Mental Mapping Architectural Experience - by Donna Wheatley
------
Guest Post by Donna Wheatley for single-blogs
------
One of the features of the mapping technique developed in the PhD is that individual and consensus conceptions of designed environments can be generated. This can then be used to compare the mental maps that the architect has towards the environment they designed with that of the user group. As a designer I am familiar with the expectation to incorporate specific abstract values into architectural designs, but it is difficult to know if these efforts are successful or in how far this has been achieved in previous cases. In response, I undertook this study at half a dozen new corporate headquarters in UK, Germany, China and Australia, where attempts have been made to attract and retain employees by communicating particular values.

The data for the maps is derived from in-depth interviews with users, architects and clients using metaphor elicitation. The interview transcripts are coded by extracting identifying keywords and grouping them in pairs. These pairs form semantic networks which are read as the mental maps.
Determining what thematic clusters or topics emerge (called ‘metatopics’) from the networks is a primary aim. The networks usually contain 4-7 metatopics. A range of network analysis algorithms, calculating measures such as centrality and proportional strength of ties are applied to identify important constructs and help identify metatopics (I will now apply additional analysis procedures on advice from CASA researchers – thanks!!). These metatopics can also themselves be ranked and compared through network analysis indicators.
Through these tools, new observations on the structure of collective mental representations of built environments are gathered.

I visited CASA at the beginning of 2010 to discuss the analysis and interpretation of mental maps of architecture in my PhD at The University of Sydney. I gave a presentation called ‘Mental mapping architectural experience with network analysis’ at one of the weekly CASA seminars which can be found on their website. These maps are visualised using social network analysis software Pajek.

The Temporal Narrative of Space
I will be presenting a paper with he title ‘UrbanDiary - The Temporal Narrative of Space or the Construction of the Collective and its Visualisation’. The main focus will be on the last part of the manufactured title construction, the construction of a collective and visualisation aspects of temporal data.
A brief summary will form the introduction to enable everyone to understand the extent of the investigation as well as to grasp what field work has so far been undertaken. This set the background for the explanations and ultimately the discussion to follow. The focus of the explanatory part is held on the experience and perception of space. The aim is to build up, on one hand the methods and ways of investigation and mapping , as well as on the other hand introduce the concept of the narrative. Along the story of individual experience, the narrative of the space and ultimately the city is redrawn. It is not so much the mark on the city, but the mark the city leaves on the individual that interests. It is hoped that this also clarifies the position. However, the aspect of the body and is left out of this discussion. This is mainly to not confuse the direction of the discussion.
The Discussion part is dived in to two section, the possibility of a collective construction and the visualisation of the findings. Earlier is illustrated with track records shown on a city level including and connecting to the immediate urban morphology, followed by the UD London map. The new twitter weekend map is then used to illustrate other sources of data that could be interpreted as collective. However this is mainly thought as a starting point for the discussion around the construction of a collective and its value compared to the individual data.
With a activity graph based on time and amount of activity, the transition to the topic of the visualisation is introduced. Also the time-space aquarium will be up for debate and an animated UD London map.

Tweet-O-Meter - the Tweeting Habit of Cities
So what are people talking talking about in 2010 in these cities?
Currently in beta mode the TweetOMeter updates every 10 seconds displaying the city with the highest number of Tweets, the logged 24 hour period will be announced next week. Once logged we will be able to make city maps showing the Tweet activity over time and space, the system will be launched as part of a free data collection service via NeISS in the next couple of months.
Tweet-o-Meter is designed to mine data for later analysis relating to furthering our understanding of social and temporal dynamics for e-Social Science within the Twitter demographic. It is under development at CASA, University College London as part of a wider survey tool as part of the NeISS project in association with single-blogs and Digital Urban, code by Steven Gray.
One of the main interests will be the temporal user pattern contained in the data. Twitter offers a great platform to look into details of the urbanNarrative quite literally. The aim will be to map the development of the narrative in the spatial context and integrating it with the social network.
Click on the image below to view NewYork, London, Paris, Munich via TweetOMeter and if your in one of those cities and want to take part, simply make sure you have geolocation turned on in your Twitter preferences.

