An accessible synthesis of ethical issues raised by artificial intelligence that moves beyond hype and nightmare scenarios to address concrete questions.Artificial intelligence powers Google''s search engine, enables Facebook to target advertising, and allows Alexa and Siri to do their jobs. AI is also behind self-driving cars, predictive policing, and autonomous weapons that can kill without human intervention. These and other AI applications raise complex ethical issues that are the subject of ongoing debate. This volume in the MIT Press Essential Knowledge series offers an accessible synthesis of these issues. Written by a philosopher of technology, AI Ethics goes beyond the usual hype and nightmare scenarios to address concrete questions.Mark Coeckelbergh describes influential AI narratives, ranging from Frankenstein''s monster to transhumanism and the technological singularity. He surveys relevant philosophical discussions: questions about the fundamental differences between humans and machines and debates over the moral status of AI. He explains the technology of AI, describing different approaches and focusing on machine learning and data science. He offers an overview of important ethical issues, including privacy concerns, responsibility and the delegation of decision making, transparency, and bias as it arises at all stages of data science processes. He also considers the future of work in an AI economy. Finally, he analyzes a range of policy proposals and discusses challenges for policymakers. He argues for ethical practices that embed values in design, translate democratic values into practices and include a vision of the good life and the good society.

Are we alone in the universe? If not, where is everybody? An engaging exploration of one of the most important unsolved problems in science.Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity—but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox—and finding extraterrestrials.

The development, manufacturing, and use of contraceptive methods from the late nineteenth century to the present, viewed from the perspective of reproductive justice.The beginning of the modern contraceptive era began in 1882, when Dr. Aletta Jacobs opened the first birth control clinic in Amsterdam. The founding of this facility, and the clinical provision of contraception that it enabled, marked the moment when physicians started to take the prevention of pregnancy seriously as a medical concern. In this volume in the MIT Press Essential Knowledge series, Donna Drucker traces the history of modern contraception, outlining the development, manufacturing, and use of contraceptive methods from the opening of Dr. Jacobs's clinic to the present. Drucker approaches the subject from the perspective of reproductive justice: the right to have a child, the right not to have a child, and the right to parent children safely and healthily.Drucker describes contraceptive methods available before the pill, including the diaphragm (dispensed at the Jacobs clinic) and condom, spermicidal jellies, and periodic abstinences. She looks at the development and dissemination of the pill and its chemical descendants; describes technological developments in such non-hormonal contraceptives as the cervical cap and timing methods (including the "rhythm method” favored by the Roman Catholic church); and explains the concept of reproductive justice. Finally, Drucker considers the future of contraception—the adaptations of existing methods, new forms of distribution, and ongoing efforts needed to support contraceptive access worldwide.

An introduction to computational thinking that traces a genealogy beginning centuries before the digital computer.A few decades into the digital era, scientists discovered that thinking in terms of computation made possible an entirely new way of organizing scientific investigation; eventually, every field had a computational branch: computational physics, computational biology, computational sociology. More recently, "computational thinking” has become part of the K-12 curriculum. But what is computational thinking? This volume in the MIT Press Essential Knowledge series offers an accessible overview, tracing a genealogy that begins centuries before digital computers and portraying computational thinking as pioneers of computing have described it. The authors explain that computational thinking (CT) is not a set of concepts for programming; it is a way of thinking that is honed through practice: the mental skills for designing computations to do jobs for us, and for explaining and interpreting the world as a complex of information processes. Mathematically trained experts (known as "computers”) who performed complex calculations as teams engaged in CT long before electronic computers. The authors identify six dimensions of today's highly developed CT—methods, machines, computing education, software engineering, computational science, and design—and cover each in a chapter. Along the way, they debunk inflated claims for CT and computation while making clear the power of CT in all its complexity and multiplicity.

