Fat

Fat: Fat. Such a little word evokes big responses. While 'fat' describes the size and shape of bodies—their appearance—our negative reactions to corpulence also depend on something tangible and tactile. As this book argues, there is more to fat than meets the eye. Fat: A Cultural History of the Stuff of Life offers reflections on how fat has been perceived and imagined in the West since antiquity. Featuring fascinating historical accounts as well as philosophical, religious, and cultural analyses—including discussions of status, gender, and race—the book digs deep into the past for the roots of our current notions and prejudices. Two central themes emerge: how we have perceived and imagined corpulent bodies over the centuries, and how fat—as a substance as well as a description of body size—has been associated with vitality and fertility as well as perceptions of animality. By exploring the complex ways in which fat, fatness, and fattening have been perceived over time, this book provides rich insights into the stuff our stereotypes are made of.

Plant Evolution

Plant Evolution: Although plants comprise more than 90% of all visible life, and land plants and algae collectively make up the most morphologically, physiologically, and ecologically diverse group of organisms on earth, books on evolution instead tend to focus on animals. This organismal bias has led to an incomplete and often erroneous understanding of evolutionary theory. Because plants grow and reproduce differently than animals, they have evolved differently, and generally accepted evolutionary views—as, for example, the standard models of speciation—often fail to hold when applied to them. Tapping such wide-ranging topics as genetics, gene regulatory networks, phenotype mapping, and multicellularity, as well as paleobotany, Karl J. Niklas’s Plant Evolution offers fresh insight into these differences. Following up on his landmark book The Evolutionary Biology of Plants—in which he drew on cutting-edge computer simulations that used plants as models to illuminate key evolutionary theories—Niklas incorporates data from more than a decade of new research in the flourishing field of molecular biology, conveying not only why the study of evolution is so important, but also why the study of plants is essential to our understanding of evolutionary processes. Niklas shows us that investigating the intricacies of plant development, the diversification of early vascular land plants, and larger patterns in plant evolution is not just a botanical pursuit: it is vital to our comprehe...

Democracy in the Time of Coronavirus

Democracy in the Time of Coronavirus: From a leading political thinker, this book is both an invaluable playbook for meeting our current moment and a stirring reflection on the future of democracy itself.   The COVID-19 pandemic has demonstrated some of the strengths of our society, including the rapid development of vaccines. But the pandemic has also exposed its glaring weaknesses, such as the failure of our government to develop and quickly implement strategies for tracing and containing outbreaks as well as widespread public distrust of government prompted by often confusing and conflicting choices—to mask, or not to mask. Even worse is that over half a million deaths and the extensive economic devastation could have been avoided if the government had been prepared to undertake comprehensive, contextually-sensitive policies to stop the spread of the disease.   In Democracy in the Time of Coronavirus, leading political thinker Danielle Allen untangles the US government’s COVID-19 victories and failures to offer a plan for creating a more resilient democratic polity—one that can better respond to both the present pandemic and future crises. Looking to history, Allen also identifies the challenges faced by democracies in other times that required strong government action. In an analysis spanning from ancient Greece to the Reconstruction Amendments and the present day, Allen argues for the relative effectiveness of collaborative federalism over authoritarian compulsion and for the unifying power of a comm...

The Arts of the Microbial World

The Arts of the Microbial World: The first in-depth study of Japanese fermentation science in the twentieth century. The Arts of the Microbial World explores the significance of fermentation phenomena, both as life processes and as technologies, in Japanese scientific culture. Victoria Lee’s careful study documents how Japanese scientists and skilled workers sought to use the microbe’s natural processes to create new products, from soy-sauce mold starters to MSG, vitamins to statins. In traditional brewing houses as well as in the food, fine chemical, and pharmaceutical industries across Japan, they showcased their ability to deal with the enormous sensitivity and variety of the microbial world.  Charting developments in fermentation science from the turn of the twentieth century, when Japan was an industrializing country on the periphery of the world economy, to 1980 when it had emerged as a global technological and economic power, Lee highlights the role of indigenous techniques in modern science as it took shape in Japan. In doing so, she reveals how knowledge of microbes lay at the heart of some of Japan’s most prominent technological breakthroughs in the global economy. At a moment when twenty-first-century developments in the fields of antibiotic resistance, the microbiome, and green chemistry suggest that the traditional eradication-based approach to the microbial world is unsustainable, twentieth-century Japanese microbiology provides a new, broader vantage for understanding and managing mic...

