Contrast-enhanced breast MRI is a highly sensitive modality for early detection and diagnosis of breast cancer, particularly in high-risk populations. It has also been shown to be superior to mammography in establishing the extent of disease in patients with newly diagnosed breast cancer. This chapter, appearing in the section on breast cancer overview, reviews breast MRI imaging technique, clinical uses, gives an overview of image interpretation, and applied physics. Topics discussed include equipment such as hardware, imaging protocols, patient preparation and positioning, and relevant physics. Additionally, clinical situations where the use of breast MRI is appropriate, systematic review of images, and formulation of final assessment and recommendations in accordance with the ACR BI-RADS imaging lexicon are discussed in this chapter.

Americans love talk shows. In a typical week, more than 13 million Americans listen to Rush Limbaugh, whose syndicated radio show is carried by about 600 stations. On television, Oprah Winfrey's syndicated talk show is seen by an estimated 30 million viewers each week. Talk show hosts like Winfrey and Limbaugh have become iconic figures, frequently quoted and capable of inspiring intense opinions. What they say on the air is discussed around the water cooler at work, or commented about on blogs and fan web sites. Talk show hosts have helped to make or break political candidates, and their larger-than-life personalities have earned them millions of fans (as well as more than a few enemies). Icons of Talk highlights the most groundbreaking exemplars of the talk show genre, a genre that has had a profound influence on American life for over 70 years. Among the featured: • Joe Pyne • Jerry Williams • Herb Jepko • Randi Rhodes • Rush Limbaugh • Larry King • Dr. Laura Schlesinger • Steve Allen • Jerry Springer • Howard Stern. • Oprah Winfrey • Don Francisco • Cristina Saralegui • Tavis Smiley • James Dobson • Don Imus Going behind the scenes, this volume showcases the techniques hosts used to motivate (and sometimes aggravate) audiences, and examines the talk show in all of its various formats, including sports-talk, religious-talk, political-talk, and celebrity-talk. Each entry places the talk format and its hosts into historical context, addressing such questions as: What was going on in society when these talkers were on the air? How did each of them affect or change society? What were the issues they liked to talk about and what reaction did they get from listeners and from critics? How were talk hosts able to persuade people to vote for particular candidates or support certain policies? Which hosts were considered controversial and why? Complete with photographs, a timeline, and a resource guide of sources and organizations, this volume is ideal for students of journalism and media studies.

Administrative Law explains the constitutional principles of the subject. It brings clarity to this complex field of public law. The common law courts, government agencies, and Parliament have developed a wide variety of techniques for controlling the enormously diverse activities of twenty-first-century government. Underlying all that variety is a set of constitutional principles. This book uses the law of judicial review to identify and to explain these principles, and then shows how they ought to be worked out in the private law of tort and contract, in the tribunals system, and in non-judicial techniques such as investigations by ombudsmen, auditors, and other government agencies. The aim is to equip the reader to take a principled approach to the controversial problems of administrative law.

This book examines the practical techniques humanitarians have used to manage and measure starvation, from Victorian “scientific” soup kitchens to space-age, high-protein foods. Tracing the evolution of these techniques since the start of the nineteenth century, the book argues that humanitarianism is not a simple story of progress and improvement, but rather is profoundly shaped by sociopolitical conditions. Aid is often presented as an apolitical and technical project, but the way humanitarians conceive and tackle human needs has always been deeply influenced by culture, politics, and society. These influences extend down to the most detailed mechanisms for measuring malnutrition and providing sustenance. As the book shows, over the past century, the humanitarian approach to hunger has redefined food as nutrients and hunger as a medical condition. Aid has become more individualized, medicalized, and rationalized, shaped by modernism in bureaucracy, commerce, and food technology. The book focuses on the gains and losses that result, examining the complex compromises that arise between efficiency of distribution and quality of care. It concludes that humanitarian groups have developed an approach to the empty stomach that is dependent on compact, commercially produced devices and is often paternalistic and culturally insensitive.

