Communication Habits

The scientific communication habits and practices of the new wave of Spanish researchers are analyzed based on the results of an international survey (2019). The results obtained from 100 participants support those previously obtained from interviews conducted between 2016 and 2018 in Spain under the Harbingers Project, and show similarities to and differences from those collected from the mentioned survey in other countries covered by the Project in its second phase. Spanish researchers have two contradictory faces: They are innovative in their perceptions but slightly less so in their practices regarding open access and the use of social media. However, these new attitudes and habits are motivated by a desire to promote their own work and gain recognition; In this sense, they are conservative. The competition in which they are immersed regarding the achievement of tenure and, therefore, the need to focus on their abilities that will be evaluated represent a limitation on enjoying the learning process and dedicating themselves to the practices of open science to which their generation is naturally prone. Resumen Se analizan los hábitos y prácticas de comunicación científica de la nueva ola de investigadores españoles a partir de los resultados de una encuesta de ámbito internacional (2019). Los resultados de un centenar de contribuciones confirman los obtenidos previamente en entrevistas realizadas entre 2016 y 2018 en España en el marco del Proyecto Harbingers, y ponen de manifiesto similitudes y diferencias con los resultados obtenidos de la encuesta mencionada en otros países cubiertos por el Proyecto en su segunda fase. Los investigadores españoles presentan dos caras contradictorias: Son innovadores en sus percepciones aunque no tanto en sus prácticas relativas al acceso abierto y al uso de las redes sociales. Sin embargo, sus actitudes y hábitos nuevos no son desinteresados, están motivados por promocionar el trabajo propio y conseguir el reconocimiento. En este sentido, se muestran conservadores. La competición en que se encuentran inmersos para conseguir un trabajo estable y, por tanto, la necesidad de focalizarse en los méritos que les van a ser evaluados les limita para poder disfrutar del proceso de aprendizaje y dedicarse a las prácticas de ciencia abierta a las que su generación se muestra proclive de forma natural.

Use Of Social Media

Analyzing the influence of social media on the learning process is no longer a novel idea; however, due to its importance for students and consequently for teachers, research continues to explore the pedagogical potential of social media. The main objective of the present study was to analyze the influence of teacher roles (guide or facilitator) on students’ social participation in Twitter and their perceived academic experience. The sample consisted of 525 future teachers, all of the Master’s degree students at Spain’s National Distance Education University (UNED). We used a mixed triangulation design, a theoretical model, quantitative methods (descriptive analysis and contrast of means) and qualitative methods (content analysis following the principles of grounded theory). Our results showed that the teacher’s role as a facilitator exerted a more positive influence on how students assessed their experience and on their participation on Twitter than the role as a guide. We conclude that the use of social media sites in education offers a motivating and satisfying framework that is not provided by other more traditional means such as forums, and that a role that facilitates independent learning is a better strategy when using social media in the classroom.El análisis de la influencia de las redes sociales en el proceso de aprendizaje ya no es una novedad. Sin embargo, debido a su importancia para el alumnado y en consecuencia para el profesorado, la literatura científica sigue prestando atención al potencial pedagógico de las redes sociales. El objetivo principal de esta investigación fue analizar la influencia del rol del profesorado (guía y facilitador) sobre la participación social en Twitter y la experiencia académica percibida de los estudiantes. La muestra estuvo formada por 525 futuros profesores, estudiantes de posgrado en la Universidad Nacional de Educación a Distancia. Se utilizó un diseño mixto de triangulación, un modelo teórico, una parte cuantitativa (análisis descriptivo y contraste sobre medias) y otra cualitativa (análisis de contenido, siguiendo los principios de la teoría fundamentada). Los resultados mostraron que el rol facilitador del profesor influye positivamente en la valoración de la experiencia por parte de los estudiantes y en la participación en Twitter, en mayor medida que el rol guía. Por un lado, se concluye que el uso de las redes sociales, en el ámbito educativo, proporciona un marco motivacional y de satisfacción que no lo aportan otros medios más tradicionales, como los foros, y, por otro, que un rol que facilita un proceso de aprendizaje independiente es mejor estrategia cuando hablamos de redes sociales en el aula.

