A Test of the Coase Conjecture Using Prices of Electronic Books

Southern Economic Journal, EarlyView.
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.

Exposure to Structurally Related Organophosphate Esters Elicits Distinct Metabolomic Perturbations in Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Organophosphate esters (OPEs) are found ubiquitously in the environment and exposure to these chemicals has induced behavioral, developmental, and morphological impairments in several model organisms. Yet there is still a lack of understanding of how sub‐lethal exposure disrupts organism function at the molecular‐level, especially for Daphnia ...

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.
