Using Maimonides’ Rule to Estimate the Effect of Class Size on Scholastic Achievement
 QUARTERLY JOURNAL OF ECONOMICS
, 1999
"... The twelfth century rabbinic scholar Maimonides proposed a maximum class size of 40. This same maximum induces a nonlinear and nonmonotonic relationship between grade enrollment and class size in Israeli public schools today. Maimonides’ rule of 40 is used here to construct instrumental variables e ..."

New tight frames of curvelets and optimal representations of objects with piecewise C² singularities
 COMM. ON PURE AND APPL. MATH
, 2002
"... This paper introduces new tight frames of curvelets to address the problem of finding optimally sparse representations of objects with discontinuities along C2 edges. Conceptually, the curvelet transform is a multiscale pyramid with many directions and positions at each length scale, and needleshap ..."

Manipulation of the running variable in the regression discontinuity design: A density test
 Journal of Econometrics 142
, 2008
"... Standard sufficient conditions for identification in the regression discontinuity design are continuity of the conditional expectation of counterfactual outcomes in the running variable. These continuity assumptions may not be plausible if agents are able to manipulate the running variable. This pap ..."

Randomized Experiments from Nonrandom Selection in the U.S. House Elections
 Journal of Econometrics
, 2008
"... This paper establishes the relatively weak conditions under which causal inferences from a regressiondiscontinuity (RD) analysis can be as credible as those from a randomized experiment, and hence under which the validity of the RD design can be tested by examining whether or not there is a discont ..."

Depth Discontinuities by PixeltoPixel Stereo
, 1999
"... An algorithm to detect depth discontinuities from a stereo pair of images is presented. The algorithm matches individual pixels in corresponding scanline pairs, while allowing occluded pixels to remain unmatched, then propagates the information between scanlines by means of a fast postprocessor. Th ..."

Cultivating competence, selfefficacy, and intrinsic interest through proximal selfmotivation.
 Journal of Personality and Social Psychology,
, 1981
"... Abstract: The present experiment tested the hypothesis that selfmotivation through proximal goal setting serves as an effective mechanism for cultivating competencies, selfpercepts of efficacy, and intrinsic interest. Children who exhibited gross deficits and disinterest in mathematical tasks pur ..."

Essentially nonoscillatory and weighted essentially nonoscillatory schemes for hyperbolic conservation laws
, 1998
"... In these lecture notes we describe the construction, analysis, and application of ENO (Essentially NonOscillatory) and WENO (Weighted Essentially NonOscillatory) schemes for hyperbolic conservation laws and related HamiltonJacobi equations. ENO and WENO schemes are high order accurate nite di ere ..."

A MaximumFlow Formulation of the Ncamera Stereo Correspondence Problem
, 1998
"... This paper describes a new algorithm for solving the Ncamera stereo correspondence problem by transforming it into a maximumflow problem. Once solved, the minimumcut associated to the maximumflow yields a disparity surface for the whole image at once. This global approach to stereo analysis provi ..."

as well as better handling of depth discontinuities. While the worst case running time is O(n 2 d 2 log(nd)), the observed average running time is O(n 1:2 d 1:3 ) for an image size of n pixels and depth resolution d. 1 Introduction It is well known that depth related displacements in stereo
Nonlinear Image Recovery with HalfQuadratic Regularization
, 1993
"... One popular method for the recovery of an ideal intensity image from corrupted or indirect measurements is regularization: minimize an objective function which enforces a roughness penalty in addition to coherence with the data. Linear estimates are relatively easy to compute but generally introduce ..."
