Sexual Selections: What We Can and Can't Learn about Sex from Animals
by Marlene ZukScientific discoveries about the animal kingdom fuel ideological battles on many fronts, especially battles about sex and gender. We now know that male marmosets help take care of their offspring. Is this heartening news for today's stay-at-home dads? Recent studies show that many female birds once thought to be monogamous actually have chicks that are fathered outside the primary breeding pair. Does this information spell doom for traditional marriages? And bonobo apes take part in female-female sexual encounters. Does this mean that human homosexuality is natural? This highly provocative book clearly shows that these are the wrong kinds of questions to ask about animal behavior. Marlene Zuk, a respected biologist and a feminist, gives an eye-opening tour of some of the latest developments in our knowledge of animal sexuality and evolutionary biology. Sexual Selections exposes the anthropomorphism and gender politics that have colored our understanding of the natural world and shows how feminism can help move us away from our ideological biases. As she tells many amazing stories about animal behavior--whether of birds and apes or of rats and cockroaches--Zuk takes us to the places where our ideas about nature, gender, and culture collide. Writing in an engaging, conversational style, she discusses such politically charged topics as motherhood, the genetic basis for adultery, the female orgasm, menstruation, and homosexuality. She shows how feminism can give us the tools to examine sensitive issues such as these and to enhance our understanding of the natural world if we avoid using research to champion a feminist agenda and avoid using animals as ideological weapons. Zuk passionately asks us to learn to see the animal world on its own terms, with its splendid array of diversity and variation. This knowledge will give us a better understanding of animals and can ultimately change our assumptions about what is natural, normal, and even possible.
Sexuality, Sociality, and Cosmology in Medieval Literary Texts
by Jennifer N. Brown Marla SegolThis edited volume contains nine articles exploring medieval sexuality and its relation to cosmological and social ordering. All of our authors analyze literary texts, both religious and secular, using a variety of critical methodologies. These include discourse theory, psychoanalytic criticism, queer theory, masculinity studies, and new historicist methodologies, among others. However, we all begin with the notion that medieval sexuality is distinct from our own conceptions of it, and that the one of the most important factors in considering its difference is its conceptualization in terms of social and cosmological ordering. Medieval people ordered their communities differently than contemporary people do, and they conceptualized their relationship to them based on different cosmological models that the ones we currently use. As a result, they thought of sexuality differently as well. This volume explores the relation between sexuality, social taxonomies, and cosmology in medieval religious and secular literature, as well as the various contemporary methodologies available for conceptualizing this. Its theoretical importance lies in this dual focus, which will render the collection useful to a wide audience of students and teachers of medieval literature, religion and history, as well as to those interested in the history of sexuality generally.

Shadow Medicine: The Placebo in Conventional and Alternative Therapies
by Jr. John HallerCan Evidence Based Medicine (EBM) and Complementary and Alternative Medicine (CAM) find common ground? A distinguished historian of medicine, John S. Haller Jr., explores the epistemological foundations of EBM and the challenges these conceptual tools present for both conventional and alternative therapies. As he explores a possible reconciliation between their conflicting approaches, Haller maintains a healthy, scientific skepticism yet finds promise in select complementary and alternative (CAM) therapies. Haller elucidates recent research on the placebo effect and shows how a new engagement between EBM and CAM might lead to a more productive medical practice that includes both the objectivity of evidence-based medicine and the subjective truth of the physician-patient relationship. Haller's book tours key topics in the standoff between EBM and CAM: how and why the double blinded, randomized clinical trial (RCT) came to be considered the gold standard in modern medicine; the challenge of postmodern medicine as it counters the positivism of evidence-based medicine; and the politics of modern CAM and the rise of the National Center for Complementary and Alternative Medicine. He conducts an in-depth case study of homeopathy, explaining why it has emerged as a poster-child for CAM, and assesses CAM's popularity despite its poor performance in clinical trials. Haller concludes with hope, showing how new experimental protocols might tease out the evidentiary basis for the placebo effect and establish a foundation for some reconciliation between EBM and CAM.
Shadow of a Hero
by Peter DickinsonTo save a country, a girl and her grandfather must learn what it means to be a hero The greatest hero in the history of Varina was baptized in a cave. Every schoolchild knows the story. His parents were on their way to the city when a storm drove them to take shelter in the mountainside, along with a priest, a bandit, and a scholar. When the storm did not abate, they asked the priest to give their child a name, and he christened the boy Restaur Vax. The boy would grow to be a warrior, a scholar, and a man of god, and his name would lead an oppressed people to independence for the first time. Alas, that liberty would not survive. Generations later, Vax's oldest living descendant is in London, teaching the language of Varina to his inquisitive young granddaughter. When his homeland is torn apart once more by war, calls come for this man to take up the mantle of the Vax name--and become a hero for a new age. This ebook features an illustrated personal history of Peter Dickinson including rare images from the author's collection.

Shadows
by Roberto CasatiIn this original, wide-ranging, and endlessly thought-provoking work of popular nonfiction, a leading science writer uncovers the pervasive presence of shadows in our world.For Plato, shadows were the symbol of our limitations. For Galileo, they knocked the Earth from the center of the cosmos. They are a source of fear and a symbol of ignorance, and they loom large in art and design, mythology and folklore, physics and metaphysics, and architecture and urban planning. From shadows puppets and the psychology of shadows to the role of shadows in astronomy and the influence of shadows on the architectural profiles of our cities, Roberto Casati awakens our fascination in this tour-de-force of investigation and imagination.From the Trade Paperback edition.
