This new seventh edition of the book offers extensivediscussion of information, uncertainty, and game theory. Itcontains over a hundred examples illustrating the applicability ofeconomic analysis not only to mainline economic topics but alsoissues in politics, history, biology, the family, and many otherareas. These discussions generally describe recent researchpublished in scholarly books and articles, giving students a goodidea of the scientific work done by professional economists. Inaddition, at appropriate places the text provides 'applications'representing more extended discussions of selected topics includingrationing in wartime (Chapter 5), import quotas (Chapter 7),alleged monopolistic suppression of inventions (Chapter 9), minimumwage laws (Chapter 11), the effects of Social Security upon saving(Chapter 15), fair division of disrupted property (Chapter 16) andwhether individuals should pay ransom to a kidnapper (Chapter17).

This textbook is aimed at newcomers to nonlinear dynamics andchaos, especially students taking a first course in the subject.The presentation stresses analytical methods, concrete examples andgeometric intuition. The theory is developed systematically,starting with first-order differential equations and theirbifurcations, followed by phase plane analysis, limit cycles andtheir bifurcations, and culminating with the Lorenz equations,chaos, iterated maps, period doubling, renormalization, fractals,and strange attractors. A unique feature of the book is itsemphasis on applications. These include mechanical vibrations,lasers, biological rhythms, superconducting circuits, insectoutbreaks, chemical oscillators, genetic control systems, chaoticwaterwheels, and even a technique for using chaos to send secretmessages. In each case, the scientific background is explained atan elementary level and closely integrated with the mathematicaltheory. Richly illustrated, and with many exercises and workedexamples, this

Easily the most influential book published in the nineteenthcentury, Darwin’s The Origin of Species is also that mostunusual phenomenon, an altogether readable discussion of ascientific subject. On its appearance in 1859 it was immediatelyrecognized by enthusiasts and detractors alike as a work of thegreatest importance: the revolutionary theory of evolution by meansof natural selection that it presented provoked a furious reactionthat continues to this day. The Origin of Species is here published together withDarwin’s earlier Voyage of the ‘Beagle’. This 1839 accountof the journeys to South America and the Pacific islands that firstput Darwin on the track of his remarkable theories derives an addedcharm from his vivid de*ion of his travels in exotic placesand his eye for the piquant detail.

The object of this book is to present a complete, systematic andthorough exposition of the neoclassical theory of production anddistribution. Despite this basic objective, each chapter presentsextensions of neoclassical theory and interpretations ofestablished relations. The book has two distinct parts. In Part Ithe microeconomic theories of production, cost and derived inputdemand are explored in depth for both fixed-proportions andvariable-proportions production functions. Special emphasis isplaced upon the characteristics and implications of productionfunctions homogeneous of degree one. Part II is devoted chiefly tothe neoclassical theory of aggregate relative factor shares, theelasticity of substitution, and technological progress.

One of the major neuropsychological models of personality,developed by world-renowned psychologist Professor Jeffrey Gray, isbased upon individual differences in reactions to punishing andrewarding stimuli. This biological theory of personality - nowwidely known as 'Reinforcement Sensitivity Theory' (RST) - has hada major influence on motivation, emotion and psychopathologyresearch. In 2000, RST was substantially revised by Jeffrey Gray,together with Neil McNaughton, and this revised theory proposedthree principal motivation/emotion systems: the'Fight-Flight-Freeze System' (FFFS), the 'Behavioural ApproachSystem' (BAS) and the 'Behavioural Inhibition System' (BIS). Thisis the first book to summarise the Reinforcement Sensitivity Theoryof personality and bring together leading researchers in the field.It summarizes all of the pre-2000 RST research findings, explainsand elaborates the implications of the 2000 theory for personalitypsychology and lays out the future research agenda for RST.
