Theories and Methods for Minimizing Cadmium Pollution in Crops: Case Studies on Water Spinach
by Zhongyi Yang Chuntao He Junliang XinThe cadmium (Cd) contamination has raised increasingly global concern on food safety. The book was composed to bring comprehensive and valuable thoughts about the food safety management against heavy metal contamination. In this book, current status of cadmium contamination in agricultural soils and crops is systematically summarized. In order to reduce the risk of Cd pollution in crops, Cd pollution-safe cultivar (Cd-PSC) strategy, i.e. identifying, breeding and applying the cultivars with particularly low Cd accumulation capacity in edible parts even when grown in Cd contaminated soil, is proposed as a most effective, low-cost and environmental-friendly method for minimizing Cd pollution in crops. To describe the framework of the Cd-PSC strategy, a series research results on water spinach (Ipomoea aquatica Forsk) are summarized as a typical case. The latest findings about the Cd-PSCs of water spinach, including cultivar variation in shoot Cd accumulation, identification and verification of low- and high-Cd accumulating cultivars, stability of Cd accumulation capacity at the cultivar level, biochemical and molecular mechanisms of the cultivar-dependent Cd uptake, transfer and accumulation, breeding methods for improving Cd-PSCs, and so on, have been covered. This book will provide valuable theoretical and practical understandings for controlling Cd pollution in crops grown on agricultural soils with known or unknown risk of Cd contamination.
Theories in Ecological Risk Assessment (Theoretical Biology)
by Masashi KamoThis book introduces various mathematical models used in ecological risk assessment, primarily discussing models used in hazard assessment. The book aims to link ecology and conservation biology with risk assessments, bringing together the knowledge of ecotoxicology and ecology for effective risk assessment. The first part describes population-level assessment in ecological risk assessment. The chapters cover current methodologies for ecological risk assessment, individual-level assessment, population dynamics models for population-level assessment, case studies, mathematical models for population extinctions, the derivation of mean time to extinction (MTE) and their case studies. The second part of the book discusses the mathematical models involved in hazard assessments. It introduces the method of risk assessment using species sensitivity distributions (SSDs), hazard assessment of metals, chemical mixtures using the Michaelis-Menten equation, basic elements of statistics and related topics. Expected readers are risk assessors in governments and public sectors, students and young researchers interested in environmental science. The book is made accessible and easy to follow by beginners in mathematical biology and theoretical ecology.

Theories of Hypnosis: Current Models and Perspectives
by Steven J. Lynn Judith W. RhueA survey of current theories of hypnosis along with relevant research.
Theories of Illness: World Survey
by George Peter MurdockTheories of Illness establishes a new landmark in comparative studies. Utilizing concepts from modern medicine and anthropological theory, Professor Murdock distinguishes the natural causes of illness from theories of supernatural causation. He subdivides the latter into theories of illness that are related to aggression (witchcraft, sorcery, and spirit aggression) and those which are related to guilt and a sense of sin (taboo violation and mystical retribution). Obviously, these relate to man's most basic beliefs as revealed in early religions.
Theories of Information, Communication and Knowledge: A Multidisciplinary Approach
by Thomas M Dousa Fidelia Ibekwe-SanjuanThis book addresses some of the key questions that scientists have been asking themselves for centuries: what is knowledge? What is information? How do we know that we know something? How do we construct meaning from the perceptions of things? Although no consensus exists on a common definition of the concepts of information and communication, few can reject the hypothesis that information - whether perceived as « object » or as « process » - is a pre-condition for knowledge. Epistemology is the study of how we know things (anglophone meaning) or the study of how scientific knowledge is arrived at and validated (francophone conception). To adopt an epistemological stance is to commit oneself to render an account of what constitutes knowledge or in procedural terms, to render an account of when one can claim to know something. An epistemological theory imposes constraints on the interpretation of human cognitive interaction with the world. It goes without saying that different epistemological theories will have more or less restrictive criteria to distinguish what constitutes knowledge from what is not. If information is a pre-condition for knowledge acquisition, giving an account of how knowledge is acquired should impact our comprehension of information and communication as concepts. While a lot has been written on the definition of these concepts, less research has attempted to establish explicit links between differing theoretical conceptions of these concepts and the underlying epistemological stances. This is what this volume attempts to do. It offers a multidisciplinary exploration of information and communication as perceived in different disciplines and how those perceptions affect theories of knowledge.
