Book Description
The Biology of Stentor summarizes all that has been learned about the biology of a certain group of ciliate protozoa: the stentors. Topics covered range from form and function in Stentor to behavior, fine structure, growth and division, and reorganization. Regeneration is also discussed, along with polarity, metabolism, genetics, and primordium development. This volume is comprised of 20 chapters and begins with a characterization of Stentor, with emphasis on its particular advantages in addressing general problems of biology. The reader is then introduced to form and function in Stentor, particularly S. coeruleus. The following chapters focus on the behavior (food selection, swimming, response to light, etc.) of stentors and the fine points of structure in terms of which this behavior is to be explained and which demonstrate the highly complex and precise achievements of morphogenesis. The remaining chapters explore growth and division in Stentor as well as the course of reorganization and regeneration; development of the oral primordium and how it is activated and inhibited; rate of regeneration in relation to the polar axis; fusion masses of whole stentors; and reconstitution in disarranged stentors. Various species of Stentor are also described, together with the techniques used to study them. The final chapter deals with hypotheses concerning the morphogenesis of ciliates. This book will be of interest to students and practitioners of biology and physiology.

Book Description
For two decades, colleges and universities have regularly offered, and in some cases required, courses in thinking skills. Such courses generally have focused on training students in the basics of informal and formal logic, the assumption being that good thinking is logical thinking, and that instruction in critical or "good" thinking consequently should emphasize logical procedures. This "logistic" assumption is clearly reflected in both critical thinking textbooks as well as in the professional literature. Recently, however, the epistemic and pedagogical identification of critical thinking and logical thinking has been questioned by educators from a wide diversity of disciplines. Many of these critics argue that a richer, more comprehensive model of thinking itself is needed, one that acknowledges the importance of traditionally downplayed faculties such as empathy, imagination, and insight. Others contend that thinking skills theory and pedagogy must take into consideration the contextual and sometimes political influences upon not just content but also styles of thinking. finally still other critics of the conventional model of critical thinking argue that recent research in feminist studies sheds a great deal of light upon the directions in which critical thinking instruction should go. The fourteen essays in this anthology all illustrate this new way of thinking about critical thinking. Each of them is critical of the received model, and each of them argues for one that goes beyond the conventional reduction of thinking skills to logical expertise. But each approaches the issue from a different angle, thereby providing the reader with a diversity of perspectives and accents. Re-Thinking Reason is an invaluable resource tool, research guide, and supplemental textbook, for educators across the disciplines who are concerned with incorporating thinking skills instruction in their classes.

Book Description
National Science Foundation (NSF) is a unique federal agency because it supports scientific research financially, but does not engage in scientific work itself. Its history is known only in part because the NSF is a vibrant, expanding, and living entity that makes the final telling of its story impossible. Much can be learned from its beginning as well as its component parts. If the founding of the NSF in 1950 was couched in an era of physics, especially atomic physics, certainly by the end of the 20th century and the beginning of the 21st, biology was, and remains, the queen of sciences for the predictable future. This book highlights the elite status of America’s biological sciences as they were funded, affected, and, to a very real degree, interactively guided by the NSF. It examines important events in the earlier history of the Foundation because they play strongly upon the development of the various biology directorates. Issues such as education, applied research, medical science, the National Institutes of Health, the beginnings of biotechnology, and other matters are also discussed.

Book Description
Physiology of Echinoderms is an 11-chapter book that begins by elucidating the feeding, digestion, and excretion of specific echinoderms. The critical role of amoebocytes in the excretion process involved in these organisms is also explained. This book also describes several aspects of importance to these organisms, including salinity tolerance, osmoregulation, ionic regulation, chemical composition, neural control of locomotion, biochemical affinities, toxins, and immunology. The organisms' physiology in sensory, water vascular system, respiratory system, spawning, neurosecretion, nerves, and muscles are also explained.
