This paper utilizes the Islamic holy month of Ramadan, a period of religious fasting, as a natural experiment to identify the effects of in utero nutrition on the labor market behavior of children in Indonesia when they become adults. Approximately seventy five percent of all pregnancies overlap with Ramadan, suggesting that in 2010 alone, more than 1.2 billion Muslims globally and 155 million ...

This paper proposes a novel scheme for digital images inpainting based on discrete wavelet transform (DWT). Where the digital image is decomposed into four components and both structure and exemplar inpainting methods are individually applied on them to obtain the best arrangement with each component. Many cases if digital image have been used to verify the scheme. The aim of this research is t...

The Distribution of Top Incomes in Five Anglo-Saxon Countries over the Twentieth Century Taxation data have been used to create long-run series for the distribution of top incomes in quite a number of countries. Most of these studies have focused on the national experience of individual countries, but we can also learn from cross-country comparisons. Comparative analysis is therefore the next s...

Neighborhood built environment characteristics may encourage physical activity, but previous literature on the topic has been critiqued for its reliance on cross-sectional data. In this issue of the Journal, Knuiman et al. (Am J Epidemiol. 2014;180(5):453–461) present longitudinal analyses of built environment characteristics as predictors of neighborhood transportation walking. We take this op...

Subjective and Objective video quality evaluation are important problems in video processing. This work describes some new guidelines for easy and reliable determination of quality metrics that are subjectively meaningful. ‘Mean Time Between Failures’ (MTBF) and ‘Probability of Failure’ (PFAIL) are introduced as new subjective quality metrics based on failure statistics, where failure refers to...

Returns to Education and Macroeconomic Shocks: Evidence from Argentina Returns to schooling in urban Argentina increased from 1992 to 2003, a period of economic reforms and macroeconomic volatility. In this paper I provide the most consistent estimates of returns to education so far, while I also investigate earnings profiles over time. This paper contributes to the existing literature by emplo...

This paper advocates a novel method for modelling physically realistic flow from captured incompressible gas sequence via modal analysis in frequency-constrained subspace. Our analytical tool is uniquely founded upon empirical mode decomposition (EMD) and modal reduction for fluids, which are seamlessly integrated towards a powerful, style-controllable flow modelling approach. We first extend E...

In this paper, I study the timing of high school dropout decisions using data from High School and Beyond. I propose a Bayesian proportional hazard analysis framework that takes into account the specification of piecewise constant baseline hazard, the time-varying covariate of dropout eligibility, and individual, school, and state level random effects in the dropout hazard. I find that students...

This paper complements existing power analysis tools by offering tools to compute minimum detectable effect sizes (MDES) for existing studies and to estimate minimum required sample sizes (MRSS) for studies under design. The tools that accompany this paper support estimates of MDES or MSSR for 21 different study designs that include 14 random assignment designs (6 designs in which individuals a...
