An in-depth study of population growth, examining the effects the increasing human population has on the natural world, as well as what people can do to promote conservation and develop a more sustainable lifestyle.At a time when environmental issues are being hotly debated, it is more important than ever that young people be fully informed. These titles invite advanced readers on a journey to explore the history of environmental affairs like never before. Each volume features a sophisticated design peppered with arresting photographs and relevant, compelling examples to clarify potentially complicated subjects. Multiple sidebars provide fodder for additional discussion and thought, and numerous resources are listed to encourage further interaction.

Laughter in Interaction is an illuminating and lively account of how and why people laugh during conversation. Bringing together twenty-five years of research on the sequential organisation of laughter in everyday talk, Glenn analyses recordings and transcripts to show the finely detailed co-ordination of human laughter. He demonstrates that its production and placement, relative to talk and other activities, reveal much about its emergent meaning and accomplishments. The book shows how the participants in a conversation move from a single laugh to laughing together, how the matter of 'who laughs first' implicates orientation to social activities and how interactants work out whether laughs are more affiliative or hostile. The final chapter examines the contribution of laughter to sequences of conversational intimacy and play and to the invocation of gender. Engaging and original, the book shows how this seemingly insignificant part of human communication turns out to play a highly sig

In this book, Michael Arbib, a researcher in artificial intelligence and brain theory, joins forces with Mary Hesse, a philosopher of science, to present an integrated account of how humans 'construct' reality through interaction with the social and physical world around them. The book is a major expansion of the Gifford Lectures delivered by the authors at the University of Edinburgh in the autumn of 1983. The authors reconcile a theory of the individual's construction of reality as a network of schemas 'in the head' with an account of the social construction of language, science, ideology and religion to provide an integrated schema-theoretic view of human knowledge. The authors still find scope for lively debate, particularly in their discussion of free will and of the reality of God. The book integrates an accessible exposition of background information with a cumulative marshalling of evidence to address fundamental questions concerning human action in the world and the nature of

Most previous research on human cognition has focused on problem-solving, and has confined its investigations to the laboratory. As a result, it has been difficult to account for complex mental processes and their place in culture and history. In this startling - indeed, disco in forting - study, Jean Lave moves the analysis of one particular form of cognitive activity, - arithmetic problem-solving - out of the laboratory into the domain of everyday life. In so doing, she shows how mathematics in the 'real world', like all thinking, is shaped by the dynamic encounter between the culturally endowed mind and its total context, a subtle interaction that shapes 1) Both tile human subject and the world within which it acts. The study is focused on mundane daily, activities, such as grocery shopping for 'best buys' in the supermarket, dieting, and so on. Innovative in its method, fascinating in its findings, the research is above all significant in its theoretical contributions. Have offers

An essential exploration of video game aesthetic that decenters the human player and challenges what it means to play.Do we play video games or do video games play us? Is nonhuman play a mere paradox or the future of gaming? And what do video games have to do with quantum theory? In Playing at a Distance, Sonia Fizek engages with these and many more daunting questions, forging new ways to think and talk about games and play that decenter the human player and explore a variety of play formats and practices that require surprisingly little human action. Idling in clicker games, wandering in walking simulators, automating gameplay with bots, or simply watching games rather than playing them―Fizek shows how these seemingly marginal cases are central to understanding how we play in the digital age. Introducing the concept of distance, Fizek reorients our view of computer-mediated play. To “play at a distance,” she says, is to delegate the immediate action to the machine and to become partic

The Complexity of Self Government represents a revolutionary approach to political science. Bottom-up theory turns political and social analysis upside down by focusing analytic attention not on vacuous abstractions but on the individual men and women who either consciously or inadvertently create the institutions within which they live. Understanding this practical level of human activity is made possible through complexity theory, recently developed in computer models, but of wider use in understanding everyday human behaviour. To this complexity framework, the book adds social science to give life and colour to the analytical picture: micro-sociology from Garfinkel and Goffman, anthropology from Bourdieu, and non-technical game theory based on Thomas Schelling's microanalytics, to give rigour and bite. Theoretical examples include India's Mumbai, Iran, the marshes of southern Iraq, Berlusconi's Italy, backcountry China, Zimbabwe, and Nelson Mandela's revolution in South Africa.

