Essays, conversations, and artist portfolios confront questions at the intersection of race, institutional life, and representation.

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.

An analysis of convergent evolution from molecules to ecosystems, demonstrating the limited number of evolutionary pathways available to life.

Selections from Gabriel Orozco''s notebooks: sketches, photographs, and texts that offer a rare look inside his art-making process.Written Matter presents selections from the notebooks of the prolific and celebrated artist Gabriel Orozco. These texts, sketches, and images from notebooks spanning 1992 to 2012 offer insights into Orozco''s artmaking process, revealing his thinking, methods, and rationales. The texts, translated from the original handwritten Spanish, offer personal truisms, compelling insights, observations, and notes on process and method, forming a subterranean stream that runs parallel to his artwork. “Art is the opposite of spectacle,” he writes. “Art does not try to convince anyone, that''s why it''s shocking.” The notebooks are fundamental to Orozco''s work, serving as a travelogue and personal dictionary that, when consulted, allow him to resume the trajectory of his thought anywhere. Because Orozco chooses not to work in a studio, his notebooks act as a different kind of studio space, on paper and bound between covers. Orozco works in a variety of media—drawing, installation, photography, sculpture, video. His notebooks reveal and revel in the style and substance of his art.Profusely illustrated and designed under Orozco''s art direction, Written Matter offers an unusually intimate look at an artist''s process and practice.

How to become a parallel programmer by learning the twenty-one essential components of OpenMP.This book guides readers through the most essential elements of OpenMP—the twenty-one components that most OpenMP programmers use most of the time, known collectively as the "OpenMP Common Core.” Once they have mastered these components, readers with no prior experience writing parallel code will be effective parallel programmers, ready to take on more complex aspects of OpenMP. The authors, drawing on twenty years of experience in teaching OpenMP, introduce material in discrete chunks ordered to support effective learning. OpenMP was created in 1997 to make it as simple as possible for applications programmers to write parallel code; since then, it has grown into a huge and complex system. The OpenMP Common Core goes back to basics, capturing the inherent simplicity of OpenMP. After introducing the fundamental concepts of parallel computing and history of OpenMP's development, the book covers topics including the core design pattern of parallel computing, the parallel and worksharing-loop constructs, the OpenMP data environment, and tasks. Two chapters on the OpenMP memory model are uniquely valuable for their pedagogic approach. The key for readers is to work through the material, use an OpenMP-enabled compiler, and write programs to experiment with each OpenMP directive or API routine as it is introduced. The book's website, updated continuously, offers a wide assortment of programs and exercises.

How the environmental provisions in US preferential trade agreements affect both the environmental policies of trading partners and the effectiveness of multilateral environmental agreements.As trade negotiations within the World Trade Organization seem permanently stalled, countries turn increasingly to preferential trade agreements (PTAs) between smaller groups of nations. Many of these PTAs incorporate environmental provisions, some of which require trading partners to enact new domestic environmental laws, and use the enforcement mechanisms available within trade agreements as tools for environmental protection. In Greening through Trade, Sikina Jinnah and Jean-Frédéric Morin provide the first detailed examination of how the environmental provisions in US preferential trade agreements affect both the environmental policies of trading partners and the effectiveness of multilateral environmental agreements. They do so through a combination of in-depth qualitative case studies and quantitative analysis of an original dataset of 688 global PTAs. Jinnah and Morin explore the effects of linkages between PTAs and environmental treaties and the diffusion of environmental norms and policy through PTAs. Centrally, they argue that US trade agreements can serve as mechanisms both to export environmental policies to trading partner nations and third-party countries and to enhance the effectiveness of multilateral environmental agreements by strengthening their enforcement capacity. They caution that PTAs are not a panacea for environmental governance; deeper problems of unsustainable consumption and differential power dynamics between trading partners must be carefully navigated in deploying trade agreements for environmental protection.

