Improving the Finite Sample Estimation of Average Treatment Effects Using Double/Debiased Machine Learning With Propensity Score Calibration

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT Double/debiased machine learning (DML) uses for estimating an average treatment effect (ATE) a double‐robust score function that relies on the prediction of nuisance functions, such as the propensity score, which is the probability of treatment assignment given covariates.

A Joint Test of Unconfoundedness and Common Trends

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We introduce an overidentification test of two alternative assumptions to identify the average treatment effect on the treated in a two‐period panel data setting: unconfoundedness and common trends. Under unconfoundedness, treatment assignment and post‐treatment outcomes are independent, conditional on control variables and pre‐treatment ...

Identifying Peer Effects in Networks with Unobserved Effort and Isolated Students

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT Peer influence on effort devoted to some activity is often studied when effort is unobserved, and the researcher instead observes an outcome that combines effort with other shocks. For instance, in education, achievement measures such as GPA reflect both effort and idiosyncratic GPA shocks.

Bayesian Model Averaging in Causal Instrumental Variable Models

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT Instrumental variables are a popular tool to infer causal effects under unobserved confounding, but choosing suitable instruments is challenging in practice. We propose gIVBMA, a Bayesian model averaging procedure that addresses this challenge by averaging across different sets of instrumental variables and covariates in a structural equation ...

Performance Evaluation of a Premier Resolution HPLC System for Detecting Hemoglobin Constant Spring, Hemoglobin Paksé, and Coexisting α‐ and β‐Thalassemia Mutations

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This study compared Premier Resolution HPLC with Capillary Electrophoresis for detecting HbCS/Hb Paksé variants and coexisting thalassemia mutations. Premier Resolution HPLC demonstrated superior performance with 50% fewer false negative cases (11 vs. 22) compared to Capillary Electrophoresis, particularly in heterozygous cases.

Cyclothymic‐hypersensitive temperament in early adolescence: Longitudinal measurement invariance and associations with psychopathology over time

open access: yesJCPP Advances, EarlyView.
Abstract Background Cyclothymic‐Hypersensitive Temperament (CHT) is characterised by mood instability, interpersonal hypersensitivity, and emotional hyperreactivity, traits frequently observed in general population as well as clinical settings but often eluding strict diagnostic classifications.

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

open access: yesJCPP 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.

Weak Degeneracy of Planar Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT The weak degeneracy of a graph G $G$ is a numerical parameter that was recently introduced by the first two authors with the aim of understanding the power of greedy algorithms for graph coloring. Every d $d$‐degenerate graph is weakly d $d$‐degenerate, but the converse is not true in general (e.g., all connected d $d$‐regular graphs except ...

Spreading quality improvement in bronchiolitis care: A qualitative study of barriers and facilitators to de‐implementation efforts across Alberta′s healthcare settings

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background Low‐value care remains prevalent in bronchiolitis management despite evidence‐based guidelines. De‐implementation initiatives face unique challenges compared with traditional implementation efforts, particularly when spreading across diverse healthcare settings.

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy
