Three Ways to Look at Reality
  • Categories
  • All Possess One or More Properties as an
    Aggregate of Individuals
  • Examples Men, Developed Countries
  • Groups
  • (Almost) All Densely-Knit Within Tight Boundary
  • Thought of as a Solidary Unit (Really a Special
  • Family, Workgroup, Community
  • Networks
  • Set of Connected Units People, Organizations,
  • Can Belong to Multiple Networks
  • Examples Friendship, Organizational,
    Inter-Organizational, World-System, Internet

Nodes, Relationships Ties
  • Nodes A Unit That Possibly is Connected
  • Individuals, Households, Workgroups,Organizations,
  • Relationships (A Specific Type of Connection) A
    Role Relationship
  • Gives Emotional Support
  • Sends Money To
  • Attacks
  • Ties (One or More Relationships)
  • Friendship (with possibly many relationships)
  • Affiliations (Person Organization)
  • Works for IBM INSNA Member Football Team
  • One-Mode, Two-Mode Networks

A Network is More Than The Sum of Its Ties
  • A Network Consists of One or More Nodes
  • Could be Persons, Organizations, Groups, Nations
  • Connected by One or More Ties
  • Could be One or More Relationships
  • That Form Distinct, Analyzable Patterns
  • Can Study Patterns of Relationships OR Ties
  • Emergent Properties (Simmel vs. Homans)

In a Sentence
  • To Discover How A, Who is in Touch with B and C,
    Is Affected by the Relation Between B C

  • Automated Data Collection

The Multiple Ways of Network Analysis
  • Method The Most Visible Manifestation
  • Misleading to Confuse Appearance with Reality
  • Data Gathering see previous slide
  • Theory Pattern Matters
  • Substance
  • Community, Organizational, Inter-Organizational,
    Terrorist, World System
  • An Add-On
  • Add a Few Network Measures to a Study
  • Integrated Approach
  • A Way of Looking at the World
  • Theory, Data Collection, Data Analysis,
    Substantive Analysis
  • Not Actor-Network Theory
  • Links to Structural Analyses in Other Disciplines

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
  • 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
  • Networks scale up to networks of networks

The Social Network Approach
  • Moving from a hierarchical society bound up in
    little boxes to a network and networking
  • Multiple communities / work networks
  • Multiplicity of specialized relations
  • Management by networks
  • More alienation, more maneuverability
  • Loosely-coupled organizations / societies
  • Less centralized
  • The networked society

Changing ConnectivityGroups to Networks
  • Densely Knit gt Sparsely-Knit
  • Impermeable (Bounded) gt Permeable
  • Broadly-Based Solidarity gt Specialized Multiple

Networked Individualism
  • Moving from a society bound up in little boxes to
    a multiple network and networking society
  • Networks are a flexible means of social
  • Networks are a major source of social capital
    mobilizable in themselves from their contents
  • Networks link
  • Persons
  • Within organizations
  • Between organizations and institutions

Little Boxes ? Ramified Networks
  • Each in its Place ? Mobility of People and
  • United Family ? Serial Marriage, Mixed Custody
  • Shared Community ? Multiple, Partial Personal
  • Neighborhoods ? Dispersed Networks
  • Voluntary Organizations ? Informal Leisure
  • Face-to-Face ? Computer-Mediated
  • Public Spaces ? Private Spaces
  • Focused Work Unit ? Networked Organizations
  • Job in a Company ? Career in a Profession
  • Autarky ? Outsourcing
  • Office, Factory ? Airplane, Internet,
  • Ascription ? Achievement
  • Hierarchies ? Matrix Management
  • Conglomerates ? Virtual Organizations/Alliances
  • Cold War Blocs ? Fluid, Transitory Alliances

Ways of Looking at Networks
  • Whole Networks Personal Networks
  • Focus on the System or on the Set of Individuals
  • Graphs Matrices
  • We dream in graphs
  • We analyze in matrices

Whole Social Networks
  • Comprehensive Set of Role Relationships in an
    Entire Social System
  • Analyze Each Role Relationship Can Combine
  • Composition Women Heterogeneity Weak Ties
  • Structure Pattern of Ties
  • Village, Organization, Kinship, Enclaves,
  • Copernican Airplane View
  • Typical Methods Cliques, Blocks, Centrality,
  • Examples (1) What is the Real Structure of an
  • (2) How Does Information Flow Through a Village?