The kaleidoscope, the stereoscope, and other nineteenth-century optical toys analyzed as "new media” of their era, provoking anxieties similar to our own about children and screens.In the nineteenth century, the kaleidoscope, the thaumatrope, the zoetrope, the stereoscope, and other optical toys were standard accessories of a middle-class childhood, used both at home and at school. In Playful Visions, Meredith Bak argues that the optical toys of the nineteenth century were the "new media” of their era, teaching children to be discerning consumers of media—and also provoking anxieties similar to contemporary worries about children's screen time. Bak shows that optical toys—which produced visual effects ranging from a moving image to the illusion of depth—established and reinforced a new understanding of vision as an interpretive process. At the same time, the expansion of the middle class as well as education and labor reforms contributed to a new notion of childhood as a time of innocence and play. Modern media culture and the emergence of modern Western childhood are thus deeply interconnected.Drawing on extensive archival research, Bak discusses, among other things, the circulation of optical toys, and the wide visibility gained by their appearance as printed templates and textual descriptions in periodicals; expanding conceptions of literacy, which came to include visual acuity; and how optical play allowed children to exercise a sense of visual mastery. She examines optical toys alongside related visual technologies including chromolithography—which inspired both chromatic delight and chromophobia. Finally, considering the contemporary use of optical toys in advertising, education, and art, Bak analyzes the endurance of nineteenth-century visual paradigms.

The travels of Ijon Tichy, a Gulliver of the space age, who encounters faulty time machines, intelligent washing machines, suicidal potatoes, and other puzzling phenomena.Memoirs of a Space Traveler follows the adventures of Ijon Tichy, a Gulliver of the space age, who leads readers through strange experiments involving, among other puzzling phenomena, faulty time machines, intelligent washing machines, and suicidal potatoes. The scientists Tichy encounters make plans that are grandiose, and strike bargains that are Faustian. They pursue humanity's greatest and most ancient obsessions: immortality, artificial intelligence, and top-of-the-line consumer items.By turns satirical, philosophical, and absurd, these stories express the most starkly original and prescient notions of a master of speculative fiction.

An astronaut returns to Earth after a ten-year mission and finds a society that he barely recognizes.Stanislaw Lem's Return from the Stars recounts the experiences of Hal Bregg, an astronaut who returns from an exploratory mission that lasted ten years—although because of time dilation, 127 years have passed on Earth. Bregg finds a society that he hardly recognizes, in which danger has been eradicated. Children are "betrizated” to remove all aggression and violence—a process that also removes all impulse to take risks and explore. The people of Earth view Bregg and his crew as "resuscitated Neanderthals,” and pressure them to undergo betrization. Bregg has serious difficulty in navigating the new social mores.While Lem's depiction of a risk-free society is bleak, he does not portray Bregg and his fellow astronauts as heroes. Indeed, faced with no opposition to his aggression, Bregg behaves abominably. He is faced with a choice: leave Earth again and hope to return to a different society in several hundred years, or stay on Earth and learn to be content. With Return from the Stars, Lem shows the shifting boundaries between utopia and dystopia.

The second edition of a comprehensive account of all the major aspects of the Japanese economy, substantially updated and expanded.This textbook offers a comprehensive, rigorous but accessible account of all the major aspects of the Japanese economy, grounding its approach in mainstream economics. The second edition has been extensively revised and substantially updated, with new material that covers Japan's period of economic stagnation between 1991 and 2010. The first edition, published in 1992, focused on Japan as a success story of catch-up economic development; this edition reflects the lessons learned from Japan's Lost Two Decades.After presenting the historical background, the book begins with macroeconomics, studying growth and business cycles. It then covers essential policy issues, with new material that takes into account the Japanese banking crisis of 1997-1998 and the global financial crisis of 2008-2009, discussing financial regulation, monetary policy, and fiscal policy. It goes on to examine saving, demography, and social security in light of Japan's ongoing demographic transition; industrial organization; labor markets; international trade and international finance; and the Japan-U.S. relationship. A new chapter offers a detailed analysis of the Lost Two Decades, synthesizing and applying concepts discussed in previous chapters and offering insights into such issues as successful catch-up growth, demographic shifts, and credit booms and busts.

