Data management in audiovisual business: Netflix as a case study
Big data has become an enormous asset for on-demand content distribution services, helping information supply and decision- making, regarding both the content of the database and suscribers to the database. In this article we describe and define big data and data management in a media company devoted to on-demand audiovisual content distribution: Netflix. This article suggests that big data is a prime strategy in media business and outlines the upcoming challenges that follow its global expansion
Accesibilidad web. La nueva era de las WCAG 2.1, la transición de las futuras WCAG 3.0.
Durante las últimas décadas se han realizado esfuerzos por parte de los diferentes sectores de la sociedad para eliminar las barreras tanto físicas como tecnológicas para que todos los ciudadanos se pudieran desenvolver en cualquier medio sin ningún tipo de restricción, independientemente de su discapacidad. La accesibilidad Web cobra especial importancia en este ámbito, ya que aporta soluciones para que cualquier usuario pueda acceder al contenido Web, cuando existe una limitación física o tecnológica. Ahora nos encontramos ante un momento de transición, donde las Web Content Accessibility Guidelines 2.1 (WCAG 2.1) cobran especial relevancia para adaptarse a las actuales necesidades tecnológicas como una nueva versión recomendada de accesibilidad Web. Este estudio aporta una propuesta de mejora en el método de análisis de accesibilidad Web basado en herramientas de evaluación automáticas que complementan la revisión manual del experto, facilitando la valoración de los resultados obtenidos.Universidad de Málaga.

Exploring WHO communication during the COVID 19 pandemic through the WHO website based on W3C guidelines: accessible for all?
Health crisis situations generate greater attention and dependence on reliable and truthful information from citizens, especially from those organisations that represent authority on the subject, such as the World Health Organization (WHO). In times of global pandemics such as COVID-19, the WHO message “health for all” takes on great communicative importance, especially from the point of view of the prevention of the disease and recommendations for action. Therefore, any communication must be understandable and accessible by all types of people, regardless of their technology, language, culture or disability (physical or mental), according to the World Wide Web Consortium (W3C), taking on special relevance for public health content. This study analysed whether the WHO is accessible in its digital version for all groups of citizens according to the widely accepted standards in the field of the Internet. The conclusion reached was that not all the information is accessible in accordance with the Web Content Accessibility Guidelines 2.1, which implies that there are groups that are, to some extent, left out, especially affecting the elderly. This study can contribute to the development of proposals and suggest ways in which to improve the accessibility of health content to groups especially vulnerable in this pandemic.This research has received funds from a Plan Propio of University of Malaga and UMA18-FEDERJA-148
Insights into Embryo Defenses of the Invasive Apple Snail Pomacea canaliculata: Egg Mass Ingestion Affects Rat Intestine Morphology and Growth
Background:The spread of the invasive snail Pomacea canaliculata is expanding the rat lungworm disease beyond its native range. Their toxic eggs have virtually no predators and unusual defenses including a neurotoxic lectin and a proteinase inhibitor, presumably advertised by a warning coloration. We explored the effect of egg perivitellin fluid (PVF) ingestion on the rat small intestine morphology and physiology.Methodology/Principal Findings:Through a combination of biochemical, histochemical, histopathological, scanning electron microscopy, cell culture and feeding experiments, we analyzed intestinal morphology, growth rate, hemaglutinating activity, cytotoxicity and cell proliferation after oral administration of PVF to rats. PVF adversely affects small intestine metabolism and morphology and consequently the standard growth rate, presumably by lectin-like proteins, as suggested by PVF hemaglutinating activity and its cytotoxic effect on Caco-2 cell culture. Short-term effects of ingested PVF were studied in growing rats. PVF-supplemented diet induced the appearance of shorter and wider villi as well as fused villi. This was associated with changes in glycoconjugate expression, increased cell proliferation at crypt base, and hypertrophic mucosal growth. This resulted in a decreased absorptive surface after 3 days of treatment and a diminished rat growth rate that reverted to normal after the fourth day of treatment. Longer exposure to PVF induced a time-dependent lengthening of the small intestine while switching to a control diet restored intestine length and morphology after 4 days.Conclusions/Significance:Ingestion of PVF rapidly limits the ability of potential predators to absorb nutrients by inducing large, reversible changes in intestinal morphology and growth rate. The occurrence of toxins that affect intestinal morphology and absorption is a strategy against predation not recognized among animals before. Remarkably, this defense is rather similar to the toxic effect of plant antipredator strategies. This defense mechanism may explain the near absence of predators of apple snail eggs.Instituto de Investigaciones Bioquímicas de La PlataFacultad de Ciencias Veterinaria
LGBTIQ+, conspiracy theories and narratives of support and hate online: from streets to screens
This paper was presented at the International Conference "Genders, Sexualities and Diversities" (Universidad de Huelva, April 19, 2023).
In this communication, we explore, through different case studies, how sometimes LGBTIQ+ people are supported in the contexts of various events, demonstrations, or mobilizations in the streets (as is the case of International LGBT+ Pride Day or Women's International Day). Other times LGBTIQ+ people are recipients of online hate speech or different conspiracy theories in other scenarios, for example, in films, series, videogames, etc. It is possible to find online narratives about LGBTIQ+ people in different social networks that go from the more positive pole (support, solidarity, or even outrage when LGTBI people are rejected or recipients of hate crime) to the more negative one (disseminating hate, fake news or conspiracy theories). These narratives take place in different contexts: from street to screens. The paper is part of the I+D+i Project titled "Conspiracy Theories and Hate Speech Online: Comparison of Patterns in Narratives and social networks about COVID-19, immigrants, refugees, and LGBTI people [NON-CONSPIRA-HATE!]", PID2021-123983OB-I00, funded by MCIN/AEI/10.13039/501100011033/ and by "ERDF A way of making Europe."

