Download or read book The Basics of Item Response Theory Using R written by Frank B. Baker and published by Springer. This book was released on 2017-04-25 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This graduate-level textbook is a tutorial for item response theory that covers both the basics of item response theory and the use of R for preparing graphical presentation in writings about the theory. Item response theory has become one of the most powerful tools used in test construction, yet one of the barriers to learning and applying it is the considerable amount of sophisticated computational effort required to illustrate even the simplest concepts. This text provides the reader access to the basic concepts of item response theory freed of the tedious underlying calculations. It is intended for those who possess limited knowledge of educational measurement and psychometrics. Rather than presenting the full scope of item response theory, this textbook is concise and practical and presents basic concepts without becoming enmeshed in underlying mathematical and computational complexities. Clearly written text and succinct R code allow anyone familiar with statistical concepts to explore and apply item response theory in a practical way. In addition to students of educational measurement, this text will be valuable to measurement specialists working in testing programs at any level and who need an understanding of item response theory in order to evaluate its potential in their settings.

Download or read book Coastal Marine Ecosystems of Latin America written by U. Seeliger and published by Springer Science & Business Media. This book was released on 2000-10-18 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

Download or read book Marine Mammals Fisheries Tourism and Management Issues written by Nicholas Gales and published by CSIRO PUBLISHING. This book was released on 2003-10-22 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Mammals: Fisheries, Tourism and Management Issues brings together contributions from 68 leading scientists from 12 countries to provide a comprehensive, up-to-date review on the way we manage our interactions with whales, dolphins, seals and dugongs. The book examines how we have fared conserving the world’s marine mammal populations, with a focus on the key issues of fisheries and tourism. From a unique southern hemisphere perspective, the authors consider how science informs the culling debate, how wild fisheries and aquaculture interact with marine mammal populations and how we might manage the effects of whale, dolphin and seal watching industries. The authors also address other issues such as the way in which ethics, genetics, acoustics, ecosystem models and pollution influence the management and conservation of marine mammals. Marine Mammals is an invaluable and accessible resource for all those involved with marine mammals, including scientists, managers, policy makers, industry representatives and students. Winner of a 2004 Whitley Award.

Book excerpt: Obesity: Oxidative Stress and Dietary Antioxidants cover the science of oxidative stress in obesity and associated conditions, including metabolic syndrome, bariatric surgery, and the potentially therapeutic usage of natural antioxidants in the diet or food matrix. The processes within the science of oxidative stress are not described in isolation, but in concert with other processes, such as apoptosis, cell signaling and receptor mediated responses. This approach recognizes that diseases are often multifactorial and oxidative stress is but a single component. The book is designed for nutritionists, dietitians, food scientists, physicians and clinical workers, health care workers and research scientists. - Covers the basic processes of oxidative stress, from molecular biology, to whole organs - Highlights antioxidants in foods, including plants and other components of diet - Provides the framework for further, in-depth analysis or studies via well-designed clinical trials or via the analysis of pathways, mechanisms and componentsa
Download or read book Wikipedia U written by Thomas Leitch and published by JHU Press. This book was released on 2014-11-01 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores the battle between the top-down authority traditionally ascribed to experts and scholars and the bottom-up authority exemplified by Wikipedia. Since its launch in 2001, Wikipedia has been a lightning rod for debates about knowledge and traditional authority. It has come under particular scrutiny from publishers of print encyclopedias and college professors, who are skeptical about whether a crowd-sourced encyclopedia—in which most entries are subject to potentially endless reviewing and editing by anonymous collaborators whose credentials cannot be established—can ever truly be accurate or authoritative. In Wikipedia U, Thomas Leitch argues that the assumptions these critics make about accuracy and authority are themselves open to debate. After all, academics are expected both to consult the latest research and to return to the earliest sources in their field, each of which has its own authority. And when teachers encourage students to master information so that they can question it independently, their ultimate goal is to create a new generation of thinkers and makers whose authority will ultimately supplant their own. Wikipedia U offers vital new lessons about the nature of authority and the opportunities and challenges of Web 2.0. Leitch regards Wikipedia as an ideal instrument for probing the central assumptions behind liberal education, making it more than merely, as one of its severest critics has charged, “the encyclopedia game, played online.”
