The senses can be powerful triggers for memories of our past,
eliciting a range of both positive and negative emotions. The smell
or taste of a long forgotten sweet can stimulate a rich emotional
response connected to our childhood, or a piece of music transport
us back to our adolescence. Sense memories can be linked to all the
senses - sound, vision, and even touch can also trigger intense and
emotional memories of our past.
Advances in genomics and biotechnology are enabling quantum leaps in the understanding of soybean molecular biology. The problems that face the soybean industry also are diversifying and escalating on a global scale. Designing Soybeans for 21st Century outlines current and emerging barriers in the global soybean market, principally: 1) long-term ability to sustain production to meet continued growth in demand for soybean and soybean products; 2) governmental and legislative policies; 3) global access to advances in soybean technology; and 4) customer and consumer trends in the use of soybean products. The book also addresses state-of-art steps that should help move soybeans past these market barriers as advances in genomics and genetic engineering are deployed to design soybeans and soybean products that meet the challenges of 21st century markets.
For over thirty years Susan Wolf has been writing about moral and nonmoral values and the relation between them. This volume collects Wolf's most important essays on the topics of morality, love, and meaning, ranging from her classic essay "Moral Saints" to her most recent "The Importance of Love." Wolf's essays warn us against the common tendency to classify values in terms of a dichotomy that contrasts the personal, self-interested, or egoistic with the impersonal, altruistic or moral. On Wolf's view, this tendency ignores or distorts the significance of such values as love, beauty, and truth, and neglects the importance of meaningfulness as a dimension of the good life. These essays show us how a self-conscious recognition of the variety of values leads to new understandings of the point, the content, and the limits of morality and to new ways of thinking about happiness and well-being.
Despite the massive scale of global inequalities, until recently few political philosophers or bioethicists addressed their ethical implications. Questions of justice were thought to be primarily internal to the nation state. Over the last decade or so, there has been an explosion of interest in the philosophical issues surrounding global justice. These issues are of direct relevance to bioethics. The links between poverty and health imply that we cannot separate questions of global health from questions about fair distribution of global resources and the institutions governing the world order. Similarly, as increasing numbers of medical trials are conducted in the developing world, researchers and their sponsors have to confront the special problems of doing research in an unjust world, with corresponding obligations to correct injustice and avoid exploitation. This book presents a collection of original essays by leading thinkers in political theory, philosophy, and bioethics. They address the key issues concerning global justice and bioethics from two perspectives. The first is ideal theory, which is concerned with the social institutions that would regulate a just world. What is the relationship between human rights and the provision of health care? How, if at all, should a global order distinguish between obligations to compatriots and others? The second perspective is from non-ideal theory, which governs how people should behave in the unjust world in which we actually find ourselves. What sort of medical care should actual researchers working in impoverished countries offer their subjects? What should NGOs do in the face of cultural practices with which they deem unethical? If coordinated international action will not happen, what ought individual states to do? These questions have more than theoretical interest; their answers are of direct practical import for policymakers, researchers, advocates, NGOs, scholars, and others. This book is the first collection to comprehensively address the intersection of global justice and bioethical dilemmas.
While scholars typically view Plato's engagement with medicine as uniform and largely positive, Susan B. Levin argues that from the Gorgias through the Laws, his handling of medicine unfolds in several key phases. Further, she shows that Plato views medicine as an important rival for authority on phusis (nature) and eudaimonia (flourishing). Levin's arguments rest on careful attention both to Plato and to the Hippocratic Corpus. Levin shows that an evident but unexpressed tension involving medicine's status emerges in the Gorgias and is explored in Plato's critiques of medicine in the Symposium and Republic. In the Laws, however, this rivalry and tension dissolve. Levin addresses the question of why Plato's rivalry with medicine is put to rest while those with rhetoric and poetry continue. On her account, developments in his views of human nature, with their resulting impact on his political thought, drive Plato's striking adjustments involving medicine in the Laws. Levin's investigation of Plato is timely: for the first time in the history of bioethics, the value of ancient philosophy is receiving notable attention. Most discussions focus on Aristotle's concept of phronesis (practical wisdom); here, Levin argues that Plato has much to offer bioethics as it works to address pressing concerns about the doctor-patient tie, medical professionalism, and medicine's relationship to society.
