Background: Micro-blogging services empower health institutions to quickly disseminate health information to many users. By analysing user data, infodemiology (i.e. improving public health using user contributed health related content) can be measured in terms of information diffusion. Objectives: Tweets by the WHO were examined in order to identify tweet attributes that lead to a high information diffusion rate using Twitter data collected between November 2019 and January 2020. Methods: One thousand hundred and seventy-seven tweets were collected using Python's Tweepy library. Afterwards, k-means clustering and manual coding were used to classify tweets by theme, sentiment, length and count of emojis, pictures, videos and links. Resulting groups with different characteristics were analysed for significant differences using Mann-Whitney U-and Kruskal-Wallis H-tests.
Results:The topic of the tweet, the included links, emojis and (one) picture as well as the tweet length significantly affected the tweets' diffusion, whereas sentiment and videos did not show any significant influence on the diffusion of tweets. Discussion: The findings of this study give insights on why specific health topics might generate less attention and do not showcase sufficient information diffusion.
Conclusion:The subject and appearance of a tweet influence its diffusion, making the design equally essential to the preparation of its content.
Social work has long been involved in child welfare practice. Though lauded as well- intended and admirable work, the profession’s involvement in the child welfare system is fraught with contradictions, ethical tensions, and a legacy of historical trauma and deep mistrust in Black and Native American communities. Challenging this legacy requires an honest look at how schools of social work participate in policies and practices that work to uphold racialized surveillance and forcible family separation. Accordingly, this paper invites readers into a critical conversation regarding social work’s collaboration with child welfare systems via Title IV-E training programs. To these ends, we draw on the conceptual framework of abolition as a useful tool for interrogating and disrupting social work’s relationship to child welfare.
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.
