The study of electronic structure of materials is at a momentous stage, with new computational methods and advances in basic theory. Many properties of materials can be determined from the fundamental equations, and electronic structure theory is now an integral part of research in physics, chemistry, materials science and other fields. This book provides a unified exposition of the theory and methods, with emphasis on understanding each essential component. New in the second edition are recent advances in density functional theory, an introduction to Berry phases and topological insulators explained in terms of elementary band theory, and many new examples of applications. Graduate students and research scientists will find careful explanations with references to original papers, pertinent reviews, and accessible books. Each chapter includes a short list of the most relevant works and exercises that reveal salient points and challenge the reader.
This book sets out modern methods of computing properties of materials, including essential theoretical background, computational approaches, practical guidelines and instructive applications.
Attention-deficit/hyperactivity disorder (ADHD) is one of the most controversial and misunderstood medical conditions today. With skyrocketing rates of diagnosis and medication treatment, it has generated a firestorm of controversy. Alarming questions have been raised about ADHD in recent years, including: *Why are one in nine children and adolescents in the U.S. now diagnosed with ADHD, with projected rates still rising? *Why are nearly 70% of those diagnosed with ADHD prescribed medication? *What is causing the fast-rising diagnosis and medication of adults? And why are over a quarter of all college students using stimulants for academic performance? *In some southern states, why are boys over 9 years old diagnosed at rates of almost one in three? *Can we trust the stories we read and hear about ADHD, even in major media outlets? *What is driving the current ADHD explosion--is it parents, doctors, schools, culture, the healthcare system, or Big Pharma? And will it end? Stephen Hinshaw, a distinguished psychologist, and Richard Scheffler, an eminent health economist, uniquely blend clinical wisdom, current science, medical and school policy, and global trends to debunk myths and set the record straight in The ADHD Explosion. They describe the origins of ADHD and its huge costs to society; the science behind its causes as well as medication and behavioral treatment; and the variation in diagnosis and treatment across the U.S. Dealing directly with stimulants as "smart pills," they describe the epidemic of medicalization, arguing that accurate diagnosis and well-monitored care could ease the staggering economic burden linked to ADHD. In innovative ways, they unravel the many poignant issues facing children, teachers, clinicians, and family members who contend with ADHD each day. The recommendations they make can improve the quality of life for those touched by ADHD and potentially improve the productivity and safety of all society.
This data-driven book analyzes factors that will improve the efficiency and quality of the American health care delivery system through the lens of physician supply in an era of managed care. Presenting policy recommendations and a broad range of perspectives from conversations with experts in health economics, medical education, and health policy, Scheffler's work makes accessible a critical and complex area of health care.
Debunks myths and misconceptions about ADHD, and discusses the controversies surrounding skyrocketing rates of diagnosis and medication treatment as well as the condition's cost to society.
Decentralization has become a popular management strategy in many European health care systems. The term describes a wide variety of power transfer arrangements and accountability systems. The logic of decentralization is grounded in an intrinsically powerful idea; that smaller organizations, properly structured and steered, are inherently more agile and accountable than larger organizations. In a world where large organizations control wide swathes of both public and private sector activity, the possibility of establishing more locally operated, locally responsible institutions holds out great attraction. This text explores the capacity and impact of decentralization within European health care systems. It examines both the theoretical underpinnings as well as recent practical experiences, drawing upon both published literature and evidence collected directly from the field. The book also assesses the appropriateness of management processes within health systems for implementing a successful decentralization strategy. Decentralization in Health Care will appeal to health policy makers, postgraduates taking courses in health services management, HR, health policy and health economics, and human resource professionals.
This is the first book to present both classical and quantum-chemical approaches to computational methods, incorporating the many new developments in this field from the last few years. Written especially for "non"-theoretical readers in a readily comprehensible and implemental style, it includes numerous practical examples of varying degrees of difficulty. Similarly, the use of mathematical equations is reduced to a minimum, focusing only on those important for experimentalists. Backed by many extensive tables containing detailed data for direct use in the calculations, this is the ideal companion for all those wishing to improve their work in solid state research.
