The Power of Professional Expertise: Unravelling the Boardroom Diversity Puzzle Through a Machine Learning Approach

open access: yesAccounting &Finance, Volume 66, Issue 2, Page 1571-1593, June 2026.
ABSTRACT This study examines how board expertise diversity influences firm performance using a novel machine learning approach to classify directors' professional backgrounds. Drawing on data from Spanish listed firms, we develop multidimensional expertise profiles that capture multiple skills held by each director.

Political Cycles, Electricity Policy, and Mexico's Economy

open access: yesLatin American Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

The Lack of a COPII Cargo Receptor Erv14 Impacts Physiological Functions of the Vacuole in Saccharomyces cerevisiae

open access: yesTraffic, Volume 27, Issue 2, June 2026.
Loss of the cargo receptor Erv14 in Saccharomyces cerevisiae results in sensitivity to calcium, zinc, neutral extracellular pH, and elevated temperature. Furthermore, cells deleted in the ERV14 exhibits vacuolar fragmentation, enlarged lipid droplets, and metabolic alterations. Ruiz Salas, J. L. (2026) https://BioRender.com/b65g523. ABSTRACT Erv14 is a

Physicochemical and Thermal Evaluation of a Mixed‐Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.)

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...

Ni Microspheres as Electrocatalysts for Ethanol Oxidation in an Alkaline Medium

open access: yesInternational Journal of Electrochemical Science, 2018
We report the synthesis of nickel microspheres and their structural and electrochemical characterization. The materials were prepared by the microemulsion technique from NiSO4∙6H2O and NaOH, and using NaH2PO2∙H2O as a reducing agent.

Short‐term effects of wildlife rehabilitation disappear over time in the wild: A case study on Spanish imperial eagles

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
We assessed the effectiveness of Wildlife Recovery Centers by comparing dispersal behavior of rehabilitated and wild Spanish imperial eagles using GPS tracking. Rehabilitated individuals initially moved shorter distances, rested more, and hunted less than wild controls, but these differences declined over time and ultimately disappeared.
