Welding Technical Communication: Teaching and Learning Embodied Knowledge (SUNY series, Studies in Technical Communication)
by Jo MackiewiczWelding Technical Communication explores the teaching and learning of welding through two narratives. The personal narrative relates the author’s experience as a woman learning how to weld. The academic narrative draws upon scaffolded learning theory to examine how four welding teachers’ verbal and nonverbal communication—their tutoring strategies and their gestures—facilitated students’ embodied knowledge and enculturation into a community of practice. This book fills a gap in technical communication research: we do not fully understand how teachers’ pedagogical technical communication scaffolds students’ learning within the skilled trades. Novel in its approach and coverage, Welding Technical Communication will interest researchers in technical communication and technical education.

The Welfare of Cattle
by Bernard E. Rollin Terry Engle Donald J. Klingborg, DVMContains a selection of White Papers, commissioned to better inform the exploration of cattle welfare. These are prepared by notable experts in their field, to help provide factual context around selected topics that impact cattle welfare and production systems. Covers all aspects of cattle use in an accessible style, making this a must have volume for anyone interested in cattle welfare or cattle medicine. Provides an in-depth picture of the distinctive beef and dairy cattle welfare practices and issues, covering topics such as behavior, breeding and genetic manipulation, nutrition and feeding, housing and management, health and disease, and transport and slaughter. Written by acknowledged leaders in animal science, veterinary science, philosophy and animal welfare, presenting a truly multidisciplinary perspective on cattle welfare. Includes a section on understanding and managing animal welfare in both beef and dairy cattle, discussing how cattle perceive the world, animal handling and pain mitigation, and how to assure that the cows have a reasonably good life. The Welfare of Cattle offers an accurate, detailed account of the ethical and welfare concerns related to the human use of cattle. There is currently no significant book dealing with the welfare of cows, animals often seen as archetypal paradigms of 'farm animals'. Covering both beef and dairy cattle, the expert authors provide in-depth information on the husbandry roots of traditional agriculture, the replacement of this system of stewardship by an industrial model, and the resulting welfare challenges associated with industrial agriculture: feedlots, highly industrialized dairies, and slaughterhouses killing huge numbers of animals who have been transported great distances. This important book explores in detail the ways in which people who are providing care for cattle can take their first step, or their next step, toward enhancing the welfare of these animals. An extra chapter (online only) is available in the 'Downloads' tab on the left: Dairy Nutrition, by Michael Gamroth
The Welfare of Farmed Ratites
by Irek Malecki Christine Lunam Phil GlatzThis volume reviews, for the first time, the broad range of issues that affect the welfare of commercially farmed ratites. Although ratites incorporate several families of flightless birds this book focuses on the most commonly farmed ratites, the ostrich, emu and rhea. The readers are taken on a journey through all sectors of the industry, which include breeding, incubation, hatching, brooding, rearing, growth, transport and processing, with an emphasis on husbandry and management protocols that can impact bird welfare and health. Also discussed is the structure and sensory innervation of the skin and digits of the birds, and the potential welfare implications of industry practices on these structures. Each chapter in this volume focuses on a particular aspect of the commercial farming of ratites with contributing authors from a broad range of disciplines.
Well-Being Factors for Different Industries: Tools for Determination
by Werner SeiferleinHealth management is one of the megatrends of our time. Healthy to its needs several factors. One factor is human well-being in general and, in particular, well-being in production-technical working environments. That is the focus of this investigation. For this purpose, an analysis of the current situation was created, which makes the topic applicable to other industries and areas. In this book, well-being is understood as the heading for a puzzle picture, with each researched or empirically found feel-good factor representing a piece of the puzzle. With the assembled puzzle picture, you are then able to create individual puzzle pictures for each industry.
