Characterizing correlations in partial credit speech recognition scoring with beta-binomial distributions

JASA Express Letters
Partial credit scoring for speech recognition tasks can improve measurement precision. However, assessing the magnitude of this improvement with partial credit scoring is challenging because meaningful speech contains contextual cues, which create correlations between the probabilities of correctly identifying each token in a stimulus.

Collective Risk Taking in Adolescents and Young Adults: Adolescents Take More Risks When Deciding Collectively Than Alone

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Adolescents show a heightened propensity to take risks, relative to other age groups, especially in contexts involving peers. In the current study, we investigated whether peer contexts and age interact to promote collective risk taking, that is, when groups of peers decide to take a risk together.

Optimizing Lymph Node Staging in Gallbladder Cancer: A Cutoff of 11 Nodes for Accurate Staging and Improved Survival

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background Gallbladder cancer (GBC) is an aggressive malignancy in which lymph node (LN) status is a key prognostic factor. Adequate LN retrieval is essential for accurate nodal staging. This study aimed to identify an LN threshold that reduces false node‐negative (false N0) rates and to evaluate its association with overall survival (OS) as ...

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, EarlyView.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing
