The Russian Invasion of Ukraine from the Infotainment Perspective: Analysis of the Coverage by Spanish Television
(Blanquerna Ramon Llull University, 2025-11-04) Rosique-Cedillo, Gloria; Crisóstomo-Flores, Paz
This study examines the role of public television in the news coverage of armed conflicts and its possible relationship with infotainment. The research involved a content analysis of news broadcasts aired by La 1 of Televisión Española (TVE) during the first year of the Russian invasion of Ukraine, considering variables such as the type of appeal (emotional or rational), information sources, spectacularization techniques, and on-screen captions, among others. Although the news largely maintained an informational focus and a rational appeal consis­tent with hard news —providing context and explaining the causes and/or consequences of the conflict— it also borrowed certain technical elements from infotainment, primarily applied to visuals and language. The findings of this study suggest that La 1 should avoid the use of spectacularization as a strategy to maintain audience interest, as well as biased propagandistic framing, in order to present socially relevant issues from a deontological perspective and in adherence to the principles of journalistic quality. This aligns with one of the essential functions of public media: to uphold the constitutional right to information. El estudio aborda el papel que juega la televisión pública en la cobertura informativa de los conflictos bélicos y su posible relación con el infoentretenimiento. Para la investigación se realizó un análisis de contenido de las noticias que La 1 de Televisión Española (TVE) emitió durante el primer año de la invasión rusa de Ucrania, en el que se consideraron variables como: la apelación (emocional o racional), las fuentes informativas, los recursos de espectacularización y los rótulos, entre otras. Si bien las noticias conservan un enfoque prioritariamente informativo y con apelación racional conforme a las hard news, contextualizan y exponen las causas y/o las consecuencias del conflicto, éstas toman prestados algunos recursos técnicos del infoentretenimiento aplicados principalmente a las imágenes y al lenguaje. Los hallazgos de esta investigación permiten concluir que La 1 debe evitar el uso de la espectacularización como estrategia para mantener el interés del público, así como el tratamiento propagandístico sesgado de la información, a fin de presentar los asuntos relevantes que afectan a la sociedad desde una vertiente deontológica y apegada a los principios de calidad periodística, siendo una de las funciones esenciales de los medios públicos el satisfacer el derecho constitucional a la información.

Forecasting Electric Power Generation in a Photovoltaic Power Systems for Smart Energy Management
(Institute of Electrical and Electronics Engineers (IEEE), 2022-08-25) Rao, Challa Krishna; Sahoo, Sarat Kumar; Yanine, Fernando
Solar electricity is generated using photovoltaic (PV) systems all over the world. Solar power sources are irregular in nature since PV system output power is intermittent and highly dependent on environmental conditions. Irradiance, humidity, PV surface temperature, and wind speed are only a few of these variables. The uncertainty in photovoltaic generating, it's crucial to plan ahead for solar power generation. Solar power forecasting is required for electric grid supply and demand planning. Because solar power generation is weather-dependent and unregulated, this forecast is complicated and difficult. Selective developed to this goal. Traditional approaches such as statistics, autoregressive moving average, regression, and others were used to forecast PV power before the widespread usage variables are assessed for prediction models based on Artificial Neural Networks (ANN) and regression models. Several PV forecasting algorithms have been of machine learning technologies. Artificial Neural Networks, Support Vector Machines, and hybrid techniques have grown popular as a result of recent advances in machine learning methodologies and access to huge data. This study examines the impacts of numerous environmental conditions on PV system output, as well as the working principle and application of various PV forecasting approaches, in order to better comprehend the insights of PV prediction. Furthermore, the important parameters influencing PV generation are calculated using real-time data.

Formación integral para la sostenibilidad alimentaria: una asignatura pendiente en Latinoamérica
(Sociedad Chilena de Nutrición, Bromatología y Toxicología, 2025-10-31) Rincón-Cervera, Miguel Ángel; López-Arana, Sandra; Martínez-Galán, Julián Paul
La sostenibilidad constituye un eje estratégico para abordar los desafíos relacionados con los sistemas alimentarios a nivel local, nacional, regional y global. Fenómenos como la sindemia global y la triple crisis planetaria representan actualmente serias amenazas para los sistemas alimentarios, y en este escenario, la implementación de prácticas sostenibles y el uso de nuevas tecnologías para garantizar una alimentación adecuada sin comprometer los recursos y el bienestar de las futuras generaciones es de vital importancia. En Latinoamérica, las universidades deben liderar la formación de talento humano interdisciplinario mediante programas de Magíster accesibles y con un enfoque integral, que promuevan la articulación entre la academia, la industria, la sociedad y las instituciones de gobierno para avanzar en el cumplimiento de los Objetivos de Desarrollo Sostenible de la Agenda 2030. Sustainability is a strategic focus for addressing challenges related to food systems at the local, national, regional, and global levels. Phenomena such as the global syndemic and the triple planetary crisis currently pose serious threats to food systems. In this scenario, the implementation of sustainable practices and the use of new technologies to ensure adequate nutrition without compromising resources and the well-being of future generations is of vital importance. In Latin America, universities must lead the training of interdisciplinary human capital through accessible Master’s programs with a comprehensive approach that promote coordination between academia, industry, society, and government institutions to advance the fulfillment of the Sustainable Development Goals of the 2030 Agenda.

Respiratory effects of trunk inclination in obese and non-obese patients mechanically ventilated for ARDS
(BMC, 2025) Benites, Martín Hernán; Bihari, Shailesh; Battiato, Romina; Bruhn, Alejandro; Bugedo, Guillermo; Costa, Eduardo L. V.; Dellamonica, Jean; Guérin, Claude; Langer, Thomas; Marini, John J.; Marrazo, Francesco; Mezidi, Mehdi; Selickman, John; Wiersema, Ubbo F.; Retamal, Jaime
Background Adjusting trunk inclination in patients with acute respiratory distress syndrome directly affects physiological variables such as respiratory mechanics and PaCO2 levels. These effects may vary according to the body mass index (BMI) due to differences in lung and chest wall mechanics, highlighting the need for further investigation to clarify the clinical relevance of body position across patient subgroups. Methods A secondary analysis compared the physiological effects of increasing trunk inclination angles between mechanically ventilated patients with obesity (BMI ≥ 30 kg/m2) and those without obesity (BMI < 30 kg/m2). Results Data from 159 patients collected across seven individual studies were analyzed. The following physiological changes were observed in response to increased trunk inclination: Sixty-five patients with obesity presented a greater decrease in respiratory system compliance (-7.5 [-10; -5] mL/cmH2O; p < 0.001) compared to ninety-four patients without obesity (-3.5 [-7; -0.08] mL/cmH2O; p = 0.045). Lung compliance decreased in obese patients (-7.8 [-12.4; -3.3] mL/cmH2O; p < 0.001), whereas no significant changes were observed in patients without obesity (-5.9 [-14.2; 2.3] mL/cmH2O; p = 0.160). Chest wall compliance decreased by -42.9 [-63.2; -22.6] mL/cmH2O (p < 0.001) in obese patients and by -47.7 [-95.3; -0.15] mL/cmH2O in non-obese patients (p = 0.049). PaCO2 increased in obese patients by 4.6 [1.4; 7.8] mmHg (p = 0.004) but not in patients without obesity (2.5 [-0.6; 5.6] (p = 0.113). No significant differences were observed in PaO2/FIO2 between phases.
