    As gripping as CSI and as eye-opening as Mary Roach’s Stiff, Carney’s The Red Market sheds a blazing new light on the disturbing, billion-dollar business of trading in human body parts, bodies, and child trafficking, raising issues and exposing corruptions almost too bizarre and shocking to imagine.

    We see how they rebrand themselves as saviors of the poor; how they lavishly reward "thought leaders" who redefine "change" in winner-friendly ways; and how they constantly seek to do more good, but never less harm. We hear the limousine confessions of a celebrated foundation boss; witness an American president hem and haw about his plutocratic benefactors; and attend a cruise-ship conference where entrepreneurs celebrate their own self-interested magnanimity.Giridharadas asks hard questions: Why, for example, should our gravest problems be solved by the unelected upper crust instead of the public institutions it erodes by lobbying and dodging taxes? He also points toward an answer: Rather than rely on scraps from the winners, we must take on the grueling democratic work of building more robust, egalitarian institutions and truly changing the world. A call to action for elites and everyday citizens alike.

     Who’d be a copper? follows Jonathan Nicholas in his transition from a long-haired world traveller to becoming one of ‘Thatcher’s army’ on the picket lines of the 1984 miner’s dispute and beyond. His first years in the police were often chaotic and difficult, and he was very nearly sacked for not prosecuting enough people. Working at the sharp end of inner-city policing for the entire thirty years, Jonathan saw how politics interfered with the job; from the massaging of crime figures to personal petty squabbles with senior officers. His last ten years were the oddest, from being the best cop in the force to repeatedly being told that he faced dismissal. This astonishing true story comes from deep in the heart of British inner-city policing and is a revealing insight into what life is really like for a police officer, amid increasing budget cuts, bizarre Home Office ideas and stifling political correctness. “I can write what I like, even if it brings the police service into disrepute, because I don’t work for them anymore!” says Jonathan Nicholas. Who’d be a copper? is a unique insight into modern policing that will appeal to fans of autobiographies, plus those interested in seeing what really happens behind the scenes of the UK police."I HAVE BOUGHT YOUR BOOK."  TW,  Sir Thomas Winsor, WS HMCIC"A WEALTH OF ANECDOTES.

    Franklin Evans had watched every war movie John Wayne ever made, sometimes several times over. When the “Duke” led his men, war was exciting and heroes were made as they ruggedly fought and predictably won each battle. But when Evans’ high school friend and real-life hero Glenn was killed in Vietnam, war became real and personal for Evans, and he felt a tremendous obligation to the buddy who gave his life in that faraway jungle. At the tender age of nineteen, Evans voluntarily enlisted in the U.S. Army and left for basic training in early December of 1966. Before long, he was deeply entrenched in a treacherous war, far removed from his innocent and carefree youth. He had to learn not only to survive but also to muster the bravery to lead others in combat as he was thrust from adolescence into adulthood. It has taken Evans more than thirty-five years to begin to heal the physical and emotional wounds that kept him from sharing his intensely personal story. From his depiction of the picturesque aerial view of Cam Rahn Bay to that of the barbed wire, metal planking, and squat huts housing weapons of death and destruction, Evans’s Stand To …provides a vividly detailed glimpse into what it was like to become a man on the battlefields of Vietnam.

    So wrong that a chimpanzee choosing answers at random will consistently outguess teachers, journalists, Nobel laureates, and investment bankers.In Factfulness, Professor of International Health and global TED phenomenon Hans Rosling, together with his two long-time collaborators, Anna and Ola, offers a radical new explanation of why this happens. They reveal the ten instincts that distort our perspective—from our tendency to divide the world into two camps (usually some version of us and them) to the way we consume media (where fear rules) to how we perceive progress (believing that most things are getting worse).Our problem is that we don’t know what we don’t know, and even our guesses are informed by unconscious and predictable biases.It turns out that the world, for all its imperfections, is in a much better state than we might think. That doesn’t mean there aren’t real concerns. But when we worry about everything all the time instead of embracing a worldview based on facts, we can lose our ability to focus on the things that threaten us most.Inspiring and revelatory, filled with lively anecdotes and moving stories, Factfulness is an urgent and essential book that will change the way you see the world and empower you to respond to the crises and opportunities of the future.

    We put out fires. We deal with emergencies. We stay downstream, handling one problem after another, but we never make our way upstream to fix the systems that caused the problems ... [This book] probes the psychological forces that push us downstream--including 'problem blindness,' which can leave us oblivious to serious problems in our midst. And Heath introduces us to the thinkers who have overcome these obstacles and scored ... victories by switching to an upstream mindset.

    Many people have been helped by this valuable book, first published five years ago, which addresses those of us who desperately want to change but can’t stop behaving in ways that hurt us and those we love. The authors assure us that we can change these hurtful patterns. Drs. Stoop and Masteller believe you can move beyond failure to forgiveness, cancelling the indebtedness of those who have hurt you. But before you can begin the process of forgiveness, you need to understand the roots of your pain, through exploring the family patterns that perpetuate dysfunction. When you understand your family of origin, you will be able to take the essential step of forgiveness.

