Blockchain-based Framework for Reducing Fake or Vicious News Spread on Social Media/Messaging Platforms

With social media becoming the most frequently used mode of modern-day communications, the propagation of fake or vicious news through such modes of communication has emerged as a serious problem. The scope of the problem of fake or vicious news may range from rumour-mongering, with intent to defame someone, to manufacturing false opinions/trends impacting elections and stock exchanges to much more alarming and mala fide repercussions of inciting violence by bad actors, especially in sensitive law-and-order situations. Therefore, curbing fake or vicious news and identifying the source of such news to ensure strict accountability is the need of the hour. Researchers have been working in the area of using text analysis, labelling, artificial intelligence, and machine learning techniques for detecting fake news, but identifying the source or originator of such news for accountability is still a big challenge for which no concrete approach exists as of today. Also, there is another common problematic trend on social media whereby targeted vicious content goes viral to mobilize or instigate people with malicious intent to destabilize normalcy in society. In the proposed solution, we treat both problems of fake news and vicious news together. We propose a blockchain and keyed watermarking-based framework for social media/messaging platforms that will allow the integrity of the posted content as well as ensure accountability on the owner/user of the post. Intrinsic properties of blockchain-like transparency and immutability are advantageous for curbing fake or vicious news. After identification of fake or vicious news, its spread will be immediately curbed through backtracking as well as forward tracking. Also, observing transactions on the blockchain, the density and rate of forwarding of a particular original message going beyond a threshold can easily be checked, which could be identified as a possible malicious attempt to spread objectionable content. If the content is deemed dangerous or inappropriate, its spread will be curbed immediately. The use of the Raft consensus algorithm and bloXroute servers is proposed to enhance throughput and network scalability, respectively. Thus, the framework offers a proactive as well as reactive, practically feasible, and effective solution for curtailment of fake or vicious news on social media/messaging platforms. The proposed work is a framework for solving fake or vicious news spread problems on social media; the complete design specifications are beyond scope of the current work and will be addressed in the future.

Impact of Media-Based Age Stereotypes on Older Individuals’ Mental Health During the COVID-19 Pandemic

During the COVID-19 pandemic, stigmatization of older persons has increased in traditional and social media. It was unknown whether this negative messaging could be detrimental to the mental health of older individuals, and whether the relatively uncommon positive messaging about older individuals could benefit their mental health. To address these gaps, we designed age-stereotype interventions based on actual news stories that appeared during the pandemic. As expected, the exposure of older individuals to the negative-age-stereotype-messaging interventions led to significantly worse mental health (more anxiety and less peacefulness), compared to a neutral condition; in contrast, the positive-age-stereotype-messaging interventions led to significantly better mental health (less anxiety and more peacefulness), compared to a neutral condition. The results demonstrate the need for media messaging aimed at empowering older individuals during the pandemic and beyond.

Motivating or stigmatising? The public health and media messaging surrounding COVID-19 and obesity: a qualitative think aloud study

PurposeThe purpose of this study is to explore how individuals with overweight and obesity living in the UK respond to the public health and media messaging surrounding COVID-19 and obesity.Design/methodology/approachQualitative interview study with a think aloud protocol. A total of 10 participants self-reported to have overweight, obesity or as actively trying to lose weight were recruited through social media and were asked to think aloud whilst exposed to four sets of public health and media materials describing the link between COVID-19 and obesity. Interviews were conducted over zoom, recorded and transcribed verbatim.FindingsThree primary themes were identified through thematic analysis: “flawed messaging”, “COVID-19 as a teachable moment” and “barriers to change”. Transcending these themes was the notion of balance. Whilst the messaging around COVID-19 and obesity was deemed problematic; for some, it was a teachable moment to facilitate change when their future self and physical health was prioritised. Yet, when focussing on their mental health in the present participants felt more overwhelmed by the barriers and were less likely to take the opportunity to change.Practical implicationsFindings hold implications for public health messaging, highlighting the need for balance between being educational and informative but also supportive, so as to achieve maximum efficacy.Originality/valueThis study offers a novel and useful insight into how the public health and media messaging concerning COVID-19 risk and obesity is perceived by those with overweight and obesity.

