Assortative and preferential attachment lead to core-periphery networks
Javier Ureña-Carrion, Fariba Karimi, Gerardo Iñiguez +1
Core-periphery is a key feature of large-scale networks underlying a wide range of social, biological, and transportation phenomena. Despite its prevalence in empirical data, it is…
On the inadequacy of nominal assortativity for assessing homophily in networks
Fariba Karimi, Marcos Oliveira
Nominal assortativity (or discrete assortativity) is widely used to characterize group mixing patterns and homophily in networks, enabling researchers to analyze how groups interac…
Improving the visibility of minorities through network growth interventions
Leonie Neuhäuser, Fariba Karimi, Jan Bachmann +2
Improving the position of minorities in networks via interventions is a challenge of high theoretical and societal importance. In this work, we examine how different network growth…
Minorities in networks and algorithms
Fariba Karimi, Marcos Oliveira, Markus Strohmaier
In this chapter, we provide an overview of recent advances in data-driven and theory-informed complex models of social networks and their potential in understanding societal inequa…
Structural inequalities exacerbate infection disparities: A computational approach
Sina Sajjadi, Pourya Toranj Simin, Mehrzad Shadmangohar +4
During the COVID-19 pandemic, we witnessed a disproportionate infection rate among marginalized and low-income groups. Despite empirical evidence suggesting that structural inequal…
First-mover advantage explains gender disparities in physics citations
Hyunsik Kong, Samuel Martin-Gutierrez, Fariba Karimi
Mounting evidence suggests that publications and citations of scholars in the STEM fields (Science, Technology, Engineering and Mathematics) suffer from gender biases. In this pape…
Group mixing drives inequality in face-to-face gatherings
Marcos Oliveira, Fariba Karimi, Maria Zens +3
Uncovering how inequality emerges from human interaction is imperative for just societies. Here we show that the way social groups interact in face-to-face situations can enable th…
A temporal network version of Watts's cascade model
Fariba Karimi, Petter Holme
Threshold models of cascades in the social sciences and economics explain the spread of opinion and innovation due to social influence. In threshold cascade models, fads or innovat…
The Role of Network Structure and Initial Group Norm Distributions in Norm Conflict
Julian Kohne, Natalie Gallagher, Zeynep Melis Kirgil +3
Social norms can facilitate societal coexistence in groups by providing an implicitly shared set of expectations and behavioral guidelines. However, different social groups can hol…
Decay of Relevance in Exponentially Growing Networks
Jun Sun, Steffen Staab, Fariba Karimi
We propose a new preferential attachment-based network growth model in order to explain two properties of growing networks: (1) the power-law growth of node degrees and (2) the dec…
Homophily and minority size explain perception biases in social networks
Eun Lee, Fariba Karimi, Claudia Wagner +3
People's perceptions about the size of minority groups in social networks can be biased, often showing systematic over- or underestimation. These social perception biases are often…
Gender Disparities in Science? Dropout, Productivity, Collaborations and Success of Male and Female Computer Scientists
Mohsen Jadidi, Fariba Karimi, Haiko Lietz +1
Scientific collaborations shape ideas as well as innovations and are both the substrate for, and the outcome of, academic careers. Recent studies show that gender inequality is sti…
Visibility of minorities in social networks
Fariba Karimi, Mathieu Génois, Claudia Wagner +2
Homophily can put minority groups at a disadvantage by restricting their ability to establish links with people from a majority group. This can limit the overall visibility of mino…
Linguistic neighbourhoods: explaining cultural borders on Wikipedia through multilingual co-editing activity
Anna Samoilenko, Fariba karimi, Daniel Edler +2
In this paper, we study the network of global interconnections between language communities, based on shared co-editing interests of Wikipedia editors, and show that although Engli…
Threshold model of cascades in temporal networks
Fariba Karimi, Petter Holme
Threshold models try to explain the consequences of social influence like the spread of fads and opinions. Along with models of epidemics, they constitute a major theoretical frame…
