Description

This set of scripts takes advantage of the BRÉF database compiled from research previously carried out by Fevrat et al. at Avignon University [LFM'20]. The results concerning the re-election of French elected officials presented in Noémie Fevrat's PhD dissertation [F'24] are based on these scripts.

If you use these scripts or the data they produce, please cite reference [F'24]:

Data

The scripts are meant to be applied to v1.0.2 of the BRÉF database, that describes representatives elected in France during the Fifth Republic (1958-present). This version is available within this GitHub repository, as well as on Zenodo.

Organization

Here are the folders composing the project:

• Folder data: state Legislative elected officials, legislature after legislature.
• Folder plots: plots generated by the scripts.
• Folder src : set of scripts.
  • Folder rotations : scripts relating to the study of re-election and rotation of members of the french Parliament from one legislature to the next under the Fifth Republic.
  • Folder sequences : scripts relating to the study of the longitudinal elective careers of each of the elected representatives in the database, using the sequence analysis method.

Installation

1. Install the R language
2. Download this project from GitHub and unzip the archive.
3. Use the src/install.R script to install the required packages.

Use

In order to replicate the experiments from the thesis, perform the following operations:

1. Open the R console.
2. Set the current projet directory as the working directory, using setwd("my/path/to/the/project/SignedBenchmark").
3. Run the script src/main_rotations.R for the rotation-related processing and src/main_sequences.R to perform the sequence analysis.
