Centring on South Africa's Hluhluwe-iMfolozi Park, this book synthesizes a century of insights from the ecology and conservation management of one of Africa's oldest protected wildlife areas. The park provides important lessons for conservation management, as it has maintained conservation values rivalling those of much larger parks sometimes through, and sometimes despite, strong management interventions, including the rescue of the white rhino from extinction. In addition, the book highlights the ecological science produced in the park, much of which has become widely influential, including the megaherbivore concept, new functional approaches to understanding biomes, and new understandings about the role of consumers in shaping ecosystems. The volume is ideal for researchers and policymakers interested in the conservation of relatively small, isolated and protected areas.

Franz Brentano (1838–1917) led an intellectual revolution that sought to revitalize German-language philosophy and to reverse its post-Kantian direction. His philosophy laid the groundwork for philosophy of science as it came to fruition in the Vienna Circle, and for phenomenology in the work of such figures as his student Edmund Husserl. This volume brings together newly commissioned chapters on his important work in theory of judgement, the reform of syllogistic logic, theory of intentionality, empirical descriptive psychology and phenomenology, theory of knowledge, metaphysics and ontology, value theory, and natural theology. It also offers a critical evaluation of Brentano's significance in his historical context, and of his impact on contemporary philosophy in both the analytic and the continental traditions.

Cancer is the second biggest killer in the world, but few of us understand how it works or how we treat it. In this illuminating introduction, Paul Scotting explains the science behind the disease and explores why some of us are more likely to develop it than others. Arguing that we're in a new age of understanding that will revolutionize the fight against cancer, Scotting discusses cutting-edge developments and maps out the promising future strategies for its prevention, treatment, and cure.

A captivating exploration of climate change, through the lens of nine different emotions, to better understand the science, history, and future of our changing planet. Dr Kate Marvel is a renowned climate scientist and researcher whose work on climate change led her to grapple with strong, complicated emotions. Initially, she resisted those feelings, afraid they would interfere with her objective scientific judgement.But over time she realised that there is no one way to think — or feel — about climate change. To live on and care for our changing planet, we need to embrace the full spectrum of human emotion. As Marvel argues, we need every emotion we can muster if we’re going to counter the usual myopic perspectives on climate change and care enough to make better decisions.And this book is a dazzling call to care. In Human Nature, each chapter uses a different emotion to illustrate the science behind our changing climate. We feel the wonder of being able to use climate models to predi

How science is opening up the mysteries of the heart, revealing the poetry in motion within the machine.Your heart is a miracle in motion, a marvel of construction unsurpassed by any human-made creation. It beats 100,000 times every day―if you were to live to 100, that would be more than 3 billion beats across your lifespan. Despite decades of effort in labs all over the world, we have not yet been able to replicate the heart’s perfect engineering. But, as Sian Harding shows us in The Exquisite Machine, new scientific developments are opening up the mysteries of the heart. And this explosion of new science―ultrafast imaging, gene editing, stem cells, artificial intelligence, and advanced sub-light microscopy―has crucial, real-world consequences for health and well-being. Harding―a world leader in cardiac research―explores the relation between the emotions and heart function, reporting that the heart not only responds to our emotions, it creates them as well. The condition known as Brok

The sulphate-reducing bacteria (SRB) are a large group of anaerobic organisms that play an important role in many biogeochemical processes. Not only are they of early origins in the development of the biosphere, but their mechanisms of energy metabolism shed light on the limits of life processes in the absence of oxygen. They are widely distributed in nature, and are regular components of engineered systems including, for example, petroleum reservoirs and oil production facilities. SRB are currently subject to extensive genomic studies, which are yielding fresh understanding of their basic biochemical mechanisms, and aiding in the development of novel techniques for the analyses of their environmental roles. This volume provides a timely update on these important microorganisms, from basic science to applications, and will therefore serve as a valuable resource for researchers and graduate students in the fields of microbial ecology, microbial physiology, bioengineering, biogeochemistr

