The bib I iography includes papers in alI fields of photosynthesis researc- from studies of model biochemical and biophysical systems of the photosynthesis mechanism to primary production studied so-cal led growth analysis. In addition to papers devoted entirely to photosynthesis, papers on other topics are included if they contain data on photosynthetic activity, photorespiration, chloroplast structure, chlorophyl I and carotenoid synthesis and destruction, etc. , or if they contain valuable methodological information (measurement of selected environmental factors, leaf area, etc. ). In many branches it has been very difficult to define the I imits of interest for photosynthesis researchers. This problem has arisen e. g. in topics dealing with the transport of gases, where - in addition to the papers on C0 transfer- some papers on water vapour transfer are included, these 2 being of general application. On the other hand, many papers dealing with the anatomy and physiology of stomata have been omitted, if the aspect of carbon dioxide or water vapour exchange has not been discussed. To maximize the value of the bibliography the references are arranged alpha betically by author's names, and each volume is provided with three indexes. The authors' index to this volume contains alI names of authors, co-authors and editors. The subject index covers only primary items chosen according to their inter est for photosynthesis researchers. In this volume its preparation was based on the paper titles, key words and abstracts.
This book describes the evolution of the community development sector over the past 50 years, and it presents a framework and road map for how community development organizations can advance their mission through strategic partnerships that utilize their core competencies. The authors describe the current community development ecosystem, define a range of essential community development competencies, and demonstrate, through seven case studies, how using comparative advantages built on core competencies can improve outcomes for communities. By recognizing and leading with their competencies and strengths, organizations can bring their specialized areas of expertise to address complex and interconnected community challenges, and effectively meet their missions and objectives.
Preconditioning and the Conjugate Gradient Method in the Context of Solving PDEs is about the interplay between modeling, analysis, discretization, matrix computation, and model reduction. The authors link PDE analysis, functional analysis, and calculus of variations with matrix iterative computation using Krylov subspace methods and address the challenges that arise during formulation of the mathematical model through to efficient numerical solution of the algebraic problem. The book?s central concept, preconditioning of the conjugate gradient method, is traditionally developed algebraically using the preconditioned finite-dimensional algebraic system. In this text, however, preconditioning is connected to the PDE analysis, and the infinite-dimensional formulation of the conjugate gradient method and its discretization and preconditioning are linked together. This text challenges commonly held views, addresses widespread misunderstandings, and formulates thought-provoking open questions for further research.
Why should we study language? How do the ways in which we communicate define our identities? And how is this all changing in the digital world? Since 1993, many have turned to Language, Culture, and Society for answers to questions like those above because of its comprehensive coverage of all critical aspects of linguistic anthropology. This seventh edition carries on the legacy while addressing some of the newer pressing and exciting challenges of the 21st century, such as issues of language and power, language ideology, and linguistic diasporas. Chapters on gender, race, and class also examine how language helps create - and is created by - identity. New to this edition are enhanced and updated pedagogical features, such as learning objectives, updated resources for continued learning, and the inclusion of a glossary. There is also an expanded discussion of communication online and of social media outlets and how that universe is changing how we interact. The discussion on race and ethnicity has also been expanded to include Latin- and Asian-American English vernacular.

The work of writing closed captions for television and DVD is not simply transcribing dialogue, as one might assume at first, but consists largely of making rhetorical choices. For Sean Zdenek, when captioners describe a sound they are interpreting and creating contexts, they are assigning significance, they are creating meaning that doesn t necessarily exist in the soundtrack or the script. And in nine chapters he analyzes the numerous complex rhetorical choices captioners make, from abbreviating dialogue so it will fit on the screen and keep pace with the editing, to whether and how to describe background sounds, accents, or slurred speech, to nonlinguistic forms of sound communication such as sighing, screaming, or laughing, to describing music, captioned silences (as when a continuous noise suddenly stops), and sarcasm, surprise, and other forms of meaning associated with vocal tone. Throughout, he also looks at closed captioning style manuals and draws on interviews with professional captioners and hearing-impaired viewers. Threading through all this is the novel argument that closed captions can be viewed as texts worthy of rhetorical analysis and that this analysis can lead the entertainment industry to better standards and practices for closed captioning, thereby better serve the needs of hearing-impaired viewers. The author also looks ahead to the work yet to be done in bringing better captioning practices to videos on the Internet, where captioning can take on additional functions such as enhancing searchability. While scholarly work has been done on captioning from a legal perspective, from a historical perspective, and from a technical perspective, no one has ever done what Zdenek does here, and the original analytical models he offers are richly interdisciplinary, drawing on work from the fields of technical communication, rhetoric, media studies, and disability studies.
