The world’s premier obstetrics guide–now updated with a greater focus on maternal-fetal medicine. The obstetrics text that has defined the discipline for generations of obstetrician-gynecologists is now more timely—and essential—than ever. Written by authors from the nationally known University of Texas Southwestern Medical Center, Williams Obstetrics maintains its trademark comprehensive coverage and applicability at the bedside, while offering the most current perspective of the field. This landmark text begins with fundamental discussions of reproductive anatomy and physiology. These dovetail into clinical chapters covering obstetrical complications such as preterm labor, pregnancy-related infection, hemorrhage, and hypertension, among others. Representing the culmination of a century of clinical thought, the new Twenty-Fifth Edition is enhanced by more than 1,000 full-color illustrations plus an increased emphasis on the fast-growing subspecialty of maternal-fetal medicine. Features • Entire section on the diagnosis and treatment of fetal disorders, providing deeper insights into fetal complications in utero • Traditional focus on the varied medical and surgical disorders that can complicate pregnancy • 1,000 eye-catching illustrations, including updated graphs, sonograms, MRIs, photographs, and photomicrographs • Solid evidence-based approach highlights the scientific underpinnings of clinical obstetrics, with special emphasis on physiological principles • Current professional and academic guidelines are incorporated into the text and appear in easy-to-read tables • Updated with 3,000 new literature citations through 2017. No other text can match the long-established scientific rigor and accessibility of Williams Obstetrics. With its state-of-the-art design and review of the newest advances and protocols, this not-be-missed clinical companion brings positive outcomes within reach.
This new volume in the Counterpoints series compares and contrasts different conceptions of working memory, generally recognized as the mechanism within the human cognitive system that is responsible for the temporary storage and processing of information. This notion has been used in a wide variety of ways, partly because it encapsulates several themes that have appeared in the history of research into human memory and cognition. Consequently, variations in the usage of the term working memory also arise because it is invoked by theorists with different research agendas and perspectives. The book includes contributions from proponents of different views: Robert Logie discusses the existence of three different components that control temporary verbal storage, temporary visuo-spatial storage, and the central coordination of both processing and storage, including the retrieval of information from long-term memory. Ellen Stoltzfus, Lynn Hasher, and Rose Zacks focus on the inhibitory processes that control the entrance of information into working memory and update the contents by deleting information that is no longer relevant to the task at hand. Randall Engle argues that individual differences in working memory are tantamount to differences in the attentional resources needed to retrieve information from memory, and that these lead to differences in the ability to inhibit or suppress irrelevant information. Finally, editor John Richardson identifies the key issues that have divided researchers in this field and gives an integrated account of what has been discovered about working memory. As interest in working memory is increasing at a rapid pace, an open discussion of the central issues involved is both useful and timely. This work serves this purpose for cognitive psychologists and their students.
