Social Groups boost the effectiveness of interventions in Social Networks!

In our* new work, we show that contact tracing in networks with groups is more efficient the larger the groups are.

In this new paper, led by Javier Urena-Carrion, we show that fundamental network processes, namely preferential attachment and assortativity, lead to core-periphery structures. /w Mikko Kivelä Gerardo Iñiguez journals.aps.org/prresearch/abs…

New paper alert! With lead author Arttu Malkamäki, Ted Chen, Mikko Kivelä, J. Vesa & T. Ylä-Anttilla we analyze political coalitions in climate politics across three contexts: direct collaboration, legacy media discourse, and social media communication.

#Contact_tracing can be a practical and effective way of containing disease spread. But did you know it's even more effective when social groups are involved?

Have you thought Network Science can be used to analyse transactions in Dark Markets? On 6th April 4pm UK time ,Naomi Arnold from Queen Mary University of London /Northeastern University London will give a talk about 'Temporal graph motifs and how to find them: or how I inadvertently got into big data engineering' (1/4)

Hey NetFollowers, if you are desperately looking for handy tools for temporal networks and hypergraphs, there might be a good option here! Arash Badie-Modiri will talk about “Reticula: A temporal network and hypergraph analysis software package” on 9th Feb at 4pm UK time. (1/4)

Check out our latest paper about our general purpose network library Reticula:
sciencedirect.com/science/articl…

It natively supports (directed || undirected) (dyadic || hypergraph) (static || temporal) networks. C++ with Python bindings.

With Mikko Kivelä, published on SoftwareX Journal

Ladies & gentlemen, Dr. Arash Badie-Modiri 🧑🏻‍🎓

Our (Yan Xia et al.) new paper on the polarization of Finnish NATO discussion!

We find that a leftist anti-NATO bubble merges with a pro-NATO bubble as the Ukraine war starts but a bubble based on disinfo and conspiracy theories stays polarized.

Happy to see this work, led by Sara Heydari Sara Heydari, published! doi.org/10.1016/j.tbs.… We compare different data sources and modeling frameworks for their performances to estimate human mobility between regions in Finland.

It's finally out! Our huge taxonomy and review of randomized reference models for temporal networks is now out in SIAM Review: epubs.siam.org/doi/10.1137/19…

📢JOB ALERT📢

TWO postdoc positions in my group at Computer Science. Come work with me on network science & computational social science topics within new projects related to polarisation in societies, misinformation & coordinated activities on social media.
See mkivela.com/postdoc/

I will be presenting this work at #CCS2022 tomorrow in session 'Networks - Multilayer' from 12:45 (yay last talk of the conference!). Drop by Sala Mozart if you are interested! 😄

Four days into #CCS2022 ! Today, Arash Badie-Modiri Arash Badie-Modiri is going to give a talk about Reticula, a new complex network library he developed. Come to Toponets satellite this morning in Sala Magna if you’re interested! (Also, Arash is on the job market!)

Attending #CCS2022 and interested in spreading phenomenon in networks? Tomorrow, around 16:45 at Sala Magna, I'll be talking about Epidemic Spreading and Contact Tracing On Clique Networks!

Today we (myself and Mikko Kivelä) published a short pre-print on Reticula, our network analysis library for Python and C++ with support for temporal network and/or hypergraphs.

The presence of homophily considerably increases the critical vaccine coverage needed for #herd_immunity and that strong #homophily can push the threshold entirely out of reach. The epidemic size monotonically increases as a function of homophily strength for a perfect vaccine!