We cannot live a full life unless we know who we are, unless we know the essence of our being. The sciences, which have been immensely helpful in the way in which we live our lives, have been helpless when it comes to telling us how our life should be lived and what its meaning is. Accepting any philosophical or religious belief, on the other hand, limits our freedom to learn directly from personal knowledge of reality, as any preconceived ideas do not only alter its perception, but limit the spectrum of possibilities to which our reason can be applied. To those who do not surrender their right to decide for themselves what reality is, life offers a unique opportunity to apply their insights both in the worlds within and without and either validates or disproves their findings. If they are true to themselves, the continuous feeedback life offers will reveal to them unique characterics of our mind, which are otherwise limited by its own beliefs.
Describes the principles and history behind the use of Krylov subspace methods in science and engineering. The outcome of the analysis is very practical and indicates what can and cannot be expected from the use of Krylov subspace methods, challenging some common assumptions and justifications of standard approaches.
The authors have cleverly used exercises and their solutions to explore the concepts of multivariate data analysis. Broken down into three sections, this book has been structured to allow students in economics and finance to work their way through a well formulated exploration of this core topic. The first part of this book is devoted to graphical techniques. The second deals with multivariate random variables and presents the derivation of estimators and tests for various practical situations. The final section contains a wide variety of exercises in applied multivariate data analysis.
One of the most widespread problems in post-Communist countries is the quality of the judiciary. The book argues that these problems are intimately linked to the legal culture of Communist law, that an understanding of post-Communist judges necessarily requires an understanding of their Communist predecessors. There seems to be a deep continuity in the methods of legal reasoning employed by lawyers in the region of East Central Europe, starting in the era of Stalinism of the 1950s up to the current post-Communist period, which continuity is manifested in the problems of 1990s and 2000s. Communist legal culture and its aftermath provide an interesting analysis of the development of legal culture in a long-lasting system which was intellectually almost completely separated from the outside world. The book targets the judicial ideology, the conception of law, and the judicial self-perceptions, which are phenomena most likely to be contained in the deepest level of legal culture, that most resistant to change.
The vivid portratal of the "Velvet Revolution" describes the dramatic social and political changes that heralded the downfall of the Communist leadership in Czechoslavakia. Bernard Wheaton, one of the few Western observers in the country during the nonviolent change of government in November 1989, and Zdenek Kavan, himself a Czech, interweave firsthand description with interviews of student leaders, press accounts, and scholarly analysis of the historical antecedents of the revolution to bring the extraordinary events of 1989 to life. The authors also trace the evolution of change in Czechoslovakia, weighing the importance of the May 1990 elections and assessing political and social prospects for the future. The narrative is enriched with political cartoons and photographs.
The aim of the present volume was to give an overview over different available methodological approaches. The specialists may, perhaps, object that in their particular field the level of information is superficial. However, let them look at other chapters in which different approaches are discussed and which, surely, will appear less superficial from the more general point of view. We hope, at least, that crucial references can be traced throughout the book that would enable the readers to go in more detail when desired. It can be traced throughout the book that would enable the readers to go in more detail when desired. It was really one of our ideas to draw the survey of possibilities available. If this can stimulate the readers to use ideas to draw the survey of possibilities available. If this can stimulate the readers to use other methods that those they are routinely using the goals will be met.
