NetSci2020 Political Communication Networks

event picture

Online 18/09/2020

The aim of the PCNet20 satellite is to provide a forum where qualitative and quantitative methods in political communication studies can interact and mutually cross-fertilize.

Traditionally, news media served as an interface between citizens and politics, eventually influencing the political behaviour together with the context and social networks embeddedness.

In the information age, both politics and communication are transformed. The popularity of online social platforms  has increased the number of actors able to spread political, commercial and other messages to a massive number of potential recipients. In this workshop, we want to explore and characterize such phenomena through the lens of network science. 



  • Networked Collective Political Identities

  • Context collapse

  • Online Culture Wars

  • Diffusion of News and Misinformation

  • Selective Exposure, Echo Chambers and Polarization

  • Emergence of leaderships

  • Digital Parties Platform Communication

  • Data based propaganda

  • Populism (operative definition / quantification)

  • The Rise of the far right


The extended deadline for abstract submission is July 15th, 2020.
Notifications of acceptance will be sent via e-mail by July 20th, 2020.

Webinar 16/07/2020

Date: 16 July, 16h (CET, GMT+2, Barcelona/Madrid/Paris/Berlin)

Speaker: Ernesto Estrada, IUMA, Universidad de Zaragoza

Title:  “Fractional diffusion on the human proteome as an alternative explanation to the multi-organ damage of SARS CoV-2"

Link to the webinar:


SARS CoV-2 is the new coronavirus causing the pandemic known as COVID-19. This respiratory disease is characterized by multi-organ and systemic damages in patients. The abundance of ACE2 on human organs has been claimed as responsible for such multi-organ spread of the virus damages. However, once on circulation the virus could spread to practically every organ in the human body as
ACE2 is ubiquitous on endothelia and smooth muscle cells of virtually all organs. Contrastingly, SARS CoV-2 only damages selectively a few organs. Here, we develop the hypothesis that the effects of the SARS CoV-2 virus can be spread through the human protein-protein interaction (PPI) network in a subdiffusive way. We then elaborate a time-fractional diffusion model on networks which allow
us to study this phenomenon. Starting the diffusion from the SARS CoV-2 Spike protein to the human PPI network we show here that the pertubations can spread across the whole network in very few steps. Consequently, we discover a few potential routes of propagation of these perturbations from proteins mainly expressed in the lungs to proteins mainly expressed in other different tissues, such as
the heart, cerebral cortex, thymus, lymph node, testis, prostate, liver, small intestine, duodenum, kidney, among others already reported as damaged by COVID-19.

Barcelona Webinar 02/07/2020

Date: 2 July, 16h (CET, GMT+2, Barcelona/Madrid/Paris/Berlin)

Speaker: Alex Arenas, DEIM, Universitat Rovira i Virgili​

Title:  “Epidemics and mobility”

Link to the webinar:


Reaction–diffusion processes have been widely used to study epidemics in networked metapopulations. In the context of epidemics, reaction processes are understood as contagions within each subpopulation (patch), while diffusion represents the mobility of individuals between patches. Recently, the characteristics of human mobility, such as its recurrent nature, have been proven crucial to understand the phase transition to endemic epidemic states. Here, we present a framework able to cope with the elementary epidemic processes, the spatial distribution of populations and the commuting mobility patterns. We will show after, how this framework has been adapted to describe the COVID-19 pandemic.

Webinar 25/06/2020

Date: 25 June, 16h (CET, GMT+2, Barcelona/Madrid/Paris/Berlin)

Speaker: Santiago F. Elena, Institute for Integrative Systems Biology, CSIC​

Title: "Why some patients develop a severe syndrome while other remain asymptomatic? Early-warning signals associated with the phase transition from health to disease."

You can see the webinar here:


Abstract: One of the most outstanding observations during COVID-19 pandemics is that some patients have an asymptomatic infection while others suffer severe symptoms, some of them becoming fatal. Is there any relation between the global gene expression state of patients and they propensity to suffer an asymptomatic infection? Is it possible to identify which genes, or groups of them within a regulation network, may serve as markers to predict the clinical fate of a patient before the presence of any symptom? In this seminar I will introduce the fundamentals of the theory of Dynamical Biomarkers of Networks (DBN), illustrating their application to the analysis of transcriptomic data during disease progression in a pathosystem model.


Títol: "Perquè alguns pacients desenvolupen símptomes severs mentre uns altres són asimptomàtics? Biomarcadors d'una transició de fase associada a la progressió de la malaltia”

Resum: Una de les observacions més destacables fetes durant l'epidèmia de la COVID-19 és que alguns pacients passen la infecció de manera asimptomàtica mentre que uns altres pateixen símptomes severs que en un percentatge de casos tenen un desenllaç fatal.  Existeix alguna associació entre l'estat d'expressió gènica global dels pacients i la seua propensió a patir una infecció asimptomàtica?  És possible identificar quins gens, o grups d'ells en una xarxa de regulació, servirien de marcadors per a predir el destí clínic d'un pacient abans que mostre cap símptoma?  En aquesta xarrada presentaré els fonaments de la  teoria dels biomarcadors dinàmics de xarxes (DNB) i il·lustraré la seua aplicació a l'anàlisi de dades transcriptòmics presos al llarg de la progressió de la malaltia en un patosistema model.

Barcelona Webinar 11/06/2020

Speaker: Manlio de Domenico, CoMuNe Lab, Fondazione Bruno Kessler

Title: "Tackling complexity: foundations and applications"


Complex systems consists of units whose interactions at a microscopic scale lead to the spontaneous emergence of collective behavior and other unexpected phenomena at the meso- and macroscale. In this seminar I will introduce some basic concepts and tools of complexity science without relying on technicalities.
In the second part of the seminar I will briefly discuss the relevance of big data for the analysis of complex systems and, more specifically, of socio-technical systems, spanning from the rise of collective attention to one of the most relevant phenomena observed during the COVID-19 pandemic: the infodemic related to coronavirus.

About complexity science and social systems

How can complexity science help us better understand past and present complex social systems as diverse as online social networks or the Roman economy? This half-day workshop will explore the role complexity science, and in particular its use of network approaches, can play for the study of the human present and past.

Complexity science is now a thriving field and its application for the study of the human past shows huge potential. This workshop will explore this potential.
