The authors introduce this new approach to programming language design, describe its evolution and design principles, and present a formal specification of a metaobject protocol for CLOS. The CLOS metaobject protocol is an elegant, high-performance extension to the CommonLisp Object System. The authors, who developed the metaobject protocol and who were among the group that developed CLOS, intr…
This series is for people--adults and teenagers--who are interested in computer programming because it's fun. The three volumes use the Logo programming language as the vehicle for an exploration of computer science from the perspective of symbolic computation and artificial intelligence. Logo is a dialect of Lisp, a language used in the most advanced research projects in computer science, espe…

Studies of the relation between information technology and economic growth trends.The relentless decline in the prices of information technology (IT) has steadily enhanced the role of IT investment as a source of economic growth in the United States. Productivity growth in IT-producing industries has gradually risen in importance, and a productivity revival has taken place in the rest of the ec…
The essays in this volume provide a comprehensive view of applications of the cost of capital.The essays in this volume provide a comprehensive view of applications of the cost of capital. The cost of capital is the key concept in the analysis of taxation of business income. It is also critical to the formulation of a new system of national accounts, where it plays the role of the price of capi…
New methodology for econometricians, based on the dual formulation of the theory of production in terms of prices. The objectives of econometric modeling of producer behavior are to determine the nature of substitution among inputs and outputs and of differences in technology, as well as the role of economies of scale in production. Recent advances in methodology, based on the dual formulation …
A realistic yet encouraging look at how society can change in ways that will allow us to feed an expanding global population.This book addresses the question of how we can best feed the ten billion or so people who will likely inhabit the Earth by the middle of the twenty-first century. He asks whether human ingenuity can produce enough food to support healthy and vigorous lives for all these p…
These original essays summarize a decade of fruitful research and curriculum development using the LISP-derived language Logo. They discuss a range of issues in the areas of curriculum, learning, and mathematics, illustrating the ways in which Logo continues to provide a rich learning environment, one that allows pupil autonomy within challenging mathematical settings.Essays in the first sectio…
"A Bradford Book."Over the past two decades, Ray Jackendoff has persistently tackled difficult issues in the theory of mind and related theories of cognitive processing. Chief among his contributions is a formal theory that elaborates the nature of language and its relationship to a broad set of other domains. Languages of the Mind provides convenient access to Jackendoff's work over the past f…
