FaceSpace (Orca Currents)
by Adrian ChamberlainDanny McBride is not the coolest kid in school, not in his wildest dreams. And if the other kids knew he spent his Saturday nights playing Parcheesi with his mom and working on a city made of Lego, he'd be even less cool. Danny wants more than anything to be popular. He creates a fictional British rocker named James and befriends him publicly online, hoping his make-believe friend's cool will rub off. It works. Danny starts making friends and feeling like part of the crowd—until people start wanting to meet the imaginary friend, and Danny's plan starts to unravel.
Facets of Behaviormetrics: The 50th Anniversary of the Behaviormetric Society (Behaviormetrics: Quantitative Approaches to Human Behavior #4)
by Akinori Okada Kazuo Shigemasu Ryozo Yoshino Satoru YokoyamaThis edited book is the first one written in English that deals comprehensively with behavior metrics. The term “behaviormetrics” comprehends the research including all sorts of quantitative approaches to disclose human behavior. Researchers in behavior metrics have developed, extended, and improved methods such as multivariate statistical analysis, survey methods, cluster analysis, machine learning, multidimensional scaling, corresponding analysis or quantification theory, network analysis, clustering, factor analysis, test theory, and related factors. In the spirit of behavior metrics, researchers applied these methods to data obtained by surveys, experiments, or websites from a diverse range of fields. The purpose of this book is twofold. One is to represent studies that display how the basic elements of behavior metrics have developed into present-day behavior metrics. The other is to represent studies performed mainly by those who would like to pioneer new fields of behavior metrics and studies that display elements of future behavior metrics. These studies consist of various characteristics such as those dealing with theoretical or conceptual subjects, the algorithm, the model, the method, and the application to a wide variety of fields. This book helps readers to understand the present and future of behavior metrics.
Facets of Combinatorial Optimization: Festschrift for Martin Grötschel
by Michael Jünger Gerhard ReineltMartin Grötschel is one of the most influential mathematicians of our time. He has received numerous honors and holds a number of key positions in the international mathematical community. He celebrated his 65th birthday on September 10, 2013. Martin Grötschel's doctoral descendant tree 1983-2012, i.e., the first 30 years, features 39 children, 74 grandchildren, 24 great-grandchildren, and 2 great-great-grandchildren, a total of 139 doctoral descendants. This book starts with a personal tribute to Martin Grötschel by the editors (Part I), a contribution by his very special "predecessor" Manfred Padberg on "Facets and Rank of Integer Polyhedra" (Part II), and the doctoral descendant tree 1983-2012 (Part III). The core of this book (Part IV) contains 16 contributions, each of which is coauthored by at least one doctoral descendant. The sequence of the articles starts with contributions to the theory of mathematical optimization, including polyhedral combinatorics, extended formulations, mixed-integer convex optimization, superclasses of perfect graphs, efficient algorithms for subtree-telecenters, junctions in acyclic graphs, and preemptive restricted strip covering, as well as efficient approximation of non-preemptive restricted strip covering. Combinations of new theoretical insights with algorithms and experiments deal with network design problems, combinatorial optimization problems with submodular objective functions, and more general mixed-integer nonlinear optimization problems. Applications include VLSI layout design, systems biology, wireless network design, mean-risk optimization, and gas network optimization. Computational studies include a semidefinite branch and cut approach for the max k-cut problem, mixed-integer nonlinear optimal control, and mixed-integer linear optimization for scheduling and routing of fly-in safari planes. The two closing articles are devoted to computational advances in general mixed integer linear optimization, the first by scientists working in industry, the second by scientists working in academia. These articles reflect the "scientific facets" of Martin Grötschel who has set standards in theory, computation, and applications.
Facets of Uncertainties and Applications
by Mihir K. Chakraborty Andrzej Skowron Manoranjan Maiti Samarjit KarSince the emergence of the formal concept of probability theory in the seventeenth century, uncertainty has been perceived solely in terms of probability theory. However, this apparently unique link between uncertainty and probability theory has come under investigation a few decades back. Uncertainties are nowadays accepted to be of various kinds. Uncertainty in general could refer to different sense like not certainly known, questionable, problematic, vague, not definite or determined, ambiguous, liable to change, not reliable. In Indian languages, particularly in Sanskrit-based languages, there are other higher levels of uncertainties. It has been shown that several mathematical concepts such as the theory of fuzzy sets, theory of rough sets, evidence theory, possibility theory, theory of complex systems and complex network, theory of fuzzy measures and uncertainty theory can also successfully model uncertainty.
