Detection of trending topic communities: Bridging content creators and distributors
No full textThe rise of a trending topic on Twitter or Facebook leads to the temporal emergence of a set of users currently interested in that topic. Given the temporary nature of the links between these users, being able to dynamically identify communities of users related to this trending topic would allow for a rapid spread of information. Indeed, individual users inside a community might receive recommendations of content generated by the other users, or the community as a whole could receive group recommendations, with new content related to that trending topic. In this paper, we tackle this challenge, by identifying coherent topic-dependent user groups, linking those who generate the content (creators) and those who spread this content, e.g., by retweeting/reposting it (distributors). This is a novel problem on group-to-group interactions in the context of recommender systems. Analysis on real-world Twitter data compare our proposal with a baseline approach that considers the retweeting activity, and validate it with standard metrics. Results show the effectiveness of our approach to identify communities interested in a topic where each includes content creators and content distributors, facilitating users' interactions and the spread of new information

Rezension: "Besuch in der Hölle. Dantes Göttliche Komödie. Biographie eines Jahrtausendbuchs" von Franziska Meier
No full textFranziska Meiers vorliegende Studie stellt einen wichtigen Beitrag zur aktuellen wissenschaftlichen Erforschung von Dantes Divina Commedia dar. In ihrer Untersuchung erläutert sie nicht nur die grundlegenden Kontexte der Entstehungsgeschichte und die Biografie des schon zu Lebzeiten umstrittenen Verfassers. Vielmehr gelingt es Meier, auch linguistische Aspekte, Fragen der Übersetzung und der Rezeption außerhalb Europas schlüssig darzustellen. Die Autorin und Übersetzerin Lorena Pircher, selbst auch Romanistin, hat diese Studie für die Medienimpulse rezensiert.Franziska Meier\u27s study represents an important contribution to current scholarly research on Dante\u27s Divina Commedia. In her new book, she not only explains the fundamental contexts of the genesis of the Commedia and biography of the author, who was already controversial during his lifetime. Rather, Meier also succeeds in coherently presenting linguistic aspects, questions of translation and reception outside Europe. The author and translator Lorena Pircher, herself also a Romance scholar, reviewed this study for Medienimpulse
A Social Framework for Set Recommendation in Group Recommender Systems
No full textThis research article presents a study about the background in Group Recommender Systems and how social factors are directly related to these applications. Some important group recommender systems in academia are described to exemplify their contribution in different domains. Besides, a framework that is intended to improve group recommender systems is proposed. The main idea of the framework is to enhance social cognition to help the group members agree and make a decision. Its structure includes a process where an influential group is detected among the target groups of people to recommend to. Social influence detection uses the knowledge behind online social connections and interactions. Trying to understand human behavior and ties among groups in a social network and how to use this to improve group recommender systems is considered the main challenge for future research. Combining this with the kind of item recommendation which involves a temporal sequence of ordered elements will present a novel and original path in Group Recommender Systems design
Argentine political leaders on Twitter: A study about the midterm elections in 2017
No full textEl uso de las redes sociales en las campañas electorales marca el pulso de lasestrategias actuales de la comunicación política. La conversación virtual de loscandidatos promueve definiciones de los problemas públicos que pretenden operar sobre la actitud hacia el voto de los ciudadanos. El presente estudio analiza el uso de Twitter por parte de las principales líderes políticas argentinas durante la campaña de las elecciones legislativas de medio término de 2017. Específicamente, se pretende investigar cuáles fueron los temas promovidos porlas lideresas, qué tipo de interacción mantuvieron con los medios "tradicionales" y qué diálogos establecieron con los ciudadanos. Los resultados demuestran que las conversaciones en Twitter se centraron en las consignas de campaña, incluyeron información ligada a la dimensión local y no abundaron en temáticas relacionadas al género. En un contexto en que los temas ligados a la mujer cobraron relevancia en las agendas política, mediática y pública, este trabajo pretende ir más allá del uso político de Twitter para identificar rasgos particulares de la construcción del liderazgo femenino en las redes sociales en contextos electorales.The use of Online Social Networks (OSNs) in electoral campaigns is no longer an option for candidates and their campaign teams. Their performance in the virtual public sphere will mark substantial differences at the time of vote. Indeed, although the presence of politicians in social media does not guarantee their victory in elections, it is unthinkable to build their public profile outside of them. The present study intends to analyze the use of Twitter by the main female Argentinian political leaders during the campaign of the mid-term legislative elections in Argentina in 2017. Specifically, it is intended to investigate which were the topics promoted by these leaders in the public virtual sphere and what kind of dialogues they established with citizens and between them. Likewise, based on their interaction in social networks, an attempt will be made to identify which leadership characteristics these candidates possess. Finally, the aim is to analyze the influence of the gender variable on its narratives. Results show that the conversations focused on campaign slogans, they included information linked to the local dimension and did not abound on gender-related issues. In a context where issues related to women became relevant in the political, media and public agendas, this work aims to go beyond the political use of Twitter to identify particular features of the construction of female leadership in social networks.Fil: Zunino, Esteban.

Estudio comparativo entre juegos de dimensiones estándar y juegos de dimensiones aumentadas para comprobar su repercusión en la cognición y la satisfacción al utilizarlo en el tiempo libre en adultos mayores de 75 a 85 años en el hogar geriátrico “PLENITUD, CIUDAD DE LA ALEGRÍA" por el periodo Septiembre 2019 - Febrero 2020
No full textLa presente investigación consistió, en la aplicación de juegos de dimensiones aumentadas y de dimensiones estándar en adultos mayores del Geriátrico “Plenitud” que comprenden edades entre 75 y 85 años con la finalidad de realizar un estudio comparativo en dichos juegos y establecer su repercusión en la cognición y satisfacción. Para tal efecto, se utilizó un diseño descriptivo correlacional con una población de 30 participantes, los cuales fueron divididos en dos grupos de 15; se ejecutaron los juegos de dimensiones aumentadas en el primer grupo, y en el segundo grupo los juegos de dimensiones estándar, para verificar en cada uno de los grupos se trabajó bajo la modalidad de test y re test, y así determinar el impacto a nivel cognitivo con el Test de Mayo y satisfacción con la Encuesta de Satisfacción ; en donde los resultados fueron satisfactorios en la utilización de juegos de dimensiones aumentadas, ante lo cual los beneficiarios directos fueron los adultos mayores que pertenecen al Geriátrico “Plenitud”This research related to the application of enlarged dimension games and standard dimension games on elderly adults of 75 to 85 years of age in the "Plenitud" Geriatric Home in order to carry out a comparative study between said games and establish their impact on cognition and satisfaction. To this end, a descriptive correlational design was used, and a population of 30 participants was divided into two groups of 15; the first group implemented the enlarged dimension games, and the second group implemented the standard dimension games. A test and retest modality was used to verify each one of the groups and, in this way, determine the impact on a cognitive level with the May Test and on satisfaction with a Survey on Satisfaction. The results of the use of enlarged dimension games were satisfactory, and the elderly adults of the "Plenitud" Geriatric were the direct beneficiarie
