Moral Dramas as a Sustainable Communication Genre: An Analysis of its (Dys)Functionalities
(2025-09-01)Sustainable consumption should foster ethical deliberation among audiences to effectively address socio-environmental crises. However, studies on current sustainable communication approaches reveal their insufficiency in ... -
Mitigating Moral Emotions After Crises: A Reconceptualization of Organizational Responses
(2025-07-01)Crises evoke a broad palette of negative moral emotions. However, past research has almost exclusively investigated anger. Building on insights from constructivist and social-functionalist theories of emotions, this ... -
Debunking the speed-fidelity trade-off: Speeding-up large-scale energy models while keeping fidelity
(2025-07-01)Energy system models are essential for planning and supporting the energy transition. However, increasing temporal, spatial, and sectoral resolutions have led to large-scale linear programming (LP) models that are often ... -
Computational fluid dynamics analysis of conventional irrigation and the combination with adjuvant suction cannulas in human molars with isthmus communication
(2025-07-01)This study evaluated CFD key irrigation parameters (flow pattern, irrigant velocity, wall shear stress and apical pressure) of conventional irrigation with positive pressure side-vented (SV) needle and the combination of ... -
Enhancing keyphrase extraction from long scientific documents using graph embeddings
(2025-07-01)This study explores the integration of graph neural network (GNN) representations with pre-trained language models (PLMs) to enhance keyphrase extraction (KPE) from lengthy documents. We demonstrate that incorporating graph ... -
Support mechanisms for low-carbon hydrogen: The risks of segmenting a commodity market
(2025-07-01)Although the actual scope of the hydrogen sector is subject to great uncertainty, a global wave of support mechanisms for low-carbon hydrogen is being registered. In many cases, these schemes aim to bridge the gap between ... -
