No one in the Reverend Bell's family wants to leave the beloved old parish behind and move to Crestal New Town, where people haven't had the chance to become friends. The family must work together to engage their new community and bring everyone together.
Equal accessibility to public places and services is now required by law in many countries. In the case of the vision-impaired, it is often the use of specialised technology which can provide them with a fuller enjoyment of all the facilities of society from large scale meetings and public entertainments to the more personal level of reading a book or making music. In this volume the engineering and design principles and techniques used in assistive technology for blind and vision-impaired people are explained. Features:· instruction in the physiology of the human visual system and methods of measuring visual ability;· explanation of many devices designed for every-day living in terms of generic electrical engineering principles;· sections of practical projects and investigations which will give the reader ideas for student work and for self teaching;· contributions by authors of international repute from divers fields which co-operate under the banner of assistive technology, among them: artificial vision systems; psychology, haptics, electrical engineering, design and visual physiology. Assistive Technology for Vision-impaired and Blind People is an an effective means of maintaining the currency of knowledge for engineers and health workers working to provide devices and/or services for people with sight loss and an excellent source of reference for students working in assistive technology and rehabilitation.
[from inside dust jacket flaps:] "It seems like the best of both worlds for Superintendent Robert Bone and his new bride, Grizel: a holiday that combines Bone's passion, a stately houses tour, with a visit to Grizel's friend, Jane, and her husband, Lord Benet Paisley Roke. Roke Castle is on the tour, and, with Roke's penchant for wicked practical jokes--an alligator in the swimming pool, a skeleton in the oubliette--it promises to give full entertainment value. But when an unpopular tour-party guest takes a fatal tumble, and Roke himself is brutally murdered, no one is laughing. For once on the scene of the crime as it happened, Bone---as a potential suspect--has no authority to investigate. He also must endure being grilled by the local Chief Inspector, a working-class boor who seems delighted by a nasty rumor that gives Bone motive as well as opportunity to shove the hapless tourist over the battlements. While the abrasive C.I. continues his interrogations--Lord Roke gave almost everyone, save the butler, ample reason to do him in--Bone joins Roke's two youngest sons in a frantic search for their father's will. Roke's cryptic clues lead everywhere, from the castle's ancient privies, to the library and its collection of rare erotica, to the magnificent gallery filled with Japanese armor. For the boys, the treasure hunt is a welcome distraction. But the press is camped on the doorstep, and the beleaguered adults can only wonder whether Roke would have skipped this last prank if he'd known he was going to be murdered. For Grizel and Bone, who must snatch their tender moments amidst the chaos, it is an odd honeymoon: a foretaste of their future life together. As Grizel helps Jane cope with the duties of a bereaved widow, Bone cannot resist carrying out a few discreet inquiries. And, in the explosive aftermath of the reading of the will, Bone--in a flash of sudden, blinding clarity--must spring into action, racing to stop a bold and reckless killer who is poised to strike again."

This book is about honesty. Honesty may be a bit over the heads of young children since, in some cases, they are not developmentally able to see it the same as adults. In addition, they are at a level when their goal is to please and not lose the affection of the important adults in their lives. Often, when faced with a question requiring the truth, they may feel conflicted and want to escape the situation by giving a fanciful excuse. Try This: One way to use this book is to set up .situations that would require honest answers, and ask, "What would you do?" Then ask, "Why do you think this is a good choice?"

