Ethical considerations and methodological uses of Facebook data in public health research: A systematic review.

OBJECTIVE: Since 2016, around seven in 10 adults in the United States (U.S.) actively use Facebook. While much Facebook data is publicly available for research, many users may not understand how their data are being used. We sought to examine to what extent research ethical practices were employed and the research methods being used with Facebook data in public health research. METHODS: We conducted a systematic review (PROSPERO registration CRD42020148170) of social media-based public health research focused on Facebook published in peer-reviewed journals in English between January 1, 2006 and October 31, 2019. We extracted data on ethical practices, methodology, and data analytic approaches. For studies that included verbatim user content, we attempted to locate users/posts within a timed 10-min period. RESULTS: Sixty-one studies met eligibility criteria. Just under half (48%, n = 29) sought IRB approval and six (10%) sought and obtained informed consent from Facebook users. Users' written content appeared in 39 (64%) papers, of which 36 presented verbatim quotes. We were able to locate users/posts within 10 min for half (50%, n = 18) of the 36 studies containing verbatim content. Identifiable posts included content about sensitive health topics. We identified six categories of analytic approaches to using these data: network analysis, utility (i.e., usefulness of Facebook as a tool for surveillance, public health dissemination, or attitudes), associational studies of users' behavior and health outcomes, predictive model development, and two types of content analysis (thematic analysis and sentiment analysis). Associational studies were the most likely to seek IRB review (5/6, 83%), while those of utility (0/4, 0%) and prediction (1/4, 25%) were the least likely to do so. CONCLUSIONS: Stronger guidance on research ethics for using Facebook data, especially the use of personal identifiers, is needed.

Apropriações das mídias na Educação Física: dimensões metodológica, crítica e expressivo-produtiva em questão / Appropriations of media at Physical Education: methodological, critical and expressive-productive dimensions in question / Apropriaciones de medios en Educación Física: dimensiones metodológica, crítica y expresivo-productiva en cuestión

O artigo teve como objetivo compreender as apropriações das mídias pelos professores de Educação Física por meio das dimensões metodológica, crítica e expressivo-produtiva da Mídia-Educação. A etapa empírica envolveu a aplicação de um questionário e a realização de entrevista semiestruturada com professores da Educação Básica da cidade de Goiânia. Constatou-se que as mídias são usadas com um forte caráter instrumental, principalmente no planejamento das aulas. A abordagem crítica e os aspectos éticos e estéticos em relação à criação de conteúdos midiáticos são pouco explorados e sugere a importância de pautar estas questões na formação docente (AU).

This article aim is to understand the appropriations of media by Physical Education teachers by through the methodological, critical and expressive-productive dimensions of media education. It was applied a whole questionnaire conjoined with a semi-structured review to Basic Education teachers of the city of Goiânia. Media are enough used as a strong instrumental role, mainly in class planning. The work highlights that critical approach, as well as ethical and aesthetic aspects concerning media content crafting are not well explored, and ultimately suggests the signification for guiding these issues with respect teaching practice (

Este artículo tiene el objetivo de arrojar luz sobre el incorporación de dichos medios en relación con los docentes de Educación Física a través de un ámbito metodológico-crítico y expresivo-productivo da educación mediática. Se aplicó un cuestionario completo junto con una revisión semiestructurada a los docentes de Educación Básica en la ciudad de Goiânia. Los medios se utilizan suficientemente como un papel instrumental fuerte, principalmente en la planificación de clases. El enfoque crítico, así como los aspectos éticos y estéticos relacionados con la elaboración de contenidos mediáticos, no están bien explorados y, sugiere el significado de orientar estos temas con respeto a la práctica docente (AU).

Learning through the grapevine and the impact of the breadth and depth of social networks.

We study how communication platforms can improve social learning without censoring or fact-checking messages, when they have members who deliberately and/or inadvertently distort information. Message fidelity depends on social network depth (how many times information can be relayed) and breadth (the number of others with whom a typical user shares information). We characterize how the expected number of true minus false messages depends on breadth and depth of the network and the noise structure. Message fidelity can be improved by capping depth or, if that is not possible, limiting breadth, e.g., by capping the number of people to whom someone can forward a given message. Although caps reduce total communication, they increase the fraction of received messages that have traveled shorter distances and have had less opportunity to be altered, thereby increasing the signal-to-noise ratio.

