| mg 1980: Handbook of Distance Education Michael Grahame Moore, 2013-05-07 The third edition of this award-winning Handbook continues the mission of its predecessors: to provide a comprehensive compendium of research in all aspects of distance education, arguably the most significant development in education over the past three decades. While the book deals with education that uses technology, the focus is on teaching and learning and how its management can be facilitated through technology. Key features include: Comprehensive coverage that includes all aspects of distance education, including design, instruction, management, policy, and a section on different audiences. Chapter authors frame their topic in terms of empirical research (past and present) and discuss the nature of current practice in terms of that research. Future research needs are discussed in relation to both confirmed practice and recent changes in the field. Section one provides a unique review of the theories that support distance education pedagogy. Section six includes a unique review of distance education as a component of global culture. This book will be of interest to anyone engaged in distance education at any level. It is also appropriate for corporate and government trainers and for administrators and policy makers in all these environments. Recipient of the 2013 IAP Distance Education Book Award |

ZIEGLER Growth, development and reproductive success of individual plants depend on the interaction, within tolerance limits, of the factors in the physical, chemical and biological environment. The first two volumes of this series addressed fea tures of the physical environment (Vol. 12A) and the special responses of land plants as they relate to water use and carbon dioxide assimilation (Vol. 12B). In this volume we consider specific aspects of the chemical and biological envi ronment, and whereas the previous volumes were primarily concerned with the atmospheric interactions, our emphasis here shifts very much to the soil. This complex medium for plant growth was briefly reviewed in Chapter 17, Volume 12A. Since it is difficult to determine the precise physical and chemical interactions in the soil, it is even more difficult to determine the important biological interactions among organisms. Nevertheless there is growing aware ness of the significance of these interactions and their effects on physiological processes in the individual plant. |

| mg 1980: Warmed-Over Flavor of Meat Allen J. St. Angelo, 2012-12-02 Warmed-Over Flavor of Meat discusses related problems and issues on warmed-over flavor (WOF) of meat that contributes to a decrease in sale, meat consumption, and production expansion. WOF is old, stale, rancid, and painty flavor and odor of meat, apparently caused by the catalytic oxidation of unsaturated fatty acids. Comprised of 10 chapters, the book initially describes the mechanisms of metals' role in the promotion of lipid oxidation. The text also discusses the content and distribution of iron in meat and the evidence concerning the ability of the various forms of iron in meat to promote oxidative degradation of lipids. The subsequent chapters describe the oxidative deterioration in muscle foods and the free radical processes pertinent to autoxidation of foods. A chapter presents evidence for and against heme catalysis of lipid oxidation and the antioxidant role of nitrite in cured meats. The book also considers sensory and instrumental analysis of volatiles and undesirable flavors related to WOF and the isolation and separation of heteroatomic compounds associated with beef flavor. The remaining chapters describe several methodologies for retarding or preventing WOF in meat, focusing on the practical procedure of the Maillard reaction. Lastly, sources of natural antioxidants for meat product preservation are considered. Food scientists, researchers, and manufacturers will find this book invaluable. |

| mg 1980: Cardiovascular Disease in the Elderly Franz H. Messerli, 2012-12-06 That geriatric cardiology has become a science and clinical discipline in its own rights is beyond dispute. Most cardiac disorders present with different symptoms and signs, require a different diagnostic and therapeutic approach, and also have a different prognosis in the elderly as compared to younger patients. Cardiovascular Disease in the Elderly provides a comprehensive, up-to-date guide to the physician, representing a pioneering work in this increasingly complex area. For this third edition most of the chapters have been completely rewritten, some by different authors. Four new chapters have been added, dealing with cardiac transplantation, invasive cardiovascular procedures, dietary considerations and ethical considerations. It cannot be denied that invasive procedures and transplantation are highly controversial in this area, and the ethical dilemmas involved are ably discussed by Dr Davis and associates. All chapters are supplied with a thorough list of references, making this third edition of Cardiovascular Disease in the Elderly the most thorough, concise guide for the practicing physician. |
| mg 1980: Vitamin C S. Nobile, J.H. Woodhill, 2012-12-06 Parents and ancestors are always important: they endow us with a genetic inheritance for better or for worse, for the balanced diet, for overfeeding or for starvation. Some of us die young, some succumb in middle age to chronic disease, others join the gero cracy - the healthy, happy people in their 70s, 80s or even 90s. Genetic inheritance, nurture and nutrition, all play their part. The nurture and nutrition are our own responsibility; we make our choices and live with the consequences. This book is dedicated to the students of nutrition who may be interested in the subject for themselves alone, for their families, for teaching and counselling others and for research and investi gations. We found it necessary to include basic information in order to support some of the statements we make or advice we give; this material appears either in the main body of the text or as footnotes. If the student of nutrition is familiar with the basic con cepts, these sections can be skipped. At the end of the book we have included appendices, with examples of daily menus pro viding adequate vitamin C, an extensive bibliography, a glossary and an index. We have drawn up a food table of the vitamin C content of specific foods and described the point-system which is a ready-reckoner for approximate calculation of the vitamin C content of foods and diets. |
| mg 1980: The Arctic Seas Yvonne Herman, 2012-12-06 The Arctic region has long held a fascination for explorers and scientists of many countries. Despite the numerous voyages of exploration, the na ture of the central Arctic was unknown only 90 years ago; it was believed to be a shallow sea dotted with islands. During Nansen's historic voyage on the polarship Fram, which commenced in 1893, the great depth of the central basin was discovered. In the Soviet Union, investigation of the Arctic Ocean became national policy after 1917. Today research at several scientific institutions there is devoted primarily to the study of the North Polar Ocean and seas. The systematic exploration of the Arctic by the United States com menced in 1951. Research has been conducted year-round from drifting ice islands, which are tabular fragments of glacier ice that break away from ice shelves. Most frequently, ice islands originate off the northern coast of Ellesmere Island. These research platforms are occupied as weather sta tions, as well as for oceanographic and geophysical studies. Several inter national projects, conducted by Canadian, European, and U. S. groups, have been underway during the last three decades. Although much new data have accumulated since the publication of the Marine Geology and Oceanography of the Arctic Seas volume in 1974 (Yvonne Herman, ed. ), in various fields of polar research-including present-day ice cover, hydrogra phy, fauna, flora, and geology-many questions remain to be answered. |