How the US Environmental Protection Agency designed the governance of risk and forged its legitimacy over the course of four decades.The US Environmental Protection Agency was established in 1970 to protect the public health and environment, administering and enforcing a range of statutes and programs. Over four decades, the EPA has been a risk bureaucracy, formalizing many of the methods of the scientific governance of risk, from quantitative risk assessment to risk ranking. Demortain traces the creation of these methods for the governance of risk, the controversies to which they responded, and the controversies that they aroused in turn. He discusses the professional networks in which they were conceived; how they were used; and how they served to legitimize the EPA. Demortain argues that the EPA is structurally embedded in controversy, resulting in constant reevaluation of its credibility and fueling the evolution of the knowledge and technologies it uses to produce decisions and to create a legitimate image of how and why it acts on the environment. He describes the emergence and institutionalization of the risk assessment-risk management framework codified in the National Research Council's Red Book, and its subsequent unraveling as the agency's mission evolved toward environmental justice, ecological restoration, and sustainability, and as controversies over determining risk gained vigor in the 1990s. Through its rise and fall at the EPA, risk decision-making enshrines the science of a bureaucracy that learns how to make credible decisions and to reform itself, amid constant conflicts about the environment, risk, and its own legitimacy.

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 examination of the implications for society of rapidly advancing artificial intelligence systems, combining a humanities perspective with technical analysis; includes exercises and discussion questions.AI and Humanity provides an analytical framing and a common language for understanding the effects of technological advances in artificial intelligence on society. Coauthored by a computer scientist and a scholar of literature and cultural studies, it is unique in combining a humanities perspective with technical analysis, using the tools of literary explication to examine the societal impact of AI systems. It explores the historical development of these technologies, moving from the apparently benign Roomba to the considerably more sinister semi-autonomous weapon system Harpy. The book is driven by an exploration of the cultural and etymological roots of a series of keywords relevant to both AI and society. Works examined range from Narrative of the Life of Frederick Douglass, given a close reading for its themes of literacy and agency, to Simon Head's critique of the effects of surveillance and automation on the Amazon labor force in Mindless.Originally developed as a textbook for an interdisciplinary humanities-science course at Carnegie Mellon, AI & Humanity offers discussion questions, exercises (including journal writing and concept mapping), and reading lists. A companion website provides updated resources and a portal to a video archive of interviews with AI scientists, sociologists, literary theorists, and others.

A substantially revised third edition of a comprehensive textbook that covers a broad range of topics not often included in introductory texts.

How global contemporary art reanimates the past as a resource for the present, combating modern art's legacy of Eurocentrism.If European modernism was premised on the new—on surpassing the past, often by assigning it to the "traditional” societies of the Global South—global contemporary art reanimates the past as a resource for the present. In this account of what globalization means for contemporary art, David Joselit argues that the creative use of tradition by artists from around the world serves as a means of combatting modern art's legacy of Eurocentrism. Modernism claimed to live in the future and relegated the rest of the world to the past. Global contemporary art shatters this myth by reactivating various forms of heritage—from literati ink painting in China to Aboriginal painting in Australia—in order to propose new and different futures. Joselit analyzes not only how heritage becomes contemporary through the practice of individual artists but also how a cultural infrastructure of museums, biennials, and art fairs worldwide has emerged as a means of generating economic value, attracting capital and tourist dollars.Joselit traces three distinct forms of modernism that developed outside the West, in opposition to Euro-American modernism: postcolonial, socialist realism, and the underground. He argues that these modern genealogies are synchronized with one another and with Western modernism to produce global contemporary art. Joselit discusses curation and what he terms "the curatorial episteme,” which, through its acts of framing or curating, can become a means of recalibrating hierarchies of knowledge—and can contribute to the dual projects of decolonization and deimperialization.

An argument that we must read code for more than what it does—we must consider what it means.Computer source code has become part of popular discourse. Code is read not only by programmers but by lawyers, artists, pundits, reporters, political activists, and literary scholars; it is used in political debate, works of art, popular entertainment, and historical accounts. In this book, Mark Marino argues that code means more than merely what it does; we must also consider what it means. We need to learn to read code critically. Marino presents a series of case studies—ranging from the Climategate scandal to a hactivist art project on the US-Mexico border—as lessons in critical code reading.Marino shows how, in the process of its circulation, the meaning of code changes beyond its functional role to include connotations and implications, opening it up to interpretation and inference—and misinterpretation and reappropriation. The Climategate controversy, for example, stemmed from a misreading of a bit of placeholder code as a "smoking gun” that supposedly proved fabrication of climate data. A poetry generator created by Nick Montfort was remixed and reimagined by other poets, and subject to literary interpretation.Each case study begins by presenting a small and self-contained passage of code—by coders as disparate as programming pioneer Grace Hopper and philosopher Friedrich Kittler—and an accessible explanation of its context and functioning. Marino then explores its extra-functional significance, demonstrating a variety of interpretive approaches.

