Quantifying social organization and political polarization in online platforms.

Mass selection into groups of like-minded individuals may be fragmenting and polarizing online society, particularly with respect to partisan differences1-4. However, our ability to measure the social makeup of online communities and in turn, to understand the social organization of online platforms, is limited by the pseudonymous, unstructured and large-scale nature of digital discussion. Here we develop a neural-embedding methodology to quantify the positioning of online communities along social dimensions by leveraging large-scale patterns of aggregate behaviour. Applying our methodology to 5.1 billion comments made in 10,000 communities over 14 years on Reddit, we measure how the macroscale community structure is organized with respect to age, gender and US political partisanship. Examining political content, we find that Reddit underwent a significant polarization event around the 2016 US presidential election. Contrary to conventional wisdom, however, individual-level polarization is rare; the system-level shift in 2016 was disproportionately driven by the arrival of new users. Political polarization on Reddit is unrelated to previous activity on the platform and is instead temporally aligned with external events. We also observe a stark ideological asymmetry, with the sharp increase in polarization in 2016 being entirely attributable to changes in right-wing activity. This methodology is broadly applicable to the study of online interaction, and our findings have implications for the design of online platforms, understanding the social contexts of online behaviour, and quantifying the dynamics and mechanisms of online polarization.

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.

Quantifying and contextualizing the impact of bioRxiv preprints through automated social media audience segmentation.

Engagement with scientific manuscripts is frequently facilitated by Twitter and other social media platforms. As such, the demographics of a paper's social media audience provide a wealth of information about how scholarly research is transmitted, consumed, and interpreted by online communities. By paying attention to public perceptions of their publications, scientists can learn whether their research is stimulating positive scholarly and public thought. They can also become aware of potentially negative patterns of interest from groups that misinterpret their work in harmful ways, either willfully or unintentionally, and devise strategies for altering their messaging to mitigate these impacts. In this study, we collected 331,696 Twitter posts referencing 1,800 highly tweeted bioRxiv preprints and leveraged topic modeling to infer the characteristics of various communities engaging with each preprint on Twitter. We agnostically learned the characteristics of these audience sectors from keywords each user's followers provide in their Twitter biographies. We estimate that 96% of the preprints analyzed are dominated by academic audiences on Twitter, suggesting that social media attention does not always correspond to greater public exposure. We further demonstrate how our audience segmentation method can quantify the level of interest from nonspecialist audience sectors such as mental health advocates, dog lovers, video game developers, vegans, bitcoin investors, conspiracy theorists, journalists, religious groups, and political constituencies. Surprisingly, we also found that 10% of the preprints analyzed have sizable (>5%) audience sectors that are associated with right-wing white nationalist communities. Although none of these preprints appear to intentionally espouse any right-wing extremist messages, cases exist in which extremist appropriation comprises more than 50% of the tweets referencing a given preprint. These results present unique opportunities for improving and contextualizing the public discourse surrounding scientific research.

Will Podcasting and Social Media Replace Journals and Traditional Science Communication? No, but...

The digital world in which we live is changing rapidly. The evolving media environment is having a direct impact on traditional forms of communication and knowledge translation in public health and epidemiology. Openly accessible digital media can be used to reach a broader and more diverse audience of trainees, scientists, and the lay public than can traditional forms of scientific communication. The new digital landscape for delivering content is vast, and new platforms are continuously being added. In this article, we focus on several, including Twitter and podcasting, and discuss their relevance to epidemiology and science communication. We highlight 3 key reasons why we think epidemiologists should be engaging with these mediums: 1) science communication, 2) career advancement, and 3) development of a community and public service. Other positive and negative consequences of engaging in these forms of new media are also discussed. The authors of this commentary are all engaged in social media and podcasting for scientific communication, and we reflect on our experiences with these mediums as tools to advance the field of epidemiology.

Positive and negative impact of social media in the COVID-19 era.

Social Media usage has been shown to increase in situations of natural disaster and other crises. It is crucial for the scientific community to understand how social media works in order to enhance our capabilities and make a more resilient community. Through social media communication, the scientific community can collaborate around the globe in a faster way the most important findings of a disease, with a decreased knowledge transition time to other healthcare providers (HCPs). This is greatly important to coordinate research and knowledge during a time of uncertainty and protentional fake news. During the 2020 global pandemic, social media has become an ally but also a potential threat. High volumes of information compressed into a short period can result in overwhelmed HCPs trying to discern fact from noise. A major limitation of social media currently is the ability to quickly disseminate false information which can confuse and distract. Society relies on educated scientists and physicians to be leaders in delivering fact-based information to the public. For this reason, in times of crises it is important to be leaders in the conversation of social media to guide correct and helpful information and knowledge to the masses looking for answers.

