Two Two‐Tier Stochastic Frontier Replications

Journal of Applied Econometrics, EarlyView.
ABSTRACT We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools.

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Maternal depression across childhood and offspring young adult depression and anxiety: Testing adolescent emotion dynamics as transdiagnostic mechanisms

JCPP Advances, EarlyView.
Abstract Background Early exposure to maternal depression can increase risk for offspring mental health problems across the lifespan. Less is known about the transdiagnostic pathways through which maternal depression influences offspring mental health risk in young adulthood.

Childhood adversity and psychotic‐like experiences in adolescence: Investigating a pathway via disrupted pubertal and grey matter development

JCPP Advances, EarlyView.
Abstract Background Childhood adversity increases psychosis risk, but the biological mechanisms responsible remain elusive. A possible but underexplored pathway involves altered pubertal and grey matter (GM) development. Methods In youth from the Adolescent Brain Cognitive Development study (N = 3462), we investigated the effect of adversity at age 9 ...

Paranoia and social anxiety: Structural and temporal relationships across adolescence

JCPP Advances, EarlyView.
Abstract Background Social anxiety (SA) and paranoia (PA) are commonly experienced during adolescence, but the nature of their co‐development is largely unknown. Greater clarity could significantly advance our understanding of both conditions, and of their progression into serious mental illness. Methods Utilising the Neuroscience in Psychiatry Network

Long‐Term Blood Pressure Variability, Hippocampal Subfield Volume and Cognitive Decline: A Population‐Based Prospective MRI Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Long‐term blood pressure variability (BPV) is associated with cognitive decline, yet the underlying mechanisms have not been fully elucidated. Purpose To investigate the associations between long‐term BPV and hippocampal subfield volume and cognitive function and to assess the mediation effect of hippocampal subfield volume.
