Tigris and Euphrates Rivers: Their Environment from Headwaters to Mouth (Aquatic Ecology Series #11)
by Laith A. JawadThe system of the Tigris-Euphrates Rivers is one of the great river systems of southwestern Asia. It comprises the Tigris and Euphrates Rivers, which follow roughly parallel courses through the heart of the Middle East. The lower portion of the region that they run through is known as Mesopotamia, was one of the cradles of civilisation. There are several environmental factors that govern the nature of the two rivers and shape the landscape the two rivers running through. Geological events create rivers, climate monitor the water supply, the surrounding land influences the vegetation and the physical and chemical features of water. The Tigris-Euphrates system runs through the territory of four countries, Iraq, Iran, Turkey and Syria. Therefore, any scientific approach to the environment of these two rivers should include the natural history events in these countries. The book "Tigris and Euphrates Rivers: Their Environment from Headwaters to Mouth" will be divided into nine parts. These parts deal with the issues of the environment, the status of the flora and fauna, the abiotic aspects, ecology, hydrological regime of the two rivers, the biotic aspects. Water resources, stress of the environment, conservation issues. Since the book of Julian Rzoska "Euphrates and Tigris Mesopotamian Ecology and Destiny" in 1980, no book or major reference has been published that includes between its cover the facts and information that the present book will present. Therefore, the importance of the present book falls in stating the present status of the environment of the two rivers and the comparison of their environment between now and that of 37 years ago as given by J. Rzoska (1980). The recent studies showed that there are a large number of natural and political events that happened within the last three decades in the area of the Tigris-Euphrates river system that for sure have done a great change to the environment of the two rivers and consequently changing the biological and non-biological resources of the two rivers. This book will be a reference book to both Academic and students across the Middle East in different disciplines of knowledge to use in their researches on Tigris-Euphrates river system. The scholars interested in this area will use this book as a guide to compare this freshwater system with other areas in Asia and the world.
Tikal
by David L. Lentz Nicholas P. Dunning Vernon L. Scarborough David L. Lentz Nicholas P. DunningThe primary theoretical question addressed in this book focuses on the lingering concern of how the ancient Maya in the northern Petén Basin were able to sustain large populations in the midst of a tropical forest environment during the Late Classic period. This book asks how agricultural intensification was achieved and how essential resources, such as water and forest products, were managed in both upland areas and seasonal wetlands, or bajos. All of these activities were essential components of an initially sustainable land use strategy that eventually failed to meet the demands of an escalating population. This spiraling disconnect with sound ecological principles undoubtedly contributed to the Maya collapse. The book's findings provide insights that broaden the understanding of the rise of social complexity - the expansion of the political economy, specifically - and, in general terms, the trajectory of cultural evolution of the ancient Maya civilization.

Tim Cook: The Genius Who Took Apple to the Next Level
by Leander KahneyJournalist Leander Kahney reveals how CEO Tim Cook has led Apple to astronomical success after the death of Steve Jobs in 2011. The death of Steve Jobs left a gaping void at one of the most innovative companies of all time. Jobs wasn't merely Apple's iconic founder and CEO; he was the living embodiment of a global megabrand. It was hard to imagine that anyone could fill his shoes--especially not Tim Cook, the intensely private executive who many thought of as Apple's "operations drone."But seven years later, as journalist Leander Kahney reveals in this definitive book, things at Apple couldn't be better. Its stock has nearly tripled, making it the world's first trillion dollar company. Under Cook's principled leadership, Apple is pushing hard into renewable energy, labor and environmentally-friendly supply chains, user privacy, and highly-recyclable products. From the massive growth of the iPhone to lesser-known victories like the Apple Watch, Cook is leading Apple to a new era of success.Drawing on access with several Apple insiders, Kahney tells the inspiring story of how one man attempted to replace someone irreplacable, and--through strong, humane leadership, supply chain savvy, and a commitment to his values--succeeded more than anyone had thought possible.