Human settlement of the western fringes of the Pacific began at least 40,000 years ago. Long, hazardous sea voyages were the only way of reaching the tiny islands scattered through this vast expanse of ocean. Food and shelter were hard to come by, even on land. This book, first published in 1996, documents how these settlers adapted culturally and biologically to the distinctive Pacific environment, and how they evolved into the large-bodied, muscular people seen today in New Zealand, Polynesia, Micronesia and Melanesia. Philip Houghton considers studies of DNA, patterns of health and disease, and computer simulations of human survival at sea based on the likely routes through the Pacific. People of the Great Ocean is a unique work based on extensive research and careful analysis. Philip Houghton's text presents detailed technical information, but remains highly readable and persuasive.

From the origins of writing to today's computer-mediated communication, material technologies shape how we read and write, how we construe and share knowledge, and ultimately how we understand ourselves in relation to the world. However, communication technologies are themselves designed in particular social and cultural contexts and their use is adapted in creative ways by individuals. In this book, Richard Kern explores how technology matters to language and the ways in which we use it. Kern reveals how material, social and individual resources interact in the design of textual meaning, and how that interaction plays out across contexts of communication, different situations of technological mediation, and different moments in time. Showing how people have adapted visual forms to various media as well as to social needs, this study culminates in five fundamental principles to guide language and literacy education in a period of rapid technological and social change.

Building up from microscopic basics to observed complex functions, this insightful monograph explains and describes how the unique molecular properties of water give rise to its structural and dynamical behaviour which in turn translates into its role in biological and chemical processes. The discussion of the biological functions of water details not only the stabilising effect of water in proteins and DNA, but also the direct role that water molecules themselves play in biochemical processes, such as enzyme kinetics, protein synthesis and drug-DNA interaction. The overview of the behaviour of water in chemical systems discusses hydrophilic, hydrophobic and amphiphilic effects, as well as the interactions of water with micelles, reverse micelles, microemulsions and carbon nanotubes. Supported by extensive experimental and computer simulation data, highlighting many of the recent advances in the study of water in complex systems, this is an ideal resource for anyone studying water at t

This up-to-date account of algebraic statistics and information geometry explores the emerging connections between the two disciplines, demonstrating how they can be used in design of experiments and how they benefit our understanding of statistical models, in particular, exponential models. This book presents a new way of approaching classical statistical problems and raises scientific questions that would never have been considered without the interaction of these two disciplines. Beginning with a brief introduction to each area, using simple illustrative examples, the book then proceeds with a collection of reviews and some new results written by leading researchers in their respective fields. Part III dwells in both classical and quantum information geometry, containing surveys of key results and new material. Finally, Part IV provides examples of the interplay between algebraic statistics and information geometry. Computer code and proofs are also available online, where key examp

This practical guide to survival data and its analysis for readers with a minimal background in statistics shows why the analytic methods work and how to effectively analyze and interpret epidemiologic and medical survival data with the help of modern computer systems. The introduction presents a review of a variety of statistical methods that are not only key elements of survival analysis but are also central to statistical analysis in general. Techniques such as statistical tests, transformations, confidence intervals, and analytic modeling are presented in the context of survival data but are, in fact, statistical tools that apply to understanding the analysis of many kinds of data. Similarly, discussions of such statistical concepts as bias, confounding, independence, and interaction are presented in the context of survival analysis and also are basic components of a broad range of applications. These topics make up essentially a 'second-year', one-semester biostatistics course in

The boreal forests of the world, geographically situated to the south of the Arctic and generally north of latitude 50 degrees, are considered to be one of the earth's most significant terrestrial ecosystems in terms of their potential for interaction with other global scale systems, such as climate and anthropologenic activity. This book, developed by an international panel of ecologists, provides a synthesis of the important patterns and processes which occur in boreal forests and reviews the principal mechanisms which control the forests' pattern in space and time. The effects of cold temperatures, soil ice, insects, plant competition, wildfires and climatic change on the boreal forests are discussed as a basis for the development of the first global scale computer model of the dynamical change of a biome, able to project the change of the boreal forest over timescales of decades to millennia, and over the global extent of this forest.

This book brings together contributions from researchers within various social science disciplines who seek to redefine the methods and topics that constitute the study of work. They investigate work activity in ways that do not reduce it to a 'psychology' of individual cognition nor to a 'sociology' of societal structures and communication. A key theme in the material is the relationship between theory and practice. This is not an abstract problem of interest merely to social scientists. Rather, it is discussed as an issue that working people address when they attempt to understand a task and communicate its demands. Mindful practices and communicative interaction are examined as situated issues at work in the reproduction of communities of practice in a variety of settings including: courts of law, computer software design, the piloting of airliners, the coordination of air traffic control, and traffic management in underground railway systems.

