Extreme Right Bibliography Online

Over the last two decades I have accumulated thousands of references that have travelled with me all the way from bibtex-mode through Endnote, Citavi and some more obscure packages until we finally came full circle and ended up in bibtex-mode again. To my mild surprise, my use of (some) keywords has been fairly consistent so that it was relatively easy (using make, bibtool and bibtex2html) to create a 380+ entries strong online bibliography on the Extreme Right in Western Europe. Enjoy.

Source: Long/Freese, Regression Models for Categorical Dependent Variables Using Stata

[/caption] I use emacs/\LaTeXfor all my textprocessing needs, and for the last four or five years, I have created all my slides with Till Tantaus excellent “beamer” class. At the moment, I’m teaching a 2nd year stats course (imagine doing this with PowerPoint – the horror! the horror!), so I sometimes use graphs from the assigned text like this one from Long&Freese that illustrates the latent variable/threshold interpretation of the binary logit model. The message should be fairly clear: y^{*} depends on x andfollows…

How to get from Stata to Pajek

Archived; click post to view.
Excerpt: I’m teaching an introductory SNA class this year. Following a time-honoured tradition, I conducted a small network survey at the beginning of the class using Limesurvey. Getting the data from Limesurvey to Stata via CSV was easy enough. Here is the data set. But how does one get the data from Stata to Pajek for analysis? Actually, it’s quite easy. First, we need to change the layout of the data. In the data set, there is one record for each of the 13 respondent. Each record has 13 variables, one for each (potential) arc connecting the respondent to other students in…

Statistics and Data links roundup for November 23rd through December 29th

Statistics and Data links roundup for November 23rd through December 29th:

  • The Data and Story Library – DASL (pronounced “dazzle”) is an online library of datafiles and stories that illustrate the use of basic statistics methods. We hope to provide data from a wide variety of topics so that statistics teachers can find real-world examples that will be interesting to their students. Use DASL’s powerful search engine to locate the story or datafile of interest.

Data on Knowledge Networks in Political Science Published

Article on Networks in Political Science Published

Harald’s and my article on citation and collaboration networks in German and British Political Science has finally appeared in print and online, which is obviously great. Here is the abstract:

Citations and co-publications are one important indicator of scientific communication and collaboration. By studying patterns of citation and co-publication in four major European Political Science journals (BJPS, PS, PVS and ÖZP), we demonstrate that compared to the conduits of communication in the natural sciences, these networks are rather sparse. British Political Science, however, is clearly less fragmented than its German speaking counterpart.

Weighting Survey Data: Not Necessarily a Brilliant Idea

Archived; click post to view.
Excerpt: Should one weight their survey data? Is it worth the effort? The short answer must be ‘maybe’ or ‘it depends’. A slightly longer and much more useful answer was given by Leslie Kish in his enormously helpful paper ‘Weighting: Why, when and how’. Today (well, actually I submitted the final manuscript 2.5 years ago – that’s scientific progress for you!), I have added my own two cent with a short chapter that looks at the effects and non-effects of common weighting procedures (in German). The bottom line is that if you employ the usual weighting variables (age, gender, education and…

Is salience a cause or a consequence of radical right electoral support?

Archived; click post to view.
Excerpt: In my pet model, the salience of issues such as immigration or national identiy in the manifestos of established parties

Random shock to salience - support cannot be bothered to react

[/caption] makes a vote for the extreme right/radical right much more likely. There is, however, a potential problem with this argument: if radical right support is stable in the medium term, and if other parties react to past successes for the radical right by modifying their manifestos, this relationship might be spurious. In my paper for the ECPR conference at Potsdam, I use a time-series model …
