A former Wall Street quant sounds an alarm on the mathematical models that pervade modern life -- and threaten to rip apart our social fabricWe live in the age of the algorithm. Increasingly, the decisions that affect our lives--where we go to school, whether we get a car loan, how much we pay for health insurance--are being made not by humans, but by mathematical models. In theory, this should lead to greater fairness: Everyone is judged according to the same rules, and bias is eliminated.But as Cathy O'Neil reveals in this urgent and necessary book, the opposite is true. The models being used today are opaque, unregulated, and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination: If a poor student can't get a loan because a lending model deems him too risky (by virtue of his zip code), he's then cut off from the kind of education that could pull him out of poverty, and a vicious spiral ensues. Models are propping up the lucky and punishing the downtrodden, creating a "toxic cocktail for democracy." Welcome to the dark side of Big Data.Tracing the arc of a person's life, O'Neil exposes the black box models that shape our future, both as individuals and as a society. These "weapons of math destruction" score teachers and students, sort résumés, grant (or deny) loans, evaluate workers, target voters, set parole, and monitor our health.O'Neil calls on modelers to take more responsibility for their algorithms and on policy makers to regulate their use. But in the end, it's up to us to become more savvy about the models that govern our lives. This important book empowers us to ask the tough questions, uncover the truth, and demand change.From the Hardcover edition.
BONUS: This edition contains an excerpt from Mary Balogh's The Secret Mistress.Meet the Bedwyns--six brothers and sisters--men and women of passion and privilege, daring and sensuality. Enter their dazzling world of high society and breathtaking seduction...where each will seek love, fight temptation, and court scandal...and where Morgan Bedwyn, the willful youngest daughter, discovers that true love is a temptation no woman can--or should--resist. Young. Ravishing. Exquisitely marriageable. From the moment he spies Lady Morgan Bedwyn across the glittering ballroom, Gervase Ashford, Earl of Rosthorn, knows he has found the perfect instrument of his revenge.

There is only one thing standing in his way: Morgan, who has achieved the impossible--she's melted his coolly guarded heart. For Gervase, only the marriage bed will do, but Morgan simply will not have him. Thus begins a sizzling courtship where two wary hearts are about to be undone by the most scandalous passion of all: glorious, all-consuming love.
From Tim Wu, author of the award-winning The Master Switch and who coined the phrase "net neutrality"--a revelatory look at the rise of "attention harvesting," and its transformative effect on our society and our selves. Attention merchant: an industrial-scale harvester of human attention. A firm whose business model is the mass capture of attention for resale to advertisers.In nearly every moment of our waking lives, we face a barrage of advertising enticements, branding efforts, sponsored social media, commercials and other efforts to harvest our attention. Over the last century, few times or spaces have remained uncultivated by the "attention merchants," contributing to the distracted, unfocused tenor of our times. Tim Wu argues that this is not simply the byproduct of recent inventions but the end result of more than a century's growth and expansion in the industries that feed on human attention. From the pre-Madison Avenue birth of advertising to TV's golden age to our present age of radically individualized choices, the business model of "attention merchants" has always been the same. He describes the revolts that have risen against these relentless attempts to influence our consumption, from the remote control to FDA regulations to Apple's ad-blocking OS. But he makes clear that attention merchants grow ever-new heads, and their means of harvesting our attention have given rise to the defining industries of our time, changing our nature--cognitive, social, and otherwise--in ways unimaginable even a generation ago.From the Hardcover edition.