Facilitating Breakthrough: How to Remove Obstacles, Bridge Differences, and Move Forward Together
by Adam KahaneMaking progress on complex, problematic situations requires a new approach to working together: transformative facilitation, a structured and creative process for removing the obstacles to fluid forward movement. It is becoming less straightforward for people to move forward together. They face increasing complexity and decreasing control. They need to work with more people from across more divides. In such situations, the most common ways of advancing—some people telling others what to do, or everyone just doing what they think they need to—aren't adequate.One better way is through facilitating. But the most common approaches to facilitating—bossy vertical directing from above or collegial horizontal accompanying from alongside—aren't adequate. They often leave the participants frustrated and yearning for breakthrough.This book describes a new approach: transformative facilitation. It doesn't choose either the bossy vertical or the collegial horizontal approach: it cycles back and forth between them. Rather than forcing or cajoling, the facilitator removes the obstacles that stand in the way of people contributing and connecting equitably. It enables people to bring their whole selves to the process. This book is foranyone who helps people work together to transform their situation, be it a professional facilitator, manager, consultant, coach, chairperson, organizer, mediator, stakeholder, or friend.It offers a broad and bold vision of the contribution that facilitation can make to helping people collaborate to make progress.

Facing the Beast: Courage, Faith, and Resistance in a New Dark Age
by Naomi WolfFrom New York Times bestselling author Naomi Wolf, Facing the Beast is a devastating, detailed account of wrongthink, deplatforming, and an unexpected political, personal, and spiritual transformation that followed during one of the most divisive times in American history. In this uncompromising investigation into today’s most urgent issues, Naomi Wolf uses her own wildly politicized pilgrimage—from New York Times bestselling author and high-level Democratic consultant to a journalist cast out from the elite political and social circles she once moved through—as a stunning narrative framework that is both chilling and incisive. Wolf’s sin? Doing the job that good journalists once prided themselves on: asking questions, challenging authority, and, during one of the most politically divisive moments in modern history, exposing the many failures of the public health response during the COVID-19 pandemic by chronicling the dangerous descent of our democracy into tyranny, censorship, and totalitarianism. Unable to remain silent in the shadows and unwilling to collude with the mainstream, Wolf bravely covers topics that few other writers dare to address critically for fear of being deplatformed. Facing the Beast explores reproductive rights, medical freedom, the uncurious thought-policing of the “progressive” left, the Second Amendment, the criminal relationship between the FDA and Pfizer—Wolf’s clear writing repeatedly shines light in the dark corners of our fractured society. A decades-long champion of free speech, freedom of the press, and the Constitution, Wolf found herself not only in the midst of a political rebirth but a spiritual transformation as well—one in which the events of the day could only be described in terms of good, evil, and a metaphysical quest on the nature of reality. For readers of Matt Taibbi, Glenn Greenwald, and Bari Weiss, Facing the Beast is a fearless indictment of legacy media and the political class, as well as a brutal reminder that searching for and defending the truth can be dangerous. “Naomi Wolf is one of the bravest, clearest-thinking people I know. The reason you hear the forces of repression so desperately trying to dismiss her is because she is right.”—Tucker Carlson

by Stefan Panic Mihajlo Stefanovic Jelena Anastasov Petar SpalevicFading and Interference Mitigation in Wireless Communications will help readers stay up to date with recent developments in the performance analysis of space diversity reception over fading channels in the presence of cochannel interference. It presents a unified method for computing the performance of digital communication systems characterized by a variety of modulation and detection types and channel models. The book includes coverage of multichannel reception in various fading environments, influence of cochannel interference, and macrodiversity reception when channels are simultaneously affected by various types of fading and shadowing.
