Cactus flowers are jewels of the desert--they add brilliant pops of color to our arid surroundings. In this book, renowned Tucson photographer John P. Schaefer brings the exquisite and unexpected beauty of the cactus flower to the page. Hundreds of close-up photographs of cactus flowers native to the U.S. Southwest and Mexico offer a visual feast of color and texture, nuance and light. These stunning photographs allow us to appreciate the spectacular range of color and form cactus flowers have to offer. For the cactus enthusiast, the book offers a comprehensive collection of high-quality flower photographs unlike any other. The photographs cover more than 250 cactus species organized by genus. The book starts with an introduction by the photographer that is both autobiographical and informative. It offers a glimpse into his process for capturing these elusive desert gems, resulting in photographs so beautiful they were featured as a book of stamps issued by the U.S. Postal Service. This collection of cactus flowers in bloom is a one-of-a-kind work by a master photographer.
In recent years, the rapidly growing field of community participation has promised to give people formerly excluded from decision making an influential voice about issues that affect their lives. Inclusive processes implemented in the United States and internationally have certainly given community members new opportunities to participate and be involved, but how effective are these processes in promoting the voice and influence of the people who have historically been excluded the most--the poorest, least educated, and most marginalized residents in communities? Of the various participants who have "a seat at the table," whose voices are influential, whose aren't, and why? This book summarizes how five community partnerships, working with a team of researchers, attempted to answer these critical questions. Investigating 10 cases--two from each community partnership--the study tracks the ideas of everyone involved and reveals how and why the ideas of marginalized and ordinary residents were far less likely to be influential than those of people with more clout, resources, or acknowledged expertise. Finally, the authors explain how and why these influence inequities can be overcome, providing readers with practical, evidence-based tools to help them do so. The book should be helpful to readers involved in any form of active community participation, from participatory research to civic engagement, deliberative democracy, and community initiatives.

This is a psychological and historical exploration of belief in a spirit world, imperceptible to the senses, as a pervasive and deeply-rooted characteristic of religion.
Never before has a comprehensive history of the pancreas like History of the Pancreas been published. It not only is a historical review of the science of medicine, it is liberally interspersed with anecdotal vignettes of the researchers who have worked on this organ. Much of it, such as the discovery of the duct of Wirsüng, of the islets of Langerhans, of insulin, gastrin and their tumors, reads like the adverture, which it is. This book, divided into 14 chapters, is written in a narrative style and is easily readable, as glimpses of the investigators, those who failed as well as those who succeeded, adds both perspective and human interest. Each chapter is completely referenced, totaling over 1500 references. As a reference book for students, teachers, investigators, writers, its detailed hjistorical documentation is unique. From the pre-Christian era of Asia Minor, to Greece, Rome, Europe and America, to the explosive progress in Japan, the history is there. History of the Pancreas: Mysteries of a Hidden Organ fills a gap.
This outstanding thesis describes a detailed investigation into the use of low-oxidation-state group 14 complexes in catalysis, developed at the cutting edge of inorganic and organometallic chemistry. It includes the preparation of a number of landmark compounds, some of which challenge our current understanding of metal–metal bonding and low-oxidation-state main group chemistry. Among the many highlights of this thesis, the standout result is the development of the first well-defined, low- oxidation-state main group hydride systems as highly efficient catalysts in the hydroboration of carbonyl substrates, including carbon dioxide, which are as efficient as those observed in more traditional, transition-metal catalyses. These results essentially define a new subdiscipline of chemistry.
Weaknesses in understanding of tuna distributions and movements have constrained the development of rational management policies. Uncertainties exist in: the selection of management plans and catch and effort data that are representative of a stock; quantification of exchange of adults among management jurisdictions and fishing gears; and identification of the relationships between the environment and tuna movements. This report summarizes a series of discussions between a panel and groups of experts on how to increase understanding of these and other tuna problems. We discuss the uncertainties in current management policy caused by lack of understanding of tuna movement dynamics. We describe and evaluate the research approaches presently used to describe the movements of tunas--mark and recapture and acoustic tracking-- and those which might be used or are just being applied, including new tagging systems, measurement of physiological state and microconstituents of mineralized tissue. Actions needed to improve the knowledge of tuna movements are: 1) establish international arrangements to share tuna movement data, to analyse movements on an oceanwide and worldwide basis and to link international oceanographic programs; 2) increase number and kinds of observations of movements of tuna in the vertical plane; 3) develop and use technology for tracing the actual paths followed by tunas over extended periods and for measuring movements independent of the fishery; and 4) conduct intensive studies on tuna movement dynamics which combine old with the new technologies discussed in the report.

Now with an improved color art program, thorough updates reflecting today's medicine and science, this textbook is an excellent source for mastering essential human physiology knowledge. Learn and remember vital concepts easily thanks to short, easy-to-read, masterfully edited chapters and a user-friendly full-color design. See core concepts applied to real-life situations with clinical vignettes throughout the text. Discover the newest in physiology with updates that reflect the latest advances in molecular biology, cardiovascular, neurophysiology and gastrointestinal topics. Visualize physiologic principles clearly with over 1000 bold, full-color drawings and diagrams. Distinguish core concepts from more in-depth material with a layout that uses gray shading to clearly differentiate between "need-to-know" and "nice-to-know" information.
In this important attempt to reorient the theory and practice of public management, Stewart Ranson and John Stewart argue that public organisations must be analysed in terms of the distinctive values, purposes, tasks and conditions of the public domain. They show how it is only on this basis that they can meet the needs of citizens in a mature democracy and support the processes of a learning society.