Twitter Never Sleeps - TimeLapse Tutorial
It is busy all the way round the weekend.
Twittermaps the location of the outgoing tweets according to the geoLocation. However there is a bit of confusion at the moment what this actually is. The information was only recently introduced by twitter and is not used very much by users and developers. So there i a workaround in place. twitter codes via Google the location saved in the profile of the twitter user and adds this as a geoLocation. Similar the actual geoLocation field also updates the location of the profile, so a lot of confusion around this at the moment.
Because of this most of the tweets in this visualisation come from central London, Westminster, around the House of Parliament. This is because this is Google’s geoLocation for ‘London’. The blue lines that start cluttering up the screen are @tweets, directed at another user.
If you have been tweeting over the weekend it is very likely that you find the message in the clip some where, check the clock on the top right corner. If you happen to spot your tweet in the clip, drop me a line.

The clip is produced via a screen grab tool, that would capture the map about three times a second, e.g. 3fps. Tools for this are available online for example SnapzPro or screenFlow. More software for the mac can be found at pure-mac. This is then either put together, if a real timeLapse, or processed in the software if a video. For clips a low frame rate is advisable, most likely you don’t want to watch the whole weekend in real time. You process the raw material, in my case with 3fps it ended up being some 20 GB, to fit a clip with 25 or 30 fps. The processing brings it down to some 9 GB, in my example. To speed it up you need some video processing software. Take iMovie or Premiere, I was using QuickTime Pro, I love the tool. There is no simpler way to speed up the clip. Simply copy all, and past and fit to a five minute clip.
As a nice feature to visualise the time passing I have placed a desktop clock in the frame. This gives a good indication of time and speed.
We have currently the twitter virus her at CASA. The content mining started with the CASA version of the ukSnow map, the iPhone signal strength map and we are developing some more tools - coming soon.
Transport - the Machine is on
Beautiful how the the dots buzz around. The back and forward pattern is not as obvious as expected, for this the D.C. area is simply too busy. The overall pattern of an ebb between two and four in the morning is something one would expect, however it seems surprisingly short.

REVIEW:Bollywood Actor Salman's VEER
Set in the times when the British were colonising India, Veer is a tale of bravery, treachery and love rolled into one. As the British enslave India with their shrewd 'Divide and Rule' policy, kings and nawabs fall to their guile and entrust their kingdom to them, one of them being Jackie Shroff, the Raja of Madhavgarh. He cheats the Pindaris, a fighter tribe from Rajputana, to please the British and loses his right hand to Prithvi Singh (Mithun Chakraborty).
Prithvi, one of the proud heads of the Pindaris, swears to return and kill every white man and the Raja to avenge the deception that cost his tribe, their land and their reputation. The vile Raja of Madhavpur too harbours a similar intention behind his cool demeanour. But as fate would have it, little did he realise that one day his daughter Jashodhara (Zarine Khan) would fall in love with the bravest of them all, Veer.
Now Veer not only takes on the British rulers, he also has to fight the cunning Raja of Madhavgarh. But then he has fallen head-over-heels in love Jasho and has killed her brother (Puru Raj Kumar) too. Will he succeed or won't he is for you to figure out.
Salman seemed to be back in form. He has lost more weight this time and looked better than in Wanted. It felt good to see him dancing gracefully and emoting right at the same time, maybe because Salman himself has invested a lot in terms of story as well.
The film has good music with a few hummable tracks.
But the discussion would be incomplete if we don't talk about Sallu's action sequences and his dialogues. As in Wanted, here too he has a few punch lines kept aside for his fans. Sample this: Ek bar leta hoon toh paanch ser gosht le ke hi chhodta hoon. If this was not all he goes on to prove it by actually killing a rebel Pindari with his bare hands by scooping out his flesh. And guess what he comes up with? 'Tol lena, paanch ser se zyada hi hoga." Woof!!