Fading and Shadowing in Wireless Systems
by P. Mohana ShankarThe study of signal transmission and deterioration in signal characteristics as the signal propagates through wireless channels is of great significance. The book presents a comprehensive view of channel degradation arising from fading and shadowing. Various statistical models including simple, hybrid, compound, complex and cascaded ones are presented with detailed derivations along with measures to quantify the deterioration such as the amount of fading, error rates and outage probabilities. The models range from the Rayleigh and Rician through Suzuki, generalized K, cascaded and alpha-mu and similar ones. This is followed by the analysis of mitigation of fading and shadowing through diversity (simple, hybrid, micro- and macro- level) and combining algorithms. The density and distribution functions, error rates and outages are derived and results analyzed to quantify the improvements. The effects of co-channel interference before and after the implementation of diversity are also analyzed. To facilitate easy understanding of the models and analysis, the background information in terms of probability and random variables is presented with relevant derivations of densities of linear and nonlinear transformation of random variables, the sums, products, ratios as well as order statistics of random variables of all types. The book also provides material on digital modems of interest in wireless systems. Thus, the book with 1100+ equations and 350+ Matlab generated figures and tables is an ideal source for students, educators, researchers and professionals in wireless communications allowing access to information currently unavailable.

Failure to Connect: How Computers Affect Our Children's Minds and What We Can Do About It
by Jane M. HealyIn this comprehensive, practical, and unsettling look at computers in children's lives, Jane M. Healy, Ph.D., questions whether computers are really helping or harming children's development. Once a bedazzled enthusiast of educational computing but now a troubled skeptic, Dr. Healy examines the advantages and drawbacks of computer use for kids at home and school, exploring its effects on children's health, creativity, brain development, and social and emotional growth. Today, the Federal Government allocates scarce educational funding to wire every classroom to the Internet, software companies churn out "educational" computer programs even for preschoolers, and school administrators cut funding and space for books, the arts, and physical education to make room for new computer hardware. It is past the time to address these issues. Many parents and even some educators have been sold on the idea that computer literacy is as important as reading and math. Those who haven't hopped on the techno bandwagon are left wondering whether they are shortchanging their children's education or their students' futures. Few people stop to consider that computers, used incorrectly, may do far more harm than good. New technologies can be valuable educational tools when used in age-appropriate ways by properly trained teachers. But too often schools budget insufficiently for teacher training and technical support. Likewise, studies suggest that few parents know how to properly assist children's computer learning; much computer time at home may be wasted time, drawing children away from other developmentally important activities such as reading, hobbies, or creative play. Moreover, Dr. Healy finds that much so-called learning software is more "edutainment" than educational, teaching students more about impulsively pointing and clicking for some trivial goal than about how to think, to communicate, to imagine, or to solve problems. Some software, used without careful supervision, may also have the potential to interrupt a child's internal motivation to learn. Failure to Connect is the first book to link children's technology use to important new findings about stages of child development and brain maturation, which are clearly explained throughout. It illustrates, through dozens of concrete examples and guidelines, how computers can be used successfully with children of different age groups as supplements to classroom curricula, as research tools, or in family projects. Dr. Healy issues strong warnings, however, against too early computer use, recommending little or no exposure before age seven, when the brain is primed to take on more abstract challenges. She also lists resources for reliable reviews of child-oriented software, suggests questions parents should ask when their children are using computers in school, and discusses when and how to manage computer use at home. Finally, she offers a thoughtful look at the question of which skills today's children will really need for success in a technological future -- and how they may best acquire them. Based on years of research into learning and hundreds of hours of interviews and observations with school administrators, teachers, parents, and students, Failure to Connect is a timely and eye-opening examination of the central questions we must confront as technology increasingly influences the way we educate our children.
