In this essay, Leonard Waks contributes to a reconceptualization of ‘‘fundamental educational change.’’ By distinguishing sharply between educational change at the organizational and the institutional levels, Waks shows that the mechanisms of change at these two levels are entirely different. He then establishes, by means of a conceptual argument, that fundamental educational change takes place...

A formula for the revenue maximizing top tax rate is derived as a function of three elasticities. The formula applies to static models and to steady states of dynamic models and is relevant for the top tax rate on any component of income. The formula is applied to several classic models. The application of the formula is also illustrated using a quantitative human capital model. © 2017 Elsevier...

From the Editors: This year marks the hundredth year of genetics as a science, while the next two years mark the turning of the millennium. The year 1900 saw the rediscovery of Mendel’s laws by DeVries, Correns, and Tschermak, and the revolution that was set forth by this triple confirmation has had few equals in science. Our way of celebrating this anniversary has been to invite another look a...

Extracting open relational tuples that are mediated by nouns (instead of verbs) is important since titles and entity attributes are often expressed nominally. While appositives and possessives are easy to handle, a difficult and important class of nominal extractions requires interpreting compound noun phrases (e.g., “Google CEO Larry Page”). We substantially improve the quality of Open IE from...

For Larry Markus on the occasion of his 70 th birthday. ABSTRACT: We consider a model for the radially symmetric evolution (by accretion or dissolution) of the interface between a `pure' solid grain and a liquid solution of the same substance with diiusion both of material and heat. After analyzing the direct problem, we show existence of optimal controls .

Question 1.2. Suppose g(k) is the least number of powers to make Theorem 1.1 hold. How big is g(k)? To provide some intuition, take n = 2−1. In its decomposition any ai can’t be greater than 1, since 2 k > 2 − 1. Therefore, ai = 1 for all i and g(k) ≥ s = 2 − 1. The real value of g(k) is only a little worse than that. Thus, the number g(k) grows at least exponentially with respect to k. However...