    Understanding someone’s pattern of behavior is the key to successful communication. Erikson breaks down the four kinds of behavior types—Reds who are dominant and commanding, Yellows who are social and optimistic, Greens who are laid back and friendly, and Blues who are analytical and precise—and explains how to identify and interact with each type of person. Instead of being bogged down with overly technical categorizations, the simple four color system allows you to speedily identify a friend or coworker and adjust how you speak and share with them.Surrounded by Idiots is full of practical information for interacting with people based on their color, including the strengths and weaknesses of all the profiles, how to give positive and negative feedback to each, and the best way to word an email when writing to someone with a different profile.

    In a way, you already know them. Only you don’t – not really. In a sense, they are you. Only they’re not entirely. They inform and shape the most important decisions in your life. But you’re almost certainly unaware of their intervention. They are the Ten Types of Human. Who are they? What are they for? How did they get into your head? We want to believe that there are some things we would never do. We want to believe that there are others we always would. But how can we be sure? What are our limits? Do we have limits?The answer lies with the Ten Types of Human: the people we become when we are faced with life's most difficult decisions. But who or what are these Types? Where do they come from? How did they get into our heads?The Ten Types of Human is a pioneering examination of human nature. It looks at the best and worst that human beings are capable of, and asks why. It explores the frontiers of the human experience, excavating the forces that shape our thoughts and actions in extreme situations. It begins in a courtroom and journeys across four continents and through the lives of some exceptional people, in search of answers.Mixing cutting-edge neuroscience, social psychology and visceral true stories, The Ten Types of Human is at once a provocation and a roadmap of the hidden parts of us. It is a book to inspire; to refashion our understanding of our many selves and semblances; and ultimately to find fresh ways to be free.

     The world is at a turning point similar to the fall of communism. Then, many focused on the collapse itself, and failed to see that a bigger trend, globalization, was about to take hold. The benefits of globalization--through the freer flow of money, people, ideas, and trade--have been many. But rather than a world that is flat, what has emerged is one of jagged peaks and rough, deep valleys characterized by wealth inequality, indebtedness, political recession, and imbalances across the world's economies. These peaks and valleys are undergoing what Michael O'Sullivan calls "the levelling"--a major transition in world economics, finance, and power. What's next is a levelling-out of wealth between poor and rich countries, of power between nations and regions, of political accountability from elites to the people, and of institutional power away from central banks and defunct twentieth-century institutions such as the WTO and the IMF.O'Sullivan then moves to ways we can develop new, pragmatic solutions to such critical problems as political discontent, stunted economic growth, the productive functioning of finance, and political-economic structures that serve broader needs.The Levelling comes at a crucial time in the rise and fall of nations. It has special importance for the US as its place in the world undergoes radical change--the ebbing of influence, profound questions over its economic model, societal decay, and the turmoil of public life.

    The Bank's model--providing collateral-free micro-loans for self-employment to millions of women villagers in Bangladesh--has inspired and shaped the thinking of economists, policy makers, business people, development workers and a generation of social entrepreneurs. Both liberal and conservative policy circles have championed the Bank's ability to transform the lives of its clients and help them escape the vicious cycle of deep economic hardship. Drawing upon interviews with villagers, development workers, economists, and the Bank's founder Muhammad Yunus--a recipient of numerous humanitarian awards--the book shows how the Grameen Bank grew from an experiment in one village to an organization that lends billions of dollars in small individual loans.

    In this book legendary global business consultant Vijay Mahajan reveals this remarkable marketplace in all its richness and complexity, and helps companies understand the massive opportunity it presents.

    From the New York Times bestselling author of Chasing the Scream and Lost Connections comes a groundbreaking examination of why this is happening--and how to get our attention back. "The book the world needs in order to win the war on distraction."--Adam Grant, author of Think Again"Read this book to save your mind."--Susan Cain, author of QuietIn the United States, teenagers can focus on one task for only sixty-five seconds at a time, and office workers average only three minutes. Like so many of us, Johann Hari was finding that constantly switching from device to device and tab to tab was a diminishing and depressing way to live. He tried all sorts of self-help solutions--even abandoning his phone for three months--but nothing seemed to work. So Hari went on an epic journey across the world to interview the leading experts on human attention--and he discovered that everything we think we know about this crisis is wrong.We think our inability to focus is a personal failure to exert enough willpower over our devices. The truth is even more disturbing: our focus has been stolen by powerful external forces that have left us uniquely vulnerable to corporations determined to raid our attention for profit. Hari found that there are twelve deep causes of this crisis, from the decline of mind-wandering to rising pollution, all of which have robbed some of our attention. In Stolen Focus, he introduces readers to Silicon Valley dissidents who learned to hack human attention, and veterinarians who diagnose dogs with ADHD. He explores a favela in Rio de Janeiro where everyone lost their attention in a particularly surreal way, and an office in New Zealand that discovered a remarkable technique to restore workers' productivity.Crucially, Hari learned how we can reclaim our focus--as individuals, and as a society--if we are determined to fight for it. Stolen Focus will transform the debate about attention and finally show us how to get it back.