Failure to Disrupt: Why Technology Alone Can’t Transform Education
by Justin ReichA leader in educational technology separates truth from hype, explaining what tech can—and can’t—do to transform our classrooms.Proponents of large-scale learning have boldly promised that technology can disrupt traditional approaches to schooling, radically accelerating learning and democratizing education. Much-publicized experiments, often underwritten by Silicon Valley entrepreneurs, have been launched at elite universities and in elementary schools in the poorest neighborhoods. Such was the excitement that, in 2012, the New York Times declared the “year of the MOOC.” Less than a decade later, that pronouncement seems premature.In Failure to Disrupt: Why Technology Alone Can’t Transform Education, Justin Reich delivers a sobering report card on the latest supposedly transformative educational technologies. Reich takes readers on a tour of MOOCs, autograders, computerized “intelligent tutors,” and other educational technologies whose problems and paradoxes have bedeviled educators. Learning technologies—even those that are free to access—often provide the greatest benefit to affluent students and do little to combat growing inequality in education. And institutions and investors often favor programs that scale up quickly, but at the expense of true innovation. It turns out that technology cannot by itself disrupt education or provide shortcuts past the hard road of institutional change.Technology does have a crucial role to play in the future of education, Reich concludes. We still need new teaching tools, and classroom experimentation should be encouraged. But successful reform efforts will focus on incremental improvements, not the next killer app.
Fair Scheduling in High Performance Computing Environments
by Art Sedighi Milton SmithThis book introduces a new scheduler to fairly and efficiently distribute system resources to many users of varying usage patterns compete for them in large shared computing environments. The Rawlsian Fair scheduler developed for this effort is shown to boost performance while reducing delay in high performance computing workloads of certain types including the following four types examined in this book: i. Class A – similar but complementary workloads ii. Class B – similar but steady vs intermittent workloads iii. Class C – Large vs small workloads iv. Class D – Large vs noise-like workloads This new scheduler achieves short-term fairness for small timescale demanding rapid response to varying workloads and usage profiles. Rawlsian Fair scheduler is shown to consistently benefit workload Classes C and D while it only benefits Classes A and B workloads where they become disproportionate as the number of users increases. A simulation framework, dSim, simulates the new Rawlsian Fair scheduling mechanism. The dSim helps achieve instantaneous fairness in High Performance Computing environments, effective utilization of computing resources, and user satisfaction through the Rawlsian Fair scheduler.

Fake news: Cómo se fabrican en la Argentina y en el mundo
by Julián MaradeoA partir de casos locales y del mundo, el libro cuenta la historia de las noticias falsas, de cómo nos ponen en estado de alerta y, al mismo tiempo, refleja la debilidad estatal, la falta de control y el enorme lobby alrededor de ellas. La imagen de una chica con su bebé en brazos mientras carga en la espalda una caja térmica de delivery es la punta del iceberg de un fenómeno que sacudió las nociones de verdad y mentira: las fake news. Todos estamos expuestos y a la vez las reproducimos hasta convertirlas en pandémicas. Sus consecuencias pueden alterar elecciones, decisiones de gobierno e incluso provocar muertes. A partir de casos locales y del mundo, el libro cuenta la historia de las noticias falsas, de cómo nos ponen en estado de alerta y, al mismo tiempo, reflejan la debilidad estatal, la falta de control y el enorme lobby alrededor de ellas. «Esta investigación -dice Julián Maradeo- trata sobre otra forma de ejercer el poder. Una que es imperceptible, escurridiza, placentera y extraterritorial. Una que jaquea a todas las teorías que discurrieron por siglos al respecto. Una en la que interviene un lenguaje que resulta ajeno, sujetos que parecen salidos de una película, geografías remotas. Una que pone en entredicho las reglas del juego democrático. Las noticias falsas no discriminan entre Oriente y Occidente, afectan a todos sin mirar a quién».
