Frances E. Jensen, a mother, teacher, researcher, and internationally known expert in neurology, introduces us to the mystery and magic of the teen brain. One of the first books to focus exclusively on the neurological development of adolescents, The Teenage Brain presents new findings, dispels widespread myths, and provides practical suggestions for negotiating this difficult and dynamic life stage for both adults and adolescents.Interweaving easy-to-follow scientific data with anecdotes drawn from her experiences as a parent, clinician, and public speaker, Dr. Jensen explores adolescent brain functioning and development, including learning and memory, and investigates the impact of influences such as drugs, multitasking, sleep, and stress. The Teenage Brain reveals how: Adolescents may not be as resilient to the effects of drugs as we previously thought. Occasional use of marijuana has been shown to cause lingering memory problems, and long-term use can affect later adulthood I.Q. Multi-tasking causes divided attention and can reduce learning ability. Emotionally stressful situations in adolescence can have permanent effects on mental health, and may lead to higher risk for certain neuropsychiatric disorders such as depression.Rigorous yet accessible, warm yet direct, The Teenage Brain sheds new light on young adults, and provides practical suggestions for how parents, schools, and even the legal system can better help them during this crucial period.

    The most common operation done with sed is substitution, replacing one block of text with another. awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts. This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk, where POSIX standardized a new variable, CONVFMT, and new functions, toupper() and tolower(). The CONVFMT variable specifies the conversion format to use when converting numbers to strings (awk used to use OFMT for this purpose). The toupper() and tolower() functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case. In addition, this edition covers GNU sed, newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk (gawk), covers mawk, an additional freely available implementation of awk, and briefly discusses three commercial versions of awk, MKS awk, Thompson Automation awk (tawk), and Videosoft (VSAwk).

    One of the greatest partnerships in the history of science, Kahneman and Tversky’s extraordinary friendship incited a revolution in Big Data studies, advanced evidence-based medicine, led to a new approach to government regulation, and made much of Michael Lewis’s own work possible. In The Undoing Project, Lewis shows how their Nobel Prize–winning theory of the mind altered our perception of reality.

    The Cave and the Light is a magisterial account of how the two greatest thinkers of the ancient world, Plato and Aristotle, laid the foundations of Western culture—and how their rivalry shaped the essential features of our culture down to the present day.   Plato came from a wealthy, connected Athenian family and lived a comfortable upper-class lifestyle until he met an odd little man named Socrates, who showed him a new world of ideas and ideals. Socrates taught Plato that a man must use reason to attain wisdom, and that the life of a lover of wisdom, a philosopher, was the pinnacle of achievement. Plato dedicated himself to living that ideal and went on to create a school, his famed Academy, to teach others the path to enlightenment through contemplation.   However, the same Academy that spread Plato’s teachings also fostered his greatest rival. Born to a family of Greek physicians, Aristotle had learned early on the value of observation and hands-on experience. Rather than rely on pure contemplation, he insisted that the truest path to knowledge is through empirical discovery and exploration of the world around us. Aristotle, Plato’s most brilliant pupil, thus settled on a philosophy very different from his instructor’s and launched a rivalry with profound effects on Western culture.   The two men disagreed on the fundamental purpose of the philosophy. For Plato, the image of the cave summed up man’s destined path, emerging from the darkness of material existence to the light of a higher and more spiritual truth. Aristotle thought otherwise. Instead of rising above mundane reality, he insisted, the philosopher’s job is to explain how the real world works, and how we can find our place in it. Aristotle set up a school in Athens to rival Plato’s Academy: the Lyceum. The competition that ensued between the two schools, and between Plato and Aristotle, set the world on an intellectual adventure that lasted through the Middle Ages and Renaissance and that still continues today.   From Martin Luther (who named Aristotle the third great enemy of true religion, after the devil and the Pope) to Karl Marx (whose utopian views rival Plato’s), heroes and villains of history have been inspired and incensed by these two master philosophers—but never outside their influence.   Accessible, riveting, and eloquently written, The Cave and the Light provides a stunning new perspective on the Western world, certain to open eyes and stir debate.Praise for The Cave and the Light   “A sweeping intellectual history viewed through two ancient Greek lenses . . . breezy and enthusiastic but resting on a sturdy rock of research.”—Kirkus Reviews   “Examining mathematics, politics, theology, and architecture, the book demonstrates the continuing relevance of the ancient world.”—Publishers Weekly  “A fabulous way to understand over two millennia of history, all in one book.”—Library Journal  “Entertaining and often illuminating.”—The Wall Street JournalFrom the Hardcover edition.