Taking "Gangnam Style” seriously: what Internet memes can tell us about digital culture.In December 2012, the exuberant video "Gangnam Style” became the first YouTube clip to be viewed more than one billion times. Thousands of its viewers responded by creating and posting their own variations of the video—"Mitt Romney Style,” "NASA Johnson Style,” "Egyptian Style,” and many others. "Gangnam Style” (and its attendant parodies, imitations, and derivations) is one of the most famous examples of an Internet meme: a piece of digital content that spreads quickly around the web in various iterations and becomes a shared cultural experience. In this book, Limor Shifman investigates Internet memes and what they tell us about digital culture. Shifman discusses a series of well-known Internet memes—including "Leave Britney Alone,” the pepper-spraying cop, LOLCats, Scumbag Steve, and Occupy Wall Street's "We Are the 99 Percent.” She offers a novel definition of Internet memes: digital content units with common characteristics, created with awareness of each other, and circulated, imitated, and transformed via the Internet by many users. She differentiates memes from virals; analyzes what makes memes and virals successful; describes popular meme genres; discusses memes as new modes of political participation in democratic and nondemocratic regimes; and examines memes as agents of globalization. Memes, Shifman argues, encapsulate some of the most fundamental aspects of the Internet in general and of the participatory Web 2.0 culture in particular. Internet memes may be entertaining, but in this book Limor Shifman makes a compelling argument for taking them seriously.

A concise overview of fertility technology-its history, practical applications, and ethical and social implications around the world.In the late 1850s, a physician in New York City used a syringe and glass tube to inject half a drop of sperm into a woman's uterus, marking the first recorded instance of artificial insemination. From that day forward, doctors and scientists have turned to technology in ever more innovative ways to facilitate conception. Fertility Technology surveys this history in all its medical, practical, and ethical complexity, and offers a look at state-of-the-art fertility technology in various social and political contexts around the world.Donna J. Drucker's concise and eminently readable account introduces the five principal types of fertility technologies used in human reproduction-artificial insemination; ovulation timing; sperm, egg, and embryo freezing; in vitro fertilization; and IVF in uterine transplants-discussing the development, manufacture, dispersion, and use of each. Geographically, it focuses on countries where innovations have emerged and countries where these technologies most profoundly affect individuals and population policies. Drucker's wide-ranging perspective reveals how these technologies, used for birth control as well as conception in many cases, have been critical in shaping the moral, practical, and political meaning of human life, kinship, and family in different nations and cultures since the mid-nineteenth century.

The socially constructed phenomenon of whiteness: how it was created, how it changes, and how it protects and privileges people who are perceived as white.This volume in the MIT Press Essential Knowledge series examines the socially constructed phenomenon of whiteness, tracing its creation, its changing formation, and its power to privilege and protect people who are perceived as white. Whiteness, author Martin Lund explains, is not one single idea but a shifting, overarching category, a flexible cluster of historically, culturally, and geographically contingent ideals and standards that enable systems of hierarchical classification. Lund discusses words used to talk about whiteness, from white privilege to white fragility; the intersections of whiteness with race, class, and gender; whiteness in popular culture; and such ideas as "e;colorblindness"e; and "e;reverse racism,"e; which, he argues, actually uphold whiteness.Lund shows why it is important to keep talking and thinking about whiteness. The word "e;whiteness,"e; he writes, doesn't describe; it conjures something into being. Drawing on decades of critical whiteness studies and citing a range of examples (primarily from the United States and Sweden), Lund argues that whiteness is continually manufactured and sustained through language, laws, policies, science, and representations in media and popular culture. It is often positioned as normative, even universal. And despite its innocuous-seeming manifestations in sitcoms and superheroes, whiteness is always in the service of racial domination.

