Celtel was founded in Europe by an African expatriate, the Sudanese Mo Ibrahim, who went from being the son of a humble clerk to running one of the continent’s most successful mobile operators. His work in Britain led him to become a senior figure in UK mobile operator BT Celtel before launching his own company. Against all the odds, he and the international team he put together, convinced skeptical international bankers to invest in the company and demonstrated that the African continent was a place where money could be made. Celtel went from being a start-up that could barely afford to bid for new licences to acquiring the continent’s largest mobile operator in Nigeria for a billion dollars five years later. Although Africa is not entirely the land of civil war and famine seen nightly on TV screens across the world, it is probably one of the toughest places on the planet to do business. In countries with almost no infrastructure, Celtel built networks and sold phones to consumers clamouring to buy their product. Through making a number of technical innovations, they took the mobile from being a product only for the elite, to a position where nearly everyone could afford access to it. More than in the developed world, access to mobile phones in Africa has begun to change how life is led. It has had an impact on people’s personal lives, the way business is done, and even on politics.

Walking upright on two feet is a uniquely human skill. It defines us as a species. It enabled us to walk out of Africa and to spread as far as Alaska and Australia. It freed our hands and freed our minds. We put one foot in front of the other without thinking - yet how many of us know how we do that, or appreciate the advantages it gives us? In this hymn to walking, neuroscientist Shane O'Mara invites us to marvel at the benefits it confers on our bodies and minds. In Praise of Walking celebrates this miraculous ability. Incredibly, it is a skill that has its evolutionary origins millions of years ago, under the sea. And the latest research is only now revealing how the brain and nervous system performs the mechanical magic of balancing, navigating a crowded city, or running our inner GPS system. Walking is good for our muscles and posture; it helps to protect and repair organs, and can slow or turn back the ageing of our brains. With our minds in motion we think more creatively, our mood improves and stress levels fall. Walking together to achieve a shared purpose is also a social glue that has contributed to our survival as a species. As our lives become increasingly sedentary, we risk all this. We must start walking again, whether it's up a mountain, down to the park, or simply to school and work. We, and our societies, will be better for it.

Tracks the evolution of the international cellular industry from the late 1970s to the present. The development of the mobile-phone industry into what we know today required remarkable cooperation between companies, governments, and industrial sectors. Companies developing cellular infrastructure, cellular devices, cellular network services, and eventually software and mobile semiconductors had to cooperate, not simply compete, with each other. In this global history of the mobile-phone industry, Daniel D. Garcia-Swartz and Martin Campbell-Kelly examine its development in the United States, Europe, Japan, and several emerging economies, including China and India. They present the evolution of mobile phones from the perspective of vendors of telephone equipment and network operators, users whose lives have been transformed by mobile phones, and governments that have fostered specific mobile-phone standards. Cellular covers the technical aspects of the cellphone, as well as its social and political impact. Beginning with the 1980s, the authors trace the development of closed (proprietary) and open (available to all) cellular standards, the impact of network effects as cellular adoption increased, major technological changes affecting mobile phone hardware, and the role of national governments in shaping the industry. The authors also consider the changing roles that cellular phones have played in the everyday lives of people around the world and the implications 5G technology may have for the future. Finally, they offer statistics on how quickly the cellular industry grew in different regions of the world and how firms competed in those various markets. Cellular is published in the History of Computing Series. This distinguished series has played a major role in defining scholarship in the history of computing. Hallmarks of the series are its technical detail and interpretation of primary source materials.

The vast amount of information that must be considered to solve inherently ill-structured and complex strategic problems creates a need for tools and techniques to help decision-makers recognize the complexity of this process and develop a rational model for strategy evaluation. Decision Making Theories and Practices from Analysis to Strategy is a definitive focus on analytical strategic decision-making. This work is comprised of sophisticated tools and methodologies developed by researchers and vendors to improve decision making for business strategy. Extracting from a wide range of disciplines, including accounting, finance, information systems, international management, marketing, organizational management, operations research, production and operations management, and strategic management, this volume provides a conceptual and a utilitarian guide to decision making, perfect for both researchers and practicing professionals alike.

From the Royal Society, a peerless collection of all-new science writing Bill Bryson, who explored all - or at least a great deal of - current scientific knowledge inA Short History of Nearly Everything, now turns his attention to the history of that knowledge. As editor ofSeeing Further, he has rounded up an extraordinary roster of scientists who write and writers who know science in order to celebrate 350 years of the Royal Society, Britain's scientific national academy. The result is an encyclopedic survey of the history, philosophy and current state of science, written in an accessible and inspiring style by some of today's most important writers. The contributors include Margaret Atwood, Steve Jones, Richard Dawkins, James Gleick, Richard Holmes, and Neal Stephenson, among many others, on subjects ranging from metaphysics to nuclear physics, from the threatened endtimes of flu and climate change to our evolving ideas about the nature of time itself, from the hidden mathematics that rule the universe to the cosmological principle that guidesStar Trek. The collection begins with a brilliant introduction from Bryson himself, who says: "It is impossible to list all the ways that the Royal Society has influenced the world, but you can get some idea by typing in 'Royal Society' as a word search in the electronic version of theDictionary of National Biography. That produces 218 pages of results — 4,355 entries, nearly as many as for the Church of England (at 4,500) and considerably more than for the House of Commons (3,124) or House of Lords (2,503)." As this book shows, the Royal Society not only produces the best scientists and science, it also produces and inspires the very best science writing.
