Network Diversity and Economic Development , Science
Abstract: Social networks form the backbone of social and economic life.
Until recently, however, data have not been available to study the social
impact of a national network structure. To that end, we combined the most
complete record of a national communication network with national census
data on the socioeconomic well-being of communities. These data make
possible a population-level investigation of the relation between the
structure of social networks and access to socioeconomic opportunity. We
find that the diversity of individualsā?? relationships is strongly
correlated with the economic development of communities.

Community Structure in Time-Dependent, Multiscale, and Multiplex
Networks , Science
Abstract: Network science is an interdisciplinary endeavor, with methods
and applications drawn from across the natural, social, and information
sciences. A prominent problem in network science is the algorithmic
detection of tightly connected groups of nodes known as communities. We
developed a generalized framework of network quality functions that
allowed us to study the community structure of arbitrary multislice
networks, which are combinations of individual networks coupled through
links that connect each node in one network slice to itself in other
slices. This framework allows studies of community structure in a general
setting encompassing networks that evolve over time, have multiple types
of links (multiplexity), and have multiple scales.
