A unique collection of competition problems from over twenty major national and international mathematical competitions for high school students. Written for trainers and participants of contests of all levels up to the highest level, this will appeal to high school teachers conducting a mathematics club who need a range of simple to complex problems and to those instructors wishing to pose a "problem of the week", thus bringing a creative atmosphere into the classrooms. Equally, this is a must-have for individuals interested in solving difficult and challenging problems. Each chapter starts with typical examples illustrating the central concepts and is followed by a number of carefully selected problems and their solutions. Most of the solutions are complete, but some merely point to the road leading to the final solution. In addition to being a valuable resource of mathematical problems and solution strategies, this is the most complete training book on the market.

Winner of Balsillie Prize for Public Policy Winner of Donner Prize A challenge to prevailing ideas about innovation and a guide to identifying the best growth strategy for your community. Across the world, cities and regions have wasted trillions of dollars on blindly copying the Silicon Valley model of growth creation. Since the early years of the information age, we've been told that economic growth derives from harnessing technological innovation. To do this, places must create good education systems, partner with local research universities, and attract innovative hi-tech firms. We have lived with this system for decades, and the result is clear: a small number of regions and cities at the top of the high-tech industry but many more fighting a losing battle to retain economic dynamism. But are there other models that don't rely on a flourishing high-tech industry? In Innovation in Real Places, Dan Breznitz argues that there are. The purveyors of the dominant ideas on innovation have a feeble understanding of the big picture on global production and innovation. They conflate innovation with invention and suffer from techno-fetishism. In their devotion to start-ups, they refuse to admit that the real obstacle to growth for most cities is the overwhelming power of the real hubs, which siphon up vast amounts of talent and money. Communities waste time, money, and energy pursuing this road to nowhere. Breznitz proposes that communities instead focus on where they fit in the four stages in the global production process. Some are at the highest end, and that is where the Clevelands, Sheffields, and Baltimores are being pushed toward. But that is bad advice. Success lies in understanding the changed structure of the global system of production and then using those insights to enable communities to recognize their own advantages, which in turn allows to them to foster surprising forms of specialized innovation. As he stresses, all localities have certain advantages relative to at least one stage of the global production process, and the trick is in recognizing it. Leaders might think the answer lies in high-tech or high-end manufacturing, but more often than not, they're wrong. Innovation in Real Places is an essential corrective to a mythology of innovation and growth that too many places have bought into in recent years. Best of all, it has the potential to prod local leaders into pursuing realistic and regionally appropriate models for growth and innovation.

In the tradition of Octavia Butler, here is radical self-help, society-help, and planet-help to shape the futures we want. Change is constant. The world, our bodies, and our minds are in a constant state of flux. They are a stream of ever-mutating, emergent patterns. Rather than steel ourselves against such change, Emergent Strategy teaches us to map and assess the swirling structures and to read them as they happen, all the better to shape that which ultimately shapes us, personally and politically. A resolutely materialist spirituality based equally on science and science fiction: a wild feminist and afro-futurist ride! adrienne maree brown, co-editor of Octavia’s Brood: Science Fiction from Social Justice Movements, is a social justice facilitator, healer, and doula living in Detroit.

How to Globalize to Survive in the New Economy At a time in which globalization impacts corporate strategy as never before, corporate leaders are challenged to consider all the implications of a new global economy. Characterized by a myriad of competing forces, this new global economy is highlighted by unprecedented advances in technology of all kinds. With such unrelenting change blurring the view, corporate leaders need the benefit of the best thinking in order to focus on the right global strategies.World Viewoffers just such thinking, featuring examples of strategies and best practices used by successful companies worldwide in moving toward global markets. In his introduction to this collection ofHarvard Business Reviewarticles, editor Jeffrey Garten pinpoints five emerging themes: * Operating in a global market requires CEOs to rethink every aspect of their strategies. * The best strategies require that organizations gather massive amounts of information and process it effectively. * Companies that succeed on a global scale are constant innovators, learning and implementing simultaneously. * Great global companies create cultures conducive to extensive internal and external collaboration and networking. * Radical change brings unprecedented opportunity to capture markets and enhance shareholder value. Seeing globalization through the eyes of leading thinkers and executives who have mastered its challenges,World Viewpresents forward-thinking insights for corporate leaders determined to succeed in the always-new and uncertain global economy.