O cumprimento da Lei nº 13168 de 6 de outubro de 2015 por cursos de Odontologia do Sul e Sudeste do Brasil: uma análise dos sítios eletrônicos institucionais / Compliance with Law nº 13168 of October 6, 2015, by Dentistry courses in the South and Southeast of Brazil: an analysis of institutional websites

A Lei nº 13.168, de 6 de outubro de 2015, determina entre outros aspectos, que as Instituições de Ensino Superior (IES) brasileiras tragam em seus sítios eletrônicosoficiaisinformações relativas àmatrizcurricular e corpo docente do curso ofertado. O objetivo deste estudo foi avaliar a prevalência de cumprimento dessa lei em IES que ofertam o curso de Odontologia, tendo como amostra IES das regiões Sudeste e Sul do país. Para isso, as IES foram catalogadasa partir doportal e-MEC do Ministério da Educação, e posteriormentetiveram seus sítios eletrônicos oficiais acessados. Observou-seentão o cumprimento das determinações do artigo, parágrafo, incisos, e alíneas da referida lei. Os dados foram descritos por meio defrequências absolutas e relativas e comparados pelo Teste Exato de Fisher (α=5%). Aplicados os critérios de elegibilidade, 256 IES foram incluídas, sendo 220 IES privadas e 36 públicas. De acordo com os critérios de análise adotados, apenas 3 (1,17%) das IES cumpriram todas as exigências da lei. A disponibilização da lista das disciplinas que compõem a matriz curricular de cada curso foi de 78,1%. Por outro lado, informações relativas ao corpo docente foram disponibilizadas por uma baixa porcentagem de IES, tais como identificação do corpo docente (40,6%), as disciplinas que efetivamente cada docente leciona (13,7%), titulação (30,1%) e tempo de trabalho na IES (8,6%). Do mesmo modo, uma baixa porcentagem foi observada quanto àatualização (11,7%) e data completa da última atualização (14,8%). Em conclusão, a maior parte das IES analisadas não está de acordo com Lei nº 13.168/15, sendo necessário que os coordenadores de curso e gestores estejam atentosà necessidade de adequação dos sítios eletrônicos institucionais (AU).

Law No. 13,168, of October 6, 2015, determines, among other things, that Brazilian Higher Education Institutions (HEIs) bring on their official websites information regarding the curriculum and teaching staff of the course offered. The aim of this study was to assess the prevalence of compliance with this law in HEIs that offer the Dentistry course, using HEIs from the Southeast and South regions of the country as a sample. For this, the HEIs were cataloged on the Ministry of Education's e-MEC portal, and later had their official websites accessed. It was observed whether the HEI portals complied with the provisions of the article, paragraph, items, and paragraphs of the aforementioned law. Data were described using absolute and relative frequencies and compared using Fisher's exact test at a significance level of 5%. After applying the eligibility criteria, 256 HEIs were included, being 220 private HEIs and 36 public. According to the analysis criteria adopted, only 3 (1.17%) of the HEIs complied with all the requirements of the law. The availability of the list of subjects that make up the curriculum of each course was 78.1%. On the other hand, information related to the teaching staff was made available by a low percentage of HEIs, such as identification ofthe teaching staff (40.6%), the subjects that each professor actually teaches (13.7%), titles (30.1 %), and working time at the HEI (8.6%). Likewise, a low percentage was observed regarding the updating of the curriculum (11.7%) and the presence of the complete date of the last update (14.8%). In conclusion, most Brazilian Dentistry HEIs do not comply with Law No. 13.168/15, making it necessary for course coordinators and education managers to pay attention to the need to adapt institutional websites (AU).

Improving fake news classification using dependency grammar.

