Psychometric Evaluation of the Emotion Regulation Questionnaire (ERQ) in Peruvian Psychology Undergraduates: Factor Structure, Reliability, and Measurement Invariance Across Sex

Evidence for the original adult Emotion Regulation Questionnaire (ERQ) in Peruvian university populations remains limited, particularly regarding score comparability across sex. This cross-sectional psychometric study evaluated the factor structure, internal consistency, and sex-...

Chemical–Sensory Trade-Offs in Honey-Sweetened CCN-51 Cacao Mucilage Beverages

Cacao mucilage is an underutilized cacao side stream with potential as an acidic base for value-added beverages. This study evaluated five minimally formulated CCN-51 mucilage beverages containing water and either honey or sucrose to determine whether formulations with the highes...

Agentic Artificial Intelligence in Chemical Engineering, Process Systems Engineering, and Process Control: A Systematic Review of Emerging Perspectives and Challenges

Agentic artificial intelligence is gaining significance in chemical engineering. Many process decisions involve coordinated actions rather than isolated predictions. These decisions are constrained by physical limitations, uncertain measurements, safety protocols, and human super...

Comparative Evaluation of Machine Learning Models for Global Horizontal Irradiance Estimation in an Arid Coastal Climate

Accurate estimation of global horizontal irradiance (GHI) is relevant for characterizing solar resources in regions with limited measurement infrastructure. This study compared six machine learning models Polynomial Ridge Regression, Decision Tree, Random Forest, XGBoost, Artific...

Characterization of the ecological impacts of prescribed fire in South America: a review

Prescribed fire has been shown to offer substantial benefits to both human populations and ecosystems, but it can also cause environmental harm, such as reduced air quality and negative impacts on sensitive species. To support the appropriate use of prescribed fire, stakeholders...

A micronova burst in the intermediate polar IGR J17014-4306

Abstract We report the detection of a short optical burst in TESS data of IGR J17014-4306, the eclipsing intermediate polar with the longest known orbital period. The burst lasts 1.56 d and shows multiple peaks, reaching (9.3 ± 0.2) × 1033 erg s−1, and releases a total energy of...

Perceived Organizational Support, Employee Resilience, and Sustainable Employability in Higher Education Institutions: A Cross-Sectional Latent Indirect-Effects Model

Higher education institutions must sustain employees’ capacity and motivation amid organizational change. This study examined cross-sectional associations among perceived organizational support (POS), employee resilience, and sustainable employability in 202 university employees...
