"... weathering the telecommunications storm: Is the forecast bright or gloomy? By Darryl C. Sterling and Charles Gerlach Staggered by a series of crushing blows, the global telecommunications (telecom) industry is in the midst of a full-blown industry depression. Even in early 2000, when the market capi ..."

capitalizations of many carriers had reached their zeniths, the seeds of the depression—debt, overcapacity, service commoditization, customer disaffection—had already taken root. Since then, resulting declines in earnings and the flight of capital from the industry have pummeled carriers in every region
MIXED MNL MODELS FOR DISCRETE RESPONSE
- JOURNAL OF APPLIED ECONOMETRICS J. APPL. ECON. 15: 447--470 (2000)
, 2000
"... This paper considers mixed, or random coefficients, multinomial logit (MMNL) models for discrete response, and establishes the following results. Under mild regularity conditions, any discrete choice model derived from random utility maximization has choice probabilities that can be approximated as ..."

An efficient algorithm for the sparse mixed resultant
- In Proceedings of AAECC
, 1993
"... We propose a compact formula for the mixed resultant ofa system of n+1 sparse Laurent polynomials in n variables. Our approach is conceptually simple and geometric, in that it applies a mixed subdivision to the Minkowski Sum of the input Newton polytopes. It constructs a matrix whose determinant is ..."

XORs in the air: practical wireless network coding
- In Proc. ACM SIGCOMM
, 2006
"... This paper proposes COPE, a new architecture for wireless mesh networks. In addition to forwarding packets, routers mix (i.e., code) packets from different sources to increase the information content of each transmission. We show that intelligently mixing packets increases network throughput. Our de ..."

An Empirical Characterization of the Dynamic Effects of changes in Government Spending and Taxes on Output
- QUARTERLY JOURNAL OF ECONOMICS
, 2002
"... This paper characterizes the dynamic effects of shocks in government spending and taxes on U. S. activity in the postwar period. It does so by using a mixed structural VAR/event study approach. Identification is achieved by using institutional information about the tax and transfer systems to identi ..."

Lightness and Retinex Theory
- JOURNAL OF THE OPTICAL SOCIETY OF AMERICA
, 1971
"... Sensations of color show a strong correlation with reflectance, even though the amount of visible light reaching the eye depends on the product of reflectance and illumination. The visual system must achieve this remarkable result by a scheme that does not measure flux. Such a scheme is described as ..."

Monopolistic competition and optimum product diversity. The American Economic Review,
, 1977
"... The basic issue concerning production in welfare economics is whether a market solution will yield the socially optimum kinds and quantities of commodities. It is well known that problems can arise for three broad reasons: distributive justice; external effects; and scale economies. This paper is c ..."

commodities already embodies the desirability of variety. Thus, a consumer who is indifferent between the quantities (1,0) and (0,1) of two commodities prefers the mix (1/2,1/2) to either extreme. The advantage of this view is that the results involve the familiar ownand cross-elasticities of demand functions
Biased assimilation and attitude polarization: The effects of prior theories on subsequently considered evidence
- Journal of Personality and Social Psychology
, 1979
"... People who hold strong opinions on complex social issues are likely to examine relevant empirical evidence in a biased manner. They are apt to accept "confirming" evidence at face value while subjecting "discontinuing " evidence to critical evaluation, and as a result to draw und ..."

undue support for their initial positions from mixed or random empirical findings. Thus, the result of exposing contending factions in a social dispute to an identical body of relevant empirical evidence may be not a narrowing of disagreement but rather an increase in polarization. To test
Review of B ¯B Mixing Results ∗
, 1999
"... A review of B ¯ B mixing results at the end of July 1999 is presented. Emphasis is put on recent measurements of ∆md and ∆ms. For ∆md, the new world average is ∆md = 0.473 ± 0.016 ps −1. For ∆ms, the new world average 95 % CL limit is 12.4 ps −1, with a sensitivity of 14.2 ps −1. Other related resul ..."

Mining the Peanut Gallery: Opinion Extraction and Semantic Classification of Product Reviews
, 2003
"... The web contains a wealth of product reviews, but sifting through them is a daunting task. Ideally, an opinion mining tool would process a set of search results for a given item, generating a list of product attributes (quality, features, etc.) and aggregating opinions about each of them (poor, mixe ..."

, mixed, good). We begin by identifying the unique properties of this problem and develop a method for automatically distinguishing between positive and negative reviews. Our classifier draws on information retrieval techniques for feature extraction and scoring, and the results for various metrics
