Book Description
. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.

Public Opinion

Public Opinion PDF Author: Walter Lippmann
Publisher:
ISBN:
Category : Public opinion
Languages : en
Pages : 448

Book Description
In what is widely considered the most influential book ever written by Walter Lippmann, the late journalist and social critic provides a fundamental treatise on the nature of human information and communication. The work is divided into eight parts, covering such varied issues as stereotypes, image making, and organized intelligence. The study begins with an analysis of "the world outside and the pictures in our heads", a leitmotif that starts with issues of censorship and privacy, speed, words, and clarity, and ends with a careful survey of the modern newspaper. Lippmann's conclusions are as meaningful in a world of television and computers as in the earlier period when newspapers were dominant. Public Opinion is of enduring significance for communications scholars, historians, sociologists, and political scientists. Copyright © Libri GmbH. All rights reserved.

Publisher:
ISBN: 9781556434747
Category : Science
Languages : en
Pages : 231

Book Description
Acclaimed theorist and social scientist Donna Jeanne Haraway uses the work of pioneering developmental biologists Ross G. Harrison, Joseph Needham, and Paul Weiss as a springboard for a discussion about a shift in developmental biology from a vitalism-mechanism framework to organicism. The book deftly interweaves Thomas Kuhn's concept of paradigm change into this wide-ranging analysis, emphasizing the role of model, analogy, and metaphor in the paradigm and arguing that any truly useful theoretical system in biology must have a central metaphor.

Mitochondria and Anaerobic Energy Metabolism in Eukaryotes

Mitochondria and Anaerobic Energy Metabolism in Eukaryotes PDF Author: William F. Martin
Publisher: Walter de Gruyter GmbH & Co KG
ISBN: 3110612410
Category : Science
Languages : en
Pages : 269

Book Description
Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.

The Ecology of Human Development

The Ecology of Human Development PDF Author: Urie BRONFENBRENNER
Publisher: Harvard University Press
ISBN: 0674028848
Category : Psychology
Languages : en
Pages : 349

Book Description
Here is a book that challenges the very basis of the way psychologists have studied child development. According to Urie Bronfenbrenner, one of the world's foremost developmental psychologists, laboratory studies of the child's behavior sacrifice too much in order to gain experimental control and analytic rigor. Laboratory observations, he argues, too often lead to "the science of the strange behavior of children in strange situations with strange adults for the briefest possible periods of time." To understand the way children actually develop, Bronfenbrenner believes that it will be necessary to observe their behavior in natural settings, while they are interacting with familiar adults over prolonged periods of time. This book offers an important blueprint for constructing such a new and ecologically valid psychology of development. The blueprint includes a complete conceptual framework for analysing the layers of the environment that have a formative influence on the child. This framework is applied to a variety of settings in which children commonly develop, ranging from the pediatric ward to daycare, school, and various family configurations. The result is a rich set of hypotheses about the developmental consequences of various types of environments. Where current research bears on these hypotheses, Bronfenbrenner marshals the data to show how an ecological theory can be tested. Where no relevant data exist, he suggests new and interesting ecological experiments that might be undertaken to resolve current unknowns. Bronfenbrenner's groundbreaking program for reform in developmental psychology is certain to be controversial. His argument flies in the face of standard psychological procedures and challenges psychology to become more relevant to the ways in which children actually develop. It is a challenge psychology can ill-afford to ignore.

ISBN: 1317744837
Category : Psychology
Languages : en
Pages : 405

Book Description
A History of the Brain tells the full story of neuroscience, from antiquity to the present day. It describes how we have come to understand the biological nature of the brain, beginning in prehistoric times, and progressing to the twentieth century with the development of Modern Neuroscience. This is the first time a history of the brain has been written in a narrative way, emphasizing how our understanding of the brain and nervous system has developed over time, with the development of the disciplines of anatomy, pharmacology, physiology, psychology and neurosurgery. The book covers: beliefs about the brain in ancient Egypt, Greece and Rome the Medieval period, Renaissance and Enlightenment the nineteenth century the most important advances in the twentieth century and future directions in neuroscience. The discoveries leading to the development of modern neuroscience gave rise to one of the most exciting and fascinating stories in the whole of science. Written for readers with no prior knowledge of the brain or history, the book will delight students, and will also be of great interest to researchers and lecturers with an interest in understanding how we have arrived at our present knowledge of the brain.