Administrative Law explains the constitutional principles of the subject and their application across the range of twenty-first-century administrative law. The focus on constitutional principles is meant to bring some order to the very diverse topics with which you need to deal if you are to understand this very complex branch of public law. The common law courts, government agencies, and Parliament have developed a wide variety of techniques for controlling the enormously diverse activities of twenty-first-century government. Underlying all that variety is a set of constitutional principles. This book uses the law of judicial review to identify and to explain these principles, and then shows how they ought to be worked out in the private law of tort and contract, in the tribunals system, and in non-judicial techniques such as investigations by ombudsmen, auditors, and other government agencies. The aim is to equip the reader to take a principled approach to the controversial problems of administrative law.

Australian Forest Woods describes about 130 of the most significant Australian forest trees and their wood. The introductory sections introduce the reader to the uniqueness and usefulness of forest trees. The book examines the forest tree species and their wood with photographs, botanical descriptions and a summary of the characteristics of the wood. A section on wood identification includes fundamental information on tree growth and wood structure. With over 900 images, this is the most comprehensive guide ever written on Australian forest woods, both for the amateur and the professional wood enthusiast. Macrophotographs of the wood are shown in association with a physical description of wood characteristics, which will aid identification. This technique was developed by Jean-Claude Cerre, France, and his macrophotographs are included in the book.

Global smallpox eradication was achieved only after decades of unsuccessful experiments in smallpox-endemic countries. A case in point occurred in 1958 when a severe epidemic imposed heavy mortality on East Pakistan. In response a Bengali regional-nationalist ‘Citizens Provincial Epidemic Control Committee’ pushed aside the provincial health department and launched an eradication campaign based on student volunteers using foreign-donated vaccine. In a period of ten weeks thousands of volunteers vaccinated thirty million Bengalis, albeit relying on shortcuts in sterile technique and neglect of patient record-keeping. The US government, in support of its Cold War ally, Pakistan, provided half of the vaccine supplies. The US also sent a team of Communicable Disease Center epidemiologists to assist public health officials. The team, led by Alexander D. Langmuir, proposed ‘active surveillance’ methods but was constrained by T. Aidan Cockburn, the Chief Public Health Adviser, who favored the Bengalis’ volunteer approach. A struggle developed between politicised volunteerism and epidemiological professionalism, and the CDC experts failed to prevail. The two sides' published reports thus made contradictory recommendations to the global campaign, but subsequent experience has shown that both mass participation and active surveillance are critical ingredients for successful disease control and eradication programmes.

The opening decades of the twentieth century witnessed a profound transformation in the history of modern sound media, with workers in US film, radio, and record industries developing pioneering production methods and performance styles tailored to emerging technologies of electric sound reproduction that directly shaped dominant forms and experiences of modern sound culture. Focusing on broadcasting’s initial expansion period during the 1920s, Making Radio explores the forms of creative labor pursued for the medium before the better-known network era of the 1930s and 1940s, assessing their role in shaping radio’s own identity and identifying affinities with parallel practices pursued for conversion-era film and phonography. Tracing programming forms adopted by early radio writers and programmers, production techniques developed by studio engineers, and performance styles cultivated by on-air talent, it shows how radio workers negotiated a series of broader industrial and cultural pressures to establish best practices for their medium. In the process, it argues, these sound workers shaped not only the future of broadcasting, but also contributed to much broader shifts in popular forms of music, drama, and public oratory, ushering in a new era of electric sound entertainment.

Australian Rainforest Woods describes 141 of the most significant Australian rainforest trees and their wood. The introductory sections draw the reader into an understanding of the botanical, evolutionary, environmental, historical and international significance of this beautiful but finite Australian resource. The main section examines the species and their wood with photographs, botanical descriptions and a summary of the characteristics of the wood. A section on wood identification includes fundamental information on tree growth and wood structure, as well as images of the basic characteristics. With more than 900 colour images, this is the most comprehensive guide ever written on Australian rainforest woods, both for the amateur and the professional wood enthusiast. It is the first time that macrophotographs of the wood have been shown in association with a physical description of wood characteristics, which will aid identification. This technique was developed by Jean-Claude Cerre, France, and his macrophotographs are included in the book.