Well Connected: Everyday Water Practices in Cairo (Water and Society)
by Tessa FarmerHow a community in Cairo, Egypt, has adapted the many systems required for clean water.Who is responsible for ensuring access to clean potable water? In an urbanizing planet beset by climate change, cities are facing increasingly arid conditions and a precarious water future. In Well Connected, anthropologist Tessa Farmer details how one community in Cairo, Egypt, has worked collaboratively to adapt the many systems required to facilitate clean water in their homes and neighborhoods.As a community that was originally not included in Cairo's municipal systems, the residents of Ezbet Khairallah built their own potable water and wastewater infrastructure. But when the city initiated a piped sewage removal system, local residents soon found themselves with little to no power over their own water supply or wastewater removal. Throughout this transition, residents worked together to collect water at the right times to drink, bathe, do laundry, cook, and clean homes. These everyday practices had deep implications for the health of community members, as they struggled to remain hydrated, rid their children of endemic intestinal worms, avoid consuming water contaminated with sewage, and mediate the impact of fluctuating water quality. Farmer examines how the people of Cairo interact with one another, with the government, and with social structures in order to navigate the water systems (and lack thereof) that affect their day-to-day lives. Farmer's extensive ethnographic fieldwork during the implementation of the Governorate of Cairo's septic system shines through in the compelling stories of community members. Well Connected taps into the inherent sociality of water through social contacts, moral ideology, interpersonal relationships, domestic rhythms, and the everyday labor of connecting.
"Well, Doc, You're In": Freeman Dyson’s Journey through the Universe
by Edited by David KaiserThe life and work of Freeman Dyson—renowned scientist, visionary, and iconoclast—and his particular way of thinking about deep questions.Freeman Dyson (1923–2020)—renowned scientist, visionary, and iconoclast—helped invent modern physics. Not bound by disciplinary divisions, he went on to explore foundational topics in mathematics, astrophysics, and the origin of life. General readers were introduced to Dyson&’s roving mind and heterodox approach in his 1979 book Disturbing the Universe, a poignant autobiographical reflection on life and science. &“Well, Doc, You&’re In&” (the title quotes Richard Feynman&’s remark to Dyson at a physics conference) offers a fresh examination of Dyson&’s life and work, exploring his particular way of thinking about deep questions that range from the nature of matter to the ultimate fate of the universe. The chapters—written by leading scientists, historians, and science journalists, including some of Dyson&’s colleagues—trace Dyson&’s formative years, his budding interests and curiosities, and his wide-ranging work across the natural sciences, technology, and public policy. They describe Dyson&’s innovations at the intersection of quantum theory and relativity, his novel nuclear reactor design (and his never-realized idea of a spacecraft powered by nuclear weapons), his years at the Institute for Advanced Study, and his foray into cosmology. In the coda, Dyson&’s daughter Esther reflects on growing up in the Dyson household. &“Well, Doc, You&’re In&” assesses Dyson&’s successes, blind spots, and influence, assembling a portrait of a scientist&’s outsized legacy.

A Well-Ordered Thing: Dmitrii Mendeleev and the Shadow of the Periodic Table, Revised Edition
by Professor Michael D. GordinDmitrii Mendeleev (1834–1907) is a name we recognize, but perhaps only as the creator of the periodic table of elements. Generally, little else has been known about him. A Well-Ordered Thing is an authoritative biography of Mendeleev that draws a multifaceted portrait of his life for the first time. As Michael Gordin reveals, Mendeleev was not only a luminary in the history of science, he was also an astonishingly wide-ranging political and cultural figure. From his attack on Spiritualism to his failed voyage to the Arctic and his near-mythical hot-air balloon trip, this is the story of an extraordinary maverick. The ideals that shaped his work outside science also led Mendeleev to order the elements and, eventually, to engineer one of the most fascinating scientific developments of the nineteenth century. A Well-Ordered Thing is a classic work that tells the story of one of the world’s most important minds.

Wellness Protocol for Smart Homes
by Hemant Ghayvat Subhas Chandra MukhopadhyayThis book focuses on the development of wellness protocols for smart home monitoring, aiming to forecast the wellness of individuals living in ambient assisted living (AAL) environments. It describes in detail the design and implementation of heterogeneous wireless sensors and networks as applied to data mining and machine learning, which the protocols are based on. Further, it shows how these sensor and actuator nodes are deployed in the home environment, generating real-time data on object usage and other movements inside the home, and therefore demonstrates that the protocols have proven to offer a reliable, efficient, flexible, and economical solution for smart home systems. Documenting the approach from sensor to decision making and information generation, the book addresses various issues concerning interference mitigation, errors, security and large data handling. As such, it offers a valuable resource for researchers, students and practitioners interested in interdisciplinary studies at the intersection of wireless sensing processing, radio communication, the Internet of Things and machine learning, and in how they can be applied to smart home monitoring and assisted living environments.