Theories of Population Variation in Genes and Genomes (Princeton Series in Theoretical and Computational Biology #4)
by Freddy Bugge ChristiansenThis textbook provides an authoritative introduction to both classical and coalescent approaches to population genetics. Written for graduate students and advanced undergraduates by one of the world's leading authorities in the field, the book focuses on the theoretical background of population genetics, while emphasizing the close interplay between theory and empiricism. Traditional topics such as genetic and phenotypic variation, mutation, migration, and linkage are covered and advanced by contemporary coalescent theory, which describes the genealogy of genes in a population, ultimately connecting them to a single common ancestor. Effects of selection, particularly genomic effects, are discussed with reference to molecular genetic variation. The book is designed for students of population genetics, bioinformatics, evolutionary biology, molecular evolution, and theoretical biology--as well as biologists, molecular biologists, breeders, biomathematicians, and biostatisticians. Contains up-to-date treatment of key areas in classical and modern theoretical population genetics Provides in-depth coverage of coalescent theory Discusses genomic effects of selection Gives examples from empirical population genetics Incorporates figures, diagrams, and boxed features throughout Includes end-of-chapter exercises Speaks to a wide range of students in biology, bioinformatics, and biostatistics
Theories of the World from Antiquity to the Copernican Revolution: Second Revised Edition
by Michael J. CroweThis newly revised edition of Professor Crowe's accessible and enlightening book recreates one of the most dramatic developments in the history of thought: the change from an earth-centered to a sun-centered conception of the solar system. Written in a clear and straightforward manner, the work is organized around a hypothetical debate: Given the evidence available in 1615, which planetary system (Ptolemaic, Copernican, Tychonic, etc.) was most deserving of support?Beginning with an introductory chapter on celestial motions, Dr. Crowe proceeds to a discussion of Greek astronomy before Ptolemy, mathematical techniques used by ancient astronomers, the Ptolemaic system, the Copernican and Tychonic systems, and the contributions of Kepler and Galileo. In an epilogue, quotes from writers, philosophers, and scientists reveal the impact of Copernican thought on their work. Easily within the reach of anyone with a background in high school mathematics, this absorbing study offers a sound introduction to our solar system and an opportunity to relive one of the most momentous periods in intellectual history.
Theorizing Outdoor Recreation and Ecology (Leisure Studies in a Global Era)
by Sean RyanDeciding what user impacts are natural or unnatural has inspired much debate. Biophysically, moose cause similar kinds of soil and vegetation impacts as hikers. Yet moose are the sign of nature while hikers are the sign of damage. The field of outdoor recreation is beset with paradoxes, and this book presents a unique, alternative framework to address these dilemmas. Examining outdoor recreation through the lens of ecological theory, Ryan draws from theorists such as Foucault, Derrida and Latour. The book explores minimum impact strategies designed to protect and enhance ecological integrity, but that also require a disturbing amount of policing of users, which runs counter to the freedom users seek. Recent ecological theory suggests that outdoor recreation's view of nature as balanced when impacts are removed is outdated and incorrect. What is needed, and indeed Ryan presents, is a paradoxical and ecological view of humans as neither natural nor unnatural, a view that embraces some traces in nature.
Theorizing the Future of Science Education Research (Contemporary Trends and Issues in Science Education #49)
by Brian Hand Vaughan PrainThis book reviews the current state of theoretical accounts of the what and how of science learning in schools. The book starts out by presenting big-picture perspectives on key issues. In these first chapters, it focuses on the range of resources students need to acquire and refine to become successful learners. It examines meaningful learner purposes and processes for doing science, and structural supports to optimize cognitive engagement and success. Subsequent chapters address how particular purposes, resources and experiences can be conceptualized as the basis to understand current practices. They also show how future learning opportunities should be designed, lived and reviewed to promote student engagement/learning. Specific topics include insights from neuro-imaging, actor-network theory, the role of reasoning in claim-making for learning in science, and development of disciplinary literacies, including writing and multi-modal meaning-making. All together the book offers leads to science educators on theoretical perspectives that have yielded valuable insights into science learning. In addition, it proposes new agendas to guide future practices and research in this subject.
Theory Choice in the History of Chemical Practices
by Emma Tobin Chiara AmbrosioThis collection of essays examines the question of theory from the perspective of the history of chemistry. Through the lens of a number of different periods, the authors provide a historical analysis of the question of theory in the history of chemical practice. The consensus picture that emerges is that the history of science tells us a much more complex story about theory choice. A glimpse at scientific practice at the time shows that different, competing as well as non-competing, theories were used in the context of the scientific practice at the various times and sometimes played a pivotal pedagogical role in training the next generation of chemists. This brief brings together a history of chemical practice, and in so doing reveals that theory choice is conceptually more problematic than was originally conceived. This volume was produced as part of the Ad HOC chemistry research group hosted by University College London and University of Cambridge.

Theory Of Quantum Liquids
by Philippe Nozieres David PinesCombines a two-volume graduate textbook for students with a knowledge of elementary quantum mechanics and statistical physics. Nozires (statistical physics, College of France, Paris) and Pines (physics, U. of Illinois-Urbana-Champaign) delayed the second volume for over two decades waiting for new findings, then decided to publish the original piece. The first, published in 1966, was subtitled Normal Fermi Liquids and deals with Landau's theory on those, its applications to various fluids and electrons in metals, elementary excitation, response functions, and other topics. The second volume, published in 1990 without a subtitle, treats Bose condensation , the development of Bose liquid theory, a microscopic basis for the two-fluid model and the elementary excitations of liquid helium II.
