This book presents modern methods and real-world applications of compositional data analysis. It covers a wide variety of topics, ranging from an updated presentation of basic concepts and ideas in compositional data analysis to recent advances in the context of complex data structures. Further, it illustrates real-world applications in numerous scientific disciplines and includes references to the latest software solutions available for compositional data analysis, thus providing a valuable and up-to-date guide for researchers and practitioners working with compositional data. Featuring selected contributions by leading experts in the field, the book is dedicated to Vera Pawlowsky-Glahn on the occasion of her 70th birthday.
It is difficult to imagine that the statistical analysis of compositional data has been a major issue of concern for more than 100 years. It is even more difficult to realize that so many statisticians and users of statistics are unaware of the particular problems affecting compositional data, as well as their solutions. The issue of ``spurious correlation'', as the situation was phrased by Karl Pearson back in 1897, affects all data that measures parts of some whole, such as percentages, proportions, ppm and ppb. Such measurements are present in all fields of science, ranging from geology, biology, environmental sciences, forensic sciences, medicine and hydrology. This book presents the his...
This book critically explores pedagogical activities, policies, and coursework that teacher education programs can provide to more fully prepare teacher candidates and in-service educators for professional practice in urban schools. It illustrates how teacher educators from across the United States are supporting teacher candidates and in-service teachers to possess the knowledge, skills, and dispositions for equity-oriented instructional practices and advocacy for professional engagement in the urban context. Chapters share insider perspectives of urban teacher education on preparing teachers to teach in culturally, linguistically, and socio-economically diverse classrooms. They discuss tea...
Numerous reports demonstrate that the reproductive system could be affected by multiple potential toxicological agents. The volume includes different aspects of the development of new approaches to in vitro testing using sperm cells and systems involved on reproduction in mammals. Comparative analysis of in vivo and in vitro methods has been included to take steps towards the further development of and applications of new systems for germline toxicology.
This book is the first in a series of planned volumes focused on preserving the character of the development of bioethics in particular cultural contexts. As the first of these volumes, Leo Pessini, Christian de Paul de Barchifontaine, and Fernando Lolas Stepke’s work has succeeded well. It has brought together accounts by sch- ars who were crucial to the emergence of bioethics in the Ibero-American cultural domain. This trail-blazing work in the history of bioethics will be of enduring s- nificance. I am deeply in their debt for having shouldered this far from easy task. Bioethics is the product of very particular socio-historical developments. Most prominent among them have been (1) the ...
Latent knowledge in the field of pig reproduction is vast but scattered, making it difficult to take in all information at a glance. Moreover, nascent branches in biotechnology cannot grow if deprived of roots. The book Boar Reproduction: Fundamentals and New Biotechnological Trends links the past, the present and the emerging scientific research fields on reproductive biotechnology, offering a rigorous but easy to follow compilation of topics, from “old favorites” to the latest advances. The book is organized in three parts. The chapters of the first and second part cover various biological aspects of boar spermatozoa within the male, and within the female environments, respectively. The most common laboratory and artificial insemination techniques are discussed in the third part. As an additional feature, some chapters focus on the basis of a technology transfer to bring research expertise from basic science to the market, making the information provided in this book suitable for academic, research and other professional applications.
This book presents a series of perspectives showing the current knowledge about human evolution. On the occasion of the 150th anniversary of Darwin's book, The Descent of Man, and Selection in Relation to Sex, in which he explicitly addresses the natural origin of the human species, this collective work reviews current and diverse aspects of human evolution: from psychology, linguistics, genomics, paleontology, artistic expression or sexual selection. It also offers a historical, social and ideological context of what is often considered to be Darwin's second great work after The Origin of Species. Although current research is concentrated largely on fossils and genomes, this book also deals...
