Frank Knight – författare

Joseph M. Forshaw, one of the world’s leading authorities on parrots, calls attention to the threats they face: they are one of the most endangered groups of birds, with a growing number of species nearing extinction. The main threats arise from habitat loss through deforestation and agricultural development and from the taking of birds for the international live-bird trade.

Vanished and Vanishing Parrots brings together information on species that have become extinct in historical times with information on species that are in danger of becoming extinct to increase public awareness of the plight of these magnificent birds. Vivid colour plates by the wildlife artist Frank Knight draw attention to the spectacular species that we have lost or that could be lost. Forshaw’s work gives us fascinating insight into these endangered and extinct parrots.

Vanished and Vanishing Parrots will be a valuable reference for scientific, ornithological and avicultural organisations, as well as individual lovers of birds and of illustrated natural history books.

When originally released, Frank Hyneman Knight''s The Economic Organization revitalized the teaching of economic theory in America during the 1930s, laying the foundation for the price theory revolution led by economists emerging from Knight''s circle at The University of Chicago. Knight shows that when societies choose to allow market organization, their economy simultaneously solves the fundamental functions of valuation and efficiency. It also organizes the production and distribution of resources, providing incentives for progress.

The Economic Organization provides a short introduction to the basic principles of supply, demand, and distribution that emerge from neoclassical price theory. The central role of the price mechanism in market organization is illustrated neatly by Knight''s "wheel of wealth" the circular flow diagram most often identified with macroeconomic flows, but introduced here for price theoretic reasons. This version also includes his essay on "Utility and Cost," which provides a seamlessly integrated alternative-cost interpretation of neoclassical theory.

This expanded edition of The Economic Organization includes a new introduction by Ross B. Emmett, which expands upon the short note on capital theory inserted in the original. Knight wrote three versions of the note for student use, and all three are included in the second chapter. Few books have changed the landscape of American economics and economic education as much as Knight''s The Economic Organization. This book should be read by all economists, historians, and policy makers.

Throughout much of the world, frog populations are declining, with the survival of many species under threat. In Australia, several species have become extinct in the past 35 years.

This second edition of Field Guide to the Frogs of Australia provides fully updated accounts of all the known frogs of Australia. There are 248 species within the five native frog families: Hylidae, Limnodynastidae, Microhylidae, Myobatrachidae and Ranidae. Also included are the introduced Cane Toad and nine ‘stowaway’ species that have arrived in Australia.

Each species account includes details of size, status, distribution, habitat, behaviour and advertisement call. Species are beautifully illustrated with full-colour paintings and distribution maps are also included. Closely related frogs are shown in identical poses so that comparisons can be made readily. The introductory section of the book covers frog biology and habitats and includes notes on families and genera.
