This article is the first in a series that looks at the technological transformation of Des Moines Public Schools (DMPS). It concentrates on the costs, some financial but mostly human and organizational, that are emerging as the district begins to implement its plans for dramatically increasing computer technology use. The conclusion reached here is that not only ave the costs been greatly underestimated, they may even force a gradual shift of control over the learning environment.

In this groundbreaking new study, Lowell Nissen explores the use of teleological language in the study of subjects such as behaviorism, negative feedback, and natural selection. He argues that all existing analyses fail to explain how teleological language can be used legitimately, and provides his own analysis in terms of intentionality.

We examine the influence of word choices on mathematical practice, i.e. in developing definitions, theorems, and proofs. As a case study, we consider Euclid’s and Euler’s word choices in their influential developments of geometry and, in particular, their use of the term ‘polyhedron’. Then, jumping to the twentieth century, we look at word choices surrounding the use of the term ‘polyhedron’ in the work of Coxeter and of Grünbaum. We also consider a recent and explicit conflict of approach between Grünbaum (...) and Shephard on the one hand and that of Hilton and Pedersen on the other, elucidating that the conflict was engendered by disagreement over the proper conceptualization, and so also the appropriate word choices, in the study of polyhedra.

Ludwig Wittgenstein is perhaps the greatest philosopher of the twentieth century, and certainly one of the most original in the entire Western tradition. Given the inaccessibility of his work, it is remarkable that he has inspired poems, paintings, films, musical compositions, titles of books -- and even novels. In his splendid biography, Ray Monk has made this very compelling human being come alive in a way that perfectly explains the fascination he has evoked. Wittgenstein's life was one of great moral (...) and spiritual depth. Although his work addresses problems of logic, language, mind, and knowledge, he often described it as having an ethical point, and once said that he "could not help seeing every problem from a religious point of view." In successfully bridging the gap assumed by many to exist between Wittgenstein's life and his work, Monk's biography helps to explain the interest in Wittgenstein's later philosophy on the part of Buddhist scholars.

We question whether altruistic motivation links identity fusion and extreme self-sacrifice. We review two lines of research suggesting that the underlying motivation is plausibly egoistic.

PROSPERITY AND UPHEAVAL: THE WORLD ECONOMY 1945?1980 by Herman Van der Wee translated by Robin Hogg and Max R. Hall Berkeley: University of California Press, 1987. 621pp., $14.95 Van der Wee uncritically accepts that Keynesianism is responsible for post?war economic stability. Against this belief, it is argued that an analysis of the historical record shows no significant efforts at countercyclical fiscal management in the post?war era, while efforts to control the economy via monetary policy were associated with increasing instability, culminating (...) in the crisis years of the 1970s. Thus, in the American case at least, post?war stability has been the result of self?correcting market tendencies, while instability has followed government macroeconomic intervention. (shrink)

There are compelling medical, ethical, and legal arguments that support mandating use of a central institutional review board for the review of clinical trials performed at multiple institutional sites. Progress against serious diseases depends on this.

For any Boolean Algebra A, let cmm be the smallest size of an infinite partition of unity in A. The relationship of this function to the 21 common functions described in Monk [4] is described, for the class of all Boolean algebras, and also for its most important subclasses. This description involves three main results: the existence of a rigid tree algebra in which cmm exceeds any preassigned number, a rigid interval algebra with that property, and the construction of an (...) interval algebra in which every well-ordered chain has size less than cmm.

Edmund Burke's work spans a variety of subjects - from aesthetics through history to constitutional politics and political theory - and has generated an enormous literature drawing on many disciplines, and it continues to feature in a range of contemporary polemics. This volume brings together a representative selection of articles and essays from the last 50 years of this scholarship, and includes an introduction which guides the reader through the selection as well as offering pointers towards more substantial studies that (...) form the critical heritage of this major figure.

Burke's Reflections on the Revolution in France was the first sustained theoretical critique of the French Revolution; and is now recognised as the classic statement of modern conservatism. Reflections surveys the British political culture of traditionalism, gradualism and deference, and contrasts it with the French Revolutionaries' programme of appeal to abstract right, transformational change and popular agency. Ultimately Burke advocated a counterrevolutionary war and the restoration of the French monarchy. This accessible new edition brings together for the first time Burke's (...) first and last published thoughts on the revolution including as it does the first Letter on a Regicide Peace; a work that has contributed to a particular view of international society. Featuring a comprehensive introduction and extensive annotations, Iain Hampsher-Monk's edition helps readers new to Burke to better understand the historical, political and philosophical context behind his writings, and the significance of contemporary and classical allusions.

De Long's criticisms of our explanation of unemployment patterns in the United States are empirically false. His assertion that we have the direction of causation reversed collapses in light of the lag between artificially high wages and unemployment. Nor are his claims about the nature of cyclical movements in productivity and real wages consistent with the data. Finally, his contention that the model we present does not work in the post‐World War II era is, at best, misleading. The evidence shows (...) with remarkable consistency that government attempts to prop up wages have caused twentieth‐century increases in U.S. employment. (shrink)
