Ruidos en la web: Cómo se informan los adolescentes en la era digital
by Roxana MorduchowiczEste es un libro sobre los adolescentes. También sobre las tecnologías. Y sobre ciudadanía y política. Desde estos cuatro ejes y analiza las serias dificultades que tienen los jóvenes para buscar, procesar, seleccionar, evaluar y utilizar el enorme caudal de información que circula hoy en internet. Adolescencia, tecnología, educación y cultura ciudadana: sobre estos cuatro ejes se asienta Ruidos en la web para explorar un interrogante crucial: cómo se informan los jóvenes en un universo de saberes sin límites. La pregunta es asediada a partir de múltiples enfoques: desde la forma en que los chicos utilizan internet para las tareas escolares, los nuevos hábitos propios de esta era tecnológica, su impacto en el espacio doméstico, el cambio en el concepto de autoridad cuando se trata de acudir a una fuente de información, la dificultad para distinguir entre contenidos falsos y genuinos. Y de esta problemática se desprende la preocupación por el modo en que se está formando la futura dirigencia y sus consecuencias sobre la democracia. Con un estilo ameno que no va en desmedro del rigor académico, Roxana Morduchowicz, especialista en cultura juvenil y en la relación de los chicos con las pantallas e internet, brinda un panorama de la situación, desmitifica postulados poco consistentes, se resiste a los clichés y pone en agenda un tema de interés universal.

Rule Based Systems for Big Data
by Han Liu Alexander Gegov Mihaela CoceaThe ideas introduced in this book explore the relationships among rule based systems, machine learning and big data. Rule based systems are seen as a special type of expert systems, which can be built by using expert knowledge or learning from real data. The book focuses on the development and evaluation of rule based systems in terms of accuracy, efficiency and interpretability. In particular, a unified framework for building rule based systems, which consists of the operations of rule generation, rule simplification and rule representation, is presented. Each of these operations is detailed using specific methods or techniques. In addition, this book also presents some ensemble learning frameworks for building ensemble rule based systems.
Rule of the Robots: How Artificial Intelligence Will Transform Everything
by Martin FordThe New York Times–bestselling author of Rise of the Robots shows what happens as AI takes over our lives If you have a smartphone, you have AI in your pocket. AI is impossible to avoid online. And it has already changed everything from how doctors diagnose disease to how you interact with friends or read the news. But in Rule of the Robots, Martin Ford argues that the true revolution is yet to come. In this sequel to his prescient New York Times bestseller Rise of the Robots, Ford presents us with a striking vision of the very near future. He argues that AI is a uniquely powerful technology that is altering every dimension of human life, often for the better. For example, advanced science is being done by machines, solving devilish problems in molecular biology that humans could not, and AI can help us fight climate change or the next pandemic. It also has a capacity for profound harm. Deep fakes—AI-generated audio or video of events that never happened—are poised to cause havoc throughout society. AI empowers authoritarian regimes like China with unprecedented mechanisms for social control. And AI can be deeply biased, learning bigoted attitudes from us and perpetuating them. In short, this is not a technology to simply embrace, or let others worry about. The machines are coming, and they won&’t stop, and each of us needs to know what that means if we are to thrive in the twenty-first century. And Rule of the Robots is the essential guide to all of it: both AI and the future of our economy, our politics, our lives.
Rule of the Robots: How Artificial Intelligence Will Transform Everything
by Martin FordIn this sequel to his prescient New York Times bestseller Rise of the Robots, Martin Ford presents us with a striking vision of the very near future. He argues that AI is a uniquely powerful technology, a kind of "electricity of intelligence" that is altering every dimension of human life, often for the better with advanced science being done by machines who can solve problems humans can not. AI has the potential to help us fight climate change or the next pandemic, but it also has a capacity for profound harm. Deep fakes-AI-generated audio or video of events that never happened-are poised to cause havoc throughout society. AI empowers authoritarian regimes like China with unprecedented mechanisms for social control. And AI can be deeply biased, learning bigoted attitudes from the data used to train algorithms and perpetuating them. Hard-hitting and thought-provoking, covering everything from self-driving cars to the history of deep learning to apps for diagnosing skin cancer, Rule of the Robots challenges our fears and preconceptions about artificial intelligence. Ford argues that AI is here to stay and the real question is not how to stop it, but how to control its negative potential and harness its power for good as AI transforms our economy, our politics, and our lives.

