Effectiveness of Contact Tracing on Networks with Cliques
Abbas K. Rizi, Leah A. Keating, James P. Gleeson +2
Contact tracing, the practice of isolating individuals who have been in contact with infected individuals, is an effective and practical way of containing disease spread. Here, we…
A generating-function approach to modelling complex contagion on clustered networks with multi-type branching processes
Leah A. Keating, James P. Gleeson, David J. P. O'Sullivan
Understanding cascading processes on complex network topologies is paramount for modelling how diseases, information, fake news and other media spread. In this paper, we extend the…
A multi-type branching process method for modelling complex contagion on clustered networks
Leah A. Keating, James P. Gleeson, David J. P. O'Sullivan
Complex contagion adoption dynamics are characterised by a node being more likely to adopt after multiple network neighbours have adopted. We show how to construct multi-type branc…
Calibrating COVID-19 SEIR models with time-varying effective contact rates
James P. Gleeson, Thomas Brendan Murphy, Joseph D. O'Brien +3
We describe the population-based SEIR (susceptible, exposed, infected, removed) model developed by the Irish Epidemiological Modelling Advisory Group (IEMAG), which advises the Iri…
Detect opinion-based groups and reveal polarisation in survey data
Alejandro Dinkelberg, David JP O'Sullivan, Michael Quayle +1
Networks, representing attitudinal survey data, expose the structure of opinion-based groups. We make use of these network projections to identify the groups reliably through commu…
Identification of skill in an online game: The case of Fantasy Premier League
Joseph D. O'Brien, James P. Gleeson, David J. P. O'Sullivan
In all competitions where results are based upon an individual's performance the question of whether the outcome is a consequence of skill or luck arises. We explore this question…
Branching process descriptions of information cascades on Twitter
James P. Gleeson, Tomokatsu Onaga, Peter Fennell +3
A detailed analysis of Twitter-based information cascades is performed, and it is demonstrated that branching process hypotheses are approximately satisfied. Using a branching proc…
Integrating sentiment and social structure to determine preference alignments: The Irish Marriage Referendum
David J. P. O'Sullivan, Guillermo Garduño-Hernández, James P. Gleeson +1
We examine the relationship between social structure and sentiment through the analysis of a large collection of tweets about the Irish Marriage Referendum of 2015. We obtain the s…
