Your colleague's husband's sister can make you fat, even if you don't know her. A happy neighbor has more impact on your happiness than a happy spouse. These startling revelations of how much we truly influence one another are revealed in the studies of Dr. Christakis and Fowler, which have repeatedly made front-page news nationwide. In Connected, the authors explain why emotions are contagious, how health behaviors spread, why the rich get richer, even how we find and choose our partners. Intriguing and entertaining, Connected overturns the notion of the individual and provides a revolutionary paradigm-that social networks influence our ideas, emotions, health, relationships, behavior, politics, and much more. It will change the way we think about every aspect of our lives.

    Now thoroughly updated and revised with information about all aspects of survey research?grounded in the most current research?the new edition provides practical ?how-to? guidelines on optimally using the Internet, mail, and phone channels to your advantage.

    Advertised only by word of mouth, the book became a favorite training and counseling guide in many institutions -- government, church, business -- and colleges across the nation adopted it as an auxiliary text in a dozen different departments. Why? Perhaps it was the user-friendly way that Please Understand Me helped people find their personality style. Perhaps it was the simple accuracy of Keirsey's portraits of temperament and character types. Or perhaps it was the book's essential message: that members of families and institutions are OK, even though they are fundamentally different from each other, and that they would all do well to appreciate their differences and give up trying to change others into copies of themselves.Now: Please Understand Me IIFor the past twenty years Keirsey has continued to investigate personality differences -- to refine his theory of the four temperaments and to define the facets of character that distinguish one from another. His findings form the basis of Please Understand Me II, an updated and greatly expanded edition of the book, far more comprehensive and coherent than the original, and yet with much of the same easy accessibility. One major addition is Keirsey's view of how the temperaments differ in the intelligent roles they are most likely to develop. Each of us, he says, has four kinds of intelligence -- tactical, logistical, diplomatic, strategic -- though one of the four interests us far more than the others, and thus gets far more practice than the rest. Like four suits in a hand of cards, we each have a long suit and a short suit in what interests us and what we do well, and fortunate indeed are those whose work matches their skills. As in the original book, Please Understand Me II begins with The Keirsey Temperament Sorter, the most used personality inventory in the world. But also included is The Keirsey Four-Types Sorter, a new short questionnaire that identifies one's basic temperament and then ranks one's second, third, and fourth choices. Share this new sorter with friends and family, and get set for a lively and fascinating discussion of personal styles.

      Statistics are everywhere, as integral to science as they are to business, and in the popular media hundreds of times a day. In this age of big data, a basic grasp of statistical literacy is more important than ever if we want to separate the fact from the fiction, the ostentatious embellishments from the raw evidence -- and even more so if we hope to participate in the future, rather than being simple bystanders. In The Art of Statistics, world-renowned statistician David Spiegelhalter shows readers how to derive knowledge from raw data by focusing on the concepts and connections behind the math. Drawing on real world examples to introduce complex issues, he shows us how statistics can help us determine the luckiest passenger on the Titanic, whether a notorious serial killer could have been caught earlier, and if screening for ovarian cancer is beneficial. The Art of Statistics not only shows us how mathematicians have used statistical science to solve these problems -- it teaches us how we too can think like statisticians. We learn how to clarify our questions, assumptions, and expectations when approaching a problem, and -- perhaps even more importantly -- we learn how to responsibly interpret the answers we receive. Combining the incomparable insight of an expert with the playful enthusiasm of an aficionado, The Art of Statistics is the definitive guide to stats that every modern person needs.

    Designing successful products and services in the digital age requires a multi-disciplinary team with expertise in interaction design, visual design, industrial design, and other disciplines. It also takes the ability to come up with the big ideas that make a desirable product or service, as well as the skill and perseverance to execute on the thousand small ideas that get your design into the hands of users. It requires expertise in project management, user research, and consensus-building. This comprehensive, full-color volume addresses all of these and more with detailed how-to information, real-life examples, and exercises. Topics include assembling a design team, planning and conducting user research, analyzing your data and turning it into personas, using scenarios to drive requirements definition and design, collaborating in design meetings, evaluating and iterating your design, and documenting finished design in a way that works for engineers and stakeholders alike.