Over Time

This study analyzes the use of social media sources by nine news outlets in Chile in regard to Covid-19. We identified the most frequently used types of sources, their evolution over time, and the differences between the various social media platforms used by the Chilean media during the pandemic. Specifically, we extracted 838,618 messages published by Chilean media on Facebook, Instagram, and Twitter between January and December 2020. An initial machine learning (MA) process was applied to automatically identify 168,250 messages that included keywords that link their content to Covid-19. Based on a list of 2,130 entities, another MA process was used to apply a set of rules based on the appearance of declarative verbs or common expressions used by the media when citing a source, and the use of colons or quotation marks to detect the presence of different types of sources in the news content. The results reveal that Chilean media outlets’ use of different voices on social media broadly favored political sources followed by health, citizen, academic-scientific, and economic ones. Although the hierarchy of the most important sources used to narrate the public health crisis tended to remain stable, there were nuances over time, and its variation depended on key historic milestones. An analysis of the use of sources by each platform revealed that Twitter was the least pluralist, giving space to a more restricted group of voices and intensifying the presence of political sources over the others, particularly citizen sources. Finally, our study revealed significant differences across media types in the use of political, health, and citizen sources, with television showing a greater presence than in other types of media. Resumen Se analiza el uso de fuentes en redes sociales de nueve medios de información de referencia en Chile frente al Covid-19. Se identificaron los tipos de fuentes más utilizados, su evolución en el tiempo, así como las diferencias encontradas entre distintas plataformas de redes sociales de los medios chilenos. Específicamente, se extrajeron 838.618 publicaciones de medios nacionales desde Facebook, Instagram y Twitter entre enero y diciembre de 2020. A ese corpus se aplicó un primer proceso de machine learning (MA) para filtrar automáticamente 168.250 publicaciones que incluían palabras claves que identifican su contenido con el Covid-19. A partir de una lista de 2.130 entidades, se utilizó otro proceso de MA para aplicar un conjunto de reglas basadas en la presencia de verbos declarativos o de expresiones comunes usadas por los medios cuando se cita a una entidad, así como el uso de dos puntos o de comillas, con el objeto de detectar distintos tipos de fuentes en el contenido informativo. Los resultados muestran que el uso que los medios chilenos dieron a distintas voces en sus redes sociales favoreció ampliamente a las fuentes políticas, seguidas por las fuentes de salud, y más desde lejos por las ciudadanas, académico-científicas y económicas. Aunque la jerarquía de las fuentes que se usó para narrar la crisis sanitaria tendió a mantenerse estable, tuvo matices a lo largo del tiempo y su variación dependió de los hitos que marcaron la historia del país. Al analizar el uso de fuentes según plataforma, se observa a Twitter como menos pluralista, dando espacio a un grupo más restringido de voces e intensificando la presencia de las fuentes políticas por sobre las demás; en especial, por sobre las ciudadanas. Finalmente, nuestro estudio reveló diferencias significativas en las fuentes utilizadas por publicaciones de origen televisivo, particularmente en el uso de fuentes políticas, de salud y ciudadanas, las cuales tuvieron una presencia mayor que en los demás tipos de medios

El binomio teléfonos móvil y RRSS en la adolescencia transciende lo tecnológico. Las prácticas de uso tan habituales en su vida cotidiana son ubicuas, pero relativamente invisibles para docentes y familias. Un conocimiento necesario para marcar una hoja de ruta en el diseño de propuestas educativas mediadas por tecnologías móviles. Mediante un estudio descriptivo longitudinal cuantitativo, se identifican niveles de uso y comportamiento con los teléfonos móviles en una muestra (N=645) escolar en ESO-Bachillerato, prestando especial atención a qué aplicaciones son las más empleadas, y el tiempo de uso en función del género y nivel educativo. Los resultados evidencian que el teléfono móvil no se percibe como un sistema de almacenamiento de información, se emplea con una finalidad comunicativa (RRSS) de las que se nutren las aplicaciones de edición de imagen (fotografía-vídeo) y consumo de audiovisuales (vídeos-música). En el segundo año de ESO hay un incremento de aplicaciones y de tiempo empleado frente al móvil. Las diferencias de género suponen brechas significativas en cuanto al uso de RRSS, y el valor de la imagen un punto axiomático en ello. Una praxis que evidencia las amenazas que suscita su empleo, y el reto de diseñar una alfabetización digital ambiciosa que contemple usos responsables de las RRSS, conocimiento sumo informado de los contenidos digitales y la introducción de escenarios comunicativos multimodales para crear y compartir. The association of mobile phones and social networks during adolescence surpasses technological considerations. These practices, while extremely common and ubiquitous in adolescents’ daily lives, are relatively invisible to teachers and families. It is, therefore, necessary to establish a roadmap in the design of educational proposals enhanced by mobile technologies. Through a quantitative longitudinal descriptive study, levels of use and behavior with mobile phones are identified in a sample (N=645) of Secondary School and Baccalaureate students. Special attention, which we disaggregate by gender and education level, is paid to the most commonly used apps and to time of use. Results show that the mobile phone is not only identified as an information storage system, but it is also used for a communicative purpose (social media) which is supported by image editing applications (photography-video) and audiovisual consumption (videos- music). In the second year of Secondary Education there is an increase in the use of apps and in the time spent using mobile phones. There are significant differences in relation to gender in the use of social media, being the value of the image an axiomatic point in this difference. Results show the threats inherent in the use of mobile phones and highlight the challenges when it comes to designing an ambitious praxis of digital literacy that contemplates responsible uses of social media, highly informed knowledge of digital content and the introduction of multimodal communication scenarios that favour sharing creative processes.

