R. B. Stein Department of Physiology, University of Alberta, Edmonton, Canada The impetus for this volume and the conference that gave rise to it was the feeling that studies on motor control had reached a turning point. In recent years, studies on motor units and muscle receptors have become increasingly detailed. Attempts to integrate these studies into quantitative models for the spinal control of posture have appeared and preliminary attempts have been made to include the most direct supraspinal pathways into these models (see for example the chapters by Nashner and Melvill Jones et al. in this volume). Thus, we felt that the time was ripe to summarize these developments in a way which might be useful not only to basic medical scientists, but also to clinicians dealing with disorders of motor control, and to bioengineers attempting to build devices to assist or replace normal control. Over the past few years, computer methods have also made possible increasingly detailed studies of mammalian locomotion, and improved physiological and pharmacological studies have appeared. There seems to be almost universal agreement now that the patterns for locomotion are generated in the spinal cord, and that they can be generated with little, if any, phasic sensory information (see chapters by Grillner and Miller et al. ). This concludes a long controversy on whether chains of reflexes or central circuits generate stepping patterns. The nature of the pattern generators in mammals remains obscure, but invertebrate studies on locomotion have recently made striking advances.

There has been a convergence in recent years of people from the physical and biological sciences and from various engineering disciplines who are interested in analyzing the electrical activity of nerve and muscle quantita tively. Various courses have been established at the graduate level or final-year undergraduate level in many universities to teach this subject matter, yet no satisfactory short text has existed. The present book is an attempt to fill this gap, and arises from my experience in teaching this material over the past fifteen years to students on both sides of the Atlantic. Although covering a wide range of biophysi cal topics from the level of single molecules to that of complex systems, I have attempted to keep the text relatively short by considering only examples of the most general interest. Problems are included whenever possible at the end of each chapter so the reader may test his understand ing of the material presented and consider other examples which have not been included in the text."

Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas. Results from these expeditions have greatly advanced our knowledge on Arctic Ocean paleoenvironments.
Published syntheses about the knowledge on Arctic Ocean geology, on the other hand, are based on data available prior to 1990. A comprehensive compilation of data on Arctic Ocean paleoenvironment and its short-and long-term variability based on the huge amount of new data including the ACEX drilling data, has not been available yet. With this book, presenting (1) detailed information on glacio-marine sedimentary processes and geological proxies used for paleoenvironmental reconstructions, and (2) detailed geological data on modern environments, Quaternary variability on different time scales as well as the long-term climate history during Mesozoic-Tertiary times, this gap in knowledge will be filled.

At a time when women could not vote and very few were involved in the world outside the home, Annie Montague Alexander (1867-1950) was an intrepid explorer, amateur naturalist, skilled markswoman, philanthropist, farmer, and founder and patron of two natural history museums at the University of California, Berkeley. Barbara R. Stein presents a luminous portrait of this remarkable woman, a pioneer who helped shape the world of science in California, yet whose name has been little known until now.
Alexander's father founded a Hawaiian sugar empire, and his great wealth afforded his adventurous daughter the opportunity to pursue her many interests. Stein portrays Alexander as a complex, intelligent, woman who--despite her frail appearance--was determined to achieve something with her life. Along with Louise Kellogg, her partner of forty years, Alexander collected thousands of animal, plant, and fossil specimens throughout western North America. Their collections serve as an invaluable record of the flora and fauna that were beginning to disappear as the West succumbed to spiraling population growth, urbanization, and agricultural development. Today at least seventeen taxa are named for Alexander, and several others honor Kellogg, who continued to make field trips after Alexander's death.
Alexander's dealings with scientists and her encouragement--and funding--of women to do field research earned her much admiration, even from those with whom she clashed. Stein's extensive use of archival material, including excerpts from correspondence and diaries, allows us to see Annie Alexander as a keen observer of human nature who loved women and believed in their capabilities. Her legacy endures in the fields of zoology and paleontology and also in the lives of women who seek to follow their own star to the fullest degree possible.

Bad Girls examines representational practices of film and television stories beginning with post-Vietnam cinema and ending with post-feminisms and contemporary public disputes over women in the military. The book explores a diverse range of popular media texts, from the Alien saga to Ally McBeal and Sex and the City, from The Net and VR5 to Sportsnight and G.I.Jane. The research is framed as a study of intergenerational tensions in portrayals of women and public institutions - in careers, governmental service, and interactions with technology. Using iconic texts and their contexts as a primary focus, this book offers a rhetorical and cultural history of the tensions between remembering and forgetting in representations of the American feminist movement between 1979 and 2005. Looking forward, the book sets an agenda for discussion of gender issues over the next twenty-five years and articulates with authority the manner in which "transgression" itself has become a site of struggle.

This 1973 book was the first comprehensive collection of techniques for culturing algae. Twenty-eight clearly written chapters by 30 outstanding algologists utilize the work of more than 600 investigators. On its initial publication, the book became a standard reference in the field.
