'''Joint method development period''' was an idea from the second annual meeting of Intarese. The idea in short is to get the key method developers from different institutes in one place for a long enough period to be able to produce and finish something during that time.

==SP1 meeting notes==


==Comments and discussion from the SP1 leaders from London meeting 20.3. ==
The SP1 meeting 20.3. notes have been moved to: [[SP1 Integrated assessment methodology]]
 
===Introduction (Erik)===
 
Comments from David
*Where do policy options come from?
*Some WPs are looking at positive effects as well. These might not fall on source-effect causal chain.
*Two ways to see what we'll do.
**Everything is forced into full chain approach
**If the case does not match the approach, do something else, but there is a need for guidance what to do then.
**:-->Matti: Everything is layered, and these layers may be express conflicting conclusions for a certain policy.
**::David: I don't see this layering as a major problem; each WP will start from some layer that is natural to them.
**:Jouni: All diagrams should be based on causal connections, mind maps etc. should not be used. This is the basic guidance.
**:Anne: In the workshop we started from the basic diagram but then squeezed it a bit to fit the case. We need a tool for doing the diagrams.
 
*Marco: It's funny to hear that some think full chain approach (FCA) is a narrow thing. One thing is to use variables with measurable quantities. I don't see a problem in including positive AND negative effects.
 
 
*David: Some WPs are doing rigid things, some more flexible. Does this group have guidance on how rigid they should be?
*:Matti: FCA should be used whenever possible.
 
 
*Jouni: We should look at SP3 diagrams in practice and not talk about this in theory.
*David: Diagrams have been there for 6 months
*Gerard: SP3 is waiting for comments, and nobody gives it. There is a lack of collaboration.
*Erik: People already had their mindmaps when the projects started, and they are unwilling to give that up.
*Irene: It's confusing. Some say you must start from certain ends, I think you can start from either end of FCA and go up or down.
*Erik: We selected 7 cases bases on stressors, not health effects.
*David: Yes, and many in SP3 don't like that, because they want to focus on health outcome instead of a stressor.
*David: SP3 wants to play the game, but they have not been able to get advice and ask for further help although they know they need it.
 
 
*Erik:Do we need FAQs and also less frequently asked questions?
*David: Most of the problems are in the overall concepts
*Erik: This is to blame me, because the framework is missing.
*Martin: Are the issues captured in the guidance documents?
*Marco: Workshop emailings: many had in their heads ideas about scoping. What questions can we really tackle with this approach? Housing/energy effiiciency: does it work? We should realise that the approach can be good even if it does not work with a specific case.
 
*Anne: USTUTT is working on glossary about the major issues, including "integrated".
*David: Let's make a statement: These issues will be closed by the training workshop. We need guidelines.
*Erik: I'm afraid that we will give too general guidance, which does not help.
*Matti: We're providing guidance and models in WP1.2.
*David: SP3 is already half way doing their job. They'll hate it to be guided afterwards.
*Gerard: We need documents like Uncertainty document.
*David: I agree. There are some general questions that need initial solution now.
*Erik: We need to get contact to SP3 leaders before the training workshop.
*Gerard: I disagree, we need good documents and not meetings.
*Erik: HIA included benefits, RA only risks. Intarese contains both but does not force HIA.
 
 
*Erik: There is an issue on who will define the policy scenarios in a case.
*David: There are examples of cases when this has been done well or badly. Key readings: Chris Murray (this is in internet [or intranet?]).
 
 
*David: We are going to SRA-E with speakers from SP1 and SP3. Send basic information.
 
===Wiki environment and workshop outcomes===
 
[[media:Feedback from Kuopio workshop.ppt]]
 
Jouni presented the results of the workshop and suggested the use of Mediawiki. This was strongly opposed and considered as an irrelevant issue in this meeting. The focus should be on the contents instead.
 
 
*Matti: Before the process, two steps:
**Political framing about what is the basic question (experts participate).
**Scientific framing about the key issues within the boundaries. This changes only when someone comes up with strong arguments to expand.
*David: I agree but there must be open participation also.
*Matti: I agree, I just didn't mention it.
*Martin: May not happen in this order: experts write a draft, stakeholders participate, then fixed by politicians.
*Erik: Science can help in framing.
 
 
*Erik: Framework has been circulated between David, Erik, Irene, Anne. (How-to-do type paper). This will circulate more widely soon.
*David: Causal graphs from SP3 will be updated soon (next week).
 