Use Of Social Media

Although we live in a global society, educators face many challenges in finding meaningful ways to connect students to people of other cultures. This paper offers a case study of a collaboration between teachers in the US and Turkey, where 7th grade students interacted with each other via online social media as a means to promote cultural understanding. In a close analysis of a single learning activity, we found that children had opportunities to share ideas informally through social media, using their digital voices to share meaning using online writing, posting of images and hyperlinks. This study found that students valued the opportunity to develop relationships with each other and generally engaged in sharing their common interests in Hollywood movies, actors, celebrities, videogames and television shows. However, not all teachers valued the use of popular culture as a means to find common ground. Indeed, teachers had widely differing perspectives of the value of this activity. Through informal communication about popular culture in a «Getting to Know You» activity, students themselves discovered that their common ground knowledge tended to be US-centric, as American students lacked access to Turkish popular culture. However, the learning activity enabled students themselves to recognize asymmetrical power dynamics that exist in global media culture. Si bien vivimos en una sociedad global, los educadores se enfrentan a numerosos desafíos a la hora de hallar formas significativas de conectar a los alumnos con gente de otras culturas. Este artículo muestra un caso práctico de colaboración entre profesores de los Estados Unidos y Turquía, en el que alumnos de séptimo grado interactuaron entre sí a través de las redes sociales con el fin de promover la comprensión cultural. Al analizar una única actividad de aprendizaje hallamos que los alumnos tenían la oportunidad de compartir ideas informalmente a través de las redes sociales, usando su voz digital para compartir significados mediante la escritura online, publicación de imágenes e hipervínculos. Este estudio halló que los alumnos valoraban la oportunidad de relacionarse entre sí y tendían a compartir su interés común en películas de Hollywood, actores, famosos, videojuegos y programas de televisión. Sin embargo, no todos los profesores valoraban el uso de la cultura popular como medio para la búsqueda de puntos en común. En efecto, los profesores tenían perspectivas muy distintas sobre el valor de esta actividad. Mediante la comunicación informal en torno a la cultura popular en una actividad de conocimiento mutuo, los propios alumnos descubrieron que sus conocimientos en común tendían a estar centrados en los Estados Unidos, en tanto en cuanto los alumnos americanos no tenían acceso a la cultura popular turca. Sin embargo, la actividad de aprendizaje permitió a los propios alumnos reconocer las dinámicas de poder asimétrico que existen en la cultura mediática global.

ABSTRACT Objective: The aim of this study was to evaluate the prevalence of peri-implant mucositis, as well as hygiene care around implants and the correlation between keratinized gingiva and probing depth around implants. Methods: The study consisted of 107 dental implants of 24 patients treated at Faculdade São Leopoldo Mandic who were evaluated for the presence of bleeding, presence of keratinized gingiva and implant placement time. Moreover, demographic data and oral hygiene methods used in the area of implants were obtained. Results: The prevalence of mucositis in this population was 81.31% of the implants. The average percentage of bleeding score was 29.91%. Of the 107 implants, 52.34% had keratinized tissue. Regarding the use of interproximal tooth cleaning, 43% of patients used dental floss, 26.71% used interdental brush and 20.56% used single brush. It was observed only a weak negative correlation between marginal bleeding and presence of keratinized tissue (p <0.001, r = -0.27). Conclusion: It can be observed a high prevalence of mucositis around the implants, which highlights the need for professionals' greater awareness about oral hygiene guidance and health promotion encouragement in patients receiving dental implant rehabilitation, as well as more studies to investigate the real role of keratinized tissue around implants.