Timbre: Acoustics, Perception, and Cognition (Springer Handbook of Auditory Research #69)
by Kai Siedenburg Charalampos Saitis Stephen McAdams Arthur N. Popper Richard R. FayRoughly defined as any property other than pitch, duration, and loudness that allows two sounds to be distinguished, timbre is a foundational aspect of hearing. The remarkable ability of humans to recognize sound sources and events (e.g., glass breaking, a friend’s voice, a tone from a piano) stems primarily from a capacity to perceive and process differences in the timbre of sounds. Timbre raises many important issues in psychology and the cognitive sciences, musical acoustics, speech processing, medical engineering, and artificial intelligence. Current research on timbre perception unfolds along three main fronts: On the one hand, researchers explore the principal perceptual processes that orchestrate timbre processing, such as the structure of its perceptual representation, sound categorization and recognition, memory for timbre, and its ability to elicit rich semantic associations, as well as the underlying neural mechanisms. On the other hand, timbre is studied as part of specific scenarios, including the perception of the human voice, as a structuring force in music, as perceived with cochlear implants, and through its role in affecting sound quality and sound design. Finally, computational acoustic models are sought through prediction of psychophysical data, physiologically inspired representations, and audio analysis-synthesis techniques. Along these three scientific fronts, significant breakthroughs have been achieved during the last decade. This volume will be the first book dedicated to a comprehensive and authoritative presentation of timbre perception and cognition research and the acoustic modeling of timbre. The volume will serve as a natural complement to the SHAR volumes on the basic auditory parameters of Pitch edited by Plack, Oxenham, Popper, and Fay, and Loudness by Florentine, Popper, and Fay. Moreover, through the integration of complementary scientific methods ranging from signal processing to brain imaging, the book has the potential to leverage new interdisciplinary synergies in hearing science. For these reasons, the volume will be exceptionally valuable to various subfields of hearing science, including cognitive auditory neuroscience, psychoacoustics, music perception and cognition, but may even exert significant influence on fields such as musical acoustics, music information retrieval, and acoustic signal processing.It is expected that the volume will have broad appeal to psychologists, neuroscientists, and acousticians involved in research on auditory perception and cognition. Specifically, this book will have a strong impact on hearing researchers with interest in timbre and will serve as the key publication and up-to-date reference on timbre for graduate students, postdoctoral researchers, as well as established scholars.
Time: From Earth Rotation to Atomic Physics

Time and Chance
by David Z AlbertThis study is an attempt to get to the root of the tension between the best scientific pictures of the physical structure of the world and the everyday, empirical experience of it. It examines the problem of the direction of time - the notion that whatever can happen, can happen backwards.
Time and Chance
by David Z. ALBERTThis book is an attempt to get to the bottom of an acute and perennial tension between our best scientific pictures of the fundamental physical structure of the world and our everyday empirical experience of it. The trouble is about the direction of time. The situation (very briefly) is that it is a consequence of almost every one of those fundamental scientific pictures--and that it is at the same time radically at odds with our common sense--that whatever can happen can just as naturally happen backwards. Albert provides an unprecedentedly clear, lively, and systematic new account--in the context of a Newtonian-Mechanical picture of the world--of the ultimate origins of the statistical regularities we see around us, of the temporal irreversibility of the Second Law of Thermodynamics, of the asymmetries in our epistemic access to the past and the future, and of our conviction that by acting now we can affect the future but not the past. Then, in the final section of the book, he generalizes the Newtonian picture to the quantum-mechanical case and (most interestingly) suggests a very deep potential connection between the problem of the direction of time and the quantum-mechanical measurement problem. The book aims to be both an original contribution to the present scientific and philosophical understanding of these matters at the most advanced level, and something in the nature of an elementary textbook on the subject accessible to interested high-school students. Table of Contents: Preface 1. Time-Reversal Invariance 2. Thermodynamics 3. Statistical Mechanics 4. The Reversibility Objections and the Past-Hypothesis 5. The Scope of Thermodynamics 6. The Asymmetries of Knowledge and Intervention 7. Quantum Mechanics Appendix: Gedankenexperiments with Heat Engines Index Reviews of this book: The foundations of statistical mechanisms are often presented in physics textbooks in a rather obscure and confused way. By challenging common ways of thinking about this subject, Time and Chance can do quite a lot to improve this situation.--Jean Bricmont, ScienceAlbert is perfecting a style of foundational analysis that is uniquely his own...It has a surgical precision...and it is ruthless with pretensions. The foundations of thermodynamics is a topic that has accumulated a good deal of dead wood; this is a fire that will burn and burn.--Simon W. Saunders, Oxford UniversityAs usual with Albert's work, the exposition is brisk and to the point, and exceptionally clear...The book will be an extremely valuable contribution to the literature on the subject of philosophical issues in thermodynamics and statistical mechanics, a literature which has been thin on the ground but is now growing as it deserves to.--Lawrence Sklar, University of Michigan
