Self-Similarity in Online Networks During Social Movements

Manuel Suarez-Roman, M. Ángeles Serrano, Yérali Gandica

Online platforms provide an infrastructure for social movements, leaving digital traces that can be modelled as networks to quantify how information, participation, and coordinatio…

Temporal patterns of preferences through Wikipedia editing in different languages

David André Villamil Carrillo, Yérali Gandica

Temporal editing patterns on Wikipedia provide a computational lens on cultural dynamics across linguistic communities. We analyse a decade of editorial activity (2001--2010) in el…

Bounded confidence dynamics generates opinion cascades on growing scale-free networks

David Hernandez, Guillaume Deffuant, Yerali Gandica

We study the pairwise bounded confidence model on scale-free networks where new agents regularly arrive over time. The probability that arriving agents form links to preexisting on…

Beyond Trade Openness: Network-Based Evidence on African Economic Integration

Tekilu Tadesse Choramo, Jemal Abafita, Yerali Gandica +1

This paper develops a network-based methodology for measuring economic integration in Africa. Conventional indicators such as trade openness and intra-regional trade shares capture…

An entropic analisis of social demonstrations

Daniel Rico, Yérali Gandica

Social media has dramatically influenced how individuals and groups express their demands, concerns and aspirations during social demonstrations. The study of X or Twitter hashtags…

Fast but multi-partisan: Bursts of communication increase opinion diversity in the temporal Deffuant model

Fatemeh Zarei, Yerali Gandica, Luis Enrique Correa Rocha

Human interactions create social networks forming the backbone of societies. Individuals adjust their opinions by exchanging information through social interactions. Two recurrent…

Bounded confidence model on growing populations

Yérali Gandica, Guillaume Deffuant

This paper studies the bounded confidence model on growing fully-mixed populations. In this model, in addition to the usual opinion clusters, significant secondary clusters of smal…

Signs of criticality in social explosions

Mariano G. Beiró, Ning Ning Chung, Lock Yue Chew +1

The success of an on-line movement could be defined in terms of the shift to large-scale and the later off-line massive street actions of protests. The role of social media in this…

The Detection and effect of social events on Wikipedia data-set for studying human preferences

Julien Assuied, Yérali Gandica

Several studies have used Wikipedia (WP) data-set to analyse worldwide human preferences by languages. However, those studies could suffer from bias related to exceptional social c…

The consequences of hesitation: Axelrod model with intrinsic noise

Rémi Perrier, Yérali Gandica, Laura Hernández

We study the influence of hesitating agents in the Axelrod model by introducing an intrinsic noise, which is proportional to the disagreement between the interacting agents, and th…

Bali's ancient rice terraces: A Hamiltonian approach

Yérali Gandica, J. Stephen Lansing, Ning Ning Chung +2

We propose a Hamiltonian approach to reproduce the relevant elements of the centuries-old Subak irrigation system in Bali, showing a cluster-size power-law distribution. The result…

The free and freer XY models

Petter Holme, Yérali Gandica

We study two versions of the XY model where the spins but also the interaction topology is allowed to change. In the free XY model, the number of links is fixed, but their position…

A multilevel analysis to systemic exposure: insights from local and system-wide information

Yérali Gandica, Sophie Béreau, Jean-Yves Gnabo

In the aftermath of the financial crisis, the growing literature on financial networks has widely documented the predictive power of topological characteristics (e.g. degree centra…

Population preferences through Wikipedia edits

Yérali Gandica

In this work, we are interested in the inner-cultural background shaping broad people's preferences. Our interest is also to track this human footprint, as it has the tendency to d…

Measuring the effect of node aggregation on community detection

Yérali Gandica, Adeline Decuyper, Christophe Cloquet +2

Many times the nodes of a complex network, whether deliberately or not, are aggregated for technical, ethical, legal limitations or privacy reasons. A common example is the geograp…

Fragmentation, integration and macroprudential surveillance of the US financial industry: Insights from network science

Yérali Gandica, Marco Valerio Geraci, Sophie Béreau +1

Drawing on recent contributions inferring financial interconnectedness from market data, our paper provides new insights on the evolution of the US financial industry over a long p…

The role of homophily in the emergence of opinion controversies

F. Gargiulo, Y. Gandica

Understanding the emergence of strong controversial issues in modern societies is a key issue in opinion studies. A commonly diffused idea is the fact that the increasing of homoph…

Stationarity of the inter-event power-law distributions

Yerali Gandica, Joao Carvalho, Fernando Sampaio Dos Aidos +2

A number of human activities exhibit a bursty pattern, namely periods of very high activity that are followed by rest periods. Records of these processes generate time series of ev…

On the origin of burstiness in human behavior: The wikipedia edits case

Yerali Gandica, Joao Carvalho, Fernando Sampaio Dos Aidos +2

A number of human activities exhibit a bursty pattern, namely periods of very high activity that are followed by rest periods. Records of this process generate time series of event…

Can topology reshape segregation patterns?

Yerali Gandica, Floriana Gargiulo, Timoteo Carletti

We consider a metapopulation version of the Schelling model of segregation over several complex networks and lattice. We show that the segregation process is topology independent a…

Nature of phase transitions in Axelrod-like coupled Potts models in two dimensions

Yerali Gandica, Silvia Chiacchiera

We study coupled -state Potts models in a two-dimensional square lattice. The interaction between the different layers is attractive, to favour a simultaneous alignment in a…

Urban skylines from Schelling model

Floriana Gargiulo, Yerali Gandica, Timoteo Carletti

We propose a metapopulation version of the Schelling model where two kinds of agents relocate themselves, with unconstrained destination, if their local fitness is lower than a tol…

A thermodynamic counterpart of the Axelrod model of social influence: The one-dimensional case

Y. Gandica, E. Medina, I. Bonalde

We propose a thermodynamic version of the Axelrod model of social influence. In one-dimensional (1D) lattices, the thermodynamic model becomes a coupled Potts model with a bonding…

Cluster size entropy in the Axelrod model of social influence: small-world networks and mass media

Yérali Gandica, A. Charmell, J. Villegas-Febres +1

We study the Axelrod's cultural adaptation model using the concept of cluster size entropy, that gives information on the variability of the cultural cluster size present i…
