Altruism in Cross-Cultural Perspective (International and Cultural Psychology)
by Douglas A. VakochAltruism in Cross-Cultural Perspective provides such a scholarly overview, examining the intersection of culture and such topics as evolutionary accounts of altruism and the importance of altruism in ritual and religion. The past decade has seen a proliferation of research on altruism, made possible in part by significant funding from organizations such as the John Templeton Foundation. While significant research has been conducted on biological, social, and individual dimensions of altruism, there has been no attempt to provide an overview of the ways that altruistic behavior and attitudes vary across cultures. The book addresses the methodological challenges of researching altruism across cultures, as well as the ways that altruism is manifest in difficult circumstances. A particular strength of the book is its attention to multiple disciplinary approaches to understanding altruism, with contributors from fields including psychology, anthropology, sociology, biology, communication, philosophy, religious studies, gender studies, and bioethics.

Alzheimer's Disease I
by Juan Moises de la Serna Adriana Ethel AllendeWhat is it, what are its causes, what consequences does it entail? Discover all the answers to Alzheimer's disease. Alzheimer's is a disease that has increased in terms of the number of cases affected in recent years, which in turn has caused many questions to arise when a person or a family member receives the diagnosis, such as, what Alzheimer's is, what its origin is, if there is a treatment, how the disease evolves, what the consequences in everyday life are, what the psychological effects on the patient are, if it can be overcome, if it is transmitted to children. This opens up a whole collection of issues to deal with in order to calm the uncertainty felt when getting to know that one suffers from a disease that is increasingly "common" and widespread, and of which little is known about the latest scientific advances in this area, due in large part to the complexity of the technical language used, but also because these advances usually reach only specialists through meetings and congresses where this type of information is shared.
Alzheimer's Disease and Frontotemporal Dementia: Methods and Protocols (Methods in Molecular Biology #670)

Alzheimer’s Disease II (Topics in Medicinal Chemistry #24)
by Michael S. WolfeMedicinal chemistry is both science and art. The science of medicinal chemistry offers mankind one of its best hopes for improving the quality of life. The art of medicinal chemistry continues to challenge its practitioners with the need for both intuition and experience to discover new drugs. Hence sharing the experience of drug research is uniquely beneficial to the field of medicinal chemistry. Drug research requires interdisciplinary team-work at the interface between chemistry, biology and medicine. Therefore, the topic-related series Topics in Medicinal Chemistry covers all relevant aspects of drug research, e. g. pathobiochemistry of diseases, identification and validation of (emerging) drug targets, structural biology, drugability of targets, drug design approaches, chemogenomics, synthetic chemistry including combinatorial methods, bioorganic chemistry, natural compounds, high-throughput screening, pharmacological in vitro and in vivo investigations, drug-receptor interactions on the molecular level, structure-activity relationships, drug absorption, distribution, metabolism, elimination, toxicology and pharmacogenomics. In general, special volumes are edited by well known guest editors
Alzheimer’s Disease Research: What Has Guided Research So Far and Why It Is High Time for a Paradigm Shift
by Christian BehlThis book highlights the key phases and central findings of Alzheimer’s Disease research since the introduction of the label ‘Alzheimer’s Disease’ in 1910. The author, Christian Behl, puts dementia research in the context of the respective zeitgeist and summarizes the paths that have led to the currently available Alzheimer’s drugs. As the reader is taken through the major developments in Alzheimer's Disease research, particularly over the past thirty years, Behl poses critical questions: Why are the exact causes of Alzheimer's Disease still in the dark, despite all the immense, worldwide research efforts in academia as well as in the pharmaceutical industry? Why has the majority of an entire research field kept focusing on a single hypothesis that establishes the deposition of the amyloid beta peptide in the brain as the key trigger of Alzheimer's pathology, even though this concept has still not been convincingly proven in the clinics? Are there other hypotheses that might explain the pathogenesis of this complex brain disease, and if so, why were these perspectives not adequately followed?In this book, Behl tries to answer these questions. Starting with the historical background, the author illustrates the long and arduous research journey, its numerous setbacks, and the many alternative explanations for the disease, which have started gaining increasing attention and acceptance in the Alzheimer’s research community only more recently. With his deep dive into the history and progression of this research, including the most recent developments, Behl explains why he believes that it is high time to promote a paradigm shift in Alzheimer’s Disease research.The book is written for all researchers in the fields of neurobiology and neurodegeneration, as well as other biomedical fields, who would like to gain a broad and beyond the surface insight into (the key developments of) one of the most promoted research fields of our time. With its extensive literature references and over 100 illustrations, the book is also attractive for students and interested lay persons. Elaborating on all the different aspects and research approaches of this research field, the author aims to convince the reader that the underlying causes of Alzheimer’s Disease may be much more complex than previously thought and that this must be considered for future research directions. While he hopes that the Alzheimer’s research community is finally ready to shed its ‘amyloid-straitjacket’ that has hampered progress for too long, he is also convinced that a much-needed paradigm shift can guide future Alzheimer’s Disease research and provide a new and broader perspective on this age-dependent brain disease.
Am I Dreaming?: The New Science of Consciousness and How Altered States Reboot the Brain
by James KingslandWhen a computer goes wrong, we are told to turn it off and on again. In Am I Dreaming?, science journalist James Kingsland reveals how the human brain is remarkably similar. By rebooting our hard-wired patterns of thinking - through so-called 'altered states of consciousness' - we can gain new perspectives into ourselves and the world around us.From shamans in Peru to tech workers in Silicon Valley, Kingsland provides a fascinating tour through lucid dreams, mindfulness, hypnotic trances, virtual reality and drug-induced hallucinations. An eye-opening insight into perception and consciousness, this is also a provocative argument for how altered states can significantly boost our mental health.
Am I Making Myself Clear?: A Scientist's Guide to Talking to the Public
by Cornelia DeanWhat we don’t know can hurt us—and does so every day. Climate change, health care policy, weapons of mass destruction, an aging infrastructure, stem cell research, endangered species, space exploration—all affect our lives as citizens and human beings in practical and profound ways. But unless we understand the science behind these issues, we cannot make reasonable decisions—and worse, we are susceptible to propaganda cloaked in scientific rhetoric. To convey the facts, this book suggests, scientists must take a more active role in making their work accessible to the media, and thus to the public. In Am I Making Myself Clear? Cornelia Dean, a distinguished science editor and reporter, urges scientists to overcome their institutional reticence and let their voices be heard beyond the forum of scholarly publication. By offering useful hints for improving their interactions with policymakers, the public, and her fellow journalists, Dean aims to change the attitude of scientists who scorn the mass media as an arena where important work is too often misrepresented or hyped. Even more important, she seeks to convince them of the value and urgency of communicating to the public. Am I Making Myself Clear? shows scientists how to speak to the public, handle the media, and describe their work to a lay audience on paper, online, and over the airwaves. It is a book that will improve the tone and content of debate over critical issues and will serve the interests of science and society.