Wells to Wire: Life Cycle Assessment of Natural Gas-Fired Electricity
by Sarah Marie JordaanThis book presents an unbiased, comprehensive examination of the state of knowledge for life cycle assessments (LCAs) of natural gas-fired electricity, covering a suite of environmental impact categories. An exploration of the life cycle environmental impacts of gas-fired electricity is used to introduce the field of LCA, advancements in methods and data, and the limitations thereof. Natural gas, particularly as a fuel for electricity generation, serves as a dichotomy within energy and environmental systems analysis. While the cleanest burning fossil fuel, it is not without impacts, making it an excellent case study for introducing life cycle assessment. This book introduces readers to the field of LCA using natural gas-fired electricity as a case study, as well as providing a comprehensive review of the state of the art in life cycle data, research, and scientific debate related to this product system. The author also elucidates data and methodological challenges inherent to the field of LCA, exemplified using published research. The text explores how to conduct LCA, describing the analysis from the perspective of a numerator and denominator. With each chapter, the complexity of undertaking a LCA of gas-fired power is unravelled beyond a simple fraction to the expansive network of infrastructure examined in this type of research. Students, instructors, LCA practitioners, and energy professionals will benefit from not only the introduction to data and methods, but also this useful summary of the state of the art in the field. Policymakers and the interested public can learn more about the implications of LCA results for decision-support and the commentary about the economics of natural gas and its role as a bridge fuel. This book provides not only a useful reference, but also a springboard for researchers and experts interested in specializing in LCA, natural gas, or both.
Welsh Armorial Porcelain: Nantgarw and Swansea Crested China
by Howell G. EdwardsArmorial porcelains comprised the output of most European ceramics factories in the 18th and 19th Centuries in response to the large quantity of armorial porcelain services that were being imported from China bearing the coats of arms and crests of aristocratic families. Whereas these armorial services have been identified and covered for most porcelain manufactories the information relevant to their production by the two relatively short-lived Nantgarw and Swansea China Works has not been addressed as a theme until now. As an integral component of the holistic forensic appraisal of porcelain, a functional and decorative artwork manifestly part of our cultural heritage and its ongoing preservation , the recording and identification of such artefacts is material for the future establishment of a database of factory production . The Nantgarw and Swansea factories only operated for a limited period in the second decade of the 19th Century and their porcelains were much appreciated for their high quality and desirability by Georgian households. Today, examples are to be found in many museums and ceramics collections and continue to excite the interest of specialists and the general public . This text provides the first comprehensive assessment of armorial porcelains from these two factories and the methodology and procedure for the identification of unknown armorial bearings and crests is illustrated; individual bearings are discussed in detail and existing incorrect assignments in the literature are re-appraised. The difficulties in attribution of armorial heraldic achievements that are only minimally depicted are considered and directions for further studies using historical documentation are invoked. This book therefore fills a currently existing gap in the ceramics literature of the 19th Century.

Wendell Berry: Essays, 1969-1990 (Library of America Wendell Berry Edition #2)
by Wendell BerryThe first volume of the Library of America's definitive two-volume selection of the nonfiction writings of our greatest living advocate for sustainable culture.Writing with elegance and clarity, Wendell Berry is a compassionate and compelling voice for our time of political and cultural distrust and division, whether expounding the joys and wisdom of nonindustrial agriculture, relishing the pleasure of eating food produced locally by people you know, or giving voice to a righteous contempt for hollow innovation. He is our most important writer on the cultural crisis posed by industrialization and mass consumerism, and the vital role of rural, sustainable farming in preserving the planet as well as our national character. Now, in celebration of Berry's extraordinary six-decade-long career, Library of America presents a two-volume selection of his nonfiction writings prepared in close consultation with the author. This first volume collects thirty-three essays from nine different books, including his first, The Long-Legged House (1969), What are People For? (1990), with its still provocative essay "Why I am Not Going to Buy a Computer," and the complete text of his now classic The Unsettling of America (1975), whose argument about the enormous ecological, economic, and human costs of industrial agriculture has, as the author notes, "not had the happy fate of being proved wrong."Berry's essays remain timely, even urgent today, and will resonate with anyone interested in our relationship to the natural world and especially with a younger, politically engaged generation invested in the future welfare of the planet.INCLUDES: The Unsettling of America AND SELECTIONS FROM The Long-Legged House The Hidden Wound A Continuous Harmony Recollected Essays The Gift of Good Land Standing by Words Home Economics What Are People For?LIBRARY OF AMERICA is an independent nonprofit cultural organization founded in 1979 to preserve our nation’s literary heritage by publishing, and keeping permanently in print, America’s best and most significant writing.