A study of numerology in Elizabethan poetry, with some background studies which base the subject in classical learning, the works of Dante and Petrarch, and the esoteric traditions of the humanists. The central assumption of numerological criticism is that there exist works written in this tradition which show a correspondence between structure and meaning on a numerical plane; that is, one in which the number of the constituent parts (lines, stanzas, sonnets in a sequence) expresses a major aspect of the meaning. For instance parts of the whole can be arranged to represent months of the year and so on. Such structures of time and the triumphal form, in which the most important 'sovereign' element is placed at the centre, are the two main numerological patterns discussed by Dr Fowler. Critics have tended to regard numerology as an isolated phenomenon, rare after the Middle Ages but Dr Fowler demonstrates its persistence in the works of Spenser, Sidney, Chapman, Shakespeare, Donne, Jons

The twelfth-century borderlands of the duchy of Normandy formed the cockpit for dynastic rivalries between the kings of England and France. This 2004 book examines how the political divisions between Normandy and its neighbours shaped the communities of the Norman frontier. It traces the region's history from the conquest of Normandy in 1106 by Henry I of England, to the duchy's annexation in 1204 by the king of France, Philip Augustus, and its incorporation into the Capetian kingdom. It explores the impact of the frontier upon princely and ecclesiastical power structures, customary laws, and noble strategies such as marriage, patronage and suretyship. Particular attention is paid to the lesser aristocracy as well as the better known magnates, and an extended appendix reconstructs the genealogies of thirty-three prominent frontier lineages. The book sheds light upon the twelfth-century French aristocracy, and makes a significant contribution to our understanding of medieval political f

Drawing on a large volume of research, this 1998 book considers sustained warfare as a powerful agent of change which transformed a wide range of institutions, structures, and processes in Britain between 1688 and 1815, a period when Britain was at war for much of the time. Stressing the positive as well as the negative, and the long term as well as the short term, the effects of war are brought to bear upon questions of central importance in the study of eighteenth-century British history. How effectively did the emerging state cope with the financial and logistical demands of war? How severe were the economic and social strains imposed upon the population at large, and how did they respond to the call to arms? What effect did war have upon the industrialising economy? A balanced overview is presented of Britain as a nation at war during an important phase of her development as an imperial, industrial and military power.

The second book of Thucydides' history is of particular literary interest, containing as it does such important sections as the funeral oration, the account of the plague at Athens and the obituary of Pericles. Professor Rusten's commentary aims to assist the students to learn to read Thucydides. It scrutinises not only the standard historical context but also the literary and philosophical one, and devotes special attention to the exceptionally complex structures and techniques of language which make Thucydides the most difficult as well as most profound of ancient historians. The introduction surveys biographical interpretations of the text, suggests a new approach to fictive elements in the speeches, and sketches the chief features of Thucydidean style. This edition is intended primarily as a textbook for undergraduates and students in the upper forms of schools (both introduction and commentary are meant to be accessible even to less advanced students of Greek), but any Greek schol

This timely volume presents a synthesis of the ideas that emerged from a multidisciplinary colloquium held at the National Center for Atmospheric Research in August 1985. The aim was to assess the impact of drought as a major factor in the agrarian crisis in sub-Saharan Africa. Leading authorities engage in discussion of the African environment, the socio-political factors that generate famine, case studies of the effects of famine on these social structures, and finally possible lessons to be learnt on dealing with famine worldwide, thus developing an up-to-date and cohesive study of the problems of African development. Despite the current popular interest in the African famine problem, Drought and Hunger in Africa is the first major collection of the results that have emerged from the recent profusion of research relating to the subject. As such, this book has relevance, not only in Africa, but also to scientists, social-scientists and policy makers in the West, and to other areas of

The technological advances of contemporary society have outpaced our moral understanding of the problems that they create. How will we deal with profound ecological changes, human cloning, hybrid people, and eroding cyberprivacy, just to name a few issues? In this book, Lorenzo Magnani argues that existing moral constructs often cannot be applied to new technology. He proposes an entirely different ethical approach, one that blends epistemology with cognitive science. The resulting moral strategy promises renewed dignity for overlooked populations, both of today and of the future.

