Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.

Book Description
Advances in Sheep Welfare examines the recent advances made in sheep welfare assessment, handling and management, providing state-of-the-art coverage of the welfare needs of one of the world’s most widely farmed animals. The book begins with an introduction to sheep welfare in Part One, with chapters covering biology and natural behavior, sheep production systems, and consumer and societal expectations for sheep products. Part Two goes on to highlight new advances in sheep welfare assessment, before Part Three outlines a wide range of solutions to sheep welfare challenges. The final section looks ahead to the future, considering what sheep welfare will look like in 2030 and beyond. This book is an essential part of the wider ranging series Advances in Farm Animal Welfare, with coverage of cattle, sheep, pigs and poultry. With its expert editors and international team of contributors, Advances in Sheep Welfare is a key reference tool for welfare research scientists and students, veterinarians involved in welfare assessment, and indeed anyone with a professional interest in the welfare of sheep. Brings together top researchers in the field to provide a comprehensive overview of recent advances in the understanding of sheep welfare and management Presents part of a wider series, Advances in Agricultural Animal Welfare, which provides comprehensive coverage of animal welfare of the world’s major farmed animals Highlights current advances and looks ahead to how sheep welfare management will develop in the next ten to fifteen years

Book Description
Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Book Description
Microeconomic modeling has been an important tool for agricultural economists for several decades and promises to be important for ad-dressing the research problems of the 1980s as well. This volume explores the possibilities for using micromodeling to analyze how individual farm businesses react to and are affected by farm policies. Although this purpose represents only one potential use of micro-modeling, effective modeling for policy analysis necessitates a broad look from several historical, analytical, and institutional perspectives. The Micromodeling Conference held November 18-20, 1981, at Airlie House, Virginia, under the auspices of the U.S. Department of Agri-culture's Economic Research Service and the Farm Foundation reflected these concerns.

Book Description
Researchers and policy planners are in search of a solution to address the twin challenges of maximizing agricultural production while maintaining/ improving ecosystem sustainability. Enhancing farm productivity is needed in certain regions of the world to satisfy local food consumption and farmers' needs. Linear economy-based-input intensive conventional agriculture (CAPS) has increased production output but has not made agriculture more sustainable. Henceforth, a farming system that aims to reduce the adverse impact on the environment, as well as enhance agricultural productivity by reducing environmental footprint and improving soil health and economic wellbeing is needed in the present day. Integrated organic farming systems (IOFS) involve residue recycling, bio-intensive cropping, high-tech horticulture, mushroom, dairy, poultry, fishery, apiary, etc can improve the ecosystem health and augment the income and livelihood security of the growers. Worldwide, IOFS are gaining popularity due to improved ecosystem services and improving farm productivity and livelihood security. Hence, IOFS- a circular economy-based (reuse-recycle-repair) agricultural production system can be alternatives to energy-intensive inputs based on CAPS. Hence, there is an urgent need to select suitable IOFS models with proper resource optimization for productivity maximization and better ecosystem sustainability. Undoubtedly IOFS reduces energy use from synthetic agrochemicals but food production in IOFS is highly dependent on fossil fuel energy that must be addressed urgently. Despite the enormous positive outlooks, there are several challenges in the adoption of IOFS models. The IOFS is a multiproduct-oriented production system that needs multi specialties and marketing. Capacity building and infrastructure development are also great challenges in adopting IOFS. Moreover, the development of IOFS models is highly individualistic, and location-specific production systems need proper resource optimization and characterization. Hence, the development of site-specific IOFS models to maintain food quality with productivity improvement is a genuine issue to the researchers, which needs to be addressed. Papers (original research/review/letter to the editors) spanning across the discipline related to the IOFS development in sustainable ways are encouraged for inclusion in this research topic. Papers should explicitly cover ecosystem restoration, farm productivity, and profitability and could have a specific focus on the following areas: -the IOFS models for enhancing productivity and environmental quality through an integrated management approach aiming at the maximization of use efficiencies -the management of biomass waste to restore the soil fertility, and ecosystem services the effect of integrated management practices on greenhouse gas emissions and energy use -Critical approaches for climate-smart food production systems