A unified, comprehensive, and up-to-date introduction to the analytical and numerical tools for solving dynamic economic problems.

An introduction to financial tools and concepts from an operations perspective, addressing finance/operations trade-offs and explaining financial accounting, working capital, investment analysis, and more.Students and practitioners in engineering and related areas often lack the basic understanding of financial tools and concepts necessary for a career in operations or supply chain management. This book offers an introduction to finance fundamentals from an operations perspective, enabling operations and supply chain professionals to develop the skills necessary for interacting with finance people at a practical level and for making sound decisions when confronted by tradeoffs between operations and finance. Readers will learn about the essentials of financial statements, valuation tools, and managerial accounting.The book first discusses financial accounting, explaining how to create and interpret balance sheets, income statements, and cash flow statements, and introduces the idea of operating working capital—a key concept developed in subsequent chapters. The book then covers financial forecasting, addressing such topics as sustainable growth and the liquidity/profitability tradeoff; concepts in managerial accounting, including variable versus fixed costs, direct versus indirect costs, and contribution margin; tools for investment analysis, including net present value and internal rate of return; creation of value through operating working capital, inventory management, payables, receivables, and cash; and such strategic and tactical tradeoffs as offshoring versus local and centralizing versus decentralizing. The book can be used in undergraduate and graduate courses and as a reference for professionals. No previous knowledge of finance or accounting is required.

The evidential role of matter—when media records trace evidence of violence—explored through a series of cases drawn from Kosovo, Japan, Vietnam, and elsewhere.In this book, Susan Schuppli introduces a new operative concept: material witness, an exploration of the evidential role of matter as both registering external events and exposing the practices and procedures that enable matter to bear witness. Organized in the format of a trial, Material Witness moves through a series of cases that provide insight into the ways in which materials become contested agents of dispute around which stake holders gather.These cases include an extraordinary videotape documenting the massacre at Izbica, Kosovo, used as war crimes evidence against Slobodan Milošević; the telephonic transmission of an iconic photograph of a South Vietnamese girl fleeing an accidental napalm attack; radioactive contamination discovered in Canada''s coastal waters five years after the accident at Fukushima Daiichi; and the ecological media or “disaster film” produced by the Deep Water Horizon oil spill in the Gulf of Mexico. Each highlights the degree to which a rearrangement of matter exposes the contingency of witnessing, raising questions about what can be known in relationship to that which is seen or sensed, about who or what is able to bestow meaning onto things, and about whose stories will be heeded or dismissed.An artist-researcher, Schuppli offers an analysis that merges her creative sensibility with a forensic imagination rich in technical detail. Her goal is to relink the material world and its affordances with the aesthetic, the juridical, and the political.

How the approaches and methods of think tanks—including systems theory, operational research, and cybernetics—paved the way for a peculiar genre of midcentury modernism.In Think Tank Aesthetics, Pamela Lee traces the complex encounters between Cold War think tanks and the art of that era. Lee shows how the approaches and methods of think tanks—including systems theory, operations research, and cybernetics—paved the way for a peculiar genre of midcentury modernism and set the terms for contemporary neoliberalism. Lee casts these shadowy institutions as sites of radical creativity and interdisciplinary practice in the service of defense strategy. Describing the distinctive aesthetics that emerged from such institutions as the RAND Corporation, she maps the multiple and overlapping networks that connected nuclear strategists, mathematicians, economists, anthropologists, artists, designers, and art historians.Lee recounts, among other things, the decades-long colloquy between Albert Wohlstetter, a RAND analyst, and his former professor, the famous art historian Meyer Schapiro; the anthropologist Margaret Mead''s deployment of innovative visual aids that recall midcentury abstract art; and the combination of cybernetics and modernist design in an “Opsroom” for the short-lived socialist government of Salvador Allende in 1970s Chile (and its restaging many years later as a work of art). Lee suggests that we think of these connections less as disciplinary border crossings than as colonization of the specific interests of arts by the approaches and methods of the sciences. Hearing the echoes of think tank aesthetics in today''s pursuit of the interdisciplinary and in academia''s science-infused justification of the humanities, Lee wonders what territory has been ceded in a laboratory approach to the arts.

