The Social Network Approach
  • The world is composed of networks - not
    densely-knit, tightly-bounded groups
  • Networks provide flexible means of social
    organization and of thinking about social
    organization
  • Networks have emergent properties of structure
    and composition
  • Networks are a major source of social capital
    mobilizable in themselves and from their contents
  • Networks are self-shaping and reflexive

4
Social Relations
  • Social relations can be thought of as dyadic
    attributes. Whereas mainstream social science is
    concerned with monadic attributes (e.g., income,
    age, sex, etc.), network analysis is concerned
    with attributes of pairs of individuals, of which
    binary relations are the main kind. Some examples
    of dyadic attributes
  • Kinship brother of, father of
  • Social Roles boss of, teacher of, friend of
  • Affective likes, respects, hates
  • Cognitive knows, views as similar
  • Actions talks to, has lunch with, attacks
  • Distance number of miles between
  • Co-occurrence is in the same club as, has the
    same color hair as
  • Mathematical is two links removed from

5
Social Network Analysis( SNA)
  • Social network analysis is the study of social
    entities (called actors), and their interactions
    and relationships
  • The interactions and relationships can be
    represented with a network or graph
  • each vertex (or node) represents an actor
  • each link represents a relationship
  • From the network, we can study the properties of
    its structure, and the role, and position of each
    social actor
  • We can also find various kinds of sub-graphs,
    e.g., communities formed by groups of actors
  • Set of Connected Units People, Organizations,
    Networks
  • Can Belong to Multiple Networks
  • Examples Friendship, Organizational,
    Inter-Organizational, World-System, Internet

6
Social Network Analysis (SNA)
  • SNA is the mapping and measuring of relationships
    and flows between people, groups, organizations,
    animals, computers, or other information/knowledge
    processing entities
  • The nodes in the network are the people and
    groups while the links show relationships or
    flows between the nodes
  • SNA provides both a visual and a mathematical
    analysis of human relationships
  • A method to understand networks and their
    participants is to evaluate the location of
    actors in the network. Measuring the network
    location is finding the centrality of a node.
    These measures help determine the importance, or
    prominence, of a node in the network. Network
    location can be different than location in the
    hierarchy, or organizational chart
  • We will look at a social network (Kite Network)
    developed by David Krackhardt. Two nodes are
    connected if they regularly talk to each other,
    or interact in some way

7
What is Network Analysis?
  • Network analysis is the study of social relations
    among a set of actors
  • In the process of working in this field, network
    researchers have developed a set of distinctive
    theoretical perspectives as well. Some of the
    hallmarks of these perspectives are
  • focus on relationships between actors rather than
    attributes of actors
  • sense of interdependence a molecular rather
    atomistic view
  • structure affects substantive outcomes
  • emergent effects
  • Network theory is sympathetic with systems theory
    and complexity theory
  • Social networks is also characterized by a
    distinctive methodology encompassing techniques
    for collecting data, statistical analysis, visual
    representation, etc.

8
Data Sources of SNA
  • Questionnaires
  • Direct observation
  • Written records
  • Experiments
  • Affiliations and similarities
  • Online resources

9
Basics of Network Measures
  • Centrality
  • Degree
  • Closeness
  • Betweenness
  • Flow Betweenness
  • Cliques Sub-groups
  • N-cliques
  • N-Clans

Centrality
  • Structural attributes of nodes in a network
    (position)
  • Measure of the contribution of network position
    to the importance, influence, prominence of an
    actor in a network
  • Centralization refers to the extent to which a
    network revolves around a single node

12
Degree Centrality
  • Number of direct ties to others (Row or column
    sums of adjacency matrix)
  • Important or prominent actors are those that are
    linked or involved with other actors extensively
  • A person with extensive contacts (links) or
    communications with many other people in the
    organization is considered more important than a
    person with relatively fewer contacts
  • The links can also be called ties. A central
    actor is one involved in many ties
  • Common wisdom in personal networks is the more
    connections, the better. This is not always so.
    What really matters is where those connections
    lead to -- and how they connect the otherwise
    unconnected

13
Betweenness Centrality
  • If two non-adjacent actors j and k want to
    interact and actor i is on the path between j and
    k, then i may have some control over the
    interactions between j and k
  • Betweenness measures this control of i over
    other pairs of actors. Thus,
  • if i is on the paths of many such interactions,
    then i is an important actor

14
Betweenness Centrality
  • Loosely, the number of geodesic paths that pass
    through a node. The number of times that any
    node need a given node to reach any node by the
    shortest path
  • While Diane has many direct ties, Heather has few
    direct connections -- fewer than the average in
    the network. Yet, in may ways, she has one of the
    best locations in the network -- she is between
    two important constituencies. She plays a
    broker role in the network. The good news is
    that she plays a powerful role in the network,
    the bad news is that she is a single point of
    failure. Without her, Ike and Jane would be cut
    off from information and knowledge in Diane's
    cluster
  • A node with high betweenness has great influence
    over what flows in the network. As in Real
    Estate, the golden rule of networks is
    Location, Location, Location
  • Flow Betweenness Centrality