Application of a social media platform as a patient reminder in the treatment of Helicobacter pylori.

BACKGROUND: To investigate the effect of a social media platform for the treatment of Helicobacter pylori infection. MATERIALS AND METHODS: We enrolled 222 patients from October 2018 to June 2019, who required H pylori therapy. We used WeChat, a social media platform, as a patient reminder tool. They were randomly divided into the intervention and control groups (n = 111 per group) to compare and evaluate their disease awareness, medication adherence, incidence of adverse drug reactions, and H pylori eradication rate. RESULTS: Patients in the intervention group had significantly better disease-related knowledge, medication adherence, and H pylori eradication rates than those in the control group (P < .05). CONCLUSIONS: Using a social media platform may improve treatment rates of H pylori infection.

More than words: how multimodal analysis can inform health professions education.

The contexts and methods for communicating in healthcare and health professions education (HPE) profoundly affect how we understand information, relate to others, and construct our identities. Multimodal analysis provides a method for exploring how we communicate using multiple modes-e.g., language, gestures, images-in concert with each other and within specific contexts. In this paper, we demonstrate how multimodal analysis helps us investigate the ways our communication practices shape healthcare and HPE. We provide an overview of the theoretical underpinnings, traditions, and methodologies of multimodal analysis. Then, we illustrate how to design and conduct a study using one particular approach to multimodal analysis, multimodal (inter)action analysis, using examples from a study focused on clinical reasoning and patient documentation. Finally, we suggest how multimodal analysis can be used to address a variety of HPE topics and contexts, highlighting the unique contributions multimodal analysis can offer to our field.

Framework for Managing the COVID-19 Infodemic: Methods and Results of an Online, Crowdsourced WHO Technical Consultation.

BACKGROUND: An infodemic is an overabundance of information-some accurate and some not-that occurs during an epidemic. In a similar manner to an epidemic, it spreads between humans via digital and physical information systems. It makes it hard for people to find trustworthy sources and reliable guidance when they need it. OBJECTIVE: A World Health Organization (WHO) technical consultation on responding to the infodemic related to the coronavirus disease (COVID-19) pandemic was held, entirely online, to crowdsource suggested actions for a framework for infodemic management. METHODS: A group of policy makers, public health professionals, researchers, students, and other concerned stakeholders was joined by representatives of the media, social media platforms, various private sector organizations, and civil society to suggest and discuss actions for all parts of society, and multiple related professional and scientific disciplines, methods, and technologies. A total of 594 ideas for actions were crowdsourced online during the discussions and consolidated into suggestions for an infodemic management framework. RESULTS: The analysis team distilled the suggestions into a set of 50 proposed actions for a framework for managing infodemics in health emergencies. The consultation revealed six policy implications to consider. First, interventions and messages must be based on science and evidence, and must reach citizens and enable them to make informed decisions on how to protect themselves and their communities in a health emergency. Second, knowledge should be translated into actionable behavior-change messages, presented in ways that are understood by and accessible to all individuals in all parts of all societies. Third, governments should reach out to key communities to ensure their concerns and information needs are understood, tailoring advice and messages to address the audiences they represent. Fourth, to strengthen the analysis and amplification of information impact, strategic partnerships should be formed across all sectors, including but not limited to the social media and technology sectors, academia, and civil society. Fifth, health authorities should ensure that these actions are informed by reliable information that helps them understand the circulating narratives and changes in the flow of information, questions, and misinformation in communities. Sixth, following experiences to date in responding to the COVID-19 infodemic and the lessons from other disease outbreaks, infodemic management approaches should be further developed to support preparedness and response, and to inform risk mitigation, and be enhanced through data science and sociobehavioral and other research. CONCLUSIONS: The first version of this framework proposes five action areas in which WHO Member States and actors within society can apply, according to their mandate, an infodemic management approach adapted to national contexts and practices. Responses to the COVID-19 pandemic and the related infodemic require swift, regular, systematic, and coordinated action from multiple sectors of society and government. It remains crucial that we promote trusted information and fight misinformation, thereby helping save lives.

How to Fight an Infodemic: The Four Pillars of Infodemic Management.

In this issue of the Journal of Medical Internet Research, the World Health Organization (WHO) is presenting a framework for managing the coronavirus disease (COVID-19) infodemic. Infodemiology is now acknowledged by public health organizations and the WHO as an important emerging scientific field and critical area of practice during a pandemic. From the perspective of being the first "infodemiologist" who originally coined the term almost two decades ago, I am positing four pillars of infodemic management: (1) information monitoring (infoveillance); (2) building eHealth Literacy and science literacy capacity; (3) encouraging knowledge refinement and quality improvement processes such as fact checking and peer-review; and (4) accurate and timely knowledge translation, minimizing distorting factors such as political or commercial influences. In the current COVID-19 pandemic, the United Nations has advocated that facts and science should be promoted and that these constitute the antidote to the current infodemic. This is in stark contrast to the realities of infodemic mismanagement and misguided upstream filtering, where social media platforms such as Twitter have advertising policies that sideline science organizations and science publishers, treating peer-reviewed science as "inappropriate content."

