- NCeSS e-Infrastructure for the Social Sciences meeting with Colleen Palmer about Finance
- Got a copy of a Grant Letter detailing the financial breakdown.
- I explained that there is a deal of overlap between MoSeS and this and that Paul and I had been working towards delivering D4.1.1 since January 2007. This work has not been officially charged to this project.
- Colleen has suggested splitting Paul and me 50-50 on this for a period over the next two years.
- I need to make sure Paul and Jie are happy with this.
- There is £1294 to be spent this year on equipment (PIGS and Laptop).

- Nodes 201,205-208,211,215 dead :-(
- Subsequent to the Meeting with Mark I have hit a major sticking point:
- I had been using CAS044 for NS-SEC not CASKS009a (as we assumed in the meeting) because I was to constrain (optimise) for HRPs in this instance only.
- The reasons for this was to match what the IPS code was doing as detialed in a previous meeting.
- The table layout of CAS044 was what I used for the original grouping and it seems like I got it right originally.
- Before I proceed, I have asked Mark to clarify if I am to optimise constrain on NS-SEC for all people, or for just HRPs.
- Perhaps the last few hours were not a complete waste of time as I am changing my code so as not to use the "Not Classified" group in the fitness function (optimisation). Not that it will make a big difference, but it's probably for the best.
- Meeting with Mark
- NS-SEC Social Economic Classification
- CASUV031 shows clearly the breakdown and how CASKS014a can be used for measuring fitness...
- It seems we can add an extra category into the breakdown we were using.
- I had not seen CASUV031 before.
- I came away from the meeting thinking I knew what to do, but as I write this I am confused (see above).

- Short Paper based on Sustaining an e-Infrastructure for Social Science accepted for Third International Conference on e-Social Science
- The abstract had three useful reviews suggesting work to be done for the final 5 page submission due 2007-08-31. I have cut recomendations from further useful critique:
- Reviewer 1 recomendation:
- Provide more detail on the various projects that have been funded and perhaps more importantly, how these have been selected to meet the needs of the social science community in the UK and internationally. Is there an overarching strategy by which the various jigsaw puzzle pieces represented by the funded projects will fit together to some coherent whole? (from Reviewer 1)
- Reviewer 2 recomendation:
-
Besides feasibility studies on the technical level of grid structures and related safety issues, the research interests are focussed on the
transfer of research outputs to services for social science, and to user-centred design issues. The final research focus centres upon the question
how to integrate the developed social sciences e-infrastructure into a wider infrastructural framework such as that offered by the UK NGS.
Although the question of user requirements and particular needs of social scientists are being described as important research objectives,
e.g. in contrast to the natural sciences which receive grid services by NGS already, I would recommend to centre more intensively on related questions,
e.g. on the motives and incentives for knowledge sharing and the socio-cultural contexts of the social science communities.
- Reviewer 3 recomendation:
-
A weakness of the paper is that some of the challenges identified, such as the need for consistent focus on user needs, while important -- are not novel insights (and are described at a generic level).
In the fuller paper (if accepted) it would be better to focus on aspects of the project that are unique to social science (as apart from general implementation of e-infrastructure for science).
In this regard, the section called "From research to science" is more interesting. It would be useful, though, to understand what criteria will be used to determine what tools and services will be retained and expanded from the first phase of the NCeSS programme.
- Be specific about where recommendations vis e-social science differ from broader e-science -- and how this might influence technology development and use.
- Liason with Gobe Hobona:
- University of Newcastle has just won some funding to develop an AJAX-based Client for OGC Web Services (COWS), together with Universität Rostock. It's envisioned that the client will cover all the major OWS specs.
- Looking forward to seeing the logo and further details for the COWS project.
- It would be good to plan a meeting of the NIEeS GridGIS Working Group again so we can catch up with activities and maybe plan some collaborative work. There are some related NIEeS Working Groups being set up and it would be good to find out where the overlap is etc...

- Meeting with Alice Milner
- Looked at various geomorphometrics for SRTM and other DEM data.
- Outlines the metric 1 geomorphometrics from Grids.
- Alice reckoned that the data would be of use and that her supervisors would be interested.
- Draping a colurful metrics over a DEM and getting a good angle shot is going to make a nice image for a poster...
- In the time period Alice is interested in the sea level is believed to have been higher.
- Identified a smaller study region to process for some results.
- I am planning to get round to this soon...
- We looked at Google Maps and Google Earth and the featured content:
- Discussed making Alices photographs and other data available as KML files.
- The terrain on the 3D fly through you can do with Google Earth is great!
- There are some interesting marks on the landscape that look hydrological or geological...
- It would be good to drape over some of the metrics on this.
- Pointed Alice to some Shapefile VMap0 data derived from the Digital Chart of the World.