Now published by "Academic Press" and revised from the author's previous "Five Kingdoms, Third Edition", this extraordinary, all inclusive catalogue of the world's living organisms describes the diversity of the major groups, or phyla, of nature's most inclusive taxa. Developed after consultation with specialists, this modern classification scheme is consistent both with the fossil record and with recent molecular, morphological and metabolic data. Generously illustrated, now in full color, "Kingdoms and Domains" is remarkably easy to read. It accesses the full range of life forms that still inhabit our planet and logically and explicitly classifies them according to their evolutionary relationships. Definitive characteristics of each phylum are professionally described in ways that, unlike most scientific literature, profoundly respect the needs of educators, students and nature lovers. This work is meant to be of interest to all evolutionists as well as to conservationists, ecologists, genomicists, geographers, microbiologists, museum curators, oceanographers, paleontologists and, especially nature lovers whether artists, gardeners or environmental activists. "Kingdoms and Domains" is a unique and indispensable reference for anyone intrigued by a planetary phenomenon: the spectacular diversity of life, both microscopic and macroscopic, as we know it only on Earth today. This work also carries: new foreword by Edward O. Wilson; the latest concepts of molecular systematics, symbiogenesis, and the evolutionary importance of microbes; newly expanded chapter openings that define each kingdom and place its members in context in geological time and ecological space; definitions of terms in the glossary and throughout the book; ecostrips, illustrations that place organisms in their most likely environments such as deep sea vents, tropical forests, deserts or hot sulfur springs; and, a new table that compares features of the most inclusive taxa. This book shows an application of a logical, authoritative, inclusive and coherent overall classification scheme based on evolutionary principles.
The book is based on data collected during the past 10 years by
Zackenberg Ecological Research Operations (ZERO) at Zackenberg
Research Station in northeast Greenland. This volume covers the
function of Arctic ecosystems based on the most comprehensive
long-term data set in the world from a well-defined Arctic
ecosystem. Editors offer a comprehensive and authoritative analysis
of how climate variability is influencing an Arctic ecosystem and
how the Arctic ecosystems have inherent feedback mechanisms
interacting with climate variability or change.
Levels of mycotoxin contamination in agricultural commodities are
regulated in more than 100 countries, and exposure to these
naturally occurring toxins presents serious risks to the health of
humans and animals with negative impacts to commodity values. This
symposium series book presents significant scientific developments
in the multifaceted approach to reducing exposure to these
naturally occurring toxins. A broad-spectrum of subject matter of
the multidisciplinary field of mycotoxin research is conveniently
compiled in this single volume, and general themes include
prevention, control, exposure, molecular biology, biosynthesis,
analytical methodology, and emerging techniques. The book opens
with an overview of prevention of mycotoxin production by means of
biological control and human exposure to contaminated foods,
including tofu, apples, figs, and a broad range of fruits.
In the last fifteen years, there has been significant interest in studying the brain structures involved in moral judgments using novel techniques from neuroscience such as functional magnetic resonance imaging (fMRI). Many people, including a number of philosophers, believe that results from neuroscience have the potential to settle seemingly intractable debates concerning the nature, practice, and reliability of moral judgments. This has led to a flurry of scientific and philosophical activities, resulting in the rapid growth of the new field of moral neuroscience. There is now a vast array of ongoing scientific research devoted towards understanding the neural correlates of moral judgments, accompanied by a large philosophical literature aimed at interpreting and examining the methodology and the results of this research. This is the first volume to take stock of fifteen years of research of this fast-growing field of moral neuroscience and to recommend future directions for research. It features the most up-to-date research in this area, and it presents a wide variety of perspectives on this topic.