Book - Otto Neurath - The World Simplified
In a stunning publication Nai Publishers have dedicated a book to one of the founders of our contemporary understanding of visualisation. Don't worry if you haven't known him before very few actually have. His name is Otto Neurath. The book with the title 'Otto Neurath - The Language of the Global Polis' by Nader Vossoughain tells the story of this Austrian sociologist who did not fear any topic or occupation to follow his interest. Neurath is an incredible vital and versatile scholar, practitioner, politician, theoretician, developer or craftsman. What we maybe don't know is his work, but remarkably it feels somewhat familiar, as if we'd known it.
Image by Otto Neurath, taken form gis and science where you can find a collection of Neurath's illustrations.
The publication is in the tradition of Nai publishers a truly nice designed piece and it has this surprising twist to it, it is a hardcover but in the form of a paperback, I love it.
The book redraws Neurath's life along his work and engagements. It puts a special focus on his collaborations with well known figures of his time, such as Le Corbusier or Corneis Van Eesteren. The later's work was also currently published by Nai Publishers in the book 'The Functional City' also reviewed on single-blogs (1, 2). The author has chosen to structure the book along three major topics under which Neurath's work can be organised, community, democracy and globalism. It gives a good sense of the broadness of Neurath's work and involvement. However it can be confusing as this structure is not chronological, but the content is still based on his life. So duplication and repetition can no be avoided. Nevertheless this also has an upside and can for the observant reader lead to some hidden 'Pulp Fiction' moments, were the same situation is seen from different vantage points.

Image taken from the book 'Otto Neurath - The Language of the Global Polis' (p 64) / "Neurath felt that cut-outs allowed the masses to feel as though they were participating in the production of knowledge, which was central to his philosophy of reform in general"
In 2008 there was also an exhibition at Stroom den Haag on Otto Neurath curated by Nader Vossoughain. A lot of the content i still accessible on line, including a video interview with the curator.
The modern day version of Neurath's icons or isotyes can be for example found at AIGA, the professional association for design, at the Isotype Institute or seen in use for a chart visualising the war in Iraq by the NYTimes.
As seen, still today, some will claim even more so, the visualisation is the very big topic. Together with the computer and finally with the internet increasingly unbelievable amounts on data a created, recreated and shared. Large collections only now with the contemporary technology become accessible. Recently the public claimed successfully to free data sources and open them up for public access, e.g. data in the UK and London specifically -London data store. Not that the general public can handle or understand all this information but currently they have the power to put on enough pressure. But globally visualisation is the hot topic. In all areas but also specifically in politics a traditional field of facts argumentation.

Life Cycle - the Idea of the Nest
Image by Donna Schwartz from the series Nest / Before.
The course of the life is what we make of it and it takes many twists and bends. It is for the individual in the present a somehow difficult unit to grasp. The personal finiteness is a constant companion and part of the identity, but not in absolute value. The focus is on shorter timespans and immediate tasks. It is however for the collective an important unit. Much of the stability of society, a community even a family rests on the unit of the life cycle. Generations and the presence of the past bring with them the security and identity shaped through the collective memory.
Hagerstrand focused on this larger unit in his 'Survival and Arena' (1978) as discussed HERE. His visualisations show how the farm, as such the place, was maintained through the continuos 'life lines' of the individuals 'passing by', but it was less the distinct individual than the overall character of the sequence that defined the place.
However for individuals different aspects or events of the life have a 'place' changing character and one of them is definitely the moment the 'individual' transforms into a 'collective'. Of course this is culture based and depending on the individuals character and circumstances, however a certain trend can maybe be described. The concept of the family plays an important role her, but the 'arrival' of the child marks an uncertain moment. A moment that will be prepared, but how. Modelled on personal experience, from memory and peer information a tiny little world is constructed, a world for an new individual, a new generation - the nest.

