El tractament periodístic sobre l'espai comunicatiu al País Valencià: Anàlisi de la cobertura mediàtica en la premsa escrita a propòsit de la fi de RTVV
No full textEl tancament de Radiotelevisió Valenciana (RTVV) el 2013, amb la fi definitiva de les emissions de Canal 9, representa un episodi de gran rellevància política, mediàtica i simbòlica en la història contemporània valenciana. L’estudi analitza la cobertura periodística que la premsa generalista va dedicar a aquest procés mitjançant un enfocament longitudinal i comparatiu, posant en relleu el paper actiu dels mitjans en la construcció simbòlica de la realitat. Basant-se en els postulats de la Teoria de l’Agenda Setting i de la sociologia constructivista dels mitjans, la investigació identifica patrons de cobertura, divergències editorials i mecanismes de construcció del relat que configuraren la percepció pública del tancament. A partir d’una base de dades pròpia, el treball ofereix una anàlisi descriptiva i interpretativa que contribueix a comprendre el significat polític i comunicatiu de l’esdeveniment, i advoca per mantenir viu el debat científic i social sobre la gestió i el futur dels mitjans públics valencians.The closure of Radiotelevisió Valenciana (RTVV) in 2013, with the definitive end of Canal 9's broadcasts, represents a politically, mediatically, and symbolically significant episode in contemporary Valencian history. The study analyzes the journalistic coverage that general-interest newspapers devoted to this process through a longitudinal and comparative approach, highlighting the active role of the media in the symbolic construction of reality. Based on the postulates of Agenda Setting Theory and constructivist media sociology, the research identifies coverage patterns, editorial divergences, and narrative construction mechanisms that shaped the public perception of the closure. Drawing on its own database, the work offers a descriptive and interpretive analysis that contributes to understanding the political and communicative significance of the event, and advocates for keeping the scientific and social debate about the management and future of Valencian public media alive.Programa de Doctorat en Ciències de la Comunicaci
Energy, exergy, economic, and environmental (4E) assessment of an experimental moderately-high-temperature heat pump for district heating and cooling networks
No full textDeveloping district heating and cooling networks (DHCNs) requires new heat pumps (HPs) technologies to improve energy efficiency and replace fossil fuel boilers. This study presents a novel R-1234ze(E) moderately-high-temperature HP integrated with a semi-hermetic reciprocating compressor and an internal heat exchanger (IHX) controlled by a solenoid bypass valve. The HP is evaluated in terms of energy, exergy, carbon footprint, and economic viability. Two main configurations are explored: (i) simultaneous heating and cooling for 4G (4th generation) district heating networks (DHNs) and district cooling networks (DCNs), and (ii) heat source from a 4G or 5G DHN to increase the evaporation temperature, reaching a maximum value of 48 °C at 85 °C condensing temperature (48 °C/85 °C). Six scenarios combine several evaporating and condensing temperatures, with and without the IHX. The experimental results show that the IHX improves the heating capacity from 4.8 % to 19.3 %. However, it has a limited effect on simultaneous heating and cooling efficiency. Scenarios 2 °C/45 °C and 30 °C/65 °C with IHX achieve the highest COP (4.31 and 4.92). Exergy analysis reveals more significant destruction in extreme operating conditions, varying the efficiency from 21.5 % (low suction temperature) to 10.5 % (high suction temperature), highlighting improvement possibilities mostly in the evaporator, compressor, and condenser. Heat source DHN scenarios involve higher equivalent CO2 emissions per MWh, especially when the condensing temperature is higher. Economic analysis proves viability for simultaneous heating and cooling in all scenarios, with an optimum payback period of 1.96 years. It occurs similarly for heat source DHN in selected cases (30 °C/65 °C, 30 °C/80 °C with IHX, and 48 °C/85 °C without IHX), with an optimum payback period of 3 years.Funding for open access charge: CRUE-Universitat Jaume
Relationship Between Dietary Patterns and Blood Pressure During Adolescence: A Longitudinal Analysis From Dados Study
No full textackground: Previous research in adults has suggested that healthy dietary patterns could be an effective strategy for blood pressure (BP) control. However, during adolescence, the scientific literature examining this relationship is scarce and controversial since inverse and null associations have been reported. Thus, the aim of our study was to analyze the relationship between the level of adherence to the Mediterranean diet (MD) and consumption of fresh fruits and vegetables at baseline with changes in BP over a two-year period during adolescence. Methods: The analyses included 197 adolescents (92 girls) aged 13.9 ± 0.3 years. Adherence to the MD and consumption of fresh fruits and vegetables were assessed using the KIDMED questionnaire and a food frequency questionnaire, respectively. BP values were measured using an automatic sphygmomanometer according to standardized procedures. Results: Adolescents with high adherence levels to the MD, and high consumption of vegetables (but not fruits) at baseline, showed smaller increases in diastolic BP changes over two years (percentage of reduction ranging from ~48% to ~88%, all p < 0.026). No significant relationships were identified in systolic BP over the two-year period. Conclusion: Our findings underscore the importance of promoting MD and vegetable consumption to reduce diastolic BP during adolescence, contributing to lowering future cardiovascular risk.This study is funded by the Spanish Ministry of Economy and Competitiveness, MINECO (DEP2013-45515-R) and by the University Jaume I of Castellon, UJI (P1 1A2015-05, UJI-B2018-40, and UJI-A2022-02.Funding for open access charge: CRUE-Universitat Jaume