Use Of Social Media

This conceptual paper describes a language learning model that applies social media to foster contextualized and connected language learning in communities. The model emphasizes weaving together different forms of language learning activities that take place in different learning contexts to achieve seamless language learning. It promotes social interactions with social media about the learners’ day-to-day life using the targeted second or foreign language. The paper first identifies three key features of the language learning approach, namely, authenticity, contextualization and socialization. How these features are related to the communicative approach of language learning are subsequently explicated. This is followed by further explication on how the notion of seamless language learning could inform learning designers and learners in synergizing the desired characteristics of language learning together. Eventually, we propose the SMILLA (Social MedIa as Language Learning Artifacts) Framework to operationalize seamless language learning with the use of social media. A case of seamless language learning environment design known as MyCloud will be described to illustrate the practicality of the SMILLA Framework. Este artículo describe un modelo de aprendizaje de lenguas que se sirve de las redes sociales para promover un aprendizaje contextualizado y conectado en comunidades. El modelo propone la interconexión entre diferentes tipos de actividades de aprendizaje en contextos diversos con el objetivo de lograr un aprendizaje discontinuo. Promueve las interacciones sociales a través de los medios compartiendo aspectos de la vida cotidiana en la lengua meta. Este trabajo identifica en primer lugar aspectos clave del enfoque de aprendizaje tales como la autenticidad, la contextualización y la socialización, al tiempo que explica cómo se relacionan estos aspectos con el enfoque comunicativo en el aprendizaje de lenguas. A continuación se presenta una discusión acerca de cómo la noción de aprendizaje discontinuo puede orientar a los creadores de materiales, docentes y aprendientes en la sinergia de todas las características del aprendizaje de lenguas. Para concluir, se propone el modelo SMILLA (Redes sociales como instrumentos para el aprendizaje de lenguas) para poner en práctica la noción de aprendizaje discontinuo con la ayuda de las redes sociales. Los resultados de su aplicación sugieren un potencial efecto sobre los aprendientes, generando usuarios más activos en contextos socialmente significativos, preparados para la autorreflexión sobre el uso que hacen de esa lengua, y con una menor necesidad de intervención del docente.

AbstractIntroductionTobacco use is one of the main causes of periodontitis. E-cigarettes are gaining in popularity, and studies are needed to better understand the impact of e-cigarettes on oral health. Objective: To perform a longitudinal study to evaluate the adverse effects of e-cigarettes on periodontal health.MethodsNaïve e-cigarette users, cigarette smokers, and non-smokers were recruited using newspaper and social media. Demographics, age, gender, and ethnicity, were recorded. Participants were scheduled for two visits 6 months apart. At each visit, we collected data on the daily frequency puffs of an e-cigarette, the number of cigarettes smokes, and other parameters, such as alcohol consumption. Carbon monoxide levels, cotinine levels, salivary flow rate, probing depth, and bleeding on probing were determined at both baseline and follow-up visits. P-values less than 0.05 were considered statistically significant.ResultsWe screened 159 subjects and recruited 140 subjects. One-hundred-one subjects (31 cigarette smokers, 32 e-cigarette smokers, and 38 non-smokers) completed every assessment in both visits. The retention and compliance rate of subjects was 84.1%. The use of social media and craigslist was significant in recruiting e-cigarette subjects. Ethnicity and race differed between cohorts, as did average age in the male subjects. Carbon monoxide and salivary cotinine levels were highest among cigarette smokers. Bleeding on probing and average probing depths similarly increased over time in all three cohorts. Increase in the rates of severe periodontal disease were significantly higher in cigarette smokers and e-cigarette users than non-smokers. Confounding factors were subjects’ age as most of the e-cigarette group were much younger than cigarette smokers.ConclusionAmong the recruited participants, periodontal severity status after 6 month was significantly worse in cigarette smokers and e-cigarette smokers than non-smokers. This study design and protocol will assist in future larger studies on e-cigarette and oral health.
