Longitudinal surveys are surveys that involve collecting data from multiple subjects on multiple occasions. They are typically used for collecting data relating to social, economic, educational and health-related issues and they serve as an important tool for economists, sociologists, and other researchers. Focusing on the design, implementation and analysis of longitudinal surveys, Methodology of Longitudinal Surveys discusses the current state of the art in carrying out these surveys. The book also covers issues that arise in surveys that collect longitudinal data via retrospective methods. Aimed at researchers and practitioners analyzing data from statistical surveys the book will also be suitable as supplementary reading for graduate students of survey statistics. This book: Covers all the main stages in the design, implementation and analysis of longitudinal surveys. Reviews recent developments in the field, including the use of dependent interviewing and mixed mode data collection. Discusses the state of the art in sampling, weighting and non response adjustment. Features worked examples throughout using real data. Addresses issues arising from the collection of data via retrospective methods, as well as ethical issues, confidentiality and non-response bias. Is written by an international team of contributors consisting of some of the most respected Survey Methodology experts in the field

How to apply statistical methods to survey data–a guide to effective analysis of health surveys. With large health surveys becoming increasingly available for public use, researchers with little experience in survey methods are often faced with analyzing data from surveys to address scientific and programmatic questions. This practical book provides statistical techniques for use in survey analysis, making health surveys accessible to statisticians, biostatisticians, epidemiologists, and health researchers. The authors clearly explain the theory and methods of survey analysis along with real-world applications. They draw on their work at the National Institutes of Health as well as up-to-date information from across the literature to present: * The sampling background necessary to understand health surveys. * The application of such techniques as t-tests, linear regression, logistic regression, and survival analysis to survey data. * The use of sample weights in survey data analysis. * Dealing with complications in variance estimation in large health surveys. * Applications involving cross-sectional, longitudinal, and multiple cross-sectional surveys, and the use of surveys to perform population- based case-control analyses. * Guidance on the correct use of statistical methods found in software packages. * Extensive bibliography.

ATP-dependent active ion transport enables cells to regulate their pH value and to control their ion composition. The reverse process, transforming an ion imbalance into chemical energy, drives mitochondrial and chloroplast ATP synthesis. The mediators of these fundamental processes are ion-motive ATPases, highly conserved enzymes that play key roles in cell physiology from bacteria to man. As the first comprehensive overview of this important class of enzymes, this handbook summarizes recent knowledge about the molecular mechanism of ATPases, relating this information to the physiology and pathopyhsiology of ion transport, mitochondrial function, vesicle transport and lysosomal acidification. All important P-type, F-type and V-type ATPases are treated systematically, complemented by a special section on the cell biology and physiology of acidic compartments, and backed by an extensive bibliography and index. This premier reference source for physiologists, molecular biologists, biophysicists and clinical researchers contains contributions by the world's foremost ATPase research groups.
