The distributed lag effect of ambient particulate air pollution that can be attributed to all cause mortality in Kathmandu valley, Nepal is estimated through generalized linear model (GLM) and generalized additive model (GAM) with autoregressive count dependent variable. Models are based upon daily time series data on mortality collected from the leading hospitals and exposure collected from th...

Repeating list items leads to better recall when the repetitions are separated by several unique items than when they are presented successively; the spacing effect refers to improved recall for spaced versus successive repetition (lag > 0 vs. lag = 0); the lag effect refers to improved recall for long lags versus short lags. Previous demonstrations of the lag effect have utilized lists contain...

Based on the current serious inflation problem at home and abroad, this thesis uses the data of broad money supply and monthly price during 1998 to 2008 and makes an empirical study on Chinese inflation time lag. Through the estimation of the Polynomial Distributed Lags Model, the author concludes that: money supply’s change has significant time lag effect on price’s change, and the lag time is...

Stopping motion and the flash-lag effect

A continuously moving object typically is perceived to lead a flashed object in space when the two retinal images are physically aligned, a phenomenon known as the flashlag effect (1). Eagleman and Sejnowski (2) recently published data that they interpreted to disagree with a previous explanation of this phenomenon, the differential-latency hypothesis (3–7), and to support instead a postdiction...

This research quantifies the lag effects and vulnerabilities of temperature effects on cardiovascular disease in Changsha--a subtropical climate zone of China. A Poisson regression model within a distributed lag nonlinear models framework was used to examine the lag effects of cold- and heat-related CVD mortality. The lag effect for heat-related CVD mortality was just 0-3 days. In contrast, we ...

Abstract—In many cases, there are some time lag between the consumption of inputs and the production of outputs. This time lag effect should be considered in evaluating the performance of organizations. Recently, a couple of DEA models were developed for considering time lag effect in efficiency evaluation of research activities. Multi-periods input(MpI) and Multi-periods output(MpO) models are...

[naeini1] one of the biggest organizational challenges in deployment of strategies is the time lag between the cause-and-effect relations according to a lag between indicators of strategic objectives. with adding the time factor, the strategic objectives at different times have a causal relationship with each other. the causal relationships between strategic objectives are essential. in this pa...