15
Closeness Centrality
  • The graph-theoretical distance of a given node to
    all other nodes (The sum of the rows/columns of
    the geodesic distance matrix of a graph)
  • Simple closeness is an inverse measure of
    centrality the larger the numbers, the more
    distance an actor is, and the less central
    (farness!)
  • Fernando and Garth have fewer connections than
    Diane, yet the pattern of their direct and
    indirect ties allow them to access all the nodes
    in the network more quickly than anyone else.
    They have the shortest paths to all others --
    they are close to everyone else. They are in an
    excellent position to monitor the information
    flow in the network -- they have the best
    visibility into what is happening in the network

16
Network Centralization
  • Individual network centralities provide insight
    into the individuals location in the network.
    The relationship between the centralities of all
    nodes can reveal much about the overall network
    structure
  • A very centralized network is dominated by one or
    a few very central nodes. If these nodes are
    removed or damaged, the network quickly fragments
    into unconnected sub-networks. A highly central
    node can become a single point of failure. A
    network centralized around a well connected hub
    can fail abruptly if that hub is disabled or
    removed. Hubs are nodes with high degree and
    betweeness centrality
  • A less centralized network has no single points
    of failure. It is resilient in the face of many
    intentional attacks or random failures -- many
    nodes or links can fail while allowing

17
Cliques and Sub-groups
  • Networks are also built up out of the combining
    of dyads and triads into larger, but still
    closely connected sub-structures
  • Many of the approaches to understanding the
    structure of a network emphasize how dense
    connections are compounded and extended to
    develop larger cliques or sub-groupings
  • A clique is simply a sub-set of actors who are
    more closely tied to each other than they are to
    actors who are not part of the group
  • This view of social networks focuses attention on
    how connection of large networks structures can
    be built up out of small and tight components

18
Network Reach
  • Not all network paths are created equal. More and
    more research shows that the shorter paths in the
    network are more important (key paths in networks
    are 1 and 2 steps and on rare occasions, three
    steps)
  • The small world we live is not one of "six
    degrees of separation" but of direct and indirect
    connections lt 3 steps away. Therefore, it is
    important to know who is in your network
    neighborhood? Who are you aware of, and who can
    you reach?
  • In the Kite Network, who is the only person that
    can reach everyone else in two steps?

19
Boundary Spanners
  • Nodes that connect their group to others usually
    end up with high network metrics. Boundary
    spanners such as Fernando, Garth, and Heather are
    more central than their immediate neighbors whose
    connections are only local, within their
    immediate cluster
  • Boundary spanners are well-positioned to be
    innovators, since they have access to ideas and
    information flowing in other clusters. They are
    in a position to combine different ideas and
    knowledge, found in various places, into new
    products and services

20
Peripheral Players
  • Most people would view the nodes on the periphery
    of a network as not being very important. In
    fact, Ike and Jane receive very low centrality
    scores for this network. Yet, peripheral nodes
    are often connected to networks that are not
    currently mapped. Ike and Jane may be contractors
    or vendors that have their own network outside of
    the company -- making them very important
    resources for fresh information not available
    inside the organization!

SNA Software (UCINET)
  • UCINET is a comprehensive software program for
    the analysis of social networks
  • The program contains several network analytic
    routines (e.g., centrality measures, dyadic
    cohesion measures, positional analysis
    algorithms, and clique etc.), and general
    statistical and multivariate analysis tools such
    as multidimensional scaling, correspondence
    analysis, factor analysis, cluster analysis, and
    multiple regression

Questions for Communities Based on Network
Analysis
  • Which community agencies or groups are most (and
    least) central in the network, and are these
    agencies or groups essential for addressing
    community needs in a particular problem area?
  • Which core network members have links to
    important resources through their involvement
    with organizations outside the network that might
    benefit other network members?
  • Are the critical ties among agencies in the
    community based solely on personal relationships,
    or have these ties become formalized so that they
    are sustainable over time?
  • Are the relationships among agencies in the
    network strong or weak? If they are weak, should
    these relationships be maintained as is, or
    should they be strengthened?
  • Which groups of organizations within the network
    currently have strong working relationships? How
    can these groups be mobilized to meet the broader
    objectives of the network?
  • Based on comparative network data over time, has
    reasonable progress been made in building
    community capacity through developing stronger
    network ties?
  • What is the level of trust among agencies working
    together, and has it increased or decreased over
    time? If it has declined, how can it be
    strengthened?
  • What are the benefits and drawbacks of
    collaboration, have these changed over time, and
    how can benefits be enhanced and drawbacks
    minimized?

Conclusion
  • Information generated through SNA will have
    practical value if it effectively presented,
    discussed, accepted, and acted on by network
    participants
  • SNA can be a valuable tool for helping community
    leaders (network members) to understand network
    structure and processes
