The emission trading scheme is the most recent instrument of the EU environmental policy. Its underlying mechanisms and economic consequences are yet less straightforward than policymakers initially had expected: As this study shows, the regulation probably yields unintended distributional effects and imposes additional risk on the regulated companies. Consequently, meaningful accounting for emission rights is not only a necessity for regulators and customers, who need transparency, but also for investors on capital markets, who bear the additional regulatory risk. This study empirically assesses the usefulness of various accounting alternatives and provides evidence that cost and fair value approaches dominate the widely used mixed models.

This book presents a holistic view on compiler assisted practical secure multi-party computation (MPC) over Boolean circuits. It discusses that two or more parties jointly evaluate a function over their inputs in such a way that each party keeps its input unknown to the other parties in MPC. MPC provides a generic way to construct Privacy-Enhancing Technologies, which protect sensitive data during processing steps in untrusted environments. A major obstacle in the past was to generate MPC applications by hand. Recently, special compilers have been developed to build all kinds of applications. This book also explains in detail how efficient MPC applications can be created automatically from ANSI-C, thus, bridging the areas of cryptography, compilation and hardware synthesis. It also gives an insight into the requirements for creating efficient applications for MPC and is hence of interest to not only researchers in the area of MPC but also developers realizing practical applications with MPC. For a better understanding of the complete compile chain from ANSI-C to circuits, which is the ‘machine code’ of MPC, the authors first give the necessary background information on MPC protocols, Boolean logic, and logic synthesis. Then the authors describe the various compilation steps required to translate any code into an adequate circuit description. Afterwards, the authors introduce a variety of optimization techniques for two classes of MPC protocols, namely techniques that improve the runtime of applications in constant- and multi-round MPC protocols. The authors also illustrate how efficient parallelization of MPC protocols can be achieved using the assistance of compilers. It presents the effectiveness of the proposed techniques by giving a detailed evaluation on benchmarking applications. Most of the aforementioned techniques are implemented in our open source compiler that is accompanying this book and allows to study compilation for MPC in practice.Researchers who are interested in practical secure multi-party computation (MPC), and developers who are interested in realizing MPC applications in practice will find this book useful as a reference, as well as advanced-level students in computer science.

Emotions, especially those of impoverished migrant families, have long been underrepresented in German social and cultural studies. That Sinking Feeling raises the visibility of the emotional dimensions of exclusion processes and locates students in current social transformations. Drawing from a year of ethnographic fieldwork with grade ten students, Stefan Wellgraf’s study on an array of both classic emotions and affectively charged phenomena reveals a culture of devaluation and self-assertion of the youthful, post-migrant urban underclass in neoliberal times.
Search has been vital to artificial intelligence from the very beginning as a core technique in problem solving. The authors present a thorough overview of heuristic search with a balance of discussion between theoretical analysis and efficient implementation and application to real-world problems. Current developments in search such as pattern databases and search with efficient use of external memory and parallel processing units on main boards and graphics cards are detailed. Heuristic search as a problem solving tool is demonstrated in applications for puzzle solving, game playing, constraint satisfaction and machine learning. While no previous familiarity with heuristic search is necessary the reader should have a basic knowledge of algorithms, data structures, and calculus. Real-world case studies and chapter ending exercises help to create a full and realized picture of how search fits into the world of artificial intelligence and the one around us. - Provides real-world success stories and case studies for heuristic search algorithms - Includes many AI developments not yet covered in textbooks such as pattern databases, symbolic search, and parallel processing units
This book offers perspectives on how to develop a sustainable global balance of urbanization, land-use intensification, land abandonment, and multifunctional cultural landscapes. The focus is on the latter by describing the large variety of traditional cultural landscapes having evolved through centuries or even millennia by the use of the natural, terrestrial and aquatic resources. Those cultural landscapes encompass pasture, agroforestry, terraced, irrigation, coastal, monastic, and sacred landscapes as well as lake-, river-, and saltscapes. The restoration of low-input land-use systems which often carry a high biodiversity on the species, ecosystem, and landscape level as well as agrobiodiversity and agrodiversity is outlined. The restoration of multifunctional and diverse landscapes, however, is not only an ecological issue but encompasses many socio-economic aspects such as e.g., the revitalization of villages, eco-tourism, healthy food production, infrastructure, and rural-urban partnerships. Global environmental problems, which are related to urbanization and the intensification of the use of land and water resources are comprehensively outlined. Land abandonment which occurs on all continents is qualitatively and quantitatively assessed and the consequences for natural and cultural heritage loss is highlighted. With the presentation of current rural development and landscape conservation strategies on the national as well as international level, the topic reflects the high significance of environmental policy on the global scale. The global implementation of natural and cultural heritage conservation is, for example, given by the UNESCO World Heritage Sites, National Parks, Biosphere Reserves, Globally Important Agricultural Heritage Sites, High Nature Value Farmland, and the Satoyama initiative. However, also the “every-day” landscapes can contribute to biodiversity and strong sustainability. This comprehensive compendium, based on about 4,000 references of scientific studies, literature reviews, project reports, and environmental policy papers is thought for all students, scholars, and stakeholders from multifaceted disciplines, interested in multifunctional cultural landscapes and how traditions and innovation on the landscape level can be merged for a sustainable future on our planet. Case studies from all over the world are presented which can be used in Higher Education or to demonstrate the numerous approaches of sustainable rural development.
In this interdisciplinary textbook, which bridges the gap between the natural and social sciences both, the scientific principles of restoration ecology and practical aspects of ecosystem restoration are comprehensively presented. The diversity of land-use types with a focus on Central Europe is highlighted and case studies of practical restoration projects are presented. The textbook offers students who deal with the environment as well as scientists and practitioners a profound and up-to-date, but also critical overview of the state of knowledge. This book opens up the broad spectrum of degraded ecosystems of Central European natural and cultural landscapes. In further chapters, marine ecosystems and their restoration as well as development potentials and the limits of restoration are discussed in more detail. The ecological fundamentals are expanded through an interdisciplinary perspective taking into account environmental ethics, sociology, anthropology, and economics. In addition to an up-to-date overview of the various areas and fields of activity in restoration ecology and ecosystem restoration, the textbook provides a valuable basis for studies, science, and practice. The students also receive assistance in searching for literature and critical fact analysis, and the lecturers on teaching formats and interdisciplinary approaches to discussion in restoration ecology.