The interaction between computer and mathematics is becoming more and more important at all levels as computers become more sophisticated. This book shows how simple programs can be used to do significant mathematics. The purpose of this book is to give those with some mathematical background a wealth of material with which to appreciate both the power of the microcomputer and its relevance to the study of mathematics. The authors cover topics such as number theory, approximate solutions, differential equations and iterative processes, with each chapter self-contained. Many exercises and projects are included giving ready made material for demonstrating mathematical ideas. Only a fundamental knowledge of mathematics is assumed and programming is restricted to 'basic BASIC' which will be understood by any microcomputer. The book may be used as a textbook for algorithmic mathematics at several levels, with all the topics covered appearing in any undergraduate mathematics course.

Recent and ongoing developments in science and technology - such as the prevention and treatment of disease through genetics and the development of increasingly sophisticated computer systems with wide-ranging applications - hold out the promise of vastly improving the quality of human life, but they can also raise serious ethical, legal, and public policy questions. The thirteen essays in this volume address these questions and related issues from a variety of perspectives. Written by prominent philosophers, economists, and legal theorists, these essays offer valuable insights into the nature of scientific innovation and its implications for our social policies and practices.

Algorithms permeate our lives in numerous ways, performing tasks that until recently could only be carried out by humans. Artificial Intelligence (AI) technologies, based on machine learning algorithms and big-data-powered systems, can perform sophisticated tasks such as driving cars, analyzing medical data, and evaluating and executing complex financial transactions - often without active human control or supervision. Algorithms also play an important role in determining retail pricing, online advertising, loan qualification, and airport security. In this work, Martin Ebers and Susana Navas bring together a group of scholars and practitioners from across Europe and the US to analyze how this shift from human actors to computers presents both practical and conceptual challenges for legal and regulatory systems. This book should be read by anyone interested in the intersection between computer science and law, how the law can better regulate algorithmic design, and the legal ramificatio

Anthropological genetics is a field that has been in existence since the 1960s and has been growing within medical schools and academic departments, such as anthropology and human biology, ever since. With the recent developments in DNA and computer technologies, the field of anthropological genetics has been redefined. This volume deals with the molecular revolution and how DNA markers can provide insight into the processes of evolution, the mapping of genes for complex phenotypes and the reconstruction of the human diaspora. In addition to this, there are explanations of the technological developments and how they affect the fields of forensic anthropology and population studies, alongside the methods of field investigations and their contribution to anthropological genetics. This book brings together leading figures from the field to provide an introduction to anthropological genetics, aimed at advanced undergraduates to professionals, in genetics, biology, medicine and anthropology

a creative science picture book that combines STEAM education with the concept of “Creative Transformation”, turning everyday objects and waste into innovative, useful products. Through four real-life cases—transforming plastic waste into sustainable concrete, trash into solar-powered cars, hair into oil spill mats, and poop into energy—it shows how creativity paired with science can turn trash into treasure. The book also includes fun activities like "Science Showdown" (e.g. solar car VS fossil fuel car) and "DIY Science Experiments" (e.g. testing oil adsorption with human hair). These activities not only enrich knowledge and foster parent-child interaction but also inspire children to uncover the endless possibilities hidden in everyday life!

Conservation of biodiversity is best achieved through the management of natural communities, but progress in increasing our understanding of communities remains slow. The study of Antarctic communities can provide a valuable step forward in investigating the control of community development, the utilisation of habitats and the interaction between species in both species-rich and species-poor communities. This book contains chapters characterising the current approaches to both aquatic and terrestrial communities in the Antarctic. From biodiversity to trophic flows, from ecophysiological strategies to the impacts of environmental change and the effects of human disturbance, this volume provides an up-to-the-minute overview of community studies in an area covering ten per cent of the Earth's surface.

First published in 1983 this book provides a review of the fundamentals of the biology and mechanics of human skin. The major theme is the interaction between and dependence of the integrity of skin on, cell turnover, nutrition, control mechanisms and disease. Mechanical, thermal and electrical properties are presented separately in a way that should allow the mathematically inexperienced reader to understand the principles but with sufficient detail to permit development of more advanced ideas. Discussion of environmental effects on skin includes cosmetics, solar radiation and clinical treatments. An account of methods of wound closure and of the recent attempts to find a substitute for skin completes an overview of this fascinating tissue.