    Language is humanity's most spectacular open-source project, and the internet is making our language change faster and in more interesting ways than ever before. Internet conversations are structured by the shape of our apps and platforms, from the grammar of status updates to the protocols of comments and @replies. Linguistically inventive online communities spread new slang and jargon with dizzying speed. What's more, social media is a vast laboratory of unedited, unfiltered words where we can watch language evolve in real time.Even the most absurd-looking slang has genuine patterns behind it. Internet linguist Gretchen McCulloch explores the deep forces that shape human language and influence the way we communicate with one another. She explains how your first social internet experience influences whether you prefer "LOL" or "lol," why ~sparkly tildes~ succeeded where centuries of proposals for irony punctuation had failed, what emoji have in common with physical gestures, and how the artfully disarrayed language of animal memes like lolcats and doggo made them more likely to spread.Because Internet is essential reading for anyone who's ever puzzled over how to punctuate a text message or wondered where memes come from. It's the perfect book for understanding how the internet is changing the English language, why that's a good thing, and what our online interactions reveal about who we are.

    We're rebelling against technology that's too complicated, DVD players with too many menus, and software accompanied by 75-megabyte "read me" manuals. The iPod's clean gadgetry has made simplicity hip. But sometimes we find ourselves caught up in the simplicity paradox: we want something that's simple and easy to use, but also does all the complex things we might ever want it to do. In The Laws of Simplicity, John Maeda offers ten laws for balancing simplicity and complexity in business, technology, and design—guidelines for needing less and actually getting more.Maeda—a professor in MIT's Media Lab and a world-renowned graphic designer—explores the question of how we can redefine the notion of "improved" so that it doesn't always mean something more, something added on.Maeda's first law of simplicity is "Reduce." It's not necessarily beneficial to add technology features just because we can. And the features that we do have must be organized (Law 2) in a sensible hierarchy so users aren't distracted by features and functions they don't need. But simplicity is not less just for the sake of less. Skip ahead to Law 9: "Failure: Accept the fact that some things can never be made simple." Maeda's concise guide to simplicity in the digital age shows us how this idea can be a cornerstone of organizations and their products—how it can drive both business and technology. We can learn to simplify without sacrificing comfort and meaning, and we can achieve the balance described in Law 10. This law, which Maeda calls "The One," tells us: "Simplicity is about subtracting the obvious, and adding the meaningful."

    Extreme market volatility, pandemics, industry change, supply-chain disruption. The list of potential threats and strategic challenges seems to be growing exponentially. At the same time, the laborious processes used by many firms to develop a workable strategy often feel overly bureaucratic and behind the curve. There is no question that strategic decision-making has become more challenging and complex. In fact, many companies seem to have given up on strategy altogether. In Better, Simpler Strategy, Harvard Business School professor Felix Oberholzer-Gee provides executives with a simple tool to cut through technological complexity and market uncertainties. The Value Stick, based on proven economic mechanics, is an extraordinarily powerful tool that helps executives decide where to focus their attention and how to deepen their firm's competitive advantage. How does the Value Stick work? It provides a way of measuring two fundamental forces that lead to value creation and capture-the customer's willingness to pay and the employee's willingness to sell their services to the firm. For example, increasing product quality increases a customer's willingness to pay. And firms can redesign work processes or conditions or integrate other benefits (besides income) to lower employees' willingness to sell their services to firms and still retain them. With many examples across industries (based on Harvard Business School case studies), Oberholzer-Gee shows these value dynamics in action and explains how looking at and adjusting these measures using one tool, the Value Stick, enables firms to gauge and improve their strategies and operations. Based on the author's successful strategy course, Better, Simpler Strategy will become every business strategist's must-have guide for making better strategic decisions and gaining competitive advantage"--

