This unusual picture book shrinks the world's population down to a village of 100 to help children better understand who we are, where we live, how fast we are growing and more. "Thought-provoking and highly effective, this world-in-miniature will open eyes to a wider view of our planet and its human inhabitants."

In her surprising, entertaining, and persuasive new book, award-winning author and psychologist Susan Pinker shows how face-to-face contact is crucial for learning, happiness, resilience, and longevity. From birth to death, human beings are hardwired to connect to other human beings. Face-to-face contact matters: tight bonds of friendship and love heal us, help children learn, extend our lives, and make us happy. Looser in-person bonds matter, too, combining with our close relationships to form a personal “village” around us, one that exerts unique effects. Not just any social networks will do: we need the real, in-the-flesh encounters that tie human families, groups of friends, and communities together. Marrying the findings of the new field of social neuroscience with gripping human stories, Susan Pinker explores the impact of face-to-face contact from cradle to grave, from city to Sardinian mountain village, from classroom to workplace, from love to marriage to divorce. Her results are enlightening and enlivening, and they challenge many of our assumptions. Most of us have left the literal village behind and don’t want to give up our new technologies to go back there. But, as Pinker writes so compellingly, we need close social bonds and uninterrupted face-time with our friends and families in order to thrive—even to survive. Creating our own “village effect” makes us happier. It can also save our lives. Praise for The Village Effect “The benefits of the digital age have been oversold. Or to put it another way: there is plenty of life left in face-to-face, human interaction. That is the message emerging from this entertaining book by Susan Pinker, a Canadian psychologist. Citing a wealth of research and reinforced with her own arguments, Pinker suggests we should make an effort—at work and in our private lives—to promote greater levels of personal intimacy.”—Financial Times “Drawing on scores of psychological and sociological studies, [Pinker] suggests that living as our ancestors did, steeped in face-to-face contact and physical proximity, is the key to health, while loneliness is ‘less an exalted existential state than a public health risk.’ That her point is fairly obvious doesn’t diminish its importance; smart readers will take the book out to a park to enjoy in the company of others.”—The Boston Globe “A hopeful, warm guide to living more intimately in an disconnected era.”—Publishers Weekly “A terrific book . . . Pinker makes a hardheaded case for a softhearted virtue. Read this book. Then talk about it—in person!—with a friend.”—Daniel H. Pink, New York Times bestselling author of Drive and To Sell Is Human “What do Sardinian men, Trader Joe’s employees, and nuns have in common? Real social networks—though not the kind you’ll find on Facebook or Twitter. Susan Pinker’s delightful book shows why face-to-face interaction at home, school, and work makes us healthier, smarter, and more successful.”—Charles Duhigg, New York Times bestselling author of The Power of Habit: Why We Do What We Do in Life and Business “Provocative and engaging . . . Pinker is a great storyteller and a thoughtful scholar. This is an important book, one that will shape how we think about the increasingly virtual world we all live in.”—Paul Bloom, author of Just Babies: The Origins of Good and Evil From the Hardcover edition.

This is the new paperback edition of a beautiful and unique book, which explains facts about the world's population in a simple and fascinating way. Instead of unimaginable billions, it presents the whole world as a village of just 100 people. We soon find out that 22 speak a Chinese dialect and that 17 cannot read or write. We also discover the people's religions, their education, their standard of living, and much much more… This book provokes thought and elicits questions. It cannot fail to inspire children's interest in world geography, citizenship and different customs and cultures, whether they read it at home or at school.

Contributions to Statistics focuses on the processes, methodologies, and approaches involved in statistics. The book is presented to Professor P. C. Mahalanobis on the occasion of his 70th birthday. The selection first offers information on the recovery of ancillary information and combinatorial properties of partially balanced designs and association schemes. Discussions focus on combinatorial applications of the algebra of association matrices, sample size analogy, association matrices and the algebra of association schemes, and conceptual statistical experiments. The book then examines lattice sampling by means of Lahiri's sampling scheme; contributions of interpenetrating networks of samples; and apparently unconnected problems encountered in sampling work. The publication takes a look at screening processes, place of the design of experiments in the logic of scientific inference, and rarefaction. Topics include mathematical probability, scientific experience, combinatorial progress, gains and losses, criterion and scores, simple drug screening process, and screening of crop varieties. The manuscript then reviews the estimation and interpretation of gross differences and the simple response variance; partially balanced asymmetrical factorial designs; and approximation of distributions of sums of independent summands by infinitely divisible distributions. The selection is a dependable reference for statisticians and researchers interested in the processes, methodologies, and approaches employed in statistics.