=== Key issues in WP1.X===
 
 
'''3 Key things in WP1.4'''
 
*Connections to the framework; finishing the workshop report
*Finishing methodology reports to Wiki
**Monte Carlo guidance
*Method development
**Stakeholder involvement
**QALY/DALY, monetarisation
**Templates vs. specific
*--> David: This should be elaborated with SP3
**Stakeholders: we could have a breakdown session at the training workshop.
**Erik: Should we prioritise these to get something in the training workshop.
 
 
*David: there is a heated debate about how you can combine tox data (in general).
 
 
Marco: High-resolution data and its use?
*Matti: There are several uses.
*Erik: Why couldn't we use high-resolution data with general dose-responses. It should be possible.
 
 
*Anne: It is a general issue of multiple data/no data/not exactly applicable data (or models)
*--> this goes to 1.3 to think about
 
 
Valuation and weighing
*Martin: We need to standardise the process of deriving values, not the standards for weights.
*Erik: Yes, but there is some previous knowledge about weights and we can use that.
*David: There have been lots of studies in valuation studies. SP3 may want to just take a value from a shelf.
 
 
'''Marco: 3 key issues in WP1.5'''
*Uncertainty
**Tools for practical implementation (is this MNP?)
**Training session for autumn (probably October)
*Mixture exposure, vulnerable groups, ethical value systems, equity
**We have had problems with the level of generality: these have not been practical enough.
**Not far enough to provide informative output in the training workshop
*Economic valuation...
*-->David: We must say something on these issues in ithe workshop
*Anne: This comes back to issue what to do when the data/model does not fit.
*Gerard: Mixture issue is included in WP1.3 protocol - good place for WP-communication.
*Matti: We could have a walkthrough of these issues in May with one of the SP3 cases.
*David: MNP tool was not welcomed in Copenhagen meeting - lot of filling in without much of useful output.
 
===Training workshop===
 
*Marco: Previously they have been general presentations. Do we want to have some hands-on issues
*Erik: Yes.
*Anne: Maybe some plenaries and enough time on a few case studies.
 
 
Stakeholders:
*On the first pass, we should test at least on some cases this.
*Martin: van den Sluijs has a manuscript on stakeholder involvement. We should get him involved.
 
 
*Erik: Practical interaction, not lecturing
*For SP3 mainly: leaders and deputies, but also others
**SP3 should be able to give presentations
*22.-23.5.2007 CEFIC, Brussels starts early (arrive previous day)
*David: How to make SP1 to learn from SP3?
*Anne: Send beforehand list of possible trainings, and people can vote
*Martin: Make 3 slides per case but ask: what are the uncertainties, what are the key issues,...
*Gerard: We need an active workshop, but we should work in one group instead of split up.
*Erik: SP3 must be able to prepare in advance. Not go through every step.
*David: I can extract comments form SP3 within the next month.
*Erik: Stakeholder involvement report came out a few months ago from UK
*David: CDC has a 200-page document + software
*Erik: Airport case study could be used + SP3 cases
*Anne: Some WPs could test some methods beforehand
*David: It's not their job to do it now but during the next 2 a.

Joint method development period was an idea from the second annual meeting of Intarese. The idea in short was to get the key method developers from different institutes in one place for a long enough period to be able to produce and finish something during that time. The joint method developement period was organized by KTL and targeted mainly to SP1 & SP4 people, although participation was open to anyone interested. The joint method development workshop was held in Kuopio 12.3.-23.3.2007

This page contains information on the joint method development period and a brief description of the means and tools that are currently being used in applying the pyrkilo method in environmental health risk assessments in KTL. Please feel free to make major edits when necessary.

SP1 meeting notes

The SP1 meeting 20.3. notes have been moved to: SP1 Integrated assessment methodology

Method development period

The participating institutes from Intarese (and their representatives) were RIVM (Anne Knol), USTUTT (Alex Kuhn), NILU (Sjur Björndalsaeter), UU (Hanna Boogaard), IC (Clive Sabel) and KTL (Risk analysis group WP1.4 + air hygiene lab WP1.2). In addition we had Mari Vanhatalo from University of Helsinki / EVAHER project and Patrycja Jesionek from TU Delft / Beneris project visiting the workshop for a few days during the first week.