    What if everything you knew about education was wrong? is just a title. Of course, you probably think a great many things that aren't wrong. The aim of the book is to help you 'murder your darlings'. David Didau will question your most deeply held assumptions about teaching and learning, expose them to the fiery eye of reason and see if they can still walk in a straight line after the experience. It seems reasonable to suggest that only if a theory or approach can withstand the fiercest scrutiny should it be encouraged in classrooms. David makes no apologies for this; why wouldn't you be sceptical of what you're told and what you think you know? As educated professionals, we ought to strive to assemble a more accurate, informed or at least considered understanding of the world around us. Here, David shares with you some tools to help you question your assumptions and assist you in picking through what you believe. He will stew findings from the shiny white laboratories of cognitive psychology, stir in a generous dash of classroom research and serve up a side order of experience and observation. Whether you spit it out or lap it up matters not. If you come out the other end having vigorously and violently disagreed with him, you'll at least have had to think hard about what you believe. The book draws on research from the field of cognitive science to expertly analyse some of the unexamined meta-beliefs in education. In Part 1; 'Why we're wrong', David dismantles what we think we know; examining cognitive traps and biases, assumptions, gut feelings and the problem of evidence. Part 2 delves deeper - 'Through the threshold' - looking at progress, liminality and threshold concepts, the science of learning, and the difference between novices and experts. In Part 3, David asks us the question 'What could we do differently?' and offers some considered insights into spacing and interleaving, the testing effect, the generation effect, reducing feedback and why difficult is desirable. While Part 4 challenges us to consider 'What else might we be getting wrong?'; cogitating formative assessment, lesson observation, grit and growth, differentiation, praise, motivation and creativity.

    Starting with Alexander Graham Bell's revolutionary "harmonic telegraph," by the middle of the twentieth century the phone system had grown into something extraordinary, a web of cutting-edge switching machines and human operators that linked together millions of people like never before. But the network had a billion-dollar flaw, and once people discovered it, things would never be the same.Exploding the Phone tells this story in full for the first time. It traces the birth of long-distance communication and the telephone, the rise of AT&T's monopoly, the creation of the sophisticated machines that made it all work, and the discovery of Ma Bell's Achilles' heel. Phil Lapsley expertly weaves together the clandestine underground of "phone phreaks" who turned the network into their electronic playground, the mobsters who exploited its flaws to avoid the feds, the explosion of telephone hacking in the counterculture, and the war between the phreaks, the phone company, and the FBI.The product of extensive original research, Exploding the Phone is a ground-breaking, captivating book.

    Most of the time this math works quietly behind the scenes . . . until it doesn't. All sorts of seemingly innocuous mathematical mistakes can have significant consequences.Math is easy to ignore until a misplaced decimal point upends the stock market, a unit conversion error causes a plane to crash, or someone divides by zero and stalls a battleship in the middle of the ocean.Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

    When combined with powerful voice AI, the results are utterly convincing.So-called 'Deep Fakes' are not only a real threat for democracy but they take the manipulation of voters to new levels. They will also affect ordinary people. This crisis of misinformation we are facing has been dubbed the 'Infocalypse'.Using her expertise from working in the field, Nina Schick reveals shocking examples of Deep Fakery and explains the dangerous political consequences of the Infocalypse, both in terms of national security and what it means for public trust in politics. She also unveils what it means for us as individuals, how Deep Fakes will be used to intimidate and to silence, for revenge and fraud, and how unprepared governments and tech companies are.As a political advisor to select technology firms, Schick tells us what we need to do to prepare and protect ourselves. Too often we build the cool technology and ignore what bad guys can do with it before we start playing catch-up. But when it comes to Deep Fakes, we urgently need to be on the front foot.
