This article provides a self-contained introduction to my work from a recent perspective. A thought experiment is offered which analyses how a system as a whole can correct errors of hypothesis testing in a fluctuating environment when none of the system’s components, taken in isolation, even knows that an error has occurred. This theme is of general philosophical interest: How can intelligence or knowledge be ascribed to a system as a whole but not to its parts? How can an organism’s adaptive mechanisms be stable enough to resist environmental fluctuations which do not alter its behavioral success, but plastic enough to rapidly change in response to environmental demands that do alter its behavioral success? To answer such questions, we must identify the functional level on which a system’s behavioral success is defined.

From Stokes's (1963) early critique on, it has been clear to empirical researchers that the traditional spatial theory of elections is seriously flawed. Yet fully a quarter century later, that theory remains the dominant paradigm for understanding mass-elite linkage in politics. We present an alternative spatial theory of elections that we argue has greater empirical verisimilitude. Based on the ideas of symbolic politics, the directional theory assumes that most people have a diffuse preference for a certain direction of policy-making and that people vary in the intensity with which they hold those preferences. We test the two competing theories at the individual level with National Election Study data and find the directional theory more strongly supported than the traditional spatial theory. We then develop the implications of the directional theory for candidate behavior and assess the predictions in light of evidence from the U.S. Congress.

A Directional Theory of Issue Voting.

Is your memory hierarchy stopping your microprocessor from performing at the high level it should be? Memory Systems: Cache, DRAM, Disk shows you how to resolve this problem. The book tells you everything you need to know about the logical design and operation, physical design and operation, performance characteristics and resulting design trade-offs, and the energy consumption of modern memory hierarchies. You learn how to to tackle the challenging optimization problems that result from the side-effects that can appear at any point in the entire hierarchy.As a result you will be able to design and emulate the entire memory hierarchy. . Understand all levels of the system hierarchy -Xcache, DRAM, and disk. . Evaluate the system-level effects of all design choices. . Model performance and energy consumption for each component in the memory hierarchy.
