The perceived colors of an image seen on a self-luminous display are affected by viewing flare and perceptual phenomena, both of which vary with the ambient illumination. A framework for a display system that is capable of adapting its output to varying viewing environments is introduced. The proposed system uses a light sensor such as a CCD camera to estimate properties of ambient illumination...

We study how the pre-existing social network ties between the CEO and outside board members are associated with the firms’ voluntary financial disclosure practices, proxied by management earnings guidance. We construct social network ties by considering the social ties in addition to the statutory ties. After controlling firm and year fixed effects, we find a substantially strong, negative rela...

The aim in this study was to estimate variance components and heritability of different longevity measures related to productive life and survival at a specified age, using linear and threshold models, to specify the more appropriate measure to express longevity in Brazilian Holstein cows. Production and reproduction records of Holstein cows were collected from 1991 to 2010, for cows born betwe...

Though overall bank performance from July 2007 to December 2008 was the worst since at least the Great Depression, there is significant variation in the cross-section of stock returns of large banks across the world during that period. We use this variation to evaluate the importance of factors that have been discussed as having contributed to the poor performance of banks during the credit cri...

Meta-analysis is a standard statistical method used to combine the conclusions of individual studies that are related and the results of single study alone can not answered to deal with issues. The data are summarized by one or more outcome measure estimates along with their standard errors. The multivariate model and the variations between studies are not considered in most articles. Here we d...

This paper sheds some light on the problems associated with random effects gravity approaches. Arguments for the superiority of a fixed effects model are given both along intuitive and econometric lines based on a Hausman test.  2000 Elsevier Science S.A. All rights reserved.

This paper uses data drawn from the English Football League to model separate hazard rates for club managers for the 2001/2, 2002/3 and 2003/4 seasons. On average over the three seasons, approximately one-third of managers involuntarily exited employment status with their club. We model the hazard using a standard logistic model exploiting information on the spell at risk rather than the indivi...

The aim of this paper is to propose a robust reliable bi-objective supply chain network design (SCND) model that is capable of controlling different kinds of uncertainties, concurrently. In this regard, stochastic bi-level scenario based programming approach which is used to model various scenarios related to strike of disruptions. The well-known method helps to overcome adverse effects of disr...

To take full advantage of global features of source images, we propose an image fusion method based on adaptive unit-linking pulse coupled neural networks (ULPCNNs) in the contourlet domain. Considering that each high-frequency subband after the contourlet decomposition has rich directional information, we employ directional contrast of each coefficient as the external stimulus to inspire each ...