Time and Complexity in Historical Ecology: Studies in the Neotropical Lowlands (Historical Ecology Series)
by William Balée Clark EricksonThis collection of studies by anthropologists, botanists, ecologists, and biologists is an important contribution to the emerging field of historical ecology. The book combines cutting-edge research with new perspectives to emphasize the close relationship between humans and their natural environment.Contributors examine how alterations in the natural world mirror human cultures, societies, and languages. Treating the landscape like a text, these researchers decipher patterns and meaning in the Ecuadorian Andes, Amazonia, the desert coast of Peru, and other regions in the neotropics. They show how local peoples have changed the landscape over time to fit their needs by managing and modifying species diversity, enhancing landscape heterogeneity, and controlling ecological disturbance. In turn, the environment itself becomes a form of architecture rich with historical and archaeological significance. Time and Complexity in Historical Ecology explores thousands of years of ecological history while also addressing important contemporary issues, such as biodiversity and genetic variation and change. Engagingly written and expertly researched, this book introduces and exemplifies a unique method for better understanding the link between humans and the biosphere.
Time and Economics: The Concept of Functional Time
by Željko RohatinskiThis book links the philosophical perception of time and Einstein’s theory of special relativity to economic processes, showing that the phenomena of time dilation and length contraction seen in physics can be identified within – and adapted to – an economic framework. The author expands on Marx’s model of reproduction with the additional variable of time, which is represented as a relative or functional category. In addition to allowing a more precise understanding of both static and dynamic relations between economic systems, this concept examines approaches to time proposed by Smith, Marshall and Keynes, and challenges the equilibrium and disequilibrium economic models. Rohatinski suggests that by understanding the differences in economic activity perceived across different time periods we are better able to influence that activity at micro- and macroeconomic levels.
Time and Its Adversaries in the Seleucid Empire
by Paul J. KosminUnder Seleucid rule, time no longer restarted with each new monarch. Instead, progressively numbered years, identical to the system we use today, became the measure of historical duration. Paul Kosmin shows how this invention of a new kind of time—and resistance to it—transformed the way we organize our thoughts about the past, present, and future.
Time and Literature (Cambridge Critical Concepts )
by Thomas M. AllenTime and Literature features twenty essays on topics from aesthetics and narratology to globalization and queer temporalities and showcases how time studies, often referred to as “the temporal turn,” cuts across and illuminates research in every field of literature, as well as interdisciplinary approaches drawing on history, philosophy, anthropology, and the natural sciences. Part I, “Origins,” addresses fundamental issues that can be traced back to the beginnings of literary criticism, while Part II, “Development,” shows how thinking about time has been crucial to various interpretive revolutions that have affected literary theory. Part III, “Application,” illustrates the centrality of temporal theorizing to literary criticism in a variety of contemporary approaches, from ecocriticism and new materialisms to media and archive studies. The first anthology to provide a synthesis of recent scholarship on the temporality of literary language from across different national and historical periods, Time and Literature will appeal to academic researchers and interested laypersons alike.
Time and Money: How Long and How Much Money is Needed to Regulate a Viable Economy
by Jean-Pierre AubinThis authored monograph presents an unconventional approach to an important topic in economic theory. The author is an expert in the field of viability theory and applies this theory to analyze how an economy should be dynamically endowed so that it is economically viable. Economic viability requires an assumption on the joint evolution of transactions, fluctuations of prices and units of numeraire goods: the sum of the "transactions values" and the "impact of price fluctuations" should be negative or equal to zero. The book presents a computation of the minimum endowment which restores economic viability and derives the dynamic laws that regulate both transactions and price fluctuations. The target audience primarily comprises open-minded and mathematically interested economists but the book may also be beneficial for graduate students.