The twentieth century has been a remarkable epoch in the affairs of men, and this is no less true of astronomy, at once the oldest and most modern of the sciences. Sky watchers at the beginning of the century measured positions and predicted celestial motions in faithful but uninspired homage to the Muse Urania; nowadays, their descendents call on all the resources of modern science to probe the nature and evolution of a bewildering range of celestial objects. Man has even set out to call personally on his nearest neighbours in space. Professor Zdenek Kopal has lived and practised astronomy throughout this efflorescence of his subject. Born in Czechoslovakia just before the outbreak of the Great War, and educated in the classical European tradition, he knows well the days when scholars commanded such respect that astronomical congresses would be visited by Heads of State. Yet within his own lifetime, he has himself been recruited to play an important role in scientific preparations for a manned Moon landing. He has known and worked with some of the most highly respected practitioners of Modern Astromomy: Russell, Shapley, Urey in the United States, Eddington in Britain. His fine eye for detail, coupled with his strong sense of history, enable him to unfold through his personal recollections the development of his subject across the social changes of two world wars. Inspired by his grandfather, who would think nothing of walking sixty miles to theatrical performance, the young Kopal acquired a Wanderlust that has taken him in his career more than a dozen times rond the world. He has visited the most ancient observatories, observed solar eclipses in Japan and Java, helped to establish new institutions in Iraq and India, and commuted for many years between the Old and New Worlds. He has toiled in every corner of his chosen vinyard: as observer, outstanding theoretician, populariser, editor and teacher. During his thirty years as Professor of Astronomy at Manchester, he
This book presents the state of art in the field of microbial zoonoses and sapronoses. It could be used as a textbook or manual in microbiology and medical zoology for students of human and veterinary medicine, including Ph.D. students, and for biomedicine scientists and medical practitioners and specialists as well. Surprisingly, severe zoonoses and sapronoses still appear that are either entirely new (e.g., SARS), newly recognized (Lyme borreliosis), resurging (West Nile fever in Europe), increasing in incidence (campylobacterosis), spatially expanding (West Nile fever in the Americas), with a changing range of hosts and/or vectors, with changing clinical manifestations or acquiring antibiotic resistance. The collective term for those diseases is (re)emerging infections, and most of them represent zoonoses and sapronoses (the rest are anthroponoses). The number of known zoonotic and sapronotic pathogens of humans is continually growing − over 800 today. In the introductory part, short characteristics are given of infectious and epidemic process, including the role of environmental factors, possibilities of their epidemiological surveillance, and control. Much emphasis is laid on ecological aspects of these diseases (haematophagous vectors and their life history; vertebrate hosts of zoonoses; habitats of the agents and their geographic distribution; natural focality of diseases). Particular zoonoses and sapronoses are then characterized in the following brief paragraphs: source of human infection; animal disease; transmission mode; human disease; epidemiology; diagnostics; therapy; geographic distribution.
The aim of the present book will be to provide a comprehensive account of our present knowledge of the theory of dynamical phenomena exhibited by elose binary systems; and on the basis of such phenomena as have been attested by available observations to outline probable evolutionary trends of such systems in the course of time. The evolution of the stars - motivated by nuelear as weIl as gravitation al energy sources - constitutes nowadays a well-established branch of stellar astronomy. No theo ries of such an evolution are as yet sufficently specific - let alone infallible - not to require continual tests by a confrontation of their consequences with the observed prop erties of actual stars at different stages of their evolution. The discriminating power of such tests depends, of course, on the range of information offered by the test objects. Single stars which move alone in space are now known to represent only a minority of objects constituting our Galaxy (cf. Chapter 1-2); and are, moreover, not very revealing of their basic physical characteristics - such as their masses or absolute dimensions. If there were no binary systems in the sky, the only star whose vital statistics would be fully known to us would be our Sun.
