How data governance technologies can democratize data sharing for community well-being
(Data & Policy, 2021-07-13)Data sharing efforts to allow underserved groups and organizations to overcome the concentration of power in our data landscape. A few special organizations, due to their data monopolies and resources, are able to decide ... -
How data governance technologies can democratize data sharing for community well-being – Corrigendum

How Physical Proximity Shapes Complex Social Networks
(Scientific Reports, 2018-12-07)Social interactions among humans create complex networks and – despite a recent increase of online communication – the interactions mediated through physical proximity remain a fundamental way for people to connect. A ... -
Is social capital associated with synchronization in human communication? An analysis of Italian call records and measures of civic engagement
(EPJ Data Science, 2018-07-17)Social capital has been studied in economics, sociology and political science as one of the key elements that promote the development of modern societies. It can be defined as the source of capital that facilitates cooperation ... -

Large Scale Infrastructure Design Using Evolving Networks
(2020-06-13)This paper discusses the potential use of graph-theoretic framework in the context of large scale infrastructure design and management. Named as the Interdependent Network Flow with Induced Internal Transformation (INFINIT) ... -
Looking for a better future: modeling migrant mobility
(Applied Network Science, 2020-09-22)Massive migrations have become increasingly prevalent over the last decades. A recent example is the Venezuelan migration crisis across South America, which particularly affects neighboring countries like Colombia. Creating ... -
Mapping Time-Varying Accessibility and Territorial Cohesion With Time-Distorted Maps
(IEEE Access, 2019-03-27)Human societies have radically changed from the second half of the 20 th century. Urban areas are increasingly concentrating more people and economic activities. Connections between market economies in different regions ... -
Measuring the predictability of life outcomes with a scientific mass collaboration
(Proceedings of the National Academy of Sciences, 2020-04-14)How predictable are life trajectories? We investigated this question with a scientific mass collaboration using the common task method; 160 teams built predictive models for six life outcomes using data from the Fragile ... -
Mobility patterns are associated with experienced income segregation in large US cities
(Nature Communications, 2021-07-30)Traditional understanding of urban income segregation is largely based on static coarse-grained residential patterns. However, these do not capture the income segregation experience implied by the rich social interactions ... -
Model Based System Design to Support Variability and Flexibility, and Early Bidding Phase of New Procurement
(2020-06-13)A generic design of a complex industrial system allows the reduction in engineering cost and time to market because of the ability to adapt a technical solution given a particular context. We present in this study a ... -
Modelling the impact of testing, contact tracing and household quarantine on second waves of COVID-19
(Nature Human Behaviour, 2020-08-05)While severe social-distancing measures have proven effective in slowing the coronavirus disease 2019 (COVID-19) pandemic, second-wave scenarios are likely to emerge as restrictions are lifted. Here we integrate anonymized, ... -
Network Dynamics of a Financial Ecosystem
(Scientific Reports, 2020-03-12)Global financial crises have led to the understanding that classical econometric models are limited in comprehending financial markets in extreme conditions, partially since they disregarded complex interactions within the ... -
Optimizing targeted vaccination across cyber–physical networks: an empirically based mathematical simulation stud
(Journal of the Royal Society Interface, 2018-01-03)Targeted vaccination, whether to minimize the forward transmission of infectious diseases or their clinical impact, is one of the ‘holy grails’ of modern infectious disease outbreak response, yet it is difficult to achieve ... -

A partial knowledge of friends of friends speeds social search
(PLoS ONE, 2021-08-19)Milgram empirically showed that people knowing only connections to their friends could locate any person in the U.S. in a few steps. Later research showed that social network topology enables a node aware of its full routing ... -
Partnership Ties Shape Friendship Networks: A Dynamic Social Network Study
(Social Forces, 2015-06-26)Partnership ties shape friendship networks through different social forces. First, partnership ties drive clustering in friendship networks: individuals who are in a partnership tend to have common friends and befriend ... -
Prediction and prevention of disproportionally dominant agents in complex networks
(Proceedings of the National Academy of Sciences, 2020-11-03)We develop an early warning system and subsequent optimal intervention policy to avoid the formation of disproportional dominance (“winner takes all,” WTA) in growing complex networks. This is modeled as a system of ... -
Purchase Patterns, Socioeconomic Status, and Political Inclination
(The World Bank Economic Review, 2020-02)This paper analyzes millions of credit card transaction records during several months for tens of thousands of individuals from two different countries. The study shows that, purchase patterns are strongly correlated with ...