A unique guide to growing up perfectly weird and perfectly happy, by Dr Camilla Pang who was diagnosed with autism age 8 and was the youngest person and first writer of colour to win the Royal Society Science Book Prize for her book, Explaining Humans.FIND YOUR FEET. DISCOVER YOUR QUIRKS. GROW UP PERFECTLY WEIRD, PERFECTLY YOU.As a child Camilla loved patterns and putting things in order. She was obsessed with Stephen Hawking. And the only language she really understood was science. Diagnosed with autism age 8, Camilla saw the world very differently.But with science as her sidekick, she was able to translate ideas she could understand (like gravity, photosynthesis and algorithms) onto things she couldn't (like peer pressure, emotions and finding your voice).Today, Camilla is a scientist and an award-winning author, and she is here to share her scientific survival guide with you - so you can grow up with the courage to be yourself, no matter how different you feel or how tricky you migh

Einstein's general theory of relativity is widely considered to be one of the most elegant and successful scientific theories ever developed, and it is increasingly being taught in a simplified form at advanced undergraduate level within both physics and mathematics departments. Due to the increasing interest in gravitational physics, in both the academic and the public sphere, driven largely by widely-publicised developments such as the recent observations of gravitational waves, general relativity is also one of the most popular scientific topics pursued through self-study. Modern General Relativity introduces the reader to the general theory of relativity using an example-based approach, before describing some of its most important applications in cosmology and astrophysics, such as gamma-ray bursts, neutron stars, black holes, and gravitational waves. With hundreds of worked examples, explanatory boxes, and end-of-chapter problems, this textbook provides a solid foundation for unde

The atmosphere and ocean are two of the most important components of the climate system, and fluid dynamics is central to our understanding of both. This book provides a unified and comprehensive treatment of the field that blends classical results with modern interpretations. It takes the reader seamlessly from the basics to the frontiers of knowledge, from the equations of motion to modern theories of the general circulation of the atmosphere and ocean. These concepts are illustrated throughout the book with observations and numerical examples. As well as updating existing chapters, this full-color second edition includes new chapters on tropical dynamics, El Niño, the stratosphere and gravity waves. Supplementary resources are provided online, including figures from the book and problem sets, making this new edition an ideal resource for students in the atmospheric, oceanic and climate sciences, as well as in applied mathematics and engineering.

Given its brevity, Plato's Meno covers an astonishingly wide array of topics: politics, education, virtue, definition, philosophical method, mathematics, the nature and acquisition of knowledge and immortality. Its treatment of these, though profound, is tantalisingly short, leaving the reader with many unresolved questions. This book confronts the dialogue's many enigmas and attempts to solve them in a way that is both lucid and sympathetic to Plato's philosophy. Reading the dialogue as a whole, it explains how different arguments are related to one another and how the interplay between characters is connected to the philosophical content of the work. In a new departure, this book's exploration focuses primarily on the content and coherence of the dialogue in its own right and not merely in the context of other dialogues, making it required reading for all students of Plato, be they from the world of classics or philosophy.

