In the context of the NCCR ‘on the move’ we are looking for 1 research assistant (15h/week; 130h) to support research on the politicization of immigration in newspapers. We are now looking for a conscientious and reliable research assistant. You should be matriculated at the University of Neuchâtel.
Correlations are some of the basics in quantitative analysis, and they are well suited for graphical examination. Using plots we can see whether it is justified to assume a linear relationship between the variables, for example. Scatter plots are our friends here, and with two variables it is as simple as calling plot() in R:
If we have more than two variables, it can be useful to plot a scatter plot matrix: multiple scatter plots in one go. The pairs() command is built in, but in my view not the most useful one out there. Here we use cbind() to combine a few variables, and specify that we don’t want to see the same scatter plots (rotated) in the upper panel.
pairs(cbind(var1, var2, var3, var4) , upper.panel=NULL)
A more flexible method is provided in library(car) with the scatterplotMatrix(). If this is not flexible enough, we can always split the plot and draw whatever we need, but that’s not for today.
library(car)scatterplotMatrix(cbind(var1, var2, var3, var4))
If we have many more variables, it’s necessary to draw multiple plots to be able to see what is going on. However, sometimes after having checked that the associations are more or less linear, we’re simply interested in the strength and direction of the correlations for many combinations of variables. I guess the classic approach is staring at a large table of correlation coefficients, but as is often the case, graphics can make your life easier, in this case library(corrplot):
This is certainly more pleasant than staring at a table…
For all these commands, R offers plenty of ways to tweak the output.
Research by my colleagues Rosita Fibbi, Robin Stünzi, Agota Sanislo, and Philipp Schnell on pathways to success is now available via video (in French and German). The research was supported by Fondation Mercator Suisse. The research shows immigrants overcoming their disadvantaged background to successfully integrate into work.
The SFM is now looking for a 2-year postdoc to work on a project on the political participation of naturalized citizens. The project wants to analyse the political preferences of naturalized citizens, the drivers to become active participants in left and right wing parties and how they make sense of their background with regard to the party’s discourses. This will be measured on the basis of content analysis and biographical interviews.
Deadline: 31 October 2018
