, 2001, and the subsequent establishment of the U.S. Department of Homeland Security (DHS), considerable efforts have been made to estimate the risks of terrorism and the cost effectiveness of security policies to reduce these risks. DHS, industry, and the academic risk analysis communities have all invested heavily in the development of tools and approaches that can assist decisionmakers in effectively allocating limited resources across the vast array of potential investments that could mitigate risks from terrorism and other threats to the homeland. Decisionmakers demand models, analyses, and decision support that are useful for this task and based on the state of the art. Since terrorism risk analysis is new, no single method is likely to meet this challenge. In this article we explore a number of existing and potential approaches for terrorism risk analysis, focusing particularly on recent discussions regarding the applicability of probabilistic and decision analytic approaches to bioterrorism risks and the Bioterrorism Risk Assessment methodology used by the DHS and criticized by the National Academies and others.
