The current popular and scientific interest in virtual environments has provided a new impetus for investigating binaural and spatial hearing. However, the many intriguing phenomena of spatial hearing have long made it an exciting area of scientific inquiry. Psychophysical and physiological investigations of spatial hearing seem to be converging on common explanations of underlying mechanisms. These understandings have in turn been incorporated into sophisticated yet mathematically tractable models of binaural interaction. Thus, binaural and spatial hearing is one of the few areas in which professionals are soon likely to find adequate physiological explanations of complex psychological phenomena that can be reasonably and usefully approximated by mathematical and physical models. This volume grew out of the Conference on Binaural and Spatial Hearing, a four-day event held at Wright-Patterson Air Force Base in response to rapid developments in binaural and spatial hearing research and technology. Meant to be more than just a proceedings, it presents chapters that are longer than typical proceedings papers and contain considerably more review material, including extensive bibliographies in many cases. Arranged into topical sections, the chapters represent major thrusts in the recent literature. The authors of the first chapter in each section have been encouraged to take a broad perspective and review the current state of literature. Subsequent chapters in each section tend to be somewhat more narrowly focused, and often emphasize the authors' own work. Thus, each section provides overview, background, and current research on a particular topic. This book is significant in that it reviews the important work during the past 10 to 15 years, and provides greater breadth and depth than most of the previous works.

Awarded the W. W. Howells Award for the Outstanding Book in Biological Anthropology, this volume presents a comprehensive, integrated, and up-to-date overview of the major physiological and behavioral factors affecting human reproduction. In attempting to identify the most important causes of variation in fertility within and among human populations, Wood summarizes data from a wide range of societies. Trained as an anthropologist as well as a demographer, he devotes special attention to so-called "natural fertility" populations, in which modern contraceptives and induced abortion are not used to limit reproductive output. Such an emphasis enables him to study the interaction of biology and behavior with particular clarity. The volume weaves together the physiological, demographic, and biometric approaches to human fertility in a way that will encourage future interdisciplinary research. Instead of offering a general overview, the focus is to answer one question: Why does fertility and the number of live births vary from couple to couple within any particular population, and from population to population across the human species as a whole? Topics covered include ovarian function, conception and pregnancy, intrauterine mortality, reproductive maturation and senescence, coital frequency and the waiting time to conception, marriage patterns and the initiation of reproduction, the fertility-reducing effects of breastfeeding, the impact of maternal nutrition on reproduction, and reproductive seasonality. This unique combination of comprehensive subject matter and an integrated analytical approach makes the book ideally suited both as a graduate-level textbook and as a reference work.

Since the early decades of the 20th century, the notion of the hormonally-constructed body has become the dominant mode of conceptualizing bodies, particularly female bodies, to such an extent that it is often assumed to be a natural phenomenon. This book challenges the idea that there is such a thing as a "natural" body and demonstrates that it is the process by which scientific claims achieve universal status that constructs such discourses as natural facts. The work tells the story of scientists' search for the many tons of ovaries, testes and urine that were required in experiments to develop the hormonal body concept. It traces the origins of sex hormones and follows their development through mass-production as drugs to their eventual transformation into the contraceptive pill.

Based on the "Guide to the Human Fertilisation and Embryology Act 1990," this volume reviews the regulation of assisted conception including complex moral issues such as abortion, embryo research and cloning. It offers a comprehensive guide to the 1990 legislation as well as important legal and technical developments since that time.

Ectogenesis refers to the artificial gestation of a fetus outside the womb. Despite certain advantages for women's reproductive liberty, feminist groups remain divided regarding this technology. This book argues that reproduction imposes unjust burdens on women, and thus the ideals of equal opportunity demand continued research into ectogenesis.

A collection of cutting-edge laboratory techniques for the study of trophoblast and placental biology. The techniques presented range from experimental animal models, to animal and human placental organ and cell culture systems, to morphological, biochemical, and molecular strategies for assessing trophoblast/placental growth, differentiation and function.

