analyses of political, economic and other institutions. Granovetter examines how social
structures and social networks can affect economic outcomes like hiring, price,
productivity and innovation and describes sociologists' contributions to analyzing the
impact of social structure and networks on the economy.
Health Care
Analysis of social networks is increasingly incorporated into health care analytics, not
only in epidemiological studies but also in models of patient communication and
education, disease prevention, mental health diagnosis and treatment, and in the study
of health care organizations and systems.
Human Ecology
Human ecology is an interdisciplinary and transdisciplinary study of the relationship
between humans and their natural, social, and built environments. The scientific
philosophy of human ecology has a diffuse history with connections
to geography, sociology, psychology, anthropology, zoology, and natural ecology.
Language and Linguistics
Studies of language and linguistics, particularly evolutionary linguistics, focus on the
development of linguistic forms and transfer of changes, sounds or words, from one
language system to another through networks of social interaction. Social networks are
also important in language shift, as groups of people add and/or abandon languages to
their repertoire.
Literary Networks
In the study of literary systems, network analysis has been applied by Anheier,
Gerhards and Romo, De Nooy, and Senekal, to study various aspects of how literature
functions. The basic premise is that polysystem theory, which has been around since
the writings of Even-Zohar, can be integrated with network theory and the relationships
between different actors in the literary network, e.g. writers, critics, publishers, literary
histories, etc., can be mapped using visualization from SNA.
Organizational Studies
Research studies of formal or informal organization relationships, organizational
communication, economics, economic sociology, and other resource transfers. Social
networks have also been used to examine how organizations interact with each other,
characterizing the many informal connections that link executives together, as well as
associations and connections between individual employees at different
organizations. Intra-organizational networks have been found to affect organizational
commitment, organizational identification, interpersonal citizenship behavior.
