Background Social media has been widely used for health-related purposes, especially during the COVID-19 pandemic. Previous reviews have summarized social media uses for a specific health purpose such as health interventions, health campaigns, medical education, and disease outbreak surveillance. The most recent comprehensive review of social media uses for health purposes, however, was conducted in 2013. A systematic review that covers various health purposes is needed to reveal the new usages and research gaps that emerge in recent years. Objective This study aimed to provide a systematic review of social media uses for health purposes that have been identified in previous studies. Methods The researchers searched for peer-reviewed journal articles published between 2006 and 2020 in 12 databases covering medicine, public health, and social science. After coding the articles in terms of publication year, journal area, country, method, social media platform, and social media use for health purposes, the researchers provided a review of social media use for health purposes identified in these articles. Results This study summarized 10 social media uses for various health purposes by health institutions, health researchers and practitioners, and the public. Conclusions Social media can be used for various health purposes. Several new usages have emerged since 2013 including advancing health research and practice, social mobilization, and facilitating offline health-related services and events. Research gaps exist regarding advancing strategic use of social media based on audience segmentation, evaluating the impact of social media in health interventions, understanding the impact of health identity development, and addressing privacy concerns.
The evolutionary origin of human right-handedness remains unclear. Many factors such as emotion and tool use have been implicated in primate handedness evolution. With regard to emotional lateralization, most related research focuses on facial asymmetry and behavioral laterality under the non-social context, whereas few studies investigate social laterality. This study, for the first time, investigates the effect of target animacy on hand preference in Old World monkeys, compares our findings with previous related studies in great apes and humans, and aids in filling the knowledge gap on primate handedness evolution. Nine captive northern pig-tailed macaques (Macaca leonina) were chosen as focal subjects in this study. There was no group-level handedness for both animate and inanimate targets. No significant interaction was found between lateral hand use and target animacy. Left-hand use was more frequent than right-hand use for animate targets, whereas right-hand use was more frequent than left-hand use for inanimate targets, both of which demonstrate no significant level. On the whole, northern pig-tailed macaques showed a similar tendency as that in great apes and humans. Regarding handedness linked with emotive stimuli, it is likely that Old World monkeys, great apes and humans evolved from a common ancestor.
Focusing on debunking misinformation about genetically modified (GM) food safety in a social media context, this study examines whether source cues and social endorsement cues interact with individuals’ preexisting beliefs about GM food safety in influencing misinformation correction effectiveness. Using an experimental design, this study finds that providing corrective messages can effectively counteract the influence of misinformation, especially when the message is from an expert source and receives high social endorsements. Participants evaluate misinformation and corrective messages in a biased way that confirms their preexisting beliefs about GM food safety. However, their initial misperceptions can be reduced when receiving corrective messages.
Supplier involvement in new product development (NPD) has received significant attention in the operations management literature. Based on a thorough meta-analysis of correlations for papers published in operations management journals from 1989 to 2014, this study assesses the performance implications of supplier involvement in NPD. The analysis at the aggregate level indicates a significant positive relationship between supplier involvement and overall NPD performance. However, the analysis also indicates that this relationship may be contingent on the presence of various moderating factors. Further, the detailed analysis suggests that it is important to understand that certain supplier involvement dimensions do not simultaneously affect all performance dimensions. This study highlights the dimensions of supplier involvement with the greatest impact, emphasizes the importance of considering moderating factors in future investigations, and identifies areas of future research on the topic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
