Book excerpt: This action plan chronicles the threats faced by wild orchids, but more importantly to critical habitats that host extraordinarily high orchid diversity and endemicity. It explores and recommends specific ways that national and local government, legislators, scientists and orchid conservationists as well as growers can all help to reverse present trends. The facts and viewpoints presented in this comprehensive document update and supplement the information available to conservation organizations and agencies through the world so that they can lobby their appropriate government offices more effectively.

Available in PDF, EPUB and Kindle. Book excerpt: A Personal Note I decided to initiate Orchid Biology: Reviews and Perspectives in about 1972 and (alone or with co-authors) started to write some of the chapters and the appendix for the volume in 1974 during a visit to the Bogor Botanical Gardens in Indonesia. Professor H. C. D. de Wit of Holland was also in Bogor at that time and when we discovered a joint interest in Rumphius he agreed to write a chapter about him. I visited Bangkok on my way home from Bogor and while there spent time with Professor Thavorn Vajrabhaya. He readily agreed to write a chapter. The rest of the chapters were solicited by mail and I had the complete manuscript on my desk in 1975. With that in hand I started to look for a publisher. Most of the publishers I contacted were not interested. Fortunately Mr James Twiggs, at that time editor of Cornell University Press, grew orchids and liked the idea. He decided to publish Orchid Biology: Reviews and Per spectives, and volume I saw the light of day in 1977. I did not know if there would be a volume II but collected manuscripts for it anyway. Fortunately volume I did well enough to justify a second book, and the series was born. It is still alive at present - 20 years, seven volumes and three publishers later. I was in the first third of my career when volume I was published.

Download or read book Linear Optimization written by Glenn Hurlbert and published by Springer Science & Business Media. This book was released on 2009-11-09 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Subject A little explanation is in order for our choice of the title Linear Opti- 1 mization (and corresponding terminology) for what has traditionally been called Linear Programming.Theword programming in this context can be confusing and/or misleading to students. Linear programming problems are referred to as optimization problems but the general term linear p- gramming remains. This can cause people unfamiliar with the subject to think that it is about programming in the sense of writing computer code. It isn’t. This workbook is about the beautiful mathematics underlying the ideas of optimizing linear functions subject to linear constraints and the algorithms to solve such problems. In particular, much of what we d- cuss is the mathematics of Simplex Algorithm for solving such problems, developed by George Dantzig in the late 1940s. The word program in linear programming is a historical artifact. When Dantzig ?rstdevelopedthe Simplex Algorithm to solvewhat arenowcalled linear programming problems, his initial model was a class of resource - location problems to be solved for the U.S. Air Force.
