Entrepreneurial alertness plays an important role in the processes of opportunity exploration and exploitation. A central thesis of this dissertation is that opportunity creation requires a certain transformation of an individual entrepreneur's mental schema. A four-dimension structure of the entrepreneurial alertness construct is created, namely juxtaposing, unlearning, prospecting and embellishing. A comprehensive model of entrepreneurial alertness are adopted and tested via structural equation modeling on the basis of survey data from 1080 entrepreneurs in two coastal regions of P. R. China.

This volume presents the first collection of work on research synthesis in applied linguistics. It introduces readers­ ­to a cutting-edge approach for reviewing and summarizing exactly what accumulated research has to say about theoretical and practical subjects. John Norris and Lourdes Ortega first elucidate the value and practice of synthesis, and they challenge all members of the research community to adopt a "synthetic ethic". The book then features seven empirical syntheses, each modeling rigorous synthetic practice in definitively reviewing the state of knowledge and research quality in important domains. Included are five meta-analyses on: Universal Grammar; Task-Based Interaction; Corrective Feedback; Instructed Pragmatics Development; and Reading Strategy Training. Also included are a qualitative meta-synthesis on Effective Teaching for English Language Learners, and a historiographical synthesis of Proficiency Assessment practices. Rounding out the collection are commentaries by two renowned experts in language learning and teaching research: Nick Ellis and Craig Chaudron.

This unique and encyclopedic reference work charts the evolution of the physics of shock waves and detonations from the earliest investigations into percussion and impact phenomena right up to the most recent groundbreaking research in the field. The history of this long and complex process is first reviewed in a general survey that encompasses everything from the earliest observations and interpretations of puzzling high-rate dynamic phenomena associated with natural and man-made explosions to a discussion of the merits of modern numerical computer simulations. The subject is then treated in more detail and in chronological order in the central section of the book, while also being richly illustrated in form of a picture gallery. The bibliographic index provides 122 short biographies of eminent researchers who have contributed to the field. Further references for biographical sources are given, and both name and subject indices (with over 4500 and 2700 entries, respectively) are provided. "This book is of tremendous value to all who teach, research or write about the subject or, simply, are inquisitive about the people whose names appear in the text or bibliographies. The whole community is indebted to Peter Krehl for what has clearly been a labour of love and for what must surely become the "bible" of shock waves, explosives and impact" Professor John E. Field, FRS, Cavendish Laboratory, University of Cambridge.

In this book the author presents two important findings revealed by high-precision magnetic penetration depth measurements in iron-based superconductors which exhibit high-transition temperature superconductivity up to 55 K: one is the fact that the superconducting gap structure in iron-based superconductors depends on a detailed electronic structure of individual materials, and the other is the first strong evidence for the presence of a quantum critical point (QCP) beneath the superconducting dome of iron-based superconductors. The magnetic penetration depth is a powerful probe to elucidate the superconducting gap structure which is intimately related to the pairing mechanism of superconductivity. The author discusses the possible gap structure of individual iron-based superconductors by comparing the gap structure obtained from the penetration depth measurements with theoretical predictions, indicating that the non-universal superconducting gap structure in iron-pnictides can be interpreted in the framework of A1g symmetry. This result imposes a strong constraint on the pairing mechanism of iron-based superconductors. The author also shows clear evidence for the quantum criticality inside the superconducting dome from the absolute zero-temperature penetration depth measurements as a function of chemical composition. A sharp peak of the penetration depth at a certain composition demonstrates pronounced quantum fluctuations associated with the QCP, which separates two distinct superconducting phases. This gives the first convincing signature of a second-order quantum phase transition deep inside the superconducting dome, which may address a key question on the general phase diagram of unconventional superconductivity in the vicinity of a QCP.
