datamining maps visual graphic

shared by Barbara Lindsey on 09 Jun 10 - Cached
  • 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

plagiarism highered stduents

shared by Barbara Lindsey on 08 Jun 10 - Cached
  • To me it meant that there were contradictions about what we did and what we said in our culture about who we looked up to and who we made pay for our sins. It also meant that authorship and authoring were far more complicated than could be taught—I myself was about to see this, live it.
  • Because she had a disciplinary file in the dean’s office, she decided against graduate school and didn’t take the GRE, though she was thinking about graduate school in business. More importantly, though, her self-image as a good girl had been crushed.
  • I told Haley a bit about how her plagiarism had affected me. How I took it personally, and trusted students a little less; I made sure that assignments were plagiarism-proof. But what she couldn’t know was how I became more confident in spotting an opportunity to instruct, and less interested in policing boundaries—which were, after all, mine to teach. She also couldn’t know that at one point, I’d considered designing a course that would focus on rewriting, rephrasing, riffing, and appropriation as real tools of the writer’s trade. It wouldn’t teach anything that would get anyone in trouble, but unlike other writing courses, it would be honest about where ideas and language come from: well, who knows where they come from, but not from angelic transmissions into our minds.