Freud’s Patients

Freud’s Patients: Portraits of the thirty-eight known patients Sigmund Freud treated clinically—some well-known, many obscure—reveal a darker, more complex picture of the famed psychoanalyst.   Everyone knows the characters described by Freud in his case histories: “Dora,” the “Rat Man,” the “Wolf Man.” But what do we know of the people, the lives behind these famous pseudonyms: Ida Bauer, Ernst Lanzer, Sergius Pankejeff? Do we know the circumstances that led them to Freud’s consulting room, or how they fared—how they really fared—following their treatments? And what of those patients about whom Freud wrote nothing, or very little: Pauline Silberstein, who threw herself from the fourth floor of her analyst’s building; Elfriede Hirschfeld, Freud’s “grand-patient” and “chief tormentor;” the fashionable architect Karl Mayreder; the psychotic millionaire Carl Liebmann; and so many others? In an absorbing sequence of portraits, Mikkel Borch-Jacobsen offers the stories of these men and women—some comic, many tragic, all of them deeply moving. In total, thirty-eight lives tell us as much about Freud’s clinical practice as his celebrated case studies, revealing a darker and more complex Freud than is usually portrayed: the doctor as his patients, their friends, and their families saw him.

Pushing Cool

Pushing Cool: Spanning a century, Pushing Cool reveals how the twin deceptions of health and Black affinity for menthol were crafted—and how the industry’s disturbingly powerful narrative has endured to this day. Police put Eric Garner in a fatal chokehold for selling cigarettes on a New York City street corner. George Floyd was killed by police outside a store in Minneapolis known as “the best place to buy menthols.” Black smokers overwhelmingly prefer menthol brands such as Kool, Salem, and Newport. All of this is no coincidence. The disproportionate Black deaths and cries of “I can’t breathe” that ring out in our era—because of police violence, COVID-19, or menthol smoking—are intimately connected to a post-1960s history of race and exploitation. In Pushing Cool, Keith Wailoo tells the intricate and poignant story of menthol cigarettes for the first time. He pulls back the curtain to reveal the hidden persuaders who shaped menthol buying habits and racial markets across America: the world of tobacco marketers, consultants, psychologists, and social scientists, as well as Black lawmakers and civic groups including the NAACP. Today most Black smokers buy menthols, and calls to prohibit their circulation hinge on a history of the industry’s targeted racial marketing. In 2009, when Congress banned flavored cigarettes as criminal enticements to encourage youth smoking, menthol cigarettes were also slated to be banned. Through a detaile...

From Data to Quanta

From Data to Quanta: The first comprehensive philosophical and historical account of the experimental foundations of Niels Bohr’s practice of physics. Niels Bohr was a central figure in quantum physics, well known for his work on atomic structure and his contributions to the Copenhagen interpretation of quantum mechanics. In this book, philosopher of science Slobodan Perović explores the way Bohr practiced and understood physics, and analyzes its implications for our understanding of modern science. Perović develops a novel approach to Bohr’s understanding of physics and his method of inquiry, presenting an exploratory symbiosis of historical and philosophical analysis that uncovers the key aspects of Bohr’s philosophical vision of physics within a given historical context. To better understand the methods that produced Bohr’s breakthrough results in quantum phenomena, Perović clarifies the nature of Bohr’s engagement with the experimental side of physics and lays out the basic distinctions and concepts that characterize his approach. Rich and insightful, Perović’s take on the early history of quantum mechanics and its methodological ramifications sheds vital new light on one of the key figures of modern physics.

Tropical Arctic

Tropical Arctic: An illustrated visit to the tropical arctic of 205 million years ago when Greenland was green. While today’s Greenland is largely covered in ice, in the time of the dinosaurs the area was a lushly forested, tropical zone. Tropical Arctic tracks a ten-million-year window of Earth’s history when global temperatures soared and the vegetation of the world responded. A project over eighteen years in the making, Tropical Arctic is the result of a unique collaboration between two paleobotanists, Jennifer C. McElwain and Ian J. Glasspool, and award-winning scientific illustrator Marlene Hill Donnelly. They began with a simple question: “What was the color of a fossilized leaf?” Tropical Arctic answers that question and more, allowing readers to experience Triassic Greenland through three reconstructed landscapes and an expertly researched catalog of extinct plants. A stunning compilation of paint and pencil art, photos, maps, and engineered fossil models, Tropical Arctic blends art and science to bring a lost world to life. Readers will also enjoy a front-row seat to the scientific adventures of life in the field, with engaging anecdotes about analyzing fossils and learning to ward off polar bear attacks.Tropical Arctic explains our planet’s story of environmental upheaval, mass extinction, and resilience. By looking at Earth’s past, we see a glimpse of the future of our warming planet—and learn an important lesson for our time of climate change.