Highlights include strategies for the isolation and culture of trophoblast cells from primates, ruminants, and rodents, and precise guidance to the molecular and cellular analysis of the placental phenotype. A companion second volume concentrates on methods for investigating placental function.

Human Gonadotropins is a must-have reference for basic science researchers looking to maximize their knowledge in this specific field of study. Luteinizing hormone, follicle-stimulating hormone, and human chorionic gonadotropin are essential for reproduction and outlined in detail in this work, covering topics ranging from antibodies and immunoassays, to commercial products and standards, genetics, and receptors and intermediaries for gonadotropins. Dr. Laurence Cole has been recognized for his outstanding research throughout his illustrious career. He has received awards from the Institute for Anticancer Research, Biannual Prize for best research; American Association for Clinical Chemistry, Most Outstanding Research Contributor to Clinical Chemistry Prize; Gynecology Oncology, Outstanding Speaker Award; and International Society for Study of Trophoblastic Disease, Gold Medal for most outstanding research. This detailed resource compiles all the recent research together into one volume, with one consistent voice.

The overturning of Roe v Wade makes the ethical consideration of abortion more important than ever. Appealing to reason rather than religious belief, this book is the most comprehensive case against the choice of abortion yet published. This third edition of The Ethics of Abortion critically evaluates all the major grounds for denying basic rights to fetal human beings, including the views of those who defend not only abortion but also post-birth abortion. It also provides several (non-theological) justifications for the conclusion that all human beings, including those in utero, should be respected as persons. This book also critiques the view that abortion is not wrong even if the human fetus is a person. The Ethics of Abortion examines hard cases for those who are prolife, such as abortion in cases of rape or in order to save the woman's life, as well as hard cases for defenders of abortion, such as sex selection abortion and the rationale for being "personally opposed" but publicly supportive of abortion. It concludes with a discussion of whether artificial wombs might end the abortion debate. Answering the arguments of defenders of abortion, this book provides reasoned justification for the view that all intentional abortions are ethically wrong and that doctors and nurses who object to abortion should not be forced to act against their consciences. Updates and Revisions to the Third Edition Include: Discusses Achas Burin's 2014 essay, "Beyond Pragmatism: Defending the 'Bright Line' of Birth" in chapter 3 Incorporates into chapter 8 David Boonin's cogently argued 2019 book, Beyond Roe: Why Abortion Should be Legal - Even if the Fetus is a Person Expands chapter 9 to examine tragic cases in which prenatal diagnosis determines with certainty that a fetus will die shortly after birth Includes an updated and expanded section in chapter 11 on recent debates about conscience protections Considers in chapter 12 recent arguments that parents have a right to kill if the product of conception is in an artificial womb Updates statistics on numbers of abortions in the United States, including corrections to statistics that were once thought true but are now known as erroneous Updated bibliography

In a state-of-the-art synthesis of basic science and clinical practice, Roy Smith and a distinguished panel of researchers and clinicians review GH regulation and its action at the molecular level, and describe the basis for GH deficiency and the use of GH as therapy in a variety of clinical situations. The clinical presentation moves beyond the treatment of GH-deficient children to include the genetics of GH-deficiency, GH-deficiency in adults, osteoporosis, Syndrome X, sleep quality, GH in AIDS patients, GHRH in clinical studies. Timely and innovative, Human Growth Hormone: Research and Clinical Practice will benefit both basic and clinical researchers, as well as those clinical endocrinologists who want to use growth hormone not only in treating children, but also in treating adult disorders, including those associated with metabolic disease.

In the contemporary world, the unborn - human embryos and foetuses - are highly public and contested figures. Their visual images appear across a wide range of forums, from YouTube videos to pregnancy handbooks. They have become commercial commodities as part of the IVF industry, reproductive tourism and stem cell research and regenerative medicine. The unborn are the focus of intense debates concerning concepts of personhood and humanness, especially in relation to abortion politics and the use and disposal of embryos created outside the human body. The Social Worlds of the Unborn is the first book-length work to discuss all of these issues and more, drawing on social and cultural theory and research and empirical research to do so. It will be of interest to academics and students in a multitude of disciplines, including sociology, anthropology, philosophy, bioethics, gender studies, media and cultural studies and science and technology studies.