    How can you be sure which methodology is appropriate, or whether your chosen combination of methods is consistent with the theoretical perspective you want to take? This book links methodology and theory with great clarity and precision, showing students and researchers how to navigate the maze of conflicting terminology. The major epistemological stances and theoretical perspectives that colour and shape current social research are detailed and the author reveals the philosophical origins of these schools of inquiry and shows how various disciplines contribute to the practice of social research as it is known today.

    Rest assured that the book is not mere theory. Ericsson's research focuses on the real world, and he explains in detail, with examples, how all of us can apply the principles of great performance in our work or in any other part of our lives."-- Fortune Anders Ericsson has made a career studying chess champions, violin virtuosos, star athletes, and memory mavens. Peak distills three decades of myth-shattering research into a powerful learning strategy that is fundamentally different from the way people traditionally think about acquiring new abilities. Whether you want to stand out at work, improve your athletic or musical performance, or help your child achieve academic goals, Ericsson's revolutionary methods will show you how to improve at almost any skill that matters to you."The science of excellence can be divided into two eras: before Ericsson and after Ericsson. His groundbreaking work, captured in this brilliantly useful book, provides us with a blueprint for achieving the most important and life-changing work possible: to become a little bit better each day."--Dan Coyle, author of The Talent Code "Ericsson's research has revolutionized how we think about human achievement. If everyone would take the lessons of this book to heart, it could truly change the world."--Joshua Foer, author of Moonwalking with Einstein

    He reveals the astonishing new culture wars playing out in our workplaces, universities, schools and homes in the names of social justice, identity politics and intersectionality.We are living through a postmodern era in which the grand narratives of religion and political ideology have collapsed. In their place have emerged a crusading desire to right perceived wrongs and a weaponization of identity, both accelerated by the new forms of social and news media. Narrow sets of interests now dominate the agenda as society becomes more and more tribal--and, as Murray shows, the casualties are mounting.

    The principal enhancement in Java 8 was the addition of functional programming constructs to Java's object-oriented roots. Java 7, 8, and 9 also introduced language features, such as the try-with-resources statement, the diamond operator for generic types, default and static methods in interfaces, the @SafeVarargs annotation, and modules. New library features include pervasive use of functional interfaces and streams, the java.time package for manipulating dates and times, and numerous minor enhancements such as convenience factory methods for collections. In this new edition of Effective Java, Bloch updates the work to take advantage of these new language and library features, and provides specific best practices for their use. Java's increased support for multiple paradigms increases the need for best-practices advice, and this book delivers. As in previous editions, each chapter consists of several "items," each presented in the form of a short, standalone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why. Coverage includes:Updated techniques and best practices on classic topics, including objects, classes, methods, libraries, and generics How to avoid the traps and pitfalls of commonly misunderstood subtleties of the platform Focus on the language and its most fundamental libraries, such as java.lang and java.util

    The suggested strategies are supported by research and are grounded in enough theory to enable teachers to adapt them to their own situations. The author does not suggest a "set of recipes" to be followed mechanically, but gives teachers the tools they need to deal with the ever changing dynamics of teaching and learning.

    With his trademark humor and frankness, Alan Alda explains what makes the out-of-the-box techniques he developed after his years as the host of Scientific American Frontiers so effective. This book reveals what it means to be a true communicator, and how we can communicate better, in every aspect of our lives—with our friends, lovers, and families, with our doctors, in business settings, and beyond.

    But all too often when we interact with people—especially those who report to us—we simply tell them what we think they need to know. This shuts them down. To generate bold new ideas, to avoid disastrous mistakes, to develop agility and flexibility, we need to practice Humble Inquiry.Ed Schein defines Humble Inquiry as “the fine art of drawing someone out, of asking questions to which you do not know the answer, of building a relationship based on curiosity and interest in the other person.” In this seminal work, Schein contrasts Humble Inquiry with other kinds of inquiry, shows the benefits Humble Inquiry provides in many different settings, and offers advice on overcoming the cultural, organizational, and psychological barriers that keep us from practicing it.
