Stimulated by the concern for environmental problems that arose during the 1970s and 1980s, related both to global and national questions of sustain ability, the German government committed itself to advancing ecosystem research as a central component of planning for environment ally, economically, and socially sound policies and for resource manage ment during the 21 st century. Ecosystem research has been promoted at institutions spread throughout the country and that are favorably struc tured to conduct interdisciplinary studies. Research funding is derived from both the federal union and state governments. Results from the research programme at several of these institutions are summarized in this volume: 1. to provide a status report on process understanding within ecosystem types that are viewed as building blocks of complex, highly-modified Central European landscapes, 2. to document progress at institutions pursuing ecosystem science and promoting interdisciplinary approaches, 3. to support the next steps in generalizing the research results, e. g., to obtain a picture of ecosystem function in time and space or oflandscape function, and 4. to examine how the results may be applied to better manage natural resources and achieve sustainability.

The study of the relationship between the structure, morphology and properties of polymer films has significantly progressed in recent years through the use of a number of phyiscal techniques - some new and some old. These methods include small and large angle x-ray diffraction, bire fringence, light scattering, infrared dichroism, fluorescence polarization, light and electron microscopy and interferrometry. This collection of papers, most of which were presented at a symposium at the Boston American Chemical Society Meeting in April, 1972, represent a collection of recent studies using many of these methods by some of the leading scientists in their fields. It is evident that these various techniques permit the study of various aspects of film structure such as crystal structure and orientation, amorphous orientation, the interrelation of crystalline and amorphous regions in lamellar, fibrillar, and spherulitic superstructure and the relationshi. p of these structural variables to the mechanical and optical properties of the films. Film structure is sufficiently complex that a complete understanding of the relationship between structure and properties will come from the employment of a combination of several of these methods. vii CONTENTS Optical Studies of the Morphology of Polymer Films *** * * 1 Richard S.

This highly popular resource - written in an easy-to-read style and format - delivers everything nurses and other health researchers need to know about designing, testing, selecting, and evaluating instruments and methods for measurement in nursing. The Fifth Edition features the most current content, strategies, and procedures available with direct applicability to nurses and health researchers engaging in interprofessional research, collaboration, education, and evidence-based practice. Five new chapters focus on challenges to using big data, evaluation and measurement in interprofessional practice and education, metrics and benchmarking in health professions education and practice, and measurement issues in translational science. The book gives particular attention to measurement issues resulting from changes in nursing, health research, and the increased emphasis on and undertaking of interprofessional research and evaluation. Presenting the material in step-by-step format, the book is designed for readers with little or no experience in measurement, statistics, or interprofessional issues. It focuses on increasing the reader's ability to use measures that are operationalized within the context of theories and conceptual frameworks, derived from sound measurement principles and practices and adequately tested for reliability and validity. Additionally, the text provides a pragmatic account of the processes involved in all aspects of measurement. Studies conducted by nurses and researchers in varied settings illustrate the measurement processes. New to the Fifth Edition: Thoroughly updated and revised Delivers new and emerging strategies Reflects recent changes to nursing, health research, and emphasis on interprofessional research Includes five completely new chapters addressing challenges to using big data, evaluation and measurement in interprofessional practice and education, metrics and benchmarking in health professions education and practice, and measurement issues in translational science Key Features: Easy-to-read content and format Assumes no prior knowledge of measurement, statistics, or interprofessional issues Provides studies conducted by nurses and researchers in varied settings Offers a pragmatic account of the processes involved inn all aspects of measurement
