Prevalence and Predictors of Posting Health-Related Content Among US Facebook Users
Health-related content is prevalent on Facebook, but we know little about how often the typical user posts about health, the nature of such posts, or the characteristics of users who do so. We conducted a cross-sectional survey of 2508 adult US Facebook users to assess the frequency and predictors of posting about a health condition, health behavior, and health information on Facebook. The findings revealed that 68.7% of participants posted at le…

Assessing the Interplay Between Public Attention and Government Responsiveness With Digital Trace Data
China’s digital campaign to “vaccinate all who can be vaccinated,” officially launched in December 2020, carries global implications. Grounded in the agenda-setting framework to reveal how the responses of different groups are shaped and their agendas interact, this study analyzed two years of Sina Weibo (the largest Chinese microblogging service) and Baidu (the leading search engine in China) search index data to investigate the interrelationshi…
A missing behavioural feedback in Covid-19 models is the key to several puzzles
⇒ Human actions have played a key role in shaping the COVID-19 pandemic patterns. While theoretically recognised, existing models of epidemics often do not endogenously capture many of the feedback loops connecting people’s choices and epidemic dynamics, for example, adoption of non-pharmaceutical interventions (NPIs) by individuals and governments shapes disease transmission, which in turn alters perceived risks and future NPI adoption. ⇒ Such ‘…

Spatial distribution of human capital in Romania
Human capital reflects the knowledge, competencies, and health people invest in and accumulate throughout their lives. Therefore, investing in people's health, education, and skills is essential to developing human capital. The evaluation of human capital is very important for understanding the premises for future development at a territorial level and the impact that different development trajectories may have on economic performance and populat…
Sensitivity analysis for network observations with applications to inferences of social influence effects
The validity of network observations is sometimes of concern in empirical studies, since observed networks are prone to error and may not represent the population of interest. This lack of validity is not just a result of random measurement error, but often due to systematic bias that can lead to the misinterpretation of actors’ preferences of network selections. These issues in network observations could bias the estimation of common network mod…
Affective Ties That Bind
Social networking sites (SNSs) facilitate self-expression and promote social connections. There has been growing scholarly attention to the affect-charged collectivities created online in the aftermath of disasters and mass traumas. This study was designed to examine how individuals affiliate in SNS-based commemoration of a mass trauma, taking advantage of a large Weibo (the Chinese equivalent of Twitter) data set which captures users’ responses …