Despite social and economic advances around the world, poverty and disease persist, exacerbated by the mounting challenges of climate change, natural disasters, political conflict, mass migration, and economic inequality. While governments commit to addressing these challenges, traditional public and philanthropic dollars are not enough. Here, innovative finance has shown a way forward: by borrowing techniques from the world of finance, we can raise capital for social investments today. Innovative finance has provided polio vaccines to children in the DRC, crop insurance to farmers in India, pay-as-you-go solar electricity to Kenyans, and affordable housing and transportation to New Yorkers. It has helped governmental, commercial, and philanthropic resources meet the needs of the poor and underserved and build a more sustainable and inclusive prosperity. Capital and the Common Good shows how market failure in one context can be solved with market solutions from another: an expert in securitization bundles future development aid into bonds to pay for vaccines today; an entrepreneur turns a mobile phone into an array of financial services for the unbanked; and policy makers adapt pay-for-success models from the world of infrastructure to human services like early childhood education, maternal health, and job training. Revisiting the successes and missteps of these efforts, Georgia Levenson Keohane argues that innovative finance is as much about incentives and sound decision-making as it is about money. When it works, innovative finance gives us the tools, motivation, and security to invest in our shared future.

We are living through a revolution in our ability to study Early Modern literature and culture: EEBO‒TCP offers the possibility of searching something close to the entire corpus of surviving Early Modern printed books. Such access enables us to consider questions involving larger numbers of documents than have hitherto been the norm. However, investigating at scale requires different approaches to scholarship: it is not practical to close-read tens of thousands of texts. To make the most of these new resources, we must integrate traditional literary scholarship with new approaches. This chapter gives an example of such a combined approach. We consider the language of 554 printed plays from the Early Modern period. We explore two research questions: (a) is there a distinct ‘language of tragedy’? (b) is there a distinctively Shakespearean language of tragedy? We aim to show how computational and traditional literary techniques can be combined to answer these questions.

World-renowned contributors across several disciplines reveal how dreams can aid and empower children in daily life. Children can feel powerless in waking life, a fact that is often reflected in their dreams. This book shows how to take an active role in guiding children’s dreams to help grow their confidence and improve their coping skills for real-life difficulties. Contributors from across various fields provide simple techniques to help children utilize dreamwork as a conduit for creative discovery and empowerment. Each chapter includes case studies and methods for working in practical ways with children, explaining what may trigger nightmares for children and how “monster” dreams can be guided to become “superhero” dreams. Essays encompass a spectrum of children’s dreams with experts discussing dreams of trauma, dreams as a reflection of emotional and physical development, dreaming in the community, spiritual or religious dreams, lucid dreams, dreams during wartime, and dreams of death, among others. Throughout the work, the narrative discusses the use of dreams as teaching aids for use in art therapy, storytelling, and self-empowerment.

The aim of this manual is to improve the welfare of dairy cattle in tropical developing countries, and by doing so, optimise cow and herd performance. It gives the stockmen and farmers directly concerned with the cattle a better understanding of animal behaviour and the ways cattle communicate their comfort or distress. The book discusses normal cattle behaviour and shows how domestication and breeding can affect behaviour to achieve high levels of production of milk, live weight gain and fertility. Animal welfare is important for producers because it can affect the health, production and contentment of cows. Animal welfare practices which adversely affect cow and herd performance on tropical small holder dairy farms are identified. Advice is then given to change the animal's environment or modify a handler's technique to ensure cattle have the degree of comfort needed to achieve more profitable and sustainable systems of livestock farming. Cow Talk will be a beneficial resource for farmers who want to improve animal welfare, farm advisers who can assist farmers to improve their welfare practices, educators who develop training programs for farmers and dairy advisers, and other stakeholders in tropical dairy production such as local agribusiness, policy makers and research scientists.

