In this post, I revisit my thesis on human-centered computing, human computation, reflecting on engagement, credibility, and the developments ten years after the oral defence. What interesting activities occurred after the PhD thesis oral examination? What was the main challenge and the main satisfaction of the PhD research? What is the future of research in the areas investigated during the PhD? Many accounts and stories presented here are not present in the thesis. https://lesandrop.github.io/site/papers/how-citizens-engage-with-the-social-media-presence-of-climate-authorities.html https://lesandrop.github.io/site/papers/how-citizens-engage-with-the-social-media-presence-of-climate-authorities.html Mon, 12 May 2025 10:00:00 GMT Lesandro Ponciano Research Article This study published in npj Climate Action (Nature Portfolio) explores how citizens interact with climate authorities on social media in five Brazilian cities during extreme weather events. Key findings reveal that authorities rely on passive posting, citizen engagement is short-term and reactive, replies focus on corrections rather than climate change links, and limited two-way communication occurs.
