This successful text is an introduction to the basic ideas and techniques of linear algebra for first- or second-year students who have a working knowledge of high school algebra (calculus is not a prerequisite). The author maintains a balance among the computational skills, theory, and applications of linear algebra--while keeping the level suitable for beginning students--and offers a multitude of examples and exercises to help students master the material. Taking a traditional approach to the subject of Linear Algebra, with some introduction for students to R^n, the Fourth Edition of Linear Algebra with Applications, newly acquired by McGraw-Hill, continues the tradition of accuracy and excellence associated with W. Keith Nicholson. Unlike the previous edition, however, the Fourth Edition introduces eigenvalues early on, in chapter 3, in a rigorous way using only matrix algebra and determinants. As well, Nicholson has added a new "bridging" chapter from Vector Geometry (Chapter 4) to the notion of an Abstract Vector Space (Chapter 6). In the traditional manner, Nicholson 4/e allows students to "hit the wall" with theory, but, with these new features, also provides students with the tools needed to overcome the wall. Synopsis This text achieves a balance among computational skills, theories and applications of linear algebra. The contents can be arranged to allow for the presentation of a traditional introduction to linear algebra or a more applied course. More than Read more...

From the use of animals in experiments to develop medicine for people to the preservation of endangered species in zoos, human beings' responsibility to and for their fellow animals has become an increasingly controversial subject. This book, which Jane Goodall in her foreword calls "unique, informative, and exciting," provides a provocative overview of the many different perspectives on the issues of animal rights and animal welfare in an easy-to-use encyclopedic format. Students, teachers, and interested readers can explore the ideas of well-known philosophers, biologists, and psychologists in this field, such as Peter Singer, Tom Regan, and over 125 others, all of whom have contributed original entries. Bekoff has provided a wide variety of well-chosen entries, defining terms and concepts and providing brief biographies, all of which relate to the topics of animal rights and animal welfare from the perspectives of many different disciplines: philosophy, psychology, ethology, anthropology, ecology, sociology, education, law, history, politics, theology, veterinary science, and public administration. The multidisciplinary approach allows users to critically examine the varied angles and arguments and gain a better understanding of the history and development of animal rights and animal protectionist movements worldwide.
