Age and growth of the spiny butterfly ray Gymnura altavela (Elasmobranchii, Gymnuridae) in the Southwest Atlantic (in situ) and under human care in a public aquarium (ex situ): Plasticity and population patterns

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study provides the first age and growth assessment of the endangered spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the Southwest Atlantic, while also updating the growth parameters (asymptotic disc width—DW∞ and growth coefficient—k) estimated in an ex situ a marine aquarium setting.

Individual differences in set‐shifting and levodopa responsiveness in Parkinson's disease

open access: yesJournal of Neuropsychology, EarlyView.
Abstract Perseveration (PE) and learned irrelevance (LI) are two distinct processes that shape attentional set‐shifting in Parkinson's disease (PD). Whether LI and PE are dopamine‐dependent remains unclear. We investigated whether PE and LI may be dissociated in early PD and whether these switch conditions are associated with an individual motor ...

When indemnity insurance fails: Parametric coverage under binding budget and risk constraints

open access: yesJournal of Risk and Insurance, EarlyView.
Abstract In high‐risk environments, traditional indemnity insurance is often unaffordable or ineffective, despite its well‐known optimality under expected utility. We compare excess‐of‐loss indemnity insurance with parametric insurance within a common mean‐variance framework, allowing for fixed costs, heterogeneous premium loadings, and binding budget ...

Treatment, Exposure, and Spatial Counterfactuals in Regional Policy Evaluation: A Framework for Impact Analysis With Spatial Spillovers

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT Regional policies often affect untreated but spatially exposed units, making standard difference‐in‐differences comparisons difficult to interpret. This paper develops a treatment‐exposure framework for regional policy evaluation with spatial exposure and interference.

The Coronally Advanced Flap: The Past, the Present, and the Future

open access: yesJournal of Periodontal Research, EarlyView.
The story of the coronally advanced flap is the story of periodontal evolution. What began as a predictable root‐coverage technique has become a comprehensive surgical philosophy—applicable to esthetic recession, regeneration, and implant rehabilitation. The future? Reconstructive bone surgery with less surgical burden for patients.