This author provides an easily accessible introduction to quantum field theory via Feynman rules and calculations in particle physics. His aim is to make clear what the physical foundations of present-day field theory are, to clarify the physical content of Feynman rules. The book begins with a brief review of some aspects of Einstein's theory of relativity that are of particular importance for field theory, before going on to consider the relativistic quantum mechanics of free particles, interacting fields, and particles with spin. The techniques learnt in the chapters are then demonstrated in examples that might be encountered in real accelerator physics. Further chapters contain discussions of renormalization, massive and massless vector fields and unitarity. A final chapter presents concluding arguments concerning quantum electrodynamics. The book includes valuable appendices that review some essential mathematics, including complex spaces, matrices, the CBH equation, traces and di

From climate change to species extinction, humanity is confronted with an increasing array of societal and environmental challenges that defy simple quantifiable solutions. Complexity-based ecology provides a new paradigm for ecologists and conservationists keen to embrace the uncertainty that is pressed upon us. This book presents key research papers chosen by some sixty scholars from various continents, across a diverse span of sub-disciplines. The papers are set alongside first person commentary from many of the seminal voices involved, offering unprecedented access to experts' viewpoints.

With contributions from leaders and innovators from both academia and industry, this volume explores the discovery and application of optogenetics, from the basic science to its potential clinical use. Chapters cover a range of optogenetics applications, including for brain circuits, plasticity, memory, learning, sleep, vision and neurodegenerative and neuropsychiatric diseases. Providing authoritative coverage of the huge potential that optogenetics research carries, this is an ideal resource for researchers and graduate students, as well as for those working in the biotechnology and pharmaceutical industries and in a clinical setting.

What does it mean to be a citizen in a multicultural society? And what role must patriotism play in defining our relationship with our country and fellow citizens? In The Virtuous Citizen Tim Soutphommasane answers these questions with a critical defence of liberal nationalism. Considering a range of contemporary political debates from Europe, North America and Australia, over issues including multiculturalism, national history, civic education and immigration, Soutphommasane argues that a love of country should be valued alongside tolerance, mutual respect and public reasonableness as a civic virtue. A liberal form of patriotism, grounded in national identity, is, if anything, essential for political stability in a diverse society. This book is required reading not only for political theorists and philosophers but also for researchers and professionals in political science, sociology, history and public policy.

Despite the importance of commitment in moral and political philosophy, there has hitherto been little extended analysis of it. Marcel Lieberman examines the conditions under which commitment is possible, and offers at the same time an indirect argument for moral realism. He argues that realist evaluative beliefs are functionally required for commitment - especially regarding its role in self-understanding - and since it is only within a realist framework that such beliefs make sense, realism about values is a condition for the possibility of commitment itself. His ambitious study addresses questions that are of great interest to analytic philosophers but also makes many connections with continental philosophy and with folk psychology, sociology and cognitive science, and will be seen as a distinctive intervention in the debate about moral realism.

Corpus linguistics is the study of language data on a large scale - the computer-aided analysis of very extensive collections of transcribed utterances or written texts. This textbook outlines the basic methods of corpus linguistics, explains how the discipline of corpus linguistics developed and surveys the major approaches to the use of corpus data. It uses a broad range of examples to show how corpus data has led to methodological and theoretical innovation in linguistics in general. Clear and detailed explanations lay out the key issues of method and theory in contemporary corpus linguistics. A structured and coherent narrative links the historical development of the field to current topics in 'mainstream' linguistics. Practical tasks and questions for discussion at the end of each chapter encourage students to test their understanding of what they have read and an extensive glossary provides easy access to definitions of technical terms used in the text.

Resolution of the sixty-year debate over continental drift, culminating in the triumph of plate tectonics, changed the very fabric of Earth science. This four-volume treatise on the continental drift controversy is the first complete history of the origin, debate and gradual acceptance of this revolutionary theory. Based on extensive interviews, archival papers and original works, Frankel weaves together the lives and work of the scientists involved, producing an accessible narrative for scientists and non-scientists alike. Volume 1 covers the early 1900s when Wegener first proposed that the continents had once been a single landmass. Volume 2 describes the growing paleomagnetic case for continental drift in the 1950s and development of Apparent Polar Wander Paths. Volume 3 describes the expansion of the land-based paleomagnetic case for drifting continents, and Volume 4 recounts the discovery of geomagnetic reversals leading to the rapid acceptance of seafloor spreading and the birth
