Integrity Risk Indicators by SCImago introduce a common standard to measure institutional integrity risk. Not about prestige, but about identifying risk patterns and enabling fair, evidence-based oversight. Toward more transparent research governance bit.ly/4dqVuH5 #IRIS

Дослідницька група @scimago представила ще один новий інструмент – SCImago Journal Value. Ідея проста і водночас провокативна: якщо журнали мають науковий вплив, то чи можна оцінити їхню приблизну “економічну вартість”? panbibliotekar.blogspot.com/2026/03/blog-p…

Stanford researchers checked 6 major AI companies and found they all use your chats to train models. Users unknowingly hand over highly sensitive medical or personal details that become permanent parts of future AI brains. The problem with standard privacy rules is that they scatter important details across multiple files so people cannot find them. The researchers at Stanford HAI examined 28 privacy documents across these six companies not just the main privacy policy, but every linked subpolicy, FAQ, and guidance page accessible from the chat interfaces. They evaluated all of them against the California Consumer Privacy Act, the most comprehensive privacy law in the United States. The results are worse than you think. Every single company collects your chat data and feeds it back into model training by default. Some retain your conversations indefinitely. There is no expiration. No auto-delete. Your data just sits there, forever, feeding future versions of the model. Some of these companies let human employees read your chat transcripts as part of the training process. Not anonymized summaries. Your actual conversations. But here's where it gets genuinely dangerous. In many cases these chats, get merged with everything else those companies already know about you. Your search history. Your purchase data. Your social media activity. Your uploaded files. The researchers describe a realistic scenario that should make you pause: You ask an AI chatbot for heart-healthy dinner recipes. The model infers you may have a cardiovascular condition. That classification flows through the company's broader ecosystem. You start seeing ads for medications. The information reaches insurance databases. The effects compound over time. You shared a dinner question. The system built a health profile. ---- Paper Link – arxiv. org/abs/2509.05382 Paper Title: "User Privacy and LLMs: An Analysis of Frontier Developers' Privacy Policies"

@Rednaki Muy chulo!

Queremos dar a conocer SILICE, @silicebuscador, una plataforma abierta y flexible para el análisis de la producción científica en España. Creada en 2024, hoy nos la presenta en Dciencia @JLOrtegaPriego de @iesa_csic , uno de sus creadores. dciencia.es/caminando-haci…

The first infographics are now available on the SCImago Integrity Risk Indicators platform (scimagoiris.com/viztools.php). These charts allow users to filter IRIS results by region and indicator for the period 2020-2024, based on Scopus data.

¡Excelente iniciativa! Los riesgos en integridad científica se deben trabajar de manera integral, con objetivos claros y resultados tangibles. #SCImagoIRIS contribuye al análisis y toma de decisiones: scimagoiris.com/integrity-risk…

9/9 Authors have long advocated for professionalizing university journals with adequate funding & infrastructure. There's huge value in Spanish journals, so go fund our journals! (That's the professor in me speaking) 🎓

8/9 Academic societies show remarkable publishing efficiency, achieving high value relative to size with varied portfolios. Meanwhile, public publishers are essential infrastructure for disciplines neglected by commercial ones. See Social Sciences & Humanities (pink) 📚

1/9 Just out! Our paper "Scholarly Publishing in Spain: An Analysis Based on the Estimated Financial Value of Journals". doi.org/10.1007/s12109… Coauthors: @felixdemoya, @GaliHalevi, @bo28482 You can read the paper using the SharedIt service at rdcu.be/e7RhZ