This 1995 volume views important social and political issues through the eyes of economists. Pioneered by Gary Becker, this approach asserts that all actions, whether working, playing, dating, or mating, have economic motivations and consequences, and can be analysed using economic reasoning. Intended as an introduction to the current state of the field, the essays are informal and non-technical, while still using up-to-date economic reasoning to illuminate such topics as crime, marriage, discrimination, immigration, fads and fashions. The expanding domain of economics is illustrated, as problems from sociology, political science, anthropology, and public policy are all included in this Beckerian view: the world of human interaction, as seen by an economist.

The Asian elephant has had a unique cultural association with people. Unfortunately, elephants and people have also been in conflict, resulting in the decline in elephants throughout their former range in Southern Asia. This book provides an ecological analysis of elephant-human interaction and its implication for the conservation of elephants. The foraging habits of elephants and their impact on vegetation are considered, along with the interactions that occur between elephants and humans. The ecological data provide the basis for recommendations on elephant conservation and management, keeping in view the socio-economic imperatives of the Asian region. This first comprehensive account of Asian elephant ecology will be of particular interest to conservation biologists and mammalogists.

Religion and Empire is an innovative and provocative study of the two largest states of the Precolumbian Americas, the Aztec and Inca Empires. By examining the causes of the formation and expansion of these two empires, the authors identify similar patterns and processes underlying their rise and decline. They demonstrate that in both examples among the critical elements in the transition from marginal people to imperial power to disintegrating society were changes in traditional religion, including the elaboration of Aztec human sacrifice and Inca worship of the corpses of their kings. The authors show that the complex interaction between such ideological shifts and political and economic factors generated the spectacular historical trajectories of these Pre-Colombian empires.

In the past, pandemics were considered divine punishment, but we now understand the biological characteristics of viruses and we know they are spread by social interaction and the movement of people. What used to be divine has become human - all too human, as Nietzsche would say.But while the virus dispels the divine, we are discovering that living beings are much more complex and harder to define than we had previously thought, and also discovering that the nature and exercise of political power are more complex than we may have thought. And this, argues Nancy, helps us to see why the term 'biopolitics' fails to grasp the conditions in which we now find ourselves. Life and politics challenge us together. Our scientific knowledge tells us that we are dependent only on our own technical power, but can we rely on technologies when knowledge itself includes uncertainties? If this is the case for technical power, it is much more so for political power, even as it presents itself as guided

This book is about animals and humans - their common features and their gradual and principle differences. It tells of democracy in baboons, prostitution in hummingbirds, bigamy in wrens, baby sitting in jackals, of chimpanzees at the computer console and of the super-ego of dogs - but it is also about the labour productivity of hunter and gatherer peoples, incest avoidance in animals and humans and of the myths about matriarchy. In a language accessible to any interested layman, Georg Breuer, gives a balanced account of the main ideas and achievements of sociobiology and the main criticisms levelled against it. According to him sociobiology has given many a valuable impetus but sometimes presents a distorted or one-sided view. In particular it has not answered or addressed the question of why man, and man only, is able to identify and feel sympathy with any other human being. The evolution of this most human of all traits confers on us the capability for charity and solidarity and for

Is British English becoming more like American English? If so, why, and in what ways? This book compares examples of American and British language data from the 1930s, 1960s, 1990s and 2000s, to track the most important ways that both varieties are changing over time, and compares the extent to which they are following similar paths using a mixture of computer and human analysis. The analysis is carried out across several levels, including spelling differences (such as colour vs color), vocabulary (truck vs lorry), and a range of morphological, grammatical, semantic and pragmatic features. Baker explores the changing aspects of American and British society which help to explain the findings.

Surnames are inherited in much the same way as are biological traits. Since surnames were generally adopted - in Europe during Medieval times - their distribution has become very uneven: analysis of the present geographic patterns provides an insight into the kind of redistribution of genes that has resulted from all the migrations of the intervening years. Using non-technical language and a minimum of mathematics, this book presents a lucid description and evaluation of these studies of the genetic structure of human populations. A special feature is the appendix which presents computer-generated maps and distribution diagrams of 100 common surnames in England and Wales.

Robert O'Brien loves cars. Growing up in Dublin, they provided a welcome refuge from the human interaction he found so difficult. His father's M3 became his alterego - powerful, admired, confident-and Robert began a quest to become a worthy owner. He completed a university degree, took courses to conquer his stammer and tried to come to terms with his sexuality. But still he remained more comfortable in the fantasy worlds of video games, television and the closet. Inspired to pursue an acting career, he moved from Ireland to Vancouver in search of sci-fi stardom, liberation and himself. After years of struggle and therapy, he is now proud of the man he is and no longer believes he needs to be fixed.
