Astigmatic changes after Descemet membrane endothelial keratoplasty (DMEK) in decompensated penetrating keratoplasty grafts

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the surgery‐induced changes of astigmatism after Descemet membrane endothelial keratoplasty (DMEK) in eyes with failed previous penetrating keratoplasty (PK). Design Retrospective, interventional cohort study based on prospective DMEK database.

Examining associations between foundational and complex mathematics skills in people with Down syndrome and typically developing children

British Journal of Developmental Psychology, EarlyView.
Abstract Acquiring mathematical competence is essential to independent living. In this study, we investigated the mathematics profile in young people with Down syndrome (DS), and the relations between foundational and more complex mathematics skills.

“I can do math!”: A self‐regulated learning intervention to enhance math‐related motivational factors and performance in middle school

British Journal of Educational Psychology, EarlyView.
Abstract Introduction Self‐regulated learning (SRL) interventions have been widely recognized for their potential to enhance students' academic achievement; however, their effects on math‐related motivational constructs remain less explored. This study investigated the impact of an SRL intervention on multiple math‐related motivational factors (math ...

Beyond performance: Emotions before and after semi‐high‐stakes mathematics testing among school‐aged students

British Journal of Educational Psychology, EarlyView.
Abstract Background Previous research has shown that testing differs significantly from other classroom activities and is associated with heightened negative emotions and lower levels of positive emotions. However, relatively little is known about students' emotions surrounding testing, particularly in higher‐stakes assessment settings. Aims This study

Computing Skinning Weights via Convex Duality

Computer Graphics Forum, EarlyView.
We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Understanding Visitor Path Choice and Enhancing Wayfinding in Museums: A Critical Review of a Century of Research

Curator: The Museum Journal, EarlyView.
ABSTRACT The paths taken by visitors in museums influence what they see, do, learn, and experience. Poorly designed museums can lead to missed goals and opportunities. In this article, I critically review visitor studies published since the 1930s to evaluate explanations for visitor path choice in museums, namely, the location and attractiveness of ...

The Legacy of Policy Inaction in Climate‐Growth Models

International Economic Review, EarlyView.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

A Comparative Review of Specification Tests for Diffusion Models

International Statistical Review, EarlyView.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

A spectral analysis extension to DEMATEL for strategic leverage points identification

International Transactions in Operational Research, EarlyView.
Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...