Adapting to the impact of COVID-19: Sharing stories, sharing practice.

Health Professions' Educators (HPEs) and their learners have to adapt their educational provision to rapidly changing and uncertain circumstances linked to the COVID-19 pandemic. This paper reports on an AMEE-hosted webinar: Adapting to the impact of COVID-19: Sharing stories, sharing practice. Attended by over 500 colleagues from five continents, this webinar focused on the impact of the virus across the continuum of education and training. Short formal presentations on teaching and learning, assessment, selection and postgraduate training generated wide-ranging questions via the Chatbox. A thematic analysis of the Chatbox thread indicated the most pressing concerns and challenges educators were experiencing in having to adapt programmes and learning across the continuum of medical education and training. The main areas of concern were: campus-based teaching and learning; clinical teaching; selection and assessment, and educator needs. While there is clearly no one simple solution to the unprecedented issues medical education and training face currently, there were two over-arching messages. First, this is a time for colleagues across the globe to help and support each other. Second, many local responses and innovations could have the potential to change the shape of medical education and training in the future.

Evaluation of the All Right? Campaign's Facebook intervention post-disaster in Canterbury, New Zealand.

The All Right? campaign was developed as a mental health promotion campaign following the 2010-2011 Canterbury earthquakes. One aspect of the overall campaign was the utilisation of social media as a means of promoting wellbeing messages. This research evaluates the use of the All Right? Facebook page as a means of promoting wellbeing after a major natural disaster. Quantitative and qualitative methods were used to gather data about the social media component of the All Right? campaign. Findings indicate that the All Right? Facebook page has become a valued source of consistent wellbeing tips and advice -'the place that I go'. Wellbeing reminders posted on the page were especially valued following earthquake aftershocks. High proportions of respondents to a survey (n = 212) linked from the All Right? Facebook page agreed that the page was helpful (98%), gave people ideas of things that they can do to help themselves (96%), and made people think about their wellbeing (93%). Over four fifths (85%) of respondents had done activities as a result of what they saw on the All Right? Facebook page. Success factors for the Facebook page often mirrored those for the campaign itself, including: local research to inform the use of appropriate language for translating evidence-based wellbeing messages into a local setting; not being marketed as a government message; and effectively combining public health and communications expertise. Success factors specific to the Facebook page included: regular posts with a focus on issues that affect everyone in Canterbury post-disaster; timely posts, especially immediately following aftershocks; a consistent tone for the All Right? Facebook page; and balancing wellbeing facts and tips with other content that was relevant to the Canterbury population. The overall success of the All Right? Facebook page was reliant on being part of a trusted population-wide mental health promotion campaign.

Human papillomavirus (HPV) vaccination: What can be found on the Web? Qualitative analysis of the Doctissimo.fr forum data.

BACKGROUND: Vaccine hesitancy is a major issue in general practice. Regarding human papillomavirus, less than 20% of young French girls are vaccinated. With widespread availability of health information, the Internet seems to be a place of choice to discuss this reluctance. The main objective of this study was to explore perceptions of human papillomavirus vaccination through an analysis of the Doctissimo.fr forum data. METHODS: Using Nvivo software, a qualitative study was carried out from October 2017 to May 2018 on the Doctissimo.fr discussion forum. Online discussion threads not having any message since 2010 were excluded. All threads were analyzed by two independent evaluators. RESULTS: Faced with the doubt that emanated from the discussions and the confusion about the role of the vaccine, Internet users used multiple references in order to develop a reliable discourse. The general practitioner remained a trusted person. While the vaccine was perceived as risky, the cervical smear was approved and encouraged. Although the vaccine remained a feminine concern, males also entered this debate. Through their shared experiences, Internet users tried to influence others about whether or not to get vaccinated. CONCLUSION: Changing the sexual image of the vaccine could help to establish a collective vaccination policy. Public health policies play an essential role by working with general practitioners and by increasing visibility on the web. The usefulness of the vaccine in 2019 seems to be questioned by Internet users as shown by their major approval of cervical smears. However, these two methods remain complementary in the fight against cervical cancer.

The Covid-19 'infodemic': a new front for information professionals.

