Harvesting benefits: Exploring the effects of second‐best policies on enhancing soil organic carbon stocks in agriculture

American Journal of Agricultural Economics, EarlyView.
Abstract Agricultural subsidies can be an effective policy tool to enhance soil organic carbon sequestration. This paper assesses the effectiveness of a second‐best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon.

Product churn, tastes, and price indices

American Journal of Agricultural Economics, EarlyView.
Abstract Price indices commonly used to measure inflation do not account for the entry and exit of products nor for systemic changes in consumer preferences over time. Recent developments in the theory of price indices show that these issues have significant impacts on the growth of prices that consumers experience.

Randomized, single‐centre, double‐blinded repeated dose investigation of safety and tolerability of ocular administrations of a novel silica eye drop product in healthy volunteers

Acta Ophthalmologica, EarlyView.
Abstract Purpose Managing ocular diseases often requires frequent eye drop administration, which can challenge patient compliance. A long‐acting eye drop technology using an amorphous synthetic silica composite was developed to address this. Our study aimed to assess the safety and tolerability of the Silica Eye Drop platform in healthy volunteers over

Ultrasound, PET/CT or temporal artery biopsy for giant cell arteritis? A prospective diagnostic accuracy study (the GAME‐study)

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the diagnostic performance of ultrasound, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose positron emission tomography/computed tomography (2‐[18F]FDG PET/CT) and temporal artery biopsy (TAB) in giant cell arteritis (GCA). Methods This was a prospective single‐centre diagnostic accuracy study (ClinicalTrials.gov NCT05248906).

A tutorial for understanding SEM using R: Where do all the numbers come from?

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Structural equation modeling (SEM) is often seen as a complex and difficult method, especially for those who want to understand how the numbers in SEM software output are actually computed. Although many open‐source SEM tools are now available—especially in the R programming environment—looking into their source code to understand the ...