The Rule of Thoughts (The Mortality Doctrine #2)
by James DashnerFrom James Dashner, the #1 New York Times bestselling author of the Maze Runner series comes The Rule of Thoughts, the exciting sequel to The Eye of Minds. Michael completed the Path. What he found at the end turned everything he'd ever known about his life--and the world--completely upside down. He barely survived. But it was the only way VirtNet Security knew to find the cyber-terrorist Kaine--and to make the Sleep safe for gamers once again. And, the truth Michael discovered about Kaine is more complex than they anticipated, and more terrifying than even the worst of their fears. Kaine is a tangent, a computer program that has become sentient. And Michael's completing the Path was the first stage in turning Kaine's master plan, the Mortality Doctrine, into a reality. The Mortality Doctrine will populate Earth entirely with human bodies harboring tangent minds. Any gamer who sinks into the VirtNet risks coming out with a tangent intelligence in control of their body. And the takeover has already begun.
The Rule of Three
by Eric WaltersOne shocking afternoon, computers around the globe shut down in a viral catastrophe. At sixteen-year-old Adam Daley's high school, the problem first seems to be a typical electrical outage, until students discover that cell phones are down, municipal utilities are failing, and a few computer-free cars like Adam's are the only vehicles that function. Driving home, Adam encounters a storm tide of anger and fear as the region becomes paralyzed. Soon--as resources dwindle, crises mount, and chaos descends--he will see his suburban neighborhood band together for protection. And Adam will understand that having a police captain for a mother and a retired government spy living next door are not just the facts of his life but the keys to his survival, in The Rule of Three by Eric Walters.

Rules for Revolutionaries: How Big Organizing Can Change Everything
by Zack Exley Becky BondLessons from the groundbreaking grassroots campaign that helped launch a new political revolution Rules for Revolutionaries is a bold challenge to the political establishment and the "rules" that govern campaign strategy. It tells the story of a breakthrough experiment conducted on the fringes of the Bernie Sanders presidential campaign: A technology-driven team empowered volunteers to build and manage the infrastructure to make seventy-five million calls, launch eight million text messages, and hold more than one-hundred thousand public meetings--in an effort to put Bernie Sanders's insurgent campaign over the top. Bond and Exley, digital iconoclasts who have been reshaping the way politics is practiced in America for two decades, have identified twenty-two rules of "Big Organizing" that can be used to drive social change movements of any kind. And they tell the inside story of one of the most amazing grassroots political campaigns ever run. Fast-paced, provocative, and profound, Rules for Revolutionaries stands as a liberating challenge to the low expectations and small thinking that dominates too many advocacy, non-profit, and campaigning organizations--and points the way forward to a future where political revolution is truly possible.

The Rules of Contagion: Why Things Spread--And Why They Stop
by Adam KucharskiFrom ideas and infections to financial crises and fake news, an "utterly timely" look at why the science of outbreaks is the science of modern lifeThese days, whenever anything spreads, whether it's a YouTube fad or a political rumor, we say it went viral. But how does virality actually work? In The Rules of Contagion, epidemiologist Adam Kucharski explores topics including gun violence, online manipulation, and, of course, outbreaks of disease to show how much we get wrong about contagion, and how astonishing the real science is. Why did the president retweet a Mussolini quote as his own? Why do financial bubbles take off so quickly? Why are disinformation campaigns so effective? And what makes the emergence of new illnesses -- such as MERS, SARS, or the coronavirus disease COVID-19 -- so challenging? By uncovering the crucial factors driving outbreaks, we can see how things really spread -- and what we can do about it.Whether you are an author seeking an audience, a defender of truth, or simply someone interested in human social behavior, The Rules of Contagion is an essential guide to modern life.