Through biographies of China's most colorful and famous personalities, John Wills displays the five-thousand-year sweep of Chinese history from the legendary sage emperors to the tragedy of Tiananmen Square. This unique introduction to Chinese history and culture uses more than twenty exemplary lives--biographies of China's most colorful and famous personalities--including those of statesmen, philosophers, poets, and rulers, to provide the focus for accounts of key historical trends and periods. What emerges is a provocative rendering of China's moral landscape, featuring characters who have resonated in the historical imagination as examples of villainy, heroism, wisdom, spiritual vision, political guile, and complex combinations of all of these.Investigating both the legends and the facts surrounding these figures, Wills reveals the intense interest of the Chinese in the brilliance and in the frail complexities of their heroes. Included, for instance, is a description of the frustrations and anxieties of Confucius, who emerges as a vulnerable human being trying to restore the world to the virtue and order of the sage kings. Wills recounts and questions the wonderfully shocking stories about the seventh-century Empress Wu, an astute ruler and shaper of an increasingly centralized monarchy, who has since assumed a prominent position in the Chinese tradition's rich gallery of bad examples--because she was a woman meddling in politics. The portrayal of Mao Zedong, which touches upon this leader's earthy personality and his reckless political visions, demonstrates the tendency of the Chinese not to divorce ideology from its human context: Maoism for them is a form of "objective" Marxism, inseparable from one man's life and leadership. Each of the twenty chapters provides a many-sided exploration of a "slice" of Chinese history, engaging the general reader in a deep and personal encounter with China over the centuries and today. The biographies repeatedly mirror the moral earnestness of the Chinese, the great value they place on the ruler-minister relationship, and their struggles with tensions among practicality, moral idealism, and personal authenticity. Culminating in a reflection on China's historical direction in the aftermath of Tiananmen Square, the biographies show the modern Chinese still inspired and frustrated by a complex heritage of moral fervor and political habits and preconceptions. As absorbing as it is wide ranging, this history is written for the general public curious about China and for the student beginning to study its rich cultural heritage.This new edition highlights important figures that have emerged in China since the book's initial publication and provides updated suggestions for further reading.
Can a country be a democracy if its government only responds to the preferences of the rich? In an ideal democracy, all citizens should have equal influence on government policy--but as this book demonstrates, America's policymakers respond almost exclusively to the preferences of the economically advantaged. Affluence and Influence definitively explores how political inequality in the United States has evolved over the last several decades and how this growing disparity has been shaped by interest groups, parties, and elections. With sharp analysis and an impressive range of data, Martin Gilens looks at thousands of proposed policy changes, and the degree of support for each among poor, middle-class, and affluent Americans. His findings are staggering: when preferences of low- or middle-income Americans diverge from those of the affluent, there is virtually no relationship between policy outcomes and the desires of less advantaged groups. In contrast, affluent Americans' preferences exhibit a substantial relationship with policy outcomes whether their preferences are shared by lower-income groups or not. Gilens shows that representational inequality is spread widely across different policy domains and time periods. Yet Gilens also shows that under specific circumstances the preferences of the middle class and, to a lesser extent, the poor, do seem to matter. In particular, impending elections--especially presidential elections--and an even partisan division in Congress mitigate representational inequality and boost responsiveness to the preferences of the broader public. At a time when economic and political inequality in the United States only continues to rise, Affluence and Influence raises important questions about whether American democracy is truly responding to the needs of all its citizens.
What are your chances of dying on your next flight, being called for jury duty, or winning the lottery? We all encounter probability problems in our everyday lives. In this collection of twenty-one puzzles, Paul Nahin challenges us to think creatively about the laws of probability as they apply in playful, sometimes deceptive, ways to a fascinating array of speculative situations. Games of Russian roulette, problems involving the accumulation of insects on flypaper, and strategies for determining the odds of the underdog winning the World Series all reveal intriguing dimensions to the workings of probability. Over the years, Nahin, a veteran writer and teacher of the subject, has collected these and other favorite puzzles designed to instruct and entertain math enthusiasts of all backgrounds. If idiots A and B alternately take aim at each other with a six-shot revolver containing one bullet, what is the probability idiot A will win? What are the chances it will snow on your birthday in any given year? How can researchers use coin flipping and the laws of probability to obtain honest answers to embarrassing survey questions? The solutions are presented here in detail, and many contain a profound element of surprise. And some puzzles are beautiful illustrations of basic mathematical concepts: "The Blind Spider and the Fly," for example, is a clever variation of a "random walk" problem, and "Duelling Idiots" and "The Underdog and the World Series" are straightforward introductions to binomial distributions. Written in an informal way and containing a plethora of interesting historical material, Duelling Idiots is ideal for those who are fascinated by mathematics and the role it plays in everyday life and in our imaginations.
