datamining maps visual graphic

  • Really nice. Be great to see the two combined – heatmaps and topography or atleast some kind of colour banding added to the topography. That would open up all kinds of possibilities – you could slice horizontally along the bands and create layers of different ranges. In fact mixing colour and topography would also give you a way of showing two sets of data concurrently – topography for prostitution and some kind of colour banding for wealth for example.
  • Makes the numbers come alive. G
  • Brilliant work! Can you cross this data with the physical typography? I’ve always been curious if safer neighborhoods are uphill.
  • ...5 more annotations...
  • It would be interesting to pull the data in from previous decades and see how the elevation has changed in different areas.
  • @adrian – it’s just raw totals, grouped geographically. These aren’t scientific by any means, I basically took the underlying pattern and extruded it out and smoothed it a bit to make it look “pretty”. But basically each image is the aggregate numbers for a single year of crime data.
  • @richard – yes, there is some smoothing in effect, which means that the ridge along Shotwell St (for the prostitution map) is indeed a bit smoothed between peaks. That’s not to say that there are only two peaks at Shotwell and 19th and Shotwell and 17th. There are incidents in between as well, but the big peaks at those major intersections does mean that the ridge between them appears higher than the actual incidents along those blocks support. A lot of people have commented on the usefulness of maps like these. I want to stress once again: this was done as an art project much more than a useful visualization. My goal was not to provide useful information that one could act on.
  • “one trick pony. these maps add nothing of value to a standard color plot.” I disagree: allowing for a third dimension of elevation makes the reality of concentration clearer – and half the point of crime mapping is to measure concentration, not simply “intensity.”
  • Great idea and nice work on the graphics, but there are at least three improvements you should make to reveal *true* patterns. Forgive me if you already did these. 1) Availability bias – normalize for population density (i.e. per capita activity) 2) Sampling bias – normalize for the number of cops on the beat (geographic and crime type) 2) Frame bias – break it up by daytime and night time

  • Half of U.S. adults use social media.
  • Combined
  • n the 18-34 year-old demographic
  • ...8 more annotations...
  • t's worth noting that in this particular study "social media" includes text messaging. Combined with blogging and social networking, these three technologies are used by 50% of U.S. adults for communication purposes.
  • 85% of rely on one of the three platforms to stay in touch with others.
  • demographic
  • Side Note: Personally, I find the terminology "the great unwashed (masses)" a little demeaning. The fact is that those at the lower end of the technology-use spectrum don't use things like text messaging and the internet as much because they are usually economically disadvantaged - an unfortunate condition that has numerous causes including everything from poor educational resources to lack of job opportunities in their geographic region. Lumping this lower-income group into one "great unwashed" group was an unnecessarily cruel way to address those not participating in the social media revolution.
  • 1 out of 10 U.S. adults now publish blogs (up from 5% last year) 1 out of 5 18-34-year olds publish blogs (up from 10% last year) 22% of U.S. adults use IM (up from 9% last year) 21% of 18-34-year olds use IM (up from 14% last year)
  • I think now it's taking off because social networks are taking off...People may have been doing it before, but may not have realized it. Now they're recognizing it for what it is."
  • Although these numbers look promising for our favorite genre, social media, they should probably be taken with a grain of salt. While we do believe that text messaging is an important method of communication, it doesn't quite fit with what the standard definition of social media is: blogging, social networking sites, and other web properties that engage collective groups of people to drive their content. We would like to see how the numbers really break down among the three "social media" activities they measured, but that data was not immediately available.
  • In exploratory qualitative research, we have undertaken indicates the consumer might take a broader view of what social media might mean. For example, it could be taken by consumers to mean any digital form of personal communication that helps enable peer collaboration and sharing. This softer, less-structured definition is possibly useful in determining possible future growth areas of personal social P2P media from a consumer-centric POV."

Wesch worldsim explained anti-teaching

shared by Barbara Lindsey on 06 Oct 11 - Cached
  • But while the sheer numbers of students are a burden in one sense, there is also tremendous potential. Think of the knowledge and life experience that is in that single room, if only I could find a way to harness it! I wanted the students to be fully engaged, talking to one another, grappling with interesting questions, and exploring any and all resources to find answers (and more questions). I wanted them to really get a strong sense of the importance of what we discuss in cultural anthropology. I wanted them to expand their empathy, to actually try to experience the life-worlds of others. Above all, I wanted them to recognize their own importance in helping to shape an increasingly globally interconnected world society.
  • World Simulation. Students are asked to imagine the world in the classroom. We create a map that mimics the geographical, environmental, and biological diversity of our real world. The map is laid onto a map of the classroom, and students are asked to imagine themselves living in the environment that maps onto them. The class is divided into 15-20 groups of about 12-20 students in each group. Each group is challenged to create their own cultures to survive in their own unique environments.
  • The creativity of the students in creating their cultures subverts any simple monocausal determinism (just as human creativity does in the real world). Environmental determinism is just one theory on the table as students try to create a reasonably realistic culture that could exist within their given environment. To add realism, students are required to provide comparisons to real life cultures at every step along the way, justifying why they have chosen to construct their culture in one way rather than another (sometimes creating elaborate histories to explain some unique characteristic). Three weeks before the end of the semester, all groups have completed their culture and submit a final ethnography to me. I read these over, and begin planning the main event: the world simulation.

  • To Orange, I will show an actual example of a map in my next full post and explain more about the parameters that are given and what the students fill in themselves. You raise a much more important question though, about the necessity of simplifying in order for the simulation to work. This aspect of the simulation almost led me to abandon the whole thing as I started to think it through and plan for it. Instead I found two ways to deal with it: 1. I challenge my students to tell me where the simulation is oversimplified and make their own case for how the simulation should change for the next time it is performed. This way they are not simply accepting our imaginary world “as is” and are instead actively thinking about how the real world works and how we may have misrepresented it in our simulation. (Even if the simulation fails miserably, it has succeeded in getting students to think about how the world works!) 2. I encourage the students to use the simplification as a canvas on which they can build and/or interpret complexity. In a lecture format I only have so much time to cover the effects of colonization – perhaps 50 minutes – not enough to really explore all of the different facets. In the World Simulation I can encourage each student to think about how colonization would affect their culture in multiple ways and at multiple levels (e.g. infrastructure, social structure, superstructure). Sometimes this is to complex to be incorporated into the simulation, but they are asked to do a reflection paper immediately following the simulation in which they write their own “cultural history.” This written format allows them to explore some complexities they might not have had the time or means to express in the simulation.