Recent developments of experimental techniques in cellular and molecular biology have made it possible to understand the molecular biology of male gametogenesis in greater detail. This book focuses on the description of specialized proteins, which are dominantly and/or specifically expressed in germ cells and localized in spermatozoa. There is an urgent need to classify proteins of spermatogenic cells with a view of their functions, and their applications in the regulation of fertility and in understanding infertility. The understanding of structural properties of male germ cell specific proteins can offer vulnerable points for targeted intervention in testis without generalized effects on stages of spermatogenesis. Besides targeted action in male germ cells, sperm specific proteins and polypeptides may also offer potential application in the development of a contraceptive vaccine.

Originally published in 1984 Reproductive Ritual examines fertility and re-production in pre-industrial England. The book discusses both through anthropological research and reviews of contemporary literature that conscious family limitation was practised before the nineteenth century. The volume describes a surprising number of rules, regulations, taboos, injunctions, charms and herbal remedies used to affect pregnancy, and shows the extent to which individual women and men were concerned with controlling the size of their families. The fertility levels in England - as in Western Europe as a whole - were a very long way from the biological maximum in these centuries, and the book discusses the various reasons why this was so. The book reviews traditional ideas concerning the relationship between procreation and pleasure, drawn from a range of contemporary sources and discusses ways in which earlier generations sought both to promote and limit fertility. The book also examines abortion and shows how much evidence there is for its actual practice during the period and of traditional views towards it. This book provides a detailed understanding of historical attitudes towards conception family planning in pre-industrial England.

The 26 recognized minor phyla comprise aberrant clades, as most of them terminate as blind offshoots. Untied from the discussion on their phylogenesis of minor phyla, this book is largely devoted, for the first time, to aspects of reproduction and development in minor phyletics. The minor phyla are not as speciose (1,795 species/phylum) as the major phyla (157,066 species/phylum) are. The accumulation of deleterious genes causes inbreeding depression among progenies arising from parthenogenesis, clonal multiplication and selfing hermaphrodites. The reason for the limited species diversity in minor phyla is traced to (i) eutelism in 65.7% of minor phyletics and (ii) existence of 21.6% clonals, (iii) 6.4% parthenogens and (iv) 1.2% selfing hermaphroditism. Gonochorism obligately requires motility to search for a mate. The combination of low motility and gonochorism from Placozoa to hemocoelomatic minor phyla has limited diversity to < 1,000 species. Over 19% of minor phyletics are hermaphrodites. With the need to manifest and maintain dual sexuality, fecundity of hermaphrodites may be reduced to 50% of that in gonochores. Adopting an array of strategies, < 100 hermaphrodites are selfers. In eutelics, mitotic division is ceased in somatic cells after hatching. For the first time, the prevalence of eutelism has been brought to light in numbers of all the six pseudocoelomate phyla and priapulids. Eutelism limits fecundity to 30-300 eggs in free-living pseudocoelomates, priapulids and possibly other hemocoelomates. In them, sperm production is less than that of egg production; as a result, a large fraction of their eggs is sterile. With a high proportion of non-eutelic gametic cells (35%), Nematoda and possibly Nematomorpha and Acanthocephala are more fecund than rotifers, in which the proportion is 15%. Briefly, the reasons for the limited species diversity in minor phyletics are traced to eutelism, parthenogenesis and clonal multiplication. Surprisingly, parthenogenesis and clonal multiplication mutually eliminate each other. This is also true of hermaphroditism and parthenogenesis. However, clonal multiplication is prevalent from structurally simplest Placozoa to the most complex Ascidiacea, except in pseudocoelomates and hemocoelomates. A limited number of cells and cell types, and the consequent structural simplicity facilitate manifestation of parthenogenesis in pseudocoelomates and parasitism in Mesozoa, Myxozoa, 59% of Nematoda, Nematomorpha, Acanthocephala and Pentastomida. Despite hermaphroditism, Bryozoa (5,700 species) and Ascidiacea (3,000 species) are speciose among minor phyla. For the first time, the importance of fusion of fragments or colonies - an event equivalent to gamete fusion at fertilization - is recognized as a source of new gene combination. Besides, the colonies in these minor phyla degenerate and regenerate more or less regularly. Only the fittest degenerated colonies may be rejuvenated and regenerated.