The aims of the workshop were

  • to familiarise everyone to the tools that are being used and developed for risk assessment in the participating institutes
  • to identify possible overlaps, gaps, and interface mismatchs, and try to find a reasonable solutions to these
  • to work together on a specific case study in practice with the existing tools
  • to gain practical experience on the tools and methods and identify development needs
  • to write a report about what we learnt for internal use in Intarese (or even for external use?)


The above picture was made before the workshop as an attempt to represent an outline of the available methods and tools to be used in the workshop case study (and in applying the Intarese method). This idea developed further during the workshop and the results can be seen in the tables at Tools needed in Intarese toolbox page.

The structure of the workshop

We started working on a practical case attempting to make an integrated risk assessment using the methods and tools we have available or are developing within Intarese. The case study topic was chosen to be Schiphol airport (air pollution+noise; air traffic+surface traffic).

The workshop participants could be roughly grouped e.g. as follows (duration of stay in Kuopio in brackets):

  • core workshop team: Jouni, Mikko, Anne (12.3.-19.3.), Alex (16.3.-23.3.), Hanna (12.3.-19.3.), Sjur (12.3.-15.3.), Clive (14.3. evening - 19.3. morning), Mari (15.3.-16.3.), Patrycja (15.3.-19.3.)
  • KTL team: Marko, Olli, Anna, Virpi, Eva, Miranda, Markku, Juha V (system support)
  • local leaders: Matti, Juha P
  • remote leaders: David, Erik, Marco, Gerard, Rainer, Aasmund, ...

The core team was working full-time on the case study during their participation within the workshop period. KTL team also strongly took part in making the case study assessment as well as participated in meetings and other discussions, but naturally were also involved with other issues beside the workshop. The local leaders took part in some of the meetings as were available from other duties and also held some other Intarese related discussions and meetings with the participants during the workshop.

The remote leaders were incorporated in the process by preliminary e-mail discussions on the case topic, a teleconference meeting on the second day of the workshop (which unfortunately failed due to technical reasons), access to follow-up on the Intarese-wiki, an intermediate report delivered to the SP1 meeting (+ feedback on it) and final reporting on the workshop. The lessons learned and other outputs of the workshop will be also presented in the SP4 meeting coming up in mid-April. Participation to daily morning meetings via phone was also possible and was made use of a few times.

      • this serves the purposes of both guidance and feedback to/from SP1 & SP3
  • We should develop the idea of producing ascientific article about the workshop and its outputs
    • e.g. the process of creating the Intarese method (Clive's proposal)
    • this should be done following the Intarese dissemination strategy

Issues to be resolved

What are the methods that will be recommended for case studies?

What are the tools and software that will be recommended for case studies?

Which methods and tools will be included as parts of the Intarese general method?

Will the Intarese general method and its products be totally open access (General Public Licence GPL)?

What is the most important output for SP 4 and the toolbox?

  • provide a workspace
  • maybe test out methods (e.g. for issue framing) in a draft environment while the design phase is still ongoing
  • We have collected all the necessary parts of an assessment and the corresponding methods and tools. This is a good basis for the needed functionality of the toolbox.

Pyrkilo interface

In this section, we describe the different tools that we have been developing in KTL and within ERAC (Environmental Risk Assessment Center, Kuopio. ERAC is a joint effort of KTL, University of Kuopio, and National Geological Survey of Finland). We have NOT added other programs and tools to this platform, such as the demonstrator of the current toolbox, or the uncertainty program by MNP. This is not because we wouldn't think they aren't important. They are. But we thought it is better to first show what we have and what we don't have in our institute, and only then add other things to the platform.

Overview

The purpose of the platform is to offer all functionalities that are needed to perform an and publish its results. This includes issue framing, drafting the model and variables, collecting data, estimating the values and distributions for the variables, evaluating stakeholder preferences, computing the models, storing the results, and displaying the results to the endusers. Several people and groups of people would use this platform. Depending on his/her role, a person can participate in several different phases of the risk assessment process and contribute to several different ways by offering understanding, opinions, and information. There are many user interfaces to deal with the many tasks that occur during a risk assessment process. The technical details are destribed below in more detail. The methodological issues are described in a manuscript about pyrkilo method, and a draft manuscript about efficiency issues related to the method.

Programs used in the platform

The platform consists of several programs.

