This book brings the reader to the frontiers of research in some topics in superalgebras and symbolic method in invariant theory. Superalgebras are algebras containing positively-signed and negatively-signed variables. One of the book's major results is an extension of the standard basis theorem to superalgebras. This extension requires a rethinking of some basic concepts of linear algebra, such as matrices and coordinate systems, and may lead to an extension of the entire apparatus of linear algebra to ``signed'' modules. The authors also present the symbolic method for the invariant theory of symmetric and of skew-symmetric tensors. In both cases, the invariants are obtained from the symbolic representation by applying what the authors call the umbral operator. This operator can be used to systematically develop anticommutative analogs of concepts of algebraic geometry, and such results may ultimately turn out to be the main byproduct of this investigation. While it will be of special interest to mathematicians and physicists doing research in superalgebras, invariant theory, straightening algorithms, Young bitableaux, and Grassmann's calculus of extension, the book starts from basic principles and should therefore be accessible to those who have completed the standard graduate level courses in algebra and/or combinatorics.
This volume offers a new dimension to realist theories about world politics. It questions both the theoretical and empirical foundations of much of traditional realist thought by offering realist-oriented analyses that emphasize the possibilities of cooperation and accommodation through agreement over common motivations and concerns. The articles in this volume demonstrate that moral considerations can and do play a significant role in shaping state behavior and that despair about the possibility of improving the systems and institutions within which we live is unwarranted. Specific points of normative convergence are raised in some detail, especially on issues of war, membership and authority, humanitarian concern and the social consequences of globalization. Three ethical concepts form the core of the 'realism reconsidered' argued for here, namely, the ideas of pluralism, rights and fairness.
During the military stand-off between East and West known as the Cold War, each of the two camps sought out to undermine its opponent by looking for vulnerable aspects of its society. The Soviets exploited the opportunities offered to them by the pluralism that flourished in western societies. In this respect youth and student movements were a promising target. This work describes how the Soviets attempted to manipulate Student and Youth Organizations in the West, and how western governments and intelligence agencies, notably the CIA, reacted.
Effects on the Eyes and Visual System from Chemicals, Drugs, Metals and Minerals, Plants, Toxins and Venoms; also Systemic Side Effects from Eye Medications (4th Ed.)
Effects on the Eyes and Visual System from Chemicals, Drugs, Metals and Minerals, Plants, Toxins and Venoms; also Systemic Side Effects from Eye Medications (4th Ed.)
The purpose of this book is to present a synopsis of what is known about substances that have toxic properties injurious to the eyes, disturbing to vision, or affecting eyes in other unwanted ways. The coverage is truly comprehensive, encompassing local and systemic, acute and chronic, human and veterinary toxicology of the eye. The text summarizes mechanisms of injury, treatments, and other relevant knowledge for more than 3000 alphabetized substances - essentially all those on which public information is available. Also described are systemic side effects of ophthalmologic drugs, treatment of chemical burns of the eyes, and testing methods and species specificity for toxic effects on the eyes. Facilitating access to this prodigious amount of information is a large index that cross-references substances and effects, including numerous synonyms. This monumental work is a truly definitive text and a highly useful reference book that should be available to every ophthalmologist, emergency room, and medical library.
Based around the core curriculum for specialist trainees, Oxford Case Histories in Rheumatology contains over 40 well-structured, peer-reviewed cases from the Oxford Hospitals, giving detailed coverage of the specialty, including diagnostic and management dilemmas. Each case comprises a brief clinical history and the relevant examination findings; details of investigations undertaken followed by questions on differential diagnosis and management; and detailed answers and discussion. The text is complimented by over 50 radiographic illustrations and an 8-page colour plate section. The question-and-answer format is designed to enhance the reader's diagnostic ability and clinical understanding. As part of the Oxford Case Histories series, this book is aimed at post-membership trainees and consultants and will be a useful resource for those preparing for exit examinations or revalidation. It will also be of interest to those who wish to improve their skills in diagnosis and management of a broad range of rheumatological disorders.
Headache pain is unlike any other pain; when your head throbs, your entire body suffers. An estimated 20 to 40 million people in the United States are victims of chronic, recurring headaches.

With the competitive landscape changing faster than ever before, leaders understandably favor what has worked for them in the past. But that kind of approach doesn’t give anyone the motivation to develop new and better strategies to execute and navigate change. As a result, change leaders and practitioners find themselves asking the same-old questions: • With no time for failure, how can initiatives be moved forward? • How do you fit the right change method to the change objective? • How do you create a roadmap that is designed for success? • Why do some organizations succeed with change while others struggle? The authors share the insights of change management thought leaders that have stood the test of time within the scope of organization-wide change. Change managers today can review the work of these thought leaders to better understand and implement effective change in their organizations. The authors also propose a holistic meta-framework to create a path for enterprise-wide change. With the insights from case studies, you’ll learn how to create a customized and robust transformation plan for your own organizational change initiatives.