Switching Response in Organic Electrochemical Transistors by Ionic Diffusion and Electronic Transport
No full textThe switching response in organic electrochemical transistors (OECT) is a basic effect in which a transient current occurs in response to a voltage perturbation. This phenomenon has an important impact on different aspects of the application of OECT, such as the equilibration times, the hysteresis dependence on scan rates, and the synaptic properties for neuromorphic applications. Here we establish a model that unites vertical ion diffusion and horizontal electronic transport for the analysis of the time-dependent current response of OECTs. We use a combination of tools consisting of a physical analytical model; advanced 2D drift-diffusion simulation; and the experimental measurement of a poly(3-hexylthiophene) (P3HT) OECT. We show the reduction of the general model to simple time-dependent equations for the average ionic/hole concentration inside the organic film, which produces a Bernards-Malliaras conservation equation coupled with a diffusion equation. We provide a basic classification of the transient response to a voltage pulse, and the correspondent hysteresis effects of the transfer curves. The shape of transients is basically related to the main control phenomenon, either the vertical diffusion of ions during doping and dedoping, or the equilibration of electronic current along the channel length.The work of Juan Bisquert was funded by the European Research Council (ERC) via Horizon Europe Advanced Grant, grant agreement no 101097688 ("PeroSpiker").

The Future of Logo Design: Considering Generative AI-Assisted Designs
No full textThe article explores the application of artificial intelligence (AI) in generative design, specifically in the creation of trademark logos, through an academic experience with industrial design students. The study explores AI’s role in enhancing creativity, productivity, and diversity during the conceptual design phase, while capturing students’ perspectives on the creative process. The methodology employed included a qualitative survey with open-ended questions to gather student opinions. Two practical exercises were conducted, one using traditional methods and the other AI, to design logos for fictitious brands. Results indicate that manual designs allow for greater expression of brand identity and emotional attachment, whereas AI-assisted designs offer rapid generation of numerous versions with a professional finish. Students identified key advantages of AI, including time optimization and support in generating new ideas. However, they highlighted limitations such as reduced control over final outcomes and difficulties in editing AI-generated designs. The findings suggest that AI, while lacking the personality and emotional depth of manual designs, can complement traditional methods when used strategically. This study emphasizes the potential of hybrid approaches combining human creativity with AI efficiency to achieve optimal outcomes. It also underscores the need for design education to integrate AI tools, preparing students for a rapidly evolving industry. The research contributes to discussions on balancing efficiency, creativity, and control in professional logo design, proposing strategies for human-AI collaboration in design processes
Spatiotemporal analysis of forest cover changes and climate dynamics in Castellón province
No full textTreball de Final de Màster Universitari Erasmus Mundus en Tecnologia Geoespacial (Pla de 2022). Codi: SJL042. Curs acadèmic 2024-2025Understanding forest cover change dynamics and its association with climatic conditions is crucial for sustainable environmental management. This research examined forest cover change in Castellón Province by using satellite-based remote sensing and machine learning classification during 2010-2024. The supervised classification methods—Random Forest (RF), Support Vector Machine (SVM), and Classification and Regression Tree (CART)—were applied on Landsat images using Google Earth Engine environment. In this study, spatiotemporal trends integrate Google Earth Engine (GEE), Python-based statistical analysis, and GIS mapping to identify the best classifier as well as reliable model. RF outperformed other classifiers. It proved maximum accuracy using different performance and evaluation metrics. Classification results indicated a significant forest cover loss, especially between 2015 and 2020 due to urbanization, land use change, and potential climatic disturbances. The dynamics of forest conversion have been explored using transition matrices. It helped in detecting overall loss of areas of forest along with appreciable changes to non-forest categories.
