The amazing accuracy in verifying quantum effects experimentally has recently renewed interest in quantum mechanical measurement theory. In this book the authors give within the Hilbert space formulation of quantum mechanics a systematic exposition of the quantum theory of measurement. Their approach includes the concepts of unsharp objectification and of nonunitary transformations needed for a unifying description of various detailed investigations. The book addresses advanced students and researchers in physics and philosophy of science. In this second edition Chaps. II-IV have been substantially rewritten. In particular, an insolubility theorem for the objectification problem has been formulated in full generality, which includes unsharp object observables as well as unsharp pointers.
This report provides a framework for circular procurement and discusses its possibilities to promote circular economy. Several best practice examples in Denmark, Finland, Sweden and Norway illustrate how and in which sectors and product groups circular procurement could be applicable. Different approaches to circular procurement and tendering criteria supporting circular aspects are also illustrated.The study was carried out in Nordic co-operation by Finnish Environment Institute, IVL Swedish Environmental Research Institute and Copenhagen Resource Institute. The project was financed by the Nordic Council of Ministers (NCM), administrated by the NCM Sustainable Consumption and Production Working Group and guided by a steering group consisting representatives from Denmark, Finland, Iceland, Norway and Sweden.
Given recent controversies over suspected WMD programs in proliferating countries, there is an increasingly urgent need for effective monitoring and verification regimes—the international mechanisms, including on-site inspections, intended in part to clarify the status of WMD programs in suspected proliferators. Yet the strengths and limitations of these nonproliferation and arms control mechanisms remain unclear. How should these regimes best be implemented? What are the technological, political, and other limitations to these tools? What technologies and other innovations should be utilized to make these regimes most effective? How should recent developments, such as the 2015 Iran nuclear deal or Syria's declared renunciation and actual use of its chemical weapons, influence their architecture? The Politics of Weapons Inspections examines the successes, failures, and lessons that can be learned from WMD monitoring and verification regimes in order to help determine how best to maintain and strengthen these regimes in the future. In addition to examining these regimes' technological, political, and legal contexts, Nathan E. Busch and Joseph F. Pilat reevaluate the track record of monitoring and verification in the historical cases of South Africa, Libya, and Iraq; assess the prospects of using these mechanisms in verifying arms control and disarmament; and apply the lessons learned from these cases to contemporary controversies over suspected or confirmed programs in North Korea, Iran, and Syria. Finally, they provide a forward-looking set of policy recommendations for the future.
This project examines the market for recycled plastic, with a primary focus on post-consumer plastic waste because this is considered to be the more problematic. The market for plastic waste generated in manufacturing and production is relatively strong and well-functioning; As a consequence, the majority of plastic waste from manufacturing and production is recycled. Post-consumer waste is much less homogenous: it comes from a wide variety of sources, and contains a wide variety of plastics and tends to be difficult to collect, sort, and recycle. This project identifies barriers to further utilisation of recycled plastics, and analyses a collection of policy tools that could be used to support and expand that market.
Operational Quantum Physics offers a systematic presentation of quantum mechanics which makes exhaustive use of the full probabilistic structure of this theory. Accordingly the notion of an observable as a positive operator valued (POV) measure is explained in great detail, and the ensuing quantum measurement theory is developed and applied both to a resolution of long-standing conceptual and interpretational puzzles in the foundations of quantum mechanics, and to an analysis of various recent fundamental experiments. The book, or different parts of it, may be of interest to advanced students or researchers in quantum physics, to philosophers of physics, and to mathematicians working in operator valued measures.
Karl Barth' is an unparalleled accomplishment. An authentic church father of the Post-Reformation era, the Basel professor's contributions to theology, the life of the church, and the world of culture and politics have been frequently noted. This work, however, presents extraordinary new information and insight based on his own correspondence and notes. What one finds in this work is Barth's own running commentary on events and people - from 1886 to 1968. Everything is depicted from his perspective and chiefly in his own words, and this is precisely what makes the volume so fascinating and valuable. The brilliance, wit, and humanity of Barth shine through everywhere as he is seen as son, brother, student, editor, friend, pastor, husband, father, soldier, teacher, theologian, church leader, political critic, polemicist, ecumenist, author, preacher, music lover, senior citizen. The gigantic theologian is here, but - even more - the man shines through. An abundance of pictures accompanies the text - most of them to be seen for the first time. The contents of this book are new and of utmost interest and importance. Readers not familiar with the accomplishment of Karl Barth will learn to know both the man and his thought. Specialists will for the first time discern the figure behind the intellect. All who propose to understand the story of the twentieth century will be illumined by this book.
