An ecological momentary assessment study assessing repetitive negative thinking as a predictor for psychopathology
No full textRepetitive negative thinking (RNT), an important transdiagnostic process, is commonly assessed using trait questionnaires. While these instruments ask respondents to estimate their general tendency towards RNT, ecological momentary assessment (EMA) allows to assess how much individuals actually engage in RNT in their daily lives. In a sample of N = 1,176 adolescents and young adults, we investigated whether average levels of RNT assessed via EMA predicted psychopathological symptoms. Adjusting for trait RNT measures and baseline scores on outcome measures, we found that average levels of RNT assessed via EMA significantly predicted higher depressive and anxiety symptoms as well as lower mental well-being at baseline, one-, three-, and twelve-month follow-up. Exploratory analyses of the association between temporal dynamics of RNT (e.g., RNT inertia) and psychopathological symptoms yielded inconsistent results. The high predictive power of average scores on the EMA-based RNT measure suggests that EMA is a promising tool for assessing RNT
Minimalistic bis-triarylpyridinium cations: effective antimicrobials against bacterial and fungal pathogens
No full textA series of twelve compounds from the family of 2,4,6-triarylpyridinium cations have been synthesized, chemically characterized (1H, 13C NMR, HRMS), and microbiologically evaluated (MIC determination against S. aureus, E. faecalis, E. coli, P. aeruginosa, and C. albicans). These compounds are quaternary ammonium cations (QACs), classified as either mono-QACs or bis-QACs. The mono-QACs are further divided into those with short (three-carbon) and long (twelve-carbon) pendant chains. An additional structural variable is the number of bromine atoms attached to the aromatic rings, ranging from zero to three. The major findings of this study are: (a) bis-QACs exhibit notably higher antimicrobial activity than mono-QACs; (b) an increased number of bromine atoms on the structure appears to diminish antimicrobial properties and (c) one of the compounds (1a) shows particularly promising properties as a broad spectrum antimicrobial, given its low MICs across all five pathogenic microorganisms studied. Preliminary assays with C. albicans show that 1a has a strong mitochondrial activity, causing a remarkable mitochondrial membrane depolarization in this organelle. Taken together, this study positions triarylpyridinium cations—previously unexplored as antimicrobials—as promising candidates for future drug development, especially in light of the growing concern over drug-resistant microorganisms

Analisis de la estratègia de difusión de los medios, según su sistema comunicativo, en los canales de WhatsApp el caso de: The New York times, Whasigton Post, Der Spiegel, Bild, El País y ABC
No full textTreball Final de Grau en Periodisme. Codi: PE0932. Curs: 2024/2025El objetivo de esta investigación es estudiar la estrategia de difusión que siguen los medios de comunicación según su sistema comunicativo a través de sus canales de WhatsApp. Se analiza con detalle la temática y la función de los mensajes difundidos por cada medio, los recursos multimedia y la interacción, las fuentes y el género de las publicaciones, así como también las reacciones del usuario a los mensajes en relación con el tema de estos. Para esta investigación se utiliza el análisis de contenido cuantitativo sobre los 2281 mensajes publicados por The New York Times, The Washington Post, Der Spiegel, Bild, El País y ABC durante el mes de febrero de 2025. Los datos revelan que la frecuencia de publicación es regular para los medios, The Washington Post, El País y ABC, pero destaca The New York Times por un numero de mensajes difundidos bastante mayor que el resto de los medios y por lo contrario, se distinguen los medios alemanes por la baja frecuencia de publicación. Por otro lado, se evidencia que el tema predominante en los canales de difusión de la prensa internacional es sucesos. También es relevante que los medios de manera general no fomentan la interacción con el usuario y que el uso de recursos se limita en gran parte a un enlace junto a una imagen por mensaje. Estos resultados aportan nuevos conocimientos sobre el uso de los canales de difusión de WhatsApp por parte de los medios de comunicación.The aim of this research is to study the dissemination strategy followed by the media according to their communication system through their WhatsApp channels. The subject matter and function of the messages disseminated by each medium, the multimedia resources and interaction, the sources and genre of the publications, as well as the user's reactions to the messages in relation to their subject matter are analysed in detail. This research uses quantitative content analysis on the 2245 messages published by The New York Times, The Washington Post, Der Spiegel, Bild, El País and ABC during the month of February 2025. The data reveal that the frequency of publication is regular for The Washington Post, El País and ABC, but The New York Times stands out for a much higher number of messages disseminated than the rest of the media, and the German media stands out for its low frequency of publication. On the other hand, it is evident that the predominant theme in the dissemination channels of the international press is events. It is also relevant that the media generally do not encourage interaction with the user and that the use of resources is largely limited to one link and one image per message. These results provide new insights into the use of WhatsApp broadcast channels by the media
The step-level public good aspect of equity crowdfunding: A game-theoretic analysis
No full textThe social significance of crowdfunding has been growing during the last few years and it has become an attractive and common way to finance different kinds of projects. In the particular case of an equity crowdfunding campaign, it implies an interesting social interaction among potential contributors (the “crowd”) since it can be conceptualized as the interaction in the private provision of a step-level public good whose rivalry and excludability are ruled by the equity principle. The present paper adopts this perspective to analyze for the first time the most basic rationale for the dynamics and results of such interaction applying a game-theoretic approach. The model assumes a two-period society in which a sufficiently high number of agents decide how much to contribute to an equity crowdfunding campaign seeking contributions to cover the investment needed by a project. If that target is relatively low, the collective behavior of the “crowd” results in an inefficient equilibrium, creating a reversed-social-dilemma among crowdfunders, the opposite of the social dilemma related to the common free-rider problem in the private provision of regular step-level public goods. If the target is not that low, the social interaction may lead to a multiplicity of equilibria, but in every possible equilibrium the amount collected by the campaign is exactly the needed investment.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: Universitat Jaume I; UJI-B2020-48.