This book is about the different philosophical paradigms and ideas that influence qualitative research. Its aim is to discuss and evaluate the ways that philosophical positions inform qualitative research as currently practiced. Unlike other contributions to the field, this book takes a historical perspective and shows how the philosophical ideas have evolved and influenced qualitative research in previous times and today. Today, qualitative researchers often report on their philosophical commitments (if they do so at all) in a separate section of their papers, but this book is written from the perspective that philosophical ideas influence everything in the research process from the first formulation of a research theme to the final reporting of the results. Therefore, it is preferable to highlight how this happens. Philosophy should thus not be thought of as a purely abstract discipline, disconnected from the practicalities of research, but rather as a concrete and pervasive aspect of all qualitative research practices. This book does not provide in-depth treatments of qualitative methods and techniques such as interviewing, document analysis, or participant observation, but rather aims to introduce and discuss the philosophical issues that are relevant regardless of the specific methods employed by qualitative researchers.

Despite being the product of Roger Corman's AIP exploitation studio, House of Usher enjoys a high standing. But while the impact and cult status of Corman's Edgar Allan Poe cycle is often discussed in histories of gothic, horror, and exploitation cinema, no extended analysis and critical discussion has been published to date that explores specifically the aesthetic appeal of House of Usher. This book provides a complete study of the aesthetic appeal of Corman's influential first Poe picture. The book explores the underlying narrative structure borrowed from Poe's original story and shows how closely Richard Matheson's script followed Poe's theory of short fiction. It goes on to explore the formal techniques of allegory and symbolism employed to represent the house as a monster before focusing on Corman's imagery, showing how the use of specific camera angles, lenses, colors, and sound effects create and sustain the simultaneously morbid and beautiful atmosphere of gothic decay. Finally, the book situates horror icon Vincent Price's performance as Roderick Usher in the context of the nineteenth-century Romantic misfit and the postwar countercultural antihero, two closely related cultural identities.

This book sets out to show how new markets were cultivated by printers in the period 1476–1550. It argues that while print and manuscript reading continued alongside each other, developments in the marketing of printed texts began to change what readers read, the ways they read and the place of reading in their lives on a larger scale and at a faster pace than had occurred before. Rather than attempting to offer a superficial survey of how the marketing of every kind of book developed, it focuses on three broad (but not wholly discreet) categories: religious reading, secular reading, and practical reading. Within those categories, the chapters focus in detail on the development of types of book that either emerged for the first time during this period (evangelical books, news pamphlets) or underwent considerable changes in presentation (devotional texts, romances, travel guides, household works). The chapters examine the presentation of early printed editions, paying particular attention to paratexts, with the aim of illuminating the range of techniques that printers used to convince potential buyers to part with their money. The printers of these works were predominantly based in London, but this book places their efforts within a wider European context. It demonstrates that, just as English manuscripts were moulded by foreign influences, English printers responded to their European counterparts’ experiments in the marketing of books.

While many think of algorithms as specific to computer science, at its core algorithmic thinking is defined by the use of analytical logic to solve problems. This logic extends far beyond the realm of computer science and into the wide and entertaining world of puzzles. In Algorithmic Puzzles, Anany and Maria Levitin use many classic brainteasers as well as newer examples from job interviews with major corporations to show readers how to apply analytical thinking to solve puzzles requiring well-defined procedures. The book's unique collection of puzzles is supplemented with carefully developed tutorials on algorithm design strategies and analysis techniques intended to walk the reader step-by-step through the various approaches to algorithmic problem solving. Mastery of these strategies--exhaustive search, backtracking, and divide-and-conquer, among others--will aid the reader in solving not only the puzzles contained in this book, but also others encountered in interviews, puzzle collections, and throughout everyday life. Each of the 150 puzzles contains hints and solutions, along with commentary on the puzzle's origins and solution methods. The only book of its kind, Algorithmic Puzzles houses puzzles for all skill levels. Readers with only middle school mathematics will develop their algorithmic problem-solving skills through puzzles at the elementary level, while seasoned puzzle solvers will enjoy the challenge of thinking through more difficult puzzles.

