This thesis describes a search for the rare decay KL → ?0?0? using data from the KTeV experiment, using the topology KL → ?0?$0top{D}$? (where ?$0top{D}$ → ?e+e-). Due to Bose statistics and the real nature of the photon, the KL → ?0?0? decay can proceed at lowest order only by the Cp conserving direct emission of an E2 photon. The decay vanishes to O(p4) in chiral perturbation theory and is a probe of the theory to the sixth order. The primary background to this decay consists of KL → ?0?$0top{D}$ events with one lost photon. The upper limit for the decay KL ?0?0? presented in this thesis is 2.32 x 10-7 at the 90% confidence level. This upper limit was derived from both 1997 and 1999 data, using a blind analysis. The upper limit was derived from a Feldman-Cousins method, based on a weighted total of 0.53 data events in the signal region with an expected KL → ?0?0?$0top{D}$ background of 0.37 ± 0.28 events. The previous upper limit for this decay was 5.6 x 10-6 at the 90% confidence level.

The Problem Solvers are an exceptional series of books that are thorough, unusually well-organized, and structured in such a way that they can be used with any text. No other series of study and solution guides has come close to the Problem Solvers in usefulness, quality, and effectiveness. Educators consider the Problem Solvers the most effective series of study aids on the market. Students regard them as most helpful for their school work and studies. With these books, students do not merely memorize the subject matter, they really get to understand it. Each Problem Solver is over 1,000 pages, yet each saves hours of time in studying and finding solutions to problems. These solutions are worked out in step-by-step detail, thoroughly and clearly. Each book is fully indexed for locating specific problems rapidly. For students taking basic and advanced psychology courses. Each chapter provides comprehensive explanations and solutions to problems, and ends with a series of short questions and answers to help in preparation for exams. Also included is a particularly helpful guide to writing experimental reports.

Their music blazed a trail across the world but Led Zeppelin's media silence was as deafening as their live shows. Throughout their extraordinary career the band were untouchables, refusing interviews and treating press attention with disdain. Few journalists were allowed to enter the house of the holy, even when Led Zeplin ll knocked Abbey Road from number 1 and Stairway To Heaven became the most requested radio track of all time. Yet one writer did penetrate their inner sanctum. Ritchie Yorke has eaten, slept and breathed Led Zeppelin for the length of his distinguished career, touring with them and regularly granted an audience with the band. The result is Led Zeppelin - From the early days to Page and Plant. Originally published as The Led Zeppelin Biography in 1975, and frequently updated, it's a definitive rock work which is the most detailed study ever of a group who remained a closed book to every other writer. Over two decades and 50 million album sales since it first appeared, this famous account of Led Zeppelin's odyssey is updated to cover the death of infamous manager Peter Grant and the successful musical reunion of Jimmy Page and Robert Plant. Led Zeppelin - From the early days to Page and Plant is the stuff of rock legend.

Based on the work of Piaget and Neo-Piagetians, and exploring other major models in development, this multidisciplinary book sets forth a new model of development from a causal perspective. The text geared to multiple levels and multiple audiences.

The Signature Edition of Manly P. Hall’s Esoteric Classics on America Fully reset and newly introduced by PEN Award-winning historian Mitch Horowitz, The Secret Destiny of America (1944) and America’s Assignment with Destiny (1951) are Manly P. Hall’s core statements on the esoteric purpose and occult backstory of the United States. In these two volumes appears Hall’s thrilling thesis that democracy and personal liberty are part of a “Great Plan” extending from the pharaonic era to Hellenic secret societies to illumined intellects such as Francis Bacon and Christopher Columbus to modern expressions of Rosicrucianism and Freemasonry, finally blossoming among the ideals of America’s Founders. In his introduction, Mitch explores the historicism of Hall’s writing on America, highlighting lasting points and augmenting the record where new information is available. Mitch specifically considers the Atlantean thesis from the perspective of the twenty-first century; reviews Hall’s career-long influence on President Ronald Reagan; examines the eye-and-pyramid of the Great Seal of the United States; contextualizes the impact of Freemasonry on the nation’s founding; explores Mesoamerican civilization and its complexities; and critically considers the role of secret societies in modern life. “Hall ranks among the few historical writers who at least recognized the inceptive role of Freemasonry in America’s founding,” Mitch writes, “a perspective only recently granted overdue treatment in scholarly literature.” Indeed, it was Manly P. Hall alone who kept alive the light of esoteric ideas—and their role in the nation’s formation—during the time he produced these seminal volumes. They are presented here, with a substantial historical introduction, in their definitive form.

The field of human development focuses on the growth and development of the human being including physical, social, psychological, and emotional development. Under the broad umbrella of the term human development you find countless topics that range from charting the emotional attachment of an infant to his or her parents and its long-term effects on well-being, media violence and adolescents′ behavior, or factors moderating the natural decline in physical and mental abilities associated with aging. The Encyclopedia of Human Development is the first comprehensive, authoritative, and informative reference work that presents state-of-the-art research and ready-to-use facts from the fields of psychology, individual and family studies, and education in a way that is not too technical. With more than 600 entries, this three-volume Encyclopedia covers topics as diverse as adolescence, cognitive development, education, family, gender differences, identity, longitudinal research, personality development, prenatal development, temperament, and more. Key Features Provides cross-disciplinary coverage, with contributions from experts in the fields of psychology, education, human development and family studies, and gerontology Highlights classic studies and theories and provides brief biographies of notable researchers and theorists Takes a lifespan approach by including several "anchor essays" that cover specific phases of development such as prenatal, infancy, childhood, adolescence, early and middle adulthood, later adulthood and aging Begins with an Introduction that details the scope, rationale, and audience for the work The cross-disciplinary field of human development is one that captures interest among and holds practical relevance for the general public as well as academia, therefore this engaging Encyclopedia will be a welcome addition to any academic or public library.