Although we no longer live in the relative simplicity of the
Jurassic age, and even though we are not aware of them, primitive
mammalian brain that developed in that era still live on inside our
skulls and remain crucial to our daily functions. The challenges we
face today in the information age--how to process the vastly
greater, more varied and quickly changing inputs we receive--are
very different from those that our ancestors faced during the
Jurassic age. As we struggle to process overwhelming amounts of
information, we may sometimes ask whether our brains can change to
help us adapt. In fact, our brains have always changed gradually,
so the questions we should ask are really how our brains will
change, and whether we will be able to take full advantage of the
changes, perhaps even enhance them, to help us keep up with the
accelerating evolution of machines. To understand how our brains
will change, we need to understand how they evolved in the first
place, as well as how the interactions of the resulting brain
structures, including the relics of primitive mammalian and even
reptilian processes, influence how we think and act.
The book is based on data collected during the past ten years by

Research Station in Northeast Greenland. This volume covers the
function of Arctic ecosystems based on the most comprehensive
long-term data set in the world from a well-defined Arctic
ecosystem. Editors offer a comprehensive and authoritative analysis

This textbook provides a thorough and comprehensive overview of the
human brain and spinal cord for medical and graduate students as
well as residents in the clinical neurosciences. Standing on the
shoulders of training from outstanding scientist-teacher mentors
and based on more than 30 years of experience teaching about the
brain and spinal cord to medical and graduate students, this single
authored text presents everything the reader would need as they
begin their study of the nervous system. At the same time the
experienced neuroscientist will find much useful and valuable
information in these pages that is based almost exclusively on
studies in experimental primates and observations in humans. Every
effort has been made to present the complexities of the nervous
system as simply and clearly as possible. The careful reader will
discover a clarity and depth of coverage that makes the reading
both instructional and enjoyable. Topics are presented logically
and the text in an easy-to-read style. The accompanying line
drawings emphasize important concepts in a clear and uncluttered
manner.
Cognitive psychology has matured and flourished in the last half-century, as new theories, research tools, and theoretical frameworks have allowed cognitive psychologists and researchers to explore a broad array of topics. In the same vein, the depth of understanding and the methodological and theoretical sophistication have also grown in wonderful ways. Given the expanse of the field, an up-to-date and inclusive resource such as this handbook is needed for aspiring generalists who wish to read the book cover to cover, and for the many readers who are simply curious to know the current happenings in other cognition laboratories. Guided by this need, this volume's 64 chapters cover all aspects of cognition, spanning perceptual issues, attention, memory, knowledge representation, language, emotional influences, judgment, problem solving, and the study of individual differences in cognition. Additional chapters turn to the control of complex actions and the social, cultural, and developmental context of cognition. The authors include a mix of well-established influential figures and younger colleagues in order to gain an understanding of the field's forward trajectory. The volume also includes a mix of "tutorial" chapters and chapters that powerfully represent a particular research team's point of view.
Many people believe that pleasure and desire are obstacles to reasonable and intelligent behavior. In The Pleasure Center, Morten Kringelbach reveals that what we desire, what pleases us--in fact, our most base, animalistic tendencies--are actually very important sources of information. They motivate us for a good reason. And understanding that reason, taking that reason into account, and harnessing and directing that reason, can make us much more rational and effective people. In exploring the many facets of pleasure, desire and emotion, Kringelbach takes us through the whole spectrum of human experience, such as how emotion fuels our interest in things, allowing us to pay attention and learn. He investigates the reward systems of the brain and sheds light on some of the most interesting new discoveries about pleasure and desire. Kringelbach concludes that if we understand and accept how pleasure and desire arise in the complex interaction between the brain's activity and our own experiences, we can discover what helps us enjoy life, enabling us to make better decisions and, ultimately, lead happier lives.
Galvani's Spark chronicles the gradual understanding of the nerve
impulse which is the basis of all thoughts, sensations and actions.
The story begins with Luigi Galvani's chance observation of a spark
from a friction machine causing a frog's leg to twitch from across
the room. The accurate recording and the understanding of the
properties of the nerve fiber membrane that makes the impulse
possible became the objectives of neuroscientists for over 200
years.