Principles of Animal Behavior, 4th Edition

Principles of Animal Behavior, 4th Edition: Since the last edition of this definitive textbook was published in 2013, much has happened in the field of animal behavior. In this fourth edition, Lee Alan Dugatkin draws on cutting-edge new work not only to update and expand on the studies presented, but also to reinforce the previous editions’ focus on ultimate and proximate causation, as well as the book’s unique emphasis on natural selection, learning, and cultural transmission. The result is a state-of-the-art textbook on animal behavior that explains underlying concepts in a way that is both scientifically rigorous and accessible to students. Each chapter in the book provides a sound theoretical and conceptual basis upon which the empirical studies rest. A completely new feature in this edition are the Cognitive Connection boxes in Chapters 2–17, designed to dig deep into the importance of the cognitive underpinnings to many types of behaviors. Each box focuses on a specific issue related to cognition and the particular topic covered in that chapter. As Principles of Animal Behavior makes clear, the tapestry of animal behavior is created from weaving all of these components into a beautiful whole. With Dugatkin’s exquisitely illustrated, comprehensive, and up-to-date fourth edition, we are able to admire that beauty anew.

A Manual for Writers of Research Papers, Theses, and Dissertations, Ninth Edition

A Manual for Writers of Research Papers, Theses, and Dissertations, Ninth Edition: When Kate L. Turabian first put her famous guidelines to paper, she could hardly have imagined the world in which today’s students would be conducting research. Yet while the ways in which we research and compose papers may have changed, the fundamentals remain the same: writers need to have a strong research question, construct an evidence-based argument, cite their sources, and structure their work in a logical way. A Manual for Writers of Research Papers, Theses, and Dissertations—also known as “Turabian”—remains one of the most popular books for writers because of its timeless focus on achieving these goals. This new edition filters decades of expertise into modern standards. While previous editions incorporated digital forms of research and writing, this edition goes even further to build information literacy, recognizing that most students will be doing their work largely or entirely online and on screens. Chapters include updated advice on finding, evaluating, and citing a wide range of digital sources and also recognize the evolving use of software for citation management, graphics, and paper format and submission. The ninth edition is fully aligned with the recently released Chicago Manual of Style, 17th edition, as well as with the latest edition of The Craft of Research. Teachers and users of the previous editions will recognize the familiar three-part structure. Part 1 covers every step of the research and writing process, including%...

The Chicago Manual of Style, 17th Edition

The Chicago Manual of Style, 17th Edition: Technologies may change, but the need for clear and accurate communication never goes out of style. That is why for more than one hundred years The Chicago Manual of Style has remained the definitive guide for anyone who works with words. In the seven years since the previous edition debuted, we have seen an extraordinary evolution in the way we create and share knowledge. This seventeenth edition of The Chicago Manual of Style has been prepared with an eye toward how we find, create, and cite information that readers are as likely to access from their pockets as from a bookshelf. It offers updated guidelines on electronic workflows and publication formats, tools for PDF annotation and citation management, web accessibility standards, and effective use of metadata, abstracts, and keywords. It recognizes the needs of those who are self-publishing or following open access or Creative Commons publishing models. The citation chapters reflect the ever-expanding universe of electronic sources—including social media posts and comments, private messages, and app content—and also offer updated guidelines on such issues as DOIs, time stamps, and e-book locators. Other improvements are independent of technological change. The chapter on grammar and usage includes an expanded glossary of problematic words and phrases and a new section on syntax as well as updated guidance on gender-neutral pronouns and bias-free language. Key sections on punctuation and basic citation style have been%...

Doing Honest Work in College, Third Edition

Doing Honest Work in College, Third Edition: Doing Honest Work in College stands on three principles: do the work you say you do, give others credit, and present your research fairly. These are straightforward concepts, but the abundance of questionable online sources and temptation of a quick copy-paste can cause confusion as to what’s considered citing and what’s considered cheating. This guide starts out by clearly defining plagiarism and other forms of academic dishonesty and then gives students the tools they need to avoid those pitfalls. This edition addresses the acceptable use of mobile devices on tests, the proper approach to sources such as podcasts or social media posts, and the limitations of citation management software.
