Primitive Culture, Volume II: Researches Into The Development Of Mythology, Philosophy, Religion, Art, And Custom, Volume 2 - Primary Source Edition (Cambridge Library Collection - Anthropology)
by Edward Burnett TylorThe first Professor of Anthropology at the University of Oxford, Edward B. Tylor, defined the term "culture" for modern readers in this groundbreaking work. Initially published in 1871, this classic two-volume study explores the full range of learned human behavior patterns in terms of the beliefs, wisdom, laws, artistic achievements, and mores that constitute a society. The formation of anthropology as a scientific discipline began with this work, which continues to exercise a profound influence on anthropologic studies. The shared history of all humans, a common ground that evolved from primitive roots, constitutes the basis for Tylor's model of development. Drawing upon a worldwide variety of beliefs, rituals, and languages, the author illustrates an all-inclusive pattern of progress. His methods inaugurated the use of statistical data in anthropology, a standard procedure today but a landmark for his time. Volume I of Primitive Culture examines social evolution, language, and myth. The focus of this second volume is animism in society, which explores the tremendous diversity of thinking related to the concepts of the soul and religion as well as the marked similarities of spiritual beliefs.
Primordial Black Holes (Springer Series in Astrophysics and Cosmology)
by Paolo Pani Christian Byrnes Gabriele Franciolini Tomohiro Harada Misao SasakiPrimordial black holes (PBHs) were proposed more than 50 years ago as black holes possibly formed across a vast mass range in the early universe. They represent a unique probe to access the primordial universe and cosmological inflation. Furthermore, in certain mass ranges, they could comprise the entirety of the dark matter, seed supermassive black holes at high redshift, be responsible for some gravitational-wave events detected so far, and be novel gravitational-wave sources detectable with future instruments. However, detecting PBHs has proved to be extremely challenging and extensive research focused on setting a variety of constraints on the fraction of dark matter composed by these objects. This book highlights an up-to-date, comprehensive overview on this subject, including pedagogical details on the PBH formation scenarios, cosmological evolution, astrophysical implications, connections with gravitational-wave astronomy, and critical discussion of the latest and future constraints. At variance with all existing reviews on this subject, this book addresses graduate students and researchers not necessarily familiar with all areas of the topic, providing details on important key results rather than collecting and reviewing the latest literature. The topic is naturally interdisciplinary and connects areas as diverse as cosmology, particle physics, gravitational-wave astronomy, and numerical simulations. To reflect this diversity, the book includes 25 contributions from key researchers working in these different areas. It provides a unique reference both to approach the topic for the first time and to learn a specific specialized sub-area.
Primordial Prevention of Non Communicable Disease (Advances in Experimental Medicine and Biology #1121)
by Roya KelishadiThis volume provides a comprehensive overview on developmental origins of health and disease regarding various factors related to the origins of non-communicable diseases (NCDs) from early life. It offers a summary of the impacts of various factors such as epigenetics; gene-environment interaction; ethnic predisposition to NCDs and their risk factors; prenatal factors; fetal programming; maternal weight status and weight gain during pregnancy; type of feeding during infancy; growth pattern during childhood; obesity; stunting; socioeconomic status; dietary and physical activity habits; as well as environmental factors including air pollution and global climate change on the development and progress of NCDs.
Princes of Paradise (Magical Academy of Gods and Elementals #1)
by Kailin GowThe Princes of Paradise were not what they seemed... It was supposed to be Paradise...the beautiful island my mother and I moved to for her to start her new job at the luxury resort hotel, The Imperial Cutter Hotel. It was supposed to be a new start for me at the exclusive elite Academy where I received a scholarship. The beautiful location, new job, a nice new home for us, and prestigious school for me was enough to entice us to the island of Aeros. But when I met the Cutter Boys, especially Chance, who ruled the island as the son of the owner of The Imperial Cutter Hotel, and whose father started the Academy, all that changed. The most handsome and popular guys on the island, the Cutter Boys were known as the Princes of Paradise. The Cutter Boys were the most gorgeous and hottest guys I've ever met. Too bad they seem to want me gone but at the same time...can't seem to stop wanting me. ** Princes of Paradise is the first book in the M.A.G.E. Magic Academy of Gods and Elementals Series, a new adult high school bully romance fantasy series for age 18 and up. This is a reverse harem why choose romance which means there are 3 or more romantic interests for the heroine.

Principal Bundles: The Classical Case (Universitext)
by Stephen Bruce SontzThis introductory graduate level text provides a relatively quick path to a special topic in classical differential geometry: principal bundles. While the topic of principal bundles in differential geometry has become classic, even standard, material in the modern graduate mathematics curriculum, the unique approach taken in this text presents the material in a way that is intuitive for both students of mathematics and of physics. The goal of this book is to present important, modern geometric ideas in a form readily accessible to students and researchers in both the physics and mathematics communities, providing each with an understanding and appreciation of the language and ideas of the other.
Principal-Investigator-Led Missions in the Space Sciences
by National Research Council of the National AcademiesPrincipal Investigator-Led (PI-led) missions are an important element of NASA’s space science enterprise. While several NRC studies have considered aspects of PI-led missions in the course of other studies for NASA, issues facing the PI-led missions in general have not been subject to much analysis in those studies. Nevertheless, these issues are raising increasingly important questions for NASA, and it requested the NRC to explore them as they currently affect PI-led missions. Among the issues NASA asked to have examined were those concerning cost and scheduling, the selection process, relationships among PI-led team members, and opportunities for knowledge transfer to new PIs. This report provides a discussion of the evolution and current status of the PIled mission concept, the ways in which certain practices have affected its performance, and the steps that can carry it successfully into the future. The study was done in collaboration with the National Academy of Public Administration.
Principia Mathematica to *56
by Bertrand Russell Alfred North WhiteheadThe great three-volume Principia Mathematica is deservedly the most famous work ever written on the foundations of mathematics. Its aim is to deduce all the fundamental propositions of logic and mathematics from a small number of logical premisses and primitive ideas, and so to prove that mathematics is a development of logic. This abridged text of Volume I contains the material that is most relevant to an introductory study of logic and the philosophy of mathematics (more advanced students will wish to refer to the complete edition). It contains the whole of the preliminary sections (which present the authors' justification of the philosophical standpoint adopted at the outset of their work); the whole of Part 1 (in which the logical properties of propositions, propositional functions, classes and relations are established); section 6 of Part 2 (dealing with unit classes and couples); and Appendices A and B (which give further developments of the argument on the theory of deduction and truth functions).
