What is a network for .
Social scientists A social network is a
description of the social structure between
actors, mostly individuals or organizations. It
indicates the ways in which they are connected
through various social familiarities ranging
from casual acquaintance to close familial bonds.
The term was first coined in 1954 by J. A.
Barnes (in Class and Committees in a Norwegian
Island Parish, "Human Relations").
http//en.wikipedia.org/wiki/Social_network
Actors and their actions are viewed as
interdependent rather than independent,
autonomous units. Relational ties (linkages)
between actors are channels for transfer or
flowof resources Network models focusing on
individuals view the network structural
environment as providing opportunities for or
constraints on individual action. Network models
conceptualize structure (social, economic,
political , and so forth) as lasting patterns of
relations among actors (Wassermann, Faust, p.4)

What is a network for
  • Economists
  • The network effect causes a good or service to
    have a value to a potential customer dependent on
    the number of customers already owning that good
    or using that service. Metcalfe's law states that
    the total value of a good or service that
    possesses a network effect is roughly
    proportional to the square of the number of
    customers already owning that good or using that
    service.
  • One consequence of a network effect is that the
    purchase of a good by one individual indirectly
    benefits others who own the good - for example by
    purchasing a telephone a person makes other
    telephones more useful. This type of side-effect
    in a transaction is known as an externality in
    economics, and externalities arising from network
    effects are known as network externalities. This
    is also an example of a positive feedback loop.
  • http//en.wikipedia.org/wiki/Network_externality
  • Interaction and the networks through which it
    operates are important in determining aggregate
    economic phenomena and and that this allows us to
    start from more plausible models of individuals
    If this is accepted, then we must first
    understand how networks influence aggregate
    outcomes. The next step is to understand how
    these networks form and if, and why, they
    persist. (Kirman, Handbook, 274)

What is a network for
  • Physicists
  • Complex networks are the backbone of a complex
    system. They are special
  • networks at the edge of chaos where the degree of
    connectivity is neither
  • regular nor random. The most complex networks of
    the real world are either
  • small-world networks or scale-free networks at
    the border between regular and
  • random networks, between order and randomness.
  • http//en.wikipedia.org/wiki/Complex_network
  • Recent results on the topology of real networks
    indicate the emergence of a new paradigm the
    apparent randomness of complex systems with many
    degrees of freedom hides generic mechanisms and
    order that are crucial to the understanding of
    the interwoven world surrounding us. (Barabasi,
    Handbook, p. 69)
  • Mathematicians
  • In mathematics, a network is usually called a
    graph.
  • http//en.wikipedia.org/wiki/NetworkMathematics

Struggle among disciplines
  • In all the recent discussions about the
    relationship between physics and sociology in the
    study of social networks, the fundamental issue
    seems to have been lost sight of. The important
    issue is not whether the two disciplines can or
    should cooperate. That is essential and it
    happens frequently. Contributors to the
    discussion have pointed out many fruitful and
    important cases, and the history of sociology is
    full of many others. The big problem arises when
    academics from one discipline move into the area
    of another discipline without trying to discover
    what work has already been done by its
    practitioners. At best they reinvent the wheel.
    At worst they antagonise people with their
    intellectual arrogance.
  • This is what has happened with much of the recent
    work on small worlds physicists have argued that
    their methods and theories can illuminate social
    networks but have failed to realise that a whole
    community of sociological network researchers
    already exists and has done exactly the kind of
    work that they are pointing to. Their books claim
    to have made startling discoveries about the
    social world and advocate the development of new
    research programmes on these topics. Their
    reviewers take these claims at face value and so
    a reputation for intellectual novelty is built
    up.
  • It is surely a basic failure of normal scholarly
    research procedures that these books can be
    written and published without the author
    undertaking any proper literature search. The
    author of one recent book expounding the novelty
    of the 'power law' does not seem to realise that
    sociological work over many years has documented
    the existence of this kind of distribution in
    many real social networks. None of this is cited.
    Its author does not seem to have discovered the
    existence of journals on social networks, nor
    does he seem to realise that INSNA exists and
    that the cover design of its newsletter shows a
    network with a power law structure. This same
    book is based around the author's research into
    internet search engines, but it doesn't seem as
    if he has ever typed the words 'social networks'
    into Google or any other search engine.
  • If I were to come up with the idea that familiar
    theories from sociology could illuminate problems
    in physics, the first thing I would do would be a
    literature search to see if anybody, in physics
    or elsewhere, had already worked on the issue.
    Physicists who followed the same strategy when
    they wished to contribute something to social
    analysis, might find that they would be welcomed
    more warmly by their social science colleagues.