Key concepts, definitions, examples, and historical contexts for understanding smart cities, along with discussions of both drawbacks and benefits of this approach to urban problems.Over the past ten years, urban planners, technology companies, and governments have promoted smart cities with a somewhat utopian vision of urban life made knowable and manageable through data collection and analysis. Emerging smart cities have become both crucibles and showrooms for the practical application of the Internet of Things, cloud computing, and the integration of big data into everyday life. Are smart cities optimized, sustainable, digitally networked solutions to urban problems? Or are they neoliberal, corporate-controlled, undemocratic non-places? This volume in the MIT Press Essential Knowledge series offers a concise introduction to smart cities, presenting key concepts, definitions, examples, and historical contexts, along with discussions of both the drawbacks and the benefits of this approach to urban life.After reviewing current terminology and justifications employed by technology designers, journalists, and researchers, the book describes three models for smart city development—smart-from-the-start cities, retrofitted cities, and social cities—and offers examples of each. It covers technologies and methods, including sensors, public wi-fi, big data, and smartphone apps, and discusses how developers conceive of interactions among the built environment, technological and urban infrastructures, citizens, and citizen engagement. Throughout, the author—who has studied smart cities around the world—argues that smart city developers should work more closely with local communities, recognizing their preexisting relationship to urban place and realizing the limits of technological fixes. Smartness is a means to an end: improving the quality of urban life.

An accessible guide to the ideas and technologies underlying such applications as GPS, Google Maps, Pokemon Go, ride-sharing, driverless cars, and drone surveillance.

An exploration of quantum entanglement and the ways in which it contradicts our everyday assumptions about the ultimate nature of reality.Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement—called by Einstein "spooky action at a distance”—rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying? In this volume in the MIT Press Essential Knowledge series, Jed Brody equips readers to decide for themselves. He explains how our commonsense assumptions impose constraints—from which entangled particles break free.Brody explores such concepts as local realism, Bell's inequality, polarization, time dilation, and special relativity. He introduces readers to imaginary physicists Alice and Bob and their photon analyses; points out that it's easier to reject falsehood than establish the truth; and reports that some physicists explain entanglement by arguing that we live in a cross-section of a higher-dimensional reality. He examines a variety of viewpoints held by physicists, including quantum decoherence, Niels Bohr's Copenhagen interpretation, genuine fortuitousness, and QBism. This relatively recent interpretation, an abbreviation of "quantum Bayesianism,” holds that there's no such thing as an absolutely accurate, objective probability "out there,” that quantum mechanical probabilities are subjective judgments, and there's no "action at a distance,” spooky or otherwise.

A short history of cynicism, from the fearless speech of the ancient Greeks to the jaded negativity of the present.Everyone''s a cynic, yet few will admit it. Today''s cynics excuse themselves half-heartedly—“I hate to be a cynic, but..."—before making their pronouncements. Narrowly opportunistic, always on the take, contemporary cynicism has nothing positive to contribute. The Cynicism of the ancient Greeks, however, was very different. This Cynicism was a marginal philosophy practiced by a small band of eccentrics. Bold and shameless, it was committed to transforming the values on which civilization depends. In this volume of the MIT Press Essential Knowledge series, Ansgar Allen charts the long history of cynicism, from the “fearless speech” of Greek Cynics in the fourth century BCE to the contemporary cynic''s lack of social and political convictions.Allen describes ancient Cynicism as an improvised philosophy and a way of life disposed to scandalize contemporaries, subjecting their cultural commitments to derision. He chronicles the subsequent “purification” of Cynicism by the Stoics; Renaissance and Enlightenment appropriations of Cynicism, drawing on the writings of Shakespeare, Rabelais, Rousseau, de Sade, and others; and the transition from Cynicism (the philosophy) to cynicism (the modern attitude), exploring contemporary cynicism from the perspectives of its leftist, liberal, and conservative critics. Finally, he considers the possibility of a radical cynicism that admits and affirms the danger it poses to contemporary society.

An accessible introduction to the history, fundamental concepts, challenges, and controversies of the fMRI by one of the pioneers in the field.The discovery of functional MRI (fMRI) methodology in 1991 was a breakthrough in neuroscience research. This non-invasive, relatively high-speed, and high sensitivity method of mapping human brain activity enabled observation of subtle localized changes in blood flow associated with brain activity. Thousands of scientists around the world have not only embraced fMRI as a new and powerful method that complemented their ongoing studies but have also gone on to redirect their research around this revolutionary technique. This volume in the MIT Press Essential Knowledge series offers an accessible introduction to the history, fundamental concepts, challenges, and controversies of fMRI, written by one of the pioneers in the field.Peter Bandettini covers the essentials of fMRI, providing insight and perspective from his nearly three decades of research. He describes other brain imaging and assessment methods; the sources of fMRI contrasts; the basic methodology, from hardware to pulse sequences; brain activation experiment design strategies; and data and image processing. A unique, standalone chapter addresses major controversies in the field, outlining twenty-six challenges that have helped shape fMRI research. Finally, Bandettini lays out the four essential pillars of fMRI: technology, methodology, interpretation, and applications. The book can serve as a guide for the curious nonexpert and a reference for both veteran and novice fMRI scientists.

