New & OA w/ @lutzid.bsky.social in @icsjournal.bsky.social: The role of personality in bystander reactions to online pol. hostility. We find that both active (counterspeech) & passive (silencing) reactions negatively relate to agreeableness & conscientiousness 1/3 www.tandfonline.com/doi/full/10....

Propensity for impression management, mostly in assertive or confrontative manner (often independent of political interest), predicts political engagement on Facebook, German research by @cphoffmann.bsky.social & @lutzid.bsky.social suggests:

This is nuts. Too much money is going to specific grants about AI and STEM, and all the others need to fight for scraps.

We need more funding for social sciences and the arts immediately.

X’s Altmetric Hegemony Ceding to Bluesky The alternative social media platform is matching engagement of Elon Musk’s X in ways that “would have seemed unthinkable until recently,” says study.

3 💡 conclusions from this @timeshighered.bsky.social piece based on @altmetric.com data:

1️⃣ Academic twitter is dead
2️⃣ Bluesky is the most promising alternative
3️⃣ There is a lot of underused 🦋 potential with many dormant (institutional) accounts

2️⃣ In "Mapping the prestige and social value of occupations in the digital economy", published in JBR, we focus on emerging occupations, showing how these jobs suffer from perceptional deficits and are subject to varied assessments along demographic lines.

1️⃣ In "Occupational prestige and occupational social value in the United Kingdom", published in RSSM, we document the development of a comprehensive occupation list aligned with ISCO-08, discussing the prestige and social value landscape in the UK.
🔗 doi.org/10.1016/j.rs...

👇 Here is a layperson summary of the research: www.bi.edu/research/bus...

🧱 The article builds on two earlier papers from the occupational prestige and occupational social value project that both came out last year.

💡 We investigated how generative AI evaluates 576 occupations, contrasting GPT-4 prestige and social value scores with human scores in the UK. The two are highly correlated across all ISCO-08 major groups. However, GPT-4 misrepresents many occupations, especially digital economy and illicit ones.

📖 Our article "A technological construction of society: Comparing GPT-4 and human respondents for occupational evaluation in the UK" with P. Gmyrek and @gemmanewlands.bsky.social has been included in the March 2025 issue of the British Journal of Industrial Relations!