An argument that Modernism is a cognitive phenomenon rather than a cultural one.At the beginning of the twentieth century, poetry, music, and painting all underwent a sea change. Poetry abandoned rhyme and meter; music ceased to be tonally centered; and painting no longer aimed at faithful representation. These artistic developments have been attributed to cultural factors ranging from the Industrial Revolution and the technical innovation of photography to Freudian psychoanalysis. In this book, Samuel Jay Keyser argues that the stylistic innovations of Western modernism reflect not a cultural shift but a cognitive one. Behind modernism is the same cognitive phenomenon that led to the scientific revolution of the seventeenth century: the brain coming up against its natural limitations. Keyser argues that the transformation in poetry, music, and painting (the so-called sister arts) is the result of the abandonment of a natural aesthetic based on a set of rules shared between artist and audience, and that this is virtually the same cognitive shift that occurred when scientists abandoned the mechanical philosophy of the Galilean revolution. The cultural explanations for Modernism may still be relevant, but they are epiphenomenal rather than causal. Artists felt that traditional forms of art had been exhausted, and they began to resort to private formats—Easter eggs with hidden and often inaccessible meaning. Keyser proposes that when artists discarded their natural rule-governed aesthetic, it marked a cognitive shift; general intelligence took over from hardwired proclivity. Artists used a different part of the brain to create, and audiences were forced to play catch up.

How to survive the digital revolution without getting trampled: your guide to online mindfulness, digital self-empowerment, cybersecurity, creepy ads, trustworthy information, and more.Feeling overwhelmed by an avalanche of online content? Anxious about identity theft? Unsettled by the proliferation of fake news? Welcome to the digital revolution. Wait—wasn't the digital revolution supposed to make our lives better? It was going to be fun and put the world at our fingertips. What happened? Keep Calm and Log On is a survival handbook that will help you achieve online mindfulness and overcome online helplessness—the feeling that tech is out of your control—with tips for handling cybersecurity, creepy ads, untrustworthy information, and much more.Taking a cue from the famous World War II morale-boosting slogan ("Keep Calm and Carry On”), Gus Andrews shows us how to adapt the techniques our ancestors used to survive hard times, so we can live our best lives online. She explains why media and technology stress us out, and offers empowering tools for coping. Mindfulness practices can help us stay calm and conserve our attention purposefully. Andrews shares the secret of understanding our own opinions'' "family trees” in order to identify misleading "fake news.” She provides tools for unplugging occasionally, overcoming feelings that we are "bad at technology,” and taking charge of our security and privacy. Andrews explains how social media algorithms keep us from information we need and why "creepy ads” seem to follow us online. Most importantly, she urges us to work to rebuild the trust in our communities that the internet has broken.

Architects imagine the planet: fifty speculative world-scale projects from Patrick Geddes, Alison and Peter Smithson, Kiyonori Kikutake, Juan Navarro Baldeweg, Luc Deleu, and others. The world's growing vulnerability to planet-sized risks invites action on a global scale. The World as an Architectural Project shows how for more than a century architects have imagined the future of the planet through world-scale projects. With fifty speculative projects by Patrick Geddes, Alison and Peter Smithson, Kiyonori Kikutake, Saverio Muratori, Takis Zenetos, Sergio Bernardes, Juan Navarro Baldeweg, Luc Deleu, and many others, documented in text and images, this ambitious and wide-ranging book is the first compilation of its kind.Interestingly, architects begin to address the world as a project long before the advent of contemporary globalism and its assorted anxieties. The Spanish urban theorist and entrepreneur Arturo Soria y Mata, for example, in 1882 envisions a system that connects the entire planet in a linear urban network. In 1927, Buckminster Fuller's "World Town Plan—4D Tower” proposes to solve global housing problems with mobile structures delivered and installed by a Zeppelin. And Joyce Hsiang and Bimal Mendis visualize the conditions of a worldwide "City of Seven Billion” in a 2015-2019 project. Rather than indulging the cliché of the megalomaniac architect, this volume presents a discipline reflecting on its own responsibilities.