How the concept of critical thinking emerged, how it has been defined, and how critical thinking skills can be taught.Critical thinking is regularly cited as an essential twenty-first century skill, the key to success in school and work. Given our propensity to believe fake news, draw incorrect conclusions, and make decisions based on emotion rather than reason, it might even be said that critical thinking is vital to the survival of a democratic society. But what, exactly, is critical thinking? In this volume in the MIT Press Essential Knowledge series, Jonathan Haber explains how the concept of critical thinking emerged, how it has been defined, and how critical thinking skills can be taught and assessed.Haber describes the term's origins in such disciplines as philosophy, psychology, and science. He examines the components of critical thinking, including structured thinking, language skills, background knowledge, and information literacy, along with such necessary intellectual traits as intellectual humility, empathy, and open-mindedness. He discusses how research has defined critical thinking, how elements of critical thinking have been taught for centuries, and how educators can teach critical thinking skills now.Haber argues that the most important critical thinking issue today is that not enough people are doing enough of it. Fortunately, critical thinking can be taught, practiced, and evaluated. This book offers a guide for teachers, students, and aspiring critical thinkers everywhere, including advice for educational leaders and policy makers on how to make the teaching and learning of critical thinking an educational priority and practical reality.

A biography of two troublesome words.

How networked technology enables the emergence of a new collaborative society.Humans are hard-wired for collaboration, and new technologies of communication act as a super-amplifier of our natural collaborative mindset. This volume in the MIT Press Essential Knowledge series examines the emergence of a new kind of social collaboration enabled by networked technologies. This new collaborative society might be characterized as a series of services and startups that enable peer-to-peer exchanges and interactions though technology. Some believe that the economic aspects of the new collaboration have the potential to make society more equitable; others see collaborative communities based on sharing as a cover for social injustice and user exploitation.The book covers the "sharing economy,” and the hijacking of the term by corporations; different models of peer production, and motivations to participate; collaborative media production and consumption, the definitions of "amateur” and "professional,” and the power of memes; hactivism and social movements, including Anonymous and anti-ACTA protest; collaborative knowledge creation, including citizen science; collaborative self-tracking; and internet-mediated social relations, as seen in the use of Instagram, Snapchat, and Tinder. Finally, the book considers the future of these collaborative tendencies and the disruptions caused by fake news, bots, and other challenges.

An accessible introduction to the artificial intelligence technology that enables computer vision, speech recognition, machine translation, and driverless cars.Deep learning is an artificial intelligence technology that enables computer vision, speech recognition in mobile phones, machine translation, AI games, driverless cars, and other applications. When we use consumer products from Google, Microsoft, Facebook, Apple, or Baidu, we are often interacting with a deep learning system. In this volume in the MIT Press Essential Knowledge series, computer scientist John Kelleher offers an accessible and concise but comprehensive introduction to the fundamental technology at the heart of the artificial intelligence revolution.Kelleher explains that deep learning enables data-driven decisions by identifying and extracting patterns from large datasets; its ability to learn from complex data makes deep learning ideally suited to take advantage of the rapid growth in big data and computational power. Kelleher also explains some of the basic concepts in deep learning, presents a history of advances in the field, and discusses the current state of the art. He describes the most important deep learning architectures, including autoencoders, recurrent neural networks, and long short-term networks, as well as such recent developments as Generative Adversarial Networks and capsule networks. He also provides a comprehensive (and comprehensible) introduction to the two fundamental algorithms in deep learning: gradient descent and backpropagation. Finally, Kelleher considers the future of deep learning—major trends, possible developments, and significant challenges.

