Post-earnings-announcement drift (PEAD) refers to the tendency of a stock’s return to drift for several monthly following publications of earnings results (Sadka, 2006). Ball & Brown discovered this anomaly in 1968, where they argued that investors tend to underreact to the information content of earnings.

Introduction It is known that air pollution had adverse effects on the health of those exposed to it. There is a diverse mix of air pollutants and the most common pollutants in outdoor air include carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), ground level ozone and particulate matter (PM) (1). Outdoor air pollution is a mixture of gases and particulate matter (PM) of varying sizes and it is often difficult to isolate the source of the PM from all the possible sources of…

Research Question The program logic model long-term outcome is the change in behavior of the population to reduce the number of drivers under the influence.

feature vector, which is the basic idea Eigen faces methods. These methods require more training samples, and is entirely based on the statistical characteristics of the gray scale image. The Neural Networks can reduce resolution face image, the autocorrelation function of the local area, the local texture. Such methods also need more training samples, and in many applications, the number of samples is very limited. Elastic graph matching method defined in two-dimensional space in a normal face…