Cumulative GlobeNet Intercitation Through 2000
Howard White Barry Wellman, 2003 Does
Citation Reflect Social Structure
Strongest Globenet Co-Citation, Intercitation
Links Thru 2000
Duality of Persons Groups
  • People Link Groups
  • Groups Link People
  • An Interpersonal Net is an Interorganizational
  • Ronald Breiger 1973

The Dualities of Persons and Groups -- Graphs
Dualities of Persons and Groups -- Matrices
Dualities of Persons and Groups Event-Event
Neat Whole Network Methods
  • QAP
  • Regression of Matrices
  • Example Co-Citation (Intellectual Tie)
  • Predicts Better than Friendship (Social Tie)
  • To Inter-Citation
  • Clustering High Density Tight Boundaries
  • Block Modeling
  • Similar Role Relationships, Not Necessarily
  • Canada Mexico in Same Block US Dominated

Erickson, 1988 From a Matrix gt . . .
. . . To a Block Model
Costs of Whole Network Analysis
  • Requires a Roster of Entire Population
  • Requires (Imposition of) a Social Boundary
  • This May Assume What You Want to Find
  • Hard to Handle Missing Data
  • Needs Special Analytic Packages
  • Becoming Easier to Use

Personal Social Networks
  • Ptolemaic Ego-Centered View
  • Good for Unbounded Networks
  • Often Uses Survey Research
  • Example (1) Do Densely-Knit Networks Provide
    More Support? (structure)
  • (2) Do More Central People Get More Support?
  • (network)
  • (2) Do Women Provide More Support? (composition)
  • (3) Do Face-to-Face Ties Provide More Support
    Than Internet Ties? (relational)
  • (4) Are People More Isolated Now? (ego)

Costs of Personal Network Studies
  • Concentrates on Strong Ties
  • Collecting Proper Data in Survey Takes Much Time
  • Ignores Ecological Juxtapositions
  • Hard to Aggregate from Personal Network to Whole
  • Easier to Decompose Whole Network
  • (Haythornthwaite Wellman)
  • Often Relies on Respondents Reports

Social Network Analysis More Flavors
  • Diffusion of Information ( Viruses)
  • Flows Through Systems
  • Organizational Analyses
  • Real Organization
  • Knowledge Acquisition Management
  • Inter-Organizational Analysis
  • Is There a Ruling Elite
  • Strategies, Deals
  • Networking How People Network
  • As a Strategy
  • Unconscious Behavior
  • Are There Networking Personality Types?

SNA Branching Out
  • Social Movements
  • World-Systems Analyses
  • Cognitive Networks
  • Citation Networks
  • Co-Citation
  • Inter-Citation
  • Applied Networks
  • Terrorist Networks
  • Corruption Networks

Multilevel AnalysisNew Approach to an Old
  • Switching and Combining Levels
  • Individual Agency, Dyadic Dancing, Network
    Facilitation Emergent Properties
  • Consider Wider Range of Theories
  • Disentangles ( Avoids Nagging Confounding)
  • Tie Effects
  • Network Effects
  • Contingent (Cross-Level) Effects
  • Interactions
  • Addresses Emergent Properties
  • Fundamental Sociological Issue
  • Simmel vs. Homans

Multilevel Analysis Tie Effects
  • Tie Strength Stronger is More Supportive
  • Workmates Provide More Everyday Support
  • (Multilevel Discovered This)

Multilevel Analysis Network Effects
  • Network Size
  • Not Only More Support from Entire Network
  • More Probability of Support from Each Network
  • Mutual Ties (Reciprocity)
  • Those Who Have More Ties with Network Members
    Provide More Support
  • Cross-Level Effect Stronger (and Attenuates)
  • Dyadic (Tie-Level) Effect
  • Its Contribution to the Network, Not the Alter

