Summary : Research on humor is carried out in a number of areas in psychology, including the cognitive (What makes something funny?), developmental (when do we develop a sense of humor?), and social (how is humor used in social interactions?) Although there is enough interest in the area to have spawned several societies, the literature is dispersed in a number of primary journals, with little in the way of integration of the material into a book. Dr. Martin is one of the best known researchers in the area, and his research goes across subdisciplines in psychology to be of wide appeal. This is a singly authored monograph that provides in one source, a summary of information researchers might wish to know about research into the psychology of humor. The material is scholarly, but the presentation of the material is suitable for people unfamiliar with the subject-making The Psychology of Humor suitable for use for advanced undergraduate and graduate level courses on the psychology of humor-which have not had a textbook source. 2007 AATH Book Award for Humor/Laughter Research category! Up-to-date coverage of research on humor and laughter in every area of psychology Research findings are integrated into a coherent conceptual framework Includes recent brain imaging studies, evolutionary models, and animal research Draws on contributions from sociology, linguistics, neuroscience, and anthropology Provides an overview of theories of humor and early research Explores applications of humor in psychotherapy, education, and the workplace Points out interesting topics for further research and promising research methodologies Written in a scholarly yet easily accessible style 2007 AATH Book Award for Humor/Laughter Research category

Summary : This book gives emphasis to wood fiber raw materials, alternative sources of fibers for paper production, environmental issues, paper quality improvement and cost of paper production. Varieties of non-wood raw materials, including kenaf, rice straw, empty fruit bunches of palm trees, bamboo, bagasse, etc., are considered in this book. The process of fiber treatment also varied to meet paper quality improvement. Different organosolv processes of fiber treatment are discussed. Considering contemporary issues, one particular chapter analyzes the environmentally friendly way of processing non-wood fibers for paper production. The book also contains a chapter on the by-product raw materials of paper production and their profitable applications.

Summary : Rapid industrialization is a serious concern in the context of a healthy environment. With the growth in the number of industries, the waste generated is also growing exponentially. The various chemical processes operating in the manufacturing industry generate a large number of by-products, which are largely harmful and toxic pollutants and are generally discharged into the natural water bodies. Once the pollutants enter the environment, they are taken up by different life forms, and because of bio-magnification, they affect the entire food chain and have severe adverse effects on all life forms, including on human health. Although, various physico-chemical and biological approaches are available for the removal of toxic pollutants, unfortunately these are often ineffective and traditional clean up practices are inefficient. Biological approaches utilizing microorganisms (bacterial/fungi/algae), green plants or their enzymes to degrade or detoxify environmental pollutants such as endocrine disruptors, toxic metals, pesticides, dyes, petroleum hydrocarbons and phenolic compounds, offer eco- friendly approaches. Such eco-friendly approaches are often more effective than traditional practices, and are safe for both industry workers as well as environment. This book provides a comprehensive overview of various toxic environmental pollutants from a variety natural and anthropogenic sources, their toxicological effects on the environment, humans, animals and plants as well as their biodegradation and bioremediation using emerging and eco-friendly approaches (e.g. Anammox technology, advanced oxidation processes, membrane bioreactors, membrane processes, GMOs), microbial degradation (e.g. bacteria, fungi, algae), phytoremediation, biotechnology and nanobiotechnology. Offering fundamental and advanced information on environmental problems, challenges and bioremediation approaches used for the remediation of contaminated sites, it is a valuable resource for students, scientists and researchers engaged in microbiology, biotechnology and environmental sciences.

Summary : This timely book provides a thorough introduction to the inter-relationship of food and the environment. Its primary purpose is to bring to our attention the multiplicity of linkages and interconnections between what we eat and how this impacts on the earth’s resources. Having a better idea of the consequences of our food choices might encourage us to develop more sustainable practices of production and consumption in the decades ahead. Although human societies have, over time, brought under control a large proportion of the earth’s resources for the purpose of food production, we remain subject to the effective functioning of global ecosystem services. The author highlights the vital importance of these services and explains why we should be concerned about the depletion of freshwater resources, soil fertility decline and loss of biological diversity. The book also tackles some of the enormous challenges of our era: climate change – to which the agri-food system is both a major contributor and a vulnerable sector – and the prospect of significantly higher energy prices, arising from the peaking of oil and gas supplies which will reveal how dependent the food system has become upon cheap fossil fuels. Such challenges are likely to have significant implications for the long-term functioning of global supply chains and raise profound questions regarding the nutritional security of the world’s population. Taken together the book argues that a re-examination of the assumptions and practices underpinning the contemporary food system is urgently required. Environment and Food is a highly original, inter-disciplinary and accessible text that will be of interest to students and the wider public genuinely interested in and concerned by the state of the world’s food provisioning system. It is richly illustrated with figures and makes extensive use of boxes to highlight relevant examples.

Summary : This book features in-depth and thorough coverage of Minimum Impact Mill Technologies which can meet the environmental challenges of the pulp and paper industry and also discusses Mills and Fiberlines that encompass “State-of-the-Art” technology and management practices. The minimum impact mill does not mean "zero effluent", nor is it exclusive to one bleaching concept. It is a much bigger concept which means that significant progress must be made in the following areas: Water Management, Internal Chemical Management, Energy Management, Control and Discharge of Non-Process Elements and Removal of Hazardous Pollutants. At the moment, there is no bleached kraft pulp mill operating with zero effluent. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry. Sustainable pulp and paper manufacturing requires a holistic view of the manufacturing process. During the last decade, there have been revolutionary technical developments in pulping, bleaching and chemical recovery technology. These developments have made it possible to further reduce loads in effluents and airborne emissions. Thus, there has been a strong progress towards minimum impact mills in the pulp and paper industry. The minimum-impact mill is a holistic manufacturing concept that encompasses environmental management systems, compliance with environmental laws and regulations and manufacturing technologies.
