Desinformación en tiempos de pandemia: tipología de los bulos sobre la Covid-19
No full textSe presenta un análisis de contenido de todos los bulos (N=292) relacionados con la pandemia Covid-19 identificados por las tres plataformas de verificación acreditadas en España, durante el primer mes del estado de alarma decretado por el Gobierno (14 marzo 2020 – 13 abril 2020). El estudio muestra que los bulos sobre el coronavirus fueron diseminados principalmente en las redes sociales y, entre ellas, sobre todo en las cerradas, como la aplicación móvil de mensajería WhatsApp. También detecta las particularidades formales y de contenido más frecuentes de los contenidos falsificados. Los resultados revelan que la pandemia, además de generar un gran número de bulos sobre salud y ciencia, casi un tercio de la muestra, también propició la difusión de numerosos contenidos falsos de tema político y gubernamental. El artículo explora los formatos, fuentes y territorios de procedencia de los bulos. Más allá de sus resultados empíricos, este estudio realiza contribuciones teóricas en el marco de los emergentes estudios sobre desórdenes informativos. En concreto, aporta una definición propia de bulo, así como una tipología en la que se identifican cuatro tipos de bulos: broma, exageración, descontextualización y engaño. A partir de esos cuatro tipos, se propone un ‘diagrama de gravedad de los bulos’
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Desinformación de género: análisis de los bulos de Maldito Feminismo
No full textInformation disorder (satire or parody, false connections, misleading content, false context, imposter content, manipulated content or fabricated content) must be considered a social problem that is causing collective damages and threating digital society. Women, in particular, are becoming victims of hostilities on the virtual interaction spaces. This problem is currently known as “digital sexism” and “gender disinformation”. In this space, verification journalism, a trendy format, aims to reduce the effects of hoaxes introducing the fact-checking process in its professional routines. However, this is still a minority task. In order to contribute to the study of the disinformation phenomenon in relation to online messages about women, this research has developed a systematic tool to classify hoaxes that have been refuted by the platform Maldita.es, specifically, fake news that has been published on it sections Maldito Feminismo (N=71).
The results of this study (internal validity) show that hoaxes detected by Maldito Feminismo are misleading content that expect to damage feminism (this is the main topic of fake news) and have a political purpose. These information disorders are displayed in text format and are mainly created and distributed on social networks. Moreover, although users collaborate and participate detecting and reporting hoaxes, the platform Maldito Feminismo identifies, locates and denounces most of the fake news.El desorden informativo (sátira o parodia, conexión falsa, contenido engañoso, contexto falso, contenido impostor, contenido manipulado o contenido fabricado) debe ser considerado como un problema social en la medida en que se empiezan a demostrar sus daños colectivos, que amenazan a la sociedad digital. De forma particular, las mujeres están siendo víctimas de hostilidades en los espacios de interacción virtuales, lo que se empieza a conocer como “sexismo digital” y “desinformación de género”.
En este escenario, el periodismo de verificación, un formato tendencia, trata de paliar los efectos de los bulos introduciendo, entre sus rutinas profesionales, el desmentido de esos contenidos; sin embargo, aún es un trabajo minoritario. Para contribuir al estudio del fenómeno de la desinformación, en relación con los mensajes que circulan en Internet sobre las mujeres, esta investigación propone una herramienta de clasificación sistemática de los bulos desmentidos por el medio Maldita.es, en concreto, aquellos publicados en su sección Maldito Feminismo (N=71).
Los resultados de este estudio (que tienen una validez interna) revelan que los bulos detectados por Maldito Feminismo son noticias falsas de contenido engañoso, que buscan dañar el feminismo (ya que este es el tema principal de la mayoría de bulos analizados) y tienen un propósito político. Estos desórdenes informativos se crean y distribuyen, principalmente, a través de las redes sociales en formato texto. Aunque los usuarios colaboran y participan en la detección y denuncia de los bulos, normalmente, suele ser la plataforma Maldita Feminismo quien identifica, localiza y delata la mayoría de noticias falsas.A desordem informativa (sátira ou paródia, conexão falsa, conteúdo enganoso, contexto falso, conteúdo impostor, conteúdo manipulado ou conteúdo fabricado) deve ser considerada um problema social enquanto os danos coletivos que provoca e que ameaçam à sociedade digital começam a ser descobertos. Particularmente, as mulheres são vítimas de hostilidades nos espaços de interação virtuais. Esse fenômeno é conhecido como “sexismo digital” e “desinformação de gênero”.
Neste cenário, o jornalismo de verificação (oufact checking journalism em inglês), um formato que é tendência, tenta paliar os efeitos das calúnias ou difamações a introduzir nas rotinas profissionais a prática de desmascarar essas calúnias. Contudo ainda é um trabalho pouco expandido. Para contribuir ao estudo do fenômeno da desinformação em relação com as mensagens que circulam na Internet sobre as mulheres, esta investigação propõe uma ferramenta de classificação sistemática das calúnias desmascaradas pela Maldita.es na seção Maldito Feminismo (N=71).
Os resultados deste estudo revelam que as calúnias detectadas pela seção Maldito Feminismo são notícias falsas de conteúdo enganoso. Esses conteúdos têm a intenção de prejudicar ao feminismo (este é o assunto principal da maior parte das calúnias analisadas) com um propósito político. Essas desordens informativas são criadas e distribuídas principalmente pelas redes sociais na forma de texto. Embora os usuários colaboram e participam na detecção e denúncia dessas calúnias, é a plataforma Maldito Feminismo à que frequentemente identifica, localiza e desmascara a maior parte das notícias falsas.
 
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
