This week I had the opportunity to present the third paper of my PhD thesis, “Beyond ethnic and migrant categories: From analytical classifications to lived social perceptions of similarity”, co-authored by @mirandalubbers.bsky.social, at the @imiscoe.bsky.social conference in Girona! #IMISCOE

⏳ Only two weeks left to apply! 📣 Call for Proposals | PATCHWORK Final Conference & Data Workshop Deadline: June 15, 2026 Barcelona, Feb 24–26, 2027 Use cross-national network data (N=6,000) + get funding & early access patchwork-erc.eu/en/16/call-f... #SocialNetworks #SNA #Sociology #SocNet

Very pleased to announce Who Follows Whom, a bargain, free to download for the next 2 weeks, looking at patterns of following on Twitter. www.cambridge.org/core/element... The dominant driver of patterns of online attention, with no spatial constraints on who you can connect to, is...

From May 26th to 30th, we had the pleasure of @jimiadams.bsky.social visiting, Professor of Sociology at the @sc.edu. His research addresses how networks constrain or promote the diffusion of information and/or diseases through populations, and he is also active in the area of network methodologies.

📢We invite original research using the cross-national PATCHWORK survey (N=6000) on core & fabulous acquaintances networks & ideational cohesion. Pre-public release access to data+funded presentation at conference in Barcelona, w. Prof. Mario Small 👉 bit.ly/4t4HdnN #OpenData #ERC #NetSci #Sociology

📢Just published! Yunsub Lee (COALESCE Lab) & Xinwei Xu (@socialnetworkslab.bsky.social) show how incorporating more realistic network features dramatically alters Axelrod’s cultural dynamics model, in their new article in Social Networks: www.sciencedirect.com/science/arti... #NetSci #SocialNetworks

Our methodological open-access article (co-authors: Louise Ryan & @alexciordia.bsky.social), presenting new interactive visual tools to inductively explore social categorisation and boundary-making processes within personal networks, is out in Sociological Research Online doi.org/10.1177/1360...

This article might be particularly appealing for people interested in: 🧩 the biographical consequences of activism 🌐 personal network analysis ⚖️ the tension between social cohesion and polarization

Our findings show how political involvement transforms individuals' social environments in complex ways and complicate the view that civil society participation always builds bridges ➡️ In polarized contexts, activism may expand mostly ideologically homogeneous ties but also erode cross-cutting ones.

BUT, interestingly, when asked about the consequences, activists were less troubled (although not unaffected) by these ruptures than non-activists. This is why we call this a "relational toll", a common but acceptable cost of political engagement, likely due to lower aversion to social discomfort.

Why does this happen? We explore this qualitatively. When contrasting activists' and non-activists' accounts of their experiences, three dynamics stood up: 1️⃣ Greater identity exposure 2️⃣ Urge for self-disclosure 3️⃣ Need for ideological alignment

👉 82% of activists (vs 55% for non-activits) reported at least one damaged/broken tie due to political disagreements 👉 After controlling for many dyadic and individual social & political covariates through multi-level regressions, activists were 6-7 times more likely to experience relationship decay

Drawing on 76 personal network interviews and 806 relationships in Catalonia (Spain), a highly polarized context, we found that YES, politicaly-motivated relationship decay is significantly more common among activists 👇

We usually think of political engagement and activism as opportunities for new connections and expanding personal networks. But what about the risks of pre-existing relationships being damaged? Our study asks: are activists more likely to experience politically-motivated relational strain?

🚨🚨📢📢 New open-access article (co-authored w/ @nuriatargarona.bsky.social & @mirandalubbers.bsky.social), just out in American Behavioral Scientist: “The Relational Toll of Political Involvement in Polarized Times: Relationship Decay Within Activists’ Personal Networks” doi.org/10.1177/0002...

New paper in Sociological Methodology with @mbojan.sciences.social.ap.brid.gy, @alexciordia.bsky.social, & @nuriatargarona.bsky.social about the measurement properties of aggregated relational data (responses to "how many people do you know who..?") and NSUM estimates: doi.org/10.1177/0081...
