Citation Map Shows Top Science Cities

mikejuk writes "Which cities around the world produce not just the most but the best scientific papers? Using a database and Google Maps the answer is obvious. A paper at Physics arXiv describes how two researchers combined citation data with Google maps to create a plot showing how important cities around the world were in terms of their contribution to physics, chemistry or psychology."

  2. misleading metrics by Hazel+Bergeron · · Score: 5, Interesting

    "Number of links" has always struck me as an odd metric (see also PageRank). The greatest work from the PoV of scientific advancement isn't necessarily the most cited. The greatest determinant will be how fashionable a particular field is - a few leading researchers in a particular field are likely to have a huge number of cites, especially if they constitently reach the well-known publications, but it doesn't necessarily mean the field is very scientifically interesting.

    Then, even if great progress has been made, you get the effect that people don't necessarily cite the seminal investigations so much as the pioneering refiners.

    Another interesting effect, of course, is the difference between provenance of researcher and location of publication. The US and the UK are particularly good at draining other countries of already well-educated people, but this doesn't mean that the US or the UK have performed the academic preparation necessary to produce excellent researchers.

      If you read the paper or click on the maps you will actually see that they DO NOT CORRECT for local population density. So, the metric in question is absolute rather than "per capita" productivity. This doesn't entirely invalidate it, but it calls into question how you would verbalize or interpret the results.

      I mean, if 8 of the top 10 cities for science *by any metric* are also 8 of the top 10 cities by population you have said something less interesting. These cities are already top cities for "being" at all. :-)

      It would be far more interesting to normalize in a per capita sense. There are clearly some major outliers in that sense scrolling around on the map. Vancouver lept out at me, but I'm sure others could find them as well. Now, wouldn't it be nice if the fancy visualization researchers helped us along in that task? :-)

      Local population density is pretty irrelevant here, too, unless your question is "what is the probability that I will meet the author of a journal article while walking down the street?" (To be fair, that is something one might be interested in when choosing where to live, but even in large cities there are often university enclaves near campus.) If you put a university with ten thousand students in a city of a million people, all other things being equal there's no reason why its scientific output ought to differ from a ten-thousand-student university in a 'college town' with just fifty thousand residents. The size of the circle in Los Angeles has nothing to do with the city itself, and everything to do with the output of UCLA.

      More interesting would be something like number and quality of publications normalized according to the number of graduate students and postdocs (since they're the ones who are most likely doing the actual hands-on research) in the city.

  8. Psychology Map May Be Incorrect by schwnj · · Score: 3, Interesting

    In looking at the psychology map, I am suspicious that the authors made a minor error in their data collection. The database they used (Web of Science, Science Citation Index) does contain a category for psychology; however, it lists only the 71 psychology journals that are in the physiological/cognitive subfields of psychology. The overwhelming majority of psychology journals (almost 500 of them) are not in those fields, so the search should have also included the Social Science Citation Index data (also part of the Web of Science, just involves clicking another box). I suspect the authors only used the Science (and not Social Science) database because the data displayed on the map seems to over-represent programs that are strong in physio/cognitive, and under-represents (or ignores) programs that are strong in social, developmental, and clinical psychology.

    Since it used the scientific method? Don't take my word for it - try reading some papers on working memory, psychophysics or the statistics of psychometrics to realise that psychs have to have a stronger understanding of the scientific method than most other scientists. FYI, read the real papers not the type of nonsense that comes from critical analysis.

    Word is now extremely standard in academics, including engineering and science disciplines. The reason is that what the researchers are interested in is actually getting their ideas out to the world, not proving they are toughguys by using TeX. What you use to create doesn't matter all that much since journals are very much saying "Give us a PDF," they don't really care how it was created. So you just choose what is easiest for you to do your paper in that looks good and can export to PDF. Word plus Mathtype can do a nice, easy, job of formatting equations visually, and gets you all the spell checking and other functions of Word.

    I work for an engineering department at a research university (doing computer support) and we see more Word usage than anything else. Some researchers still like TeX, but they are in the minority these days.

    If you want to be a tough guy (hiding behind an AC post) about only TeX based papers being "real" scientific papers go ahead, however realize the world has moved on and left you behind.

  17. I'm not at all biased by Sycraft-fu · · Score: 3, Insightful

    I don't give a shit. My job isn't selling software, it isn't publishing papers, it isn't writing papers. It is supporting computers of people who write papers. A side effect of this job is that I get to see what software they need. Our top requested apps (to the point they are part of the standard install)? Word and Matlab. TeX is not on that list. That isn't to say it is gone, just that it is in minority use. The people who need it request it special (usually MikTeX and Winedt).

    The other software highly requested, though less now, is Acrobat, the full thing, to turn documents in to PDFs to go to the journals. These days the Word users tend to just use the included MS plugin, though some still like the full Acrobat. All the TeX types use Acrobat because it makes conversion real easy (you just print to the distiller and it makes a PDF of it). For the few grad students that use TeX it is usually CutePDF since that's free and generally does fine with PDF generation.

    The reason for my "tough guy" remark is his attitude that it is "infuriating" to see something written in anything but TeX. This has the attitude of "I spent all this time learning it, everyone else should have to to! You aren't a REAL man unless you do!" The content should matter, not the tool, to someone who actually cares about what is being said and isn't being silly about it.

    Times change. Deal with it. If you don't like Word because it is proprietary (by the way if you think that is the only proprietary thing used in research you are in for a nasty, nasty, surprise) then maybe you need to work on an open tool that is just as easy to use. The researchers aren't interested in OSS zealot arguments, they are interested in getting their shit done and for many of them Word is easier. If there were a free tool that was as good, perhaps they'd be interested in that. Never met the researcher that didn't want to save a dollar whenever they can.

    Don't just bitch though because you spent time learning TeX and are mad that others don't have to.

      It is infuriating because of the difference in output quality, not because Word is proprietary or whatever other reason. Can you guess how the first poster was able to know the article was typeset using Word ? The paragraphs of text are not justified, the 'fi' ligature are not made, formulas are awful, the link for figure 1 is separated from the picture by a page break, etc.

      Actually, it is not actually Word's fault here, it is just a very badly typeset paper and one can do much better with Word.

      I also didn't understand your remark about TeX types using Acrobat and CutePDF. You do know that TeX will already output a PDF without conversion step necessary, right ? Why would they want to generate a PDF ?
