本書是一部圍繞民俗學田野作業問題而展開的學術論爭，論爭焦點集中在“科學方法尤其是實驗方法是否適用于人文研究”的問題。全書分為上中下三編，上編是唇槍舌劍的“科玄論戰”，中編是實驗研究的學術案例，下編是執著於不同觀點的民俗學者就田野作業中科學與倫理問題而撰寫的學術論文。本書整理者旨在提倡一種實驗的田野研究觀：田野不能僅僅是個自然觀察的場所，也可以是我們實驗研究的場所。在田野中，除了會撿，還要會挖，除了

Increasingly, political scientists use the term 'experiment' or 'experimental' to describe their empirical research. One of the primary reasons for doing so is the advantage of experiments in establishing causal inferences. In this book, Rebecca B. Morton and Kenneth C. Williams discuss in detail how experiments and experimental reasoning with observational data can help researchers determine causality. They explore how control and random assignment mechanisms work, examining both the Rubin causal model and the formal theory approaches to causality. They also cover general topics in experimentation such as the history of experimentation in political science; internal and external validity of experimental research; types of experiments - field, laboratory, virtual, and survey - and how to choose, recruit, and motivate subjects in experiments. They investigate ethical issues in experimentation, the process of securing approval from institutional review boards for human subject research,

Why do some governments improve public services more effectively than others? Through the investigation of a new era of administrative reform, in which digital technologies may be used to facilitate citizens' access to the state, Jennifer Bussell's analysis provides unanticipated insights into this fundamental question. In contrast to factors such as economic development or electoral competition, this study highlights the importance of access to rents, which can dramatically shape the opportunities and threats of reform to political elites. Drawing on a sub-national analysis of twenty Indian states, a field experiment, statistical modeling, case studies, interviews of citizens, bureaucrats and politicians, and comparative data from South Africa and Brazil, Bussell shows that the extent to which politicians rely on income from petty and grand corruption is closely linked to variation in the timing, management and comprehensiveness of reforms.

Certain interactions, such as nuclear forces and the forces of 'high-energy' physics, which arise in the theory of elementary particles, cannot be described successfully by quantum field theory. Considerable interest has therefore centred on attempts to formulate interactions between elementary particles in terms of the S-Matrix, an operator introduced by Heisenberg which connects the input and output of a scattering experiment without seeking to give a localized description of the intervening events. In this book four authors, who are together responsible for many of these developments, set out a theory of the S-Matrix starting, as far as possible, from physically plausible assumptions and investigate the mathematical consequences. The least understood of these assumptions is the vital postulate of analyticity; much insight can however be gained into its working by a study of the Feyman integrals and the book describes what is known about their analytic and high energy properties.

Quantum physics allows entirely new forms of computation and cryptography, which could perform tasks currently impossible on classical devices, leading to an explosion of new algorithms, communications protocols and suggestions for physical implementations of all these ideas. As a result, quantum information has made the transition from an exotic research topic to part of mainstream undergraduate courses in physics. Based on years of teaching experience, this textbook builds from simple fundamental concepts to cover the essentials of the field. Aimed at physics undergraduate students with a basic background in quantum mechanics, it guides readers through theory and experiment, introducing all the central concepts without getting caught up in details. Worked examples and exercises make this useful as a self-study text for those who want a brief introduction before starting on more advanced books.

This is the first advanced, systematic and comprehensive look at weak decays in the framework of gauge theories. Included is a large spectrum of topics, both theoretical and experimental. In addition to explicit advanced calculations of Feynman diagrams and the study of renormalization group strong interaction effects in weak decays, the book is devoted to the Standard Model Effective Theory, dominating present phenomenology in this field, and to new physics models with the goal of searching for new particles and interactions through quantum fluctuations. This book will benefit theorists, experimental researchers, and Ph.D. students working on flavour physics and weak decays as well as physicists interested in physics beyond the Standard Model. In its concern for the search for new phenomena at short distance scales through the interplay between theory and experiment, this book constitutes a travel guide to physics far beyond the scales explored by the Large Hadron Collider at CERN.