A comprehensive overview of developments in augmented reality, virtual reality, and mixed reality—and how they could affect every part of our lives.After years of hype, extended reality—augmented reality (AR), virtual reality (VR), and mixed reality (MR)—has entered the mainstream. Commercially available, relatively inexpensive VR headsets transport wearers to other realities—fantasy worlds, faraway countries, sporting events—in ways that even the most ultra-high-definition screen cannot. AR glasses receive data in visual and auditory forms that are more useful than any laptop or smartphone can deliver. Immersive MR environments blend physical and virtual reality to create a new reality. In this volume in the MIT Press Essential Knowledge series, technology writer Samuel Greengard offers an accessible overview of developments in extended reality, explaining the technology, considering the social and psychological ramifications, and discussing possible future directions.Greengard describes the history and technological development of augmented and virtual realities, including the latest research in the field, and surveys the various shapes and forms of VR, AR, and MR, including head-mounted displays, mobile systems, and goggles. He examines the way these technologies are shaping and reshaping some professions and industries, and explores how extended reality affects psychology, morality, law, and social constructs. It's not a question of whether extended reality will become a standard part of our world, he argues, but how, when, and where these technologies will take hold. Will extended reality help create a better world? Will it benefit society as a whole? Or will it merely provide financial windfalls for a select few? Greengard's account equips us to ask the right questions about a transformative technology.

A concise and accessible guide to techniques for detecting doctored and fake images in photographs and digital media.Stalin, Mao, Hitler, Mussolini, and other dictators routinely doctored photographs so that the images aligned with their messages. They erased people who were there, added people who were not, and manipulated backgrounds. They knew if they changed the visual record, they could change history. Once, altering images required hours in the darkroom; today, it can be done with a keyboard and mouse. Because photographs are so easily faked, fake photos are everywhere—supermarket tabloids, fashion magazines, political ads, and social media. How can we tell if an image is real or false? In this volume in the MIT Press Essential Knowledge series, Hany Farid offers a concise and accessible guide to techniques for detecting doctored and fake images in photographs and digital media.Farid, an expert in photo forensics, has spent two decades developing techniques for authenticating digital images. These techniques model the entire image-creation process in order to find the digital disruption introduced by manipulation of the image. Each section of the book describes a different technique for analyzing an image, beginning with those requiring minimal technical expertise and advancing to those at intermediate and higher levels. There are techniques for, among other things, reverse image searches, metadata analysis, finding image imperfections introduced by JPEG compression, image cloning, tracing pixel patterns, and detecting images that are computer generated. In each section, Farid describes the techniques, explains when they should be applied, and offers examples of image analysis.

An examination of the meaning of meaninglessness: why it matters that nothing matters.When someone is labeled a nihilist, it's not usually meant as a compliment. Most of us associate nihilism with destructiveness and violence. Nihilism means, literally, "an ideology of nothing. " Is nihilism, then, believing in nothing? Or is it the belief that life is nothing? Or the belief that the beliefs we have amount to nothing? If we can learn to recognize the many varieties of nihilism, Nolen Gertz writes, then we can learn to distinguish what is meaningful from what is meaningless. In this addition to the MIT Press Essential Knowledge series, Gertz traces the history of nihilism in Western philosophy from Socrates through Hannah Arendt and Jean-Paul Sartre.Although the term "nihilism” was first used by Friedrich Jacobi to criticize the philosophy of Immanuel Kant, Gertz shows that the concept can illuminate the thinking of Socrates, Descartes, and others. It is Nietzsche, however, who is most associated with nihilism, and Gertz focuses on Nietzsche's thought. Gertz goes on to consider what is not nihilism—pessimism, cynicism, and apathy—and why; he explores theories of nihilism, including those associated with Existentialism and Postmodernism; he considers nihilism as a way of understanding aspects of everyday life, calling on Adorno, Arendt, Marx, and prestige television, among other sources; and he reflects on the future of nihilism. We need to understand nihilism not only from an individual perspective, Gertz tells us, but also from a political one.

