Endocrinology, Diabetes &Metabolism, Volume 9, Issue 5, September 2026.In this population‐based study of 883 women, AMH declined less with age in women with PCOS than in healthy women. Higher AMH may protect older healthy women from T2DM but indicates elevated metabolic risk in younger women with PCOS, supporting its role as a life‐course biomarker for metabolic risk stratification.

Increasing Respiration Weakens the Carbon Sink Over Two Decades in a Temperate Deciduous Forest
Global Change Biology Communications, Volume 1, Issue 3, September 2026.Using a 20‐year eddy covariance record from a temperate deciduous forest, we show that net carbon uptake declined over two decades. Both the trend and interannual variability in net carbon exchange were respiration driven, with warming winters and increasing late‐summer diffuse light driving the trend in respiration.

Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters
The RAND Journal of Economics, Volume 57, Issue 3, Page 471-494, Autumn (Fall) 2026.ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

Mergers in the Presence of Adverse Selection
The RAND Journal of Economics, Volume 57, Issue 3, Page 495-514, Autumn (Fall) 2026.ABSTRACT In the presence of adverse selection, mergers can increase welfare through a reduction in inefficient sorting. I characterize the sorting externality internalized between merging firms in a tractable discrete choice model. Mergers benefit consumers when the firms are small, willingness to pay is moderately increasing in cost, and consumer ...

The Incidence of Coarse Certification: Evidence From the ENERGY STAR Program
The RAND Journal of Economics, Volume 57, Issue 3, Page 545-585, Autumn (Fall) 2026.ABSTRACT A coarse certification provides simple but incomplete information. Its rationale is to help consumers trade off dimensions of quality that are complex and lack salience. In imperfectly competitive markets, it may induce excess bunching at the certification requirement, crowd out quality, and facilitate price discrimination. Who will ultimately

British Journal of Educational Psychology, Volume 96, Issue 3, Page 1341-1361, September 2026.Abstract Background Research based on embodied cognition has demonstrated that physical posture, particularly an upright seated posture, can influence emotions and cognition. However, although students spend most of the day sitting in classrooms, intervention research on upright seated postures suitable for learning environments is limited.
