Dear Zoe, all
I clicked yes to allow research on my edits.
I think this is a bit of an advance on the previous research, which seemed
to rely on wiki pages, edits and discussion.
My impression of the UK community is that they tend not to use the wiki as
a source of guidance or rulings of any sort. This may be based on arrogance
as the originators of the project, but it seems to me that the wiki has a
rather German feel to it, as do some of the presets - it's best to
interpret Craft as being the German version rather than the English one for
example - rather more expansive and including a lot of mittelstand
manufacturing.
It's quite possible that the quarterly projects counteract earlier biases.
Because ther itch that got me into OSM in the first place was due to OS
licensing stopping me putting base maps under my mapping of poverty issues,
I've always been interested in mapping correlates of poverty. So, finding
that postboxes are much more common in social housing areas than in private
housing estates is interesting.
Mapping childcare is also interesting to me, but difficult. The difficulty
resides in the fact that childminders operating in their own home may not
advertise, and so there is no surveyable sigh of a childcare premise. As I
only use armchair sources to add value and check surveys, I'm not going to
rely on a list of childminders when the house contains to sign that the
list is right. The same applies to after school clubs. These are almost
never advertised, while nurseries and pre-schools are. Social care for
elderly people is usually advertised, but social care for children and
various other groups is not. The food hygiene data may contain listings for
these, which in some cases are suppressed (childrens homes, womens'
refuges) for obvious reasons, or in other cases are not verifiable by any
sign on the premises.
Mapping the FHRS data also enables pointing out some issues with other
research. There's been widely promoted research showing that fast food
outlets are more common in more deprived areas. Having mapped a selection
of less and more deprived areas, I have a fairly strong supposition that
the categorisation of food outlets differs systematically, with those in
deprived areas having a higher chance of FHRS categorisation of
Takeaway/sandwich shop, while in richer areas there is a greater chance of
categorisation as Restaurant/cafe/canteen. Where delivery is by Deliveroo
etc, the only practical difference is the existence of a sit-down option.

Dear OSM talk-gb subscriber
I am a Research Fellow in the Nottingham Geospatial Institute
at the University of Nottingham, interested in participation
biases in geospatial crowdsourced projects such as OSM and other
Volunteered Geographical Information (VGI) projects. My current
research project is concerned with the way in which
participation biases in OSM may potentially affect the usability
of the data that is collected and subsequently what is available
to location based service providers which use OSM as their
primary geospatial database.
The project is motivated by recent research that has found a
strong male bias in OSM participation. This has led to
assertions that various geospatial knowledge could be under
represented or poorly recorded on the map. However, the actual
consequences of this bias remain little explored or reported. By
collecting information about contributors to OSM, which can then
be analyzed along with their editing patterns, the impacts of
this bias might begin to be measured and therefore better
understood. I have therefore published an online survey designed
to collect information directly from OSM editors and I would
like to invite as many of you as possible to participate. The
survey is anonymous and takes a couple of minutes to complete.
If you are an OSM contributor and are interested in or would
like to participate in the study, please click on the link
below, which will take you to the Bristol Online Survey website
where you will find more information and an opportunity to
participate in the survey. As a small incentive, at the close of
the survey in a few weeks’ time, 60 respondents will be drawn at
random to receive a £15 Amazon voucher.

Please do think about participating. It is hoped that knowledge
about the way participation biases impact on crowdsourced maps
will enable new strategies to be developed to address any
resulting voids in the geospatial information provided by
amateur mappers. In turn this could strengthen the role played
by platforms such as OSM in urban planning and sustainability
and raise the profile of the important mapping work that you all
do.
In the meantime, if you would like to know more about me, my
research activities or the project, please visit my University
webpage (link below) and do not hesitate to get in touch
directly or via the OSM messaging service.