Ever wondered why your life and health can sometimes be so hard to control? Or why it seems so easy for other people? Mark Hanson and Lucy Green draw on their years of experience as scientists and educators to cut through the usual information on genetics and lifestyle to reveal the secrets of early development which start to make each of us unique, during our first 1,000 days from the moment of conception. Some surprising discoveries, based on little-known new research, show how events during our first 1,000 days make each of us who we are and explain how we control our bodies, processes that go way beyond just the genes which we inherited. Provoking new ways of thinking about being parents, this book empowers individuals and society to give the next generation the gift of a good start to life and future health.

Originally published in 1933 Functional Affinities of Man, Monkeys and Apes gives a taxonomic and phylogenetic survey and the findings of diverse experimental investigations of lemurs, monkeys, and apes. The book discusses the inter-relationships of different Primates and emphasizes seldom-used approaches to the question of primate phylogeny. The book attempts to show how little they have been systematically tried, and argues for a regard to the proper place of functional investigations in the study of the classification and evolution of Primates. This book will be of interest to anthropologists, scientists and historians alike.

A Probabilistic Model of the Genotype/Phenotype Relationship provides a new hypothesis on the relationship between genotype and phenotype. The main idea of the book is that this relationship is probabilistic, in other words, the genotype does not fully explain the phenotype. This idea is developed and discussed using the current knowledge on complex genetic diseases, phenotypic plasticity, canalization and others.

Originally published in 1960, The Future of Man is a chronicle of Professor Medwar's Reith lectures of 1959. The book outlines his predictions about the future estate of man, with the 'process of foretelling, rather than with what is actually foretold'. He asks, can we predict the future size of populations? What is the evidence and theoretical background for the belief that human intelligence is declining? Could human beings become uniformly excellent or is inborn diversity and inequality a necessary part of the texture of human populations? The lectures tried to answer these questions and attempts to end with a definition of the biological standing of man. This book will be of interest to anthropologists, biologists and natural historians.

Originally published in 1972, Homo Sapiens examines how humans emerged from among the millions of other species and achieved our unique position within the animal kingdom. The book examines what direction future evolution will take and what may be regarded as the 'meaning' of human existence. It stipulates that these are the questions for which no real basis of discussion existed before the 20th century, and at the time of publication, some were still without a definite answer. The book sets out analyse these questions and the continuing debate that has arisen from their study. This is an account of the uniqueness of man in the animal kingdom, how this uniqueness arose during evolution, and what traces of it can be detected in animals other than man. The book describes the mental and physical evolution of man, from his earliest ancestors to the present day. He also gives an account of man's cultural development seeking to establish that there is an underlying principal of cultural evolution, a principle that has been denied by many historians. Later chapters deal with the future and with possible forecasts of mankind's further physical, intellectual and cultural evolution.

Understanding immunology is increasingly important in obstetrics and gynecology. Written primarily to meet the needs of practicing obstetricians and gynecologists, this book explores the role of immunological processes in reproduction. It presents immunologic concepts and illustrates important points with examples familiar to the clinician. The book is organized into four sections that explore the fundamentals of the immune system, the immunological paradox of pregnancy, clinical applications of immunology in obstetric and gynecologic practice, and immunopathology in obstetric and gynecologic practice. Written mainly for practicing obstetricians and gynecologists, the research results cited in the book are based on human experimentation. Fully illustrated with clear schematic drawings that highlight important concepts and processes, The Immunology of Human Reproduction gives readers an essential overview of immunology as it relates to human reproduction.