A stunning book on kintsugi, the Japanese art of repairing broken pottery with precious metals to highlight its history beautifully. A broken pot is made whole again, and within its golden repair we see a world of meaning. Kintsugi is the art of embracing imperfection. In Western cultures, the aim of repair has been to make the broken item ‘as good as new’. Kintsugi on the other hand, is a Japanese art that leaves an obvious repair – one that may appear fragile, but which actually makes the restored ceramic piece stronger, more beautiful, and more valuable than before. Leaving clear, bold, visible lines with the appearance of solid gold, it never hides the story of the object’s damage. Kintsugi traces memory, bringing together the moment of destruction and the gold seams of repair through finely-honed skills and painstaking, time-consuming labour in the creation of a new pot from the old. There is a story to be told with every crack, every chip. This story inevitably leads to kintsugi’s greatest strength. an intimate metaphoric narrative of loss and recovery, breakage and restoration, tragedy and the ability to overcome it. A kintsugi repair speaks of individuality and uniqueness, fortitude and resilience, and the beauty to be found in survival. Kintsugi leads us to a respectful and appreciative acceptance of hardship and ageing. Author Bonnie Kemske explores kintsugi's metaphorical power as well as exploring the technical and practical aspects of the art, meeting with artists and ceramists in Japan and the US to discuss their personal connection to this intricate technique. With the inclusion of diary entries, personal stories, and in-depth exploration of its origin and symbolism, this book shows kintsugi's metaphoric strength as well as its striking aesthetic, making it a unique and powerful art form that can touch our lives.

This book presents a theory of enriched meanings for natural language interpretation. Certain expressions that exhibit complex effects at the semantics/pragmatics boundary live in an enriched meaning space while others live in a more basic meaning space. These basic meanings are mapped to enriched meanings just when required compositionally, which avoids generalizing meanings to the worst case. The theory is captured formally using monads, a concept from category theory. Monads are also prominent in functional programming and have been successfully used in the semantics of programming languages to characterize certain classes of computation. They are used here to model certain challenging linguistic computations at the semantics/pragmatics boundary. Part I presents some background on the semantics/pragmatics boundary, informally presents the theory of enriched meanings, reviews the linguistic phenomena of interest, and provides the necessary background on category theory and monads. Part II provides novel compositional analyses of the following phenomena: conventional implicature, substitution puzzles, and conjunction fallacies. Part III explores the prospects of combining monads, with particular reference to these three cases. The authors show that the compositional properties of monads model linguistic intuitions about these cases particularly well. The book is an interdisciplinary contribution to Cognitive Science: These phenomena cross not just the boundary between semantics and pragmatics, but also disciplinary boundaries between Linguistics, Philosophy and Psychology, three of the major branches of Cognitive Science, and are here analyzed with techniques that are prominent in Computer Science, a fourth major branch. A number of exercises are provided to aid understanding, as well as a set of computational tools (available at the book's website), which also allow readers to develop their own analyses of enriched meanings.

