Does Less Education Harm Health? Evidence From a Natural Experiment in a Developing Country

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We investigate the health outcome effects of a reduction in years of schooling in Egypt in 1988, a policy change that moves in the opposite direction in relation to the extant literature. We exploit this policy change as a natural experiment and employ a fuzzy regression discontinuity design to investigate a range of objectively measured ...

Deciphering the performance of different surface models for corneal topography

open access: yesOphthalmic and Physiological Optics, EarlyView.
Abstract Purpose To study the performance of different corneal surface models to be used for ray tracing. Models based on geometric surfaces and polynomial fits were compared and the differences discussed. Methods For this simulation study, five characteristic generic surface configurations were generated: (A) perfect biconic, (B) decentred biconic ...

Image of mathematics: A case study of two women's early mathematics experiences

open access: yesSchool Science and Mathematics, EarlyView.
Abstract People often view mathematics as abstract, cold, and irrelevant to real life, and their school experiences likely influence such views. In this case study, we investigated the mathematics experiences of two women who participated in an afterschool girls‐only STEM club 30 years ago when they were in fifth and sixth grades.

A mile high and an inch deep: Exploring ChatGPT as a mathematics curriculum development tool

open access: yesSchool Science and Mathematics, EarlyView.
Abstract Artificial Intelligence (AI) technology has issues, including inherent bias and inaccurate information, yet it has not stifled individuals' use of this technology in the mathematics classroom. Thus, we conducted a document analysis to investigate ChatGPT, a generative AI chatbot, constructing elementary mathematical tasks to determine how ...