This book should be of value to anyone interested in bird evolution
and taxonomy, biogeography, distributional history, dispersal and
migration patterns. It provides an up-to-date synthesis of current
knowledge on species formation, and the factors influencing current
distribution patterns. It draws heavily on new information on Earth
history, including past glacial and other climatic changes, on new
developments in molecular biology and palaeontology, and on recent
studies of bird distribution and migration patterns, to produce a
coherent account of the factors that have influenced bird species
diversity and distribution patterns worldwide.
Recent years have seen the rise of a remarkable partnership between
the social and computational sciences on the phenomena of emotions.
Rallying around the term Affective Computing, this research can be
seen as revival of the cognitive science revolution, albeit garbed
in the cloak of affect, rather than cognition. Traditional
cognitive science research, to the extent it considered emotion at
all, cases it as at best a heuristic but more commonly a harmful
bias to cognition. More recent scholarship in the social sciences
has upended this view.
Our ability to map and intervene in the structure of the human
brain is proceeding at a very quick rate. Advances in psychiatry,
neurology, and neurosurgery have given us fresh insights into the
neurobiological basis of human thought and behavior. Technologies
like MRI and PET scans can detect early signs of psychiatric
disorders before they manifest symptoms. Electrical and magnetic
stimulation of the brain can non-invasively relieve symptoms of
obsessive-compulsive disorder, depression and other conditions
resistant to treatment, while implanting neuro-electrodes can help
patients with Parkinsons and other motor control-related diseases.
New drugs can help regenerate neuronal connections otherwise
disrupted by schizophrenia and similar diseases.
In The Intelligent Movement Machine: An Ethological Perspective on the Primate Motor System, Michael Graziano offers a fundamentally new theory of motor cortex organization: the rendering of the movement repertoire onto the cortex. The action repertoire of an animal is highly dimensional, whereas the cortical sheet is two-dimensional. Rendering the action space onto the cortex therefore results in a complex pattern, explaining the otherwise inexplicable details of the motor cortex organization. This clearly written book book includes a complete history of motor cortex research from its discovery to the present, a discussion of the major issues in motor cortex research, and an account of recent experiments that led to Graziano's "action map" view. Though focused on the motor cortex, the book includes a range of topics from an explanation of how primates put food in their mouths, to the origins of social beahvior such as smiling and laughing, to the mysterious link between movement disorders and autism. This book is written for a general audience, and should be of interest to experts, students, and the scientific lay.
DNA sequence specificity is a sub-specialty in the general area of
molecular recognition. This area includes macromolecular-molecular
interactions (e.g., protein-DNA), oligomer-DNA interacitons (e.g.,
triple strands), and ligand-DNA interactions (e.g., drug-DNA). It
is this latter group of DNA sequence specificity interactions that
is the subject of Volumes 1 and 2 of "Advances in DNA Sequence
Specific Agents." As was the case for Volume 1, Part A also covers
methodology, but in Volume 2 we include calorimetric titrations,
molecular modeling, X-ray crystallographic and NMR structural
studies, and transcriptional assays. Part B also follows the same
format as Volume 1 and describes the sequence specificities and
covalent and noncovalent interactions of small ligands with
DNA.
This practical book provides the detailed methodology and expert
guidance required for measuring and manipulating cytosolic ion
concentrations. In addition, the strengths, weaknesses, and
pitfalls of various techniques are presented. It is an invaluable
source for those needing an objective evaluation of current
methodologies and for those contemplating setting up such
procedures.
Gene probes, whether RNA or DNA, have played a central role in the rapid development of molecular biology. The wide variety of applications is matched by a considerable diversity in the methods used for generating probes, a complete account of which would be very difficult to make. Instead, this second volume in the series combines a selection of newer gene probe procedures with a review of the most important established methods, together with some examples of the ways in which gene probes can be applied. In doing so, the book aims to act not only as an introductory manual for newcomers to the field, but also as a means of broadening the horizons of existing researchers. |
