Book excerpt: Excerpt from Initial Results From the Pawnee Eddy Correlation System for Dry Acid Deposition Research Depending upon climate and the ambient atmospheric environment, 8, N, and ozone may be deposited by either dry processes or by precipitation. This paper discusses only the dry deposition process. At first glance measuring dry deposition might seem to be an easy task; for example, simply put out a bucket and measure what falls in when it is not raining. How ever, dry deposition measurements are not simple because the surfaces on which dry deposition occurs may themselves actively be removing the pollutant. Therefore, simple passive monitoring is not adequate for a full description of the dry deposition process. Some understanding of the nature of the underlying surface is also required. The most accurate techniques for measuring dry deposition employ aerodynamic methods. Essentially these involve measuring how much pollution passes by a fixed level in the atmosphere. This procedure works best when the vegetation is uniform and the terrain is flat. The research reported on in this paper represents a test of the aerodynamic method known as eddy cor relation under circumstances where it is expected to work well. Eventually, we plan to use eddy correlation to make dry deposition measurements in typical alpine and sub alpine ecosystems. These eddy correlation measure ments will then be used to confirm simpler technologies for routine measurements of the levels of S, N, and ozone present and depositing to forested lands.

Download or read book Program Evaluation Theory and Practice written by Donna M. Mertens and published by Guilford Press. This book was released on 2012-02-20 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: This engaging text takes an evenhanded approach to major theoretical paradigms in evaluation and builds a bridge from them to evaluation practice. Featuring helpful checklists, procedural steps, provocative questions that invite readers to explore their own theoretical assumptions, and practical exercises, the book provides concrete guidance for conducting large- and small-scale evaluations. Numerous sample studies—many with reflective commentary from the evaluators—reveal the process through which an evaluator incorporates a paradigm into an actual research project. The book shows how theory informs methodological choices (the specifics of planning, implementing, and using evaluations). It offers balanced coverage of quantitative, qualitative, and mixed methods approaches. Useful pedagogical features include: *Examples of large- and small-scale evaluations from multiple disciplines. *Beginning-of-chapter reflection questions that set the stage for the material covered. *"Extending your thinking" questions and practical activities that help readers apply particular theoretical paradigms in their own evaluation projects. *Relevant Web links, including pathways to more details about sampling, data collection, and analysis. *Boxes offering a closer look at key evaluation concepts and additional studies. *Checklists for readers to determine if they have followed recommended practice. *A companion website with resources for further learning.

Download or read book Pre Columbian Foodways written by John Staller and published by Springer Science & Business Media. This book was released on 2009-11-24 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significance of food and feasting to Pre-Columbian Mesoamerican cultures has been extensively studied by archaeologists, anthropologists and art historians. Foodways studies have been critical to our understanding of early agriculture, political economies, and the domestication and management of plants and animals. Scholars from diverse fields have explored the symbolic complexity of food and its preparation, as well as the social importance of feasting in contemporary and historical societies. This book unites these disciplinary perspectives — from the social and biological sciences to art history and epigraphy — creating a work comprehensive in scope, which reveals our increasing understanding of the various roles of foods and cuisines in Mesoamerican cultures. The volume is organized thematically into three sections. Part 1 gives an overview of food and feasting practices as well as ancient economies in Mesoamerica. Part 2 details ethnographic, epigraphic and isotopic evidence of these practices. Finally, Part 3 presents the metaphoric value of food in Mesoamerican symbolism, ritual, and mythology. The resulting volume provides a thorough, interdisciplinary resource for understanding, food, feasting, and cultural practices in Mesoamerica.