The aim of the study was to determine the influence of different disturbances (both natural and anthropogenic) on species composition and stand structure of old-growth mixed mountain forests in the Western Carpathians. These stands are usually dominated by beech, fir and spruce, mixed in different proportions. The tree main species represent different growth strategies, and they compete against each other. The longevity of trees makes the factors influencing the stand structure difficult to identify, even during longitudinal studies conducted on permanent research plots. That is why dendroecological techniques, based upon the annual variability of tree rings, are commonly used to analyze the disturbance histories of old-growth stands. Dendroecological methods make it possible to reconstruct the stand history over several centuries in the past by analyzing the frequency, intensity, duration and spatial scale of disturbances causing the death of trees. Combining the dendroecological techniques with the detailed measurements of stand structure, snag volume, CWD volume, and the analyses of regeneration species composition and structure allows us to identify the factors responsible for the changes in dynamics of mixed mountain forests. Various disturbance agents affect some species selectively, while some disturbances promote the establishment of tree seedlings of specific species by modifying environmental conditions. Describing the disturbance regime requires a broad scope of data on stand structure, on dead wood and tree regeneration, while various factors affecting all the stages of tree growth should be taken into consideration. On the basis of the already published data from permanent sample plots, combined with the available disturbance history analyses from the Western Carpathians, three research hypotheses were formulated. 1. The species composition of mixed mountain forests has been changing for at least several decades. These directional changes are the consequence of simultaneous conifer species decline and expansion of beech. 2. The observed changes in species composition of mixed mountain forests are the effect of indirect anthropogenic influences, significantly changing tree growth conditions also in the forests that are usually considered natural or near-natural. Cumulative impact of these indirect influences leads to the decrease of fir share in the tree layer (spruce decline has also been observed recently),and it limits the representation of this species among seedlings and saplings. The final effect is the decrease of fir and spruce share in the forest stands. 3. Small disturbances, killing single trees or small groups of trees, and infrequent disturbances of medium size and intensity dominate the disturbance regime in mixed mountain forests. The present structure of beech-fir-spruce forests is shaped both by complex disturbance regime and indirect anthropogenic influences. The data were gathered in permanent sample plots in strictly protected areas of Babia Góra, Gorce, and Tatra National Parks, situated in the Western Carpathians. All plots were located in the old-growth forest stands representing Carpathian beech forest community. The results of the measurements of trees, snags, coarse woody debris (CWD) and tree regeneration were used for detailed description of changes in the species composition and structure of tree stands. Tree ring widths derived from increment cores were used to reconstruct the historical changes in tree growth trends of all main tree species, as well as the stand disturbance history within the past two to three hundred years. The analyses revealed complex disturbance history in all of the three forest stands. Intermediate disturbances of variable intensity occurred, frequently separated by the periods of low tree mortality lasting from several decades up to over one hundred years. The intervals between the disturbances were significantly shorter than the expected length of forest developmental cycle, in commonly used theories describing the dynamics of old-growth stands. During intermediate disturbances up to several dozen percent of canopy trees were killed. There were no signs of stand-replacing disturbances, killing all or nearly all of canopy trees. The periods of intense tree mortality were followed by subsequent periods of increased sapling recruitment. Variability in disturbance intensity is one of the mechanisms promoting the coexistence of beech and conifer species in mixed forests. The recruitment of conifer saplings depended on the presence of larger gaps, resulting from intermediate disturbances, while beech was more successful in the periods of low mortality. However, in the last few decades, beech seems to benefit from the period of intense fir mortality. This change results from the influence of long-term anthropogenic disturbances, affecting natural mechanisms that maintain the coexistence of different tree species and change natural disturbance regimes. Indirect anthropogenic influence on tree growth was clearly visible in the gradual decrease of fir increments in the twentieth century, resulting from the high level of air pollution in Europe. Synchronous decreases of fir tree rings’ widths were observed in all three of the sample plots, but the final outcomes depended on the fir age. In most cases, the damage to the foliage limited the competitive abilities of fir, but it did not cause a widespread increase in tree mortality, except for the oldest firs in the BGNP (Babia Góra National Park) plot. BGNP is located in the proximity of industrial agglomeration of Upper Silesia, and it could be exposed to higher level of air pollution than the other two plots. High level of fir regeneration browsing due to the deer overabundance and insufficient number of predators is the second clear indication of the indirect anthropogenic influence on mixed mountain forests. Game impact on fir regeneration is the most pronounced in Babia Góra forests, where fir was almost completely eliminated from the saplings. Deer browsing seems to be the main factor responsible for limiting the number of fir saplings and young fir trees, while the representation of fir among seedlings is high. The experiments conducted in fenced plots located in the mixed forests in BGNP proved that fir and sycamore were the most preferred by deer species among seedlings and saplings. In GNP (Gorce National Park) and TNP (Tatra National Park), the changes in species composition of tree regeneration are similar, but single firs or even small groups of firs are present among saplings. It seems that all of the analysed mixed beech-fir-spruce forests undergo directional changes, causing a systematic decrease in fir representation, and the expansion of beech. This tendency results from the indirect anthropogenic impact, past and present. Fir regeneration decline, alongside with the high level of spruce trees’ mortality in recent years, may lead to a significant decrease in conifers representation in the near future, and to the expansion of beech forests at the cost of mixed ones.
