Motivated by several applications, we introduce various distance measures between “top k lists.” Some of these distance measures are metrics, while others are not. For each of these latter distance measures, we show that they are “almost ” a metric in the following two seemingly unrelated aspects: (i) they satisfy a relaxed version of the polygonal (hence, triangle) inequality, and (ii) there is a metric with positive constant multiples that bound our measure above and below. This is not a coincidence—we show that these two notions of almost being a metric are formally identical. Based on the second notion, we define two distance measures to be equivalent if they are bounded above and below by constant multiples of each other. We thereby identify a large and robust equivalence class of distance measures. Besides the applications to the task of identifying good notions of (dis)similarity between two top k lists, our results imply polynomialtime constantfactor approximation algorithms for the rank aggregation problem [DKNS01] with respect to a large class of distance measures.

This p~er studies the association between a finn's stock returns and subsequent top management chAMes. Con~ieut w~th mmml monitoring of management, there is an inverse relation between the probability of a management change and a firm's share performance. ~ relation can result from monitoring by the board, other top numagers, or b!oe?~older~. However, unless share performance is extremely good or bad, logit models have wo predictive ability. No average stock price reaction is detected a*. announcement of a top manasement change. 1. Introduefion This paper investigates the relation between a firm's stock price performance and subsequent changes in its top management. A top management change is defined as any change in the set of individuals holding the title of chief executive officer (CEO), president, or chairman of the board. The major hypothesis is that the probability of a top management change is inversely related to stock price performance. Using a random sample of listed firms, the hypothesis is tested with a prediction procedure to exploit information on firms that do not experience a management change. In addition, standard event study methodology is employed to study stock price reaction to announcement of management change. The p~oer provides new evidence on mechanisms for removing inefficient managers and encouraging managers to act in shareholders ' interests. Although external mechanisms such as the takeover market can serve this

We present an imagebased modeling and editing system that takes a single photo as input. We represent a scene as a layered collection of depth images, where each pixel encodes both color and depth. Starting from an input image, we employ a suite of userassisted techniques, based on a painting metaphor, to assign depths and extract layers. We introduce two specific editing operations. The first, a "clone brushing tool," permits the distortionfree copying of parts of a picture, by using a parameterization optimization technique. The second, a "textureilluminance decoupling filter," discounts the effect of illumination on uniformly textured areas, by decoupling large and smallscale features via bilateral filtering. Our system enables editing from different viewpoints, extracting and grouping of imagebased objects, and modifying the shape, color, and illumination of these objects.