A self-contained introduction to abstract interpretation-based static analysis, an essential resource for students, developers, and users.Static program analysis, or static analysis, aims to discover semantic properties of programs without running them. It plays an important role in all phases of development, including verification of specifications and programs, the synthesis of optimized code, and the refactoring and maintenance of software applications. This book offers a self-contained introduction to static analysis, covering the basics of both theoretical foundations and practical considerations in the use of static analysis tools. By offering a quick and comprehensive introduction for nonspecialists, the book fills a notable gap in the literature, which until now has consisted largely of scientific articles on advanced topics.The text covers the mathematical foundations of static analysis, including semantics, semantic abstraction, and computation of program invariants; more advanced notions and techniques, including techniques for enhancing the cost-accuracy balance of analysis and abstractions for advanced programming features and answering a wide range of semantic questions; and techniques for implementing and using static analysis tools. It begins with background information and an intuitive and informal introduction to the main static analysis principles and techniques. It then formalizes the scientific foundations of program analysis techniques, considers practical aspects of implementation, and presents more advanced applications. The book can be used as a textbook in advanced undergraduate and graduate courses in static analysis and program verification, and as a reference for users, developers, and experts.

A comprehensive introduction to the latest research and theory on learning and instruction with computer games.This book offers a comprehensive introduction to the latest research on learning and instruction with computer games. Unlike other books on the topic, which emphasize game development or best practices, Handbook of Game-Based Learning is based on empirical findings and grounded in psychological and learning sciences theory. The contributors, all leading researchers in the field, offer a range of perspectives, including cognitive, motivational, affective, and sociocultural. They explore research on whether (and how) computer games can help students learn educational content and academic skills; which game features (including feedback, incentives, adaptivity, narrative theme, and game mechanics) can improve the instructional effectiveness of these games; and applications, including games for learning in STEM disciplines, for training cognitive skills, for workforce learning, and for assessment. The Handbook offers an indispensable reference both for readers with practical interests in designing or selecting effective game-based learning environments and for scholars who conduct or evaluate research in the field. It can also be used in courses related to play, cognition, motivation, affect, instruction, and technology.ContributorsRoger Azevedo, Ryan S. Baker, Daphne Bavelier, Amanda E. Bradbury, Ruth C.

This “well-researched, nuanced” study of the rise of social media activism explores how marginalized groups use Twitter to advance counter-narratives, preempt political spin, and build diverse networks of dissent (Ms.)   The power of hashtag activism became clear in 2011, when #IranElection served as an organizing tool for Iranians protesting a disputed election and offered a global audience a front-row seat to a nascent revolution. Since then, activists have used a variety of hashtags, including #JusticeForTrayvon, #BlackLivesMatter, #YesAllWomen, and #MeToo to advocate, mobilize, and communicate. In this book, Sarah Jackson, Moya Bailey, and Brooke Foucault Welles explore how and why Twitter has become an important platform for historically disenfranchised populations, including Black Americans, women, and transgender people. They show how marginalized groups, long excluded from elite media spaces, have used Twitter hashtags to advance counternarratives, preempt political spin, and build diverse networks of dissent.   The authors describe how such hashtags as #MeToo, #SurvivorPrivilege, and #WhyIStayed have challenged the conventional understanding of gendered violence; examine the voices and narratives of Black feminism enabled by #FastTailedGirls, #YouOKSis, and #SayHerName; and explore the creation and use of #GirlsLikeUs, a network of transgender women. They investigate the digital signatures of the “new civil rights movement”—the online activism, storytelling, and strategy-building that set the stage for #BlackLivesMatter—and recount the spread of racial justice hashtags after the killing of Michael Brown in Ferguson, Missouri, and other high-profile incidents of killings by police. Finally, they consider hashtag created by allies, including #AllMenCan and #CrimingWhileWhite.

The different ways that social change happens, from unleashing to nudging to social cascades.