Eclipsing Variables - What They can Tell Us and What We can do with Them The aim of the present book will be to provide an introduction to the inter pretation of the observed light changes of eclipsing binary stars and their analysis for the elements of the respective systems. Whenever we study the properties of any celestial body - be it a planet or a star - all information we wish to gain can reach us through two different channels: their gravitational attraction, and their light. Gravitational interaction between our Earth and its celestial neighbours is, however, measurable only at distances of the order of the dimensions of our solar system; and the only means of communication with the realm of the stars are their nimble-footed photons reaching us - with appropriate time-lag - across the intervening gaps of space. As long as a star is single and emits constant light, it does not constitute a very revealing source of information. A spectrometry of its light can disclose, to be sure, the temperature (colour, or ionization) of the star's semi-transparent outer layers, their chemical composition, and prevalent pressure (through Stark effect) or magnetic field (Zeeman effect), it can disclose even some information about its absolute luminosity or rate of spin. It cannot, however, tell us anything about what we should like to know most - namely, the mass or size (i.e., density) of the respective configuration; its absolute dimensions, or its internal structure.
It has been nearly 150 years since Darwin published On the Origin of Species, and his theory of natural selection still ignites a forest of heated debate between scientific fundamentalists on the one hand and religious fundamentalists on the other. But both sides actually agree more than they disagree, and what has long been needed is a third way to view evolution, one that focuses more on the aspect of life and “being alive”, one that can guide us through, and perhaps out of, the fiery thicket. This book, a seminal work in the burgeoning field of Biosemiotics, provides that third way, by viewing living beings as genuine agents designing their communication pathways with, and in, the world. Already hailed as the best account of biological hermeneutics, Life As Its Own Designer: Darwin’s Origin and Western Thought is a wholly unique book divided into two parts. The first part is philosophical and explores the roots of rationality and the hermeneutics of the natural world with the overriding goal of discovering how narrative can help us to explain life. It analyzes why novelty is so hard to comprehend in the framework of Western thinking and confronts head-on the chasm between evolutionism and traditional rationalistic worldviews. The second part is scientific. It focuses on the life of living beings, treating them as co-creators of their world in the process of evolution. It draws on insights gleaned from the global activity of the Gaian biosphere, considers likeness as demonstrated on homology studies, and probes the problem of evo-devo science from the angle of life itself. This book is both timely and vital. Past attempts at a third way to view evolution have failed because they were written either by scientists who lacked a philosophical grounding or New Age thinkers who lacked biological credibility. Markoš and his coworkers form an original group of thinkers supremely capable in both fields, and they have fashioned a book that is ideal for researchers and scholars from both the humanities and sciences who are interested in the history and philosophy of biology, biosemiotics, and the evolution of life.
Quadratic programming (QP) is one advanced mathematical technique that allows for the optimization of a quadratic function in several variables in the presence of linear constraints. This book presents recently developed algorithms for solving large QP problems and focuses on algorithms which are, in a sense optimal, i.e., they can solve important classes of problems at a cost proportional to the number of unknowns. For each algorithm presented, the book details its classical predecessor, describes its drawbacks, introduces modifications that improve its performance, and demonstrates these improvements through numerical experiments. This self-contained monograph can serve as an introductory text on quadratic programming for graduate students and researchers. Additionally, since the solution of many nonlinear problems can be reduced to the solution of a sequence of QP problems, it can also be used as a convenient introduction to nonlinear programming.
ASTRONOMICAL ECLIPSE PHENOMENA In looking over the long history of human science from time immemorial to our own times, it is impossible to overestimate the role played in it by the phenomena of eclipses of the celestial bodies-both within our solar system as well as in the stellar universe at large. Not later than in the 4th century B. C. , the observed features of the shadow cast on the Moon by the Earth during eclipses led Aristotle (384-322 B. C. ) to formulate the first scientific proof worthy of that name of the spherical shape of the Earth; and only somewhat later, the eclipses of the Sun provided Aristarchos (in the early part of the 3rd century B. C. ) or Hipparchos (2nd half ofthe same century) with the geometric means to ascertain the distance which separates the Earth from the Sun. In the 17th century A. D. (in 1676, to be exact) the timings of the eclipses of the satellites of Jupiter by their central planet enabled Olaf Romer to discover that the velocity with which light propagates through space is finite.