Steam Water Ice - Seasonal Cycles Wrapped Up
It is not as if there are better seasons or worse, but strong character associations exist as part of the culture and for cultures worldwide according to the local seasonal conditions.
Image taken from serc.carleton.edu / On a 500 million year scale, we see the Great Ice Ages!
The UK, just had one of the snowiest winters for over thirty years. There was some covering on this HERE. A lot of people on the street start now explaining these events with the global warming. It has sunken in, that something is happening with our planet.
However cold and warm periods where always part of the overall shift beyond the seasons, on the scale of thousands of years. This time however the increase in temperature is different.
The seasonal build up and melting away of ice in the arctic and mountain regions is part of the seasonal phenomena. This way the ice works as a fresh water storage for the planet. If there is now more ice melting away than is produced during the colder month less fresh water is available during the hotter month.
Image taken from Eiger International / IceProtector Optiforce in action, location unknown.
Several projects are now testing methods to keep the ice cool during the summer. In Switzerland special ice blankets are used to cover the ice and snow to protect it from the summer sun. However you can probably not attest them of saving the planet, but more their ski slopes, jumps and half pipes for the next season of winter tourists. Nevertheless the same technique has now been used in trials for larger scale test to tackle global warming phenomena. A produce of the sheet material is the Landolt Group based in central Switzerland.
This is how it works: “A lightweight dual-layer composite, its top layer consists of polyester to reflect ultraviolet light while the bottom, composed of polypropylene, is a polymer that is often used to block heat. Its purpose is to prevent a glacier’s top snow layer and permanent ice base from melting in the summer. At a cost of $12 million per square mile, the material has already proved successful in a small pilot in which its use on the Gurschen glacier resulted in 80% less melt than surrounding snow and ice two years in a row.” (as explained on threehugger)
It looks a bit funny, but has this poetic element to it that we were introduced to by Christo and Jeanne-Claude with their wrappings of natural and artificial features. At first when I saw the images I thought it is a joke or another Christo copying project, but it appears to be serious. Everyone seems to know about this - why hasn’t anyone told me this before?

The blankets are now tested around the globe, from Europe to Aspen. Here a clip that introduces the snowtorium in Jackson WY.
Discovery Channel documents a project to use the ice blankets in Greenland to stop the ice melting away as a result of the global warming. This is for a change a real hands on solution. The climate summit in Denmark is only a few weeks in the past but the debate about the problem of global warming is already dried out. Would be nice to see more of these hands on proposals and less talking about who is responsible.

The Speed of Things - BBC Life Series
Being trapped in such a short term time experience mode, it becomes really different to relate to longer term time phenomenon. Already the structure of the day is difficult to grasp. It will get dark at some point but will realise when we get there. Time frames beyond this are out of reach without proper assimilation. Take the tide for example. It changes twice a day and still it is almost impossible to relate to as a ‘fast’ living citizen. This phenomenon featured earlier in posts, see HERE.
Other timescales moving at a different pace are way beyond and all we see are key frames. Take the plant on your windowsill. Does it look the same everyday? I bet it does, to you. At least I only realise something happened when it flowers. I most likely wont see the tiny first bud, maybe realise when their quit big and the next time the flower has opened. But something is happening in between, the plant moves and changes, grows and moves.
TimeLapse can be a brilliant tool to visualise this kind of change. Where better to look than at the BBC. In their Live Series they produced these astonishing visualisations capturing this change at a different pace. In an only 60 second shot they compress the growth of a range of flowers in a stretch of wood over a whole season. It took them a year to to produce this short clip. THe result is astonishing and most likely the most complex scene in natural filming.
The rest of the parts are accessible here: Part two, Part three, Part four, Part five
This is documentation on how it was produced.
