    COMUNIDAD DIGITAL DE LAS AUTOLESIONES DE LOS MENORES EN TIKTOK. Aproximación metodológica cuantitativa y cualitativa
    (VisualCOM Scientific Publications, 2024-07) Martín Muñoz, Diego; Atauri Mezquida, David
    La Autolesión No Suicida (ANS) es un fenómeno en aumento en las redes sociales, que afecta en España, a una media del 30 % de los jóvenes. Por ello se presenta una metodología aplicada para la identificación y análisis de los contenidos creados por jóvenes en TikTok. Por una parte, a través de un estudio cuantitativo, se utiliza una API que recoge y clasifica el contenido multimedia a través de hashtags. Por otra parte, un análisis cualitativo que elabora un estudio sistémico de los mismos. De esta manera, se plantea como objetivo identificar los contenidos en TikTok relativos a las ANS y comprender sus códigos

    Increasing temperature and time in glasshouses increases honey bee activity and affects internal brood conditions
    (Elsevier, 2024-06) O'Connell, Darren; Baker, Bronte; Atauri Mezquida, David
    Honey bees are globally important pollinators, key to many aspects of ecosystem function and agricultural production. However they are facing an increasing array of stress factors. These stressors include exposure to pathogens and pesticides, agricultural intensification, and changes in climate, and likely contribute to colony dysfunction and colony losses. Here we use temperature-controlled glasshouse experiments to investigate the impact of a field-realistic temperature-range on honey bee colonies, including temperatures based on projections for near-future local conditions. We show that increased temperatures have a significant impact on honey bee worker activity, with increased worker movement in and out of colonies, particularly over 30 °C. In addition, increased glasshouse temperatures led to significantly higher brood (egg, larval and pupal cells) humidity. Finally, temperature had a more severe impact at the later end of the experiment than at the start (on worker movement and brood conditions), suggesting that colonies under stress (either due to exposure to thermal stress or glasshouse confinement) have more difficulty in manging thermoregulation. These results indicate the potential impact of higher temperatures on the healthy functioning of these important pollinators.
