R starter resources

I’m hardly the first person you would want to talk to about learning statistics in R. But if you’re bent on teaching yourself R, and you’ve ended up at my blog, here are some resources I found useful. (No opinions here about whether R is good/bad better/worse than Excel, Minitab, Matlab, Octave, SPSS, Stata, SAS, … Continue reading

World Bank opens access to WDI

The World Bank has opened access to a flagship dataset that was mostly closed. Until recently, only a fraction of the thousand-plus data series that comprise the World Development Indicators (WDI) were available to non-paying customers in advanced economies. As of April 10, 2010, the World Bank has opened access to the complete dataset.

Fuzzy Thinking on African Botnets

I call “bull.” African botnets are not WMD, and the solution to African botnets is not to prosecute the lucky few who have computers there. Franz-Stefan Gady is completely out of touch with the realities of IT in Africa. The last thing African governments need is shunt scarce resources into prosecuting cyber criminals, particularly within … Continue reading

Equations in your dissertation

What do you use to edit equations for your dissertation? OpenOffice has a LaTeX equation editor plugin that takes latex input. You can enter in LaTeX equations, and then choose the resolution and file format in which you’d like a graphic inserted into your paper. Fantastic! Even better, its name is OOolatex. Who can resist … Continue reading

Coding Qualitative Data: Web Solution

Professor Stuart Schulman of University of Massachusetts (formerly University of Pittsburgh) designed a web server to provide qualitative data analysis (QDA) via web for social science datasets. The solution is called QDAP, currently housed at UMass but also at Pitt. Bravo! Free, multi-user, qualitative data analysis for anyone with a web browser. They have clearly … Continue reading

Skype sound configuration under Linux 9.10

Disclalimer: The settings under Ubuntu 9 are markedly different from my earlier post. I’ll try to post an update here with different instructions. The naming convention under Ubuntu 9.10 Koala’s sound mixer appear to be far more straightforward. Manual gain settings still did better than the default. –UPDATE

Transcriber for DIY interview transcription

Some day we’ll all have grants big enough to outsource our transcription needs. I have to say I was pleased with the performace of the free and open source Transcriber software. No need for new hardware (read, foot pedals) or mouse clicks while transcribing. The software loads an audio clip and provides simple keystrokes for … Continue reading

Coding Qualitative Data

A friend of mine recently pointed me towards MAXQDA for coding and parsing qualitative research. Too bad I just wrote a post on how garden-variety relational databases could be hornswoggled for the task. I was so proud of my handwritten beta, too…. A couple of quick web searches turned up NVivo and XSight, by QSR, … Continue reading

Skype sound configuration in Linux

As my readers know, recently I have been looking at Skype configuration for recording interviews here. [Ed– What readers?] Skype on Linux has the great advantage of a high-quality, free call recorder, Skype Call Recorder, of uncertain provenance. (Read, install at your own risk. Their website doesn’t list much about the authors, and it’s not … Continue reading

Tracking research interactions

How much information should the researcher keep about each site? Each interview? The answer, of course, is “all of it.” This can be an enormously time-consuming task, depending on the richness of the information the interviewer needs to collect about the site, the subject, and the interview instrument to be used. Relational databases are purpose … Continue reading
