Vision and Action
This book is about the two-way interplay between vision and action. Vision acts to guide and control actions. But vision also obtains a lot of information about the world by virtue of these actions --for example by moving round an object to obtain successive views. This becomes a reiterative process and it is this that is the focus of this volume. This book contains contributions from scientists who are leaders in each of the several facets of the subject. Examples of the types of action considered vary from moving the eyes and head and body, as in looking around or walking, to complex actions such as driving a car, or playing table tennis.
Vision in 3D Environments
Top researchers explore the latest cutting-edge research into the perception of 3D environments, presenting both biological and computational perspectives.
Levels of Perception
In this book the authors relate and discuss the idea that perceptual processes can be considered at many levels. A phenomenon that appears at one level may not be the same as a superficially similar phenomenon that appears at a different level. For example "induced motion" can be analyzed in terms of eye movements or at the retinal level or at a much higher cognitive level: how do these analyses fit together? The concept of levels also makes us think of the flow of information between levels, which leads to a consideration of the roles of top-down and bottom-up (or feed-forward, feed-back) flow. There are sections devoted to vestibular processing, eye movement processing and processing during brightness perception. The final section covers levels of processing in spatial vision. All scientists and graduate students working in vision will be interested in this book as well as people involved in using visual processes in computer animations, display design or the sensory systems of machines.

Trading and Electronic Markets: What Investment Professionals Need to Know
The true meaning of investment discipline is to trade only when you rationally expect that you will achieve your desired objective. Accordingly, managers must thoroughly understand why they trade. Because trading is a zero-sum game, good investment discipline also requires that managers understand why their counterparties trade. This book surveys the many reasons why people trade and identifies the implications of the zero-sum game for investment discipline. It also identifies the origins of liquidity and thus of transaction costs, as well as when active investment strategies are profitable. The book then explains how managers must measure and control transaction costs to perform well. Electronic trading systems and electronic trading strategies now dominate trading in exchange markets throughout the world. The book identifies why speed is of such great importance to electronic traders, how they obtain it, and the trading strategies they use to exploit it. Finally, the book analyzes many issues associated with electronic trading that currently concern practitioners and regulators.

Trading and Exchanges
Focusing on market microstructure, Harris (chief economist, U.S. Securities and Exchange Commission) introduces the practices and regulations governing stock trading markets. Writing to be understandable to the lay reader, he examines the structure of trading, puts forward an economic theory of trading, discusses speculative trading strategies, explores liquidity and volatility, and considers the evaluation of trader performance.

Multisensory Integration: Brain, Body and the World
Behavioral, language, and reasoning are expressions of neural functions par excellence, as the brain must draw on sensory modalities to gather information on the rest of the body and on the outer world. Cortical areas processing the identity and location of the sensory inputs were once thought to be organized, with some branches dedicated to complex features. Yet current studies have uncovered synergistic effects at early-stage cognitions as well as higher-level association areas. A less hierarchical functional architecture of the brain has emerged such that, irrespective of sensory modality, inputs are assigned to the best suited cortical substrate.
