This book provides a systematic description of the molecular structures and bonding in simple compounds of the main group elements with particular emphasis on bond distances, bond energies and coordination geometries. The description includes the structures of hydrogen, halogen and methyl derivatives of the elements in each group, some of these molecules are ionic, some polar covalent. The survey of molecules whose structures conform to well-established trends is followed byrepresentative examples of molecules that do not conform. We also describe electron donor-acceptor and hydrogen bonded complexes.Chemists use models to systematize our knowledge, to memorize information and to predict the structures of compounds that have not yet been studied. The book provides a lucid discussion of a number of models such as the Lewis electron-pair bond and the VSEPR models, the spherical and polarizable ion models, and molecular orbital calculations, and it outlines the successes and failures of each.
Arne Naess is considered one of the most important philosophers of the twentieth century. He has been a tremendously prolific author, yet his works as a whole have remained largely unavailable – until now. Springer made available for the first time, a definitive 10-volume collection of Arne Naess’s life’s works: The Selected Works of Arne Naess. The Selected Works of Arne Naess (SWAN) presents a major overview of Arne Naess’s thinking and provides an extensive collection of this prolific philosopher’s principal writings. Some of Naess’s most important publications have never before been available in English. Many others are out of print. Often, his papers were published in obscure and inaccessible journals. And because Naess has been so prolific, many of his most important papers still remain unpublished. The publication of SWAN makes Naess’s work more fully accessible to scholars, students, and critics alike.
This volume paints a general picture of the environmental situation in Asia, backing it up with several case studies. Two major points are made in this general picture. The first is that environmental campaigns in Asia tend to have a local focus; they react to very concrete problems in the immediate neighbourhood and as such usually people are engaged in a cause for practical rather than idealistic reasons. Such can be seen in case studies from the volume dealing with campaigns against logging and tree plantations, tourist facilities and factories and in support or defence of nature reserves. This pattern is in marked contrast to the profile of the most successful Western movements (in terms of fund-raising at least) for whom the focus is on perceived problems in distant parts of the world. The second point is evidence in several of the case studies in the volume, namely that environmental campaigns cannot be understood in terms of environmental issues alone. Rather, they should be regarded as a form of cultural critique and frequently are a form of political resistance in situations where open political action is too risky.