He illuminates the encroachment experienced by the tribes and the tribal conflicts over whether to fight or make peace, and explores the squalid lives of soldiers posted to the frontier and the ethical quandaries faced by generals who often sympathized with their native enemies.From the Hardcover edition.
From the acclaimed author of The Information and Chaos, here is a mind-bending exploration of time travel: its subversive origins, its evolution in literature and science, and its influence on our understanding of time itself. The story begins at the turn of the previous century, with the young H. G. Wells writing and rewriting the fantastic tale that became his first book and an international sensation: The Time Machine. It was an era when a host of forces was converging to transmute the human understanding of time, some philosophical and some technological: the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. James Gleick tracks the evolution of time travel as an idea that becomes part of contemporary culture--from Marcel Proust to Doctor Who, from Jorge Luis Borges to Woody Allen. He investigates the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.(With a color frontispiece and black-and-white illustrations throughout) From the Hardcover edition.
A leading cognitive scientist argues that a deep sense of good and evil is bred in the bone. From John Locke to Sigmund Freud, philosophers and psychologists have long believed that we begin life as blank moral slates. Many of us take for granted that babies are born selfish and that it is the role of society--and especially parents--to transform them from little sociopaths into civilized beings. In Just Babies, Paul Bloom argues that humans are in fact hardwired with a sense of morality. Drawing on groundbreaking research at Yale, Bloom demonstrates that, even before they can speak or walk, babies judge the goodness and badness of others' actions; feel empathy and compassion; act to soothe those in distress; and have a rudimentary sense of justice.Still, this innate morality is limited, sometimes tragically. We are naturally hostile to strangers, prone to parochialism and bigotry. Bringing together insights from psychology, behavioral economics, evolutionary biology, and philosophy, Bloom explores how we have come to surpass these limitations. Along the way, he examines the morality of chimpanzees, violent psychopaths, religious extremists, and Ivy League professors, and explores our often puzzling moral feelings about sex, politics, religion, and race. In his analysis of the morality of children and adults, Bloom rejects the fashionable view that our moral decisions are driven mainly by gut feelings and unconscious biases. Just as reason has driven our great scientific discoveries, he argues, it is reason and deliberation that makes possible our moral discoveries, such as the wrongness of slavery. Ultimately, it is through our imagination, our compassion, and our uniquely human capacity for rational thought that we can transcend the primitive sense of morality we were born with, becoming more than just babies.Paul Bloom has a gift for bringing abstract ideas to life, moving seamlessly from Darwin, Herodotus, and Adam Smith to The Princess Bride, Hannibal Lecter, and Louis C.K. Vivid, witty, and intellectually probing, Just Babies offers a radical new perspective on our moral lives.From the Hardcover edition.

The primary objective of this book is to study some of the research topics in the area of analysis of complex surveys which have not been covered in any book yet. It discusses the analysis of categorical data using three models: a full model, a log-linear model and a logistic regression model. It is a valuable resource for survey statisticians and practitioners in the field of sociology, biology, economics, psychology and other areas who have to use these procedures in their day-to-day work. It is also useful for courses on sampling and complex surveys at the upper-undergraduate and graduate levels. The importance of sample surveys today cannot be overstated. From voters' behaviour to fields such as industry, agriculture, economics, sociology, psychology, investigators generally resort to survey sampling to obtain an assessment of the behaviour of the population they are interested in. Many large-scale sample surveys collect data using complex survey designs like multistage stratified cluster designs. The observations using these complex designs are not independently and identically distributed - an assumption on which the classical procedures of inference are based. This means that if classical tests are used for the analysis of such data, the inferences obtained will be inconsistent and often invalid. For this reason, many modified test procedures have been developed for this purpose over the last few decades.

In this book we develop powerful techniques based on formal methods for the verification of correctness, consistency and safety properties related to dynamic reconfiguration and communication in complex distributed systems. In particular, static analysis techniques based on types and type systems are an adequate methodology considering their success in guaranteeing not only basic safety properties, but also more sophisticated ones like deadlock or lock freedom in concurrent settings. The main contributions of this book are twofold. i) We design a type system for a concurrent object-oriented calculus to statically ensure consistency of dynamic reconfigurations. ii) We define an encoding of the session pi-calculus, which models communication in distributed systems, into the standard typed pi-calculus. We use this encoding to derive properties like type safety and progress in the session pi-calculus by exploiting the corresponding properties in the standard typed pi-calculus.
This monograph treats normally hyperbolic invariant manifolds, with a focus on noncompactness. These objects generalize hyperbolic fixed points and are ubiquitous in dynamical systems. First, normally hyperbolic invariant manifolds and their relation to hyperbolic fixed points and center manifolds, as well as, overviews of history and methods of proofs are presented. Furthermore, issues (such as uniformity and bounded geometry) arising due to noncompactness are discussed in great detail with examples. The main new result shown is a proof of persistence for noncompact normally hyperbolic invariant manifolds in Riemannian manifolds of bounded geometry. This extends well-known results by Fenichel and Hirsch, Pugh and Shub, and is complementary to noncompactness results in Banach spaces by Bates, Lu and Zeng. Along the way, some new results in bounded geometry are obtained and a framework is developed to analyze ODEs in a differential geometric context. Finally, the main result is extended to time and parameter dependent systems and overflowing invariant manifolds.
