Bayesian Inference for Joint Estimation Models Using Copulas to Handle Endogenous Regressors

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
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

Positive mixture effects in pine–oak forests during drought are context‐dependent

open access: yesPlant Biology, EarlyView.
Mixture effects in drought‐stressed pine‐oak forests are context‐dependent, with Gambel oak and ponderosa pine benefiting from their complementarity under semi‐arid conditions. Abstract The increasing severity and frequency of droughts will play a pivotal role in shaping future forest ecosystems worldwide.

Systemic risk in the insurance sector: A semi‐parametric approach based on Spearman's rho

open access: yesRisk Management and Insurance Review, EarlyView.
Abstract We propose a new method to measure systemic risk in the global insurance sector by analyzing interconnectedness among firms under different market conditions. Using a semi‐parametric approach that relies on the Spearman correlation and copula‐based partial dependence, we assess relationships in relatively stable, extremely bullish, and ...

Subcritical Cracking Associated With Subgrain Rotation Recrystallisation in Quartz Inferred From Cathodoluminescence Study

open access: yesTerra Nova, EarlyView.
ABSTRACT We employed cathodoluminescence (CL) to study deformed quartz phenocrysts from the Cretaceous granite porphyry in SW Japan and observed fracture‐like planar structures appearing as CL‐dark bands. These CL‐dark bands were aligned with low‐angle grain boundaries formed by subgrain rotation recrystallisation.

Drawing Animals in the Paleolithic: The Effect of Perspective and Abbreviation on Animal Recognition and Aesthetic Appreciation

open access: yesTopics in Cognitive Science, EarlyView.
Abstract The majority of Pleistocene figurative cave art in Western Europe consists of line drawings depicting large herbivores from the side view, and outlines were sometimes abbreviated to the head‐neck‐dorsal line. It is often assumed that the side view was used because it facilitates animal recognition compared to other views, and that abbreviated ...

Weak Nuclear Divergence Despite Pronounced Mitochondrial Divergence Within a Widespread Desert‐Inhabiting Palearctic Lark (Aves: Alaudidae)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT The Bar‐tailed Lark Ammomanes cinctura is a polytypic bird species with a wide distribution. One of its three subspecies, A. c. arenicolor, has previously been found to show deep mitochondrial divergence between its geographically most distant populations, from Morocco and Saudi Arabia, respectively.
