The standard model (SM) of particle physics is a hugely successful theory of nature, but it is incomplete. E.g., it cannot explain finite SM neutrino masses or the origin of the primordial baryon asymmetry (BAU). One way to address such problems is to postulate the existence of new but hidden particles. This thesis studies such "hidden sectors" in two ways: 1) An effective theory approach, where electroweak (EW) and GeV scale portal effective theories (PETs) are constructed that couple the SM to a generic light hidden mediator of spin 0, 1⁄2, or 1. The EW scale PETs include all portal operators of dimension d≤5. The GeV scale PETs additionally include all leading order (LO) flavour changing portal operators of dimension d≤6,7. They are used to derive a LO PET chiral perturbation theory Lagrangian that describes hidden sector induced light meson transitions in fixed target experiments like NA62 or SHiP. 2) An investigation of the type-I seesaw model, which couples the SM to n≥2 sterile neutrinos that can generate a BAU via “leptogenesis”. It is shown that thermal and spectator effects can result in a sign-flip and strong relative enhancement of the BAU in high-scale leptogenesis with two hierarchical sterile neutrinos of vanishing initial abundance. Much lighter sterile neutrinos may be detected via lepton number violating (LNV) decays at colliders, but LNV decays could be suppressed relative to lepton number conserving decays for 't Hooft natural parameter choices. It is shown that the corresponding parameter space consists of three regions: (a)with unsuppressed LNV decays, (b)with suppressed LNV decays, (c)with suppressed and unsuppressed LNV decays.

How can greenhouse gases be controlled and reduced? Will it be in time? This book adds a significant new contribution to the crucial climate change/global warming debate. Incorporating the key political and legal considerations into `real world' applied economic analysis, the authors provide a unique focus on the wider political economy of the problem. All the key issues of controlling climate change (costs, timing and degree of stabilisation, ecological taxt reform, developing countries, and evolution of international agreements), are placed firmly within the current legal and political context, with state-of-the-art economic techniques introduced to analyse different policy proposals. Covering both the developing and developed world, this book identifies important new policies to foster effective agreements on eissions and prevent global warming - realistic policies, likely to receive support at both international and domestic levels. be in time?

This book presents the latest research in the fields of reliability theory and its applications, providing a comprehensive overview of reliability engineering and discussing various tools, techniques, strategies and methods within these areas. Reliability analysis is one of the most multidimensional topics in the field of systems reliability engineering, and while its rapid development creates opportunities for industrialists and academics, it is also means that it is hard to keep up to date with the research taking place. By gathering findings from institutions around the globe, the book offers insights into the international developments in the field. As well as discussing the current areas of research, it also identifies knowledge gaps in reliability theory and its applications and highlights fruitful avenues for future research. Covering topics from life cycle sustainability to performance analysis of cloud computing, this book is ideal for upper undergraduate and postgraduate researchers studying reliability engineering.

Originally published in 1999, The Kyoto Protocol provides a detailed discussion on the history, terms and implications of the Kyoto Protocol 1997. It explains the meaning of provision on emissions trading and other flexibility mechanisms, and provides a quantitative analysis using the Energy and Environment Programme's emissions trading model. It also contains the full text of the Kyoto Protocol and developments at the 4th Conference of the Parties in December 1998. This book will be of interest to academics working in the field of climate change, as well as the broader area of environment and sustainability.

The International Conference, Orbis Scientiae 1996, focused on the topics: The Neutrino Mass, Light Cone Quantization, Monopole Condensation, Dark Matter, and Gravitational Waves which we have adopted as the title of these proceedings. Was there any exciting news at the conference? Maybe, it depends on who answers the question. There was an almost unanimous agreement on the overall success of the conference as was evidenced by the fact that in the after-dinner remarks by one of us (BNK) the suggestion of organizing the conference on a biannual basis was presented but not accepted: the participants wanted the continuation of the tradition to convene annually. We shall, of course, comply. The expected observation of gravitational waves will constitute the most exciting vindication of Einstein's general relativity. This subject is attracting the attention of the experimentalists and theorists alike. We hope that by the first decade of the third millennium or earlier, gravitational waves will be detected, opening the way for a search for gravitons somewhere in the universe, presumably through the observations in the CMBR. The theoretical basis of the graviton search will take us to quantum gravity and eventually to the modification of general relativity to include the Planck scale behavior of gravity -at energies 19 of the order of 10 Ge V.

This book describes guidelines prepared by the U.S. Country Studies Program for the evaluation of options to mitigate greenhouse gas emissions. The U.S. Country Studies Program developed these guidelines in collaboration with Lawrence Berkeley National Laboratory to provide developing countries and countries with economies in transition with reference materials for national mitigation assessments. Over 50 countries participating in the program have used the guidelines, which have been refined to reflect their comments. The guidelines delineate a step-wise methodology for evaluating greenhouse gas mitigation options for the energy and non-energy sectors and describe the applications of common analytical tools. The U.S. Country Studies Program uses these guidelines in conjunction with intensive training workshops and follow up technical assistance during the lifetime of each country's study. The program uses similar reference materials to assist counties with their greenhouse gas emission inventories and evaluations of climate change vulnerability and adaptive responses. These guidelines serve three purposes: to assist countries in making decisions about the scope and methodology for mitigation assessments; to provide countries with guidance and step-by-step instructions on each element of a mitigation assessment; and to help countries determine which analytical tools are best suited to their needs and describe procedures for applying these tools. This book describes the application of the most common and readily available methods and analytical tools. Countries are encouraged, where appropriate, to use their own methods.

A perspective on the public sector that presents a concise and comprehensive analysis of exactly what it is and how it operates. Governments in any society deliver a large number of services and goods to their populations. To get the job done, they need public management in order to steer resources – employees, money and laws – into policy outputs and outcomes. In well-ordered societies the teams who work for the state work under a rule-of-law framework, known as public administration. This book covers the key issues of: the principal-agent framework and the public sector public principals and their agents the economic reasons of government public organization, incentives and rationality in government the essence of public administration: legality and the rule of law public policy criteria: the Cambridge and Chicago positions public teams and private teams public firms public insurance public management policy Public Administration & Public Management is essential reading for those with professional and research interests in public administration and public management.