Multilevel AnalysisCross-Level, Interaction
  • Kinship
  • No longer a solidary system
  • Parent-(Adult) Child Interaction
  • More Support From Each When gt 1 Parent-Child Tie
  • Single P-C Tie 34
  • 2 P-C Ties, Probability of Support from Each 54

Multilevel Interactions-- Accessibility
  • 37 of Moderately Accessible Ties
  • Provide Everyday Support
  • But If Overall Network Is
  • Moderately Supportive,
  • 54 of All Network Members
  • Provide Everyday Support
  • Women More Supportive
  • In Nets with More Women

The Internet in Everyday Life
  • Computer Networks as Social Networks
  • Key Questions
  • Community On and Off line
  • Networked Life before the Internet
  • Netville The Wired Suburb
  • Large Web Surveys National Geographic
  • Work On and Off line
  • Towards Networked Individualism, or
  • The Retreat to Little Boxes

Social Affordances of New Forms of
Computer-Mediated Connectivity
  • Bandwidth
  • Ubiquity Anywhere, Anytime
  • Convergence Any Media Accesses All
  • Portability Especially Wireless
  • Globalized Connectivity
  • Personalization

Research Questions
  1. Ties Does the Internet support all types of
  2. Weak and Strong?
  3. Instrumental and Socio-Emotional?
  4. Online-Only or Using Internet Other Media (F2F,
  5. Social Capital Has the Internet increased,
    decreased, or multiplied contact at work, in
  6. Interpersonally Locally
  7. Interpersonally Long Distance
  8. Organizationally
  9. GloCalization Has the map of the world dissolved
    so much that distance does not matter? Has the
    Internet brought spatial and social peripheries
    closer to the center?

Research Questions (contd)
  • Structure Does the Internet facilitate working
    in loosely-coupled networks rather than dense,
    tight groups?
  • Knowledge Management How do people find and
    acquire usable knowledge in networked and virtual

Guiding Research Principles
  • Substitute systematic data analysis for hype
  • Do field studies, not lab experiments
  • Combine statistical with observational info.
  • Study the use of each media in larger context
  • Work with other disciplines
  • Analyze Existing Uses
  • Develop New Uses

  • And are Invited by Them
  • Neighbor in a Wider Area

Long-Distance Ties (gt50 km/30 mi )
  • Compared to one year before moving to Netville,
  • Wired Residents Have More Than Non-Wired
  • Social Contact especially over 500 km
  • Help Given (e.g., childcare, home repair)
  • Help Received from Friends and Relatives
  • Especially between 50 and 500 km

Long-Distance Ties

  • How do Work, Social Roles Affect Media Use?
  • Is Email Used Only for Specialized Communication?
  • Does Email Use
  • Replace, Add To, or Increase F2F, Phone
  • Does Email Move Spatial/Social Peripheries
    Socially Closer?
  • Does Email Foster Networked Organization?

Separate Information Exchange Roles Derived from
Factor Analysis of Specific Exchanges
  • Work
  • Giving Work
  • Receiving Work
  • Collaborative Writing
  • Computer Programming
  • Social
  • Sociability
  • Major Emotional Support

Communication Roles
  • Scheduled Meetings
  • Classes, Research Meetings
  • Email
  • Unscheduled Meetings
  • Less Frequent, More Wide-Ranging
  • Media that Afford Control of Interactions
  • Media associated with Group Norms

Social Roles
  • Sociability, major emotional support

Comparison of 2 Scholarly Networks
Globenet Technet
Year Founded Founded in 1991-93 Founded in 1995-96
Size 16 (13 men, 3 women) 32 (22 men, 9 women)
Membership Invitational merit, interdisciplinary, niche Voluntary
Location Canada, US, UK 1 Ontario university
Activities 3 Meetings /year Production of a book Frequent seminars, conferences Joint courses, retreats
Funding 9 Senior Fellows get full salaries 7 Associate Fellows get partial funding Members not funded by Technet Many receive other research grants
  • Globenet members use both F2F email to get
    their joint projects done. The dispersion of
    members across Canada, U.S. U.K. leads them to
    use email as a collaborative tool.