Download or read book Living Fossils written by N. Eldredge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The case history approach has an impressive record of success in a variety of disciplines. Collections of case histories, casebooks, are now widely used in all sorts of specialties other than in their familiar appli cation to law and medicine. The case method had its formal beginning at Harvard in 1871 when Christopher Lagdell developed it as a means of teaching. It was so successful in teaching law that it was soon adopted in medical education, and the collection of cases provided the raw material for research on various diseases. Subsequently, the case history approach spread to such varied fields as business, psychology, management, and economics, and there are over 100 books in print that use this approach. The idea for a series of Casehooks in Earth Science grew from my experience in organizing and editing a collection of examples of one variety of sedimentary deposits. The prqject began as an effort to bring some order to a large number of descriptions of these deposits that were so varied in presentation and terminology that even specialists found them difficult to compare and analyze. Thus, from the beginning, it was evident that something more than a simple collection of papers was needed. Accordingly, the nearly fifty contributors worked together with George de Vries Klein and me to establish a standard format for presenting the case histories.
Download or read book Primary Productivity of the Biosphere written by H. Lieth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The period since World War II, and especially the last decade influenced by the International Biological Program, has seen enormous growth in research on the function of ecosystems. The same period has seen an exponential' rise in environmental problems including the capacity of the Earth to support man's population. The concern extends to man's effects on the "biosphere"-the film of living organisms on the Earth's surface that supports man. The common theme of ecologic research and environmental concerns is primary production the binding of sunlight energy into organic matter by plants that supports all life. Many results from the IBP remain to be synthesized, but enough data are available from that program and other research to develop a convincing sum mary of the primary production of the biosphere-the purpose of this book. The book had its origin in the parallel interests of the two editors and Gene E. Likens, which led them to prepare a symposium on the topic at the Second Biological Congress of the American Institute of Biological Sciences in Miami, Florida, October 24, 1971. Revisions of the papers presented at that symposium appear as Chapters 2, 8, 9, 10, and 15 in this book. We have added other chapters that complement this core; these include discussion and evaluation of methods for measuring productivity and regional production, current findings on tropical productivity, and models of primary productivity.
Download or read book Routes and Roots written by Elizabeth DeLoughrey and published by University of Hawaii Press. This book was released on 2009-12-31 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elizabeth DeLoughrey invokes the cyclical model of the continual movement and rhythm of the ocean (‘tidalectics’) to destabilize the national, ethnic, and even regional frameworks that have been the mainstays of literary study. The result is a privileging of alter/native epistemologies whereby island cultures are positioned where they should have been all along—at the forefront of the world historical process of transoceanic migration and landfall. The research, determination, and intellectual dexterity that infuse this nuanced and meticulous reading of Pacific and Caribbean literature invigorate and deepen our interest in and appreciation of island literature. —Vilsoni Hereniko, University of Hawai‘i "Elizabeth DeLoughrey brings contemporary hybridity, diaspora, and globalization theory to bear on ideas of indigeneity to show the complexities of ‘native’ identities and rights and their grounded opposition as ‘indigenous regionalism’ to free-floating globalized cosmopolitanism. Her models are instructive for all postcolonial readers in an age of transnational migrations." —Paul Sharrad, University of Wollongong, Australia Routes and Roots is the first comparative study of Caribbean and Pacific Island literatures and the first work to bring indigenous and diaspora literary studies together in a sustained dialogue. Taking the "tidalectic" between land and sea as a dynamic starting point, Elizabeth DeLoughrey foregrounds geography and history in her exploration of how island writers inscribe the complex relation between routes and roots. The first section looks at the sea as history in literatures of the Atlantic middle passage and Pacific Island voyaging, theorizing the transoceanic imaginary. The second section turns to the land to examine indigenous epistemologies in nation-building literatures. Both sections are particularly attentive to the ways in which the metaphors of routes and roots are gendered, exploring how masculine travelers are naturalized through their voyages across feminized lands and seas. This methodology of charting transoceanic migration and landfall helps elucidate how theories and people travel, positioning island cultures in the world historical process. In fact, DeLoughrey demonstrates how these tropical island cultures helped constitute the very metropoles that deemed them peripheral to modernity. Fresh in its ideas, original in its approach, Routes and Roots engages broadly with history, anthropology, and feminist, postcolonial, Caribbean, and Pacific literary and cultural studies. It productively traverses diaspora and indigenous studies in a way that will facilitate broader discussion between these often segregated disciplines.