- Meeting with René Jordan
- René is looking:
- at housing developments and the migrations of people into and out of areas being developed.
- to make contacts with Leeds City Council and Housing Agencies to find out what policies they have in terms of re-housing residents.
- to collaborate with Stuart Hodkinson.
- to focus on Leeds in the first instance.
- It would be useful to have all the housing data for the same regions:
- This was a brainstorm based on the idea of aggregating data to a common spatial frame.
- The houseprice data I provided has an address and full postcode.
- In theory this can be converted to point data for a flexible aggregation to any spatial frame.
- However, there is not a known address to coordinate lookup that we can easily employ.
- Ordnance Survey ADDRESS-POINT is the ideal dataset for this, but I don't think it is part of the CHEST agreement and available via Digimap.
- Once the houseprice data has coordinates attached, aggregation can be done in numerous ways:
- One can calculate the average increase in the cost of a particular type of house:
- The types are not detailed much and there is little to distinguish a large detached and a small detached for example.
- It would be good to know both volume and area of building, total area of property, number of rooms (of differnet types) etc
- Even with all this, it would be hard to distill it all in one metric for any area that represents a proxy for average houseprice inrease.
- An alternative is to use a look up from postcode to a higher geographyas per the All Fields Postcode Directory or the like...
- Easy Download: Postcode Directories
- Postcodes change over time, so there are many different look ups for the houseprice data although this is perhaps too extreme for what René is doing right now.
- Other data René has is Tenure and Housing Type and Special Workplace Statistics all for census regions.
- As a long term strategy it might be wise to use Middle Layer Super Output Area (MSOA) census regions as these are not to change for the 2011 Census.
- René seemed to think that my style of blogging is a good idea :-)
- It is going to be good working with René!

- The dreaded conversation about conversations about what is an agent!
- Alison hasn't got time to blog what is a blog conversation
- I would have argued that we don't have time not to blog, but I just stated it and left it at that!
- We talked about CASA and how we aspire to be more like them:
- CCG are poor cousins!
- We rate the CASA working paper series, blogs and web pages... More and higher quality than ours!
- They have an exciting number of PhD students and researchers.
- Chat with Dawn Parker in Alison Heppenstall's office
- Alison was mostly there...
- I asked Dawn about MASON and RePast development:
- Most of her reply is confidential.
- Is she involved in either or both?
- In RePast does she use Simphony or RePastJ or what?
- It has been suggested to me that MASON is well written compared with RePast and that I should use it for work on Agent Based Modelling of Daily Activity for my PhD.
- Am I right in thinking that GIS is loosely coupled in MASON whereas in RePast it had in the past it was embedded. (The loose coupling is favourable as there is a lot that goes on in developing GIS).
- Our understanding is that neither MASON or RePast are open developments
- I hope that at least one would move in this direction or I suspect that a new open development will evolve (perhaps based on one of these and perhaps a fresh start)...
- Dawn was not aware of High Level Architecture even after Georgios Theodoropoulos highlighted it at the Joint NSF-ESRC funded Agenda Setting Workshop on Agent Based Modeling of Complex Spatial Systems.
- My Web Content was very useful again in finding information...
- Even Alison is thinking of blogging now too!
- In the main, commercial organisations are producing better software than academic organisations.
- Academics need to work more collaboratively with commercial organisations and each other to develop models to support policy analysis and strategic planning and decision making.

- Meeting with Mark
- Based on some analysis by Mark, the MSOA GA results are looking good, but there are a couple of problems:
- The aggregated CAS003 data is missing 55-59 and 60-64 values!
- Is there an error in the aggregation?
- We are using different NSSEC aggregations:
- Wierdly Mark is classing "Lower prof/higher tech(trad):employees" with other higher occupations.
- Mark is also classing "Higher supervisory" with Intermediate occupations whereas I had grouped them with lower prof and managerial occupations.
- I have changed my code to match Mark's.
- Mark used Car Ownership and Provision of Care as non-constraint variables.
- The GA produced better fitting results for this.
- When I produce some of my graphed output I'll use these too...
- We considered more sophisticated handling of -9 (generally missing data or non-applicable variable) values:
- For health (good, farily good, not good) I am using a random equal probability assignment, which could instead be proportioned in respect of the total populations in each group.
- Andy to check errors and report to Mark and also check and provide a summaruy count of the number of households in each MSOA in the GA results.

