The emergent integrated network structure of scientific research
Scientific research is often thought of as being conducted by individuals and small teams striving for disciplinary advances. Yet as a whole, this endeavor more closely... -
Optimal Legislative County Clustering in North Carolina
North Carolina's constitution requires that state legislative districts should not split counties. However, counties must be split to comply with the "one person, one vote"... -
Characterizing and modeling citation dynamics
Citation distributions are crucial for the analysis and modeling of the activity of scientists. We investigated bibliometric data of papers published in journals of the American... -
Characterizing Interdisciplinarity of Researchers and Research Topics Using W...
Researchers' networks have been subject to active modeling and analysis. Earlier literature mostly focused on citation or co-authorship networks reconstructed from annotated... -
Estimation of Monotone Treatment Effects in Network Experiments
Randomized experiments on social networks pose statistical challenges, due to the possibility of interference between units. We propose new methods for estimating attributable... -
Global multi-layer network of human mobility
Recent availability of geo-localized data capturing individual human activity together with the statistical data on international migration opened up unprecedented opportunities... -
Who is the best player ever? A complex network analysis of the history of pro...
We consider all matches played by professional tennis players between 1968 and 2010, and, on the basis of this data set, construct a directed and weighted network of contacts.... -
Power law distributions of patents as indicators of innovation.
The total number of patents produced by a country (or the number of patents produced per capita) is often used as an indicator for innovation. Here we present evidence that the... -
Identifying Overlapping and Hierarchical Thematic Structures in Networks of S...
We implemented three recently proposed approaches to the identification of overlapping and hierarchical substructures in graphs and applied the corresponding algorithms to a... -
A small world of citations? The influence of collaboration networks on citati...
This paper examines the proximity of authors to those they cite using degrees of separation in a co-author network, essentially using collaboration networks to expand on the... -
Collaboration Networks from a Large CV Database: Dynamics, Topology and Bonus...
Understanding the dynamics of research production and collaboration may reveal better strategies for scientific careers, academic institutions and funding agencies. Here we... -
Are opinions based on science: modelling social response to scientific facts.
As scientists we like to think that modern societies and their members base their views, opinions and behaviour on scientific facts. This is not necessarily the case, even... -
Resampling effects on significance analysis of network clustering and ranking.
Community detection helps us simplify the complex configuration of networks, but communities are reliable only if they are statistically significant. To detect statistically... -
A Computational Approach to Measuring Vote Elasticity and Competitiveness
The recent wave of attention to partisan gerrymandering has come with a push to refine or replace the laws that govern political redistricting around the country. A common... -
Detecting hierarchical and overlapping network communities using locally opti...
Agglomerative clustering is a well established strategy for identifying communities in networks. Communities are successively merged into larger communities, coarsening a... -
Caveat emptor, computational social science: Large-scale missing data in a wi...
As researchers use computational methods to study complex social behaviors at scale, the validity of this computational social science depends on the integrity of the data. On... -
Formation of homophily in academic performance: Students change their friends...
Homophily, the tendency of individuals to associate with others who share similar traits, has been identified as a major driving force in the formation and evolution of social... -
Mathematics of Nested Districts: The Case of Alaska
In eight states, a "nesting rule" requires that each state Senate district be exactly composed of two adjacent state House districts. In this paper we investigate the potential... -
Patterns of Social Influence in a Network of Situated Cognitive Agents
This paper presents the results of computational experiments on the effects of social influence on individual and systemic behavior of situated cognitive agents in a... -
