Doing Nutrition Differently: Critical Approaches to Diet and Dietary Intervention (Critical Food Studies)
by Jessica Hayes-Conroy Allison Hayes-Conroy'Hegemonic nutrition' is produced and proliferated by a wide variety of social institutions such as mainstream nutrition science, clinical nutrition as well as those less classically linked such as life science/agro-food companies, the media, family, education, religion and the law. The collective result is an approach to and practice of nutrition that alleges not only one single, clear-cut and consented-upon set of rules for 'healthy eating,' but also tacit criteria for determining individual fault, usually some combination of lack of education, motivation, and unwillingness to comply. Offering a collection of critical, interdisciplinary replies and responses to the matter of 'hegemonic nutrition' this book presents contributions from a wide variety of perspectives; nutrition professionals and lay people, academics and activists, adults and youth, indigenous, Chicana/o, Latina/o, Environmentalist, Feminist and more. The critical commentary collectively asks for a different, more attentive, and more holistic practice of nutrition. Most importantly, this volume demonstrates how this 'new' nutrition is actually already being performed in small ways across the American continent. In doing so, the volume empowers diverse knowledges, histories, and practices of nutrition that have been marginalized, re-casts the objectives of dietary intervention, and most broadly, attempts to revolutionize the way that nutrition is done.

Doing Political Ecology
by Gregory L. Simon Kelly KaySince its inception, the field of political ecology has served as a critical hub for inclusive and transformative environmental inquiry. Doing Political Ecology offers a distinctive entry point into this ever-growing field and argues that our scholarly “foundations,” today more than ever, comprise a cross-cutting latticework of research approaches and concepts.This volume brings together 28 leading scholars from a range of backgrounds and geographies, with contributions organized into 18 analytical lenses that highlight different approaches to critical environmental research and “ways of seeing” nature-society interactions. The book's contributors engage the breadth and depth of the field, recognizing a variety of roots and genealogies, and give ample voice to these rich and complementary lineages. This inclusive presentation of the field allows diverse theoretical and empirical approaches to intermingle in novel ways. Readers will emerge with a wide-ranging understanding of political ecology and will attain a diverse toolkit for evaluating human–environment interactions.Each chapter astutely grounds key methodological, theoretical, topical, and conceptual approaches that animate a range of influential, cutting-edge, and complementary ways of “doing” political ecology.

Domain Generalization with Machine Learning in the NOvA Experiment (Springer Theses)
by Andrew T.C. SuttonThis thesis presents significant advances in the use of neural networks to study the properties of neutrinos. Machine learning tools like neural networks (NN) can be used to identify the particle types or determine their energies in detectors such as those used in the NOvA neutrino experiment, which studies changes in a beam of neutrinos as it propagates approximately 800 km through the earth. NOvA relies heavily on simulations of the physics processes and the detector response; these simulations work well, but do not match the real experiment perfectly. Thus, neural networks trained on simulated datasets must include systematic uncertainties that account for possible imperfections in the simulation. This thesis presents the first application in HEP of adversarial domain generalization to a regression neural network. Applying domain generalization to problems with large systematic variations will reduce the impact of uncertainties while avoiding the risk of falsely constraining the phase space. Reducing the impact of systematic uncertainties makes NOvA analysis more robust, and improves the significance of experimental results.
Domains in Ferroic Crystals and Thin Films
by Alexander K Tagantsev L. Eric Cross Jan FousekAt present, the marketplace for professionals, researchers, and graduate students in solid-state physics and materials science lacks a book that presents a comprehensive discussion of ferroelectrics and related materials in a form that is suitable for experimentalists and engineers. This book proposes to present a wide coverage of domain-related issues concerning these materials. This coverage includes selected theoretical topics (which are covered in the existing literature) in addition to a plethora of experimental data which occupies over half of the book. The book presents experimental findings and theoretical understanding of ferroic (non-magnetic) domains developed during the past 60 years. It addresses the situation by looking specifically at bulk crystals and thin films, with a particular focus on recently-developed microelectronic applications and methods for observations of domains with techniques such as scanning force microscopy, polarized light microscopy, scanning optical microscopy, electron microscopy, and surface decorating techniques. "Domains in Ferroic Crystals and Thin Films" covers a large area of material properties and effects connected with static and dynamic properties of domains, which are extremely relevant to materials referred to as ferroics. In other textbooks on solid state physics, one large group of ferroics is customarily covered: those in which magnetic properties play a dominant role. Numerous books are specifically devoted to magnetic ferroics and cover a wide spectrum of magnetic domain phenomena. In contrast, "Domains in Ferroic Crystals and Thin Films" concentrates on domain-related phenomena in nonmagnetic ferroics. These materials are still inadequately represented in solid state physics textbooks and monographs.
Domestic Environmental Labour: An Ecofeminist Perspective on Making Homes Greener (Routledge Explorations in Environmental Studies)
by Carol FarbotkoThis book addresses the question of domestic environmental labour from an ecofeminist perspective. A work of cultural geography, it explores the proposition that the practice and politics of domestic labour being undertaken in the name of ‘the environment’ needs to be better recognized, understood and accounted for as a phenomenon shaped by, and shaping of, gender, class and spatial relations. The book argues that a significant yet neglected phenomenon worthy of research attention is the upsurge in voluntary, and yet mostly unrecognized, domestic environmental labour in high-consuming households in late modernity, with the burden often falling on women seeking to green their lives and homes in aid of a sustainable planet. Further, because domestic environmental labour is undervalued in governance and the formal economy, much like other types of domestic labour, householders have become an unrecognized and unaccounted-for supply of labour for the greening of capitalism. Situated within broad global debates on links between ecological and social change, the book has relevance in the many jurisdictions around the world in which households are positioned as sites of environmental protection through green consumption. The volume engages existing interest in household environmental behaviour and practice, advancing understanding of these topics in new ways.
Domestic Wastewater Treatment in Developing Countries
by Duncan MaraAffordable and effective domestic wastewater treatment is a critical issue in public health and disease prevention around the world, particularly so in developing countries which often lack the financial and technical resources necessary for proper treatment facilities. This practical guide provides state-of-the-art coverage of methods for domestic wastewater treatment and provides a foundation to the practical design of wastewater treatment and re-use systems. The emphasis is on low-cost, low-energy, low-maintenance, high-performance 'natural' systems that contribute to environmental sustainability by producing effluents that can be safely and profitably used in agriculture for crop irrigation and/or in aquaculture, for fish and aquatic vegetable pond fertilization. Modern design methodologies, with worked design examples, are described for waste stabilization ponds, wastewater storage and treatment reservoirs; constructed wetlands, upflow anaerobic sludge blanket reactors, biofilters, aerated lagoons and oxidation ditches. This book is essential reading for engineers, academics and upper-level and graduate students in engineering, wastewater management and public health, and others interested in sustainable and cost-effective technologies for reducing wastewater-related diseases and environmental damage.
Domestic Wild: Memory, Nature and Gardening in Suburbia
by Franklin GinnIn Domestic Wild, Franklin Ginn sets out to find a new sense of the wild at the heart of modernity. Inspired by experienced, skilful gardeners, Ginn analyses what happens when plants, animals and people meet in the suburbs of London. Weaving major theories of landscape, memory and nonhuman subjectivity with the practical wisdom of gardeners, this book offers a radical new account of everyday gardening. Amid spectacular horizons of planetary loss, Domestic Wild argues that gardening offers a means to cultivate a renewed sense of intimacy with nature and ourselves.

