ABSTRACT
BACKGROUND: The popularity of the magnetic vaccine conspiracy theory and other conspiracy theories of a similar nature creates challenges to promoting vaccines and disseminating accurate health information. OBJECTIVE: Health conspiracy theories are gaining in popularity. This study's objective was to evaluate the Twitter social media network related to the magnetic vaccine conspiracy theory and apply social capital theory to analyze the unique social structures of influential users. As a strategy for web-based public health surveillance, we conducted a social network analysis to identify the important opinion leaders sharing the conspiracy, the key websites, and the narratives. METHODS: A total of 18,706 tweets were retrieved and analyzed by using social network analysis. Data were retrieved from June 1 to June 13, 2021, using the keyword vaccine magnetic. Tweets were retrieved via a dedicated Twitter application programming interface. More specifically, the Academic Track application programming interface was used, and the data were analyzed by using NodeXL Pro (Social Media Research Foundation) and Gephi. RESULTS: There were a total of 22,762 connections between Twitter users within the data set. This study found that the most influential user within the network consisted of a news account that was reporting on the magnetic vaccine conspiracy. There were also several other users that became influential, such as an epidemiologist, a health economist, and a retired sports athlete who exerted their social capital within the network. CONCLUSIONS: Our study found that influential users were effective broadcasters against the conspiracy, and their reach extended beyond their own networks of Twitter followers. We emphasize the need for trust in influential users with regard to health information, particularly in the context of the widespread social uncertainty resulting from the COVID-19 pandemic, when public sentiment on social media may be unpredictable. This study highlights the potential of influential users to disrupt information flows of conspiracy theories via their unique social capital.

Given the importance of digital communication during the COVID-19 pandemic, the need for advancing academic goals through online social capital is more tangibly felt. This study examined the hypothesis that online social capital can improve the students' academic performance, as one of the main academic goals, through the mediation of knowledge sharing in the online environment. Participants in the study were 376 graduate engineering students from five universities in Iran. The findings indicated that the bridging of online social capital had a positive and significant effect on the cognitive and social integrative benefits of online knowledge sharing. Besides, the social integrative benefits and personal integrative benefits of online knowledge sharing influenced academic performance. Finally, the social integrative benefits and personal integrative benefits had a mediating role in the relationship between the bridging of online social capital and academic performance. Implications of the findings are discussed for the students' academic performance and suggestions are provided for future research.
ABSTRACT
An explosion in Internet use, social networking sites, and COVID-19 has promoted a new concept in health - online social capital, defined as linkages to online social networks that promote trust and group norms. Particularly for the 1.3 million undocumented young adult immigrants who "live in the shadows," the Internet may serve as a place of support and information. This study examines the association between documentation status (defined as Deferred Action for Childhood Arrivals (DACA) status), offline social capital, online social capital, and depressive symptoms among foreign-born Latino and Asian and Pacific Islander young adults in California (N = 208) using data from an internet-based survey conducted in 2017. This study found that those without DACA status had higher online social capital (p < 0.001) and increased depressive symptoms (p = 0.01) than those with DACA status. Using linear regression, we found evidence of online social capital potentially mediating the relationship between DACA status and depressive symptoms. This study also found that as offline social capital increases, the association between online social capital on depressive symptoms decreases. This study points to the power of offline communities and the importance of increasing access to community resources, particularly to those without documentation status who may only have online social networks.
