The Illusion of Risk Control
Author: Gilles MotetPublisher: Springer
ISBN: 3319329391
Category : Technology & Engineering
Languages : en
Pages : 113
Book Description
This book is open access under a CC BY 4.0 license. This book explores the implications of acknowledging uncertainty and black swans for regulation of high-hazard technologies, for stakeholder acceptability of potentially hazardous activities and for risk governance. The conventional approach to risk assessment, which combines the likelihood of an event and the severity of its consequences, is poorly suited to situations where uncertainty and ambiguity are prominent features of the risk landscape. The new definition of risk used by ISO, “the effect of uncertainty on [achievement of] one’s objectives”, recognizes this paradigm change. What lessons can we draw from the management of fire hazards in Edo-era Japan? Are there situations in which increasing uncertainty allows more effective safety management? How should society address the risk of potentially planet-destroying scientific experiments? This book presents insights from leading scholars in different disciplines to challenge current risk governance and safety management practice.
An Introduction to European Intergovernmental Organizations
Author: Marc CogenPublisher: Routledge
ISBN: 1317181816
Category : Political Science
Languages : en
Pages : 301
Book Description
An Introduction to European Intergovernmental Organizations provides an up-to-date and accessible reference to European intergovernmental organizations other than the European Union. The EU is so dominant that people often overlook the multitude of older and newer, smaller and larger intergovernmental organizations rooted in the history of contemporary Europe which continue to help shape its future. The specialized character of these organizations adds value to cooperation in Europe as a whole, creates permanent channels of communication regardless of EU membership and allows the possibility for non-European involvement through organizations such as the European Bank for Reconstruction and Development and NATO. It also allows sub regional groups of states, such as the Nordic countries or the Benelux countries to exist and express their own identity via their own organizations. This book looks at the history of Non-EU organizations, their decision-making characteristics, membership policies, legal powers actions and interactions with each other and the European Union. A uniform scheme of analysis is used to make European intergovernmental organizations comparable and by studying them we gain a deeper understanding and insight into European affairs.

Book Description
An accessible look at the hottest topic in physics and the experiments that will transform our understanding of the universe The biggest news in science today is the Large Hadron Collider, the world's largest and most powerful particle-smasher, and the anticipation of finally discovering the Higgs boson particle. But what is the Higgs boson and why is it often referred to as the God Particle? Why are the Higgs and the LHC so important? Getting a handle on the science behind the LHC can be difficult for anyone without an advanced degree in particle physics, but you don't need to go back to school to learn about it. In Collider, award-winning physicist Paul Halpern provides you with the tools you need to understand what the LHC is and what it hopes to discover. Comprehensive, accessible guide to the theory, history, and science behind experimental high-energy physics Explains why particle physics could well be on the verge of some of its greatest breakthroughs, changing what we think we know about quarks, string theory, dark matter, dark energy, and the fundamentals of modern physics Tells you why the theoretical Higgs boson is often referred to as the God particle and how its discovery could change our understanding of the universe Clearly explains why fears that the LHC could create a miniature black hole that could swallow up the Earth amount to a tempest in a very tiny teapot "Best of 2009 Sci-Tech Books (Physics)"-Library Journal "Halpern makes the search for mysterious particles pertinent and exciting by explaining clearly what we don't know about the universe, and offering a hopeful outlook for future research."-Publishers Weekly Includes a new author preface, "The Fate of the Large Hadron Collider and the Future of High-Energy Physics" The world will not come to an end any time soon, but we may learn a lot more about it in the blink of an eye.

Massive
Author: Ian SamplePublisher: Basic Books
ISBN: 0465031692
Category : Science
Languages : en
Pages : 274
Book Description
The biggest science story of our time, Massive spans four decades, weaving together the personal narratives and international rivalries behind the search for the "God" particle, or Higgs boson. A story of grand ambition, intense competition, clashing egos, and occasionally spectacular failures, Massive is the first book that reveals the science, culture, and politics behind the biggest unanswered question in modern physics -- what gives things mass? Drawing upon his unprecedented access to Peter Higgs, after whom the particle is named, award-winning science writer Ian Sample chronicles the multinational and multibillion-dollar quest to solve the mystery of mass. For scientists, to find the God particle is to finally understand the origin of mass, and until now, the story of their search has never been told.
Large Hadron Collider
Author: The Argumentative Turn in Policy Analysis
Author: Sven Ove HanssonPublisher: Springer
ISBN: 3319305492
Category : Science
Languages : en
Pages : 354
Book Description
This book describes argumentative tools and strategies that can be used to guide policy decisions under conditions of great uncertainty. Contributing authors explore methods from philosophical analysis and in particular argumentation analysis, showing how it can be used to systematize discussions about policy issues involving great uncertainty. The first part of the work explores how to deal in a systematic way with decision-making when there may be plural perspectives on the decision problem, along with unknown consequences of what we do. Readers will see how argumentation tools can be used for prioritizing among uncertain dangers, for determining how decisions should be framed, for choosing a suitable time frame for a decision, and for systematically choosing among different decision options. Case studies are presented in the second part of the book, showing argumentation in practice in the areas of climate geoengineering, water governance, synthetic biology, nuclear waste, and financial markets. In one example, argumentation analysis is applied to proposals to solve the climate problem with various technological manipulations of the natural climate system, such as massive dispersion of reflective aerosols into the stratosphere. Even after a thorough investigation of such a proposal, doubt remains as to whether all the potential risks have been identified. In such discussions, conventional risk analysis does not have much to contribute since it presupposes that the risks have been identified, whereas the argumentative approach to uncertainty management can be used to systematize discussions.

Author: Jet-hadron Correlations Relative to the Event Plane in Pb-Pb Collisions at the LHC in ALICE

Category : Hadron interactions
Languages : en
Pages : 224
Book Description
In relativistic heavy ion collisions at the Large Hadron Collider (LHC), a hot, dense and strongly interacting medium known as the Quark Gluon Plasma (QGP) is produced. Quarks and gluons from incoming nuclei collide to produce partons at high momenta early in the collisions. By fragmenting into collimated sprays of hadrons, these partons form 'jets'. Within the framework of perturbative Quantum Chromodynamics (pQCD), jet production is well understood in pp collisions. We can use jets measured in pp interactions as a baseline reference for comparing to heavy ion collision systems to detect and study jet quenching. The jet quenching mechanism can be studied through the angular correlations of trigger jets with charged hadrons and is examined in transverse momentum bins of the trigger jets, transverse momentum bins of the associated hadrons, and studied as a function of collision centrality. A highly robust and precise background subtraction method is used in this analysis to remove the complex, flow dominated, heavy ion background. The analysis of angular correlations for different orientations of the trigger jet relative to the event plane allows for the study of the path length dependence of medium modifications to jets. The event plane dependence of azimuthal angular correlations of charged hadrons with respect to the axis of an R=0.2 reconstructed 'trigger' full (charged + neutral) jet in Pb--Pb collisions at [square root s subscript NN] 2.76 TeV in ALICE will be discussed. Results will be compared for three angular bins of the trigger jet relative to the event plane in mid-peripheral events. The status of jet yields and widths relative to the event plane will be discussed. There is no significant event plane dependence within the current uncertainties. Path length dependence of energy loss is seen to be a secondary effect to statistical fluctuations and in-medium energy loss mechanisms.