Fake News: Understanding Media and Misinformation in the Digital Age (Information Policy)
by Melissa Zimdars Kembrew McLeodNew perspectives on the misinformation ecosystem that is the production and circulation of fake news.What is fake news? Is it an item on Breitbart, an article in The Onion, an outright falsehood disseminated via Russian bot, or a catchphrase used by a politician to discredit a story he doesn't like? This book examines the real fake news: the constant flow of purposefully crafted, sensational, emotionally charged, misleading or totally fabricated information that mimics the form of mainstream news. Rather than viewing fake news through a single lens, the book maps the various kinds of misinformation through several different disciplinary perspectives, taking into account the overlapping contexts of politics, technology, and journalism.The contributors consider topics including fake news as “disorganized” propaganda; folkloric falsehood in the “Pizzagate” conspiracy; native advertising as counterfeit news; the limitations of regulatory reform and technological solutionism; Reddit's enabling of fake news; the psychological mechanisms by which people make sense of information; and the evolution of fake news in America. A section on media hoaxes and satire features an oral history of and an interview with prankster-activists the Yes Men, famous for parodies that reveal hidden truths. Finally, contributors consider possible solutions to the complex problem of fake news—ways to mitigate its spread, to teach students to find factually accurate information, and to go beyond fact-checking.ContributorsMark Andrejevic, Benjamin Burroughs, Nicholas Bowman, Mark Brewin, Elizabeth Cohen, Colin Doty, Dan Faltesek, Johan Farkas, Cherian George, Tarleton Gillespie, Dawn R.

Fake News in Context
by Lesley S. FarmerFake News in Context defines fake news and sets it within a historical and international context. Helping readers to become more skilled at detecting misinformation, the book also demonstrates how such knowledge can be leveraged to facilitate more effective engagement in civic education. Distinguishing between fake news and other forms of misinformation, the book explains the complete communication cycle of fake news: how and why it is created, disseminated and accessed. The book then explains the physical and psychological reasons why people believe fake news. Providing generic methods for identifying fake news, Farmer also explains the use of fact- checking tools and automated algorithms. The book then details how various literacies, including news, media, visual, information, digital and data, offer unique concepts and skills that can help interpret fake news. Arguing that individuals and groups can respond and counter fake news, which leads to civic engagement and digital citizenship, the book concludes by providing strategies for instruction and tips for collaborating with librarians. Including a range of international examples, Fake News in Context will be of interest to teaching faculty, and students of library and information science, communication studies, media studies, politics and journalism. Librarians and information professionals will also find a valuable resource in this book.
Fake Photos (The MIT Press Essential Knowledge Series)
by Hany FaridA 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.
Fake Politics: How Corporate and Government Groups Create and Maintain a Monopoly on Truth
by Jason BisnoffIn “grassroots” campaigns, the grass isn’t always green—or natural.In today’s chaotic world, where the multiplication of information sources creates competing narratives, credibility is the key to winning the war of ideas. This is the reason why governments and corporations resort to astroturfing—creation of ostensibly grassroots movements set up to advance political agendas and commercial campaigns. The democratization of information and polarization of politics offer a perfect storm.Fake Politics tells the stories of how this practice has transformed political activism into a veiled lobbying effort by the rich and the powerful. Through a series of vignettes involving the tea party, oil industry, big tobacco, big data, and news media, this book will explore the similarities and differences between various campaigns that appeared as grassroots but, in reality, were lobbying efforts fueled by governments, corporations, major industries, and religious institutions.The process, named for the artificial grass fields at football stadiums and high schools across the country, became so prevalent in the last two decades that it now sits at a tipping point. In the era of “fake news” and “alternative facts,” with the truth well on its way to becoming indistinguishable from fabrication, what can the past of astroturfing tell us about the future of grassroots activism?
Faking It: Artificial Intelligence in a Human World
by Toby Walsh‘Refreshingly clear-eyed … Faking It is an insightful and intelligent book that’s a must for those looking for facts about AI hype.’ – Books+Publishing‘AI will be as big a game-changer as the smart phone and the personal computer – or bigger! This book will help you navigate the revolution.’ – Dr Karl KruszelnickiArtificial intelligence is, as the name suggests, artificial and fundamentally different to human intelligence. Yet often the goal of AI is to fake human intelligence. This deceit has been there from the very beginning. We’ve been trying to fake it since Alan Turing answered the question ‘Can machines think?’ by proposing that machines pretend to be humans.Now we are starting to build AI that truly deceives us. Powerful AIs such as ChatGPT can convince us they are intelligent and blur the distinction between what is real and what is simulated. In reality, they lack true understanding, sentience and common sense. But this doesn’t mean they can’t change the world.Can AI systems ever be creative? Can they be moral? What can we do to ensure they are not harmful? In this fun and fascinating book, Professor Toby Walsh explores all the ways AI fakes it, and what this means for humanity – now and in the future.