La maternidad cambia la respuesta a feromonas masculinas: de atracción a agresión
No full textIntroducción: La maternidad produce cambios que ayudan a ejercer mejor el
cuidado de crías. En ratones, se reducen las interacciones sociales con adultos,
restringiéndose la vida social al cuidado de las crías. Además, las madres ata can a intrusos que se acerquen al nido. Esta agresión maternal es desencade nada por feromonas sexuales masculinas, que son atractivas para la hembra
durante otros períodos de su vida. Nuestro objetivo es entender las bases cere brales y sensoriales del cambio de atracción a agresión que comporta la mater nidad. Metodología: Para eso, expusimos hembras, vírgenes y madres, a viruta
ensuciada por machos o a viruta limpia. Posteriormente procesamos su cerebro
y órgano vomeronasal (VNO, responsable de la detección de feromonas) para
la detección inmunohistoquímica de cFos y pS6, cuya expresión es inducida por la
actividad neuronal. Así, combinamos el estudio de la conducta con el análisis de
la función de los circuitos cerebrales sociosexual, motivacional y quimiosensori ales y del VNO. Resultados, discusión y conclusiones: Los resultados sugi eren que la maternidad reduce la sensibilidad del VNO, las madres muestran
menor respuesta a feromonas aun teniendo el mismo tiempo de exploración de
los estímulos masculinos que las hembras vírgenes. En el SNC, la expresión de
cFos en los sistemas cerebrales estudiados indica que el patrón de actividad
inducido por feromonas masculinas en estos sistemas cambia bruscamente du rante la maternidad. Como conclusión, las hormonas de la gestación cambian la
función del VNO y del cerebro alterando la conducta social y haciéndola
maternal.Introduction: Motherhood produces changes that help to better care for off spring. In mice, social interactions with adults are reduced, restricting social life
to caring for pups. Additionally, mothers attack intruders who approach the nest.
This maternal aggression is triggered by male sex pheromones, which are at tractive to the female during other periods of her life. Our aim is to understand
the cerebral and sensory bases of the change from attraction to aggression that
motherhood entails. Methodology: For this, we exposed virgin females and
mothers to male-soiled bedding or to clean shavings. We subsequently proc essed their brain and vomeronasal organ (VNO, responsible for pheromone
detection) for the immunohistochemical detection of cFos and pS6, whose ex pression is induced by neuronal activity. Thus, we combine the study of behav iour with the analysis of the function of the sociosexual, motivational and chemo sensory brain circuits and the VNO. Results, Discussion and Conclusion: The
results suggest that motherhood reduces the sensitivity of the VNO, as mothers
show a lower response to pheromones even though they display the same ex ploration time for male stimuli than virgins. In the CNS, the expression of cFos
in the brain systems under study indicates that the pattern of activity induced by
male pheromones in these systems changes briskly during motherhood. In con clusion, gestation hormones change the function of the VNO and the brain, alter ing social behaviour and making it maternal
Adapting Semi-Supervised Segmentation methods to Multimodal Remote Sensing Data
No full textPonència presentada al 44th EARSeL Symposium, 26–29 May 2025, Prague, Czech RepublicRemote sensing (RS) imagery is important for applications ranging from land cover and land use (LCLU) mapping to agriculture and forest monitoring. However, there is a limited availability of high-quality labeled data to use as a reference to train supervised learning (SL) models. Semi-supervised learning (SSL) frameworks, such as UniMatch (Yang et al., 2023), use pseudo-labeling and consistency regularization methods to address this limitation. Similar works have been adapted to RS: LSST (Lu et al., 2022) refines pseudo-labels with adaptive class-specific thresholds, while RS-DWL (Huang et al., 2024) mitigates noise and class imbalance through decoupled learning and confidence-based weighting. Despite these advances, SSL applications to multimodal RS imagery remain underexplored. We address this gap by adapting the SSL framework UniMatch to incorporate diverse encoders and multimodal remote sensing data for LCLU segmentation. We experimented on FLAIR-2 (Garioud et al., 2023), a dataset that combines very high-resolution aerial imagery (RGB) with near-infrared (NIR) data and elevation measurements (above-ground height). Key findings reveal that we achieved the best segmentation results using a transformer encoder for SL and SSL scenarios. When comparing RGB-only data and multimodal data, we observed that some classes, like “buildings”, “water”, and “coniferous”, benefited from the inclusion of NIR and elevation information. In the semi-supervised experiments, where only half of the data was labeled, and the remaining half was used as unlabeled (simulating a real-world scenario), the multimodal SSL approach outperformed the fully supervised learning (FSL) approach using only the labeled subset (1/2). These results highlight the strong potential of data fusion in RS applications with limited labeled data