  • .
  • For Globenetters, the distance between members of
    scholarly pairs is unrelated to the frequency of
    their email contact.
  • Except when theyre in the same building

  • Friendship is the strongest predictor to
    face-to-face email contact in Technet Globenet

  • The scholarly relationship of collaborating on a
    project is the second strongest predictor of
    frequent F2F contact frequent email contact.
  • It friendship are the only 2 significant

  • Congruent with the theories of media use Tasks
    requiring complex negotiations preferably
    conducted via richer F2F contacts.
  • Technet members use F2F contact when possible.
  • Email fills in temporal informational gaps.
    Those Technet members who often read each others
    work, communicate more by email.

  • Where F2F contact is easily done, it is the
    preferred medium for collaborative work.
  • However, colleagues easily share their ideas and
    their work or announce its existence by email
    and web postings.
  • They do not have to walk over to each others
    offices to do this, although Canadian winters can
    inhibit in-person visits

Sources of Prominence in Globenet
  • External Sources Important for Gaining Entrance
  • Scholarly Status
  • Niche
  • Plus Perceived Internal Congeniality
  • Internal Sources Important Within Network
  • Knights of the Roundtable
  • Formal Role
  • Scholarly Communication within Network
  • Number of Friendships

    Email Adds On to Same Levels of F2F, Phone1.
    Friends More than Kin2. Long-Distance Ties More
    than Local3. Post Used Only for Rituals
    (Birthdays, Christmas)
  • Evidence National Geographic, Netville

SummaryComputer-Mediated Communication
  • Not only supports online virtual communities
  • Supports and maintains existing ties strong
  • Increases connectivity with weak ties
  • Supports both local and non-local social ties
  • In Neighborhood, High-speed Network
  • Increases local network size
  • Increases amount of local contact
  • Long-Distance, High-Speed Network
  • Increases amount of contact
  • Increases support exchanged
  • Facilitates contact with geographical periphery

Summary The GloCalization Paradox
  • Surf and Email Globally
  • Stay Wired at Office/Home to be Online
  • Desire for Local/Distant Services and Information
  • Internet Supplements/Augments F2F
  • Doesnt Replace It
  • Rarely Used Exclusively
  • Media Choice? By Any Means Available
  • Many Emails are Local Within the Workgroup
    or Community
  • Local Becomes Just Another Interest
  • Evidence Netville, National Geographic, Small
    Cities, Berkeley, Netting Scholars, Cerise,
    Indigo, Telework

Summary Social Network Structure
  • Internet Aids Both Direct Indirect Connections
  • Knowledge Acquisition Management
  • Accessing Friends of Friends
  • Forwarding Folding In Making Indirect Ties
    Direct Ties
  • Social and Spatial Peripheries Closer to the
  • Shift from Spatial Propinquity to Shared
  • Shifting, Fluid Structures
  • Networked, Long-Distance Coordination Reports

Conclusions Changing Connectivity
  • By Any Means Available
  • Door-to-Door gt Place-to-Place gt
    Person-to-Person Connectivity
  • Less Solidary Households
  • Dual Careers
  • Multiple Schedules
  • Multiple Marriages
  • New Forms of Community
  • Partial Membership in Multiple Communities
  • Networked Virtual Work Relationships

ConclusionsRole-to-Role Relationships
  • Partial Communities of Shared, Specialized
  • Importance of Informal Network Capital
  • Production
  • Reproduction
  • Externalities
  • Bridging and Bonding Ties

ConclusionsHow a Network Society Looks
  • Multiplicity of Specialized Relations
  • Management by Networks
  • More Uncertainty, More Maneuverability
  • Boutiques, not General Stores
  • Less Palpable than Traditional Solidarities
  • Need Navigation Tools
  • An Electronic Group is Virtually a Social

