We report results from a corruption experiment with Indonesian public servants and Indonesian students. Our results suggest that the Indonesian public servant subjects have a significantly lower tolerance of corruption than the Indonesian students. We find no evidence that this is due to a selection effect. The reasons given by the subjects for their behaviour suggest that the differences in be...

Most data for evaluating and training recommender systems is subject to selection biases, either through self-selection by the users or through the actions of the recommendation system itself. In this paper, we provide a principled approach to handling selection biases, adapting models and estimation techniques from causal inference. The approach leads to unbiased performance estimators despite...

| A critical component of spline smoothing is the choice of knots, especially for curves with varying shapes and frequencies in its domain. We consider a two-stage knot selection scheme for adaptively tting splines to data subject to noise. A potential set of knots is chosen based on information from certain wavelet decompositions with the intention to place more points where the curve shows ra...

the aim of this study was to design the base breeding plan in sistani cattle by using of stochastic simulation. for this purpose, three population size (500, 1000, 2000 heads), three levels of herd number (5, 10, 20), two levels of selection intensity (high and low) and two levels of mating method (random and minimum co-ancestry) were combined together and in total 36 scenarios were compared fo...

Longitudinal atlas construction is a challenging task in medical image analysis. Given a set of longitudinal images of different subjects, the task is how to construct the unbias longitudinal atlas sequence reflecting the anatomical changes over time. In this paper, a novel longitudinal atlas construction framework is proposed. The main contributions of the proposed method lie in the following ...

We propose a method by which the intensity of purifying selection on a functional protein-coding gene is estimated by using three aligned homologous sequences: a processed pseudogene (psi), a functional paralog from the same species (g), and a functional ortholog from a different species (o). For each such trio, we calculate the numbers of nucleotide substitutions along the branches leading to ...