Other papers on neuroendocrinology, mechanism of hormone action, reproductive biology, subcellular processing of hormones and their receptors, hereditary resistance to 1,25-dihydroxyvitamin D are also encompassed. Physiologists, endocrinologists, biochemists, and scientists involved in hormone research will prove the book invaluable. |
| mg 1980: The Politics of Governance Lucy Koechlin, Till Förster, 2014-11-13 How do government arrangements emerge? When and how does individual agency turn into collective agency? How do sensory experiences of violence, instability, etc affect the configuration of governance arrangements? When, why, and how are governance arrangements institutionalized? This book seeks to contribute to a non-normative conceptualization of the emergence and transformation of government arrangements, and addresses the under-theorization of actors and agency in conventional governance theories. The editors and contributors theorize the concept of governance more concretely by analyzing the key actors and arrangements that define states of governance across different places and by examining its performance and development in particular settings and time periods. Each contribution to the edited volume is based on a case-study drawn from Africa, though the book argues that the core issues identified remain the same across the world, though in different empirical contexts. The contributions also range across key disciplines, from anthropology to sociology to political science. This ground-breaking volume addresses governance arrangements, discusses how social actors form such arrangements, and concludes by synthesizing an actor-centered understanding of political articulation to a general theory of governance. Scholars across disciplines such as political science, development studies, African studies, and sociology will find the book insightful. |

Valenty, 2001-08-30 Feldman, Valenty, and their contributors present state-of-the-art evaluations of linkages between personality, motivation, decision making, leadership style, and behavior among political leaders across divergent cultures. Leading scholars in the field examine the application of theoretical approaches and research methods used to evaluate these important relationships. They effectively illustrate the concomitant role of cultural and political context, historical circumstance, environmental factors, and socialization agents affecting political leadership and performance. Contributors evaluate methods currently in use by scholars in political science, psychology, political psychology, social psychology, and history, including psychodiagnostic and psychobiographical approaches, and the application of these methods in profiling the personalities of political leaders. Each chapter presents a unique case study evaluating a political leader or leaders including such major figures as Mao Zedong, Tony Blair, Seyyed Mohammed Khatami, Helmut Kohl, and Stalin, Yeltsin, and Putin. |

| mg 1980: Rethinking Bridge Deck Longevity and Maintenance with Portland Cement Polymer Concrete Andrew P. Agosto, 2008 Bridge deck deterioration in the northern Midwest creates significant costs to state Departments of Transportation (DOT's) in the region. The fundamental cause of the problem is low tensile strength and water permeable reinforced concrete resulting in deck cracking and ultimately reinforcing bar corrosion. Portland Cement Polymer Concrete (PCPC) combined with a design approach tailored to its advantages could virtually eliminate early deck deterioration and the associated costs providing an alternative asset management path for bridge decks. Bridge decks would no longer have to be removed from their substructure every fifteen years and replaced. The results would be higher quality, longer lasting bridge decks with lower life cycle costs. This project will demonstrate the feasibility and methodology of such a strategy. This project will develop a strategy that combines innovative concrete materials, novel design and cost analysis that enhances the longevity and reduces the life cycle cost of highway bridge decks. The project is expected to show significant life-cycle cost advantages to using a high performance bridge deck material. |

Office of Water Regulations and Standards, 1986 Section 304(a) (1) of the Clean Water Act 33 U.S.C. 1314(a) (1) requires the Environmental Protection Agency (EPA) to publish and periodically update ambient water quality criteria. These criteria are to accurately reflect the latest scientific knowledge (a) on the kind and extent of all identifiable effects on health and welfare including, but not limited to, plankton, fish shellfish, wildlife, plant life, shorelines, beaches, aesthetics, and recreation which may be expected from the presence of pollutants in any body of water including ground water; (b) on the concentration and dispersal of pollutants, or their byproducts, through biological, physical, and chemical processes; and (c) on the effects of pollutants on biological community diversity, productivity, and stability, including information on the factors affecting rates of eutrophication and organic and inorganic sedimentation for varying types of receiving waters. In a continuing effort to provide those who use EPA's water quality and human health criteria with up-to-date criteria values and associated information, the document was assembled. The document includes summaries of all the contaminants for which EPA has developed criteria recommendations. |

| mg 1980: Water Requirements for Irrigation and the Environment Marinus G. Bos, R. A. L. Kselik, Richard G. Allen, David Molden, 2008-11-23 Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than consumed by the crop. The non-consumed fraction of the water may cause a variety of undesirable effects ranging from water-logging and salinity within the irrigated area to downstram water pollution. This book discusses all components of the water balance of an irrigated area; evapotranspiration (Ch.2), effective precipitation (Ch.3) and capillary rise from the groundwater table (Ch.4). Chapter 5 then combines all components into a water management strategy that balances actual evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area (for a substainable environment). Chapter 6 presents CRIWAR 3.0, a simulation program that combines all water balance components into a single simulation procedure. The chapter describes the use of the CRIWAR software for developing water requirement tables and other useful information based on the selected water management strategy. This version greatly expands upon the capabilities of previously published programs. |