Fake news is a complex problem that leads to different approaches used to identify them. In our paper, we focus on identifying fake news using its content. The used dataset containing fake and real news was pre-processed using syntactic analysis. Dependency grammar methods were used for the sentences of the dataset and based on them the importance of each word within the sentence was determined. This information about the importance of words in sentences was utilized to create the input vectors for classifications. The paper aims to find out whether it is possible to use the dependency grammar to improve the classification of fake news. We compared these methods with the TfIdf method. The results show that it is possible to use the dependency grammar information with acceptable accuracy for the classification of fake news. An important finding is that the dependency grammar can improve existing techniques. We have improved the traditional TfIdf technique in our experiment.

Social Media Guidelines for Young Plastic Surgeons and Plastic Surgery Training Programs.

SUMMARY: Social media are a powerful tool that creates a unique opportunity for the young plastic surgeon and trainee to share content, brand oneself, educate the public, and develop one's own professional voice early. The majority of all plastic surgery programs and particularly those that are highly ranked have social media opportunities for their residents, yet clear rules to guide implementation of social media programming in residency have remained unspecified. These guidelines and pitfalls can be used to inform a productive and professional entry into plastic surgery social media use for the resident and young plastic surgeon. Details regarding specific platform use to maximize exposure are provided. The core principles of patient safety and privacy, authentic photography, plastic surgery education and advocacy, and professionalism inform these guidelines. Pitfalls include establishment of an online physician-patient relationship, engaging in debate by means of online reviews, providing medical entertainment, and engaging in non-plastic surgery politics. Use of these guidelines will allow the young plastic surgeon and trainee to succeed by means of social media platforms in an ethical and professional manner.

Ageism in COVID-Related Newspaper Coverage: The First Month of a Pandemic.

OBJECTIVES: Media sources have consistently described older adults as a medically vulnerable population during the coronavirus disease 2019 (COVID-19) pandemic, yet a lack of concern over their health and safety has resulted in dismissal and devaluation. This unprecedented situation highlights ongoing societal ageism and its manifestations in public discourse. This analysis asks how national news sources performed explicit and implicit ageism during the first month of the pandemic. METHOD: Using content and critical discourse analysis methods, we analyzed 287 articles concerning older adults and COVID-19 published between March 11 and April 10, 2020, in 4 major U.S.-based newspapers. RESULTS: Findings indicate that while ageism was rarely discussed explicitly, ageist bias was evident in implicit reporting patterns (e.g., frequent use of the term "elderly," portrayals of older adults as "vulnerable"). Infection and death rates and institutionalized care were among the most commonly reported topics, providing a limited portrait of aging during the pandemic. The older "survivor" narrative offers a positive alternative by suggesting exceptional examples of resilience and grit. However, the survivor narrative may also implicitly place blame on those unable to survive or thrive in later life. DISCUSSION: This study provides insight for policy makers, researchers, and practitioners exploring societal perceptions of older adults and how these perceptions are disseminated and maintained by the media.

Anti-intellectualism and the mass public's response to the COVID-19 pandemic.

Anti-intellectualism (the generalized distrust of experts and intellectuals) is an important concept in explaining the public's engagement with advice from scientists and experts. We ask whether it has shaped the mass public's response to coronavirus disease 2019 (COVID-19). We provide evidence of a consistent connection between anti-intellectualism and COVID-19 risk perceptions, social distancing, mask usage, misperceptions and information acquisition using a representative survey of 27,615 Canadians conducted from March to July 2020. We exploit a panel component of our design (N = 4,910) to strongly link anti-intellectualism and within-respondent change in mask usage. Finally, we provide experimental evidence of anti-intellectualism's importance in information search behaviour with two conjoint studies (N ~ 2,500) that show that preferences for COVID-19 news and COVID-19 information from experts dissipate among respondents with higher levels of anti-intellectual sentiment. Anti-intellectualism poses a fundamental challenge in maintaining and increasing public compliance with expert-guided COVID-19 health directives.

Guidance on the use of social media in reproductive medicine practice.

The term "social media" refers to computer-mediated technologies that enable individuals and communities to gather, communicate, network, and share information. These technologies represent useful tools for enabling individual providers and their clinics to broadcast content that educates, informs, advertises, and narrates content to a larger audience. There are multiple benefits to maintaining a presence on social media, either as an individual physician or as a clinic, but several pitfalls deserve consideration as well. This guidance document does not endorse any specific cloud-based platform or service, though some are mentioned for the purposes of illustration.
