European Journal of Education, Volume 61, Issue 2, June 2026.ABSTRACT Structural equation modelling (SEM) has become a widely used method across various disciplines including educational leadership and management (EDLM). Although researchers in many disciplines have conducted reviews regarding the use of PLS‐SEM, its application in EDLM has not yet been reviewed comprehensively.

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.ABSTRACT Flooding is one of the most devastating natural disasters worldwide. It is also expected to become more severe as climate change impacts are realised. Two‐dimensional (2D) hydrodynamic models are used to obtain reliable inundation estimations.

LABOUR, Volume 40, Issue 2, Page 131-161, June 2026.ABSTRACT The present paper provides an overall framework to afford the problem of non‐representativeness and non‐random selectivity arising from online job ads data, using Generalized sample selection models and Eurostat benchmark data. We jointly model the outcome intensity (number of online job ads in observed profiles, whose levels are defined by ...

Testing Copula Hypothesis with Copula Entropy
Testing copula hypothesis is of fundamental importance in the applications of copula theory. In this paper we proposed a copula hypothesis testing with copula entropy. Since copula entropy is a unified theory in probability and therefore testing copula hypothesis based on it can be applied to any types of copula function.

Bayesian Inference for Joint Estimation Models Using Copulas to Handle Endogenous Regressors
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 3, Page 519-534, June 2026.ABSTRACT This study proposes a Bayesian approach for finite‐sample inference of the Gaussian copula endogeneity correction. Extant studies use frequentist inference, build on a priori computed estimates of marginal distributions of explanatory variables, and use bootstrapping to obtain standard errors. The proposed Bayesian approach facilitates precise

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Large‐scale vegetation restoration is reshaping belowground systems globally, yet root dynamics remain poorly quantified, limiting predictions of ecosystem resilience to hydroclimatic variability. Rooting depth reflects a trade‐off between carbon benefits and respiratory costs, but assessment is hampered by soil‐moisture uncertainty and weak ...