A consumer's guide to the food system, from local to global: our part as citizens in the interconnected networks, institutions, and organizations that enable our food choices.Everybody eats. We may even consider ourselves experts on the topic, or at least Instagram experts. But are we aware that the shrimp in our freezer may be farmed and frozen in Vietnam, the grapes in our fruit bowl shipped from Chile, and the coffee in our coffee maker grown in Nicaragua, roasted in Germany, and distributed in Canada? Whether we know it or not, every time we shop for food, cook, and eat, we connect ourselves to complex supply networks, institutions, and organizations that enable our food choices. Even locavores may not know the whole story of the produce they buy at the farmers market. In this volume in the MIT Press Essential Knowledge series, food writer and scholar Fabio Parasecoli offers a consumer's guide to the food system, from local to global.Parasecoli describes a system made up of open-ended, shifting, and unstable networks rather than well-defined chains; considers healthy food and the contradictory advice about it consumers receive; discusses food waste and the implications for sustainability; explores food technologies (and "culinary luddism”); and examines hunger and food insecurity in both developing and developed countries. Parasecoli reminds us that we are not only consumers but also citizens, and as citizens we have more power to improve the food system than we do by our individual food choices.

An accessible introduction to 3D printing that outlines the additive manufacturing process, industrial and household markets, and emerging uses.

An introduction to issues of sexual consent, covering key strands of feminist thought, how sexual consent is negotiated in practice, the influence of popular culture, and more.The #MeToo movement has focused public attention on the issue of sexual consent. People of all genders, from all walks of life, have stepped forward to tell their stories of sexual harassment and violation. In a predictable backlash, others have taken to mass media to inquire plaintively if "flirting” is now forbidden. This volume in the MIT Press Essential Knowledge series offers a nuanced introduction to sexual consent by a writer who is both a scholar and an activist on this issue. It has become clear from discussions of the recent high-profile cases of Harvey Weinstein, Bill Cosby, and others that there is no clear agreement over what constitutes consent or non-consent and how they are expressed and perceived in sexual situations. This book presents key strands of feminist thought on the subject of sexual consent from across academic and activist communities and covers the history of research on consent in such fields as psychology and feminist legal studies. It discusses how sexual consent is negotiated in practice, from "No means no” to "Yes means yes,” and describes what factors might limit individual agency in such negotiations. It examines how popular culture, including pornography, romance fiction, and sex advice manuals, shapes our ideas of consent; explores the communities at the forefront of consent activism; and considers what meaningful social change in this area might look like. Going beyond the conventional cisgender, heterosexual norm, the book lists additional resources for those seeking to improve their practice of consent, survivors of sexual violence, and readers who want to understand contemporary debates on this issue in more depth.

An overview of recycling as an activity and a process, following different materials through the waste stream.Is there a point to recycling? Is recycling even good for the environment? In this volume in the MIT Press Essential Knowledge series, Finn Arne Jørgensen answers (drumroll, please): it depends. From a technical point of view, recycling is a series of processes—collecting, sorting, processing, manufacturing. Recycling also has a cultural component; at its core, recycling is about transformation and value, turning material waste into something useful—plastic bags into patio furniture, plastic bottles into T-shirts. Jørgensen offers an accessible and engaging overview of recycling as an activity and as a process at the intersection of the material and the ideological. Jørgensen follows a series of materials as they move back and forth between producer and consumer, continually transforming in form and value, in a never-ceasing journey toward becoming waste. He considers organic waste and cultural contamination; the history of recyclable writing surfaces from papyrus to newsprint; discarded clothing as it moves from the the Global North to the Global South; the shifting fate of glass bottles; the efficiency of aluminum recycling; the many types of plastic and the difficulties of informed consumer choice; e-waste and technological obsolescence; and industrial waste. Finally, re-asking the question posed by John Tierney in an infamous 1996 New York Times article, "is recycling garbage?” Jørgensen argues that recycling is necessary—as both symbolic action and physical activity that has a tangible effect on the real world.