Don't Build, Rebuild: The Case for Imaginative Reuse in Architecture
by Aaron BetskyIn a time of climate crisis and housing shortages, a bold, visionary call to replace current wasteful construction practices with an architecture of reuseAs climate change has escalated into a crisis, the reuse of existing structures is the only way to even begin to preserve our wood, sand, silicon, and iron, let alone stop belching carbon monoxide into the air. Our housing crisis means that we need usable buildings now more than ever, but architect and critic Aaron Betsky shows that new construction—often seeking to maximize profits rather than resources, often soulless in its feel—is not the answer. Whenever possible, it is better to repair, recycle, renovate, and reuse—not only from an environmental perspective, but culturally and artistically as well.Architectural reuse is as old as civilization itself. In the streets of Europe, you can find fragments from the Roman Empire. More recently, marginalized communities from New York to Detroit—queer people looking for places to gather or cruise, punks looking to make loud music, artists and displaced people looking for space to work and live—have taken over industrial spaces created then abandoned by capitalism, forging a unique style in the process. Their methods—from urban mining to dumpster diving—now inform architects transforming old structures today.Betsky shows us contemporary imaginative reuse throughout the world: the Mexican housing authority transforming concrete slums into well-serviced apartments; the MassMOCA museum, built out of old textile mills; the squatted city of Christiana in Copenhagen, fashioned from an old army base; Project Heidelberg in Detroit. All point towards a new circular economy of reuse, built from the ashes of the capitalist economy of consumption.
Don't Eat the Cleaners!: Tiny Fish with a Big Job
by Susan StockdaleEven though they live underwater, ocean animals have to get clean, just like we do. But they get it done in a weird and wonderful way.Just like you have to take a bath and brush your teeth, fish also have basic hygiene practices they have to follow every day. But their approach to cleanliness doesn't just take place underwater—it involves a network of larger ocean animals washed by small fish and shrimp called cleaners at coral reef cleaning stations around the world.Cleaners remove pesky parasites from their customers in return for a tasty meal, serving up to 2000 customers a day. Sea turtles, manta rays, and even sharks line up for a scrubbing in the busy stations, just like at a car wash. Some customers return 100 times daily. And they must remember the important rule if they want a washing by the cleaning crew: DON&’T EAT THE CLEANERS!Readers will delight in this colorful exploration of the remarkable teamwork among coral reef residents. Back matter features images of all 30 animals and a fun matching game: can you find the animals in the book?In her latest nonfiction work, award-winning author-illustrator Susan Stockdale once again proves her talent in creating engaging and entertaining nature books for young readers.
Don't Even Think About It: Why Our Brains are Wired to Ignore Climate Change
by George MarshallMost of us recognize that climate change is real, and yet we do nothing to stop it. What is this psychological mechanism that allows us to know something is true but act as if it is not? George Marshall's search for the answers brings him face to face with Nobel Prize-winning psychologists and the activists of the Texas Tea Party; the world's leading climate scientists and the people who denounce them; liberal environmentalists and conservative evangelicals. What he discovered is that our values, assumptions, and prejudices can take on lives of their own, gaining authority as they are shared, dividing people in their wake. <P><P>With engaging stories and drawing on years of his own research, Marshall argues that the answers do not lie in the things that make us different and drive us apart, but rather in what we all share: how our human brains are wired-our evolutionary origins, our perceptions of threats, our cognitive blindspots, our love of storytelling, our fear of death, and our deepest instincts to defend our family and tribe. Once we understand what excites, threatens, and motivates us, we can rethink and reimagine climate change, for it is not an impossible problem. Rather, it is one we can halt if we can make it our common purpose and common ground. Silence and inaction are the most persuasive of narratives, so we need to change the story. <P><P>In the end, Don't Even Think About It is both about climate change and about the qualities that make us human and how we can grow as we deal with the greatest challenge we have ever faced.

