Altered Traits: Science Reveals How Meditation Changes Your Mind, Brain And Body
by Daniel Goleman Richard DavidsonTwo New York Times–bestselling authors unveil new research showing what meditation can really do for the brain. In the last twenty years, meditation and mindfulness have gone from being kind of cool to becoming an omnipresent Band-Aid for fixing everything from your weight to your relationship to your achievement level. Unveiling here the kind of cutting-edge research that has made them giants in their fields, Daniel Goleman and Richard Davidson show us the truth about what meditation can really do for us, as well as exactly how to get the most out of it. Sweeping away common misconceptions and neuromythology to open readers’ eyes to the ways data has been distorted to sell mind-training methods, the authors demonstrate that beyond the pleasant states mental exercises can produce, the real payoffs are the lasting personality traits that can result. But short daily doses will not get us to the highest level of lasting positive change—even if we continue for years—without specific additions. More than sheer hours, we need smart practice, including crucial ingredients such as targeted feedback from a master teacher and a more spacious, less attached view of the self, all of which are missing in widespread versions of mind training. The authors also reveal the latest data from Davidson’s own lab that point to a new methodology for developing a broader array of mind-training methods with larger implications for how we can derive the greatest benefits from the practice. Exciting, compelling, and grounded in new research, this is one of those rare books that has the power to change us at the deepest level.

Alternative Agricultural and Food Policies and the 1985 Farm Bill (Routledge Revivals)
by Gordon C. Rausser and Kenneth R. FarrellIn 1985, the U.S. Congress confronted the difficult and complex task of developing a 5-year omnibus legislation allowing for lower commodity prices. But, policies predicated on the concept of agriculture as a unique sector of the economy became less and less appropriate to the highly interdependent, open agricultural economy throughout the 1980s. First published in 1985, this collection of 16 papers and related discussions contained in these proceedings is an important contribution toward understanding the issues, options, and dilemmas in U.S. agricultural policy. This is an ideal title for students interested in environmental studies, agriculture, and national policy.
Alternative Arrangements for Marine Fisheries: An Overview (Routledge Revivals)
by Francis T. Christy, Jr.The maintenance of the freedom of fishing in the face of the changing circumstances that were occurring at the time of this title’s original publication in 1973 had produced several damaging consequences. It had led to considerable waste, in both biological and economic terms, and had been the source of increasing conflict. This waste can only be prevented by the adoption of management measures and by the removal of the condition of free and open access. This book explores various techniques for this, and will be of interest to students of environmental management.
Alternative Development: Unravelling Marginalization, Voicing Change
by Piers Blaikie Cathrine BrunThis book brings together a collection of essays that discuss alternative development and its relevance for local/global processes of marginalization and change in the Global South. Alternative development questions who the producers of development knowledges and practices are, and aims at decentring development and geographical knowledge from the Anglo-American centre and the Global North. It involves resistance to dominant political-economic processes in order to further the possibilities for non-exploitative and just forms of development. By discussing how to unravel marginalization and voice change through alternative methods, actors and concepts, the book provides useful guidance on understanding the relationship between theory and practice. The main strength of the book is that it calls for a central role for alternative development in the current development discourse, most notably related to justice, rights, globalization, forced migration, conflict and climate change. The book provides new ways of engaging with alternative development thinking and making development alternatives relevant.
Alternative Ecological Risk Assessment: An Innovative Approach to Understanding Ecological Assessments for Contaminated Sites
by Lawrence V. TannenbaumIn Alternative Ecological Risk Assessment the author, Lawrence V. Tannenbaum, provides a critical review of current practices in the ecological risk assessment field and proposes alternatives that are supported by established science and keen observation. It is hoped that this approach will pave the way to a greater understanding of what appropriate and useful ecological assessment for contaminated sites should entail. He demonstrates that in most cases current practices do not provide for an assessment of ecological risk, and moreover, that endeavoring to assess ecological risk is actually an unnecessary undertaking at conventional hazardous waste sites. (He states, for example, that the concept of scale is often ignored by practitioners, questions why animals like deer are routinely assessed at 5-acre sites, and challenges the ecotoxicology data currently used.) The book is aimed at students and professionals in the fields of environmental science, ecology, ecotoxicology, and health risk assessment.

Alternative Energy Resources: The Way to a Sustainable Modern Society (The Handbook of Environmental Chemistry #99)
by Pankaj Pathak Rajiv Ranjan SrivastavaThis book reviews alternative and renewable energy resources in order to pave the way for a more sustainable production in the future. A multi-disciplinary team of authors provides a comprehensive overview of current technologies and future trends, including solar technologies, wind energy, hydropower, microbial electrochemical systems and various biomass sources for biofuel production. In addition, the book focuses on solutions for developing countries. Conventional energy sources are finite, and estimates suggest that they will be exhausted within a few decades. Finding a solution to this problem is a global challenge, and developing countries in particular are still highly dependent on fossil fuels due to their rapidly growing populations accompanied by a huge growth in primary energy consumption. Moreover, the most common conventional energy sources (coal and petroleum) are non-sustainable since their combustion exponentially increases greenhouse gas emissions. As such, there is a pressing need for clean energy based on alternative or renewable resources, not only to ensure energy supplies at an affordable price but also to protect the environment.
Alternative Energy Sources (Green Energy and Technology)
by Efstathios E MichaelidesAlternative Energy Sources is designed to give the reader, a clear view of the role each form of alternative energy may play in supplying the energy needs of the human society in the near future (20-50 years). The two first chapters on "energy demand and supply" and "environmental effects," set the tone as to why alternative energy is essential for the future. The third chapter gives the laws of energy conversion processes, as well as the limitations of converting one energy form to another. The section on exergy gives a quantitative background on the capability/potential of each energy source to produce power. The fourth, fifth and sixth chapters are expositions of fission and fusion nuclear energy, the power plants that may produce power from these sources and the issues that will frame the public debate on nuclear energy. The following five chapters include descriptions of the most common renewable energy sources (wind, solar, geothermal, biomass, hydroelectric) some of the less common sources (e.g. tidal and wave energy). The emphasis of these chapters will be on the global potential of each source, the engineering/technical systems that are used in harnessing the potential of each source, the technological developments that will contribute to wider utilization of the sources and environmental effects associated with their wider use. The last three chapters are: "energy storage," which will become an important issue if renewable energy sources are used widely. The fourteen chapters in the book have been chosen so that one may fit a semester University course around this book. At the end of every chapter, there are 10-20 problems and 1-3 suggestions of semester projects that may be assigned to students for further research.
