This book addresses herbicides and their use as an important aspect of modern weed management,and strives to place them in an ecological framework. Many... weed scientists believe agriculture is a continuing struggle with weeds - without good weed control, good and profitable agriculture is impossible. Each agricultural discipline sees itself as central to agriculture's success and continued progress, and weed science is no exception. While notdenying the importance of weed management to successful agriculture, this book places it in alarger ecological context. The roles of culture, economics, and politics in weed management are also discussed, enabeling scientists and students to understand the larger effects on society. NEW TO THIS EDITION: * Information on New herbicides included, along with the old herbicides that are important for understanding the history * New section on weed resistance to herbicides and genetic engineering * New information on invasive plants * Expanded chapters on Biological Control, Pesticide Legislation and Regulation, Weed Management Systems, and more

The past decade has seen many advances in physical layer wireless communication theory and their implementation in wireless systems. This textbook takes... a unified view of the fundamentals of wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in probability and digital communication. Topics covered include MIMO (multi-input, multi-output) communication, space-time coding, opportunistic communication, OFDM and CDMA. The concepts are illustrated using many examples from real wireless systems such as GSM, IS-95 (CDMA), IS-856 (1 x EV-DO), Flash OFDM and UWB (ultra-wideband). Particular emphasis is placed on the interplay between concepts and their implementation in real systems. An abundant supply of exercises and figures reinforce the material in the text. This book is intended for use on graduate courses in electrical and computer engineering and will also be of great interest to practising engineers.

I honestly feel that every incoming student nurse should have a copy of the Fundamentals Success book because it familiarizes students with what their fundamental tests will be like. Who wouldn't benefit from knowing what their test is going to look like? Being prepared with Fundamentals Success meant I hit the ground running. I aced my first test when most of my classmates were facing their first ever academic failures. Nursing school is nothing like anything I have ever done before, memorizing text books will do little to prepare you to be a critical thinker. To succeed you must be able to apply the knowledge in multi-step process...the nursing process! The FA Davis books take you there and they do it quickly, because we nursing students needed to know it yesterday! - Corrie Cyre, Hillsborough Community College Southshore Student Nurses Association President Click Here for a Special Mail-In Rebate Offer

This eighth edition of McCall's well-respected book continues to present concepts in a way that students can easily understand. The new edition has been... updated throughout and now includes recommendations by the APA Task Force on Statistical Inference. As in previous editions, McCall helps students see the many real applications of statistics to research in the behavioral sciences. Taking a traditional approach to teaching the basic statistical concepts and methods used in behavioral research. McCall emphasizes building an understanding of the logic of statistics rather than stressing the mechanics. In this exciting revision, McCall continues to keep the data for the computational problems simple, so your students can focus on the rationale and outcome of techniques rather on the calculations themselves. Using clear discussion, a wide variety of end-of-chapter exercises, and examples drawn from actual studies, McCall helps students learn how to choose appropriate statistical methods and correctly interpret the results. Also retained in this edition are the author's step-by-step explanations for each proof and his clear definitions of symbols-the essential vocabulary of statistics-that have been so successful in helping students master the material.

David Howell's practical approach focuses on the context of statistics in behavioral research, with an emphasis on looking before leaping; investigating... the data before jumping into a test. This provides you with an understanding of the logic behind the statistics: why and how certain methods are used rather than just doing techniques by rote. Learn faster and understand more because Howell's texts moves you beyond number crunching, allowing you to discover the meaning of statistical results and how they relate to the research questions being asked.
