Fewer Men, More Babies re-evaluates the debate over family patterns in the Caribbean with respect to the critical importance that child labor plays in peasant household livelihood strategies. Earlier anthropologists widely accepted and provided empirical evidence that the contributions made by children to the peasant household labor pool was a significant determinant of social patterns and high birth rates. In the 1960s researchers began to dismiss the economic utility of children. Children were conceptualized as economic burdens, wanted for emotional, religious, and cultural reasons. This ideational trend emerged in the context of changes in Western economies and corresponding shifts in ideology; it reflected agendas promoted and exported to the developing world by aid agencies; and it derailed the refinement of academic models that explain kinship and high fertility. This shortcoming is especially evident in the Caribbean. Based on original ethnographic research, this book demonstrates how the process unfolds in contemporary rural Haiti; how intensive work regimes make children necessary; how this necessity conditions sexual behavior, gender relations, and kinship; and why, despite massive contraceptive campaigns, birth rates in rural Haiti continue to be among the highest in the world. Schwartz offers a solution to a demographic paradox that some of the most prominent sociologists and demographers of the 20th century noted but were never able to explain: among impoverished small farmers, when more men are absent due to male wage migration, the women remaining behind give birth to more, not fewer, babies.

Being a consumer is now integral to the human experience, something none of us can avoid. At the same time, many of the products that we buy come to us with histories steeped in highly unethical practices, such as worker exploitation, animal suffering, and environmental damage. Consuming Choices considers the ethical dimensions of consumer life by exploring several basic questions: Exactly what sorts of unethical practices are implicated in today's consumer products? Does moral culpability for these practices fall solely on the companies that perform them, or does it also fall upon consumers who purchase the products made with such practices? And most importantly, do consumers ever have moral obligations to avoid particular products? To answer, David T. Schwartz provides the most detailed philosophical exploration to date on consumer ethics. He utilizes historical and fictional examples to illustrate the types of wrongdoing currently implicated by consumer products in this age of globalization, offers a clear description of the relevant moral theories and important ethical concepts, and provides concrete suggestions on how to be a more ethical consumer.

This title, first published in 1965, provides an analysis of the forces and mechanisms governing the formation of the overall level of money prices. Even though this problem has a long history, and in spite of its obvious practical importance, it remains one of the most poorly understood questions in economic theory. This title will be of interest to students of monetary economics and the history of economic thought.

First published in 1987, the seven chapters that comprise this book review contemporary work on the geometric side of robotics. The first chapter defines the fundamental goal of robotics in very broad terms and outlines a research agenda each of whose items constitutes a substantial area for further research. The second chapter presents recently developed techniques that have begun to address the geometric side of this research agenda and the third reviews several applied geometric ideas central to contemporary work on the problem of motion planning. The use of Voronoi diagrams, a theme opened in these chapters, is explored further later in the book. The fourth chapter develops a theme in computational geometry having obvious significance for the simplification of practical robotics problems - the approximation or decomposition of complex geometric objects into simple ones. The final chapters treat two examples of a class of geometric 'reconstruction' problem that have immediate application to computer-aided geometric design systems.

This must-read text presents the pioneering work of the late Professor Jacob (Jack) T. Schwartz on computational logic and set theory and its application to proof verification techniques, culminating in the AEtnaNova system, a prototype computer program designed to verify the correctness of mathematical proofs presented in the language of set theory. Topics and features: describes in depth how a specific first-order theory can be exploited to model and carry out reasoning in branches of computer science and mathematics; presents an unique system for automated proof verification in large-scale software systems; integrates important proof-engineering issues, reflecting the goals of large-scale verifiers; includes an appendix showing formalized proofs of ordinals, of various properties of the transitive closure operation, of finite and transfinite induction principles, and of Zorn's lemma.

This is a volume of essays and reviews that delightfully explores mathematics in all its moods - from the light and the witty, and humorous to serious, rational, and cerebral. These beautifully written articles from three great modern mathematicians will provide a source for supplemental reading for almost any math class. Topics include: logic, combinatorics, statistics, economics, artificial intelligence, computer science, and broad applications of mathematics. Readers will also find coverage of history and philosophy, including discussion of the work of Ulam, Kant, and Heidegger, among others.