Shadows Bright As Glass: The Extraordinary Transformation of One Man's Brain - and the Neuroscience that Makes Us Who We Are
by Amy Ellis NuttFrom Pulitzer-Prize-finalist Amy Ellis Nutt, comes the moving and inspiring story of Jon Sarkin. Sarkin's personality dramatically changed after he underwent experimental brain surgery and suffered a massive stroke. Remarkably, he could still remember his old self. Yet, once an ordinary family man, he suddenly found himself compelled to make art, always feverishly creating and only existing in the present. He has since gone on to become an acclaimed artist. Sarkin's story is beautifully interspersed with fascinating nuggets of history about man's struggle to understand the brain and the fragile nature of identity.
Shadows Bright as Glass
by Amy E NuttOn a sunny fall afternoon in 1988, Jon Sarkin was playing golf when, without a whisper of warning, his life changed forever. As he bent down to pick up his golf ball, something strange and massive happened inside his head; part of his brain seemed to unhinge, to split apart and float away. For an utterly inexplicable reason, a tiny blood vessel, thin as a thread, deep inside the folds of his gray matter had suddenly shifted ever so slightly, rubbing up against his acoustic nerve. Any noise now caused him excruciating pain. After months of seeking treatment to no avail, in desperation Sarkin resorted to radical deep-brain surgery, which seemed to go well until during recovery his brain began to bleed and he suffered a major stroke. When he awoke, he was a different man. Before the stroke, he was a calm, disciplined chiropractor, a happily married husband and father of a newborn son. Now he was transformed into a volatile and wildly exuberant obsessive, seized by a manic desire to create art, devoting virtually all his waking hours to furiously drawing, painting, and writing poems and letters to himself, strangely detached from his wife and child, and unable to return to his normal working life. His sense of self had been shattered, his intellect intact but his way of being drastically altered. His art became a relentless quest for the right words and pictures to unlock the secrets of how to live this strange new life. And what was even stranger was that he remembered his former self. In a beautifully crafted narrative, award-winning journalist and Pulitzer Prize finalist Amy Ellis Nutt interweaves Sarkin's remarkable story with a fascinating tour of the history of and latest findings in neuroscience and evolution that illuminate how the brain produces, from its web of billions of neurons and chaos of liquid electrical pulses, the richness of human experience that makes us who we are. Nutt brings vividly to life pivotal moments of discovery in neuroscience, from the shocking "rebirth" of a young girl hanged in 1650 to the first autopsy of an autistic savant's brain, and the extraordinary true stories of people whose personalities and cognitive abilities were dramatically altered by brain trauma, often in shocking ways. Probing recent revelations about the workings of creativity in the brain and the role of art in the evolution of human intelligence, she reveals how Jon Sarkin's obsessive need to create mirrors the earliest function of art in the brain. Introducing major findings about how our sense of self transcends the bounds of our own bodies, she explores how it is that the brain generates an individual "self" and how, if damage to our brains can so alter who we are, we can nonetheless be said to have a soul. For Jon Sarkin, with his personality and sense of self permanently altered, making art became his bridge back to life, a means of reassembling from the shards of his former self a new man who could rejoin his family and fashion a viable life. He is now an acclaimed artist who exhibits at some of the country's most prestigious venues, as well as a devoted husband to his wife, Kim, and father to their three children. At once wrenching and inspiring, this is a story of the remarkable human capacity to overcome the most daunting obstacles and of the extraordinary workings of the human mind.
Shadows of Forgotten Ancestors
by Carl Sagan Ann Druyan"Dazzling...A feast. Absorbing and elegantly written, it tells of theorigins of life on earth, describes its variety and charaacter, and culminates in a discussion of human nature and teh complex traces ofhumankind's evolutionary past...It is an amazing story masterfully told."FINANCIAL TIMES (LONDON)World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a ROOTS for the human species, a lucid and riveting account of how humans got to be the way we are. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, SHADOWS OF FORGOTTEN ANCESTORS is a triumph of popular science.From the Trade Paperback edition.
Shadows of Reality: The Fourth Dimension in Relativity, Cubism, and Modern Thought
by Tony RobbinIn this insightful book, which is a revisionist math history as well as a revisionist art history, Tony Robbin, well known for his innovative computer visualizations of hyperspace, investigates different models of the fourth dimension and how these are applied in art and physics. Robbin explores the distinction between the slicing, or Flatland, model and the projection, or shadow, model. He compares the history of these two models and their uses and misuses in popular discussions. Robbin breaks new ground with his original argument that Picasso used the projection model to invent cubism, and that Minkowski had four-dimensional projective geometry in mind when he structured special relativity. The discussion is brought to the present with an exposition of the projection model in the most creative ideas about space in contemporary mathematics such as twisters, quasicrystals, and quantum topology. Robbin clarifies these esoteric concepts with understandable drawings and diagrams. Robbin proposes that the powerful role of projective geometry in the development of current mathematical ideas has been long overlooked and that our attachment to the slicing model is essentially a conceptual block that hinders progress in understanding contemporary models of spacetime. He offers a fascinating review of how projective ideas are the source of some of today's most exciting developments in art, math, physics, and computer visualization.