Have you ever daydreamed about digging a hole to the other side of the world? Robert Banks not only entertains such ideas but, better yet, he supplies the mathematical know-how to turn fantasies into problem-solving adventures. In this sequel to the popular Towing Icebergs, Falling Dominoes (Princeton, 1998), Banks presents another collection of puzzles for readers interested in sharpening their thinking and mathematical skills. The problems range from the wondrous to the eminently practical. In one chapter, the author helps us determine the total number of people who have lived on earth; in another, he shows how an understanding of mathematical curves can help a thrifty lover, armed with construction paper and scissors, keep expenses down on Valentine's Day.In twenty-six chapters, Banks chooses topics that are fairly easy to analyze using relatively simple mathematics. The phenomena he describes are ones that we encounter in our daily lives or can visualize without much trouble. For example, how do you get the most pizza slices with the least number of cuts? To go from point A to point B in a downpour of rain, should you walk slowly, jog moderately, or run as fast as possible to get least wet? What is the length of the seam on a baseball? If all the ice in the world melted, what would happen to Florida, the Mississippi River, and Niagara Falls? Why do snowflakes have six sides?Covering a broad range of fields, from geography and environmental studies to map- and flag-making, Banks uses basic algebra and geometry to solve problems. If famous scientists have also pondered these questions, the author shares the historical details with the reader. Designed to entertain and to stimulate thinking, this book can be read for sheer personal enjoyment.
As human populations grow and resources are depleted, agriculture will need to use land, water, and other resources more efficiently and without sacrificing long-term sustainability. Darwinian Agriculture presents an entirely new approach to these challenges, one that draws on the principles of evolution and natural selection. R. Ford Denison shows how both biotechnology and traditional plant breeding can use Darwinian insights to identify promising routes for crop genetic improvement and avoid costly dead ends. Denison explains why plant traits that have been genetically optimized by individual selection--such as photosynthesis and drought tolerance--are bad candidates for genetic improvement. Traits like plant height and leaf angle, which determine the collective performance of plant communities, offer more room for improvement. Agriculturalists can also benefit from more sophisticated comparisons among natural communities and from the study of wild species in the landscapes where they evolved. Darwinian Agriculture reveals why it is sometimes better to slow or even reverse evolutionary trends when they are inconsistent with our present goals, and how we can glean new ideas from natural selection's marvelous innovations in wild species.
Nutrition has long been considered more the domain of medicine and agriculture than of the biological sciences, yet it touches and shapes all aspects of the natural world. The need for nutrients determines whether wild animals thrive, how populations evolve and decline, and how ecological communities are structured. The Nature of Nutrition is the first book to address nutrition's enormously complex role in biology, both at the level of individual organisms and in their broader ecological interactions. Stephen Simpson and David Raubenheimer provide a comprehensive theoretical approach to the analysis of nutrition--the Geometric Framework. They show how it can help us to understand the links between nutrition and the biology of individual animals, including the physiological mechanisms that determine the nutritional interactions of the animal with its environment, and the consequences of these interactions in terms of health, immune responses, and lifespan. Simpson and Raubenheimer explain how these effects translate into the collective behavior of groups and societies, and in turn influence food webs and the structure of ecosystems. Then they demonstrate how the Geometric Framework can be used to tackle issues in applied nutrition, such as the problem of optimizing diets for livestock and endangered species, and how it can also help to address the epidemic of human obesity and metabolic disease Drawing on a wealth of examples from slime molds to humans, The Nature of Nutrition has important applications in ecology, evolution, and physiology, and offers promising solutions for human health, conservation, and agriculture.
This is a thoroughly revised, updated, and expanded edition of a classic illustrated introduction to the structural materials in natural organisms and what we can learn from them to improve man-made technolog---from nanotechnology to textiles to architecture. Julian Vincent's book has long been recognized as a standard work on the engineering design of biomaterials and is used by undergraduates, graduates, researchers, and professionals studying biology, zoology, engineering, and biologically inspired design. This third edition incorporates new developments in the field, the most important of which have been at the molecular level. All of the illustrations have been redrawn, the references have been updated, and a new chapter on biomimetic design has been added. Vincent emphasizes the mechanical properties of structural biomaterials, their contribution to the lives of organisms, and how these materials differ from man-made ones. He shows how the properties of biomaterials are derived from their chemistry and interactions, and how to measure them. Starting with proteins and polysaccharides, he shows how skin and hair function, how materials self-assemble, and how ceramics such as bone and mother-of-pearl can be so stiff and tough, despite being made in water in benign ambient conditions. Finally, he combines these topics with an analysis of how the design of biomaterials can be adapted in technology, and presents a series of guidelines for designers.An accessible illustrated introduction with minimal technical jargon Suitable for undergraduates and more advanced readers Integrates chemistry, mechanics, and biology Includes descriptions of all biological materials Simple exposition of mechanical analysis of materials