The virus, commonly known as COVID-19 which emerged in Wuhan, China, in December 2019, has spread in 213 countries, areas or territories around the globe, with nearly 144 683 deaths worldwide on 18 April 2020. In the wake of this pandemic, we have witnessed a massive infodemic with the public being bombarded with vast quantities of information, much of which is not scientifically correct. Fighting fake news is now the new front in the COVID-19 battle. This regular feature comments on the role of health sciences librarians and information professionals in combating the COVID-19 infodemic. To support their work, it draws attention to the myth busters, fact-checkers and credible sources relating to COVID-19. It also documents the guides that libraries have put together to help the general public, students and faculty recognise fake news.

Investigating the beneficial experiences of online peer support for those affected by alopecia: an interpretative phenomenological analysis using online interviews.

BACKGROUND: Those affected by alopecia are at risk of experiencing a range of psychosocial consequences. Alopecia UK provides online peer support via facilitated Facebook pages. Online peer support has been found to provide a variety of benefits in other long-term conditions, such as providing information and emotional support. OBJECTIVES: This study sought to gain an experiential account as to how online support provides benefit to people living with alopecia. METHODS: A purposive sample of 12 participants was recruited directly from Alopecia UK's Facebook group. A total of 11 were diagnosed with alopecia and one participant was a family member of someone with alopecia. The qualitative approach of Interpretative Phenomenological Analysis was used to guide data collection and analysis. Participants took part in online synchronous interviews, which drew on review of participant-selected screenshots of online activity. RESULTS: Four themes were identified, including 'gradual healing', 'image concern', 'belonging' and 'new identity and self-acceptance'. The participants made use of the group through expressing emotion, finding practical advice, and also as a place to connect and share experiences. Participants also reported that the online support facilitated the return of social confidence. CONCLUSIONS: This study provides a detailed understanding as to how online peer support groups can be beneficial. Online groups have the potential to create a feeling of belonging, which can develop a sense of being accepted and understood and as such can be important in maintaining psychological well-being. The findings indicate that online groups have the potential to be used as a platform for assisting people in developing both effective coping styles and feeling understood, and such platforms warrant further investment by healthcare professionals. What's already known about this topic? Alopecia may be associated with psychosocial distress due to both the individual impact and the reactions of others. Online peer support is known to be a beneficial method of providing psychosocial support for people living with a range of health conditions. What does this study add? An in-depth view of the benefits experienced through belonging to an online peer support group for those diagnosed with alopecia, in addressing the psychosocial effects experienced with the condition. This research highlights the need for further investigation of the utility of supporting the development of online peer support for people living with skin conditions. Online peer support groups could be highly effective to use in combination with existing psychological therapies to connect others with shared experience. What are the clinical implications of this work? People living with alopecia can benefit from peer support, and healthcare professionals should ensure that patients know where they can gain access to both psychological support and peer support.

Communication, learning and assessment: Exploring the dimensions of the digital learning environment.

Advances in technology make it possible to supplement in-person teaching activities with digital learning, use electronic records in patient care, and communicate through social media. This relatively new "digital learning environment" has changed how medical trainees learn, participate in patient care, are assessed, and provide feedback. Communication has changed with the use of digital health records, the evolution of interdisciplinary and interprofessional communication, and the emergence of social media. Learning has evolved with the proliferation of online tools such as apps, blogs, podcasts, and wikis, and the formation of virtual communities. Assessment of learners has progressed due to the increasing amounts of data being collected and analyzed. Digital technologies have also enhanced learning in resource-poor environments by making resources and expertise more accessible. While digital technology offers benefits to learners, the teachers, and health care systems, there are concerns regarding the ownership, privacy, safety, and management of patient and learner data. We highlight selected themes in the domains of digital communication, digital learning resources, and digital assessment and close by providing practical recommendations for the integration of digital technology into education, with the aim of maximizing its benefits while reducing risks.

Why and how community pharmacies should better use Facebook.

OBJECTIVE: To describe how independent and community pharmacies can better utilize Facebook to advertise their business and optimize health care communications with patients. DATA SOURCES: Not applicable. SUMMARY: Communication and advertising has changed dramatically over the past decade due to digital technologies. With Facebook leading the way, social media presents an excellent opportunity for independent and community pharmacies to utilize and grow their brand while connecting with patients and help improve public health. Pharmacy as a profession has been slower to uptake the use of social media when compared to other professions. Opportunity exists to utilize Facebook to better connect with patients, colleagues, and advertise pharmacy services. Research has identified several best Facebook practices designed to effectively engage a customer base such as content type/tone, posting frequency, and utilization of paid "boosts," in order to increase reach and better connect with patients and customers from the local community and even globally. CONCLUSION: Potential exists for independent and community pharmacies to utilize Facebook with respect to advertising, connecting with patients, and promoting public health care. When used effectively it has been shown to have a positive return on investment and help improve public health. In a rapidly changing and technological society, pharmacists must continue to adapt and stay informed of digital developments to remain a relevant and viable health care professional.
