Presenting our ontology proposal for geospatial exposome data at the Int'l Society of Exposure Science workshop in Lisbon. Nice to see that it already attracts great interest from other groups, highlighting the need for metadata standards in the exposome field. Feedback is welcome. osf.io/sy256

Today was my last day at Queen's. Grateful to have worked with an inspiring PI, Ruth Hunter, and brilliant teams on several exciting projects. Last 3 years have been truly a period of growth! Lately, I was asked to draw what my last project means to me 👇 The project: www.qub.ac.uk/sites/ground...

🔦 How can such AI be used? Our model enables surveillance of tobacco-promoting content both for research purposes and enforcement of tobacco control measures. Beyond that, we suggest a range of health promotion opportunities this tool can help.

🏷️ Qualitative 2 - We manually coded a small sample of social media posts. Some posts fell easily into one category (Fig1), yet others were more complicated and required us to use a matrix (Fig2).

We used mixed-methods 💬 Qualitative 1 - We inductively identified four main ways of tobacco promotion in social media: modelling the behaviour, expressing positive attitudes, recommending use, and marketing brands or vendors.