En esta comunicación exploramos, a través de diferentes estudios de caso, cómo en ocasiones se apoya a las personas LGTBIQ+ en el contexto de diversos eventos, manifestaciones o movilizaciones en las calles (como es el caso del Día Internacional del Orgullo LGTBQI+ o el Día Internacional de la Mujer). Otras veces las personas LGTBIQ+ son receptoras de discursos de odio online o se encuentran diferentes teorías de la conspiración sobre las mismas en otros escenarios, por ejemplo, en películas, series, videojuegos, etc. Igualmente, es posible encontrar narrativas en línea sobre personas LGTBIQ+ en diferentes redes sociales que van desde las más positivas (apoyo, solidaridad, o incluso indignación cuando las personas LGTBIQ+ son objeto de rechazo o de delitos de odio) a las más negativas (difusión de odio, fake news, desinformación o teorías de la conspiración). Estas narrativas tienen lugar en diferentes contextos: de la calle a las pantallas.

The Relationship between Binge Drinking and Binge Eating in Adolescence and Youth: A Systematic Review and Meta-Analysis
Adolescence and youth are critical periods in which alcohol consumption is usually initiated, especially in the form of binge drinking. In recent years, it is increasingly common to find adolescents and young people who also present binge behaviors towards unhealthy food with the aim of alleviating their anxiety (emotional eating) and/or because of impulsive personality. Despite the social and health relevance of this issue, it remains scarcely studied and more preventive research needs to be developed. Our meta-analysis study aimed to evaluate the relationship and co-occurrence of both binge behaviors during adolescence and young adulthood to clarify the link between binge drinking and eating. Selective literature search on different online databases was performed. We identified discrete but significant results regarding the direct association between binge drinking and binge eating in correlation coefficients and odds ratio. Future research should focus on the common psychological background and motives behind these problematic behaviors owing to their clinical implications for effective prevention and treatment
Análisis del burnout en la residencia de ancianos Rey Ardid de Belchite
Hoy en día, la presencia de riesgos psicosociales es constante en todos los trabajos, independientemente del sector de actividad, siendo el estrés laboral el más importante. Cuando el estrés se cronifica, puede dar lugar a la aparición de otros riesgos como es el caso del burnout, especialmente común en el sector sanitario. En este contexto, el objetivo de este Trabajo Fin de Grado, ha sido el estudio del síndrome de burnout en la residencia de ancianos Rey Ardid de Belchite. Para ello se llevó a cabo una revisión de la literatura previa sobre el tema, para posteriormente realizar un estudio empírico en la citada residencia
Morphology and histology of the uropygial gland in antarctic birds: relationship with their contact with the aquatic environment?
The uropygial gland is morphologically different in diverse bird species. This gland was macroscopically and microscopically examined in penguins, storm petrels and skuas. In all the studied species, the gland showed a connective tissue capsule and one papilla. A negative relationship was observed between the relative glandular mass and the body mass, being highest in petrels (small glands) and lowest in penguins (large glands). Birds that spend much time in water (penguins) have gland characteristics related to a continuous, but not stored, secretion, such as straight adenomers, the presence of abundant elastic fibres in the connective tissue and the absence of a primary storage chamber. Instead, birds that have less contact with water (storm petrels) have a gland with much more tortuous adenomers and a small primary storage chamber. The secretory cells showed a positive PAS reaction in all the glandular zones. Therefore, no differences could be seen between the sebaceous and glucogenic zones, as proposed in other birds. These results allow the conclusion that, in aquatic birds, there is no connection between the relative mass of the uropygial gland and the time in contact with water, though the differences found in the histological structure could be related to a different contact with the aquatic environment.Facultad de Ciencias Naturales y MuseoFacultad de Ciencias Veterinaria
Networks and Emotions in Cooperative Work: A Quasi-Experimental Study in University Nursing and Computer Engineering Students
University students establish networks that impact on their behavior. Social Network Analysis (SNA) allows us to analyze the reticular structures formed and find patterns of interaction between university students. The main objective of this study was to observe the impact of interdisciplinary collaborative work between nursing and computer engineering students on the collaboration and friendship networks, emotions and performance of the participants. It is a quasi-experimental descriptive study with pre- and post-intervention measurements. The contact networks analyzed showed an increase in density in the post-intervention period. The most central people in the network corresponded with those who considered positive emotions most in their academic environment, while the less central people coincided with those who highlighted negative emotions. Academic performance was only significantly associated in the collaboration network, between this and OutdegreeN. This study shows the impact of interdisciplinary activities on teaching methodologies and the repercussions of emotions on curricular activity.S
Closer to or further from the new normal? business approach through social media analysis
The outbreak of COVID-19 has led to radical change in all social and economic spheres and, even today, the scope
of the pandemic cannot be detailed. This unprecedent situation is challenging the global world but particularly for
business. The packages of measures internationally imposed as restrictions on commercial activity, isolation and
social distancing mean that business should face a transformation in order to survive in each stage of the crisis.
For this purpose, a content analysis with an initial dataset with 2,610 tweets of the most representative Spanish
entrepreneurial organizations was carried out in key periods of the pandemic. The findings highlight that there
are collective concerns with emotional burden in the business sector that encourage action despite confusion and
uncertainty. Generalized distrust of policies led business organizations to insist on innovation and adaptation as
the best tools to overcome the economic effect of the crisis.This work was supported by the Operative Programme FEDER Andalucía 2014-2020 under grant number UMA18-FEDERJA-148 (Junta de Andalucía/Universidad de Málaga) and Funding for Open Access Charge: Universidad de Málaga/CBU