Employing Media Messaging Strategies to Respond to COVID-19 Misinformation

Introduction: The COVID-19 pandemic has revealed critical gaps in the public’s knowledge of infectious diseases. Experts, including the World Health Organization, acknowledge that an “infodemic” of misinformation is spreading at the same time as the pandemic. Furthermore, 13% of Canadians age 50 and younger reported using social media as their primary source of information about COVID-19. Thus, in January 2020, the Infectious Disease Working Group (IDWG) was formed by a group of students at the Dalla Lana School of Public Health, University of Toronto. The IDWG’s Media Messaging Team (MMT) uses Knowledge Translation (KT) strategies to increase access to evidence-based information related to public health and COVID-19. Specifically, MMT uses virtual platforms, including Twitter and Instagram (@infectious_info), to disseminate information to a wide audience. Objectives: The MMT aims to produce content to dispel pervasive and harmful myths about COVID-19, raise public awareness, and advocate for health equity. Methods: The team creates 2-4 pieces of original content per week on topics such as Ontario Government legislation updates, myth-busting series, and “Wednesday Series” (summaries of novel research findings). The IDWG employs an equity lens to ensure that the content takes into account the experiences and needs of diverse groups, and that graphics are representative of a diverse audience. Health communication strategies are used to promote audience engagement through compelling and bold content design. Results: The Instagram account has over 4,400 followers, with some posts surpassing 50,000 views. Qualitative feedback from social media followers indicates that this project is addressing an emerging gap in knowledge resulting from unclear messaging from official bodies, the spread of mis/disinformation, and disparities in health literacy levels. Conclusions: The findings can inform the development and implementation of KT strategies to reach a wide audience and increase the uptake of public health information.

‘We went from the anonymity of the internet into my private WhatsApp’: Rituals of transition among dating app users in Berlin

This article focusses on the courtship rituals and practices of intimacy among young dating app users, aged between 20 and 33, in Berlin. Dating app users participate in ‘rituals of transition’ as they signal mutual interest and heightened intimacy by moving conversations from dating apps to social media messaging platforms such as WhatsApp. These rituals of transition play a far more prominent role in signalling romantic interest than the matching-mechanisms inherent in the design of dating apps. Drawing on ethnographic data incorporating 36 semistructured interviews and 45 chat interviews across three popular dating apps, Tinder, Bumble and OkCupid, the study finds that users code the apps installed on their smartphones as hosting spheres of varying intimacy. These spheres are substantiated through the infrastructure of notifications on users’ devices. Rather than drastically altering how users communicate across different apps, rituals of transition are a key moment of communication in themselves.

Living with hepatitis B virus infection; media messaging matters

Hepatitis B Virus (HBV) infection is of public health importance due to its high prevalence and infectivity. A positive test for HBV has psychological, emotional, and socio-economic implications that may affect the quality of life of the clients. The media is a major source of information and awareness creation on many health related issues including HBV. This study explored how media messaging on HBV influenced coping among persons infected with HBV. Twelve in-depth interviews were conducted among clients who reported at the STI clinic for routine care at the Cape Coast Teaching Hospital, Ghana. Descriptive content analysis involving deductive and inductive approaches were applied. The findings show that radio was the main source of HBV related information. Misinformation on the transmission, chronicity and prognoses of HBV infection was mostly conveyed by traditional medicine practitioners on the media. These resulted in adverse emotional, social, and physical reactions such as fear and panic, isolation and loneliness, sleeplessness and unsafe health seeking behaviours. However, access to scientific information from health professionals resulted in empowerment and positive coping. More need to be done to regulate the content of HBV-related messages aired so as to avoid misinformation and its consequent negative impact on coping.
