Available in PDF, EPUB and Kindle. Book excerpt: Malnutrition caused by deficiencies of vitamins and minerals - also called hidden hunger - impairs both the intellectual and physical development of a child. Due to the absence of clinical symptoms and assessments, no intervention can be staged. The tragedy is that this, in turn, decreases the child’s chance to escape from poverty. This book looks at malnutrition in high-income countries, the nutrition transition and nutritional deficiencies in low-income countries, consequences of hidden hunger, and interventions to improve nutrition security. Written by leading experts in the field, it clearly stresses that national governments and international organizations must make malnutrition one of their top priorities in order to provide children with optimal conditions for a healthy future.

Download or read book Contributions to Statistical Analysis written by Rafael Hernandez-Nieto and published by Createspace Independent Pub. This book was released on 2002-07 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, two new coefficients have been proposed: the Coefficient of Proportional Variance (Cpv) and the Coefficient of Content Validity (Ccv). The Coefficient of Proportional Variance proposes a solution to the problem of measuring and evaluating the relative variability of a given distribution, obviating the problems of subjective interpretation and value judgments. The mathematical relationship derived from the Cpv allows for a more precise and more scientific interpretation of relative variability of data. The Coefficient of Content Validity permits the calculation of the content validity for each item, as well as the total content validity, of any data collection instrument that has been subjected to the evaluation of several judges (Panel of Experts Technique). Until now, according to the psychometric and statistical literature, a quantitative estimator of the content validity of a measuring instrument had not been achieved.