Don't Mess With Me: The Strange Lives Of Venomous Sea Creatures (How Nature Works #0)
by Paul Erickson Andrew MartinezThe role of venoms in nature … and in human medicine Why are toxins so advantageous to their possessors as to evolve over and over again? What is it about watery environments that favors so many venomous creatures? Marine biologist Paul Erickson explores these and other questions with astounding images from Andrew Martinez and other top underwater photographers. GREAT for teaching STEM Marine Biology Scorpions and brown recluse spiders are fine as far as they go, but if you want daily contact with venomous creatures, the ocean is the place to be. Blue-ringed octopi, stony corals, sea jellies, stonefish, lionfish, poison-fanged blennies, stingrays, cone snails, blind remipedes, fire urchins—you can choose your poison in the ocean. Venoms are often but not always defensive weapons. The banded sea krait, an aquatic snake, wriggles into undersea caves to prey on vicious moray eels, killing them with one of the world’s most deadly neurotoxins, which it injects through fangs that resemble hypodermic needles.
Don't Tell the Boss!: How Poor Communication on Risks within Organizations Causes Major Catastrophes
by Didier Sornette Dmitry Chernov Ali Ayoub Giovanni SansaviniThe book reviews existing research on the challenges of voice and silence in organizations. After a major disaster, when investigators are piecing together the story of what happened, a striking fact often emerges: before disaster struck, some people in the organization involved were aware of dangerous conditions that had the potential to escalate to a critical level. But for a variety of reasons, this crucial information did not reach decision-makers. So, the organization moved ever closer to catastrophe, effectively unaware of the possible threat—despite the fact that some of its employees could see it coming.What is the problem with communication about risk in an organization, and why does this problem exist? What stops people in organizations or project teams from freely reporting and discussing critical risks? This book seeks to answer these questions, starting from a deep analysis of 20 disasters where the concealment of risks played a major part.These case studies are drawn from around the world and span a range of industries: civil nuclear power, coal, oil and gas production, hydropower energy, metals and mining, space exploration, transport, finance, retail manufacturing and even the response of governments to wars, famines and epidemics.Together, case studies give an insight into why people hesitate to report risks—and even when they do, why their superiors often prefer to ignore the news.This helps to explain more generally why people dread passing on bad news to others—and why in the workplace they prefer to keep quiet about unpleasant facts or potential risks when they are talking to superiors and colleagues.The discussion section of the book includes important examples of concealment within the Chinese state hierarchy as well as by leading epidemiologists and governments in the West during the novel coronavirus outbreak in Wuhan in 2019-2020. The full picture of the very early stage of the COVID-19 pandemic remains unclear, and further research is obviously needed to better understand what motivated some municipal, provincial and national officials in China as well as Western counterparts to obfuscate facts in their internal communications about many issues associated with the outbreak.

Doppler-Effekt und Rotverschiebung: Klassische Theorie und Einsteinsche Effekte (essentials)
by Helmut Günther Volker MüllerDer Doppler-Effekt ist die Frequenzänderung von Wellen bei einer Relativgeschwindigkeit von Sender und Empfänger. So wird die Sirene einer Feuerwehr bei einer Vorbeifahrt deutlich tiefer. Der klassische Doppler-Effekt erlaubt es, den Bewegungszustand des Trägermediums der Wellen zu bestimmen. Für Licht im Vakuum ist die relativistische Gangverzögerung einer bewegten Uhr zu berücksichtigen. Die Frequenzverschiebung hängt dann nur von der Relativgeschwindigkeit ab. Es gibt keinen Bewegungszustand des Vakuums. Der Leser wird in die Lichtausbreitung in Gravitationsfeldern eingeführt. Die Autoren demonstrieren, dass Licht von kompakten Quellen eine gravitative Rotverschiebung erfährt und dass um Schwarze Löcher eine unendliche Rotverschiebung zu beobachten ist. Der Leser erfährt, warum im Kosmos zusätzlich eine kosmologische Rotverschiebung auftritt.