- Asked Mark about going to meeting in Nottingham on Monday...
- MoSeS meeting with Mark on "Population Reconstruction Model"
- Mark had lost the thread of where we are up to, so I summarised:
- We were working on comparing the GA and IPS methods of Population Initialisation.
- Our plan was to change our code and produce the outputs based on the same inputs and constraining variables.
- We were both to configure for using MSOA level data.
- I was to include Ethnicity variables and drop many others that are being used to constrain in the current UK runs.
- I have configured and obtained some results for Leeds
- Mark has a copy.
- I need to analyse the results by producing new outputs that compare observed and optimised results.
- UK scale modelling
- I have been experiencing some problems with the reliability of the Beowulf.
- I am splitting up the problem and pushing each bit through.
- It would be good to make things both more robust and easier to show how far things have got.
- Making things more robust might be expensive, but that all depends on how much we are going to be using this code.
- Writing too many files is a problem, but having all results outputting to a single file is not ideal as parsing this to find out what areas have and have not returned results can get expensive in restarting a process.
- Actions
- Mark to do the IPS work so that we have results to compare on Tuesday.

- First step is to organise the graphing...

- A Spatial Microsimulation Model of the UK Population in 2030
- Belinda Wu, Mark Birkin, Phil Rees
- This paper will report on progress with the construction of a demographic forecasting
model for small geographical areas in the UK. The model focuses on the incorporation of
population dynamics through the representation of core processes including fertility,
mortality, ageing, migration, household formation and household dissolution. Sources of
data for the various model components are discussed and evaluated, and the outputs from
the model are compared with published third party sources. The forecasts will be
illustrated with examples from the city of Leeds, West Yorkshire.
- An important feature of the model is the extent to which the development in the
population is driven by interactions between individuals, and by the impact of the
environment of an individual or household on its behaviour. An example would be the
way in which an individual may search for a partner prior to leaving one household and
establishing another. Respect for these processes leads us to propose a hybrid approach
in which conventional microsimulation is combined with insights from agent-based
modelling.

- Interesting reading in newsletter:
- Alison Heppenstall has been awarded a £200,000 grant from the ESRC to develop agent-based models that are capable of incorporating and simulating human behaviour.
- Andy Evans, Linda See and Alison Heppenstall are all involved in a successfully funded NIEeS (National Institute for e-Environmental science) working group headed by former PhD student Hazel Parry (now based at CSL, York) entitled "AgriGrid: Application of e-Science to Agri-environmental Research". I wonder if Pete Edwards is involved... Find out more...
- Alison Heppenstall is involved in a second NIEeS Working Group with colleagues at Cambridge University entitled "Individuals and Environmental Change: eScience for sustainable systems".
- The purpose of both these working groups are to bring scholars together to discuss ideas and develop grants.
- Emailed Alison to request more information and she sent me two documents:
- Application form for NIEeS working group proposal: Individuals and Environmental Change: eScience for Sustainable Systems
- Application form for NIEeS working group proposal: AgriGrid: Application of e-Science to Agri-environmental Research
- Clearly the work in the NIEeS Grid GIS Working Group is relevant to both these new working groups.

- Lessons 1 and 2 are short and sweet. In lesson 2 there are some strange blue boxes that appear that are a little confusing and although Leeds is claimed to have been selected, Manchester is the name in the portlet box.
- Lesson 3 is slow and I am not sure if it is the defaults on the portlet that are annoying and resetting everything, but this needs to be reworked. I watched as different years were selected and different types of chart were chosen, but it was a little painful.
- It would be much better if our portlet interfaces were reworked so that scrolling up and down was unnecessary. I think we should have a separation of the user controls and the results viewing. Once the go button is pressed on each portlet results should appear or a progress bar should appear indicating when the results will appear. I am not sure if the results can be in a new child tab of the relevant tab and that this can then be activated and the results potentailly appended to a report. Anyway, these issues are for us to deal with.
