Журналы
Social Networks is an interdisciplinary and international quarterly. It
provides a common forum for representatives of anthropology, sociology,
history, social psychology, political science, human geography, biology,
economics, communications science and other disciplines who share an
interest in the study of the empirical structure of social relations and
associations that may be expressed in network form. It publishes both
theoretical and substantive papers. Critical reviews of major theoretical or
methodological approaches using the notion of networks in the analysis
of social behaviour are also included, as are reviews of recent books
dealing with social networks and social structure.
Network Science is a new journal for a new discipline - one using
the network paradigm, focusing on actors and relational linkages, to
inform research, methodology, and applications from many fields
across the natural, social, engineering and informational sciences.
Given growing understanding of the interconnectedness and
globalization of the world, network methods are an increasingly
recognized way to research aspects of modern society along with
the individuals, organizations, and other actors within it.
The discipline is ready for a comprehensive journal, open to papers
from all relevant areas. Network Science is a defining work,
shaping this new discipline. The journal welcomes contributions from
researchers in all areas working on network theory, methods, and
data.