MediaWiki

MediaWiki is the central program in the platform. It is the same program that is used to run Wikipedia, the open encyclopedia. It is basically a content management system with an internet-based, user-friendly interface that allows a number of people to work on a set of documents simultaneously. Its major properties are

  • a strict version control
  • a simple coding and formatting system
  • user identification
  • contributions released immediately to everyone to read
  • possibility to attach discussions of the content. Each page has a discussion page for this purpose.
  • good working environment for text and figures (also tables, although a bit more complicated)
  • good categorisation and search tools for pages
  • possibility to use templates (a block of content that appears the same way on several pages)


Mediawiki is not especially good at (although it can handle these)

  • copy-pasting contents back and forth from one program to another (formatting problems)
  • storing ready-made documents (not a file management system)

Risk-assessment-related functionalities in MediaWiki:

  • Main namespace is an area that contains article-like descriptions of risk-related issues, such as risk assessments, method descriptions etc.
  • Variable namespace contains more structured contributions in the form of. This namespace
    • describes variables and their attributes
    • describes causal links between variables
    • Describes the discussions related to the content of a variable on its Talk (or discussion) page.
    • describes the value judgements related to outcomes or other variables.
    • describes smaller pieces of data (and gives links to larger pieces) and describes how the data was used to derive the estimate of a variable.
    • describes rank correlations between variables (possibly using vine copula method).
    • describes set-item relationships between items. This means that a variable may inherit properties from a more general variable of the same kind.
    • describes other non-causal relationships between variables.
  • Model namespace contains Analytica and other model files. There can be translated into variables in the Variable namespace or updated based on existing variables.

Analytica

See Monte Carlo simulation.

Result distribution database

Result distribution database is an idea of an SQL database for result distributions of the variables. The main idea is that the variables and their distributions are program-independent in this environment. If their precalculated result distributions are stored in a database, the risk models can be analysed based on these results independent on which program was used to produce the results. In addition, if the model runs are done in a coherent way, these distributions form a large joint distribution that can be used to conditionalising, backward inference, and optimising, which are usually difficult tasks.

The main properties are

  • a large SQL database where each variable forms a table
  • each table has a fixed number of rows, which equals to the number of simulations used to calculate the model (in the pilot version, this could be in the order of 5000, but in the real database, it should be in the order of 1,000,000 to 10,000,000.
  • tables indexed by predefined fractiles to speed up the performance


Major problems

  • needs constant updating and simulation (requirements for the hardware)
  • When the structure has been fixed, all models must have the same number of simulations irrespective of model size.

Alternative programs could be

  • Netica, a commercial program for handling joint distributions based on sample files.

Other possible programs

These programs do not exist in KTL, and there is not (yet) active development going on related to these. However, they could be potentiallly useful programs to attach to the platform.

File management system could assist the risk assessment by providing a centralised database of original data that could be used in the modelling.

Value evaluator could be a web-based questionnaire where stakeholders could rank different outcomes or events in the order of their personal preference. These could then be synthesised and used in the valuation process of risk assessment outcomes.

Expert elicitator could be a web-based questionnaire where experts could give their best estimates on various variables. The answers could be synthesised based on expert-specific weights that would be determined based on their previous performance in this task. There are existing methods to do this using extensive interviews, but it has never been tried over internet.


Interfaces needed to get the platform running

Mediawiki and the user interface exists already, as it is a major part of the Mediawiki program. It is continuously developed by a large Mediawiki community. KTL has a specialised ICT person to update and develop Mediawiki used in pyrkilo risk assessments. We have several projects that constantly utilise this interface, and experience is increasing rapidly.

Ana-Wiki interface is about 1) translating Analytica model files into Mediawiki pages as variables, and 2) updating Analytica model files based on the updated contents in Mediawiki variable pages. This development is ongoing in the Beneris project and these interface tools should be available during spring 2007. We are currently testing a pilot version of Ana-Wiki converter.

Database interface is for converting Analytica (or other simulation program, such as R) results into the database. Analytica has functionalities for input/output from/to SQL databases, so this should not be a huge task. However, we do not have practical experience on this. We are actively testing this functionality, and we should have more experience before February 2007.

Result interface is for showing results from the database to the endusers. Although this is a critical thing and should be developed carefully, it can be postponed to a later stage when the other parts are running. However, some kind of pilot interface should be developed rather early so that researchers in the project can test the database and its functionalities.

Data interface, Elicitation interface, and Evaluation interface are only needed if these tools are developed further. These are not crucial thing at the moment.