The areas of significant deforestation along with afforestation trends were also recognized using spatial maps. This puts focus on finding out the factors behind the degradation like climate change, with anthropogenic effects on land use changes. The time series analysis of NDVI trends and Climate variables (Temperature-2m, Land Surface Temperature (LST) and Precipitation) shows alarming trends in the study area. The climatic variables showed possible strong correlation between vegetation health and climate fluctuations. Pearson correlation analysis confirmed the positive relationship between NDVI and precipitation while demonstrating the negative relationship between temperature and land surface temperatures (LST). The integration of the use of machine learning, remote sensing, along with statistical analysis identifies key insight into data-driven reasoning and detailed analysis of the forest cover changes within a Mediterranean ecosystem. The findings can contribute to sustainable forest management approaches and climate adaptation strategies by providing valuable insights into forest loss patterns including climatic drivers. It can also contribute to regional-level programs about forest conservation, climate adaptive measures, along with sustainable land-use planning and land management using scientific evidence and data-driven knowledge of the province
Disentangling the structure, optical properties, and photoluminescence emissions of NiW1−xMoxO4 (x = 25, 50, and 75%) solid solutions: experimental and DFT studies
No full textSolid solutions, formed by combining two transition metal oxides with distinct properties, offer promising potential for optimizing functional characteristics that may be lacking in the parent materials. In this study, NiWO4 and NiMoO4 semiconductors and homogeneous NiW1−xMoxO4 (x = 25, 50, and 75%) solid solutions were successfully synthesized via a co-precipitation method followed by heat treatment, without any surfactants or toxic solvents. Using a combination of characterization techniques—including X-ray diffraction, Raman and infrared spectroscopy, X-ray fluorescence, diffuse reflectance spectroscopy, and photoluminescence (PL) spectroscopy—alongside density functional theory calculations, we elucidate the relationship between the structure, electronic properties, and PL emissions at the atomic level. Furthermore, we propose a relay mechanism in the conduction band, where an electron transport ladder through the Ni–O–W/Mo framework acts as a driving force to modulate PL emissions
La multimodalidad en la docencia internacional en inglés
No full textLa docencia en inglés se instaló en las universidades españolas en la primera década de este siglo y se ha consolidado en la mayoría de ellas, bien mediante programas completos en inglés, o bien mediante asignaturas impartidas en esta lengua . Esta práctica ha supuesto un esfuerzo por parte de los profesores de contenido para expresarse en inglés y ayudar a los estudiantes a entender sus explicaciones, lo que ha conllevado en muchos casos el apoyo en medios audiovisuales con un alto contenido multimodal: imágenes, expresión facial, gestos, énfasis, entre otros recursos . En este artículo presentamos algunos resultados de la investigación llevada a cabo por el grupo GRAPE (Group for Research on Academic and Professional English) de la Universitat Jaume I . Sus estudios se han centrado en el análisis de la multimodalidad en contextos EMI (Educación por Medio del Inglés) . Por una parte, el estudio de los constructos multimodales (‘multimodal ensembles’) en el discurso del profesorado ha servido para visualizar elementos no verbales que ayudan al profesor a comunicar y a los estudiantes a comprender mejor el contenido . Por otra parte, se han realizado estudios sobre herramientas como el Sistema de Gestión de Cursos (‘Course Management System’) Moodle, así como del uso de materiales audiovisuales en el aula, y el aprendizaje de nuevos géneros digitales como el de venta de productos (‘product pitches’) y de PechaKuchas . Estos estudios han servido para poner de manifiesto la importancia del análisis multimodal con el objetivo de diseñar programas de formación eficaces para estudiantes y profesorado que faciliten su integración en los planes de docencia internacional en inglés de las universidades españolas
Risk factor profile in child to parent violence (CPV): a gender analysis
No full textChild-to-parent violence (CPV) is one of the crimes that has increased most sharply in Spain in recent years. Few studies identify the predictive variables of CPV specifically with a judicial sample, taking gender differences into account and using a standardized instrument. Participants were 342 juveniles from the Juvenile Court of a Spanish province. The most powerful predictors were depressive states, emotional mismanagement, reiteration, and the combination of various risk factors. For boys, the greatest predictors were a depressed state, criminal recidivism, and a moderate risk of recidivism according to the Youth Level of Service/Case Management Inventory (YLS/CMI). For girls, the greatest predictors were conflicts between partners in the nuclear family and the total score in the YLS/CMI. It is therefore crucial to take the specific predictive factors into account in order to adjust the specific strategies to reduce risk
