11
The attributes of a variable
  • Name (an identifier)
  • Scope (research question and boundaries)
  • Definition
  • Data (relevant information)
  • Causality (dependencies)
  • Unit
  • Formula (how to compute based on the above)
  • Result (what is the current estimate/answer to
    the research question?)

12
The attributes of a variable
13
Connections between variable attributes

14
Parts of an attribute
  • Actual content what is known
  • Narrative description any explanations or
    background information that is useful to
    understand the actual content
  • Discussion (formal) discussions about the actual
    content

15
What is the acceptability of the idea of open
assessment?
  • Poll (informal, based on observations of several
    audiences)
  • 30 think it is a stupid idea
  • 50 think it cannot work
  • 15 find it interesting, but
  • 5 are fond of the idea
  • In which category do you fall in?

16
Interfaces between tools
  • Opasnet Open website for any assessment-related
    descriptions (en.opasnet.org, fi.opasnet.org)
  • Erac website A project website for Finmerac
    material (to be extended to other projects)
  • Analytica modelling software (Monte Carlo,
    causal diagrams and models. www.lumina.com)
  • Models uploaded to Opasnet
  • Computing in Analytica, descriptions in Opasnet.
  • Result base Interpreted results in a
    model-friendly format (www.pyrkilo.fi/resultdb,
    soon base.opasnet.org)
  • M-files For original and processed data (FMS)

17
Lessons learnt
  • Finmerac was not originally planned as an open
    assessment. This caused confusion when the way of
    working changed during project.
  • Researchers not experienced in OA or wiki
    reluctance to use.
  • Difficulties in finding the role and place of own
    work.
  • The role was only found when the assessment
    structure became clear enough

19
What are the challenges of the current risk
assessment?
  • Limited area of application
  • Lack of flexibility and breadth
  • Inefficiency and slowliness of the process
  • Deliberate biases towards "safety"
  • Communication problems
  • Lack of acceptability among stakeholders

20
What is needed from the new assessment?
21
Paradigm shift
  • Thomas Kuhn (1922-1996)?
  • Science progresses in a regular way until too
    many faults are identified in the current
    paradigm. Then, there is a period of
    extraordinary science, which leads into a shift
    of paradigm

22
Open assessment
  • The objectives
  • Find solutions to ALL the challenges at the same
    time
  • Systematize and "industrialize" the risk
    assessment
  • Maintain high scientific quality
  • The current situation with open assessment there
    are suggested methods to all challenges listed
    previously
  • Many of the suggestions have not been tested in
    practice
  • Not everything will probably work
  • ?However, there is already a critical mass of
    solutions available so that full-scale testing
    can be started
  • ?Further problems should be solved as they appear

23
Assessments in practice
  • They look like Wikipedia articles
  • They are written in much the same way
  • Substance is on the main page
  • Research question
  • Definition how to find an answer
  • Result
  • Discussion about the substance is on a separate
    discussion page
  • Discussion can be free or structured

24
Open assessment
  • The research question for the (pyrkilo) method
  • "How can scientific information and value
    judgements be organised for societal
    decision-making in such a way that open
    participation is possible?"
  • Full range of development
  • a new ontological foundation
  • strictly object-oriented approach
  • a new structure for information objects
  • traditional RA methods for processing
    information, but organised in a more systematic
    way
  • tools that enable open collaboration
  • data sources that are directly available and
    applicable

25
Highlights of the theory behind
  • The basic principles are
  • Open participation at all phases of the
    assessment
  • Requirement of scientific method (openness to
    scientific critique) at all phases
  • Reusability of information from one assessment to
    another
  • A uniform information structure is used
  • Assessment specific information need for a
    policy decision
  • Variable a truthful description of a particular
    part of reality it is independent of assessments
    given its scope.
  • Both objects have 4 attributes name, scope
    (research question), definition (how to answer),
    and result

26
Assessments are performed openly in the Internet
  • Parts needed to run open assessments
  • Web pages with method descriptions for the
    assessors (Guidebook)
  • Web pages about useful data (Resource Centre)
  • Web pages about actual assessments
  • Descriptions of assessments and models used
    (Warehouse)
  • Actual models (Toolbox)
  • Results of assessments in a uniform structure
    (Result database)
  • Web pages for collaborative work on assessments
    (Collaborative workspace)
  • Red parts are officially parts of the Intarese
    project

27
Quality control
  • Is quality control possible if pages are
    available for all to contribute?
  • Our first thoughts (no experience yet, because
    work is practically within research projects)
  • Pages can be freely added and edited
  • Advanced pages are protected from direct edits
  • Then, the edits are made through an open
    discussion on a separate page results are
    transferred to the actual page
  • Very important pages go through a peer review and
    get a quality label

28
The ORA report
29
Falsification
  • Karl Popper (1902-1994)?
  • Science consists of statements (theories) that
    can be falsified
  • Science is an evolutionary process where poor
    theories are falsified
  • The current knowledge consists of those theories
    that have not (yet) been falsified

30
Argumentation
  • Frans van Eemeren
  • Disputes can be solved by using formal
    argumentation that consists of attacks and
    defends of specified statements

31
Mass collaboration
  • Don Tapscott, Anthony Williams
  • A large group of unorganised people are able to
    produce complex artefacts, if the product is
    information or culture, the work can be chopped
    into bite-size pieces, and the pieces can be
    effectively synthesised.

32
Summary
  • The purpose of open assessment is to improve and
    make more efficient the use of scientific
    information
  • The basic principles are
  • Open participation at all phases of the
    assessment
  • Requirement of scientific method (openness to
    scientific critique) at all phases
  • Reusability of information from one assessment to
    another
  • Researchers are needed to test the ideas of open
    assessment
  • If successful, scientific practices may change
