This study evaluates the employment impact of disability anti-discrimination laws in OECD countries. The study focuses on the varieties of these domestic laws from an international perspective, particularly the reasonable accommodation duty which is considered a critical factor regarding the...

Misclassification is found in many of the variables used in social sciences and, in practice, tends to be ignored in statistical analyses, and this can lead to biased results. This paper shows how to correct for differential misclassification in multilevel models and illustrates the extent to...

Group-level variance estimates of zero often arise when fitting multilevel or hierarchical linear models, especially when the number of groups is small. For situations where zero variances are implausible a priori, we propose a maximum penalized likelihood approach to avoid such boundary...

An additive multilevel item structure (AMIS) model with random residuals is proposed. The model includes multilevel latent regressions of item discrimination and item difficulty parameters on covariates at both item and item category levels with random residuals at both levels. The AMIS model is...

The built environment has been identified as one of the cost effective platforms for reducing energy demand and greenhouse gas emissions. With policies and the know-how in existence, the real estate sector has already adopted measures such as building codes and energy efficiency labels to drive...

The debate about whether Internet use increases or decreases subjective well-being is growing. However, previous studies rarely explore either this association at the time of financial crisis or the mechanisms by which contextual factors affect well-being. Using the four waves of the European...