Conclusions Shift to New Kinds Of Community
  • Partial Membership in Multiple Networks
  • Multiple Reports
  • Long-Distance Relationships
  • Transitory Work Relationships
  • Each Person Operates Own Network
  • Online Interactions Linked with Offline
  • Status, Power, Social Characteristics Important
  • Sparsely-Knit Fewer Direct Connections Than
    Door-To-Door -- Need for Institutional Memory
    Knowledge Management
  • IKNOW (Nosh Contractor) Network Tracer
  • ContactMap (Bonnie Nardi Steve Whittaker)
    Network Accumulator

Conclusions The Rise of Personalized Networking
  • Individual Agency Constrained by Nets
  • Personalization rather than Group Behavior
  • Interpersonal Ties Dancing Dyadic Duets
  • Bandwidth
  • Sparsely-Knit, Physically-Dispersed Ties
  • Social Networks
  • Multiple, Ad Hoc
  • Wireless Portability

Design Considerations for a Networked Society
  • Open List
  • Indicate Presence, Awareness, Availability
  • Prioritize from Deductive, Inductive Ad Hoc
  • Prioritize by Locale
  • Searchable and Sortable List
  • By a Variety of Attributes

Design Considerations for a Networked Society
  • Incorporate Third Parties
  • Quickly Set Up Dissolve Work Teams
  • Privacy Protection
  • Control Who is Aware of the Interaction
  • Alert if Others Lurking
  • File Access
  • Cross-Platform Communication

Awareness and Availability All visible and audible to all High awareness of availability Core immediately visible, audible Little awareness of others availability -- must be contacted Little awareness of availability Must be contacted Visibility and audibility must be negotiated
Access Control Doors wide open to in-group membersWalled off from othersExternal gate guarded Doors ajar within and between networks Look, knock and ask Doors closed Access to others by requestKnock and ask
Physical Access All have immediate access to all Core have immediate accessContacting others requires a journey or telecommunications Contact requires a journey or telecommunications
Permeability Impermeable wall around unit Household and workgroup have strong to weak outside connections Individual has strong to weak connections
Boundaries (continued)
Phenomena Little Boxes Glocalization Networked Individualism
Interruptibility High (Open Door) Norm of Interruption Mixed Core interruptibleOthers require deliberate requestsAnswering machineKnocking on door that may be ajar or closedNorm of Interruption within immediate network only Low Contact must be requested May be avoided or refusedPrioritizing voice mailInternet filterKnocking on door that may be ajar or closedNorm of interruption within immediate network only
Observability High All can see when other group members are interacting Mixed Core can observe core Periphery cannot observe core or interactions with other network members Low Interactions with other network members rarely visible
Privacy Low information control Few secretsStatus/Position becomes important capital Low information controlFew secrets for coreVariable information control for peripheryMaterial resources and network connections become important capital High information controlMany secrets Information and ties become important capital
Joining In Anyone can observe interactionsAnyone can join Interactions outside the core rarely observable Difficult to join Interactions rarely observable Difficult to join
Alerts Little awareness of others approaching Open, unlocked doors High prior awareness of peripherys desire to interact Telephone ring, doorbell High prior awareness of others desire to interactFormal requests

Knowledge All aware of most information Information open to all within unit Secret to outsiders Core Knows Most Things Variable awareness of and access to what periphery knows Variable awareness of and access to what periphery knows
Social Control Superiors and group exercise tight control Moderate control by core household and workgroup, with some spillover to interactions with periphery Fragmented control within specialized networks Adherence to norms must be internalized by individuals Subgroups, cleavages Partial, fragmented control within specialized networksAdherence to norms must be internalized by individuals
Resources Conserves resources Acquires resources for core units Acquires resources for self

Norms and Perceptions
Phenomena Little Boxes Glocalization Networked Individualism
Socialization Obey group elders Obey your parents cherish your spouse nurture your childrenDefer to your boss work and play well with colleagues and friends Develop strategies and tactics for self-advancement
Sense of Solidarity High group solidarityCollective identityCollective name Moderate solidarity within core household and workgroup, Vitiated by many ties to multiple peripheries Sense of being an autonomous individualFuzzy identifiable networks
Loyalty Particularistic High group loyalty Public and private spheres Moderate loyalty to home base takes precedence over weak loyalty elsewhere SelfGlobal weak and divided loyalties