Amaranth Biology, Chemistry, and Technology
by Octavio Paredes-LopezThis book is devoted to amaranth, a plant to which 45 species are indigenous to the Mesoamerican region and 10 others originated in Africa, Asia, and Europe. Amaranth was the foundation of the extensive North and South American ancient civilizations and is still important in the agriculture of more recent Indian cultures. However, this plant nearly disappeared after the Spanish conquest. In view of the outstanding agronomic performance of the plant and the high nutritional value of the grain, it is now becoming an important crop in various regions of the world. Progress in the utilization of amaranth is directly related to scientific and technical information on its biological, physical, and chemical properties. Amaranth: Biology, Chemistry, and Technology begins with a chapter on the use of tissue culture, molecular biology, and genetic engineering techniques for crop improvement. The next few chapters deal with classical genetics, traditional plant breeding, and plant physiology. Following chapters review the properties of storage and leaf proteins, carbohydrates (especially starch), and seed oil. The potential of amaranth for new food products and popping is discussed, and commercialization and marketing of amaranth and its products are described. The book also emphasizes the outstanding nutritional properties of amaranth.
Amateur Telescope Making in the Internet Age: Finding Parts, Getting Help, and More (The Patrick Moore Practical Astronomy Series)
by Robert L. ClarkBuilding an astronomical telescope offers the amateur astronomer an exciting challenge, with the possibility of ending up with a far bigger and better telescope than could have been afforded otherwise. In the past, the starting point has always been the grinding and polishing of at least the primary mirror, a difficult and immensely time-consuming process. But now that the Internet has brought us together in a global village, purchasing off-the-shelf goods such as parabolic mirrors, eyepieces, lenses, and telescope tubes, is possible. There are also a vast number of used mirrors and lenses out there, and it is now possible to track them down almost anywhere in the world. Online stores and auction houses have facilitated commerce regarding all sorts of useful optical components at a reasonable price. This is a book about making telescopes from available parts. It provides guidance on where to look and what to look for in selecting items useful for telescope making and explains how to assemble these components to produce an excellent instrument on a tight budget. At one time, many amateurs made their own telescopes from home-made parts. In today's rushed world, that has almost become a lost art. The Internet offers a wonderful alternative to either buying a pricey scope fully assembled or making your own from scratch.