Network as a metaphor
  • Our aim is to trace different notions of a
    network in a metaphorical sence across domains of
    use
  • We argue that by triangulating various approaches
    to network as a metaphor, we are able to shed
    light on the different underlying theoretical and
    methodological assumptions that sometimes block
    the possibly fruitful interaction between the
    different research traditions.
  • The metaphor of network functions as circulating
    device (boundary object) across different domains
    of use

9
Metaphor research
  • Metaphors are dynamic and flexible tools of
    translation between different domains
  • Metaphors often provide a common ground
    concerning terminology and knowledge
  • In science they might function as heuristic
    devices helping to generate novel ideas.
  • Metaphors as (stable) units of circulation
    between discourses vs. Metaphors as (dynamic)
    units changing discourses

10
Metaphors in science
  • Open up common ground for debates (even if the
    participants of such a debate do not always agree
    on the meanings of the metaphor) and triggers
    interdisciplinary discussions
  • Can be traced by systematically discussing which
    elements of the metaphor are used in the
    different domains of use.
  • Are used in the emergence of new ideas (trading
    zone).

11
Network as metaphor
  • To be able to trace network as a metaphor we
    will look at the context and the purpose with
    which network functions as a place holder for
    different conceptual approaches.
  • We will discuss the advantages and the
    limitations of the use of the network in
    different sc. disciplines or domains of use.
  • We will introduce dimensions/characteristics of
    the metaphor network.
  • We will use these dimensions to differentiate
    between the different approaches but also to
    point to possible cross sections between them.

12
How to map the different concepts?
Network as a constraint for other dynamic
processes (dynamics on networks, dynamics of
networked agents)
Network evolution as a result of individual
actions
Network topology as a characteristics of the
function of the system
Network as a collective phenomena of individual
actions
Network as a constraint/enabling for individuals

Linked metaphors What is an innovation?
  • ECONOMICS/SOCIAL SCIENCES
  • Innovation is the implementation of a new or
    significantly improved idea, good, service,
    process or practice which is intended to be
    useful.
  • Invention/innovation, radical and incremental
    innovations, process and product innovation,
    competition and logistic growth

15
Linked metaphors What is an innovation?
  • SYSTEMS THEORY
  • Innovation is a critical event which
    destabilizes the current state of the system and
    opens a new process of self-organization leading
    to a new stable state
  • The definition of an innovation bases on the
    definietion of the borders of the systems
    (innovation in a firm, innovation in a market),
    also the emergence of new scientific specialties,
    new streams of communication, new ways of
    behaviour are systemic innovations.

16
Linked metaphors Network and innovation ?
  • A part of a network?
  • A new node or a new link?
  • A new node which destabilizes the whole network
    (critical event or sensitive networks)?
  • A product/outcome of a network?
  • Which type of network?
  • Which type of relations building the network?
  • An event of a dynamics taking place on a network
    topology?
  • Epidemics on networks -gt Criteria for success
  • Innovations triggering dynamical processes on
    networks as critical event
  • Which types of network topologies support
    innovations?

17
Conclusions 1
  • Metaphors can be used to trace the development of
    new specialties and cross-disciplinary
    communications.
  • The network metaphor focuses the attention to the
    complexity between the parts and the whole. It
    also allows to address the dualism between
    structure and action.
  • While analysing the different context of the
    network metaphor we determine dimensions of the
    metaphor in a multidimensional space of meanings.

18
Conclusions 2
  • Triangulation in the metaphor space allows to
    point to hot spots and blind spots in the
    scientific uses of the network metaphor.
  • Semantic maps combined with bibliometric analysis
    (frequency of occupation of areas in the metaphor
    space) could be a tool to make the space visible.
